0843PAGE 1 OF 24LIQUID ASSAYED CHEMISTRY CONTROL PREMIUM PLUS - LEVEL 1 (LIQ CHEM ASY PREMIUM PLUS 1)Cat. No . LAL 4213 Lot No . 153UL Size : 12 x 5 ml Expiry : 2015-02INTENDED USEThis product is intended for in vitro diagnostic use, in the quality control of diagnostic assays. The Liquid Assayed Chemistry Control Premium Plus is for the control of accuracy.DEVICE DESCRIPTIONThe Liquid Assayed Chemistry Control Premium Plus is supplied at 3 levels, level 1, 2 and 3. Target values and ranges are supplied for the analytes listed in the values section at all three levels.SAFETY PRECAUTIONS AND WARNINGSFor in vitro diagnostic use only. Do not pipette by mouth. Exercise the normal precautions required for handling laboratory reagents.Human source material from which this product has been derived has been tested at donor level for the Human Immunodeficiency Virus (HIV 1, HIV 2) antibody, Hepatitis B Surface Antigen (HbsAg), and Hepatitis C Virus (HCV) antibody and found to be NON-REACTIVE. FDA approved methods have been used to conduct these tests.However, since no method can offer complete assurance as to the absence of infectious agents, this material and all patient samples should be handled as though capable of transmitting infectious diseases and disposed of accordingly.Health and Safety Data Sheets are available on request.STORAGE AND STABILITY OPENED: Store refrigerated (+2ºC to + 8ºC). Thawed serum is stable for 7 days at +2ºC to +8ºC, with the followingexceptions: Troponin T is stable for 3 days at +2ºC to +8ºC. Only the required amount of product should be removed. After use, any residual product should NOT BE RETURNED to the original vial.UNOPENED: Store frozen at -20ºC to -70ºC. Stable to expiration date printed on individual vials (see Limitations).LIMITATIONSFor Total Acid Phosphatase, the material should be stabilised by adding 1 drop (25 µl – 30 µl) of 0.7M Acetic acid solution to 1ml of the serum after thawing. After stabilisation, Total Acid Phosphatase is stable for 7 days at +2ºC to +8ºC. Bilirubin in the serum is light sensitive and it is recommended that the serum is stored in the dark.ALT, Total Acid Phosphatase, Alkaline Phosphatase, Total and Direct Bilirubin values may gradually decrease during the products shelf life.Bacterial contamination of the thawed serum will cause reductions in the stability of many components. The control should not be used as a calibration material.PREPARATION1. Allow the frozen control to thaw at room temperature (+15ºC to +25ºC) until completely thawed. Swirl the contents to ensurehomogeneity.2. Refer to the Control section of the individual analyser application.3. Refrigerate any unused material. Prior to reuse, mix contents thoroughly.MATERIALS PROVIDEDLiquid Assayed Chemistry Control Premium Plus - Level 1 12 x 5 mlMATERIALS REQUIRED BUT NOT PROVIDED NoneASSIGNED VALUESEach lot of serum is submitted to a number of external laboratories. Values are assigned from a consensus of results obtained by these laboratories and internal testing conducted at Randox Laboratories Ltd. With each batch, a control range is provided for individual parameters and each parameter method.If an instrument specific value is not available, refer to the Mean of all Instruments section.

Expression, Purification and Crystallization of
Expression, Purification and Crystallization of the Mycobacterium Tuberculosis HSP16.3 Molecular Chaperone Background of Mycobacterium Tuberculosis HSP16.3HSP16.3, a 16.3 kDa protein from Mycobacterium Tuberculosis, was originally identified as a prominent antigen (Kingston et al., 1987). During the stationary phase, HSP16.3 is maximally expressed and becomes a main protein of the latent phase (Yuan et al., 1996). Previous studies showed that HSP16.3 can make the cell structure stable and prevent stationary Mycobacterium Tuberculosis from autolysing (Cunningham et al., 1998). In previous studies, HSP16.3 was found as one of theα-crystallin-related small heat shock proteins (sHSP) with molecular chaperone activity. Experiments in vitro revealed that HSP16.3 can suppress the thermal aggregation of citrate synthase at 39.5˚C, without consumption of A TP (Chang et al., 1996).Now the Mycobacterium Tuberculosis HSP16.3 gene was cloned to the plasmid pSTE-HSP16.3, and transformed to E.Coli.

Crystallization1 The purified HSP16.3 was solvent-exchanged to water and concentrated to 20mg/ml before crystallization trails (Bradford). All the crystallization trials were carried out using the hanging-drop vapor-diffusion method at 291K: drops consisted of2 microlitres of HSP16.3 protein solution plus 2 microlitres of the precipitant. The drops were equilibrated against 0.2 ml precipitant at room temperature. The crystallization conditions were investigated with a PEG4000 Kit.Result and discussionThe purity of the final HSP16.3 was over 95% by SDS-PAGE.

