Objective To explore the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with CCAAT/enhancer binding protein α (CEBPA) mutations.Methods 208 patients with de novo AML were retrospectively analyzed with regard to frequency of CEBPA mutations,clinical characteristics,therapeutic response and long-term outcome.Results CEBPA mutations were detected in 37 patients (17.8 %),with 29 cases of double mutations and 8 cases of single mutation.In 117 cases of patients with normal karyotype,28 cases (23.9 %) were detected with CEBPA mutations.As compared with no CEBPA mutation,the following characteristics were observed in patients with CEBPA double mutations.Presented with younger age at diagnosis,82.8 % (24/29) of the patients were M1 and M2.Presented with higher peripheral white blood cell count,higher hemoglob in and low platelet count.And increases of CD7,CD34 and HLA-DR expression.Compared with those without mutation,patients with biCEBPA mutations had better overall survival (OS) (2-years OS:100 % vs 75.1%,P =0.045).Conclusion BiCEBPA mutation is one of the favorable prognosis indicators.

ObjectiveTo explore the differences of cognitive function in patients with treatment-resistant depression and drug-naive first-episode major depressive disorder, and to examine the relationship between severity of clinical symptoms and cognitive function, so as to provide references for prognosis improvement. MethodsFrom November 2016 to December 2019, 119 patients with drug-naive first-episode major depressive disorder and 82 patients with treatment-resistant depression in a hospital in Guangzhou were enrolled, meantime, another 71 healthy individuals recruited from the community were set as healthy control group. Clinical symptoms were assessed using Hamilton Depression Scale-17 item (HAMD-17) and Hamilton Anxiety Scale (HAMA). Cognitive domains, including speed of processing, working memory, verbal learning and memory, and visual learning and memory were measured with the MATRICS Consensus Cognitive Battery (MCCB). Multiple covariance analysis was used to compare the differences in cognitive function among three groups. Thereafter, partial correlation analysis was performed within patient groups to explore the relationship of HAMD-17/HAMA score with the four dimensions of MCCB. ResultsThe speed of processing, visual learning and memory scores of treatment-resistant depression group and drug-naive first-episode depression group were lower than those of healthy control group, and the working memory score of the treatment-resistant depression group was lower than that of the healthy control group, with statistical significance (P<0.05 or 0.01). The speed of processing, visual learning and memory scores of treatment-resistant depression group were significantly lower than those of drug-naive first-episode depression group (P<0.05 or 0.01). Partial correlation analysis within patient groups found that HAMD-17/HAMA total score had no correlation with the four dimensions of MCCB (P>0.05). ConclusionCompared with drug-naive first-episode major depressive disorder patients and healthy controls, the impairments of speed of processing, visual learning and memory are more severe in patients with treatment-resistant depression. Moreover, the cognitive function impairment in patients with drug-naive first-episode major depressive disorder and treatment-resistant depression has no correlation with the severity of depressive and anxious symptoms.

BACKGROUNDRapid clearance of peripheral blood blasts (PBBs) predicts complete remission (CR) and survival in patients with acute myeloid leukemia (AML). We aimed to explore the correlation between induction therapy response, outcome, and the PBB percentage.
METHODSForty-six consecutive patients with de novo AML (excluding acute promyelocytic leukemia) were enrolled in this study. Flow cytometry was performed to identify cells with a leukemia-associated aberrant immunophenotype in the initial bone marrow aspirate and in peripheral blood on day 7 of induction therapy.
RESULTSThe PBB percentage on day 7 (D7PBBP) was significantly lower in patients who achieved CR (0.03% (0.0%, 0.45%)) than in those who did not (10.85% (1.13%, 19.38%); u = -3.92, P < 0.001). The CR rate was significantly higher among patients with a D7PBBP of <0.945% (84.62%, 22/26) than among those with a D7PBBP of = 0.945% (25.0%, 5/20; χ2 = 16.571, P < 0.001). D7PBBP was significantly correlated with overall survival (OS; r = -0.437, P = 0.003) and relapsefree survival (RFS; r = -0.388, P = 0.007). OS and RFS were significantly higher in patients with a D7PBBP of <0.43% than in those with a D7PBBP of ≥ 0.43% (P < 0.001 and P = 0.039, respectively). D7PBBP was also found to be an independent prognostic indicator in multivariate analysis for both OS (P = 0.036) and RFS (P = 0.035).
CONCLUSIOND7PBBP may be an important risk factor for the achievement of complete remission, for overall survival, and for relapse-free survival.
