BACKGROUND Research on the combined use of ear acupoint embedding beans and warming meridians with cold-dispersing formulas for alleviating resting pain in patients with arteriosclerosis obliterans(ASO)remains limited.AIM To explore the therapeutic efficacy of auricular point embedding beans combined with Wenjing Sanhan prescription in alleviating resting pain in patients with lower-limb ASO.METHODS A total of 100 patients with ASO experiencing resting pain who were treated at our hospital from January 2022 to January 2023 were enrolled.They were randomly allocated into two groups using a double-blind approach.The control group was treated using a warming meridian with a cold-dispersing formula,while the study group received additional treatment with ear acupoint embedding beans.The clinical efficacy,ankle-brachial artery pressure ratio,hemorheological indicators,and traditional Chinese medicine symptom scores were compared between the two groups.RESULTS The clinical efficacy rate in the study group was significantly higher(94.00%)than that in the control group(72.00%,P<0.05).Moreover,the ankle-brachial artery pressure ratio was significantly higher in the study group after treatment(P<0.05).Hemorheological parameters,including whole blood viscosity,plasma viscosity(1.83±0.11)mPa/s,fibrinogen levels(3.30±0.21)g/L,platelet adhesion rate(49.87%±10.51%),and erythrocyte aggregation index(1.79±0)were improved in the study group compared to the control group.In addition,the scores for decreased skin temperature(1.41±0.26),intermittent claudication(1.30±0.20),and resting pain(1.23±0.31)were significantly lower in the study group than those in the control group(all P<0.05).The level of oxidative stress in the study group also exhibited significant improvement(P<0.05),and the levels of inflammatory factors were considerably lower than those in the control group.CONCLUSION The combination of ear point embedding beans and Wenjing Sanhan prescription demonstrates promising clinical efficacy in alleviating resting pain associated with ASO.

Analysis of the Effect of Problem-Oriented Nursing Intervention on Patients with Lower Extremity Arteriosclerosis Obliterans in Vascular Surgery

Objective: To analyze the effect of problem-oriented nursing intervention on patients with lower extremity arteriosclerosis obliterans (ASO) in vascular surgery. Methods: The clinical data of 128 patients with lower extremity ASO in vascular surgery were selected and randomly divided into groups A and B, with 64 cases each. Group A is the control group, and Group B is the observation group. Group A received the routine nursing intervention, and Group B received the problem-oriented nursing intervention. The compliance, self-care ability, psychological state, quality of life, and nursing satisfaction of the two groups of patients were evaluated based on various indicators. Results: After the intervention, the evaluation of self-care ability (ESCA) score of the patients in Group B was higher than that of Group A, and the symptom checklist-90 (SCL-90) score was lower than that of Group A. The differences were significant (t = 10.019, t = 3.118, P < 0.01). After the intervention, the World Health Organization Quality of Life Brief (WHOQOL-BREF) index scores of the two groups increased and the increase in Group B was significantly higher than Group A (P < 0.001). The compliance rate of Group B (62/ 96.88%) was higher than that of Group A (52/ 81.25%), and the difference was extremely significant (χ2 = 8.020, P < 0.01). Conclusion: Problem-oriented nursing intervention for patients with lower extremity ASO in vascular surgery improved the patient’s self-care ability, and quality of life, reduced the patient’s negative emotions, and enhanced their overall satisfaction.

Advances in the management of arteriosclerosis of the lower extremity:Integrating Western and Chinese medicine approaches

This editorial provides a commentary on the recent article.The paper reviews current literature and explores innovative treatment strategies for lower extremity arteriosclerosis obliterans(LEASO)through an integrative approach.It highlights the effectiveness of combination therapies that merge traditional Chinese medicine(TCM)with Western medical practices,suggesting that such integrative methods may improve patient compliance and outcomes through personalized care.This paper stresses the importance of rigorous clinical trials to evaluate the efficacy and safety of TCM interventions within LEASO treatment protocols,advocating for evidence-based validation of these combined therapies.Our recommendations emphasize accurate diagnosis,appropriate pharmacological in-terventions,the use of advanced surgical and endovascular techniques,and the inclusion of TCM to address underlying dysfunctions.Additionally,continuous monitoring,patient education,and lifestyle modifications are essential to slow disease progression and achieve optimal patient outcomes.The paper concludes by calling for further research to develop standardized treatment protocols that effectively integrate both Western and Chinese medical approaches in managing LEASO.

Clinical and prognostic features in asymptomatic and symptomatic patients with arteriosclerosis obliterans

Background: Patients with arteriosclerosis obliterans (ASO) often have co-existing atherosclerotic diseases. The purpose of this study was to examine the clinical features of patients with ASO, including the overlap of atherosclerotic risk factors, characteristics of car-diovascular events, and clinical prognosis. Method: We enrolled 205 consecutive patients who had ankle brachial index (ABI) of ?0.9 between January 2008 and December 2009. Fontaine (F) classification and clinical background were evaluated and clinical events including mortality and major adverse cardiocerebro-vascular events (MACCEs) were determined. Results: There was a high prevalence of each risk factor. Sixty- five percent of subjects had three or more of the four overlapping risk factors, including hypertension, dia- betes, dyslipidemia, and smoking. After a maximum follow-up of 800 days, the incidence of MACCEs and mortality was 46% and 10%, respectively. We divided the patients into two groups according to the presence of ASO symptoms (F1 and F2-4) and compared the incidence of events. The incidence of MACCEs and mortality in the F2-4 group was significantly higher than that in the F1 group (P = 0.048, P = 0.044, respectively). After excluding lower extremity revascularization, coronary artery disease was a common cause of MACCEs, and the mortality rates after MACCEs increased in a stepwise manner according to F classification severity (P = 0.028). Conclusion: Patients with ASO had overlapping coronary risk factors and a high incidence rate of cardiovascular events. The incidence of coronary events was common, especially in symptomatic patients, and the mortality rates after MACCEs were high in accordance with F classification severity.

