Comparison between a new platelet count drop method PL-11, light transmission aggregometry,VerifyNow aspirin system and thromboelastography for monitoring short-term aspirin effects in healthy individuals

Platelet function has been described by many laboratory assays, and PL-11 is a new point-of-care platelet function analyzer based on platelet count drop method, which counts platelet before and after the addition of agonists in the citrated whole blood samples. The present study sought to compare PL-11 with other three major more established assays, light transmission aggregometry (LTA), VerifyNow? aspirin system and thromboelastography (TEG), for monitoring the short-term aspirin responses in healthy individuals. Ten healthy young men took 100?mg/d aspirin for 3-day treatment. Platelet function was measured via PL-11, LTA, VerifyNow and TEG, respectively. The blood samples were collected at baseline, 2 hour, 1 day during the aspirin treatment and 1 day, 5?±?1 days, 8?±?1 days after the aspirin withdrawal. Moreover, 90 additional healthy subjects were recruited to establish a reference range for PL-11. Platelet function of healthy subjects decreased significantly 2 hours after 100?mg/d aspirin intake and began to recover during 4–6 days after the aspirin withdrawal. Correlations between methods were PL-11 vs. LTA (r?=?0.614, p?<?0.01); PL-11 vs. VerifyNow (r?=?0.829, p?<?0.01); PL-11 vs. TEG (r?=?0.697, p?<?0.001). There was no significant bias between PL-11 and LTA at baseline (bias?=?1.94%, p?=?0.804) using Bland-Altman analysis, while the data of PL-11 were significantly higher than LTA (bias?=?24.02%, p?<?0.001) during the aspirin therapy. The reference range for PL-11 in healthy young individuals was from 66.8 to 90.5% (95%CI). When aspirin low-responsiveness was defined as LTA?>?20%, the cut-off values for each method were, respectively: PL-11?>?50%, VerifyNow?>?533 ARU, TEG?>?60.2%. The results of different platelet function assays were uninterchangeable for monitoring aspirin response and correlations among them were also varied. Correlations among PL-11 and other three major assays suggested the ability of PL-11 to assess the treatment effects of aspirin. But a large cohort study is needed to confirm the cut-off value of aspirin response detected by PL-11.

基于网络药理学方法探究补肾活血汤治疗激素性股骨头坏死的作用机制

目的:探讨补肾活血汤治疗激素性股骨头坏死(steroid-induced osteonecrosis of the femoral head,SONFH)的作用机制。方法:通过中医药整合药理学网络计算研究平台(integrative pharmacology-based network computational research platform of Traditional Chinese Medicine,TCMIP)v2.0预测、筛选补肾活血汤组方中14味中药的作用靶标,通过GeneCards、CTD和OMIM数据库查询SONFH的疾病靶点。根据获取的药物靶标和疾病靶点,进一步利用TCMIP v2.0中医药关联网络分析模块构建"药物靶标-疾病靶点"相互作用网络,根据网络拓扑特征值筛选补肾活血汤治疗SONFH的核心作用靶点。利用GO和KEGG数据库,采用富集算法挖掘上述方剂核心作用靶点的生物学功能和通路信息。结果:共获得891个补肾活血汤药物靶标和365个SONFH疾病靶点。经"药物靶标-疾病靶点"相互作用网络分析,最终筛选出31个补肾活血汤治疗SONFH核心靶点,GO功能分析富集出生物过程532条、分子功能29条,KEGG信号通路富集分析出相关通路共12条,主要涉及炎症免疫调节(chemokine signaling pathway,Toll-like receptor signaling pathway,NOD-like receptor signaling pathway,leukocyte transendothelial migration,Complement and coagulation cascades,cytokine-cytokine receptor interaction)、血管新生及血液循环调节(VEGF signaling pathway)、神经系统调节(neuroactive ligand-receptor interaction)和细胞功能调节(apoptosis,regulation of actin cytoskeleton)等方面。结论:结合SONFH的病理机制,排除缺乏特异性的信号通路,我们推测补肾活血汤可能通过调节TLR4/NF-κB和VEGF信号通路发挥补肾壮骨、活血化瘀的功效,这可能是其治疗SONFH的作用机制之一。     

中医药外治疗法治疗混合痔术后并发症临床研究概况

混合痔在其多样化的治疗方案中通过手术治疗是最主要的方法,但因肛管解剖结构和生理功能的特殊性、复杂性,且开放的术口会因排便刺激而损伤局部组织,造成肛门部水肿、疼痛、创面延期愈合等并发症出现,降低患者的生活质量并带来极大的身心痛苦。西医治疗主要是抗感染、止痛、止血等对症处理为主; 而中医治疗是以辨证论治为基础,达到消肿止痛、活血化瘀、抗炎促愈的目的,疗效稳定,尤其是中医外治疗法通过中药熏洗坐浴、灌肠塞肛及针灸敷药等方式直接作用于切口患处,减少胃肠道刺激,发挥多靶点、多环节、多层次的综合调控作用而增加疗效,其成本低、易操作、简便易行,能促进水肿消退、缓解疼痛、减少出血及创面早日愈合。现就混合痔术后并发症的中医药外治疗法进行综述如下。

