Effect of Chinese Herbal Medicine Therapy on Risks of Overall, Diabetes-Related, and Cardiovascular Diseases-Related Mortalities in Taiwanese Patients With Hereditary Hemolytic Anemias

Hereditary Hemolytic Anemias (HHAs) are a rare but heterogeneous group of erythrocytic diseases, characterized by intrinsic cellular defects due to inherited genetic mutations. We investigated the efficacy of Chinese herbal medicine (CHM) in reducing the overall, diabetes-related, and cardiovascular diseases (CVDs)-related mortalities among patients with HHAs using a nationwide population database. In total, we identified 33,278 patients with HHAs and included 9,222 non-CHM and 9,222 CHM matched pairs after matching. The Cox proportional hazards model was used to compare the risk of mortality between non-CHM and CHM users. The Kaplan-Meier method and log-rank test were used to compare the cumulative incidence mortality between non-CHM and CHM users. The CHM prescription patterns were presented by the association rules and network analyses, respectively. The CHM prescription patterns were presented by the association rules and network analyses, respectively. CHM users showed significant reduced risks for of overall (adjusted hazard ratio [aHR]: 0.67, 95% confidence interval [CI]: 0.61-0.73, p < 0.001), diabetes-related (aHR: 0.57, 95% CI: 0.40-0.82, p < 0.001), and CVDs-related (aHR: 0.59, 95% CI: 0.49-0.72, p < 0.001) mortalities compared with non-CHM users. Two CHM clusters are frequently used to treat Taiwanese patients with HHAs. Cluster 1 is composed of six CHMs: Bei-Mu (BM; Fritillaria cirrhosa D.Don), Gan-Cao (GC; Glycyrrhiza uralensis Fisch.), Hai-Piao-Xiao (HPX; Endoconcha Sepiae), Jie-Geng (JG; Platycodon grandiflorus (Jacq.) A.DC.), Yu-Xing-Cao (YXC; Houttuynia cordata Thunb.), and Xin-Yi-Qing-Fei-Tang (XYQFT). Cluster 2 is composed of two CHMs, Dang-Gui (DG; Angelica sinensis (Oliv.) Diels) and Huang-Qi (HQi; Astragalus membranaceus (Fisch.) Bunge). Further randomized clinical trials are essential to evaluate the safety and effectiveness of above CHM products and to eliminate potential biases in the current retrospective study.

Clinical Effect and Mechanism of Yisui Shengxue Granules in Thalassemia Patients with Mild, Moderate, or Severe Anemia

Yisui Shengxue granules, which is a Chinese traditional medicine, can increase hemoglobin, red blood cells, and Ret of thalassemia patients with mild, moderate, and severe anemia and thus relieve clinical anemia symptoms. Studies on mechanism found that Yisui Shengxue granules can increase the proliferation ability of hematopoietic stem cells. Emodin promoted colony forming of hematopoietic stem cells. Yisui Shengxue granules can increase the activity of GSH-PX in bone marrow blood and decreased the severity of inclusion bodies on the cytomembrane of RBCs. YSSXG attenuated anemia symptoms in patients with thalassemia mostly by increasing the proliferation of hematopoietic stem cells and decreasing the hemolysis of RBCs.

Molecular mechanism of yisui shengxue granule, a complex chinese medicine, on thalassemia patients suffering from hemolysis and anemia of erythrocytes

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 ^Aγ-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.

Effect of Yisui Shengxue Granule () on the oxidative damage of erythrocytes from patients with hemoglobin H disease

OBJECTIVE

To investigate the effect of Yisui Shengxue Granule (, YSSXG), a complex Chinese medicine, on the oxidative damage of erythrocytes from patients with hemoglobin H (HbH) disease.

METHODS

Twenty-two patients with HbH disease and 22 healthy volunteers were observed. YSSXG was given to patients with HbH disease for 3 months. Before and after the 3-month treatment, blood parameters [hemoglobin (Hb), red blood cells (RBCs), and reticulocyte percent (Ret)] were examined; inclusion bodies in erythrocytes were observed by transmission electron microscopy (TEM); activities of antioxidant defense enzymes [superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (Cat)] and erythrocyte membrane malondialdehyde (MDA) concentrations were determined.

RESULTS

In patients with HbH disease, measured values of RBC and Hb obtained from the first to the third months after treatment with YSSXG were significantly higher than before treatment (P<0.01). Measured values of Ret from the second to the third months after treatment were significantly lower than before treatment (P<0.05 and P<0.01, respectively). Prior to treatment with YSSXG, TEM images of RBCs showed the presence of numerous inclusion bodies. After treatment with YSSXG, the amount and volume of inclusion bodies decreased. Treatment with YSSXG also led to a significant increase in SOD activity (P<0.01), a decrease in Cat activity (P<0.01), and no significant differences in GSHPx activity (P>0.05) or MDA concentration (P>0.05). However, compared with the healthy counterparts, SOD, GSH-Px, and Cat activities presented at high levels (P<0.01) both before and after treatment.

CONCLUSIONS

YSSXG could improve the degree of hemolysis and anemia in patients with HbH disease. The mechanism may be related to its antioxidative effects, which could elevate the activity of total SOD in erythrocytes and efficiently inhibit the oxidative precipitation of β-globin chains.
