大鼠内毒素血症时外周血及肺泡内中性粒细胞死亡方式及呼吸爆发

本研究观察大鼠内毒素血症时肺组织中及外周血多形核中性粒细胞（PMN）凋亡，坏死及功能改变的差异。采用Wistar大鼠20只。腹腔注射LPS（O55B5，5mg/kg)造成内毒素血症，给予LPS后2，4，8，12小时（每组5只动物）取血及支气管肺泡灌洗，密度梯度法分离PMN，用流式细胞仪测定凋亡和坏死比例以及呼吸爆发功能的改变，同时采用5只大鼠作为正常对照。结果显示，内毒素血症时外周血和支气管肺泡灌洗液中PMN凋亡细胞比例相似。但与对照相比，外周血PMN坏死比例明显增加，呼吸爆发能力明显受抑，而支气管肺泡灌洗液PMN坏死比例显减少，呼吸爆发能力显增强。结论：在内毒素血症时，扣押于肺组织中的PMN在凋亡和坏死上表现出与比例显减少，呼吸爆发能力显增强，结论：在内毒素血症时，扣押于肺组织中的PMN在凋亡和坏死上表现出与外周血PMN不同的改变，其结果是组织中PMN存活增加，并持续处于活化状态，这与PMN造成组织损伤有关。

目的 观察湿热痹颗粒的镇痛抗炎作用.方法 采用小鼠醋酸扭体实验来观察湿热痹颗粒的镇痛作用;采用小鼠毛细血管通透性实验及二甲苯致小鼠耳廓肿胀实验观察湿热痹颗粒的抗炎作用;采用Mtb免疫SD大鼠诱导类风湿关节炎模型,通过定期测定大鼠外周血白细胞数、足爪肿胀度并评定炎症积分,观察湿热痹颗粒对模型大鼠关节炎症的抑制作用.结果 湿热痹颗粒高、低剂量组均能明显减少醋酸刺激所致的小鼠扭体反应次数(P<0.01);抑制醋酸所致的小鼠腹腔毛细血管通透性增高及二甲苯所引起的耳廓肿胀(P<0.05);显著减轻类风湿关节炎模型大鼠足爪肿胀程度、降低外周血白细胞数目及关节炎症积分(P<0.05或P<0.01).结论 湿热痹颗粒具有良好的镇痛抗炎作用,且以高剂量组为佳.     

老年人血清胆红素水平与冠状动脉病变程度的关系

目的观察老年人血清胆红素与冠状动脉病变的关系。方法经冠状动脉造影确诊的冠心病患者80例,其中冠状动脉轻度狭窄组15例,中度狭窄组32例,重度狭窄组33例;另外选取冠状动脉造影正常者40例做对照。采用重氮苯磺酸法测定血清胆红素水平,并对胆红素与各因素进行直线相关分析。结果冠心病组血清胆红素水平明显低于正常对照组,血清胆红素水平与冠状动脉病变程度成显著负相关关系(r=-0.26,P<0.05)。结论冠心病患者血清胆红素水平较正常人明显降低。低血清胆红素可能是冠心病的一种危险因素。血清胆红素水平与冠状动脉狭窄程度有明显相关性。

Inguinal hernia repair in Hospital Authority hospitals: The role of laparoscopic hernioplasty

Objective: Two major changes have occurred in inguinal hernia repair during the last two decades: (i) the use of tension‐free mesh repair; and (ii) the application of laparoscopic technique for repair. The aims of the present study were to study: (i) how inguinal hernia repair was carried out; and (ii) the outcome of inguinal hernia repair in Hospital Authority (HA) hospitals. Methodology: This was a retrospective analysis on 8311 elective inguinal hernia repairs performed in 16 HA hospitals from January 2001 to December 2003. The mean age was 63.9 ± 14.2 years, and the male to female ratio was 22.0 : 1.0. Among these, 869 (10.5%) repairs were performed with the laparoscopic approach and 7442 (89.5%) repairs with the open approach. The proportion of laparoscopic hernia repair increased from 8.7% to 12.6%. Results: For open repair, 39% of cases were carried out with regional anaesthesia, 32% with general anaesthesia and 29% with local anaesthesia (LA). Furthermore, mesh repair was used in 88% of the patients. For laparosocpic repair, 98.4% of cases were carried out under general anaesthesia, and all patients had mesh repair using the totally extraperitoneal approach. A significantly higher proportion of bilateral repair and recurrent hernia repair was performed with the laparoscopic approach (P = 0.000). For primary unilateral repair, there was no significant difference in the postoperative length of stay (LOS) and the total LOS between the laparoscopic and the open surgery groups. No difference in LOS was found in recurrent hernia repair between the two groups. With respect to bilateral repair, both the preoperative LOS (P = 0.036) and total LOS (P = 0.039) were shorter in the laparoscopic group. Furthermore, a significantly higher proportion of day‐surgery patients was observed in the laparoscopic group than the open surgery group (21.3%vs 16.9%, P = 0.001). Nevertheless, when only the results of 2003 were analyzed, the postoperative LOS (P = 0.000) and total LOS (P = 0.000) were significantly shorter in the laparoscopic group than the open surgery group. The LOS parameters were significantly shorter in the open surgery LA subgroup compared with the non‐LA subgroup (P = 0.000), and they were not different from those in the laparoscopic group. Conclusions: The open mesh repair is the predominant approach for inguinal hernia repair in HA hospitals. The originally described local anaesthetic approach was under utilized, although it resulted in good outcome. The use of laparoscopic hernia repair is increasing and a learning curve was recently observed with improved outcome.
