OBJECTIVE To investigate the clinical efficacy and safety of Zhengxintai granules as in the treatment of microvascular angina （MVA） following percutaneous coronary intervention （PCI） in patients with acute ST-segment elevation myocardial infarction （STEMI） and qi deficiency and blood stasis syndrome. METHODS Patients with STEMI and qi deficiency and blood stasis syndrome who underwent PCI and developed MVA and were admitted to the Jinan Fourth People’s Hospital （Jinan Cardiovascular Hospital） from March 2022 to March 2025 were selected， they were randomly divided into the control group and the observation group according to a random number table， with 76 cases in each group. Patients in the control group received conventional Western medicine treatment combined with a placebo， while patients in the observation group received Zhengxintai granules （5 mg per dose， three times daily， for 8 weeks） in addition to conventional Western medicine treatment. The clinical efficacy [including the total effective rate of traditional Chinese medicine （TCM） syndrome improvement and the total effective rates of Western clinical efficacy] was compared between the two groups. The following indicators were detected before and after treatment： TCM syndrome scores， angina pectoris episodes [daily attack frequency， duration per attack， Visual Analogue Scale （VAS） score]， cardiac function indicators [lactate dehydrogenase （LDH）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， left ventricular end-diastolic dimension （LVEDD）， left ventricular end-systolic dimension （LVESD）， left ventricular ejection fraction （LVEF）， cardiac output （CO）， fractional shortening （FS）]， coagulation function indicators [thrombin time （TT）， prothrombin time （PT）， fibrinogen （FIB）]， fibrinolytic marker （D-dimer）， vascular endothelial function indicators [vascular endothelial growth factor （VEGF）， nitric oxide （NO）， endothelin-1 （ET-1）] and myocardial microcirculation hemodynamic indicators [end-diastolic velocity （EDV）， peak systolic velocity （PSV）， resistance index （RI）， pulsatility index （PI）]. The quality of life [Seattle Angina Questionnaire （SAQ） score] and the incidence of adverse reactions were also compared between the two groups. RESULTS There was no patient dropout during the entire course of the study. The total effective rates of improvement in TCM syndromes and the total effective rates of Western clinical efficacy in the observation group were significantly higher than those in the control group （93.42% vs. 82.89%， 94.74% vs. 84.21%， P＜0.05）. Before the treatment， the comparison of each examination indicator between the two groups showed no statistically significant differences （P＞0.05）. Compared with before treatment， the TCM syndrome scores， the number of daily angina pectoris attacks and the duration of each attack， the VAS scores， LDH， NT-proBNP， FIB， D-dimer， ET-1 levels， LVEDD， LVESD， RI and PI after treatment in both groups were significantly reduced， shortened or decreased （P＜0.05）； VEGF and NO levels， LVEF， CO， FS， TT， PT， EDV， PSV， and the standard scores of five dimensions including angina pectoris stability， as well as the total scores of SAQ， all significantly increased or prolonged （P＜0.05）. Furthermore， the improvements in the aforementioned indicators （except for LVEF） in the observation group were significantly greater than those in the control group （P＜0.05）. There was no statistically significant difference in the total incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS Zhengxintai granules， when used as an adjunct to conventional Western medicine， can significantly alleviate the related symptoms of MVA in STEMI patients with qi deficiency and blood stasis syndrome after PCI， repair damaged cardiac function， restore the balance of the coagulation-fibrinolysis system， improve vascular endothelial function and myocardial microcirculation perfusion， and significantly enhance the quality of life of patients

Objective To investigate the relationship of anxiety and depression mood with cognitive function in elderly patients with Parkinson's disease. Methods A total of 511 elderly Parkinson's disease patients who visited the 907th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from October 2024 to November 2025 were selected as the study subjects. The patients were divided into a cognitive impairment group (n=98) and a non-cognitive impairment group (n=413) based on the presence of cognitive impairment. The patient related data were collected. Disease severity was assessed using the modified Hoehn-Yahr (H-Y) staging scale, anxiety levels were evaluated with the Beck Anxiety Inventory (BAI), depressive symptoms were measured using the Geriatric Depression Scale (GDS), and cognitive function was assessed with the Mini-Mental State Examination. Logistic regression analysis was performed to identify risk factors for cognitive impairment in elderly Parkinson's patients, and Pearson correlation analysis was conducted to examine the relationship between anxiety/depression and cognitive function. Results Educational level (OR=5.348, 95% CI: 2.278-10.482), marital status (OR=6.056, 95% CI: 2.932-12.508), H-Y stage (OR=2.189, 95% CI: 1.433-3.345), BAI score (OR=1.270, 95% CI: 1.188-1.358), and GDS score (OR=1.340, 95% CI: 1.236-1.453) were all risk factors for cognitive impairment in elderly Parkinson's patients (P<0.05). Pearson correlation analysis showed that both BAI score and GDS score were negatively correlated with cognitive function (r=-0.383 and -0.400, respectively, P<0.001). Conclusion Educational level, marital status, H-Y stage, BAI score, and GDS score are all influencing factors for cognitive impairment in elderly Parkinson's disease patients, with both BAI scores and GDS scores being negatively correlated with cognitive function.

