OBJECTIVETo observe the clinical efficacy of a low dose Qinghuang Powder (QP) combined with Chinese drugs for Shen supplementing and Pi invigorating (CDSSPI) in treatment of hypocellular myelodysplastic syndromes (hypo-MDS).

METHODSTotally 33 hypo-MDS patients enrolled in this study came from outpatient clinics between November 2011 and December 2012. A self-control method was used in this study. Patients took QP (0.4 g per day) combined with CDSSPI (one dose per day), and Stanozolol Tablet (2 mg each time, three times per day), 3 months as one therapeutic course, a total of 2 courses. The clinical efficacy was evaluated timely at the end of each therapeutic course. The venous blood was withdrawn before treatment, at month 3 and 6 after treatment. Changes of neutrophils (ANC), hemoglobin (Hb), and platelet (PLT) were mainly observed.

RESULTSTotally 31 patients in this study finished the treatment. Three months after treatment ANC, Hb, and PLT increased more than before treatment (P < 0.05). Six months after treatment Hb and PLT increased (P < 0.01, P < 0.05), but with no statistical difference in ANC (P > 0.05). Hb increased higher at month 6 after treatment than at month 3 after treatment (P < 0.01), but with no statistical difference in ANC or PLT (P > 0.05). After 3-month treatment the number of hematologic progress, stability, disease progression were: 13 cases (41.9%), 15 cases (48.4%), and 3 cases (9.7%), respectively; after 6-month treatment the number of hematologic improvement, stability, and disease progression were: 18 cases (58.1%), 7 cases (22.6%), 6 cases (19.3%), respectively. There was no significant difference between 3-month efficacy and 6-month efficacy (P > 0.05). There was no correlation between the efficacy and ages of hypo-MDS patients or the efficacy and courses of hypo-MDS patients (P > 0.05).

CONCLUSIONSA low dose QP combined with CDSSPI showed confirmative efficacy in treatment of hypo-MDS. But the efficacy had little correlation with ages and courses of hypo-MDS patients.
