China Pharmacy 2007;0(25):-
OBJECTIVE: To study the protective effects of nimesulide, a COX- 2 selective inhibitor on experimental gastric ulcer in rats. METHODS: The gastric ulcer model was established in rats by intragastric administration them with indometacin, 5 min later, which were assigned to receive nimesulide at different dosages ( 200, 100, and 50mg? kg- 1) , 6h later, all the rats were sacrificed. The primary outcome measures were the area of ulcer, levels of SOD, MDA, and GSH in sera and gastric mucosa. RESULTS: As compared with model group, in nimesulide ( at different dosage) groups, the area of ulcer was markedly decreased, level of MDA was decreased while activities of SOD and GSH were increased ( P
2.Result analysis of second duplication checking in the accepted papers for Chongqing Medical Journal
Chongqing Medicine 2013;(29):3476-3478
Objective Using second duplication checking to prevent academic misconduct of accepted papers ,and to improve the academic quality of journals for the consolidating credibility of academic journal and brand establishing .Methods Academic Mis-conduct Literature Check(AMLC)system developed by CNKI was applied to check possible academic misconduct of 90 accepted pa-pers for Chongqing Medical Journal ,then the contribution time ,duplication checking time ,words repetition percentage of the accept-ed papers with academic misconduct and similarity literature were analyzed compared with the source papers .Results After chec-king 90 accepted papers ,9 of them were suspected with academic misconduct ,including 5 papers with 30 .1% -40 .0% of coinci-dence rate ,1 paper with 40 .1% -50 .0% of coincidence rate ,and 3 papers with more than 50 .1% of coincidence rate .Most of the academic misconduct were multiple contribution of same manuscript or duplicate publication .Conclusion To avoid the multiple con-tribution of the same manuscript or duplicate publication ,we should shorten peer review and publishing period ,carry on multi-dupli-cation checking ,punish academic misconduct ,and work together with other sci-tech periodicals to eliminate academic misconduct .
3.Study on Quality Standard for Chuanxiong
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(11):-
Objective To improve the quality standard for Chuanxiong by studing the method of discriminating Chuanxiong. Methods Chuanxiong was identified by TLC. The content of ferulic acid in Chuanxiong was determine by HPLC. The Agilent Eclipse XDB-C18 (4.6 mm?150 mm, 5 ?m) was used, mobile phase was methanol-1% acetic acid solution (21∶79), flow rate was 1.0 mL/min, detection wavelength was 320 nm. Results The TLC spots developed were fairly and simply identical. HPLC was accurate and reproducible. Ferulic acid showed a good liner relationship at range of 0.042 5~0.382 5 ?g, the average recovery was 97.10% (RSD=1.31%). Conclusion These methods can be used to control the quality of Chuanxiong effectively.

Egr-1 is an important transcription factor, which regulates at least 30 kinds of gene expression. Egr-1 couples extracellular signals to long-term responses by altering expression of Egr-1 target genes. So egr-1 can directly or indirectly affect cell differentiation,apoptosis,immune response,injury and repair. This article reviewed the progress in Egr-1 and the lung disease.
5.Local Angiogenesis and Neurological Functional Recovery After Cerebral Ischemia
International Journal of Cerebrovascular Diseases 2006;0(10):-
Cerebral ischemia activates endogenous angiogenic factors,and increase microvessel density and form new capillaries in ischemic brain tissues.Exogenous angiogenic factors can more effectively promote angiogenesis and the establishment of collateral circulation in ischemic regions and peripherial tissues,improving local blood supply and reducing infarct size.The further study of the mechanisms and methods in promoting regional angiogenesis after cerebral ischemia will contribute to improve neurologic deficit.

Objective To investigate the correlation of serum ereatine kinase iseenzyme-MB (CK-MB) and recent cardiac events(30 days, 180 days) and late cardiac events (360 days) in patients with acute coronary syndrome (ACS). Methods Serum creatine kinase (CK) and CK-MB in 168 patients with ACS were measured, and these patients were divided into four groups according to the levels of CK and CK-MB. The occurrence of cardiac events analysis of CK and CK-MB was followed up for 30, 180 and 360 days and the relationship between the occurrence of cardiac events and the levels of CK and CK-MB were studied. Results There was statistical correlation between increased CK-MB and abnormal ECG Q wave, ST segment change (P< 0.05), 168 patients had followed up 30, 180 and 360 days, in which cardiac events happened in 57 common patients (64 examples), 27 examples (16.1%) happened in the recent cardiac event, and 37 examples(22.0%) happened in the late cardiac event. The cardiac event and CK-MB elevation had statistical correlation (P<0.05). Conclusion ACS patients with increased CK-MB levels prompt a poor prognosis, and could be an independent indicator of recent and late cardiac events in patients with ACS.

Objective To study the clinicopathological characteristics of complicated Kaposi's sarcoma after renal transplantation.Methods Five cases of complicated Kaposi's sarcoma after kidney transplantation were studied by histopathological immunohistochemical and ultrastructural observations.Results Of the 5 Kaposi's sarcoma patients,2 had multiple amaranthine dermal plaques starting on the legs,one had lymph node hypertrophy all over the body,and others had inguinal lymph node and adenoid hypertrophy. Histopathologically,these angiomatous lesions had characteristic areas of spindle cells within which erythrocytes were enmeshed.Admixed in these lesions were hyaline bodies and hemosider-laden,phagocytic cells.Immunohistochemical and ultrastructural studies revealed that this tumor was derived from vasofomative mesenchyme with multipotential capabilities.It was found that the epithelia and spindle cells were positive for Vimentin,CD-31,CD-34 and Ⅷ-RAg.Conclusion Complicated Kaposi's sarcoma after kidney transplantation can be diagnosed by combination of clinical manifestations and histopathological examinations with immunohistochemical and ultrastructural observations.

Objective To explore the curative effect of family -based socialization management on patients with hypertension in community .Methods A total of 116 patients with hypertension were randomly divided into ob-servation group and control group , 58 patients in each group .Both groups received conventional drug treatment .The control group was given routine chronic disease management and the observation group implemented social manage -ment(patients, families, doctors).Blood pressure(BP),lifestyle and psychological condition were evaluated , and the serum triglyceride ( TG) , low density lipoprotein ( LDL) and homocysteic acid ( Hcy) were detected after one year . Results Blood pressure of patients was dropped significantly in the two groups , as compared with the control group . The BP of patients in the observation group was declined more obviously , the BP up to standard rates , control rates and treatment compliance were raised , the mode of life and mental status were improved obviously , and the serum contents of TG, LDL and Hcy were decreased significantly (p<0.05).Conclusion The use of hypotensorscombined with fam-ily-based social management can effectively help patients to control their blood pressure , raise treatment compli-ance, establish a healthy life style and improve their mental status .The mode is worth of spreading in community .
