Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To investigate the diagnostic values of different imaging techniques in congenital esophageal atresia and tra-cheoesophageal fistula.Methods Imaging findinfs of 34 infants with congenital esophageal atresia and tracheoesophageal fistula were retrospectively analyzed.34 infants undertook X-ray and esophageal imaging,and 1 7 infants also undertook CT examination.Results Based on Gross classification,there were 2,32,9 and 23 cases for type I,Ⅲ,Ⅲa and Ⅲb,respectively.Coexistence of other de-formity was observed in 10 cases.Plain chest and abdomen X-ray film showed gastric pneumatosis in 32 cases,varied degrees of pneumonia in 25 cases and right upper pulmonary atelectasis in 3 cases.Esophagography showed a cecum in upper esophageal in 34 cases,distal tracheoesophageal fistula in one case.CT examination indicated distal tracheoesophageal fistula and orificium fistulae in 14 cases.Conclusion Combination of X-ray and CT imaging results with clinical symptoms can aid early detection and typing of con-genital esophageal atresia,furthermore provides guidance for operation and finally improves the survival rate of infants.
