The paper reviewed the project management model and its evolution in the national schistosomiasis control in China at different stages.The key factors impacting the progress of the control activities were analyzed by introducing the concept of project management,and the principles,i.e.objective management,temporal management,cost-effectiveness management,and quality management,that would have to be complied with in the future control activities were put forward,so as to accelerate the elimination of schistosomiasis in China.

Objective To evaluate the diagnostic value of endoscopic ultrasonography(EUS) in the eminence lesions of gastrointestinal tract.Methods The clinical data of 420 patients with gastrointestinal eminence lesions subsequently received EUS were analyzed.Results In 420 cases,235 cases lesions were located in the stomach,129 cases in the esophagus,29 cases in the duodenum and 27 cases in the colon.Occurred in the wall itself of the digestive tract lesions was 85.00％ (357/420),and 73.10 ％(307/420) of submucosal neoplasm,and gastrointestinal stromal tumor,leiomyoma or leiomyosarcoma was seen [60.24％ (253/420)].Lesions was not found in the digestive tract wall external oppression and lesions accounted for 14.52％(61/420),external lesions and infiltrated digestive tract was 0.48％(2/420).Conclusions EUS is an ideal diagnostic modality in distinguishing different layers of the wall of the gastrointestinal tract,and thus of important value in precise localization of lesions beneath the mucosa.And be able to hint the nature of the lesion.Meanwhile,this may be associated with colonic mucous membrane structure.

Objective To evaluate the reliability and validity of SF-36 in patients with advanced schistosomiasis,so as to proride scientific basis for the selection of suitable tools for health measure.Methods A Chinese version of SF-36 scale was applied to evaluate the health of patients with advanced schistosomiasis by a household survey in Hanshou County of Hunan Province and Jiangling County of Hubei Province,then the reliability and validity of the scale were tested.Results Atotal of 326 patients were investigated in the two counties.The split-half reliability(with a split-half coefficient of 0.95) and the internal consistency (Cronbach'α coefficients of the eight dimensions ranged from 0.86 to 0.88)were satisfying;the convergent and discriminative validity were high with the test successful rates of 97.14%and 87.86%,respectively;the criterion validity was acceptable with a correlation coefficient between the total score of SF-36 and EQ-5D+C VAS score of 0.70.However,the construct validity seemed to be not so reasonable as only 2 dimensions out of 8 were completely in accordance with the theoretical model on factor loading.The percentages of floor effect and ceiling effect in most dimensions were not significant except RP and RE(with the percentages of floor effect of 50.31%and 48.16%,respectively).Conclusions SF-36 is appropriate to be used in patients with advanced schistosomiasis.but some items need to be improved according to the local settings of endemic areas.
