Methods: Two hundred patients with chronic thrombocytopenia were randomly divided into control (n=100) and test groups (n = 100) with Amino-polypeptide as a basic treatment for both. Test group patients consumed a blood-increasing decoction and blood-generating powder for 1-3 months. Improvements in platelet counts and TCM syndrome were observed. Results: One hundred and sixty-four (80 in the test group and 84 in the control group) of 189 total participants were treated for 3 months. The total effective rate in improving TCM syndrome was 95.00% in the test group and 79.76% in the control group (P<0.05). There was significant difference (P<0.05) in the accumulated score of TCM syndrome between the two groups treated at different time points. The total effective rate of platelet counts was 86.25% in the test group and 59.52% in the control group (P<0.05). There was a significant difference in platelet counts before and after treatment in the two groups (P<0.05). There was no significant differences in platelet count between the two groups treated for 1-2 months; however, a significant difference was found between the two groups after treatment for 3 months (P<0.05). Conclusions: After a 3-month treatment of chronic thrombocytopenia patients with qi-supplementing and yin-nourishing therapy, TCM syndrome was improved and platelet counts increased with no obvious side effects, and the quality of life of the participants was enhanced with noticeable long-term curative effects.展开更多
