Objective To look for a small molecular neurotrophin which could promote production and/or differentiation of neural stem cells (NSCs). Methods 1.Embryo hippocampal NSCs were cultured in vitro . 2. The neurospheres were identified by antibodies of bromodeoxyuridine (BrdU), glial fibrillary acid protein (GFAP), microtubule associated protein 2 (MAP2) and Galactocerebroside (GalC). 3. The cells were divided into four groups, which were control group, FBS treated group, trans-sequence of APP 5-mer peptide treated group, APP 5-mer peptide treated group. The morphology of NSCs was observed in above four groups. 4. Cell counts, detection of clone information rate and diameter of clone were done to study the effect of APP 5-mer peptide on production of NSCs. 5. In addition, we also detected the MTT metablism rates in all groups. Results 1. The NSCs formed neurospheres and grew in floating. They were BrdU-positive. GFAP-positive, MAP2-positive and GalC-positive cells appeared after FBS were added into the medium. 2. The morphology of NSCs was not changed in APP 5-mer peptide treated group and trans-sequence group compared with the control group. 3. The cell number increased in APP 5-mer peptide treated group as compared with the control group. There were no apparent differences between the control group and the trans-sequence treated group. 4. The clone formation rate and diameters of neurospheres increased in APP 5-mer peptide treated group. 5. The MTT metabolism rate increased in APP 5-mer peptide treated group. Conclusion APP 5-mer peptide could promote the production of embryo hippocamal NSCs in vitro. APP 5-mer peptide doesn't promote the differentiation of embryo hippocamal NSCs in vitro.

ObjectiveTo clarify the characteristics and clinical signiifcance of the NOTCH1 mutations in childhood T-cell acute lymphoblastic leukemia (T-ALL).MethodsAmplify and sequence the heterodimerization (HD) domain and the pro-line-glutamicacid-serine-threonine (PEST) domain of theNOTCH1 gene in 28 T-ALL children, in order to explore the frequency, position and type of the mutations as well as their reletions with prognosis.ResultsIn 28 children with T-ALL, 15 cases (51.57%) had been identiifed theNOTCH1 mutations, all of which were heterozygous mutations. The lymphoblast counts in peripher-al blood and bone marrow in theNOTCH1 mutant group at admission were signiifcantly higher than in the non-mutant group (P<0.05). The 1-year remission rate in the 28 children with T-ALL was 75% (21/28), including 80% (12/15) in mutant group in which 3 patients relapsed and all of them died (1-year mortality 20%) and 69.20% (9/13) in non-mutant group in which 4 patients relapsed but all survived (1-year mortality 0%).ConclusionsThe children with T-ALL had a high incidence of NOTCH1 mu-tations at various sites. In addition, the patients withNOTCH1 mutations had more severe disease at diagnosis, better short-term prognosis and poor outcome with salvage therapy after relapse.
