Objective To evaluate the efficacy and safety of intraoperative pleural irrigation with Nocardia rubra cell-wall skeleton (N-CWS) for reducing pleural effusion drainage after radical surgery for lung cancer. Methods A retrospective analysis was conducted on the clinical data of lung cancer patients who underwent lobectomy and mediastinal lymph node dissection at the First Affiliated Hospital of Xiamen University between December 2024 and May 2025. Patients were divided into a control group and an irrigation group based on the intraoperative use of N-CWS. Patients in the irrigation group received pleural irrigation with 800 μg of N-CWS diluted in 10 mL of normal saline. The following outcomes were compared between the two groups: pleural effusion drainage volume at 0-24 h, 24-48 h, and 48-72 h postoperatively, degree of air leak, chest tube duration, postoperative length of stay, and the incidence of adverse events (fever, chest pain, and nausea and vomiting). Results A total of 245 patients were included (97 males, 148 females) with a mean age of (61.28±6.26) years, with 205 in the control group and 40 in the irrigation group. Compared to the control group, the irrigation group showed significantly lower pleural effusion drainage volumes at 0-24 h, 24-48 h, and 48-72 h, as well as shorter chest tube duration and postoperative length of stay (all P<0.05). There was no statistical difference in the degree of postoperative air leak (P=0.661). No significant differences were observed between the two groups regarding the highest body temperature within 72 h post-surgery (P=0.130), fever grade (P=0.196), severity of chest pain (P=0.105), or the incidence of nausea and vomiting (P=0.376). Conclusion Intraoperative pleural irrigation with N-CWS in patients undergoing lobectomy and mediastinal lymph node dissection for lung cancer can significantly reduce postoperative pleural effusion drainage volume, shorten chest tube duration and length of hospital stay. The procedure is safe and feasible.

Objective To explore the feasibility and reference value of allogeneic lung transplantation and postoperative monitoring in miniature pigs for lung transplantation research. Methods Two miniature pigs (R1 and R2) underwent left lung allogeneic transplantation. Complement-dependent cytotoxicity tests and blood cross-matching were performed before surgery. The main operative times and partial pressure of arterial oxygen (PaO2) after opening the pulmonary artery were recorded during surgery. Postoperatively, routine blood tests, biochemical blood indicators and inflammatory factors were detected, and pathological examinations of multiple organs were conducted. Results The complement-dependent cytotoxicity test showed that the survival rate of lymphocytes between donors and recipients was 42.5%-47.3%, and no agglutination reaction occurred in the cross-matching. The first warm ischemia times of D1 and D2 were 17 min and 10 min, respectively, and the cold ischemia times were 246 min and 216 min, respectively. Ultimately, R1 and R2 survived for 1.5 h and 104 h, respectively. Postoperatively, in R1, albumin (ALB) and globulin (GLB) decreased, and alanine aminotransferase increased; in R2, ALB, GLB and aspartate aminotransferase all increased. Urea nitrogen and serum creatinine increased in both recipients. Pathological results showed that in R1, the transplanted lung had partial consolidation with inflammatory cell infiltration, and multiple organs were congested and damaged. In R2, the transplanted lung had severe necrosis with fibrosis, and multiple organs had mild to moderate damage. The expression levels of interleukin-1β and interleukin-6 increased in the transplanted lungs. Conclusions The allogeneic lung transplantation model in miniature pigs may systematically evaluate immunological compatibility, intraoperative function and postoperative organ damage. The data obtained may provide technical references for subsequent lung transplantation research.

Objective:To investigate the anti-leukemic effects and resistance mechanisms of venetoclax in acute myeloid leukemia (AML). Genomic, transcriptomic, and clinical data from AML patients who underwent venetoclax drug sensitivity testing were downloaded from the Beat AML database. Correlation analysis was performed between these data and venetoclax sensitivity outcomes. Differentially expressed genes (DEGs) associated with venetoclax sensitivity were identified from transcriptomic data and subsequently validated using GEO database transcriptomic results and in vitro experiments (including Western blot). Functional enrichment analyses (KEGG and GSEA), transcription factor enrichment analysis (KnockTF), and data from public databases were employed to further investigate key genes and pathways influencing drug sensitivity.Results:After filtering the Beat AML cohort, data from 52 patient samples with available in vitro venetoclax sensitivity results were included for analysis. Patients with FLT3 mutations exhibited greater sensitivity to venetoclax compared to those with FLT3 wild-type. Correlation analysis between clinical information and drug sensitivity data indicated that higher peripheral blood tumor burden was associated with increased sensitivity to venetoclax. Transcriptomic analysis and in vitro experiments confirmed that venetoclax inhibits the FLT3-related signaling pathway, including downregulation of FLT3 expression and reduced phosphorylation of its downstream targets AKT and STAT5. KEGG pathway and KnockTF transcription factor enrichment analyses indicated that venetoclax resistance was associated with increased transcriptional activity of FOXM1 and STAT3. Moreover, high expression of FOXM1 and STAT3 correlated with shorter overall survival in patients.Conclusion:Venetoclax can inhibit the activation of FLT3-related signaling pathways. The activation of STAT3 and FOXM1 transcription factors is a potential key mechanism contributing to venetoclax resistance in AML.

