肾盏切开联合经肾实质气压弹道碎石治疗复杂鹿角形结石

目的探讨肾盏切开联合经肾实质气压弹道碎石治疗复杂鹿角形结石的疗效。方法电刀切开积水较重的肾盏,气压弹道碎石杆对准结石碎石后分块取出。盏颈口狭窄但肾盏积水不严重者,将直径1 mm气压弹道碎石杆于肾实质处刺入结石位置,将肾盏内结石击碎后从盏颈口取出。结果19例均未阻断肾蒂,手术时间90-150 min,平均120 min。术中出血量100-250 ml,未输血。17例一次取石成功,术后无结石残余;1例术中残余泥沙状结石,术后经肾造瘘管冲洗引流排出;1例肾盏结石术中取石遗漏,术后经ESWL碎石后排净结石。15例随访10-60个月,平均18个月,结石复发2例,体外震波碎石后排净结石。结论肾盏切开联合经肾实质气压弹道碎石治疗复杂性鹿角形结石出血少,疗效可靠。

Mouse chromosome 9 quantitative trait loci for soft tissue regeneration: Congenic analysis and fine mapping

Development of gene therapies for wound healing will depend on the identification of the genes involved in wound healing and tissue regeneration. Previous quantitative trait loci (QTL) studies in mice using the ear punch model have shown that major QTL exist on chromosome (Chr) 9 for soft tissue regeneration. In this study, we have developed a congenic line that contains the Chr 9 QTL chromosomal region from super healer MRL/MpJ in the genomic background of poor-healing SJL/J. The phenotypic effect of this QTL was confirmed in male mice, where the congenic line has shown significant healing improvement over SJL. Fine mapping of the Chr 9 QTL region with 23 markers at an average distance of 4.2 Mb using a total of 1,564 MRL/MpJ x SJL/J F(2) mice revealed the presence of at least three QTL peaks, implying that three separate loci may contribute to the phenotypic effect of this QTL. Based on the 2-LOD intervals, the total QTL region was confined to a combined length of no more than 28.2 Mb. Application of a Bayesian shrinkage estimation indicated that a major locus was located in a region of just 1.3 Mb.     

焦虑症共病抑郁症状在门诊患者中的调查研究

目的调查门诊患者中焦虑症的患病率以及共病抑郁症状的发生率。方法在我院精神科门诊、心理咨询门诊以及社区卫生服务中心内科门诊就诊的1106例患者作为研究对象，并做SAS、SDS、HAMA量表评定。结果1106例患者中，符合焦虑症诊断，且HAMA≥14分者共93例，患病率为8.41%。SDS标准分≥50共病抑郁症状的共43例，占46.23%。HAMA分值、SAS分值与SDS分值有显著性正相关。结论门诊中罹患焦虑症的患者焦虑程度越高，共病抑郁的可能性就越大。     

经尿道切除技术在下尿路疾病中的应用（附128例报告）

目的 探讨经尿道切除技术（TUR）治疗下尿路疾病的适应证、操作方法、术中术后处理及并发症预防的要点。方法 应用经尿道汽化电切术（TURVP）和双极等离子汽化电切术（TUPKVP），分别以5％葡萄糖液和生理盐水作冲洗介质，选择性耻骨上膀胱造瘘，持续低压灌洗，术后气囊导尿管留置5～7天拔管，自行排尿。结果 经尿道前列腺双极等离子汽化电切术7例，经尿道前列腺汽化电切术58例，合计前列腺手术65例；腺性膀胱炎汽化电切术43例；膀胱肿瘤汽化电切术15例；后尿道狭窄等离子汽化电切术3例；精阜腺瘤汽化电切术2例。全部病例均一次手术完成，有效率（126／128）98．4％。无膀胱穿孔、电切综合征、大出血、真性尿失禁发生。前列腺术后尿道狭窄、排尿困难再次手术者2例，占3．08％，排尿疼痛、不适感6例，占9．23％，逆行射精4例，占6．15％。结论 TUR技术是一种微创、安全、迅速、有效、恢复快、并发症较少的腔内泌尿外科治疗方法，特别适用于下尿路疾病的手术；术中持续低压灌注对确保切割视野清晰、预防并发症至关重要。     

The correlation between TNF-α, IL-6 in cervical mucous during follicular development and ovulation stimulation in different protocols

Objective To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods 36 infertile women were set up as experimental groups,divided into CC, HMG, IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase, luteal phase and ovulation phase were collected.TNF-α, IL-6 levels in cervical mucous were measured by radioimmunology assay (RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results (1) TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase, reached to peak during ovulation phase, and decreased during luteal phase (P＜0.05).IL-6 levels had no obvious periodical changes.(2) Compared with CC and control group, levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher (P＜0.05).(3) Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter (r=0.261, r=0.192 respectively,P＜0.05).(4) TNF-α and IL-6 showed positive correlation in the reproductive cycle (r=0.782,P＜0.05).Conclusions (1) TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2) TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4) TNF-α and IL-6 may have coordination properties and participate in the same biological effects.
