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.

Objective: To investigate the incidence and influencing factors of new onset suicidal behaviors among junior and senior high school students, so as to provide evidence for early warning and intervention. Methods: Using a cluster sampling method, baseline data were collected from September to November 2023 among 2 379 adolescents selected from 2 junior high schools, 2 general senior high schools and 2 vocational senior high schools in Wuhan, Hubei Province, with follow up carried out from September to November 2024. Data were collected using the School Adaptation Scale, the Essential Resilience Scale, the Personal Social Support Scale, the Adverse Childhood Experiences Questionnaire, the Adolescent Life Events Scale, the Pittsburgh Sleep Quality Index, the Center for Epidemiologic Studies Depression Scale, and the Columbia-Suicide Severity Rating Scale. Multivariate Logistic regression analysis was used to identify factors influencing new onset suicidal behavior among junior and senior high school students. Results: Among junior and senior high school students without suicide risk at baseline, 53.55% remained stable risk free during follow up, while 13.28% developed new suicidal behavior during follow up, of which suicidal ideation, suicide plan and suicide attempts accounted for 11.69%, 8.83% and 6.52%, respectively. Multivariate Logistic regression revealed that increased depressive symptoms at follow up elevated the risk of overall new onset suicidal behaviors ( OR =4.14), ideation ( OR = 4.59), plans ( OR =4.24), and attempts ( OR =4.09); poor sleep quality also increased the risk of overall new onset suicidal behaviors ( OR =2.23), plans ( OR =2.03), and attempts ( OR =2.65) (all P <0.05). Non boarding junior and senior high school students had lower risks of overall new onset suicidal behaviors and ideation ( OR=0.70 and 0.49, respectively); secondary school students with academic performance ranking in the top 20%-30% of their class had a lower risk of new onset ideation ( OR =0.27); and those whose place of origin was outside the city had a lower risk of new onset plans ( OR =0.49) (all P <0.05). Conclusions New onset suicidal behaviors among junior and senior high school students exhibit dynamic and stage specific differences. Depressive symptoms serve as a common core risk factor across all stages, whereas sleep quality, academic performance, boarding status, and place of origin exert differential influences at distinct stages.

ObjectiveTo investigate the mechanism by which Sini San （SNS） treats liver fibrosis through regulating the polarization of intrahepatic Kupffer cells. MethodsSixty SPF-grade male Balb/c mice were randomized into blank control， model， silymarin （0.2 g·kg^-1）， and low-， medium-， and high-dose （2.93， 5.85， 11.70 g·kg^-1， respectively） SNS groups. A mouse model of liver fibrosis was induced by intraperitoneal injection of CCl₄. After 5 weeks of administration， the body mass， liver pathological changes ［Hematoxylin and Eosin （HE）， Masson， and Sirius red staining］， serum biochemical indicators ［alkaline phosphatase （ALP）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT）］， liver fibrosis markers ［procollagen type Ⅲ （PCⅢ）， laminin （LN）， and hyaluronic acid （HA）］， inflammatory cytokines ［interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10）］， and fibrosis-related proteins ［α-smooth muscle actin （α-SMA）， collagen type Ⅰ （Col Ⅰ）， and collagen type Ⅲ （Col Ⅲ）］ were assessed. A co-culture system of THP-1 cells （M1 macrophages） and human hepatic stellate cells （LX-2） was established. The cell experiment was designed with blank control （LX-2 alone）， model （LX-2 + M1 macrophages）， and low-， medium-， and high-dose SNS （co-culture with 5%， 10%， or 20% SNS-containing serum， respectively） groups. Cell viability， inflammatory cytokines， and macrophage phenotype were examined. Human primary hepatic Kupffer cells were allocated into blank control， M1 （LPS 100 μg·L^-1+IFN-γ 20 μg·L^-1）， M2 （IL-4 20 μg·L^-1+IL-13 20 μg·L^-1）， M1+M2， M1+SNS （supplemented with 10% SNS-containing serum for 2 h after culture under M1 conditions for 24 h）， M2+SNS （supplemented with 10% SNS-containing serum for 2 h after culture under M2 conditions for 24 h）， and M1+M2+SNS groups （supplemented with 10% SNS-containing serum for 2 h after culture under M1+M2 conditions for 24 h）， and the expression of nuclear factor-κB （NF-κB） p65 and signal transducer and activator of transcription 3 （STAT3） at protein and mRNA levels was determined. ResultsCompared with the blank group， the model group exhibited increased serum levels of ALT， AST， ALP， PCⅢ， LN， HA， IL-6， and TNF-α， upregulated protein and mRNA levels of α-SMA， Col Ⅰ， and Col Ⅲ in the liver tissue （P<0.05， P<0.01）， and decreased IL-10 level and STAT3 mRNA level （P<0.05， P<0.01）， accompanied by marked collagen deposition and inflammatory infiltration in the liver. Compared with the model group， all doses of Sini San reversed these alterations （P<0.05， P<0.01）， with the high-dose group showing the most pronounced effects. Cell experiments demonstrated that， compared with the blank control group， the model group had elevated levels of pro-inflammatory cytokines （IL-1β， IL-6， and TNF-α） and upregulated protein and mRNA levels of M1 markers ［cluster of differentiation 86 （CD86， inducible nitric oxide synthase （iNOS）， and monocyte chemoattractant protein-1 （MCP-1）］ （P<0.01）， along with declined level of IL-10 and downregulated expression of M2 markers ［（CD163， CD206， and arginase-1 （Arg-1）］ （P<0.05，P<0.01）. Compared with the model group， treatment with Sini San-containing serum at various concentrations lowered the levels of pro-inflammatory cytokines and expression of M1 markers （P<0.05， P<0.01）， while increasing the IL-10 level and M2 marker expression （P<0.05， P<0.01）. Additionally， Sini San downregulated the mRNA level of NF-κB and upregulated the mRNA level of STAT （P<0.05， P<0.01）. In the experiment with human primary Kupffer cells， compared with the blank group， the M1 group showed increased NF-κB p65 expression （P<0.01） and decreased STAT3 expression （P<0.05）， whereas the M2 group exhibited increased STAT3 expression （P<0.01）. Compared with the respective model groups， Sini San-containing serum reversed the M1-induced overexpression of NF-κB p65 （P<0.05， P<0.01） and further enhanced the M2-induced STAT3 expression （P<0.05， P<0.01）. ConclusionSini San can inhibit the NF-κB p65/STAT3 signaling pathway and repolarize intrahepatic Kupffer cells from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype to attenuate inflammation and suppress hepatic stellate cell activation and collagen deposition， thereby exerting anti-fibrotic effect.

