ABSTRACT
Objective:To investigate the effects of 3 treatment methods on serum cytokines in Kaschin-Beck disease (KBD) patients.Methods:In May 2015, according to "Diagnosis of Kaschin-Beck disease" (WS/T 207-2010), KBD patients with grade Ⅰ and above who lived in KBD areas of Guide, Xinghai and Banma counties of Qinghai Province for at least 25 years and aged 25 - 62 years old were selected as research subjects. Patients were divided into 3 groups according to different treatment methods. The first group ( n = 91) was treated with Celecoxib + Xiaohuoluo pill (concentrated pill), the second group ( n = 89) was treated with Celecoxib + bone-strengthening joint pill, and the third group ( n = 94) was treated with Celecoxib + anti-osteogenic tablet, and the overall treatment effects of 6 months after treatment of the 3 groups were compared and analyzed. The contents of serum nitric oxide (NO), tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and hyaluronic acid (HA) in patients before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA). Results:A total of 274 KBD patients were included, aged (47.24 ± 18.97) years old, including 132 males and 142 females. The treatment effective rates in the first, second and third groups were 80.22% (73/91), 77.53% (69/89) and 77.66% (73/94), respectively, and there was no significant difference between the three groups (χ 2 = 0.25, P > 0.05). Before and after the treatment, the serum NO contents of the 3 groups [(149.23 ± 20.61), (135.88 ± 29.63), (151.33 ± 22.15), (137.55 ± 31.51), (148.58 ± 24.36), (134.81 ± 28.53) μmol/L] were significantly different ( t = 2.678, 2.403, 3.195, P < 0.05), and there were no significant differences in TNF-α, IL-1β, and HA contents ( P > 0.05). Conclusion:Three treatment methods for treating KBD have achieved certain effects, all the 3 treatment methods have reduced serum NO content and have no significant effect on TNF-α, IL-1β and HA contents.
ABSTRACT
Objective To understand the epidemic situation of tea-drinking-borne fluorosis among children in Haixi Prefecture of Qinghai Province,and to provide basis for taking pertinent prevention and control measures.Methods In 2017,three townships (towns) were selected from five counties (cities) in Golmud,Delingha,Dulan,Ulan and Tianjun,Haixi,and one village (villages excluding excessive water fluoride) was selected from each township (town) as the investigation site.Fluoride content in drinking water,tea fluoride content and dental fluorosis in children aged 8-12 years were investigated.Water fluoride was determined using "Standard Test Method for Drinking Water" (GB/T 5750.5-2006);brick tea fluoride content was detected using "The Fluoride Content in Brick Tea" (GB 19965-2005);children's dental fluorosis was diagnosed using "Diagnosis of Dental Standard for Fluorosis"(WS/T 208-2011).Results Totally 75 drinking water samples were collected from each county (city).The water fluoride content ranged from 0.35 to 0.41 mg/L,with an average value of 0.37 mg/L,which was lower than the national drinking water fluoride standard of 1.00 mg/L.The fluoride content of 150 brick tea samples ranged from 206.0 to 796.0 mg/kg,with an average value of 629.8 mg/kg.A total of 1 325 children aged 8-12 were examined.The detection rate of dental fluorosis was 13.43％ (178/1 325),the index of dental fluorosis was 0.27,and the overall epidemic intensity was negative.The epidemic intensity in Dulan and Tianjun counties was marginal.There were significant differences in the detection rate of dental fluorosis among children of different ages (x2=35.26,P ＜ 0.05),and dental fluorosis was increased with ages in children.The detection rate of dental fluorosis in boys and girls was 13.31％ (90/676) and 13.56％ (88/649),respectively,with no significant difference (x2 =0.02,P ＞ 0.05).Conclusions There is an epidemic of tea-drinking-borne fluorosis among children in 5 counties (cities) of Haixi Prefecture.Although the epidemic is mild,it should not be ignored.Health education and publicity work for tea-drinking-borne fluorosis should be strengthened.
