ABSTRACT
In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.
ABSTRACT
Ginsenoside Rb3 (GRb3) is one of the main components in plasma of Panax quinquefolius Saponin of stem and leaf (PQS), which can be into human plasma. Previous studies have found PQS has estrogen-like vascular protective effects. In the present study, we investigated the estrogen-like protective effect of GRb3 on oxidative stress and dysfunction of endothelial cells induced by oxidized low-density lipoprotein. The activities of SOD, NOS and the contents of MDA in the cell lysate were examined by enzyme method or spectrophotometry. The NO and ET-1 concentrations in the cell culture supernatant were measured by ELISA method. The iNOS and eNOS mRNA expression were measured by real time RT-PCR, while the phosphorylation levels of Akt was measured by Western blotting. The results showed that GRb3 could enhance the activity of SOD, reduce the content of MDA, increase the level of NOS, NO, ET-1 and iNOS mRNA expression while decrease the eNOS mRNA expression and the phosphorylation level of Akt. These effects were blocked by estrogen receptor antagonist ICI182780. GRb3 can play a role in protecting vascular endothelial cells by estrogen receptors, the protective mechanism is similar to 17-β estrodiol.
