Objective To evaluate the effect of indomethacin in the prevention of post ERCP pancreatitis (PEP) .Methods The literatures and corresponding references of randomized controlled trials (RCT ) on indomethacin in the prevention of PEP were searched from Cochrane Library (Jan 1970 to June 2013) ,Pubmed(Jan 1966 to June 2013) ,EMBASE(Jan 1966 to June 2013)and China Biology Medicine disc(Jan 1978 to June 2013) .Literature screening ,data extraction and methodological quality assessment were individually performed by two researchers .The software RevMan 5 .2 of Cochrane Collaboration was used for statistical analy‐sis .Results A total of 7 trails ,2170 patients were included in this study .Meta analysis results showed:indomethacin could effec‐tively prevent from PEP (RR=0 .45 ,95% CI:0 .33-0 .60 ,P<0 .05) and Hyperamylasemia (RR=0 .51 ,95% CI:0 .37-0 .70 ,P<0 .05) compared with placebo ,and could effectively alleviate the severity of pancreatitis after ERCP (RR=0 .43 ,95% CI:0 .23 -0 .78 ,P<0 .05) .Conclusion Indomethacin could effectively prevent from PEP and Hyperamylasemia ,and could effectively alleviate the severity of PEP .

Objective To investigate the effect of salvia Miltiorrhiza on the patients with chronic allograft nephropathy.Method 20 cases were treated by the combination of salvia miltiorrhiza and routine anti-rejection therapy.Results The effect of the combination in salvia group was better than that in the control group .The significant difference was found between the two groups of the patients (P

Objective To explore the application effect of the model of clinical nursing path management in clinical nursing. Methods A comparative study was conducted of the clinical nursing paths respectively with regard to patients who had received thyroid adenoma resection and with regard to patients who had received hysteromyomectomy. Results In the experimental group involving clinical nursing path management, the average length of stay was shortened, pre operation days were reduced, and the average hospitalization expenses were lowered while the satisfaction rate of patients with thyroid adenoma rose by 2.18%, reaching 98.96% and that of patients with hysteromyoma rose by 2.87%, reaching 99.55%. At the same time, clinical nursing path management also enhanced the job satisfaction of nurses. Conclusion It is viable to adopt the model of clinical nursing path management in clinical nursing in China.

Objective To explore the application of association rules with Constraints in medical data analysis.Methods Constraints were applied in mining association rules of medical data by analyzing the characteristics of the data.An effective algorithm for mining association rules with constraints from medical data called CAMD was developed.The algorithm was applied to the analysis ofcoronary heart disease dataset.Results Assigning minimum support and minimum confidence as 0.20 and 0.60,respectively,with data from 303 cases of coronary heart dieses analyzed,8 association rules were tained.Crrelations between age,sex,electrocardiograph results,pathogeny and diagnosis of coronary heart disease were discovered.Conclusion Results from our experiments show that CAMD scans the database fewer times and has no need of pruning candidate itemsets.Thus,it greatly decrease the amount of useless rules produced and rapidly discover interesting association rules of medical data.

Objective To evaluate the clinical applicational value of color doppler flow image(CDFI)to perforation of ventricular septum resulting from myocardial infarct.Methods Before 7 cases confirmed perforation of ventricular septum though DSA,were examined by CDFI.The two results were compared to study the difference of bothes.Results All patients' results though CDFI were as the same as those though DSA,and accuracy rating was 100%.Conclusion CDFI may be applicated to early diagnose perforation of ventricular septum.

Objective To prepare and optimize formulation of ATRA liposomes. Methods ATRA liposomes was prepared by reverse evaporating method and to determine the concentration and the entrapment efficiency of ATRA liposomes by HPLC. Results The entrapment efficiency of the three ATRA liposomes formulations reached 33.98%, 42.11%, 70.34% respectively. The liposome was stable. The ATRA content of three formulations almost showed no change during the observing days. Conclusion The technique of preparing the ATRA liposomes is feasible and the method of quality control is simple and accurate.

BACKGROUND:The mechanical environment of skin tissue and spreading state of epithelial cels are closely related with the wound healing and scar formation process. OBJECTIVE:To analyze the effect of extracelular mechanical stimulation on cel spreading, to test the cel proliferation in order to analyze the effect of spreading form on cel proliferation and other physiological activities. METHODS: Cyclic sine wave mechanical stretching was exerted on immortalized human keratinocyte by using FX-4000 flexible substrate loading system, on the condition of 0.2 Hz and at frequency of 10% amplitudes. The spreading form was compared at 0, 24 and 48 hours, the cel proliferation was analyzed with flow cytometry, and the distribution of vinculin was analyzed with immunofluorescence staining. RESULTS AND CONCLUSION: human keratinocyte would keep the spreading state and could induce more cel proliferation by 24 hours mechanical stretching stimulation. Conversely, after stimulated for 48 hours, the morphology of the human keratinocyte was significantly changed, and the number of human keratinocyte in the division stage was larger than that in the static control group; under tensile stress, the distribution of vinculin was transformed from the surrounding nucleus membrane area to the cel edge. The results indicate that proper mechanical stimulate can increase cel proliferation with keeping cel spreading and adhesion state; the stimulating time of continuous cyclic stretching is the major factor to determine cel spreading morphology and adhesion regions of immortalized human keratinocyte.
