BACKGROUND:Many studies have demonstrated that restoration of femoral offset in revision total hip arthroplasty would contribute to the recovery of joint function.OBJECTIVE:To investigate the importance of restoration of femoral offset in revision total hip arthreplasty on the recovery of joint function.METHODS:An observational study was performed at the Department of Orthopedics,Third Affiliated Hospital of Guangzhou Medical University between February 2004 and May 2007.A total of 15 patients with the revision total hip arthroplasty,including 12 males and 3 females,aging 62 75 years,averaging 67 years old,were recruited into this study.Harris evaluation system was used to evaluate joint function.The femoral neck anteversion and the femoral offset were measured by the method of Sakai.The vertical distance from the teardrop line to the most prominent point of the lesser trochanter was measured from each radiograph.References were combined to investigate the effect of restoration of femoral offset in revision total hip arthroplasty on joint function.RESULTS AND CONCLUSION:All the 15 patients were recruited into this study.The duration of follow-up ranged from 24 months to 5 years.We measured the femoral offset on pre- and post-operative radiographs,and the results indicated that the femoral offset of 4 patients were above 4 mm.The femoral offset of 11 patients was restored.The femoral offset were 22-48 (32.21±0.64) mm pre- and 22-57 (36.13±0.82) mm post-operative radiographs,respectively.The mean difference in femoral offset post-operatively was significant (t=0.424,P=0.01 ).Harris scores were good in 4 cases,passable in 2 cases,and poor in 9 cases pre-operatively,and the scores were excellent in 8 cases,good in 4 cases,passable in 2 cases,and poor in 1 case post-operatively.The score of Harris evaluation system in the patient of restoration group and failed restoration group were 88.72±5.3 (80%) and 72.32±6.5 (27%) post-operative at 1 month respectively.The mean difference of the score was significant (χ~2=1.245,P<0.05).The 3 patients had complication,one was the dislocation of hip,and two had the pain of hip.All the patients with complication were in failed restoration of femoral offset,which was above 4 mm.The restoration of femoral offset contributes to the recovery of joint function and reduce complication occurrence after total hip arthroplasty revision.

Objective To explore the roles of macrophage inflammatory protein-1?(MIP-1?)in hypoxic-ischemic encephalopathy(HIE)of newborn infarnts.Methods Serum samples were obtained in 24,72 h and 7 d after birth respectively from 34 newborn infants with HIE,and 20 newborn infants without HIE as control group.Enzyme-linked immunosorbent assay(ELISA)method was used to determine the serum concentrations of MIP-1?.Results Levels of MIP-1? in newborn infants with HIE [(12.47?2.51)ng/L]were significantly higher than that of newborn infants without HIE [(8.63?2.63)ng/L](P0.05).Conclusions MIP-1? are involved in HIE of neonates,and the more severe damage,the higher levels in serum,which suggests that,as an inflammatory mediator,the MIP-1? may play an important role in involvement of brain hypoxic-ischemic damage.

Objective To explore a method for isolation and culture of human epidermal stem cells. Methods Epidermis was obtained by digesting human foreskin with Dispase Ⅱ and Trypsin-EDTA.After suspension on the epidermal stem cell medium (ESCM), these single epidermis cells were inoculated onto human collagen Ⅳ-coated flasks and cultured at 37 ℃ in a humidified atmosphere containing 5% CO_2 for 10 min. The nonadherent cells were rinsed off 10 min after inoculation, and the adherent cells continued to be cultured after enriching and abstraction by type Ⅳ collagen. The cell growth was observed through inverted microscope, and the cell cloning efficiency and time of clone sustain were also detected. Immunocytochemistry was used to observe the expression of ?_1-integrin and keratin 19(K19). Keratinocytes were served as controls. Results It was revealed by histological observation that colonies were formed 24 hours after inoculation. The isolated and cultured cell cloning efficiency was higher and the time of clone sustain was longer than that of the control group. Positive expression of ?_1-integrin and K19 of cultured cells was detected by immunocytochemistry. Conclusion Adult epidermal stem cells could be successfully isolated and cultured by adhension with type Ⅳ collagen and culture with ESCM.

OBJECTIVETo investigate the effect of rapamycin on the proliferation of rat valvular interstitial cells in primary culture.

METHODSThe interstitial cells isolated from rat aortic valves were cultured and treated with rapamycin, and the cell growth and cell cycle changes were analyzed using MTT assay and flow cytometry, respectively. RT-PCR was used to detect mRNA expression levels of S6 and P70S6K in cells, and the protein expressions level of S6, P70S6K, P-S6, and P-P70S6K were detected using Western blotting.

RESULTSRat aortic valvular interstitial cells was isolated successfully. The rapamycin-treated cells showed a suppressed proliferative activity (P<0.05), but the cell cycle distribution remained unaffected. Rapamycin treatment resulted in significantly decreased S6 and P70S6K protein phosphorylation level in the cells (P<0.05).

CONCLUSIONThe mechanism by which rapamycin inhibits the proliferation of valvular interstitial cells probably involves suppression of mTOR to lower S6 and P70S6K phosphorylation level but not direct regulation of the cell cycle.
