Objective To understand current prevalence of fluorosis, of drinking tea type in Pengyang County of Ningxia to offer scientific basis for preventing and curing, monitoring, health education. Methods Four towns were chosen as investigating spots in Pengyang County of Ningxia in 2007, from each 50 children aged 8-12 year old and 50 adults who either had tea or did not were investigated. Dean method was used to measure dental fluorosis of children and adult; meanwhile fluoride content in water, urine and drinking tea was tested using the fluoride ionic electrode method and that in brick tea using water immersion electrode method. χ2 testing, analysis of variance, u test, q test were performed. Results In adult drink tea group, control group, and children, the detaction rate of dental fluorosis were respectively 24.75%(99/400),9.5%(38/400)and 15.96%(71/445), obviously higher in drink tea group than the control group(χ2= 32.73, P<0.05). Urine average concentration of fluoride was (3.38±2.37), (2.09±1.33 ). (1.41±0.67)mg/L, obviously higher in drink tea group than the control group(u= 9.49, P<0.05). In 4 investigation spots tea fluoride averaged at (3.63±2.05)mg/L, fluoride content in drinking water was averagely (1.01±0.49) mg/L, with that of Wangwa Town [(1.31±0.33)mg/L] exceeding the national standard for drinking water (1.0 mg/L), where dental fluorosis rate was higher and fluoride content was higher than that in 3 other investigation spots (P<0.05). Conclusions Residents in Pengyang County in Ningxia who drink brick tea can cause accumulation of fluorine to poison in Ningxia, leading to fluorosis of drinking tea type; Wangwa Town have both drink tea and water fluorine poison.

AIM and METHODS: To study the changes of serum vascular endothelial growth factor (VEGF) levels in a rat model of acute myocardial infarction (MI) and its significance. Eighty-eight male Sprague-Dawley rats were used in this study. MI was produced by left coronary arterial ligation in 80 animals, and eight rats undergoing thoracotomy but not coronary ligation served as controls (sham).Blood samples were drawn from the right atrium before (sham animals) and 1, 3, 6, 12, 24 hours and 2, 3, 5, 7, 14 days after MI( n =8,respectively). Serum VEGF concentrations were measured by a sensitive enzyme-linked immunosorbent assay with a rabbit polyclonal antibody specific for VEGF. RESULTS: In 8 sham animals, the concentration of serum VEGF was (66 99?17 83) pg/mL. Six hours after MI, the level of serum VEGF significantly increased to (125 68?28 07)pg/mL ( P

Objective To evaluate the preventive effect of BCG-PSN on respiratory infection of patients with chronic obstructive pulmonary disease.Methods 48 cases with COPD were randomly divided into two groups:the BCG-PSN group and the control group.The BCG-PSN group received BCG-PSN,0 5mg,im,twice a week for 18 times injection in addition to the routine therapy,and the control group only received routine therapy.Both groups were followed up every two weeks for six months.The serum IgA,IgG,IgM levels were determined before and 4,24 weeks after the treatment.Results Cases of infection and their lasting days,infective rate in the BCG-PSN group were significantly lower than that of the control group(P

Objective To study the financial inputs into community health School of Medicine and Health Management, TONGJI Medical College of HUAZHONG[service (CHS) institutions by entities of different ownerships, by comparison of their investment, housing and human resources for policy recommendations.Methods Choose 6 cities in the East, Central and West of China through stratified random sampling. Collect data by literature review, in-depth interview, focus group discussion and questionnaire survey. Analyze quantitative data through EPI data 3.02 and SPSS 13.0.Results The institutions owned by the government and hospitals were advantageous in financial investment and housing; institutions under social organizations or individuals were inferior with development supports (P=0.00). Conclusion The community health service principle of government dominance and social involvement should be advocated, with equal opportunities for community service providers of various ownership. Emphasis should be placed on betterment of policies and measures, specific budget subsidy, as well as performance appraisal and service supervision. These measures aim at encouraging non-government providers to play greater role in community health service.

ObjectiveTo study the effect of allo-human bone marrow mesenchymal stemcells (bMSCs) on the secretion of interleukin(IL)-1, tumor necrosis factor(TNF)-α and transforming grouth factor (TGF)-β of patients with rheumatoid arthritis (RA) in vitro. MethodsBMSCs were isolated from bone marrow of healthy volunteers and purified by density gradient centrifugation and cultured in vitro. The mononuclear cells from the peripheral blood of patients with RA and healthy controls were isolated respectively.bMSCs and mononuclear cells were co-cultured in vitro and the density of IL-1, TNF-α and TGF-β3 in the co-culture system were detected by ELISA. ANOVA and Pearson correlation were used for statistical analysis.ResultsMononuclear cells from peripheral blood of patients with RA were co-cultured with bMSCs for seven days. There were an decreased density ofIL-1[(38.4±0.5) vs(6.2±1.0) ng/L], TNF-α[(29.4±1.3) vs (4.6±1.2) ng/L]and an increased density of TGF-β[(2.6±1.0) vs (22.5±2.2) ng/L]in the co-culture system (P＜0.05). But on the other hand, for healthy volunteers there were no significant change in the density of IL1[(4.4±1.1) ng/L]and TNF-α[(5.0±1.7) ng/L]in the coculture group, as compared with the mononuclear cell group[(4.4±1.3) vs(5.3±1.7) ng/L](P＞0.05). There was an increased density of TGF-β in the coculture system[(4.8±1.4) vs(10.5±1.2) ng/L](P＜0.05). IL-1 was positively correlated to TNF-αt (r=0.896,P=0.000), TNF-β1 was nagative correlation with 1L-1 and TNF-α (r=-0.356,P=0.019; r=-0.380,P=0.000).ConclusionHuman bone marrow MSCs have modulatory effects on main cytokines of patients with RA in vitro. bMSCs could down-regulate the levels of IL-1 and TNF, but up-regulate the density of TGF-β. These immune-modulatory effects are not MHC restricted. The results of this study have provided evidence for the development of effective therapy for RA.
