本文对1,592例活俭胃粘膜的上皮异型增生进行研究,将其分析为4个因素14个观察指标进行统计,并剖析病理分析过程中差异产生的原因。针对病理分级过程中客观与主观的模糊性,本文提出:组织学的五级法必须改成模糊五级法,使定级数值变为连续值,更加符合事物的客观情况。用随机抽样方法复查1,OOO块胃粘膜,误差率为4.7％,平均误差为0.325级,最大误差0.631级,大大减少了诊断误差。
In this study, 1,592 cases of epithelial dysplasia of the living mucous membranes were studied, and 14 factors were analyzed for the four factors, and the causes of differences in pathological analysis were analyzed. In view of the objectivity and subjective ambiguity in pathological grading process, this paper proposes that the five-level method of histology must be changed to a fuzzy five-level method, so that the grading value becomes a continuous value and is more in line with the objective situation of things. A random sampling method was used to review the 1,0OO gastric mucosa, with an error rate of 4.7%, an average error of 0.325, and a maximum error of 0.631, which greatly reduced the diagnostic error.
