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.

Forensic medicine has been designated as a first-level discipline,presenting new opportunities and challenges for the development of forensic medicine.Since the 1980s,the establishment of foren-sic medicine discipline and the cultivation of high-level forensic talents have become hot topics in the development of forensic medicine in China.Since the 13th Five-Year Plan,the forensic team of Shanxi Medical University has been aiming at the forefront,proposing the development goals of"Five First-class"and the discipline development path"Six Major Achievements".It has selected benchmark disci-plines,identified gaps in disciplinary development,unified thoughts,formulated completion timelines,concentrated superior resources,assigned tasks to individuals,and created an"Organized Fill-in-the-Blank Format"forensic medicine discipline construction model with the characteristics of the new era.The construction model of forensic medicine has achieved good results in the goals,discipline frame-work,scientific research,talent cultivation,discipline team and platform construction,forming a rela-tively complete discipline construction and management system,and accumulating valuable experience for the construction of first-level discipline and high-level talent cultivation of forensic medicine.

Objective To preliminarily investigate the safety and efficacy of percutaneous microwave ab-lation(MWA)in patients with advanced breast cancer involving the skin or nipple-areola complex(NAC).Methods This study included breast cancer patients with skin or NAC involvement treated at the Fifth Medical Center of the Chinese PLA General Hospital from January 2011 to August 2024.Patients underwent percutaneous MWA with water isolation technique to protect surrounding tissues.Clinical data were retrospectively collected,and the technical success rate,complications,prognosis,patient satisfaction with breast aesthetics,and quality of life improvement were analyzed.Results A total of 19 patients(24 lesions)meeting the inclusion and ex-clusion criteria were analyzed.The cases included 4 with T4N0M0,2 with T4N1M0,3 with T4N2M0,1 with T4N3M0,1 with T4N2M1,and 8 with T4N3M1.The average diameter of the 24 lesions was(4.9±3.4)cm,with an average of(1.6±0.6)ablation sessions per lesion.The median ablation time was 36.9(26.1,61.7)minutes,and the median ablation energy was 84.2(45.6,149.2)kJ.The technical success rate was 100%.Postoperatively,7 patients(7/19,36.8%)experienced skin burns around the lesion or nipple shedding,all of which healed naturally.The median overall survival was 35.0(17.0,45.5)months,and the median recur-rence-free survival was 17.0(11.0,38.5)months.Patient satisfaction with post-treatment breast aesthetics was 89.5%,and all patients reported significant improvement in their quality of life.Conclusions Percutane-ous microwave ablation for breast cancer involving the skin or NAC was preliminary demonstrates to be safe and effective,suggesting its potential as a viable treatment option for patients with inoperable breast cancer.

Objective To explore the role of secreted phosphoprotein 1(SPP1)and myeloid differentiation primary response 88(MYD88)in morphine-induced cardiomyocyte apoptosis.Methods A morphine addiction model was established in Sprague-Dawley(SD)rats.Twelve SD rats were randomly assigned to the normal saline(NS)group or the morphine-dependent(DAM)group.Histopathological analysis was employed to observe and compare myocardial tissue morphology between the two groups.Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL)staining was performed to assess the number of apoptotic cells in each group.The expression levels of SPP1 and MYD88 were evaluated using immunohistochemistry.Quantitative real-time poly merase chain reaction(RT-qPCR)and Western blot were used to detect the mRNA and protein expression of SPP1,MYD88,Bax,Bcl2,Caspase-3,and Caspase-9.Simultaneously,Western blot analysis was used to detected the expression of Cleaved Caspase-3 and Cleaved Caspase-9 proteins.In vitro,SPP1 expression was knocked down in primary neonatal rat cardiomyocytes(NRCMs),and cells were divided into three groups:control(CON),morphine treated(DA),and shSPP1#3+DA.Cell viability was assessed using the CCK-8 assay,and apoptosis rates were determined by flow cytometry.Results HE and TUNEL staining of myocardial tissues from morphine-addicted SD rats revealed that,compared with the NS group,myofibrils in the DAM group exhibited partial disruption and a significant increase in apoptotic cells(P<0.05).Western blot and RT-qPCR analyses demonstrated that,relative to the NS group,the mRNA and protein levels of SPP1,MYD88,Bax,Caspase-3,and Caspase-9 were significantly upregulated in the DAM group(P<0.05),whereas Bcl2 expression was significantly downregulated at both mRNA and protein levels(P<0.05),and the protein expression levels of Cleaved Caspase-3 and Cleaved Caspase-9 were also increased.with all differences being statistically significant.In NRCMs following morphine intervention,cell viability in the DA group was markedly reduced compared to the CON group(P<0.05),accompanied by a signifi-cant increase in apoptosis rate(P<0.05).Consistently,Western blot and RT-qPCR results showed elevated mRNA and protein expression of SPP1,MYD88,Bax,Caspase-3,and Caspase-9 in the DA group(P<0.05),along with decreased Bcl2 expression(P<0.05).The protein expression levels of Cleaved Caspase-3 and Cleaved Caspase-9 were elevated simultaneously.In contrast,the shSPP1#3+DA group exhibited opposing trends compared to the DA group,with statistically sig nificant differences(P<0.05).Conclusion SPP1 and MYD88 play critical roles in mediating morphine-induced cardiomyocyte apoptosis,and silencing SPP1 has been shown to significantly reduce the extent of cardiomyocyte apoptosis following morphine exposure.

Objective:To evaluate the efficacy and safety of blinatumomab in adult patients with relapsed/refractory(R/R)or measurable residual disease(MRD)positive B-cell acute lymphoblastic leukemia(B-ALL)in the real world.Methods:The clinical data of 30 B-ALL patients received at least 1 course of blinatumomab therapy in the Chinese PLA General Hospital from January 1st,2021 to December 31st,2023 were retrospectively analyzed,including pre-treatment baseline clinical feature,post-treatment complete response(CR),CR with partial hematologic recovery(CRh),CR with incomplete hematologic recovery(CRi),complete MRD response rate,MRD response rate(MRD＜10-4),overall survival(OS),and disease-free survival(DFS),as well as drug-related adverse reactions.Results:Among 5 patients who were not assessed 4 were MRD negative and 1 did not receive bone marrow biopsy.In the R/R B-ALL group(13 cases),11 patients achieved CR/CRh/CRi and 10 patients achieved complete MRD response.In MRD+group(12 cases),9 patients achieved overall MRD response and 7 patients achieved complete MRD response.The median follow-up time was 8.4(95％CI:6.3-10.4)months.The median OS was 15.5(95％CI:0.7-30.3)months in the R/R group,while not reached in the MRD+group.The median DFS of the two groups were not reached.Drug-related adverse reactions occurred in 22 patients,and pyrexia was the most common(13 cases).Grade ≥3 adverse reactions occurred in 15 patients,and neutropenia was the most common(9 cases).Cytokine release syndrome occurred in 6 patients,including 5 cases with grade 1 and 1 case with grade 3.No patients interrupted therapy or died due to drug-related adverse reactions.Conclusion:Blinatumomab is effective in the treatment of R/R or continuous MRD+B-ALL with acceptable adverse reactions.
