Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective To investigate the effectiveness of the integrated schistosomiasis control programme in Sichuan Province during the stage moving from transmission interruption to elimination (2015—2023), so as to provide insights into formulation of the schistosomiasis control measures during the post-elimination stage. Methods Schistosomiasis control data were retrospectively collected from departments of health, agriculture and rural affairs, forestry and grassland, water resources, and natural resources in Sichuan Province from 2015 to 2023, and a database was created to document examinations and treatments of human and livestock schistosomiasis, and snail survey and control, conversion of paddy fields to dry fields, ditch hardening, rivers and lakes management and building of forests for snail control and schistosomiasis prevention. The completion of schistosomiasis control measures was investigated, and the effectiveness was evaluated. Results A total of 20 545 155 person-times received human schistosomiasis examinations in Sichuan Province during the period from 2015 to 2023, and 232 157 person-times were seropositive, with a reduction in the seroprevalence from 2.10% (44 299/2 107 003) in 2015 to 1.12% (9 361/837 896) in 2023 (χ² = 7.68, P < 0.001). The seroprevalence of human schistosomiasis appeared a tendency towards a decline in Sichuan Province over years from 2015 to 2023 (b = −8.375, t = −10.052, P < 0.001); however, no egg positive individuals were identified during the period from 2018 to 2023, with the prevalence of human Schistosoma japonicum infections maintained at 0. Expanded chemotherapy was administered to 2 754 515 person-times, and medical assistance of advanced schistosomiasis was given to 6 436 persontimes, with the treatment coverage increasing from 46.80% (827/1 767) in 2015 to 64.87% (868/1 338) in 2023. Parasitological tests for livestock schistosomiasis were performed in 35 113 herd-times, and expanded chemotherapy was administered to 513 043 herd-times, while the number of fenced livestock decreased from 121 631 in 2015 to 103 489 in 2023, with a reduction of 14.92%. Snail survey covered 433 621.80 hm² in Sichuan Province from 2015 to 2023, with 204 602.81 hm² treated by chemical control and 4 637.74 hm² by environmental modifications. The area of snail habitats decreased from the peak of 5 029.80 hm² in 2016 to 3 709.72 hm² in 2023, and the actual area of snail habitats decreased from the peak of 8 585.48 hm² in 2016 to 473.09 hm² in 2023. The mean density of living snails remained low across the study period except in 2017 (0.62 snails/0.1 m²). Schistosomiasis control efforts by departments of agriculture and rural affairs in Sichuan Province included conversion of paddy fields to dry fields covering 153 346.93 hm², hardening of 6 110.31 km ditches, building of 70 356 biogas digesters, replacement of cattle with 227 161 sets of machines, and captive breeding of 21 161 070 livestock from 2015 to 2023, and the control efforts by departments of water resources included rivers and lakes management measuring 5 676.92 km and renovation of 2 331 irrigation areas, while the control efforts by departments of forestry and grassland included building of forests for snail control and schistosomiasis prevention covering 23 913.33 hm², renovation of snail control forests covering 8 720 hm² and newly building of shelterbelts covering 764 686.67 hm². All 63 endemic counties (cities and districts) had achieved the criterion for schistosomiasis elimination criteria in Sichuan Province by the end of 2023. Conclusion Following the integrated control efforts from 2015 to 2023, remarkable achievements have been obtained in the schistosomiasis control programme in Sichuan Province, with all endemic counties successfully attaining the schistosomiasis elimination target at the county level.

