Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

On the basis of above-mentioned discussions,the authors then open up prospects for research and suggest that the concept and the research method,the factors,the influences,the prevention,and intervention strategies of the deviant behaviors online and the relationship between deviant behaviors online and offline are important topics to be explored in the future.

It is critical to preventing gut-originaltel infection to attenuate bacterial and/or endotoxin translocation, maintain bacterial balance, improve gut mucosal barrier function and elevate local immunity. Probiotics beneficially affect the host by improving its intestinal microbial balance, by preventing gut mucosal barrier breakdown and bacterial translocation, by modulating immunity,and by promoting gut movements and absorption. The role and new progress of probiotics in enteral nutrition are reviewed .

Objective: To explore the relationship among adolescents’ ego identity,internet service preference and pathological internet use. Methods: A survey research method was adopted in which questionnaires were administered to 404 middle school students from Junior I to Senior Ⅱ city. Results: The relationship between ego-identity achievement and pathological internet use was significantly negative(r=-0.19,P

Objective To evaluate the effect of the cyclooxygenase (COX-2) inhibitor celebrex on the growth of VX_2 renal carcinoma in a rabbit model in order to provide the basis for clinical application. Methods A rabbit model of VX_2 renal carcinoma was reproduced. The effect of COX-2 inhibitor celebret on tumor growth was observed. Results Compared with control, the growth of VX_2 renal carcinoma was remarkably retarded after celebrex treatment for 2 and 3 weeks. The difference between the two groups was signiticant (P

Objective To investigate the relation between the prognosis and complication of patients with severe viral hepatitis (SVH) Methods The incidences of different complications in 573 patients with SVH were analyzed The survival rates of SVH patients with different complications were compared Results Complications were diagnosed in 77 8% SVH patients The incidences of hepatic encephalopathy, infection, brain edema, gastrointestinal hemorrhage, and hepatorenal syndrome were 50 4%, 34 6%, 30 2%, 22 2%, and 21 8%, respectively The survival rate of SVH patients without complications was 78 7%, significantly higher than that of patients with complications (13 7%, P

Objective To explore the effects of curdione on cognitive function and expression of inflammatory factors in the hippocampus after partial hepatectomy in aged mice.Methods The animals were divided into control group, sham group, operation group, and high-, medium-and low-dose curdione groups.The model of partial hepatectomy in aged mice was established according to the method reported in literature.The levels of SOD, MDA, CAT and GSH-Px in the hippocampus were detected by enzyme-linked immunosorbent assay (ELISA), while the expressions of NF-κB, IL-1β, IL-6 and TNF-α were measured by Western blot.Results The escape latency was significantly increased (P<0.01), and the number of platform-site crossovers was significantly decreased in operation group (P<0.05).Compared with those in operation group, curdione significantly decreased escape latency and increased platform-site crossovers (P<0.05, P<0.05).The levels of SOD, CAT and GSH-Px in the hippocampus were significantly decreased (P<0.05) and the content of MDA was significantly increased after partial hepatectomy (P<0.01), and these were reversed by curdione (P<0.05, P<0.05, respectively).The expressions of NF-κB, IL-1β, IL-6 and TNF-α protein were significantly inhibited by curdione (P<0.05).Conclusion Curdione can significantly improve cognitive dysfunction after partial hepatectomy in aged mice and the mechanism may be related to its inhibition of oxidative stress, inhibition of NF-κB activation and reduction of inflammatory cytokines IL-1β, IL-6 and TNF-α in the hippocampus.

Objective To study the effects of Danshen co-microemulsion (Co-ME) in treatment of acute myocardial ischemia induced by pituitrin in rats. Methods The experimental model of myocardial ischemia was produced by injecting pituitrin into the sublingual vein of rats. The serum level of malonaldehyde (MDA) and the activities of phosphocreatine kinase (PCK), lactate dehydrogenase (LDH), and erythrocuprein (SOD) were examined in Co-ME, salvianolic acid microemulsion, tanshinone microemulsion, tanshinones suspension and blank microemulsion groups 30 min after injection of pituitrin. Results Co-ME, tanshinone microemulsion, salvianolic acid microemulsion and tanshinone suspension all improved myocardial eschemia to some extent; besides, they also decreased PCK, LDH activities and MDA content, and increased SOD activity. The therapeutic effect of Co-ME group was superior to those for the tanshinone microemulsion and salvianolic acid microemulsion groups, and significantly better than that of tanshinone suspension group (P<0. 05). Conclusion Microemulsion system can greatly promote the absorbance and bioavailability of tanshinone, displaying a therapeutic effect for acute myocardial ischemia. Salvianolic acids combined with tanshinones can promote the therapeutic effect.
