Table 2. Comparison of the average optical density of PCNA in the isthmus and the base in gastric glands of rats in each group.

Groups	Isthmus	Base
Control	0.010±0.001	0.005±0.002
Model	0.004±0.000**	0.016±0.002**
Positive drug	0.009±0.000#	0.005±0.002##
JPYQF-L	0.011±0.001##	0.005±0.001##

Values were expressed as mean ± SD. Compared with the same area of control group, **, P<0.01; compared with the same area of model group, ^#, P<0.05, ^##, P<0.01. All experiments were repeated 3 times. JPYQF-L, Jian-Pi-Yi-Qi-Fang low-dose group; JPYQF-M, Jian-Pi-Yi-Qi-Fang middle-dose group; JPYQF-H, Jian-Pi-Yi-Qi-Fang high-dose group.