In this paper, two cases of primary familial and congenital polycythemia (PFCP) were reported, and the literature was reviewed. PFCP is a rare autosomal dominant inherited disease caused by a gain-of-function mutation in the EPOR gene, resulting in a loss of negative regulation of erythrocyte proliferation. The two patients were young women with simple polycythemia and clear family history, and identified to carry the truncated mutation c.1316G>A (p.W439*) of EPOR gene. At present, there is no unified treatment plan for PFCP. Currently, there is no standardized treatment for PFCP; management primarily aligns with guidelines for polycythemia vera, focusing on preventing thrombotic complications. This article discusses the clinical features of PFCP, EPOR gene mutations, and their pathogenic mechanisms, while providing diagnostic and therapeutic recommendations based on existing literature.

Objective:To investigate the inhibitory effect of tripartite motif-containing 25 (TRIM25) on the replication of Japanese encephalitis virus (JEV) in cells and its molecular mechanism.Methods:Human glioma cells (U251 cells) and Kunming mice were infected with JEV, and then the cells and brain tissue samples were collected. The transcription levels of six TRIM genes were detected by real-time PCR, and the expression of TRIM25 in cells was detected by Western blot. U251 and A549 cells overexpressed with TRIM25 and U251 cells knocked out with TRIM25 gene were constructed. Cells were infected with JEV, and the replication of JEV was detected by viral plaque assay, real-time PCR and Western blot. The interaction of TRIM25 with viral proteins was investigated by co-immunoprecipitation (Co-IP) and indirect immunofluorescence assay. The expression of IFN-β in overexpressed TRIM25 cells was detected by real-time PCR and ELISA.Results:JEV infection promoted the expression of TRIM25 in cells and mouse brain tissues. TRIM25 overexpression restricted JEV replication in U251 and A549 cells, while TRIM25 knockout enhanced JEV replication. TRIM25 overexpression upregulated the level of IFN-β in cells. TRIM25 interacted with JEV capsid protein and promoted the degradation of capsid protein.Conclusion:TRIM25 can inhibit the replication of JEV in cells by upregulating IFN-β and promoting the degradation of JEV C protein.

Objective:To explore the impact of noise and dust exposure in the mechanical manufacturing industry on the risk of hypertension and abnormal electrocardiogram in workers, and their combined effects, in order to provide support for the prevention and treatment of occupational related diseases among workers.Methods:In January 2024, A convenience sampling method was used to study 2802 on-the-job workers who underwent occupational health check-ups from January 2023 to December 2023 at a machinery manufacturing enterprise in Baotou, Inner Mongolia. Blood pressure and electrocardiogram results were analyzed in the noise group, dust group, dust noise group and control group according to the exposure factors. For count data, the chi-square test was employed to analyze differences among groups. Additionally, a binary logistic regression model was utilized to assess the impact of dust and noise exposure on the prevalence of hypertension and electrocardiogram abnormalities.Results:The stratified analysis results showed that the differences in hypertension prevalence among the four groups were statistically significant ( P<0.001) in males, age groups >30-40 years, >40-50 years, >50 years, different exposure durations, and different enterprise sizes. For ECG abnormalities, significant differences were observed among the four groups ( P<0.001) in males, the age group >30-40 years, different enterprise sizes, and those with exposure durations ≤15 years. The trend test for hypertension prevalence across different age groups revealed that as age increased, the prevalence of hypertension showed an upward trend in the noise-exposed group, dust-exposed group, and combined dust-noise-exposed group ( χ2=10.76, 4.25, 6.60, P<0.001, 0.039, 0.010) . Binary regression model analyses revealed that the the risk of hypertension in the noise group, dust group and dust noise group was 2.63 times ( OR=2.63, 95% CI: 1.89~3.67, P<0.001) , 2.36 times ( OR=2.36, 95% CI: 1.76~3.16, P<0.001) and 2.69 times ( OR=2.69, 95% CI: 2.14~3.38, P<0.001) . Using ECG abnormalities as the dependent variable and incorporating the statistically significant variables from Table 1 as independent variables into the binary logistic regression model, the results showed no statistically significant differences in the risk of ECG abnormalities in the dust-exposed, noise-exposed, and combined dust-noise-exposed groups compared to the control group ( P> 0.05) . Conclusion:Combined exposure to dust and noise increases the risk of hypertension in workers and has a combined effect.

