Relevant projects carried out within the Yangtze River economic belt on the impact of schistosomiasis epidemic and transmission are important issues for ecological priority in the process of implementing the strategy. The key problems of schistosomiasis epidemic risk,epidemic happening repeatedly,difficulty of rehabilitating Oncomelania hupensis snail control and schistosomiasis prevention forest,lag of evaluation system and platform construction,lack of basic research,et al. were ana-lyzed in the Yangtze River economic belt taking ecological priority as the basis in this paper. Then corresponding countermea-sures to these challenges were put forward so as to provide the reference for the national forestry schistosomiasis control pro-grams,which include:execution of the comprehensive prevention and control strategy,scheming of the new round of forestry schistosomiasis control programs,strengthening schistosomiasis prevention and control,promoting productivity in existing forest-ry to consolidate and improve the achievements of previous forestry schistosomiasis control programs,and promoting the intensi-ty of technological innovation to improve the technological level of forestry schistosomiasis control programs.

Objective To analyze and evaluate neoadjuvant chemotherapy's value and significance in combining with surgical treatment for limited small cell lung cancer(LD-SCLC).Methods A total of 94 LD-SCLC patients underwent complete resections combined with chemotherapy between January 2000 and January 2011 in Shanghai Pulmonary Hospital.Among these cases,initial two cycles of neoadjuvant chemotherapies were performed for all pathologically confirmed patients (Group A),and initial operations followed by adjuvant chemotherapy were administered to patients without pathology (Group B).The survival rate was analyzed by log-rank test and Kaplan-Meier method.Multivariate analysis of the prognostic factors was performed using Cox's regression model.Results Group A included 43 cases and Group B included 51 cases.The mean age was (56.37 ± 10.18) years.According to the 6th edition of Tumor,Node,Metastasis(TNM) classification of lung cancer,54 cases were at stage Ⅰ or Ⅱ,40 cases were at stage Ⅲ.Overall 5-year survival(5-YS) was 27%.The 5-YS for patients with stage Ⅰ-Ⅱ was notably better than that of stage Ⅲ (34% vs 20%,P =0.033).For patients with stage Ⅲ,the 5-YS of Group A was significantly better than that of Group B(34% vs 12%,P =0.020),besides median overall survival for Group A and Group B were 46 and 15 months(P =0.009).Furthermore,the results of multivariate analysis showed that neoadjuvant chemotherapy,surgery and histopathology of SCLC were independent factors that strongly affected survival and prognosis.Conclusion In combined surgical treatment for LD-SCLC,neoadjuvant chemotherapy obviously improved the prognosis of patients with stage Ⅲ.Therefore,it was very important and necessary that pre-surgical neoadjuvant chemotherapy was administered to resectable stage Ⅲ LD-SCLC patients.

Objective To discuss the efficacy of photoselective vaporization of the prostate(PVP) for patients with benign prostatic hyperplasia(BPH).Methods From July 2006 to August 2007,110 patients with BPH received PVP in our hospital.The safety of the procedure,Pre- and postoperative Qmax,and IPSS of the cases were recorded and analyzed.Results The mean operation time was(51.2?36.3) minutes(ranged from 15 to 180).In the patients,23 cases had a prostate weighed ≥100 g,9 of them received TURP during the procedure.89 patients underwent bladder irrigation for 15 to 48 hours(mean,36 hours).After the operation,urinary catheter was left indwelling in all the patients except for 6(

Objective To evaluate the efficacy, safety and complications of minimally invasive percutaneous radiofrequency ablation(PRFA) therapy for hepatic cavernous hemangioma(HCH). Methods Twelve patients with total 15 HCHs (2.5cm to 9.5cm) were treated by using RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound. Tumors larger than 3cm were treated by multiple overlapping ablations that encompassed the entire lesions as well as an approximately 0.5cm rim of normal liver tissue. Results The procedures were successful and the patients recovered well without the complications of bleeding or bile leakage after mean 48-month follow up period. Spiral CT scanning showed that the contrast enhancement was disappeared within the lesions or at their periphery in all cases. The mean diameter of the ablated HCHs reduced 68%. Conclusion The results suggested that PRFA therapy was a minimally invasive, simple, safe, and effective approach for treating HCHs in selected patients.
