Asymptomatic seminal infection of herpes simplex virus:impact on male infertility

In more than half of infertile men,the cause of their infertility is unknown.Several studies revealed the role of viral infections in male infertility.The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients,and its association with altered semen parameters.A total of 70 semen samples were collected from infertile men who attended the Research and Clinical Center for Infertility in Yazd,Iran.Semen analysis and diagnostic real-time PCR using specific primers and probes for HSV-1 and HSV-2 DNA were performed.Comparison of semen parameters between virally infected and non-infected samples were performed with independent t-test and Mann-Whitney test.Semen analysis showed that infertile men fell into two groups,the male factor group and the unexplained group.HSV-1 and HSV-2 DNA was detected in 16 (22.9%) and 10 (14.3%) of 70 semen samples,respectively.All HSV-positive samples had abnormal semen parameters (the male factor group).Although HSV infection was not associated with sperm motility and morphological defects,it was correlated with lower sperm count in the seminal fluid.The findings suggest that asymptomatic seminal infection of HSV plays an important role in male infertility by adversely affecting sperm count.

Objective To investigate the expression of DOG-1 in gastrointestinal stromal tumors (GIST)and its diagnostic application.Methods Immunohistochemical EnVision technique was used to assess the expression of DOG-1 in 84 cases of GIST in comparison with CD117 and CD34.Results All 84cases of GIST consisted of variable proportions of spindle and epithelioid tumor cells or iust one type of the tumor cell. The expression rates of DOG-1,CD117 and CD34 were 91.3%(42/46),95.7%(44/46)and 82.6%(38/46),in the group of very low and low risk GIST,and were 100%(38/38),100%(38/38)and 78.9%(30/38),respectively,in the group of moderate and hiish risk GIST. leiomyomas,schwannomas,fibromatosis and normal gastrointestinal mucoca did not express these markers.Moreover, the sensitivity and specificity of DOG-1 in the detection of GIST were similar to those of CD117.without statistical difference(P＞0.05)between the two markers.However,the sensitivity and specificity of DOG-1 detection of moderate and high risk GIsT were significandy higher than those of CD34(P＜0.01).Conclusions DOG-1 is a novel marker of gastrointestinal stromal tumors.It has the sensitivity and specificity hisher than CD34,especially in the detection of moderate and high risk GIST.Combined DOG-1and CD117 immunohistochemistry will likely improve the diagnostic accuracy of GIST.

Examination of Ureaplasma urealyticum and Mycoplasma hominis in 4082 Chinese patients

The objective of this study was to analyze the infection rate and drug resistance of Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) in the genitourinary tract of Chinese patients. From December 2018 to June 2019, vaginal secretion or urinary secretion of outpatients in our hospital were selected for culture and drug sensitivity analysis of Ureaplasma urealyticum and Mycoplasma hominis. In 4082 Chinese samples, 1567 Mycoplasma were detected, a detection rate of 38.39%, among which 1366 cases were UU single positive, accounting for 33.47%, 15 cases were MH single positive, accounting for 0.36%, 186 cases were UU and MH mixed positive, accounting for 4.56%. The most affected age groups were 21-30 years and 31-40 years, accounting for 19.09 and 15.05%, respectively. The results of drug sensitivity showed that doxycycline, minocycline, josamycin, clarithromycin, and roxithromycin were more sensitive to mycoplasma infection. The distribution of Ureaplasma urealyticum and Mycoplasma hominis in the human genitourinary system and their sensitivity to antibiotics is different for sex and age groups.

Antiangiogenic and antitumor effects of 14-membered ring macrolides on mouse B16 melanoma cells

We examined the effects of macrolide antibiotics on tumor angiogenesis, tumor growth and metastasis in the B16BL6 mouse melanoma and C57BL mouse system. Two 14-membered ring macrolide antibiotics, roxithromycin and clarithromycin, significantly reduced the dense capillary network area in a mouse dorsal air sac angiogenesis model, whereas a 15-membered ring macrolide, azithromycin, and a 16-membered ring macrolide, josamycin, did not show any inhibitory effect on angiogenesis at the same dose. Intraperitoneal administration of roxithromycin and clarithromycin at 50 mg/kg/day reduced the tumor size of B16BL6 melanoma to about 41% and 56%, respectively, of that of the control, and significantly suppressed pulmonary metastasis of B16BL6 cells in a spontaneous system. Azithromycin and josamycin, on the other hand, did not inhibit tumor growth or pulmonary metastasis of B16BL6 cells. Immunohistochemistry revealed that roxithromycin and clarithromycin reduced the tumor vascularity and increased apoptosis of the tumor cells in vivo. These results suggest that 14-membered ring macrolides have antiangiogenic and antitumor effects and might have possible therapeutic applications.     

Activity of new macrolides againstBordetella pertussis andBordetella parapertussis

MICs and MBCs of four new macrolides (azithromycin, clarithromycin, dirithromycin and roxithromycin) and two older macrolides (erythromycin and josamycin) forBordetella pertussis andBordetella parapertussis were determined. The activity of the new macrolides was as good as that of erythromycin, while josamycin was slightly less active.Bordetella parapertussis was more resistant thanBordetella pertussis.     

生殖道支原体与女性不孕不育和抗子宫内膜抗体的关系

目的研究女性不孕不育和生殖道解脲支原体（U．urealyticum，UU）、人型支原体（M．hominis，MH）和抗子宫内膜抗体（Antiendometrium antibody，AEMAb）的关系。方法采用培养法分别对108例原发性和96例继发性不孕不育患者宫颈分泌物进行UU，MH检测；采用ELISA检测血清中AEMAb。结果原发性和继发性不孕不育组UU，MH感染率及AEMAb阳性率与对照组比较差异均有显著性（P〈0．00167=。不孕组中支原体感染阳性患者AEMAb阳性率明显高于支原体阴性患者（P〈0．05）。结论女性不孕不育与生殖道支原体感染和AEMAb的产生有密切关系，为临床诊断和合理治疗不孕不育患者提供了理论依据。
