经皮腔内肾动脉成形术及自体肾移植治疗肾血管性高血压(附7例报告)

自1980到1986年,我院泌尿外科对4例单纯右侧肾动脉狭窄(RAS)性和3例双侧RAS性高血压病人进行了治疗。7例右侧 RAS皆进行了自体肾移植治疗,其中3例双侧RAS者采用PTA治疗,全部病人术后8天内血压皆恢复正常,随诊10个月到6年,无复发且都恢复工作。1例17岁女孩,术后2年结婚,又2年生一女孩,母女健在血压维持正常。     

不同起搏模式对病人生存质量影响的调查研究

[目的]探讨不同起搏模式对病人生存质量（QOL）的影响。[方法]以健康调查问卷（SF一36量表）对112例不同起搏模式病人进行问卷调查，比较3种起搏模式下病人的QOL水平。[结果]除机体疼痛、角色情绪2个维度外其余6个维度（生理功能、角色限制、活力、社会功能、精神健康、总体健康）3种起搏模式间比较差异有统计学意义（P〈0．05）。[结论]应用AAI型、DDD型起搏器的病人生存质量优于VVI型起搏。     

聚氯乙烯增塑糊流变行为的研究——Ⅳ.表面活性剂的影响

本文研究了各类表面活性剂对聚氯乙烯增塑糊流变行为的影响。阴离子表面活性剂使其增塑糊有较高致流值,呈明显假塑性流动;阳离子和非离子表面活性剂使其增塑糊有低的表观粘度,接近牛顿型流动。测定了聚氯乙烯粒子表面的Zeta电位和接触角,并讨论了表面活性剂影响增塑糊流变性能的机理。     

A PRELIMINARY STUDY OF THE ACTION OF MALE HOR MONE ON HIGH DENSITY LIPOPROTEIN-CHOLESTEROL

Plasma testosterone and estradiol are determined in 72 patients with abnormal high density lipoprotein. cholesterol (HDL-C) and high density lipoprotein cholesterol/total cholesterol (H/T) ratio values, and in 72 randomly chosen males with normal HDLC and H/T values. The results showed that plasma testosterone levels in the groups with abnormal HDL-C and H/T were obviously lower than those in the controls. Statistically significant differences were found in all the abnormal groups in comparison with the controls (P0.20). Testosterone levels lowered further with increasing age in the groups with abnormal HDL-C and H/T., the most obvious drops were in the groups around 56 years of age (P<0.005). The data indicate that male hormone deficiency may reduce HDL-C and H.'T and facilitate the process of atherosclero_is. Therefore, it seems rational to treat such patients with male sex hormone preparations or to use the traditional Chinese medicines which strengthen Yang (maleness) in a new attempt to treat and prevent CHD.     

河北省中药混乱品种鉴别研究——6.蕲蛇及其伪品的鉴别

按照中国药典1985年版蕲蛇为蝰科动物五步蛇除去内脏的干燥体。近年在河北省的药村商品中,发现有游蛇科动物滑鼠蛇混入其中,充当蕲蛇。作者应用解剖、组织切片的方法,研究了蕲蛇与滑鼠蛇在形态组织上的鉴别特征。它们的主要区别在于:鳞片、体表花纹、牙齿、鼻骨的形态;椎骨的形态与组织特征。据此可以鉴别蕲蛇与滑鼠蛇的真伪。     

肠外营养与生长激素联合应用对外科大手术术后患者蛋白代谢的影响

目的观察肠外营养与生长激素联合应用对大手术术后患者蛋白代谢的影响。方法将拟实施外科大手术(四类以上手术)熏APACHE-Ⅱ评分>7分的患者30例,入院后随机分为3组熏A组穴n=10雪押肠外营养治疗与生长激素穴金磊赛增雪联合治疗组(PN+GH)鸦B组穴n=10雪押肠外营养治疗组(PN)鸦C组穴n=10雪押正常补液组。其中A组在术后第2天开始给予生长激素皮下肌注,连续7d。结果术后8d内,B、C组患者均处于负氮平衡状态,血清白蛋白与胰岛素样生长因子-Ⅰ(IGF-Ⅰ)维持较低水平,A组在术后5d机体开始恢复氮平衡,血清白蛋白与IGF-Ⅰ水平逐渐上升,A组与B、C组比较差异有显著性(P<0.05)。结论较大的外科手术打击后,单纯给予常规的肠外营养要素不能被机体有效的利用,GH能够提高机体对肠外营养要素的利用率,促进机体蛋白合成。     

血清TPS浓度在消化道肿瘤中价值的研究

共选择３０例消化道肿瘤病人，其中食管癌，胃癌，大肠癌各１０例，设健康献血者３０例，对两组血清特异型组织多肽抗原浓度进行了检测，结果肿瘤组血清ＴＰＳ浓度明显高于健康人。消化道肿瘤阳性检出经达７０％，其中食管癌８０％，胃癌６０％，大肠癌７０％。消化道肿瘤合并淋巴转移阳性检出率达７６．９％，其中食管癌１００％，胃癌６６．７％，大肠癌７０．０％。随着病程发展，血清ＴＰＳ浓度呈现升高趋势。     

PREVIOUS INTRAVENOUS CHEMOTHERAPY DOES NOT ALTER RESPONSE RATE OR SURVIVAL TIME OF PATIENTS WITH HEPATIC METASTASES FROM COLORECTAL CANCER TREATED BY HEPATIC ARTERY CHEMOTHERAPY

Background : The present paper addressed the issue of whether pretreatment with intravenous (IV) chemotherapy affects response rate or survival in patients receiving hepatic artery chemotherapy (HAC). Methods : Case note reviews of 164 patients treated in a teaching hospital from June 1990 to July 1996 were carried out. Results : The response rate and carcino-embryonic antigen (CEA) fall in the two groups was almost identical. There was a nonsignificant survival advantage in the non-pretreatment group. Conclusions : Previous administration of IV chemotherapy did not affect the CEA response of patients receiving HAC.
