[Analysis of relapse factors and risk assessment of adult acute lymphoblastic leukemia].

OBJECTIVE: To explore the risk factors of acute lymphoblastic leukemia (ALL) recurrence in adult patients and establish a prognosis index (PI) calculation model in order to improve the prevention strategy of ALL in adults. METHODS: 104 adult ALL patients from Blood Diseases Hospital & Chinese Academy of Medical Sciences between August 2008 and November 2011 were enrolled. COX proportional hazards regression stratified by Dummy variable was used to set up the prediction model; Kaplan-Meier method and Log-rank test were used to estimate and compare the survival. After calculated individual PI value, patients' expected survival should be estimated by groups. RESULTS: The overall median survival of adult ALL patients was 22.00 months (95% CI 17.00-27.00). COX regression analysis showed that chemotherapy group patients had a higher risk of recurrence than of ASCT group while setting treatment as the dummy variable (RR=2.052, 95%CI 0.877-4.799, P=0.007). Stratified Analysis showed that the risk factors of B-ALL recurrence in adult patients included HGB <100 g/L (RR=0.186, 95% CI 0.068-0.512, P=0.001), CNSL (RR=7.767,95% CI 2.951- 20.433, P=0.001), number of consolidation chemotherapy<3 (RR=0.445, 95% CI 0.211-0.940, P=0.034) and Ph chromosome positive (RR=2.771, 95% CI 1.353-5.674, P=0.005). Grouped by the PI value, the expected survival of each individual patient could be estimated as PI=0.58 base. CONCLUSION: HGB, CNSL, number of consolidation chemotherapy and Ph chromosome were independent risk factors of B-ALL recurrence in adult patients. PI value could predict the survival of adult ALL patients and provide reference for individual therapy and prognostic evaluation.

[Related factors on patients with depression related to Alzheimer's disease based on the improved cumulative logistic regression].

OBJECTIVE: To explore the determinants of Alzheimer's disease (AD) patients with depression. METHODS: The degree of depression on AD patients was assessed by the geriatric depression scale. Improved cumulative logistic regression (ICLR) was used to analyze the determinants of AD patients with depression. RESULTS: 196 AD patients were investigated. Among the 196 AD patients, there were 60 (30.6%) males and 136 (69.4%) females, at 58 - 89 years of age (72.3 ± 6.0). Physical activity, diabetes, MoCA, hearing, economic sources and alcohol were related to the degree of depression of AD patients (P < 0.10). The difference between "normal" and "mild depression" was smaller than difference between "mild depression" and "severe depression". CONCLUSION: AD patients with mild depression were the target population for prevention and they were influenced by several factors listed above.
