Objective To observe the value of conventional MRI and diffusion weighted imaging(DWI)for differentiating soft tissue lymphoma(STL)and soft tissue sarcoma(STS).Methods Conventional MRI and DWI data of 25 cases of STL(STL group)and 38 cases of STS(STS group)were retrospectively analyzed.MRI features being statistically different between groups were included in logistic regression analysis to screen the independent risk factors of STL and to evaluate the sensitivity,specificity and accuracy of their combination for predicting STL.Receiver operating characteristic curve was generated,the area under the curve(AUC)was calculated to assess the diagnostic efficacy of the mean apparent diffusion coefficient(ADCmean),the minimum apparent diffusion coefficient(ADCmin),the maximum apparent diffusion coefficient(ADCmax)values for distinguishing STL from STS.Results Slightly hyperintensity on T1WI,non-necrosis,involvement of multiple muscle groups and homogeneous enhancement were all independent risk factors of STL(all P＜0.05).The sensitivity,specificity and accuracy of their combination for predicting STL was 72.00％(18/25),89.47％(34/38)and 82.54％(52/63),respectively.ADCmean,ADCmin and ADCmax values of STL was(1.06±0.18)× 10-3,(0.77±0.14)×10-3 and(1.47±0.31)× 10-3mm2/s,respectively,all lower than those of STS([1.31±0.17]× 10-3,[1.02±0.23]× 10-3 and[1.64±0.16]× 10-3 mm2/s;t=-4.829--2.498,all P＜0.05).The AUC of ADCmean,ADCmin and ADCmax values and their combination for differential diagnosis of STL and STS was 0.845,0.844,0.683 and 0.877,respectively.Conclusion Conventional MRI features,including T1WI signal intensity,necrosis,involvement of multiple muscle groups and enhancement pattern,along with ADCmean and ADCmin values derived from DWI contributed to differentiating STL and STS.

Objective:To investigate the methodological differences in the detection, the inflammatory markers and the pathogenic epidemiological characteristics of influenza A virus in clinical laboratories, in order to provide more diagnostic and epidemiological data for diagnosis and prevention for children with influenza A.Methods:A retrospective cross-sectional study was conducted to collect 96 731 patients with suspected influenza A from January 2016 to October 2024 in Nanyang City Center Hospital from the Clinical Laboratory Testing Information System, including 5 731 patients with confirmed influenza A, aged 5.2 (2.8, 43.7) years old. We analyzed the distribution of influenza A patients from age and mixed infections, the relationship between patient age and positive detection rate by restricted cubic spline (RCS), analyzed differences in testing methods used Kappa consistency testing and receiver operating characteristic (ROC) curves, established a model of inflammatory markers by logistic regression, as well as developed a prediction model and also the mutation of the hemagglutinin (HA) sequence of the influenza A subtype H3N2 virus using evolutionary tree analysis.Results:RCS analysis showed an inverted 'S' shaped non-linear relationship between the positive detection rate of influenza A and the age groups of the patients. Among the mixed infections, 1.43%(1 352/94 867) of the cases were combined with Mycoplasma pneumoniae infection. The Kappa values of reverse transcription PCR (RT-PCR) and serological indirect immunofluorescence assay (IFA) for detecting influenza A in nasopharyngeal swabs and alveolar lavage fluid in clinical laboratories were 0.632 and 0.809, respectively, and those of magnetic particle chemiluminescence assay were 0.614 and 0.668, respectively, and the area under curves in ROC curve of IFA and RT-PCR were 0.869 and 0.792, respectively. The inflammatory indexes were usually elevated in severe children compared with mild children. By binary logistic regression model analysis, neutrophil-to-lymphocyte ratio, D-dimer/fibrinogen and prognosis nutrition index were the risk factors and serum amyloid A/C reactive protein ratio was the protective factor for severe children with influenza A, and the OR values of the above factors were 1.760, 7.076, 1.045, and 0.719, respectively, and P<0.01. By the Bayesian Interdiction Criterion, the optimal seasonal autoregressive moving average mixed model for influenza A epidemics was ARIMA (1, 1, 1) (2, 1, 2) 12 with the highest prediction accuracy of 98.63%. The seven strains of H3N2 all belonged to the same isoforms, with nucleotide similarity of the HA gene ranging from 99.5% to 99.9%, and the glycosylation site, receptor-binding site, and the conserved amino acid residue Glycosylation sites, receptor binding sites and conserved amino acid residues remained unchanged. HA sequence analysis showed that the prevalent strains in Nanyang had undergone mutation to different degree compared with the vaccine strains. Conclusion:Scientific and rational testing and characteristic inflammatory markers in the clinical laboratory are of great clinical value in the diagnosis of children with severe influenza A. At the same time, the epidemiological monitoring of influenza A variants should be strengthened.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Aim To investigate the intestinal protection and possible mechanism of magnolol(MG)in newborn rats with necrotizing enterocolitis(NEC).Methods The rats were randomly divided into control group(Ctrl group),model group(NEC group)and treatment group(MG group).The NEC model was induced by hypoxia,cold stimulation,deep formula milk and LPS intragastric administration in 7-day-old rats for four days.They were killed after five days of treatment with MG(20 mg·kg-1).HE staining was used to observe the intestinal pathological injury.Western blot was used to detect the expressions of IL-1 β,TNF-α,NL-RP3,ASC,caspase-1 and tight junction protein in the distal ileum of rats.Colon contents were collected for 16S rDNA sequencing to understand the gut microbio-ta.Results MG improved the body mass and intesti-nal injury of NEC neonatal rats.The expressions of in-testinal IL-1β,TNF-α,NLRP3,ASC and caspase-1 proteins were down-regulated,and the expressions of Claudin,Occludin and ZO-1 proteins were up-regula-ted.16S rDNA showed that MG increased the diversity of intestinal flora,and at the phylum level,MG in-creased the abundance of firmicutes and bacteroides in NEC model,and decreased the abundance of pro-teobacteria.At the genus level,MG treatment in-creased the abundance of Lactobacillus,unclassified_Muribaculaceae,Racteroides,but decreased the abun-dance of Escherichia_Shigella,Rodentibacter and Fuso-bacterium.Conclusion MG intervention can protect the intestinal tract of NEC rats by potentially improving barrier function,and regulating the intestinal microbiota through the NLRP3/ASC/caspase-1 signaling pathway.

