Method: A total of 80 acute response period of pancreatitis patients who received treatment at Zhangzhou Traditional Chinese Medicine Hospital from June 2021 to June 2022 were selected as the subjects of this study. They were randomly divided into experimental group and control group using a random number table method, with 40 patients in each group. The control group received routine nursing, while the experimental group received integrated traditional Chinese and western medicine nursing on the basis of the control group. The clinical symptom recovery time, serum inflammatory factors [interleukin-6 (IL-6), interleukin-15 (IL-15), tumor necrosis factor-α (TNF-α)] levels, intestinal barrier function [serum amylase (AMS), D-lactate, and diamine oxidase (DAO)] and incidence of complications between the two groups were compared. Result: The recovery time of clinical symptoms in the experimental group were significantly earlier than those in the control group, the differences were statistically significant (P<0.05). After intervention, the levels of IL-6, IL-15, TNF-α in the experimental groups were significantly lower than those in the control group, the differences were statistically significant (P<0.05). After intervention, the levels of AMS, D-lactate, and DAO in the experimental group were significantly lower than those in the control group, the differences were statistically significant (P<0.05). The incidence of complications in the experimental group was significantly lower than that in the control group, the differences were statistically significant (P<0.05). Conclusion: The application of integrated traditional Chinese and western medicine nursing in the acute response period of pancreatitis patients can accelerate the recovery of clinical symptoms, reduce inflammatory reactions, strengthen intestinal barrier function, and reduce the incidence of complications.

TEST PRINCIPLEThe UPSTATE® colorimetric STAR (Signal Transduction Assay Reaction) ELISA kit is a solid phase sandwich enzyme linked immunosorbent assay that provides a fast, sensitive method to detect specific levels of signaling targets in whole cell extracts. The GSK-3β plate is coated with a specific mouse monoclonal GSK-3β capture antibody on the microwells of the 96-well clear plate. Sample lysate or the standard included in the kit is incubated in the microwells allowing GSK-3βantigen to be captured in the plate wells. The plate is then washed to remove any non-bound unspecific material. The wells are then incubated with a specific rabbit anti-GSK-3β antibody to detect the captured GSK-3β on the plate well. The unbound detection antibody is washed away followed by incubation with an HRP-conjugated anti-rabbit antibody. This allows for a sensitive enzymatic detection of the sample. After the addition of TMB substrate and stop solution the absorbance is measured at 450 nm using a plate reader.The entire assay takes less than 5 hours to complete with minimal hands-on time. Many of the reagents are supplied in ready-to use formulations for ease of use. The kit also includes a standard that is run as both a positive control and to develop a standard line of detection.II. GSK-3β BACKGROUNDGlycogen Synthase Kinase-3 differs from most serine/threonine kinases in that it is active in the absence of the action of signaling pathways. When it becomes phosphorylated, the protein becomes inactive. There are two isoforms that exist, GSK-3α and GSK-3β. The function of GSK-3 is to phosphorylate Glycogen Synthase and thereby inactivate it. Insulin action stimulates the PI3 Kinase pathway that results in the activation of Akt. Akt phosphorylates GSK-3, thereby inactivating it. Glycogen Synthase, GSK-3’s downstream substrate, is then rapidly dephosphorylated and activated. Other GSK-3 substrates include Jun (on inhibitory sites), and eIF2B. Detection of GSK-3’s phosphorylation status of the Akt site (Ser21) on GSK-3 is suitable for surrogate assays of the activation state of the pathway.III.

PREPARATION OF SAMPLE1. Culture cells stimulating GSK-3β activation as desired.2. Remove culture media and wash cells twice ice-cold with 1X TBS (Tris Buffered Saline) or PBS (Phosphate BufferedSaline). Discard supernatant3. Add 5-10 mL of cold 1X RIPA containing 0.1% SDS and protease inhibitors per 150 mm tissue culture plate.Note: 10 mL of 1X RIPA containing 0.1% SDS can be prepared by adding 10 µL of 1 µg/µL Leupeptin, 10 µL of 1 µg/µL Aprotinin, 10 µL of 1 µg/µL Pepstatin, 100 µL of 100mM PMSF, 100 µL 10% SDS, 1 mL 10X RIPA (Cat. No. 20-188) to 8.77 mL of distilled or deionized water.4. Scrape cells from plate with a rubber policeman.5. Transfer cells in RIPA buffer to a microcentrifuge tube and incubate on ice for 15 minutes.6. Vortex tube for 10 seconds or sonicate briefly for 10 seconds.7. Clarify lysate by centrifugation at 12,000 rpm for 10 minutes at 4ºC in a microcentrifuge prior to use.8. Cell extract containing SDS must be diluted to 0.01% SDS using ELISA Diluent prior to use.9. Collect the supernatant and calculate protein concentration using a Bradford Assay or by densitometry.10. It is suggested that the cell lysate be used immediately following preparation. However, samples can be frozen andstored at -80º C for later use. Frozen samples should be used within 6 months if storing at -80º C. Avoid repeated freeze thaws.Further information of lysate preparation protocols can be obtained at Cell Lysate Extracts-General Protocols.VII. REAGENT PREPARATION1. 1X Wash BufferWarm the 25X ELISA Wash Buffer to room temperature and mix to ensure that any precipitated salts have re-dissolved. For 500 mL of Wash Buffer, combine 20 mL of 25X ELISA Wash Buffer and 480 mL distilled or deionized water. Stir to homogeneity. Wash Buffer can be stored for up to 4 weeks at 2-8°C. Discard the Wash Buffer if it becomes turbid or if a precipitate develops.2. Anti-Rabbit IgG HRP ConjugateDilute the anti-Rabbit IgG HRP Conjugate 100-fold with HRP Diluent immediately before use. Prepare 1 mL for each strip used.3. StandardNote : When opening lyophilized Standard, remove rubber stopper gently as the lyophilizate may have becomedislodged during shipping.Reconstitute the standard with the volume of ELISA Diluent specified on the vial label to give a concentration of 25 ng/mL. Gently swirl the vial and allow the vial to sit for 10 minutes to ensure the material is completely reconstituted. The standard should be reconstituted immediately before the assay. This stock material (tube #1) is then used to generate a standard curve. A suggested 2-fold dilution scheme is as follows:a) Label 7 test tubes #2-7 and “0 dose”. Add 150 μL of the ELISA Diluent to tubes #2-7 and “0 dose”.b) Add 150 μL of the stock Standard solution [25 ng/mL] to tube #2 and vortex. This is Standard tube #2 with aconcentration of 12.5 ng/mL.c) Standards #3-7 are then prepared by performing a 2-fold serial dilution of the preceding standard. Refer to Fig. 1.For example, to make Standard #3, remove 150 μL of Standard #2 and add it to tube #3 and vortex and so on. Do not add any Standard to the "0 Dose" Standard tube.Figure 1: Recommended 2-fold Serial Dilution of StandardNote: The Standard curve can set up with a different serial dilution scheme by making appropriate adjustments to the dilution pattern.25 12.5 6.25 3.13 1.560.780.39 ng/mL150 μL 150 μL 150 μL 150 μL 150 μL150 μLVIII.

