RESUMO
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.

RESUMO
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.
RESUMO
OBJECTIVE: To analyze the endemic situation of schistosomiasis after its interruption of transmission in Xiuzhou District, Jiaxing City, Zhejiang Province, so as to provide the references for future surveillance work. METHODS: The data of schistosomiasis and Oncomelania hupensis snails in Xiuzhou District were collected and analyzed statistically. RESULTS: From 1994 to 2015, totally 975 village-times were investigated for O. hupensis snails, and the accumulated area of 4 385.31 hm2 was surveyed. Twenty former snail sites were reoccurring, with an area of 32.61 hm2. An area of 57.71 hm2 was supplied with snail eradication measures. Totally 11 941 snails were dissected and no schistosome infected snails were found. The serum and stool tests were performed to 221 794 and 3 731 residents respectively, and no local infection cases but four imported cases were found. CONCLUSIONS: The endemic situation of schistosomiasis in Xiuzhou District is stable after the transmission was interrupted. However, there are imported schistosomiasis cases, and therefore, the prevention of imported infection source is the focus of surveillance work.