AIM To observe the protective effects and mechanism of Shuli Jiangzhuo Formula on cardiac function in a rat model of uremic cardiomyopathy(UCM).METHODS The successful UCM models established by 5/6 nephrectomy were randomly allocated into the model group,the valsartan group(8.33 mg/kg),and the low-dose,medium-dose and high-dose Shuli Jiangzhuo Formula groups(7.19,14.38,28.76 g/kg),in contrast to those of the sham operation group,followed by 8 weeks respective drug administration.Upon the completion of the pharmacological intervention,the rats had the left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),ejection fraction(EF)and fractional shortening(FS)measured by echocardiography;the whole heart mass index(HMI)and left ventricular mass index(LVMI)detected;the renal function(serum creatinine,blood urea nitrogen)and the hemoglobin concentration detected;the mitochondrial morphology analyzed by observation of cardiomyocyte ultrastructure using transmission electron microscopy;the DNA damage in cardiomyocytes detected by TUNEL staining;the serum levels of IL-1β,IL-18 and BNP detected by ELISA;and the myocardial mRNA and protein expressions of NLRP3,Caspase-1 and IL-1β detected by RT-qPCR and Western blot.RESULTS Compared with the sham operated controls,the model group demonstrated significant elevation of serum creatinine and urea nitrogen(P＜0.01);decreased hemoglobin concentration(P＜0.01);disorganized myocardial collagen fiber architecture,and pronounced mitochondrial swelling with ultrastructural damage;decreased EF and FS(P＜0.05);increased LVEDD and LVESD(P＜0.01);increased HMI and LVMI(P＜0.01);increased levels of serum IL-1β,IL-18 and BNP(P＜0.01);increased cardiomyocyte pyroptosis(P＜0.01);and enhanced mRNA and protein expressions of NLRP3,Caspase-1 and IL-1 β(P＜0.01).Compared to model group controls,the high-dose Shuli Jiantuo Formula intervention exhibited decreased levels of serum creatinine and urea nitrogen(P＜0.01);increased hemoglobin concentration(P＜0.01);reduced DNA fragmentation,alleviated mitochondrial swelling and mitigated ultrastructural damage;reduced LVEDD and LVESD(P＜0.05,P＜0.01);decreased HMI and LVMI(P＜0.01);downregulated levels of serum IL-1β,IL-18 and BNP(P＜0.01);decreased cardiomyocyte pyroptosis(P＜0.01);and inhibited mRNA and protein expressions of NLRP3,Caspase-1 and IL-1β(P＜0.05,P＜0.01).CONCLUSION Shuli Jiangzhuo Formula demonstrates dual cardiorenal protective effects in UCM rats through suppression of the left ventricular hypertrophy progression and inhibition of the adverse ventricular remodeling processess.The therapeutic efficacy primarily stems from targeted suppression of NLRP3/Caspase-1 signaling pathway activation and substantial attenuation of cardiomyocyte pyroptosis cascade.

