Objective To understand the status of body image disturbance and its influencing factors in patients with ankylosing spondylitis (AS), so as to provide a scientific basis for the clinical management of AS. Methods A total of 353 AS patients admitted from January 2022 to December 2024 were selected as research subjects. Chinese version of Body Image Disturbance Questionnaire (BIDQ) was used to investigate the body image disturbance in AS patients. Single factor analysis was performed by t test and analysis of variance, and multiple factors were analyzed by multivariate linear regression. Results The total score of BIDQ in 342 AS patients was (25.01±4.22). Multivariate linear regression analysis results showed that self-paid medical expense, nighttime VAS score and negative emotion PANAS score could positively predict body image disturbance in AS patients (standardized regression coefficient=0.413, 0.413, 0.460, P<0.05), and PSSS score, positive emotion PANAS score and exercise management CDSSM score could negatively predict body image disturbance (standardized regression coefficient=-0.245, -0.134, -0.247, P<0.05). Conclusion The body image disturbance in AS patients is worthy of clinical attention. Nighttime pain, negative emotion and self-paid medical treatment can increase the risk of body image disturbance. Positive emotion, social support and high self-management level of exercise behavior can reduce the formation of body image disturbance, which can provide new ideas for clinical management of AS patients.

Objective: To investigate whether Tuina alleviates fibrotic symptoms in myofascial trigger points (MTrPs) by regulating transforming growth factor (TGF)-β1/Smad3 signaling pathway, thereby deactivating these points. Methods: This study comprised two experimental phases. In phase 1, 27 specific pathogen-free (SPF) grade female Sprague-Dawley (SD) rats were randomized into three groups: control 1, model 1, and Tuina 1 groups. Model 1 and Tuina 1 groups underwent an 8-week MTrPs modeling protocol involving blunt impact and eccentric exercise. After successful modeling, rats in Tuina 1 group received manual pressing on nodules or cord-like taut bands on the medial aspect of the left hindlimb. Pain sensitivity and tissue stiffness were evaluated via pressure pain threshold (PPT) and soft tissue tension (STT). Muscle histopathology and fibrosis were observed using hematoxylin and eosin (HE) and Masson staining. Inflammatory factors in muscle were measured by enzyme-linked immunosorbent assay (ELISA), while immunofluorescence (IF) and Western blot (WB) were used to detect the expression levels of α-smooth muscle actin (α-SMA), collagen Ⅲ, and TGF-β1. In phase 2, 45 SPF female SD rats were randomized into five groups: control 2, model 2, Tuina 2, TGF-β1 inhibitor (TI), and Tuina + TGF-β1 agonist (Tuina + TA) groups. All groups except control 2 underwent standardized MTrPs modeling. Rats in Tuina 2 group received consistent pressing manipulation. TI group received intraperitoneal injections of oxymatrine, while Tuina + TA group received intraperitoneal injections of SRI-011381 hydrochloride followed by the same pressing protocol as Tuina 2 group. WB was used to detect the expression of collagen I, collagen III, TGF-β1, and phosphorylated-Smad3 (p-Smad3)/Smad3. Results: In phase 1, Tuina significantly improved PPT and STT in MTrPs of rats (P < 0.01), reversed pathological damages including disorganized muscle fiber arrangement, abnormal myocyte morphology, and exacerbated fibrosis. In addition, in MTrPs of rats in model 1 group, expression levels of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and fibrosis markers (α-SMA, collagen I, and collagen III) were upregulated, and all exhibited a significant downward trend after Tuina intervention (P < 0.05 or P < 0.01). This indicates that the therapeutic effects of Tuina are directly associated with reduced local inflammation and fibrosis in MTrPs. In phase 2, compared with model 2 group, rats in TI and Tuina 2 groups had decreased expression levels of TGF-β1 and p-Smad3/Smad3 in MTrPs, alongside reduced levels of inflammatory factors (IL-1β, IL-6, NF-κB, and TNF-α) and fibrosis markers (α-SMA, collagen I, and collagen III) (P < 0.05 or P < 0.01). When co-administered with TGF-β1 agonist, the therapeutic effects of Tuina were significantly attenuated, with rebounded TGF-β1 expression and p-Smad3/Smad3 in local MTrPs, and fibrosis and inflammatory responses were re-exacerbated (P < 0.05 or P < 0.01). Conclusion Tuina can effectively reduce inflammatory responses and fibrosis in MTrPs tissue, and its mechanism is closely related to the inhibition of the TGF-β1/Smad3 signaling pathway, which plays a critical role in Tuina-mediated regulation of MTrPs fibrosis.

