ObjectiveTo investigate whether visceral fat area （VFA） is an independent risk factor for significant liver fibrosis in patients with nonalcoholic fatty liver disease （NAFLD） based on clinical data， and to establish an effective diagnostic model. MethodsA total of 222 NAFLD patients who attended Department of Hepatology， Guangdong Provincial Hospital of Traditional Chinese Medicine， from January 2021 to April 2025 were enrolled， and according to liver stiffness measurement （≥8 kPa or not）， they were divided into significant fibrosis group and non-significant fibrosis group. Propensity score matching （PSM） was performed at a ratio of 1∶1 to balance the baseline data between the two groups. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups； the chi-square test was used for comparison of categorical data between groups. A Spearman correlation analysis was used to determine the correlation of VFA and other indicators with significant liver fibrosis； univariate and multivariate logistic regression analyses were used to identify whether VFA was an independent risk factor for significant liver fibrosis in NAFLD patients， and the receiver operating characteristic （ROC） curve was plotted to assess the predictive performance of related indicators. ResultsA total of 45 patients with significant liver fibrosis and 177 patients without significant liver fibrosis were enrolled， and after PSM， 90 patients （45 pairs） were finally included in analysis. Compared with the non-significant fibrosis group， the significant fibrosis group had significantly higher levels of body mass index （BMI）， fasting blood glucose （FBG）， glycated hemoglobin （HbA1c）， uric acid （UA）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， gamma-glutamyl transpeptidase （GGT）， controlled attenuation parameter （CAP）， and VFA， as well as a significantly higher proportion of patients with visceral fat obesity or three or more metabolic risk factors （all P<0.05）. VFA， BMI， AST， and HbA1c were strongly correlated with significant liver fibrosis （all r>0.5， all P <0.05）， and ALT， GGT， UA， FBG， and CAP were significantly positively correlated with significant liver fibrosis （r=0.3　—　0.5， all P<0.05）. VFA （odds ratio ［OR］=1.040， 95% confidence interval ［CI］： 1.018　—　1.062， P<0.05）， FBG （OR=2.372， 95%CI： 1.199　—　4.691， P<0.05）， and AST （OR=1.032， 95%CI： 1.003　—　1.058， P<0.05） were independent risk factors for significant liver fibrosis in NAFLD patients. The new diagnostic model based on VFA， FBG， and AST （with an area under the ROC curve ［AUC］ of 0.907） had a significantly better performance than aspartate aminotransferase-to-platelet ratio index （AUC=0.834）， fibrosis-4 （AUC=0.660）， triglyceride-glucose index （AUC=0.656）， and NAFLD fibrosis score （AUC=0.768） in predicting significant liver fibrosis in NAFLD patients （all P<0.05）. ConclusionVFA is an independent risk factor for significant liver fibrosis in NAFLD patients， and the noninvasive diagnostic model based on VFA， FBG， and AST can effectively predict the onset of significant liver fibrosis in NAFLD patients.

Objective:To explore the predictive value of procalcitonin-to-albumin ratio (PAR) in the short-term prognosis of sequential treatment with butylphthalide for acute cerebral infarction (ACI) after interventional surgery.Methods:The clinical data of ACI patients admitted to 970th Hospital of the Joint Logistics Support Force of the People′s Liberation Army of China from January 2020 to June 2022 were retrospectively included. According to the prognosis of sequential treatment of butylphthalide after interventional therapy, 80 patients with poor prognosis were included in the poor group, and 80 patients with good prognosis were included in the good group. The detection data of procalcitonin, albumin and other laboratory indexes of the two groups of patients on admission were collected, the PAR value was calculated, and the predictive value of PAR on the short-term prognosis of butylphthalide sequential therapy after ACI intervention was analyzed.Results:The levels of procalcitonin (PCT), PAR, D-dimer (D-D), and low density lipoprotein cholesterol (LDL-C) in the poor group were higher than those in the good group: (24.74 ± 5.37) ng/L vs. (20.96 ± 4.11) ng/L, 0.91 ± 0.35 vs. 0.62 ± 0.19, (0.75 ± 0.22) mg/L vs. (0.56 ± 0.17) mg/L, (3.28 ± 0.43) mmol/L vs. (3.03 ± 0.45) mmol/L, while the levels of albumin (ALB) were lower than those in the good group: (29.43 ± 4.25) g/L vs. (33.71 ± 4.53) g/L, with a statistical significant difference ( P<0.05). Multivariate Logistic regression analysis showed that PCT, ALB, PAR, D-D, and LDL-C were all factors influencing the short-term prognosis of sequential treatment with butylphthalide after ACI intervention ( P<0.05). The results of receiver operating characteristic curve (ROC) showed that PCT, ALB, PAR, D-D and LDL-C had certain predictive value for the short-term prognosis of butylphthalide sequential therapy after ACI intervention, and PAR had the best predictive value. Conclusions:PAR is an influential factor for the sequential short-term prognosis of butylphthalide after ACI intervention, and it has certain predictive value for the short-term prognosis of patients.

