Objective:To understand the epidemic situation of drinking-water-borne endemic fluorosis in Fujian Province, and to provide more information for control and evaluation of the disease.Methods:In 2019, all villages in the 36 drinking-water-borne endemic fluorosis areas in Fujian Province were selected, in which the situation of water improvement was investigated, fluorine content of drinking water was tested and dental fluorosis of all the children aged 8 to 12 was examined. The urinary fluoride content and skeletal fluorosis of people over 25-year old was investigated in some of those villages.Results:A total of 153 disease affected villages were investigated, in which the water improvement projects were all completed. The fluoride content in each tap water sample of the water improvement project ranged from 0.00 to 1.05 mg/L, and the qualified rate was 100.00% (153/153). The normal operation rate of the water improvement projects was 95.42% (146/153). The detection rate of dental fluorosis in children aged 8 to 12 was 2.72% (76/2 789) with a dental fluorosis index 0.07. The detection rate of children's dental fluorosis was statistically different in different age groups, so was it in areas with different coverage rate of water improvement projects ( P < 0.05). The geometric mean of urinary fluorine level in adults was 0.80 mg/L ( n = 3 765), and the detection rate of skeletal fluorosis was 2.00% (6/300). Conclusion:Although some achievements have been made in the prevention and control of drinking-water-borne endemic fluorosis in Fujian Province, it is still necessary to further consolidate and enhance the water improvement projects.

Objective To determine the rehabilitation outcome of patients with stroke caused by middle cerebral artery insult. Methods Eighty-three patients were divided into three groups: cortex insult group, basal ganglia insult group and combined group. Activities of daily living (ADL), motor function and walk were assessed by using the Barthel Index, Brunnstrom Stages and walking assessment. Comparisons of all data were carried out among the groups. Results On admission, there were significant differences among the 3 groups in terms of activities of daily living, motor function and walk. The cortex insult group had the highest scores while the combined group the lowest. A comparison among the 3 groups at discharge demonstrated the same results as those on admission. It was shown that all the groups improved significantly at discharge when compared with admission status, indicating that stroke rehabilitation was effective. Conclusion The motor deficit in the combined group was the most severe, but systematic rehabilitation could make functional improvement in the patient. The basal ganglia insult group has the biggest rehabilitation potential. The cortex insult group has the best outcome.
