尿毒症患者的性激素变化及其临床意义探讨

目的 :探讨女性尿毒症患者卵巢功能障碍的发病情况及其临床意义。方法 :应用酶免疫法 (EIA)测定了2 3例更年期前女性尿毒症非透析患者、15例透析患者及 2 9例健康献血者中促卵泡素 (FSH)、泌乳素 (PRL)、促黄体素 (LH)、雌二醇 (E2 )及孕酮 (P)的水平。结果 :尿毒症女患者PRL、FSH及LH均较健康对照组升高 ,而孕酮值显著降低 ,对此均有显著差异 ;且尿毒症女患者PRL升高、孕酮值降低与肾小球滤过率 (GFR)呈明显相关。透析患者较非透析患者PRL升高更为明显 ,孕酮值亦较非透析患者有所升高 ,但无显著意义。结论 :尿毒症女患者的排卵障碍及月经紊乱等都与尿毒症的严重程度相平行。透析并不能改善尿毒症女患者的卵巢功能障碍 ,只有纠正与改善肾功能 ,才能使尿毒症女患者的卵巢功能得以改善     

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.

甲醛固定源同种异体骨移植材料的体外实验研究

OBJECTIVE: To conduct an in vitro study to assess the preliminary possibility of using formalin-fixed, instead of fresh, human bone tissues for allografting. METHODS: Fresh cadaveric bone tissues were fixed by formalin for more than 6 months and dissected into 5 mmx5 mmx5 mm pieces and 5 mmx5 mmx40 mm sticks, followed by chemical treatments to prepare the allograft bone materials. When alls treatments were completed, the bone grafts were centrifuged and their properties and cellular compatibility assessed in comparison with the currently used bone grafts clinically. RESULTS: The residual formaldehyde of the fixed allograft bone material was much below the controlled level and no significant differences were noted between the bone graft materials tested in regard to the chemical and mechanical properties and biocompatibility. CONCLUSION: This material we have prepared may meet the clinical demands for bone grafting, with good biocompatibility and less chance for infection by pathological agents.     

宫颈鳞癌中erbB3、erbB4基因蛋白表达与细胞凋亡和增殖的相关性研究

目的　探讨原癌基因erbB3、erbB4与细胞凋亡和增殖的关系 ,为该基因作用机制提供新线索。方法　分别采用免疫组化、DNA末端标记技术 (TUNEL法 )和HE染色检测 5 0例宫颈鳞癌中erbB3、erbB4基因蛋白表达及凋亡指数 (AI)和增殖指数 (MI)。结果　宫颈鳞癌中erbB3、erbB4表达率分别为 5 2 .5 %、44 .0 % ,AI、MI值分别为 5 .5 0± 4.10和 4.18± 3 .63 ,随着宫颈癌恶性程度增高、FIGO分期进展、肿瘤体积的增大和淋巴结转移组 ,erbB3、erbB4表达率增加 ,AI、MI值也增高 ,但差异仅在分化程度上有显著性 (P <0 .0 5 )。双变量相关分析显示erbB3、erbB4表达与AI、MI间无相关性 (r3=0 .10 98、0 .12 3 6,r4 =0 .2 15 1、0 .2 5 5 8,P >0 .0 5 )。结论　erbB3、erbB4和AI、MI预示着宫颈癌恶性潜能 ,但不能作为预后有用指标。erbB3、erbB4的作用机制可能不是通过细胞凋亡或增殖起作用     

STUDIES ON NUTRITION AND PRECANCEROUS LESIONS OF THE ESOPHAGUS IN THE ADOLESCENTS

This paper reports the prevalence of chronic esophagitis and nutritional status among 538 young persons aged 15 to 26 years from the high risk area for esophageal cancer. Of these subjects, 166 were from households with history of esophageal cancer and 372 were from households without history of esophageal cancer. The Incidences of chronic esophagltis among male and female adolescents were 37. 6% and 36% respectively, which was significantly higher than those in the low risk area (17%). The frequency of chronic esophagltis in the adolescents in the households with history of esophageal cancer was aiso higher than in those In the households without history of esophageal cancer. The deficiencies of vitamins, especially of riboflavin and ascorbate, are prevalent and severe among these adolescents. Ascorbate deficiency Is correlated with the severity of the chronic esophagltis. These results indicate that chronic esophagltis may be involved in the natural history of esophageal carclnogenesis.

原发性干燥综合征与人类组织相容性抗原—DRβ基因

原发性干燥综合征（ＰＳＳ）的病因未明，其中可能涉及遗传因素。用序列特异性引物聚合酶链反应（ＰＣＲ－ＳＳＰ）法对７０例ＰＳＳ患者和１３６名正常人进行人类组织相容性抗原（ＨＬＡ）－ＤＲβ基因分型。发现ＰＳＳ患者群体的ＨＬＡ－ＤＲ３、ＤＲ５２及ＤＲ２的基因频率明显高于正常对照组，而ＨＬＡ－ＤＲ５及ＤＲ９的基因频率则相反，提示ＰＳＳ的发病与ＤＲ３、ＤＲ５２及ＤＲ２呈正相关；而和ＤＲ９、ＤＲ５呈负相关。２个ＰＳＳ患者家族的姐妹与患者具有相同的遗传因素，且和ＰＳＳ患者群体测定的正相关基因相一致。ＰＳＳ患者的主要自身抗体（抗ＳＳＡ抗体及抗ＳＳＢ抗体）与ＨＬＡ－ＤＲ５２之间有明显的相关性，因而表明ＰＳＳ的发病和遗传因素有关。