目的探讨CT血管造影(CTA)对下肢动脉硬化闭塞症(ASO)介入治疗效果评估及术后复发预测价值。方法选择130例ASO患者,其中男性81例,女性49例;年龄50~67岁,平均年龄58.92岁(标准差5.04岁);身体质量指数(BMI)21~27 kg/m^(2),平均BMI 24.28 kg/m^(2)(标准差1.33 kg/m^(2));高血压51例,糖尿病56例,冠心病57例;吸烟85例。均给予介入手术治疗及CTA检查,比较手术前后下肢动脉狭窄程度、斑块参数[斑块负荷(PB)、斑块面积(PA)、最小管腔面积(MLA)]。对所有患者进行为期1年的随访,根据ASO是否复发,分为复发组和未复发组,比较两组斑块参数,绘制受试者工作特性(ROC)曲线,计算曲线下面积(AUC),分析PB、PA、MLA对ASO复发的预测价值。Logistic回归分析ASO复发的危险因素。结果术后中度狭窄(23.08%)、重度狭窄(19.23%)、完全闭塞率(3.08%)均低于术前(30.77%、46.15%、13.85%)(P<0.05)。术后PB、PA、MLA均低于术前[(29.82±4.11)%vs(62.82±8.16)%、(4.26±0.26)mm^(2)vs(9.26±1.33)mm^(2)、(3.01±0.17)mm^(2)vs(7.16±1.05)mm^(2)。P<0.05]。随访1年后,根据复发情况分为复发组28例和未复发组102例。复发组PB(57.63±4.28)%、PA(9.02±1.27)mm^(2)、MLA(6.96±1.01)mm^(2)均高于未复发组[(28.11±3.85)%、(4.07±1.07)mm^(2)、(2.85±0.12)mm^(2)。t=35.077、20.805、40.474,P<0.05]。PB、PA、MLA联合检测预测ASO复发的AUC是0.792[95%可信区间(CI)0.716~0.954],灵敏度、特异度分别是93.08%、91.13%,均高于单一检测(P<0.05)。高血压、糖尿病、血管闭塞长度、术后用药不规律、C反应蛋白(CRP)是ASO复发的危险因素(P<0.05)(OR=1.268、1.216、1.134、1.329、1.226;95%CI=1.135~1.438、1.128~1.395、1.034~1.296、1.162~1.468、1.133~1.429)。结论CTA可准确评估ASO患者下肢动脉狭窄程度,辅助临床评估治疗效果,提高对疾病复发的预测灵敏度及特异度,ASO的复发与多种因素有关,应当引起临床重视与关注。

血管减压联合药物涂层球囊对股腘动脉硬化性闭塞症患者早期疗效及其机制分析

目的探讨血管减压联合药物涂层球囊对股腘动脉硬化性闭塞症患者早期疗效及其机制。方法选择2020年1月至2022年5月于合肥市第一人民医院就诊的82例股腘动脉硬化性闭塞症患者为研究对象。采用随机数字表法将患者分为对照组(n=41,行药物涂层球囊治疗)与观察组(n=41,行血管减压联合药物涂层球囊治疗)。比较两组患者临床疗效、动脉硬化相关指标、血流动力学参数、血小板活化因子水平及并发症发生情况。结果观察组患者总有效率为92.69%(38/41),高于对照组患者的75.61%(31/41),差异均有统计学意义(P﹤0.05)。治疗后,两组患者股腘动脉内中膜厚度、脉搏波传导速度均低于本组治疗前,且观察组患者股腘动脉内中膜厚度、脉搏波传导速度均低于对照组患者;治疗后,两组患者踝臂血压指数均高于本组治疗前,且观察组患者踝臂血压指数高于对照组患者,差异均有统计学意义(P﹤0.05)。治疗后,两组患者全血黏度、血浆黏度、纤维蛋白原水平均低于本组治疗前,且观察组患者全血黏度、血浆黏度、纤维蛋白原水平均低于对照组患者,差异均有统计学意义(P﹤0.05)。治疗后,两组患者可溶性CD40配体、sP选择素均高于对照组患者,且观察组患者可溶性CD40配体、sP选择素均高于对照组患者,差异均有统计学意义(P﹤0.05)。两组患者并发症发生率比较,差异无统计学意义(P﹥0.05)。结论血管减压联合药物涂层球囊治疗较单独行药物涂层球囊治疗可有效提高股腘动脉硬化性闭塞症患者早期疗效,改善患者动脉硬化相关指标、血流动力学参数,但却在一定程度上导致血小板活化因子水平升高。
