Objective To evaluate the changes of perivascular space(PVS)in patients with subacute ischemic stroke(IS),as well as the relationship between PVS and cognitive dysfunction in IS patients,and to analyze the relationship between PVS indicators and cognitive function in subacute IS patients of different ages.Methods A total of 44 healthy controls(HC)and 39 patients with subacute IS were prospectively included.Automated quantitative analysis of MRI data was conducted to determine pPVS in the white matter and subcortical regions.Differences in pPVS between patients with subacute IS and HC were compared.Correlations between age,pPVS,and cognitive dysfunction were analyzed and modeled.Results Compared with the HC,the white matter pPVS in patients with subacute IS was significantly reduced(t=-2.21,P=0.031).In patients with subacute IS,the white matter pPVS showed a significant positive correlation with lesion volume(r=0.42,P=0.030)and mini-mental state examination(MMSE)scores(r=0.44,P=0.018).Both white matter pPVS(r=-0.42,P=0.010)and MMSE scores(r=-3.82,P=0.000 7)were negatively correlated with age.When age was over 61.35 years,there was a positive correlation between the white matter pPVS and MMSE scores.Conclusion PVS are closely related to cognitive impairment in patients with subacute IS.Age is a significant modulating factor in the relationship between PVS and cognitive dysfunction.Early monitoring of PVS and targeting it for intervention may positively impact the improvement of cognitive dysfunction following IS.

Objective:To explore the correlation between intrahepatic cholestasis of pregnancy(ICP)and ad-verse pregnancy outcomes.Methods:A total of 511 singleton pregnant women with ICP treated at The Third Affili-ated Hospital of Guangzhou Medical University from August 2017 to January 2024 were selected as the study sub-jects.Among them,patients were divided into the adverse pregnancy outcome group(n=49)and the control group without adverse pregnancy outcomes(n=462).The general and clinical data of the two groups were com-pared and analyzed.Results:①General situation:The number of pregnancies and deliveries,ICU transfer rate,total hospital stay,and total hospitalization costs were significantly higher in the adverse pregnancy outcome group compared to the control group(P<0.05).The number of prenatal check-ups,diagnostic gestational weeks,and gestational weeks at delivery were significantly lower compared to the control group(P<0.05).②Clinical symp-toms:The incidence of itching in the adverse pregnancy outcome group was lower compared to the control group(10.2%vs.26.6%,P<0.05),while other symptoms such as rash,fatigue,jaundice,and gastrointestinal symp-toms showed no significant difference between the two groups(P>0.05).③Laboratory examinations:Compared with the control group,patients in the adverse pregnancy outcome group had significantly the increased levels of alanine aminotransferase,aspartate aminotransferase,uric acid,urea nitrogen,and triglycerides,and significantly the decreased levels of alkaline phosphatase and fasting blood glucose,with statistical significance(P<0.05).Other biochemical indicators showed no significant difference between the two groups(P>0.05).④ICP grading and complications:The proportion of early-onset ICP,severe and very severe ICP in the adverse pregnancy out-come group was significantly higher compared to the control group(P<0.001);the proportion of adverse preg-nancy outcome group with pregnancy-induced hypertension was significantly higher compared to the control group;the incidence of preterm birth,fetal growth restriction,meconium-stained amniotic fluid,and fetal distress in the adverse pregnancy outcome group was significantly higher compared to the control group(P<0.001).⑤Neo-natal outcomes:The neonatal Apgar scores(1 min,5 min,10 min)and neonatal weight in the adverse pregnancy outcome group were lower compared to the control group(P<0.001),and the incidence of mild neonatal asphyx-ia was significantly higher,with a statistically significant difference(P<0.001).Conclusions:The severity of ICP is closely related to the occurrence of adverse pregnancy outcomes.Therefore,it is clinically necessary to pay at-tention to the grading of ICP,closely monitor the levels of total bile acids and liver enzymes,and try to avoid ad-verse pregnancy outcomes,especially intrauterine fetal death.