Objective:To construct a structural equation model for neck work-related musculoskeletal disorders (WMSDs) in the footwear industry and analyze the mediating effect of fatigue in the model.Methods:From November 2018 to December 2019, stratified cluster sampling was adopted to select all the workers (3565 people) from 7 footwear enterprises in Fujian Province as the research subjects. The incidence of WMSDs, fatigue and work-related condition were investigated by using the Chinese version of the Musculoskeletal Disorders Questionnaire. A structural equation model of individual factors, work type, work posture, work organization factors, and fatigue on neck WMSDs was constructed to analyze the mediating effect of fatigue among them.Results:The incidence rate of WMSDs in the neck of footwear workers was 39.6% (1413/3565) , and the incidence rate of neck fatigue was 46.6% (1662/3565) .The final structural equation model was constructed with a χ2/ df of 9.927, a goodness-of-fit index of 0.961, an adjusted goodness-of-fit index of 0.946, and a root mean square error of approximation of 0.050. Except for the χ2/ df, all other fit indicators met the standard. Individual factors and work posture factors had a direct effect on neck WMSDs, with standardized path coefficients of 0.101 and 0.077, respectively ( P<0.05) . Individual factors, work type, work posture, and work organization had indirect effects on neck WMSDs through fatigue, the standardized path coefficients of indirect effects were 0.163, 0.090, 0.206, 0.105, respectively, and the standardized path coefficients of the total effect were 0.264, 0.090, 0.282, and 0.105 respectively ( P<0.05) . The indirect effects of individual factors and work posture factors on neck WMSDs through fatigue accounted for 61.74% and 73.05% of the total effects, respectively. The standardized path coefficient of fatigue on WMSDs was 0.689 ( P<0.001) , with the highest coefficient among all paths. Conclusion:Individual factors, work type, work posture, and work organization factors are important influencing factors in the occurrence and development of neck WMSDs in the footwear industry, and fatigue plays an important mediating role in them.

Bone marrow edema (BME) of the temporomandibular joint is an abnormal change within the bone marrow that appears as low signal intensity on T1-weighted images and high signal intensity on T2-weighted images in MRI. It is commonly seen in patients with temporomandibular joint osteoarthritis. Studies have shown that BME is closely related to joint pain, disc displacement and bony degeneration, but its specific mechanism is not yet fully understood, potentially involving abnormal mechanical loading, inflammatory responses and imbalances in bone metabolism. Although BME is considered an early sign of osteoarthritis, BME persists in approximately 71.4% of patients after pain resolution , suggesting the complexity of its association with clinical symptoms. In recent years, advanced MRI techniques (such as T2 mapping and fat suppression sequences) have improved the detection rate of BME and facilitated the assessment of its dynamic changes. However, the exact role of BME in temporomandibular disorders remains controversial. This article reviews the etiology and mechanism, pathology, imaging characteristics, and correlation with clinical symptoms of BME in the temporomandibular joint, and proposing future research directions to to elucidate its significance in disease progression and to provide guidance for clinical diagnosis and treatment.

