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.

BACKGROUND:Restoring the stability of the spine has become the consensus of spinal surgery. The canaloplasty technology has been continuously improved, but how can we get the good clinical effect of the canaloplasty, and the price affordable, many domestic scholars have to try al kinds of the improved operation methods. OBJECTIVE:To evaluate the clinical application value of cannulated screws fixation in canaloplasty. METHODS:From February 2011 to February 2013, total y 24 patients with spinal disease treated by canaloplasty using cannulated screw were retrospectively analyzed, of which 12 cases of cervical stenosis, 2 cases of intraspinal tumor in thoracic and 10 cases of intraspinal tumor in lumbar. Al patients were fol owed up after treatment. Postoperative CT and MRI were done in al patients. Clinical symptoms and radiographic changes were observed after treatment. The Japanese Orthopaedic Association score and the spinal canal cross-sectional area measurement were conducted in the patients with cervical stenosis between the preoperation and postoperation. Visual analog scale score was evaluated in patients who have the tumor in the thoracolumbar spine between the preoperation and postoperation. RESULTS AND CONCLUSION:Al patients had no complications such as nerve or blood vessel damage. Al patients were fol owed up 12 to 24 months. Imaging evaluation showed that internal fixator was stable without the hol ow screw loss or displacement. The bone grafting in groove reached bone fusion. There was no occurrence of lamina col apse or“re-close of door”. The Japanese Orthopaedic Association score and spinal canal cross-sectional area of patients with cervical stenosis during the fol ow-up after 12 months of treatment were significantly superior to those in preoperation (P<0.01). After 12 months of treatment, Japanese Orthopaedic Association scores showed that the excel ent rate of classification assessment was 92%. During the fol ow-up after 12 months of treatment, the visual analog scale of patients with thoracolumbar tumor improved from (8.2±1.6) points before treatment to (2.3±1.3) points at the first year after discharge (P=0.004 2). These results suggest that the application of cannulated screws in the canaloplasty can not only enhance the stability of the rear pil ar, and can improve the healing rate of osteotomy, and has the characteristics of inexpensive, easy to operate, and repair effect is good.
