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.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

ObjectiveThis study explored the risk factors for malignant risks of pulmonary nodules based on clinical data，constructed an integrated traditional Chinese and Western medicine model for predicting malignant risks of pulmonary nodules， and visualized the prediction results by using a nomogram. MethodsBased on a cross-sectional survey study design，patients with pulmonary nodules who were hospitalized in the Department of Respiratory and Cardiothoracic Surgery of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2023 to January 2024 were included. The dataset was randomly divided into a training set and a validation set according to 7∶3. In the training set，predictive factors were selected through univariate Logistic regression analysis and Least Absolute Shrinkage and Selection Operator （LASSO） regression analysis，and Logistic regression models were built. The discriminative ability，calibration，and clinical decision-making curves of the Western medicine model and the integrated traditional Chinese and Western medicine prediction model were compared to select the optimal model，which was then visualized in a nomogram. ResultsThis study included a total of 366 patients，and they were divided into a training set （258 cases） and a validation set （108 cases）. Seven predictive factors were considered including age，preference for fatty and greasy foods，history of environmental or occupational exposure，Qi deficiency，Yang deficiency，nodule density，and nodule diameter. A Logistic regression model was constructed. A Western medicine model，defined as model1，was created using only age，history of environmental or occupational exposure，nodule density，and nodule diameter as predictive factors. In addition，an integrated traditional Chinese and Western medicine model，defined as model2，was created by adding preference for fatty and greasy foods， Qi deficiency，and Yang deficiency as predictive factors. Model2 demonstrated better predictive performance in both the training and validation sets. Its accuracy in training set was 0.740，with precision of 0.825， recall of 0.829， F1 score of 0.827， the area under the curve （AUC）of 0.865 （95% confidence interval （CI）：0.815-0.915）， and a Brier score of 0.122. The accuracy in validation set was 0.731， with precision of 0.776， recall of 0.831， F1 score of 0.803， AUC of 0.852 （95%CI：0.776-0.927）， and a Brier score of 0.149. The calibration curve and decision-making curve analysis showed that this model exhibited good consistency and clinical utility in prediction. The equation for the malignant probability of pulmonary nodules was defined as p=eY/(1+eY)，where Y=-4.187+0.022×（age）+1.079×（history of environmental or occupational exposure）+0.718×（preference for fatty and greasy foods）+ 1.403×（Qi deficiency）+0.732×（Yang deficiency）+0.349×（pure ground glass density nodules）+1.304×（partially solid density nodules）+0.148×（nodule diameter）. A nomogram was used for intuitive representation. ConclusionThis study develops a comprehensive assessment model for the malignant risk of pulmonary nodules， which integrates factors from traditional Chinese medicine and Western medicine. Embedding traditional Chinese medicine elements in the prediction model allows for a multidimensional assessment of relevant risk factors for nodule malignancy. This demonstrates good diagnostic performance and provides a reference for early identification of lung cancer.

