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.

Liver injury due to acetaminophen overdose is one of the main causes of acute liver failure， with a complex pathogenesis. In this process， liver sinusoidal endothelial cell （LSEC） injury is a key early event jointly mediated by factors such as oxidative stress， cell apoptosis， and imbalance between fibrinolysis and coagulation. Subsequent LSEC dysfunction further induces sinusoidal microcirculatory disturbances， amplifies the inflammatory response， impairs the regeneration and repair abilities of the liver， and finally causes hepatocyte necrosis. This article systematically elaborates on the critical role and molecular mechanism of LSEC in acetaminophen-induced liver injury， in order to provide a theoretical basis for novel therapeutic strategies and research directions.

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.

AIM To establish an HPLC-MS/MS method for the simultaneous residue determination of 11 plant growth regulators(PGRs)in Renshen Guben preparations,and to conduct a risk assessment.METHODS The analysis was performed on a 40 ℃ thermostatic ACQUITY UPLC ? Waters HSS T3 column(2.1 mm×100 mm,1.8 μm),with the mobile phase of acetonitrile-0.1％formic acid(containing 5 mmol/L ammonium formate)flowing at 0.30 mL/min in a gradient elution manner,and electro spray ionization was employed in both positive and negative ion scanning,with multiple reaction monitoring mode.The chronic and acute exposure risk values of the detected PGRs were calculated and assessed based on residue levels,health guidance values,and exposure estimates.RESULTS Eleven PGRs exhibited good linear relationships within their own ranges(R2 ≥ 0.990),whose average recoveries were 70.0％-120.0％,with RSDs all below 12.0％.In both oral liquid and pill forms,mepiquat chloride showed the highest average residue levels,while sodium 5-nitroguaiacolate exhibited the highest acute risk value(0.765 7,0.908 1)and chronic risk value(0.023 1,0.027 0).CONCLUSION Although PGRs residues are detected in Renshen Guben preparations,all levels remained within safe limits.

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 To provide scientific and reasonable recommendations for the identification of Anaerobio-spirillum succiniciproducens in clinical microbiology laboratories by comparing the effectiveness of biochemical methods,matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS),and 16S rRNA gene sequencing.METHODS Methodological evaluation was conducted.A strain of A.succiniciprodu-cens was isolated on Mar.27,2023 from a patient with sepsis caused by a dog bite,who was admitted to Guang-dong Nongken Central Hospital,and analyzed for the morphological characteristics,culture methods,and colony features.The identification of the isolated strain was conducted by the automated microbial identification and anal-ysis system(VITEK 2 Compact 2,bioMerieux),MALDI-TOF MS including VITEK MS,MALDI Biotyper,Au-tof ms 1000,and EX-Accuspec,as well as 16S ribosomal RNA(rRNA)gene sequencing.The performance of each method was evaluated.RESULTSA.succiniciproducens was a strictly anaerobic gram-negative spiral bacteri-um,characterized by slow growth,flat and colorless transparent colonies,and negative oxidase and catalase activ-ity.When using VITEK 2 Compact ANC card,it was not successfully recognized;however,through the identifi-cation by VITEK MS,MALDI Biotyper,Autof ms 1000 and EX-Accuspec,it was all confirmed as A.succinicip-roducens.Additionally,16S rRNA gene sequencing technology also identified it as A.succiniciproducens.CONCLUSIONS Current automated biochemical identification systems are unable to accurately identify A.succi-niciproducens.MALDI-TOF MS and 16S rRNA gene sequencing techniques can reliably confirm A.succinicipro-ducens.Clinical microbiologists should select the appropriate identification method based on their available re-sources.

