Objectives To analysis the prevalence and major risk factors of common chronic diseases among adult residents in the city zone of Shaoyang. To formulate and evaluate the measures of health intervention. Methods Using multistage stratified random sampling, 5267 residents aged 18 or above from 26 communities of Shaoyang were invited to participate in the survey, which was 1.24% of Shaoyang municipal residents. Questionnaire, physical examination, biochemistry test and B-ultrasonography on the liver and cholecystis were undertaken. Health intervention and evaluation was undertaken too. Results The prevalence of hypertension, fatty liver, cholelithiasis, high blood sugar, dystipidemia and overweight obesity was respectively 22.0% , 24.2%, 7.4%, 8.2%, 43.7%, 47.6%. The prevalence of hypertension, high blood sugar, dystipidemia and overweight obesity was down respectively significatively to 19.6%, 5.0%,35.6% and41.1% after intervention(P<0.05). Conclusions There is a high prevalence of common chronic diseases in the city zone of Shaoyang, which can be effectively reduced through health management programme.

Objective To investigate the value of ultrasound locates the appendectomy and guide appendec -tomy incision in small incision appendectomy .Methods According to the digital table ,80 patients with acute appen-dicitis diagnosed by B ultrasound examination , were randomly divided into the observation group , and the control group.Each of the group has 40 cases and use small incision appendectomy .In the observation group , mark corre-sponding appendix root in the abdominal wall surface when use B ultrasound examination ,and mark again in anesthe-sia before surgery.Design of a 2~2.5cm minimal incision according to appendix after anesthesia marker ,distance measurement before and after .The control group did not use B ultrasound localization ,minimal incision by McBurney point or near tenderness point .Between the two groups in operation time ,bleeding volume ,postoperative exhaust time , hospitalization time,complications.Results Ultrasound before and after positioning distance was (1.9 ±0.6)cm,and the preoperative immediate ultrasound localization of appendix and intraoperative exploration results ,and preoperative ultrasound localization in observation group ,the average operation time was better than no ultrasound localization of group(P<0.05).The amount of bleeding volume,postoperative exhaust time,hospitalization time,complications had no obvious difference .Conclusion Preoperative immediate ultrasound can more accurately reflect the position of ap-pendix ,favorable operation in small incision appendectomy is quickly ,shorten the operation time .
