Zishen Yutai Pill improves sperm quality and reduces testicular inflammation in experimental varicocele rats.

ABSTRACT:

Objective

Zishen Yutai Pill (ZYP), containing 15 Chinese traditional medicine, is a safe and well quality-controlled TCM preparation with promising effects in many fields of reproduction. The current study was designed to investigate the therapeutic effects of ZYP on sperm quality and testis in varicocele (VC) rats.

Materials and methods

Male Wistar rats were randomly divided into four groups (n = 6), i.e., a sham group, a VC group, and VC groups treated with different dose of ZYP (1575 and 3150 mg/kg/d, respectively). The experimental VC model was established by partial ligation of left renal vein. Six weeks after model establishment, ZYP was orally administered once a day for the next 6 weeks. Parameters relating to testis and sperm quality were assessed. Hematoxylin-eosin staining was used to showed testicular tissue damage in experimental VC rats. Expressions of proteins relating to NLRP3 inflammasome pathways were determined using Western blot (WB). The mRNA expressions of relating genes were determined using quantitative real-time PCR (qRT-PCR) analysis.

Results

ZYP could significantly improve sperm motility and decrease sperm DNA fragmentation index in VC rats (P < 0.05). Hematoxylin-eosin (HE) staining showed that ZYP could alleviate testicular tissue damage caused by experimental varicocele in rats. Compared to the VC model, expressions of NLRP3, ASC, and caspase-1 in rats treated with ZYP were significantly down-regulated, as validated by both qRT-PCR and WB analysis (P < 0.05).

Conclusions

In brief, ZYP could improve sperm DNA integrity by inhibiting the NLRP3 inflammasome pathway and alleviating the chronic inflammation of testicular tissue induced by experimental varicocele in rats.

Project description:ObjectiveZishen Yutai Pill (ZYP) is a frequently used traditional Chinese medicine (TCM) preparation in women's health. However, the effects of ZYP on endometrial epithelial response have not been fully explored. Herein, uterine natural killer cell (uNK) secretion medium was used to mimic the uterine microenvironment. Thereafter, an endometrial epithelial cell line (Ishikawa cells) was treated with ZYP-containing serum to elucidate the effects of ZYP on endometrial receptivity.Methods: uNK cells were isolated from decidual tissues of pregnant women undergoing pregnancy termination surgery, and thereafter, uNK secretion medium was collected. ZYP-containing serum was collected from rats after intragastrical administration of ZYP. Ishikawa cells were divided into three groups, one treated with blank control (control group), one treated with uNK secretion medium (uNK group), and one treated with both uNK secretion medium and ZYP-containing serum (ZYP + uNK group). Total RNAs were extracted. Gene expression profiles of Ishikawa in different groups were determined through microarray analysis. mRNA expressions of selected genes were determined through quantitative real-time polymerase chain reaction (qRT-PCR). Expression of intercellular cell adhesion molecule-1 (ICAM-1) was determined using Western blotting (WB).ResultsCompared with the uNK group, the gene expressions of ZYP group with a total of 1117 genes were significantly altered, among which 510 genes were upregulated and 607 genes were downregulated. Compared with uNK group, expressions of CSF1, CSF2, SPP1, and ICAM1 were upregulated (P < 0.05). Up-regulation of ICAM-1 expression after treatment of ZYP was further confirmed by WB analysis.ConclusionIn brief, in the presence of uNK cell medium, ZYP could improve the expressions of ICAM1, CSF1, CSF2, TNF, SPP1, etc. However, further exploration should be carried out in in vivo experiments for the validation of the mechanisms of ZYP on endometrial epithelial response.

Project description:Introduction: The current quality evaluation of traditional Chinese medicine (TCM) is difficult to attribute to clinical efficacy due to the complexity of TCM. Zishen Yutai pill (ZYP), a well-known traditional Chinese patent medicine, has been widely used to prevent recurrent miscarriage and treat threatened abortion. However, the chemical components of ZYP are unknown, and there is no convincing quality control method applied on ZYP. Although ZYP has been found to promote endometrial receptivity and treat impending abortion, the substantial basis of the therapeutic effects is unclear. The aim of this study was to clarify the quality markers correlated with the potential medicinal activities and provide a theoretical foundation for scientific quality control and product quality improvement of ZYP. Methods: The chemical constituents of ZYP were comprehensively analyzed by offline two-dimensional liquid chromatography-mass spectrometry (2DLC-LTQ-Orbitrap-MS). The efficacy of the 27 ZYP orthogonal groups was investigated using the HTR-8/SVneo oxidative damage model and migration model in vitro, as well as the endometrial receptivity disorder mouse model and premature ovarian failure mouse model in vivo. Based on the efficacy and mass spectral results, spectrum-effect relationship analysis was used to identify the chemical components with corresponding pharmacological activities. Results: A total of 589 chemical components were found in ZYP, of which 139 were not identified in the literature. The potential quality markers for ZYP were successfully identified through orthogonal design and spectrum-effect relationship analysis. By combining mass spectrum data and pharmacological results of 27 orthogonal groups, 39 substances were identified as potential quality markers. Conclusion: The approaches used in this study will provide a feasible strategy for the discovery of quality markers with bioactivity and further investigation into the quality evaluation of TCM.

