OBJECTIVES:
To investigate caries status and its impact factors in preschool children in plateau and to provide reference for caries prevention in highlands.
METHODS:
Examination of caries was performed on 1 597 children aged 3-5 years old in 11 kindergartens in Changdu, Xizang, in accordance with the 4th National Oral Health Survey standards and methods. Their parents were surveyed with the questionnaire regarding oral hygiene habit and consciousness about oral health and related factors. All the data were collected and analyzed.
RESULTS:
The prevalence of caries among children aged 3-5 years old in Changdu was 52.85%, with dmft index of 2.44. The caries rate and dmft of children aged 3 years old were lower than those of children aged 4 and 5 years old (
CONCLUSIONS
The prevalence of ca-ries in children aged 3-5 years old in Changdu increases with aging. Good oral hygiene and eating habits and regular oral examination can reduce the rate of caries.

Two hundred and thirty nine patients with type 2 diabetes mellitus (T2DM) managed in the community health service centers of Huai'an city were selected for survey by random sampling method between January and December 2017.A self-designed questionnaire was used to assess self-management prescription.Patients received community management for 3 months.The rates of patients with not receiving diabetes health education,with healthy diet,with regular exercise,without monitoring blood glucose,with repeated hypoglycemic attacks were 44.8% (107/239),23.0% (55/239),46.4% (111/239),54.8% (131/239)and 21.3%(23/108),respectively;and 51.9% (124/239) of the participants did not adhere to medication.The awareness rate of diabetic complications was 27.2 % (65/239).Only 25.1% (60/239) and 15.1% (36/239) of the participants apply oral hypoglycemic agents and insulin rationally.The survey results indicate that the current status of self-management in community diabetic patients is relatively poor,it is necessary to strengthen standardized management of diabetic patients in community health institutions.

Objective:
To evaluate the safety and efficacy of dental floss traction-assisted endoscopic submucosal dissection (DFS-ESD) for rectal neuroendocrine neoplasm (NEN).
Methods:
A retrospective cohort study was performed. Clinical data of rectal NEN patients undergoing ESD at Endoscopy Center of Zhongshan Hospital, Fudan University from January 2016 to December 2017 were retrospectively analyzed. Inclusion criteria: 1) age of 18 to 80 years old; 2) maximal diameter of lesions <1.5 cm; 3) tumor locating in the submucosa without invasion into the muscularis propria; 4) no enlarged lymph nodes around bowel and in abdominal cavity; 5) ESD requested actively by patients. A total of 37 patients were enrolled, including 23 male and 14 female cases with mean age of (56.0±11.3) years. All the lesions were single tumor of stage T1, and the mean size was 0.8±0.2(0.5-1.2) cm. Postoperative pathology revealed all samples as neuroendocrine tumors (NET). Seventeen patients received DFS-ESD treatment (DFS-ESD group) and 20 patient received conventional ESD treatment (conventional ESD group). In DFS-ESD group, after the mucosa was partly incised along the marker dots, the endoscopy was extracted, and the dental floss was tied to one arm of the metallic clip. When the endoscope was reinserted, the hemoclip was attached onto the incised mucosa; another hemoclip was attached onto normal mucosa opposite to the lesion in the same way. The submucosa was clearly exposed with the traction of dental floss and the resection could proceed. The conventional ESD group received the traditional ESD operation procedure. The operation time, modified operation time (remaining time after excluding the assembly time of dental floss traction in DFS-ESD group), en bloc resection rate, R0 resection rate, morbidity of operative complication, recurrence and metastasis were compared between two groups.
Results:
The average tumor size was (0.8±0.2) cm in DFS-ESD group and (0.7±0.2) cm in conventional ESD group (