Objective:To investigate the relationship between CXCL6 expression and prostate cancer,as well as its effects on the malignant progression of PC-3 cells and the underlying mechanisms.Methods:Multiple databases were used to analyze CXCL6 expression in prostate cancer.And survival analysis,GO,and KEGG enrichment analysis were conducted.According to the concentration of CXCL6,PC-3 cells were divided into 0,100 and 200 ng/ml CXCL6 groups.The effects of up-regulated CXCL6 expression on PC-3 cell proliferation,migration,apoptosis,cycle,and related genes were investigated using CCK-8,EdU assay,scratch test,flow cytometry,and prostate cancer-targeted PCR array.Results:Database analysis revealed that CXCL6 was significantly down-regulated in prostate cancer(P＜0.05),and patients with low CXCL6 expression had a worse prognosis(P＜0.05).In prostate cancer,proteins associated with CXCL6 expression included CXCL1 and CXCL2,and related genes included MIR325 and RASSF6.GO analysis indicated that differentially expressed genes(DEGs)of CXCL6 were primarily enriched in processes such as response to chemokines and the tubular endoplasmic reticulum network(P＜0.05).KEGG analysis showed that DEGs were mainly enriched in signaling pathways such as the Hippo signaling pathway(P＜0.05).CCK-8,EdU assay,scratch test,and flow cytometry results demonstrated that compared with the 0 ng/ml CXCL6 group,the 100 and 200 ng/ml CXCL6 groups exhibited significantly reduced proliferation and migration rates(P＜0.05),significantly increased apoptosis rate(P＜0.05).And the proportion of S-phase cells in the 200 ng/ml CXCL6 group was lower compared to the 0 ng/ml CXCL6 group(P＜0.05).PCR array results showed that compared with the 0 ng/ml CXCL6 group,the expression of genes such as CDH1 and HAL was increased in the 200 ng/ml CXCL6 group,while the expression of genes such as CD5L and EDNRB was decreased.Conclusion:CXCL6 plays a significant role in the malignant progression of PC-3 cells,and its mechanism may be associated with the methylation of promoters of genes such as RASSF1,RARB,and CDH1.

Objective:To evaluate the efficacy of bevacizumab in reducing dyspnea, avoiding tracheostomy, and assessing the overall safety and effectiveness of the treatment in patients with juvenile-onset recurrent respiratory papillomatosis (JORRP).Methods:This study included 19 patients with JORRP treated with Bevacizumab at the Department of Otolaryngology-Head and Neck Surgery, BenQ Medical Center, from March 2022 to June 2024. The age of patients ranged from 1.0 to 27.0 years (10.47±8.45 years), with age at onset ranging from 0.5 to 15.0 years (3.66±3.70 years). The cohort included 11 males and 8 females. Bevacizumab was administered intravenously at a dose of 10 mg/kg every three weeks for three sessions. Efficacy was evaluated by comparing the standardized lesion volume pre-and post-treatment, with statistical analysis performed using R software (4.3.1).Results:Among the 19 patients, 11 presented with dyspnea before treatment. All patients experienced varying degrees of dyspnea relief within 72 hours following the initial treatment, and only one patient had mild dyspnea by the second treatment session three weeks later. The average reduction rates at 24 and 48 hours post-initia treatment were 25.75% and 47.16%, respectively. Following three treatment cycles, the average cumulative reduction rate was 67.47%, significantly higher than after the first treatment ( Z=3.38, P=0.002). Throughout the treatment period, no adverse events that of grade 2 or higher were noted. Conclusions:Bevacizumab can rapidly alleviate dyspnea symptoms and significantly reduce lesion volume in JORRP patients, exhibiting satisfactory overall safety and effectiveness. However additional large-scale prospective studies are warranted to validate its long-term safety and efficacy.

