Objective To test the reliability and validity of the brief International Classification of Functioning, Disability and Health (ICF) core sets for Chinese stroke patients using Rasch model analysis. Methods The body functions of 38 Chinese stroke patients were measured using the brief ICF core sets. The qualifiers of the 20items were measured by two raters and analyzed using FACETS statistical software. The intra-rater reliability and validity were tested by using the separation index and separation reliability and fit analysis. Results The brief ICF core sets had good internal consistency and reliability (person separation index = 6.02, person separation reliability = 0.94 ) with these Chinese patients. The raters showed significantly different strictness in rating, but their ratings had good internal self-consistency. The construct validity was good for the body functions of the ICF component ( separation index = 10.50, separation reliability = 0.80) , but misfitting and overfitting were found in items b117, b152and b755. Conclusion The body function of the brief ICF core sets has good reliability and validity for Chinese stroke patients. A many-facet Rasch measurement model can provide comprehensive information and has good application prospects for testing the reliability and validity of ICF core sets.

Objective To establish an expression system of TCRγ9/δ2-Fc protein by baculovirus vector ex-pression system and identify biological function of expressed TCRγ9/δ2-Fc protein. Methods γ9Fc and 82 (OT3) Fc gene fragments were amplified by overlap PCR and inserted into expression vector pBACp10ph. The recombinant plasmid pBACp10ph-γ9/δ2(OT3)-Fc and the baculovirus DNA were co-transfected into st9 cells. The expression position of TCRγ9/δ2 (OT3)-Fc was identified by Western blot and the expression efficiency of γ9Fc and δ2 (OT3) Fc was tested by flow cytometry (FCM). Furthermore, the binding activity of TCRγ9/δ2 (OT3)-Fc protein with SKOV3 ceils and MNS protein was evaluated with laser scanning confocal microslopy and surface plasmon resonance (SPR). Results The recombinant vector pBACp10ph-γ9/δ2(OT3)-Fc was constructed and TCRγ9/δ2(OT3)-Fc protein was expressed in sf9 ceils. However, the expression efficiency of γ9Fc and 82 (0T3) Fc was quite differ-ent. It was proved that purified TCRγ9/δ2 (OT3)-Fc protein can bind with SKOV3 cell and MNS protein. Conclu-sion TCRγ9/δ2-Fc protein is successfully expressed in baculovirus vector expression system and TCRγ9/δ2-Fc protein can simulate the binding activity of TCR in vitro.
