AIM To investigate the impact of varying dosages of Supplemented Wendan Decoction on the PI3K/Akt/FOXO1 glycolipid metabolic pathway in 3T3-L1 adipocytes.METHODS The CCK-8 assay was used to determine the concentration of Supplemented Wendan Decoction-medicated serum.The mature adipocytes differentiated from 3T3-L1 preadipocytes after induction were further divided into the blank control group,the model group,the rosiglitazone group(10 mg/L),and the Supplemented Wendan Decoction groups(5％,10％,and 20％),followed by the sample collections after 48 hours of treatment.Oil red O staining quantified lipid accumulation in 3T3-L1 adipocytes;extracellular glucose levels were measured using glucose oxidase(GOD)assay;RT-qPCR analyzed mRNA expressions of IRS-1,PI3K,Akt,GLUT4,IL-6,TNF-α and IL-1β;Western blot assessed protein expressions of INSR,IRS-1,PI3K-p85,Akt,FOXO1 and GLUT4.RESULTS No significant changes in cell viability(P＞0.05)were observed in 3T3-L1 preadipocytes exposed to serum containing supplemented Wendan Decoction at different concentrations for 24,48,or 72 hours.The 3T3-L1 preadipocytes held the capacity to differentiate into mature adipocytes within a 14-day induction period.Compared to the model group,all supplemented Wendan Decoction groups exhibited reduced lipid accumulation in adipocytes and downregulated mRNA expression of IRS-1,IL-6,TNF-α and IL-1β(P＜0.01);the low-dose group demonstrated increased mRNA expressions of PI3K and GLUT4(P＜0.05,P＜0.01),alongside elevated protein expressions of INSR,IRS-1,PI3K-p85,Akt and GLUT4(P＜0.05,P＜0.01);the medium-dose group showed enhanced GLUT4 mRNA expression,and upregulated protein expressions of INSR and FOXO1(P＜0.01).After 24 hours intervention,the high-dose Supplemented Wendan Decoction group exhibited increased glucose consumption in adipocytes(P＜0.01),and elevated protein expression of INSR,Akt and FOXO1(P＜0.05,P＜0.01).CONCLUSION Supplemented Wendan Decoction reduces lipid accumulation in adipocytes,regulates glucose and lipid metabolism,and promotes metabolic homeostasis through PI3K/Akt/FOXO1 signaling pathway.

OBJECTIVE: As an age-related neurodegenerative disease, the prevalence of mild cognitive impairment (MCI) increases with age. Within the framework of traditional Chinese medicine, spleen-kidney deficiency syndrome (SKDS) is recognized as the most frequent MCI subtype. Due to the covert and gradual onset of MCI, in community settings it poses a significant challenge for patients and their families to discern between typical aging and pathological changes. There exists an urgent need to devise a preliminary diagnostic tool designed for community-residing older adults with MCI attributed to SKDS (MCI-SKDS). METHODS: This investigation enrolled 312 elderly individuals diagnosed with MCI, who were randomly distributed into training and test datasets at a 3:1 ratio. Five machine learning methods, including logistic regression (LR), decision tree (DT), naive Bayes (NB), support vector machine (SVM), and gradient boosting (GB), were used to build a diagnostic prediction model for MCI-SKDS. Accuracy, sensitivity, specificity, precision, F1 score, and area under the curve were used to evaluate model performance. Furthermore, the clinical applicability of the model was evaluated through decision curve analysis (DCA). RESULTS: The accuracy, precision, specificity and F1 score of the DT model performed best in the training set (test set), with scores of 0.904 (0.845), 0.875 (0.795), 0.973 (0.875) and 0.973 (0.875). The sensitivity of the training set (test set) of the SVM model performed best among the five models with a score of 0.865 (0.821). The area under the curve of all five models was greater than 0.9 for the training dataset and greater than 0.8 for the test dataset. The DCA of all models showed good clinical application value. The study identified ten indicators that were significant predictors of MCI-SKDS. CONCLUSION The risk prediction index derived from machine learning for the MCI-SKDS prediction model is simple and practical; the model demonstrates good predictive value and clinical applicability, and the DT model had the best performance.

