A SLAP lesion associated with calcific tendinitis of the long head of the biceps brachii at its origin

Calcific tendinitis is a common condition with characteristic clinical and radiological findings. Although we do not know which condition initiated the pathologic cascade, we present a rare case of calcific tendinitis of the long head of the biceps brachii at its origin, associated with a SLAP lesion. The calcium deposit was removed and the SLAP lesion was repaired with a suture anchor arthroscopically.     

江汉平原鼠间流行性出血热感染研究

为了解湖北省江汉平原流行性出血热（ＥＨＦ）疫区鼠间感染状况，采用挖洞法捕鼠，鉴定鼠种、性别和年龄，检查有无皮肤破伤，检测ＥＨＦＶ抗原抗体。结果，黑线姬鼠和褐家鼠占所捕鼠的６９．７％和２３．６％，其ＥＨＦＶ感染率分别为２１．８％和３０．９％。鼠间ＥＨＦＶ感染，成年鼠显著高于亚成年鼠和幼年鼠，感染率分别为４０．８％、１７．０％和１２．４％；皮肤破伤鼠感染率４５．９％，显著高于非皮肤破伤鼠的１３．９％。感染鼠以窝为单位具有明显的窝聚集性，而感染鼠窝在地理空间上则随机分布。感染鼠血清分型，黑线姬鼠以野鼠型为主，少数为未定型；褐家鼠以家鼠型为主，亦有少数未定型。这表明，江汉平原ＥＨＦ疫区是以黑线姬鼠和褐家鼠为主要宿主动物的家野混合型疫区；年龄、皮肤破伤和密切接触是该疫区鼠间ＥＨＦＶ传播的重要因素。     

颊鳞状细胞癌组织中血管内皮生长因子的表达

目的 :研究颊鳞状细胞癌 (颊癌 )组织中血管内皮生长因子 (VEGF)表达与颊癌细胞生长、转移及预后的关系。方法 :用免疫组织化学法对 37例颊癌标本进行染色 ,观察VEGF的阳性表达率 ,并结合病理和随访资料作统计分析。结果 :37例颊癌组织中VEGF的总阳性表达率为 91 .89% ,有淋巴结转移者VEGF强阳性占 69.2 3 % ,无淋巴结转移者VEGF强阳性占 33 .33 % (χ2 =6 .48,P <0 .0 1 ) ;VEGF和肿瘤浸润深度密切相关 (r =4.54 ,P <0 .0 1 ) ;5a生存组VEGF阳性率低于 5a内死亡组 (χ2 =3 .90 ,P <0 .0 5) ;COX分析结果表明VEGF可作为独立的预后判断指标 (风险比 =2 .90 ,χ2 =7.95 ,P <0 .0 1 )。结论 :VEGF在颊癌生长转移中发挥重要作用 ,可以作为颊癌预后的指标     

城乡家鼠型出血热危险因素研究

对城市60例和农村54例家鼠型出血热病例作1:1配对病例对照研究。经单因素配对分析和多元 Logistic 模型拟合,表明城区居民罹患本病的高危因素是接触鼠及其污染衣物、沟田边坐卧、家里或工作场所鼠患和蚤叮咬;而农村居民的高危因素则是手足皮肤破伤、接触家鸡、沟田边坐卧和吃鼠污染食物.提示城乡居民感染本病病毒的途径有所不同,在预防工作中应予注意.     

Use of an autovenous transplant, polytetrafluoroethylene prosthesis and human umbilical vein bioprosthesis for creating an arteriovenous fistula for programmed hemodialysis

The work presents an experience with 84 operations of making nonstandard arteriovenous fistulas in 75 patients using autovenous transplants, polytetrafluorethylene prosthesis and home bioprostheses from human umbilical veins made at plant "Sever". Results of the operations were followed-up during 3 years. It was shown that arteriovenous fistulas made of plastic materials generally have a higher level of complications and shorter terms of functioning as compared with ordinary fistulas. Nevertheless, using nonstandard fistulas is justified in a certain category of patients.

Development of methods to analyse transcranial Doppler ultrasound signals recorded in microgravity

During space flights, several clinical syndromes may be the result of changes in cerebral circulation. The purpose of the paper is to describe the development and initial evaluation of a system for recording, processing and displaying transcranial Doppler ultrasound (TCD) waveforms from the middle cerebral artery (MCA) in microgravity. Volunteers were repeatedly subjected to 15–20 s intervals of microgravity (‘near zero gravity’) during flights on the KC-135 military aircraft. Continuous TCD recordings from the MCA were stored on magnetic tape. The paper describes the system that was developed to digitise the Doppler ultrasound data and markers that corresponded to the various levels of microgravity, obtain the maximum and mean Doppler waveforms, identify the waveforms and quantify them. The results demonstrate the feasibility of making TCD recordings in a microgravity environment and illustrate excellent performance of the system and its ease of operation. Quantitative waveform analysis of the recordings from the first subject studied in the supine position showed statistically significant changes in MCA velocity waveforms during microgravity.     

Modulation of IgG effector functions by a monovalent fragment of staphylococcal protein A

The monovalent V-1 fragment of protein A (fSpA) with a mol. wt of 13,000 obtained from an u.v. mutant of Staphylococcus aureus Cowan I strain was proved to be able to modulate significantly some of the effector functions of IgG, such as complement fixation, catabolism, attachment to Fc receptors and antibody-dependent cell-mediated cytotoxicity. Moreover fSpA-like protein A obtained from the A676 strain is mitogenic and enhances NK activity of human peripheral lymphocytes. The efficiency of fSpA was found to be lower than that of protein A with regard to its ability to inhibit complement fixation, EA rosette formation and antibody-dependent cell-mediated cytotoxicity. Both protein A and fSpA had the same efficiency in activation of the complement system after reaction with human or guinea pig IgG, and in increasing the IgG catabolism. Unlike fSpA the monovalent B fragment of protein A (with mol. wt of 7000) was not able to inhibit EA rosette formation and antibody-dependent cell-mediated cytotoxicity. The results recommend fSpA, substituting for protein A, as a molecular probe for the investigation of IgG antibody and lymphocyte effector functions.     

Safety and efficacy of oral nemonoxacin versus levofloxacin in treatment of community-acquired pneumonia: A phase 3, multicenter,randomized, double-blind,double-dummy,active-controlled,non-inferiority trial

Background/Purpose

Nemonoxacin is a novel nonfluorinated quinolone with excellent in vitro activity against most pathogens in community-acquired pneumonia (CAP), especially Gram-positive isolates. The purpose of this study was to assess the efficacy and safety of nemonoxacin compared with levofloxacin in patients with CAP.
