BACKGROUND:Now, domestic total knee arthroplasty surgeries mainly use medial parapatel ar approach, with the disadvantages of large trauma and slower recovery. The quadriceps sparing approach is more accorded with normal anatomy, which can keep the knee extension system intact. The clinical comparison between quadriceps sparing approach and medial parapatel ar approach is rare.
OBJECTIVE:To compare the early effect of total knee arthroplasty through quadriceps sparing approach and medial parapatel ar approach.
METHODS:From January 2009 to January 2010, 55 patients (70 knees) were randomly divided into quadriceps sparing approach group (n=26, 35 knees) and medial parapatel ar approach group (n=29, 35 knees). Patients in two groups received total knee arthroplasty through quadriceps sparing approach and medial parapatel ar
approach respectively. The incision length, operative time, postoperative drainage volume, additional amount of etoricoxib tablets, pain degree, straight leg raising time, start walking time, hospitalization time, range of motion of knee joint, Hospital for Special Surgery Knee Score, radiographic alignment of al components and complications were compared between two groups. Al the prostheses used in this study were the Sigma type prostheses
provided by the rotation platform of Johnson&Johnson Company.
RESULTS AND CONCLUSION:Al the patients were fol owed-up for 12-24 months without infections, deep vein thrombosis, neurovascular injury, prosthesis instability, prosthesis loosening or displacement. Position of al the
prostheses was normal in patients. The operative time in the quadriceps sparing approach group was longer than that in the medial parapatel ar approach group (P=0.00), while the incision length, postoperative drainage volume, additional
amount of etoricoxib tablets, visual analog scale, straight leg raising time, start walking time, hospitalization time, range of motion of knee joint at 3 days after replacement and Hospital for Special Surgery Knee Score in the quadriceps
sparing approach group were better than those in the medial parapatel ar approach group (P<0.05). There were no
significant differences in range of motion of knee joint at 3 days after replacement and Hospital for Special Surgery Knee Score between two groups. The early effect of total knee arthroplasty through quadriceps sparing approach is better than the medial parapatel ar approach, and there is no significant difference in prosthesis alignment between two methods.

Objective To investigate the effects of all trans-retinoic acid (ATRA) on the expressions of iron metabolism-related genes and their products in K562 cells and the possible relationship. Methods (1) The characteristics of K562 leukemic cell differentiation induced by ATRA was evaluated by Benzidine, Wright's, NSE and NBT staining.(2) The expression levels of cellular surface antigens (CD71 and CD 13) in K562 cells cultured with ATRA were measured by flow cytometry. (3) IRP/IRE binding activity was assessed by RNA/protein band-shift assay.(4) Ferritin was determined by radioimmunoassay.(5) The mRNA expression levels of H-Fn, TfR and IRP2 in K562 cells cultured with different concentrations of ATRA were delineated by RT-PCR method, confirmed by sequencing of RT-PCR products. Results K562 cells could be induced to differentiate into neutrophils by ATRA, confirmed by cytochemical staining. The expression of CD71 decreased while CD13 increased. The mRNA expression levels of TfR and IRP2 were decreased while mRNA expression level of H-Fn was increased in K562 cells cultured with ATRA, compared to that in control cells. Concomitantly,IRP binding activity was significantly decreased but the level of ferritin was significantly increased in K562 cells cultured with ATRA. Conclusions During the course of K562 cells induction and differentiation to myelocytes by ATRA, the expression level of iron metabolism-related genes and products were changed but the upstream-regulation mechanism still remains unclear.
