不同门奇断流术式对门静脉高压症犬食管下段血管再生的影响

Objective To explore the effect on blood vessel regeneration of distal esophagus in ca-nines of portal hypertension with liver cirrhosis after different procedures with paraesophagastrie devascular-ization. Methods Portal hypertension models were produced in canines by subcutaneous injection of 60% CC14 combined with food restriction. Forty eight model canines were randomly divided into 4 groups: group A, traditional paraesophagastrie devascularization;group B, selective paraesophagastric devascularization;group C, paraesophagastric devascularization plus distal esophageal transaction and reanastomosis with sta-pler;group D,control group. Every group had 12 canines which were randomly divided into A1 ,B1 ,C1 ,D1, A2,B2,C2 and D2 groups after the operation. Canines in groups A1 ,B1 ,C1 and D1 were executed at first month after the operation,and those in groups A2, B2, C2 and D2 were executed at the 6th month after the operation. The distal esophagus was segmented when the canines were executed. The upside and downside of the stoma in group C were distinguished and signed as Ca and Cb. Immunohistochemieal methods were used to detect VEGF,CD34 and FVⅧ-Rag,blood vessel-related factors,in lower esophagus. Results The expres-sion levels of VEGF and CD34 MVD,FⅧ-Rag MVD in groups A1 ,B1 and C1 were lower than those in group D1 one month after the operation (P <0.05). All the indices in group B1 were lower than those in groups A1 and Clb,but higher than those in group Cla (P <0.05). The indices in group Cla were lower than those in group C1b (P < 0.05 ). The indices in groups A2 and B2 were higher than those in groups A1 and B1, re-spectively at the 6th month after the operation (P <0.05). They were higer in outer membrane in group C1a than in group C2a (P <0.05). The indices in group C2b were higher than those in group Clb (P<0.05). Conclusion At the first month after operation, the expression of blood vessel-related factors was declined in three different procedures of paraesophagastric devascularization,which indicated that all three different pro-cedures could diminish the vessels in distal esophagus. The effect in group C was most obvious among all groups. At the 6th month after traditional paraesophagastrie devascularization and selective paraesophagastrie devascularization, the expression of blood vessel-related factors in distal esophagus was declined. But there were no significant changes in the expression of blood vessel-related factors in distal esophagus after parae-sophagastric devascularization plus distal esophageal transaction and reanastomosis with stapler. It indicated that the blood vessel regeneration in paraesophagastric devascularization pins distal esophageal transaction and reanastomosis with stapler was inferior to that in other procedures.     

肝外伤后胆道周期性出血3例报告

1 引言肝外伤后胆道周期性出血是由于创伤引起肝内血管与胆管的病理性沟通的结果。血液通过肝内肝外胆道,进入十二指肠而引起消化道出血,以便血为主。我院1978年5月～1985年6月共收治3例,报告如下。     

血液流变学检测在几种老年病防治中的价值

我国人口组成老龄化已呈明显上升趋势。老年人的发病率高达92．5％。老年疾病和血液流变学的改变密切相关，从血液流变学角度着手，对老年疾病进行防治研究，是一个重要课题。     

运动中猝死

所谓猝死是指发病24小时内不可预见的死亡，不包括交通事故等外伤性死亡。在运动中40岁-59岁练剑术的人相对危险率最高，其次为滑雪，登山和棒球，高尔夫及游泳比跑步的相对危险率低。60岁以上的人打高尔夫球和登山的危险率要有所增高，其它的运动项目同40岁-9岁赛跑的人的危险率相同。30岁以下的年轻人运动中猝死的疾病主要是肥大型心肌病。

浆膜积液恶性肿瘤细胞学诊断

本文报道18例资料较全的浆膜积液恶性肿瘤涂片。 1 方法与结果 1.1 方法:送检标本100～200ml,将上部液体轻轻倒去收集底部沉淀离心,将沉淀物推片,涂片应厚薄均匀,并在来干之前放于无水酒精内固定。如血液太多,可在离心后取红细胞表层或中层液体推片,如为脓液可直接推片,如标本细胞成分太少,可采用二次离心法。涂片行巴氏染色。     

吲达帕胺对高血压病患者降压作用的临床研究

３４例高血压病患者服国产吲达帕胺后，血压持续缓慢下降，ＴＰＲ显著下降，血浆肾素活性（ＲＡ）、血管紧张素Ⅱ（ＡＴ－Ⅱ）和醛固酮（ＡＤＳ）浓度显著增高，而心率及血儿茶酚爱（ＣＡ）水平无显著变化。治疗４周对全轿Ｃｄ，Ｐｂ，红细胞（ＲＢＣ）及血浆Ｚｎ，Ｃｕ，Ｎａ，Ｋ，Ｍｇ浓度无显著影响。其总疗效为８８．２４％，表明国产吲达帕胺是一种疗效显著而副作用低的降压药物。