Objective:To analyze the assessment value of the quantitative parameters of coronary computed tomography angiography(CCTA)combined with QRS wave complex of electrocardiogram(ECG)for grading of cardiac function in patients with coronary heart disease(CHD).Methods:Eighty CHD patients admitted to Beijing Rehabilitation Hospital,Capital Medical University between January 2023 and December 2024 were selected.The grading of cardiac function of CHD patients were assessed according to the standard of New York Heart Association(NYHA).All patients underwent CCTA and ECG upon admission.CCTA quantitative parameters and QRS wave complex duration were recorded and compared among patients with different grades of cardiac function.The correlation between CCTA quantitative parameters[non-calcified plaque volume(NCPV),calcified plaque volume(CPV),total plaque volume(TPV),vessel volume,reconstruction index],QRS wave complex duration,and grading of cardiac function of CHD patient was analyzed.The area under curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the value of each parameter and QRS wave complex duration in assessing CHD patients whose cardiac function grade was≥III grade.Results:In the 80 CHD patients,NYHA grades were distributed as follows:11 cases were grade I,and 23 cases were grade II,and 27 cases were grade III,and 19 cases were grade IV.The NCPV,CPV,TPV,reconstruction index,and QRS wave complex duration of patients at grade III and grade IV were higher than those of patients at grade I-grade II,and the differences were significant(F=17.401,37.077,12.297,7.087,11.148,P<0.05).Furthermore,patients at grade IV showed higher values in all parameters than those of patients at grade III.The NCPV,CPV,TPV,reconstruction index(t=3.486,4.315,3.444,2.068,2.600,P<0.05),and QRS wave complex duration of CCTA parameters showed positive correlations with cardiac function grading in CHD patient(r=0.464,0.548,0.346,0.287,0.373,P<0.05).ROC curve analysis revealed that the AUC values of alone NCPV,CPV,TPV,reconstruction index,QRS wave complex duration of CCTA parameters,and the combination of these indicators were respectively 0.793,0.843,0.723,0.748,and 0.737 in assessing CHD patients whose cardiac function grade was≥III,which indicated that these indicators had a certain assessment value,and the combined detection can improve the AUC value and sensitivity.Conclusion:The combination of CCTA parameters(NCPV,CPV,TPV,reconstruction index)and QRS wave complex duration can improve the assessment value for CHD patients whose grade of cardiac function is≥grade III.

Pregnancy with chronic kidney disease (CKD), particularly in stages 4-5, carries high risks of adverse outcomes including maternal renal failure, preeclampsia/eclampsia, fetal growth restriction, and preterm birth. This report described a 26-year-old woman with congenital solitary kidney, polycystic ovaries, and uterine septum due to PAX2 gene variant, complicated by CKD stage 4. Through multidisciplinary team precision management and individualized treatment strategies, including timely initiation of dialysis, the patient successfully maintained pregnancy until 34 +1 weeks and delivered a female infant via cesarean section. This case summarizes key management experiences for end-stage renal disease in pregnancy, highlighting early risk assessment, precise nutritional management, hemodialysis protocol optimization, and the crucial role of multidisciplinary collaboration, providing valuable references for managing CKD-complicated pregnancies.

