ABSTRACT
Objective To discuss the clinic efficacy and its mechanism of action in promoting the cell proliferation of knee osteoarthritis's cartilage corpuscle via modified Duhuo Jisheng Mixture. Methods Totally 60 cases were divided into treatment group and control group by random number table method, with 30 cases in each group. Treatment group was given modified Duhuo Jisheng Mixture, 62.5 mL each time, twice a day, orally, and sulfoglycan sulfate capsules, 1 capsule a day, three times a day, orally; while control group was given diacerein capsules, 1 pill a day, twice a day, orally, and sulfoglycan sulfate capsules, the same as treatment group. Patients were required to do quadriceps muscle systolic and functional exercise, and keep warm. The treatment lasted for 6 weeks. VAS score and WOMAC of the two group were observed before and after treatment. IL-1, NO, Wnt5a, β-catenin, Sox9, Collagen Ⅱ in knee joint fluid were detected. Adverse reactions were monitored. Results Compared with pre-treatment, the contents of IL-1, NO, Wnt5a and β-catenin in two groups were reduces (P<0.05); while the contents of Sox9 and Collagen Ⅱ were raised (P<0.05). The VAS scores and WOMAC were reduced in two groups after treatment (P<0.05). There was no statistical significance between the two group in the above indexes (P>0.05). There were no obvious adverse reactions in both groups.Conclusion Modified Duhuo Jisheng Mixture can reduce inflammatory factors of the joint fluid and inhibit the Wnt signal pathway through regulating the expression of Sox9 and Collagen Ⅱ in the pathway, which can promote the cell proliferation of knee osteoarthritis's cartilage corpuscle and benefit the repairment of cartilage corpuscle in order to relieve pains and improve functions of knee joint.
