机械通气临床应用指南(中华重症医学分会2024)
机械通气临床应用指南中华医学会重症医学分会(2024年)引言重症医学是探讨危重病发生发展的规律,对危重病进行预防和治疗的临床学科。
器官功能支持是重症医学临床实践的重要内容之一。
机械通气从仅作为肺脏通气功能的支持治疗起先,经过多年来医学理论的发展及呼吸机技术的进步,已经成为涉及气体交换、呼吸做功、肺损伤、胸腔内器官压力及容积环境、循环功能等,可产生多方面影响的重要干预措施,并主要通过提高氧输送、肺脏爱护、改善内环境等途径成为治疗多器官功能不全综合征的重要治疗手段。
机械通气不仅可以依据是否建立人工气道分为“有创”或“无创”,因为呼吸机具有的不同呼吸模式而使通气有众多的选择,不同的疾病对机械通气提出了具有特异性的要求,医学理论的发展及循证医学数据的增加使对呼吸机的临床应用更加趋于有明确的针对性和规范性。
在这种条件下,不难看出,对危重病人的机械通气制定规范有明确的必要性。
同时,多年临床工作的积累和多中心临床探讨证据为机械通气指南的制定供应了越来越充分的条件。
中华医学会重症医学分会以循证医学的证据为基础,采纳国际通用的方法,经过广泛征求看法和建议,反复仔细探讨,达成关于机械通气临床应用方面的共识,以期对危重病人的机械通气的临床应用进行规范。
重症医学分会今后还将依据医学证据的发展及新的共识对机械通气临床应用指南进行更新。

碱基切除修复抑制剂甲氧胺联合β-榄香烯治疗恶性脑胶质瘤的实验研究
序言β-榄香烯属国家二类非细胞毒性抗肿瘤新药,临床研究证实其对包括脑胶质瘤在内的多种肿瘤疗效确切,且无其他传统化疗药常有的骨髓抑制、肝肾功能损害等毒副作用。
但目前临床应用的榄香烯乳注射液因其存在静脉炎发生率很高、剂型性质不稳定等缺点,其进一步的应用受到了较大的限制。
碱基切除修复抑制剂甲氧胺(Methoxyamine),可通过裂解核酸内切酶破坏DNA碱基切除修复过程,从而抑制肿瘤细胞对损伤作用的修复反应。
据此,可认为抑制DNA 碱基切除修复可能是增强肿瘤细胞化疗敏感性的潜在靶点,目前多项实验报道也已证实了甲氧胺可增强烷化剂和放疗的抗肿瘤效果。
近年来,通过纳米技术构建的纳米脂质体在提高药物溶解度、增加药物稳定性、降低药物副作用、缓控释给药等方面较普通的脂质体有了显著的提高。
研究表明,纳米脂质体对正常细胞和组织无损伤作用,并可长时间吸附于靶细胞周围,因此使药物能充分向靶组织渗透,也可以通过静电吸附效应与细胞膜接触而融合而进入细胞内。
因此将药物包封于纳米脂质体被认为可以改变被包封药物的体内分布,提高药物治疗指数,降低药物毒性。
基于增强β-榄香烯的疗效,减少毒副作用的目的,本课题研究内容分两部分:(一)联合碱基切除修复抑制剂甲氧胺,探讨是否在体内外抗瘤活性上具有协同作用,以期减少榄香烯用量,降低毒副反应,为其在临床的应用提供实验和理论依据。
(二)、利用纳米脂质体技术构建新型的β-榄香烯-纳米脂质体药物传递系统,初步探讨其体外抗瘤活性。
II碱基切除修复抑制剂甲氧胺联合β-榄香烯治疗恶性脑胶质瘤的实验研究中文摘要胶质瘤是成人神经系统最常见的原发性肿瘤,手术全切除率很低,复发率高,当前多种治疗效果仍不理想。
榄香烯属国家二类非细胞毒性抗肿瘤新药,临床研究发现其对多种肿瘤疗效确切,而且还具有提高和改善机体免疫功能,与放化疗协同作用等独特效果。
但是肿瘤细胞具有强大的DNA损伤修复机制,会对化疗药物产生抗性。
因此抑制这种内在的DNA修复过程,如碱基切除修复抑制剂甲氧胺的联合应用有利于提高化疗药物的抗瘤效果。
血清生物标志物在缺血缺氧性脑病新生儿中的研究进展
血清生物标志物在缺血缺氧性脑病新生儿中的研究进展兰雪,崔艳芳,陈国萍,于嘉,肇颖新(哈尔滨医科大学附属第一医院新生儿科,黑龙江哈尔滨150001)摘要:治疗性低温疗法作为低氧缺血性脑病(hypoxic ischemic encephalopathy,HIE)治疗标准的广泛引入,给临床医生带来了越来越大的压力,要求他们对发生的低氧损伤(hypoxic injury,H I)的程度和随之而来的脑病的严重程度做出早期和准确的评估。
然而,目前还没有任何一种基于血液的标志物足以检测HI或预测预后。
许多炎症蛋白、神经元特异性蛋白和MicroRNA表达可预测HIE病情变化,这些变化在出生的几小时至几天内迅速演变。
将临床数据与生化检测结果相结合是目前改善新生儿HIE的检测和预测结局的最可能途径。
本文总结了目前对HIE血清生物标志物的研究,显示了其预测HIE预后的潜力。

