This paper introduces a real-world cohort research model for community-acquired pneumonia （CAP） based on the Jiangsu Traditional Chinese Medicine （TCM） Dominant Diseases Diagnosis and Treatment Data Platform. Firstly， data cleaning is performed by standardizing diagnosis， symptoms， treatment and imaging， intelligently extracting unstructured information， and cleaning and constructing a standardized database. Secondly， for cohort establishment， CAP patients across the province are screened in accordance with CAP diagnostic criteria to build a high-quality disease-specific cohort. Lastly， in terms of protocol design， the characteristics of TCM research and the CAP disease profile are considered to determine appropriate inclusion and exclusion criteria， estimate sample size， define interventions， outcomes and economic evaluations， providing a reference for real-world TCM research on CAP.

Objective:To investigate the relationship between serum soluble thrombomodulin(sTM),soluble interleukin-2 receptor(sIL-2R)and short-term prognosis in patients with acute exacerbation chronic obstructive pulmonary disease(AECOPD)combine with type Ⅱ respiratory failure(RF).Methods:251 patients with AECOPD combine with type Ⅱ RF who were admitted to our hospital from April 2021 to April 2024 were selected,the serum sTM and sIL-2R levels of all patients were detected,and the prognosis of 10 d after admission of patients was counted,patients were divided into death group(n=40)and survival group(n=211)according to different prognosis.Influencing factors were analyzed by multivariate logistic regression analysis,predictive value was analyzed by receiver operating characteristic(ROC)curve.Results:Serum sTM and sIL-2R levels in death group were higher than those in survival group(P＜0.05).long course of chronic obstructive pulmonary disease(COPD)and severe RF,high sTM and high sIL-2R were risk factors for death of 10 d after admission of patients with AECOPD combine with type Ⅱ RF(P＜0.05).The area under the curve(AUC)of serum sTM and sIL-2R detection in predicting death of 10 d after admission of patients with AECOPD combine with type Ⅱ RF was 0.801 and 0.810,respectively,the AUC of joint detection of serum sTM and sIL-2R was 0.859,which was higher than that of each index alone.Conclusion:Serum sTM and sIL-2R levels in patients with AECOPD combine with type Ⅱ RF are significantly increase,which are relate to the occurrence of poor prognosis of 10 d after admission,serum sTM and sIL-2R are expect to be used as auxiliary predictive markers for short-term prognosis of patients with AECOPD combine with type Ⅱ RF,and long course of COPD and severe RF,APACHE Ⅱ score are the influencing factors of poor prognosis in patients with AECOPD combine with type Ⅱ RF.

Objective To establish a rat model of venous thrombosis in a plateau hypobaric hypoxic environment and to investigate the effect of this environment on venous thrombosis.Methods A total of 144 healthy male SD rats were assigned randomly to four groups(n=36 rats per group):a plains sham operation(A)group,plains operation(B)group,plateau altitude 6000 m+sham operation(C)group,and plateau altitude 6000 m+surgery(D)group.Rats in A and B groups were maintained in a plains normoxic environment,while rats in C and D groups C and D were subjected to a plateau environment.Rats in the surgical groups underwent quantitative constriction to incompletely obstruct the inferior vena cava blood flow.Each group was further divided into subgroups based on time:1,3,5,7,14,and 21 d(n=6 rats per group).Regular vascular ultrasound monitoring was conducted,and blood samples were taken for whole blood viscosity testing and the assessment of inflammatory indicators,including endothelin-1(ET-1),interleukin-6(IL-6)and tissue factor(TF).Coagulation function was evaluated through the activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB)and D-dimer.After the observation period,the experimental animals were sacrificed and the limbs were removed.Thrombus samples were stained with hematoxylin/eosin(HE),and the thrombus wet mass was measured.Results The thrombosis incidence was significantly higher in the plateau D group than in B group,accompanied by a marked increase in blood viscosity and hematocrit(P＜0.01).Additionally,levels of ET-1,IL-6,and TF were significantly elevated(P＜0.05),indicating a coagulation disorder.Conclusions A plateau hypoxic environment model can be successfully simulated by quantitative coarctation of the inferior vena cava,combined with a specialized environmental chamber.The findings of this study suggest that a plateau hypoxic environment promotes venous thrombosis.

