Objective: To explore the association of health literacy with overweight and obesity among middle school students in Chongqing, so as to provide evidence for obesity prevention and control strategies. Methods: From November to December 2019, a stratified cluster sampling method was used to select 7 851 middle school students from 8 complete middle schools across 4 districts/counties in Chongqing. Participants completed the Adolescent Health Literacy Questionnaire and underwent nutritional status assessments. Chisquare tests and multivariate Logistic regression analyses were performed to evaluate associations. Results: The prevalence of overweight and obesity among adolescents was 12.95%. The overall health literacy rate and rates for functional, interactive, and critical health literacy dimensions were 62.01%, 66.02%, 50.07%, and 72.42%, respectively. Significant differences in overweight and obesity prevalence were observed across districts/counties, urban/rural areas, sex, school stages, and onlychild status (χ2=25.93, 3.86, 80.55, 8.80, 6.43, P<0.05). After adjusting for confounding factors, multivariate Logistic regression revealed that middle school students with overall health literacy (OR=0.86, 95%CI=0.75-0.99), interactive health literacy (OR=0.85, 95%CI=0.74-0.97), and critical health literacy (OR=0.84, 95%CI=0.73-0.98) had a lower risk of overweight and obesity (P<0.05). Conclusions Health literacy is inversely associated with overweight and obesity among middle school students. Strengthening health education and improving interactive and critical health literacy may create favorable conditions for adolescent overweight and obesity prevention and control.

Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Objective To investigate the clinical value of tumor-stroma ratio (TSR) in combination with KRAS, BRAF, NRAS, and microsatellite status for prognostic assessment of patients with colorectal cancer. Methods A total of 51 colorectal cancer cases meeting the inclusion and exclusion criteria were enrolled in this study. TSR levels were evaluated through optical microscopy. The KRAS/NRAS/BRAF mutation profiles and microsatellite status were determined in accordance with genetic testing results. Clinical data, pathological characteristics, and survival outcomes were systematically recorded. Results Among the 51 patients with colorectal cancer, 19 (37.3%) were categorized into the low stromal group and 32 (62.7%) into the high stromal group. Statistically significant differences were observed between the two groups in drug resistance, M stage, TNM stage, neural invasion, and microsatellite status (P<0.05). Compared with patients exhibiting high TSR, those with low TSR demonstrated significantly increased recurrence rates (5 vs. 21 cases, P=0.007), shortened disease-free survival (34.21 vs. 14.34 months, P=0.001), and reduced overall survival (38.79 vs. 23.09 months, P=0.021). Multivariate Cox regression analysis identified N stage, M stage, TNM stage, neural invasion, lymphovascular invasion, and TSR as independent risk factors for disease-free survival. N stage, M stage, neural invasion, lymphovascular invasion, and TSR emerged as independent prognostic factors for overall survival (P<0.05). Although the combined models of TSR with KRAS, NRAS, BRAF, and microsatellite status, respectively, demonstrated overall statistical significance (P<0.05), none of the dummy variables in these models reached individually statistical significance (P>0.05), and therefore cannot be considered independent prognostic factors. Conclusion TSR serves as an independent predictor of poor prognosis in advanced colorectal cancer, with patients exhibiting low TSR demonstrating a significantly higher risk of recurrence and metastasis than those with high TSR. For patients with colon cancer undergoing first-line palliative chemotherapy after postoperative recurrence, histopathological assessment of TSR in primary tumor sites holds prognostic value and may serve as a relevant factor for evaluating treatment resistance in clinical management.

