Immunohistochemical analysis of the vimentin filaments in Sertoli cells is a powerful tool for the prediction of spermatogenic dysfunction

The close interaction between male germ cells and Sertoli cells, a type of somatic cell found in the seminiferous tubules of mammalian testis, is essential for the normal progression of spermatogenesis in mammals. Vimentin is an intermediate filament protein that primarily provides mechanical support, preserves cell shape, and maintains the nuclear position, and it is often used as a marker to identify Sertoli cells. Vimentin is known to be involved in many diseases and aging processes; however, how vimentin is related to spermatogenic dysfunction and the associated functional changes is still unclear. In a previous study, we reported that vitamin E deficiency affected the testes, epididymis, and spermatozoa of mice, accelerating the progression of senescence. In this study, we focused on the Sertoli cell marker vimentin and explored the relationship between the cytoskeletal system of Sertoli cells and spermatogenic dysfunction using testis tissue sections that caused male reproductive dysfunction with vitamin E deficiency. The immunohistochemical analysis showed that the proportion of the vimentin-positive area in seminiferous tubule cross-sections was significantly increased in testis tissue sections of the vitamin E-deficient group compared with the proportion in the control group. The histological analysis of testis tissue sections from the vitamin E-deficient group showed that vimentin-positive Sertoli cells were greatly extended from the basement membrane, along with an increased abundance of vimentin. These findings suggest that vimentin may be a potential indicator for detecting spermatogenic dysfunction.     

A Phase 2 open label study of ledipasvir/sofosbuvir for 12 weeks in subjects with hepatitis B virus infection

Retrospective data showed that when we administered ledipasvir/sofosbuvir (LDV/SOF) to patients with hepatitis B and C coinfection, there was a modest reduction in hepatitis B surface antigen (HBsAg). Therefore, we hypothesize that similar HBsAg reduction can be seen in hepatitis B virus (HBV) monoinfected subjects. Primary and secondary efficacy endpoints are the decline in HBsAg and HBV DNA at Week 12 from baseline, respectively. We conducted an open-label Phase 2 pilot study to evaluate the safety, tolerability, and antiviral activity of LDV and/or SOF for HBV. Eligible subjects were either suppressed on antivirals (Group B) or inactive chronic HBV (Group A, C, D). Group A and B received LDV/SOF. Group C and D received SOF 400 mg and LDV 90 mg, respectively. All subjects completed the study, and all related adverse events (AEs) were mild. No discontinuations due to AEs or hepatitis flare occurred. At Week 12, HBsAg decline (log₁₀ IU/ml) was similar between Group A (0.399) and B (0.400), less in Group C (0.207), and none in Group D, and there was HBV DNA decline in the inactive chronic HBV groups. LDV and SOF are safe and well tolerated when given to chronic hepatitis B subjects and have modest antiviral activity, particularly when given in combination.     

幽门螺杆菌与慢性浅表性胃炎患者胃液中sIgA的关系

探讨分泌性免疫球蛋白Ａ在幽门螺杆菌导致的慢性浅表性胃炎中和。方法选取慢性浅表性胃炎患者６３例,按组织学分型分为轻、中、重度胃炎;按有无中性粒细胞的出现分为活动性和非活动性胃炎,采用放射免疫法测定ｓＩｇＡ,ＨＰ检测采用尿素酶试验及Ｗａｒｔｈｉｎ－Ｓｔａｒｒｙ染色。结论ＨＰ是慢性浅表性胃炎的重要致病因素,其致病机制与ｓＩｇＡ保护作用有密切关系。

慢性肾衰患者外源性PGE1与血浆内皮素及降钙素基因相关肽的关系

目的观察外源性前列腺素E1(PGE1)对慢性肾衰(CRF)患者血浆内皮素 (ET)及降钙素基因相关肽(CGRP)水平的影响. 方法利用放射免疫分析法测定9 0例CRF患者经PGE1治疗后的血浆ET及CGRP水平的变化并分析其相互关系. 结果 CRF患者血浆ET的水平较对照组明显升高(P<0.01) ,血浆CGRP的水平较对照组明显降低(P<0.01). ET与肾功能参数 (BUN,Cr)呈明显的正相关(r=0.58 ,P<0.01;r=0.62,P<0.01),与尿量呈明显的负相关(r=-0.60,P< 0.01). PGE1治疗后,ET和CGRP水平均有所好转(P<0.05),同时肾功能参数(BUN, Cr) 和尿量亦有改善(P<0.05). 结论 CRF多伴有血浆ET及CGRP 水平的变化,应用PGE1治疗有益于延缓肾功能的进一步恶化.
