    Abstract This study investigates the inhibitory effect of astaxanthin (AST) on testosterone-induced benign prostatic hyperplasia (BPH) in rats. Except for the sham operation, BPH model rats were randomly assigned to five groups: the BPH model control rats, AST-treated BPH model rats (20 mg/kg, 40 mg/kg, and 80 mg/kg), and epristeride (EPR)-treated BPH model rats. After treatment, as compared with the BPH model control rats, the prostate and ventral prostate weights of the AST-treated rats decreased, while there was a marked decline in the 80 mg/kg AST-treated rats. The same effect was also observed in the prostate index and ventral prostate index. The proliferation characteristics of epithelia observed in the BPH model control group were gradually alleviated in the AST-treated rats. As compared with the BPH model control rats, lower epithelial thicknesses of prostates and fewer secretory granules in epithelia were observed in the AST-treated rats. The superoxide dismutase (SOD) activity of prostates increased in all the AST-treated rats with a significant increase in the 40 mg/kg and 80 mg/kg AST-treated rats. The testosterone (T) and dihydrotestosterone (DHT) levels of prostates in the AST-treated groups were lower than those in the BPH model control group, and a significant decline was found in the T level of prostates in the 40 g/kg and 80 mg/kg AST-treated rats and the DHT level of prostates in the 40 mg/kg AST-treated rats. These results indicate that AST might have an inhibitory effect on T-induced BPH in rats, possibly due to SOD activity regulation and T and DHT levels.

    Abstract Prostaglandin synthase (PGS) can catalyze the production of various types of prostaglandins and regulate the expression levels of related substances. The regulation mechanisms of the PGS gene are closely related with the occurrence and development of prostate diseases. However, few studies are reported on the regulation mechanisms of PGS in prostatic diseases, such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa), or on the relationship between PGS gene regulation and prostate diseases. This review aims to analyze their correlation and provide some ideas for the prevention and control of BPH and PCa by intervention of the prostaglandin synthase regulatory pathway.

    Abstract Objective: To establish an in vitro screening model for steroid 5 alpha-reductase inhibitors using the microplate reader.
    Methods: Steroid 5 alpha-reductase was obtained from the liver of female rats, an in vitro screening model for steroid 5 alpha-reductase inhibitors established using the 96-well plate and microplate reader after determination of the enzymatic activity, and the reliability of the model verified with the known 5 alpha-reductase inhibitors epristeride and finasteride. Added to the 96-well plate were the final concentrations of testosterone (0-40 micromol/L), NADPH (22 micromol/L), epristeride (0-60 nmol/L) or finasteride (0-60 nmol/ L) and steroid 5 alpha-reductase (20 microl), the total volume of each well adjusted to 200 microl with Tris-Hcl buffer. The 96-well plate was placed in the microplate reader, mixed and incubated at 37 degrees C, followed by detection of the A340nm value at 0 and 10 min and analysis of the data.
    Results: The Km value of steroid 5 alpha-reductase was 3.794 micromol/L, with a Vmax of 0.271 micromol/(L. min). The Ki of epristeride was 148.2 nmol/L, with an IC50 of 31.5 nmol/L, and the enzymatic reaction kinetic curve suggested that epristeride was an uncompetitive enzyme inhibitor. The Ki of finasteride was 158. 8 nmol/L, with an IC50 of 13.6 nmol/L. The enzymatic reaction kinetic curve showed that both epristeride and finasteride were competitive enzyme inhibitors, similar to those reported in the published literature.
    Conclusion: A screening model was successfully established, which could rapidly and effectively screen steroid 5 alpha-reductase inhibitors in vitro.