咖啡酸片---肿瘤CIT的应用
中华肿瘤杂志,2018,40(9)Cancer Res 2007; 67: (10). May 15, 2007
巨核细胞凋亡是CIT发生的关键因素
CIT主要是化疗药物对巨核系细胞产生抑制作用。研究显示,化疗药物对于巨核细胞的前体作用最强,对于干细胞和成熟巨核细胞作用相对较弱。
咖啡酸口服半衰期近1小时。主要在肝脏和血浆中代谢,主要生成甲基化、氧化、缩合类的代谢产物。
口服给药,以尿排泄为主,少部分经粪和胆汁排泄。24小时内尿排出97.8%,尿、粪总排量为口服药量的99.5%。

依达拉奉右莰醇通过铁死亡-脂质过氧化通路对脑出血大鼠神经保护的作用机制
实验研究依达拉奉右莰醇通过铁死亡-脂质过氧化通路对脑出血大鼠神经保护的作用机制毛权西,李作孝△摘要:目的探讨依达拉奉右莰醇对脑出血大鼠的神经保护作用及血肿周围脑组织脂质过氧化的影响。
方法将128只SD大鼠随机分为假手术组、脑出血组、依达拉奉组和依达拉奉右莰醇组,每组32只。
除假手术组外,其余组大鼠构建急性脑出血模型,依达拉奉组、依达拉奉右莰醇组于造模后分别腹腔注射依达拉奉6mg/kg、依达拉奉右莰醇7.5mg/kg,每12h注射1次,假手术组和脑出血组腹腔注射等量生理盐水。
术后1d、3d、7d和14d按Garcia评分标准进行神经功能评分,HE染色观察血肿周围脑组织病理变化,化学荧光法检测血肿周围脑组织活性氧(ROS)含量,微量酶标法检测血肿周围脑组织还原型谷胱甘肽(GSH)含量,蛋白免疫印迹法检测血肿周围脑组织谷胱甘肽过氧化物酶4(GPX4)、长链脂酰辅酶A合成酶4(ACSL4)和磷脂胆碱酰基转移酶3(LPCAT3)表达。
结果与假手术组比较,脑出血组大鼠神经功能评分降低,血肿周围脑组织出现大量炎性细胞浸润及神经细胞变性,ROS含量、ACSL4和LPCAT3蛋白表达水平升高,GSH含量、GPX4蛋白表达水平降低(P<0.05);与脑出血组比较,依达拉奉组和依达拉奉右莰醇组大鼠神经功能评分升高,血肿周围脑组织病理损伤明显减轻,ROS含量、ACSL4和LPCAT3蛋白表达水平降低,GSH含量、GPX4蛋白表达水平增加(P<0.05);依达拉奉右莰醇组干预效果优于依达拉奉组(P<0.05);除假手术组外,其余各组均在术后3d时变化最明显,术后7d、14d逐渐恢复(P<0.05)。
结论依达拉奉右莰醇可能通过调节脑出血大鼠神经细胞铁死亡相关蛋白的表达,减少脑组织脂质过氧化,抑制神经细胞铁死亡,从而发挥脑保护作用。

