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 analyze the associations of physical activity with overweight/obesity, depressive symptoms, and their co-occurrence among junior and senior high school students, so as to provide reference for optimizing physical activity intervention strategies and promoting healthy lifestyles. Methods: From March to November 2023, a cross sectional survey was conducted among 90 457 junior and senior high school students aged 11-18 years in Zhejiang Province using a stratified cluster random sampling method. Data on physical activity and dietary behavior were collected through questionnaires, height and weight were measured. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). The Chi-square test was used to examine differences, and Logistic regression was applied to evaluate the associations of physical activity characteristics with overweight/obesity, depressive symptoms, and their co-occurrence. Additionally, the effectiveness of physical activity performed on rest days versus work days was examined. Results: The prevalence of overweight/obesity, depressive symptoms, and their co-occurrence among junior and senior high school students were 25.1%, 27.9%, and 6.7%, respectively, with significant sex differences ( χ 2=2 005.3, 587.7, 99.6, all P <0.01). Logistic regression analysis showed that students with insufficient physical activity had a higher risk of overweight/obesity compared with those with sufficient physical activity ( OR=1.12, 95%CI=1.06-1.17, P <0.01). Comparing to students who exercised 0-1 day per week, those who exercised 5-7 days per week were associated with a reduced risk of overweight/obesity and depressive symptoms ( OR=0.93, 95%CI =0.90-0.97; OR=0.95, 95%CI =0.91-0.99, both P <0.05). When total activity volume and frequency were held constant, students with sufficient rest day physical activity had lower risks of overweight/obesity, depressive symptoms, and their co-occurrence than those with insufficient rest day activity (all P < 0.01). Conclusions Sufficient amount of physical activity and higher frequency of rest day physical activity are significantly associated with lower risks of overweight/obesity, depressive symptoms, and their co-occurrence in adolescents. Physical activity performed on rest days may confer greater health benefits than activity performed on work days.

The surgical management of empyema (excluding those caused by mycobacterium tuberculosis and non-tuberculous mycobacteria) is rapidly evolving towards minimally invasive, precise, and stepwise approaches. The traditional three-stage classification (exudative, fibrinopurulent, and organizing) has limitations in guiding dynamic clinical decision-making. For the first time, this consensus explicitly identifies two critical junctures in the pathological progression of empyema: "early transformation" (stage Ⅰ to Ⅱ) and "late transformation" (stage Ⅱ to Ⅲ), and thereby constructs a corresponding "identification-early warning-intervention" stepwise therapeutic framework. The consensus emphasizes that proactive debridement via video-assisted thoracoscopic surgery should be performed during the early transformation phase to halt disease progression. Conversely, during the late transformation phase, therapeutic goals should be rationally adjusted to prioritize adequate drainage, avoiding futile pleural decortication. Moreover, the consensus underscores the pivotal role of precise perioperative etiological diagnosis (e.g. metagenomic nest-generation sequencing) and standardized anti-infective therapy. Integrating practical experiences from multiple thoracic surgery centers in China and relevant evidence-based literature, this consensus formulates recommendations on the precise definitions of staging, surgical indications for each phase, key technical points, perioperative management, and training systems. It aims to promote the standardized and individualized surgical management of empyema, ultimately optimizing patient prognosis.