Temporal lobe epilepsy(TLE)is the most common form of focal epilepsy in adults,characterized by spontaneous recurrent seizures,with most patients experiencing drug resistance and cognitive dysfunction.MicroRNAs(miRNAs)play a critical role in the pathological process of TLE through their regulation of post-transcriptional gene expression.The pathogenesis of TLE has not been fully elucidated,lacking effective clinical therapeutic targets and prognostic markers.This review sum-marized the expression changes of miRNAs in TLE and their research progress as potential biomarkers,aiming to provide new insights into the early diagnosis,prognosis evaluation,and pathogenic mecha-nisms of TLE.

OBJECTIVE: To explore the genetic characteristics and pathogenesis for a child with mosaicism trisomy 21 and Congenital leukemia (CL). METHODS: A child who was admitted to Ningbo Women and Children's Hospital in March 2023 was selected as the study subject. A retrospective analysis was carried out on the clinical data, laboratory test results, immunophenotyping, and genetic characteristics of the child. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: EC2024-063). RESULTS: Whole genome sequencing (WGS) revealed that the child has mosaicism trisomy of chromosome 21, with a ratio of approximately 74%. In addition, copy number variations involving multiple OMIM genes that could explain his clinical phenotype were detected and rated as pathogenic based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). No pathogenic variant was detected with the GATA1 gene. Blood immune typing of the child conformed to the immunophenotype of acute myeloid leukemia. CONCLUSION For children with trisomy 21, even in the absence of GATA1 gene variants, the occurrence of CL should be monitored, and early diagnosis and treatment are of great significance for improving the prognosis.

Objective:To investigate the correlation between frailty and falls among older adult residents in communities in Xinjiang Uygur Autonomous Region.Methods:This study is a prospective research. In June 2024, the 1 047 older adults (aged 65 years and older) included in the "A longitudinal cohort study of aged population in Xinjiang" (ChiCTR2400093292) were followed up. The Fried frailty phenotype was used to assess the frailty status of the participants, and general information was collected, including whether the participants had experienced falls in the past 12 months. Multivariate logistic regression analysis was performed to identify the risk factors for falls among older adults in communities in Xinjiang Uygur Autonomous Region.Results:Among the 1 047 participants, the incidence of falls among older adults was 10.2% (107/1 047). There were significant differences in frailty status and age between case and control groups (both P < 0.05). Logistic regression analysis indicated that frailty and increasing age are risk factors for falls among older adults in communities in Xinjiang Uygur Autonomous Region. The more severe the frailty, the greater the risk of falls ( χ2 = 7.57, P < 0.006, OR = 2.509, 95% CI: 1.303-4.830). Similarly, the greater the age, the greater the risk of falls ( χ2=8.94, P = 0.003, OR = 1.030, 95% CI: 1.013-1.064). Conclusions:Falls among older adults in communities in Xinjiang Uygur Autonomous Region are closely associated with frailty. It is essential to improve the assessment and screening of fall risks in frail older adults and to develop effective and appropriate fall prevention measures for this high-risk population.

