Objective To investigate the clinical diagnostic value of serum sTREM2 level in patients with cerebral small vessel disease(CSVD)and its correlation with depression and its severity.Methods A total of 208 CSVD inpatients admitted in Department of Neurology of the First Affiliated Hospital of Shihezi University from December 2023 to November 2024 were en-rolled,and according to their score of HAMD,they were divided into a depression group(CSVD+D group,112 cases)and a non-depression group(CSVD—D group,96 cases).According to the 17-item HAMD,the depression group(CSVD+D group)was further divided into mild(8-17,n=80),moderate(18-24,n=27)and severe depression(≥25,n=5)subgroups.Another 208 healthy individuals who taking health checkups in the same period were selected and served as the control group.The general clinical data were compared among the groups and subgroups,and mul-tivariate logistic regression analysis was applied to identify the risk factors for the occurrence of depression and the relationship between sTREM2 and depression severity in the CSVD patients.ROC curve was plotted to evaluate the predicative performance of serum sTREM2 level for the occurrence of depression in the CSVD patients.Results The serum sTREM2 level was remark-ably higher in the CSVD patients than the control group(5.95±3.82 μg/L vs 1.40±1.21 μg/L,P＜0.01).ROC curve analysis indicated that the AUC value of serum sTREM2 level in predicting CSVD was 0.917,with a sensitivity of 87.52％and a specificity of 85.64％,and an optimal cut-ff value of 2.272 μg/L.The CSVD+D group also had significantly higher serum sTREM2 level than the CSVD—D group(6.40±3.93 μg/L vs 5.01±2.87 μg/L,P＜0.01).Multivariate logistic regression analysis showed that serum sTREM2 level was an independent influencing factor for occurrence of depression in the CSVD patients(OR=1.115,95％CI:1.019-1.220,P=0.018).Statistical difference was also observed in the patients without and with mild,moderate and severe depression(P＜0.05).Multivariate ordinal logistic regression analysis revealed that serum sTREM2 level was an independent influencing factor for mild,moderate and severe depression(OR=1.113,95％CI:1.013-1.223,P=0.026;OR=1.135,95％CI:1.004-1.284,P=0.043).The AUC value of serum sTREM2 level in predicting depressive symptoms in CSVD patients was 0.603.Conclusion Serum sTREM2 is closely associated with CSVD patients.Its level may provide certain reference value for clinical diagnosis of CSVD,and has potentially predictive value for the occurrence of depression in the CSVD patients.

Objective To explore the correlation between remnant cholesterol level and CI-AKI in elderly patients with ACS and concomitant T2DM following PCI.Methods A retrospective case-control study was conducted on 759 elderly T2DM patients with ACS undergoing PCI in the Affi-liated Hospital of Xuzhou Medical University between January 2020 and December 2023.The pa-tients were randomly allocated into a training group(n=608)and a validation group(n=151)in a ratio of 8∶2.Based on CI-AKI diagnostic criteria,the training group was further stratified into a CI-AKI subgroup(n=95)and a non-CI-AKI subgroup(n=513).Multivariate logistic regression analysis was used to identify the independent risk factors for CI-AKI.Results The remnant cho-lesterol level was significantly higher in the CI-AKI subgroup than the non-CI-AKI subgroup[0.78(0.51,1.07)mmol/L vs 0.57(0.40,0.81)mmol/L,P＜0.01].Red blood cell count,remnant cholesterol,age,uric acid,log-transformed systemic immune-inflammatory(SII)index,and cysta-tin C were identified as independent predictors for CI-AKI in T2DM patients with ACS after PCI(P＜0.01).ROC curve analysis demonstrated that the model combining remnant cholesterol with other independent predictors exhibited superior discriminative performance in both the training group(AUC=0.818,95％CI:0.773-0.863)and validation group(AUC=0.787,95％CI:0.686-0.889)when compared to the models excluding remnant cholesterol(P＜0.01).Conclusion Rem-nant cholesterol is an independent predictor of CI-AKI in elderly patients with ACS and T2DM af-ter PCI.A risk prediction model based on remnant cholesterol and other independent risk factors demonstrates enhanced predictive performance for postoperative CI-AKI in the patients.

Objective To explore the relationship between overactive bladder(OAB)and neuropsychological characteristics in patients with cerebral small-vessel disease(CSVD).Methods A total of 208 patients with CSVD admitted to the First Affiliated Hospital of Shihezi University from December 2023 to November 2024 were selected as research subjects.They were divided into OAB group(44 cases)and non-OAB group(164 cases)according to overactive bladder symptom score.The general information and imaging data of two groups of patients were compared.The cognitive function,anxiety and depression of patients were evaluated by using Montreal cognitive assessment(MoCA),digit span test(DST),auditory verbal learning test(AVLT),verbal fluency test(VFT),clock drawing test(CDT),Hamilton anxiety scale(HAMA)and Hamilton depression scale(HAMD).Logistic regression analysis was used to analyze the influencing factors of OAB in patients with CSVD.Pearson correlation analysis was used to analyze the correlation between imaging indicators and anxiety symptoms of patients in OAB group.Results The HAMA and HAMD scores of patients in OAB group were higher than those in non-OAB group(P＜0.05),but there were no statistically significant differences in MoCA,DST,AVLT,VFT,and CDT scores between two groups(P＞0.05).There was a statistically significant difference in the incidence of anxiety among patients with different degrees of OAB(P＜0.05).Multivariate Logistic regression analysis after adjusting for confounding factors showed that anxiety was an independent influencing factor for OAB in patients with CSVD(P＜0.05).The periventricular white matter hyperintensity of patients in OAB group was negatively correlated with the HAMA score(P＜0.05),while basal ganglia lacunar infarction,centrum semiovale lacunar infarction,basal ganglia enlarged perivascular space and centrum semiovale enlarged perivascular space were all positively correlated with the HAMA score(P＜0.05).Conclusion The anxiety and depression symptoms of patients with CSVD accompanied by OAB were more severe than those of non-OAB patients.Anxiety may be an independent influencing factor for the occurrence of OAB in patients with CSVD.

