Jujing Zhuyu decoction inhibits apoptosis in rats with asthenozoospermia by regulating the mitochondrial apoptosis pathway.

Jujing Zhuyu decoction (JZD) is a traditional Chinese medicine that effectively improves sperm motility. However, the molecular mechanism of JZD on asthenozoospermia still remains unknown. In this study, we investigated the effect of JZD on the mitochondrial apoptosis pathway in an asthenozoospermia rat model. Sixty Sprague-Dawley rats were randomly divided into five groups-control, tripterygium glycosides (GTW) model, JZD-low (JZD-L), JZD-medium (JZD-M), and JZD-high (JZD-H) groups (n = 12/group). GTW was used to generate the asthenozoospermia model. The JZD-L, JZD-M, and JZD-H groups were administered 5, 10, or 15 g kg-1  day-1 of JZD granules respectively, for 4 weeks. Testicular tissue morphology was examined using histological staining, while sperm count was determined using manual and computer-aided semen analyses. Apoptosis of spermatogenic cells was detected with the TUNEL assay, and the expression of proteins and genes related to mitochondrial apoptosis was detected using western blotting and quantitative reverse transcription-polymerase chain reaction respectively. Histomorphological evaluation revealed superior seminiferous tubule structure and arrangement as well as improved spermatogenic cell morphology in the JZD-L, JZD-M, and JZD-H groups compared to those in the model group. Moreover, semen quality and the apoptotic index were significantly improved in the JZD-L, JZD-M, and JZD-H groups compared to those in the model group. Additionally, the mRNA expression and protein abundance of Apaf-1, Bax, Cyto-c, and caspase-3 was reduced, while those of Bcl-2 were increased in all JZD groups compared to those in the model group. JZD reduces the apoptosis rate of sperm cells and significantly promotes sperm survival by regulating the mitochondrial apoptosis pathway. This mechanism provides experimental support for the treatment of asthenozoospermia by JZD.

Effectiveness and safety of acupuncture combined with traditional Chinese medicine in the treatment of chronic prostatitis: A systematic review and meta-analysis.

OBJECTIVE: Chronic prostatitis (CP) is a common disease in the outpatient department of males and urology. Clinical studies have found that acupuncture combined with traditional Chinese medicine (TCM) has achieved good results in treating CP, but its efficacy and safety are not completely clear. This study aimed to investigate the efficacy and safety of acupuncture combined with TCM in the treatment of CP. METHODS: Randomized controlled trials of acupuncture combined with TCM in treating CP were screened by searching PubMed, Embase, Cochrane Library, CNKI, etc. The retrieval time was from the database establishment date to March 31, 2021. The Cochrane Collaborative Risk Bias Assessment tool was used to evaluate literature's methodological quality of the literature. The RevMan5.4 software was used for the meta-analysis of outcome indicators. The TSA v0.9 software was used for sequential trial analysis (TSA) of effectiveness. RESULTS: In this study, 19 related randomized controlled trial studies were included, with a total of 1831 cases. The results of the meta-analysis showed that acupuncture combined with TCM could significantly improve the clinical efficacy of CP (OR = 3.76, 95%CI: 2.82 to 5.02, P < .00001), reduce the total score of The National Institutes of Health chronic prostatitis symptom index (MD = -4.00, 95%CI: -4.67 to 3.33, P < .00001), and improve patients' urination symptoms (MD = -1.10, 95%CI: -1.23 to -0.97, P < .00001), alleviated the pain symptoms of patients (MD = -2.38, 95%CI: -2.41 to -2.35, P < .00001), improved the quality of life of patients (MD = -1.69, 95%CI: -1.97 to -1.41, P < .00001), decreased the scores of TCM symptoms of patients (MD = -2.39, 95%CI: -3.45 to -1.33, P < .00001), and did not increase the adverse reactions of patients (MD = 1.09, 95%CI: 0.57 to 2.06, P = .8). The results of publication bias showed that this study was not affected by publication bias, and the conclusion was reliable. TSA showed that acupuncture combined with TCM was effective in treating CP. CONCLUSION: Acupuncture combined with TCM is safe and effective for alleviating CP. It can be used as an effective treatment for chronic prostatitis in the clinic.Registration number: DOI 10.17605/OSF.IO/Z8FJM.

The effectiveness and safety of traditional Chinese herbal medicine for the treatment of male infertility associated with sperm DNA fragmentation: A protocol for systematic review and meta-analysis.

BACKGROUND: Sperm DNA fragmentation (SDF) may hinder embryonic development and growth, increasing the risk of spontaneous miscarriage, and is considered an important factor affecting male infertility (MI). Traditional Chinese herbal medicine is considered effective in the treatment of MI due to SDF by nourishing kidney essence or promoting blood circulation for removing blood stasis. The objective of this systematic review protocol is to evaluate the effectiveness and safety of traditional Chinese herbal medicine on the treatment of MI associated with SDF. METHODS: We searched the PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP Chinese Science, Technology Journal Database, and Wanfang Database until the end of 2020 for English and Chinese published literature. Randomized controlled trials (RCTs) to evaluate the effectiveness and safety of traditional Chinese herbal medicine for the treatment of MI associated with SDF will be included. Study selection and data extraction were performed independently by 2 reviewers, and the quality evaluation and risk assessment were assessed by the Cochrane collaboration's tool, and use the RevMan 5.3 software for meta-analysis. CONCLUSION: This study will evaluate the efficacy and safety of traditional Chinese herbal medicine for the treatment of MI due to SDF, which may provide some help for the clinician's decision.