Project description:ObjectiveThe purpose of this study was to evaluate the efficacy and safety of Zishen Yutai Pill combined with western medicine for the treatment of women with threatened miscarriage during the first trimester of pregnancy.MethodsRandomized controlled trials published before the end of Apr 1, 2023 on Zishen Yutai Pill and threatened miscarriage were systematically retrieved from China National Knowledge Infrastructure, Wanfang, Sinomed, VIP, PubMed, EMBASE, Web of Science and the Cochrane Library. The international clinical trial registration platform and the Chinese clinical trial registration platform of clinical trials was searched from their inception until Apr 1, 2023. Meta analysis of random effect model was used to combine the research data. Chi-squared test and I2 statistics were used for heterogeneity test.ResultsTwenty-three trials (enrolling 2411 participants) were included in the review. Zishen Yutai pill combined with western medicine therapy showed significant improvement on human chorionic gonadotropin [MD 19.33 IU/ml, 95% CI (15.84, 22.81)], the total effective rate [RR 1.19, 95% CI (1.15-1.23)], progesterone [MD 7.14 ng/ml, 95% CI (6.14, 8.13)], estradiol [MD 33.69 pg/ml, 95% CI (27.42, 39.96)], duration of abdominal pain [MD -2.36 d, 95% CI (- 3.54, - 1.18)], duration of vaginal bleeding [MD -1.94 d, 95% CI (- 2.93, - 0.94)], and fibrinogen [MD -0.34 g/L, 95% CI (- 0.57, - 0.11)]. There was no significant difference in hematocrit [MD 0.68%, 95% CI (- 0.08, 1.44)] between the experimental and the control group. Zishen Yutai Pill may improve the clinical symptoms in women with threatened miscarriage, such as human chorionic gonadotropin the total effective rate, progesterone, estradiol, duration of abdominal pain, duration of vaginal bleeding, and fibrinogen. Especially for progesterone, the effect of treatment ≦2 weeks is significantly better than treatment of >2 weeks. For estradiol, the effect of treatment >2 weeks is significantly better than treatment of ≦ 2 weeks.ConclusionZishen Yutai Pill, as a complementary therapy, significantly improved human chorionic gonadotropin, the total effective rate, progesterone, estradiol, abdominal pain, vaginal bleeding, and fibrinogen in patients with threatened miscarriage in first-trimester pregnancy. However, the systematic review has some limitations, such as degraded information quality, no blinding of patients or doctors, etc. Due to the small sample size and low quality of research, it needs to be further confirmed by large sample and high-quality randomized controlled trials, such as blinding of patients, doctors and outcome assessment should be complemented, clinical follow-up, live birth rate, fetal growth should be supplemented.Systematic review registrationINPLASY202320039.

Project description:PurposeVaricocele has been associated with high seminal oxidative stress (OS), impaired semen quality, and reduced male fertility potential. However, the exact mechanism(s) underlying the development of varicocele-mediated infertility and the cause-effect relationship between varicocele and testicular dysfunction are not fully understood. The aim of this systematic review and meta-analysis (SRMA) is to investigate the impact of varicocele on testicular OS markers and sperm parameters in experimental animals with varicocele as compared to animals without varicocele.Materials and methodsA literature search was performed using the Scopus and PubMed databases on studies that investigated testicular OS markers and sperm parameters in animals with varicocele. The primary outcomes included malondialdehyde (MDA) (nmol/mg) levels whereas the secondary outcomes included total sperm count (×106), sperm vitality (%), total sperm motility (%), and sperm DNA fragmentation (SDF) (%). Standardized mean difference (SMD) (95% confidence interval [CI]) was chosen to express the effect size. The quality of the included studies was evaluated using the Cambridge Quality Checklist.ResultsOut of 76 identified articles, 6 studies on rats were included in the meta-analysis. The analysis showed a significant increase of MDA (SMD: 15.61 [1.93, 29.29]; p=0.03) in rats with varicocele vs. controls. We also observed a significant decrease in total sperm count (SMD: -17.45 [-28.97, -5.93]; p<0.01), sperm vitality (SMD: -16.41 [-26.30, -6.52]; p<0.01), total sperm motility (SMD: -17.67 [-24.90, -10.44]; p<0.01), and a significant increase of SDF (SMD: 7.41 [1.23, 13.59]; p=0.02), in rats with varicocele vs. controls. The quality of the included studies was ranked as high.ConclusionsThis SRMA indicates a significant increase in levels of testicular MDA and SDF and a reduction of sperm quality in experimental animals with varicocele. These findings support the potential role of testicular OS in the development of varicocele-induced testicular damage.