Objective:To investigate the relationship between the weight-adjusted waist index(WWI)and acute,subacute pain or chronic pain among American adults.Methods:There was a cross-sectional study.Data from the 1999-2004 National Health and Nutrition Examination Survey(NHANES)con-cerning waist circumference,weight,pain status and covariates(age,gender,race,marital status,edu-cation level and income,physical activity,alcohol consumption,smoking status,and diabetes)were extracted for analysis.Multinomial Logistic regression was conducted across the three models to investi-gate the associations between WWI and acute,subacute and chronic pain.Model 1 did not involve any adjustments.Model 2 involved adjustments for age,gender,race,marital status,education level,and income.Model 3 was further adjusted for physical activity,alcohol consumption,smoking,and diabetes status.Results:This study involved 12 694 participants with an average age of(50.6±18.7)years.Among all the participants,9 614 people(75.74％)had no pain,870 people(6.85％)experienced acute pain,354 people(2.79％)suffered from subacute pain,and 1 856 people(14.62％)experienced chronic pain.The WWI of all the participants was(10.95±0.85)cm/√kg,divided into four groups based on quartiles:Group Q1(7.90-10.36)cm/√kg,group Q2(10.37-10.94)cm/√kg,group Q3(10.95-11.53)cm/√kg and group Q4(11.54-15.20)cm/√kg.With the increase of WWI,the analysis revealed a significant statistical difference in the participants'acute and chronic pain status(all P＜0.001).In Model 1,the prevalence of acute pain was lower in group Q2 and group Q4 compared with group Q1(group Q2:OR=0.765,95％CI:0.615-0.953,P=0.017;group Q4:OR=0.648,95％CI:0.503-0.835,P＜0.001).Compared with group Q1,the prevalence of chronic pain increased in group Q2,group Q3,and group Q4(group Q2:OR=1.365,95％CI:1.149-1.622,P＜0.001;group Q3:OR=1.291,95％CI:1.082-1.541,P=0.005;group Q4:OR=1.874,95％CI:1.579-2.224,P＜0.001).In Model 2,compared with group Q1,an increase in chronic pain preva-lence was still associated with an increase in WWI in other three groups(group Q2:OR=1.359,95％CI:1.137-1.624,P=0.001;group Q3:OR=1.260,95％CI:1.039-1.528,P=0.019;group Q4:OR=1.735,95％CI:1.413-2.132,P＜0.001).In Model 3,group Q4 had a 49.2％increased prevalence of chronic pain compared to group Q1(OR=1.492,95％CI:1.208-1.842,P＜0.001).However,in Models 2 and 3,no significant relationship was observed between acute pain and WWI(all P＞0.05).And none of the three models identified a significant association between subacute pain and WWI(all P＞0.05).Conclusion:For American adults,there was no significant correlation between WWI and acute pain or subacute pain.However,as WWI increases,so does the prevalence of chronic pain.Further validation of this conclusion through large-scale prospective studies is warranted.

Objective:To investigate the adjunctive diagnostic value of retinal imaging structural parameters combined with apolipoprotein E (ApoE) gene polymorphisms for Alzheimer′s disease (AD).Methods:It was a case-control study, 71 confirmed AD patients who attended the Department of Neurology in Sichuan Provincial People′s Hospital from May 2023 to June 2024 and 156 healthy medical checkups who participated in medical checkups in the Health Management Center were continuously with convenience sampling method; the subjects were included as the AD case group and healthy control group, respectively. Optical coherence tomography (OCT) was used to measure the structural parameters of retinal imaging such as the thickness of the retinal nerve fiber layer (RNFL) and the retinal nerve fiber layer-inner plexiform layer (RNFL-IPL) in the study subjects. Information on demographic characteristics and disease history of the study participants were collected through a questionnaire, and venous blood was collected to test for ApoE gene polymorphisms. The retinal imaging structural parameters, ApoE gene polymorphisms and other related indicators were included in a multifactorial logistic regression model to analyze the main factors affecting the risk of AD. Based on the results of the multifactorial analysis, the receiver operating characteristic (ROC) curves were plotted and the areas under the curve (AUC) were calculated to evaluate the efficacy of different models in the adjunctive diagnosis of AD.Results:Of the 227 study subjects included in the analysis, 153 were females and 74 were males; there were 71 cases in the AD case group with a mean age of (66.73±8.83) years, and there were 156 subjects in the healthy control group with an average age of (61.95±8.21) years. Educational attainment of elementary school and below ( OR=4.683, 95% CI: 2.133-10.282), living visual acuity<0.5 ( OR=2.716, 95% CI: 1.12-6.583), and carrying ≥1 ApoE ε4 genes ( OR=5.331, 95% CI: 2.309-11.891) were positively correlated with the risk of AD. RNFL thickening ( OR=0.923, 95% CI: 0.854-0.998) was negatively associated with the risk of AD (all P<0.05). The AD risk assessment model (Model 4), which included fundus imaging features and ApoE gene polymorphisms, had the highest predictive efficacy (AUC=0.857, P<0.001). Conclusion:Retinal imaging structural parameters differ significantly between AD patients and healthy examinees, and a risk assessment model combining retinal imaging structural parameters and ApoE gene polymorphisms has high predictive value and is expected to serve as an auxiliary diagnostic tool for AD.

