Objective To investigate the progress and effectiveness of water-improving defluoridation projects comprehensively in control of fluorosis in drinking-water-borne endemic fluorosis areas in Hubei Province,and to provide a scientific basis for making strategies in prevention and control of endemic fluorosis.Methods All villages affected by fluorosis in drinking-water-borne endemic fluorosis areas were selected in Hubei Province,in which the progress and effectiveness of water-improving and defluoridation projects were investigated in 2015.Those villages were chosen to determine fluoride content of drinking water,and to check the prevalence of dental fluorosis of children 8 to 12 years old.Water fluoride content was tested with fluoride ion-selective electrode,and dental fluorosis was diagnosed by the Dean method.Results The water improvement projects were completed in 197 villages in the 30 disease affected counties (cities) with accomplishment rate 100.00％ (197/197),geometric mean of water fluorine 0.36 mg/L,qualified rate of water fluorine 100.00％ (197/197) and normal operation rate of the water-improvement projects 95.94％ (189/197).Totally 14 856 children aged 8-12 were examined their dental fluorosis.The prevalence rate was 1.78％ (265/14 856) and the dental fluorosis index was 0.04,which meant epidemic strength was negative.Totally 29 out of the 30 disease affected counties (cities) had met the disease control standards.Conclusion The prevalence of drinking-water-borne endemic fluorosis in Hubei Province has been under control,but management and monitoring of the water improvement projects still should be strengthened.

Objective To investigate the effect of minocycline on isoflurane-induced hippocampal neuroapoptosis and cognitive dysfunction in aged rats. Methods Forty-five male SD rats were randomly assigned into 3 groups ( n=15): blank control group ( group C) , 1.5% isoflurane group ( group I) and 50 mg??kg-1 minocycline+1.5% isoflurane group ( group M+I) . Minocycline was injected intraperitoneally 12 h before the start of anesthesia for group M+I.Group I and group M+I were exposed to 1.5% isoflurane for 4 h, while group C were exposed to 30% O2-70% N2.At the end of anesthesia, five rats in each group were randomized to analyse arterial blood gas. The other rats in each group were sent back to their home cage until they were fully awake.Fourteen days after anesthesia, Morris water maze was used to assess the cognitive function, and then hippocampi of rats were dissected for detection of the expression of cleaved caspase3, Bax and Bcl-2. Results No difference was found in arterial gas analysis among the 3 groups (P>0.05).Compared with group C, the rats in the group I spent more time locating the platform on the third and fourth training days and the time percentage that the rats in group I spent in the target quadrant was much less (P<0.05).However, these changes were reversed in group M+I (P<0.05).The isoflurane-induced increased level of Bax and cleaved caspase3 and decline of anti-apoptotic factor Bcl-2 were restored by minocycline pretreatment ( P<0.05) . Conclusion Minocycline could attenuate cognitive dysfunction induced by isofluranein aged rats.The mechanism is associated with inhibition of hippocampal neuroapoptosis which is increased by isoflurane.
