Objective: To analyze the trend in burden of rheumatoid arthritis (RA) in China from 1990 to 2021, so as to provide insights into reducing the RA burden in China. Methods: Data of Global Burden of Disease Study 2021 were collected, and the incidence, mortality and disability-adjusted life years (DALY) of RA in China from 1990 to 2021 were analyzed and compared with global and different Socio-demographic Index (SDI) regions. The trend in burden of RA was analyzed using average annual percent change (AAPC). Results: The crude incidence rates of RA in China increased from 10.87/105 in 1990 to 17.38/105 in 2021, the crude mortality rates increased from 0.41/105 to 0.72/105, and the crude DALY rates increased from 34.26/105 to 58.61/105, with the increases of 59.98%, 77.95% and 71.06%, respectively. From 1990 to 2021, the standardized incidence rates of RA in China showed an increasing trend (AAPC=0.545%, P<0.05), the standardized mortality rates showed a decreasing trend (AAPC=-0.783%, P<0.05), and the standardized DALY rates showed no significant trend (AAPC=-0.017%, P>0.05). In 2021, the standardized incidence rate, standardized mortality rate and standardized DALY rate of RA were higher in females than in males; from 1990 to 2021, the standardized DALY rates of RA showed a decreasing trend in females (AAPC=-0.200%, P<0.05) and an increasing trend in males (AAPC=0.316%, P<0.05). The crude incidence rates of RA first increased and then decreased with age in 2021, reaching the highest in the age group of 75-<80 years at 34.36/105. Both the crude mortality rates and the crude DALY rates increased with age, reaching the highest in the age group of 95 years and older at 26.72/105 and 285.67/105, respectively. The standardized incidence rates and standardized DALY rates of RA in China in 2021 were lower than those in high SDI regions, while the standardized mortality rate was lower than that in medium-low SDI regions. Conclusions The burden of RA in China from 1990 to 2021 showed an upward trend, and was at a high level compared to different SDI regions. Higher disease burden of RA was seen in females and the elderly.

ObjectiveTo clarify the application value of nutritional scoring in patients with sepsis and explore the impact of the modified Nutritional Risk in Critically Ill （mNUTRIC） score on the in-hospital fatality of sepsis patients in the emergency intensive care unit （EICU）. MethodsA retrospective analysis was conducted on the clinical data and laboratory examination results of 436 sepsis patients treated in the EICU of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2021 to May 2024. The patients were divided into survival group （298 cases） and death group （138 cases） according to whether they died or not during hospital treatment， and then compared the two groups’ data. Logistic multi-factor regression analysis was used to analyze the risk factors for in-hospital death and the ROC curve to evaluate the predictive value of each risk factor for the prognosis of sepsis patients. ResultsThe death group exhibited higher Acute Physiology and Chronic Health EvaluationⅡ（APACHE Ⅱ） score， Nutritional Risk Screening 2002 （NRS 2002） score， mNUTRIC score， Sequential Organ Failure Assessment （SOFA） score， Padua Prediction Score for Venous Thromboembolism， the proportions of chronic kidney failure and pneumonia patients， C-reactive protein （CRP） level， lactate concentration and neutrophil count， but lower prognostic nutritional index， cholinesterase level， cholinesterase-albumin ratio and lymphocyte count than the survival group， with statistical significance （all P<0.05）. Logistic regression analysis revealed that the mNUTRIC score ［OR=1.254， 95%CI （1.109，1.417）］， CRP ［OR=1.004， 95%CI （1，1.007）］， and pneumonia ［OR=1.82， 95%CI （1.017， 3.257）］ were independent risk factors for in-hospital death in sepsis patients. ROC curve analysis showed that the area under the curve （AUC） of the mNUTRIC score for predicting in-hospital death in sepsis patients was 0.683 ［95%CI （0.623，0.742）］， with a sensitivity of 83% and a specificity of 49.3%. The AUC for CRP and pneumonia were 0.602 ［95%CI （0.533， 0.671）］， and 0.582 ［95%CI （0.516，0.647）］. ConclusionThe mNUTRIC score is an independent predictive indicator for in-hospital death in sepsis patients in the EICU.

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.

