Objective To study the effect of gastrin, motilin of chronic atrophic gastritis model in rats by acupuncturing at back-shu points. Methods 60 SD rats were randomly divided into blank control group, model control group, omeprazole group, back-shu points group, with 15 rats in each group, and to establish the model of chronic atrophic gastritis by irregular diet that given rats odd and even days. The blank control group, model control group were fed with normal saline, 2ml/time, 1 time/day. The omeprazole group was given oral gavage(Omeprazole 0.44 mg/kg, Clarithromycin 6.92 mg/kg, Metronidazole 7.6 mg/kg), 1 time/day. Back-shu points group received acupuncture at “Geshu”“Ganshu”“Pishu”“Weishu”“Shenshu”, retaining 15 min, 1 time/day. After 30 days, the content of ELSIA was used to detect the serum gastrin, motilin. Results ①GAS of model control group(54.25±5.70)pg/ml was significantly decreased compared with blank control group(66.63± 5.99)pg/ml, the difference was statistically significant (P<0.05). Compared with the model control group, GAS content of omeprazole group(62.70±8.55)pg/ml and back-shu Points group(66.27±3.79)pg/ml were higher, showed significant differences(P<0.05). ②MOT of model control group(223.60±17.83)pg/ml was significantly increased compared with the blank control group(188.45 ± 8.90)pg/ml, the difference was statistically significant(P<0.05). MOT of omeprazole group(200.16 ± 4.38)pg/ml and back-shu Points group(190.11±10.04)pg/ml were lower than those in the model control group, there was statistically significant difference(P<0.05). Conclusion Acupuncturing at back-shu acupoints can increase the content of GAS, reduce content of MOT, regulate gastrointestinal hormone in rats of chronic atrophic gastritis model.

Objective: To study the constituents from the sea cucumber Holothuria nobilis. Methods: The compounds of the sea cucumber were separated by multi-chromatography and their structures were elucidated by physico-chemical and spectral analyses. Results: Two new triterpene glycosides were isolated and their structures have been deduced by extensive spectral analysis (IR, 2D-NMR, and ESI-MS) and chemical structures as 3-O-{3″″-O-methyl-β-D- glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→4)-β-D- quinovopyranosyl-(1→2)-4′-O-sulfate-β-D-xylopyranosyl} -holosta-22, 25-epoxy-9-ene-3β, 12α, 17α, 25β-tetraol- sodium salt (nobiliside I, 1) and 3-O-{β-D-quinovopyranosyl-(1→2) 4′-O-sulfate-β-D-xylopyranosyl}-holoshillaside 18 (16)-lactone-22, 25-epoxy-9-ene-3β, 12α, 17α-triol sodium (nobiliside II, 2). Conclusion: Two aglycons are both new compounds named nobiliside I and nobiliside II.

Objective: To study the constituents from the sea cucumber, Stichopus variegatus. Methods: The crude saponins of S. variegatus were desulfated with pyridine-dioxane (1:1), the desulfated products were separated by multi-chromatography to afford two compounds. Results: On the basis of chemical methods and spectral evidences, especially 2D-NMR and ESI-MS, these two compounds were identified as 3-0-[β-D-xylopyranosyl-(1→2)-4′-O- sulfate-β-D-xylopyranosyl]-holosta-9-ene-3β,12α,17α, 25β-tetraol sodium salt, named as variegatuside A (1) and 16β-acetoxy-3-O-β-D-xylopyranosyl-holosta-22,25-epoxy-9-ene-3β, 12α,17α-triol, named as variegatuside B (2). Conclusion: Compounds 1 and 2 are new compounds.

As a member of homeobox gene family,HOXA5 is expressed in many organs and can regulate gene expression,cell differentiation and morphogenesis.Its structure and (or) function abnormalities are closely related to the development of leukemia,breast cancer,brain hemangioma,hepatocellular carcinoma and so on.Researching the relationships between HOXA5 and tumors contributes to cancer diagnosis,treatment and prevention.

