^*Significant differences were observed compared with the control group and significant differences were observed among the groups of G-TCP0, G-TCP1 and G-TCP3 (p < 0.05)

^†Significant differences were observed compared with the control group, and significant differences were observed among the groups of G-TCP0, G-TCP1 and G-TCP3. Significant differences were also observed between eight weeks and four weeks after treatment (p < 0.05)

^‡Significant differences were observed among the control group, G-TCP0 group, G-TCP1 group and G-TCP3 group (p < 0.05)

^§Significant differences were observed compared with that of four weeks after treatment (p < 0.05), and significant differences were observed among the control group, G-TCP0 group, G-TCP1 group and G-TCP3 group (p < 0.05)

A paired t-test was used for all p-values
