Objective: To observe the morphological changes of enteric deep muscular plexuses interstitial cells of Cajal (ICC-DMP) in rats with multiple organ dysfunction syndrome (MODS). Methods: Forty Wistar rats were randomly divided into control group and MODS model group. The enteric ICC-DMP network was observed using c-kit immunohistochemical staining with whole-mount preparation technique and confocal laser scanning microscopy , and the ultraslructural features of ICC-DMP was evaluated using transmission electron microscope. Results: Compared with those in control group, the distributions and densities of intestine ICC-DMP in MODS group were significantly decreased (P < 0. 05) , the ICC-DMP network was disrupted and the ultrastructural features of ICC-DMP were severely damaged. Conclusion: The ICC-DMP network was severely damaged in rats with MODS, and the mechanism of gastrointestinal dysmotility in MODS may be related to the morphological changes of ICC-DMP.

Objective To verify the best treatment strategy in reducing prostate specific antigen (PSA) progression and death rate in patients with locally advanced prostate cancer by a meta-analysis. Methods The literature search strategy was followed according to the Collaborative Review Group search strategy. Published data of randomized clinical trials comparing radical prostatectomy (RP) plus adjuvant therapy to either RP alone or other treatment were analyzed. Both fixed effect model and randomized effect model were applied and odds ratio (OR) with its 95% confidence interval (95% CI) was also used as the effect size 'estimate. Results Eight clinical trials were chosen with total in-volved cases of 3826. There were 5 trials compared post radical prostatectomy plus adjuvant hormonal therapy with radical prostatectomy alone. PSA progression was used as the indicator of progression and the combined OR was 0.86 (95%CI 0.48-1.56). There were 3 trails compared the combination of radical prostateetomy with hormonal therapy and radical prostatectomy alone. Disease specific death rate was used as the evaluating criteria and the OR was 0.72(95%CI,0.51-1.02). Conclusion RP plus adjuvant hormonal therapy can reduce PSA progression of patients with locally advanced pros-tate cancer, but it has no significant effect on disease specific death rate.

Objective To systematically evaluate the study of animal surgery course among medical students with different majors and languages so as to provide evidences for further improve-ment education quality. Methods Ten majors and two kinds of international medical students (in total of 1 105 students;2009 grade)of Southern Medical University were subdivided into five groups ac-cording to the relationship with clinical operative manipulation. Quality of experimental animal surgery education was tested respectively. Then SPSS 13.0 was used to statistically evaluate and analyze the data. Measurement data between two groups were compared by t-test,multi-group analysis of variance between groups was conducted using one-way ANOVA. Ranked data between groups were compared using non-parametric Mann-Whitney U rank sum test. Merits and demerits of the curriculum were dis-cussed by combing statistical results with in-class condition to provide evidences for further improve-ment. Results There was no significant difference between clinical group and clinical professional group in aseptic technique and operation skills (P=0.739),but scores of the two groups were signifi-cant higher than that of associate group (P=0.004). Moreover,scores of international students who passed Chinese TOEFL were significant higher than the others (P=0.001). Differences between groups existed predominantly in the animal surgical practice rather than in basic theory or knot and sterilized methods. Conclusions For students with different majors and languages,different teaching key points should be paid attention to. Basic surgery techniques might be emphasized on for students with associ-ate clinical major and foreign students with poor Chinese language.

Objective To evaluate the effect of automatic early warning information system on the response of malaria elimi-nation in Jiangsu Province through the operation of the national automatic early warning system of infectious diseases. Methods The malaria early warning information was collected from the automatic early warning information subsystem in the national infor-mation system for diseases control and prevention. Malaria early warning signals were analyzed from September 1 to December 31, 2012. The statistical analysis was conducted for the completion rates of case investigation within 3 days before and after the applica-tion of malaria early warning information system. Results Jiangsu Province received 85 mobile phone short messages(SMS)of malaria case from early warning system from September 1 to December 31,2012. After judgments,23 cases were deleted includ-ing 8 repeated cases and 15 cases that were excluded through the microscopy examination and epidemiological investigation by the confirmation of county CDC. From July to December in 2012,the monthly completion rates of case investigation within 3 days were 55.56%,78.57%,90.00%,100%,100%and 100%,respectively. The completion rates of case investigation within 3 days in Ju-ly,August,September and October were significantly different by χ2 test(χ2=10.66,P<0.05). The completion rates of foci in-vestigation and action within 7 days in Jiangsu Province were all 100%from July to December in 2012. Conclusions The comple-tion rates of case investigation within 3 days are associated with SMS from the early warning system. The malaria warning system from the national infectious diseases can effectively improve the response to malaria cases for primary CDC. It also plays an impor-tant role for the timely confirmation and diagnosis of malaria cases.

Objective To analyse the epidemic characteristics and control measures of malaria in Jiangsu Province during the past fifty years, evaluate the control effect and explore the current appropriate control strategy and measures. Methods The historical data about malaria cases and control measures from 1951 to 2008 in Jiangsu Province were collected, and the effects of malaria control in different stages were assessed. Results The integrated control measures with emphasis on the control of infectious source were adopted during the stage of two outbreaks of malaria. In the stage of basical elimination of malaria, the comprehensive measures with emphasis on the vector control in the areas of Anopheles anthropophagus were adopted, and the measures with emphasis on the surveillance of infectious source surveillance and early treatment of malaria in other areas were adopted. In the stage of consolidation, the measures including the surveillance of infectious source and management, surveillance of vector and epidemic situation, management of floating population, etc, were adopted. The malaria incidence dropped from 2 495/10 000 in 1960 to 0.09/10 000 in 2008, and was under 1/10 000 in all the counties of Jiangsu Province during the past 2 years, which demonstrated the various measures were feasible and effective in different stages of malaria. Conclusions Malaria has been controlled effectively in Jiangsu Province, however, the improvement of early diagnosis and norm treatment of malaria cases, the enhancement of health education and promotion, as well as the malaria surveillance and management among floating population, are still necessary for achieving the goal of malaria elimination.
