ABSTRACT
Objective To understand the potential risk of schistosomiasis transmission in Xiuzhou District of Jiaxing City, so as to provide the scientific evidence for consolidating schistosomiasis control achievements. Methods Fixed and mobile surveillance sites were set up in Xiuzhou District of Jiaxing City from 2013 to 2015. Oncomelania hupensis snails was surveyed historical snail habitats, current snail habitats, and suspected snail habitats. The schistosome infections were identified using serological and parasitological testing among local residents and mobile populations. In addition, the survival and reproduction of snails imported into Xiuzhou District was observed, and the schistosome infection in wild reservoir hosts was detected. Results A total of 540.14 hm2 of settings were surveyed in Xiuzhou District, Jiaxing City from 2013 to 2015, and 1.65 hm2 of snail habitats were identified. The snail habitats were mainly located in dry lands, and no infected snails or importation of snails were found. During the period from 2013 to 2015, a total of 7 668 local residents and mobile populations were examined in Xiuzhou District, and no new local infections were detected; however, three imported schistosomiasis cases were identified. Field simulation experiment showed that the imported snails laid eggs and reproduced in Xiuzhou District, and no schistosome infections were found in wild animals. Conclusion There are still residual Oncomelania snails and imported schistosomiasis patients in Xiuzhou District of Jiaxing City; therefore, the surveillance and management of local Oncomelania snails and imported schistosomiasis should be intensified to reduce the risk of schistosomiasis transmission.

ABSTRACT
Objective To learn the relationship between chronic complications of type 2 diabetic and stroke incidence.Methods Based on the surveillance data of type 2 diabetes and stroke in Xiuzhou district of Jiaxing City from 2009 to 2014, using logistic regression model method to analysis the relationships between chronic complications of type 2 diabetic and stroke incidence.Results Among 6 108 participants, 462 subjects developed stroke (7.56%);479 (7.84%) diabetes patients were diagnosed with chronic complications simultaneously and 116 subjects developed stroke (24.21%), higher than those no chronic complications (6.15%, P<0.05).The proportion of diabetic vasculopathy, nephropathy, neuropathy, retinopathy and skin infection were 33.33%, 24.64%, 23.23%, 13.48% and 5.32%, respectively.After adjusted for gender, age, occupation, urban and rural, obesity, hypertension and hyperlipidemia, there were significant statistical correlations between vasculopathy, neuropathy and stroke, the OR values and 95%CI were 4.95(3.41-7.19) and 2.79(1.80-4.32);patients who combined with any one,two, three or more chronic complications were significantly associated with the onset of stroke when compared with those without chronic complication, the OR values were 1.28, 2.75 and 5.38, respectively.Conclusion Vasculopathy and neuropathy of type 2 diabetes patients which found at diagnosed were risk factors of stroke,and the more for type 2 diabetes patients combined with the chronic complications, the greater the risk of stroke.
