Methods: Thirty-five patients were enrolled, including 18 with "yang deficiency syndrome" and 17 with "yin deficiency syndrome." Bone marrow biopsies and serum were collected. Microvessel density (MVD) and positive expression of vascular endothelial-derived growth factor (VEGF) were detected by immunohistochemisty. Hypoxia inducible factor -α (HIF-α ), and VEGF expression were assayed by enzyme-linked immunoabsorbent assay (ELISA), serum lactate dehydrogenase (LDH) was tested by enzyme method and liquid chip technology was used to detected the expression of interleukin (IL)-2, IL-4, IL-6, IL-10, interferon (IFN)-'y and tumor necrosis factor (TNF)-α. Results: Counts for leukocytes, absolute neutrophils and platelets in "yin deficiency syndrome" were lower than those found in "yang deficiency syndrome" (P〈0.05). MVD and VEGF expression, and the positive rate of CD34 and VEGF in bone marrow were lower in hA, especially in "yin deficiency syndrome" (P〈0.01 or P〈0.05). "Yin deficiency syndrome" displayed decreased VEGF and LDH expression, and enhanced expression of HIF-α as compared to "yang deficiency syndrome" (P〈0.05). Levels of IL-4 and IL-6 were higher in AA (P〈0.01), but IL-10 was decreased (P〈0.05). High TNF-c~ expression was seen in "yang deficiency syndrome" and IFN- γ expression was decreased in "yin deficiency syndrome" as compared with normals (P〈0.01 and P〈0.05, respectively). Conclusion: AA patients have lower MVD than normals, especially in "yin deficiency syndrome." MVD might differentially correlate to disease severity, and could be dependent on bone marrow or serum VEGF expression and LDH. Additionally, IL-2, IL-10, IL-4 and IFN- γ were negatively associated while IL-6 and TNF- α were positively associated with MVD.展开更多

Methods: Sixty patients with CAA were randomly assigned to two groups equally, both were treated with Stanozolol three times a day, 2 mg each time through oral intake, but AI was given additionally to the patients in the treated group once a day via intravenous dripping. All were treated for 15 days as one therapeutic course and the whole medication lasted for more than 4 months totally, with follow-up adopted. The clinical efficacy was estimated and the changes of T-lymphocyte subsets in peripheral blood as well as the serum levels of tumor necrosis factor-α (TNF-α ) and interleukin-2 (IL-2) were observed. Results: The total effective rate in the treated group was 83.3% (25/30), which was higher than that in the control group 66.7% (20/30), showing significant difference between them (P〈0.05). Levels of hemoglobin, WBC, reticular cell and platelet were elevated in both groups after treatment, but the improvement was significantly better in the treated group than that in the control group with respect to the former three indexes (P〈0.05). The level of CD4^+ increased and that of CD8^+ decreased significantly after treatment in the treated group (P〈0.05), which showed significant difference as compared with those in the control group (P〈0.05). Levels of serum TNF-α and IL-2 lowered after treatment in both groups, but significance only showed in the treated group (P〈0.05). The degree of proliferation in bone marrow got raised significantly and the percentage of non-hemopoietic cells reduced significantly in the treated group after treatment, also showing significant difference to those in the control group (P〈0.05). Conclusion: AI could promote the recovery of hemopoietic function, which might be through improving T-lymphocyte subsets and reducing the release of negative regulatory factors such as TNF-α and IL-2 to alleviate the inhibition on hemopoietic function.展开更多