Seal the plate and incubate at room temperature for 3 hours at 4. Add50room temperature (on shaker if possible).5. IMPORTANT WASH STEP:Gently remove the plate sealer and wash the plate at least 4 times. A thorough washing of the plate is extremely important to reduce background. We recommend using a multi-channel pipette to fill each well with 250 μL of diluted Wash Buffer. Fluid removal from the wells is best accomplished by inverting the plate over a sink and flicking the fluid out of the wells and then blotting the plate on clean paper towels.Using the multichannel pipet add 250 μL of Wash Buffer to each well; flick and blot the plate. Repeat this procedure for a total of 4 times.For users of automatic plate washers: It is important to ensure that the wash apparatus is properly maintained and operating correctly. Tubing and tips can easily become clogged, leading to incomplete washing and inadequate aspiration of wells. The result may be poor precision and an unsuitable standard curve. For best results, we recommend at least 4 wash cycles.μL of a 1:100 dilution of the anti-Rabbit IgG HRP Conjugate to each well. Cover the plate and incubate 6.

63256-200-04 PRESCRIBING INFORMATION NDCSTERILE TALC POWDERFDA FINAL VERSIONFor Intrapleural Administration OnlyDESCRIPTIONSterile Talc Powder is a sclerosing agent intended for intrapleural administration supplied in a single use 100 mL brown glass bottle, sealed with a gray, 20 mm stopper and covered with a flip-off seal. Each bottle contains a minimum of 5.0 g of Talc USP (Ultra 2000 Talc), either white oroff-white to light gray, asbestos-free and brucite-free grade of talc of controlled particle size. The composition of the talc is ≥ 95% talc as hydrated magnesium silicate. The empirical formula oftalc is Mg3 Si4 010 (OH)2 with a molecular weight of 379.3. Associated naturally occurring minerals include chlorite (hydrated aluminum and magnesium silicate.), dolomite (calcium and magnesium carbonate), calcite (calcium carbonate) and quartz. Talc is practically insoluble in water and in dilute solutions of acids and alkali hydroxides. The finished product has been sterilized by gamma irradiation.CLINICAL PHARMACOLOGYMechanism of ActionThe therapeutic action of talc instilled into the pleural cavity is believed to result from inductionof an inflammatory reaction. This reaction promotes adherence of the visceral and parietal pleura, obliterating the pleural space and preventing reaccumulation of pleural fluid.The extent of systemic absorption of talc after intrapleural administration has not been adequately studied. Systemic exposure could be affected by the integrity of the pleural surface,and therefore could be increased if talc is administered immediately following lung resection or biopsy.CLINICAL STUDIESThe data demonstrating safety and efficacy of talc slurry administered via chest tube for the treatment of patients with malignant pleural effusions are from the published medical literature. The following prospective, randomized studies were designed to evaluate the risk of recurrenceof malignant pleural effusions in patient with a variety of solid tumors. The studies comparedtalc slurry, instilled into the pleural cavity via chest tube, versus a concurrent control. In all studies, after maximal drainage of the pleural effusion, the investigator administered talc slurryvia the chest tube. Chest films documented response (defined as lack of recurrence of fluid for a period of time). Studies differed on the timing of the efficacy assessment. Zimmer et al. did notspecify the time required evaluations. Ong et al. specified the assessment at one month. Sorensen et al. specified the assessment at 3-4 months. The remaining studies assessed response at the completion of the follow-up period.Randomized Controlled Trials Using Talc Slurry as a Sclerosing AgentREFERENCE TREATMENT RESPONSE RATE EVALUABLE PTS*p value*RESPONSERATE ALL PTS*p value*Sorensen et al.

INDICATIONS AND USAGESterile Talc Powder, administered intrapleurally via chest tube, is indicated as a sclerosing agent to decrease the recurrence of malignant pleural effusions in symptomatic patients. CONTRAINDICATIONSNone knownWARNINGSNonePRECAUTIONS1. Future procedures: The possibility of the future diagnostic and therapeutic procedures involving the hemithorax to be treated must be considered prior to administering Sterile Talc Powder. Sclerosis of the pleural space may preclude subsequent diagnostic procedures of the pleura on the treated side. Talc sclerosis may complicate or preclude future ipsilateral lung resective surgery, including pneumonectomy for transplantation purposes.e in potentially curable disease: Talc has no known antineoplastic activity and should not be used alone for potentially curable malignancies where systemic therapy would be more appropriate, e.g., a malignant effusion secondary to a potentially curable lymphoma.3. Pulmonary complications: Acute Pneumonitis and Acute Respiratory Distress Syndrome (ARDS) have been reported in association with intrapleural talc administration. Three of the case reports of ARDS have occurred after treatment with a relatively large talc dose (10 g) administered via intrapleural chest tube instillation. One patient died one month post treatment and two patients recovered without further sequelae.DRUG INTERACTIONSIt is not known whether the effectiveness of a second sclerosing agent after prior talc pleurodesis would be diminished by the absorptive properties of talc.Carcinogenesis, Mutagenesis, Impairment of Fertility: Studies on the carcinogenicity of talc have been performed using non-standard designs which prevent firm conclusions on its carcinogenicity. With single intraperitoneal administration to mice at 20 mg and observation for at least 6 months or 4 weekly doses administered intraperitoneally at 25 mg/dose to rats with observation for at least 84 weeks, tumor incidence was not increased. In these studies the talcand its asbestos content were not characterized.Genotoxicity was tested in cultures of rat pleural mesothelial cells (RPMC) as unscheduled DNA synthesis (UDS) and sister chromatid exchanges (SCEs).None of the talc samples (which were asbestos-free) induced enhancement of UDS or SCEs in treated cultures. No information is available on impairment of fertility in animals by talc.Pregnancy: Pregnancy Category B. An oral administration study has been performed in the rabbit at 900 mg/kg. Approximately 5 fold higher than a human dose on mg/m2 basis, and has revealed no evidence of teratogenicity due to talc. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should not be used during pregnancy unless the benefit outweighs the risk.Pediatric Use: The safety and efficacy of Sterile Talc Powder in pediatric patients have not been established.Geriatric use: The estimated mean and median ages of patients treated with talc slurry from clinical studies (single-arm or randomized) were 60 and 62 years, respectively. No analyses to specifically evaluate the safety and efficacy in the geriatric population have been reported.ADVERSE REACTIONSIntrathoracic administration of talc slurry has been described in medical literature reports involving more than 2000 patients. Patients with malignant pleural effusions were treated with talc via poudrage or slurry. In general, with respect to reported adverse experiences, it is difficult to distinguish the effects of talc from the effects of the procedure(s) associated with its administration. The most often reported adverse experiences to intrapleurally-administered talc were fever and pain.Infection: Complications reported include empyema.Respiratory: Complications reported include hypoxemia, dyspnea, unilateral pulmonary edema, pneumonia, ARDS, brochopleural fistula, hemoptysis and pulmonary emboli. Cardiovascular: Complications reported included tachycardia, myocardial infarction, hypotension, hypovolemia, and asystolic arrestDelivery Procedure: Adverse reactions due to the delivery procedure and the chest tube may include: pain,infection at the site of thoracostomy or thoracoscopy, localized bleeding, and subcutaneous emphysema.Chronic Toxicity: Since patients in clinical studies had a limited life expectancy, data on chronic toxicity are limitedOVERDOSAGENo definite relationship between dose and toxicity has been established. Excessive talc may be partially removed with saline lavage.DOSAGE AND ADMINISTRATIONSterile Talc Powder should be administered after adequate drainage of the effusion. The success of the pleurodesis appears to be related to the completeness of the drainage of the pleural fluid, as well as the full re-expansion of the lung, both of which will promote symphysis of the pleural surfaces.The recommended dose is 5 g, dissolved in 50 - 100 ml Sodium Chloride Injection, USP. Although the optimal dose for effective pleurodesis is unknown, 5 g was the dose most frequently reported in the published literature.Talc PreparationPrepare the talc slurry using aseptic technique in an appropriate laminar flow hood. Remove talc container from packaging. Remove protective flip-off seal.Each brown bottle contains 5 g of Sterilized Talc Powder. To dispense the contents:ing a 16 gauge needle attached to a 60-ml LuerLok syringe, measure and draw up 50 ml ofSodium Chloride Injection, USP. Vent the talc bottle using a needle. Slowing inject the 50 ml of Sodium Chloride Injection, USP into the bottle. For doses more than 5 g, repeat this procedure with a second bottle.2.Swirl the bottle(s) to disperse the talc powder and continue swirling to avoid settling of thetalc in the slurry. Each bottle will contain 5 g Sterile Talc Powder dispersed in 50 ml of Sodium Chloride Injection, USP.3.Divide the content of each bottle into two 60 ml irrigation syringes by withdrawing 25 ml ofthe slurry into each syringe with continuous swirling.QS each syringe with Sodium Chloride Injection, USP to a total volume of 50 ml in each syringe. Draw air into each syringe to the60 ml mark to serve as a headspace for mixing prior to administration.4. When appropriately labeled, each syringe contains 2.5 g of Sterile Talc in 50 ml of SodiumChloride Injection, USP with an air headspace of 10 ml. Once the slurry has been made, use within 12 hours or discard and prepare fresh slurry. Label the syringes appropriately noting the expiration date and time, with the statement “For Pleurodesis Only – NOT FOR IV ADMINISTRATION,” the identity of the patient intended to receive this material and acautionary statement to SHAKE WELL before use.5. Prior to administration, completely and continuously agitate the syringes to evenlyredisperse the talc and avoid settlement. Immediately prior to administration, vent the 10ml air headspace from each syringe.6. Attach the adapter and place a syringe tip on the adapter. Maintain continuous agitationof the syringes.NOTICE: Shake well before installation. Each 25 ml of prepared slurry in the syringe contains 1.25 g of talc. NOT FOR IV ADMINISTRATION.AdministrationAdminister the talc slurry through the chest tube by gently applying pressure to syringe plunger and empty the contents of the syringe into the chest cavity. After application, discard the empty syringe according to general hospital procedures. After the talc slurry has been administered through the chest tube into the pleural cavity, the chest tube may be flushed with 10- 25 ml sodium chloride solution to ensure that the complete dose of talc is delivered.Following introduction of the talc slurry, the chest drainage tube is clamped, and the patient is asked to move, at 20 to 30 minute intervals, from supine to alternating decubitus positions, so that over a period of about 2 hours the talc is distributed within the chest cavity. Recent evidence suggests that this step may not be necessary.At the end of this period, the chest drainage tube is unclamped, and the excess saline is removed by the routine continual external suction on the tube.HOW SUPPLIEDNDC 63256-200-04 Sterile Talc Powder is supplied in a 100 ml brown glass bottle containing 5 g of talc.The sterile bottle is closed with a gray stopper and covered with a flip-off seal. Storage: Store at Room Temperature (18-25°C). Protect against sunlight.DISTRIBUTED BY: Bryan Corporation. Woburn, MA 01801Version: Original September 2003。