缺血性脑卒中的治疗方法主要包括早期溶栓和保护神经细胞等治疗,然而目前神经保护剂的临床疗效有待考证,大多数神经保护剂仍未得出有益的证据。
新型双靶点复合型神经保护剂依达拉奉右莰醇(ED)可抑制诱导型一氧化氮合酶(iNOS)和肿瘤坏死因子-α(TNF-α)的表达,降低自由基过氧化亚硝基阴离子(ONOO -)水平,从而改善缺血性脑卒中所致的神经损伤症状、功能障碍及活动障碍,本文将对ED 的作用机制及其应用发展做一综述,并对ED 的临床应用进行展望,为后续的用药提供指导。
【关键词】 缺血性脑卒中 自由基清除剂 神经保护剂 依达拉奉右莰醇 Research Progress of Edaravone Dexborneol in the Treatment of Ischemic Stroke/XI Yalin, WANG Linhua, LU Shujun. //Medical Innovation of China, 2024, 21(10): 179-183 [Abstract] Ischemic stroke is a common type of cerebrovascular disease that can lead to advanced cognitive and motor deficits and even death. The treatment of ischemic stroke mainly includes early thrombolysis and neuroprotection. However, the clinical efficacy of neuroprotective agents remains to be verified, and most neuroprotective agents have not yet received useful evidence. Edaravone Dexborneol (ED), a new dual-target neuroprotective agent, can inhibit the expression of inducible nitric oxide synthase (iNOS) and tumor necrosis factor-α(TNF-α), reduce the level of peroxynitrite anion (ONOO -), and improve the symptoms of nerve injury, dysfunction, and activity disorder caused by ischemic stroke. This article will review the mechanism of ED and its application development, and prospect the clinical application of ED, so as to provide guidance for subsequent medication.

Methods After A549 and HCC-1833 cells were treated with a concentration gradient of α-Hederin for 24 and 48 h, the OD 450nm was detected by using CCK8 assays, and the IC 50 was calculated. The A549 and HCC-1833 cells were divided into the blank control and α-Hederin groups in accordance with IC 50 values. Cell proliferation was detected by EdU assays, and cell cycle transformation and cell apoptosis were detected by flow cytometry. Cell mobility was detected by using Transwell and scratch assays. SREBP1 and FASN protein expression levels were detected through Western blot analysis, and cell lipid accumulation was detected via oil red O staining. Results The survival rate of lung cancer cells decreased significantly with the increase of α-Hederin concentration, and the IC 50 values of A549 and HCC-1833 cells at 48 h were 15 and 25 μg/ml, respectively. Compared with the blank control group, cells proliferation and migration were significantly inhibited, cells were blocked in the G 1/S phase, the apoptosis rate increased, and the protein expression and lipid accumulation of SREBP1/FASN significantly reduced after α-Hederin treatment. Conclusion α-Hederin can inhibit the proliferation and migration, G 1/S phase transition and induce the apoptosis of NSCLC cells and hinder the malignant progression of NSCLC by downregulating the expression of SREBP1 and FASN and reducing the accumulation of cell lipids.

维生素D与甲状腺疾病的相关研究进展
维生素D与甲状腺疾病的相关研究进展王君;韩亚玲【摘要】维生素D在人体骨钙代谢平衡中具有重要作用,同时还具有骨骼外作用,它是一种新免疫调节激素,几乎在所有身体组织中均可能产生影响,其中维生素D与甲状腺疾病的关系密切.目前,国内外对Graves病及桥本甲状腺炎的基础及临床研究较为关注,尤其是维生素D缺乏与其患病率有一定的相关性,但其在预防及治疗上的价值仍需进一步研究.同时,虽然维生素D在抗肿瘤治疗中的作用已被认可,但其与甲状腺癌的研究相对较少,未来需要广泛的试验来探索两者之间的关系及作用机制.【期刊名称】《医学综述》【年(卷),期】2018(024)021【总页数】6页(P4245-4249,4255)【关键词】甲状腺疾病;维生素D;25-羟维生素D【作者】王君;韩亚玲【作者单位】保定市第一中心医院内分泌科,河北保定071000;保定市第一中心医院内分泌科,河北保定071000【正文语种】中文【中图分类】R581维生素D属于类固醇化合物,其不仅是人体必需的一种脂溶性维生素,也是一种重要的激素前体。
随着人们对维生素D认识的不断加深,目前发现除维持钙磷平衡和骨骼健康外,维生素D还可以在各种非骨骼疾病中发挥作用,可影响多种细胞的增殖、分化和凋亡等过程,调节免疫系统,是一种新的免疫调节激素。
此外,维生素D可通过调节各种免疫炎性细胞的分化,改变其细胞因子谱,从而影响免疫炎症反应进程。
目前,维生素D在肌肉、心血管、糖尿病、癌症、自身免疫和炎症反应等中的作用逐渐被关注,而其与甲状腺疾病的关系成为研究热点。
在常见的甲状腺疾病中,如Graves病、桥本甲状腺炎(Hashimoto′s thyroiditis, HT)等,在发病过程中常有免疫因素的参与,其生物学作用是通过维生素D受体(vitaminD receptor,VDR)蛋白所介导。
多个研究表明,维生素D缺乏和(或)VDR基因多态性可影响免疫细胞的凋亡,导致甲状腺损伤[1-3]。

