目的:建立广西地不容中延胡索乙素、巴马汀和青藤碱含量测定方法.方法:以HypersilODS2柱(4.6 mm×250 mm,5μm)为色谱柱,流动相:乙腈-0.5％磷酸水溶液,梯度洗脱,检测波长:282 nm,流速:1.0 mL·min-1,柱温:30℃,进样量:10 μL.结果:延胡索乙素、巴马汀、青藤碱分别在0.135～1.35 mg·mL-1、0.032,98～0.329,8 mg·mL-1、0.031,24～0.312,4 mg· mL-1范围内线性关系良好,r=0.999,9.结论:该方法准确、可靠,可用于广西地不容药材及相关制剂中生物碱类成分的含量测定.

OBJECTIVE:To establish HPLC fmgerprints of Stephania kwangsiensis.METHODS:HPLC method was adopted.The determination was performed on Hypersil ODS2 with mobile phase consisted of acetonitrile-0.5％ phosphoric acid (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelength was set at 282 nm,and column temperature was 30 ℃.The sample size was 10 μL.Using tetrahydropalmatine as reference,HPLC fingerprints of 10 batches of medicinal materials were determined.Common peak identification and similarity evaluation were conducted by using Similarity Evaluation System of TCM Chromatographic Fingerprint (2012 edition).RESULTS:A total of 17 common peaks were identified in HPLC fingerprints of 10 batches of S.kwangsiensis.Among 10 batches of samples,fingerprint of samples from 8 producing areas were compared with control chromatogram.The similarity was higher than 0.900.The similaritg of samples from 2 producing areas were lower than 0.900.CONCLUSIONS:Established HPLC fingerprint can provide reference for the identification and quality evaluation of S.kwangsiensis;S.kwangsiensis in Guangxi from most producing areas include similar alkaloid components,but samples from other producing areas are different from them.

目的:观察合并完全性右束支传导阻滞(CRBBB)的急性前壁心肌梗死(AAMI)的临床特点.方法:回顾性分析316例AAMI患者,将合并新发CRBBB患者43例作为观察组,50例不合并束支传导阻滞的AAMI患者作为对照组,分析两组患者一般资料、冠状动脉造影、心脏彩超、Killip分级以及血液生化指标的差异.结果:两组患者一般情况及并发症比较无明显差异(P>0.05),平均Killip分级观察组为1.63±0.93,对照组为1.22±0.62(P=0.013).左室射血分数(LVEF)观察组为(41.6±4.2)%,对照组为(48.2±4.4)%(P=0.001).肌酸激酶同工酶(CKMB)峰值观察组为(276.6±63.5)U/L,对照组为(171.5±29.4)U/L(P<0.001).肌钙蛋白I峰值(TNI)观察组为(11.01±2.39)μg/L,对照组为(6.03±1.52)μg/L(P<0.001).冠脉造影结果观察组前降支近段病变(26/43,60.5%),对照组前降支近段病变(15/50,30%)(P=0.003).结论:合并CRBBB的AAMI患者多为前降支近段病变,心肌梗死面积更大、心功能更差,应对这些患者尽早采取再灌注治疗以改善预后.

识别冠心病高危患者并对其预测预后,进而采取针对治疗,一直是医学研究的关注焦点.随着研究深入,使用自主神经功能指标对冠心病患者进行危险分层的方法逐渐受到人们所重视.
