Objective To analyze the effects of intravenous tirofiban following endovascular treatment on the prognosis of patients with acute anterior circulation large vessel occlusion stroke who did not achieve successful recanalization.Methods This retrospective study included consecutive patients with acute anterior circulation ischemic stroke who underwent endovascular treatment but did not achieve successful recanalization.These patients were retrospectively enrolled from the Department of Neurology at Nanjing Jinling Hospital,Affiliated Hospital of Medical School,Nanjing University,the Second Affiliated Hospital of Soochow University,Wuhan No.1 Hospital,and Yijishan Hospital of Wannan Medical College(the First Affiliated Hospital of Wannan Medical College)between January 2015 and April 2023.Baseline and clinical data were collected including age,sex,medical history(hypertension,diabetes,atrial fibrillation,hyperlipidemia),personal history(smoking and drinking),National Institutes of Health stroke scale(NIHSS)score at admission,trial of Org 10172 in acute stroke treatment(TOAST)classification(large artery atherosclerosis,cardioembolism,or other types),Alberta stroke program early CT score(ASPECTS)on admission,intravenous thrombolysis,onset-to-puncture time(OTP),collateral circulation status(poor collaterals:American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASTIN/SIR]score 0-2;good collateral:ASTIN/SIR score 3-4),procedure duration(from femoral or radial artery puncture to device removal),occlusion site,number of passes for thrombus retrieval,and post-procedural modified thrombolysis in cerebral infarction(mTICI)grade.Patients were divided into a tirofiban group and a non-tirofiban group based on whether they received post-procedural intravenous tirofiban.The primary outcome is a favorable functional outcome at 90-day since onset(modified Rankin scale[mRS]score ≤ 3).Safety outcomes included mortality at 90-day since onset(mRS score 6),any intracranial hemorrhage within 24 h post-procedure,and symptomatic intracranial hemorrhage within 24 h post-procedure.1∶1 propensity score matchings using the nearest neighbor method was performed based on variables with P＜0.05 in the comparison between the tirofiban and non-tirofiban groups.Differences in primary and safety outcomes between the matched groups were compared.Univariate and multivariate Logistic regression analyses were conducted with favorable outcomes at 90 days as the dependent variable to evaluate the effect of intravenous tirofiban administration after endovascular therapy on 90-day prognosis in patients without successful recanalization.Results A total of 356 patients without successful recanalization after endovascular treatment were included,comprising 195 males and 161 females,with a median age of 70(61,78)years(32-92 years).Among them,76 and 280patients were assigned to the tirofiban and non-tirofiban groups,respectively.At 90 days,114 patients had favorable outcomes,while 242 had unfavorable outcomes.(1)Before the 1∶1 propensity score matching,significant differences were observed between the tirofiban and non-tirofiban groups in terms of admission NIHSS score,ASPECTS,good collateral circulation,intravenous thrombolysis,and mTICI grade(all P＜0.05).After 1∶1 propensity score matching,66 matched pairs(132 patients)were obtained.No significant differences in the baseline and clinical characteristics were found between the two groups after matching(all P＞0.05).(2)After 1∶1 matching,a significant difference was observed in the rate of favorable outcomes at 90 days between the two groups(48.5％[32/66]vs.30.3％[20/66],P=0.033)after propensity score matching,while no significant differences were found in 90-day mortality,intracranial hemorrhage within 24h,or symptomatic intracranial hemorrhage within 24h(all P＞0.05).(3)Univariate analysis after 1∶1 matching indicated that age,atrial fibrillation,smoking history,admission NIHSS score,M2 segment middle cerebral artery occlusion,good collateral circulation,number of passes for thrombus retrieval,and tirofiban treatment were factors influencing favorable outcomes at 90 days.Multivariate Logistic regression analysis showed that younger age(aOR,0.942,95％CI 0.906-0.978,P=0.002),lower admission NIHSS score(aOR,0.855,95％CI 0.777-0.941,P=0.001),good collateral circulation(aOR,5.534,95％CI 2.141-14.301,P＜0.01),tirofiban treatment(aOR,2.774,95％CI 1.092-7.046,P=0.032),and M2 segment MCA occlusion(reference:internal carotid artery occlusion;aOR,4.874,95％CI 1.428-16.632,P=0.011)were independent predictors of favorable outcomes at 90 days.Conclusions Intravenous tirofiban administration after endovascular therapy may improve 90-day neurological outcomes in patients with acute anterior circulation large vessel occlusion stroke who did not achieve successful recanalization without increasing the risk of hemorrhage.Further large-scale randomized controlled trials are warranted to validate these findings.

