1WONCA研究论文摘要汇编——建议冬季口服益生菌以减少应用抗生素治疗哮喘的随机对照试验显示文摘目的有研究表明儿童口服益生菌能预防呼吸道感染,从而可以减少抗生素的使用。本研究探讨了哮喘患者在冬季口服益生菌以减少应用抗生素治疗呼吸道感染的建议是否可行。方法本研究在英国1家社区医疗中心开展了随机对照试验。研究对象为5岁及以上的哮喘患者。干预措施是向哮喘患者发放传单,这种传单和普通的建议人们在冬季如何减少呼吸道感染或哮喘发作的传单不同,其内容为建议人们于2013年10月—2014年3月每日服用益生菌来减少这些疾病的发生。以研究对象中使用抗生素来治疗呼吸道感染的人数占总人数的比例作为评价结果的指标。结果 1 302例研究对象被随机分为对照组(n=650)和干预组(n=652)。干预组、对照组分别有27.7%、26.9%的患者应用了抗生素治疗呼吸道感染,两组间差异无统计学意义〔OR=1.04,95%CI(0.82,1.34)〕。服用益生菌量不多的患者在应用抗生素治疗呼吸道感染的人数比例上和对照组相比也相近〔调整后的OR=1.08,95%CI(0.69,1.69)〕。也未发现服用益生菌对治疗呼吸道感染或者哮喘急性发作有何作用。结论本研究中未发现有证据支持在冬季口服益生菌以减少使用抗生素来治疗呼吸道感染的建议。SMITH T D WATT H GUNN L 本刊编辑部 2016中国全科医学2016,19,34:11
2选择性头部降温对胎羊缺血性脑损伤纹状体神经元凋亡和星形胶质细胞增殖的影响显示文摘目的研究选择性头部降温对缺血性脑损伤胎羊纹状体神经元凋亡和星形胶质细胞增殖的影响。方法胎羊于妊娠117~124d时通过双侧颈动脉阻塞30min造成双侧脑缺血损伤,损伤后将胎羊随机分为:损伤组(n=10)、2h低温组(损伤后2h开始亚低温治疗,n=7)和6h低温组(损伤后6h开始亚低温治疗,n=8),另设正常对照组(n=5)。通过冷循环水进行选择性头部降温,取脑组织用免疫组化法检测胎羊纹状体caspase-3(半胱天冬氨酸酶-3),GFAP(胶质纤维酸性蛋白)和PCNA(增殖细胞核抗原)的表达。结果①纹状体神经元凋亡:正常对照组中,caspase-3表达极少(11.00±13.77),损伤组caspase-3免疫阳性细胞为177.70±48.69,明显增加(P=0.000),损伤后2h治疗组(54.14±39.44,P=0.000)和损伤后6h治疗组(122.43±52.36,P=0.017)均能减少caspase-3免疫阳性细胞。②纹状体星形胶质细胞增殖:与正常对照组(163.40±21.98)相比,缺血性脑损伤组的GFAP免疫阳性细胞明显增多(433.25±66.69,P=0.000),损伤后2h开始亚低温治疗(219.50±35.31,P=0.000)和损伤后6h开始亚低温治疗(272.50±86.20,P=0.000)均能减少GFAP免疫阳性细胞。③纹状体PCNA阳性细胞的表达:在正常对照组中,PCNA免疫阳性细胞较少,为153.40±12.46,缺血性脑损伤组的PCNA免疫阳性细胞明显增多(353.70±45.60,P=0.000),损伤后2h开始亚低温治疗(187.14±26.26,P=0.000)和损伤后6h开始亚低温治疗(230.25±67.46,P=0.000)均能减少PCNA免疫阳性细胞。结论亚低温可以抑制纹状体神经元的凋亡和星形胶质细胞的增殖,该作用可能为选择性头部降温的脑保护作用机制之一。骆菲 曹云 Guan J Gunn AJ Bennet L George S Gluckman PD 杨毅 陈莲 2007复旦学报(医学版)2007,34,4:2
