Objective To evaluate clinical application of using Turbohawk atherectomy device in combination with drug-coated balloon in treatment of atreriosclerosis obliterans in lower extremity. Methods Turbohawk atherectomy device and DCB was performed in 8 patiments with atreriosclerosis obliterans in lower extremity. All patients were diagnosed by ultrasound and CTA. Routine anticoagulation drugs were used after the operation. Follow-up was carried out with color Doppler ultrasound. Results Revascularization was gained in 8 patients. The technically successful rate was 100% and ischemic symptoms relieved significantly immediately after the operation. The post-operative ankle brachinal index(ABI) was 0.78±0.06,which was higher than that of before operation(0.31±0.12). No obvious complications occurred after operation. The follow-up range was 3~18 months and limbs were salvaged successfully. Conclusion With minimal invasive, safe and few complications, Turbohawk atherectomy device in combination with drug-coated balloon is proved to be a very effective treatment atreriosclerosis obliterans in lower extremity and it is worth to popularize.

目的 探讨苯作业非酒精性脂肪肝工人丙氨酸氨基转移酶(ALT)水平与颈动脉粥样硬化的关系。方法 190名的苯作业非酒精性脂肪肝工人分为ALT异常组(ALT≥40 U/L)及ALT正常组(ALT＜40 U/L)。ALT异常组再根据ALT水平分为依据ALT水平分为G1组(60例,40 U/L≤ALT＜60 U/L),G2组(40例,60 U/L≤ALT＜80 U/L),G3组(35例, ALT＞80 U/L)。观察各组颈部动脉有否内膜增厚或斑块形成。结果 与ALT异常组颈动脉内膜增厚检出率和颈动脉斑块检出率明高于ALT正常组(P<0.05)。颈动脉内膜增厚检出率和颈动脉斑块检出率与ALT正常组相比较,G1组差异无统计学意义(P＞0.05), G2组有统计学意义(P<0.05),G3组有差异(P<0.01)。颈动脉内膜增厚检出率在G1组、G2组和G3组中逐渐增加,并有统计学意义(P<0.05)。G3组颈动脉斑块检出率与G1组比较,有差异(P<0.01)。结论 苯作业非酒精性脂肪肝工人中,血清ALT水平升高与颈动脉粥样硬化密切相关。ALT≥60 U/L的苯作业非酒精性脂肪肝人群更容易患颈动脉粥样硬化,应进行必要的预防和治疗。

Objective To explore the relationship between serum alanine aminotransferase levels(ALT) and carotid atherosclerosis in benzene exposed workers with nonalcoholic fatty liver disease. Methods 190 Benzene exposed workers with nonalcoholic fatty liver disease were enrolled divided into abnormal ALT group(n=135) and normal ALT group(n=55), the abnormal ALT group was further divided into three groups according to the levels of serum alanine minotransferase (ALT): group1(G1,60 subjects, 40 U/L≤ALT＜60 U/L),group2(G2,40 subjects, 60 U/L≤ALT＜80 U/L),and group3(G3,35 subjects, ALT＞80 U/L),observed if carotid has only thick endomembrane or with plaques. Results The rate of thick endomembrane of carotid and the detection rate of plaque in the abnormal ALT group are higher than those in the normal ALT control group (P<0.05). Compared with the normal ALT control group, no significant different was found in the rate of thick endomembrane of carotid and the detection rate of plaque in G1,but G2 was significantly different(P<0.05),G3 was extremely significantly different(P<0.01). The rate of thick endomembrane of carotid in G1,G2 and G3 increased, among the three groups. There were statistically significant differences in the rate of thick endomembrane of carotid(P<0.05). benzene exposed workers with nonalcoholic fatty liver disease in G3 showed extremely statistical differences on the detection rate of plaque compared to those in G1(P <0.01). Conclusion The increased level of ALT in benzene exposed workers with nonalcoholic fatty liver disease is closely related to carotid atherosclerosis. The benzene exposed workers with nonalcoholic fatty liver disease whose ALT≥60 U/L are apt to carotid atherosclerosis, should accept the necessary precaution and treatment.

目的 研究血浆脂蛋白磷脂酶 A2(Lp-PLA2)在防治急性动脉硬化性脑梗死中的临床价值。方法 选取2014年1月—2015年12月在我院经头颅MRI+MRA及脑血管造影确诊为急性动脉硬化性脑梗死患者80例为病例组,选取同期来我院例行体检头MRI+MRA 正常的健康自愿者40名为对照组。病例组采取脑梗死规范治疗及肢体功能康复锻炼,以酶联免疫法分不同时段测定两组患者血浆Lp-PLA2的浓度,以及评价病例组神经功能缺损程度,经数据分析研究脑梗死患者血浆Lp-PLA2浓度与神经功能缺损程度相关性。结果 急性动脉硬化性脑梗死患者血浆 Lp-PLA2浓度高于健康对照组患者,经统计学分析,P<0.05,并且随着脑梗死时间的推移,Lp-PLA2浓度愈低。NIHSS评分显示,随着脑梗死时间推移,NIHSS评分越来越低,差异有统计学意义(P<0.05)。对比同时期NIHSS评分和患者 Lp-PLA2浓度,NIHSS与Lp-PLA2浓度呈正相关(r=2.376,P<0.01)。结论 血浆Lp-PLA2 浓度升高是脑梗死的危险因素之一,降低血浆 Lp-PLA2 浓度可在脑梗死的早期预防上起到积极作用。

Objective To explore clinical value of plasma lipoprotein-associated phospholipase A2 (Lp-PLA2) in controlling acute atherosclerosis cerebral infarction. Methods 80 cases of acute atherosclerosis patients diagnosed by head MRI+MRA were selected as cases group, and 40 as normal controls. Cases treated with cerebral infarction specification therapy and lib function rehabilitation exercise. Using enzyme-linked immunoassay points at different times of measuring the concentration of plasma Lp-PLA2 in both groups, evaluating nerve function defect degree of cases, then analysis the correlation of cerebral infarction plasma concentration of Lp-PLA2 and neural function defect degree. Results Acute atherosclerotic cerebral infarction patients plasma concentration of Lp-PLA2 patients was significantly higher than healthy control group, by statistics analysis P<0.05, and with cerebral infarction time went by, the Lp-PLA2 concentration was lower. NIHSS score, with the time of cerebral infarction passed, was lower and lower, the change was statistically significant P<0.05.Compared with NIHSS score and concentration of Lp-PLA2, NIHSS and Lp- PLA2 concentration were positively correlated, r=2.376,P<0.01. Conclusion Plasma Lp-PLA2 is a risk factor for cerebral infarction. Reducing plasma concentration of Lp-PLA2 can play a positive role on the early prevention of cerebral infarction.
