Objective It has been shown that ketamine and magnesium used in combination provide more effective analgesia than either drug alone. The purpose of this study was to investigate the effects and interaction of the two drugs on recombinantly expressed NMDA receptors. Methods Xenopus oocytes expressing NR1/NR2A or NR1/NR2B glutamate receptors were stimulated with glutamate/glycine and studied at a holding potential of -70mV using two electrode voltage clamp. The effects of magnesium and s ( + )-ketamine alone or in combination on NMDA signaling were determined. Results Magnesium and s( + )-ketamine alone inhibited NMDA receptors non-competitively. IC50s of magnesium were (4.2 ± 1.2)×10-4mol/L and (6.3 ± 2.4) × 10-4 mol/L on NR1/NR2A and NR1/NR2B, while IC50s of s( + )-ketamine on NR1/NR2A and NR1/NR2B were (4.1 ± 2.5) × 10-6 mol/L and (3.0 ± 0.3 ) × 10-6 mol/Lrespectively. Magnesium and s( + )-ketamine used in combination decreased IC50s more than 90% at both receptors. Isobolographic analysis demonstrated superadditive interactions. Conclusions s( + )-ketarnine and magnesium inhibit responses of recombinantly expressed NMDA recptors non-competitively, and the combinations of the two drugs produces a synergistic effect.

Objective To introduce a new CT classification system we designed for Hoffa fractures and compare the interrater reliability between the CT and X-ray classification systems.Methods A total of 20 isolated Hoffa fractures from January 2008 to December 2011 were randomly selected for the present analysis of their imaging data (anteroposterior and lateral X-ray films of the knee joint and three-dimensional CT reconstruction of the femoral condyle).At the same time,a total of 20 independent observers (clinicians with junior,intermediate and senior professional qualifications) were selected for classification of the Hoffa fractures in the same manner respectively according to the Letenneur's X-ray system and our self-designed CT system.We used Kappa statistics to evaluate the interrater reliability among the clinicians between the 2 classification systems for Hoffa fractures.Results According to the CT classification of the 20 Hoffa fractures by the 20 clinicians,type Ⅰ,Ⅱ and Ⅲ fractures accounted for 66.0％,30.5％ and 3.5％ respectively.In type Ⅰ fractures,type Ⅰb involving zone b accounted for the most (50.0％),next by type Ⅰc(31.0％) and type Ⅰa (19.0％).In type Ⅱ comminuted fractures,fracture fragments were mostly seen in zone b.The overall incidence of fractures involving zone b by CT classification was 67％.According to the X-ray classification,type Ⅰ,Ⅱ,Ⅲ and Ⅳ fractures accounted for 31.4％,14.3％,28.0％ and 26.3％,respectively.The interrater reliability for CT classification agreement (Kappa =0.681) among clinicians was higher than that for X-ray agreement (Kappa =0.261).Conclusion For Hoffa fractures,communicated ones in particular,our CT classification system may be better than the X-ray classification system.

Objective To explore the anti-sliding plating for Hoffa fractures by comparing the me-chanical properties of anti-sliding plates and cancellous bone screws. Methods Twenty cases of the same type of Hoffa fracture in the model femur were randomly divided into 4 even groups. Group A used 2 antegrade cancellous bone screws; Group B used 2 retrograde cancellous bone screws forwards; Group C used anti-sliding plate and locking screw fixation; Group D used anti-sliding plate and cancellous bone screw fixation. All the samples were subjected to the cycle fatigue and the maximum failure load tests. Results The fatigue test revealed no significant difference in the mean maximum displacements at the 10, 100, 1000, 10 000 cycles between the 4 groups. In the maximum failure load test, there were significant differences between Group A [(1224±72) N] and Groups C and D [(2183±227) N and (2124±235) N], as well as between Groups B [(1405±235) N] and Groups C and D; there was no significant difference between Group A and Group B, neither between Group C and Group D, Conclusions In the initial period after secure fixation for Hoffa fractures, anti-sliding plates and cancellous bone screws can all provide satisfactory mechanical stability and strength. But anti-sliding plating is recommended for cases of long healing expected, patients with great body mass index, and patients with poor compliance.
