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.

Strategic management of tributary veins including concomitant versus staged intervention during endovenous thermal ablation for truncal varicose veins remains debated. Concomitant procedures mainly involves thermal ablation with ultrasound-guided foam sclerotherapy or phlebectomy. Staged strategies include initial truncal ablation followed by deliberated tributary management. Major venous disease guidelines exhibit substantial divergence,Japanese Society of Phlebology guidelines in 2019 contraindicate concomitant procedures, European Society for Vascular Surgery 2022 Clinical Practice Guidelines and Chinese frameworks endorse individualized decision-making,while American Vein and Lymphatic Society guidelines in 2023 prioritize concomitant procedures. Systematic literature review reveals that concomitant procedures do not uniformly translate into reduced reintervention rates or improved early Venous Clinical Severity Scores, yet consistently incur elevated complication risks and postoperative pain. Conversely, staged strategies offer superior tolerability with minimized complications. Hemodynamic principles indicate that most competent tributaries undergo partial or complete regression within 6 weeks to 6 months post-ablation and hemodynamic studies demonstrate that staged approaches preserve the drainage function of tributaries, preventing edema in their respective drainage territories and reducing tributary intervention rates. Future multicenter randomized controlled trials are imperative to delineate comparative outcomes between concomitant and staged management of truncal and tributary veins.

OBJECTIVE To investigate the inhibitory effect mechanism of Anzheng Kangliu Decoction against colorectal cancer by suppressing glycolysis through regulation of the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway.METHODS Human colorectal cancer SW620 cells were treated with Anzheng Kangliu De-coction,and cell proliferation and migration abilities were assessed.Forty-two BALB/c nude mice were randomly divided into a blank control group,model group,5-fluorouracil(5-FU)group(0.025 g·kg-1),Anzheng Kangliu Decoction low-dose group(7.67 g·kg-1),medium-dose group(15.34 g·kg-1),and high-dose group(30.68 g·kg-1).The inhibitory effect of Anzheng Kan-gliu Decoction on subcutaneous xenograft tumors was evaluated by observing body weight,tumor volume,tumor mass,HE staining,im-munohistochemical staining of Ki67 and other indicators.High-throughput transcriptome sequencing was performed to identify differen-tially expressed genes and pathways in tumor tissues between the model group and the Anzheng Kangliu Decoction medium-dose group,elucidating the potential mechanism of Anzheng Kangliu Decoction against colorectal cancer.Glucose and lactate assay kits were used to measure glucose consumption and lactate production in SW620 cells and tumor tissues after Anzheng Kangliu Decoction intervention.Western blot was employed to detect the expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,hexokinase 2(HK2),and lactate dehydrogenase A(LDHA)in SW620 cells and tumor tissues following Anzheng Kangliu Decoction treatment.RE-SULTS In vitro cell experiments demonstrated that,compared with the blank control group,Anzheng Kangliu Decoction intervention significantly inhibited the proliferation and migration of SW620 cells(P<0.01),reduced glucose consumption and lactate production(P<0.05,P<0.01),and downregulated the protein expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,HK2,and LDHA(P<0.05,P<0.01).In vivo animal experiments revealed that,compared with the model group,Anzheng Kangliu Decoction suppressed the growth of subcutaneous xenograft tumors in nude mice(P<0.01),increased tumor tissue necrosis,decreased glucose consumption and lactate production in tumor tissues(P<0.05,P<0.01),and reduced the protein expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,HK2,and LDHA(P<0.05,P<0.01).CONCLUSION Anzheng Kangliu Decoction exerts an in-hibitory effect on colorectal cancer,and its mechanism may be associated with the suppression of glycolysis through regulation of the PI3K/Akt/mTOR signaling pathway.

Objective:To investigate the efficacy and safety of endovascular therapy (EVT) for early neurological deterioration (END) in patients with minor stroke due to acute anterior circulation large vessel occlusion.Methods:Consecutive patients with mild stroke due to acute anterior circulation large vessel occlusion admitted to Mianyang Central Hospital from October 2015 to October 2023 were included retrospectively. Minor stroke was defined as a baseline National Institutes of Health Stroke Scale (NIHSS) score <6. END was defined as an increase of ≥4 in NIHSS score compared to baseline within 12 hours of onset. According to whether EVT was performed or not, they were divided into EVT group and standard medical treatment (SMT) group. At 90 days after onset, the modified Rankin Scale was used to evaluate the outcome. 0-1 was defined as excellent outcome (primary outcome measure) and 0-2 was defined as good outcome (secondary outcome measure). The safety endpoints included symptomatic intracranial hemorrhage (sICH) within 72 hours after EVT and all-cause mortality within 90 days. Multivariate logistic regression analysis was used to determine the correlation between EVT and clinical outcome. Results:A total of 164 patients with minor stroke due to acute anterior circulation large vessel occlusion were included. Eighty-four patients (51.2%) developed END, of which 52 (61.9%) underwent EVT and 32 (38.1%) received SMT; 60 patients (71.4%) had excellent outcome, and 64 (76.2%) had good outcome. There was no significant difference in demographic and baseline clinical data between the EVT group and the SMT group. The excellent outcome rate of the EVT group at 90 days after onset showed a trend higher than that of SMT group (78.8% vs. 59.4%; χ2=3.680, P=0.055), but there was no significant difference in the good outcome rate and safety endpoints between the two groups. Multivariate logistic regression analysis showed that after adjusting for confounding factors, EVT was significantly and independently associated with excellent outcome at 90 days (odds ratio 4.955, 95% confidence interval 1.331-22.284; P=0.024). Conclusion:For patients with minor stroke due to anterior circulation large vessel occlusion who experience END, EVT may improve their functional outcome without increasing the risk of sICH and mortality.

Objective To study and evaluate the incidence of patent foramen ovale（PFO） and intracardiac right-to-left shunt（RLS）in the patients with varicose veins of the lower extremities. Methods From March 2023 to August 2024, 86 consecutive patients with varicose veins of the lower extremities were admitted to Cixi People’s hospital, and 57 of them who agreed to take foam sclerotherapy were selected for PFO-RLS test. Results Of the 57 patients, a total of 23 patients were positive for PFO with an incidence of 40.4% (95% CI: 27.2%-53.5%) and a total of 22 patients were positive for RLS with an incidence of 38.6% (95% CI: 25.6%-51.6%). The incidence of PFO was higher than the reported incidence in the general population, which is 26%. There were no serious complications such as pulmonary embolism or stroke occurred in all patients after surgery. Conclusions The incidence of PFO-RLS in patients with varicose veins of the lower extremities in this study was higher than that of expected in the general population. Patients with lower extremity varicose veins should be aware of the associated neurological complications when choosing sclerotherapy.

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.
