摘　　要：目的:探究富血小板血浆(platelet-rich plasma,PRP)及其与抗生素头孢呋辛钠联合应用在体外对大肠埃希菌的作用。方法:从六安市中心血站获取健康志愿者捐献的血小板作为PRP来源。将一定浓度的大肠埃希菌质控菌株与PRP及抗生素头孢呋辛钠共同培养,观察PRP单独应用及与抗生素头孢呋辛钠联合应用时的抑菌情况。结果:2 mg/L头孢呋辛钠在12 h内无抑菌作用,4 mg/L头孢呋辛钠可在24 h内发挥抑菌作用,8 mg/L头孢呋辛钠可在48 h内发挥较强抑菌作用。PRP单独应用可以在24 h内发挥抑菌作用,与2 mg/L头孢呋辛钠联合应用在12 h内可抑制大肠埃希菌生长,与4 mg/L头孢呋辛钠联合应用在24 h内可抑制大肠埃希菌生长,与8 mg/L头孢呋辛钠联合应用在36 h内可抑制大肠埃希菌生长。结论:PRP单独应用在体外可抑制大肠埃希菌的生长,与抗生素联合应用可发挥抑菌作用,并减轻抗生素的使用剂量。Objective To investigate the effect of platelet-rich plasma(PRP)and its combination with cefuroxime sodium on Escherichia coli in vitro.Methods Apheresis platelets donated by healthy volunteers were obtained from the Blood station of Lu'an Blood Center as the source of PRP.In order to explore the antibacterial effect of PRP alone or in combination with cefuroxime sodium,a certain concentration of Escherichia coli quality control strains were co-cultured with PRP and cefuroxime sodium.Results 2 mg/L cefuroxime sodium had no antibacterial effect within 12 hours,4 mg/L cefuroxime sodium had antibacterial effect within 24 hours,and 8 mg/L cefuroxime sodium had strong antibacterial effect within 48 hours.The application of PRP alone could exert antibacterial effect within 24 hours,the combination with 2 mg/L cefuroxime sodium could inhibit the growth of Escherichia coli within 12 hours,the combination with 4 mg/L cefuroxime sodium could inhibit the growth of Escherichia coli within 24 hours,and the combination with 8 mg/L cefuroxime sodium could inhibit the growth of Escherichia coli within 36 hours.Conclusion Platelet-rich plasma alone could inhibit the growth of Escherichia coli in vitro,and combined with antibiotics could exert bacteriostatic effect and reduce the dosage of antibiotics.