GSK461364_DataSheet_MedChemExpress

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:GSK461364 is a potent Polo–like kinase 1 (PLK1) inhibitor with a K i value of 2.2 nM.IC50 & Target: Ki: 2.2 nM (PLK1)In Vitro: GSK461364 inhibits cancer cell line proliferation from multiple origins with minimal toxicity in nondividing human cells [1].RNA silencing of WT p53 increases the antiproliferative activity of GSK461364. As many cancer therapies tend to be more effective in p53 WT patients, the higher sensitivity of p53–deficient tumors toward GSK461364 can potentially offer an opportunity to treattumors that are refractory to other chemotherapies as well as early line therapy for these genotypes. GSK461364 is a thiophene amide that inhibits purified Plk1 enzyme in vitro with a K i of 2 nM and has >100–fold selectivity for Plk1 compared with Plk2 and Plk3.GSK461364 is a potent inhibitor of cell proliferation causing 50% growth inhibition (GI 50) below 100 nM in most of the cell lines tested with limited toxicity against human nonproliferating cells. Inhibition of cell cycle progression is concentration dependent with initial delay at G2 phase at high GSK461364 concentrations and arrest at M phase at lower concentrations. Currently,GSK461364 is in a dose–escalation first–time–in–human trial. Cell lines with mutations in the TP53 gene tended to be more sensitive to GSK461364, and that inhibiting the p53 response by RNA silencing confers increased sensitivity in some p53 wild–type (WT) cells.Furthermore, these more sensitive cell lines also have increased levels of chromosome instability, a characteristic associated with TP53 mutations [2]. In preclinical testing, GSK461364 shows antiproliferative activity against multiple (>120) tumor cell lines and potently inhibits the proliferation of greater than 83% and 91% of these cell lines, with IC 50 values lower than 50 and 100 nM,respectively [3].In Vivo: Cell culture growth inhibition by GSK461364 can be cytostatic or cytotoxic but leads to tumor regression in xenograft tumor models under proper dose scheduling. GSK461364 shows clear antitumor activity in human tumor xenograft models [1]. GSK461364shows a dose–dependent mitotic arrest in mouse xenografts, which correlates with effects on tumor growth [2]. Intraperitonealadministration of GSK461364 causes regression or tumor growth delay in different xenograft models, including Colo205 xenografts.Suppression of Plk1 in vivo by using GSK461364 results in mitotic arrest with aberrant mitotic figures consisting of monopolar or collapsed mitotic spindles [3].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]Kinase reactions are performed in a final assay volume of 10 μL using the Z'–Lyte Assay kit (Ser/Thr peptide 16).Briefly, reactions contained 50 mM HEPES (pH 7.5), 10 mM MgCl 2, 1 mM EGTA, 1 mM DTT, 0.01% Brij 35, 0.01 mg/mL casein, 200 μM ATP, 200 μM Polo Box peptide (NH2–MAGPMQS[pT]PLNGAKK–OH), and 6 nM recombinant Plk1 (H6–tev–PLK 1–603). Plk1 ispreincubated for 60 min in the presence or absence of 0 to 1,000 nM GSK461364A. Reactions are then initiated by the addition of 2μM peptide. After 15 min at 23°C, reactions are quenched and processed according the Z'–Lyte protocol and read on an EnVision plate reader. Raw fluorescence values are converted to concentration of product formed using substrate and product standards. IC 50values are determined using a two–parameter fit (Hill coefficient and IC 50) using GraFit software. Because the potency of inhibitionProduct Name:GSK461364Cat. No.:HY-50877CAS No.:929095-18-1Molecular Formula:C 27H 28F 3N 5O 2S Molecular Weight:543.60Target:Polo–like Kinase (PLK)Pathway:Cell Cycle/DNA Damage Solubility:10 mM in DMSOfor GSK461364A is observed to vary as a function of the ATP concentration in a manner consistent with an ATP–competitive modeof inhibition, an upper limit for the K i*app for GSK461364A is determined by applying the Cheng–Prusoff relationship for a competitive inhibitor (ATP K m*app=16 μM) to the IC50 value obtained with 60 min preincubation of GSK461364A.Cell Assay: GSK461364 is dissolved in DMSO.[1]Cell lines grow in the recommended media at 37°C, 5% CO2 in a humidified incubator. Cells are plated in triplicate 96–well microtiter plates at 1,000 cells per well in culture media. GSK461364A dissolved in DMSO or negative control (0.1% DMSO) are added the following day, and one plate is harvested with 50 μL of CellTiter–Glo for a time 0 (T=0) measurement.Animal Administration: GSK461364 is formulated in vehicle [4% DMA/Cremaphore (50:50), pH 5.6].[1]Cells are implanted in Nude mice and grown as tumor xenografts. Dosing began when tumors achieve appr 100 mm3. GSK461364A or the vehicle [4%DMA/Cremaphore (50:50), pH 5.6] is given i.p. to mice every 2 d (q2dx6, q2dx12) or every 4 d (q4dx3) at nominal dose levelsof 25, 50, and 100 mg/kg/dose. Results are reported as median tumor volume for n=7 to 8 mice. Paclitaxel (30 mg/kg i.v.;q4dx3) is used as a positive control for comparison. Tumors are measured thrice a week with Vernier calipers, and tumorvolume is calculated from two–dimensional measurements using an equation approximating the volume of a prolateellipsoid [tumor volume mm3=(length × width2) × 0.5]. The maximum tolerated dose is defined as the highest dose that produces >20% mortality or >20% weight loss (appr 4 g). Antitumor activity is defined as tumor growth delay (TGD), partial regression (PR), or complete regression (CR). TGD represents the time differential between the treated and control tumors to reach a predetermined tumor volume of 1,000 mm3. PR is defined as a decrease in an individual tumor volume to one–half the initial starting volume for at least 1 wk (three consecutive measurements). CR is defined as a decrease in an individual tumor volume to <13 mm3 for at least 1 wk. References:[1]. Gilmartin AG, et al.

