成人原发性肾病综合征血容量与肾素,醛固酮,心钠素的关系

探讨成人原发性肾病综合征(NS)血容量与肾素、醛固酮及心钠素的关系。方法 应用~(113)mInCl标记转铁蛋白稀释法测定血容量,放免法测定血浆激素水平。对水肿期NS28例、正常26例及其中NS缓解期随访18例进行检测。结果 (1)水肿期NS血容量与正常组无差别,血浆肾素活性(PRA)、血管紧张素Ⅱ(ATⅡ)、醛固酮(Ald)、心钠素(ANP)水平均较正常组高,白蛋白、各激素水平与血容量无显著相关;(2)缓解期与水肿期比较,总的血容量无差异,Ald、ANP显著降低,PRA、ATⅡ则无明显差异;(3)Ald与24小时尿排钠(UNaV)显著负相关。结论 Ald和ANP是NS钠排泄的主要调节因子。     

儿童间歇性深吸气症临床探讨

探讨儿童间歇性深吸气症的诊断及治疗.方法 对我院1990～1996年以间歇性深吸气为主诉就诊的60例儿童进行病因、临床表现、诊断方法和主要治疗措施等方面的临床分析.结果 此症患儿有心理障碍和情绪因素的占63.3%,其中最重要的是家庭和学校环境因素的影响,习惯因素占20%.另外,还有气质因素的影响等.并提出本症的诊断依据.通过心理治疗,绝大多数病例可以治愈.结论 本症是一种较常见的心因性疾病,提出的诊断依据是实用的,心理治疗可获得满意疗效.     

家兔缺血与再灌流肾内脂质过氧化物含量的变化

本研究发现:家兔缺血60min(未再灌流)肾皮质和髓质内,脂质过氧化物含量均显著降低;缺血60min再灌流15min的肾皮质和髓质内,脂质过氧化物含量均显著增加。实验提示:缺血再灌流贤内氧自由基“爆发性”生成所引发的脂质过氧化可能是肾缺血性损伤的重要机制之一。     

显微内窥镜下治疗腰椎间盘突出症和腰椎管狭窄症

目的探讨显微内窥镜(MED)治疗腰椎间盘突出症和腰椎管狭窄症的临床效果。方法MED下切除增生内聚的关节突、肥厚的黄韧带及突出的椎间盘，彻底解除对硬膜、神经根的压迫。结果随访324例，按中华骨科学脊柱学组腰背痛手术评定标准，优297例，良14例，差13例，疗效优良率达96．0％，结论MED损伤小、恢复快、疗效好。     

肺切除术影响围手术期右心功能

Objective To investigate the changes of perioperative right ventricular function after pulmonary resction. Methods 45 cases of pulmonary resection were divided into four groups.Group Ⅰwas wedge resection(n = 10), GroupⅡ was lobectomy(n = 19), Group Ⅲ was double lobectomy(n=7)and Group Ⅳ was pneumonectomy(n=9). The changes of CVP, PAMP, PEP/ET, Sa, VTIs, RVSP, Ea/Aa, and Tel were evaluated by traditional ultrasonic and tissue Doppler ultrasonic techniques at different time inter- vals (pre-operation, 5-7 days orland 1 month post-operation), Results Compared with the pre-operation CVP, the indexes of all groups have no significant changes post-operatively. Wedge resection didn' t obviously influence right cardiac after load and systolic function/diastolic function. No evidet changes detected in Tei pre-and post-operatively. However, the indexes (PAMP, RVSP and PEP/ET ratio) reflecting right cardiac afterload evidently increased at post-pneumonectomy or lobectomy group5- 7 days post-opera- tive. All these reflect the decrease of Tei, which was more obvious in pneumonectomy than in lobectomy group. Right cardiac after- load, systolic/diastolic function and Tel index recovered to pre-operative level 1 month post-operation in single lobectomy group. But the above indicators, especially the Tel, were still high in double lobectomy and pmeunonectomy groups 1 morth post-operation.Tei index is positively correlated with PAMP and is weakly correlated with PET/ET ratio and Ea/Aa ratio. Conclusion Pulmonary wedge resection doesn't evidently influence right cardiac function. However, right cardiac diastolic function evidently decreases temporarily at lobectomy group. The systolic function and diastolic funetions decrease after double-lobectomy and pneumonectomy and it's more evident in pneumonectomy group. Though the right cardiac afterloads of lobectomy, double lobectomy and pneumonectomy groupa all increase significantly post-operativlye, only the former recover to pre-operative level 1 month after surgery.     

经尿道电切与气化切割和激光治疗前列腺增生症的疗效比较

目的 :比较经尿道电切前列腺术 (TURP) ,经尿道前列腺气化切除术 (TUVP)及经尿道接触式激光前列腺切除术 (TULP)的治疗效果。方法 :在 30 0 0例前列腺增生症患者中 ,按三种术式各随机抽取 2 0例术前条件具有可比性的患者 ,进行疗效比较。结果 :3种术式患者手术前后前列腺症状评分 (IPSS)、生活质量评分(QOL)、最大尿流率 (MFR)、剩余尿 (PVR)比较均得到显著改善 (P <0 .0 1) ,3组之间相比差异无显著性意义(P >0 .0 5 )。手术时间 :TUVP及TURP组明显短于TULP组 (P <0 .0 1) ,术中失血量及术后置管时间 :TUVP及TULP组明显少于TURP组 (P <0 .0 1)。TURP组术后继发感染、出血、暂时性尿失禁发生率少于TUVP及TULP组。结论 :3种术式治疗效果相同 ;TUVP操作简单、安全 ,对初学者来说尤其适宜 ;TURP仍为治疗BPH的金标准术式