Keap1
非小细胞肺癌(non-small cell lung cancer,NSCLC)发病率占据肺癌的75%~80%。
肿瘤细胞进展快且易扩散转移,临床常采用手术、放化疗等进行治疗,但5年生存率低于60%[1-2]。
氧化应激是由活性氧(ROS)生成量增加所致,ROS积累可诱导肺癌细胞凋亡,清除ROS 可阻止癌细胞凋亡,即肺癌细胞存活依赖于癌细胞自身抗氧化能力[3]。
Kelch样环氧氯丙烷相关蛋白-1 (kelch-like epichlorohydrin-associated protein-1,Keap1)/核因子E2相关因子2(nuclear factor E2related factor 2,Nrf2)信号通路在癌症中发挥重要调控作用,氧化应激可激活Keap1,促使Keap1-Nrf2复合物裂解,Nrf2转移至细胞核内,可激活下游靶基因表达,参与肺癌发生发展过程[4]。
Nrf2可维持氧化还原稳态,ROS侵袭细胞时,Nrf2可进入细胞核,结合抗氧化反应元件(ARE)转录编码各种抗氧化蛋白、代谢酶基因,抑制氧化应激反应[5-6]。
目前氧化应激、Keap1/Nrf2信号通路在NSCLC发生过程中的机制尚未明确。
基于此,本研究尝试分析Keap1/Nrf2信号通路与临床病理参数、氧化应激指标的相关性,探讨其在NSCLC氧化应激机制中的作用,为临床研制新药提供参考依据。

针剂中先锋必含量的测定
针剂中先锋必含量的测定在酸性介质中,先锋必可以阻抑过硫酸钾氧化荧光桃红的荧光淬灭反应,而且先锋必的含量与荧光强度的变化在 1.0×10-6~1.3×10-5g·mL-1内呈线性关系(R=0.9950),检出限为7.0×10-8g·mL-1。
该法简便、可靠,可用于药物制剂中先锋必含量的测定。
标签:先锋必荧光桃红阻抑先锋必(CRO)是常见的第三代头孢菌素类抗生素药物。
其测定方法药典采用高效液相色谱法[1],已报道的还有分光光度法[2],化学发光法[3],电化学分析法[4]等。
在酸性介质中,利用先锋必可以阻抑过硫酸钾氧化荧光桃红褪色的现象,建立了该方法。
1 实验部分1.1 主要仪器及试剂BS210S电子天平;PHS-P1型酸度计(上海分析仪器厂);HH-4数显恒温水浴锅;970CRT荧光分光光度计(上海精密科学仪器公司)。
荧光桃红:5×10-5mol·L-1;K2S2O8溶液:0.02mol·L-1;邻苯二甲酸氢钾-盐酸(KHP-HCl)pH=3.6;先锋必(CRO)(0.0100g·mL-1);所用试剂均为分析纯,水为二次蒸馏水。
1.2 实验方法依次加5×10-5mol·L-1的荧光桃红1.5mL,KHP-HCl2.0mL,0.02mol·L-1K2S2O81.0mL于10mL试管中,再加入适量先锋必,定容至刻度于65℃恒温水浴中加热20 min后取出且冷却至室温。
然后在970CRT荧光计上(λex=470 nm,λem=556 nm)测定其荧光强度(F),以空白溶液的荧光强度为F0,计算ΔF=F-F0。
2 结果与讨论2.1 激发和发射光谱荧光桃红在光照下显示强烈的红色荧光,当被K2S2O8氧化后,荧光强度大大降低,甚至消失。
对体系中不同溶液的荧光光谱进行扫描,如图1所示。
结果发现体系的最佳λex=470nm和λem=556 nm没有位移,而峰高却有很大改变。

高效液相色谱法测定中国健康志愿者血清中坎地沙坦及坎地沙坦西酯片的人体药动学周玲洁;戴维;顾丽华;王以俭;黄仲义;梁建英【期刊名称】《复旦学报(医学版)》【年(卷),期】2008(35)4【摘要】目的建立高效液相色谱-荧光检测法测定人血清中坎地沙坦的方法,考察坎地沙坦西酯片在中国健康志愿者体内的药动学参数.方法以萘普生为内标,按内标法定量.血清样品经盐酸酸化后,加入甲基叔丁基醚萃取,离心分离,取上清液置于已加入1,3-丙二醇的离心管,吹干后用流动相溶解进样.色谱柱:YMC ODS柱 (250 mm×4.6 mm,5 μm),柱温:30℃;流动相:10 mmol/L磷酸二氢钾溶液(磷酸调pH 到3.0) ∶ 乙腈=60 ∶ 40,流速:1.0 mL/min.荧光检测波长:λex 270 nm,λem 390 nm.用该方法测定20名健康志愿者口服坎地沙坦西酯片8 mg后血清中的药物浓度,进行药动学分析.结果坎地沙坦和萘普生的保留时间分别为10.4 min和16.5 min;坎地沙坦的线性范围是1.01~202 μg/L;日内、日间RSD小于10.39%;方法回收率在94.05%~112.80%范围内.结论此方法适合人体药动学的血样分析,结果准确可靠.【总页数】4页(P552-555)【作者】周玲洁;戴维;顾丽华;王以俭;黄仲义;梁建英【作者单位】复旦大学药学院药物分析教研室,上海,200032;复旦大学药学院药物分析教研室,上海,200032;复旦大学药学院药物分析教研室,上海,200032;复旦大学药学院药物分析教研室,上海,200032;上海市静安区中心医院临床药学与临床药理科,上海,200040;复旦大学药学院药物分析教研室,上海,200032【正文语种】中文【中图分类】R969.1【相关文献】1.坎地沙坦西酯片对老年原发性高血压患者谷峰比值及血压变异性的影响 [J], 罗梅;李霞;罗荔;窦媛媛2.与氯少坦对照评价坎地沙坦西酯治疗轻中度高血压的疗效和安全性 [J], 常玲;孙伟娜;刘红军;王伟3.坎地沙坦西酯片人体药动学和与必洛斯片的生物等效性及坎地沙坦吸收机制的研究 [J], 于万水;胡广云4.坎地沙坦与阿利沙坦酯在原发性高血压患者治疗中的应用效果比较 [J], 吴艳婷5.硝苯地平控释片和坎地沙坦低剂量联合治疗原发性高血压:NICE联合(硝苯地平和坎地沙坦联合)研究 [J], Hasebe N.;Kikuchi K.;杜媛因版权原因,仅展示原文概要,查看原文内容请购买。
