Hypertension is a risk factor for adverse outcomes in patients with coronavirus disease 2019: a cohort study

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.     

Experimental animal models of pancreatic carcinogenesis and metastasis

Pancreatic cancer is a lethal disease characterized by early metastasis, local invasion, and resistance to conventional therapies. To understand its etiology and eventually make prevention of it possible and effective, appropriate carcinogenesis models will certainly help us understand the effects of environmental and genetic elements on pancreatic carcinogenesis. The development of new treatment strategies to control cancer metastasis is of immediate urgency. Fulfillment of this task relies on our knowledge of the cellular and molecular biology of pancreatic cancer metastasis and the availability of biologically and clinically relevant model systems. Many of the existing pancreatic cancer carcinogenesis and metastasis animal models are described in this review. The advantages and disadvantages of each model and their clinical implications are discussed, and special attention is focused on experimental therapeutic strategies targeting pancreatic cancer metastasis.     

脑前循环系统动脉瘤的外科治疗

本文报告113例脑前循环系统动脉管其中包括颈内动脉后交通动脉瘤75例.前交通动脉瘤17例,大脑中动脉瘤10例,人脑前动脉-胼周动脉瘤3例,颈内动脉-眼动脉瘤2例,颈内动脉海绵窦段动脉瘤1例.多发动脉瘤5例.共118个动脉瘤在显微镜下直视手术,动脉瘤直接夹闭术108例.孤立或包裹术5例:5例多发动脉瘤行同期手术3例,分期手术2例.术中发生动脉瘤破裂18次.Hunt和HessⅠ～Ⅱ级病人中有例行早期手术.全组术后死亡率为7.9%.着重讨论手术时机.术中动脉瘤破裂处理及多发动脉瘤的治疗.     

大肠肿瘤组织中EB病毒的原位杂交检测

目的：探讨EB病毒感染与人大肠癌发生的关系。方法：用原位分子杂交法对130例人大肠癌标本中EB病毒小分子RNA片段进行检测。结果：130例标本中有6例（4.48％）癌组织呈阳性反应，其中4例为男性，4例有明显淋巴细胞浸润。结论：EB病毒感染可能与我国部分大肠腺癌的发生有关，肿瘤细胞间质中大量淋巴细胞浸润可能是EB病毒感染的重要病理学特征。

近几年来，我所党委一班人始终坚持党对单位的政治领导，加强班子建设，振奋精神，团结协作，不断深化人事分配制度改革，大力调动广大干部职工的积极性，有力地推动了全所各项工作快速发展。我们的主要做法是“四讲、四提高”。     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

阿昔洛韦联合胸腺肽抗乙肝病毒疗效观察

本文报道了阿昔洛韦联合胸腺肽对慢性乙型肝炎抗病毒疗效，阿昔洛韦１０ｇ，胸腺肽１６ｍｇ静滴，每日一次，连续治疗２月，共治疗３３例，治疗结束后，治疗组ＨＢｅＡｇ阴转１６例，阴转率５５１７％，ＨＢＶ ＤＮＡ阴转１８例，阴转率５４５４％。对照组ＨＢｅＡｇ阴转率９５２％（２／２５），ＨＢＶ ＤＶＡ阴转率９０９％（１／２５），两组比较有显著性差异（ｐ＜００１），表明阿昔洛韦联合胸腺肽是一种有效、价廉、使用方便的抗乙型肝炎病毒药物。
