Background. MicroRNA-33a and -b miR-33a-b have been revealed to be posttranscriptional regulators of HDL metabolism. Xuezhikang XZK is a marked natural HDL-raising polypill. We aim to evaluate the effects of XZK on the expression of circulating miR-33a-b in patients with low plasma HDL-C levels. Methods. A total of 42 participating patients with low baseline levels of HDL cholesterol were assigned to receive an XZK capsule, 600 mg twice daily for 6 months. The expression of circulating miR-33a-b was detected at baseline and after XZK therapy measured with quantitative reverse-transcription RT polymerase chain reaction PCR. Results. The mean SD HDL-C level after XZK treatment was 1.19 0.13 mmol-L, representing an increase of 11.2% from baseline . Q-PCR analysis of plasma miRNAs revealed an increase in relative miR-33a-b expression with XZK treatment. The miR-33a expression was raised from 0.81 to 1.73 ; miR-33b expression was increased from 1.2 to 2.75 . The changes of miR-33a and miR-33b were inversely related to the posttreatment LDL-C levels , ; , , resp

Conclusion. In patients with low HDL-C levels, XZK therapy raised plasma levels of miR-33a and miR-33b, which may inhibit cellular cholesterol export and limit the HDL-raising effect of XZK.