Objective:To investigate the causes and management strategies of anesthetic complications during percutaneous spinal endoscopic surgery under local anesthesia.Methods:A total of 16 800 patients (8 625 males and 8 175 females) who underwent percutaneous spinal endoscopic surgery under local anesthesia (including intravenous basic anesthesia) in Tianjin Hospital, Shandong Public Health Clinical Center and Hebei General Hospital from February 2012 to February 2023 were retrospectively analyzed. The average age was 45.3±21.6 years (range, 12-84 years). There were 220 cases of posterior cervical keyhole endoscopic surgery, 50 cases of thoracic transforaminal endoscopic surgery, 70 cases of thoracic posterior interlaminar endoscopic surgery, 11 670 cases of lumbar transforaminal endoscopic surgery, and 4 790 cases of lumbar posterior interlaminar endoscopic surgery. The occurrence time, clinical manifestations, management of intraoperative anesthesia complications were recorded, as well as surgical segments, puncture sites, complication symptoms, signs, outcome and prognosis.Results:All patients received percutaneous water-mediated uniaxial spinal endoscopic surgery under local anesthesia. There were 9 patients experienced anesthesia complications, including 6 cases of epidural diffusion of anesthetics and 3 cases of anesthetics mistakenly entering the subarachnoid space. There were 4 males and 5 females, aged 48.4±18.2 years (range, 28-84 years). There were 1 case of T 12L 1 disc herniation, 1 case of C 5-6 disc herniation, 3 cases of L 4-5 disc herniation and 4 cases of L 5S 1 disc herniation. Surgical segments and procedures: 1 case of C 5-6 posterior Keyhole endoscopic surgery, 1 case of T 12L 1 transforaminal endoscopic surgery, 2 cases of L 4-5 transforaminal endoscopic surgery, 1 case of L 4-5 interlaminar endoscopic surgery, and 4 cases of L 5S 1 interlaminar endoscopic surgery. Anesthesia complications all appeared 5-10 min after injection of local anesthetics, with symptoms of decreased oxygen saturation, decreased blood pressure, altered consciousness, and sensory and motor dysfunction of limbs. 6 patients with epidural diffusion of anesthetics recovered completely after symptomatic treatment in 5 cases, and 1 case was left with foot drop. Three patients with anesthetics mistakenly entering the subarachnoid space were immediately converted to the supine position, of which one recovered by mask oxygenation; 1 patient improved after emergency tracheal intubation, rehydration, and application of vasoconstrictive medications; and 1 patient developed multiple complications such as multiorgan failure, rhabdomyolysis, and sepsis after tracheal intubation, and recovered at 3 months after surgery with symptomatic treatment. Conclusions:Epidural diffusion and entering into subarachnoid space of anesthetics are serious complications of local anesthesia in percutaneous spinal endoscopic surgery. In addition to sensory and motor dysfunction of the limbs, the functions of the respiratory and circulatory systems can also be affected. It is necessary to be alert to the occurrence of anesthesia-related complications during operation and early identification and treatment.

Objective:To compare the clinical outcomes of APTT-HTO and Biplanar-high tibial osteotomy (Biplanar-HTO) in treating medial compartment knee osteoarthritis.Methods:A non-randomized controlled trial was conducted. Twenty-eight patients with medial compartment knee osteoarthritis who underwent HTO at the Affiliated Hospital of Guizhou Medical University from August 2021 to January 2022 were enrolled. Based on the patients' surgical preference, they were assigned to either the APTT-HTO group ( n=15) or the Biplanar-HTO group ( n=13), followed up for 12 months postoperatively. Postoperative pain Visual Analog Scale (VAS) scores, Knee Society Score (KSS), changes in patellar height (Caton-Deschamps Index, CDI), and posterior tibial slope (PTS) were compared between the two groups. Results:The APTT-HTO group demonstrated a significantly shorter operative time (64.13±4.85 min) compared to the Biplanar-HTO group (81.54±6.09 min) ( P<0.05). No significant differences were observed in intraoperative correction (APTT-HTO: 12.19°±4.85°; Biplanar-HTO: 11.23°±3.02°) or postoperative drainage volume (APTT-HTO: 47.00±13.79 ml; Biplanar-HTO: 47.00±11.17 ml) ( P>0.05). At 12-month follow-up (APTT-HTO: 13.93±2.05 months; Biplanar-HTO: 14.08±2.14 months; no dropouts), the APTT-HTO group showed no significant changes in PTS (9.32°±2.04° vs. preoperative 8.82°±1.89°) or CDI (0.95±0.11 vs. 0.98±0.11) ( P>0.05), while the Biplanar-HTO group exhibited increased PTS (13.27°±1.99° vs. 8.86°±1.99°) and decreased CDI (0.64±0.10 vs. 0.97±0.16) ( P<0.05). The differences in PTS and CDI between the APTT HTO group and the Biplanar HTO group at 12 months after surgery were statistically significant ( P<0.05). Both groups achieved significant clinical improvements: in APTT-HTO, VAS decreased (preopreation 4.80±1.01 to postopreation 1.06±0.88), KSS knee scores increased (47.67±12.03 to 87.93±4.38), and KSS function scores improved (48.00±4.93 to 67.00±5.91); in Biplanar-HTO, VAS reduced (5.08±1.12 to 1.85±1.14), KSS knee scores rose (46.85±11.48 to 85.85±5.11), and KSS function scores enhanced (46.92±5.60 to 66.92±5.22) ( P<0.05 for all). Complications included soft tissue irritation (2 cases per group), with Biplanar-HTO additionally reporting deep vein thrombosis (1 case), hinge fracture (1 case), and patella baja (3 cases). Conclusions:Both APTT-HTO and Biplanar-HTO effectively treat medial compartment knee osteoarthritis. However, APTT-HTO outperforms Biplanar-HTO in preventing postoperative patella infera and minimizing alterations in PTS.
