枸杞多糖对S180荷瘤小鼠的免疫抑瘤作用

枸杞多糖（ＬＢＰ）是具有广泛增强免疫功能的一种中药生物活性组分。以Ｓ１８０荷瘤Ｂａｌｂ／ｃ小鼠为模型较为系统地研究了ＬＢＰ对瘤重和脾细胞免疫功能的影响。结果表明，ＬＢＰ剂量依赖性地抑制瘤重。恢复和提高荷瘤鼠脾细胞数及活化Ｔ细胞增殖能力，明显促进ＮＫ活性和ＴＮＦ分泌水平。揭示ＬＢＰ增强荷瘤鼠细胞免疫功能是其抑制肿瘤效应的机制。     

完全性大动脉转位的外科治疗

对３３例完全性大动脉转位施行了手术治疗，其中全腔静脉肺动脉连接３例、改良Ｆｏｎｔａｎ手术２例、Ｍｕｓｔａｒｄ及大动脉调转术各１例，Ｒａｓｔｅｌｉ手术２６例，包括１５例心内隧道和心外管道，１１例心内、外双管道。这２６例心外管道中，除４例采用同种主动脉管道外，其余为经处理的猪肺动脉人工管道。全组手术死亡１０例，晚期死亡１例。结论：完全性大动脉转位病理解剖变异性大，应按不同类型的病理解剖特征选择手术方法     

综合因素与老年人心律失常(附200例病例分析)

通过对200例老年人心律失常的病因分析,明确了老年人心律失常的发生有其形态学基础,再加上疾病综合作用所致。其中缺血性心脏病占首位,再依次为高血压病、肺心病、脑血管病、糖尿病、颈椎病。同时患有两种以上疾病的心律失常发生率明显增高。另外还对心功能及烟酒对心律失常的影响进行了初步探讨,结果显示心功能异常及吸烟与心律失常的发生呈正相关,饮酒与心律失常的发生呈负相关。     

电针改善硬膜外吗啡用于术后镇痛所引起的免疫抑制

为观察硬膜外吗啡和电针对术后患者免疫功能的影响，检测自然杀伤细胞（ＮＫｃｅｌｌ）活性和ＰＨＡ诱导白细胞介素２（ＩＬ－２）水平在单纯胆囊切除术患者术前和术后第１、３、７天的动态变化情况。结果吗啡组ＮＫ活性在术后第１、３、７天抑制，手术组仅在术后第１、３天出现抑制，而抑制率低于同天的吗啡组，电针可拮抗吗啡引起的ＮＫ活性抑制加深状况。在术后第１天，手术组和吗啡组ＩＬ－２水平均下降，吗啡＋电针组无明显变化，术后第７天吗啡＋电针组ＩＬ－２升高接近正常人水平。表明电针能改善硬膜外吗啡引起的免疫抑制，促进术后机体的恢复。硬膜外吗啡结合电针是值得推荐的术后镇痛方法。     

N-乙酰半胱氨酸对鼠肝超急性排斥反应的抑制作用

目的：应用大鼠肝脏灌注模型研究N—乙酰半胱氨酸(NAC)对异种移植超急性排斥反应的抑制作用。方法：SD大鼠24只分为4组，每组6只，分为鼠血灌注组、人血灌注组、N—乙酰半胱氨酸(NAC)治疗鼠血灌注组、N—乙酰半胱氨酸(NAC)治疗人血灌注组。全麻下分离出胆总管、门静脉、肝上下腔静脉并插管，缺血30min后，原位灌注鼠肝2h，灌注过程按每30min收集胆汁，并监测灌注压力和动脉血气，在不同时间取血样检测脂质超氧化(MDA)、氮自由基(NO)、肝功能(Alt、Ast)。结果：异种灌注组，MDA、NO、的升高及Alt、Ast均明显高于对照组，胆汁流量明显减少；NAC的治疗抑制了异种灌注组MDA、NO的升高，Alt、Ast水平也明显低于对照组，胆汁流量明显增加，保护了肝脏功能。结论：自由基可能参与了异种移植的超急性排斥反应，NAC的治疗可部分抑制HAR，并保护大鼠异种移植的肝脏功能。     

山羊急性心肌缺血时恶性心律不齐的发生和...

The coronary collateral circulation of goat is very spare, so myocardiac ischemia model of goat can simulate the patient previously with normal coronary circulation and suddenly developing complete occlusion of coronary arteries. In this study 80 Chengdu goats were used, and the branches of their left coronary artery were ligated. Ventricular tachycardia (VT) developed in 23 goats and ventricular fibrillation (VF) in 39 goats. VT and VF both occurred in the early phase of acute myocardial ischemia, and both had 6 min as the median time of onset. In 71 cases data on the weight of myocardiac ischemic area were collected, in which the weight percentage of ischemic area relating to the ventricles of 34 goats with VF was significantly higher than that of 37 goats without VF (35.4 +/- 2.4% vs 19.5 +/- 1.9%). After coronary ligation, 9 cases directly precipitated into VF which could not be defibrillated. In the remaining 62 cases, the weight percentage of ischemic area of 21 cases with VT was higher than that of 41 cases without VT (32.9 +/- 2.8% vs 20.9 +/- 2.1%). The relationships between the incidence of VT or VF and the weight percentage of ischemic area were fitted with logistic curve. The likelihood of occurrence of VT or VF is increased as the weight percentage of ischemia area goes up.     

环隙气升式反应器在非牛顿流体体系中的应用──反应器特性研究和体积氧传递系数的关联

以羧甲基纤维素钠（ＣＭＣ）水溶液模拟非牛顿型发酵介质，在内径为０．１５ｍ，高为０．９７５ｍ的环隙气升式反应器内，考察了液体流变性质和导流筒结构对气液传质的影响，提出了体积氧传递系数（ＫＬａ）的经验关联式。实验表明：对于较高粘度的假塑性流体，反应器内部采用整体式导流筒结构，将有利于传质和混合，其性能优于采用开窗式导流筒或无导流筒的反应器。     

Partial splenic embolization for hypersplenism concomitant with or after arterial embolization of hepatocellular carcinoma in 30 patients

Purpose To study the value of partial splenic embolization (PSE) for the treatment of hypersplenism in patients undergoing embolization of hepatocellular carcinoma (HCC). Methods Transcatheter hepatic arterial embolization (THAE) combined with PSE was performed in 30 patients with HCC complicating liver cirrhosis, portal hypertension, and hypersplenism. Gelfoam sponge was used as the embolic material for PSE and limited to 100–150 pieces. Results More than 50% of splenic parenchyma was infarcted in 27 patients. Leukopenia and thrombocytopenia were corrected by PSE in 25 of 27 patients with hypersplenism. In 26 patients with esophageal varices, including 5 patients with bleeding, no rebleeding occurred during a 6–17 month follow-up. Hypersplenism was not corrected in 2 of 3 patients whose infarcted splenic parenchyma was less than 50%. No splenic abscesses or other severe complications were observed. Of the 30 patients treated, 19 are still alive after 1 year. Conclusions THAE combined with PSE is a safe and effective measure for patients with HCC.