Blood from a case of group B epidemic cerebrospinal meningitis identified in February 2024 in Ganzhou City,Jiangxi Province,and throat swabs from close contacts were collected for isolation and culture.The isolates were subjected to serogrouping,drug sensitivity testing,and whole genome sequencing and analysis,to provide a basis for epidemiological inves-tigation and clinical drug use.One strain of Neisseria meningitidis was isolated from the blood of the case and denoted group B.The MLST type was ST-7962,with no clonal group attribution.The phylogenetic tree showed that it was genetically close to the 1977 Shanghai carrier isolate(id-52231).Drug sensitivity results indicated that the strain was sensitive to 8 drugs:azithro-mycin,cefotaxime,minocycline,ceftriaxone,chloramphenicol,meropenem,rifampicin,and benzylpenicillin;resistant to cot-rimoxazole,levofloxacin,and ciprofloxacin;and showed an intermediate response to penicillin.This report describes the first case of ST-7962 group B meningoencephalitis found in Jiangxi Province.Monitoring of Neisseria meningitidis carriage,drug re-sistance,and molecular characteristics of strains in the healthy population in this region should be strengthened,to provide la-boratory support for the clinical use of medications,traceability,and control of the pathogen underlying meningoencephalitis infection.

Contrast-free percutaneous coronary intervention demonstrates significant value in reducing contrast-associated risks.This article reports a case of a patient with iodine contrast allergy and complex coronary artery disease(involving the left main stem,left anterior descending artery,and diagonal branch),who successfully underwent contrast-free percutaneous coronary intervention(PCI)through the integration of CT angiography(CCTA),intravascular ultrasound(IVUS),and fractional flow reserve(FFR)technology.Preoperative CCTA delineated the anatomy and planned the procedural approach.Intraoperatively,IVUS assessed plaque burden and vascular remodeling,precisely guiding stent selection and positioning.FFR was combined to evaluate the functional significance of the left main stem lesion and the ischemic significance of the specific stenosis in the left anterior descending artery.Post-procedural assessment evaluated stent result and the degree of flow limitation in the diagonal branch.Through"structure-function"dual optimization,revascularization of the left anterior descending artery was achieved using a single-stent strategy,avoiding intervention on the left main stem.This case confirms that multi-modality imaging techniques can safely manage complex lesions,significantly reduce contrast volume,and are suitable for high-risk patients with allergies or renal insufficiency.Future efforts should focus on standardizing technical protocols and accumulating evidence-based evidence to facilitate the clinical implementation of contrast-free interventions.

Objective To explore the relationship between frontal alpha asymmetry(FAA)assessed by electroencephalogram(EEG)and emotion dysregulation(ED)in children with attention deficit hyperactivity disorder(ADHD).Methods Children with ADHD admitted to Fuyang Women and Children's Hospital from September 2021 to December 2024 were prospectively enrolled(n=104).Based on the Achenbach Child Behavior Checklist(CBCL),participants were classified into an ED group(sum of three subscales<180;n=41)and a non-ED group(sum≥180;n=63).Clinical data were collected,and the Chinese ADHD SNAP-IV parent version and the Weiss Functional Impairment Rating Scale-Parent Report were used.FAA was measured by EEG.Correlations between FAA in different regions and CBCL score were analyzed,and the predictive value of FAA for ED was evaluated with multivariable logistic regression and receiver operating characteristic curves.Results Compared with the non-ED group,the ED group had a higher proportion of the predominantly inattentive ADHD subtype,higher SNAP-IV total score,higher Weiss Functional Impairment Rating Scale-Parent Report total score,and higher FP1/FP2-FAA and C3/C4-FAA(P<0.05).FP1/FP2-FAA and C3/C4-FAA were negatively correlated with CBCL score(P<0.05).The multivariable logistic regression analysis showed that FP1/FP2-FAA and C3/C4-FAA were closely associated with ED in children with ADHD(P<0.05).The areas under the curve for predicting ED using FP1/FP2-FAA,C3/C4-FAA,and their combination were 0.827,0.685,and 0.917,respectively(P<0.05),and the combined prediction had a higher area under the curve than either single marker(P<0.05).The FP1/FP2 FAA value in hyperactive-impulsive ADHD was lower than in combined-type ADHD and predominantly inattentive ADHD(P<0.05).Conclusions FP1/FP2-FAA and C3/C4-FAA are reliable neural markers of emotion dysregulation in children with ADHD,and their combination shows superior predictive performance.ADHD subtypes show distinct patterns of FAA-functional impairment associations.
