摘要:

目的 分析板蓝根、连翘、黄芩、蒲公英单独使用和与头孢哌酮-舒巴坦(SCF)联合应用对广泛耐药(XDR)鲍曼不动杆菌(AB)的抑菌作用。方法 收集2018年9月—2019年10月北京中医药大学第三附属医院30株XDR-AB非重复临床分离株。采用微量肉汤稀释法测定板蓝根、连翘、黄芩、蒲公英单用和与SCF联用对30株XDR-AB的最小抑菌浓度(MIC)。计算4种中药与SCF联用的分级抑菌浓度(FIC)指数。比较4种中药作用于XDR-AB后菌液K+和碱性磷酸酶(ALP)水平的变化。结果 4种中药均有一定抑菌作用,其中连翘和黄芩MIC较低。板蓝根与SCF联用效果较好,以协同作用和相加作用为主。连翘、黄芩与SCF联用多表现为拮抗作用(FIC指数>2)。4种中药作用于XDR-AB后,菌液K+水平变化差异无统计学意义(P>0.05);连翘、黄芩作用于XDR-AB后,菌液ALP活性增强(P<0.05);板蓝根、蒲公英作用于XDR-AB前后菌液ALP活性差异无统计学意义(P>0.05)。结论 连翘和黄芩单独使用的抑菌效果较好,板蓝根与SCF联用抑菌效果最好。临床可根据实际情况合理用药,以达到最佳效果。

Abstract:

Objective To analyze the antibacterial effects of Radix isatidisForsythiaScutellaria baicalensis and Dandelion and combined with cefoperazone-sulbactam(SCF) for extensively drug-resistant Acinetobacter baumannii(XDR-AB). Methods Totally,30 isolates of XDR-AB were collected from clinical specimens from September 2018 to October 2019 in the Third Affiliated Hospital of Beijing University of Chinese Medicine. The minimum inhibitory concentrations(MIC) of Radix isatidisForsythiaScutellaria baicalensis and Dandelion alone and combined with SCF to 30 isolates of XDR-AB were determined by broth microdilution method. Fractional inhibitory concentrations(FIC) were calculated. The changes of K+ and alkaline phosphatase(ALP)levels of 4 Chinese herbal medicines were compared. Results The 4 Chinese herbal medicines have certain antibacterial effects. The MIC of Forsythia and Scutellaria baicalensis were low. The effect of Radix isatidis combined with SCF was good,and synergistic and additive effects were predominant. The effects of Forsythia and Scutellaria baicalensis combined with SCF were mainly antagonism(FIC index >2). The K+ levels of the 4 groups were not statistically significant(P>0.05). The ALP levels in Radix isatidis and Dandelion groups were not statistically significant(P<0.05),and those in Forsythia and Scutellaria baicalensis groups were not statistically significant(P>0.05). Conclusions The antibacterial effects of Forsythia and Scutellaria baicalensis are good,the combined antibacterial effect of Radix isatidis and SCF is opitmal.
