Objective:To investigate the expression of family with sequence similarity 110 member B (FAM110B) and analyze its associations with clinical prognosis, tumor heterogeneity, and immune-related gene expression through a pan-cancer analysis.Methods:TCGA and GTEx databases were used to evaluate the differential expression of FAM110B at mRNA level in pan-cancer and normal tissues. SangerBox platform and TISIDB database were used to analyze the associations of the expression level of FAM110B mRNA with clinical stages, histological grades, and overall survival of patients. The cBioPortal database and the GSCALite platform were used to analyze the genetic variations in the FAM110B gene, and the associations of FAM110B expression with immune regulatory genes, immune checkpoints, tumor mutation burden, microsatellite instability, and anti-cancer drug sensitivity. qRT-qPCR and Western blot were used to detect the expression of FAM110B at mRNA and protein levels in pancreatic cancer, respectively. Independent samples t-test was employed to assess the significance of differences between two groups; Spearman correlation coefficient was used to evaluate the associations between variables; Log-rank test was used for survival analysis. Results:FAM110B was abnormally expressed in a variety of tumors and associated with the overall survival of patients ( P<0.05), with the most significant difference observed in pancreatic cancer ( P<0.001). In vitro experiments verified that FAM110B was highly expressed in PANC-1 cells ( P<0.01), a pancreatic cancer cell line, and its expression level was related to pathological staging and histological grading ( P<0.001). In addition, the expression level of FAM110B mRNA was related to the expression levels of multiple immunomodulatory genes and correlated with tumor mutational burden and microsatellite instability in various tumors ( P<0.05). Conclusions:FAM110B is related to the prognosis, immune regulation, and tumor heterogeneity across multiple cancers, demonstrating promising potential in both basic research and clinical treatment of various cancers.

Background and aims:Studies indicate that the gut microbiota and its metabolites are involved in the progression of cardiovascular diseases,and enterohepatic circulation plays an important role in this progression.This study aims to identify potential probiotics for the treatment of unstable angina(UA)and elucidate their mechanisms of action.Methods:Initially,the gut microbiota from patients with UA and control was analyzed.To directly assess the effects of Bifidobacterium supplementation,10 patients with UA were enrolled and administered Bifidobacterium(630 mg per intake twice a day for 1 month).The fecal metagenome,serum trimethyl-amine N-oxide(TMAO)levels,and other laboratory parameters were evaluated before and after Bifido-bacterium supplementation.Results:After supplementing with Bifidobacterium for 1 month,there were statistically significant dif-ferences(P＜0.05)in TMAO,aspartate aminotransferase,total cholesterol,and low-density lipoprotein compared to before.Additionally,the abundance of Bifidobacterium longum increased significantly,although the overall abundance of Bifidobacterium did not reach statistical significance.The gut micro-biota,metabolites,and gut-liver axis are involved in the progression of UA,and potential mechanisms should be further studied.Conclusions:Metagenomic analysis demonstrated a reduced abundance of Bifidobacterium in patients with UA.Supplementation with Bifidobacterium restored gut dysbiosis and decreased circulating TMAO levels in patients with UA.This study provides evidence that Bifidobacterium may exert cardiovascular-protective effects through the gut-liver-heart axis.

Esophagectomy is an effective treatment for esophageal cancer,and there has been growing attention on the importance of postoperative pain management in patients undergoing the surgery.Epidural analgesia is the preferred analgesic approach for open esophagectomy.With the development of surgical technology,minimally invasive esophagectomy(MIE)has become the mainstream surgical approach.However,no conclusion has been reached concerning whether epidural analgesia is still the preferred analgesic approach for MIE.Herein,we analyzed the relevant literature published in recent years and found that epidural analgesia continued to be an important analgesic approach for MIE,offering the best analgesic effect.Epidural analgesia can reduce postoperative pulmonary complications,improve the quality of life,and reduce the stress response.Adverse effects can be minimized through accurate selection of epidural puncture segments,individualized medication,and multimodal analgesia strategies.In the future,precision-based multimodal analgesia can be achieved using emerging technologies such as big data analytics and artificial intelligence.

