外伤性腮腺腺体瘘的手术治疗

腮腺受到创伤，早期处理不当，易产生腮腺瘘，瘘口通向面颊部皮肤，涎液激惹局部皮肤，出现糜烂、发红或伴发湿疹，给患者带来很大痛苦。我科自１９７７年～１９９６年间收治创伤性腮腺腺体瘘１９例，采用外科手术治疗，效果良好。现总结报道如下。临床资料本组１９例患者...     

微血管性心绞痛与胰岛素抵抗关系的探讨

目的：探讨微血管性心绞痛患者与胰岛素抵抗的关系。方法：测定了14例微血管性心绞痛患者（X组）血脂、空腹和餐后2h血糖、胰岛素水平变化，并选择20例正常人（C组），15例冠心病人（D组）作对照。结果：①X组与D组餐后2h胰岛素、胰岛素／血糖比值显著高于C组（P＜0．05）。②X组的糖耐量异常者占71．4％，D组占40％，均高于C组，X组比D组更高（P＜0．10）。③餐后2h胰岛素与甘油三酯和apoB呈正相关，与apoA1呈负相关。结论：微血管性心绞痛存在糖耐量异常、胰岛素抵抗、餐后高胰岛素血症及血脂代谢紊乱，与内分泌代谢的X综合征有其共同点。     

有机药物化学中不对称合成手性产率及其随温度变化规律的研究

本文首次用分子力学计算产物或过渡态分子内张力能来估算热力学或动力学,控制不对称合成反应生成的立体异构体的相对比例,并从热力学上推导了这一比例随温度变化公式,而且从实验上得到证明,在有机或药物化学最富有挑战性的领域——不对称合成中具有重要的理论和实际意义。     

10Gyγ线照射后小鼠两相邻肠段运动变化

本文用同时记录两相邻空肠段的收缩活动来观察经10Gyγ线照射后小肠运动的变化,以了解照射后是否出现逆蠕动,以便进一步分析肠套叠形成的原因.结果表明,照射后两相邻肠段出现强度不一的收缩活动,并且可以产生逆蠕动;但是这种逆蠕动发生的机率是不大的.本实验未观察到逆蠕动发生的规律性.因此,逆蠕动的产生可能是照射后发生肠套叠的部分原因.

碘盐防治对改善缺碘地区儿童智力的调查分析

众多资料研究证实缺碘地区儿童智力明显低于非缺碘地区。为了解碘盐防治后缺碘地区儿童智力水平,验证防治效果,对我县实施碘盐防治措施20余年的缺碘地区什字乡(下称防治区)学龄儿童进行了智力调查,并以未经防治的缺碘地区石岔乡(下称未防治区)和非缺碘地区黄锋堡乡作对照。对象和方法一、一般情况:什字乡位于六盘山东侧腹地(?)区。是原地甲病重病区。水碘范围0.1～     

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.
