A new method of thoracoscopic sympathectomy in hyperhidrosis palmaris

Summary Although hyperhidrosis palmaris is a benign condition, it may cause considerable psychological, social, and occupational disturbances. There are many conservative measures used to treat hyperhidrosis, but surgical sympathectomy is the only permanent cure. Of the various surgical approaches to the upper thoracic sympathetic ganglia, one must select the approach that combines good functional results and a satisfactory cosmetic outcome with only minor complications. Twenty-one patients (10 men and 11 women) with hyperhidrosis palmaris underwent synchronous bilateral T2 sympathectomy between 1 October 1989 and 30 April 1990. These patients underwent a new method of thoracoscopic sympathectomy without preoperative pneumothorax. All were relieved of excessive sweating in their upper extremities immediately after the operation. In addition, the technique led to significant savings in operation and hospitalization time. We recommend thoracoscopic sympathectomy as the best approach for sympathectomy in cases of hyperhidrosis palmaris.     

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。     

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.     

The effect of the selective PAF antagonist CIS-19 on PAF- and antigen-induced bronchoconstriction, microvascular leakage and bronchial hyperreactivity in guinea-pigs

We investigated the effects of a novel platelet-activating factor (PAF) receptor antagonist, CIS-19 [cis-2-(3, 4-dimethoxyphenyl)-6-isopropoxy-7-methoxy-1-(N-methylformamido)-1, 2, 3, 4-tetrahydronaphthalene], on PAF-, histamine-, substance P- and antigen-induced bronchoconstriction and microvascular leakage, as well as PAF- and antigen-induced bronchial hyperreactivity to methacholine in urethane-anesthetized guinea-pigs. Administration of CIS-19 (0.5–5 mg/kg, i.v.) inhibited the increase in lung resistance induced by PAF (30 ng/kg, i.v.) in a dose-dependent manner, but failed to inhibit the increase induced by histamine (30 μg/kg, i.v.) or substance P (6.5 μg/kg, i.v.). CIS-19 (5 mg/kg, i.v.) did not inhibit the increase in lung resistance induced by ovalbumin (2 mg/kg, i.v.) in actively sensitized guinea-pigs. PAF (30 ng/kg, i.v.)-induced microvascular leakage, measured by the extravasation of Evans blue dye, was dose-dependently inhibited by CIS-19 (0.5–5 mg/kg, i.v.) in the trachea, main bronchi and intrapulmonary airways, but it did not affect histamine (30 μg/kg, i.v.)- or substance P (6.5 μg/kg, i.v.)-induced microvascular leakage at all airway levels. CIS-19 (2.5 and 5 mg/kg) did not affect ovalbumin (2 mg/kg, i.v.)-induced microvascular leakage in all airway levels in actively sensitized guinea-pigs. CIS-19 (2.5 and 5 mg/kg, i.v.) significantly inhibited PAF-induced enhancement of the bronchial response to methacholine, but had no effect on ovalbumin (0.05 mg/kg, i.v.)-induced bronchial hyperreactivity in actively sensitized guinea-pigs. It is concluded that CIS-19 is a potent PAF receptor antagonist which inhibits PAF- but not antigen-induced bronchoconstriction, microvascular leakage and bronchial hyperreactivity. These results suggest that PAF plays little or no role in early airway responses following antigen challenge. Received: 29 April 1996 / Accepted: 10 October 1996     

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.