Objective To investigate the correlation between serum homeodomain interacting protein ki-nase 2(HIPK2),annexin A5(ANXA5)and coronary stenosis and prognosis in patients with acute myocardial infarction(AMI).Methods A total of 277 AMI patients who received interventional treatment in this hospi-tal from January 2021 to July 2023 were selected as the AMI group,and another 140 cases with normal or very mild stenosis in coronary angiography during the same period were selected as the control group.According to the degree of coronary artery stenosis(Gensini score),the AMI patients were divided into mild coronary arter-y stenosis group(86 cases),moderate coronary artery disease group(111 cases)and severe coronary artery disease group(80 cases).According to the prognosis,they were divided into poor prognosis group(80 cases)and good prognosis group(197 cases).Enzyme-linked immunosorbent assay was used to detect the serum HIPK2 and ANXA5 levels.Spearman correlation analysis was used to analyze the correlation between serum HIPK2 and ANXA5 levels and Gensini score in patients with AMI.Multivariate unconditional Logistic regres-sion was used to determine the relationship between serum HIPK2 and ANXA5 levels and prognosis of AMI patients.Receiver operating characteristic(ROC)curve was used to analyze the predictive efficiency of serum HIPK2 and ANXA5 levels on prognosis of AMI patients.Results Compared with the control group,the ser-um HIPK2 level in the AMI group increased and the ANXA5 level decreased,and the differences were statisti-cally significant(P＜0.05).The serum HIPK2 levels in the mild coronary artery stenosis group,moderate coronary artery stenosis group and severe coronary artery stenosis group increased successively,while the ANXA5 levels decreased successively,and the differences were statistically significant(P＜0.05).Gensini score was positively correlated with serum HIPK2 level and negatively correlated with serum ANXA5 level in AMI patients(P＜0.05).The Gensini score of AMI patients was positively correlated with the serum HIPK2 level(r=0.785,P＜0.05),and negatively correlated with the serum ANXA5 level(r=-0.798,P＜0.05).Compared with the good prognosis group,the serum HIPK2 level in the poor prognosis group increased(P＜0.05),and the ANXA5 level decreased(P＜0.05).After adjusting for confounding factors,high HIPK2 was an independent risk factor for poor prognosis in AMI patients(P＜0.05),and high ANXA5 was an independ-ent protective factor(P＜0.05).The area under the curve of the combined prediction of serum HIPK2 and ANXA5 levels for the prognosis of AMI patients was 0.875,which was greater than 0.778 and 0.784 predic-ted by serum HIPK2 and ANXA5 levels alone(P＜0.05).Conclusion The serum HIPK2 level is increased and the ANXA5 level is decreased in patients with AMI,which is related to the aggravation of coronary steno-sis and the poor prognosis.The combination of serum HIPK2 and ANXA5 levels is more effective in predic-ting the prognosis of patients with AMI.