Objective:To investigate the clinical effect of chimeric flap with perforating branch of superficial circumflex iliac artery in reconstruction of complex tissue defect in Achilles tendon region.Methods:A retrospective analysis was conducted on 9 patients who underwent reconstruction of composite tissue defects in Achilles tendon region with the perforator flap of lateral femoral circumflex artery, from January 2017 to January 2023 in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University. The patients were 7 males and 2 females and at 16 to 54 years, with 36.6 years in average. Causes of injury were: 5 patients by traffic accident, 2 by machine strangulation and 1 by heavy object, also 1 defect was caused by infection. The soft tissue defects were 4.5 cm×6.0 cm to 8.0 cm×12.0 cm in size, and the defects of Achilles tendon were 4.5 cm to 11.5 cm, with an average of 6.8 cm in length. The wounds were managed with VSD after primary surgery, and then stage Ⅰ surgery were followed to reconstruct the defects in Achilles tendon region with perforator flap of lateral femoral circumflex artery. The sizes of chimeric flaps were 6.5 cm×5.0 cm to 18.0 cm×6.5 cm, including 3 lobuated flaps. The fascia grafts were 5.5 cm to 12.0 cm, with an average of 7.0 cm. Scheduled postoperative follow-ups were conducted in outpatient clinic and via telephone or WeChat interviews, together with the advices for rehabilitation training. Postoperative functions of the Achilles tendon and ankle function were evaluated using Arner-Lindholm criteria and the ankle and hindfoot functional score of American Orthopaedic Foot and Ankle Society (AOFAS).Results:All of the 9 chimeric flaps survived and all the donor sites had primary healing. All patients were entered into the postoperative follow-up for 10 to 66 months, with 14.6 months in average. One chimeric flap was found bulky and a flap thinning surgery was further carried out in 3 months under the request of patient. The rest of patients were satisfied with the appearance and texture of the flaps. The range of ankle plantar flexions was found at 42.9°±1.8° and the dorsal flexions was at 16.2°±2.5°. There was no significant decrease in circumference and no discomfort or muscle re-rupture in the affected legs. Thompson test was found negative. There was no wound related complications during follow-up. Reconstructive surgery were found effective based on Arner-Lindholm criteria, with excellent in 6 patients, good in 2 and 1 in fair. The ankle and subtalar joint function was evaluated according to the ankle-hindfoot function score of AOFAS, with 7 patients scored 90-100 point and 2 scored 75-89 point, and 7 patients were in excellent and 2 in good.Conclusion:The chimeric perforator flap of lateral femoral circumflex artery is safe and reliable in reconstruction of composite tissue defects in Achilles tendon region. It can effectively restore the function and appearance of ankle and hindfoot in patients with composite tissue defects in the Achilles tendon region.

Objective:To explore the clinical application value of infrared thermal imaging in assisting the repair of complex joint tissue defects in children using the lateral femoral circumflex artery (LFCA) chimeric perforator flap.Methods:A retrospective analysis was conducted on clinical data from the Department of Burns and Plastic Surgery at the Affiliated Hospital of Zunyi Medical University between May 2019 and September 2023. The study included cases where the LFCA perforator chimeric flap was used to repair complex joint tissue defects in children. Preoperative perforator mapping was performed using an infrared thermal imaging device combined with a portable Doppler. The flap and fascial flap were designed based on the distribution of hot spots and thermal lines. Intraoperative confirmation of perforator distribution was carried out. Postoperative follow-ups were conducted to assess flap survival, the need for secondary thinning procedures, wound healing status, donor site scarring, joint swelling, and functional recovery.Results:A total of 11 pediatric patients were enrolled, including 8 males and 3 females, aged 2 to 14 years (mean age: 5.8 years). The injury mechanisms included traffic accidents (6 cases), wheel spoke injuries (2 cases), falls (2 cases), and heavy object crush injuries (1 case). Affected joints included the wrist (1 case), knee (2 cases), and ankle (8 cases). Associated injuries included metacarpal fracture (1 case), metatarsal fractures (2 cases), and extensor tendon defects (1 case). Tendon defect length was 3 cm, joint capsule defect area ranged from 2 cm × 3 cm to 4 cm × 6 cm, and fascial flap size ranged from 2 cm × 4 cm to 2 cm × 14 cm. Skin defect area ranged from 5 cm × 3 cm to 16 cm × 9 cm, and flap size ranged from 6 cm × 4 cm to 15 cm × 5 cm. Preoperative infrared thermography identified 28 hot spots, with 26 perforators confirmed intraoperatively (positive rate: 92.9%). Thermal line distribution zones consistently corresponded to perforator branches. All 11 flaps survived, with primary healing achieved at both donor and recipient sites. Follow-up duration ranged from 6 to 36 months (mean: 10.5 months). All recipient sites exhibited soft flap texture. One case required secondary debulking due to flap bulkiness. Donor sites showed only linear scarring. During follow-up, no significant joint swelling, functional impairment, or joint dislocation was observed.Conclusion:Infrared thermal imaging-assisted perforator mapping for the design of LFCA chimeric perforator flaps is a safe and reliable method for repairing complex joint tissue defects in children. It provides accurate perforator localization, offering significant clinical value for the design and harvesting of LFCA chimeric perforator flaps in pediatric patients.

