Effects of puerarin on the expression of P2X3 mRNA in PBMCs were detected by RT-PCR. a The expression of P2X3 receptors mRNA in NS and PUE group was higher than that in the healthy control group (p < 0.01). The expression of P2X3 mRNA in group PUE d2 and PUE d3 was significantly lower than that in PUE d1 (p < 0.01) and significantly lower than that in NS group(p < 0.01), although still higher than that in the healthy control group (p < 0.01). b **p < 0.01, compared with Healthy group (control); ## p < 0.01, compared with NS-treated group in histogram
