本文对96例婴幼儿腹泻患者,在发病早期或极期,进行大便培养和连续空肠弯曲菌直接涂片检查后,分为细菌性或非细菌性(包括病毒和非感染因素) 二组,全组病人均作外周血涂片,瑞氏染色,油镜下作中性粒细胞计数,并计算其中杆状核与中性粒细胞总数的比率(以B/N 表示),从而初步发现,细菌性肠炎组杆状核明显升高,并发现B/N 的升高与肠道感染并存,感染控制后其比率随之降低,经统计学处理后认为B/N>27%时可诊为细菌性肠炎,B/N 在11～27%之间为可疑范围,并可将18%作为界值,再结合临床综合判定。本文认为B/N 虽不能作病原学诊断,但方法简单,可即时获得结果,对细菌性肠炎的初筛具有肯定的价值(P<0.01)
In this paper, 96 cases of infantile diarrhea in early onset or extreme stage, after stool culture and continuous jejunum Campylobacter smear direct examination, divided into bacterial or non-bacterial (including viral and non-infectious factors) two groups, all The patients were divided into peripheral blood smear, Wright’s stain, neutrophil count under the oil microscope, and the ratio of the total number of the tubercle nucleus to the neutrophil count (expressed as B / N) was calculated. It was initially found that the bacteria Enteritis group of tuberculous significantly increased, and found that elevated B / N and intestinal infection co-exist, infection control rate was reduced, after statistical treatment that B / N> 27% can be diagnosed as bacteria Enteritis, B / N between 11 to 27% of the suspicious range, and 18% as a cut-off value, combined with clinical comprehensive judgment. Although B / N can not be used for pathogenic diagnosis, the method is simple and can obtain the results immediately. It has a positive value for the preliminary screening of bacterial enteritis (P <0.01)