ObjectivesTo investigate the molecular epidemiological characteristics of HIV-1 infection among men who had sex with men (MSM) in Taizhou City, Zhejiang Province, and to provide a scientific reference for acquired immune deficiency syndrome prevention and control efforts. MethodsThe research subjects were all newly reported MSM population in Taizhou City from 2020 to 2023. Blood samples without antiviral therapy were collected. The HIV-1 pol gene was amplified and sequenced, and the sequences were submitted to the Stanford University drug resistance database to identify the mutation sites and drug resistance. MEGA 11.0 software was used to analyze the nucleic acid sequences, construct phylogenetic tree, and calculate genetic distance of gene sequences. The molecular transmission network diagram of HIV-1 was constructed using Cytoscape_v3.10.1, and the influencing factors of network entry were analyzed by logistic regression. ResultsA total of 363 newly reported HIV-infected MSM patients were included, with a median age [M (P₂₅, P₇₅)] of 34 (26,47) years old. The majority had an educational level of junior high school or below (55.65%). A total of eight subtypes were found, mainly CRF07_BC and CRF01_AE. The primary drug resistance rate was 10.47% (38/363). The optimal molecular network gene distance was 0.019, with a network access rate of 42.70% (155/363), and a total of 47 molecular clusters were formed. Multivariate logistic analyses showed that compared with the CRF01_AE subtype, the clustering risk of CRF07_BC subtype was higher (OR=1.916, 95%CI: 1.191‒3.109), cases with drug resistance had a higher risk of cluster formation than those without drug resistance (OR=2.011, 95%CI: 1.006‒4.080), and recent infected patients had a lower risk of entering the largest molecular cluster than long-term infected patients (OR=0.376, 95%CI: 0.137‒0.928). ConclusionThe newly diagnosed infections among the MSM population are active in Taizhou City, Zhejiang Province, with a high level of primary drug resistance. Individuals carrying drug-resistant strains are more likely to cluster. Drug resistance monitoring should be strengthened to prevent further spread of drug-resistant strains in the network.

ObjectiveTo investigate the diagnostic accuracy and grading capability of ultrasound-derived fat fraction （UDFF）， controlled attenuation parameter （CAP）， and hepatic/renal ratio （HRR） in assessing hepatic steatosis in metabolic associated fatty liver disease （MAFLD） with magnetic resonance imaging-proton density fat fraction （MRI-PDFF） as the gold standard. MethodsA total of 150 patients with MAFLD who attended The First Hospital of Hebei Medical University from January 2023 to December 2024 were enrolled， and 148 healthy volunteers were recruited. All subjects underwent MRI-PDFF， UDFF， CAP， and HRR examinations. Hepatic steatosis was graded based on MRI-PDFF （S0：148 cases； S1：92 cases； S2：21 cases； S3：37 cases）， and the MAFLD patients with different grades of hepatic steatosis were compared in terms of UDFF， CAP， HRR， and clinical features. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups and the Tukey HSD test was used for further comparision between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Mann-Whitney U test was used for further comparison between two groups； the chi-square test was used for comparison of categorical data between groups. The Spearman correlation analysis was used to investigate the correlation between UDFF， CAP， HRR， and MRI-PDFF in different grades of MAFLD； the receiver operating characteristic （ROC） curve was used to investigate the efficacy of UDFF， CAP， and HRR in the diagnosis of different degrees of hepatic steatosis in MAFLD； the Bland-Altman difference plot was used to analyze the consistency between UDFF and MRI-PDFF in different degrees of hepatic steatosis in MAFLD. ResultsUDFF measurement gradually increased with the increase in the grade of fatty liver （H=201.52，P0.001）. The Spearman correlation analysis showed that there was a strong correlation between any two indicators of UDFF， CAP， HRR， and MRI-PDFF in S1， S2， and S3 MAFLD （all P0.001）， with the strongest correlation between UDFF and MRI-PDFF （r_s1=0.884，r_s2=0.962，r_s3=0.929， all P0.001）. The ROC curve analysis showed that UDFF had a larger area under the ROC curve （AUC） than CAP and HRR in the graded diagnosis of S1 and S3 （all P0.05）， while in the diagnosis of S2 MAFLD， UDFF had a significantly larger AUC than HRR （P0.05） and a similar AUC to CAP （P0.05）. The Bland-Altman difference plot showed good consistency between UDFF and MRI-PDFF in different degrees of hepatic steatosis in MAFLD. ConclusionCompared with CAP and HRR， UDFF can accurately measure liver fat content and has good efficacy in identifying varying degrees of hepatic steatosis in MAFLD.