OBJECTIVE Aimed to comprehensively evaluate various immunological changes in a mouse model of eosinophilic chronic rhinosinusitis with nasal polyps(ECRSwNP)induced by ovalbumin(OVA)combined with Aspergillus protease(AP),including nasal polyps-like lesions,subepithelial collagen deposition,inflammatory cell infiltration,epithelial barrier function,and olfactory neuron damage.METHODS C57BL/6 mice were challenged with OVA and AP for 12 weeks.Hematoxylin-eosin(HE),periodic acid-Schiff(PAS),and Masson staining were used to observe the changes of nasal polyps-like lesions,goblet cell hyperplasia,and subepithelial collagen deposition.Immunohistochemistry staining(IHC)was employed to detect the changes of various inflammatory cells,olfactory neurons,and the expression of epithelial tight junction proteins in the nasal and sinus mucosa.RESULTS Compared to the control group,the OVA and AP group showed significantly increased epithelial thickness,noticeable nasal polyps-like lesions,marked subepithelial collagen deposition,and goblet cell hyperplasia in the nasal and sinus mucosa.IHC results revealed a significant increase in eosinophils,along with higher numbers of neutrophils,mast cells,and CD4+T cells in the OVA and AP group.Additionally,the expression of tight junction proteins ZO-1 and E-cadherin in the nasal and sinus mucosa and the area of OMP+olfactory neurons in the olfactory epithelium were significantly lower in the OVA and AP group compared to the control.CONCLUSION Continuous exposure to OVA combined with AP successfully induces ECRSwNP.The establishment of this model provides a foundation for further research into the pathogenesis and the evaluation of new therapeutic strategies for ECRSwNP.

Chronic sinusitis with nasal polyps(CRSwNP)is a highly heterogeneous chronic inflammatory disease,that persistently impacts patients'quality of life.To date,its etiology and pathogenesis remain incompletely unclear.Animal models serve as crucial tools for exploration of CRSwNP pathogenesis However,there is still a lack of a recognized mature and stable mouse model of CRSwNP in basic research.The stable mouse model of CRSwNP has become a key bottleneck in the analysis of the pathogenesis.This paper systematically reviews existing construction methodologies,inflammatory phenotypes,and applicability of murine CRSwNP models.By comparing their advantages and limitations,we will explore future optimization directions.This review will provide a theoretical basis and foundation for the basic research and clinical precision treatment of CRSwNP.

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: Emerging evidence suggests that exposure to ultrafine particulate matter (UPM, aerodynamic diameter < 0.1 µm) is associated with adverse cardiovascular events. Previous studies have found that Shenlian (SL) extract possesses anti-inflammatory and antiapoptotic properties and has a promising protective effect at all stages of the atherosclerotic disease process. In this study, we aimed to investigated whether SL improves UPM-aggravated myocardial ischemic injury by inhibiting inflammation and cell apoptosis. METHODS: We established a mouse model of MI+UPM. Echocardiographic measurement, measurement of myocardialinfarct size, biochemical analysis, enzyme-linked immunosorbent assay (ELISA), histopathological analysis, Transferase dUTP Nick End Labeling (TUNEL), Western blotting (WB), Polymerase Chain Reaction (PCR) and so on were used to explore the anti-inflammatory and anti-apoptotic effects of SL in vivo and in vitro. RESULTS: SL treatment can attenuate UPM-induced cardiac dysfunction by improving left ventricular ejection fraction, fractional shortening, and decreasing cardiac infarction area. SL significantly reduced the levels of myocardial enzymes and attenuated UPM-induced morphological alterations. Moreover, SL significantly reduced expression levels of the inflammatory cytokines IL-6, TNF-α, and MCP-1. UPM further increased the infiltration of macrophages in myocardial tissue, whereas SL intervention reversed this phenomenon. UPM also triggered myocardial apoptosis, which was markedly attenuated by SL treatment. The results of in vitro experiments revealed that SL prevented cell damage caused by exposure to UPM combined with hypoxia by reducing the expression of the inflammatory factor NF-κB and inhibiting apoptosis in H9c2 cells. CONCLUSION Overall, both in vivo and in vitro experiments demonstrated that SL attenuated UPM-aggravated myocardial ischemic injury by inhibiting inflammation and cell apoptosis. The mechanisms were related to the downregulation of macrophages infiltrating heart tissues.