M2457可以提高细胞对仑伐替尼的敏感性.此外,有研究[6]还发现在耐药细胞中m7G甲基转移酶复合物的关键成分M E T T L1和WD R4上调,通过介导t R N A m7G修饰和调控T R I M28表达等途径促进了对仑伐替尼的耐药性[7].另外,N A T10的上调可以通过调节H S P90A A1m R N A a c4C的修饰水平维持H S P90A A1的稳定性,促进了内质网应激H C C的转移和仑伐替尼耐药作用[8].此外,Y R D C也在调节K R A S蛋白质翻译方面发挥作用,其低t6A修饰水平的t R N A降低了K R A S的翻译,从而介导肝癌细胞对仑伐替尼的耐药[9].当前,R N A修饰蛋白成为了治疗肿瘤耐药的新靶标,针对M E T T L3的小分子抑制剂已经应用于临床研究,为提升仑伐替尼治疗反应性提供了新的选择.1.2㊀非编码R N A非编码R N A是基因表达调控的关键因素之一.微小R N A s(m i R N A s)㊁长链非编码R N A s(l nGc R N A s)和环状R N A s(c i r c R N A s)通过影响转录㊁转录后修饰和翻译等生物学过程,对癌症的发生发展和肿瘤耐药发挥着双重作用[10].1.2.1㊀m i c r o R N A在仑伐替尼耐药的人肝癌细胞株H u h7和S MM CG7721中,CGM e t呈现过度表达和活化的现象.有研究[11]表明,m i RG128G3p通过抑制cGM e t表达,调节介导凋亡途径的A k t和调节细胞周期进程的E R K参与了仑伐替尼的耐药机制.此外,在仑伐替尼耐药的肝癌细胞中,A K R1C1和m i c r o R N A 464表达水平显著上调.数据库分析提示A K R1C1和m i c r o R N A464可能存在靶向关系,而m i c r o RGN A464被认为是早期诊断仑伐替尼耐药性的一个潜在生物标志物[12].1.2.2㊀l n c R N A在仑伐替尼耐药的H C C细胞中,L n c R N A MT1J P(MT1J P)呈现上调的情况,导致了MT1J P 和抗凋亡蛋白B C L2L2的过度表达,从而降低了H C C细胞对仑伐替尼的敏感性[13].MT1J P通过吸附m i RG24G3p来靶向B C L2L2,进而促进了仑伐替尼的耐药性.此外,有研究[14]报道了l n c X I S T通过激活H C C细胞中的E Z H2GN O D2GE R K轴来促进仑伐替尼的耐药性.S O N G等[15]观察到在仑伐替尼耐药的细胞和组织中P I N K1的高表达,这有助于维持线粒体的结构和功能,并促进抗氧化应激反应,进一步的机制研究发现F G D5GA S1/m i RG5590G3p/P I N K1轴可以促进肝癌细胞对仑伐替尼的耐药性.机制研究表明L I N C01607/m i RG892b/P62促进了线粒体自噬,降低了R O S水平,从而导致肿瘤的耐药性.最后,敲除L I N C01607联合仑伐替尼能够有效地克服类器官模型中仑伐替尼的耐药性[16].1.2.3㊀c i r c R N A通过对28例接受仑伐替尼治疗后出现耐药的患者进行外周血检测,发现c i r c M E D27水平显著上升.相关研究[17]表明,c i r c M E D27作为m i RG655G3p的竞争内源性R N A发挥着重要作用,其上调促使U S P28的表达增加,在肝癌的进展和仑伐替尼耐药过程中发挥关键作用.此外,L I U等[18]首次发现c i r c K C N N2通过m i RG520cG3p/M B D2轴抑制了H C C的复发.潜在的机制可能在于c i r c K C N N2和仑伐替尼都能够抑制F G F R4的表达,从而加强对仑伐替尼的抗肿瘤效果.H A O等[19]研究发现C i rGc P A K1通过H i p p o信号通路促进了Y A P的核转运,从而促进了H C C的进展.同时,该研究发现在仑伐替尼耐药的L M3GL R和H e pG3BGL R H C C细胞中,C i r c P A K1的表达上调.外泌体中高表达的C i r c P A K1从耐药细胞转运到敏感细胞,诱导细胞对仑伐替尼的耐药性.非编码R N A作为治疗靶点在改善肿瘤耐药方面显示出极具竞争力和前景.然而,在药物的稳定性和传递效率方面仍然存在挑战.28南昌大学学报(医学版)2024年4月,第64卷第2期2㊀信号通路与仑伐替尼耐药㊀㊀作为一种多靶点酪氨酸激酶抑制剂,仑伐替尼主要作用于血管内皮生长因子(V E G F R)1G3㊁成纤维细胞生长因子受体(F G F R)1G4等靶点,从而发挥抗肿瘤的作用.近期的研究逐渐揭示,仑伐替尼治疗导致V E G F R和F G F R的抑制,进而引发E G F R/ S T A T3㊁R A S/R A F/M E K/E R K㊁P I3K/A K T等相关信号通路的反馈激活.这些信号通路的激活被认为是引发肿瘤对靶向治疗产生耐药的关键机制.因此,通过针对H C C内部相关信号通路的交叉对话进行靶向阻断,成为解决耐药问题的一种有效策略.2.1㊀E G F R介导的信号通路J I N等[20]通过C R I S P RGC a s9基因筛选,确定了E G F R作为仑伐替尼的合成致死靶点.研究机制显示,仑伐替尼治疗抑制F G F R,进而导致E G F RGP A K2GE R K5信号轴的反馈激活.另一方面,HU 等[21]的研究表明,A B C B1在E G F R激活下以脂质筏依赖的方式被激活,从而显著增强了仑伐替尼的细胞排出作用.这种激活通过激活E G F R并刺激E G F RGS T A T3GA B C B1轴,导致对仑伐替尼产生耐药性.考虑到E G F R通路在肝癌靶向治疗中的关键作用,L I M等[22]利用c t D N A分析了肝癌患者在治疗前和治疗进展时E G F R途径的遗传变化.他们发现,在仑伐替尼治疗进展期间,患者显示出E GGF R的拷贝数增加(4.8拷贝G7拷贝)和E R B B2的激活突变(S310Y).这些E G F R/E R B B2的遗传改变可能是导致仑伐替尼耐药性的遗传机制之一.2.2㊀R A S/M E K/E R K信号通路耐药细胞中V E G F R2的表达以及其下游R A S/M E K/E R K信号轴显著上调,E T SG1被确认为介导V E G F R2相关的仑伐替尼耐药的原因.此外,槐定碱被发现能够降低E T SG1的表达,从而抑制耐药H C C细胞中V E G F R2及其下游R A S/ M E K/E R K轴的表达[23].L U等[24]发现N F1和D U S P9在H C C中是仑伐替尼耐药的关键驱动因素,研究者通过R N A i敲除和C R I S P R/C a s9敲除模型进一步阐明了N F1激活P I3K/A K T和MA P K/E R K信号通路的机制.另外,D U S P9激活MA P K/E R K信号通路,导致F O X O3失活降解,最终诱导耐药发生.