Schisandrae Chinensis Fructus is dry,mature fruits of magnolia plant Schisandra chinensis. In recent years,domestic and foreign scholars have made a lot of studies on active constituents of S. chinensis and pharmacological activities. This article systematically organizes the active constituents and pharmacological activities of S. chinensis. It was found that fruit,seeds,roots,stems and leaves of S. chinensis and other medicinal parts mainly contained lignans,volatile oils,triterpenoids,polysaccharides and flavonoids. And lignans were the main characteristic active ingredients of S. chinensis,triterpenoids,polysaccharides and volatile oils were the secondary active ingredients,and the activity of flavonoids had rarely been reported. According to the pharmacological study of S. chinensis,S. chinensis lignans had certain effects on the central nervous system,cardiovascular system,liver,kidney and reproductive system,with anti-oxidation,anti-tumor,anti-bacterial and anti-HIV effects. Other chemical components also had good pharmacological activities,but were less studied than lignans. With dual functions in medicine and food, it was widely used as a health product and medicine. This article systematically summarized the active constituents and pharmacological activities of S. chinensis,and provided an important reference and basis for the further development of the health product and medicine of S. chinensis in the future.

Cathepsin, with various species and functions, derives from cell endolysosome. It has great impact on both sustaining eubolism and preventing diseases. Cathepsin has positive effect on human beings through its moderate expression to enhance the cells in their activation, multiplication, and metabolism. While its excessive expression might have a negative effect of inducing other diseases. Traditional Chinese herbs have been a crucial part of traditional Chinese medicine and they are various in species with less side effect, which has been paid close attention to. So far, researches about cathepsin become abundant among researchers home and abroad, while Chinese materia medica just takes up its gradual research not long before. This paper aims at briefly summarizing the latest academic researches on cathepsin home and abroad in terms of dependency structure, features of pathology and physiology as well as the intervention of traditional Chinese herbs to cathepsin in order to give a clear picture on its development.

Objective: To study the pharmacodynamic effect of “unification of medicines and excipients” and the mechanism of action about Shaoyao Gancao Intragastric Floating Tablets (SGIFT). Methods: Rabbits were randomly divided into control group and model group, Shenmei Yangwei Granule group (1.0 g/kg), Shaoyao Gancao Decoction extract group (1.0 g/kg), low-dose SGIFT group (1.0 g/kg), high-dose SGIFT group (1.5 g/kg), chitosan blank excipients group (1.0 g/kg). The acute gastric ulcer model was established in the blank excipient group without chitosan (1.0 g/kg). Six rats in each group, fasting for 24 h after 13 d of continuous administration, and gastric administration of anhydrous ethanol (2.5 mL/single). The blood and gastric tissue were taken out after 1.5 h to observe the pathological damage in each group. The expression of GAS, MDA, PG, epidermal growth factor (EGF) in serum and EGF, PGE2, TFF1 in gastric tissue of each group were detected. Results: Compared with the model group, the other groups can improve the gastric histopathology of rabbits with acute gastric ulcer effectively. The content of EGF in serum and EGF, PGE2, and TFF1 in gastric tissue of rabbits was increased in varying degrees, and the content of GAS, MDA, and PG in serum was all decreased in different degrees. Conclusion: SGIFT had certain therapeutic effects on rabbits with anhydrous ethanol gastric ulcer. The mechanism might be related to protecting gastric mucosa, increasing the content of protective factors, and reducing the content of attack factors.

OBJECTIVE:To analyze the blood drug monitoring results of vancomycin and clinical administration behavior and then to provide a clinical reference for its rational utilization.

OBJECTIVETo explore the expression of MMP20 in endometrial carcinoma and its clinical significance.

METHODSBioinformatics analysis was used to explore the correlation of MMP20 expression with the prognosis of the patients with endometrial carcinoma. We collected 21 pairs of fresh endometrial carcinoma and adjacent endometrial tissues to detect the expression of MMP20 mRNA using real-time PCR. We also examined MMP20 protein expressions in 134 paraffin-embedded endometrial carcinoma tissues and 34 paraffin-embedded endometrial tissues using immunohistochemistry. The correlation of MMP20 expression with the clinicopathological features and prognosis of the patients were analyzed.

RESULTSBased on TCGA database analysis, the patients with endometrial carcinoma showing an increased MMP20 mRNA expression had a significantly poorer prognosis than those with a low MMP20 mRNA expression (=0.00065). Real-time PCR analysis and immunohistochemistry confirmed the up-regulated expressions of MMP20 at both the mRNA (=0.0062) and protein (=0.005) levels in endometrial carcinoma tissues compared to the adjacent endometrial tissues. An elevated MMP20 protein expression was positively associated with FIGO stage of endometrial carcinoma (=0.014) and inversely correlated with the survival time of the patients (=0.019). The Cox regression model analysis showed that an increased MMP20 expression was an independent predictor of a poor prognosis of the patients with endometrial carcinoma (=0.067).

CONCLUSIONSHigh expression of MMP20 is a potential prognostic factor for poor outcomes of patients with endometrial carcinoma.
