Abstract:
ObjectiveTo observe the effects of Baihe Yuzi prescription （BYP） on the cystic fibrosis transmembrane conductance regulator （CFTR）， aquaporin （AQP）， zinc/iron-regulated transporter-like protein （ZIP） and local oxidative stress in epididymis of oligoasthenozoospermia （OAS） rats， and to explore the mechanism of its intervention in OAS. MethodAfter 35 rats were acclimatized for 1 week， 7 rats were randomly selected as the normal group， and the remaining 28 rats were given tripterygium glycosides （TG） 30 mg·kg-1. After 4 weeks of modeling， they were randomly divided into 4 groups： model group， BYP low-dose group （LBYP）， BYP high-dose group （HBYP） and levocarnitine group， with 7 rats in each group. The rats in the normal group and model group were given normal saline at the same dosage. The levocarnitine group rats were given L-carnitine oral liquid （100 mg·kg-1） by gavage. The LBYP group rats were given BYP 6.3 g·kg-1， and the HBYP group rats were given BYP 12.6 g·kg-1 by gavage once a day for consecutive 4 weeks. After the end of the intervention， sperm count and motility of all rats were detected， the histopathological structure of epididymis was observed by hematoxylin-eosin （HE） staining， and the expressions of CFTR， AQP9， AQP3， ZIP8， ZIP12 and other proteins were detected by Western blot. The contents of α-glycosidase （α-GC）， sialic acid （SA）， carnitine， superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px） and malondialdehyde （MDA） were detected by enzyme-linked immunosorbent assay （ELISA）. Total zinc content was measured using an inductively coupled plasma mass spectrometer. Free zinc ion content was detected by zinc ion probes. ResultCompared with those in the normal group， the sperm count and motility of rats were decreased and the epididymal structure was disordered in the model group. The contents of α-GC and carnitine were decreased in epididymis （P<0.05）. MDA levels were increased， while SOD， GSH-Px and zinc levels were decreased （P<0.05）. The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were down-regulated， and AQP3 expression was up-regulated. The expression of ZIP8 in the cauda epididymis was up-regulated （P<0.05）. Compared with the model group， BYP can significantly improve the sperm count and motility， the epididymal structure of OAS rats and the levels of α-GC and carnitine （P<0.05）. The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were up-regulated， while the expressions of ZIP8 in the cauda epididymis and AQP3 in the head of the epididymis were decreased （P<0.05）. The SOD and GSH-Px levels and total zinc content in epididymis were increased， and the MDA levels were decreased （P<0.05）. ConclusionBYP may improve the sperm quality and repair epididymal tissue structure and function of OAS rats， by regulating the expressions of CFTR， AQP3， and ZIP12 ion channels and local antioxidant mechanism.
