Objective To understand the distribution and fluctuation tendency of infected Oncomelania snails in marshland areas of Jiangsu Province in order to provide the scientific basis for acute schistosomiasis control. Methods In each county(city, district) 5-10 marshland areas with snails were sampled randomly, and of which 5-10 sites were selected. Fifty to one hundred snails were collected in each site and dissected by professionals to determine the natural infection rate. At the same time, the mollusiciding actions were carried out in the schistosome-positive snail sites and beaches. Results In 5 years, a total of 467 beaches have been checked and 102 positive beaches were find out and the snails detected. The positive rate of beaches was 21.84%(102/467). A total of 169200 snails were dissected , and of which 433 were positive snails. The natural infection rate was 0.2559%(433/169200). The infested areas and the number of positive snails in 2002 were 2.71 and 18.33 times of those in 1998 in Jiangsu Province. Conclusion In the continuous 5 years observation, the tendency of the population of positive snails and the infested areas were significantly growing, and there is a apotential threat for the acute infections. So, the keys of the following work should be controlling snails seriously in the marshlands and the rivers in connection with the Yangtze River, increasing the mollusiciding cover rate and improving the quality in the positive beaches, and surveying and treating the cattle time by time.

AIM:To investigate the impact of excessive endoplasmic reticulum stress on apoptotic cell death in a rat model of chronic cyclosporine A ( CsA ) nephrotoxicity .METHODS: Male Sprague-Dawley rats on a low-salt diet were subcutaneously injected with vehicle (olive oil, 1 mL· kg-1· d-1) or CsA (15 mg/kg) daily for 1 or 4 weeks.Tu-bulointerstitial fibrosis and apoptotic cell death were estimated by trichrome staining and TUNEL staining .In addition , im-munohistochemistry and immunoblotting were used to evaluate the expression of immunoglobulin -binding protein ( BiP) , eu-karyotic initiation factor 2α(eIF2α), growth arrest and DNA damage-inducible protein 153 (GADD153), caspase-12 and caspase-3.RESULTS:The rats treated with CsA for 1 week did not develop tubulointerstitial fibrosis and TUNEL-positive cells, whereas 4-week treatment with CsA induced typical tubulointerstitial fibrosis and increased TUNEL-positive cells. CsA induced a significant increase in BiP and caspase-12 expression peaked at 1 week, and then returned to normal levels at 4 weeks.In contrast, the expression of eIF2α, GADD153 and caspase-3 in CsA-treated rat kidneys were significantly in-creased in a time-dependent manner .CONCLUSION:Excessive endoplasmic reticulum stress causes apoptotic cell death by depleting molecular chaperones and stimulating the proapoptotic pathway in chronic CsA nephrotoxicity .
