动脉灌注灭活再植治疗骨肉瘤的体会

本组１２例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法，术后２年存活率平均为７５％，１例因经验不足致局部复发，仅占８．３％，表明在化疗保障下，采用此种方法即能保肢，又能获得与截肢治疗相同的手术效果，优于单纯行灭活再植术后中方法。     

Role of granulocyte colony-stimulating factor as adjunct therapy for septicemia in children with acute leukemia

The granulocyte colony-stimulating factor (G-CSF) has been shown to accelerate recovery from severe neutropenia and to decrease the incidence of documented infections after intensive chemotherapy in cancer patients. However, the routine prophylactic use of G-CSF is expensive. This study was conducted to determine the role of G-CSF as adjunct therapy for septicemia following neutropenia caused by chemotherapy in children with acute leukemia. Fifty consecutive episodes of septicemia were studied involving 34 episodes of Gram-negative, 7 episodes of Gram-positive, 5 episodes of polymicrobial bacterial septicemia, one episode of fungemia, and 3 episodes of disseminated fungal infection. In the first 25 episodes, G-CSF was not used (group A). For the next 16 episodes, G-CSF 200 μg per square meter per day subcutaneously was given immediately after the septicemia was documented until the absolute neutrophil count was maintained at more than 1,500 per cubic millimeter (group B). Thereafter, G-CSF at the same dose as that of group B was prophylactically used in all the children who received high-dose cytosine arablnc-side-containing regimens. Nine episodes of septicemia occurred (group C). The incidences of mortality per episode of septicemia in groups A, B, and C were 12.0% (3/25), 12.5% (2/16) and 0% (0/9), respectively. Statistically, there was no difference between the three groups overall and in pair-wise comparisons (all P > 0.5). The durations of G-CSF administration in group B ranged from 6 to 26 days with a median of 12 days and the durations of G-CSF administration in group C ranged from 10 to 23 days with a median of 19 days. With or without G-CSF, there may be no significant difference in the mortality of septicemia following neutropenia caused by chemotherapy in children with acute leukemia.     

松龄血脉康抑制肺动脉高压的实验研究

为观察松龄血脉康胶囊对肺动脉高压大鼠肺动脉压的影响，取１００只健康Ｗｉｓｔａｒ大鼠，其中６０只背部注射野百合碱ｍｏｎｏｃｒｏｔａｌｉｎｅ，ＭＣＴ８０ｍｇ／ｋｇ复制出肺动脉高压模型。再将其分为两组，各３０只，其中一组以标准饲料喂养，另一组加用松龄血脉康胶囊１．５ｇ·ｋｇ－１·ｄ－１。其余４０只健康大鼠做为正常对照组，在实验当天、７天、１４天、２１天、２８天、３５天从各组中随机抽取５只行右心导管测肺动脉压。结果：注射ＭＣＴ后肺高压组２８天时达高峰，但加用松龄血脉康组上升幅度明显小于未用药组。结论：松龄血脉康有显著抑制大鼠肺动脉高压发展的作用     

Wegener肉芽肿8例临床分析

报告８例Ｗｅｇｅｎｅｒ肉芽肿病。本组疾病的病理特点均表现为坏死性血管炎及肉芽形成。临床特点为：发热（３８－４０℃）、鼻塞、鼻衄、咳嗽、口腔及鼻咽部溃疡，皮下结节：Ｘ线表现为肺部多发性结节及空洞阴影，副鼻窦炎症。尿常规检查异常，诊断主要依靠病变组织活检。环磷酰胺和肾上腺皮质激素联合治疗效果显著。     

神经移位修复臂丛神经根性撕脱伤

１９８７年７月～１９９４年６月，对２１例臂丛神经根性撕脱伤采用神经移位修复。其中复合移位４组神经（膈神经、副神经、颈丛运动支、肋间神经）者１例，３组（膈神经、副神经、颈丛运动支）者６例，２组（膈神经、副神经）者９例，１组（膈神经或颈丛运动支或肋间神经）者５例。术中发现臂丛神经变异１例，对４例合并锁骨下动脉损伤者，在神经移位的同时进行血管修复，促进患肢的血液循环，有利于神经的康复。随访到１９例，随访时间为８个月～６年２个月，优良率达７３．７％。认为，神经移位术是修复神经根性撕裂伤的常规方法，合并血管损伤者也应同时修复，对促进神经功能恢复有利     

成人原发性肾病综合征血容量与肾素,醛固酮,心钠素的关系

探讨成人原发性肾病综合征(NS)血容量与肾素、醛固酮及心钠素的关系。方法 应用~(113)mInCl标记转铁蛋白稀释法测定血容量,放免法测定血浆激素水平。对水肿期NS28例、正常26例及其中NS缓解期随访18例进行检测。结果 (1)水肿期NS血容量与正常组无差别,血浆肾素活性(PRA)、血管紧张素Ⅱ(ATⅡ)、醛固酮(Ald)、心钠素(ANP)水平均较正常组高,白蛋白、各激素水平与血容量无显著相关;(2)缓解期与水肿期比较,总的血容量无差异,Ald、ANP显著降低,PRA、ATⅡ则无明显差异;(3)Ald与24小时尿排钠(UNaV)显著负相关。结论 Ald和ANP是NS钠排泄的主要调节因子。

从异叶梁王茶树皮的醇提取物中分离得到两种新的三萜皂苷化学物，异叶梁王茶苷Ⅶ[1]和异叶梁王茶苷Ⅷ[2]；以及一种已知化合物梁王茶苷Ⅱ[3]。经光谱和化学分析，分别鉴定为3－0－β－（2′，4′-O-二乙酰基）－D－吡喃木糖－3β－羟齐墩果－12－烯－28，29双羧酸－28－O－[α－L－吡喃鼠李糖（1－4）－β－D－吡喃葡萄糖（1－6）－β－D－吡喃葡萄糖]酯苷[1]；3－O－β－（3′－O－乙酰基）－D－吡喃木糖－3β－羟齐墩果－12－烯－28，29－双羟酸－28－O－［α－L－吡喃鼠李糖（1－4）－β－D－吡喃葡萄糖（1－6）－β－D－吡喃葡萄糖］酯苷［2］。     

彩色多普勒在心脏起搏器综合征诊断中的应用价值

目的 :探讨运用彩色多普勒血流显像 (CDFI)并结合心电图 (ECG)诊断起搏器综合征 (PMS)的临床价值。方法 :对具有详实临床及ECG资料的心室按需 (VVI)起搏器安置患者 6 0例及对照组 4 8例进行CDEI检查 ,观察起搏组与对照组的三尖瓣返流 (TR)的发生率、返流程度 ,并分析二者之间的相关性。结果 :起搏组出现逆传P波 (即PMS阳性 )者 15例 ,CDFI检测出现TR者 2 0例 ,明显高于对照组 ,且PMS阳性者TR发生率明显高于PMS阴性者 ,表明安置VVI起搏器后出现逆传P波与TR的发生相关性良好。结论 :CDFI对PMS的诊断具有重要意义 ,尤其将ECG与CDFI结合应用有助于诊断率的提高。
