Yangzheng Sanjie decoction regulates proliferation and apoptosis of gastric cancer cells by enhancing let-7a expression

Table 3 Let-7a and c-Myc expression in gastric cancer tissue samples

Tissue	Let-7a					c-Myc
	(-)	(+)	(++)	(+++)	P value	(-)	(+)	(++)	(+++)	P value
Ca	3	7	1	0	< 0.05	0	2	4	5	< 0.05
Pc	0	8	3	0		1	6	3	1
N	0	1	6	4		4	6	1	0

Staining intensity was described as negative (-), weak (+), moderate (++) and strong (+++) staining. Ca: Gastric cancer tissues; Pc: Matched para-carcinoma tissues; N: Matched distal normal gastric tissues.
