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～     

天蚕素A-蛙皮肽杂合肽基因的表达及产物抗菌活性测定

目的 研究天蚕素A-蛙皮肽杂合肽基因[CA（1-8）-MA（1-12）]抗菌肽的抗菌活性。方法 将天蚕素A-蛙皮肽杂合肽基因抗菌肽的人工基因克隆到具有自切割功能的表达载体pTYB12上，并在大肠杆菌（E.coli)BL21(DE3)中进行表达，表达产物用几丁质树脂进行了亲和吸附，自切割后洗脱得到抗菌肽，进行透析以去除盐类物质，最后用大肠杆菌与金黄色葡萄球菌进行活性检测。结果 天蚕素A-蛙皮肽杂合肽[CA（1-8）-MA（1-12）]对大肠杆菌与金黄色葡萄球菌均有一定的抗菌活性。结论 天蚕素A-蛙皮肽杂合肽具有抗菌活性。其抑瘤活性的研究还有待于进一步研究。     

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。     

派罗欣治疗慢性乙型病毒性肝炎的观察与护理

目的探讨乳腺癌术后胸部气压固定带的制作及临床应用价值。方法将64例乳腺癌术后患者随机分为观察组和对照组各32例,对照组采用传统的绷带加压包扎,观察组采用自行设计并制作的胸部气压固定带加压包扎。观察两组术后引流量、拔管时间及并发症的发生情况。结果观察组皮下积液发生率显著低于对照组（P〈0.05）,术后24h引流量、置管时间显著少于/短于对照组（均P〈0.01）。结论乳腺癌术后使用胸部气压固定带加压固定可减少渗出,缩短置管时间,降低皮下积液发生率。     

血液流变学检测在几种老年病防治中的价值
