数字减影子宫输卵管造影术

目的:介绍和评价数字减影与自动高压注射器联合应用于子宫输卵管造影(HSG)。方法:自行设计造影用硅胶管使之能与自动高压注射器相联接,用40%泛影葡胺和数字减影方法作造影;随机抽取常规透视点片碘油造影片44份,数字减影泛影葡胺造影片50份进行对照分析。结果:两组比较:清晰度宫腔无显著性差异(P>0.05),输卵管有显著性差异(P<0.05);输卵管通畅率、血管或(和)淋巴管回流率有显著性差异(P<0.05)。盆腔涂布无显著性差异(P>0.05)。结论:采用数字减影与高压注射器行子宫输卵管造影能提高造影质量。

Distribution of rat facial motoneurons and its reorganization following nerve reinnervation]

OBJECTIVE: To examine the distribution of rat facial motoneurons contributing different branches under normal situation and when nerve reinnervation occurred following facial nerve axotomy. METHODS: The normal distribution of motoneurons innervated both buccal and marginal mandibular branches and its reorganization after facial nerve reinnervation was observed using retrograde labeling with fluorescein. RESULTS: Under normal situation, the motoneurons contributing buccall and marginal mandibular branches were primarily distributed in the intermedial and lateral subnucleus in facial nucleus and almost completely overlapped. The two types labeled neurons organized closely, but there were no double-labeled neurons. Although the motoneurons contributing buccall and marginal mandibular branches were primarily overlapped 4 month post-anastomosis, the number of the labeled neurons obviously decreased and the organization got more scattered. There were 10% of buccall branches, 5% of marginal mandibular motoneurons in the dorsal subnuleus, 1% of buccall and 4% of marginal mandibular in dorsal ventral and medial subnucleus. The distribution pattern of the motoneurons 6 month post-anastomosis was similar to that of 4 month post-anastomosis, but the number of the labeled neurons increased, and there were 1%-2% double-labeled neurons. CONCLUSION: The distribution pattern of motoneurons innervated both buccal and marginal mandibular branches indicates that it should exist wide-spread communicating branches, and its reorganization after facial nerve reinnervation suggests that misdirected regeneration occurs among motoneurons innervating different branches.     

辣椒中辣椒素含量的测定

本文作者改进了辣椒中辣椒素含量的测定法。即通过增设洋品空白管以消除色素的干扰;改变 Na_2CO_3溶液的浓度以缓和其操作条件及防止在低温时产生沉淀。本改良法具有简便、快速和重现性好之优点。     

农民工结核病健康教育效果评价

目的 探讨开展结核病健康教育对提高农民工相关知识知晓率和态度正确率的作用.方法 对重庆市南岸区农民工进行结核病相关知识的健康教育,教育方式是由专科医生进行专题讲座.健康教育讲座前后在同一现场统一发放问卷,并当场收回,对教育前后农民工的结核病相关知识作一一配对比较.结果 调查15项内容,其中有14项内容教育前后有显著性差异.教育前农民工结核病知识知晓率为67.5%,教育后知晓率为99.5%;正向态度报告率从教育前的44.1%提高到60.1%.结论 健康教育能提高农民工防治结核病知识知晓率和态度正确率,此方法值得推广.