OBJECTIVE To standardize the strategies for prevention and control of Chikungunya(CHIK)in healthcare in-stitutions so as to reduce the risk of transmission in the institutions.METHODS A working group comprising the ex-perts in hospital infection control,infectious diseases,and microbiology systematically reviewed domestic and international evidence and current guidelines,integrated China's vector ecology and healthcare realities,conducted two rounds of Delphi to achieve expert consensus,and graded the evidence and recommendation strength using the Oxford Centre for Evidence Based Medicine system.RESULTS The consensus issues 18 actionable recommendations on triage,patient mosquito-proof isolation,integrated vector control,protection of susceptible populations,environmental cleaning and disinfection,specimen management,medical textile handling,and outbreak emergency response,with each statement assigned an evi-dence level and recommendation strength.CONCLUSION This consensus is for the first time in China to provide evidence-graded strategies for control of CHIK in healthcare institutions,offering work flow-oriented,implementable guidance for clinicians,laboratorians,and infection-control personnel under different risk scenarios and enhancing the comprehensive coping capacity of the healthcare institutions.

Objective:To explore the clinical features and molecular characteristics of myeloproliferative neoplasms (MPNs) patients with NFE2 gene mutations.Methods:Gene targeted sequencing was used to detect NFE2 gene mutation in 723 patients diagnosed with MPNs who were admitted to Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College between April 2021 and June 2023. The association between NFE2 gene mutations and clinical features and molecular characteristics of MPNs patients were retrospectively analyzed.Results:Among 723 patients with MPNs, NFE2 gene mutations were found in 41 cases (5.7%) . NFE2 gene mutations were predominantly frameshift mutations (44.4%) , followed by nonsense mutations (33.3%) . The median number of mutations in patients with NFE2 gene mutations (4 [2,5]) was higher compared to the group without NFE2 gene mutations (2, [1,3]) ( P<0.001) . NFE2 gene mutations frequently co-occurred with mutations in MPL, ATM, PPM1D, and TET1. NFE2 gene mutations were mostly sub-clonal events, with 80.5% occurring after MPNs driver mutations (JAK2, CALR, or MPL) . NFE2 mutations were correlated with older age [median age: 60 (54, 67) years vs 54 (41, 63) years, P=0.001]. Patients with NFE2 gene mutations had a higher incidence of pre-diagnosis thrombosis (39.0% vs 22.0%, P=0.012) and pre-diagnosis arterial thrombosis (36.6% vs 20.4%, P=0.014) . Using a logistic regression analysis model adjusting for age and comorbidities (including chronic infections, malignancies, and autoimmune diseases) , NFE2 gene mutation was identified as an independent determinant of elevated tumor necrosis factor-alpha (TNF-α) ( OR=2.747, 95% CI: 1.143-6.605, P=0.024) , interferon-gamma (IFN-γ) ( OR=2.689, 95% CI: 1.191-6.076, P=0.017) , IL-10 ( OR=3.219, 95% CI: 1.343-7.717, P=0.009) , IL-12P70 ( OR=3.397, 95% CI:1.003-11.508, P=0.049) , IL-17 ( OR=2.284, 95% CI: 1.017-5.127, P=0.045) . In polycythaemia vera (PV) patients with the NFE2 gene mutation, the proportion of those classified as high-risk is notably higher in both the IWG-PV and mutation-enhanced international prognostic systems for PV (MIPSS-PV) (66.7% vs 25.3% for IWG-PV, P=0.033; 22.2% vs 2.0% for MIPSS-PV, P=0.013) . Similarly, for essential thrombocythaemia (ET) patients, the proportion in the high-risk group of the mutation-enhanced international prognostic systems for ET (MIPSS-ET) is significantly higher (15.4% vs 6.1%, P=0.021) . No statistically significant differences were observed in overall survival or cumulative incidence of thrombosis between NFE2-mutated (38 cases) and non-mutated MPNs patients (671 cases, P>0.05) . Conclusion:NFE2 gene mutations in MPNs were predominantly frameshift mutations. NFE2 gene mutations were correlated with older age, elevated levels of several inflammatory factors (including TNF-α、IFN-γ、IL-10、IL-12P70、IL-17) , and they mostly occurred in late-stage of MPNs.