Objective:To investigate the relationship between different states of cardiac function and their changes during the course of diabetic foot ulcers(DFU), and to evaluate their impact on patient prognosis.Methods:A retrospective analysis was conducted on 194 DFU patients who were rehospitalized at approximately 3-month intervals. Basic clinical data and cardiac function-related indicators were collected at baseline and follow-up. Patients were followed until death or until November 10, 2024. Outcomes including ulcer healing, recurrence, minor amputation, and death were recorded. Logistic regression models were used to analyze the effects of cardiac function status and its changes on these four outcomes. Results:After treatment, the proportion of patients with NYHA class Ⅱ-Ⅲ decreased significantly from 33.5% at baseline to 21.6%( P=0.009). Serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) level also decreased after treatment compared with baseline [635.85(59.83, 453.28) pg/mL vs 728.67(81.48, 696.15) pg/mL, P=0.055]. Serum NT-proBNP level was significantly higher in the death group compared to the survival group( P=0.002). The proportion of DFU patients with baseline NYHA class Ⅱ-Ⅲ was significantly higher than that in those with class Ⅰ( P=0.012). Regression analysis showed that an improvement in NT-proBNP levels was associated with a lower risk of DFU recurrence( OR=0.378, 95% CI 0.183-0.779, P=0.008), and improvement in NYHA class was associated with a lower mortality risk( OR=0.074, 95% CI 0.020-0.275, P<0.001). Conclusion:Cardiac function status and its changes during the treatment of DFU patients have strong prognostic implications, particularly in predicting the risk of recurrence and death outcomes.

Objective:To analyze the clinical characteristics and outcomes of Haemophilus influenzae (Hi) meningitis in children. Methods:This is a retrospective case series study. This study included 34 Hi meningitis patients who admitted to Beijing Children′s Hospital, Capital Medical University, from January 1, 2010, to December 31, 2023. Data on clinical presentations, laboratory tests, hearing assessment and outcomes at discharge were collected. Patients were divided into 2 groups according to the outcome at discharge: favorable outcome group and unfavorable outcome group. Mann-Whitney U test and Fisher exact test was used to estimate the risk factors for an unfavorable outcome at discharge. Results:Thirty-four patients were enrolled. There were 16 males and 18 females. The age at onset ranged from 3 months to 12 years. Fever (34 patients (100%)), convulsions (17 patients (50%)), and coma (21 patients (62%)) were the common clinical presentations. Twenty-four patients (71%) developed complications. There were 15 patients (44%) needed treatment in the intensive care unit, 5 patients (15%) received intubation, and 4 patients (12%) had developed shock. The favorable outcome group included 23 patients, and the unfavorable outcome group included 11 patients. Female, patients with limb movement disability, dystonia, ventriculomegaly or hydrocephalus, and a concentration of glucose in the initial cerebrospinal fluid lower than 1 mmol/L were risk factors of unfavorable outcome at discharge (all P<0.05). Among the 23 patients (68%) in favorable outcomes group, 13 patients (57%) had data available on their long-term follow-up results, including 12 patients with favorable long-term outcomes and 1 patient with unfavorable long-term outcome. Among the 11 patients (32%) in unfavorable outcomegroup, 1 patient died, the other 10 patients (91%) had data available on their long-term outcomes. Eight patients had unfavorable long-term outcomes and 2 patients with favorable long-term outcomes. Patients who had unfavorable outcomes at discharge were at a greater risk of experiencing unfavorable long-term outcomes ( P=0.001). Conclusions:It is common for patients with Hi meningitis to have intracranial complications or develop into critical conditions. Patients who have limb movement disability, dystonia, ventriculomegaly or hydrocephalus, and who exhibit a concentration of glucose in the initial cerebrospinal fluid lower than 1 mmol/L tend to have unfavorable outcomes; they need to be assessed for sequelae.

