0,most symptoms of ADR were reported for the first time with the homogeneous literature ratio being 0.The predominant outcome of severe ADR were hospitalization or delayed hospitalization course,followed by increased risk of death or patients' permanent or distinct disabling.CONCLUSION:New and severe ADR should be given close attention in the clinic to guard against severe ADR.

Objective To investigate the relationship between promoter hypermethylation of secreted frizzled-related protein (SFRP) gene and acute leukemia (AL). Methods We examined the promoter methylation starus of SFRP1, 2, 4 and 5 in primary or relapsed AL patients, cell lines ( HL60,NB4, Molt-4 and Jurkat) and peripheral blood mononuclear cells from healthy people with methylationspecific PCR (MSP). Results None of the normal mononuclear cells showed methylation of any SFRP genes. The frequencies of aberrant methylation among the samples were 33.9% (20/59) for SFRP1,23.7%(14/59) for SFRP2, 6. 8% (4/59) for SFRP4 and 10. 2% (6/59) for SFRP5 in acute myelocytic leukemia (AML), and 39.3% (11/28) for SFRP1, 28.6% (8/28) for SFRP2, 25.0% (7/28) for SFRP4 and 32. 1% (9/28) for SFRP5 in acute lymphoblastic leukemia (ALL). Hypermethylation of SFRP1, 2, 5genes were present in the 4 AL cell lines. SFRP4 was methylated in NB4, Molt-4 and Jurkat cell lines.However, methylation and unmethylation of SFRP4 were both detected in HL60. Conclusions Hypermethylation of SFRP genes is a common event in the evolution of AL. Methylation of SFRP genes might serve as potential independent biomarkers for early detection of AL.

Objective To explore the relationship between serum 25 (OH)D level and cognitive function in patients with Alzheimer's disease (AD).Methods Totally 113 AD impatients were enrolled in this study.Their serum 25 (OH) D2,25 (OH) D3,and total 25 (OH) D levels were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS).Patients were divided into Vitamin D severe deficiency group [25 (OH)D level≤25 nmol/L],deficiency group [25 (OH)D levels:25-50 nmol/L],insufficiency group [25 (OH) D level:50-75 nmol/L],and sufficiency group [25 (OH) D level ≥ 75 nmol/L] according to the criteria proposed by US Institute of Medicine.The cognitive function was assessed by MMSE score.The association between serum 25 (OH) D level and cognitive function was systematically analyzed.Results The serum levels of 25 (OH) D,25 (OH) D2,and 25 (OH) D3 were (27.08 ± 15.33) nmol/L,(1.23 ± 0.93) nmol/L and (24.50 ± 13.04) nmol/L in AD patients.The proportions of severe deficiency,deficiency,insufficiency,and sufficiency were 60.18％ (68/113),30.97％ (35/113),7.97％ (9/113),and 0.88％ (1/113),respectively,among these AD patients.A positive correlation was found between serum 25 (OH) D concentration and MMSE score in AD patients.Conclusions Impatients with AD often have severe vitamin D deficiency and need vitamin D supplementation.Serum 25 (OH) D concentration is associated with cognitive function,and therefore vitamin D supplementation may improve cognitive function.

Objective:To explore the clinical characteristics of chronic kidney disease (CKD) at the stage 3-5D in children with renal anemia, and provide reference data for standardized diagnosis and treatment.Methods:A single-center retrospective study was conducted to collect clinical data in children with CKD at Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2018. The patients were divided into CKD stage 3 group, stage 4 group and stage 5 group according to estimated glomerular filtration rate. The indexes of anemia among the groups were compared. Data on anemia indicators, treatment, and anemia improvement in maintenance dialysis children at stage 5D were analyzed.Results:A total of 171 children with CKD were included in the study. The hemoglobin levels in CKD stage 3 group, stage 4 group and stage 5 group were (126.4±20.5) g/L, (90.8±26.0) g/L and (78.7±18.4) g/L, respectively, and there was a statistical difference among the groups ( χ2=61.982, P<0.001; trend test F=71.061, P<0.001). The incidences of anemia in children with CKD stage 3, stage 4 and stage 5 were 27.3% (9/33), 83.3% (25/30) and 95.4% (105/108), respectively. Mild, moderate and severe anemia in children with CKD stage 3 accounted for 15.2%(5/33), 12.1% (4/33) and 0(0), respectively. Mild, moderate and severe anemia in children with CKD stage 4 accounted for 26.7% (8/30), 50.0% (15/30) and 6.7% (2/30), respectively. Mild, moderate and severe anemia in children with CKD stage 5 accounted for 21.3%(23/108), 60.2%(65/108) and 15.8%(17/108), respectively. Anemia type was mostly normocytic anemia. The hemoglobin of 30 children with CKD stage 5D at the initial stage of dialysis was (79.3±16.3) g/L. Twenty-three children with CKD stage 5D received erythropoietin combined with oral iron or intravenous iron therapy. The hemoglobin compliance rates in children with maintenance dialysis in initial phase, 1 month, 2 months and 3 months were 6.7% (2/30), 16.7%(5/30), 63.3%(19/30) and 90.0%(27/30), respectively. The correction time for anemia was (2.5±1.0) months. Twelve children with CKD stage 5D received iron sucrose infusion, and no adverse reaction occurred. Conclusions:Renal anemia has a high incidence in children with CKD. Early and standardized treatment is of great significance to improve outcome of renal anemia. Venous iron infusion is a safe and effective treatment method for children with maintenance dialysis.