Objective:To systematically elucidate the molecular mechanism of hesperetin in the treatment of heart failure by network pharmacology, molecular docking, and molecular dynamics, and to clarify its key targets and pathway regulatory networks.Methods:Potential targets of hesperetin were retrieved from the PubChem, Pharmmapper, SwissTargetPrediction, and Similarity ensemble approach databases. Heart failure-related targets were obtained from the OMIM, GeneCards, and TTD databases. Intersection targets were identified using Venny 2.1. A protein-protein interaction (PPI) network of potential targets was constructed using the STRING database and Cytoscape 3.9.0 software. Gene ontology (GO) functional and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analyses of key targets were performed using the Metascape database. Molecular docking was carried out using Autodock vina1.1.2. GROMACS (2024.03) was employed to conduct a 100 ns molecular dynamics simulation on the optimal affinity complex. The thermodynamic stability of the candidate complex during simulation was evaluated by analyzing the root mean square deviation (RMSD), root mean square fluctuation (RMSF), radius of gyration (Rg), and binding free energy. Data were analyzed by an independent sample t test or one-way analysis of variance. Results:A total of 356 related targets of hesperetin and 2 923 related targets of heart failure were screened, with 152 intersection targets identified as potential targets for hesperetin intervention in heart failure. PPI network topological analysis revealed key targets for hesperetin intervention in heart failure, including insulin-like growth factor 1, estrogen receptor 1 (ER1), cysteine aspartic acid specific protease-3, sarcoma proto-oncogene, matrix metalloproteinase 9 (MMP9), MMP2, Janus kinase 2 (JAK2), albumin, heat shock protein 90 alpha family class A member 1, epidermal growth factor receptor, and B-cell lymphoma-2 (Bcl-2). GO functional enrichment analysis indicated that biological processes were mainly enriched in response to hormone stimulation, positive regulation of cell migration, gland development, response to nutritional levels, regulation of system processes, and response to trauma. Molecular functions were primarily enriched in phosphotransferase activity, nuclear receptor activity, endopeptidase activity, kinase binding, heme binding, hormone binding and protease binding. Cellular components were mainly enriched in membrane-related structures such as vesicle cavity, membrane raft, vacuole cavity, receptor complex and extracellular matrix containing collagen. KEGG pathway enrichment analysis showed that these key targets were significantly enriched in lipid and atherosclerosis, diabetic cardiomyopathy, and the hypoxia-inducible factor-1 signaling pathway. Molecular docking results indicated that the binding energy of hesperetin to MMP9 (?46.442 kJ/mol) was significantly lower than that to other key targets. Molecular dynamics simulations revealed that the hesperetin-MMP9 complex maintained structural stability, with an average RMSD of 1.60 ?. The average RMSF values of MMP9 residues (0.83 ?) and ligand atoms (0.68 ?) indicated stable protein conformation and ligand-binding states. The Rg values of MMP9 [(15.04±0.60) ?] and hesperetin [(4.19±0.35) ?] showed minimal fluctuations, further supporting structural compactness. The total binding free energy of the hesperetin-MMP9 complex during the 100 ns simulation was (?142.3±6.3) kJ/mol, with minimal energy fluctuations, confirming that the complex remained structurally stable without significant energy transition throughout the simulation.Conclusions:Hesperetin may bind effectively to targets such as MMP9, JAK2, Bcl-2, and ER1, and form a stable complex with MMP9. It is suggested to influence biological processes related to lipids and signaling pathways such as atherosclerosis, diabetic cardiomyopathy, and hypoxia-inducible factor-1, thereby playing a role in heart failure intervention.

