不同时期军队疗养员消化性溃疡的流行病学调查分析和对比

目的分析对比不同时期军队疗养员消化性溃疡（PU）的患病情况。方法采用相同的病史采集和问卷调查法，以胃镜检查资料为确诊手段，对1990年和2005年两个年度的疗养员进行消化性溃疡流行病学调查。结果1990年军队疗养员消化性溃疡的患病率为158／1168人（13．53％）；2005年为56／1239人（4．52％），二者相比有显著性差异P〈0．01。结论由于保健意识、生活方式和药物治疗的干预，十五年间，军队疗养员消化性溃疡的发病率显著下降。     

二十二碳六烯酸对神经细胞生长发育的影响

目的：观察二十二碳六烯酸（DHA）对神经细胞生长发育的影响。方法：将无血清培养的新生大鼠大脑神经细胞分为实验组和对照组，实验组加入0.33mol/L乳化DHA 40μl。对两组细胞进行形态学观察及蛋白质含量测定。结果：实验组大脑神经细胞的突起生长速度、胞体面积和直径、神经细胞存活率及蛋白质含量均显著高于对照组。结论：DHA对神经细胞的生长有促进作用，这一作用可能与促进神经细胞蛋白质合成有关。     

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.

Pleural cryptococcosis in the acquired immune deficiency syndrome

Pleural cryptococcosis is extremely rare. We report the first case of cryptococcal pleural effusion in association with the acquired immune deficiency syndrome. Pleural effusion without the evidence of pulmonary parenchymal involvement was the initial and only clinical finding leading to the diagnosis of disseminated cryptococcosis. The pleural effusion resolved spontaneously prior to amphotericin B therapy.
