不同时期COPD患者血清DcR3、Survivin表达水平及临床意义

目的 探讨不同时期慢性阻塞性肺疾病(COPD)患者血清诱饵受体3(DcR3)、凋亡抑制蛋白(Survivin)表达水平及临床意义。方法 选取2018年9月—2019年12月本院收治的92名COPD患者为研究对象,其中稳定型COPD 50例,急性加重期COPD 42例;同期本院健康体检者88例为对照组。测定各组研究对象血清DcR3、Survivin水平及肺功能指标。 与对照组[DcR3(106.54±48.35)pg/mL,Survivin(98.85±26.59)pg/mL]比较,稳定期组和急性加重期组血清DcR3[(395.23±123.85)pg/mL,(1 248.81±213.59)pg/mL]、Survivin [(267.54±84.69)pg/mL,(1 233.95±307.26)pg/mL]水平升高;与稳定期组比较,急性加重期组血清DcR3、Survivin水平升高。与对照组比较,稳定期组和急性加重期组FEV1%、FEV1 /FVC、DLCO%水平降低(P<0.001);与稳定期组比较,急性加重期组FEV1%、FEV1 /FVC、DLCO%水平降低(P<0.001)。随着低氧血症严重程度的增加,COPD患者血清DcR3、Survivin水平逐渐增加(P<0.001)。多因素logistics回归分析显示,高水平DcR3、Survivin、IL-12、hs-CRP为COPD病情的危险因素(P<0.001)。DcR3、Survivin与FEV、FEV1 /FVC呈负相关,与IL-12、TNF-α、hs-CRP呈正相关(P<0.001)。 COPD稳定期、急性加重期患者血清DcR3、Survivin表达水平升高,且DcR3、Survivin与COPD病情严重程度呈正相关。     

特发性肺纤维化急性加重期证候与血清生物标志物的相关性研究＊

目的 通过分析特发性肺纤维化急性加重期（AE-IPF）患者证候与血清生物标志物的关系，为中医辨证治疗提供参考。方法 采用观察性研究设计，收集2019年3月至2019年11月三个中心的AE-IPF患者76例，其中痰热壅肺证26例、痰浊阻肺证50例，并纳入健康志愿者10例作为对照。采用ELISA测定患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平，分析与中医证候的相关性。结果 AE-IPF患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平均显著高于健康对照组。血清CCL18、HMGB1、KL-6、MMP-7和SP-D水平在痰热壅肺证和痰浊阻肺证患者间无显著性差异（P＞0.05），而血清SP-A水平存在显著性差异（P＜0.05）。结论 血清SP-A与AE-IPF证候存在一定的相关性，血清SP-A的浓度升高，与痰热壅肺证关系越密切，反之，血清SP-A浓度降低，则与痰浊阻肺证关系越密切。AE-IPF痰热壅肺证患者的预后可能较痰浊阻肺证患者更差。     

中医药治疗特发性肺纤维化的系统评价再评价＊

目的 对中医药治疗特发性肺纤维化（idiopathic pulmonary fibrosis， IPF）的系统评价（SRs）进行再评价。方法 检索知网、中国生物医学数据库、维普、万方、The Cochrane Library、Web of Science、PubMed和EMbase数据库，纳入中医药治疗IPF的SRs，截止2021年5月。使用AMSTAR 2量表进行方法学质量评价，GRADE系统工具进行结局指标证据质量分级。结果 共纳入28篇文献，试验组除辨证论治外，治疗方法集中在活血化瘀、补肺益气等方面，基本符合治疗法则。结果显示中医药治疗IPF可以提高有效率、增加肺功能、提高PaO₂、增加6WMD、缓解临床症状、提高患者的生活质量等。AMSTAR 2量表评价，所纳入SRs均有多项关键条目不达标，整体方法学质量等级不高。采用GRADE工具进行质量分级，一共234个结局指标，无高等证据质量，整体证据等级不高。结论 中医药对比西医治疗IPF有效且不良反应不明显，但RCT研究和系统评价研究方法质量尚有缺陷，完全按照西医评价指标可能会低估真实结果，未来需要更规范的研究及适合中医的评价指标，对中医药研究的安全性方面关注还有待提高。     