Objective:To construct a clinical early warning model for bladder spasm occurred after transurethral resection of the prostate(TURP)in patients with benign prostatic hyperplasia(BPH)based on LASSO regression.Methods:The clinical data of 139 patients with BPH who underwent TURP treatment in Yellow River Sanmenxia Hospital from January 2022 to June 2024 were prospectively selected,and they were divided into spasm group(39 cases)and non-spasm group(100 cases)according to whether bladder spasm occurred after surgery.The characteristics of bladder spasm occurred after TURP in patients with BPH were statistically analyzed,and the general data between the two groups were compared.LASSO regression was used to screen the characteristic variables related to bladder spasm occurred after TURP,multivariate logistic regression was used to analyze the influencing factors of bladder spasm after TURP.The prediction model of bladder spasm after TURP was constructed,and the receiver operating characteristic(ROC)curve was drawn to evaluate the efficacy of the prediction model.Results:The incidence of bladder spasm after TURP was 28.06％.There were significant differences in age,history of diabetes,operation time,temperature of irrigating fluid,traction tension of urinary catheter,prostate volume and postoperative hospital stay between non-spasm group and spasm group(P＜0.05).LASSO regression showed that operation time,age,traction tension of urinary catheter,temperature of irrigating fluid,history of diabetes were important characteristics of bladder spasm occurred after TURP.Multivariate logistic regression analysis showed that old age,history of diabetes and long operation time were independent risk factors of bladder spasm occurred after TURP(P＜0.05).ROC curve showed that the area under the curve(AUC)of the risk prediction model for bladder spasm occurred after TURP was 0.885(95％CI:0.752-0.921).Conclusions:Old age,history of diabetes and long operation time are independent risk factors of bladder spasm occurred after TURP,the clinical warning model based on LASSO regression has a certain value in predicting the risk for bladder spasm occurred after TURP,which helps to identify high-risk patients early.

Aim To investigating the effects and mech-anisms of chlorogenic acid(CGA)on neutrophil(NEU)function and the formation of neutrophil extra-cellular traps(NETs).Methods NEU was isolated and purified from mouse bone marrow by using density gradient centrifugation method;NEU were cultivated with CGA,and the suitable concentration of CGA with NEU were explored through CCK-8 method;To observ-ing the impact of CGA on the function of NEU,we measured the migration ability of NEU,and the levels of myeloperoxidase(MPO),neutrophil elastase(NE),and matrix metalloproteinase 9(MMP-9);The histone H3 of NETs and the DNA skeleton of NEU were stained with immunofluorescence,and the cell-free DNA(cf-DNA)released by NEU was detected to ob-serve the structure of NETs;In addition,the levels of reactive oxygen species(ROS)were also examined to determine whether CGA affects the production of ROS during the release of NETs from NEU.Results There was a significant inhibitory effect on the activity of NEU at a concentration of 100,200,400 μmol·L-1 of CGA(P＜0.01);When compared with the blank group,the effects of CGA(100,200,400 μmol·L-1)on the migration ability of NEU and the ability to se-crete MPO,NE,and MMP-9 were increased(P＜0.05),the release of histone H3,DNA backbone and cf-DNA was significantly increased(P＜0.01),and the ROS produced by the cells was also significantly in-creased(P＜0.01).And the above effects are concen-tration-dependent within a certain range.Conclusion CGA can enhance the function of NEU and promote the formation of NETs,which may be related to the in-crease of intracellular ROS levels.

Objective:To investigate the association between peripheral immune function status and lung cancer metastasis,and to identify peripheral blood immune biomarkers for'Deficiency of Vital Qi'assessment in lung cancer metastasis.Methods:A retrospective analysis was conducted on peripheral blood immune markers collected before treatment from lung cancer patients admitted into Shanghai Municipal Hospital of Traditional Chinese Medicine,affiliated to Shanghai University of Traditional Chinese Medicine,between March 2023 and April 2025.Patients were categorized into the non-metastatic and the metastatic groups based on the presence of distant metastasis,and the differences in the expressions of immune cells and cytokines between groups were compared.Peripheral blood immune markers with P<0.05 in univariate analysis were incorporated into a multivariate binary logistic regression model to identify independent predictors of lung cancer metastasis.Results:A total of 193 lung cancer patients were included(101 in the non-metastatic group and 92 in the metastatic group).There were no statistically significant differences between the two groups in terms of gender,age,smoking history,drinking history,or pathological type(all P>0.05).Univariate analysis revealed significant differences in multiple immune markers between the non-metastatic and metastatic groups(all P<0.05),including:lymphocyte count,CD3+,CD4+,and CD8+T,CD19+B cells,absolute counts of CD3-CD16+CD56+NK cells,percentages of Treg cells,CD8+CD28+Treg cells,G-MDSC,and CD3-CD16+CD56+dim NK cells,and levels of cytokine IL-1β,IL-6,and IL-10.Binary logistic regression analysis of differential indicators suggested that the percentage of Treg cells and CD8+CD28+Treg cells in peripheral blood were independent predictors of distant metastasis in lung cancer(OR=1.193,95%CI[1.047,1.36],P<0.01;OR=0.978,95%CI[0.957,0.999],P<0.05).Conclusion:Peripheral blood immune dysfunction is the biological basis for'qi deficiency'in lung cancer metastasis.This study quantitatively demonstrates the correlation between peripheral immune function status and lung cancer metastasis,providing empirical evidence for the theories of'qi deficiency and hidden toxicity'and'metastatic state of tumors'.