Objective:To screen inflammatory markers that can be used for the diagnosis and intervention evaluation of patients with chronic kidney disease(CKD)with depression,and to systematically study the therapeutic effect and safety of modified Chaihu Longgu Muli decoction in patients with CKD with depression.Methods:This study was a prospective study,a total of 120 patients with CKD who were diagnosed and treated in the Department of Nephrology,Chongqing Traditional Chinese Medicine Hospital from April 2023 to October 2024 were included.They were divided into CKD with depression(CKD-D)group and CKD without depression(CKD-N)group according to the diagnostic criteria by random number table method.The results of routine laboratory tests were collected,and the severity of depressive disorder was evaluated by Hamilton Depression Rating Scale-17(HAMD-17).The levels of interleukin-18(IL-18),interferon-γ(IFN-γ),β-thromboglobulin(β-TG),platlet factor-4(PF-4),eosinophil chemotactic factor(Eotaxin),soluble tumor necrosis factor receptor-2(sTNFR-2)and CD40 ligand(CD40L)in serum were quantitatively evaluated by liquid chip technology.Pearson correlation analysis was used to analyze the correlation between HAMD-17 scores and inflammatory markers with statistical differences in CKD patients with depression at different stages.The patients in CKD-D group were randomly divided into control group and treatment group.The control group was given basic treatment of CKD,while the treatment group was treated with modified Chaihu Longgu Muli decoction on the basis of the control group.After 8 weeks of continuous intervention,the clinical effective rate,the changes of effective inflammatory markers and the occurrence of adverse reactions were compared between the two groups.Results:In the CKD-D group and the CKD-N group,the difference of HAMD-17 score,serum phosphorus(P),serum creatinine(Scr),estimated glomerular filtration rate(eGFR),albumin(ALB),serum iron(Fe3+),C-reactive protein(CRP),IL-18,IFN-γ,sTNFR-2 indicators were statistically significant(P＜0.05).Multivariate Logistic regression analysis showed that in addition to HAMD-17 score(OR=1.259,P=0.006),SCr(OR=1.748,P=0.003),eGFR(OR=1.354,P=0.005),serum IL-18(OR=0.924,P=0.011)and IFN-γ(OR=0.859,P=0.031)levels were also independent influencing factors for CKD patients with depression.Pearson correlation analysis showed that there was a significant positive correlation between HAMD-17 score and IL-18,IFN-γ,sTNFR-2 and CD40L.The total clinical effective rate of the treatment group was higher than that of the control group,and the serum levels of IL-18 and IFN-γ in the treatment group were lower than those in the control group,the differences were statistically significant(P＜0.05),and no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:IL-18 and IFN-γ can be used as effective serum markers for the diagnosis and treatment of depressive disorders in CKD patients.At the same time,the changes of serum levels of IL-18 and IFN-γ can be used to evaluate the severity of symptoms in CKD patients with depression at different stages to a certain extent.Modified Chaihu Longgu Muli decoction may improve CKD combined with depressive symptoms and improve the quality of life of patients by down-regulating the level of inflammatory factors.

