RESUMEN
Objective To invesgate the influence of aceclofenac to cartilage cell proliferation and substrate metabolism in osteoarthritis.Methods Select 65 cases of patients with osteoarthritis who were treated in Department of Rheumatism and Hematology of Affiliated Hospital of Qinghai University from September 2011 to September 2013.Patients were divided into observation group(n=35)and control group(n=30).The observation group were treated with aceclofenac,while control group were treated with ibuprofen,Compare the efficacy of patients in two group.Compare human articular cartilage cells of 5-bromodeoxyuridine(BrdU)positive rate,the content of glycogen protein(PG)and collagen type Ⅱ in two groups. Results The effective rate of observation group and control group was 74.29%and 73.33% respectively.There was significant difference between the two groups. Compared with control group,the joints pain,joints tenderness,15 meters walking time,daily activity ability(P<0.05).The incidence of adverse reactions of observation group(1 1.43%)was significantly lower than that of control group(P<0.05 ).The difference of BrdU positive rate in two groups had no statistical significance. Ⅱ type collagen content of observation group was significantly higher than that of control group (P <0.05 ).PG of observation group was significantly lower than that of control group(P<0.05).Conclusion The efficacy of aceclofenac is good and the incidence of adverse reactions is low in treatment of osteoarthritis.Aceclofenac can alleviate clinical symptoms of patients by increasing collagen type Ⅱ and decreasing PG.