Objective:To investigate the dynamic changes of cytokine levels in patients with sepsis and to identify potential biomarkers for evaluating the prognosis of the disease.Methods:A total of 195 patients with sepsis hospitalized at the Department of Infectious Diseases and the Department of Critical Care Medicine of the First Affiliated Hospital of Soochow University from August 2022 to October 2024 were recruited, and 70 healthy individuals undergoing physical examinations were recruited as the healthy control group. The levels of 11 cytokines, including interferon γ (IFN-γ), interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12P70, IL-17A, tumor necrosis factor α (TNF-α) and C-reactive protein (CRP) were compared between the sepsis patients and the healthy controls. Spearman correlation analysis was used to assess the correlation between cytokine levels and sequential organ failure assessment (SOFA) scores in sepsis patients. Receiver operating characteristic curves were plotted and the area under the curve (AUC) was calculated to evaluate the diagnostic value of cytokines for sepsis. Delong test was used to compare AUC. Based on the 28-day survival outcomes, the sepsis patients were categorized into non-survival group and survival group. The levels of the 11 cytokines in patients on the 1st, 3rd, 7th, 14th, 21st and 28th days after confirmed sepsis were dynamically monitored, and their change characteristics were analyzed. Mann-Whitney U test was used for statistical comparison. Results:The age of the 195 patients with sepsis was 68.0 (55.0, 76.0) years old, including 124 males (63.6%), 64 died and 131 survived.The levels of IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12P70, IL-17A, TNF-α, CRP in the sepsis group were all higher than those in the healthy control group ( Z=-2.99, -5.42, -4.95, -4.09, -5.05, -11.30, -8.66, -8.23, -5.64, -4.75, -2.12 and -10.75, respectively, all P<0.05). The differences were statistical significance. The levels of IL-2 ( r=0.149, P=0.037), IL-6 ( r=0.223, P=0.002), IL-8 ( r=0.159, P=0.026), and IL-10 ( r=0.188, P=0.009) in patients with sepsis were positively correlated with SOFA scores. The AUC of CRP in diagnosing sepsis was 0.989 with the sensitivity of 97.4% and the specificity of 100.0%. The AUC of IL-6 in diagnosing sepsis was 0.953, with the sensitivity of 93.3% and the specificity of 97.1%, and the AUC of IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-8, IL-10, IL-12P70, IL-17A, and TNF-α were 0.620, 0.718, 0.699, 0.665, 0.703, 0.850, 0.836, 0.727, 0.691, and 0.574, respectively.The AUC of the 11 cytokines were all lower than that of CRP, and the differences were all statistically significant ( Z=2.34, 10.24, 8.03, 8.08, 10.64, 8.70, 5.91, 5.17, 8.91, 9.25 and 4.10, respectively, all P<0.05).During the dynamic monitoring, the IFN-γ and IL-1β levels in the non-survival group increased gradually. The IFN-γ levels on the 14th and 21st day in the non-survival group were higher than those in the survival group ( Z=0.53 and 0.08, respectively, both P<0.05), and IL-1β levels on the 14th, 21st, and 28th days were also higher than those in the survival group ( Z=0.03, 0.26 and 0.31, respectively, all P<0.05). IL-6 and IL-8 levels reached their peaks on the 14th day, which were significantly higher than those in the survival group ( Z=0.01 and 0.02, respectively, both P<0.05), and then decreased, and the differences were all statistically significant. Conclusions:The levels of IFN-γ and IL-1β in the non-survival sepsis patients show a gradually increasing trend. The dynamic changes of IL-6 have certain significance for the prediction of disease severity and prognosis evaluation in sepsis.