    Abstract Background: The Qilin pill (QLP) is a traditional Chinese compound prescription comprising 15 herbs that has demonstrated significant therapeutic effects on premature ovarian insufficiency (POI) in recent years. However, a pharmacological evaluation of QLP on ovarian function remains to be conducted, and the key mechanism of QLP treatment on POI is unclear.
    Methods: Premature ovarian insufficiency rats were established by bilateral partial ovariectomy. The model rats were administrated with low (QLP-L), medium (QLP-M) and high (QLP-H) doses of QLP for 4 weeks to evaluate the ovarian function in terms of estrous cycle, hormone level, and follicle count. The mechanism of QLP in the treatment of POI was systematically explored by network pharmacology, and expression levels of the MAPK and PI3K-AKT signaling pathways were verified by Western blotting and molecular docking.
    Results: The rat model of resection-induced POI was successfully established, and QLP could significantly recover the estrous cycle, decrease serum FSH levels, and decelerate follicle depletion after 4 weeks of administration. The optimal dose of QLP in the experiment was preliminarily determined to be 0.9 g/kg. Based on the network pharmacology methods, we constructed the compound-target network and protein protein interaction (PPI) network of QLP for the treatment of POI. The experimental verification of the enrichment analysis showed that QLP inhibited the MAPK and PI3K-AKT signaling pathways, and the key compounds and key targets involved were verified by molecular docking.
    Conclusion: QLP exerted significant therapeutic effects on resection-induced POI rats, and this was achieved by the inhibition of the MAPK and PI3K-AKT signaling pathways. This study is the first to systematically investigate the effects and mechanism of QLP on POI rats, which will provide valuable guidance in clinic.

    Abstract This report introduces a novel method, rabbit whole embryo culture (WEC) combined with toxicokinetics (TK), for toxicity testing. Rodent WEC has been extensively used for in vitro screening of developmental toxicity. To improve the reliability of in vitro data, it is important to consider TK and species specificity. To test the utility and effectiveness of this method, we investigated the toxic effect of thalidomide on rabbit embryos and its behavior in test systems both in vitro and in vivo under the same experimental condition. The data showed that thalidomide induced embryo malformations such as embryonic brain hypoplasia, short limb buds, and declined embryonic growth both in vitro and in vivo. The toxic effect increased with the increasing exposure of the embryo to thalidomide. In addition, we observed similar toxic effects and exposure-effect relationships in vivo and in vitro. Therefore, we preliminarily conclude that this new method can effectively predict and explain thalidomide toxicity. Furthermore, we investigated the behavior of test compounds in the WEC system for the first time, and this method is expected to be an important technique for in vitro toxicity study after extensive verification.

    Abstract Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder, which is characterized by hyperandrogenism, insulin resistance and chronic anovulation, and has become a serious threat to the health of adolescents and women of childbearing age.At present,lowering androgen, improving insulin resistance and inducing ovulation are the main methods adopted by doctors to treat the disease, but the adverse reactions of the western medicine and the long-term treatment are hard to be accepted by the patients. PCOS treated by traditional Chinese medicine has achieved a certain effect in recent years.Traditional Chinese medicine is relatively safe and has more effect in many links and targets in improving the symptom of endocrine and metabolic disorder in patients with PCOS. This paper expounds the traditional Chinese medicine pathogenesis of PCOS through clinical and experimental aspects of the literature research:correcting endocrine hormone disorder,the effects of the expression of gene and regulatory factors,improving insulin resistance,correcting lipid metabolic disorder,improving the pregnancy outcome and improving ovarian morphology to summarize the treatment of traditional Chinese medicine in PCOS research results in recent years.

    Abstract Prostate is sensitive to endocrine hormone level, and the synergetic effect of estrogen and androgen is critical in prostate growth. The change of signal pathways caused by the imbalance of estrogen and androgen might function in the occurrence of prostate diseases. As a well-known endocrine disruptor compound, bisphenol A (BPA) can disturb the normal function of endocrine hormone and affect prostate development. This study aims to investigate effects of BPA on the dorsolateral prostate (DLP) and the related gene expression of the tissue in adult

    Abstract Bisphenol A (BPA) is a well-known endocrine disruptor compound (EDC) that aggravates testosterone-induced benign prostate hyperplasia by increasing the relative weight of the ventral and dorsolateral prostate in rats. This phenomenon is primarily attributed to the exogenous estrogen effect of BPA. However, the direct effect of BPA on prostate cells has not been characterized. The present study investigated the proliferative effect and possible mechanisms of action of BPA on the prostatic epithelium of rats. The ventral prostate epithelial cells were cultured
