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.

心理社会因素对医学生自信水平的影响

目的：寻找影响医学自我评价的有关因素，为提高他们的自信程度提供参考。方法：采用个人评价问卷（PEI）、应付方式问卷、症状自评量有（SCL－90）及一般情况调查表（自制）对450例学生进行调查，结果：性别、身高、体重、班委、恋爱、母亲文化程度，父亲健康状况，家庭经济状况，解决问题，求助等因素与PEI量表总分量呈显著正相关，SCL－90各因子呈显著分和总均分及自责，幻想，退缩，合理化与PEI量表总分负相关。结论：医学生的自我评价受到自身心理状况，应付方式、家庭状况等因素的影响。     

交感神经在肺泡缺氧性肺血管收缩反应中的作用

在大鼠毁髓模型上观察缺氧与不缺氧情况下电刺激肺血管的脊髓交感中枢时体、肺循环的变化。常氧时电刺激脊髓T_(1～3)节段时P_(pa)、PVR增高(P<0.05);毁髓去神经支配大鼠吸入12%O_2低氧气体后仍能引起肺血管收缩反应(HPV),但PVR上升幅度较正常大鼠降低。在缺氧基础上电刺激T_(1～3)节段引起P_(pa)、PVR大幅度增高(P<0.05),约为常氧时电刺激效应的二倍;酚妥拉明可抑制这一反应。提示交感神经兴奋对HPV的形成有一定的促进作用。缺氧时体循环对交感兴奋的反应减弱。