Objective To quantitatively evaluate age-,sex-,and segment-related characteristics of lumbar disc degeneration(LDD)in patients with low back pain(LBP)using T1rho MRI,and assess its diagnostic value in early-stage disc degeneration.Methods A retrospective cross-sectional study was conducted on 89 LBP patients(balanced distribution across ages 20～29,30～39,40～49,50～59 years and genders)admitted in Department of Orthopedics of First Affiliated Hospital of Army Medical University from March 2024 to February 2025.All patients underwent lumbar MRI including T1rho sequences.Two senior radiologists performed blinded Pfirrmann grading on 445 intervertebral discs and measured T1rho values of the nucleus pulposus(NP).Kappa test was used to evaluate the inter-observer agreement of Pfirrmann grading,and Spearman correlation coefficient was employed to analyze the correlation between Pfirrmann grade and NP-T1rho value.Disc degeneration characteristics were compared across different ages,sexes,and spinal segments.After adjusting for body mass index(BMI)and gender,partial correlation analysis was used to assess the correlation between NP-T1rho value of each lumbar segment and age.Receiver operating characteristic(ROC)curve was plotted to analyze the diagnostic performance of T1rho quantification for early LDD in LBP patients.Results Good inter-observer agreement was observed in Pfirrmann grading across segments,with a Kappa coefficient of>0.70.The NP-T1rho values of all NP were in a strong negative correlation with Pfirrmann grades(r=-0.877,P<0.001).The NP-T1rho values were progressively decreased from Pfirrmann gradesⅠ to Ⅳ(P<0.001),with a steep decline between gradesⅡ and Ⅲ.The patients aged 20～29 and 30～39 years showed significantly higher NP-T1rho values in Pfirrmann grades Ⅰ and Ⅱ discs when compared with those aged 40～49 and 50～59 years(P<0.05).The males had significantly higher mean NP-T1rho values in grade I than the females(P=0.006).In the upper spinal segments(L1～L4),the males exhibited significantly higher mean NP-T1rho value than the females(P=0.025),and NP-T1rho value was decreased obviously with increase of age across all age groups(P<0.05).Except L5/S1 segments,NP-T1rho value and age in all spinal segments had significant negative correlations(r=-0.548～-0.349,P<0.001).The area under the curve(AUC)for distinguishing grade Ⅰ from Ⅱ discs was 0.824(95%CI:0.772～0.876),and for grades Ⅱ from Ⅲ was 0.978(95%CI:0.964～0.992).Conclusion T1rho MRI provides accurate quantitative assessment of early lumbar disc degeneration in LBP patients,with an NP-T1rho value of 79.87 ms serving as a discriminative threshold between grade Ⅱ and grade Ⅲ.

The biotransformation processes in the human body play a crucial role in maintaining the inter-nal environment's stability by converting exogenous compounds and endogenous metabolites into substances with increased polarity or water solubility.This alteration in toxicity or pharmacological effects facilitates their excretion from the body.Sulfation,an important type of phase Ⅱ biotransformation reaction,is primarily me-diated by members of the cytosolic sulfotransferases(also known as sulfotransferases,SULTs)superfamily.Recent studies have uncovered the significant roles of SULTs in drug metabolism,tumorigenesis,inflammato-ry responses,hormone regulation,and energy metabolism.This article provides a comprehensive review of the regulatory roles and molecular mechanisms of the SULTs superfamily members in carbohydrate and lipid me-tabolism,aiming to offer new insights into the mechanism research and drug development for disorders related to carbohydrate and lipid metabolism dysregulation.