Objectives:To analyze the risk factors of atrial fibrillation in patients with non-obstructive hypertrophic cardiomyopathy(NOHCM)and explore the relationship between left ventricular/atrial volume and atrial fibrillation.Methods:Consecutive NOHCM patients admitted at Fuwai Hospital from January 2023 to January 2024 with complete clinical data,satisfactory echocardiography imaging data were included in this analysis,patients were divided into atrial fibrillation group(n=28)and non-atrial fibrillation group(n=57).Left-sided volumetric and functional parameters were measured by one-beat real-time full-volume three-dimensional echocardiography,including left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular ejection fraction(LVEF),left atrial volume(LAV).The left ventricular end-diastolic volume(LVEDVi)index,left ventricular end-systolic volume index(LVESVi)and left atrial volume index(LAVi)were calculated.Other echocardiographic parameters including interventricular septum(IVSmax)thickness,left ventricular posterior wall thickness(LVPW),and left atrial diameter(LAD)were routinely measured.Mitral valve forward flow spectrum,tissue Doppler,tricuspid regurgitation velocity,and left atrial size were used to evaluate the left ventricular diastolic function of patients,and diastolic dysfunction was classified into grade I,II,and III.Multivariate logistic regression was used to analyze the influencing factors of atrial fibrillation in patients with non-obstructive hypertrophic cardiomyopathy Results:Compared with the non-atrial fibrillation group,LVEDV([143.8±26.7]ml vs.[117.1±21.9]ml)and LVEDVi([79.4±11.9]ml/m2 vs.[64.2±10.6]ml/m2)were smaller in atrial fibrillation group(both P<0.001).Compared with the non-atrial fibrillation group,LAD([40.2±4.7]mm vs.[48.6±4.8]mm)and LAVi([37.3±8.9]ml/m2 vs.[64.4±17.1]ml/m2)were lager in atrial fibrillation group(both P<0.001).Compared with the non-atrial fibrillation group,the proportion of NYHA functional classification≥Ⅲ was higher(15.8%vs.50.0%,P<0.001),LVEF was lower([61.5±5.5]%vs.[57.6±5.0]%,P=0.002),and proportion of severe diastolic dysfunction was higher in atrial fibrillation group(P<0.001).Logistic regression analysis showed that the factors associated with atrial fibrillation in NOHCM patients were LVEDVi(OR=0.744,95%CI:0.575-0.962,P=0.024)and LAVi(OR=1.602,95%CI:1.032-2.486,P=0.036).Conclusions:LVEDVi and LAVi are related factors for atrial fibrillation in patients with non-obstructive hypertrophic cardiomyopathy.LVEDVi is negatively,while LAVi is positively associated with the occurrence of atrial fibrillation in NOHCM patients.

Objective::This study aimed to assess the impact of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor treatment immediately after percutaneous coronary intervention (PCI) on the myocardial salvage index (MSI) in patients with anterior ST-segment elevation myocardial infarction (STEMI) 5-10 d after the procedure.Methods::The early PCSK9 inhibitor thERapy Following pErcutaneous Coronary inTervention (PERFECT) trial is a prospective randomized controlled trial. From January 2021 to December 2023, 32 patients with anterior STEMI from Tongren Hospital, Shanghai Jiao Tong University School of Medicine, Songjiang Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, and Shanghai Tenth People’s Hospital were enrolled in the PERFECT trial. Patients were randomly assigned in a 1∶1 ratio to the PCSK9 inhibitor group ( n = 16) or the control group ( n = 16), and their baseline data were collected. Patients in the PCSK9 inhibitor group (ie, alirocumab group) received a subcutaneous injection of PCSK9 inhibitor (alirocumab, 75 mg) immediately after PCI based on conventional treatment. In the control group, patients received only conventional treatment. The primary endpoint was the MSI measured by cardiovascular magnetic resonance 5-10 d after PCI. The secondary endpoints included the left ventricular ejection fraction measured by cardiovascular magnetic resonance 5-10 d after PCI and the time to peak of creatine kinase isoenzyme-MB and high-sensitivity cardiac troponin T. Safety endpoints included any clinical adverse events that occurred during the 6-month follow-up period. Results::Baseline data during admission showed no intergroup significance. No significant difference in MSI (55.54% ± 14.80% vs. 44.72% ± 15.42%, P = 0.056) and left ventricular ejection fraction (51.24% ± 8.91% vs. 44.99% ± 8.84%, P = 0.060) was observed. Additional, there was no significant difference in the time to peak of creatine kinase isoenzyme-MB ((12.97 ± 5.67) h vs. (14.31 ± 7.04) h, P = 0.557) and high-sensitivity cardiac troponin T ((21.03 ± 12.46) h vs. (21.44 ± 9.99) h, P = 0.920) between the 2 groups. During the 6-month follow-up period, only 1 patient in the PCSK9 inhibitor group developed cerebral hemorrhage 6 months after PCI. Conclusions::Early treatment with alirocumab did not exhibit a significant increase in MSI at 5-10 d in patients with anterior STEMI. Larger trials are necessary to evaluate the impact of early administration of PCSK9 inhibitors after myocardial infarction.

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.

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.
