Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To evaluate the short-term efficacy of parallel overlapping anastomosis in 3D laparoscopic radical resection for transverse colon cancer.Methods:A retrospective analysis of clinical data was conducted on 73 patients who underwent 3D laparoscopic radical resection and parallel overlapping anastomosis for reconstruction of digestive tract transverse colon cancer at He'nan Provincial People's Clinical Medical School of Zhengzhou University between Apr 2019 and Jul 2023.Results:The average operation time was (165.3±28.9) min, the parallel overlapping anastomosis time was (15.6±2.6) min, the intraoperative blood loss was (47.7±19.4) ml, the first postoperative exhaust time was(2.2±0.9) d, the first time getting out of bed was (1.1±0.4) d, the number of lymph node dissection was (18.2±5.1), the first postoperative oral fluid diet time was (4.4±0.8) d, the postoperative hospital stay was (6.4±1.8) d. Anastomotic leakage occurred in one patient , who was discharged after enterostomy; Two patients with poor wound healing were cured after wound debridement and dressing change; Pulmonary infection in one patient was healed by anti-infection treatment. The postoperative complication rate was 6%, and no complications such as anastomotic bleeding, anastomotic stenosis, intestinal obstruction, abdominal infection occurred.Conclusion:Parallel overlapping anastomosis is a safe and reliable anastomotic procedure for the reconstruction of digestive tract in patients undergoing 3D laparoscopic radical resection of transverse colon cancer.

Objective To explore the surgical treatment experience of primary giant gastrointestinal stromal tumors(GIST)(with isolated lesions with a maximum diameter＞10 cm).Methods A retrospective analysis was conducted on the clinical and pathological data of 67 patients with primary giant GIST admitted from January 2018 to December 2024.Among them,35 cases underwent surgical operations after preoperative neoadjuvant therapy(25 effective cases and 10 ineffective cases)(neoadjuvant therapy group).Due to the initial diagnosis assessment expecting radical(R0)resection(13 cases),or preoperative complications(12 cases),or difficulty in obtaining a pathological diagnosis through puncture biopsy(7 cases),32 cases underwent direct surgery without neoadjuvant therapy(direct surgery group).Compare the general information,tumor condition,surgical condition,postoperative recovery,postoperative pathology,postoperative adjuvant therapy,and recurrence between two groups.Results Comparative analysis revealed that there was no statistically significant difference(P＞0.05)between the neoadjuvant therapy group and the direct surgery group in terms of gender,age,primary tumor location,initial maximum diameter,growth type,localized or locally advanced stage,and postoperative follow-up time.The maximum diameters of the tumors before surgery in the neoadjuvant therapy group and the direct surgery group were(12.4±7.1)cm and(18.2±5.0)cm respectively,and the operation times were(125.4±30.6)minutes and(153.0±31.7)minutes respectively.The intraoperative blood loss was(228.3±76.4)ml and(300.3±67.2)ml,respectively.The postoperative hospital stay was(9.1±2.6)days and(11.1±3.2)days,respectively.There was a statistically significant difference between the two groups(P＜0.05).The proportion of laparoscopic surgery in the neoadjuvant therapy group was 17.1％,which was higher than that in the direct surgery group(0),and the difference was statistically significant(P＜0.05).There was no statistically significant difference between the two groups in terms of the proportion of tumor rupture,combined organ resection,postoperative complications and postoperative recurrence(P＞0.05).Conclusion Primary giant gastrointestinal stromal tumors can mostly be reduced in size and progression through neoadjuvant therapy,improving the chances of minimally invasive surgery.However,there is also a risk of tumor progression during neoadjuvant therapy leading to increased surgical difficulty or even loss of curative surgical opportunities.

Adipocytic tumors are the most common type of soft tissue tumors,which can be divided into lipomas and liposarcomas.Studies have found that benign lipomas resected from the same site can transform into liposarcomas,especially atypical lipomatous tumors(ALT),suggesting an underlying biological association.In this case,the patient underwent resection of a right neck mass in our hospital in 2017,and the pathology showed fibrolipoma.One year later,the mass recurred at the original site but was not treated.By 2023,the mass had significantly enlarged and extended deeply.MRI showed that the lesion had an unclear boundary with the surrounding fat,suggesting liposarcoma.Puncture and molecular pathology showed MDM2 gene amplification,and the diagnosis of ALT was made,which was confirmed by pathology after complete surgical resection.It can be seen that adipocytic tumors have great differences in biological behavior,and benign lipomas can transform into liposarcomas(especially ALT).Clinically,it is necessary to combine imaging,pathology and molecular detection(such as MDM2/CDK4)for differentiation to formulate treatment plans.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.
