Male infertility affects millions of males worldwide and is rising in prevalence due to social and environmental conditions. Asthenozoospermia (AZS) and oligoasthenozoospermia (OA) are the major causes of male infertility. The diagnosis of male infertility has a negative effect on men's physical and psychological status, poses a threat to their social relationships, lowers self-esteem, and disrupts family harmony. At present, the treatment of ASZ and OA are all mostly empirical, including antioxidants, endocrine therapy, and anti-infection. However, there are still limitations due to inefficiencies. Linggui Yangyuan paste (LGYY), a traditional Chinese compound herbal past, had been used to treat ASZ and OA for several years at the Xiyuan Hospital of China Academy of Chinese Medical Sciences. The investigators designed this program to study the efficacy and safety of LGYY for the treatment of patients with male infertility (AZS and OA).

Decoction of Yougui Wan combined with Wuzi Yanzong Wan ameliorates thin endometrium in a mouse model

Article

Author: Zhou, Xiaohong ; Su, Aifang ; Xiang, Jun

BACKGROUNDThis study aimed to determine the effect and mechanism of the Decoction of Yougui Wan combined with Wuzi Yanzong Wan (DYWWYW), a traditional Chinese herbal formula, in a mouse model with thin endometrium induced by 95% ethanol.METHODSThin endometrium mice were treated with progynova (0.002 mg) as well as a low and high dose of DYWWYW (0.05 and 0.5 mL DYWWYW, respectively, diluted in 2 mL normal saline). Western blotting and qRT-PCR analyses were performed to determine the protein and mRNA expression levels, respectively, of integrin αγβ3 and leukaemia inhibitor factor (LIF) in uterus tissues. Serum oestradiol and progesterone concentrations were determined via ELISA. The remaining thin endometrium mice were mated with male mice, and the number of embryos implanted in the different groups was calculated.RESULTSA high dose of DYWWYW effectively ameliorated the injury of endometrium caused by 95% ethanol. The levels of oestradiol, progesterone, αγβ3 and LIF in thin endometrium mice treated with a high dose of DYWWYW were also significantly elevated. Additionally, a high dose of DYWWYW remarkably increased the number of embryo implantations in mice with thin endometrium.CONCLUSIONDYWWYW has improvement effects on thin endometrium by elevating the levels of endogenous oestradiol, progesterone, αγβ3, and LIF in a mouse model.

ETHNOPHARMACOLOGICAL RELEVANCEWuzi Yanzong Prescription (WZ), a classic traditional Chinese medicine formula, has the properties of kidney nourishing and essence strengthening, and it is widely used to treat male infertility with a long history. Sertoli cells are injured with aging, resulting in testicular dysfunction, and WZ effectively rejuvenates the age-related decline of testicular function. However, whether the therapeutic effects of WZ on aging-related testicular dysfunction are dependent on the restoration of Sertoli cell function remains unclear.AIM OF THE STUDYIn a mouse model of natural aging, we explored the protective effects of WZ and its potential mechanisms.MATERIALS AND METHODSFifteen-month-old C57BL/6 mice were randomized to receive either standard diet or WZ (2 and 8 g/kg) for 3 months. Meanwhile, 10 1-month-old mice were considered the adult control group and received standard diet for 3 months. The testis and epididymis were rapidly collected, and the sperm quality, testicular histology, Sertoli cell numbers, tight junction (TJ) ultrastructure, and blood-testis barrier-associated protein expression and localization were assessed.RESULTSWZ significantly increased sperm concentration and sperm viability, improved the degenerative histomorphology and elevated the seminiferous epithelium height. Furthermore, WZ increased the number of Sertoli cells, restored the ultrastructure of the Sertoli cell TJ, and upregulated the expression of TJ-associated proteins (zonula occludens-1 and Claudin11), ectoplasm specialized-associated proteins (N-Cadherin, E-Cadherin and β-Catenin), and gap junction-associated protein (connexin 43), but did not affect the expression of Occludin and cytoskeletal protein (Vimentin). In addition, WZ did not change the localization of zonula occludens-1 and β-Catenin in aged testis. Moreover, WZ increased the expression of autophagy-associated proteins (light chain 3 beta and autophagy related 5) and decreased the expression of p62, phosphorylated mammalian target of rapamycin, and phosphorylated AKT in Sertoli cells. Finally, we found that WZ attenuated mTOR complex 1 (mTORC1) activity and upregulated mTORC2 activity, as evidenced by inhibition of the expression of the regulatory-associated protein of mTOR, phosphorylated p70 S6K, and phosphorylated ribosomal protein s6 and enhancement of the expression of Rictor in the Sertoli cells of aging mice.CONCLUSIONSWZ improves the injury of Sertoli cells by restoring AKT/mTOR-mediated autophagy and the mTORC1-mTROC2 balance in Sertoli cells during aging. Our findings provide a new mechanism of WZ in the treatment of aging-induced testicular dysfunction.

Parkinson disease (PD) is an age-related neurodegenerative disease, which is associated with the loss of dopaminergic neurons (DA neurons) in the substantia nigra pars compacta (SNpc), and neuroinflammation may lead to the occurrence of PD. Wuzi Yanzong Pill (WYP) has demonstrated neuroprotective and anti-inflammatory properties, but its molecular mechanism of action is still unclear. In this study, we used 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mice and LPS-mediated BV2 microglia to explore WYP intervention, anti-inflammatory effect and molecular mechanism in vivo and in vitro. The results showed that oral administration of WYP in MPTP-induced PD mice for 2 weeks ameliorated abnormal motor dysfunction, attenuated the loss of TH + neurons in SNpc, protected dopaminergic neurons, and inhibited the activation of microglia in MPTP-induced PD mice and LPS-stimulated BV2 cell. Meanwhile, WYP intervention inhibited the expression of IL-6, TNF-α, Pro-IL-1β, IL-1β, Pro-IL-18, IL-18 and enhanced the expression of IL-10 in the SNpc of PD mice. Simultaneously, WYP intervention inhibited the expression of NLRP3 inflammasome, accompanied by the decrease of the TLR4/MyD88/NF-κB pathway. However, the exact target and interaction of WYP on NLRP3 inflammasome and TLR4/MyD88/NF-κB pathway still needs to be further investigated.
