Objective To explore the therapeutic effect of Yiqi Tongyang Granule in the treatment of immune thrombocytopenia mice and the underlying mechanism.Methods BALB/c mice were treated with anti-mouse platelet serum from guinea pig to establish an immune thrombocytopenia mouse model. Model mice were randomly devided into the model group, the prednisone group, the Yiqi Tongyang Granule group, and the Jinshuye group; 10 unmodeled mice as the control group. The mice were treated with Yiqi Tongyang Granule(17.4 g/kg), prednisone(9.1 mg/kg), and Jinshuye Styptic Mixture(3.9 mL/kg) by gavage for 11 days, and the platelets(PLT), white blood cells(WBC), and hemoglobin(Hb) counts in the mice were measured. Bone marrow megakaryocyte counts were compared by bone marrow smears and bone marrow pathology, and the proportions of different types of megakaryocytes in bone marrow were analyzed. The organ coefficients and pathological changes of the spleen and thymus were observed in mice. Lymphocyte subsets were detected using a flow cytometer.Results Compared with the control group, the number of PLT in immune thrombocytopenia mice was reduced(P<0.05), and after treatment with Yiqi Tongyang Granule, prednisone, and Jinshuye Styptic Mixture, the number of PLT was increased(P<0.05). Compared with the control group, the number of bone marrow megakaryocytes was increased and the proportion of PLT-producing megakaryocytes was decreased in immune thrombocytopenia mice(P<0.05). The number of megakaryocytes was decreased after treatment with Yiqi Tongyang Granule(P<0.05), the ratio of primitive and naive megakaryocytes was decreased, and the proportion of PLT-producing megakaryocytes was increased in the immune thrombocytopenia mice(P<0.05). The spleen was observed to be enlarged in the immune thrombocytopenia mice based on the spleen organ coefficient and pathology, and extramedullary hematopoiesis was found to be common in the spleens of immune thrombocytopenia mice. Thymus atrophy was very obvious in immune thrombocytopenia mice treated with prednisone based on the thymus organ coefficient and pathology. The percentages of Tc, Th, and Treg cells of immune thrombocytopenia mice were reduced, and these percentages were increased after treatment with Yiqi Tongyang granules(P<0.05).Conclusion Yiqi Tongyang Granule could regulate the immune state of immune thrombocytopenia mice by regulating the lymphocyte subpopulations and increase the PLT levels in peripheral blood by affecting the number of bone marrow PLT-producing megakaryocytes. The therapeutic effect of Yiqi Tongyang Granule was similar to that of prednisone and clearly superior to that of Jinshuye Styptic Mixture.
微小残留病(minimal residual disease,MRD)是急性白血病(acute leukemia,AL)经诱导化疗达到完全缓解后体内残留微量白血病细胞的状态,成为AL复发的根源,加强对MRD阳性患者的治疗是提高患者整体生存的关键.麻柔主任医师提出AL以阴寒凝滞为基本病机,诱导化疗药物可戕害人体阳气,亦可导致髓不化血,因此MRD以阴寒凝滞兼血虚阳衰为主要病机.麻柔主任医师常以当归四逆汤化裁治疗MRD,本方功可温经通阳散寒,兼以养血和血,有助于机体清除或者抑制MRD,维持MRD的阴性状态,并促进部分患者的MRD由阳性转为阴性,临证屡获良效.本文就麻柔主任医师应用当归四逆汤化裁治疗MRD的临床经验和体会进行论述,以期指导MRD的中医治疗.
Objective To explore the potential molecular target and mechanism of Qinghuang Powder in the treatment of myelodysplastic syndrome(MDS).Methods Fifteen MDS patients were enrolled in this study.Bone marrow samples were extracted before treatment and 6 months after treatment with Qinghuang Powder, and RNA-seq was performed to detect the differentially expressed genes(DEGs)in bone marrow mononuclear cells before and after treatment.Gene ontology(GO)annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment were performed for the DEGs.Cytoscape 3.9.1 was employed to build the protein-protein interaction(PPI)network of DEGs.Furthermore, the MDS cell line MUTZ-1 was treated with arsenic sulfide, the main effective component of Qinghuang Powder, and then real-time quantitative PCR was employed to verify the RNA-seq results.Results A total of 2 841 DEGs were identified by RNA-seq in bone marrow nucleated cells of MDS patients treated with Qinghuang Powder for 6 months, including 1 892 up-regulated genes and 949 down-regulated genes.GO annotation showed that these DEGs were mainly involved in histone modification highly associated with MDS.KEGG pathway enrichment indicated that Qinghuang Powder treated MDS via the hypoxia-inducible factor-1(HIF-1),tumor necrosis factor-alpha(TNF-α),and vascular endothelial growth factor(VEGF)signaling pathways.According to GO annotation results, the DEGs associated with histone modification were used to construct the PPI network, from which the core genes were screened out.The MDS cells treated with arsenic sulfide showed significantly up-regulated expression of E1A binding protein p300(EP300),histone deacetylase 7(HDAC7),and SET domain-containing protein 2(SETD2)and down-regulated expression of HDAC6,which was consistent with the sequencing results.Conclusion Histone modification is an important step of Qinghuang Powder in the epigenetic regulation of MDS patients.EP300,HDAC6,HDAC7,and SETD2 may be the key targets of Qinghuang Powder in the treatment of MDS.

