1.An analysis of surveillance outcomes of water-borne endemic fluorosis in Yushui district and Ningdu County of Jiangxi Province in 2014
Chinese Journal of Endemiology 2016;35(12):880-882
Objectives To understand the control and prevention status of water-borne endemic fluorosis in Jiangxi Province, in order to provide a scientific basis for evaluate and perfect the strategies in control and prevention of the disease. Methods According to monitoring project of national water-borne endemic fluorosis, three villages were chosen to investigate the status and the fluoride content of fluorosis villages with water-improving and defluoridation projects in Yushui district and Ningdu county of Jiangxi Province. Investigation consisted of the status of dental fluorosis of children aged from 8 to 12 years and adult skeletal fluorosis, as well as fluoride content of drinking water and urinary fluorine. The standard detection methods of domestic drinking water was used for water fluoride content detection, fluoride selective electrode was chosen for urinary fluorine detection, Dean detection method was used to determine dental fluorosis, and diagnostic criteria of endemic skeletal fluorosis was chosen for diagnose of skeletal fluorosis. Results In fluorosis villages with water-improving and defluoridation projects which operated normally, the fluoride content of drinking water was lower than 1.00 mg/L. In fluorosis villages with water-improving and defluoridation projects which never operated normally, the average fluoride content of drinking water was 1.76 mg/L. The detection rate of dental fluorosis of children aged 8-12 years was 12.50%(22/176). A total of 294 adults were examined by X-ray, 3 adults were diagnosed as skeletal fluorosis, and the detection rate was 1.02%. A total of 294 adult urine samples were tested. The urinary fluoride content varied from 0.28 to 7.74 mg/L, and the geometric mean was 1.10 mg/L. Conclusions The illness condition of water-borne endemic fluorosis has been under control effectively. The maintenance of water-improving and defluoridation projects and surveillance were main tasks in control and prevention of the disease in the future.

Objective To compare the characteristics of remifentanil and sufentanil for tracheal intubation general anesthesia in gyneco-logical laparoscopic operation. Methods 80 patients received gynecological laparoscopic operation were randomly divided into the remifen-tanil group and the sufentanil group with 40 patients in each group, and they were performed total intravenous anesthesia with remifentanil or sufentanil respectively. Compare the changes of heart rate, mean arterial pressure in the two groups before and after induction, at the time of intubation, pneumoperitoneum, and after the operation. And differences in two groups were recorded in the recovery time, extubation time, postoperative pain in 24 hours, exhaust time and postoperative complications. Results Change trend and magnitude in heart rate, mean ar-terial pressure had no significant difference in the two groups (P>0. 05). The recovery time, extubation time in remifentanil group was shor-ter (P<0. 01), postoperative pain in 24 hours in sufentanil group was more mild (P<0. 01). Exhaust time and postoperative complications of the two groups had no significant difference (P>0. 05). Conclusion Remifentanil and sufentanil used in gynecological laparoscopic op-eration can achieve good effect. and effects of the two drugs on hemodynamics were similar. Remifentanil can recieve better effect in terms of recovery time, while sufentanil has better postoperative analgesia effect.