结果显示EPS 能显著抑制A431细胞增殖,并呈时间和剂量依赖性,作用96h 的半数抑制浓度I C 50为4125m g/mL,并出现细胞凋亡的形态学改变;彗星电泳结果与对照相比6m g/mL EPS 作用48h 能引起A431细胞DNA 严重损伤;免疫组织化学检测发现6mg /mL EPS 作用72h 能显著上调A431细胞内凋亡相关基因caspa s e 23和bax 的表达,而下调bcl 22的表达。
塞来昔布联合西妥昔单抗对人肠癌HCT-116细胞株生物学行为的影响
塞来昔布联合西妥昔单抗对人肠癌HCT-116细胞株生物学行为的影响林梦心;陈强;陈奕贵;陈慧菁;范芳;施纯玫【摘要】Objective To study the synergistic effect of cyclooxygenase-2 inhibitor Celecoxib and Epidermal growth factor receptor (EGFR) monoclonal antibody Cetuximab on human colorectal cancer cell line HCT-116. Methods K-ras gene of HCT-116 cell line was detected by Sanger sequencing. Cells were divided into control group, Celecoxib group, Cetuximab group and combined group. MTT assay was applied to determine the viability of colorectal cancer cell HCT-116, the cell cycle changes were analyzed by flow cytometry ,and wound healing assay was performed to assess the effects of drugs on cell migration. Results K-ras gene was wild type at 12 codon and mutation at 13 codon in HCT-116 cell line. The celecoxib and cetuximab only inhibited proliferation of HCT-116 in a dose-dependent manner, The combination of celecoxib and cetuximab can decrease the proliferation of HCT-116 with a synergistic action; celecoxib and the combination significantly inhibited the ability of cell migration and induced Go/G1 phase arrested(P<0. 05). Conclusion The proliferation of HCT-116 cell could be inhibited by celecoxib and cetuximab only, both drugs have synergistic effects.%目的观察环氧合酶-2抑制剂塞来昔布联合表皮生长因子受体单克隆抗体西妥昔单抗对人肠癌HCT-116细胞株生物学行为的影响.方法 Sanger测序法检测肠癌HCT-116细胞株的K-ras 基因有无突变;塞来昔布、西妥昔单抗单独或联合作用于HCT-116细胞株,四甲基偶氮唑盐(MTT)法检测细胞增值抑制率,细胞划痕实验检测细胞的迁移能力,流式细胞术检测各组细胞的周期分布.结果HCT-116细胞株K-ras基因12位点为野生型、13位点发生突变;塞来昔布及西妥昔单抗对HCT-116细胞的增殖抑制作用均呈剂量依赖性,两药联用可明显抑制HCT-116细胞的增殖;塞来昔布组和联合用药组均能明显抑制HCT-116细胞的迁移能力,而西妥昔单抗对细胞的迁移能力无明显抑制作用;塞来昔布组及联合用药组使细胞发生明显的G0/G1期阻滞(P<0.05).结论塞来昔布与西妥昔单抗单药可抑制肠癌HCT-116细胞的生长,两者联用具有协同作用.【期刊名称】《福建医科大学学报》【年(卷),期】2012(046)006【总页数】7页(P385-391)【关键词】西妥昔单抗;塞来昔布;药物疗法,联合;HCT-116细胞株;表皮生长因子受体;环氧合酶-2【作者】林梦心;陈强;陈奕贵;陈慧菁;范芳;施纯玫【作者单位】福建医科大学,协和临床医学院,福州,350001;福建医科大学,附属协和医院,肿瘤内科,福州,350001;福建省肿瘤转化医学重点实验室,福州,350001;福建医科大学,教学医院,福建省肿瘤医院,肿瘤内科,福州,350014;福建医科大学,教学医院,福建省肿瘤医院,内科研究室,福州,350014;福建医科大学,教学医院,福建省肿瘤医院,药理研究室,福州,350014;福建省肿瘤转化医学重点实验室,福州,350001;福建医科大学,教学医院,福建省肿瘤医院,肿瘤内科,福州,350014【正文语种】中文【中图分类】R453;R735.3;R329.25;R916.4随着肿瘤分子生物学的发展,结直肠癌的药物治疗进入分子靶向治疗时代。
