Schisandra is the mature fruit of Schisandra chinensis(known as "north Schisandra") or S. shenanthera(known as "south Schisandra"). S. chinensis contains a variety of lignans, volatile oils, polysaccharides, organic acids and other chemical constituents; among them, lignans are recognized as the characteristic active components. Clinical studies have found that Schisandra and Schisandra-related products have a better effect in the prevention and treatment of viral hepatitis, drug-induced liver injury, liver cirrhosis, liver failure and other liver diseases. Modern pharmacological studies have demonstrated that Schisandra has a variety of pharmacological activities, such as anti-inflammation, antioxidation, anticancer, regulation of nuclear receptor, antivirus, regulation of cytochrome P450 enzyme, inhibition of liver cell apoptosis and promotion of liver regeneration. This paper reviews the studies about the applications and mechanism of Schisandra in the prevention and treatment of liver diseases, in the expectation of providing guidance for the development of hepatoprotective drugs from Schisandra and the clinical applications of Schisandra-related products.

<p><b>OBJECTIVE</b>To observe the effect of electro-acupuncture (EA) treatment on the oocyte quality in polycystic ovarian syndrome (PCOS) patients undergoing in vitro fertilization-embryo transfer (IVF-ET).</p><p><b>METHODS</b>Totally 217 PCOS patients undergoing IVF-ET were assigned to two groups by random digit table, the EA group (119 cases) and the control group (98 cases). All patients received long program ovarian hyperstimulation with gonadotropin-releasing hormone agonist. Patients in the EA group received EA treatment in the process of controlled ovarian hyperstimulation till the oocyte retrieval day. The position relation of the spindle to the polocyte, the number of retrieved oocytes, the fertilization rate,the cleavage rate,the high quality embryo rate, the ovarian hyperstimulation syndrome (OHSS) incidence rate, the clinical pregnancy rate, the early abortion rate, the gonadotropins (Gn) dose and time, levels of estradiol (E2), progesterone (P), and luteinizing hormone (LH) on the day of human chorionic gonadotropin (HCG) were observed between the two groups.</p><p><b>RESULTS</b>The ratio of oocytes in which the meiotic spindle deviation angle was < 60 degrees to the all oocytes was obviously higher in the EA group than in the control group (P < 0.05). The oocytes in which the meiotic spindle deviation angle was < 60 degrees was positively related to level of E2 on the HCG day and the high quality embryo rate (r = 0.19,P < 0.01). Compared with the control group, the high quality embryo rate increased significantly (P < 0.05), the dose and days of Gn decreased significantly (P < 0.05) in the EA group. The clinical pregnancy rate was improved by 8.36%.</p><p><b>CONCLUSIONS</b>The spindle was positively correlated with the oocyte quality. EA could improve the quality of oocytes and the clinical pregnancy rate in PCOS patients undergoing IVF-ET.</p>

<p><b>OBJECTIVE</b>To explore the impacts of electroacupuncture on embryo implanted potential and its molecular mechanism in the patients with infertility of different symptom complex.</p><p><b>METHODS</b>Among the patients with infertility treated with electroacupuncture and in vitro fertilization and embryo transplantation (IVF-ET), 82 cases of kidney deficiency (group A), 74 cases of liver qi stagnation (group B) and 54 cases of phlegm dampness (group C) were selected. All of the patients in three groups received long-program ovarian hyper-stimulation. Additionally, electroacupuncturecan was applied before controlled ovarian hyper-stimulation (COH) and in the process of ovarian hyper-stimulation. The levels of human leukocyte antigen-G (HLA-G) in the serum were determined on the 2nd day of the menstruation (M2), on the day of human Chorionic Gonadotropin (hCG) injection and on the day of embryo transplantation in the culture solution in three groups separately. The fertilization rate, implantation rate and clinical pregnancy rate were observed for the patients in three groups.</p><p><b>RESULTS</b>The levels of HLA-G in the serum on hCG injection day and in the culture solution on embryo transplantation day in group A and B were significantly higher than those in group C (all P < 0.05). But, there was no significant difference in serum HLA-G levels on M2 day among three groups. The high-quality embryo rate in either group A (73.6%, 352/478) or group B (70.6%, 379/537) was higher significantly than that in group C (54.2%, 208/384) separately, presenting statistical significant difference (all P < 0.01). But there were no significant differences in clinical pregnancy rate, fertilization rate and cleavage rate among three groups.</p><p><b>CONCLUSION</b>Electroacupuncture can increase the contents of HLA-G in the body and the level of HLA-G secreted in embryos for the patients in the process of IVF-ET. Eventually, the pregnancy outcome and the pregnancy rate are improved. The clinical effects of electroacupuncture for the patients of kidney deficiency and liver qi stagnation are better than those for the patients of phlegm dampness.</p>
