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 understand the malaria epidemic situation and characteristics in Jiangsu Province in 2013,so as to provide the evidence for formulating and adjusting effective malaria elimination strategies and measures. Methods The re-ported malaria cases from the Internet Reporting System and the epidemiological data of malaria in Jiangsu Province were collect-ed and analyzed. Results A total of 341 malaria cases were reported in Jiangsu Province in 2013 with the incidence of 0.050/10 000,which increased by 72.22% compared with that in 2012(198 cases). All the cases were imported from other countries including one infected by blood transfusion resulted from imported infection. The cases were mainly distributed in Li-anyungang City(15.84%,54 cases),Nantong City(14.08%,48 cases),Yangzhou City(14.08%,48 cases),Huaian City (11.44%,39 cases)and Yancheng City(8.50%,29 cases). All the cases were confirmed in Jiangsu Provincial Reference Labo-ratory and there were 286 cases of Plasmodium falciparum,8 cases of P. vivax,9 cases of P. malariae,30 cases of P. ovale and 8 cases of mixed infections. Conclusions There were no local malaria cases reported from Jiangsu Province in the last two years which reflected effective achievements of malaria elimination. However,the situation of imported malaria is more serious and the species of infected plasmodium are more diverse. Imported malaria from other countries remains the key of malaria con-trol in Jiangsu Province.

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.