Objective:To explore the research hotspots and emerging trends in the field of breast cancer-associated lymphedema, as reflected in the domestic and international literatures.Methods:The bibliometric method was used to retrieve literatures related to breast cancer-associated lymphedema from the Wanfang Database, China National Knowledge Infrastructure, China Science and Technology Journal Database, and the core collection of Web of Science, covering the time range from January 1, 2014, to December 31, 2023. CiteSpace 6.3.R3 software was employed for analysis, which involved statistical assessment of the publication volume, authors, countries, and institutions, as well as the identification of highly cited papers. A co-occurrence analysis of keywords was performed, followed by burst analysis and cluster analysis based on the results.Results:A total of 4 419 Chinese-language articles were retrieved from the three Chinese databases, of which 2 888 were included after duplicate removal. The Web of Science Core Collection yielded 2 142 English-language articles. Among the domestic authors, the top three with the highest publication counts were Zhang Lijuan (25 papers), Jia Jie (22 papers), and Zhong Qiaoling (21 papers). In the English-language literatures, the top three authors with the highest number of publications were Singhal D (32 papers), Devoogdt N (27 papers), and Boyages J (27 papers). A total of 76 countries worldwide had conducted research on breast cancer-associated lymphedema, with the United States contributing the most publications (748 papers), followed by China (227 papers). In total, 642 institutions worldwide had publications on this topic, with 385 domestic institutions. The leading domestic institution was Jiangxi Provincial Cancer Hospital (31 papers), while the top foreign institution was Harvard University (118 papers). The Top 10 most cited papers focused on key research areas in breast cancer-associated lymphedema. A total of 359 Chinese keywords and 513 English keywords were included for co-occurrence analysis. The five most frequent Chinese keywords were quality of life, nursing, complications, upper limb function, and risk factors. In the English literatures, the top five most frequent keywords were quality of life, women, survivors, risk factors, and surgery. Cluster analysis of the keywords revealed 16 clusters in the Chinese literatures, with the largest cluster "functional exercise", while 17 clusters were identified in the English literatures, with the largest cluster "lymph node transfer". The five most consistent clusters in Chinese literatures were lymphatic drainage, rehabilitation, functional impairment, evidence-based nursing, and circumferential lymphatics. In recent years, emerging topics in Chinese literatures included lymphatic drainage, breast reconstruction, and pathophysiology. In English literatures, the consistent top clusters were transplantation, node biopsy, morbidity, identification, and randomized trials, with recent emerging topics including obesity, adipose tissue, healing approaches, lymphatic microsurgical preventive healing approach, and anastomosis.Conclusion:The research on breast cancer-related lymphedema both domestically and internationally shows similarities and differences in direction and focus. Common research hotspots across both domestic and international studies include lymphatic drainage, functional exercise, health behaviors, and lymph node transfer. Recent emerging topics in Chinese literatures include lymphatic drainage, breast reconstruction, and pathophysiology. In contrast, English literatures focus more on the areas such as obesity, adipose tissue, healing methods, and lymphatic anastomosis.

