OBJECTIVE: To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS). METHODS: The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up. RESULTS: All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied. CONCLUSION The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

OBJECTIVES: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. METHODS: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling. The changes in body weight, disease activity index (DAI), colon length, spleen weight, and colon histological scores of the mice were examined, and the percentages of Th17 and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen were analyzed using flow cytometry. The expressions of tight junction proteins (Occludin and ZO-1), proteins associated with inflammasome activation (caspase-1 and p20), IL-1β and TNF-α in the colon tissues were detected using Western blotting or ELISA. In the cell experiment, mouse bone marrow-derived macrophages (BMDMs) primed with lipopolysaccharide (LPS) were treated with DMQ, followed by stmulation with nigericin to activate the classical NLRP3 inflammasome pathway. In cultured human peripheral blood mononuclear cells (PBMCs) treated with either LPS alone or LPS plus nigericin, the effects of DMQ on inflammasome activation, pyroptosis, and cytokine release were evaluated via Western blotting, ELISA, and flow cytometry. RESULTS: In DSS-treated mice, DMQ treatment significantly alleviated DSS-induced body weight loss, colon shortening, spleen enlargement, and colon inflammation. The DMQ-treated mice showed significantly reduced percentages of Th17 cells and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen, with increased occludin and ZO-1 expressions and decreased caspase-1 expression in the colon tissue. DMQ obviously inhibited classical NLRP3 inflammasome activation in mouse BMDMs and both the classical and alternative pathways of NLRP3 activation in human PBMCs, causing also suppression of caspase-1-dependent pyroptosis. CONCLUSIONS DMQ ameliorates DSS-induced UC in mice by inhibiting NLRP3 inflammasome activation.

Objective To explore the value of dual factor combined detection using tuberculosis(TB)specific cy-tokines interferon-γ(IFN-γ)and interleukin-2(IL-2)in TB diagnosis in patients with human immunodeficiency vi-rus(HIV)infection,and the influencing factors for underdiagnosis.Methods HIV-infected patients admitted to and underwent TB-related examination in the Department of Infectious Diseases in Hezhou People's Hospital from July 2022 to September 2024 were collected.According to the clinical diagnosis criteria,patients were divided into the HIV infection with TB group(HIV/TB group)and the HIV infection without TB group(control group).Diag-nostic efficacy of dual factor combined detection was evaluated.HIV/TB group was further divided into a true-posi-tive group and a false-negative group based on the detection results.The independent influencing factors for underdia-gnosis was analyzed using multivariate logistic regression.Results A total of 306 patients were included in the analysis,with an average age of(55.69±14.02)years.There were 105 patients in the HIV/TB group and 201 in the control group.The sensitivity and specificity of dual factor combined detection for TB in all HIV-infected pa-tients were 72.4％(76/105)and 87.1％(175/201),respectively.There was a statistically significant difference in sensitivity(x2=9.488,P=0.009)and no statistically significant difference in specificity(x2=5.846,P=0.054)among the three CD4+T lymphocyte count gradients in the dual factor detection.Among them,patients with CD4+T cell count＜100 cells/μL had lower sensitivity(58.8％)in dual factor detection than patients with CD4+T cell count ≥200 cells/μL(88.9％)and 100-199 cells/μL(81.5％),differences were both statistically significant(both P＜0.05).In HIV/TB co-infected patients with CD4+T lymphocyte count ≥100 cells/μL,the general sensi-tivity and the specificity of dual factor combined detection were 85.2％(46/54)and 82.0％(91/111),respectively.Multivariate analysis showed that CD4+T lymphocyte count was an independent influencing factor for the underdia-gnosis in HIV/TB patients conducting dual factor combined detection(P＜0.05),while age,gender,pathogen re-sults,and the presence or absence of TB had no statistically significant impact on the results of dual factor combined detection(all P＞0.05).Conclusion Dual factor combined detection using tuberculosis-specific cytokines IFN-γand IL-2 has a high diagnostic value in the diagnosis of TB in HIV-infected patients,especially in those with CD4+T lymphocyte count ≥100/μL,which can provide auxiliary diagnostic value for the clinical diagnosis of HIV infection combined with TB.

This report described a periviable extremely preterm infant who received Nirsevimab before discharge for preventing respiratory syncytial virus infection. The infant was born at 22?3 weeks' gestation with a birth weight of 360 g. Nirsevimab was administered on January 12, 2025 (110 days after birth, corrected gestational age of 38?2 weeks) at the Women and Children's Medical Center of Southern Medical University (Shenzhen Maternity & Child Healthcare Hospital). No local or systemic adverse reactions were observed following administration. Follow-up until 1 year and 2 months of age (November 2025) revealed no occurrence of respiratory syncytial virus infection.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

