Objective Previous study found that ifbroblast growth factor-2(FGF2) expression was at a low level in bone marrow of children with aplastic anemia. In this study, we established a bone marrow failure animal model to investigate whether FGF2 is involved in bone marrow failure. Methods BALB/c mice were irradiated by 5.0 Gy ray, and then infused with 1×106 lymphocytes from allogeneic mice lymph node. Peripheral blood cells and bone marrow mononuclear cells counting and bone marrow pathology were done. FGF2 protein in bone marrow mononuclear cells was measured by ELISA. Results Compared with the control group, the counting of hemoglobin, white blood cell, platelet and bone marrow mononuclear cell in aplastic anemia mouse model were signiifcantly deceased (P<0.05). Moreover, FGF2 expression in aplastic anemia mouse model were signiifcantly reduced (P<0.05). Conclusions 5.0 Gy ray irradiation and then 1×106 lymphocyte infusion in mice can induce bone marrow failure similar to the features of aplastic anemia. The low expression of FGF2 in bone marrow of aplastic anemia patients may play an important role in the pathogenesis of aplastic anemia.

Objective To study the relationship between genotypes and phenotypes,geographical distribution,and the sites of infection of Trichophyton rubrum(T.rubrum).Methods The genotypes were determined by Southern blotting with a probe amplified from the small-subunit rDNA and adjacent internal transcribed spacer(ITS)regions.The phenotypes of T.rubrum were determined by conventional method.Results Twenty genotypes(DNA type A to T)and5phenotypes(villous,furrowed,granular,powdery,and woolly)were recognized among49strains of T.rubrum.Genotype A prevailed in all phenotypes except granu-lar type.Type B represented the most common genotype among the strains of villous type and furrowed type.Type A took the first place in powdery type and woolly type.All of the type A strains were from Dalian.Seven of9type B strains were from Nanjing.Six type C strains were all from Nanjing.The majority strains of21strains isolated from tinea unguium were type C,most of the16strains isolated from tinea cruris and tinea corporis were type A,8strains from tinea pedis were type B,and4strains from tinea capitis were type C.Conclusion There are certain possible relationships between genotypes and phenotypes,geographical distri-bution and sites of infection of T.rubrum.

Objective: We studied the differences in intelligence,self-concept and behavior problem between girls with true precocious puberty and the normal girls.Methods: 35 girls with true precocious puberty aged 8 to 10 years was put into the research group;another 35 girls was put into the normal group(n=35).Both the research group and normal group completed the Piers-Harris Children's Self-concept Scale(PHCSS) and Raven's Standard Progressive Matrices in order to evaluate their levels of self-concept and intelligence respectively.Their parents completed a Child Behavior Check-list(CBCL) and a questionnaire on background status.Results: ①Children in the research group had significantly higher intellectual level than those in the control group.②The PHCSS yielded significantly lower scores of total self-concept,behavior and somatic appearance in the research group than those of the control group.③Higher scores of internal behavior problems,external behavior problems,depression,poor social communication,somatic complaints,delinquent behavior and aggressive behavior at CBCL showed in the research group than those of the control group.Conclusion: ①The level of intelligence of the children in research group was higher than that of children in the control group.②Girls with true precocious puberty showed more behavior problems and lower level of self-concept than those in the control group.

The ubiquitin-like modifier bISG15 is an antiviral protein found in fetal bovine lung (FBL) cells.Bovine Herpesvirus 1(BHV-1),which is a viral pathogen of cattle,can infect FBL cells and induce cytopathic effects.Real-time PCR assays showed that BHV- 1 's infection could repress the basal or inducible transcription of bISG15 in FBL cells.It demonstrates that this repression effect depends on BHV-1 viral infection and new protein synthesis.Our previous work showed that bIRF-3 was the key factor in the stimulation of bISG 15 in FBL cells,so the effect of BHV-1 viral protein on bIRF-3 activating the promoter of bISG15 was confirmed.The luciferase assay showed the BHV-1 viral protein bICP0 inhibited the activation of bISG15 promoter stimulated by bIRF-3.Taken together,our work suggested that BHV-I had some molecular mechanism to resist the cellular bISG15'santiviral functions.

