ABSTRACT
BACKGROUND: The current evidence on the association between obesity-associated markers and semen quality, serum reproductive hormones and lipids remains inconsistent. In this study, we tested the hypothesis that, in infertile Chinese men, body mass index (BMI) negatively correlates with sperm concentration, serum total testosterone (TT), and high-density lipoprotein cholesterol (HDL-C). The relationship between other obesity-associated markers and semen quality parameters, serum reproductive hormones, lipids and leptin were also investigated. METHODS: 181 Chinese infertile men were recruited from September 2018 to September 2019. Their obesity-associated markers, semen parameters, and serum reproductive hormones, lipids and leptin were detected. Statistical analysis was performed to assess the relationship between obesity-associated markers and semen quality, serum reproductive hormones, lipids and leptin. RESULT(S): Statistically negative correlation was found between other obesity-associated markers (e.g. waist-to-hip ratio and waist-to-height ratio) and semen parameters (e.g. sperm concentration, ratio of progressive motility and ratio of non-progressive motility), while no significant correlation was found between BMI and semen quality, serum reproductive hormones, lipids and leptin. Ratio of morphologically normal sperm was negatively correlated with serum lipids including total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), leptin and seminal superoxide dismutase. Ratio of progressive sperm, sperm concentration and ratio of morphologically normal sperm exhibited significantly lower values in overweight group than normal group. Estradiol (E2) and E2/TT were significantly higher in obese group than normal group, while TT level was significantly lower in obese group than normal group. Univariate and multivariate analysis indicated that TC was significantly associated with BMI. Serum leptin concentration was positively correlated with seminal leptin concentration in overweight and obese groups. CONCLUSION(S): No significant correlation was found between BMI and sperm concentration, serum TT and HDL-C, while other obesity-associated markers were found to negatively correlate with sperm concentration, ratio of progressive motility and ratio of non-progressive motility. Statistically significant correlations between serum reproductive hormones, lipids and leptin also existed in Chinese infertile men.

OBJECTIVE: To investigate the clinical effects of the combined therapy of Compound Xuanju Capsules (CXJC) and traditional Chinese medicinal formula on infertility in male smokers. METHODS: A total of 176 male infertility patients were divided into a smoking and a non-smoking group and the former further divided into mild, moderate and heavy smokers according to the daily consumption of cigarettes and the length of smoking history. The patients were treated with CXJC combined with traditional Chinese medicinal formula for 3 four-week courses and the therapeutic results were evaluated by comparing the indicators of the traditional Chinese medicine (TCM) syndrome, routine semen parameters, sperm morphology, and sperm DNA fragmentation index (DFI) among different groups before and after treatment. RESULTS: The baseline TCM syndrome scores were remarkably higher in the heavy smokers than in the non-smoking group (P < 0.05) but showed no statistically significant differences between the mild and moderate smokers (P > 0.05). The baseline percentage of sperm head defects and DFI were also markedly higher in the heavy and moderate smokers than in the non-smoking group (P < 0.05). Compared with the baseline, significant improvement was achieved after treatment in the TCM syndrome, routine semen parameters, sperm morphology and sperm DFI, especially in the heavy smokers in the percentages of grade a+b sperm (ï¼»17.12 ± 2.54ï¼½ vs ï¼»30.15 ± 3.10ï¼½%, P < 0.05), morphologically normal sperm (ï¼»15.54 ± 1.98ï¼½ vs ï¼»26.82 ± 3.52ï¼½%, P < 0.05), and head-defective sperm (ï¼»27.02 ± 2.14ï¼½ vs ï¼»22.07 ± 1.52ï¼½%, P < 0.05). CONCLUSIONS: Sperm quality is significantly decreased while the risk of infertility remarkably increased in moderate and heavy smokers. The combined therapy of CXJC and traditional Chinese medicinal formula can effectively improve semen quality, sperm morphology and sperm DFI in male smokers with infertility, though more evidence is to be collected from further studies.

