Groups	Cases (n)	PAR-2 (n)				PAR-2 positive rate (%)
		Negative (-)	Weakly positive (+)	Moderately positive (++)	Strongly positive (+++)
NGM	59	46	6	5	2	22.03
GWDAC	8	2	1	3	2	75.00*
GMDAC	29	3	4	5	17	89.66*
GPDAC	104	6	13	27	58	94.23*
LMGAC	53	3	4	12	34	94.34*

NGM, normal gastric mucosa; GWDAC, well-differentiated gastric adenocarcinoma; GMDAC, moderately differentiated gastric adenocarcinoma; GPDAC, poorly differentiated gastric adenocarcinoma; LMGAC, lymph node metastasis adenocarcinoma. *Compared with normal gastric mucosa, P=0.0418.