Objective To investigate the effect of miR-132-3p on epithelial-mesenchymal transition(EMT)of trophoblast cells through targeted regulation of the SIRT1/NF-κB pathway.Methods Placental tissues from 37 pre-eclampsia(PE)patients who underwent cesarean section in Zhengzhou Women&Infants Hospital and 37 normal pregnant women who underwent cesarean section were collected as the research group and control group,respectively.RT-qPCR was performed to detect the expression of miR-132-3p and SIRT1 in tissues.During the logarithmic pro-liferation phase,HTR-8/SVneo cells were grouped into inhibitor negative group,miR-132-3p inhibitor group,mimic negative group,miR-132-3p overexpression group,miR-132-3p inhibitor+interference negative group,and miR-132-3p inhibitor+interference SIRT1 group,with untransfected HTR-8/SVneo cells as the blank group.CCK-8,Transwell assay,scratch assay,and RT-qPCR were used to detect the proliferation,invasion,migration,and changes in miR-132-3p and SIRT1 mRNA expression of HTR-8/SVneo cells.Western blot was used to detect the expression levels of EMT related proteins and SIRT1,NF-κB proteins.Dual luciferase was used to validate the targeting relationship between miR-132-3p and SIRT1.Results The level of miR-132-3p in the research group was significantly higher than that in the control group,while the SIRT1 mRNA was lower(P＜0.05).The level of miR-132-3p,E-cadherin,p-NF-κBp65/NF-κBp65 in the miR-132-3p inhibitor group was lower than those in the inhib-itor negative group and blank group.The proliferation rate,invasion cell number,migration rate,level of vimentin,N-cadherin,and SIRT1 were all higher(P＜0.05).The miR-132-3p,E-cadherin,p-NF-κBp65/NF-κBp65 in the miR-132-3p overexpression group were higher than those in the mimic negative group,the proliferation rate,inva-sion number,migration rate,vimentin,N-cadherin,and SIRT1 were lower(P＜0.05).The level of E-cadherin and p-NF-κBp65/NF-κBp65 in the miR-132-3p inhibitor+interference SIRT1 group was higher than those in the miR-132-3p inhibitor+interference negative group(P＜0.05),the proliferation rate,invasion number,migration rate,vimentin,N-cadherin,and SIRT1 expression were lower(P＜0.05).MiR-132-3p targeted regulation of SIRT1 expression(P＜0.05).Conclusions Inhibition of miR-132-3p promotes the EMT,proliferation,invasion,and migration of trophoblast cells by targeting and activating the SIRT1/NF-κB pathway.

Objective:To evaluate the utility of pulse oximetry-derived parameters—specifically, the pulse oximetry plethysmographic waveform area under the curve (POP AUC) and the peripheral perfusion index (PPI)—in assessing disease severity and predicting prognosis in patients with sepsis. Methods:In this prospective descriptive study, 68 patients with sepsis were categorized based on illness severity into septic shock and non-shock groups, and by 28-day outcome into survival and non-survival groups. POP AUC, PPI, and lactate (Lac) levels were recorded at 0, 24, 48, 72, and 96 hours after admission. APACHEⅡ and SOFA scores were calculated within the first 24 hours. The prognostic value of these parameters was evaluated. Results:Significant differences were observed between the septic shock and non-shock groups in POP AUC, PPI, Lac (all P < 0.05 except at 96 h), APACHEⅡ, and SOFA scores (all P < 0.05). These differences were most pronounced at admission: POP AUC0 (2475.1 ± 899.0) vs. (4260.3 ± 1028.5), PPI 0 (0.78 ± 0.74) vs. (3.13 ± 2.18), Lac 0 (4.95 ± 4.32) vs. (2.07 ± 1.55), APACHE Ⅱ (16.78 ± 5.59) vs. 11.82 ± 4.89), and SOFA (8.89 ± 3.25) vs. (5.06 ± 2.60). Optimal prognostic cut-off values were 2741.43 for POP AUC, 0.97 for PPI, 2.05 for Lac, 12.5 for APACHEⅡ, and 5.5 for SOFA. ROC curve analysis showed that at 24 hours, POP AUC and PPI had significantly larger AUC values than Lac ( P < 0.05), while no significant differences were found among other parameters. Significant differences between non-survivors and survivors were also found in POP AUC, PPI (at 0, 24, and 48 h), APACHE II, and SOFA (all P < 0.05). No significant differences were observed in PPI (72 h and 96 h) or Lac between the two outcome groups. Conclusions:POP AUC and PPI, as derived from pulse oximetry, are non-inferior to Lac, SOFA, and APACHEⅡ scores in evaluating disease severity and predicting 28-day mortality in sepsis patients. These parameters show promise as practical and non-invasive tools for clinical assessment in sepsis.
