1.Status and challenges for schistosomiasis in transmission-interrupted areas in Jiangxi Province
Chinese Journal of Schistosomiasis Control 2016;28(4):456-460
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.
2.Etiological Investigation and Analysis on Hearing Loss of Chinese People over 60 Years Old
Chinese Journal of Rehabilitation Theory and Practice 2016;22(2):218-220
Objective To investigate the causes of hearing loss for people over 60 years old. Methods People more than 60 years old in 14 provinces, 22 districts were investigated with a self-designed questionnaire, and a hearing test was also done for every subject. Results Among all the subjects, the etiological factors of hearing loss were otitis media (10.5%), hereditary deafness (2.9%), noise-induced hearing loss (3%), ototoxic deafness (6.4%), traumatic deafness (2%), presbycusis (33.8%), sudden deafness (1%) and other reasons (36.2%), respec-tively, with 11.3%unknown. Conclusion Presbycusis is the main reason of hearing loss for old people, and otitis media is the second. The cause of hearing loss is different with ages, districts, and whether in rural areas.

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.

Objective To understand the characteristic of value orientation during occupational choice and occupational development of nursing students with different background. Methods The study was non-experimental and descriptive with questionnaires. Results The correlation coefficients on 15 work value scales in different background students ranged from 0.561 to 0.940, P value ranged from 0.01 to 0.05. And the coefficients were significant. But there were significant differences on some scales in 15 work value of students who were different in grade, sex, family or areas and so on. Conclusions Nursing stu-dents with different background place emphasis on the same work value and ignore the same others because of the same social-cultural background. But there are some differences in recognition degree of some work val-ue in nursing students with different background.

Objective To investigate the effects of ginsenosides Rg 3 on vasculogenic mimicry of pancreatic cancer xenograft through the establishment of pancreatic cancer cell line SW -1990 subcutaneous xenograft model .Methods After pancreatic cancer xenograft in nude mice model beening established , All the mice were randomly divided into 4 groups and treated intraperitoneally ( IP) with saline and various concentrations (5,10,20 mg/kg) of ginsenosides Rg3.To observe the effect of ginsenoside Rg3 on tumor growth.Immunohisto-chemical-PAS staining was used to detect the effects of ginsenosides Rg 3 on vasculogenic mimicry of pancreatic cancer xenograft .and mRNA and protein expression of MMP 2、MMP9 were respectively evaluated by FQ -PCR and Western blot .Results The ginsenosides Rg3 can inhibit the growth of the tumor xenografts in nude mice .The inhibitory effect is the most obvious the 20 mg/kg of ginsenosides Rg3 group.The expression of MMP-2, MMP-9 were down-regulated compare with the control group , and the difference was signifi-cant;the Immunohistochemical -PAS staining showed the number of vasculogenic mimicry (+) and CD31 (+) were less than that in the control group .Conlusion Our results demonstrate that pancreatic vascular mimicry formation can be suppressed by Ginsenoside Rg 3 though reducing the expression of MMP -2, MMP-9 in our vivo experiments ,

Objective To investigate the clinical efficacy of fire needling plus moxibustion in treating prurigo nodularis. Methods Ninety patients with prurigo nodularis were randomly allocated to treatment and control groups, 45 cases. The treatment group received fire needling plus moxibustion and the control group, external application of halometasone ointment. Skin lesions and pruritus were scored in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the skin lesion score and the pruritus score in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the skin lesion score and the pruritus score between the treatment and control groups (P<0.01). 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.
