摘要
目的研究富血小板血浆联合强骨胶囊对大鼠骨质疏松性骨折骨愈合的影响。方法80只未交配、3月龄雌性健康SD大鼠作为研究对象,将以上大鼠分为空白组(K组)、PRP组(P组)、强骨胶囊组(Q组),联合组(L组),每组大鼠20例,分析四组大鼠的骨痂显微形态、组织形态学以及生物力学指标之间的差异。结果经过两两比较,联合用药组患者的骨小梁体积、数量、厚度、连接密度高于单独用药组,分离度、表面积体积比低于对照组(P<0.05);联合用药组患者的最大载荷、结构能量吸收、材料最大应力、材料能量吸收高于单独用药组;经过两两比较,联合用药组患者的骨架面积及软骨或骨性骨痂面积比高于单独用药组。结论富血小板血浆联合强骨胶囊通过对骨折部位骨质密度以及骨质强度的增强,大鼠骨质疏松性骨折骨愈合情况良好。
Objective To study the effect of platelet rich plasma combined with Qianggu capsule on osteoporotic fracture healing in rats.Methods 80 unmatched and 3-month-old female healthy SD rats were divided into blank group(group K),PrP group(group P),Qianggu capsule group(group Q),combined group(group L)and 20 rats in each group.The differences of callus morphology,histomorphology and biomechanical indexes among the four groups were analyzed.Results After comparing the two groups,the volume,quantity,thickness and connection density of trabecula in the combined group were higher than those in the single drug group,and the separation and surface area volume ratio were lower than those in the control group(P<0.05);the maximum load,structural energy absorption,material maximum stress and material energy absorption in the combined group were higher than those in the single group;after comparing the two groups,in the combined group,skeleton area and area ratio of cartilage or osteotylus in the treatment group were higher than that in single-drug group.Conclusion Platelet rich plasma combined with Qianggu capsule may enhance the bone density and bone strength of the fracture site,and the osteoporotic fracture healing in rats is good.
