ABSTRACT
OBJECTIVE To study the effect and potential mechanism of eriodictyol on non-alcoholic fatty liver disease （NAFLD）. METHODS Sixteen C57BL/6J mice were randomly divided into control group， NAFLD model group， and eriodictyol low-dose and high-dose groups （50， 100 mg/kg）， with 4 mice in each group. Except for control group， the other groups were fed with high fat diet to induce NAFLD model. After four weeks of preprocessing， they were given relevant medicine intraperitoneally （0.01 mL/g）， once a day， for 6 consecutive weeks. The body weight and liver weight of mice were measured， and the pathological damage of liver tissue in mice was observed. The levels of aspartate aminotransferase （AST）， alanine aminotransferase（ALT）， and triglycerides （TG） in serum， as well as the protein expressions of nuclear factor-erythroid 2-related factor 2 （Nrf2） and heme oxygenase-1 （HO-1） in liver tissue were determined. In vitro NAFLD model was established by using 0.5 mmol/L oleic acid （OA） in HepG2 cells. Normal control group， NAFLD model group and eriodictyol low-， medium- and high-concentration groups （50， 100， 150 μmol/L） were set up. HepG2 cells in drug groups were treated with eriodictyol for 24 h at the time of modeling. The lipid deposition was observed in cells， and the levels of TG， malondialdehyde （MDA） and reactive oxygen species （ROS） as well as the phosphorylation levels of the mitogen-activated protein kinase （MAPK） signal pathway related proteins [extracellular signal-regulated kinase （ERK）， c- Jun N-terminal kinase （JNK）] and the protein expressions of Nrf2 and HO-1 were all determined. RESULTS In the in vivo experiment， compared with the NAFLD model group， the body weight， liver weight， the serum levels of AST， ALT and TG were all decreased significantly in eriodictyol low- and high-dose groups （except for serum level of AST in eriodictyol low-dose group） （P＜0.01）； liver lipid deposition was reduced significantly and the protein expressions of Nrf2 and HO-1 in liver tissues were further up-regulated （P＜0.01）. In the in vitro experiment， compared with the NAFLD model group， the lipid deposition in hepatocytes was reduced in eriodictyol low-， medium- and high-concentration groups （P＜0.01）， and the levels of ROS， MDA and TG were down-regulated （P＜0.05 or P＜0.01）； the phosphorylation levels of ERK and JNK were significantly down-regulated （P＜0.01）， while the protein expressions of Nrf2 and HO-1 were up-regulated significantly （P＜0.01）. CONCLUSIONS Eriodictyol can inhibit MAPK signaling pathway and activate Nrf2/HO-1 signaling pathway to alleviate NAFLD.
ABSTRACT
Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.
ABSTRACT
Objective To observe the clinical efficacy of Bu Shen Tiao Qi(supplementing the kidney and regulating qi) needling in treating perimenopausal syndrome.Method Fifty patients were randomized into two groups, 25 cases each. The treatment group was intervened by Bu Shen Tiao Qineedling combined with electroacupuncture, while the control group was by shallow needling plus sham electroacupuncture. Kupperman Index (KI) wasobserved respectively before treatment, after 2-week and 4-week treatment, and in the 4-week follow-up study. The differences of scores and improvements of the 13 symptoms listed in KI were calculated.Result The total effective rate was 92.0% in the treatment group versus 44.0% in the control group; in the treatment group, the KI scores after 2-week treatment and in the 4-week follow-up study were significantly different from that before treatment (P<0.05), and a more significant difference was found after 4-week treatment (P<0.01); the between-group differences were statistically significant in comparing KI (P<0.05).Conclusion Bu Shen Tiao Qineedling can produce a satisfactory efficacy in treating perimenopausal syndrome.
ABSTRACT
Objective To investigate the clinical efficacy of liver-soothing and spleen-reinforcing acupuncture in treating functional constipation.Methods Sixty patients with functional constipation were randomly allocated to treatment and control groups, 30 cases each. The treatment group received liver-soothing and spleen-reinforcing acupuncture and the control group, oral administration of prucalopride succinate tablets. The number of complete spontaneous bowel movements (CSBM), the number of spontaneous bowel movements (SBM), constipation symptoms (defecation time, defecatory difficulty and fecal characters) scores and The Patient Assessment of Constipation Quality of Life (PAC-QOL) score were recorded in the two groups before and after two and four weeks of treatment. The clinical therapeutic effects were compared.Results After two weeks of treatment, there were statistically significant pre-/post-treatment differences in CSBM and SBM in the treatment group (P0.05). After two and four weeks of treatment, there were statistically significant pre-/post-treatment differences in constipation symptoms scores in thetwo groups (P0.05). The total efficacy rate was 80.0% in the treatment group and 73.3% in the control group; there was no statistically significant difference between the two groups (P>0.05).Conclusions Liver-soothing and spleen-reinforcing acupuncture has a marked therapeutic effect on functional constipation. It produces a quick effect with high safety.
ABSTRACT
Endoscopic Sphincterotomy (EST) is more popular because of slight trauma and early recovery,therefore,its complications are always neglected,and the abuse of EST occur now and then.This paper summarized the applications of EST and analyzed its complications in recent 10 years in our country,It demonstrates that EST should been correctly treated and appropriately used.

There are different opinion in different scholar about the choice of surgical treatment. This paper summarizes the surgical treatment and operative indication of hepatic hemangioma.
ABSTRACT
Objective To study the influences by a Cyelin-dependent kinase inhibitor Roscovitine on cell cycle in mitotic hepatoma carcinoma cell SMMC-7721. Methods Microscope,MTT, flow cytometry and R-T PCR were used to observe the effects of Roscovitine on morphology, proliferation, cell cycle, apoptosis and the mRNA expression of CDK2, Caspase-3, bcl-2 in SMMC-7721 cells. Results Roscovitine inhibited the proliferation of SMMC-7721 cells in dosage and time dependent manner and induced apoptosis. Flow cytometry showed the ratio of G0, G1 increased. R-T PCR showed that the expression of bcl-2 reduced, Caspase-3 increased. Conclusion Reseovitine can inhibit the growth, proliferation, block the cell cycle at G0/G1 and promotes apoptosis of mitotic SMMC-7721 cells, and the mechanism of apoptosis is dependent on the activity of bcl-2 and Caspase-3.