AIM: To screen the predictors of disease progression risk in patients with diabetic macular edema(DME), establish a joint prediction model and analyze its predictive efficiency.METHODS:A retrospective selection was made of 240 patients with DME who were treated in our hospital from July 2021 to October 2024 as the research subjects. The patients were divided into a low-risk group(n=102)and a high-risk group(n=138)based on the central macular thickness(CMT)and whether the fovea was accumulated. The basic information of the patients and relevant examination data such as glycolipid metabolism indicators and liver and kidney function indicators were collected. The indicators with differences in the univariate analysis(P<0.05)were included in the multivariate analysis to screen out the independent influencing factors of disease progression in DME patients and construct a predictive model. The fitting effect of the prediction model was evaluated by the area under the receiver operating characteristic curve, and the prediction model was verified by sensitivity, specificity and Youden index.RESULTS: The general data of the two groups of patients are comparable, and there was no statistically significant difference in blood pressure between the two groups of patients(both P>0.05). Univariate analysis showed that the glycated hemoglobin(HbA1c), fasting blood glucose(FBG), advanced glycation end products(AGEs), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), triglycerides(TG), serum creatinine(Scr), uric acid(UA), and cystatin C(Cys-C)at 3 and 6 mo in the high-risk group at baseline, 3 and 6 mo were higher than those in the low-risk group(all P<0.01). The baseline, 3 and 6 mo estimated glomerular filtration rate(eGFR), total bilirubin(TBIL), and 3 and 6 mo high-density lipoprotein cholesterol(HDL-C)in the high-risk group were all lower than those in the low-risk group(P<0.05). Regression analysis showed that baseline HbA1c, 3 mo FBG, 3 mo AGEs, baseline LDL-C, 3 mo TG, 3 mo eGFR, baseline TBIL, and 6 mo TBIL were risk factors for disease progression in DME patients. The area under curve(AUC)of the combined prediction model was 0.909(95%CI: 0.872-0.945), with a sensitivity of 79.00% and a specificity of 94.10%.CONCLUSION: HbA1c, FBG, AGEs, LDL-C, TG, eGFR and TBIL are risk factors for the risk of disease progression in patients with DME. The combined prediction model can provide a reference for predicting the risk of disease progression in patients with DME.

A 43-year-old male patient presented with recurrent edema in different anatomical sites for over 10 years, with facial edema worsening 1 day prior to admission. He had been repeatedly admitted to dermatology, general surgery, and emergency departments of external hospitals due to " acute abdomen" and " laryngeal edema, " resistant to antihistamines and glucocorticoid therapy. Physical examination revealed non-pitting swelling of the right upper eyelid, bilateral cheeks, and lips asymmetrically. On the night of admission, he developed acute laryngeal edema with dyspnea, which was promptly treated, leading to clinical stabilization. Laboratory screening during the attack revealed decreased serum complement C4 levels, along with reduced functional activity and concentration of C1 esterase inhibitor, confirming a diagnosis of type 1 hereditary angioedema. The patient received lanadelumab for prophylaxis and achieved satisfactory clinical outcomes. He remains under long-term follow-up.

Objective To investigate the effect of extracellular heat shock protein(HSP)22 on Toll-like receptor(TLR)4/nuclear factor-κB(NF-κB)signaling pathway in oxidative-low-density lipoprotein(ox-LDL)-induced inflammatory damage in coronary endothelial cells(HCAECs).Methods HCAECs were cul-tured in vitro and pretreated with ox-LDL to establish a model of high-lipid-induced endothelial cell injury.Re-combinant human HSP22(rhHSP22)was exogenously treated.The effects of rhHSP22 on the expression of inflammation-related proteins such as interleukin(IL)-8,vascular cell adhesion molecule(VCAM)-1 and NF-κB in endothelial cells and endothelial cell apoptosis were observed.The relationship between HSP22 and TLR4/NF-κB signaling pathway was investigated under the action of TLR4 inhibitor E5564.Western blot was used to detect the expression of IL-8,VACM-1 and NF-κB proteins,and flow cytometry was used to detect the apoptosis of endothelial cells in each group.Results Compared with the CNT group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22 group,rhHSP22+ox-LDL group,rhHSP22+E5564 group and rhHSP22+E5564+ox-LDL group were significantly increased,and the differences were sta-tistically significant(P<0.05).Compared with the rhHSP22 group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22+ox-LDL group were significantly increased,and the differences were statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the relative expression levels of IL-8 and VACM-1 in the rhHSP22+E5564+ox-LDL group were decreased,and the differences were statistically significant(P<0.05).Compared with the CNT group,the apoptosis rate in the rhHSP22 group,rhHSP22+ox-LDL group and rhHSP22+E5564+ox-LDL group was significantly increased,and the differ-ence was statistically significant(P<0.05).Compared with the rhHSP22 group,the apoptosis rate in the rhHSP22+ox-LDL group was increased,and the difference was statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the apoptosis rate in the rhHSP22+E5564+ox-LDL group was de-creased,and the difference was statistically significant(P<0.05).Conclusion In ox-LDL-induced inflamma-tory damage of HCAECs,extracellular HSP22 induces the expression of IL-8,VACM-1 and NF-κB proteins by activating the TLR4/NF-κB signaling pathway,and promotes endothelial cell apoptosis.

Objective To explore the incidence rate and independent risk factors of synchronous multiple early gastric cancer (SMEGC) in patients with early gastric cancer, and to provide evidence for early screening and intervention of high-risk population. Methods A retrospective analysis was performed on 308 patients with early gastric cancer who received treatment in the hospital from March 2019 to March 2024. The incidence rate of SMEGC was counted, and the risk factors were analyzed by univariate and multivariate Logistic regression analyses. Results Among the 308 patients with early gastric cancer in this study, 23 cases were SMEGC and 285 were single early gastric cancer, which were included in the SMEGC group and the single group respectively. The incidence rate of SMEGC was 7.47% (23/308). Compared with the single group, the proportions of male, smoking history, tumor diameter≤2 mm, chronic atrophic gastritis and intestinal metaplasia degree were higher in the SMEGC group (2=4.331、8.608、4.618、6.490、4.897，P=0.037、0.003、0.032、0.001、0.027). Logistic regression analysis suggested that chronic atrophic gastritis (OR=3.133, 95%CI: 1.240-7.918) and moderate-to-severe intestinal metaplasia (OR=3.171, 95%CI: 1.252-8.029) were independent risk factors for SMEGC (P<0.05). Conclusion Some patients with early gastric cancer are SMEGC. Chronic atrophic gastritis and moderate-to-severe intestinal metaplasia are independent risk factors affecting the occurrence of SMEGC. It is recommended to regularly screen high-risk patients and optimize management strategies to reduce the risk of SMEGC.
