Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

ObjectiveTo investigate the independent risk factors for decompensation in patients with liver cirrhosis， to construct a nomogram-based risk assessment model， and to assess its risk assessment performance and clinical value by comparing it with Model for End-Stage Liver Disease （MELD）， MELD combined with serum sodium concentration （MELD-Na）， and MELD 3.0 scoring system. MethodsA retrospective analysis was performed for 514 patients with liver cirrhosis who attended The First Hospital of Shanxi Medical University from January 2020 to May 2025， and related data were collected， including demographic data and laboratory markers. According to the presence or absence of decompensation， the patients were divided into compensation group with 275 patients and decompensation group with 239 patients. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The least absolute shrinkage and selection operator regression analysis was used for screening of variables， and the multivariate logistic regression analysis was used to identify independent risk factors for decompensated liver cirrhosis and construct a nomogram model. The receiver operating characteristic （ROC） curve， calibration curve， and decision curve analysis were used to assess the discriminatory ability， calibration， and net clinical benefit of the model. ResultsThe multivariate logistic regression analysis showed that low hemoglobin （odds ratio ［OR］=0.984， 95% confidence interval ［CI］： 0.969　—　0.999， P<0.05）， low lymphocytes （OR=0.564， 95%CI： 0.383　—　0.830， P<0.05）， high international normalized ratio （OR=3.131， 95%CI： 1.242　—　7.891， P<0.05）， and low serum sodium （OR=0.922， 95%CI： 0.872　—　0.975， P<0.05） were independent risk factors for decompensation events in patients with liver cirrhosis. Construct the prediction model equation： Logit（P）=intercept value－0.016×hemoglobin－0.573×lymphocytes+1.141×INR－0.081×serum sodium. The nomogram constructed based on these factors had a good discriminatory ability， with an area under the ROC curve （AUC） of 0.787， a specificity of 77.8%， and a sensitivity of 67.4%， and it had significantly better predictive performance than MELD score （AUC=0.718）， MELD-Na score （AUC=0.719）， and MELD 3.0 score （AUC=0.725）. The calibration curve showed good consistency between the probability of risk assessed by the model and the observed probability. The decision curve analysis showed that compared with the MELD-based scores， this model provided higher net clinical benefit across a wide range of risk thresholds. ConclusionThis study successfully constructed and validated a nomogram risk assessment model incorporating hemoglobin， international normalized ratio， lymphocytes， and serum sodium. This model has good clinical practicability and can help to achieve early identification of high-risk patients with decompensated liver cirrhosis and optimize intervention strategies in clinical practice.

Objective: This study investigates the potential of radiomics to predict postoperative progression of ossification of the posterior longitudinal ligament (OPLL) after posterior cervical spine surgery. Methods: This retrospective study included 473 patients diagnosed with OPLL at Peking University Third Hospital between October 2006 and September 2022. Patients underwent posterior spinal surgery and had at least 2 computed tomography (CT) examinations spaced at least 1 year apart. OPLL progression was defined as an annual growth rate exceeding 7.5%. Radiomic features were extracted from preoperative CT images of the OPLL lesions, followed by feature selection using correlation coefficient analysis and least absolute shrinkage and selection operator, and dimensionality reduction using principal component analysis. Univariable analysis identified significant clinical variables for constructing the clinical model. Logistic regression models, including the Rad-score model, clinical model, and combined model, were developed to predict OPLL progression. Results: Of the 473 patients, 191 (40.4%) experienced OPLL progression. On the testing set, the combined model, which incorporated the Rad-score and clinical variables (area under the receiver operating characteristic curve [AUC] = 0.751), outperformed both the radiomics-only model (AUC = 0.693) and the clinical model (AUC = 0.620). Calibration curves demonstrated good agreement between predicted probabilities and observed outcomes, and decision curve analysis confirmed the clinical utility of the combined model. SHAP (SHapley Additive exPlanations) analysis indicated that the Rad-score and age were key contributors to the model’s predictions, enhancing clinical interpretability. Conclusion Radiomics, combined with clinical variables, provides a valuable predictive tool for assessing the risk of postoperative progression in cervical OPLL, supporting more personalized treatment strategies. Prospective, multicenter validation is needed to confirm the utility of the model in broader clinical settings.