Objective To screen genes associated with poor prognosis of colorectal cancer(CRC)through bioinformatics analysis.Methods The gene expression profiles of GSE74602,GSE110223,GSE113513 and GSE141174 were obtained from Gene Expression Omnibus(GEO)database,including samples from 65 CRC tissues and 65 normal tissues.Differentially expressed genes(DEGs)between CRC tissues and normal tissues were screened out by GEO2R tool and Venn software,and the consistent genes were extracted from DEGs by Venn software.A protein-protein interaction(PPI)network was constructed by the STRING database to identify key genes,which were analyzed by Kaplan-Meier Plotter and GEPIA.Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis was conducted on the 13 selected genes.Results There were 171 DEGs obtained from the four datasets,including 148 up-regulated genes and 23 down-regulated genes.Up-regulated DEGs were enriched in the redox processes,bicarbonate transport,digestion,ion trans-membrane transport,and one-carbon metabolism;and down-regulated DEGs were enriched in the positive regulation of cell proliferation.The survival curve analysis showed that 30 of the 87 genes were significantly associated with poor survival prognosis.GEPIA showed that 13 of the 30 genes were highly expressed in CRC tissues compared to normal tissues,among which MYC and FGFR3 markedly enriched in the CRC pathway.Conclusion This study identifies that MYC and FGFR3 are significantly up-regulated in CRC and closely associated with poor prognosis,suggesting that they may serve as potential prognostic markers and therapeutic targets for CRC patients.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Graves'ophthalmopathy(GO)is a specific autoimmune disease occurring in orbital tissues and is closely related to hyperthyroidism caused by Graves'disease(GD).Its disabling and disfiguring features significantly impact the quality of life of patients.The exact mechanism of GO still remains to be fully elucidated.In recent years,gene sequencing and medical microbiology studies have shown that changes in the gut microbiota may play a role in the development and progression of GO,with gut dysbiosis altering immune system regulatory signals and causing immune damage to organs.Clarifying the correlation between gut microbiota and GO helps to understand the disease's pathogenic mechanism and provides a theoretical basis for the diagnosis and treatment of GO.This review summarizes the impact of gut microbiota dysbiosis in the pathogenesis of GO and promising therapeutic approaches,including research progress in aspects such as gut microbiota experiments,case studies,pathogenesis,and treatment strategies.

Objective To explore the abnormal expression of the MT-ND family in pan-cancers and its prognostic value.Methods Transcriptome expression and clinical data of 33 cancers were downloaded from the TCGA database,thereby analyzing the expression differences of the MT-ND family in tissuesof different types of cancers and normal tissues.The prognostic role of the MT-ND family in pan-cancers was explored by univariate Cox regression analysis and Kaplan-Meier survival analysis.Results The expression of the MT-ND family was upregulated in the kidney chromophobe,acute myeloid leukemia and thymoma,and downregulated in the remaining tumors.The expression of the MT-ND family was associated with the overall survival rate of different types of cancers.In addition,the MT-ND family were significantly correlated with the immune invasion subtypes,and were correlated with stromal cell invasion and tumor cell stemness to varying degrees.The expression of MT-ND4 was downregulated in brain lower grade glioma,which was a protective factor for prognosis;while the expression of MT-ND4 in thymoma was upregulated,which was a risk factor for prognosis.Conclusion Pan-cancer analysis has confirmed that the MT-ND family can predict the tumor prognosis,which provides new ideas and strategies for the precision treatment and prognostic management of cancer.

Objective:This study aims to analyze historical trends and predict future trends of disability-adjusted life years (DALYs) attributable to high BMI for osteoarthritis (OA) in China. OA is a common chronic degenerative joint disease, with high body mass index (BMI) being a significant risk factor. in China.Methods:Based on the Global Burden of Disease (GBD) 2021 database, we analyzed trends in high-BMI-attributable OA. The ASR of hogh-BMI-attributable OA DALYs increased from DALYs in China from 1990 to 2021. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to assess trend changes of trends. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Chi-square tests were used to compare differences in high BMI attribution proportions between regions and years.Results:From 1990 to 2021, China′s OA DALYs increased from 1.829 to 5.327 million, with the proportion attributable to high BMI rising from 13.47% to 21.86% ( χ2=60 527.25, P<0.001). The ASR of high-BMI-attributable to OA increased from 27.4 (-2.2, 81.5) per 100,000 to 53.0 (-4.7, 150.7) per 100 000, with an EAPC of 2.48% [95% (uncertainty interval, UI): 2.35, 2.62]. In 2021, females showed significantly higher ASR (69.2 per 100 000) than males (36.1 per 100 000). Knee OA (ASR: 50.5/100 000) demonstrated substantially higher burden than hip OA (ASR: 2.5/100 000). Age effect analysis showed DALYs peaked at ages 80~90; period effect indicated accelerated growth after 2005; cohort effect showed a U-shaped trend with the 1990 birth cohort having the highest relative risk (approximately 3.0). Projections indicated that up to 2046, total OA DALYs will reach approximately 2.39 million with an ASR of about 71, showing more significant growth among females (ASR reaching 100). Conclusion:High-BMI-attributable to OA DALYs in China shows a significant upward trend, and is expected to continue. This trend is more pronounced among females and elderly populations than males, highlighting the urgency of implementing preventive measures for high-risk groups, particularly in weight management.