Objective: To explore the independent effects and gender differences of different types of adverse childhood experiences (ACEs) on the co-occurrence of non-suicidal self-injury (NSSI) and suicide attempts (SA), so as to provide a reference for the precise prevention and control of self-harm in junior high school students. Methods: From May to June 2023, a total of 7 360 junior high school students were selected from 12 schools in three districts/counties of Chongqing using a combination of stratified cluster sampling and convenience sampling methods. Information on NSSI, SA, ACEs, and depressive symptom, as well as other related data were collected through the Adolescent Non-suicidal Self-injury Assessment Questionnaire (ANSAQ), suicide related section of the Chinese Adolescent Health related Behavior Questionnaire (Junior High School Version), Childhood Trauma Questionnaire-Short Form ( CTQ- SF), and Center for Epidemiologic Studies-Depression Scale (CES-D). Statistical analyses of the data were performed using the Chi-square test and multiple Logistic regression. Results: The detection rates of NSSI, SA, NSSI+SA and ACEs in junior high school students were 19.2%, 4.6%, 3.5% and 57.9% respectively. After controlling for factors such as gender, grade, family type, self rated family economic status, self rated academic performance, self rated academic pressure, number of close friends, and depressive symptom scores, results from the multiple Logistic regression analysis showed that junior high school students with physical abuse ( OR = 1.98, 95% CI =1.23-3.18), emotional abuse ( OR =2.83, 95% CI =1.92-4.19), sexual abuse ( OR = 1.70, 95% CI =1.07- 2.69 ), physical neglect ( OR =1.67, 95% CI =1.20-2.33) and witnessing domestic violence ( OR =2.10, 95% CI =1.41-2.87) in childhood had higher risks for the occurrence of NSSI+SA (all P <0.05). After stratification by gender, boys with sexual abuse in childhood had a high risk for the occurrence of NSSI+SA ( OR =2.17, 95% CI =1.06-4.43), whereas girls with emotional abuse ( OR =3.69, 95% CI =2.29-5.94), physical neglect ( OR =1.62, 95% CI =1.07-2.45) and witnessing domestic violence ( OR =2.17, 95% CI =1.41-3.34) in childhood had hgih risks for the occurrence of NSSI+SA (all P <0.05). Conclusions Different types of ACEs have different effects on the co-occurrence of self-harm in junior high school students and there are gender differences. When family interventions are conducted for the combined model, emphasis should be placed on aspects of emotional abuse and domestic violence while optimizing the interventions based on gender differences.

Aim To investigate the mechanism of curcumin inhibition of oxidative stress on osteogenic differentiation and its dose-dependent anti-osteoporosis effect.

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC₅₀ values of 3.77 μmol·L^-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

BACKGROUND:Acromion morphology is the most important external factor of degenerative rotator cuff tear,and studies on acromion morphology and acromion coverage have been continuing. OBJECTIVE:To investigate the coverage of acromion on rotator cuff tissue in three-dimensional space,measure coronal and sagittal parameters,and explore the relationship of acromial overhang,acromioglenoid angle and acromial coverage angle with degenerative full-thickness rotator cuff tears. METHODS:A total of 56 patients diagnosed with full-thickness rotator cuff tears by shoulder arthroscopic surgery or MRI in the Affiliated Hospital of Xuzhou Medical University from January 2022 to June 2023 were retrospectively collected as the tear group,while 48 patients with non-rotator cuff tear were included as the control group.Clinical data and chest CT data of the patients of the two groups were collected,and the shoulder blades of the patients were reconstructed using Mimics software.Acromial overhang,acromioglenoid angle and acromial coverage angle were measured in 3-matic software.The differences between the measurement parameters were compared between the two groups.Binary Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the ability of the measurement parameters to predict rotator cuff tear.It is generally believed that the parameter had good diagnostic value when the area under the receiver operating characteristic curve was greater than 0.8. RESULTS AND CONCLUSION:(1)The mean acromial overhang in patients with rotator cuff tears was greater than that in controls(P<0.001).The mean acromial coverage angle was also greater in patients with rotator cuff tears than in controls(P<0.001).There was no significant difference in the acromioglenoid angle between the two groups(P>0.05).(2)Binary Logistic regression analysis showed that acromial overhang and acromial coverage angle were both risk factors for rotator cuff tear(P<0.05).(3)Receiver operating characteristic curve analysis indicated that the areas under the curve of acromial overhang and acromial coverage angle were 0.725 and 0.865,respectively,and the optimal cutoff values were 36.15 mm and 60.65°.(4)The results showed that the acromial overhang and acromial coverage angle were greater in patients with rotator cuff tears than in patients without rotator cuff tears.Both were associated with degenerative full-thickness rotator cuff tears,and they could be used to predict rotator cuff tears,and the acromial coverage angle was more effective in predicting rotator cuff tears.

