Objective To investigate the feasibility of hip replacement through a minimal incision via modified Hardinge approach.Methods Hip replacement was performed in 21 cases(22 hip joints) from July 2005 to March 2006.The operation was completed through a minimal incision via modified Hardinge approach,with the greater trochanter as the center.There were 12 cases of total hip replacement(13 hip joints) and 9 cases of bipolar femoral head replacement.A biological prosthesis was used in all the cases. Results The mean length of incision was 7.6 cm(range,6.0~9.0 cm),the mean operation time was 76 min(range,(45~)150 min),and the mean blood loss,370 ml(range,190~580 ml).No severe complications occurred.All the cases were followed for a mean of 38 weeks(range,22~53 weeks).Evaluation with the Harris hip score system showed excellent outcomes in 18 cases(19 hips) and good in 3 cases,with a rate of excellent or good results of 100%.Conclusions Minimal incision hip replacement through the modified Hardinge approach has advantages of minimal trauma,little blood loss,low complication rate,and quick recovery.

Molecular mechanisms underlying the effects of Fyn on cell morphology, pseudopodium movement, and cell migration were investigated. The Fyn gene was subcloned into pEGFP-N1 to produce pEGFP-N1-Fyn. Chinese hamster ovary (CHO) cells were transfected with pEGFP-N1-Fyn. The expression of Fyn mRNA and proteins was monitored by reverse transcription-PCR and Western blotting. Additionally, transfected cells were stained with 4',6-diamidino-2-phenylindole and a series of time-lapse images was taken. Sequences of the recombinant plasmids pMD18-T-Fyn and pEGFP-N1-Fyn were confirmed by sequence identification using National Center for Biotechnology Information in USA, and Fyn expression was detected by RT-PCR and Western blotting. The morphology of CHO cells transfected with the recombinant vector was significantly altered. Fyn expression induced filopodia and lamellipodia formation. Based on these results, we concluded that overexpression of mouse Fyn induces the formation of filopodia and lamellipodia in CHO cells, and promotes cell movement.

OBJECTIVE To assess the association of single nucleotide polymorphisms (SNPs) of susceptibility genes of type 2 diabetes mellitus (T2DM) with liability to gout among ethnic Han Chinese males from coastal region of Shandong province. METHODS Seven SNPs within the susceptibility genes of T2DM, including rs10773971(G/C) and rs4766398(G/C) of WNT5B gene, rs10225163(G/C) of JAZF1 gene, rs2069590(T/A) of BDKRB2 gene, rs5745709(G/A) of HGF gene, rs1991914(C/A) of OTOP1 gene and rs2236479(G/A) of COL18A1 gene, were typed with a custom-made Illumina GoldenGate Genotyping assay in 480 male patients with gout and 480 male controls. Potential association was assessed with the chi-square test. RESULTS No significant difference was detected for the 7 selected SNPs in terms of genotypic and allelic frequencies (P > 0.05). When age and body mass index (BMI) were adjusted, the 7 genetic variants still showed no significant association with gout. CONCLUSION The genotypes of the 7 selected SNPs are not associated with gout in ethnic Han Chinese male patients from the coastal region of Shandong province. However, the results need to be replicated in larger sets of patients collected from other regions and populations.