Objective:To assess the association of cytotoxic T lymphocyte-associated antigen-4 ( CTLA-4) gene polymorphisms with the prognosis of patients with Bladder urothelial carcinoma (BUC). Methods:From February 2019 to October 2020, 256 BUS patients treated at the Xinxiang Central Hospital were selected as the study group, whilst 250 healthy individuals were selected as the control group. Genotypes of rs5742909 (-318C/T), rs231775 (+ 49A/G) and rs4553808 (-1661A/G) were determined by PCR-restriction fragment length polymorphism assay. The frequencies of genotypes and alleles of the CTLA-4 gene were compared between the two groups. All patients had undergone surgical treatment and were followed up for 3 years and divided into good prognosis group ( n=166) and poor prognosis group ( n=86) based on the status of disease. The distribution of alleles and genotypes were compared, and Kaplan-Meier analysis was used to assess the association of genetic polymorphisms with the prognosis. Results:No significant difference was found in the gender, age, BMI, smoking history and alcohol use between the two groups ( P>0.05). The frequencies of GG genotype and G allele for the rs231775 (+ 49A/G) and rs4553808 (-1661A/G) loci were significantly higher in the study group compared with the control group ( P<0.05), whilst no statistical difference was found in the genotypic and allelic frequency for the rs5742909 locus between the two groups ( P>0.05). Among the 252 subjects who had completed follow-up, 86 had poor prognosis and 166 had good prognosis. The frequencies of GG genotype and G allele at the rs231775 (+ 49A/G) and rs4553808 (-1661A/G) loci were significantly lower in the good prognosis group compared with the poor prognosis group ( P<0.05). Kaplan-Meier survival curve analysis showed that the survival time of patients with GG genotype for the rs231775 (+ 49A/G) and rs4553808 (-1661A/G) loci was significantly shorter than patients with AA or AG genotypes (Log Rank 2 = 13.654, 9.974, P<0.001). Conclusion:The polymorphisms of the rs231775 and rs4553808 loci of the CTLA-4 gene are associated with genetic susceptibility and poor prognosis for BUC, and a higher GG genotypic frequency may increase the risk for infection and poor prognosis of the patients.

Objective To investigate whether modification with IL-21 and CCL19 enhances killing and tumor-infiltrating efficiency of NKP30 CAR-T cells in lung cancer.Methods The modified IL-21-CCL19 NKP30 CAR-T cells expressing IL-21 and CCL19 fusion gene was constructed based on NKP30 CAR-T cells and stimulated with CD3CD28 antibodies and IL-2.The immunophenotype and migration of the cells in the presence of IL-21 were investigated using flow cytometry and migration experiments.Lactate dehydrogenase(LDH)release and sphere formation assays were used to assess the killing and infiltration capabilities of CAR-T cells,and the secretion levels of IFN-γ,IL-21 and CCL19 were determined with enzyme-linked immunospot assay(ELISPOT)and ELISA.A zebrafish model bearing HCG-27 cell xenograft was established by microinjection of the tumor cells into the yolk sac followed 24 h later by injection of the immune cells at the same site,and the fluorescence signals were captured using a fluorescent microscopy.Results The NKP30 ligand B7H6,which was almost undetectable in normal tissues and blood cells,was highly expressed(over 90%)in lung cancer cells.Compared with NKP30 CAR-T cells and conventional T cells,IL-21-CCL19 NKP30 CAR-T cells exhibited stronger proliferative and migration capabilities with the formation of central memory T cells.The reduced expressions of CTLA4 and PD1 in the constructed cells resulted in enhanced killing efficiency against lung cancer cells accompanied by significantly increased production of IFN-γ,IL-21 and CCL19.In the zebrafish models,CAR-T cells exhibited stronger cytotoxicity and proliferative abilities than typical T cells,but these differences were not statistically significant between the two CAR-T cells.Conclusion Modification of NKP30 CAR-T cells with IL-21 and CCL19 facilitates their access into solid tumors for more effective tumor cell killing while producing a large number of memory T cells.