Effects of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer: A protocol of randomized controlled trial

Background:Gastrointestinal complications and malnutrition are common problems that affect postoperative rehabilitation and survival of patients with esophageal cancer. Evidence has shown that probiotics have a positive effect on improving gastrointestinal complications and nutritional status of patients with esophageal cancer after surgery, but there is a lack of prospective studies on this topic. We designed this prospective randomized controlled trial to evaluate the effects of probiotics on gastrointestinal complications and nutritional status in patients with postoperative esophageal cancer.Methods:This is a prospective, randomized, double-blind, placebo-controlled trial. It was approved by the Clinical Research Ethics Committee of our hospital. 192 patients will be randomly divided into probiotics group and the placebo group in a 1:1 ratio. After operation, probiotics and placebo will be given orally for 8 weeks. The indexes of nutritional status and incidence of digestive tract complications will be recorded and the data will be analyzed by SPSS 18.0 software.Discussion:This study will evaluate the effect of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer. The results of this study will provide clinical basis for the use of probiotics in postoperative treatment of esophageal cancer.Trial registration:OSF Registration number: D DOI 10.17605/OSF.IO/QHW86

新型冠状病毒肺炎(COVID-19)具有强传染性、人群普遍易感性、高病死率等特点;而急性心肌梗死具有发病迅速、最佳救治窗口期短、病情危重等特点,其救治关键在于选择最佳策略以最大限度地提高再灌注效率。目前疫情防控形势严峻,对急性心肌梗死行急诊腔内介入治疗等临床工作也提出了新的要求。为规范救治流程,本研究对心血管医务人员的岗前培训,首诊COVID-19筛查,急性心肌梗死患者病情评估流程,以及急性心肌梗死行急诊介入手术的适应证、手术管理策略等进行了探讨。     

新型冠状病毒肺炎出院患者生活质量及影响因素研究

目的:了解新型冠状病毒肺炎(COVID-19)患者出院后的生活质量及其影响因素,为优化早期干预方案,预防社区生活受限,制定相应社区康复措施提供依据。方法:选择2020年3—4月在武汉华润武钢总医院治愈出院的COVID-19患者57例,于2020年4—5月通过"问卷星"平台采用简明健康状况调查量表(SF-12V2)调查患者的生活质量;采用焦虑自评量表(SAS)调查患者的焦虑状态;采用抑郁自评量表(SDS)调查患者的抑郁状态;采用呼吸困难指数量表(mMRC)调查患者的呼吸困难程度。比较不同特征COVID-19患者生活质量的差异;分析患者生活质量与焦虑、抑郁和呼吸困难程度的相关性及其相关的影响因素。结果:共发放57份调查问卷,剔除重复及无效问卷3份,获得有效问卷54份,问卷有效率达94.74%。(1)COVID-19出院后患者生活质量情况:生理总评分和心理总评分分别为(37.02±12.32)分、(38.46±14.42)分;呼吸困难等级0~3级的分别为3例(5.56%)、45例(83.33%)、5例(9.26%)、1例(1.85%);有19例(35.19%)存在焦虑情绪(SAS≥50分)和抑郁情绪(SDS≥53分)。(2)不同特征COVID-19患者生活质量比较:不同疾病分型的患者在生理总评分方面差异有统计学意义(P<0.05)。(3)生活质量与焦虑、抑郁和呼吸困难程度的相关性分析:Pearson相关分析结果显示,SF-12V2生理总评分与焦虑程度(r=-0.34,P=0.011)和呼吸困难程度(r=-0.39,P=0.003)之间存在负相关性,SF-12V2心理总评分与焦虑程度(r=-0.46,P=0.001)和抑郁程度(r=-0.40,P=0.002)之间存在负相关性。(4)COVID-19患者生活质量的影响因素分析:多元线性回归分析显示,性别(β=8.27)、抑郁程度(β=-0.34)和疾病分型(β=-11.68)是患者SF-12V2生理总评分的重要决定因素(P<0.05);焦虑程度(β=-0.62)是患者SF-12V2心理总评分的重要决定因素(P<0.05)。结论:COVID-19出院患者存在呼吸困难、焦虑抑郁情绪和生活质量下降的问题;性别、疾病分型、抑郁程度和焦虑程度是COVID-19患者生活质量下降的重要因素。COVID-19患者(特别是女性患者和重型患者)出院后要尽早进行抑郁症和焦虑症的筛查和干预,减少患者负性情绪,鼓励患者适当参与康复训练,提高呼吸功能,从而促进生活质量提高。