Objective:To evaluate the changes in left ventricular structure and function in pregnant women with different severities of hypertensive disorders of pregnancy（HDP）using conventional echocardiographic parameters，strain，and tissue-tracking mitral annulus displacement（TMAD）parameters，and to validate and compare the application value of strain and TMAD parameters.Methods:A total of 148 singleton pregnant women with HDP and 100 healthy pregnant women（HP group）who attended the Third Affiliated Hospital of Zhengzhou University from October 2023 to July 2024 were selected. Conventional echocardiographic parameters，strain，and TMAD parameters were collected. Based on the severity of the disease，HDP patients were divided into the gestational hypertension group（GH group， n=49），non-severe preeclampsia group（NSPE group， n=35），and severe preeclampsia group（SPE group， n=64）. The differences in various parameters between the HP，GH，NSPE，and SPE groups were compared. The correlation between the displacement ratio of the midpoint of the mitral valve annulus in the apical 4-chamber（AP4 Midpt%），the displacement ratio of the midpoint of the mitral valve annulus in the apical 2-chamber（AP2 Midpt%）and left ventricular global longitudinal strain（LVGLS）were analyzed，and ROC curves were plotted to analyze and compare the diagnostic efficacies of LVGLS，AP4 Midpt% and AP2 Midpt% for left ventricular function changes in HDP pregnant women. Results:① The analysis revealed no statistically significant differences in maternal age and height between the HP group and the HDP subgroups（all P>0.05）. In contrast，statistically significant differences were observed in gestational age，systolic blood pressure，diastolic blood pressure，body mass index，and body surface area（all P<0.05）. Additionally，significant differences were noted in left ventricular mass，left ventricular interventricular septum thickness at end-diastole，left ventricular posterior wall thickness at end-diastole，left ventricular end-diastolic dimension，left ventricular end-systolic dimension，left ventricular end-diastolic volume，left ventricular end-systolic volume，and stroke volume between the HP group and the HDP subgroups（all P<0.05），while the difference in left ventricular ejection fraction was not statistically significant（ P>0.05）. ② Significant differences were identified in strain and TMAD parameters between the HP group and the HDP subgroups（all P<0.05），with LVGLS，AP4 Midpt% and AP2 Midpt% exhibited the largest effect sizes（ η p2=0.457，0.453，0.351）. A progressive decline in strain and TMAD parameters was observed as the severity of HDP increased. ③ There were strong positive correlations between AP4 Midpt%，AP2 Midpt% and LVGLS（ r=0.752，0.747；all P<0.001）. ④ LVGLS，AP4 Midpt% and AP2 Midpt% all demonstrated significant diagnostic efficacies for changes in left ventricular function in HDP（AUC=0.840，0.847，0.791），and the differences in AUC among the 3 curves were not statistically significant（all P>0.05）.⑤ The success rate of collecting TMAD parameters was significantly higher than that of strain parameters（99.24% vs. 93.58%， P<0.001）. Conclusions:As the severity of the disease worsens，the changes of left ventricular structure and function in pregnant women with HDP become more and more significant. Both strain and TMAD parameters can early and sensitively identify the subclinical damage of left ventricular systolic function in HDP pregnant women，and both of them have the same diagnostic value. TMAD parameters can be used as a reliable substitute parameter of LVGLS in HDP pregnant women.

Objective To establish a high-throughput non-targeted screening and prioritization method for emerging pollutants(EPs)in sewage using direct injection high-resolution mass spectrometry(HRMS).Methods The sewage samples were filtered by membrane filter and directly subjected to the liquid chromatography-time-of-flight mass spectrometer based on a method modified from our previous study.A C18 chromatographic column was applied for a gradient elution separation,and accurate mass and mass spectral fragment information were obtained through the MS full scan mode and MS/MS DIA data collection mode.After peak detection and alignment,the features from the raw data through open source software MZmine 3,and then high-throughput screening strategies such as MassBank and PubChem databases were used for compound annotation.Finally,the candidate features were confirmed with chemical standards by compared their retention time and mass spectrum fragmentation ion peaks.Results 13 EPs were identified,including 7 industrial chemicals,4 pharmaceuticals,1 pesticide and 1 metabolite.High detection rates were observed for metformin(86.2％),2-hydroxybenzothiazole(79.3％),1,2-benzisothiazole-3-one(72.4％),and 1,2-benzisothiazole-3-one(72.4％).The quantitative concentration range of EPs was 1.37～19.05 ng/mL,with the high concentrations observed for melamine(19.05 ng/mL)and furosemide(18.49 ng/mL).Ecological risk assessment identified 1,2-benzisothiazol-3-one,4-aminoacetophenone,creatinine,2-hydroxybenzothiazole,and furosemide as key pollutants.Conclusion This direct injection coupled with HRMS workflow enables efficient non-targeted screening and prioritization of emerging EPs in sewage samples,highlighting five ecotoxicologically critical EPs.The methodology enhances environmental monitoring capabilities and provide critical technical support for interdisciplinary research such as environmental forensics and health risk assessment.
