Studies on the relationship between transaldolase activity and testosterone synthesis in Leydig cells of pubertalmice

Objective: To study the relationship between transaldolase activity, protein expression and testosterone synthesis in Leydig cells of pubertal mice. Methods: Leydig cells were cultured for 2 hours and 8 hours, to the Stimulation Group, hCG was added and to the Controls, only the vehicle. The testosterone concentration was then determined by enzyme-linked immunoadsordent assay (ELISA) and the transaldolase activity and protein expression by Western blot. Results: (1) Both the testosterone concentration and the transaldolase activity in both Stimulation Groups were significantly higher than those in the corresponding Controls (2 h: p<0.05-0.01; 8 h: P<0.001); (2) The ratios of the A isoform, the B isoform and the total transaldolase protein to β-actin between the Stimulation and Control Groups did not differ signifi-cantly. Conclusion: hCG stimulates the transaldolase activity as well as the testosterone synthesis in the Leydig cells of pubertal mice, indicating a positive relationship between them.     

Familial Juvenile Nephronophthisis in Two Siblings — Histological Findings at an Early Stage —

We present two female siblings with familial juvenile nephronophthisis (FJN) which was diagnosed at the early stage of renal failure. Diagnosis was made during the investigation of anemia in case 1 and by a subsequent family survey in case 2. Most patients with FJN are not identified until the terminal stage of renal failure and such cases have rarely been reported in Japan. Case 2 had a reduction in the maximum urinary concentration ability but no azotemia, and among the FJN patients reported in Japan so far she has the least advanced renal disease. Histological examination of the renal biopsy in case 1 showed typical findings of FJN, such as thickening and lamination of the tubular basement membrane (TBM), interstitial fibrosis, and round cell infiltration of the interstitium. In case 2, renal biopsy revealed an irregular marked thickening of the TBM with trivial interstitial changes and a normal glomerular appearance. The histology of these two cases suggests that the TBM may be the primary site affected in FJN.     

Fibula osteoseptocutaneous flap for mandible reconstruction

The fibula free flap has become an established flap for mandible reconstruction when vascularized bone is desirable. Recreating mandibular contour, providing soft tissue coverage, and restoring masticatory function are equally important in mandible reconstruction, and these can be provided by the fibula osteoseptocutaneous flap. This article is a summary of the anatomy, indications, and operative technique of the fibula osteoseptocutaneous flap accumulated from 49 consecutive mandible reconstructions. © 1994 Wiley-Liss, Inc.     

C型臂X线机引导下经皮双侧骶髂拉力螺钉固定治疗骶骨H形骨折

目的探讨骶骨H形骨折可行的治疗方法。方法运用C型臂X线机引导下经皮双侧骶髂拉力螺钉固定治疗骶骨H形骨折15例。结果15例患者均获随访，随访时间7—34个月，骨折临床愈合时间3～5个月，术后均未留下明显行走障碍，下蹲等活动接近正常。结论在C型臂X线机精确引导下，经皮双侧骶髂拉力螺钉固定技术能有效地固定骶骨H形骨折中的垂直骨折，纠正骨盆垂直方向移位，操作简洁安全，疗效可靠。     

血清TNFα与糖尿病患者的关系

目的了解糖尿病(DM)患者与血清肿瘤坏死因子的关系及意义.方法采用放射免疫法对75例患者组和43例正常组进行了同步检测TNFα的含量.结果患者组血清TNFα明显高于正常组并与糖化血红蛋呈正相关,且与胰岛素敏感指标呈负相关,而DM患者抗谷氨酸脱羧酶抗体阳性组的血清TNFα水平较阴性组有明显增高.结论糖尿病患者血清TNFα水平的异常增高,可推测与长期的糖代谢紊乱、自身免疫性的胰岛损伤及胰岛素抵抗有关.     

粗糙脉孢菌漆酶基因的克隆及在毕赤酵母中的初步表达

采用连续延伸PCR方法克隆到粗糙脉孢菌（Neurospora crassa）漆酶基因，并将其克隆到表达载体pPIC9k，重组质粒经线性化、电激转化Pichia pastoris KM71，部分阳性克隆的PCR结果表明：漆酶基因已整合到巴斯德毕赤酵母染色体上，重组菌经甲醇诱导后3～5d产漆酶量最高，为2-3U／mL。     

对学习困难学生的施教对策

教师常常偏爱成绩好的学生，而对学习困难学生则在情感上、精力上和研究上投入不够。对学习困难学生的认识往往集中在他们身上的缺陷，而忽视了他们具有的学习潜能。教学实践证明，合理的施教是开发其潜能、促进其转化的关键。     

心理咨询门诊与普通专科门诊抽样对照分析

目的调查本院心理咨询门诊与普通专科门诊就诊疾病谱的差异,了解两者在精神分裂症治疗上的差异以及对预后的影响。方法以1/20抽取1995～2002年间的门诊病例进行统计分析,其中心理咨询门诊病例79份,普通专科门诊病例143份。自行设计表格对就诊者的性别、年龄、初诊诊断和服药、住院情况进行统计,比较两者就诊疾病谱的差异,以及两者在精神分裂症治疗上的差异和对预后的影响。结果(1)心理咨询门诊就诊者以心境障碍和神经症为主(分别达25%和27%),普通专科门诊以精神分裂症为主(48%,t=14．66,P＜0．005)；(2)在精神分裂症的治疗上,心理咨询门诊第二代抗精神病药(SGAs)的应用率较高(50%vs 14%,P＜0．005),两处就诊者的预后也存在差异。结论心理咨询门诊与普通专科门诊在初诊中存在一定的分工；两者对精神分裂症治疗存在差异,这种差异可能直接导致精神分裂症的预后,我国有待建立规范的精神分裂症治疗指南；全社会对非重性精神疾病的重视程度仍有待加强。     

力学在食管胃腔内弹力环扎吻合术的应用

本文探讨食管胃腔内弹力环扎吻合术的力学机理。这是一种不用任何缝合材料或吻合器进行胃食管吻合的新技术,我们已成功应用于临床。取临床所用的乳胶管按该材料多向异性特征、实验条件以及弹力环数目分为8组,每组3个样品进行各种体外力学试验。通过应力—应变(拉力—伸长)关系曲线和定伸长松驰试验确定它的力学特性是一种粘弹性材料。根据实验所得的应力换算为弹力环对食管和胃组织所施加的最佳压力(压强)是4.23±0.23Kg/cm~2,这样才能保证这一种新颖的吻合术可达到简便、安全、可靠的目的。