Objective:To explore the effectiveness of find-organize-clarify-understand- select-plan-do-check-act (FOCUS-PDCA) cycle management in improving the accuracy of Nutritional Risk Screening 2002 (NRS 2002) scoring in inpatients.Methods:This study was a retrospective study. Data from a continuous quality improvement project, namely Improving the Accuracy of Nutritional Risk Screening for Inpatients from People's Hospital of Longhua in 2021 were selected. The NRS 2002 scores of newly admitted patients from 8 departments with relatively high nutritional risk (departments of gstroenterology, neurology, nephrology, respiratory medicine, oncology and hematology, neurosurgery, gastrointestinal surgery, and critical care medicine) from April 10, 2021 to April 29, 2021 (before intervention) were collected. The NRS 2002 scores were evaluated by a multidisciplinary nutrition support team in terms of accuracy and error types. Possible issues in the process of nutritional screening were analyzed and mitigated using the FOCUS-PDCA cycle management method. The NRS 2002 scores from July 18, 2021 to August 8, 2021 (after intervention) were collected in real time to summary the data on accuracy and error types and to evaluate the effect of FOCUS-PDCA.Results:The accuracy of NRS 2002 score in the 8 departments was increased from 52.97% (294/555) to 81.13% (473/583) after intervention, and the difference was statistically significant ( χ2=102.606, P<0.001). The accuracy of nutritional status impairment score was 64.14% before intervention, compared with 90.57% after intervention ( χ2=114.484, P<0.001). The accuracy of disease severity score was 78.56%, compared with 89.54% after intervention( χ2=25.736, P<0.001). The false-negative rate was 68.02% before intervention and 31.87% after intervention, and the difference was statistically significant ( χ2=31.501, P<0.001). Conclusion:FOCUS-PDCA can improve the accuracy of NRS 2002 scoring in inpatients, reduce the risk of failing to identify patients at nutritional risk, and contribute to further nutritional diagnosis and treatment.

Objective: To explore the brain-predicted age difference (Brain-PAD) in patients with type 2 diabetes mellitus (T2DM) by a machine learning prediction model based on structural magnetic resonance ( sMRI) in the Southwest University Adult Lifespan Dataset (SALD) , and to reveal the relationship between Brain-PAD and dura- tion of T2DM and cognition . Methods: Group comparisons about demographic variables and cognitive function were conducted respectively in local database of 104 T2DM patients and 83 healthy controls (HC) . The prediction model via Gaussian process regression (GPR) was constructed by training sMRI data of 329 healthy volunteers in SALD , then its performance was validated and evaluated . Furthermore , Brain-PAD ( predicted age-chronological age) in the local database was calculated . Group comparisons of Brain-PAD between T2DM patients and HCs were conducted by Mann-Whitney U test. Finally , Pearson correlation coefficient (r) was calculated between Brain-PAD and duration of disease and cognition . Results: Poor performance in auditory verbal learning test (AVLT)-delayed recall , AVLT-recognition , symbol digital modalities test (SDMT) (P < 0. 05) , and increased Brain-PAD were ob- served in T2DM patients , compared with HCs [1 . 619 ( - 4. 001 , 8. 272) years vs - 1 . 289 ( - 4. 128 , 4. 134) years , Z = 2. 056 , P = 0. 034] . Notably , the median of Brain-PAD in T2DM group was positive , indicating that the brain of T2DM patient maybe relatively “older”than his chronological age . Brain-PAD in T2DM group was as- sociated with performance in AVLT-immediate recall ( r = 0. 291 , P = 0. 003) , AVLT-delayed recall ( r = 0. 248 , P = 0. 011) , SDMT( r = 0. 376 , P = 0. 001) and trail making test (TMT)-A ( r = - 0. 206 , P = 0. 036) . However , the relationships between Brain-PAD and duration of T2DM were not explored . Conclusion Decreased cognitive function in patients with T2DM is demonstrated in this study . The machine learning prediction model based on sMRI supports the identification of brain aging objectively in patients with T2DM .

