妊高征孕妇压力反射功能的改变

目的研究妊高征孕妇心率变异性(HRV)、血压变异性(BPV)和压力反射敏感性(BRS)的改变.方法用无创伤测定和频谱分析方法,检测31名正常妊娠孕妇和19名中、重度妊高征孕妇的HRV、BPV和自发性BRS,数据用SPSS 10.0软件分析.结果妊高征组和正常妊娠组相比,HRV各指标有下降趋势,但无统计学意义(P>0.05).妊高征孕妇BPV的低频成分显著高于正常妊娠孕妇(P<0.05),BRS较正常妊娠孕妇降低(P<0.05).结论妊高征孕妇交感神经对血压调节的活动性较正常妊娠孕妇增强;压力反射功能受损可能是妊高征发病过程中一重要环节.     

前列腺素E1对大鼠肝脏缺血再灌注损伤的保护作用

目的 探讨前列腺素E1（PGE1）对肝脏 因再灌注损伤的保护作用。方法 制作常温下大鼠部分肝叶缺血再灌注模型，于缺血前经门静脉给予PGE1，45min后恢复血流灌注，并于1h后取门静脉血测定血清谷草转氨酶（GOT）、谷丙转氨酶（GPT）、乳酸脱氢酶（LDH）、肿瘤坏死因子－α（TNF－α）及内皮素1（ET－1），同时取缺血肝叶行病理组织学检查。结果 缺血再灌注组GOT、GPT、LDH及TNF－α和ET－1均明显高于正常对照组，PGE1组则明显低于缺血再灌注组。PGE1组的肝脏病理组织学改变明显轻于缺血再灌注组，并接近正常对照组。结论 PGE1对肝缺血再灌注具有保护作用。

BIOEQUIVALENCE BETWEEN rhGH FOR RECONSTITUTION AND READY-TO-USE rhGH IN TWO LIQUID FORMULATIONS

Objective To evaluate the bioequivalence between recombinant human growth hormone （rhGH） for reconstitution, and two dosages of liquid formulation of rhGH [ （151U） 5mg or （301U） lOmg per 3ml ]. Methods The study drugs were tested in a randomized, single-blind and three-period crossover studies in 24 healthy male subjects. The three drugs were administered by subcutaneous injection at a dose of O. 21U/kg body weight. A continuous somatostatin infusion was given in order to suppress the secretion of endogenous GH. The ve- nous blood samples were drawn at different time points to test the serum concentration of GH. The pharmacokinetic parameters were analyzed by statistical methods. Results 90% confidence intervals （CI） of AUC0-24h among three products were all within 80% - 125% interval （ 103. 4% - 116. 5%, 105. 7% - 119. 6% and 91.9% - 103. 7%, respectively）, and the Cls of C,~ among three products were all within 70% - 143% interval （91.9% - 114. 0%, 103. 7% -127. 2% and 81.6% -97. 4%, respectively）. There was no statisitical difference of tmax among all the three products. Conclusion These data demonstrate that there is bioequivalence between rhGH for reconstitution and two liquid formulations of rhGH.     

骨盆骨折合并出血性休克的救治

目的探讨骨盆骨折合并出血性休克的救治方法。方法回顾性分析2001年1月-2006年2月收治的85例骨盆骨折合并出血性休克患者的临床资料,根据AIS-ISS创伤评级标准评定伤情。结果本组患者ISS评分均大于16分,平均(33．3±15．5)分,成活60例,死亡25例,抢救成功率70．6％。结论骨盆骨折合并出血性休克的死亡率较高,死亡患者大部分发生在急诊抢救过程中,早期应用合理的抢救措施是降低死亡率的关键。     

Developmental changes of glutamate acid decarboxylase 67 in mouse brain after hypoxia ischemia

Objective To study the developmental changes of glutamic acid decarboxylase-67 (GAD-67, a GABA synthetic enzyme) in normal and hypoxic ischemic (HI) brain. Methods C57/BL6 mice on postnatal day (P) 5, 9, 21 and 60, corresponding developmentally to premature, term, juvenile and adult human brain were investigated by using both Western blot and immunohistochemistry methods either in normal condition or after hypoxic ischemic insult. Results The immunoreactivity of GAD67 was up regulated with brain development and significant difference was seen between mature (P21, P60) and immature (P5, P9) brain. GAD67 immunoreactivity decreased in the ipsilateral hemisphere in all the ages after hypoxia ischemia (HI) insult, but, significant decrease was only seen in the immature brain. Double labeling of GAD67 and cell death marker, TUNEL, in the cortex at 8h post-HI in the P9 mice showed that (15.6±7.0)% TUNEL positive cells were GAD67 positive which was higher than that of P60 mice. Conclusion These data suggest that GABAergic neurons in immature brain were more vulnerable to HI insult than that of mature brain.     

做好当前临床外科教学工作的思考

应从提高教师队伍素质、提倡主动式教学、专科教育、指导学生处理好医患关系、提高法律意识和自我保护意识、制定统一的教学内容和目标等方面，做好临床教学工作。
