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.

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.

Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the effect of KRAS,NRAS and BRAF gene mutations on the efficacy of pre-operative short-course radiotherapy combined with chemotherapy and postoperative liver metastasis in patients with stage Ⅱ～Ⅲ mid-low rectal cancer.Methods:The clinical data of 149 patients with stage Ⅱ～Ⅲ low rectal cancer admitted to Dongnan Hospital of Xiamen University from January 2017 to June 2020 were retrospectively analyzed.All patients received neoadjuvant therapy with preoperative short-course radiotherapy combined with chemotherapy and radical surgery,and were followed up until June 30,2023.The mutations of KRAS,NRAS and BRAF genes were de-tected by pathological tissue before surgery.The effect of neoadjuvant therapy was evaluated according to tumor re-gression grade(TRG).The risk factors of postoperative liver metastasis were analyzed by Logistic multivariate analysis.Results:There were 44 cases of KRAS,10 cases of NRAS and 12 cases of BRAF gene mutation in 149 patients with stage Ⅱ～Ⅲ low rectal cancer,and the mutation rates were 29.53%,6.71%and 8.05%.The incidence of positive vas-cular invasion in patients with KRAS gene mutation was higher than negative(P＜0.05).In NRAS mutation patients,the incidence of positive lymph node metastasis was higher than negative(P＜0.05),and the incidence of maximum tumor diameter≥5 cm was higher than that of maximum tumor diameter＜5 cm(P＜0.05).The clinical stage of BRAF muta-tion was higher in stage Ⅲ than in stage Ⅱ(P＜0.05),and the incidence of positive lymph node metastasis was higher than negative(P＜0.05).During the follow-up period,liver metastasis occurred in 42 patients,and the liver metastasis rate was 28.18%.The KRAS,NRAS and BRAF gene mutations in the effective group were 25.81%,2.15%and 3.23%,lower than those in the ineffective group(35.71%,14.29%and 17.07%,P＜0.05).Multiple factors found clinical stage Ⅲ(OR=10.620,95%CI:2.645～22.575),lymph node metastasis was positive(OR=8.774,95%CI:1.878～19.645),neoadju-vant therapy failed(OR=3.373,95%CI:1.014～11.218),KRAS gene mutation(OR=6.245,95%CI:1.876～20.789),BRAF gene mutation(OR=9.497,95%CI:1.754～19.335)were independent risk factors for postoperative liver metastasis of stage Ⅱ～Ⅲ mid-low rectal cancer.Conclusion:Mutations in the KRAS and BRAF genes of middle are associated with poorer efficacy of neoadjuvant therapy in patients with stage Ⅱ～Ⅲ mid-low rectal cancer and are also indepen-dent risk factors for postoperative liver metastasis.

