Table 1.

Evaluation of the histological pathological score.

Score	Epithelial cells	Inflammatory cell infiltration
0	Normal form	No infiltration
1	Goblet cell loss	Infiltration in the basal layer of the crypt
2	Large area loss of goblet cells	Infiltration reaches the mucosal muscle layer
3	Crypt cell loss	Infiltration deep into the mucosal muscle layer, accompanied by mucosal thickening and edema
4	Large area loss of crypt cells	Infiltration to the submucosa
