Atherosclerosis (AS) is a common underlying disease that hazard to human health.It is closely associated with stroke,hypertension,coronary artery disease,and diabetes.AS on the premise of vascular intimnal injury,excessive smooth muscle cell proliferation,inflammatory cell infiltration,oxidative stress,apoptosis and other mschanisms participate together.In eucaryotic organisms,most proteins are degraded by ubiquitin-proteasome system (UPS).An increasing number of evidence indicates that UPS is associated with the occurrenee and development of AS and complications.This article reviews the relationship between.UPS and AS,as well as the effect of ubiquitin-proteasome inhibitor on AS.

Objective To investigate the relationship between omentin-1,aquaporin 4(AQP4),and visinin-like protein 1(VILIP-1)levels and vascular recanalization after emergency endovascular treatment in patients with acute large vessel occlusion stroke(ALVOS)and their combined predictive efficacy.Methods In total,110 patients with ALVOS undergoing emergency endovascular treatment were categorized into a non-reopening group(23 patients)and a reopening group(87 patients)based on whether the blood vessels were re-opened after surgery.Clinical data and omentin-1,AQP4,and VILIP-1 levels were compared between the two groups.Factors influencing postoperative blood vessel reopening were analyzed,and nomograms were drawn to evaluate their predictive performance and calibration.Results Significant differences were observed in the proportion of patients with hypertension;preoperative NIHSS scores;emergency blood glucose;AQP4,VILIP-1,omentin-1,and platelet levels;time from onset to endovascular treatment;preoperative ASPECTS;and proportion of patients undergoing intravenous thrombolysis between the two groups(P＜0.05).Preoperative ASPECTS and omentin-1 levels were independent protective factors associated with postoperative vascular recanalization,whereas the time from onset to endovas-cular treatment,preoperative NIHSS scores,and AQP4 and VILIP-1 levels were independent risk factors associated with postoperative vascular recanalization(P＜0.05).The C-index of the nomogram for predicting postoperative vascular recanalization was 0.994,and the AUC of the nomogram for predicting postoperative vascular recanalization was 0.994,with a calibration degree of 0.975.Conclusion Omentin-1,AQP4,and VILIP-1 levels are important factors affecting vascular recanalization in patients with ALVOS after emergency endovascular treatment.Clinically,monitoring these levels may help to predict and evaluate early vascular recanalization fol-lowing treatment.

ObjectiveTo observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke. MethodsA prospective study was conducted on 160 patients with post-stroke dysphagia， who were randomly divided into a treatment group and a control group， with 80 cases in each group. The control group received conventional rehabilitation training， while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan （CV 23） on the basis of conventional rehabilitation training， for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment， and assessed the swallowing function including videofluoroscopic swallowing study （VFSS）， standardized swallowing assessment （SSA） and functional oral intake scale （FIOS）， swallowing contrast test including hyoid maximum displacement （HmaxD）， pharyngeal transit time （PTT）， and upper esophageal sphincter （UES） opening， surface electromyography （sEMG） test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire （SWAL-QOL） score of the patients in both groups before treatment， after 2 weeks and 4 weeks of treatment， respectively. ResultsThe total effective rate in treatment group was 82.50% （66/80）， significantly higher than 66.25% （53/80） in control group （P＜0.05）. The VFSS， and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment （P＜0.05）， while SSA scores， PTT， and swallowing duration were decreased compared within group before treatment （P＜0.05）. VFSS and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher （P＜0.05）， while SSA scores， PTT， and swallowing duration were lower （P＜0.05） than those in the control group at the same time. ConclusionCombined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke can significantly improve swallowing activities， and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.