Importance: Acupuncture is used to induce ovulation in some women with polycystic ovary syndrome, without supporting clinical evidence. Objective: To assess whether active acupuncture, either alone or combined with clomiphene, increases the likelihood of live births among women with polycystic ovary syndrome. Design, Setting, and Participants: A double-blind (clomiphene vs placebo), single-blind (active vs control acupuncture) factorial trial was conducted at 21 sites (27 hospitals) in mainland China between July 6, 2012, and November 18, 2014, with 10 months of pregnancy follow-up until October 7, 2015. Chinese women with polycystic ovary syndrome were randomized in a 1:1:1:1 ratio to 4 groups. Interventions: Active or control acupuncture administered twice a week for 30 minutes per treatment and clomiphene or placebo administered for 5 days per cycle, for up to 4 cycles. The active acupuncture group received deep needle insertion with combined manual and low-frequency electrical stimulation; the control acupuncture group received superficial needle insertion, no manual stimulation, and mock electricity. Main Outcomes and Measures: The primary outcome was live birth. Secondary outcomes included adverse events. Results: Among the 1000 randomized women (mean [SD] age, 27.9 [3.3] years; mean [SD] body mass index, 24.2 [4.3]), 250 were randomized to each group; a total of 926 women (92.6%) completed the trial. Live births occurred in 69 of 235 women (29.4%) in the active acupuncture plus clomiphene group, 66 of 236 (28.0%) in the control acupuncture plus clomiphene group, 31 of 223 (13.9%) in the active acupuncture plus placebo group, and 39 of 232 (16.8%) in the control acupuncture plus placebo group. There was no significant interaction between active acupuncture and clomiphene (P = .39), so main effects were evaluated. The live birth rate was significantly higher in the women treated with clomiphene than with placebo (135 of 471 [28.7%] vs 70 of 455 [15.4%], respectively; difference, 13.3%; 95% CI, 8.0% to 18.5%) and not significantly different between women treated with active vs control acupuncture (100 of 458 [21.8%] vs 105 of 468 [22.4%], respectively; difference, -0.6%; 95% CI, -5.9% to 4.7%). Diarrhea and bruising were more common in patients receiving active acupuncture than control acupuncture (diarrhea: 25 of 500 [5.0%] vs 8 of 500 [1.6%], respectively; difference, 3.4%; 95% CI, 1.2% to 5.6%; bruising: 37 of 500 [7.4%] vs 9 of 500 [1.8%], respectively; difference, 5.6%; 95% CI, 3.0% to 8.2%). Conclusions and Relevance: Among Chinese women with polycystic ovary syndrome, the use of acupuncture with or without clomiphene, compared with control acupuncture and placebo, did not increase live births. This finding does not support acupuncture as an infertility treatment in such women. Trial Registration: clinicaltrials.gov Identifier: NCT01573858.

OBJECTIVE: To study the effect and potential mechanism of Modified Cangfu Daotan Decoction (MCDD) on endometrial receptivity in infertility patients with polycystic ovarian syndrome (PCOS). METHODS: Totally 298 women having normal ovulation who underwent artificial insemination were recruited as the control group, and they received no drug therapy. Another 355 infertility patients with PCOS who received ovarian stimulation therapy were recruited as the treatment group. Then they were further assigned to the treatment group I (195 cases) and the treatment group II (160 cases) according to random digit table. Patients in the treatment group I received clomiphene (CC) + human menopause gonadotropin (HMG) +human chorionic gonadotropin (HCG), while those in the treatment group II received CC + HMG + HCG and additionally took modified MCDD. The therapeutic course for all was three menstrual cycles. The pregnancy ratio, the endometrial thickness, and spiral artery pulsatility index (PI), resistance index (RI), and homeostasis model assessment-insulin resistance (HOMA-IR) were measured. Furthermore, the uncoupling protein 2 (UCP2) level was tested by Western blot. RESULTS: Compared with the control group, the endometrial thickness decreased and PI and RI increased in the treatment group I (all P < 0.05). Compared with the treatment group I , the endometrial thickness increased and PI and RI decreased in the treatment group II (all P < 0.05). Compared with before treatment, HOMA-IR levels were significantly decreased in the treatment group II after treatment (P < 0.05). Compared with the control group before treatment, the HOMA-IR level increased in the treatment group I and the treatment group II before treatment (P < 0.05). Compared with the control group after treatment, the HOMA-IR level increased in the treatment group I (P < 0.05). But there was no statistical difference in the post-treatment HOMA-IR level between the control group and the treatment group II (P < 0.05). Compared with the control group, the post-treatment UCP2 level was increased in the treatment group II (P < 0.05). After one year follow-up, the pregnancy rate was 16.1% (48/298) in the control group, 23.1% (37/160) in the treatment group I, and 33.8% (66/195) in the treatment group II. Compared with the control group, the pregnancy rate was significantly increased in the treatment group II (P < 0.05). CONCLUSION: MCDD was found to be capable of increasing the pregnancy rate of infertility patients with PCOS, which might be associated with improving endometrial blood flow and insulin resistance, increasing the UCP2 expression, and finally improving the endometrial receptivity.