AIM:To investigate the therapeutic effect of recombinant human interleukin-37(rhIL-37)inter-vention on extracellular matrix deposition in human bronchial epithelial cells exposed to fine particulate matter(PM2.5),and to explore the underlying mechanisms.METHODS:An airway injury cell model was established using normal human bronchial epithelial 16HBE cells treated with various concentrations(6.25,12.5,25 and 50 mg/L)of PM2.5.Western blot and immunofluorescence were employed to assess the expression level of Wnt family member 5a(Wnt5a).The con-centration of PM2.5 that maximized Wnt5a expression was identified as the optimal concentration for further analysis.The cells were divided into 3 groups,PM2.5+siRNA,PM2.5+Wnt5a siRNA and control+Wnt5a siRNA,to evaluate the expres-sion of fibronectin,the secretion of IL-6 and IL-1β,and the production of reactive oxygen species(ROS).A subsequent set of experiments was organized into PM2.5+rhIL-37,PM2.5 and control groups to determine whether rhIL-37 down-regu-lates the expression of Wnt5a and fibronectin,and reduces the secretion of IL-6 and IL-1β.RESULTS:(1)After 24 h of exposure to various concentrations of PM2.5,the expression of Wnt5a in 16HBE cells was significantly elevated,except at 50 mg/L,compared with control group(P＜0.05).The highest Wnt5a expression was observed at 12.5 mg/L PM2.5(P＜0.01).(2)Fibronectin expression peaked after 24 h of exposure to PM2.5 at 12.5 mg/L(P＜0.01).(3)Successful knock-down of Wnt5a resulted in decreased levels of fibronectin and nuclear factor E2-related factor(Nrf2).Additionally,the production of ROS and the secretion of IL-6 and IL-1β were significantly reduced compared with control group(P＜0.01).(4)The administration of rhIL-37 before PM2.5 exposure led to decreased levels of Wnt5a,fibronectin and Nrf2 compared with PM2.5 group(P＜0.05).Furthermore,rhIL-37 treatment reduced the ROS production and the secretion of IL-6 and IL-1β(P＜0.05).CONCLUSION:In vitro cell models demonstrate that PM2.5 can induce extracellular matrix deposition in bronchial epithelial cells,potentially through the modulation of inflammatory response and oxidative stress influenced by Wnt5a.Additionally,rhIL-37 appears to mitigate inflammatory response and oxidative stress by down-regulating Wnt5a.

Objective To evaluate the application value of aspiration catheter and debulking technology in the treatment of patients with intermediate-and high-risk pulmonary thromboembolism(PTE).Methods The clinical data of 28 patients with intermediate-and high-risk PTE were analyzed retrospectively.All subjects received thrombectomy using a 7F JR Guiding catheter.The success rate of surgery and the incidence of complications were counted,and the preoperative and postoperative values in heart rate(HR),systolic blood pressure(SBP),oxygen saturation(SO2),partial pressure of oxygen(PO2),Miller index,and mean pulmonary arterial pressure(MPAP)were compared.Results All patients were successfully treated,of which 26 cases obtained symptomatic relief after surgery.There were 2 cases of death in high-risk patients,of whom one died of myocardial infarction,and the other died of cerebral herniation after the procedure.One case reported the formation of pulmonary artery small dissection which disappeared within 2 months during conservative observation.The postoperative HR,Miller index,and MPAP decreased and SBP,SO2,and P()2 increased significantly than those of preoperative(P＜0.05).The follow-up period for this group ranged from 7 to 29 months,with a median follow-up of 14.6(7,19)months.During the follow-up period,no recurrences were observed.Conclusion The aspiration catheter and debulking technology demonstrate efficacy in treating intermediate-and high-risk PTE,and is associated with favourable success rates and low complication rates.The findings suggest its potential for wider clinical use.

Objective:To explore the characteristics of peripheral retinal defocus distribution in adult myopia and its relationship with refractive error.Methods:A cross-sectional study was conducted.A total of 270 myopic patients aged 18 to 46 years were enrolled at Tianjin Eye Hospital from January to March 2024.Data from the right eye were included in the analysis.Spherical power and cylindrical power were obtained using an autorefractor and the spherical equivalent (SE) was calculated.Corneal curvature parameters including flap keratometry (K1), steep keratometry (K2), and average keratometry (Km) were measured using the Pentacam anterior segment imaging analyzer.Central corneal thickness (CCT) and axial length (AL) were measured using the IOLMaster optical biometer.Peripheral defocus within a 53° area centered on the fovea was assessed using multispectral refractive topography.Based on the peripheral defocus data, the distribution patterns were classified into four types: hemilateral upturn type, saddle type, crater type, and relatively flat type.Characteristics of different tpes and their correlation with diopter were analyzed.This study followed the Declaration of Helsinki.The study protocol was reviewed and approved by the Medical Ethics Committee of Tianjin Eye Hospital (No.KY-2024020).All participants voluntarily participated and signed the informed consent form.Results:Of the different types of peripheral retinal defocus, 186 eyes (68.63%) were hemilateral upturn type, 45 eyes (16.61%) were crater type, 36 eyes (13.28%) were relatively flat type, and 3 eyes (1.11%) were saddle type.The crater type exhibited the lowest mean SE of (-6.18±1.50)D, while the relatively flat type showed the highest mean SE of (-3.88±0.87)D.There were significant differences in SE and AL among different peripheral defocus types ( F=15.469, 17.928, 3.431; all P<0.05).The hemilateral upturn type had significantly lower SE and spherical diopter than the relatively flat type, and crater type had significantly lower SE and spherical diopter compared to the hemilateral upturn type and relatively flat type significantly, and the hemilateral upturn type had longer AL than the relatively flat type (all P<0.05).There was no statistically significant difference in CCT, K1, K2, or Km among different peripheral defocus types ( F=0.861, 1.761, 2.603, 2.248; all P>0.05).Spherical power was weakly negatively correlated with superior, inferior, and temporal peripheral defocus ( r=-0.269, P<0.001; r=-0.176, P<0.01; r=-0.292, P<0.001).Age was positively correlated with superior and temporal peripheral defocus ( rs=0.213, P<0.001; rs=0.181, P=0.003), and negatively correlated with nasal peripheral defocus ( rs=-0.138, P=0.023). Conclusions:Among adult peripheral defocus patterns, the hemilateral upturn type is predominant.The crater type has the lowest mean spherical equivalent, while the relatively flat type has the highest.There are negative correlations between spherical power and the superior, inferior, and temporal peripheral defocus.