Objective:To investigate the value of implantable cardiac monitor (ICM) in the diagnosis and treatment of patients over 60 years old with unexplained syncope.Methods:This was a multi-center, prospective cohort study. Between June 2018 and April 2021, patients over the age of 60 with unexplained syncope at Beijing Hospital, Fuwai Hospital, Beijing Anzhen Hospital and Puren Hospital were enrolled. Patients were divided into 2 groups based on their decision to receive ICM implantation (implantation group and conventional follow-up group). The endpoint was the recurrence of syncope and cardiogenic syncope as determined by positive cardiac arrhythmia events recorded at the ICM or diagnosed during routine follow-up. Kaplan‐Meier survival analysis was used to compare the differences of cumulative diagnostic rate between the 2 groups. A multivariate Cox regression analysis was performed to determine independent predictors of diagnosis of cardiogenic syncope in patients with unexplained syncope.Results:A total of 198 patients with unexplained syncope, aged (72.9±8.25) years, were followed for 558.0 (296.0,877.0) d, including 98 males (49.5%). There were 100 (50.5%) patients in the implantation group and 98 (49.5%) in the conventional follow-up group. Compared with conventional follow-up group, patients in the implantation group were older, more likely to have comorbidities, had a higher proportion of first degree atrioventricular block indicated by baseline electrocardiogram, and had a lower body mass index (all P<0.05). During the follow-up period, positive cardiac arrhythmia events were recorded in 58 (58.0%) patients in the ICM group. The diagnosis rate (42.0% (42/100) vs. 4.1% (4/98), P<0.001) and the intervention rate (37.0% (37/100) vs. 2.0% (2/98), P<0.001) of cardiogenic syncope in the implantation group were higher than those in the conventional follow-up group (all P<0.001). Kaplan-Meier survival analysis showed that the cumulative diagnostic rate of cardiogenic syncope was significantly higher in the implantation group than in the traditional follow-up group ( HR=11.66, 95% CI 6.49-20.98, log-rank P<0.001). Multivariate analysis indicated that ICM implantation, previous atrial fibrillation, diabetes mellitus or first degree atrioventricular block in baseline electrocardiogram were independent predictors for cardiogenic syncope (all P<0.05). Conclusions:ICM implantation improves the diagnosis and intervention rates in patients with unexplained syncope, and increases diagnostic efficiency in patients with unexplained syncope.

Objective:To investigate the application of (4R)-4-(3-[ 18F]fluoranyl-5-fluorophenyl)-1-((3-methylpyridin-4-yl)methyl)pyrrolidin-2-one( 18F-SynVesT-1), a synaptic vesicle glycoprotein 2A (SV2A) radioactive tracer, in patients with Alzheimer′s disease (AD). Methods:A total of 20 AD patients (2 males, 18 females, age (66.4±8.1) years) with positive β-amyloid (Aβ) deposition and 20 normal controls (NC; 9 males, 11 females, age (62.6±8.6) years ) without Aβ deposition were retrospectively recruited from Huashan Hospital, Fudan University between December 2021 and December 2022. All of them underwent 18F-SynVesT-1 PET/MR and 18F-Florbetapir (AV45) PET/CT scans. Preprocessing of brain 18F-SynVesT-1 PET images was carried out using statistical parametric mapping (SPM). The differences of the uptke of 18F-SynVesT-1 (synaptic density) between two groups based on ROI were compared by using either the independent-sample t test or Mann-Whitney U test. Spearman rank correlation analysis was performed to assess the relationship between synaptic density and cognitive performance. For voxelwise analysis, a general linear model was constructed to analyze differences in synaptic density between the two groups using the independent-sample t test. Furthermore, a multiple linear regression model was developed to explore the relationship between synaptic density and cognitive performance. Results:Compared to the NC group, the AD group exhibited significant widespread reduction in synaptic density across the cortical regions ( P<0.05, false discovery rate (FDR)-corrected), particularly in the medial temporal lobe (0.84±0.09 vs 1.04±0.09; t=-6.95, P<0.001), lateral temporal lobe (1.15±0.13 vs 1.31±0.08; t=-4.56, P<0.001), and lateral parietal lobe (1.24(1.04, 1.26) vs 1.32(1.23, 1.39); z=-3.25, P=0.001). Moreover, synaptic density in extensive cortical regions showed a positive correlation with mini-mental state examination (MMSE) and Montreal cognitive assessment-basic (MoCA-B) scores ( P<0.05, FDR-corrected). Notably, significant associations were observed between MMSE and MoCA-B scores and synaptic density in the lateral temporal lobe ( rs values: 0.71, 0.74, both P<0.001) and medial temporal lobe ( rs values: 0.71, 0.74, both P<0.001). Conclusions:18F-SynVesT-1 PET imaging is a valuable tool for evaluating synaptic density, specifically in the context of AD. The observed widespread reduction in synaptic density across cortical regions of patients with AD are closely related to cognitive decline.