[Purpose]To analyze cancer incidence and mortality in Liaoning cancer registration areas from 2016 to 2020 and the trends from 2006 to 2020.[Methods]Cancer data in cancer registra-tion areas in Liaoning Province from 2016 to 2020 were collected.The incidence and mortality,age-standardized rate,cumulative rate(0～74 years old),and age-specific rate were calculated.Age-standardized incidence and mortality rate were calculated by the Chinese standard popula-tion(ASIRC,ASMRC)and Segi world standard population(ASIRW,ASMRW).Joinpoint software was applied to analyze the trends of incidence and mortality.[Results]From 2016 to 2020,the crude incidence rate of cancer in Liaoning cancer registration areas was 422.30/105,the ASIRC and ASIRW were 215.67/105 and 209.52/105.The ASIRC was higher in urban areas(225.00/105)than that in rural areas(190.15/105),and higher in male(221.47/105)than that in female(213.03/105).The crude mortality rate was 254.22/105,the ASMRC and ASMRW were 113.26/105 and 112.91/105.The ASMRC in urban areas(113.12/105)was the same as that in rural areas(113.01/105),and higher in male(146.86/105)than that in female(83.46/105).The ASIRW of lung cancer was 46.13/105,and the ASMRW was 32.04/105,both ranking the first of all cancers.From 2006 to 2020,the crude incidence,ASIRC and ASIRW in urban areas showed an increasing trend(AAPC=3.921％,t=16.222,P＜0.05;AAPC=0.823％,t=2.409,P＜0.05;AAPC=0.875％,t=2.933,P＜0.05).The crude incidence,ASIRC and ASIRW in urban female were all rising(AAPC=4.151％,t=15.888,P＜0.05;AAPC=1.597％,t=4.819,P＜0.05;AAPC=1.514％,t=4.752,P＜0.05).During the same period,the cancer mortality in urban areas showed an increasing trend(AAPC=3.175％,t=14.745,P＜0.05),and the ASMRW showed a decreasing trend(AAPC=-0.908％,t=-2.273,P＜0.05).The crude mor-tality of both men and women showed an increasing trend(AAPC=3.010％,t=6.032,P＜0.05;AAPC=2.820％,t=5.921,P＜0.05),while the crude mortality and ASMRW for female showed a significant downward trend(AAPC=-1.487％,t=-2.437,P＜0.05;AAPC=-2.680％,t=-2.246,P＜0.05).From 2016 to 2020,the crude incidence,ASIRC and ASIRW in rural areas showed no significant change;however,the crude incidence in male was increasing(AAPC=2.025％,t=3.853,P＜0.05).In the same period,the crude mortality rate in rural areas increased(AAPC=3.577％,t=9.377,P＜0.05),while there was no significant change in the ASMRC and ASMRW.The crude mortality of both men and women showed an increasing trend(AAPC=3.377％,t=10.615,P＜0.05;AAPC=3.978％,t=7.245,P＜0.05),while there was no significant change in ASMRC and ASMRW.[Conclusion]The cancer burden in Liaoning from 2016 to 2020 was higher than the average level in China,can-cer prevention and control should be further strengthened in the provice.

Objective To investigate the effects of governor vessel pushing manipulation on behavioral outcomes in valproic acid(VPA)-induced autism spectrum disorder(ASD)rats and explore its underlying mechanisms using prefrontal RNA sequencing(RNA-Seq).Methods Nine Sprague-Dawley pregnant rats at gestational day 12.5 were divided into two groups,six received intraperitoneal VPA injection(600 mg/kg)for modeling,and three received saline.Male offspring at postnatal day 21 were evaluated using the three-chamber social test and open field test to validate the ASD model.VPA-induced male offspring were randomly assigned to the model group(n=5)or tuina group(n=5),while saline offspring formed the blank group(n=5).The blank group and model group received no intervention,while the tuina group underwent governor vessel pushing manipulation stimulation along the governor vessel using a custom device,twice a day for 14 days,totaling 28 times.Post-intervention,behavioral assessments included social index(SI)and social preference index(SPI)in the three-chamber test,total distance traveled and central zone time in the open field test,marble-burying test for stereotyped behaviors,and Nissl staining for prefrontal cortical neuron survival.RNA-Seq identified differentially expressed genes(DEGs)in the prefrontal cortex,followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.Real time fluorogenic quantitative PCR(RT-qPCR)validated DEGs,and Western blotting analyzed proteins in enriched pathways.Results Pre-intervention,both model and tuina groups showed reduced SI,SPI,total distance,and central zone time compared to the blank group(P<0.05),confirming successful modeling.Post-intervention,the model group exhibited lower SI,SPI,total distance,central zone time,increased marble-burying(P<0.05),and fewer Nissl bodies(P<0.01)versus the blank group.Compared to the model group,the tuina group displayed improved SI,SPI,total distance,central zone time(P<0.05),reduced marble-burying(P<0.05),and increased Nissl bodies(P<0.01).RNA-Seq revealed 213 prefrontal DEGs(181 upregulated,32 downregulated)in the tuina group.GO analysis highlighted cellular components,while KEGG identified 181 pathways,with 67 significantly enriched(P<0.05),notably the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)pathway.RT-qPCR confirmed decreased collagen type Ⅰ alpha 2(Col1α2),transforming growth factor-α(TGF-α),epidermal growth factor receptor 3(ErbB3),and serum/glucocorticoid regulated kinase 2(Sgk2)(P<0.05),and increased hepatic growth factor(Hgf)(P<0.01)in the model group,reversed by governor vessel pushing manipulation.Western blotting showed reduced prefrontal NRG1,ErbB3,nNOS,PI3K,AKT,p-nNOS,p-PI3K,and p-AKT in the model group(P<0.05),which were upregulated by tuina.Conclusion Governor vessel pushing manipulation ameliorates social deficits,anxiety,stereotyped behaviors,and neuronal loss in ASD rats,potentially via activation of the PI3K/AKT signaling pathway.