儿童结核病的合理用药

结核病是严重危害儿童健康的重要传染性疾病，儿童结核病的发病率影响未来成人结核患者的数量，重视儿童结核病对疾病控制具有重要意义，要控制和消灭结核病，必须十分重视儿童结核病的防治，然而不规范的治疗将直接影响治疗效果，该文就儿童结核病的合理用药进行阐述。     

Tuberculosis during lung cancer treatment-A case series

This study aimed to clarify the characteristics of patients with lung cancer undergoing treatment until the onset of tuberculosis. Between 2005 and 2019, patients who were admitted to Tokyo National Hospital due to tuberculosis during lung cancer treatment were examined retrospectively. There were 42 patients, and detailed medical information was obtained in 39 patients. The median age of the 39 patients were 75 years (range: 47–92 years), of which 33 were males and 36 were Japanese Baby Boomers or older. Regarding risk factors for developing tuberculosis, smoking was noted in 34 cases, oral corticosteroid use in 13, and previous tuberculosis in six. Thirty-seven patients had one risk factor and 19 had two or more risk factors, but diagnosis of latent tuberculosis infection (LTBI) was obtained in only one patients, and none had received LTBI treatment. The first-line treatment for lung cancer was resection in 13 cases, chemoradiotherapy in 6, chemotherapy in 10, radiation therapy in 3, laser therapy in 1, and best supportive care (BSC) alone in 6. At tuberculosis onset, BSC accounted for 17 cases, but other situations were considerably existed such as anticancer medication (12 cases), and observation after lung cancer treatment (10 cases). Tuberculosis occurred in various situations in elderly patients with lung cancer. It is critical to actively evaluate the risk of tuberculosis and consider LTBI screening and treatment.     

Good clinical research practice (GCRP) in pharmacodynamic studies of neuromuscular blocking agents III: The 2023 Geneva revision

The set of guidelines for good clinical research practice in pharmacodynamic studies of neuromuscular blocking agents was developed following an international consensus conference in Copenhagen in 1996 (Viby-Mogensen et al., Acta Anaesthesiol Scand 1996, 40 , 59–74); the guidelines were later revised and updated following the second consensus conference in Stockholm in 2005 (Fuchs-Buder et al., Acta Anaesthesiol Scand 2007, 51 , 789–808). In view of new devices and further development of monitoring technologies that emerged since then, (e.g., electromyography, three-dimensional acceleromyography, kinemyography) as well as novel compounds (e.g., sugammadex) a review and update of these recommendations became necessary. The intent of these revised guidelines is to continue to help clinical researchers to conduct high-quality work and advance the field by enhancing the standards, consistency, and comparability of clinical studies. There is growing awareness of the importance of consensus-based reporting standards in clinical trials and observational studies. Such global initiatives are necessary in order to minimize heterogeneous and inadequate data reporting and to improve clarity and comparability between different studies and study cohorts. Variations in definitions of endpoints or outcome variables can introduce confusion and difficulties in interpretation of data, but more importantly, it may preclude building of an adequate body of evidence to achieve reliable conclusions and recommendations. Clinical research in neuromuscular pharmacology and physiology is no exception.     

儿童哮喘与成人慢性阻塞性肺疾病相关性研究进展

儿童哮喘与慢性阻塞性肺疾病(COPD)是儿童期与成人期常见的存在气流受限的慢性气道疾病。研究发现,儿童哮喘会增加成年期罹患COPD的风险,而肺功能变化是预测COPD患病风险的重要指标。针对哮喘患儿建立长期肺功能监测管理,对于评估其成年后存在不可逆气道阻塞的风险有重要意义。文章综述儿童哮喘与COPD相关的研究进展。
