Objective To obtain the overall picture of the PubMed cited publications by major domestic medical institutions in 2013;and to learn the distribution of the number of publication,published journals,impact factor of journal,and articles published in China and overseas.Methods Information was retrieved from PubMedplus database,and the statistical analysis was conducted to assess the distribution in the number of publications,published journals and impact factor of journals by major medical institutions in China.Results Top 30 medical institutions of China in 2013 published 12178 PubMed cited papers on 1890 journals,in which 10602 papers were in English accounted for 87.06％,and 1575 papers were in Chinese accounted for 12.93％.2552 papers were Published in the top 13 journals accounted for 20.96％.PLoS One published the most of total papers.Conclusions The level of journal that published papers for major domestic medical institutions needs to be improved,and each medical institution has its own advantage in different disciplines.

Objective To explore the teaching effect of scene teaching in physical diagnostics.Methods Totally 104 clinical medicine majors of five-year program were randomly divided into two groups:experimental group (n =53) and control group (n =51).Students in experimental group were taught by scene teaching while those in control group by traditional teaching method.Teaching qualities were evaluated by final exam and questionnaire.Data of final exam were presented as mean ±SD and were calculated using student's t-test.Otherwise,statistical differences of questionnaire were calculated by Chi-square test.P ＜ 0.05 was considered statistically significant.Results Average final exam score of experimental group (80.378 ± 4.239) was better than that of control group (77.529± 4.743),with significant differences between two groups (t =3.231,P =0.002).Implementation of scene teaching method improved students self-learning ability and clinical thinking ability by 84.90％and 81.13％ respectively.Conclusions Scene teaching in physical diagnostics is superior to traditional teaching and can improve abilities of students in analyzing and solving problems.

Objective To construct an Lentiviral expression vector of pLVX‐IRES‐ZsGreen1‐MIA2 targeting to MIA2 and in‐vestigate its effect on the expression of MIA2 and growth of HCC cell line HepG2 in vitro ,observe MIA2 changes and the influence on apotheosis ,thus to provide preliminary experimental fundament for successive researching on the role of MIA2 in the pathogene‐sis of HCC .Methods The sequence of pLVX‐IRES‐ZsGreen1‐MIA2 was designed and synthesized .The pLVX‐IRES‐ZsGreen1‐MIA2 Lentiviral expression vector was constructed and then transiently transfected into HepG2 HCC cells in vitro .The proportion of pLVX‐IRES‐ZsGreen1‐MIA2 positive cells was observed under the fluorescence microscope .Then ,the expression level of MIA2 was detected by real time PCR .Moreover ,the proliferation of HepG2 cells was observed by MTT assay and colony formation as‐say .Finally ,the migration of HepG2 cells in vitro was also determined by Scratch assay .Results pLVX‐IRES‐ZsGreen1‐MIA2 Lentiviral expression vector was successfully constructed .Compared with control group (NC) ,the expression level of MIA2 was significantly decreased in transfected groups(P<0 .05);MTT assay showed that the proliferation of HepG2 cells was dramatically reduced in pIRES2‐ZsGreen1‐MIA2transfected groups(P< 0 .05);furthermore ,the number of both colony forming and migrating cells were also remarkably reduced in transfected groups(P<0 .05) .Conclusion The pIRES2‐ZsGreen1‐MIA2 can significantly re‐duce the expression level of MIA2 and inhibit the proliferation and migration of the HepG2 HCC cells in vitro .

Objective To explore the effect of empathy nursing on anxiety,depression and expectation of patients with myocardial infarction.Methods In our study,47 patients with myocardial infarction in the department of cardiology of our hospital from August 2013 to July 2014 were assigned as the control group and another 47 patients with the same disease during August 2014 to July 2015 as the study group.The control group received conventional nursing treatment and the study empathy nursing in addition to the conventional nursing.The two groups were compared in terms of anxiety,depression and expectation using Zung anxiety self rating scale (SAS),depression self rating scale (SDS) and Herth hope index (HHI).Results On admission,the patients in the two groups showed no differences in the levels of anxiety,depression and expectation (P＞0.05).After intervention,the levels of anxiety and depression in the study were significantly lower than those in the control group,but the level of expectation was higher (all P＜0.05).Conclusion Empathy nursing is effective for the relief of anxiety and depression in the patients with myocardial infarction as well as for their enhanced expectation for prognosis.

Objective To observe the effect of ambroxol on the structure of Pseudomonas aeruginosa biofilm (BF) in an established biofilm model in vitro. Method Mature BF was formed after 7 days′ culture of Pseudomonas aeruginosa on plate. The BF structure was observed by scanning electron microscope (SEM). The parameters of BF structure were analyzed though pictures from confocal laser scanning microscopy (CLSM) with Image Structure Analyzer (ISA) software. Fluorescence intensity of the viable bacteria in BF treated by ambroxol alone and together with ciprofloxacin were determined with fluorescence microscopy. Results After the treatment of ambroxol, the BF was destroyed and the matrix outsides became thin and abnormal compared with the control by SEM, and small amount of bacteria dispersed. The results of ISA showed that with the treatment of 2 mg/ml ambroxol, BF was decreased in thickness, average diffusion distance (ADD) and textual entropy (TE) were decreased in comparison with the group without ambroxol treatment (P

Objective: To investigate the changes of gallbadder motive function in diabetics. Method: The size of gnllbadder,recovering rate,echo and half-empty time after fat food were compared and statistically analyzed between 22 healthy individuals and 20 diabetics with ultrssonograph. Results:The gallbadder recovering rate was similar between the healthy individuals and diabetics (P>0.05), but the rate of cholecystitis (30%) and choletethiasis (35%) of diabetics were higher than those in healthy individuals, the gallbadder half-empty time after fat food was obviously slower in diabetics (46.1+12.9 min)than those healthy individuals (27+4.4 mmin). Conclusions: The diabetics had obvious gallbadder motive funciion obstruction and higher rates of chronic cholecystitis and choletethiasis with ultrasonograph observations.