Objective:To identify the risk factors for poor prognosis following interventional treatment in the patients with postherpetic neuralgia (PHN) and construct a predictive model.Methods:The medical records from patients with PHN undergoing interventional therapy at the First Affiliated Hospital of Soochow University from March 2020 to August 2023 were retrospectively collected, including basic characteristics, past medical and surgical history, symptoms, medication therapy, clinical pain score, neutrophil/lymphocyte ratio (NLR) before interventional treatment and interventional treatment methods. Logistic regression analysis was used to identify the risk factors associated with poor prognosis following interventional treatment in PHN patients, and a nomogram predictive model for poor prognosis was constructed. The discrimination and calibration of the nomogram predictive model were evaluated using the C-index and Hosmer-Lemeshow test. Calibration curves and clinical decision curves were drawn to further verify the accuracy of the predictive model.Results:The results of the multivariate logistic regression analysis show that increasing age, prolonged disease duration, elevated NLR, use of immunosuppressants and use of pulsed radiofrequency were independent risk factors for poor prognosis following intervention treatment in PHN patients ( P<0.05). The nomogram predictive model for poor prognosis following PHN interventional treatment constructed based on these factors had a C-index of 0.844. Calibration curves showed good consistency between predicted probability of poor prognosis and actual incidence of poor prognosis. Clinical decision curves indicated that the predictive model provided good accuracy and net benefit. Conclusions:Increasing age, prolonged disease course, elevated NLR, use of immunosuppressants and use of pulsed radiofrequency are independent risk factors for poor prognosis following interventional treatment in the patients with PHN. The nomogram predictive model based on these factors can effectively predict the occurrence of poor prognosis in PHN patients undergoing interventional treatment.

Objective To observe the effects of different surgical approaches on the complications and tumor markers of patients undergoing radical resection of esophageal cancer.Method A prospective study was conducted on 100 patients with esophageal cancer who underwent radical surgery in our hospital from October 2019 to October 2022.They were randomly divided into an observation group and a control group using a random number table method,with 50 patients in each group,he right thoracic approach was used in the observation group and the left thoracic approach was used in the control group.Perioperative indexes,inflammatory factors[Substance P(SP),hypersensitive C-reactive protein(hs-CRP),interleukin6(IL-6)],tumor markers[cytokeratin 19 fragment antigen(CYFRA21-1),squamous cell carcinoma antigen(SCC-Ag)and carbohydrate antigen 199(CA199)]and lung function of the two groups were compared before and after surgery Indicators[vital capacity(VC),forced vital capacity(FVC),and forced expiratory volume in the first second(FEV1)]and complication rate.Result The operating time,blood loss,indwelling time,hospitalization time,and number of lymph node dissection in the observation group were(247.65±27.33)minutes,(211.82±25.49)ml,(6.97±2.12)days,(16.11±3.81)days,and(19.67±5.21),respectively,which were higher than those in the control group[(217.63±23.69)minutes,(175.67±22.13)ml,(5.43±1.80)days,(12.68±3.24)days,(15.45±4.12)](P＜0.05).On average,there was a significant increase in SP,hs CRP,and IL-6 levels in both groups 3 days after surgery(P＜0.05).The levels of SP,hs CRP,and IL-6 in the observation group were(273.96±35.45)ng/L,(11.35±2.12)mg/L,and(8.19±1.67)p.g/ml,respectively,which were lower than the control group[(298.33±38.42)ng/L,(14.29±2.68)mg/L,(10.35±1.82)pg/ml](P＜0.05);One month after surgery,there was a significant decrease in CYFRA21-1,SCC-Ag,and CA199 in both groups(P＜0.05),and in the observation group,the data of CYFRA21-1,SCC-Ag,and CA199 were(2.59±0.37)μg/L,(45.62±6.18)pg/L and(59.37±6.12)U/ml,respectively,which were lower than those in the control group[(3.12±0.43)μg/L,(60.27±7.35)pig/L,(63.28±6.49)U/ml](P＜0.05);One month after surgery,there was a significant decrease in VC,FVC,and FEV1 in both groups(P＜0.05).However,the VC,FVC,and FEV1 in the observation group were(67.21±8.69)％,(70.33±9.41)％,and(72.88±10.12)％,respectively,which were higher than those in the control group[(54.35±8.27)％,(61.65±8.79)％,(65.37±9.24)％](P＜0.05).There was no significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion Both approaches can effectively treat esophageal cancer.Among them,the right chest approach can significantly improve the effect of lymph node dissection,inhibit inflammatory reactions,reduce tumor marker levels,and have less impact on lung function,without significantly increasing the risk of complications.However,the surgical time,bleeding volume,and postoperative recovery time are relatively long.Therefore,a suitable approach should be selected in clinical practice based on the patient's actual situation.