ABSTRACT
Polycystic ovary syndrome (PCOS) is an endocrine disease associated with reproduction. The Cuscuta-Salvia formula has been widely used to treat for PCOS in clinic. However, its chemical and pharmacological properties remain unclear. We identified the active components and related targets of Cuscuta-Salvia using UHPLC-ESI-Q-TOF-MS and TCMSP database. Disease targets were obtained from the DisGeNET and GeneCards databases. Subsequently, common targets between Cuscuta-Salvia and PCOS were identified using a Venn diagram. PPI network was established. Core genes were selected using a Cytoscape software plugin. GO and KEGG enrichment analyses were performed for common targets using the "pathview" package in R. Several core targets were verified using molecular and Immunological methods. By combining UHPLC-ESI-Q-TOF-MS with a network pharmacology study, 14 active components and a total of 80 common targets were obtained. Ten core genes were regulated by Cuscuta-Salvia in PCOS, including IL6, AKT1, VEGFA, TP53, TNF, MAPK1, JUN, EGF, CASP3, and EGFR. GO results showed that cellular response to drugs, response to oxygen levels, response lipopolysaccharides, and response to molecule of bacterial origin in BP category; membrane, transcription regulator complex, nuclear chromatin, postsynaptic membrane, and vesicle lumen in CC category; DNA-binding transcription factor binding, RNA polymerase II-specific DNA-binding transcription factor binding, DNA-binding transcription activator activity, RNA polymerase II-specific, DNA-binding transcription activator activity, and cytokine receptor binding in MF terms. The KEGG enrichment pathway was mainly involved in the PI3K - Akt, MAPK, TNF, IL-17 signalling pathways, and in cellular senescence. Furthermore, the results of the experimental study showed that Cuscuta-Salvia ameliorated the pathological changes in the ovaries, liver and adipose tissue. And it improved the expressions of the genes or proteins. Our results demonstrate that Cuscuta-Salvia may provide a novel pharmacological basis in an experimental model of PCOS by regulating gene expression. This study provides a basis for future research and clinical applications.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetes mellitus-induced erectile dysfunction (DMED) is one of the most common complications of diabetes mellitus. Leech and centipede granules (LCG) have traditionally been used as blood-activating agents in various ethnomedicinal systems of East Asia, especially in China. It is often used to regulate bodily functions and considered as adjuvant therapy for promoting blood circulation, alleviating blood coagulation, activating meridians, and relieving stasis. AIM OF THE STUDY: This study aimed to identify potential genes and mechanisms of LCG on DMED from the network pharmacological perspective. MATERIALS AND METHODS: The active components of LCG were identified by UHPLC-Q-TOF-MS, TCMID, and the BATMAN-TCM databases, and the disease targets of DMED were obtained from the DisGeNET, CooLGeN, GeneCards databases. After identifying DMED targets of LCG, a protein-protein interaction (PPI) network was constructed. Hub genes and significant modules were identified via the MCODE plug-in of Cytoscape software. Then, significant signaling pathways of the modules were identified using the Metascape database. The probable interaction mode of compounds-hub genes is examined using Molecular Operating Environment (MOE) docking software. Besides, we investigated the effects and mechanisms of LCG on improving erectile function in the streptozotocin (STZ)-induced diabetic rats model. RESULTS: Combined UHPLC-Q-TOF-MS analysis with network pharmacology study, 18 active compounds were selected for target prediction. There are 97 common target genes between LCG and DMED. Enrichment of the KEGG pathway mainly involves in the calcium signaling pathway, NF-kappa B signaling pathway, cGMP-PKG signaling pathway, HIF-1 signaling