ObjectiveTo study the optimized security strategy for informing cancer patients with the disease,and let patients be fully informed and even more actively cooperate with doctors while they are under treatment.MethodsGrouped with adversity quotient (AQ) score,these cancer patients were in comparison with those who had been informed by other ways without support strategy,and different groups of patients were estimated in different strategies in accordance with self-rating anxiety scale (SAS) and self-rating depression scale (SDS).Results With certain strategies,high and low AQ score groups' SAS and SDS scores stably restored in 1 day to 1 week,and the differences had statistical significance(P ＜ 0.01 ).The patients were well-informed without any difficulty and actively cooperated with treatment.No related factors led to self-mutilation,suicide and other serious incidents.While the SAS and SDS scores of the control group who were not informed by the strategy were not satisfactorily recovered,and the patients could not actively cooperate with the doctors.Especially being notified after 1 d to 1 week,the SAS and SDS scores had no significant improvement,and the differences had no statistical significance compared with themselves ( P ＞ 0.05 ).It is difficult to avoid the occurrence of serious incidents.Conclusion Based on AQ score,it is safe and effective to inform cancer patients of their disease condition by individual strategies.It not only respects patients rights,but also gains the active cooperation of the patients,and is helpful for treatment with minimizing adverse effects.

Objective To evaluate the biomechanical effects of using a new injectable calcium phosphate cement to consolidate the fixation of osteoporotic intertrochanteric fracture.Method Five matchod pairs of human cadaver femora were used to produce the model of intertrochanteric fracture.All fractures were fixed with dynamic hip screws(DHS),and divided into two groups.In the CPC consolidation group of each pair,CPC was used to grout the hip screw and to fill the posteromedial defect.All femora were subjected to biomechanical test.Results Under the loading of 500 N,in the CPC consolidation group,the mean axial stiffness is(691.93±18.90)N/mm and the horizontal shear stiffness is(5553.84±27.47)N/mm.The mean lateral and medial strength is(5.15±0.35)MPa and(4.13±0.24)MPa.The torsion stiffness was 0.41 and the ultimate loading is(3580±286)N.In the control group,the mean axiak stiffness is(453.45±19.75)N/mm,the horizontal shear stiffness is(3848.87±22.63)N/mm,the mean lateral and medial strength is(3.12±0.37)MPa and(1.80±0.21)MPa,and,the torsion stiffness is 0.35 and the ultimate loading is(2512±189)N.Consolidation fixation with CPC increased each of the biomechanical efficiency(P＜0.05).Conclusions CPC consolidation of osteoprotic femoral head and the medial defect of intertrochanteric fracture can significantly improve the overall stability and decrease the rate of postoperative complication.
