BACKGROUND Most studies on Guhong injection have involved a single center with a small sample size,and the level of clinical evidence is low.AIM To assess the safety and efficacy of Guhong injection for mild ischemic stroke(IS).METHODS A total of 399 IS patients treated at six hospitals from August 2018 to August 2019 were retrospectively analyzed.The patients were given Guhong injection(experimental group)or Butylphthalide injection(control group).Changes in National Institutes of Health Stroke Scale(NIHSS)and modified Rankin Scale(mRS)scores were observed before treatment and at 1,2,and 3 wk after treatment in each group.The efficacy and safety of Guhong injection for IS were assessed.Other medications taken by the patients were confounding factors for efficacy assessment.These factors were controlled by propensity score matching,and the results were further analyzed based on the matching.RESULTS The marked response rates at three follow-up visits were 64.64%,74.7%,and 66.7%in the experimental group,and 48.26%,45.4%,and 22.2%in the control group.The marked response rates increased significantly in the experimental group compared with the control group(P<0.05).The overall response rate at the first visit(days 7±2)did not differ significantly between the two groups,but differed significantly at the second(days 14±2)and third visits(days 21±3)(P<0.05).The proportion of patients without any symptoms in the experimental group was significant different at the first visit(P<0.05),but not significantly different at the second visit.The two groups showed no significant difference in the baseline distribution of mRS scores.At the first and second visits,the change in mRS scores was-2 and-1 in the experimental and control groups,respectively,which were significantly different(P<0.05).After propensity score matching,the overall response rate and marked response rate were 97.29%and 100%in the experimental group(P>0.05)and 64.0%and 47.7%in the control group(P<0.05)at the first visit,respectively.The decreased NIHSS scores in the two groups were significant different(P<0.05).The overall response rate and marked response rate differed significantly between the two groups at the second visit(P<0.05).There was no significant difference in the incidence of adverse events between the two groups.No severe adverse events occurred in either group.CONCLUSION Guhong injection is safe and more effective than Butylphthalide injection for treatment of IS. 展开更多

This study used an anodic etching(AE)method to construct a hierarchical rough surface on the surface of the Cu-bearing antibacterial titanium alloy,Ti-xCu(x=3,5,7 wt%),a three-dimensional structure with nested micro-/submicro-pores and internal cavities,which is conducive to the adhesion and growth of bone cells.After AE treatment,with increase of the Cu content in the alloy,the surface of Ti-Cu alloy became sharper,with more fine micropores and internal cavities,thus increasing the surface area.The results indicated that the AE/Ti-Cu alloy exhibited good antibacterial properties and had the effect of inhibiting bacterial biofilm formation.AE treatment could increase the Cu ions release of Ti-Cu alloy in saline,and the higher the Cu content in the alloy,the more Cu ions release,resulting in stronger antibacterial performance of the alloy.AE/Ti-Cu alloy showed excellent biocompatibility,similar to the pure Ti.Therefore,anodic etching is a safe and effective surface treatment method for Ti-Cu alloy,with good clinical application prospects. 展开更多