pathway, PI3K-Akt signaling pathway, and mTOR signaling pathway. Nine hub genes were regulated by LCG in DMED, including CXCL8, NOS3, CRH, TH, BDNF, DRD4, ACE, CNR1, and HTR1A. The results of molecular docking analysis showed that the tyrosin, ursolic acid, and L-Histidine has a relatively stable interaction with corresponding hub genes via generating hydrogen bonds, H-π, and π-π interactions. Significantly, the results in docking predicted a higher affinity of vardenafil to the hub genes compared to the tyrosin, ursolic acid, and L-Histidine. Furthermore, LCG increased the testosterone, erection frequency, the ratio of ICP and MAP, SOD, cGMP, cAMP as well as decreased the MDA, and AGEs expression levels. And, LCG ameliorated the histological change of penile tissues in DMED rats. Hence, LCG attenuates oxidative stress, increases NO production; For the mechanism exploration, LCG could significantly upregulate the mRNA and protein expression of CNR1, NOS3, CRH, TH, BDNF, and DRD4, whereas CXCL8, ACE, and HTR1A levels were significantly higher than those in the DMED group. Moreover, LCG activates the NO/cGMP/PKG pathway, PI3K/Akt/nNOS pathway, cAMP/PKA pathway, and inhibits the HIF-1α/mTOR pathway to improve erectile function. CONCLUSIONS: Our results suggest that LCG maybe offer a new therapeutic basis for the treatment of DMED via altering the gene expression of involved metabolic pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Wuzi Yanzong pill (WZYZP) is a classical traditional Chinese medicine (TCM) formula originated from the Tang dynasty. WZYZP has a long history of use for reinforcing kidney and alleviating male infertility in China. AIM OF THE STUDY: The effect of WZYZP on male infertility and the mechanism underlying this effect was not clarified clearly. Therefore, this study aimed to investigate the protective effect of WZYZP in experimental spermatogenesis disorder via in vivo and in vitro studies, to promote the use of this formula for the treatment of spermatogenesis disorder. MATERIAL AND METHODS: Male SD rats were exposed to tripterygium glycosides to induce experimental spermatogenesis disorder, and WZYZP was subsequently administrated at different dosages for treatment. Sperm counts, sperm motility, and serum hormone levels were detected. HE staining and TUNEL staining were performed to evaluate the pathological lesions and apoptosis of testes, respectively. Next, germ cells were isolated from spermatogenesis disorder-model rats and treated with WZYZP- containing serum at different concentrations. CCK-8 assay and flow cytometry assay were performed to detect cell proliferation and apoptosis. Immunofluorescence assay, qRT-PCR and Western blotting analyses were performed to detect the expression of Beclin 1, LC3 and TGF-ß-PI3k/AKT-mTOR pathway - related factors, including TGF-ß, PI3K, AKT, mTOR, 4 EBP-1 and p70S6K. RESULTS: In vivo experiments showed that WZYZP protected against spermatogenesis disorder in model rats by improving sperm count and motility, as well as restoring serum hormone levels. HE and TUNEL staining demonstrated that the pathological injuries and cell apoptosis in testes of the model rats were alleviated by WZYZP treatment. Moreover, in vitro experiments of germ cells isolated from spermatogenesis disorder-model rats showed that WZYZP treatment increased the cell proliferation, inhibited cell apoptosis and autophagy. qRT-PCR and Western blotting assay results showed that this protective effect was associated with the regulation of the TGF-ß/PI3K/AKT/mTOR signaling pathway. The expression levels of p-PI3K/PI3K, p-AKT/AKT, p-mTOR/mTOR, 4 EBP-1 and p70S6K were increased, while TGF-ß was inhibited in the WZYZP treated groups. CONCLUSION: The results showed that WZYZP could protect against experimental spermatogenesis disorder by increasing the germ cell proliferation and inhibiting their apoptosis. Our support the clinical use of this formula for the management of spermatogenesis disorder.

