Abstract： This paper adopts fuzzy theory to create the fuzzy parameter of the return by history data of similar products and uses Mean-variance model to carve and estimate return and risk. Moreover, based on adapting Cobb-Douglas production function to building the multi-criteria optimal function, the optimal sequence strategy model is built. Then, integrating the fuzzy simulation and multi-criteria 0-1 genetic algorithm can solve the model. Lastly, the numeral example shows the optimal strategy that is derived by model is superior to the strategy that only other five sequence strategies.

Abstract： Objective To evaluate the effects a lithium chloride-doped calcium phosphate cement (Li/CPC) on promoting tibial defect repair in rats. Methods Twenty 6-month-old female SD rats randomized into Li/CPC (n=10) and CPC control (n=10) groups. Surgery was performed to create bone defects at the bilateral tibia, which were filled with either of the cement. Five rats from each group were sacrificed at 1 and 2 months after the surgery for micro-CT examination and HE staining of the tibia. Results Micro-CT showed better repair of bone defects in Li/CPC group, which had a significantly higher new bone volume fraction (BV/TV) and a lower trabecular separation/spacing (Tb.Sp) than the control group (P<0.05). HE staining showed an earlier appearance of fiber and osteoid callus in Li/CPC group than CPC control group. The number and quality of bone healing was significantly higher in Li/CPC group than in CPC group. Conclusion Li/CPC possessed better osteoinductivity and can significantly promote bone defect repair in rats.
