Recent scientific achievements in cell and developmental biology have provided unprecedented opportunities for advances in biomedical research. The demonstration that fully differentiated cells can reverse their gene expression profile to that of pluripotent cells, and the successful derivation and culture of human embryonic stem cells (ESCs) have fuelled hopes for applications in regenerative medicine. Ethical issues concerning the use of cloned human embryos for the derivation of stem cells have stimulated the search for alternative methods for reversing differentiated cells into pluripotent cells. The present state of these reprogramming technologies will be reviewed and their relative success will be discussed.

Objective To investigate the intervention effects of NLP workshop on resilience of children from divorced family.Methods A pre/post test and subsequent follow-up design between experimental group and control group were performed.Thirty-one children from divorced family with low resilience were intervened by NLP workshop,while the other thirty-one children with low resilience were chosen as the control group.Results There was no significant difference between experimental group and control group before the intervention on resilience.But after the intervention,the two groups achieved statistical significant difference on resilience(experimental group (3:68±0.37),control group(2.99±0.18),t=9.60,P=0.00).Furthermore,the results of follow-up showed that the effect of NLP workshop still existed after six months (total average score of resilience before intervention (2.96±0.17),subsequent follow-ups (3.69±0.35),t=10.40,P=0.00).Conclusion NLP workshop can enhance the level of resilience of children from divorced family.Effect of NLP workshop not only has short-term effect,but also has some long-term effect.

ObjectiveTo compare children's resilience and peer relationship in divorced and complete family,and explore the moderating effect of psychological resilience between family structure and peer relationship.Methods208 children from divorced family and 465 children from complete family were surveyed.Results(1)There were significant differences in children's resilience(divorced family (3.58±0.73),complete family(3.83±0.59),t=-2.765,P=0.006) and peer relationship(divorced family (3.47±0.72),complete family(3.73±0.59),t=-2.069,P=0.042) between complete and divorced family.(2) Family structure had remarkable negative correlation with resilience and peer relationship(r1=-0.19,r2=-0.20),and resilience had positive correlation with peer relationship(r=0.43).(3)The moderating effect of resilience between family structure and peer relationship was significant(β=0.641,P<0.05).ConclusionParent divorce has negative influence on children's resilience and peer relationship.Furthermore,the relationship of family structure and peer relationship is mediated by resilience.The negative influence of parent divorce on peer relationship is not significant among children with high resilience,while it is significant on children with low resilience.

Objective To investigate the pressures from night shifts among nurses from pediatrics department and find the countermeasures.Methods A self-designed questionnaire was used to investigate the pressures from night shifts among 112 nurses from pediatrics department as well as the reasons.Results 110 of the nurses(98.2%) assumed that the pressures from night shifts was intensive.The main reasons for the pressures came out of heavy workload,shortage of staff and stuff and the unsettled balance between job and family.Conclusion Such measures as reasonable distributions of nurses,abound supply of stuff and reduced working links may be effective for the alleviation of the pressures on nurses at night shifts,motivated activeness in them and then the enhancement of nursing quality.

Objective:To produce monoclonal antibodies(McAb) against aspergillus fumigatus and to establish rapid assay for the measurement of aspergillus fumigatus antigen.Methods:Recombinant galactomannoprotein of aspergillus fumigatus(AFMP1) was used to immune BALB/c mice.Monoclonal antibodies against AFMP1 were produced from hybridoma.Results:Three hybridomas producing antibodies against AFMP1 were obtained.IgG isotypes of three McAb were IgG1,IgG2a and IgG2b.The affinity constants(K) were 1.2?10 10 ,4.56?10 9 and 1.81?10 10 mol/L.The antibodies were proved to be specific for aspergillus fumigatus by Western blot and recognized different epitopes on AFMP1 by the additivity assay.An sandwich enzyme-linked immunosorbent assay(ELISA) to detect AFMP1 was established to produce standard curve which showed linearity between 0.1～60.0 ng/ml with a sensitivity of 0.1 ng/ml.Conclusion:These results show three hybridomas producing high specificity and affinity monoclonal antibodies against AFMP1 and can provide for rapid assay for the measurement of aspergillus fumigatus antigen.

A neonatal girl with overextended knees admitted to NICU of our hospital was diagnosed as cri du chat (cat cry) syndrome.We collected 34 cases of cri du chat reported in journals since 2000,the clinical features of total 35 cases were retrospectively analyzed.Among 35 cases 12 were boys and 23 girls.The most common clinical manifestations were characteristic face features(100％),difficult feeding(100％) and typical sound of cry(94％).The main complains at hospital visit were typical cry,difficult feeding and cyanosis in the neonatal period,while in childhood period were recurrent respiratory infection,developmental retardation and other abnormalities.Most cases were diagnosed in the neonatal phase,while 85.3％ were in the first year.The diagnosis was based on karyotype analysis; chromosome 5 short arm deletion (5P-) was the most significant genetic variation and clinical features were associated with the position of deletion.
