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.

经输尿管镜钬激光碎石治疗输尿管结石

目的探讨经输尿管镜钬激光碎石治疗输尿管结石的临床效果. 方法 90例输尿管结石,经尿道、膀胱置入10°输尿管镜抵达结石处,将光纤头直抵结石,设置工作能量0.8～1.5 J,频率8～10 Hz,采用连续脉冲方式粉碎结石. 结果3例进镜失败(输尿管镜无法到达结石部位)改开放手术,1例输尿管穿孔改开放手术;86例碎石成功,单次钬激光碎石成功率为95.6%(86/90).手术时间30～80 min,平均55 min.术后住院1～5 d,平均2.5 d.86例随访1～3个月,69例病程＜6个月、肾积水＜4 cm,肾积水完全消失;17例病程＞6个月、肾积水＞4 cm,术后患肾均有不同程度积水,但较术前明显改善. 结论经输尿管镜钬激光碎石治疗输尿管结石效果理想,创伤小,并发症少,可作为输尿管中、下段结石的首选治疗方法.     

Expression, purification and molecular modeling of recombinant fibrinogenase [IV], a metalloproteinase from Deinakistrodon acutus venom.

A novel metalloproteinase, recombinant fibrinogenase IV (rFIV(a)), was expressed and purified from Deinakistrodon acutus venom. It was a single chain protein with an apparent molecular weight 27 kDa and an isoeletric point of pH 7.1. RFIV(a) cleaved preferentially the Aalpha-chain and also cleaved Bbeta, gamma-chains of fibrinogen when the incubation time was prolonged. The proteolytic activity was inhibited by EDTA, l-cysteine, and DTT, indicating rFIV(a) was a metalloproteinase requiring disulfide bonds for its activity. It kept above 85% of the initial activity from pH 4.5-11, showed an equal maximum activity at the temperature range from 30 to 50 degrees C, and was inactivated by Zn2+, Cu2+ and Cd2+. Homology modeling of rFIV(a) showed that two highly conserved disulfide bonds (Cys159-Cys164 and Cys117-Cys197) was maintained from its structure, and it exhibited the characteristic conserved motif H142E143XXH146XXGXXH152, whose three histidine residues were involved in binding of the catalytically essential zinc ion. This work demonstrates the expression, purification and characterization of recombinant fibrinogenase IV, which belongs to class P-I metalloproteinase from D. acutus venom.

老年患者不稳定性股骨转子间骨折的术式选择

目的探讨不同的内固定方式在老年患者不稳定性股骨转子间骨折治疗中的应用。方法参照Evans分型,85例老年患者股骨转子间骨折,不稳定性77例,稳定性8例,分别应用不同内固定治疗,其中Gamma钉20例、重建钉25例、动力髋部螺钉(DHS)和动力髁部螺钉(DCS)40例。结果术后随访79例,均获得骨折愈合,愈合时间4～7个月,平均5.2个月,其中大于5°髋内翻者有12例。根据患者骨折愈合、关节活动、主观感觉与生活能力恢复等因素制定疗效评定标准,优良率为84.8%(67例)。未发生因本手术所致内科合并症加重或患者死亡。结论髋内翻是老年患者不稳定性股骨转子间骨折内固定术后的主要并发症。Evans分型对选择内固定具有指导意义。结合老年患者骨质疏松情况,针对不同骨折类型选用适当的内固定器械,可以提高不稳定性转子间骨折的疗效。
