ABSTRACT
Objective To explore the prevalence state of drinking brick-tea type fluorosis in children in Guoluo Prefecture,Qinghai Province.Methods According to the historical prevalence of drinking tea-type fluorosis in Guoluo Prefecture,in 2017,in 5 counties of Guoluo Prefecture,according to the pastoral area,agricultural area,semi-agricultural and semi-pastoral areas,each township (town) was selected,in each township (town) drawed a natural village in a ward as a survey point.At each survey site,drinking water samples of local residents were collected,and 10 households were selected,tea samples were collected,and dental fluorosis was investigated for children aged 8-12 years old.The mean of fluoride was determined by fluoride ion selective electrode method (GB/T 5750.5-2006,GB 19965-2005),and the dental fluorosis was diagnosed based on "Diagnosis of Dental Fluorosis" (WS/T 208-2011).Results The mean of fluoride in 85 water samples was 0.34 mg/L (0.20-0.77 mg/L),the mean of fluoride in 161 brick-tea samples was 579 mg/kg (110-1 278 mg/kg).The mean of daily fluoride intake of each person was 6.78 mg,among them,73.29％ (118/161) drank brick-tea,the detection rate of dental fluorosis of 2 083 children was 22.85％ (476/2 083),and the index of dental fluorosis was 0.42,the prevalence was weak.Conclusion The prevalence of drinking brick-tea type fluorosis of children in Guoluo Prefecture is less serious.
ABSTRACT
Objective To determine the effect of community family visit on patients with metabolic syndrome.Methods According to the diagnostic criteria set up by the Diabetes Society of the Chinese Medical Association 220 patients with metabolic syndrome were equally divided into two groups:family visit group and control group.The family visit group was followed up by full-time medical staff regularly,while not interfering with the control group.After one year before and after the intervention,the relevant indicators were compared between the two groups.Results The levels of SBP,DBP,TG,TC,LDL-ch,24-hour urine protein were lowered markedly by intervention (P＜0.05).HDL-ch increased compared to the previous (t= 7.921,P＜0.05),but body mass index were not significantly changed.Before and after the intervention the levels of SBP,DBP,TG were ideal This was followed by significant improvement of fasting plasma glucose (FPG),two hours after meal blood glucose (2 hPG),TC,HDL set standards,24-hour urine protein body mass index.Compared with the control group,the family visit group showed siguificant improvement of related indicators except body mass index and TC.Condusion Intervention by family visit is effective in improving the vales of metabolic syndrome.
