Objective: To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents. Methods: Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents. Results: The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01). Conclusions Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

Objective:To compare the application effect of domestic and imported intravenous radiofrequency closure system in the treatment of primary varicose veins of lower extremities.Methods:This single-center prospective, non-inferiority randomized controlled trial was performed in the Department of Vascular Surgery, the Fourth Affiliated Hospital, Zhejiang University School of Medicine from January 2021 to January 2022. Patients with primary varicose veins of lower extremities who met the ataxation criteria were randomly assigned to the experimental group(domestic novel venous radiofrequency closure system) or the control group(imported venous radiofrequency closure system) in a ratio of 1∶1. The two groups of subjects were compared in terms of target vein closure rate, technical success rate, system operation performance, incidence of adverse events and incidence of serious adverse events(SAE) within 6 months after surgery. Quantitative data were compared by Mann-Whitney U test, and categorical data were compared by χ2 test and non-inferiority test. Results:A total of 80 subjects were included in the trial (41 in the experimental group and 39 in the control group), including 27 males and 53 females, aged ( M(IQR)) 55(23) years (range:40 to 78 years). There were 48 cases of left lower limb and 32 cases of right lower limb. The technical success rate and system control performance between the groups were 100%.The incidence of adverse events (58.5% (24/41) vs. 61.5% (24/39), χ2=0.075, P=0.784), and the incidence of SAE (7.3% (3/41) vs. 5.1% (2/39), χ2=0.163, P=0.686) within 6 months after surgery in experimental group and control group had no statistical significance. There was one device-related adverse event in each of the two groups. In the experimental group, one patient developed endovenous heat-induced thrombosis after surgery and recovered after taking rivaroxaban tablets. One patient in the control group had pain in the upper right thigh for more than 1 day after operation, which was cured after using analgesic cream. No device-related SAE occurred. The venous closure rate of the experimental group was 100% (38/38) at 6 months after surgery, and that of the control group was 97.4% (37/38). The difference between the two groups was 2.63% (95% CI:-3.19 to 8.45, Z=4.865, P<0.01), and the 95% CI lower limit of the difference in target venous closure rate between two groups was greater than the non-inferiority threshold of -10.00%. Conclusion:The early application effect of the new domestic intravenous radiofrequency closure system in patients with primary varicose veins of lower extremities is in line with expectations, it is not inferior to the imported system.

OBJECTIVES: Existing evidence suggests that miscarriage and stillbirth are associated with an increased risk of stroke in women. However, the impact of these events on stroke mortality remains unclear. This study aimed to elucidate the potential association between miscarriage and stillbirth and stroke mortality in women. METHODS: We employed a competing risk model using data from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial to assess the relationship between miscarriage/stillbirth and stroke death. Death from other causes was considered as a competing risk, and we conducted a subgroup analysis to explore the potential impact. RESULTS: Our study included 68,629 women for miscarriage and 65,343 women for stillbirth. No significant association was observed between miscarriage and stroke mortality (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.84 to 1.10; p=0.58). While a single stillbirth did not show a significant association (HR, 0.81; 95% CI, 0.57 to 1.15; p=0.23), recurrent stillbirth (≥2) was associated with a significantly increased risk of stroke mortality compared to women with no stillbirths (HR, 2.24; 95% CI, 1.45 to 3.46; p<0.001). CONCLUSIONS Our findings suggest that recurrent stillbirth, but not single events, is associated with an elevated risk of stroke mortality in women. Further research is warranted to clarify the underlying mechanisms and potential long-term health implications of recurrent pregnancy loss.

OBJECTIVE: To investigate effectiveness of a novel suture method-stepwise progressive ultra-tension-reducing suture method in closing high-tension wounds on the chest, back, and limbs. METHODS: A retrospective analysis was conducted on 25 patients with high-tension wounds on the chest, back, and limbs who were treated with stepwise progressive ultra-tension-reducing suture method between January 2022 and December 2022. Among the patients, there were 8 males and 17 females, with an average age of 30.5 years (range, 18-56 years). All wounds after scar or tumor resection were located on the chest, back, upper limbs, and lower limbs in 8, 6, 9, and 2 cases, respectively. The size of wounds ranged from 3.5 cm×2.8 cm to 40.0 cm×15.0 cm. All patients were advised to use topical silicone-based treatments postoperatively. The protrusion of the incision, the height of the protrusion, and the duration of the tension reduction effect were observed. The scar formation at the incision site at 6 months after operation was observed, the scar appearance was evaluated by Vancouver Scar Scale (VSS) score, and the scar width was measured. The patient's satisfaction and adverse reactions to incisions were also evaluated. RESULTS: The incisions significantly elevated, with a height of 0.3-2.5 cm, and the tension reducing effect lasted for 8.5-18.0 weeks after operation, with an average of 13.6 weeks. All incisons healed by first intention. One patient experienced transient hyperpigmentation, which resolved spontaneously. Three keloid patients showed localized redness postoperatively, and 2 experienced local recurrence, which improved significantly after treatment with triamcinolone, 5-fluorouracil injections, and laser therapy. All patients were followed up 6.0-13.5 months, with an average of 10.1 months. At 6 months after operation, all patients had linear scars, with VSS scores ranging from 1.0 to 3.5 (mean, 2.0). The width of the scars ranged from 0.5 to 3.0 mm (mean, 1.4 mm). The patients expressed satisfaction with the effectiveness. CONCLUSION The stepwise progressive ultra-tension-reducing suture method for high-tension wounds can effectively reduce the tension at the wound edges, providing a prolonged tension-reducing effect and satisfactory effectiveness.

OBJECTIVE：To provide evidence-ba sed evidence for clinical treatment and decision by evaluating efficacy ，safety and cost-effectiveness of denosumab in the treatment of giant cell tumor of bone （GCTB）. METHODS ：Retrieved from PubMed ， the Cochrane Library ，ScienceDirect，CNKI，Wanfang database and VIP as well as health technology assessment （HTA）organi- zation websites ，HTA reports ，randomized controlled trials （RCTs），single-arm trials and retrospective studies were included about denosumab in the treatment of GCTB in the adults and adolescents with mature bone ，and their qualities were evaluated. HTA reports were analyzed with descriptive analysis qualitatively ；Meta-analysis was conducted for single-arm clinical studies and retrospective studies by using R version 3.6.0 software. RESULTS ：Among 49 screened literatures ，there were 6 HTA reports ，5 single-arm trials and 3 retrospective studies ．No eligible RCTs were retrieved. HTA reports of various countries generally believed that denosumab possessed good efficacy and safety ；HTA reports of France ，Austrila and other contries showed that denosumab possessed economics. For the GCTB patients who was unresectable ，denosumab would bring the clinical benefits to about 81％ [95％CI（77％，86％）] of patients. The complete response rate and partial response rate was around 14％[95％CI（10％，19％）] and 51％[95％CI（32％，70％）]，respectively. For the GCTB patients was resectable ，denosumab would prevent some patients from receiving surgery （35％）[95％CI（21％，49％）] or bring surgical down staging to them （40％）[95％CI（36％，45％）]，the postoperative recurrence rate after experiencing the denosumab therapy was about 19％[95％CI（7％，35％）]，and median relapse time was approximately 6.73 months [ 95％CI（3.92，9.55）] after receiving surgery. Main grade 3-4 or high frequercy ADR requiring treatment was back pain ，limbs pain ，hypophosphatemia and jaw osteonecrosis. CONCLUSIONS ：Based on the currently available evidence，among the studies and regions covered in this study ，denosumab has favorable efficacy ，safety and cost-effectiveness in the treatment of TCTB.
