OBJECTIVETo detect the variations in peripheral blood levels of autoantibodies, immunoglobulilns and complements in patients with non-lactational mastitis and investigate whether non-lactational mastitis is an autoimmune disease with immune dysfunction.

METHODSSeven-eight patients with non-lactational mastitis treated in our hospital between September 2013 and May 2015 and 88 healthy women (control) were examined for peripheral blood levels of antinuclear antibody (ANA), anti-histone antibody (AHA), immunoglobulins (IgA, IgM, and IgG) and complements (C3, C4, and total complements).

RESULTSs Of the 78 patients with non-lactational mastitis, 50 (64.10%) were positive of ANA showing mainly the granular and cytoplasmic granular fluorescence patterns, and the positivity rate was significantly higher than that in the control group (P<0.000). Twenty-eight (36.00%) of the patients were positive of AHA, a rate significantly higher than that in the control group (P<0.000). The levels of IgA, IgM, C4, and total complements levels were all significantly elevated in the patients compared with those in the control group (P<0.05).

CONCLUSIONPatients with non-lactational mastitis have abnormal changes in peripheral blood levels of immunoglobulins and complements with high positivity rates for ANA and AHA, indicating that non-lactational mastitis is an autoimmune disease with immune dysfunction.

OBJECTIVE: To explore the synergistic immunomodulatory mechanism of interferon alpha-1b, interleukin-2 and thalidomide (ITI) regimen on patients with acute myeloid leukemia (AML). METHODS: Sixty eight untreated de novo or relapsed or refractory or maintenance therapy patients with AML admitted in the Affiliated Cancer Hospital of Zhengzhou University and the other 11 medical units from March 2016 to May 2019 were treated with ITI regimen. Peripheral blood specimen per patient was collected into EDTA-K3 anticoagulation vacuum tube before the administration of ITI and 3 months after the treatment; peripheral blood lymphocyte subsets and perforin and Granzyme B expression were analyzed by using flow cytometry; the levels of VEGF, IFN-γ, TNF-α and IL-6 in the plasma were detected by using a cytometric bead array. Thirty-five healthy subjects from the hospital physical examination centre were selected as normal controls. RESULTS: The ratio of CD4 CONCLUSION The ITI regimen can raise the ratio of CD4
