目的:探讨心脑宁胶囊对冠心病经皮冠状动脉介入(PCI)术后心绞痛患者的影响。方法:选取2021年5月至2022年3月河北省中医院心血管科收治的冠心病PCI术后合并不同程度心绞痛的患者132例作为研究对象,按照简单随机化(抛硬币)法分为对照组和观察组,每组66例,均给予常规西药治疗,对照组给予安慰剂治疗,观察组给予心脑宁胶囊口服。比较2组患者治疗前后心绞痛发作情况及硝酸甘油减停率、血脂、斑块面积、西雅图心绞痛量表评分以及不良反应。结果:治疗24周后,2组患者心绞痛发作情况、硝酸甘油减停率、三酰甘油、总胆固醇、低密度脂蛋白胆固醇水平均较治疗前明显改善,且观察组更显著(均P<0.05)。2组患者治疗后躯体活动受限程度,心绞痛稳定状态,心绞痛发作情况,治疗满意程度及疾病认知程度均改善(均P<0.05)。结论:心脑宁胶囊联合西药短期治疗冠心病PCI术后心绞痛患者,可减少心绞痛发作次数,缩短心绞痛发作时间,减少抗心绞痛药物用量,有效控制血脂水平,且不良反应少。

The age, growth, and mortality of Gymnocypris firmispinatus were studied by 582 individuals that collected between July 2015 and June 2016 from the tributaries of the Anning River, China. The total length (TL) ranged from 27 mm to 242 mm, total weight (W) ranged from 0.2 g to 148.2 g. The relationship of total length and weight was expressed as W =7.754×10^-6 TL^ 3.304 for the total samples. The age classes of males were 1–9 a, and that of females were 1–13 a. The von Bertalanff y functions based on otolith readings and observed length data were L t ♂=198.6(1–e^-0.094 ( t +3.497)), and L t ♀=289.3(1–e^-0.089 ( t +1.109)). The total mortality ( Z ) of male and female G . firmispinatus was estimated as 0.73/a and 0.40/a, respectively. The natural mortality ( M ) was evaluated as 0.25/a for males and 0.20/a for females, fishing mortality ( F ) was 0.35/a for males and 0.16/a for females. The exploitation ratio of the population was 0.66/a for males and 0.50/a for females. It was concluded that the growth of the fish is relatively slower than other congeneric fishes. The population of G . firmispinatus in the tributaries of the Anning River might be in over-exploitation under the current fishing intensity.
