Chromosomal Rearrangements in Three Infertile Men

Summary:  Three chromosomal rearrangements: a balanced reciprocal translocation, t(14;10) (q22;q13), a Y-autosome translocation, t(Y;16) (q11;p13) and a deleted Y chromosome, Yq- were detected among 100 infertile men. The autosomal translocation, associated with oligozoospermia was found to be familial with various effects on the female carriers and the proband's father. The patients with the chromosome Y abberations were found to be azoospermic and might have lost the genes necessary for normal sperma-togenesis.
Zusammenfassung:  Unter 100 infertilen Männern wurden drei Chromosomenneuan-ordnungen entdeckt: eine balancierte reziproke Translokation, t(14;10) (q22;q13), eine Y-autosome Translokation, t(Y;16) (q11;p13) und eine Deletion des Y-Chromosoms, Yq-. Die autosomale Translokation bei Oligozoospermie zeigte sich familiär mit verschiedenen Auswirkungen bei den weiblichen Überträgern und dem Vater des Probanden. Die Patien-ten mit chromosomalen Y-Aberrational wiesen eine Azoospermie auf und scheinen die zur normalen Spermatogenese notwendigen Gene verloren zu haben.     

Sperm chromatin integrity in young men with no experiences of infertility and men from idiopathic infertility couples

Damage to the genetic component of spermatozoa seems to play the main role in a majority of cases where current approaches fail to reveal the specific cause of male infertility. In this study, we compared semen quality in men assigned to two defined groups: men from couples with unexplained infertility – idiopathic infertility (A) and young men with no experiences of infertility (B). All samples were examined by standard ejaculate analysis and sperm chromatin structure assay (SCSA). Sperm chromatin damage was significantly higher in men from group A than in those from group B. Similar results were obtained by comparison of men from group A (all men were normozoospermic) with normozoospermic men from group B. According to these results, we can suppose that chromatin disorders may be the causal factor of subfertility or infertility in some of these men. No evidence for a strong association between chromatin disorders and standard parameters of ejaculates was found. We failed to confirm a relationship between smoking and sperm quality in men from any of the investigated groups. SCSA is a method that facilitates the identification of infertile men who otherwise show normal semen variables.     

对诊断PADAM的游离睾酮指数的评估

目的 评价诊断中老年男子部分雄激素缺乏综合征（PADAM）的游离睾酮指数（FTI）.方法 对129例45岁以上健康男性的FTI进行年龄相关分析.以推算的游离睾酮（CFT）值为依据,对FTI进行有效性检验.结果 男子在中老年期FTI与增龄呈明显的负相关.FTI敏感性97.78%,特异性58.33%.结论 计算简单的FTI可用于PADAM病人的筛选和随访,尤其对70岁以上男子是血清FT较为有效的参数.     

132例男性不育患者遗传学病因分析

目的：对男性不育患者进行遗传学病因分析，并探讨其遗传效应。方法：采取132例男性不育患者外周血进行染色体核型分析。结果：132例男性不育患者中，染色体异常24例，染色体变异22例。其中大Y20例，47，XXY18例，45．XY，t(13；14)3例，小Y和46，XY，inv(9)各2例，46，XY，t(9；22)1例。结论：染色体异常是男性不育的重要原因，并建议男性不育患者进行基因诊断，以便确诊是否属于遗传病，为生育提供指导，避免盲目治疗。     

男性病人冠状动脉病变与吸烟关系的研究

[目的]探讨吸烟对病人冠状动脉病变的影响。[方法]对吸烟组(5 0例)与不吸烟组(3 0例)进行冠状动脉造影,观察记录冠状动脉病变情况并进行统计学分析。[结果]两组冠状动脉病变记分、每日不同吸烟量与冠状动脉病变记分、不同的吸烟年限与冠状动脉病变记分比较均有统计学意义(P <0 .0 1)。[结论]长期吸烟可使冠状动脉病变程度加重,应加强对长期吸烟及冠状动脉介入术后病人的健康教育,有效预防和控制冠心病,提高人群的健康水平。     

Reassessment of the accuracy of traditional sperm characteristics and adenosine triphosphate (ATP) in estimating the fertilizing potential of human semen in vivo

Receiver operating characteristic curves and accuracy parameters were computed for traditional sperm characteristics (concentration, motility, morphology) and the number of peroxidase negative cells, and the concentration of adenosine triphosphate (ATP) in semen from populations of fertile and infertile men, and men who achieved a pregnancy after varicocele treatment. The percentage and concentration per millilitre of spermatozoa with rapid linear progressive motility, and the ATP concentration, provided the best discrimination between fertile and treated fertile from infertile men. The misclassification rate was higher for sperm morphology, total progressive motility and viability, whereas sperm concentration and the total sperm count per ejaculate had the worst discriminating power. The number of peroxidase negative cells per 100 spermatozoa was highly specific in identifying men who achieved pregnancy after varicocele treatment. The lower limit of normality of sperm characteristics was remarkably different between fertile men and men achieving pregnancy after treatment or during infertility work-up.     

老年男性心肌缺血患者心率变异分析（附67例报告）

采用正常搏动ＲＲ间期的标准差（ＳＤ）及心率变异指数（ＨＲＶ ｉｎｄｅｘ）作为指标，分析６７例老年男性心肌缺血患者的心率变异，并与正常老年男性组及正常青壮年男性组进行了对比，发现前组的ＲＲ间期ＳＤ、ＨＲＶｉｎｄｅｘ均明显低于后两组，其结果有显著性差异（Ｐ均〈０．０１）。提示心肌缺血可破坏交感与迷走神经的均衡性，造成心率变异降低。     

Endocrinology: High incidence of embryo transfer cancellations in patients with polycystic ovarian syndrome

This study was aimed at assessing the outcome of in-vitro fertilization(IVF) and embryo transfer in patients with polycystic ovariansyndrome (PCOS). The results of IVF and embryo transfer in PCOSpatients (PCOS group, 78 cycles of 26 patients) were comparedwith those of a control group (423 cycles in 202 patients withoutmale factor; age and ovarian stimulation protocol were matched).Although the pregnancy rate per transfer was not different inthe two groups of patients (25 versus 34%, PCOS versus controlgroup), the PCOS group had a significantly lower pregnancy rateper follicle aspiration (19 versus 31%, P < 0.05). A notableresult was a significantly higher incidence of embryo transfercancellations in the PCOS group (22 versus 8%, P < 0.01),which resulted from unpredictable failure of either oocyte recoveryor fertilization. The incidence of unexplained complete failureof fertilization was significantly higher in the PCOS group(18 versus 5%, P < 0.01). These results may reflect a reducedquality of the oocytes in the PCOS group, and there was a subgroupof PCOS patients who repeatedly produced poor results of treatment.Although the ovarian stimulation regimen best suited to PCOSpatients remains to be determined, special care should be takenduring ovarian stimulation, especially when the PCOS patientshad experienced unexplained failure of oocyte recovery or fertilizationin the previous treatment cycle(s).
