CD127 is the interleukin7 receptor ?(IL7R?),it regulates the specific respond of T lymphocytes to IL7.CD127 plays an indispensable role in the development of thymocytes into T lymphocytes,the survival and homeostatic proliferation of memory T cells.There are only two phases of the life period of T cells that do not express CD127:immature CD4+8+double positive(DP)thymocytes and activated T cells.Recently,it was found that CD127 play an important role as the specific marker of memory T cells and regulator T cells.The role and mechanism of CD127 in the life period of T cells were discussed herein.

OBJECTIVETo study the correlation between the expansion with different volume and the contents of the b-FGF and EGF in the expanded skin.

METHODSThe piglets were used in the experiment,which were divided into 7 groups including the sham, the blank control,the experimental groups with inflation of 1/2 volume, 3/4 volume, full volume, 150% volume and 200% volume. When expansion was complete, b-FGF was measured using enzyme coagulate method. EGF was measured by radioimmunoassay. The data were analyzed statistically.

RESULTSThe contents of b-FGF and EGF in the expanded skin was significantly higher than normal skin (P < 0.05). The difference in contents of b-FGF and EGF between the over-expanded skin and normal skin was more significant (P < 0.01).

CONCLUSIONExpansion can lead to the increase of b-FGF and EGF contents in the expanded skin.The biological effects may be relative to epidermal hyperplasia and angiogenesis of the expanded skin.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.

There has been increasing interest in the psycho-socio-relational and sexual disorders of infertility, as the risk of psychological burden among infertile men with sexual dysfunctions is significant. The purpose of this study was to develop and to validate a predictive model to estimate individual psychological burden among infertile men with sexual dysfunction and study the association between them. Comprehensive data were collected for infertile men (n = 480) who sought treatment for infertility in a reproductive medicine center between June 2012 and December 2013. Using independent predictors of psychological burden from the least absolute shrinkage and selection operator, univariable and multivariable analyses were developed into two models. Predictive accuracy was compared between the models. We explored the association between sexual dysfunction and psychological burden. A total of 480 patients were analyzed using 10-fold cross-validation. Independent predictors of psychological burden were incorporated into a model to measure anxiety (corrected-area under curve (AUC): 77.3%) and a model to measure depression (corrected-AUC: 70.2%). Anxiety and depression were both associated with erectile dysfunction (P < 0.05), with anxiety demonstrating the strongest association. Only anxiety was associated with premature ejaculation (P < 0.05). Premature ejaculation was not found to be associated with depression (P > 0.05). Predictive models for psychological burden among infertile men with sexual dysfunction are presented, and we found that there is an association between psychological burden and sexual dysfunction. According to the models, proper counseling and treatment of sexual dysfunction in infertile men may reduce the psychological burden, help attain natural pregnancy, and improve the quality of life.

To explore the expression potential of heterogeneous genes using the backbone of infectious bronchitis virus (IBV) Beaudette strain, the ectodomain region of the Spike gene (1,302 bp) of IBV H120 strain was amplified by RT-PCR and replaced into the corresponding location of the IBV Beaudette strain full-length cDNA. This recombinant was designated as BeauR-H120(S1). BeauR-H120(S1) was directly used as the DNA template for the transcription of viral genomic RNA in vitro. Then, the transcription product was transfected into Vero cells by electroporation. At 48 h post-transfection, the transfected Vero cells were harvested, and passaging continued. A syncytium was not observed until the recombinant virus had passed through four passages. The presence of rBeau-H120(S1) was verified by the detection of the replaced ectodomain region of the H120 Spike gene using RT-PCR. Western blot analysis of rBeau-H120 (S1)-infected Vero cell lysates demonstrated that the nucleocapsid (N) protein was expressed, which implied that rBeau-H120(S1) could propagate in Vero cells. The TCIDs0 and EIDs0 data demonstrated that the titer levels of rBeau-H120(S1) reached 10(590+/-0.22)TCID50/mL and 10(6.13+/-0.23)EID50/mL in Vero cells and 9-day-old SPF chicken embryos, respectively. Protection studies showed that the percentage of antibody-positive chickens, which were vaccinated with rBeau-H120(S1) at 7 days after hatching, rose to 90% at 21 days post-inoculation. Inoculation provided an 85% rate of immune protection against a challenge of the virulent IBV M41 strain (103EID50/chicken). This recombinant virus constructed using reverse genetic techniques could be further developed as a novel genetic engineering vaccine against infectious bronchitis.
