男性不育症患者的精液各项参数与解脲支原体感染相关性分析

目的:探讨男性不育患者解脲支原体感染与精子各项参数的关系。方法:收集103例不育男性患者,检测解脲支原体感染情况以及精液pH值、液化时间、精液的体积、精子密度、活力和正常形态率,并按照是否感染解脲支原体分为阳性组和阴性组,比较两组精液的各项参数的差异是否有统计学意义。结果:与解脲支原体感染阴性组比较,阳性组的患者的精液密度、活力和正常形态率显著降低,精液液化时间显著增长(P0.05),而两组患者的精液的pH值和精液体积的比较没有统计学意义。结论:解脲支原体感染会影响精液液化时间、精子浓度、活力和正常形态率,是导致男性不育的重要原因,应引起临床医生和孕前检查的夫妇们的关注。     

补肾生精饮联合穴位针灸改善精子质量提高夫精人工授精应用率的临床研究

目的:为提高夫精人工授精应用率,观察补肾生精饮联合穴位针灸治疗轻中度少弱精患者的精子质量的疗效及安全性。方法:对由于轻中度少弱精子症引起男性不育患者给予口服补肾生精饮联合穴位针灸治疗24周,并分别于治疗前以及治疗后第3、6、9、12、18、24周检测精液参数并进行精液预处理。结果:132例患者,有12例中途退出,治疗过程中女方临床妊娠8例(6.67%),达到人工授精指标56例(46.67%)。与治疗前相比,在补肾生精饮联合穴位针炙治疗后,精子密度、精子活力、(a+b)级精子总数以及精液预处理后(a+b)级精子总数在治疗过程中均有逐渐增高趋势,其中精子密度在治疗9周后各时间组显著性增高(P0.05),精子活力即(a+b)级精子百分率、(a+b)级精子总数以及精液预处理后(a+b)级精子总数在治疗第12周后各时间组显著增高(P0.05)。结论:补肾生精饮配合针灸治疗能够改善轻中度少弱精患者的精子质量,提高夫精人工授精的临床应用率。     

睾丸生精细胞凋亡的基因调控

睾丸生精细胞的增殖、分化受到严格的基因调控,同时在精子发生的生理和病理过程充当着重要角色。生精细胞凋亡是机体清除剩余或缺陷细胞的正常生理机理,也可能是男性不育的病理环节。寻找影响生精细胞凋亡的调节因子,阐明各种死亡信号的调控机制,掌握生精细胞凋亡的病理学调控,将为男科不育的治疗及探索男性节育新途径奠定理论基础,为睾丸精液脱落细胞学的检测,评价睾丸生殖功能与性功能提供了依据。     

70例无精子症生精细胞检出与病因分析

目的:根据精液中生精细胞的有无、形态和比例,进行精象分析,作为评价睾丸功能和鉴别阻塞性和非阻塞性无精子症的有效方法.方法:用精液涂片,瑞-吉氏染色,油镜下分类和分型,并以睾丸活检病理所见对照.结果:697例不育者中发现70例无精子,检出率为10.04%,有生精细胞者42例(60%),95.2%有精母细胞和精子细胞;无生精细胞者28例(40%),两者的睾丸大小显著不同.病因以服用过棉籽油占30.00%;原因不明占22.86%;腮腺炎史占12.86%;输精管因素占10.00%.精液细胞学检查与睾丸活检病理诊断基本一致.结论:精液细胞学检查是一种无创伤性、无后遗症、无痛苦和操作简便,适用于基层判断睾丸功能和区别病因的有效的方法,值得推广.     

“化浊育精颗粒”治疗精子DNA损伤男性不育患者临床观察

目的观察"化浊育精颗粒"治疗精子DNA损伤男性不育患者的作用。方法选择120例合并有精子DNA完整性异常的男性不育患者,将其随机分为治疗组和对照组,每组60例患者。治疗组患者口服"化浊育精颗粒",对照组患者口服左卡尼汀口服液,治疗周期均为3个月。治疗前和治疗后,采用计算机辅助精子分析系统与流式细胞仪分别检测两组患者精液常规参数和精子DNA碎片化指数(DNA fragmentation index,DFI)。结果治疗前,两组患者DFI差异无统计学意义(P0.05);治疗前后,两组患者精子DFI改善比较,其差异均具有统计学意义(均P0.05);治疗后,治疗组患者精子DFI均值(19.5±2.2)低于对照组患者(24.2±4.3),其差异具有统计学意义(P0.05);两组患者对精子DFI疗效差异具有统计学意义(P0.05)。结论对于精子DNA损伤男性不育,"化浊育精颗粒"和左卡尼汀口服液均可以降低精子DFI,但"化浊育精颗粒"对减轻精子DNA损伤具有更好的疗效。     