The crisis of male infertility is an issue of human reproductive health worldwide. The Wuzi Yanzong pill (WZYZP) is a traditional Chinese medicine prescription that shows efficacy in kidney reinforcement and essence benefit to ameliorate male reproductive dysfunctions. However, the pharmacological mechanisms of the WZYZP on male infertility have not been investigated and clarified clearly. This study was designed to investigate the effects of the WZYZP on spermatogenesis disorder and explore its underlying pharmacological mechanisms. First, based on a network pharmacology study, 39 bioactive compounds and 40 targets of the WZYZP associated with spermatogenesis disorder were obtained, forming a tight compound-target network. Molecular docking tests showed tight docking of these compounds with predicted targeted proteins. The protein-protein interaction (PPI) network identified TP53, TNF, AKT1, Bcl-XL, Bcl-2, and IκBA as hub targets. The Kyoto Encyclopedia of Genes and Genomes pathway network and pathway-target-compound network revealed that the apoptosis pathway was enriched by multiple signaling pathways and multiple targets, including the hub targets. Subsequently, the chemical characterization of WZYZP was analyzed using liquid chromatography to quadrupole/time-of-flight mass spectrometry, and 40 compounds in positive ion mode and 41 compounds in negative ion mode in the WZYZP were identified. Furthermore, based on the prediction of a network pharmacology study, a rat model of spermatogenesis disorder was established to evaluate the curative role and underlying mechanisms of the WZYZP. The results showed that WZYZP treatment improved rat sperm quality and attenuated serum hormone levels, reversed histopathological damage of the testis, reduced cell apoptosis in testis tissues, and ameliorated the expression of the predicted hub targets (TP53, TNF-α, AKT1, NFκB, and IκBA) and the apoptosis related proteins (Bcl-XL, Bcl-2, Bax, Caspase 3, and Caspase 9). These results indicated that the WZYZP has a protective effect on spermatogenesis disorder, suggesting that it could be an alternative choice for male infertility therapy.
ABSTRACT
Erectile dysfunction (ED) is one of the significant complications of diabetes mellitus (DM), and CASR plays an important role in cellular antiapoptosis and NO production in the vascular endothelium by activating PKC. The present study was aimed to investigate the efficacy of Leech and Centipede Granules (LCG) through the CaSR/PLC/PKC signaling. Fifty male Sprague-Dawley rats were treated with streptozotocin to induce the DM model. After 10 weeks, an apomorphine test was used to confirm DMED. Rats with DMED were administrated with LCG and U73122 for 4 weeks. Fasting blood glucose, body weight, insulin and glucagon levels were measured. Erectile function in rats was assessed by apomorphine. Serums were measured using enzyme-linked immunosorbent assay and flow cytometry, and penile tissues were harvested for histologic and the expression of related targets analyses. After treatment, fasting blood glucose, body weight, insulin, glucagon levels, and erectile function were significantly ameliorated in the LCG groups. The LOX-1, NOX, and EMPs concentrations were significantly decreased with LCG treatment. LCG also continuously increased NO and decreased ET-1 content in penile tissues. LCG and U73122 administration also improved penile fibrosis by significantly decreasing VCAM-1, ICAM-1, and CD62P. The data also showed that LCG reduced the apoptosis level in the penis. Furthermore, the inhibited activation of the CaSR/PLC/PKC pathway was observed in DMED rats with LCG treatment. Collectively, LCG significantly ameliorated erectile function of DMED rats via increased NO generation, inhibiting endothelial cells apoptosis and penile fibrosis, which might benefit from the suppression of CaSR/PLC/PKC pathway in DMED rats.