Objective:To investigate the safety and short-term efficacy of laparoscopic Nissen fundoplication in the treatment of refractory gastroesophageal reflux disease (rGERD).Methods:The clinical data of 61 patients underwent laparoscopic Nissen fundoplication from March 2018 to March 2022 in Jiangyin People′s Hospital were retrospectively analyzed. Among them, 14 patients had significant symptom relief after using proton pump inhibitor (PPI) before operation (group A), 30 patients had partial symptom relief after using PPI (group B), and 17 patients had persistent symptoms despite regular treatment with double-dose PPI for more than 8 weeks (group C). The surgical outcomes and recovery were compared among the three groups.Results:For the 61 patients, the surgical time was (117.46 ± 28.50) min, the intraoperative blood loss was 23.00 (8.00, 34.00) ml, and the postoperative hospital stay was 3.00 (2.00, 5.00) d. There were no statistically significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, concurrent hiatal hernia repair and mesh placement among the three groups ( P>0.05). No short-term severe complications such as abdominal bleeding, abdominal infection and gastrointestinal perforation occurred in any group. There were no statistical differences in satisfaction score, subjective relief of overall postoperative symptoms, reflux symptoms, PPI usage, dysphagia, abdominal distention, diarrhea or constipation among the three groups ( P<0.05). No upper abdominal pain, recurrence and reoperation occurred in the three groups. Conclusions:Laparoscopic Nissen fundoplication has a definite therapeutic effect on rGERD, with significant anti reflux effects. There are no serious complications after surgery, and there are no recurrence or reoperation.

Anhedonia is defined as the reduction of pleasure and reward-seeking behavior,and it is prevalent in approximately two-thirds of individuals diagnosed with post-traumatic stress disorder(PTSD).Numerous empirical studies have consistently demonstrated that anhedonia represents an independent symptom dimension of PTSD.Furthermore,additional investigations have revealed that anhedonia plays a crucial role in the psychopathology of PTSD,contributing to the maintenance of post-traumatic stress responses,as well as more severe functional impairment and reduced therapeutic responsiveness.This paper aims to discuss the definition,psychopathology,genetic mechanisms and neurobiological underpinnings of anhedonia in PTSD,thus providing insights for future research on anhedonic symptoms.

Objective:To explore the clinical characteristics, diagnosis, treatment, and follow-up of multisystem inflammatory syndrome in children (MIS-C) related to SARS-CoV-2 Omicron variant infection.Methods:A retrospective analysis was conducted on clinical data of 11 children with MIS-C, who were admitted to the Department of Pediatrics of Peking University First Hospital from December 2022 to January 2023. Clinical characteristics, treatment, and follow-up of MIS-C were summarized in this study.Results:The 11 cases contained 7 boys and 4 girls, with an age of 4.4 (2.0, 5.5) years on admission. All the patients had fever, with a duration of 7(5, 9) days. Other clinical manifestations included rash in 7 cases, conjunctival hyperemia in 5 cases, red lips and raspberry tongue in 3 cases, lymphadenopathy in 3 cases, and swollen fingers and toes in 2 cases. There were 8 cases of digestive symptoms, 8 cases of respiratory symptoms, and 3 cases of nervous system symptoms. Eight patients had multi-system injuries, and one of them had shock presentation. All 11 patients were infected with SARS-CoV-2 Omicron BF.7 variant. The laboratory examination results showed that all cases had elevated inflammatory indicators, abnormal coagulation function and myocardial damage. Six patients had elevated white blood cell counts, 5 cases had liver function abnormalities, 3 cases had kidney function abnormalities, and 8 cases had coronary artery involvement. All 11 patients received anti-infection treatment, of which 3 cases received only 2 g/kg intravenous immunoglobulin (IVIG), while the remaining 8 cases received a combination of IVIG and 2 mg/(kg·d) methylprednisolone. Among the 8 cases with coronary artery disease, 6 cases received low molecular weight heparin anticoagulation therapy. All patients were followed up in 2 weeks after being discharged, and their inflammatory markers had returned to normal by that time. The 8 cases with coronary artery disease and 3 cases with pneumonia showed significant improvement or back to normal at the 4-week follow-up. All patients had no new complications or comorbidities during follow-up of more than 3 months.Conclusions:MIS-C may present with Kawasaki disease-like symptoms, with or without gastrointestinal, neurological, or respiratory symptoms. Elevated inflammatory markers, abnormal coagulation function, and cardiac injury contribute to the diagnosis of MIS-C. IVIG and methylprednisolone were the primary treatments for MIS-C, and a favorable short-term prognosis was observed during a follow-up period of more than 3 months.