Objective:This study aims to investigate the risk factors of venous thromboembolism(VTE)in patients with chronic heart failure(CHF),and establish a model for predicting the risk of VTE.Methods:A nested case-control study was conducted on CHF patients admitted in Pengzhou People's Hospital between June 2022 and June 2023.A total of 66 patients were diagnosed with VTE among the 960 CHF patients.Then another 66 patients paired by age and gender to those with VTE were selected from the remaining non-VTE patients as control group.Gener-al data,D dimer(D-D),thrombin-antithrombin complex(TAT),plasmin-α2-antiplasmin complex(PIC),tissue plasminogen activator-inhibitor complex(t-PAIC),thrombomodulin(TM)and Padua score were compared between two groups.Multivariate Logistic regression analysis was used to screen the independent risk factors of VTE in CHF patients.The receiver operating characteristic(ROC)curve analysis was applied to assess the efficacy of each indicator in predicting the risk of VTE in CHF patients.Results:Compared to patients in the non-VTE group,those in the VTE group had significantly higher D-D[3.26(1.87,6.19)mg/L vs.0.81(0.56,1.26)mg/L],TAT[5.60(4.90,8.80)ng/ml vs.2.60(1.70,3.30)ng/ml],TM[16.40(13.50,20.03)TU/ml vs.9.65(7.60,11.20)TU/ml],PIC[1.24(0.94,1.68)μg/ml vs.0.84(0.65,1.22)μg/ml],t-PAIC[12.60(9.38,17.05)ng/ml vs.7.70(5.53,9.70)ng/ml],proportion of atrial fibrillation/flutter(54.5％vs.22.7％)and Padua score[4(3,4)points vs.3(2,3)points](P＜0.001 all),and significantly lower lymphocyte count[0.99(0.60,1.38)×109/Lvs.1.20(0.76,1.67)×109/L,P=0.020].Multivariate Logistic regression analysis indicated that after adjusting confounders,TM(OR=2.456,95％CI 1.389～14.296,P=0.012)and Padua score(OR=3.257,95％CI 1.270～13.073,P=0.037)were independent risk factors for VTE in CHF patients.A predictive model was constructed using above-mentioned two indexes.The area under the ROC curve(AUC)of the combined prediction was 0.941(95％CI 0.901～0.980),which was significantly higher than those of TM(AUC=0.889,95％CI 0.833～0.945)and Padua score(AUC=0.801,95％CI 0.731～0.871)alone(Z=2.672,4.063,P=0.008,＜0.001).Conclusion:Padua score and TM were independent risk factors for VTE in CHF patients,and their combined detec-tion could better predict the risk of VTE in these patients.

Aim To explore the mechanism of Lycium barbarum glycopeptide(LbGP)improving aging in rat primary ovarian granulosa cells.Methods This study divided the cells into a normal group,a DOX group,and four different LbGP concentration treatment groups post-DOX intervention.Results Cell proliferation was assessed using CCK-8,EDU,and Ki67 assays,while aging markers and mitochondrial function-related fac-tors were detected using immunofluorescence and West-ern blotting.The results showed that,compared to the DOX group,LbGP treatment significantly increased cell viability(P＜0.05)and promoted proliferation(P＜0.05).Post LbGP treatment,the β-galactosidase-posi-tive area in cells was significantly reduced compared to the DOX group(P＜0.05).Immunofluorescence re-sults indicated that,compared to the DOX group,levels of p21 and γH2AX significantly decreased(P＜0.05),while pRB increased(P＜0.05)after LbGP treatment.Western blot results showed that,compared to the DOX group,the aging phenotype proteins p21 and p53 significantly decreased(P＜0.05),and pRB notably increased(P＜0.05)in the LbGP treatment group.The release of cytC into the cytoplasm and the activated caspase-9 significantly decreased(P＜0.05);levels of CAMKK2,pAMPK,and mitochondrial calcium homeostasis regulator MCU increased(P＜0.05);nuclear energy metabolism-related proteins SirT1,PGC1α/β and ATP5A1 significantly increased(P＜0.05);compared to the DOX group,ROS levels significantly decreased after LbGP treatment(P＜0.05).Conclusions The results suggest that LbGP can ameliorate DOX-induced aging in rat primary ovar-ian granulosa cells,potentially through the upregulation of the CAMKKβ/AMPK signaling pathway,thereby im-proving mitochondrial calcium homeostasis and increas-ing the expression levels of cell energy metabolism-re-lated regulatory proteins.This provides an experimen-tal basis for LbGP's potential role in supporting the im-provement of ovarian function.

