Objective To investigate the effect of 3D rotational digital subtraction angiography(DSA)-guided drug balloon predilation bare-metal stents on vertebral artery origin stenosis(VAOS).Methods A total of 63 VAOS patients who were admitted to Hai'an People's Hospital from May 2020 to December 2022 were selected and divided into two groups according to different treatment methods.There were 16 males and 14 females with a mean age of(52.10±3.62)years in the observation group.There were 19 males and 14 females with a mean age of(52.47±3.85)years in the control group.There was no statistical difference in the basic data between the two groups(P>0.05).The observation group was treated with 3D rotational DSA-guided drug balloon predilation bare-metal stent,while the control group was treated with conventional drug balloon predilation bare-metal stent.The efficacy of the two groups was compared.Results The success rate of operation was 100%(30/30)in the observation group,which was higher than that in the control group(96.97%[32/33],χ2=0.924,P=0.336).There was no significant difference in the stenosis rate between the two groups either before surgery or 3 months after surgery(P>0.05).The hemodynamic level of the initial segment of vertebral artery in the observation group was lower than that in the control group 3 months after surgery(P<0.05).The scores of neurological function and quality of life at 3 months after surgery and the incidence of recurrent stroke at 6 months after surgery in the observation group were lower than those in the control group(P<0.05).Restenosis occurred in 2 cases(6.67%)in the observation group and 9 cases(27.27%)in the control group,and there was significant difference in the incidence of restenosis between the two groups(χ2=4.630,P=0.031).Conclusion 3D rotational DSA-guided drug balloon predilation bare-metal stent can effectively reduce the stenosis rate and the incidence of restenosis,and improve the nerve function and the quality of life of VAOS patients.

ObjectiveTo observe the efficacy and safety of Uyghur medicine Yangxin Dawayimixike Honey Paste （养心达瓦依米西克蜜膏， YDMHP） in the treatment of stable angina pectoris （SAP） of qi stagnation and blood stasis syndrome. MethodsA randomized ， double-blind， positive-controlled，multi-center clinical trial was conducted， in which 370 patients with SAP of qi stagnation and blood stasis syndrome were randomly divided into treatment group（279 cases）and control group（91cases）at a ratio of 3∶1. The treatment group was orally administered with YDMHP， 3 g each time， and placebo of Xuefu Zhuyu Capsule （血府逐瘀胶囊）， 2.4 g each time， while the control group was treated with Xuefu Zhuyu Capsule， 2.4 g each time， and placebo of YDMHP， 3 g each time， both twice a day for a course of 12 weeks. The primary outcome was the effect of angina pectoris symptom. The secondary outcomes include single angina symptom scores such as number of attacks， duration of attacks， pain intensity and usae of nitroglycerin scores， the total angina symptom score before and after the treatment， the usage of nitroglycerin， the exercise duration in treadmill exercise test （TET） and the Duck treadmill score among patients，the scores of Seattle Angina Questionnaire （SAQ） on five dimensions including physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception， and efficacy of TCM syndrome and of each single TCM symptom after treatment. The safety were evaluated by examine blood routine， urine routine， liver and kidney function， fasting blood sugar， electrocardiogram， adverse events. ResultsThe total effective rate of angina symptom in the treatment group was 71.69% （200/279）， significantly higher than 51.64% （47/91） in the control group （P＜0.01）. The curative and markedly effective rate of TCM syndrome in the treatment group was 53.05% （148/279）， which was significantly higher than 25.27% （23/91） in the control group （P＜0.01）. After treatment， scores of the number as well as duration of angina attacks and pain severity， the total score of angina symptoms， and the usage of nitroglycerin significantly decreased in both groups， and more changes were seen in the treatment group than in the control group； the scores of physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception in both groups significantly increased， and more improvement were shown in the experimental group regarding the anginal stability， anginal frequency and treatment satisfaction （P＜0.05 or P＜0.01）. The effects of chest pain， chest tightness， palpitation， shortness of breath and fatigue in experimental group were significantly higher than those in control group （P＜0.05 or P＜0.01）. There was no significant difference in the exercise duration of treadmill test and Duke score among patients between the two groups either before or after treatment （P＞0.05）. Adverse events occurred in 66 cases （23.66%） of the experimental group and 16 cases （17.58%） of the control group， with no statistical significance between the two groups （P＞0.05）. ConclusionThe Uyghur medicine YDMHP can effectively improve symptoms of angina pectoris， reduce the number， duration， and intensity of attacks， decrease the dosage of nitrogly-cerin and improve the individual TCM symptoms and has good safety in the treatment of SAP patients of qi stagnation and blood stasis.
