Combined therapy of hypertensive nephropathy with ginkgo leaf extract and dipyridamole injection and antihypertensive drugs: A systematic review and meta-analysis

Background:In recent years, the incidence rate of hypertensive nephropathy has been increasing quickly, which has been a major threat to people''s health. Renin-angiotensin-aldosterone system blockers have certain curative effects. However, there are some patients having serious adverse reactions, and the benefit population is limited, so the treatment of hypertensive renal damage is necessary to have beneficial supplement. More and more clinical studies have shown that ginkgo leaf extract and dipyridamole injection (GDI) combined with antihypertensive drugs has achieved good results in the treatment of hypertensive renal damage. It is supposed to be a supplementary treatment in hypertensive nephropathy.Objectives:To systematically assess the efficacy and safety of GDI combined with antihypertensive drugs on hypertensive renal injury.Methods:Seven databases including PubMed, Cochrane Library, Embase, Wanfang database, China biomedical literature service system (Sino Med), VIP Chinese Sci-tech journal database (VIP), and China national knowledge internet (CNKI) were retrieved to collect randomized controlled trials (RCTs) in the experimental group containing combined therapy of hypertensive nephropathy with GDI and antihypertensive drugs. The retrieval time was from the establishment of database to July 8, 2020. Two researchers independently selected literature, extracted data, and evaluated the risk of bias in the study. The methodological quality was evaluated with Cochrane handbook and meta-analysis was performed with Stata 14.0 software.Results:Eight studies were included in this study which involved 556 patients. The meta-analyses indicated that, compared with using antihypertensive drugs alone, combined treatment of GDI with antihypertensive drugs can decrease 24-hour urinary total protein (weighted mean difference [WMD] –0.61, 95% confidence interval [CI]: –0.82, –0.39; k = 6, P ≤ .001), blood urea nitrogen (WMD –1.27, 95% CI: –2.45, –0.10; k = 6, P = .033, serum creatinine (WMD –29.50, 95% CI: –56.44, –2.56; number of estimates [k] = 6, P = .032).Conclusions:Our meta-analyses showed that GDI combined with antihypertensive drugs can improve the renal function of hypertensive patients with renal injury.     

A Novel New Delhi Metallo-β-Lactamase Variant,NDM-14, Isolated in a Chinese Hospital Possesses Increased Enzymatic Activity against Carbapenems

A novel New Delhi metallo-β-lactamase (NDM) variant, NDM-14, was identified in clinical isolate Acinetobacter lwoffii JN49-1, which was recovered from an intensive care unit patient at a local hospital in China. NDM-14, which differs from other existing enzymes by an amino acid substitution at position 130 (Asp130Gly), possesses enzymatic activity toward carbapenems that is greater than that of NDM-1. Kinetic data indicate that NDM-14 has a higher affinity for imipenem and meropenem.     

Suppression of PRDX4 inhibits cell proliferation and invasion of ectopic endometrial stromal cells in endometriosis

Abstract

Oxidative stress (OS) has been proposed to play a role in the development of EMs. Peroxiredoxins are a family of antioxidant proteins that exhibit peroxidase activity in a thioredoxin-dependent manner, protecting cells against OS. The Western blotting results showed that the relative expression of PRDX4 was significantly increased in ectopic endometria compared with the normal endometria of EMs-free (p?<?.05). The H₂O₂ concentration was also significantly higher in the ectopic endometrium. PRDX4 siRNA was transfected into primary ectopic endometrial stromal cells (EESCs). The viability of the transfected EESCs was measured by CCK-8 assay, and the results showed significantly decreased cell viability. Furthermore, the apoptosis rate and ROS generation in flow cytometry assays were significantly increased after the knockdown of PRDX4 expression (p?<?.05). Scratch assays and transwell assays revealed that decreased expression of PRDX4 mediated by siRNA inhibited EESC migration and invasion. In conclusion, these findings indicate the potential role of PRDX4 in the development of EMs and PRDX4 as a possible therapeutic target for EMs treatment.