Objective To analyze the percentage and functional changes of natural killer T (NKT) cells in peripheral blood and bone marrow of severe aplastic anemia (SAA) children before immunosuppressive therapy (IST) comparing to that of healthy children.Methods Ten children with severe aplastic anemia were included in the study and ten healthy children at the same age were selected as the control group. By lfow cytometry, the percentage of CD3+CD1d tetramer+ NKT cell in peripheral blood and bone marrow were detected from March 2014 to December 2014 in our hospital. Immune magnetic bead separation was used to isolate and purify iNKT cells .The puriifed iNKT cells were cultured in the OCH(50 ng/ml,100 ng/ml or 200 ng/ml)+rhIL-2+rhG-CSF culture systems. The ampliifcation of iNKT cells after cultured in different systems were calculated. Elispot method was used to analyze the spotting form cells (SFCs) of IFN-γ or IL-4 expressed by activated iNKT cells.Results The percentage of CD3+CD1d tetramer+ NKT cells in peripheral blood of SAA group(0.72±0.03)% was signiifcantly lower than that of the control group(0.92±0.02)%(P=0.000). The percentage of CD3+CD1d tetramer+ NKT cells in bone marrow of SAA group(0.82±0.02)% was signiifcantly lower than that of the control group(1.05±0.05)%(P=0.000).In vitro iNKT cell ampliif-cation ability of bone marrow in SAA group was signiifcantly lower than the control group, and in medium concentration(50±6) and high concentration OCH group(52±6), the ampliifcation ability was higher than that in low concentration OCH group(30±5) (P<0.05). The secretion of IFN-γ in the iNKT cells of SAA bone marrow was signiifcantly lower in medium concentration(33±3) and high concentration(35±3)OCH group than that of the low concentration(50±3)OCH group(P<0.01). The secretion of IL-4 in the iNKT cells of SAA bone marrow was signiifcantly higher in medium concentration(50±3)and high concentration(75±3) OCH group than that of the low concentration(33±3) OCH group(P<0.01).Conclusions The quantity and function of NKT cells from children with SAA are lower than that of the healthy children.In vitro, they had better ampliifcation ability and could improve IL-4/IFN-γ imbalance in medium concentration and high concentration OCH group than in low concentration OCH group.

Objective To establish an animal model of dermatophytosis and to evaluate antifungal efficacy on dermatophytosis with this model. Methods Animal models of dermatophytosis were established by inoculating dermatophyte suspension onto abraded skin on the back of guinea pigs. Thirty- eight healthy guinea pigs were randomly and equally divided into 2 groups, namely, Trichophyton mentagrophytes group (infected with T. mentagrophytes), and Microsporum canis group (infected with M. canis), and each group was classified into three subgroups, i.e., itraconazole group treated with oral itraconazole of 4 mg per kilogram body weight per day from day 0 to day 14 after infection, terbinafine group treated with oral terbinafine of 5 mg per kilogram body weight per day from day 0 to day 14 after infection, and untreated group receiving no therapy. The therapeutic effect was evaluated according to skin lesion score and fungal examination results on day 8, 11 and 14 after infection. Results Obvious lesions were observed and fungal examination was positive in untreated, infected pigs on day 8 after infection. In T. mentagrophytes-infecyted pigs, the skin lesion score on day 8, 11, 14 was 9, 1 and 0 in itraconazole group, 8, 5, and 1 in terbinafine group, 48, 52, 40 in untreated group, respectively, and there was significant difference between treated and untreated groups on the three time points (all P<0.01); the mycological cure rates on the above time points were 66.7%, 83.3%, 83.3%, in itraconazole-treated pigs, 83.3%, 83.3%, 83.3%, in terbinafine-treated pigs, 0, 0, 0 in untreated pigs, respectively, with no significant difference between itraconazole and terbinafine group (all P>0.05) but statistical difference between untreated and treated groups (all P<0.01) on all time points. Meanwhile, in M. canis-infected pigs, the skin lesion score on day 8, 11, 14 reached 3, 0, 0 in itraconazole group, 9, 2, 0 in terbinafine group, 46, 47, 39 in untreated group, respectively, and mycological cure rates 83.3%, 83.3%, 83.3% in itraconazole group, 83.3%, 83.3%, 83.3% in terbinafine group, 0, 0, 0 in untreated group, respectively; significant difference was noticed in the two parameters between the treated and untreated groups (all P<0.01) but not between the two treated groups (all P>0.05). Conclusion Itraconazol and terbinafine exhibit similar excellent antifungal activity in routine model of T. mentagrophytes-and M. canis-dermatophytosis.
