Objective To explore the influence of family factors on physical activity behavior of central obesity patient.Methods A questionnaire investigation to 182 central obesity volunteers was carried out in a residential district of shanghai on April 2007.Results The percentage of the patients taking physical activities,at least one of whose family members participate in regular exercise,was 66.7%.It was significantly higher than that (43.6%) of other patients whose family members hardly ever participated in regular exercise any more(χ2=9.260,P=0.002).The percentage of patients taking physical activities,with highly family function,was 60.2%.It was significantly higher than that of the patients in moderately dysfunctional family (49.9%) and in severely dysfunctional family(35.5%)(χ2=6.448,P=0.04).The average APGAR score,Partnership score and Growth score of the patients in taking exercise group were 7.13±2.63,1.49±0.71 and 1.35±0.73. They were significantly higher than that of the patients in taking no exercise group (6.09±3.09,1.24±0.85 and 0.90±0.86) (t=2.095～3.845,P=0.000～0.038). While family size,family economic status and marital status showed no obvious effect on physical activity behavior of central obesity patients(χ2=0.027～1.709,P＞0.05).Conclusion Highly family function and at least one of the other family members taking regular exercise can promote activity of central obesity patient in daily life.

This article describes the measure to decrease the emission of a domestic infusion pump which can't pass the radiated emission test when performing EMC tests. Then optimizes the measure and evaluates whether these measures affect the original electrical safety of the pump.

[Objects]To isolate and identify the pathogen of the large outbreak of dengue in Guangdong province in 2014. To understand the origin and the phylogenetic characteristics of the isolates ,and provide scientific foundation for the surveillance and prevention of dengue fever.[Methods]Collected the patient serum samples over all the Guangdong province during the 2014 outbreakperiod,isolated and identified the virus from these samples. Amplified complete E gene and complete genome with certain primers and sequenced all the products. Then the Phylogenetic ,Bayesian phylogeography and mutations analysis were carried.[Results]40 DENV-1 strains were isolated and identified. 40 complete E gene sequences and 6 complete genome sequences of DENV-1 were obtained. Phylogenetic analysis with E gene sequences revealed that the 40 isolates were classified into two genotypes including 16 genotypeⅠ(Asia)and 24 genotypeⅤ(America/Africa). 14 genotypeⅠisolates were clustered closest with isolates from Guangdong province(2013)and Sigapore(2013)which share the nucletide identities of 99.6% ~ 99.9%,other two genotypeⅠisolates were clustered with strains from Malaysia (2013) and both share the nucletide identities of 99.7%;24 genotypeⅤisolates were all classified in one clade with striains from Bangladesh(2009),China(2009)and Bhutan(2013)which share nucletide identities of 99.0%-99.9%. Further analysis with six complete genome sequences showed that five isolates were clustered closest with strains isolated from Guangdong province(2013)share the nucletide identities of 99.6%-99.8% while the sixth stains closest with strains isolated from Myanmar(2002)share the nucletide identities of 98.8%. The isolates have five amino acid mutations compared with strains epidemic in Guangdong province in 2013,three mutations(S88V,E203G,T275R)are in the EⅡdomain and one mutation (S305P)is in the EⅢdomain which associated with virulence.[Conclusions]During the outbreak in Guangdong province in 2014, DENV-1 is the predominant causative serotype,and there are at least two different kinds of genotypes of DENV-1 largely epidemiced in the whole province. Evolution analysis reveals the multiple origins of the isolates which may origin from Guangdong province , Sigapore,Malaysia,Myanmar so that we should enhance the study and surveillance of autochthonous and vectors in order to understand the epidemic way of dengue in Guangdong province. The isolates have had four mutations in the domain associated with virulence which remain further study to know their biological effects.

Objective To discuss the training effect driven by clinical demand in a cross-sectional research, and provide evidence for specialized nursing training.Methods One month before the survey, 46 nurses received various forms of comprehensive training, including multimedia lectures, workshop, case analysis, group discussion, clinical demonstration teaching of ostomy wound, research operations training, risk assessment training of pressure ulcer and incontinence associated dermatitis, etc. Then theory examinations, picture analysis examinations and operation examinations were conducted before and after training based on the unified papers and operating criteria. Results After training, the score of theoretical examination, operating examination and picture analysis examination of 46 nurses were higher than that before the training (P<0.05). 89.1% of nurses thought that the training content was very good;93.5% of nurses were satisfied with the training form, and 95. 7% of nurses thought that this training was significant for clinical work. Conclusions The comprehensive training method based on clinical demand can effectively improve the professional theory and skills of nurses, thus it can be used as a effective training and assessment methods before the survey of pressure ulcer and incontinence dermatitis in comprehensive hospitals.