Purpose DNA methylation is known to play an important role in myelodysplastic syndrome (MDS). We previously showed that Chinese herbs (CHs) containing realgar (As2S2) were effective at treating MDS with multilineage dysplasia (MDS–MLD). We tested whether the response to CH treatment was related to changes in DNA methylation in MDS–MLD. Patients and Methods First, the Illumina methylation 850K array BeadChip assay was used to assess the pretreatment methylation status in bone marrow cells from eight MDS–MLD patients and 3 healthy donors. The eight MDS–MLD patients were then treated with CHs for six months, the arsenic concentration was measured following treatment. The patients were subsequently divided into “effective” and “ineffective” treatment response groups and the DNA methylation patterns of the two groups were compared. Finally, the BeadChip data were validated by pyrosequencing. Results Five of the eight MDS–MLD patients showed hematological improvement (effective-treatment group), while three showed disease progression (ineffective-treatment group) (positive response rate: 62.5%). The arsenic concentrations in the patients ranged from 26.60 to 64.16 μg/L (median 48.4 μg/L) and were not significantly different between the two groups (p = 0.27). Compared with the healthy controls, three genes were hypomethylated and 110 were hypermethylated in the ineffective-treatment group. However, in the group showing hematological improvement, 102 genes were markedly hypomethylated and 87 hypermethylated. The effective-treatment group had a higher proportion of hypomethylated sites than the ineffective-treatment group (53.9% vs 2.6%, respectively; chi-square test) (p < 0.0001). Two hypermethylated and two hypomethylated genes were selected for validation by pyrosequencing (all p < 0.05). Conclusion MDS–MLD patients may present different DNA methylation subtypes. CHs containing realgar may be effective for treating MDS–MLD patients with the hypomethylation subtype.

OBJECTIVE:To explore the relationship between the efficacy of realgar for the treatment of myelodysplastic syndromes with multilineage dysplasia (MDS-MLD) and arsenic concentration in the peripheral blood of patients.METHODS:In this prospective study, a total of 50 MDS-MLD patients were treated with traditional Chinese drugs containing realgar for 3 months in Xiyuan Hospital from March 2018 to January 2019. Routine blood examination as well as liver and kidney function were monitored before and after treatment. The concentration of arsenic in the peripheral blood was measured using an atomic fluorescence spectrometer after treatment. The correlation between clinical effect and arsenic concentration was analyzed by Spearman's method.RESULTS:The treatment response rate was 54%. Two patients (4% ) achieved complete remission, 50% (25 of 50) showed hematologic improvement, and 23 patients had stable disease (23% ). No disease progression was observed. Arsenic concentration in the peripheral blood ranged from 14.60 to 85.96 μg/L. Clinical efficacy was positively correlated with arsenic concentration (P < 0.05). The incidence of mild adverse reactions was 16%.CONCLUSION:A relatively high concentration of arsenic in the peripheral blood may improve the clinical efficacy of realgar in MDS-MLD patients.
Traditional Chinese Medicine (TCM) is a practical medicine based on thousands of years of medical practice in China. Arsenic dispensing powder (ADP) has been used as a treatment for MDS patients with a superior efficacy on anemia at Xiyuan Hospital of China Academy of Chinese Medical Sciences. In this study, we retrospectively analyzed MDS patients that received ADP treatment in the past 9 years and confirmed that ADP improves patients’ anemia and prolongs overall survival in intermediate-risk MDS patients. Then, we used the MDS transgenic mice model and cell line to explore the drug mechanism. In normal and MDS cells, ADP does not show cellular toxicity but promotes differentiation. In mouse MDS models, we observed that ADP showed significant efficacy on promoting erythropoiesis. In the BFU-E and CFU-E assays, ADP could promote erythropoiesis not only in normal clones but also in MDS clones. Mechanistically, we found that ADP could downregulate HIF1A in MDS clones through upregulation of VHL, P53 and MDM2, which is involved in two parallel pathways to downregulate HIF1A. We also confirmed that ADP upregulates GATA factors in normal clones. Thus, our clinical and experimental studies indicate that ADP is a promising drug to promote erythropoiesis in both MDS and normal clones with a superior outcome than current regular therapies. ADP promotes erythropoiesis in myelodysplastic syndromes via downregulation of HIF1A and upregulation of GATA factors.
再生障碍性贫血(aplastic anemia,AA)主要分为重型(severe AA,SAA)和非重型再生障碍性贫血(non-severe AA,NSAA)两类.AA属于中医“髓劳”范畴,SAA和NSAA分别归属于“急髓劳”和“慢髓劳”.SAA和输血依赖性NSAA(TD-NSAA)的中西医结合治疗疗效确切,结合近期再生障碍性贫血的临床进展和治疗体会,提出SAA多处于以“细胞因子风暴”为典型特征的“异常免疫”阶段,此阶段以异常免疫为主要矛盾,以骨髓衰竭为次要矛盾,应以免疫抑制剂+中药补肾活血解毒为主治疗,TD-NSAA所处阶段多以骨髓衰竭为主要矛盾,治疗应以补肾健脾中药+雄激素为主促进骨髓造血功能恢复.连续治疗6个月无效的TD-NSAA应根据SAA中西医结合治疗方案进行治疗.
