急性心肌梗塞患者红细胞磷脂水平测定

本文测定了第１－７天急性心梗塞患者红细胞磷脂主要组分含量。结果表明，急性心肌梗塞患者红细胞膜的神经鞘磷含量较正常人明显增高；磷酯酰胆硷，磷脂酰丝氨酸、磷脂酰乙醇胺含量却较正常人明显降低。这说明急性心肌梗塞患者存在红细胞磷脂代谢紊乱，这时心肌缺血的重可能产生不良影响。     

6种中药制剂治疗急性脑梗死的成本-效果分析

目的：运用药物经济学的方法对在我院应用的6种中药注射液进行成本-效果分析。方法：271例急性脑梗死患者依据药物治疗方案不同分为6组，即血塞通组、舒血宁组、苦碟子组、疏血通组、川芎嗪组、丹红组，分别观察疗效，并运用药物经济学的方法进行成本-效果分析。结果：疏血通组的成本为3 419.90元，总有效率最高（91.84%），6组间增量成本-效果最低。因此疏血通组是较为合理、经济的方案。

Secretory immunoglobulin‐A reactivity following increases in workload intensity using the Defined Intensity Stressor Simulation (DISS)

Previous work suggests that secretory immunoglobulin‐A (S‐IgA) reactivity is inversely related to the perceived demands of the stressor. The Defined Intensity Stressor Simulation (DISS) comprises eight stressor modules, and allows for the manipulation of stress either through increasing the number of modules, or increasing the workload of the modules. The current study assessed the effect of increasing the workload of four modules upon S‐IgA reactivity and perceived demands. Participants (N = 14) attended three sessions on consecutive days where they provided a timed saliva sample immediately before and after 5 min on the DISS at low, medium and high workload. Following each session participants recorded their perceptions of the task with regard to workload and levels of stress and arousal. Perceived workload and stress, but not arousal, increased in accordance with increases in workload, however, differential S‐IgA reactivity was observed. Low workload resulted in a slight increase in S‐IgA secretion; medium workload elicited significant up‐regulation, while down‐regulation of S‐IgA occurred following high workload. As DISS is analogous to a variety of working environments it is suggested that the observed S‐IgA reactivity is indicative of how individuals react to multi‐tasking environments when faced with increases in objective or perceived workload demands. As S‐IgA levels are related to protection from illness, down‐regulation of S‐IgA in those who perceive greater demands may lead to greater vulnerability to ill‐health.

急性胆囊炎腹腔镜手术时机探讨及操作技巧

目的 探讨急性胆囊炎行腹腔镜胆囊切除术的手术时机，并总结操作技巧。方法 回顾性分析2000年6月～2005年6月265例腹腔镜胆囊切除术治疗急性胆囊炎的临床资料。结果 265例中手术成功244例，成功率92．1％。中转开腹21例，其中小于72小时（Ⅰ组），超过72小时（Ⅱ组）的中转率分别为3．1％（4／129），12．5％（17／136）。Ⅰ组与Ⅱ组比较成功率无明显差别（P〉0．05）。全组无死亡病例，也无严重并发症发生。结论 急性胆囊炎行腹腔镜胆囊切除术安全可行，只要无内科禁忌证，应积极开展腹腔镜手术。     

NASOGALLBLADDER DRAINAGE FOR MIRIZZI’S SYNDROME

The authors experienced a case of Mirizzi’s syndrome successfully treated with endoscopic nasogallbladder drainage (ENGBD). The patient was a 63‐year‐old man. He was admitted with abdominal pain and jaundice. Laboratory data indicated leukocytosis and elevation of serum bilirubin level. Abdominal ultrasound showed marked swelling of gallbladder and debris in the gallbladder, therefore, the authors strongly suspected Mirizzi’s syndrome. He had past history of acute myocardial infarction and treated with anticoagulation therapy. Then, the authors couldn’t perform surgical removal or percutaneous transhepatic drainage, and tried endoscopic transpapillary drainage. Endoscopic retrograde cholangiopancreatography revealed smooth stricture in the superior portion of common bile duct and occlusion of the cystic duct, and ENGBD was then performed. After ENGBD, his complaints, laboratory data, swelling of gallbladder and stricture of common bile duct were all remarkably improved.     

SARS死亡病例的实验室检查特点

目的：了解严重急性呼吸综合征(SARS)死亡病例的临床特点，为SARS重症病例的诊断、治疗及预后判断提供帮助。方法：对我院2003年1月至4月底收治的102例确诊非典患者中的5例死亡病例的流行病学及实验室检查资料进行回顾性分析。结果：死亡病例均为男性，平均49岁，从发病到入院平均7．6d，从住院到确诊平均1．2d；从住院到死亡平均14．4d，从发病到死亡平均为22d。死亡病例粒细胞总数和百分比均明显升高，多数患者淋巴细胞计数和百分比降低(4／5)，血红蛋白均呈进行性下降。死亡患者除已见报道的ALT、AST、LDH、CK升高及低钙血症外，GLU均明显高于正常而ALB均明显降低；大多数患者TP、PA等多项生化指标均出现明显下降而脱氧血红蛋白百分率(HHb)明显上升，同时伴有低磷、低镁血症。结论：SARS死亡病例多项实验室指标均会出现明显异常，动态监测这些指标有助于SARS患者的诊断、治疗及预后判断。