Objective To explore the clinical application effects of Chen's pancreatojejunostomy in laparoscopic pancreaticoduodenectomy.Methods Clinical data of 176 patients who underwent laparoscopic pancreaticoduodenectomy in Xiangyang Central Hospital from January 2019 to December 2024 were retrospectively analyzed.According to the methods of intraoperative pancreatojejunostomy,the patients were divided into two groups,the research group(102 cases)using Chen's pancreatojejunostomy,and the control group(74 cases)using duct-to-mucosa pancreatojejunostomy.The two groups were compared on clinical indicators,including operation time,pancreatojejunostomy time,intraoperative blood loss,incidence of postoperative complications,length of hospital stay,and 30-day postoperative mortality rate.Results All 176 patients successfully underwent laparoscopic pancreaticoduodenectomy.There were no statistically significant differences between the two groups in intraoperative blood loss,biochemical leakage,abdominal bleeding,upper gastrointestinal bleeding,delayed gastric emptying,bile leakage,abdominal infection,and 30-day postoperative mortality rate(P＞0.05).The pancreatojejunostomy time[(22.33±5.95)min]and operation time[(334.60±66.42)min]in the study group were significantly shorter than those in the control group[(30.70±5.50)min]and[(414.46±60.96)min],with statistically significant differences(P＜0.05).Two groups of patients did not develop grade C pancreatic fistula.The incidence of grade B pancreatic fistula in the study group(5.88％)was significantly lower compared to the control group(16.22％),and this difference was statistically significant(P＜0.05).Additionally,The postoperative hospital stay of the study group patients[(17.10±6.89)days]was significantly shorter than in the control group[(20.88±8.40)days],with a statistically significant difference(P＜0.05).Conclusion Chen's pancreatojejunostomy is a feasible,safe,and effective procedure in laparoscopic pancreaticoduodenectomy,which can shorten the pancreatojejunostomy time,reduce the incidence of postoperative pancreatic fistula,and decrease the length of hospital stay.

Objective To investigate the clinical efficacy of wrapping the hepatic artery with the hepatogastric ligament for preventing bleeding of the hepatic artery and its branches following pancreaticoduodenectomy(PD).Methods 194 patients who underwent PD in Xiangyang Central Hospital from January 2017 to November 2024 were enrolled and categorized into two groups based on whether the hepatic artery was enwrapped with the hepatogastric ligament during the operation.The wrapped group consisted of 95 cases where the hepatic artery was wrapped,while the non-wrapped group had 99 cases without such wrapping.Intraoperative parameters(intraoperative blood loss and operative time)and postoperative complications(pancreatic fistula,abdominal cavity infection,biliary fistula,delayed gastric emptying,postoperative bleeding,and bleeding of the hepatic artery and its branches)were compared between the two cohorts.Univariate and multivariate Logistic regression analyses were conducted to identify the independent risk factors for postoperative bleeding.Results PD was accomplished successfully in both groups.There was no remarkable difference in intraoperative indices like blood loss and operative time between the two groups(P＞0.05).Similarly,no significant disparities were noted in postoperative complications such as pancreatic fistula,abdominal infection,biliary fistula,and delayed gastric emptying(P＞0.05).Nevertheless,the incidence of postoperative bleeding in the wrapped group was lower than that in the non-wrapped group(3.16％vs.12.12％,P=0.019),and the incidence of bleeding of the hepatic artery and its branches after surgery was also significantly decreased in the wrapped group(0 vs.10.10％,P=0.004).Logistic regression analysis revealed that the operation time(OR=1.013,P=0.011),pancreatic fistula(OR=9.006,P=0.006)and celiac infection(OR=7.930,P=0.014)are independent risk factors of postoperative bleeding,Hepatogastric ligament encapsulation of hepatic artery was an independent protective factor for postoperative hemorrhage of PD(OR=0.084,P=0.006).Conclusion Wrapping the hepatic artery with the hepatogastric ligament reduces PD postoperative bleeding,especially that of the hepatic artery and its branches,without adding other complications.

Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Aim To systematically investigate the ac-tive components,targets,and regulatory pathways of Po-lygonum capitatum in intervening atherosclerosis(AS)through network pharmacology,molecular docking and animal experiments.Methods Active components of Polygonum capitatum and AS-related targets were screened and identified through database searches.Protein-protein interaction(PPI)network analysis was performed using the STRING database,followed by GO and KEGG enrichment analyses via the David plat-form.Molecular docking validation was conducted with AutoDock.An AS model was established in Syrian golden hamsters fed a high-fat diet.Predicted pathways and targets were validated using qPCR,ELISA,and histopathological assessment of aortic and hepatic tis-sues via HE staining.Results Network pharmacology identified 27 potential active components of Polygonum capitatum(primarily flavonoids such as quercetin and luteolin)and 110 drug-disease intersection targets,in-cluding core targets MMP-9,ALB,and AKT1.GO and KEGG analyses enriched 593 and 125 pathways,re-spectively,with the NF-κB inflammatory pathway,TNF signaling pathway and lipid metabolism/atherosclerosis pathways highlighted as key mechanisms.Animal ex-periments demonstrated that Polygonum capitatum im-proved serum lipid profiles(reduced TC,TG,LDL-C)in AS hamsters,suppressed the MMP-9/NF-κB signa-ling pathway(downregulated MMP-9,p65 phosphoryla-tion,TNF-α,and IL-6),and inhibited VSMC synthetic phenotypic transformation(upregulated α-SMA and myocardin)by downregulating MCPIP1.Additionally,Polygonum capitatum ameliorated aortic lesions and he-patic lipid deposition in AS hamsters.Conclusions Polygonum capitatum alleviates AS by synergistically regulating the MMP-9/NF-κB/MCPIP1 axis through flavonoid components,suppressing vascular inflammato-ry cascades and maintaining VSMC contractile pheno-types.This reflects Polygonum capitatum's multi-com-ponent,multi-pathway,and multi-target characteristics in combating AS.