Objective:To explore the application effect of high-fidelity intelligent simulator combined with scenario simulation for emergency response training in the Department of Radiology, and to improve the emergency preparedness of medical, nursing, and technical staff in managing contrast agent adverse reactions.Methods:From January to July 2024, 132 medical, nursing, and technical staff from the Department of Radiology of a tertiary hospital in Chengdu City, China were selected as the training subjects. The high-fidelity intelligent simulator combined with scenario simulation teaching mode was used to conduct emergency response training for the participants. The differences in theoretical knowledge and post competence regarding contrast agent adverse reactions among the staff were compared before and after the training. A self-made questionnaire was used to investigate their needs and satisfaction of the emergency response training. SPSS 26.0 was used for data analysis. The differences in theoretical knowledge and post competence scores before and after training were compared using the paired samples t test. Results:After the training, the average score of theoretical knowledge examination increased from (84.32±10.19) points to (90.34±7.87) points, and the difference was statistically significant ( P<0.001). After the training, the scores of knowledge reserve, operational skills, situational decision-making ability, professional literacy, comprehensive literacy, and overall post competency were all significantly higher than those before the training ( P<0.05). The satisfaction score of emergency response training was (4.17±0.25) points. Conclusions:High-fidelity intelligent simulator combined with scenario simulation training improved the emergency preparedness and teamwork of radiology staff in clinical emergencies. The training received high recognition and satisfaction from the participants, which is of great significance for clinical emergency response and patient safety.

This study aims to investigate the biological function of the Clumping factor B(clfB)gene in Staphylococcus aureus.The recombinant plasmid pBT2-△clfB was constructed and elec-troporated into Staphylococcus aureus J57 to delete clfB by homologous recombination.The ex-pression plasmid pLI50-clfB was constructed,modified,and electroporated into clfB gene deletion strain △clfB and constructed a complementation strain(C△clfB).J57,△clfB,and C△clfB were cultured at 37℃ for 12 h,and the growth curves of each strain were plotted.The hemolytic properties of each strain were analyzed by contact method,the motility of each strain on TSA plates was determined,and the autolysis rate of each strain under the action of TritonX-100 was determined.Crystal violet staining was used to detect each strain's biofilm formation ability,and biofilm components formed by each strain were quantitatively analyzed.The K-B method was used to determine the sensitivity of each strain to commonly used antibiotics.ClfB gene deletion strain△clfB and the complemented strain C△clfB were successfully constructed.The growth curves of the deletion strain were almost consistent with those of the wild and complemented strains,and there was no significant difference.Compared with J57 and C△clfB,the hemoly ability and the athletic of △clfB decreased.In the condition of TritonX-100,the autolysis rate of △clfB was significantly lower than that of J57 and C△clfB(P＜0.01).Compared with J57 and C△clfB,the ability of △clfB to form biofilm was significantly lower than that of J57 and C△clfB(P＜0.05),and the content of extracellular DNA and protein in the biofilm was significantly decreased.In con-trast,the content of soluble polysaccharides was significantly increased(P＜0.05).Compared with J57 and C△clfB,△clfB was more sensitive to chloramphenicol,gentamicin,and kanamycin while more resistant to linezolid.ClfB gene is closely related to the autolysis,hemolytic activity,athlet-ic,and biofilm formation ability of Staphylococcus aureus,affecting the sensitivity of bacteria to certain antibiotics.
