男性尿道炎患者多形核白细胞计数与解脲脲原体感染的临床相关性分析

本研究旨在检测男性尿道炎患者中尿道多形核白细胞数量,并进行解脲脲原体(Uu)培养,以评价非淋病奈瑟菌性尿道炎的临床意义。将2284例男性性病患者的尿道分泌物涂片,亚甲蓝(美蓝)染色后镜检多形核白细胞,并体外培养尿道分泌物的Uu。结果显示,645例患者(28.2%)Uu培养阳性,其中158例(24.5%)≥5个多形核白细胞,157例(24.3%)1～4个多形核白细胞,330例(51.2%)无多形核白细胞。218例阳性患者(33.8%)无症状,614例阳性患者(95.2%)无体征。男性尿道多形核白细胞数量在Uu培养阳性和阴性患者中存在显著差异(P0.01)。结果提示临床诊断与实验室检查在证实男性非淋病奈瑟菌性尿道炎中具有重要意义。     

Characterization and mapping of a novel mutant sms1 （senescence and male sterility 1） in rice

Plant senescence plays diverse important roles in development and environmental responses.However,the molecular basis of plant senescence is remained largely unknown.A rice spontaneous mutant with the character of early senescence and male sterility (sms) was found in the breeding line NT10-748.In order to identify the gene SMS1 and the underlying mechanism,we preliminarily analyzed physiological and biochemical phenotypes of the mutant.The mutant contained lower chlorophyll content compared with the wild type control and was severe male sterile with lower pollen viability.Genetic analysis showed that the mutant was controlled by a single recessive gene.By the map-based cloning approach,we fine-mapped SMS1 to a 67 kb region between the markers Z3-4 and Z1-1 on chromosome 8 using 1,074 F2 recessive plants derived from the cross between the mutant sms1 (japonica) × Zhenshan 97 (indica),where no known gene involved in senescence or male sterility has been identified.Therefore the SMS1 gene will be a novel gene that regulates the two developmental processes.The further cloning and functional analysis of the SMS1 gene is under way.

Re-evaluation of the function of the male specific lethal complex in Drosophila

A set of proteins and noncoding RNAs,referred to as the male specific lethal (MSL) complex,is present on the male X chromosome in　Drosophila and has been postulated to be responsible for dosage compensation of this chromosome - the up-regulation of its expression to be　equal to that of two X chromosomes in females.This hypothesis is evaluated in view of lesser known aspects of dosage compensation such as the　fact that metafemales with three X chromosomes also have equal expression to normal females,which would require a down-regulation of each　gene copy.Moreover,when this complex is ectopically expressed in females or specifically targeted to a reporter in males,there is no increase in　expression of the genes or targets with which it is associated.These observations are not consistent with the hypothesis that the MSL complex　conditions dosage compensation.A synthesis is described that can account for these observations.     

衣原体感染不孕不育患者血清中自身抗体的检测

目的:探讨衣原体感染与血清中抗精子抗体(AsAb)、抗心磷脂抗体(ACA)、抗子宫内膜抗体(EMAb)之间的关系.方法:用ELISA法检测120例衣原体感染不育男性(男性衣原体感染组)和55例正常生育男性(男性正常时照组)的血清中AsAb、ACA;检测142例衣原体感染不孕女性(女性衣原体感染组)和60例正常生育女性(女性正常对照组)的血清中AsAb、ACA、EMAb.结果:男、女衣原体感染组AsAb、ACA检出率高于相应对照组,具有显著性差异(P值均＜0.05);女性衣原体感染组EMAb检出率高于女性对照组,具有显著性差异(P＜0.05).结论:生殖道衣原体感染和与不孕不育有着密切的相关性,且AsAb、ACA、EmAb的产生与衣原体感染有关.     

生育与男性的年龄也有较大关系

巴黎艾劳辅助生殖中心的研究人员发现．女性生育与男性的年龄也有较大关系,男性一旦过了不惑之年．会使女性怀孕成功率降低．流产风险增加。他们从1．2万多对夫妇约2．1万例子宫内授精手术中提取精子样本．检查精子质量,并对女方的怀孕、流产和生育率进行了跟踪,结果发现,女方超过35岁,怀孕变难,流产风险增加,这与预料的一样;可令人惊讶的是,男方超过40岁,也会对女方造成类似影响。研究人员说,男方的年龄会影响女方的怀孕成功率,但令他们没想到的是．男方的年龄甚至会影响到女方的流产概率。研究表明,男方超过40岁,女方流产的概率约为35％;男方不到30岁,女方流产的概率约为10％～15％。

老年男性教师骨密度的调查

目的 为了解老年性骨质疏松情况,用超声骨密度仪对150例老年男性教师做跟骨超振幅衰减值的测试研究。方法：用DMS公怀UBIS5000型骨密度超声仪检查跟骨,研究受检者的年龄、体重、身高和巳患病咎与测得超声振幅衰减值（BUA）,声速（SOS）,骨硬度（STI）和相对骨折危险性（RRF）等参数之间的关系。结果：本仪器输出3种结果供医师参考：1.一幅灰阶图,2.一幅彩色图和曲线图,3.感兴趣区所测得的参数,受检者的平均BUA为63.87dB/MHz,SOS为1485.21m/s,本文数据经Statpal软件处理,得出回归公式：体重=189.1417 0.2062BUA-0.0224SOS,R=0.0466,P值有显著意义。结论：BUA值为主要参数,SOS为补充参数,作为评估老年男性教师的骨密度情况,假如BUA值突然下降则提示近期可能发生骨质疏松。
