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。     

血脂代谢紊乱与冠状动脉病变严重程度的关系

目的:分析血脂代谢异常与冠状动脉狭窄程度的关系.方法:对366例因胸痛而就诊的患者行选择性冠状动脉造影,按冠状动脉狭窄程度分为正常对照组、单支病变组、双支病变组、多支病变组.同时观察患者血脂各成分,并对各组指标进行统计学分析.结果:总胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C),在各组之间存在差异,尤其多支病变组与正常组之间差异显著(P＜0.01).TC、TG、LDL-C随冠状动脉病变加重而增加,HDL-C随冠状动脉病变加重而减少,LDL-C与冠状动脉狭窄程度呈正相关,HDL-C与冠状动脉狭窄程度呈负相关.结论:血脂代谢紊乱与冠状动脉狭窄的发生发展有内在的联系,对于预测有无冠状动脉病变及其进展有一定临床意义.     

中枢神经系统白血病血清神经元特异性烯醇酶测定的临床意义

目的 探讨血清神经元特异性烯醇酶与中枢神经系统白血病之间的关系。方法 对确诊的30例急性白血病患者及匹配的正常人的血清神经元特异性烯醇酶进行测定。结果 中枢神经系统白血病组血清神经元特异性烯醇酶含量21．92 7．5μg/L均明显高于白血病组、对照组，差异有显著性。结论 血清神经元特异性烯醇酶可作为反映中枢神经系统白血病病情的生化指标。     

原发性输尿管癌31例临床分析

目的：提高原发性输尿管癌的术前诊断水平。方法：对南京医科大学第一附属医院1989-2002年间收治的31例原发性输尿管癌的临床资料进行回顾性分析。结果：31例中，肉眼血尿22例(71．0％)，腰痛11例(35，5％)。B超、静脉肾盂造影(IVU)、CT和逆行造影检查的阳性率分别为输尿管腔内占位4例(13．0％)、输尿管腔内占位3例(11．5％)、膀胱或合并膀胱占位8例(36．4％)，输尿管充盈缺损6例(40．0％)。29例患者经手术治疗，其中13例行患侧肾、输尿管、膀胱袖状切除。结论：老年患者反复发作的腰痛及血尿应考虑原发性输尿管癌的可能，造影诊断对本病有较高价值，应作CT及MRU无创检查。     

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.