Using conventional broth microdilution assays,the synthetic phenolic antioxidant 2,6-di-tert-butyl-4-methylphenol(butylated hydroxytoluene,BHT)was screened for synergistic antimi-crobial activity with β-lactam antibiotics.Further validation through checkerboard assays,growth curve analysis,and time-kill curve experiments confirmed the synergistic effect of BHT and β-lac-tams against methicillin-resistant Staphylococcus aureus(MRSA)(FICI≤0.5).To elucidate the underlying mechanism of synergy,this study evaluated changes in membrane permeability and pro-ton transmembrane gradients-key factors in biofilm functionality-along with critical indicators of bacterial energy metabolism,including ATP levels and the NAD+/NADH ratio.The results dem-onstrated that BHT disrupts the proton motive force(PMF),impairs membrane potential,and perturbs bacterial energy homeostasis,thereby significantly enhancing the antibacterial efficacy ofβ-lactams.Furthermore,a murine pneumonia infection model was established to assess the in vivo therapeutic efficacy of BHT combined with amoxicillin.The combination therapy alleviated pulmo-nary tissue damage,reduced bacterial loads in target organs(liver,spleen,and lungs),and decreased systemic inflammatory responses.This study elucidates the synergistic antimicrobial action and mechanistic basis of BHT combined with amoxicillin,offering a novel combinatorial therapeutic strategy to address MRSA resistance.The findings hold significant clinical potential and research value for overcoming antibiotic resistance in MRSA infections.

Objective To explore the relationship between serum high mobility group protein B1(HMGB1)level and anxiety symptoms in patients with cerebral small vessel disease(CSVD).Methods A total of 165 CSVD patients admitted in our department from December 2022 to July 2023 were enrolled as the research subjects.All of them were evaluated by neurologists with Hamilton Anxiety Rating Scale(HAMA),and then those with HAMA score ≥7 were assigned into an anxiety group(70 cases),and the other into a non-anxiety group(95 cases).Non paramet-ric rank sum test was used to compare the serum level of HMGB1 between the two groups of pa-tients.Logistic regression analysis was employed to analyze the risk factors affecting anxiety symptoms in CSVD patients.ROC curve was plotted to evaluate the predictive value of HMGB1 for anxiety symptoms in the patients.Results The serum HMGB1 level was significantly higher in the anxiety group than the non-anxiety group[287.01(188.19,355.54)ng/L vs 260.87(146.48,328.16)ng/L,P＜0.05].Multivariate logistic regression analysis showed that after adjusting for confounding factors,serum HMGB1 level was still a risk factor for anxiety symptoms in CSVD patients(OR=1.004,95％CI:1.000-1.007,P=0.046).Spearman correlation analysis indicated that HMGB1 level was positively correlated with total score of HAMA,insomnia score,and psy-chogenic score(P＜0.05,P＜0.01).The AUC value of HMGB1 in predicting anxiety symptoms in CSVD patients was 0.609(P=0.020).Conclusion Serum HMGB1 level is associated with the oc-currence of anxiety symptoms in CSVD patients,and it has predictive value for the anxiety symp-toms in CSVD patients.

【Objective】 To compare the clinical efficacy of high frequency holmium laser in the treatment of 2-3 cm renal calculi by minimally invasive percutaneous nephrolithotomy (mPCNL) and retrograde intrarenal surgery (RIRS). 【Methods】 The clinical data of 105 patients with a solitary 2-3 cm renal calculus treated during Oct. 2020 and Oct. 2022 were retrospectively analyzed. The patients were divided into two groups, including 52 cases in the RIRS group and 53 cases in the mPCNL group. The one-stage stone clearance rate, operation time, hemoglobin decline within 24 hours, inflammatory indicators within 24 hours after operation, postoperative complications, hospital stay and hospitalization costs were compared between the two groups. 【Results】 There were no significant differences in the preoperative general data, one-stage stone clearance rate, inflammatory indicators within 24 hours and incidence of postoperative complications between the two groups (P>0.05). The RIRS group had less decrease of hemoglobin than the mPCNL group [(6.35±2.00) g/L vs. (12.25±5.72) g/L, P=0.001], shorter hospital stay [(5.13±0.82) d vs. (7.92±1.59) d, P<0.001], lower hospitalization costs [(15 221.52±796.46) yuan vs. (19 514.51±909.98) yuan, P<0.001], but longer operation time [(58.17±7.67) min vs. (49.60±4.52) min, P<0.001]. 【Conclusion】 Both mPCNL and RIRS are safe and effective in the treatment of 2-3 cm renal calculi with 40-80 Hz holmium laser, and the one-stage stone clearance rate is similar. Although RIRS needed longer operation time than mPCNL, it has the advantages of less surgical trauma, faster postoperative recovery and shorter hospital stay, and is more prospective in the treatment of 2-3 cm renal calculi.