在仑伐替尼耐药细胞中,发现3种血管生成细胞因子(V E G F㊁P D G FGA A㊁A n g)显著上调,加速了肿瘤血管生成,增加了获得性耐药的发生,同时观察到了MA P K/M E K/E R K信号通路的激活和E MT标记物的上调[25].2.3㊀其他信号通路HO U等[26]发现,I T G B8通过H S P90介导的A K T的稳定以及A K T信号的增强来调节仑伐替尼的耐药性.通过使用A K T抑制剂MKG2206或H S P90抑制剂17GA A G,可以使耐药细胞重新对仑伐替尼治疗产生敏感性.此外,另一项研究[27]指出,T HO C2可能通过W n t/βGc a t e n i n通路参与调控肝癌对仑伐替尼的耐药性.肿瘤细胞异常信号通路的激活在获得性耐药中是常见的机制,针对这些关键靶点进行有效干预是防治耐药的有效策略.例如,已证实E G F R抑制剂㊁cGM E T抑制剂以及M E K抑制剂在一定程度上可以逆转耐药现象,有望成为临床上的新对策.3㊀肿瘤微环境与仑伐替尼耐药㊀㊀肿瘤微环境构成了一个极为复杂的生态系统,由各种细胞㊁非细胞成分和分泌产物组成,它们之间的相互作用形成了复杂的保护和修复机制,从而导致肿瘤产生耐药性.因此,深入探索新的针对微环境的靶向策略和药物,以改善耐药性并抑制肿瘤的恶性增殖显得尤为重要.作为一种抗血管生成药物,长期使用仑伐替尼可能会导致肿瘤细胞缺氧,部分细胞因此产生耐药性.在缺氧条件下,H I FG1α诱导P L C/P R F/5细胞中纤维连接蛋白的生成并削弱了仑伐替尼的作用,进而导致耐药性的产生.进一步的研究[28]表明,联合抑制纤维连接蛋白和MA P K通路可能是一种有效的治疗策略.肿瘤相关成纤维细胞(C A F)长期处于激活状态,形成致密的纤维间质包绕瘤块,通过分泌可溶性因子和直接细胞间接触等途径,对耐药性的形成起着潜在作用.研究人员发现,C A F和H C C细胞的共培养显著降低了H C C细胞对索拉非尼/仑伐替尼的体内外反应性.C A F分泌的S P P1通过P K Cα信号通路激活R A F/MA P K和P I3K/A K T/m T O R 通路,并通过E MT增强了肝癌患者对酪氨酸激酶抑制剂的抵抗.因此,治疗前血浆S P P1水平可能成为预测治疗反应的潜在生物标志物[29].4㊀细胞自噬与仑伐替尼耐药㊀㊀自噬是一种细胞死亡编程,与肿瘤的恶性演变和耐药性密切相关,过去的研究[30G31]已经表明在肝癌索拉非尼耐药中自噬发挥着关键作用,近期对仑伐替尼耐药机制的探索中也发现了类似的现象. P A N等[32]证实L A P T M5的上调会导致细胞自噬水平上升,从而降低H C C对仑伐替尼的敏感性,而38徐永康等:仑伐替尼在肝细胞癌中的耐药机制和对策研究进展通过L A P T M5的沉默或者使用H C Q来阻断内在的自噬潮,可以与仑伐替尼协同作用来抑制H C C 的生长.此外,HO A I R M1在仑伐替尼耐药细胞系中被发现是一个独立的耐药因子,与仑伐替尼治疗H C C的疗效显著相关.敲低HO T A I R M1可以增加H u h7GR和H e p G2GR细胞中m i RG34a的水平,并抑制B e c l i nG1的表达.因此,HO T A I R M1可能通过下调m i RG34a和上调B e c l i nG1来诱导自噬的激活,从而导致H C C对仑伐替尼的耐药性[33].5㊀铁死亡与仑伐替尼耐药㊀㊀铁死亡是一种铁依赖性的细胞死亡方式,诸多证据表明此过程与肿瘤治疗耐药相关联,调节铁死亡过程可能有效改善耐药性.I S E D A等[34]分析了仑伐替尼对H C C细胞的细胞毒性,并证实了仑伐替尼通过抑制F G F R4,抑制x C T表达并诱导脂质R O S积累的方式诱导H C C细胞发生铁死亡.此外,活化的N r f2抑制了仑伐替尼诱导的铁死亡,因此抑制N r f2的活化有望提高H C C细胞对仑伐替尼的敏感性,从而改善肝癌的耐药性.另一项研究[35]发现,K E A P1是驱动索拉非尼耐药的关键基因,K E A P1失活导致了K E A P1/N r f2途径的失活,通过上调N r f2下游基因和降低R O S水平,导致人类H C C细胞对索拉非尼的耐药性增加.同时,该研究还发现K E A P1的破坏抑制了仑伐替尼诱导的细胞活力下降,同时降低了对药物反应产生R O S的能力,这表明K E A P1也可能是仑伐替尼的易感基因之一.6㊀其他机制6.1㊀肿瘤细胞干性肿瘤干细胞(C S C)是一种功能细胞状态,具有自我复制和多谱系分化能力,在肿瘤药物抵抗中发挥关键作用,其耐药机制主要涉及药物转运子高表达㊁强D N A修复能力和募集保护性微环境等方面[36].WA N G等[37]研究发现F Z D10在肝C S C中高度表达,从机制上看,M E T T L3介导F Z D10m RGN A的m6A修饰,而m6A读取器Y T H D F2随后与F Z D10m R N A上的m6A位点结合,保持该m R N A 的稳定性.F Z D10通过WN T/βGc a t e n i n和H i p p o 途径增强肝脏C S C的特性,并且F Z D10/βGc a t e n i n/ cGJ u n/M E K/E R K轴促进肝癌细胞对仑伐替尼产生耐药性.采用腺相关病毒靶向F Z D10或βGc a t e n i n 抑制剂治疗仑伐替尼耐药H C C可恢复其抗肿瘤反应.另一项研究[38]表明,T M4S F1通过上调MY H9来调节N O T C H通路,进而促进肝癌中干细胞干性和仑伐替尼耐药性,且C D73通过上调S O X9的表达和增强其蛋白稳定性,在维持C S C性状方面发挥关键作用.C D73的过度表达使H C C 细胞对仑伐替尼产生显著的耐药性,同时也在维持肝癌索拉非尼和卡博替尼的耐药性中发挥作用.因此,将C D73作为靶点可能是根除C S C和逆转肝癌患者对T K I耐药性的一种有希望的策略[39].6.2㊀糖酵解H C C在缺氧和营养缺乏的环境中,通过适应性机制 W a r b u r g效应 ,优先依靠糖酵解产生能量,相关的转运蛋白㊁关键限速酶和代谢产物能够通过多种机制促使肿瘤进展和耐药.因此,探索糖酵解调控的耐药机制对于癌症治疗具有重要意义.A CGY P1在糖酵解中扮演直接调节的角色,并通过A CGY P1/H S P90/MY C/L D H A轴驱动了仑伐替尼耐药性和H C C的进展,靶向A C Y P1可以与仑伐替尼协同作用,更有效地治疗H C C[40].另外,果糖G2,6G二磷酸酶3(P F K F B3)是糖酵解的有效刺激剂, P F K F B3的表达上调可以导致H C C细胞对仑伐替尼的耐药.联合使用P F K F B3抑制剂可以在仑伐替尼耐药后抑制P F K F B3及MM P s的表达,从而逆转H C C细胞对仑伐替尼的耐药性[41].7㊀逆转耐药的机制策略和临床对策7.1㊀机制策略7.1.1㊀E G F R抑制剂J I N等[20]在体外和体内实验中,利用E G F R抑制剂吉非替尼和仑伐替尼的联合作用于表达E G F R 的肝癌细胞系㊁异种肝癌细胞系㊁免疫活性小鼠模型以及病人来源H C C异种移植肿瘤,均观察到显著的抗增殖效果.