Abstract:
Objective To investigate the knowledge about AIDS and the ability and behavior of condom use among migrant populations in Beijing city.Methods Between May and June 2010,stratified multi-stage random cluster sampling was used to select 1 498 migrant persons aged 16-69 years from construction companies,restaurants,hotels,entertainment places,and pedlars' markets in Chaoyang district of Beijing city.Data were collected through a test for behavior of condom use and a self-designed questionnaire about demographic characteristics,AIDS-related knowledge and frequency of condom use.Results The AIDS awareness rate of the participants was 65.98%(987/1 496).Among the participants,72.03%(1 079/1 498)knew that the person who was infected with human immunodeficiency virus(HIV)could not be recognized from the appearance and 72.90%(1 092/1 498)knew that mosquito bites could not transmit HIV.The ratio of the participants having sexual intercourse was 85.65%(1 283/1 498),among whom only 191 used condom every time during sexual intercourse.Only 26.04%(390/1 498)of the participants could use condom correctly,and 39.32%(589/1 498)could properly clarify that the rolled-up ridge of the condom needed to be on the outside and holding correctly the bulb at the end of condom to make sure there was no air trapped inside.Logistic regression analyses showed that the influencing factors of condom use included age,education level,AIDS awareness,and the ability of condom use.Conclusion Migrant populations in Beijing city have a high risk to take unsafe sexual intercourse and more health interventions are needed to enhance the awareness of AIDS and the ability of condom use.

Abstract:
Objective To explore the correlation between health promotion behavior and self-efficacy among young and middle-aged rural residents in Hebei province.Methods With random stratified sampling,800 young and middle-aged rural residents in Hebei province were investigated with a health promotion lifestyle scale and self-efficacy scale.The correlation between healthy lifestyle and self-efficacy was evaluated with Pearson product-moment correlation.Results The standardized score of health promotion behavior was 54.52,among which self-actualization ranked the highest(63.48),followed by interpersonal support(61.70),nutrition(60.88),stress management(50.44),health responsibility(43.15),and exercise(40.75).The score of self-efficacy was 22.75±5.92.Pearson product-moment correlation showed that overall health promotion behavior(r=0.182,P=0.000),self-actualization(r=0.208,P=0.000),interpersonal support(r=0.174,P=0.000),nutrition(r=0.125,P=0.001),health responsibility(r=0.110,P=0.004)and stress management(r=0.106,P=0.005) were positively related to the self-efficacy.However the same tendency did not show in the exercise subscale(r=0.015,P=0.702).Conclusion The health promotion behavior among young and middle-aged rural residents in Hebei province is at a medium level,and the self-efficacy is at a low level,with a positive relationship between them suggesting much attention should be paid to the self-efficacy in order to promote health behavior in the population.

Objective To investigate the expression of microRNAs(miRNAs)in myocardial tissues of diabetic mice and to find the potential target genes controled by the miRNAs.Methods C57BL/6 mice were randomly divided into normal control and diabetes model group.The mice in diabetes model group were injected in peritoneal cavity with streptozocin(150 mg/kg).At the end of six weeks,the body weight and content of blood sugar were detected.The morphology of the heart tissue was detected using hematoxylin-eosin staining.The miRNA expressions in myocardial tissue of the mice were determined by using reverse transcription miRNA PCR array.The targets of the altered miRNAs were predicted using the database(Target Scan,miRarnada and PicTar). Then the target genes(Anp,Myh7,Hadc1,Col1a1,Ccnd1,and Vcam1)related to cardiac hypertrophy or myocardial fibrosis were analyzed with quantitative real-time PCR(qRT-PCR).Results Histological analysis of heart tissues exhibited cardiac hypertrophy and extensive interstitial fibrosis and the heart weight/body weight(HW/BW)ratio was significantly higher in diabetic group. Up-regulated miR-19a,miR-19b,miR-22,and miR-503 and down-regulated miR-1,miR-29a,miR-30a,miR-96,miR-101a,miR-142-3p,miR-199-5p,and miR-374 miRNAs were identified in diabetic mice with cardiomyopathy. Target genes were approved with bioinformatics analysis. Among the targets,the mRNA expressions of Anp,Myh7 and Ccnd1 were increased,while Hadc1,COL1A1 and Vcam1 were decreased in diabetic mice with cardiomyopathy.Conclusion The results demonstrate that miRNAs play an important role in the process of diabetic cardiomyopathy,which may mediate cardiac hypertrophy and/or myocardial fibrosis in diabetic cardiomyopathy.

Abstract:
Objective To investigate iodine nutritional status and characteristics among adults,school-age children and pregnant women in iodine-sufficient areas in China since the implementation of Universal Salt Iodization(USI) in 1996.Methods A cross-sectional study was conducted.Fasting urinary iodine among 348 adults and 150 school-age children from Haixing county,Hebei province and 174 pregnant women from Tianjin were measured with As3+-Ce4+ catalytic spectrophotometry.Urinary iodine content and distribution trend of urinary iodine among the adults,children and pregnant women were determined and described.Results The median urinary iodine for the adults,school-age children and pregnant women in iodine-sufficient area were 185.20 μg/L,123.13 μg/L,and 217.06 μg/L,all at the level of adequate iodine intake.Most of the adults(62.07%),school-age children(68.67%),and pregnant women(63.22%) were in the status of iodine sufficiency,while some of the adults(12.93%),school-age children(22.00%),and pregnant women(27.59%) were in the status of iodine deficiency.There were statistically significant differences in the urinary iodine level between 3 different groups of the participants(χ2=33.738,P<0.05).Conclusion The results demonstrate that current iodine nutritional status is basically adequate in 3 groups of people in iodine-sufficient area.However,the prevalence of iodine deficiency in school-age children and pregnant women suggests the risk of iodine deficiency in iodine-sufficient area.Scientific supplementation of iodine and routine investigations on iodine nutrition should be conducted to assure adequate iodine intakes for different groups of people.

Abstract:
Objective To explore the mechanism of protective effect of vitamin D on cardiovascular tissue in the rats with myocardial infarction.Methods With a pre-experiment,the best time of 1,25 dihydroxyvitamin D3(1,25[OH]2D3) intervention was determined by observing the expressions of Toll like receptor(TLR4) and its related signaling molecules in A7R5 cells treated with both lipopolysaccharide(LPS) and 1×10-7 mol/L 1,25(OH)2D3.The rats were randomly divided into 2 groups:myocardial infarction(MI) model group(n=16) and 1,25(OH)2D3 treatment group(n=16),and a sham-operation group was used as control.The rats in 1,25(OH)2D3 treatment group were administered with 1×10-7 mol/L 1,25(OH)2D3 by gavage 48 hours after the MI operation and the rats in other two groups were treated with normal saline;the treatments were performed once a day for 4 weeks.At the end of the treatments,myocardial infarct size(MIS) and cardiac serum enzymes of the rats were detected.The level of TLR4,myeloid differentiation factor 88(MyD88),and nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB) were detected with real-time PCR and Western blot.Results Vitamin D had inhibitive effect on LPS-induced elevations of TLR4,MyD88 and NF-κB in A7R5 cells(P<0.01).Vitamin D could decrease MIS significantly(P<0.01) and improve the cardiac serum enzymes(P<0.01).Vitamin D could inhibit the expressions of TLR4,MyD88 and NF-κB in myocardial tissue(P<0.01).Conclusion Vitamin D has cardiovascular protective effect through downregulating TLR4 and its relation signaling molecules MyD88 and NF-κB.