Objective:To investigate the clinical features, diagnosis and treatment of eso-phageal fistula (EF) after radiofrequency catheter ablation (RFCA) for atrial fibrillation.Methods:The retrospective and descriptive study was conducted. The clinical data of 15 patients with EF after RFCA for atrial fibrillation who were admitted to Beijing Anzhen Hospital of Capital Medical University from January 2020 to December 2024 were collected. There were 11 males and 4 females, aged (64±7)years. All patients underwent surgical treatment. Observation indicators: (1) diagnosis and surgery; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean±SD, measurement data with skewed distribution were represented as M (range), and count data were represented as absolute numbers. Results:(1) Diagnodid and surgery. Of the 15 patients, radiofrequency catheter ablation included pulmonary vein isolation plus linear ablation in 13 cases and pulmonary vein isolation alone in 2 cases. The time to postoperative symptom onset of EF in 15 patients was (13±8)days. The main clinical manifestations included persistent chest pain in 14 cases, fever in 12 cases, dysphagia in 2 cases, and neurological symptoms in 2 cases (the same patient could have multiple symptoms). All patients presented with signs of infection of varying severity. Contrast-enhanced chest computed tomography (CT) or pulmonary vein CT angio-graphy revealed mediastinal emphysema, pneumopericardium with pericardial effusion, localized esophageal wall thickening with exudation, abnormalities in the posterior wall of the left atrium, or contrast extravasation in all patients. Cerebral imaging examination showed newly developed cerebral infarcts in 2 patients. The time from symptom onset to surgical intervention was 2(range, 1-10)days.All 15 patients underwent surgical treatment immediately after being diagnosed or highly suspected of EF via multidisciplinary collaboration. Among them, 11 patients with atrial-esophageal fistula (AEF) underwent left atrial defect repair plus left thoracic esophageal repair under cardio-pulmonary bypass through a median sternotomy, 3 patients with simple EF underwent left thoracic esophageal repair, 1 patient with AEF underwent atrial repair plus esophageal exclusion and drainage due to severe mediastinal infection. The diameter of the left atrial defect in the 15 patients was (12±5)mm, and the diameter of the esophageal defect was (11±4)mm. There was no patient cured with conservative treatment or converted to surgical treatment after failed conservative treatment.(2)Postoperative situations.Of the 15 patients, 3 cases developed pulmonary infection and were improved after anti-infective treatment. The duration of postoperative hospital stay was (21±5)days. (3) Follow-up. All 15 patients were followed up for 11(range, 3-18)months. Two of 15 patients died. One patient undergoing atrial repair plus esophageal diversion and drainage died postoperatively due to sepsis and multiple organ failure, and one patient undergoing left thoracic esophageal repair died of acute cardiac tamponade one week after surgery. The remaining 13 patients recovered well, without recurrence or new complications.Conclusions:The main clinical features of esophageal fistula after RFCA for atrial fibrillation include persistent chest pain, fever, accompanying signs of infection. Early contrast-enhanced chest CT or pulmonary vein CT angiography is helpful for diagnosis, and active surgical treatment after confirmation via multidisciplinary collaboration can improve patient prognosis.

AIM:To explore the role and mechanism of calcium-sensing receptor(CaSR)in regulating macro-phage polarization in hypertensive rats.METHODS:Male spontaneously hypertensive rats(SHR)and Wistar-Kyoto(WKY)rats were categorized into WKY group,SHR group,SHR+R568(CaSR agonist)group,and SHR+NPS2143(CaSR inhibitor)group.The thoracic aorta was isolated,and the expression of CaSR and macrophage polarization markers in the aorta was observed through immunofluorescence staining.The primary peritoneal macrophages of SHR and WKY rats were aseptically extracted following anesthesia.After intervention with R568 and NPS2143,the expression levels of M1 and M2 markers of peritoneal macrophages were observed by Western blot and immunofluorescence staining.The levels of interleukin(IL)-1β and IL-10 were measured by ELISA.The concentration of Ca2+in peritoneal macrophages was mea-sured by immunofluorescence.Western blot was employed to identify the expression of CaSR and nucleotide-binding oligo-merization domain-like receptor protein 3(NLRP3)inflammasome components.Following anesthesia,vascular smooth muscle cells(VSMCs)were isolated from SHR using an adherent method.Subsequently,a co-culture system was estab-lished with macrophage supernatant.The optimal action time for this co-culture system was determined through CCK-8 as-say.RESULTS:Compared with SHR group,activation of CaSR resulted in a significant decrease in the protein expres-sion of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers in the aorta(P<0.05).Compared with SHR group,administration of R568 led to a significant decrease in the protein ex-pression of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers(P<0.05)in peritoneal macrophages.Additionally,there was a notable reduction in the protein levels of NLRP3 inflammasome components(P<0.05).Furthermore,the fluorescence intensity of intracellular Ca2+was significantly en-hanced following R568 treatment(P<0.05).After administration of MCC950,an NLRP3 inflammasome inhibitor,the re-sults were consistent with those observed following R568 treatment,demonstrating statistical significance(P<0.05).This effect was reversed by the combined intervention of U73122,a phospholipase C(PLC)inhibitor(P<0.05).Compared with the control(0 h),the 24-h peritoneal macrophage supernatant exhibited the strongest capacity to enhance the viabili-ty of VSMCs after 24 h of culture(P<0.05).CONCLUSION:In hypertensive rats,the CaSR inhibits NLRP3 inflamma-some activation via the PLC-Ca2+signaling pathway,thereby mediating an increase in macrophage polarization towards the M2 phenotype and a decrease towards the M1 phenotype.