进一步的临床试验(N C T04642547)结果显示,对于12例经过仑伐替尼治疗后肿瘤仍然进展的E G F R高表达肝癌患者,采用仑伐替尼和吉非替尼联合治疗后,4例部分缓解,4例病情稳定,显示出良好的应用前景.此外, S U N等[42]的研究表明,E G F R抑制剂吉非替尼与仑伐替尼联合应用能够延缓仑伐替尼耐药细胞的增殖并诱导其凋亡,其机制可能是通过抑制E G F R介导的M E K/E R K和P I3K/A K T通路激活.在体内实验中,仑伐替尼与依拉昔达或吉非替尼联合给药抑制了肿瘤生长和血管生成.HU等[21]发现另一种E G F R抑制剂厄洛替尼可以抑制A B C B1,从而减少仑伐替尼的胞吐,在体外和体内实验中均表现出对H C C的抑制效果.7.1.2㊀M E K抑制剂L U等[24]发现一种小分子M E K途径抑制剂曲48南昌大学学报(医学版)2024年4月,第64卷第2期美替尼可逆转H C C细胞中N F1和D U S P9丢失引起的耐药性,即使在小鼠中敲除N F1,曲美替尼仍然能有效阻止H C C的增殖.此外,HU A N G等[43]发现M E K抑制剂S e l u m e t i n i b能够消除D U S P4缺乏引起的仑伐替尼耐药性,表明M E K磷酸化和D U S P4抑制依赖性E R K激活是其耐药性产生的关键.7.1.3㊀其他有研究[44]表明,双硫仑联合铜离子能够增加仑伐替尼对仑伐替尼耐药肝癌细胞H u h7的敏感性,其机制可能与抑制P I3K/A k t通路及促进c a s p a s eG9蛋白表达有关.H AMA Y A等[45]发现化疗也是改善耐药的有效方式,顺铂能够抑制仑伐替尼耐药细胞的增殖,并诱导G2/M细胞周期阻滞.此外,顺铂通过A T M/A T RGC h k1/C h k2信号通路触发D N A损伤反应.另外,Z H A O等[23]发现槐定碱可以进一步提高仑伐替尼治疗仑伐替尼耐药H C C的敏感性.7.2㊀仑伐替尼耐药临床对策仑伐替尼已被证明是晚期H C C患者的一线治疗药物,在临床实践中得到了广泛应用.然而,一旦患者出现对仑伐替尼的耐药,目前尚缺乏标准有效的二线治疗方案.当患者出现仑伐替尼耐药时,通常是各临床中心根据自身实际经验选择治疗方式.7.2.1㊀分子靶向治疗抗血管生成药物作为治疗肝癌的重要药物,在仑伐替尼耐药后仍然是临床实践中的有效手段.根据当前的指南推荐,索拉非尼㊁瑞戈非尼㊁雷莫芦单抗等均是仑伐替尼治疗耐药患者的备用方案.T OMO N A R I等[46]首次报道了13名在仑伐替尼进展后接受索拉非尼治疗的患者.根据m R EGC I S T标准,O R R和D C R分别为15.3%(2/13)和69.2%(9/13).而根据R E C I S T标准,O R R和D C R分别为0%(0/13)和69.2%(9/13),中位P F S 为4.1个月.一项系统评价[47]分析了4054名患者的20项研究,发现进展后生存期(P P S)与总生存期(O S)之间存在更强的相关性(r=0.869,P<0.001).该评价同时探讨了P P S在仑伐替尼耐药患者中的作用,25例接受二线索拉非尼治疗的患者的O R R和D C R分别为12%(3/25)和52%(13/25),P F S为5.7个月(95%C I:0.8~10.6个月).另外,一项来自韩国的研究[48]提示,续贯索拉非尼是一种潜在的治疗选择.该研究发现,索拉非尼治疗的患者的中位O S明显长于接受纳武利尤单抗治疗的患者的中位O S(8.7v s3.0个月;P=0.046).索拉非尼治疗与较低的死亡率相关(H R=0.194;95%C I:0.053~0.708;P=0.013).另外,7例H C C患者在仑伐替尼失败后接受雷莫芦单抗作为二线或三线治疗,D C R为28.6%(2/7例),中位P F S为41d,具有抑制先前接受仑伐替尼治疗的患者H C C进展以及在治疗期间维持肝功能的潜力[49].由于肝癌患者发病机制的复杂性,导致药物疗效存在差异性,因此,目前临床对于药物耐药评价以及换药指征把控存在一定差异.一些临床工作者认为,仑伐替尼的高缓解率和低毒性仍会使患者受益.一项通过倾向性匹配来自11家不同医疗机构的临床数据的研究[50]发现,相较于其他治疗(包括最佳支持治疗㊁索拉非尼㊁瑞戈非尼㊁雷莫芦单抗),继续仑伐替尼治疗的患者可以获得更好的O S(10.8/19.6v s 5.8/11.2个月,P<0.001).7.2.2㊀免疫联合靶向治疗多项免疫联合靶向治疗的优异疗效已经深刻改变了肝癌的系统治疗格局,这些相互联合的治疗方案能够增强治疗效果,其在晚期二线治疗中的应用也在逐渐增加.Z O U等[51]进行了一项回顾性调查,评估了标准剂量的仑伐替尼与P DG1抑制剂的联合治疗对于仑伐替尼治疗进展患者的有效性和安全性,他们发现O R R和D C R分别为23.9%(11/46)和71.7%(33/46),而中位P F S和O S分别为6.9个月和14.5个月.最常见的治疗相关不良事件包括厌食症(43.5%)㊁甲状腺功能减退症(43.5%)和高血压(36.9%),而3/4级不良事件的发生率为34.8%(16/46).另一项研究[52]则比较了在仑伐替尼治疗失败患者中,P DG1联合仑伐替尼和瑞戈非尼治疗的效果,结果显示联合组的中位P F S和D C R 较单药组有所提高(P F S8.7v s4.2个月,P=0.018;D C R82.7%v s53.3%,P=0.01).然而,联合组的O S并未显示出显著的获益(15.3v sN E个月,P=0.5),且O R R也未显著高于瑞戈非尼组(27.6%v s13.3%,P=0.49).此外,瑞戈非尼组和联合组的3/4级治疗相关不良反应发生率分别为26.7%和10.3%,最常见的不良反应包括丙氨酸氨基转移酶升高㊁疼痛和总胆红素升高.然而,来自广州医科大学附属第二医院朱教授团队[53]和笔者团队的研究[54]显示,瑞戈非尼联合P DG1抑制剂相较于瑞戈非尼单药治疗在索拉非尼及仑伐替尼一线治疗失败后具有更高的O R R㊁更长的P F S和更好的O S.不过,纳入一线仑伐替尼治疗失败的患者比例较低可能是导致这些研究结果不一致的原因之一.目前,文献报道索拉非尼或免疫联合靶向药58徐永康等:仑伐替尼在肝细胞癌中的耐药机制和对策研究进展物可能存在一定的获益,但缺乏充分的临床数据支持.仑伐替尼耐药后的治疗方案仍处于探索阶段,但包括C h i C T R2200062854㊁C h i C T R2000036664㊁N C T05718882㊁N C T04642547等临床试验正在进行中.期待未来会有更多的大型临床研究集中于仑伐替尼耐药患者,以及探索免疫治疗联合仑伐替尼耐药后的治疗方案选择.参考文献:[1]㊀R UM G A Y H,A R N O L D M,F E R L A YJ,e t a l.G l o b a l b u r d e n o f p r i m a r y l i v e rc a n c e r i n2020a