Objective To investigate the effect of benserazide combined with respiratory training on post-stroke dysphagia.Methods A total of 120 patients with dysphagia after stroke were prospectively selected and randomly divided into the combination group and the breathing exercise group,with 60 cases in each group.The breathing exercise group was treated with rehabilitation breathing training,and the combination group was treated with dopa serazide on the basis of rehabilitation breathing training,3 times a day,1 tablet once.The traditional Chinese medicine(TCM)syndrome scores,clinical efficacy and swallowing function indexes including dysphagia angiography score(VDS),osmotic-aspiration scale(PAS)score,Lowada drinking water test score and VFSS score were compared between the two groups.Nutritional indices[total cholesterol(TC),triglyceride(TG),albumin(ALB),hemoglobin(Hb)],related indexes of nerve function[nerve function and serum growth differentiation factor 15(GDF-15),central nerve specific protein soluble protein-100β(S100β)],quality of life and anxiety disorder score[Quality of Life Rating Scale(SF-36)score,Generalized Anxiety Disorder Scale(GAD-7)score]and adverse reactions were compared between the two groups.Results The total effective rate of the combination group(91.67%)was obviously increased(P＜0.05)compared to the breathing exercise group(58.33%).Compared with before treatment,after treatment,tongue flaccidity,slow swallowing,choke after drinking water,tongue coating ecchymosis,score of fine pulse,VDS,PAS,score of Lowada drinking water test,GDF-15 level and GAD-7 score were decreased in the two groups,and those of the combination group were significantly lower than the breathing exercise group(P＜0.05).The levels of TC,TG,ALB,Hb,S100β,VFSS and SF-36 were increased in the two groups,and those of the combination group were higher than the breathing exercise group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Benserazide combined with respiratory training has high clinical efficacy in patients with post-stroke dysphagia,which can effectively improve the TCM evidence score and nutritional indicators,improve swallowing function,reduce anxiety,improve quality of life,and have more ideal clinical application.

Objective:To investigate the clinical characteristics and prognostic significance of germline mutations in patients with myelodysplastic neoplasms (MDS) .Methods:Clinical data from 407 patients with MDS [male, 252; female, 155; median age, 64 (range, 19-85) years] diagnosed at the First Affiliated Hospital of Zhejiang University School of Medicine were retrospectively analyzed. The clinical features and prognostic effects of germline mutations were evaluated.Results:The prevalence of germline mutations in patients with MDS was 5.9% (24/407), peaking at 20.0% in the group aged 21-30 years. The spectrum of germline mutations comprised DDX41 (9 cases, 2.2%), TP53 (3 cases, 0.7%), and single cases of RUNX1, TET2, MPL, CBL, ATRX, CEBPA, ETV6, IDH1, KDM5C, SBDS, GNAS, and CTC1. Patients with germline mutations exhibited significantly lower peripheral WBC counts than those without (1.87×10 9/L vs 2.50×10 9/L, P=0.018), but showed comparable median overall survival (21.3 months vs 21.1 months, P=0.97). Patients with DDX41 germline mutations, compared with those with other germline mutations, had a significantly older median age (65 vs 54 years, P=0.010), lower WBC counts (1.51×10 9/L vs 2.31×10 9/L, P=0.040), increased mean corpuscular volume (111.80 fl vs 97.25 fl, P=0.003), and a higher prevalence of normal karyotypes (100.0% vs 53.3%, P=0.022). The most frequently co-occurring somatic mutations in DDX41 germline mutation carriers were ASXL1, TET2, and RUNX1. Conclusion:In this study, the detection rate of germline mutations in MDS patients was 5.9% (24/407), peaking at 20% in the group aged 21-30 years. DDX41 and TP53 were the most prevalent germline mutations. DDX41 mutation carriers displayed distinct clinical characteristics; however, germline mutations overall showed no significant prognostic effect.
