科学面对"非典"

一、传染性非典型肺炎的特点和传播途径 传染性非典型肺炎,原来叫非典型肺炎,简称"非典",是指最近发生的,目前病原还没最后确定的一种传染性肺炎.世界卫生组织建议称其为"严重急性呼吸道综合征"(Severe Acute RespiratorySyndromes),简称SARS.典型性肺炎通常是指由肺炎链球菌等常见细菌引起的肺炎.症状比较典型,如发烧、胸痛、咳嗽、咳脓痰等,血常规化验白细胞通常会增高.非典型肺炎,是指由病毒、支原体、衣原体、立克次体和军团菌等引起的肺炎.其临床表现多为干咳,相对典型性肺炎来说症状不典型.     

Antiphospholipid syndrome：a survey of clinical characters in ten cases

Objective: To gain further understanding of the antiphospholipid syndrome(APS) . Methods : Analysing clinical and laboratory data on ten cases of APS. Results: Thrombocytopenia appeared in all cases.Venous thrombi of limbs appeared in five eases and neurological abnormalities in two cases. Renal impairments were found in three cases. One case manifested left renal venous thrombi and the other two cases thrombotic microangiopathy. Budd-Chiari syndrome was found in one case. One of the ten cases was catastrophic APS(CAPS) presented as acute diffuse swelling, cyanosis, pain, ischemia and necrosis in fingers and limbs,recurrem shock, ascites, hepatic and respiratory dysfunction. Anticoagulams and corticosteroids could be effective for dealing with APS. It was critical to treat catastrophic APS with anticoagulants or plasmapheresis as early as possible. Conclusions: APS shows variable manifestations for good prognosis, but catastrophic APS has fatal risk. The main treatment for APS is the use of anticoagulams and immunosuppressives.