OBJECTIVE: To explore the prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with polycystic ovary syndrome (PCOS). METHODS: A case-control study employing 60 nonpregnant patients with PCOS and 60 non-pregnant patients without PCOS as control was conducted to compare the prevalence of NAFLD. RESULTS: The aminotransferase (ALT), fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) levels were (29 +/- 15) U/L, (19 +/- 12) mU/L and 0.47 +/- 0.29 in PCOS group, which were significantly higher (P < 0.05) than corresponding parameters in control group [(15 +/- 13) U/L, (11 +/- 8) mU/L and 0.31 +/- 0.21)]. The occurrence of insulin resistance and NAFLD was63% (38/60) and 42% (25/60), higher than those in control group [35% (21/60) and 20% (12/60), P < 0.05]. The increment of ALT was 40% (24/60) in PCOS group, higher than that of 3% (2/60) in control group (P < 0.01). Compared with patients without NAFLD, patients with NAFLD had significantly increased body mass index (P < 0.01), waist-hip ratio, ALT, C-reaction protein, fasting insulin, insulin and HOMA-IR levels 2 hours after oral glucose tolerance test (P < 0. 05). CONCLUSION: The increased prevalence of NAFLD in PCOS patients suggests an association between these two conditions and the necessity of hepatic screening among PCOS patients for potential NAFLD.

OBJECTIVE: To explore the ultrastructure and function of mitochondria in idiopathic asthenospermia and the role thereof in the sperm activity. METHODS: Samples of sperm were collected from 151 idiopathic asthenospermia patients, 25% of whose sperms were classified as lower than grade A, were subdivided into 3 groups: Group A with the proportion of grade A sperms between 15% and 25%, Group B, with the proportion of grade A sperm between 15% and 5%, and Group C with the proportion of grade A sperm < 5%. Transmission electron microscopy was used to observe the ultrastructure of the mitochondria in the sperms. Samples of sperm were collected from 53 normal patients as control group. The levels of succinate dehydrogenase (SDH) and mitochondrial membrane potential (MMP) were detected. RESULTS: The expression rates of SDH and MMP were decreased according to the sequence of the control group, group A, Group B, and Group C with significant between any two groups (all P < 0.01). Various mitochondrial pathological changes (MPCs) emerged in Groups A, B and C, however with different frequencies of occurrence for specific MPC in specific group (chi2 = 60.85, P < 0.01). The amount of abnormal mitochondria increased significantly according to the sequence of the control group, Groups A, B and C (chi2 = 479.72, b = 0.86, P < 0.01). The severity degree of MPC increased along with the decrease of sperm viability (chi2 = 435.89, b = 0.80, P < 0.01). CONCLUSION: Various MPCs exist in idiopathic asthenospermia. There is a close association between the sperm viability and mitochondrial ultrastructure and mitochondrial function.

OBJECTIVE: To study the effect of Qingre Yulin Decoction (QYD) on male infertility caused by accessory gland infection (AGI) with randomized controlled trial (RCT). METHODS: Sixty infertility outpatients were equally divided into two groups randomly, the QYD group treated with modified QYD and the control group with antibiotic plus vitamin E, both for 3 months with another 6 months' follow-up. Pregnant rates, routine test of sperm and expressed prostatic secretion (EPS) were determined. RESULTS: The healed rate was 26.7% (8 cases), the markedly effective rate was 43.3% (13 cases), the effective rate was 16.7% (5 cases), and the total effective rate was 86.7% in the QYD group, while in the control group it was 6.7% (2), 30.0% (9), 40.0% (12) and 76.7% respectively, showing higher healed rate and total effective rate in the former than those in the latter. Sperm quality of infertility patients with AGI decreased obviously, manifesting short ened average liquefaction time, reduced concentration, survival rate and vitality of sperm. These abnormal changes were improved after treatment in both groups, and the efficacy was better in the QYD group than that in the control group. CONCLUSION: Infertility patients with AGI were manifested as oligospermatism and asthenospermia, which may not be the definite outcome of AGI. QYD is able to improve sperm quality, especially sperm vitality in infertility patients with AGI and therefore increase pregnant rate of their wives.