Project description:ObjectiveTo assess the efficacy of the Zishen Yutai Pill compared with placebo on live birth rates among women after fresh embryo transfer cycles.MethodsWe conducted a double-blind, multicenter, placebo-controlled, randomized trial to investigate whether administration of the Zishen Yutai Pill would improve pregnancy outcomes among women undergoing fresh embryo transfer after in vitro fertilization or intracytoplasmic sperm injection. The primary outcome was live birth rate. Secondary outcomes were rates of implantation, biochemical pregnancy, clinical pregnancy, pregnancy loss, cycle cancellation, and maternal, fetal, and neonatal complications. A total sample size of 2,265 women (1:1 in two groups) was used to detect a live birth rate difference between the Zishen Yutai Pill and placebo. Participants were enrolled and randomized to receive 5 g of the Zishen Yutai Pill or placebo orally, three times per day during the study.ResultsRecruitment was completed between April 2014 and June 2017, with 2,580 patients screened. Two thousand two hundred sixty-five patients were randomized: 1,131 to the Zishen Yutai Pill and 1,134 to placebo. Characteristics were similar between groups. In intention-to-treat analysis, the rates of live birth in the Zishen Yutai Pill (ZYP) group and placebo group were 26.8% and 23.0% (rate ratio [RR], 1.16; 95% CI 1.01-1.34; P=.038), respectively. The implantation rates were 36.8% and 32.6% in the ZYP and placebo groups, respectively (RR 1.13; 95% CI 1.01-1.25; P=.027). The biochemical pregnancy rate for the ZYP group was 35.5% compared with 31.1% in the placebo group (RR 1.14; 95% CI 1.02-1.28; P=.026). The rates of clinical pregnancy in the ZYP and placebo groups were 31.2% compared with 27.3%, respectively (RR 1.14; 95% CI 1.00-1.30; P=.043). There were no significant between-group differences in the rates of pregnancy loss, maternal, or neonatal complications (all P>.05).ConclusionThe Zishen Yutai Pill increased the rate of live birth after fresh embryo transfer compared with placebo.Clinical trial registrationChictr.org.cn, Chictr-TRC-14004494.

Project description:BackgroundAs society continues to develop, women are more at risk of gonadotoxic substance exposure. Consequently, the incidence of premature ovarian insufficiency (POI) has increased significantly in the past decades. Hormone replacement therapy (HRT) is recommended as the standard treatment to relieve hypoestrogenic symptoms; however, its potential side effects and contraindications have drawn widespread controversy and concern. As such, the Chinese medicine Zishen Yutai Pill (ZSYTP) commonly used for treating miscarriage and menoxenia, is a highly promising alternative drug candidate against POI, however its therapeutic mechanism has not been completely elucidated.ObjectiveTo systematically analyze the potential therapeutic targets of ZSYTP on POI, we combined network pharmacology analysis and molecular docking to predict critical target genes, with experimental validation on POI murine models.MethodsThe active compounds of ZSYTP were collected from three online databases, and the candidate targets were predicted based on the chemical structure. The POI-related targets were obtained from four databases. A PPI network was constructed to find the key target genes between ZSYTP and POI, while GO and KEGG enrichment analyses were employed to study the mechanism of ZSYTP against POI. The binding capability of the key co-targets with active components was examined by molecular docking. We used a cyclophosphamide (CTX)-inducible POI mouse model to verify our predictions by histopathological observation, immunohistochemical staining (caspase-3, TUNEL assay), hormone determination (FSH, AMH) and ribonucleic acid sequencing (RNA Seq). Progynova was also used to study the difference between ZSYTP and HRT.ResultWe identified 21 target genes as the hub between ZSYTP and POI. The GO and KEGG analyses revealed that the molecular mechanism of ZSYTP against POI were mainly based on the regulation of gene and protein expression. A variety of signaling pathways may be involved in the treatment of ZSYTP against POI, especially PI3K-AKT, HIF-1 and the AGE-RAGE cascades. Docking simulation showed that G1, C1, SR5, and F1 had relatively lower binding energy. In vivo, ZSYTP significantly reversed CTX-induced ovarian damage in follicle number, hormone level and apoptosis, with an overall improved therapeutic effect compared to Progynova. Results from RNA-Seq revealed that the PI3K-AKT, Hippo, AGE-RAGE, and Rap1 signaling pathways and regulation of inflammation, immune response, and lipid metabolism may mediate the protective effects of ZSYTP against POI, which is different than Progynova's mechanism of action.ConclusionsCollectively, this study indicates that ZSYTP could be a highly promising alternative as a non-HRT-based therapy for POI. Its mechanism involves multiple signaling pathways, alleviating ovarian apoptosis and recovering AMH and FSH level. However, the discrepancy between different research techniques highlight the necessity of further experimental verification from other aspects such as translation and posttranslational modification.