OBJECTIVE: To observe the characteristics of changes in non-invasive hemodynamic parameters in neonates with septic shock so as to provide clinical reference for diagnosis and treatment. METHODS: A observational study was conducted. The neonates with sepsis complicated with septic shock or not admitted to neonatal intensive care unit (NICU) of the First Affiliated Hospital of Shantou University Medical College were enrolled as the study subjects, who were divided into preterm infant (< 37 weeks) and full-term infant (≥ 37 weeks) according to the gestational age. Healthy full-term infants and hemodynamically stable preterm infants transferring to NICU after birth were enrolled as controls. Electronic cardiometry (EC) was used to measure hemodynamic parameters, including heart rate (HR), mean arterial pressure (MAP), stroke volume (SV), stroke volume index (SVI), cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR) and systemic vascular resistance index (SVRI), before treatment in the septic shock group, at the time of diagnosis of sepsis in the sepsis without shock group, and before the discharge from the obstetric department or on the day of transferring to NICU in the control group. RESULTS: Finally, 113 neonates with complete data and parental consent for non-invasive hemodynamic monitoring were enrolled, including 32 cases in the septic shock group, 25 cases in the sepsis without shock group and 56 cases in the control group. In the septic shock group, there were 17 cases at the compensated stage and 15 cases at the decompensated stage. There were 21 full-term infants (20 cured or improved and 1 died) and 11 premature infants (7 cured or improved and 4 died), with the mortality of 15.62% (5/32). There were 18 full-term infants and 7 premature infants in the sepsis without shock group and all cured or improved without death. The control group included 28 full-term infants and 28 premature infants transferring to NICU after birth. Non-invasive hemodynamic parameter analysis showed that SV, SVI, CO and CI of full-term infants in the septic shock group were significantly lower than those in the sepsis without shock group and control group [SV (mL): 3.52±0.99 vs. 5.79±1.32, 5.22±1.02, SVI (mL/m²): 16.80 (15.05, 19.65) vs. 27.00 (22.00, 32.00), 27.00 (23.00, 29.75), CO (L/min): 0.52±0.17 vs. 0.80±0.14, 0.72±0.12, CI (mL×s^-1×m^-2): 40.00 (36.67, 49.18) vs. 62.51 (56.34, 70.85), 60.01 (53.34, 69.68), all P < 0.05], while SVR and SVRI were significantly higher than those in the sepsis without shock group and control group [SVR (kPa×s×L^-1): 773.46±291.96 vs. 524.17±84.76, 549.38±72.36, SVRI (kPa×s×L^-1×m^-2): 149.27±51.76 vs. 108.12±12.66, 107.81±11.87, all P < 0.05]. MAP, SV, SVI, CO and CI of preterm infants in the septic shock group were significantly lower than those in the control group [MAP (mmHg, 1 mmHg ≈ 0.133 kPa): 38.55±10.48 vs. 47.46±2.85, SV (mL): 2.45 (1.36, 3.58) vs. 3.96 (3.56, 4.49), SVI (mL/m²): 17.60 (14.20, 25.00) vs. 25.50 (24.00, 29.00), CO (L/min): 0.32 (0.24, 0.63) vs. 0.56 (0.49, 0.63), CI (mL×s^-1×m^-2): 40.01 (33.34, 53.34) vs. 61.68 (56.68, 63.35), all P < 0.05], while SVR and SVRI were similar to the control group [SVR (kPa×s×L^-1): 1 082.88±689.39 vs. 656.63±118.83, SVRI (kPa×s×L^-1×m^-2): 126.00±61.50 vs. 102.37±11.68, both P > 0.05]. Further analysis showed that SV, SVI and CI of neonates at the compensation stage in the septic shock group were significantly lower than those in the control group [SV (mL): 3.60±1.29 vs. 4.73±1.15, SVI (mL/m²): 19.20±8.33 vs. 26.34±3.91, CI (mL×s^-1×m^-2): 46.51±20.34 vs. 61.01±7.67, all P < 0.05], while MAP, SVR and SVRI were significantly higher than those in the control group [MAP (mmHg): 52.06±8.61 vs. 48.54±3.21, SVR (kPa×s×L^-1): 874.95±318.70 vs. 603.01±111.49, SVRI (kPa×s×L^-1×m^-2): 165.07±54.90 vs. 105.09±11.99, all P < 0.05]; MAP, SV, SVI, CO and CI of neonates at the decompensated stage in the septic shock group were significantly lower than those in the control group [MAP (mmHg): 35.13±6.08 vs. 48.54±3.21, SV (mL): 2.89±1.17 vs. 4.73±1.15, SVI (mL/m²): 18.50±4.99 vs. 26.34±3.91, CO (L/min): 0.41±0.19 vs. 0.65±0.15, CI (mL×s^-1×m^-2): 43.34±14.17 vs. 61.01±7.67, all P < 0.05], while SVR and SVRI were similar to the control group [SVR (kPa×s×L^-1): 885.49±628.04 vs. 603.01±111.49, SVRI (kPa×s×L^-1×m^-2): 114.29±43.54 vs. 105.09±11.99, both P > 0.05]. CONCLUSIONS Full-term infant with septic shock exhibit a low cardiac output, high vascular resistance hemodynamic pattern, while preterm infant with septic shock show low cardiac output and normal vascular resistance. At the compensated stage the hemodynamic change is low output and high resistance type, while at the decompensated stage it is low output and normal resistance type. Non-invasive hemodynamic monitoring can assist in the identification of neonatal septic shock and provide basis for clinical diagnosis and treatment.