Objective To investigate the clinical characteristics of women with abnormal uterine bleeding(AUB)in sub-plateau regions and analyze the factors affecting their treatment methods.Methods AUB patients who were hospitalized from Jan 1,2018 to Dec 31,2022,in a sub-plateau region(Yongping County People's Hospital of Yunnan Province)with an average altitude of 1 620 meters were selected.The general clinical characteristics of the patients were summarized,and patients were classified into two categories(with or without uterine structural lesion)and nine subtypes(PALM-COEIN)according to the FIGO recommended etiological classification guidelines.Then the patients were divided into groups based on the presence or absence of uterine structural lesions,ethnic group(Han and minority),conservative drug treatment and surgical treatment groups,blood transfusion and non-blood transfusion groups.Binary Logistic regression analysis was used to identify factors affecting treatment methods.Results A total of 481 AUB patients enrolled,and the delayed consultation rate was as high as 80.46%,and the proportion of overweight and obese patients was 49.90%,which was higher than the average level among Chinese women.The main cause was AUB-O(AUB-ovulatory dysfunction),accounting for 78.59%of cases,the proportion of patients with delayed medical treatment was higher than those without delayed medical treatment(82.17%vs.74.47%).Patients who received blood transfusion were significantly younger,had lower hemoglobin(HGB)levels,fewer pregnancies,and lower BMI compared to those in the non-blood transfusion group(P<0.05).Univariate analysis showed that the surgical treatment group had older age,longer onset time,higher HGB levels,more pregnancies and deliveries,higher BMI,a higher proportion of Han ethnicity patients,lower rates of non-blood transfusion,higher rates of hypertension,and more uterine structural lesions compared to the conservative drug treatment group.Multivariate regression analysis revealed that blood transfusion treatment reduced the probability of surgical treatment.Age and uterine structural lesions were risk factors for requiring surgical treatment,for each additional year of age,the risk of undergoing surgical treatment increased by 10%.The risk of requiring surgical treatment for patients with uterine structural lesions was 2.987 times higher than for those without.Conclusion AUB patients in this sub-plateau regions have a high rate of delayed consultation and a high proportion of overweight and obesity,with AUB-O being the primary cause.Older age and the presence of uterine structural lesions were risk factors for requiring surgical treatment.

Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by anorexia.Methods:This cross-sectional study included patients registered in the RealDTC study from May 2023 to December 2023. Demographic data, COPD Assessment Test (CAT) score, modified Medical Research Council (mMRC) dyspnea questionnaire score, Clinical COPD Questionnaire (CCQ) score, forced expiratory volume in one second (FEV 1), forced expiratory volume in the first second predicted of percentage (FEV 1%pred), FEV 1/forced vital capacity (FVC), Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade, GOLD group, number of acute exacerbations and hospitalizations in the past year, and score of the Functional Assessment of Anorexia Cachexia Therapy-Anorexia/Cachexia Subscale-12 (FAACT-A/CS-12) were collected. Patients with a FAACT-A/CS-12 score ≤30 were diagnosed as having anorexia. Multivariate logistic regression analysis was used to evaluate the influencing factors of anorexia in COPD patients. Results:A total of 617 COPD patients were included, of whom 109(17.7%) had anorexia. Compared with non-anorexia patients, COPD patients with anorexia had higher age, CAT, mMRC and CCQ scores, and more acute exacerbations and hospitalizations in the past year, while body mass index, FEV 1, FEV 1%pred and FEV 1/FVC were lower (all P<0.05). The proportions of patients with primary education or below, GOLD 3-4 grade and GOLD E group were higher in COPD patients with anorexia (all P<0.05). Logistic regression analysis showed that a CAT score of 10-<20 [odds ratio ( OR)=4.017, 95% confidence interval ( CI): 1.673-59.645], a CAT score of 20-<30 ( OR=9.686, 95% CI: 3.777-24.842), a CAT score of ≥30 ( OR=78.286, 95% CI: 7.654-800.689) and ≥1 hospitalization in the past year ( OR=2.050, 95% CI: 1.292-3.254) were independent risk factors for anorexia in COPD patients (all P<0.05). Conclusions:COPD patients with anorexia have poor lung function, high symptom burden and high risk of acute exacerbation. Clinicians should pay attention to the management of COPD patients with anorexia and take corresponding intervention measures.