OBJECTIVE: To study the intervention of Morindae officinalis extract in human sperm membrane, and to study the treatment of male infertility and asthenoospermia by M. officinalis. METHOD: To select sperm with normal physiological function using the Percoll gradient centrifugation for the normal sperm model. Then separating the sperm suspension into the normal, model, and control group (Vitamin C group), and the large, medium and small dose of M. officinalis. The ROS was made from hypoxanthine-xanzine xanzine (HX-XO), and ROS, different concentrations (0.125, 0.25, 0.5 mg x mL(-1) of the extract were hatched with sperm in the oxygen environment, the sperm membrane Lipid peroxide injury were analyzed, and the function of sperm membrane were analyzed by sperm Hypoosmoticswelling (HOS) and compared with the controlled group. RESULT: In the same conditions, all the small, medium and large extracts of M. officinalis (0.125, 0.25, 0.5 g x mL(-1)) improved SOD vitality of sperm suspension, reduced the content of MDA, intervened in the injury of sperm membrane by ROS to some extent and protected some function of sperm membrane. The 0.125 mg x mL(-1) extract had no obvious difference (P > 0.05) with Vitamin C in it, but the (0.25, 0.5 mg x mL(-1)) concentration of the extract is significantly better than control Vitamin-C (P < 0.01, P < 0.001). Furthermore, there was a dependence on the dosage, the large dose (0.5 mg x mL(-1)) of M. officinalis especially protected the function of sperm membrane. CONCLUSION: The extract from M. officinalis can significantly intervene in lipin peroxidation in sperm membrane by guarding against oxidation, and protect the structure and function of sperm membrane, that is one of the mechanisms for treating male's infertility and asthenoospermia with M. officinalis.

OBJECTIVE: To study the oxidation damage of active oxygen (ROS) to human sperm acrosome and ultrastructure, and study the function mechanism about Cuscuta japonica treating male's infertility and asthenoospermia. METHOD: By using the Percoll gradient centrifugation, the sperm with normal physiological function were selected for the normal sperm model, and the sperm suspension were divided into the normal group, the model group, the positive control group (Vitamin C group), and the lugh, the median and the low dose gvoups of C. japonica. The ROS made from hypoxanthine-xanzine xanzine(HX-XO) and different content (0.125, 0.25, 0.5 g x mL(-1)) of extract were incubated with sperm in the oxygen environment. The acrosomic integrity rate were calculated and the sperm acrosome and ultrastructure were observed. RESULT: The content (0.125, 0.5 g x mL(-1)) of extract had no obvious difference as compared with Vitamin C (0.25 mg x mL(-1)) in protecting the acrosome and ultrastructure, but the content (0.25 mg x mL(-1)) of extract was significantly better than Vit C (P < 0.001). CONCLUSION: The suitable content of extract from C. japonica can significantly protect the sperm membrane, the acosomic structure and the mitochondrion function from the damage caused by ROS.

AIM: To explore the pattern of expression of circulating miRNAs in patients with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: Microarray and qRT-PCR were used to investigate circulating miRNAs in PCOS during clinical diagnosis. The targets of dys-regulated miRNAs were predicted using bioinformatics, followed by function and pathway analysis using the databases of Gene Ontology and the KEGG pathway. RESULTS: BMI, triglyceride, HOMA-IR, Testosterone and CRP levels were significantly higher, while estradiol was significantly lower in PCOS than in control groups. After SAM analysis, 5 circulating miRNAs were significantly up-regulated (let-7i-3pm, miR-5706, miR-4463, miR-3665, miR-638) and 4 (miR-124-3p, miR-128, miR-29a-3p, let-7c) were down-regulated in PCOS patients. Hierarchical clustering showed a general distinction between PCOS and control samples in a heat map. After joint prediction by different statistical methods, 34 and 41 genes targeted were up-and down-regulated miRNAs, in PCOS and controls, respectively. Further, GO and KEGG analyses revealed the involvement of the immune system, ATP binding, MAPK signaling, apoptosis, angiogenesis, response to reactive oxygen species and p53 signaling pathways in PCOS. CONCLUSIONS: We report a novel non-invasive miRNA profile which distinguishes PCOS patients from healthy controls. The miRNA-target database may provide a novel understanding of PCOS and potential therapeutic targets.
