Objective To construct the recombinant adenovirus encoding mouse wild type FGFR3 cDNA. Methods Mouse FGFR3 cDNA obtained from MoFR3/SV was subcloned into plasmid pBluescript KS and further cloned into plasmid pAdTrack-CMV. The plasmid (pAdTR3) was transferred into BJ5183 cells which contained the adenovirus plasmid (pAdeasy-1) to produce recombinant adenovirus vector encoding FGFR3 cDNA (pAdE-FGFR3). The recombinant adenovirus vector was identified and transfected into the adenoviral packaging cell HEK293 by lipofectamine 2000 to get recombinant adenovirus particles. The adenovirus was confirmed by polymerase chain reactin (PCR) and its titer was determined. Then the recombinant vector was transfected into HT29 cells. The expression of FGFR3 mRNA and protein in HT29 cells was assayed by RT-PCR and Western blotting. Results The recombinant adenovirus vector encoding FGFR3 cDNA was correctly constructed and confirmed by restriction endonuclease analysis and DNA sequencing analysis. The transfected HEK 293 cells were lysed by freeze-thawing to obtain the recombinant adenovirus in the lysate. Further, PCR product of the lysate confirmed the presence of recombinant adenovirus. The viral titer was 3?109pfu/ml. RT-PCR and Western blotting showed that pAdE-FGFR3 transfected HT29 group expressed FGFR3 higher than that of GFP controlled group. Conclusion Infective recombinant adenovirus encoding FGFR3 cDNA was successfully obtained by plasmid homogenous recombination in bacteria, and highly expressed in HT29 cells after transfection, which paves a way for studying the effect of FGFR3 in bone fracture healing.

BACKGROUND:Primary dislocation after total hip arthroplasty is a major complication, besides prosthesis loosening. It is controversial whether joint capsule and external rotators should be repaired during total hip arthroplasty through posterolateral approach.
OBJECTIVE:To explore the clinical significance of joint capsule and external rotator repair on preventing hip dislocation after primary total hip arthroplasty through posterolateral approach.
METHODClinical data of patients with primary or secondary hip osteoarthritis after primary total hip arthroplasty through posterolateral approach were retrospectively analyzed. They were assigned to two groups according to different strategies of soft tissue repair. Control group did not receive posterior soft tissue repair. Combined repair group received the repair of joint capsule and short external rotators. Al patients were fol owed up for more than 1 year. Early dislocation was defined as the dislocation occurred within 1 year after operation. The effects of different repair methods on early dislocation rate were compared.
RESULTS AND CONCLUSION:There were 362 patients. Total y 390 case-times of primary total hip arthroplasty were included. Early dislocation occurred in 7 cases, of which 6 case-times in the control group (2.2%, 6/268), and 1 case-time in the repair group (0.8%, 1/122). There were significant differences in the incidence rate of early dislocation between the repair group and control group (P=0.012). These findings confirmed that the combined repair of posterior joint capsule and short external rotators could decrease the rate of early dislocation after primary total hip arthroplasty through posterolateral approach.