·药物与临床·糖尿病新世界 2023年3月DOI:10.16658/ki.1672-4062.2023.05.059恩格列净联合西格列汀治疗老年2型糖尿病患者的临床疗效分析臧道军,龚红燕江苏省常州市德安医院老年内科,江苏常州213000[摘要]目的探讨老年2型糖尿病患者使用恩格列净+西格列汀治疗的临床效果。

方法选取2020年1月—2021年12月常州市德安医院接诊的100例老年2型糖尿病患者作为研究对象,根据不同用药方式分为对照组与研究组,各50例,对照组接受西格列汀治疗,研究组接受恩格列净+西格列汀治疗,就两组患者血糖指标、炎性指标、胱抑素C(Cys-C)、血尿素氮(BUN)、血同型半胱氨酸(Hcy)指标进行比较。

结果治疗前两组血糖指标相比,差异无统计学意义(P>0.05),治疗后,研究组HbA1c、FPG及2 hPG明显低于对照组,差异有统计学意义(P<0.05);治疗前两组炎性指标比较,差异无统计学意义(P>0.05),治疗后,研究组IL-4、IL-6及TNF-α明显低于对照组,差异有统计学意义(P<0.05);治疗前两组Cys-C、BUN及Hcy相比,差异无统计学意义(P>0.05),治疗后,研究组患者Cys-C、BUN及Hcy明显低于对照组,差异有统计学意义(P<0.05)。

结论对于老年2型糖尿病患者开展恩格列净+西格列汀治疗能有效改善血糖指标,降低Hcy,提升肾功能,治疗效果显著。

The cases were divided into control group and study group according to different medication administration, fifty cases in each. The control group received sitagliptin treatment and the study group received empagliflozin + sitagliptin treatment. The blood glu⁃cose index, inflammatory index, cystatin C (Cys-C), blood urea nitrogen (BUN), and blood homocysteine (Hcy) index were compared between the two groups.Results There was no statistically significant difference in blood glucose in⁃dexes between the two groups before treatment (P>0.05). After treatment, HbA1c, FPG and 2 hPG of the study group were significantly lower than those in the control group, the difference was statistically significant (P<0.05). There was no statistically significant difference in inflammatory indexes between the two groups before treatment (P>0.05). After treatment, IL-4, IL-6 and TNF-α in the study group were significantly lower than those in the control group, the dif⁃ference was statistically significant (P<0.05). There was no statistically significant difference in the Cys-C, BUN and Hcy between the two groups before treatment (P>0.05). After treatment, the Cys-C, BUN and Hcy of the study group were significantly lower than those in the control group, the difference was statistically significant (P<0.05).Conclusion For elderly patients with type 2 diabetes mellitus, treatment with empagliflozin + sitagliptin can effec⁃tively improve blood glucose index, reduce Hcy and enhance renal function, with significant therapeutic effects.[作者简介]臧道军(1974-),男,本科,副主任医师,研究方向为老年内科。

Click here for a list of recommended Microplate Readers.If using a Molecular Devices’ plate reader supported by SoftMax® Pro software, a preconfiguredprotocol for these CatchPoint SimpleStep ELISA Kits is available with all the protocol andanalysis settings at .The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and areporter conjugated detector antibody which immunocapture the sample analyte in solution. Thisentire complex (capture antibody/analyte/detector antibody) is in turn immobilized viaimmunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples orstandards are added to the wells, followed by the antibody mix. After incubation, the wells arewashed to remove unbound material. CatchPoint HRP Development Solution containing theStoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRPgenerating a fluorescent product. Signal is generated proportionally to the amount of boundanalyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nmExcitation/Cutoff/Emission.Notes There are four classes of immunoglobulins in rat: IgA, IgE, IgM, and IgG. IgG is the most abundantimmunoglobulin and is equally distributed in blood and tissue. In rat, the IgG class is furtherdivided into four subclasses: IgG1, IgG2a, IgG2b, and IgG2c. The general immunoglobulinstructure is composed of four polypeptide chains, two heavy and two light chains linked togetherand to each other by disulfide bonds, creating a tetrameric quaternary structure. The resultingtetramer creates two identical halves which together form a Y like structure. While the amino-terminal portions that exhibits highly variable amino-acid composition are involved in antigenbinding, the C terminal constant parts are involved in complement binding, placental passage andbinding to cell membrane.IgG is involved in response to a foreign antigen and the presence of IgG usually signifies a matureantibody response. IgG has a molecular weight of about 150 kDa, can bind to many pathogensand also plays an important role in antibody dependent cell-mediated cytotoxicity. Typically ratserum and plasma samples contain about 7 to 10 mg/ml of IgG.Platform Pre-coated microplate (12 x 8 well strips)PropertiesStorage instructions Store at +4°C.

