Effect of tonifying qi and nourishing yin and cooling blood method on IL-10 and TGF-β in ITP model mice / 中国基层医药

ABSTRACT

Objective@#To explore the effects of Yiqi Yangyin Liangxue method on platelets, interleukin-10(IL-10) and transforming growth factor beta (TGF-β) of immune thrombocytopenic purpura(ITP) model mice, and to analyze its curative effect and possible mechanism.@*Methods@#A total of 100 ITP model mice were randomly divided into blank group, model group, single Chinese medicine group, single hormone group and Chinese medicine combined with hormone group.Drug intervention was started on the 8th day after the establishment of the model, and the drug was given for a total of 14 days.The blood of mice was collected and the levels of platelets, TGF-β and IL-10 in serum of mice in each group were detected.@*Results@#There was no statistically significant difference in platelet count among all groups before modeling(F=0.556, P>0.05). Before administration, there was statistically significant difference between the model group and the blank group (t=28.207, P<0.01), there were no statistically significant differences between the model group and the traditional Chinese medicine group, hormone group, hormone+ traditional Chinese medicine group (t=-1.96, -0.464, -0.979, all P>0.05). After gastric administration, the platelet counts in the traditional Chinese medicine group[(710.45±124.52)×109/L], hormone group[(768.10±127.42)×109/L], hormone+ traditional Chinese medicine group[(908.05±89.66)×109/L] were significantly higher than that in the model group[(413.55±38.84)×109/L](t=-10.18, -11.90, -22.63, all P<0.01). After gastric administration, there was no statistically significant difference between the traditional Chinese medicine group and the hormone group(t=-1.447, P>0.05). After gastric administration, the platelet count of the hormone+ traditional Chinese medicine group was significantly higher than that of the hormone group and the traditional Chinese medicine group(t=-4.017, -5.759, all P<0.01). There was statistically significant difference in IL-10 level among groups after administration(F=32.20, P<0.01). IL-10 levels between the model group[(20.28±0.75)ng/L] and traditional Chinese medicine group[(21.41±1.40)ng/L], hormone group[(21.79±1.14)ng/L] and traditional Chinese medicine+ hormone group[(23.14±1.34)ng/L] had statistically significant differences (t=-3.18, -4.93, -8.33, all P<0.01). There was no statistically significant difference between the traditional Chinese medicine group and hormone group(t=-0.927, P>0.05). There were statistically significant differences between the traditional Chinese medicine+ hormone group and traditional Chinese medicine group, hormone group (t=-3.97, -3.43, all P<0.01). There was statistically significant difference in TGF-beta level among all groups after administration(F=31.16, P<0.01). The TGF-β levels between the model group[(82.32±3.42)ng/L] and Chinese medicine group[(88.10±8.51)ng/L], hormone group[(90.03±4.50)ng/L] and Chinese medicine combined with hormone group[(94.41±2.53)ng/L] had statistically significant differences (t=-2.82, -6.10, -12.70, all P<0.01). There was no significant difference in TGF-β level between the Chinese medicine group and hormone group(t=-0.90, P>0.05). There were statistically significant differences in in TGF-beta level between the traditional Chinese medicine+ hormone group and Chinese medicine group, hormone group (t=-3.18, -3.79, all P<0.01).@*Conclusion@#Yiqi Yangyin Liangxue method can reduce platelet destruction by regulating the levels of IL-10 and TGF-β and inhibiting immunity, and it has good therapeutic effect on ITP.
