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.

[Purpose]To analyze the trend of incidence rates of gallbladder cancer in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The incidence data of gallbladder cancer from 1972 to 2021 were collected from the Qidong Tumour Registry database,the crude incidence rate(CR),age-standardized rate by Chinese standard population(ASRC),age-standardized rate by world standard population(ASRW)of gallbladder cancer were calculated.Trend analysis was per-formed using Joinpoint 4.9.1.0 software to calculate the average annual percentage change(AAPC)of gallbladder cancer incidence rates,and time trend analysis was performed on the overall inci-dence rate by sex and age.[Results]A total of 1 369 cases of gallbladder cancer occurred in Qi-dong City from 1972 to 2021,accounting for 0.93％of all malignant tumors.The overall CR of gallbladder cancer was 2.44/105 in 50 years,ASRC was 0.88/105 and ASRW was 1.45/105.The truncated rate of 35～64 years old was 1.98/105,the cumulative incidence of gallbladder cancer at 0～74 years old was 0.16％,and the risk of cumulative incidence of gallbladder cancer was 0.16％.CR was slightly higher in women than that in men,but after standardization it was slightly higher in men than that in women.The sex ratio of CR,ASRC and ASRW was 0.89,1.07 and 1.06,respectively.With the increase of age,the incidence of gallbladder cancer was also increased.The age of onset was slightly increased in last 50 years.In last 50 years,there was an upward trend in the overall incidence of gallbladder cancer,the incidence both for men and women,and the inci-dence of each age group.[Conclusion]The incidence of gallbladder cancer in Qidong City has increased considerably during the past 50 years,and continuing attention should be paid to the prevention and treatment of gallbladder cancer especially for the key populations.

Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEO_x-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEO_x) by ester bonds. AEO_x-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEO_x-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEO_x-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEO_x-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective To evaluate the safety and effectiveness of different doses of epidural oxycodone injection for traction reaction during cesarean sections to determine the optimal dose.Methods Totally 119 cases of parturients who underwent cesarean sections from October 2023 to May 2024 were selected and randomly divided into groups A,B,C and D.All four groups of lying-in women received epidural injection after the umbilical cord was cut.Groups A,B and C were given oxycodone 3 mg,5 mg and 7 mg respectively,and group D was given an equal amount of normal saline.The primary outcomes were documentation of maternal vital signs and traction reaction during the surgery.Secondary outcomes included patient-controlled intravenous analgesia(PCIA)times within 48 hours and documentation of any postoperative adverse events within 24 hours.Results The comparison of in-tra?operative vital signs among the four groups of patients revealed no statistically significant differences.In groups A,B and C the incidence of traction reactions was significantly lower at 20％,17.2％and 3.3％,respectively,compared to group D at 53.3％,showing statistically significant differences(P<0.05).Additionally,the inci?dence of traction reaction in group C was significantly lower than in group A(P<0.05).Groups A,B and C pro?duced significantly better results than group D in terms of the duration of anesthesia.PCIA presses were substan?tially less in groups A and C than in group D(P<0.05),and group C had a significantly higher total incidence of adverse events than group A and group D(P<0.05).Conclusions Epidural injection of 3 mg,5 mg and 7 mg oxycodone has been proved to significantly reduce traction reaction during cesarean sections while minimally im?pacting intraoperative vital signs.This intervention has the potential to extend the duration of anesthesia,decrease the frequency of PCIA presses.Among these,7 mg is the most effective but has the highest incidence of adverse effects,requiring carefully post?operative monitoring.

Objective To observe the value of ultrasonic parameters of diaphragm motion combined with BODE index for predicting acute exacerbation of chronic obstructive pulmonary disease(COPD).Methods Eighty COPD patients were retrospectively collected and divided into stable group(n=45)and acute exacerbation group(n=35).Ultrasonic parameters of diaphragm motion,including diaphragm excursion(DE)under quiet breathing(QB)and deep breathing(DB),i.e.DEQB and DEDB were measured.The general data,ultrasound parameters of diaphragm motion,and BODE index scores were compared between groups.Then logistic regression analysis was used to identify factors which could be used to independently predict acute exacerbations of COPD.The predicting performance of ultrasound parameters of diaphragm motion,BODE index and their combination were evaluated with receiver operating characteristic(ROC)curve and the area under the curve(AUC).Results Compared with stable COPD group,acute exacerbation group had higher BMI and BODE index scores(both P＜0.05),as well as larger DEQB but smaller DEDB(both P＜0.05).DEDB and BODE index were both independent predicting factors of acute exacerbation of COPD,while increased DEDB indicated decreased risk of acute exacerbation(OR[95％CI]=0.673[0.493,0.918],P＜0.05),whereas increased BODE index suggested higher risk(OR[95％CI]=3.678[1.061,12.746],P＜0.05).AUC for DEDB and BODE index alone for predicting acute exacerbation of COPD was 0.788 and 0.799,respectively,and of their combination was 0.979,significant higher than that of each alone(both P＜0.05).Conclusion Ultrasonic parameters of diaphragm motion could be used to evaluate diaphragm function in COPD patients.Combination of DEDB and BODE index had better performances in predicting acute exacerbation of COPD.

Objective To evaluate the diagnostic value of preoperative positron emission computed-tomography(PET-CT)examination for lymph node metastasis in early non-small cell lung cancer(NSCLC).Methods A total of 232 early-stage NSCLC patients who underwent preoperative PET-CT examination and radical surgery for lung cancer in the hospital from January 2019 to April 2023 were selected.Clinical data,PET-CT examination results,and lymph node dissection pathology were collected to calculate the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of PET-CT diagnosis of NSCLC lymph node metastasis.The maximum standard uptake value(SUVmax)of the primary lesion and the predic-tive value of lymph node SUVmax for early NSCLC lymph node metastasis were evaluated by the receiver op-erating characteristic(ROC)curve.Results The accuracy of PET-CT examination in the diagnosis of NSCLC was 95.69％,the accuracy of lymph node metastasis diagnosis was 85.78％,the sensitivity was 35.56％,the specificity was 97.86％,the positive predictive value was 80.00％,and the negative predictive value was 86.32％.There was a statistically significant difference in the detection rate of PET-CT examination and path-ological results among pulmonary nodules of different natures and sizes(P＜0.01).For predicting lymph node metastasis in NSCLC,the cutoff point of SUVmax in the primary lesion was 3.83(P＜0.001),and the cutoff point of SUVmax in lymph nodes was 3.07(P＜0.001).Conclusion In early NSCLC,preoperative PET-CT examination has a high diagnostic accuracy for ground glass nodule lymph node metastasis,but its di-agnostic value for solid nodule lymph node metastasis is limited and insufficient to guide lymph node dissec-tion.Primary lesion SUVmax≥3.83 or lymph node SUVmax≥3.07 are high-risk factors for early lymph node metastasis in lung cancer.

Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital，in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points，and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases，including 1-21 cases in the learning stage，22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases，the postoperative bladder irrigation time reduced \[40.00 (26.00，44.50) h vs. 23.00(20.50，34.00) h vs. 23.50(14.75，40.75) h\]，with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\]，while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\]，catheter indwelling time \[70.0 (66.0，106.0) h vs. 71.0 (66.0，89.0) h vs. 66.0 (58.5，78.5) h\]，and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend，but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals，TUBVP is a worthy choice.
