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 explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

Objective:To analyze the factors affecting quality of life in patients with early esophageal cancer after endoscopic submucosal dissection (ESD) .Methods:Convenience sampling was used to select 162 early esophageal cancer patients with ESD in Cangzhou Central Hospital from August 2021 to July 2023 who had an on-time follow-up six months as study subjects. General Information Questionnaire and Quality of Life Instruments for Cancer Patients-Esophageal Cancer (QLICP-ES) were used to investigate the patients. Factors affecting the quality of life of patients after ESD for early esophageal cancer were analyzed using univariate analysis and multiple linear regression analysis.Results:Univariate analysis showed statistically significant differences in QLICP-ES scores among patients with different gender, age, marital status, annual income, medical payment method, concomitant diseases, degree of infiltration, vascular invasion, surgical complications, and positive margins ( P<0.05). Multiple linear regression analysis showed that age, marital status, concomitant diseases, vascular invasion, surgical complications, and positive margins were the factors influencing the QLICP-ES scores of patients with ESD for early esophageal cancer, and the differences were statistically significant ( P<0.05) . Conclusions:Quality of life at six months after ESD in patients with early esophageal cancer is at an intermediate to high level. Patients of advanced age, unmarried/divorced/widowed, concomitant diseases, vascular invasion, surgical complications and positive margins have low QLICP-ES scores after ESD for early esophageal cancer. It is recommended that clinical attention be focused on these factors and that targeted nursing measures be taken when necessary.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.

Objective:To establish a paired organoid culture system for primary pancreatic cancer lesions and liver metastatic lesions in mice, and to investigate their morphological and biological behaviors.Methods:C57BL/6 mice aged 6 to 8 weeks were selected. Pancreatic cancer PANC02 cells carrying luciferase were injected into the pancreatic tail. After monitoring the formation of liver metastases using an in vivo imaging system, mice were sacrificed, and paired primary pancreatic cancer lesions and liver metastatic lesions were extracted and cultured in an in vitro organoid culture system. The formation process of organoids was observed under an inverted phase-contrast microscope. Hematoxylin and eosin staining was used to examine the morphological structure of the organoids. The expression of epithelial cell marker CK19 and proliferation marker Ki67 in the organoids was detected by immunohistochemistry and immunofluorescence staining. The expression of invasion markers N-cadherin, E-cadherin, vimentin, snail, and MMP9 was assessed by Western blotting and immunohistochemistry. The drug sensitivity of organoids to gemcitabine was evaluated using the CellTiter-Glo ? 3D Cell Viability Assay, and the half-maximal inhibitory concentration (IC 50) of the organoids was calculated. Results:A spontaneous liver metastasis model of pancreatic cancer in mice was successfully established, along with a paired organoid culture system for primary pancreatic cancer lesions and liver metastatic lesions. The organoids grew in a spherical shape and could be passaged up to 10 generations in vitro. Both liver metastatic lesion organoids and primary pancreatic cancer lesion organoids exhibited lumen-like structures, expressed the epithelial cell marker CK19, and the proliferation marker Ki67, with a significantly higher positive ratio of Ki67 in the liver metastatic lesions compared to the primary pancreatic cancer lesions. The expression levels of invasion markers N-cadherin, vimentin, snail, and MMP9 were significantly higher in liver metastatic organoids than in primary pancreatic cancer organoids, whereas the expression level of E-cadherin was significantly lower in liver metastatic organoids. The IC 50 value of gemcitabine for liver metastatic organoids was 165.0 nM, higher than the 108.5 nM for primary pancreatic cancer organoids. Conclusions:A stable, passagable organoids of primary pancreatic cancer lesions and liver metastatic lesions in mice were successfully established.
