Objective To investigate the clinical characteristics of elderly patients with multiple myeloma and their prognostic factors.Methods 100 multiple myeloma patients with age≥ 60 years and 100 multiple myeloma patients with age <60 years who admitted in our hospital from December 2007 to December 2015 were collected as research subjects.100 patients with age ≥60 years were divided into elderly multiple myeloma group,100 cases with aged <60 years were divided into non -elderly multiple myeloma group.The clinical data and laboratory results of two groups were compared,the prognosis factors in elderly patients with multiple myeloma were analyzed.Results The incidence rate of ISS stage Ⅰ -Ⅱ in elderly multiple myeloma group (45.0%)was lower than non -elderly multiple myeloma group (60.0%),the incidence rate of stage Ⅲ was higher than non -elderly multiple myeloma group (χ2 =4.511,P <0.05).The infection incidence of elderly multiple myeloma group(30.0%)was higher than non -elderly multiple myeloma group(15.0%)(χ2 =10.452,P <0.05 ).The hemoglobin,serum albumin contents of elderly multiple myeloma group [(83.7 ±19.8)g/L,(27.89 ±6.87)g/L]were less than non -elderly multiple myeloma group[(92.1 ±22.5)g/L,(33.15 ±7.69)g/L](t =4.297,4.426,all P <0.05).The calcium content,the propor-tion of bone marrow plasma cells,serum creatinine and blood β-microspheres protein levels of elderly multiple mye-loma group [(2.51 ±0.41)mmol/L,(39.43 ±18.64)%,(182.24 ±125.47)μmol/L,(9.02 ±6.24)mg/L]were higher than non -elderly multiple myeloma group [(2.36 ±0.48)mmol/L,(37.45 ±19.86)%,(143.25 ± 116.43)μmol/L,(5.87 ±3.41)mg/L](t =5.945,4.196,4.375,4.264,all P <0.05).The median survival time of elderly multiple myeloma patients were significantly correlated with the patients'age,the proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin,and ISS staging (χ2 =4.125,3.254,8.542,5.748,9.244,all P <0.05).Conclusion The condition of elderly myeloma patients is more serious,age,proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin and ISS stage affect myeloma patients prognosis.

BACKGROUND: Educative instruction is good for the improvement of learning and behavior disorder in children with learning disorder. If this educative instruction were individualized, i. e. different education is provided for different individual, it would receive even better effects.OBJECTIVE: To explore the method and effect of educative instruction for children with learning disorder to accumulate experiences for the development of their learning potentials.DESIGN: A paired(pairing the subjects with similar age and learning disorder) case analysis based on the suffers .SETTING: A medical college of some university.PARTICIPANTS: Eight children with learning disorder were selected from Zhenjiang City Dongwu Kindergarten or Zhenjiang City Dagang Central Primary School. These 8 cases suffered from 4 types of disorders including clumsiness, seclusive personality, language disorder, and poor learning ability. Eight cases were randomly divided into education group and control group.METHODS: Cases of control group received normal educations without specific interventions. Cases of education group received individual customized educative instructions. The educative effects were observed after 3 months.MAIN OUTCOME MEASURES: The improvement of clumsiness, seclusive personality, language disorder or poor learning ability in children with learning disorder.RESULTS: Cases of education group had better psychological and behavior improvements than that of control group after individual educative instruction.CONCLUSION: Individual educative instruction for children with learning disorder is an effective approach for the development of their learning potentials.