Objective:To analyze serum inflammatory factors associated with antihistamine resistance in patients with chronic spontaneous urticaria (CSU) .Methods:A total of 88 CSU patients were enrolled from Guangzhou Dermatology Hospital from January 2022 to December 2024. All patients received antihistamine treatment according to the "Guideline for diagnosis and treatment of urticaria in China (2022) " . Based on the 7-day urticaria activity score (UAS7) after 4-week treatment, these patients were divided into an antihistamine-sensitive group and an antihistamine-resistant group. Serum levels of inflammatory factors at the initial visit were analyzed using the Olink-targeted proteomics technology. Specific biomarkers associated with antihistamine resistance were identified, and Spearman correlation analysis was carried out to analyze correlations among differentially expressed proteins. A logistic regression model was constructed based on the Olink proteomics data, and the predictive performance of the model was evaluated using receiver operating characteristic (ROC) curve analysis. Measurement data were expressed as mean ± standard deviation or median (lower quartile, upper quartile) .Results:The 88 CSU patients aged 12 to 81 (38.78 ± 13.89) years, with the disease duration being 18 (7.00, 60.00) months. There were 32 patients in the antihistamine-sensitive group and 56 in the antihistamine-resistant group. No significant differences were found between the two groups in terms of age, disease duration, gender, or history of allergic diseases (all P > 0.05) . After 4 weeks of antihistamine treatment, the UAS7 score was significantly higher in the antihistamine-resistant group (25.00 [15.25, 31.00] points) than in the antihistamine-sensitive group (0.50 [0.00, 4.00] points; Z = -7.08, P < 0.001) . The Olink-targeted proteomics identified 5 differentially expressed proteins between the two groups: compared with the antihistamine-sensitive group, the antihistamine-resistant group showed > 2-fold higher expression of fibroblast growth factor 19 (FGF19) , interleukin-15 receptor subunit alpha (IL-15RA) , eotaxin (CCL11) , and monocyte chemoattractant protein-1 (MCP-1) ; in contrast, the expression of sulfotransferase 1A1 (ST1A1) in the antihistamine-sensitive group was 2.54 times that in the antihistamine-resistant group. Among the differentially expressed proteins, MCP-1 showed the highest specificity (1.00) for predicting antihistamine resistance, followed by CCL11 (0.97) . Correlation analysis revealed a significant positive correlation between MCP-1 and CCL11, and a significant negative correlation between IL-15RA and ST1A1. ROC curve analysis showed that MCP-1 and CCL11 had area under the curve values of 0.603 and 0.630, respectively, in predicting antihistamine resistance. Conclusion:MCP-1 and CCL11 may be potential biomarkers for predicting antihistamine resistance in CSU patients.

BACKGROUND: Severe stroke has high rates of mortality and morbidity. This study aimed to investigate the clinical course, causes of worsening, and outcomes of severe ischemic stroke. METHODS: This prospective, multicenter cohort study enrolled adult patients admitted ≤30 days after ischemic stroke from nine hospitals in China between September 2017 and December 2019. Severe stroke was defined as a score of ≥15 on the National Institutes of Health Stroke Scale (NIHSS). Clinical worsening was defined as an increase of 4 in the NIHSS score from baseline. Unfavorable functional outcome was defined as a modified Rankin scale score ≥3 at 3 months and 1 year after stroke onset, respectively. We performed Logistic regression to explore baseline features and reperfusion therapies associated with clinical worsening and functional outcomes. RESULTS: Among 4201 patients enrolled, 854 patients (20.33%) had severe stroke on admission. Of 3347 patients without severe stroke on admission, 142 (4.24%) patients developed severe stroke in hospital. Of 854 patients with severe stroke on admission, 33.95% (290/854) experienced clinical worsening (median time from stroke onset: 43 h, Q1-Q3: 20-88 h), with brain edema (54.83% [159/290]) as the leading cause; 24.59% (210/854) of these patients died by 30 days, and 81.47% (677/831) and 78.44% (633/807) had unfavorable functional outcomes at 3 months and 1 year respectively. Reperfusion reduced the risk of worsening (adjusted odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.12-0.49, P  <0.01), 30-day death (adjusted OR: 0.22, 95% CI: 0.11-0.41, P  <0.01), and unfavorable functional outcomes at 3 months (adjusted OR: 0.24, 95% CI: 0.08-0.68, P <0.01) and 1 year (adjusted OR: 0.17, 95% CI: 0.06-0.50, P  <0.01). CONCLUSIONS: Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes. REGISTRATION ClinicalTrials.gov , NCT03222024.