This research investigated the contamination level,distribution of drug-resistant strains,and molecular epidemiologi-cal characteristics of Campylobacter,and further explored transmission pathways and prevention strategies.Cecum,chicken carcass,chicken product,and environmental samples,as well as swabs from workers'hands,were collected from a slaughterhouse in a large broiler group in the Jiaodong area between August 2023 and July 2024.Quantitative contamination assessment of Campylobacter in chicken carcasses and chicken products was performed.After microbial mass spectrometry identification,the representative strains of different links were selected for drug resistance testing and whole genome sequencing(WGS).On the basis of the sequencing results,the resistance genes,virulence genes,multilocus sequence typing(MLST),and phylogenetic characteristics of representative strains were analyzed.Homology comparisons were performed between isolates and strains from patients with diarrhea in the NCBI database.A total of 297 Campylobacter strains were isolated from 806 samples,and the overall detection rate was 36.85%.The detection rate of Campylobacter was highest in the evisceration process(47.33%),followed by the cutting process(35.64%).Overall,the Campylo-bacter detection rate first increased,then decreased,and subsequently increased.Drug sensitivity testing revealed that 90 isolates were resistant to nalidixic acid and ciprofloxacin,and 94.97%of isolates were resistant to tetracycline.WGS showed that both Campylo-bacter jejuni(C.jejuni)and Campylobacter coli(C.coli)carried many drug resistance and virulence genes.ST-14176 of C.jejuni was isolated for the first time herein.The predominant ST-8261 strain of C.jejuni and ST-860,ST-829,and ST-1586 strains of C.coli are known to cause human diarrhea.LOS expression genes associated with Guillain-Barré syndrome(GBS)were detected in both C.jejuni isolates from the slaughter chain and patients with GBS.Some strains exhibited close genetic relatedness to human-derived Campylo-bacter strains from the NCBI database.The detection rate of Campylobacter in the slaughterhouse first increased,then decreased,and subsequently increased,and the quantitative contamination level of each link was similar to the detection rate.Quantitative analysis of chicken carcasses/products revealed that the average bacterial load was highest in eviscerated carcasses(102.80 cfu/g),and the high-est amount of Campylobacter in chicken products reached 451.80 cfu/g.Abundant drug resistance genes and virulence genes were iden-tified,and the drug resistance genes were highly correlated with the drug resistance rate.Therefore,surveillance intensity and control measures for Campylobacter in slaughter processes should be strengthened.

