Inclusion criteria: ① randomized controlled study; ② experimental or clinical researches including those in parallel control group; ③ studies by using ginkgo leaf extract in treatment group. Exclusion criteria: repetitive investigations.DATA EXTRACTION: The 221 random and nonrandom articles about therapeutical effect of ginkgo leaf extract on senile disease were collected,and 25 animal experiments or clinical investigations were also included.However, among 196 papers, 175 were excluded because of nonrandom or repetitive trials, and 21 because of review papers.DATA SYNTHESIS: There were 1 099 patients and 355 animals in 25 experiments. The research results showed that ginkgo leaf extract could regulate level of lipid and improve resistance of insulin on the aspect of treating diabetes mellitus (DM); effectively improve hypercoagulable state and hemorheological property on the aspect of treating hypertension; increase contents of levarterenol and 5-serotonin, protect cerebral ischemiareperfusion injury through up-regulating expression of Bcl-2 protein and down-regulating expression of Bax protein, and improve hemorheological indexes of patients with cerebral infarction and diabetes mellitus on the aspect of treating cardio-cerebral vascular disease; protect activity of adenosine triphosphate (ATP) enzyme in cerebral tissue, inhibit injured effect of oxygen-derived free radicals on mitochondrial RNA, delay cerebral senility, and improve learning and memory ability of senile rats on the aspect of treating anti-senility and senile dementia. Ginkgo leaf extract has been widely used in treating hypertension, diabetes mellitus, cerebral senility, senile dementia, cardio-cerebral vascular disease, etc., but there are no reports on side events.CONCLUSION: Ginkgo leaf extract is a valuable drug and also has a wonderful prospect in treating senile disease.

Objective We have recently shown that 5-azacytidine and butyrate can trigger apoptosis in human liver cancer cells. The purpose of our present study was to determine the effects of 5-azacytidine and butyrate on the invasion of liver cancer cells and the changes of the protein expression in the liver cancer cells during the treatment with these agents. Method Human liver cancer cell lines HepG2 and Hep3B were treated with either 5-azacytidine or butyrate; in vitro cell invasion, adhesion and proliferation, as well as the expression of the cell cycle inhibitory proteins p21waf1, p27kip1 and p53 were observed.Results Our results demonstrated that the combination of 5-azacytidine and butyrate effectively blocked in vitro invasion of these two liver cancer cell lines. Both agents inhibited the adhesion and proliferation of the liver cancer cells. The expression of p21waf1 and p27kip1 protein in the liver cancer cells was increased by the treatment with either agent. These two proteins may contribute to the inhibition of the liver cancer cells invasion.Conclusion Our finding suggests that the agents that specifically target the cell cycle inhibitor genes may clinically useful in the adjuvant treatment of liver cancers.

Objective To investigate the interaction between endometrium and embryo under the co-culture condition during the planting window stage. Methods Twenty patients who cancelled transplant for OHSS in the Reproductive Center of the second affiliated hospital of Zhengzhou university were enrolled.The discarded embryos were used to build the embryos co-culture system (Group A), with a single membrane (group B) and a single embryo(group C)as the control group. Levels of LIF and IGF expression and embryo growth were checked on 3, 4,5,6,7 day post-oocyte retrieval. Results Expressions of LIF mRNA and IGF mRNA in Group A were significantly higher than those in Group B. Embryo growth in the Group A was better than that in Group C. Conclusion Co-culture of endometrium and embryo supports the development of embryo and improves the receptivity of endometrium.

The binding of the nuclear factor erythroid 2 related factor 2(Nrf2)to the antioxidant response elements(ARE)can start the expression of batches of antioxidant proteins,anti-inflammatory factors and detoxification enzymes. Nrf2/ARE signalling plays a pivotal role in anti-inflammation and in preventing xenobiotics induced lesions. Besides involvenment in physiological processes,such as regulating nutrient metabolism,Nrf2/ARE signalling also functions in the pathogenesis of various dieases. This review outlines the strcuture,functions,and regulation of Nrf2/ARE signal pathways.
