Objective To analyze the changing rules of schistosomiasis endemic situation before and after reaching the crite-ria of schistosomiasis transmission controlled or transmission interrupted in Zhejiang Province,so as to provide scientific evi-dence for schistosomiasis contro1. Methods Xiuzhou District and Zhuji City were selected and investigated retrospectively to collect schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. The database of retrospective investigation was established for analyzing the trends and rules of changes of Oncomelania hupensis snail status and schistosome infection status of cattle and human. Results The snail status and schistosome infection kept a steady declining before reaching the criteria of transmission controlled ,and there were positive correlations between the area of living snails and the infection rates of human and animal in two places(rhuman=0.764,P<0.01, rcatl e=0.709,P<0.01;rhuma=0.775,P<0.01,rcatl e=0.676,P<0.01);No local infection person and animal except residual snails, and found 7 cases of imported infection source were found after reaching the transmission interruption. Conclusion The epi-demic status of schistosomiasis in zhejiang is stable after reaching the criteria of transmission interruption ,and residual snail are easy to re-found and spread under some certain conditions,and some imported cases were found sometimes,which may in-crease the risks for re - emergence of schistosomiasis. The integrated solidification strategy with emphasis on control of residu-al snails and imported cases should be taken in the areas of transmission interruption in the future.

Objective To survey on the prevalence of schistosomiasis among floating population in Zhejiang province. Methods A survey on prevalence of schistosomiasis among floating population was conducted from September to November 2008, and the stratified cluster sampling method was adopted in the survey. Totally 129 villages of 19 counties or districts were selected as survey sites, and 100 samples of migrants aged 6 to 65 from schistosomiasis-endemic areas were taken in each selected village. All selected individuals were surveyed by questionnaire and underwent serum indirect hemagglutination (IHA) test. For individuals with positive serum IHA testing the fecal examination was carried out to detect the eggs by nylon sedimentation method. SPSS 13.0 software was used for data processing. Results The number of migrants in survey sites was 3 357 420, among whom 303 219 were from schistosomiasis-endemic areas (9.03%).The positive rate in serum IHA test was 2.06% (286/13 898), 276 IHA-positives individuals received fecal examination, and 7 cases were positive (2.52%). Based on above data it was estimated that there would be potentially about 33 500 serum IHA-positive cases and 845 egg-positive cases among floating population in Zhejiang province. Conclusion The risk of schistosomiasis transmission still exists in Zhejiang province due to the infected migrants from endemic areas, and a surveillance system and quick response are required for prevention of re-emergence of the disease.

OBJECTIVE To study characteristics of changing T lymphocytes in epidemic hemorrhagic fever(EHF) patients during acute phase and find out the pathogenesis,in order to elevate the level of early diagnosis.METHODS The anticoagulant blood from 30 cases of EHF patients and 50 normal healthy blood donors was collected.T lymphocyte subsets were detected by flow cytometry.RESULTS Compared with those of normal persons,CD4+ T cell counts of EHF patients decreased,CD8+T cell and double CD4+CD8+ cell(double positive cells,DP cell) counts of EHF patients increased obviously,and 25 cases of EHF in recovery stage returned to normal.And in comparison with HIV,CMV and EBV patients,DP cell counts of EHF patients increased obviously.CONCLUSIONS T lymphocytes of EHF decrease obviously but could be resumed,detection of amounts of lymphocyte subsets and CD4+CD8+ cells can provide an early diagnosis method to EHF.

The mollusicidal effect and toxicity to fish with META-Li in field were tested in mountain areas in Zhejiang Province. The snail control test, which had 3 groups including a META-Li group, niclosamide group and control group, were performed by the spraying method. The adjusted mortalities of snails in the META-Li group on the 3rd, 7th and 15th day were 89.76% , 87.98% and 94.10% , respectively, in the niclosamide group were 89.70% , 83.22% and 94.72% , respectively .and there was no significant difference between the two groups ( P > 0.05), but they were decreased obviously compared with the control group, which were 9.24% , 9.50% and 15.21% , respectively(P <0.05). The toxicity test to fish with META-Li included 3 groups, namely a high concentration META-Li group, low concentration META-Li group and control group, and none fish was dead. It is suggested META-Li has low toxicity to fish, and is suitable to snail control in aquiculture areas.

Insomnia is the second most common psychiatric disorder in clinical practice, and more than one-third of adults may experience different forms of insomnia during their lifetime, but the root causes behind insomnia need further clarification. Early evidences from twins and family studies had shown that insomnia can be attributed to genetics. In recent years, with the rapid development of gene sequencing technology, Nature Genetics had published several consecutive articles focusing on insomnia and genes, confirming that genetic factors played an important role in the occurrence and development of insomnia. Therefore, the recent research progresses on insomnia and circadian rhythm, cytokines, neurotransmitters, and other related genes were summarized in this review, which could help to understand the pathogenesis of insomnia and develop precise treatment strategies.

Objective To find out current distribution of Oncomelania snails and Schistosoma infection in snails in Zhejiang Province, so as to improve the project of schistosomiasis control. Methods Investigation spots were selected by stratified cluster sampling method, 100 villages of 34 counties were selected from 7 106 villages of 55 counties as survey spots. Synchronously systematic and environmental samplings were used for the survey. Snails were dissected to determine the infection status and spots with sham snails were set to assess the quality of the survey. Results The result showed that snails were found in 223 strips, 1 572 frames and 73 300 m 2 area in 32 villages of 21 counties. Snails were found in an area covering 72 640 m 2 in 29 villages of 18 counties in hilly region, which accounted for 99.1% of total snail habitats. The significantly larger area with snails was revealed in hilly region than that in water network region (t=3.04, P

Currently, bariatric surgery, which includes restricted intake, malabsorptive and mixed surgeries, is known to be an effective measurement for the durable treatment of obesity and related comorbidities. By changing the anatomy of gastrointestinal tract, bariatric surgery achieves the principles of restricting food intake, reducing food absorption, increasing satiety and prolonging gastric emptying to help patients lose weight and regulate metabolic mechanism. Through the neuromodulation of brain-vagus-taste receptors, sensation-specific satiety can reduce the food intake. The brain-gut-microbe axis plays a central role in maintaining homeostasis through neuronal pathways in the brain, vagus, spinal nerves, enteric nervous system and signaling pathways. Bariatric surgery can inhibit the development of hypertension, diabetes, non-alcoholic fatty liver, cardio-vascular and cerebrovascular diseases in the regulation of body fluids through adipokines, bile acids, hormones and other signaling factors. Therefore, the improvement of metabolic-related diseases after bariatric surgery is the result of the interaction of multiple factors such as nerves, body fluids, and microorganisms. The authors summarize the literature reports to introduce the mechanism of neural and humoral factor regulation in weight loss and improvement of metabolic-related diseases after bariatric surgery.