解脲支原体及抗精子抗体对不育男性精液参数的影响分析

目的：分析男性不育症患者精液中解脲支原体（UU）和抗精子抗体（AsAb）对精液参数的影响,并探讨精液AsAb和UU感染的关系。方法：收集男性不育症患者283例,采用计算机辅助分析系统行精液常规分析（CASA）,用DNA体外扩增原位杂交术（PCR）检测精液UU,采用混合抗球蛋白反应试验（mixed antiglobulin reaction,MAR）检测精液AsAb。结果：UU 和AsAb 阳性组精子活力均较UU 和AsAb 阴性组下降,而两组之间精子密度无显著差异。AsAb阳性组中UU阳性率显著高于AsAb阴性组。UU阳性组经敏感抗生素治疗后精子活力显著改善,AsAb阳性率显著下降。讨论：UU和AsAb对精子运动主要参数有明显影响,是导致男性不育的重要因素,而UU是产生AsAb的重要原因之一。     

从3例诊疗报告看精子形态学与生精细胞学检测在男科临床中的应用

近年来,精子形态学和生精细胞学检测越来越受到男科特别是生殖中心的重视,然而将未染色的精液进行形态学和细胞学分析,其对精子的畸形率及圆细胞的判断存在极大的误差。笔者通过将3例典型患者的精液染色后分析精子形态和生精细胞,做出新的病情诊断及治疗方案,从而探讨精子细胞学与生精细胞学检测在男科临床中的应用价值。

Botulinum toxin A in the treatment of the wrinkles in the upper third of the face

The practice of botulinum toxin injections is unavoidable in the correction of facial aging. In effect botulinum toxin allows to erase dynamic wrinkles, by transient and reversible muscular relaxation. This is the best wrinkle treatment for the upper part of the face: glabellar lines, horizontal forehead lines and crow's feet. This technique requires a good understanding of facial muscular anatomy, in order to correctly apply the basics of injection. Every patient is unique and only a big experience will allow to refine and personalise injections.     

Changes in the T-wave of the electrocardiograph in urticaria

A series of cases is presented, in which non-specific primary changes in the T-waves were observed in electrocardiographs of patients with urticaria, the latter caused by drugs or other substances. In all these patients, no other abnormality was found and they were completely asymptomatic as regards cardiac involvement. A definite ‘cause and effect’ type of relationship was found between the T-wave changes and the urticaria. The mechanism of the T-wave changes remains to be investigated. Since this phenomenon disappears simultaneously with the urticaria, treatment should be determined by the urticaria, and bed rest is not indicated.     

Ultrastructure of the Fibrous Substance in the Keratinocytes of the Epidermis in Healthy Individuals

The present findings in the epidermis of healthy individuals suggest that the fibrous substance in the keratinocytes is subjected to an individual differentiation as the cells move from stratum basale through strata spinosum and intermedium to stratum coreum. In the basal cells the fibrous substance consists of opaque tonofilaments, mostly aggregated in dense tonofibrils, but also occurring randomly scattered and in loose tonofibrils (fibrous substance of basal-cell type). In most cells the fibrous substance undergoes differentiation: a) in stratum spinosum into compact tonofibrils with no individual tonofilaments visible (fibrous substance of spinous-cell type), b) in stratum inter-medium into compact tonofibrils with intensely stained regions or keratohyalin (fibrous substance of intermediate-cell type), and c) in stratum corneum into tonofibrils with a keratin pattern (fibrous substance of horny-cell type). There are also keratinocytes in which the fibrous substance undergoes only an incomplete differentiation, with the appearance of horny cells with a fibrous substance of spinous-cell type, intermediate-cell type or horny-cell type with keratohyalin. Finally, there are keratinocytes in which the fibrous substance does not undergo any differentiation at all, but which display a fibrous substance of basal-cell type throughout the entire epidermis.     

Experience in the use of ditrastic in the therapy of psoriasis

Forty-six patients suffering from psoriasis have been treated with ditrastic, a new drug for external application, manufactured by Orion, Finland. The drug is manufactured in the form of sticks weighing 2.4 g, containing 1.5 or 3% of dithranol, paraffin, and microcrystalline sulfur. These sticks are applied to psoriatic plaques once daily. The treatment has been effective.