AIM:To investigate the effect of fenofibrate(FF)on the heart of rats with high-altitude heart dis-ease-induced right ventricular hypertrophy(H-RVH),and to explore the mechanisms and associated signaling pathways.METHODS:A total of 36 six-week-old male SD rats were randomly divided into control,model(H-RVH),and FF inter-vention(H-RVH+FF)groups with 12 rats each.A rat model of H-RVH was established by single subcutaneous injection of Sugen 5416(20 mg/kg)and exposure to a hypoxic condition(5 000 m above sea level)for 21 d in all groups except the control group.The rats in H-RVH+FF group were given FF(60 mg·kg-1·d-1)through gavage,while those in control and model groups received equal volume of saline once daily for 21 d.Rat heart gross morphology was observed,and the heart volume and weight,right ventricular weight and other hypertrophy indexes were measured in each group at the end of the experiment.A right heart floating catheter was used for measuring pulmonary artery and right ventricular pressure.Cardi-ac function was checked through cardiac ultrasonography.The serum levels of atrial natriuretic peptide(ANP),N-termi-nal pro-brain natriuretic peptide(NT-proBNP),free fatty acids(FFA),and myocardial tissue glucose(Glu)in all groups of rats were detected.The protein expression of peroxisome proliferator-activated receptor α(PPARα),fatty acid binding protein 1(FABP1),carnitine palmitoyl transferase 1a(CPT1a),pyruvate dehydrogenase kinase(PDK),and pyruvate dehydrogenase(PDH)were detected through Western blot.RESULTS:(1)Compared with the control group,the H-RVH group showed a significant increase in heart morphology and weight and increases in heart weight/body weight(HW/BW),heart volume,right ventricular weight/heart weight(RVW/HW),and Fulton index(FI)(P<0.05).Cardiac mor-phology,volume,heart weight,and HW/BW significantly decreased in the fenofibrate intervention group compared with the H-RVH group(P<0.05).RVW/HW and FI also decreased.(2)The right heart float catheter test showed that the mean right ventricular pressure(mRVP)and mean pulmonary artery pressure(mPAP)significantly increased in the H-RVH group compared with the control group(P<0.01).The increases in mRVP and mPAP were reversed in rats in the fe-nofibrate intervention group compared with the H-RVH group.(3)Cardiac ultrasonography showed that compared with the control group,the H-RVH group had significantly increased right ventricular anterior wall(RVAW)and right ventricular posterior wall(RVPW)thickness(P<0.01),significantly decreased right ventricular end-diastolic diameter(RVEDD),and right ventricular end-diastolic length(RVEDL)(P<0.01).In addition,pulmonary artery acceleration time(PAAT)was reduced,ejection time(PAET)was prolonged,and PAAT/PAET ratio decreased(P<0.01).Compared with the H-RVH group,the fenofibrate intervention group showed significant decreases in RVAW and RVPW(P<0.05),increases in RVEDD and RVEDL,and an increase in PAAT/PAET ratio.(4)The kit assay showed that the levels of ANP and NT-Pro BNP in serum were significantly higher in the H-RVH group than in the control group(P<0.05),while the levels of both were lower in the fenofibrate intervention group.The levels of serum FFA and myocardial tissue Glu levels(P<0.05)were significantly higher in the H-RVH group than in the control group.The levels of serum FFA and myocardial tissue Glu level were significantly lower in the fenofibrate intervention group than in the H-RVH group(P<0.05).(5)Western blot results showed that the expression levels of PPARα,FABP1,CPT1a,and PDH in the myocardial tissues of rats in the H-RVH group were significantly reduced(P<0.01),whereas the expression level of PDK significantly increased relative to those of the control group(P<0.01).All the effects on the above indices in the H-RVH group can be significantly re-versed by fenofibrate intervention(P<0.05).CONCLUSION:Fenofibrate exerts a protective effect on the hearts of rats with right ventricular hypertrophy associated with high-altitude heart disease by activating PPARα/FABP1/CPT1a,en-hancing fatty acid oxidation,inhibiting PDK,and activating PDH to promote the aerobic oxidation of glucose.Hence,the medication can ameliorate glucose-lipid metabolism disorders.

Objective:To investigate the predictive value of neutrophil extracellular traps (NETs) on the prognosis of patients with epidermal growth factor receptor (EGFR) wild-type lung adenocarcinoma.Methods:A total of 132 surgical paraffin specimens of EGFR wild-type lung adenocarcinoma diagnosed at the Tumor Hospital Affiliated to Xinjiang Medical University from January 2016 to December 2023 and 12 pairs of cancer and paracancerous fresh tissues from patients with EGFR wild-type lung adenocarcinoma diagnosed in March-July 2024 were collected with their clinical information. Western blotting and immunofluorescence were used to detect the expression levels of citrullinated histone H3 (CitH3) and myeloperoxidase (MPO) in cancerous and paraneoplastic tissues. Immunohistochemistry was used to detect the infiltration of PD-L1, CD4 + T cells and CD8 + T cells in the tumors. The clinical and prognostic correlations between NETs and EGFR wild-type lung adenocarcinoma patients were analyzed. Results:The expression of MPO ( P＜0.001) and CitH3 ( P=0.009) was significantly increased in the tumors compared with the paracancerous tissues. The rate of high expression of NETs in cancer tissues was higher in patients with EGFR wild-type lung