OBJECTIVE The bibliometric index of papers published in Chinese Journal of Nosocomiology in sequential 11 years was analyzed by the citation method in order to get comprehensive understanding of the articles in academic quality and level.METHODS The cited articles in the journal were analyzed and evaluated using quantitative approach on the basis of the data searched from Chinese Medical Citation Index(CMCI) database developed by Medical Library of Chinese PLA.RESULTS The total cites,immediacy index and impact factors of the journal articles were turned to increase in years.Authors were widely distributed,however,mainly concentrated in Beijing,Shanghai,Guangzhou and some developed provinces as well as the affiliated hospitals of the large medical universities.CONCLUSIONS With comparatively high quality in articles which can fully reflect the scientific achievements and development in the field of nosocomial infections in China,the journal is evaluated as one of core journals in medical even in the whole scientific journal collections.

AIM: To explore the effects and mechanisms of classic prescription Jiajian Yun? Decoction(JJYND) on ventricular remodeling. METHODS: Two kinds of ventricular remodeling model were induced by injecting L-thyroxine intraperitoneally or banding abdominal aorta in rats.The effects of JJYND on heart index(HI) and concentrations of neuroendocrine factors such as serum nitric oxide(NO),myocardium angiotensin Ⅱ(Ang Ⅱ),endothelin-1(ET-1),activities of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),concentration of myocardium hydroxyproline(Hyp),cross section area of cardiomyocyte were determined. RESULTS: JJYND could significantly reduce the heart index,cardiomyocyte cross section area,elevate serum NO concentration,restrain myocardium Ang Ⅱ,ET-1,Hyp concentrations and improve myocardium GSH-Px、SOD activities. CONCLUSION: Prescription JJYND has good effects on attenuating ventricular remodeling.

Angiotensin (1-7) is an important biologically active substance of the renin-angiotensin-aldosterone system.It has vasodilatory,antiproliferative and antithrombotic effects.The functions of Ang (1-7) are often opposite to Ang Ⅱ. Ang (1-7) can be formed from Ang Ⅰ or Ang Ⅱ .Angiotensin-converting enzyme 2 is the rate-limiting enzyme of Ang(1-7).The biological effects of Ang (1-7) are mainly mediated by its receptor, the G-protein-coupled receptor Mas.

Matrix metalloproteinase (MMP) are a family of zinc-dependent endoproteinases whose enzymatic activity is directed against components of the extracelluar matrix(ECM). Their activities are inhibited by the tissue inhibitor of metalloproteinase (TIMP). MMP exerted an important role in invasion and metastasis of gastrointestinal cancer through degrading the ECM. With further research on inhibition of MMP, synthetic MMP inhibitor will have good prospects in the treatment of tumor invasion and metastasis.

Hereditary erythrocyte glucosephosphate isomerase (GPI) deficiency is thefourth most common cause of non-spherocytic hemolytic anemia. A case of GPI deficiencywas confirmed after screening a panel of 18 red cell enzymes and GSH. The GPI variantwas characterized by biochemical parameters including GPI activity in erythrocytes andplasma, low substrate activity, electrophoretic mobility, pH optimum, Michaelis constant(Km), thermostability, and substrate analogue (GAL-6-P) utilization rate. A new GPIvariant was found and was designated as GPI-Guangzhou.

Objective Through the statistical analysis on literature on asthenia cold syndrome in recent ten years,to comprehend the present situation of studies on the feature and objectivization of symptom distribution of asthenia cold syndrome.Methods Collect literature on asthenia cold syndrome from the periodicals of traditional Chinese medicine and integrated traditional and western medicine from the year 1996 to 2006.The described features and objective indices of symptom distribution of this syndrome were systematically analyzed and summarized.Results In the literature,the diagnostic criteria of asthenia cold syndrome were made mainly by the authors themselves,few referring to others',being different in the descriptions of symptom distribution.The researches on objectivization indices were scattered,most of which took the single or multiple index(es) as subject(s).Conclusion Cold limbs,tiredness,aversion to cold,and loose stools are possibly significant in the diagnosis of asthenia cold syndrome.The way of the studies on diagnostic criteria and its objectivization of asthenia cold syndrome need to be improved.

Objectiove To explore the teaching effectiveness of PBL teaching methods the teaching of cardiothoracic surgery.Methods Random clinical medical intern students 2008-2009 in our department were divided into 2 groups,with PBL teaching methods used in experimental group,and traditional teaching methods in the control group.Results The excellent and failure rates of the exam scores of the students in the experimental group were 75% and 4% respectively.while in the control group were 43% and 18% respectively.After statistical treatment,compared with the excellent and failure rates in the experimental group and in the control group,the difference is of high significance.Conclusion PBL teaching method in cardiothoracic surgery in the teaching effectiveness of teaching is better,worthy of promotion.

Aging is a complex pathological and physiological phenomenon characterized by the decline of many functions in human. Several lines of experimentation showed that the defect of the mitochondria function is one of the driving forces for the progress of aging. During the development of aging, the alteration of biology of mitochondria, the accumulation of the generation of "free radical"in mitochondria, the mutation in mitochondria genomes and the control of the progress of death by mitochondria were suggested to be a number of novel mechanisms for mitochondria in aging. The experiment data focused on the role of mitochondria in aging are reviewed.

Allogeneic peripheral blood stem cells transplantation is the most effective method for maligant hematological disease. The author reviewed the indication of acceptance of HLA mismatch kinds and the prediction of the results by selecting the measures such as pretreatment,mobilization,stem cells disposal,immunity reconstruction,graft failure management in order to improve the engraft rate.

Objective To survey the awareness of hyperuricemia in patients and medical personnel in Yuetan community.Methods By using random sampling method, 492 patients with hyperuricemia and 84 medical personnel in Yuetan community were selected for questionnaire survey.Results The rate of awareness of hyperuricemia in patients was 33.2%(1 472/4 428), and 95.5%(470/492)of them had the requirement of health education on hyperuricemia.The awareness rate of hyperuricemia in medical personnel was 73.0%(736/1 008), and 46.4%(39/84) of them thought health education on hyperuricemia as important or very important.Conclusion The awareness of hyperuricemia is insufficient in patients and medical personnel.Health education should be reinforced for community management on hyperuricemia.