Excessive freeze/thawing is not recommended. Expiry:When stored under the recommended conditions and handled correctly, full activity of the kit is retained until the expiry date on the outer box label.Quality Control:SensiMix SYBR ®Hi -ROX Kit and its components are extensively tested for activity,processivity, efficiency, heat activation, sensitivity, absence of nuclease contamination andabsence of nucleic acid contamination prior to release.Safety Precautions:Please refer to the material safety data sheet for further information.Notes:For research or further manufacturing use only. Trademarks:SensiMix, SensiFAST (Bioline Reagents Ltd), SYBR (Molecular Probes), ROX, LightCycler (Roche), StepOne (ABI), RotorGene (Qiagen), LightCycler (Roche).Kit componentsStore at –20 °CThe SensiMix SYBR ® Hi -ROX Kit has been optimized for use in SYBR ® Green -based qPCR on the real -time instruments listed in the following compatibility table, each of these instruments having the capacity to analyze the qPCR data with the passive reference signal either on or off. The kit is also compatible with several instruments that do not require the use of ROX, such as the BMS Mic, Qiagen Rotor -Gene ™ 6000, Bio -Rad CFX96 or Roche LightCycler ® 480.DescriptionThe SensiMix ™ SYBR ® Hi -ROX Kit is a high -performance reagent designed for superior sensitivity and specificity on various real -time instruments. The SensiMix SYBR ® Hi -ROX Kit employs a hot -start DNA polymerase, for high PCR specificity and sensitivity. SensiMix SYBR ® Hi -ROX is inactivated and possesses no polymerase activity during the reaction set -up, preventing non -specific amplification including primer -dimer formation.For ease -of -use and added convenience, SensiMix SYBR ® Hi -ROX is provided as a 2x master mix containing all the components necessary for real -time PCR (qPCR), including the SYBR ® Green I dye, dNTPs, stabilizers and ROX for optional use. As a ready -to -use premix, only primers and template need to be added. Kit compatibilityPrimers: the sequence and concentration of primer as well as the amplicon length can be critical for specific amplification, yield and overall efficiency of any qPCR. We strongly recommend taking the following into consideration when designing and running your PCR reaction:• use primer -design software, such as Primer3 or visual OMP TM (/primer3/ and DNA Software, Inc ; / respectively). Primers should have a melting temperature (Tm) of approximately 60 °C• optimal amplicon length should be 50-150 bp• a final primer concentration of 250 nM is suitable for most PCR conditions, however to determine the optimal concentration we recommend a primer titration in the range of 0.1–1 μM• use equimolar primer concentrations• when amplifying from cDNA use gene -specific primers. If possible use intron -spanning primers to avoid amplification from genomic DNATemplate: it is important that the DNA template is suitable for use in PCR in terms of purity and concentration. Also, the template needs to be devoid of any contaminating PCR inhibitors (e.g. EDTA). The recommended amount of template for PCR is dependent upon the type of DNA used. The following should be considered when using genomic DNA and cDNA templates:• Genomic DNA: use up to 1 μg of complex (e.g. eukaryotic) genomic DNA in a single PCR. We recommend using the ISOLATE Genomic II DNA Mini Kit (BIO -52066) for high yield and purity from both prokaryotic and eukaryotic sources• cDNA: the optimal amount of cDNA to use in a single PCR is dependent upon the copy number of the target gene. We suggest using 100 ng cDNA per reaction, however it may be necessary to vary this amount. To perform a two -step RT -PCR, we recommend using the SensiFAST cDNA Synthesis Kit (BIO -65053) for reverse transcription of the purified RNA. For high yield and purity of RNA, use the ISOLATE II RNA Mini Kit (BIO -52072)General considerationsTo help prevent any carry -over DNA contamination we recommend that separate areas be maintained for PCR set -up, PCR amplification and any post -PCR gel analysis. It is essential that any amplified PCR product should not be opened in the PCR set -up area.Website:/sensimixemail:****************************PI -50231 V11__________________________________________________________________________________________________________________________LICENSING INFORMATION2) Purchase of this product conveys a licence from Life Technologies to use this SYBR ® containing reagent in an end -user RUO assay.

Email: ********************************MgCl 2: The MgCl 2 concentration in the 1x reaction mix is 3 mM. In the majority of qPCR conditions this is optimal for both the reverse transcriptase and the hot -start DNA polymerase. If necessary, we suggest titrating the MgCl 2 to a maximum of 5mM.PCR controls: It is important to detect the presence of contaminating DNA that may affect the reliability of the data. Always include a no template control (NTC), replacing the template with PCR -grade water. When performing a two -step RT -qPCR, set -up a no RT control as the NTC for the PCR.ProcedureReaction mix composition: Prepare a PCR master mix. The volumes given below are based on a standard 50 μL final reaction mix and can be scaled accordingly.Optional ROX: The SensiMix ™SYBR Hi -ROX Kit is premixed with ROX (5-carboxy -X -rhodamine, succinymidyl ester), so that where necessary, ROX fluorescence can be optionally detected on certain real -time instruments. If your real -time instrument has the capability of using ROX and you wish to use this option, then this option must be selected by the user in the software.Troubleshooting GuideSuggested thermal cycling conditionsThe PCR conditions described below are suitable for the SensiMix ™ SYBR ® Hi -ROX Kit for the majority of amplicons and real -time PCR instruments. However, the cycling conditions can be varied to suit customer or machine -specific protocols. The critical step of the PCR is the 10 minute initial activation at 95 °C. The detection channel on the real -time instrument should be set to (SYBR ®) Green or FAM.*Non -variable parameterOptional analysis:After the reaction has reached completion refer to the instrument instructions for the option of melt -profile analysis.Website:/sensimixemail:****************************Website:/sensimixemail:****************************Troubleshooting Guide (Continued)。

Peripheral venous blood was collected from patients on admission and sent for serum creatinine, NT-proBNP, myocardial injury markers, inflammatory indexes, myocardial inhibitory factors, and myocardial autoimmune antibodies. Analyzed the influencing factors of NT proBNP levels in elderly sepsis patients us⁃ing single and multiple factors. Results Compared with the control group, septic shock percentage, SOFA score, APACHEⅡ score, CK-MB, cTnI, PCT, CRP, IL-1β, TNF-α, β1-AAB, and M2-AA in the observation group were significantly higher, Ccr levels was lower, the difference was statistically significant (P<0.05).

实验操作来自于公开的文献,仅供参考细胞实验细胞系MDA-MB-231, A549, and PC3 cell line方法Cell lines were obtained from American Type Culture Collection and grown in the recommended media at 37°C, 5% CO2 in a humidified incubator. Cells were plated in triplicate 96-well microtiter plates at 1,000 cells per well in culture media. GSK461364Adissolved in DMSO or negative control (0.1% DMSO) were added the following day, and one plate was harvested with 50 μL ofCellTiter-Glo (Promega) for a time 0 (T = 0) measurement. Remaining duplicate cell plates were typically incubated for 72 h. Cells werethen lysed with 50 μL CellTiter-Glo, and chemiluminescent signal was read on the Wallac EnVision 2100 plate reader. All data werenormalized to signal at time of compound addition (T = 0). Curves were analyzed using the XLfit (IDBS Ltd.) curve-fitting tool forMicrosoft Excel to determine the gI50 (concentration of 50% growth inhibition relative to T = 0 and Ymax values), the gI-maximum(concentration giving maximum growth inhibition), and the Ymin (bottom of the four-parameter curve at gI-maximum).浓度0~10 μM处理时间72 h动物实验动物模型mice bearing Colo205 tumor xenograft model配制4% DMA/Cremaphore (50:50), pH 5.6剂量every 2 d (q2dx6, q2dx12) or every 4 d (q4dx3) at nominal dose levels of 25, 50, and 100 mg/kg/dose给药处理i.p.不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)小鼠大鼠兔豚鼠仓鼠狗重量 (kg)0.020.15 1.80.40.0810体表面积 (m)0.0070.0250.150.050.020.5K系数36128520动物 A (mg/kg) = 动物 B (mg/kg) ×动物 B的K系数动物 A的K系数例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的K系数(3),再除以大鼠的K系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