adenocarcinoma who were in stage Ⅲ and Ⅳ, with lymph node metastasis, distant metastasis, pleural invasion, high expression of Ki-67, low expression of CD8 + T, and lowered lymphocyte counts when compared to paraneoplastic tissues ( P＜0.05). Patients were stratified based on TNM stage Ⅱb for prognostic analysis. Kaplan-Meier univariate analysis showed that the median overall survival (OS) (stage Ⅰ to Ⅱb: 47 vs 87 months; stage Ⅲ to Ⅳ: 27 months vs not reach) and the median disease-free survival (DFS) (stage Ⅰ to Ⅱb: 42 vs 78 months; stage Ⅲ to Ⅳ: 18 vs 39 months) of patients with high expression of NETs in stage Ⅰ to II b and stage Ⅲ to Ⅳ were lower than those with low expression (stage Ⅰ to Ⅱb: OS, P＜0.001; DFS, P＜0.001; stage Ⅲ to Ⅳ: OS, P=0.001; DFS, P=0.022). The OS (stage Ⅰ to Ⅱb: HR=3.513, 95% CI: 1.966-6.277, P＜0.001; stage Ⅲ to Ⅳ: HR=3.215, 95% CI: 1.324-7.806, P=0.010) and the DFS (stage Ⅰ to Ⅱb: HR=2.478 ,95% CI: 1.396-4.400, P=0.002; stage Ⅲ to Ⅳ: HR=2.248, 95% CI: 1.089-4.638, P=0.028) in the group with high expression of NETs in either stage Ⅰ to Ⅱb or stage Ⅲ to Ⅳ were significantly shorter than those in the group with low expression. Conclusion:The EGFR wild-type lung adenocarcinoma patients with high expression of NETs have relatively shorter DFS and OS, which are independent risk factors for the prognosis of patients with EGFR wild-type lung adenocarcinoma, and are likely to be the potential biomarkers for the diagnosis and treatment of EGFR wild-type lung adenocarcinoma.

AIM:To analyze the expression of se-creted phosphoprotein 1(SPP1)and programmed cell death-ligand 1(PD-L1)in SMARCA4-deficient non-small cell lung cancer,and to provide a scientif-ic basis for the study of the follow-up treatment of this rare pathological type of lung cancer.METH-ODS:The clinical and pathological characteristics of 12 patients with this disease were analyzed retro-spectively,and the patients were divided into two groups of adenocarcinomas and poorly differentiat-ed carcinomas according to their morphological characteristics,and the relationship between the expression of SPP1 and PD-L1 was analyzed in the two groups.RESULTS:SPP1 expression was detect-ed in all patients and Its expression level was signif-icantly higher in the poorly differentiated carcino-ma group compared with the adenocarcinoma group(P=0.015);PD-L1 expression was found in 6/7 patients(5 cases were not measured),compared with the adenocarcinoma group,PD-L1 was also highly expressed in the poorly differentiated carci-noma group(P=0.048)and the PD-L1 difference be-tween the two groups suggested that the results were similar to those of SPP1.CONCLUSION:SMARCA4-deficient non-small cell lung cancer has high positive expression of SPP1 and PD-L1.It was more pronounced in patients with poorly differenti-ated carcinoma.There may be a positive correla-tion between SPP1 and PD-L1 expression in SMAR-CA4-deficient non-small cell lung cancer and the mechanism of the correlation needs to be further verified in subsequent studies.

Objective:It aims to deepen the understanding of the coupled and coordinated development of health investment and economic growth,and to provide a scientific basis for the development of health policies for China's ten largest urban ag-glomerations.Methods:Based on the provincial panel data of ten major urban agglomerations from 2013 to 2022,entropy weight method,coupled coordination degree model,spatial autocorrelation model and quantile regression model are used for analysis.Results:In observation period,the level of two-system coupling and coordination grows from 0.397 in 2013 to 0.645 in 2022;the global Moran's I decreases from-0.020 to-0.357.In the dynamic leapfrog analysis,22.2%of provinces and munici-palities experience positive leapfrogging,while 16.7%of provinces and municipalities show negative leapfrogging.Baesd on lo-calised Moran Index,the quantile regression results show that the proportion of the people in higher education,the level of ur-banization and the level of labor force have a positive influence on the level of coupling and coordination between these two sys-tems,with the β coefficient showing a tendency of increasing and then decreasing;medical research institutes have a negative influence on the level of coupling and coordination between these two systems on the 0.1-0.3 quantile;the level of foreign invest-ment has a positive influence on the 0.1 quantile,and the 0.6-0.8 quartile has a negative effect.GDP per capita has a weak ef-fect on the level of coordination between these two systems.Conclusion:The two-system coupling and coordination level of the ten major urban agglomerations shows an overall increase,but there are regional differences,and it is affected by the integra-tion of science and education,economic level and human resources.