Objective:To introduce the research and innovations around the application of aquatic rehabilitation techniques in the treatment of lumbago, and to summarize specific methods and applications in aeromedicine. Literature resource and selection Literature on the prevention and treatment of lumbago using aquatic rehabilitation techniques as well as on the rehabilitation of lumbago in pilots was retrieved and selected. Literature quotation Sixty-one references were cited. Literature synthesis Aquatic rehabilitation techniques can be classified into shower therapy, immersion therapy, and aquatic exercise therapy according to treatment regimens. Among them, immersion therapy and aquatic exercise therapy are commonly used in the treatment of lumbago. Aquatic rehabilitation techniques can effectively alleviate patients′ lumbago, improve their functional disorders, and enhance their quality of life. Prior to aquatic therapy, patients with lumbago need to have their motor function assessed to tailor the treatment protocol based on diagnostic findings and specific therapeutic objectives. Aquatic rehabilitation techniques, when used to prevent and treat lumbago in pilots under convalescence, are not only more effective than land-based training, but also more accessible to pilots due to their comfort and compliance. Many of our military rehabilitation and convalescent centers in China have integrated modern aquatic rehabilitation techniques into rehabilitation treatment by drawing on their rich water resources so as to improve the physical and mental health, social adaptability and military adaptability of pilots. Conclusions:When used for the prevention and treatment of lumbago, aquatic rehabilitation techniques are highly effective, safe and enjoyable, so they should be made more accessible to pilots during convalescence.

Objective To investigate the serum levels of CC chemokine ligand(CCL)8 and CCL22 in chil-dren with severe Mycoplasma pneumoniae pneumonia(SMPP)and their clinical significance.Methods A to-tal of 103 children with SMPP admitted to the hospital from January 2021 to June 2023 were selected as the SMPP group.According to the simplified pediatric critical illness score,they were divided into non-critical group(37 cases),critical group(40 cases),and extremely critical group(26 cases).According to the prognosis of 28 d after admission,the patients were divided into poor prognosis group(22 cases)and good prognosis group(81 cases).At the same time,a total of 60 children with mild Mycoplasma pneumoniae pneumonia(MMPP)were enrolled as the MMPP group,and 60 healthy children who underwent physical were enrolled as the control group.Enzyme-linked immunosorbent assay was used to detect serum levels of CCL8,CCL22,C-reactive protein(CRP),procalcitonin(PCT),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6).Pearson or Spearman correlation analysis was used to analyze the relationship between CCL8,CCL22 levels and CRP,PCT,TNF-α,IL-6 and the disease severity.Multivariate Logistic regression was used to analyze the influencing factors for the poor prognosis of children with SMPP.The receiver operating characteristic(ROC)curve was used to evaluate the value of CCL8 and CCL22 in predicting the poor prognosis of children with SMPP.Re-sults Compared with the control group,the levels of CCL8,CCL22,CRP,PCT,TNF-α and IL-6 were signifi-cantly increased in the SMPP group and MMPP group(P<0.05),and the levels of the above indexes in the SMPP group were significantly higher than those in the MMPP group(P<0.05).Compared with the non-critical group,the levels of CCL8,CCL22,CRP,PCT,TNF-α and IL-6 in the extremely critical group and the critical group were increased(P<0.05),and the levels of the above indexes in the extremely critical group were increased more significantly than those in the critical group(P<0.05).The levels of CCL8 and CCL22 in SMPP group were positively correlated with disease severity,CRP,PCT,TNF-α and IL-6(P<0.05).Com-pared with the good prognosis group,the levels of CCL8,CCL22,CRP,PCT,TNF-α and IL-6 in the poor prog-nosis group were increased(P<0.05).Increased serum levels of CRP,PCT,TNF-α,IL-6,CCL8,and CCL22 were independent risk factors for poor prognosis in children with SMPP(P<0.05).The area under the curve of serum CCL8,CCL22 and their combination for predicting poor prognosis was 0.807,0.801 and 0.907,re-spectively.The predictive value of combined detection of CCL8 and CCL22 was greater than that of each index alone(Z=1.811,1.864,P=0.029,0.025).Conclusion The serum levels of CCL8 and CCL22 are increased in children with SMPP,and are closely related to the severity and prognosis of the disease.Early combined de-tection of CCL8 and CCL22 can be used as a marker to predict the poor prognosis of children with SMPP.
