This report analyzes the status of schistosomiasis epidemic,surveillance and challenges in transmission?interrupt?ed areas of Jiangxi Province. There are 24 schistosomiasis transmission interrupted counties(cities,districts)among 39 endem?ic counties(cities,districts). Among the 24 counties,there are 6 counties with Oncomelania hupensis snails and 461 villages endemic,with 1.29 million residents. Since 2009,there have not been acute and chronic cases of schistosomiasis and all the pa?tients are historical advanced schistosomiasis cases. The area with snail habitats is 37.02 hm2. Since 2015,the schistosomiasis surveillance has covered the entire transmission interrupted areas. However,there are still many challenges,such as endemic in?stability,weak surveillance capacity,lack of surveillance awareness and other issues. Towards the schistosomiasis elimination, the surveillance should be based on the snail monitoring mainly,supplemented by the mobile population monitoring,and in ad?dition,the capacity building,standardized report of endemic,and snail habitat reform should also be further strengthened.

Objective To explore the effects of patient participation-based dietary intervention on nutritional status for patients with gastrectomy.Methods Fifty-two patients with gastrectomy were randomly assigned to the intervention group(n=26) and the control group(n=26).All patients were given general dietary guidance,and patients in the intervention group were provided patient participation-based dietary intervention(PPDI) as well.Height,body weight and body mass index(BMI) were recorded at baseline,2 weeks and 12 weeks after intervention,using PatientGenerated Subjective Global Assessment(PG-SGA),Diet-Related Symptom Scale,Adherence to Dietary Scale and a 3-day food diary.Results There was no obvious change in body weight and BMI before and after 12-week intervention,while outcomes in the control group gradually decreased.For time effect,there was significant difference in PG-SGA between two groups(P＜0.05).For between-group effect,there were significant differences in diet-related symptoms(P＜0.05),dietary intake(P＜0.05) and adherence to dietary(P＜0.05) between two groups.Conclusion Patient participation-based dietary intervention can improve nutritional status for patients with gastrectomy.

Erythromycin A is a clinically important macrolide antibiotic with broad-spectrum activity. Its biosynthesis involves the formation of the 14-membered skeleton catalyzed by polyketide synthases, and the modification steps such as hydroxylation, glycosylation and methylation. Based on the understanding of the biosynthetic mechanism, it is reliable to genetically manipulate the erythromycin A-producing strain for production improvement and structure modification. In this paper, we reviewed the progress regarding erythromycin A in high-producing strain construction and chemical structure derivation, to provide insights for further development.

In order to have a better basic research of needle sticking, reports regarding basic research of needle sticking in recent years are arranged and summarized, including the concepts of needle sticking, the history origin, manipulation methods, precautions and selection requirements of needles. In the meanwhile, the reinforcing and reducing manipulation in sticking of the needle is preliminarily analyzed, and based on analysis of ancient records, three hypotheses are proposed: (1) needle sticking partly belongs to reinforcing method; (2) needle sticking partly belongs to reducing method; (3) needle sticking can perform reinforcing and reducing effects according to different manipulations. It is also believed that the needle sticking in modern clinical research is mostly used for reducing effects. However reinforcing and reducing manipulation in sticking of the needle still lacks of the support from ancient literature theory and modern clinical application, which needs to be improved.

The total efficacy rate was 81.8% in the treatment group and 60.5% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Fire needling plus moxibustion is an effective way to treat prurigo nodularis.

Objective:To observe the effect of timosaponin AⅢon the proliferation of cultured melanoma B16 and A375 cells and nitrite produced from macrophage activation. Methods:MTT assay was adopted to detect the cell growth inhibition. The morphological changes of B16 and A375 cells were observed under an inverted microscope. Nitrite production of activated mouse macrophages induced by lipopolysaccharide ( LPS) plus IFN-γ was measured by Griess assay. Results: Timosaponin AⅢ could significantly inhibit the growth of B16 cells at the concentration of 16 μmol·L-1 after the 48- and 72-hour treatment, and significantly inhibit the growth of A375 cells at the concentration ranged from 4 to 16 μmol·L-1 after the 48-and 72-hour treatment. Shrinkage, vacuoles and necrosis of B16 and A375 cells were observed after the 48-and 72-hour treatment by 16μmol·L-1 timosaponin AⅢ,the other concentration of timosaponin AⅢ showed no notable effect on B16 cells and vacuoles of A375 cells appeared at the concentration from 4 to 16 μmol· L-1. Compared with RAW 264. 7 stimulated LPS plus IFN-γ,timosaponin AⅢ could significant inhibit nitrite production of macro-phage inflammatory cell model at the concentration of 10μmol·L-1(P<0. 01). Conclusion:Timosaponin AⅢcan inhibit the prolif-eration of melanoma B16 and A375 cells and macrophage inflammation,suggesting it has anti-tumor and anti-inflammatory effects . The anti-tumor effect of timosaponin AⅢ may be related to the inhibition of tumor inflammation.