Bioglass is one of the most important inorganic biomedical materials and is widely used in clinic. Orthopedists and researchers pay more and more attentions to bioglass due to its excellent biocompatibility and bioactivity. This paper introduces the current research status and development of bioglass in bone repairing,bone tissue engineering, anti-infection drug delivery material and interventional therapy. Brief review is given to the potential application of bioglass in orthopaedics.

Papers on electronic health record ( EHR) were retrieved from CNKI core journals database and CNKI patents full-text database.The papers on HER and patent literature were comparatively analyzed by co-words clus-tering analysis, which showed that technologies used in community health service, remote medical treatment, HL7 and XML are the promise technologies used in EHR.

Objective To understand the status of the improper avademic behavior in medical journal,and to explore the prevention measures.Methods Total of 1 321 article in Zhongguo Yishi Jinxiu Zazhi were included in this study.Similarity detection system of Wanfang data and Google and baidu search engine were used to duplicate checking.The suspected existence of contributions for the improper avademic behavior,to check the whole paper of relevant original manuscript,and analyzed the characteristics of improper avademic behavior.Results One hundred and forty-five improper avademic behavior were found in 1 321 articles,accounted for 11.0％.The similarity of 58 paper were higer than 50.00％,accounted for 40.0％.Among them,the similarity of 10 papers were more than 90.00％,8 papers were 80.00％-89.99％,12 papers were 70.00％-79.99％,13 papers were 60.00％-69.99％,15 papers were 50.00％-59.99％,13 papers were 40.00％-49.99％,accounted for 9.0％,24 papers were 30.00％-39.99％,accounted for 16.6％,50 papers were 20.00％-29.99％,accounted for 34.5％.In 145 papers,copying accounted for 35.2％ (51/145),data forge or tamper accounted for 28.3％(41/145),breach of medical ethics and academic moral accounted for 28.3％ (41/145),fraud accounted for 6.9％ (10/145),a draft cast more accounted for 1.4％ (2/145).Original articles in the clinic were 92 papers,accounted for 63.4％;case reports were 28 papers,accounted for 19.3％;review were 25 papers,accounted for 17.2％.76 papers with a single author,accounted for 52.4％;38 papers with two authors,accounted for 26.2％,31 papers with more than three authors,accounted for 21.4％.Conclusions Contributions of suspected improper avademic behavior ratio is higher,and have certin characteristic.Medical journal editors should strengthen the responsibility consciousness,improve the ability to identify misconduct papers.

Objective To investigate the changes in serum leptin and adiponectin levels and their significance in patients with chronic hepa-titis B virus (HBV)infection.Methods One hundred and twenty -five patients with chronic HBV infection (44 HBeAg -positive cases, 31 HBeAg -negative cases of chronic hepatitis B,23 chronic HBV carriers,and 27 inactive HBsAg carriers)were recruited in the present study.Fifty -five healthy people served as the control group.Blood samples were collected at 8 to 9 AMof the next morning after overnight fasting.Blood glucose,blood lipids,renal and liver function parameters,fasting insulin,serum HBV markers,and HBV DNA concentration were determined,and HOMA -IR was calculated.Serum levels of leptin and adiponectin were measured by ELISA.Continuous data were expressed as mean ±SD,and Student′s t -test,analysis of variance,linear regression analysis,and multiple regression analysis were ap-plied in the analysis of all experimental data.Results There were no significant differences in serum levels of leptin and adiponectin be-tween patients with chronic HBV infection and the control group (P =0.480;P =0.321),even after stratification by gender (males:P =0.210 /0.895;females:P =0.404 /0.066).After patients with chronic HBV infection were divided into subgroups by HBeAg status,HBV DNA,or ALT level,there were no significant differences in serum levels of leptin and adiponectin between groups (leptin:P =0.820 /0.296 /0.212;adiponectin:P =0.268 /0.760 /0.224).Conclusion For patients with chronic HBV infection,infection status and viral replication level are not significantly correlated with serum levels of leptin and adiponectin.
