In recent years,the basic research on liver fibrosis has been progressed rapidly.This article briefly reviews the cellular and molecular mechanisms of liver fibrosis,including the origin of myofibroblasts,immune regulation,autophagy,and epigenetic regulation,and introduces several new therapeutic targets.More and more evidences show that successful removal of causes is the most important antifibrotic therapy.At present,although the antifibrotic drugs acting on different targets have been emerging,most of them are still in the early stage of research and development,and well-designed clinical trials are needed to confirm their clinical efficacy.

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 observe the effect of electroacupuncture on hand dysfunction after stroke. Methods Forty hemiplegic patients after stroke were selected from a multi-center large-scale trail, belonged to rehabilitation group (n=20) and electroacupuncture group (n=20), who accepted routine rehabilitation and additional electroacupuncture, respectively, for six weeks. They were assessed with Brunnstrom Grade, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT) and modified Barthel index (MBI) before treatment, two, four and six weeks during treatment, and twelve weeks after treatment. Results There were differences between two groups in scores of FMA, WMFT and total time to complete WMFT twelve weeks after treatment (t>1.900, P<0.05). There was no difference between two groups in scores of MBI and Brunnstrom Grade (t=0.532, Z<1.79, P>0.05), but electroacupuncture group seemed to improve more. Conclusion Elec-troacupuncture may improve the muscle strength for patients in flaccid paralysis, and promote the recovery of hand function for patients af-ter stroke.

In order to solve some limitations and difficulties in guiding the practical work of determination and classification of the areas of high water iodine and the endemic areas of iodine excess goiter (GB/T 19380-2003),we carried out the revision on the original standard from 5 aspects such as the name,normative reference file,the definition and the technical indicators of classification of high iodine areas and the endemic areas of iodine excess goiter,such as sampling method in appendix and so on,and worked out the standard of definition and demarcation of water-borne iodine-excess areas and iodine-excess endemic areas.Enforcement of the new standard will bring important social benefits.

OBJECTIVE:To establish a RP-HPLC method to determine the content of ofloxacin in compound ofloxacin eye drops METHODS:Using Shim-pack ODS as fixed phase,a mixture to citric acid(0 05mol/L)-acetonitrile-ammonium acetate(0 5mol/L)-0 3% phosphoric acid(78∶22∶1∶3)as mobile phase,and detecting wavelength:293nm,flow rate:1 0ml/min RESULTS:The linear range of ofloxacin was 8 12?g～40 6?g(r=0 9 996,n=5) The average recovery was 99 29% and RSD(n=6)was 0 57% CONCLUSION:The method is rapid,simple and accurate

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 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.

This paper affirms that physician-patient relationship is the most important and fundamental relationship in medical activities.But nowadays there are some unpleasant factors arising in the physician-patient relationship,which have become severe intractable problems and heated social issues to be resolved as soon as possible in the development of Chinese society and healthcare career.Traditional Chinese Medicine contains a lot of information about medical ethics and humanism spirit of medicine.There are also many theories on how to build up a harmonious physician-patient relationship and many viable methods to solve the problems.Analysis of the physician-patient relationship nowadays and exploration of the T.C.M quintessence will help to build up a harmonious physician-patient relationship with Chinese characteristics for the construction of a harmonious society.
