Molecular Mechanism of Yisui Shengxue Granule, a Complex Chinese Medicine, on Thalassemia Patients Suffering from Hemolysis and Anemia of Erythrocytes

Abstract EN

The objective of this study was to investigate the therapeutic biological mechanism of Yisui Shengxue Granule (YSSXG), a complex Chinese medicine, on the hemolysis and anemia of erythrocytes from patient with thalassemia disease.

Sixteen patients with thalassemia (8 cases of α-thalassemia and 8 cases of β-thalassemia) disease were collected and treated with YSSXG for 3 months.

The improvements of blood parameter demonstrated that YSSXG had a positive clinical effect on patients with thalassemia disease.

For patients with α-thalassemia disease, RT-PCR showed that YSSXG upregulated the relative mRNA expression level of α-globin to β-globin and downregulated DNMT1, DNMT3a, and DNMT3b mRNA compared with pretreatment.

Western blotting showed that YSSXG downregulated the expression of DNMT1 and DNMT3a.

For patients with β-thalassemia disease, the relative expression level of A γ-globin to α-globin had an increasing trend and the level of BCL11A mRNA expression obviously increased.

For all patients, RT-PCR showed that YSSXG upregulated mRNA expression of SPTA1 and SPTB.

Activities of SOD and GSH-Px significantly increased and MDA obviously reduced on erythrocyte and blood serum after YSSXG treatment.

TEM showed that YSSXG decreased the content of inclusion bodies.

Activities of Na+K+-ATPtase and T-ATPtase of erythrocyte increased significantly after YSSXG treatment.

This study provides the basis for mechanisms of YSSXG on thalassemia suffering with hemolysis and anemia of erythrocytes from patient.