目的 探讨小儿弯刀综合征的诊断、外科治疗方法及治疗后的近、中期结果。方法 回顾性分析2010年1月到2017年12月手术治疗的14例弯刀综合征的临床资料。其中,男7例,女7例;年龄(18.23±28.55)个月,范围在23 d至9岁。合并其他心血管畸形10例,中位心8例,右肺发育不良7例,有侧支循环8例,合并肺动脉高压10例。用SPSS 16.0软件的寿命表(Life Table)做出本组患儿术后生存曲线,评估其近、中期生存状况。结果 9例异常肺静脉(scimitar vein,SV)从下腔静脉切下,端-侧吻合于左心房;SV分成2支2例,1例采用2支SV连同部分下腔静脉壁切下,另1例2支SV从下腔静脉从根部切下侧-侧吻合形成单根SV,均吻合于左心房;SV离左心房距离过大3例,2例将SV吻合在右心房右侧壁,再重建心房间隔,1例SV与自体心包卷管道连接再吻合于左心房。其他心血管畸形同期手术矫治。8例有侧支循环,3例心导管检查时被封堵,5例手术时切断缝合。本组14例手术死亡2例(14.29%),另有1例于术后1年2个月因肺炎、呼吸衰竭死亡。本组术后1、3、5年累积生存率分别为86%、73%和73%。术后出院时有1例移植的SV开口狭窄,血流速度为1.9 m/s;有3例随访期间发现移植SV狭窄,血流速度超过1.6 m/s。结论 弯刀综合征可合并其他心血管畸形、中位心、右肺发育不良等。一般将SV与左心房吻合;SV离左心房距离大或多条SV时,可采用个性化办法将SV吻合于左心房。侧支循环心导管检查时可封堵,或术中切断缝合。     

论中医多学科融合的发展路径--从《黄帝内经》谈起

从《黄帝内经》成书与多学科的关系角度出发,探讨中医学学科体系形成的客观原因,认为构建中医理论的经典著作《黄帝内经》的面世有深刻的时代烙印,是当时多学科融合的必然产物。开放包容并不断吸收多学科的学术成果不仅是中医学发展的规律和内在动力,对解决目前中医学的发展困境亦有重要的借鉴意义。当下的中医药科研工作者,应该借助现代科学技术来研究和解读中医,把宝贵的医学经验继承好、发展好、利用好。     

缺血性脑卒中再发相关危险因素分析

目的探讨包括脑白质疏松(LA)在内的相关危险因素与缺血性脑卒中再发的关系。方法连续收集2010年1月至2014年12月在我院保健科、神经内科发病72 h内住院首发急性缺血性卒中患者751例,随访3年,入选患者701例,随访中再发患者124例为再发组;首发缺血性卒中患者577例为未再发组,比较分析两组患者危险因素。结果再发组患者LA程度高于未再发组(Z=-2.307,P=0.021);再发组血糖、血压、血脂控制达标率低于未再发组(均P<0.05)。Spearson相关分析与缺血性卒中再发患者呈正相关的因素为LA(r=0.451,P=0.007)、年龄(r=0.334,P=0.015)、血压(r=0.812,P=0.001)、血糖(r=0.637,P=0.002)、低密度脂蛋白胆固醇(LDL-C)(r=0.674,P=0.000)、总胆固醇(r=0.748,P=0.003)、三酰甘油(r=0.878,P=0.004)、吸烟(r=0.380,P=0.008);与脑卒中再发无明显相关的因素为性别(r=0.032,P=0.115)。二分类Logistics回归与缺血性卒中再发呈正相关因素为年龄(B=0.142,P=0.000)、血压(B=0.135,P=0.000)、LDL-C(B=1.141,P=0.001)、三酰甘油(B=0.367,P=0.036)、血糖(B=0.385,P=0.000);与缺血性卒中再发无相关的因素为LA(B=22.221,P=0.997)、总胆固醇(B=0.081,P=0.867)、吸烟(B=21.434,P=0.995)。结论年龄、高血糖、高血压、三酰甘油是缺血性卒中患者复发的独立危险因素,LA、总胆固醇、吸烟是缺血性卒中复发的混杂因素。进行积极危险因素干预治疗,对预防缺血性卒中复发有重要意义。
