摘要
目的观察关节腔内联合注射富血小板血浆与脐带间充质干细胞治疗轻中度膝关节骨关节炎患者的近期疗效。方法收集聊城市人民医院膝关节骨关节炎患者200例,纳入标准:KellgrenLawrence分级1~3级膝关节骨关节炎患者;排除标准:Kellgren-Lawrence分级4级骨关节炎患者及炎症性关节炎患者等。根据电脑产生的伪随机数字,将研究对象随机分为富血小板血浆(PRP)与脐带间充质干细胞(MSC)联合注射组(PRP+MSC)、单纯PRP注射组(PRP组)、单纯脐带MSC注射组(MSC组)、玻璃酸钠(SH)注射组(SH组),每组各50例。PRP+MSC组关节腔内注射5 ml富血小板血浆与脐带间充质干细胞混合液; PRP组关节腔内注射5 ml富血小板血浆; MSC组关节腔内注射5 ml脐带间充质干细胞; SH组关节腔内注射2. 5 ml的SH及曲安奈德注射液。分别在治疗后1、3、6、12个月进行随访,通过视觉疼痛模拟评分(VAS),美国膝关节协会评分(AKS)评价治疗后膝关节功能的改善情况;采用酶联免疫吸附法检测治疗前后关节液中细胞因子的变化情况;利用MRI的T 2Map序列评价治疗前后关节软骨的变化情况。患者年龄、病程、VAS评分、AKS评分、细胞因子含量等计数资料分析采用单因素方法分析,患者性别比例、病情程度等计数资料分析采用卡方检验。结果 200例患者中,175例完成随访,PRP+MSC组45例,PRP组44例,MSC组43例,SH组43例。4组患者治疗前VAS、AKS及关节液中细胞因子的表达无统计学意义(P> 0. 05)。治疗后1个月,4组患者的VAS评分均较前降低,AKS评分较前升高,组内差异具有统计学意义(t=6. 45,P <0. 01),组间差异无统计学意义(P>0. 05)。3个月后,SH组VAS、AKS趋向于治疗前状态,其余3组未见反弹,PRP+MSC联合注射组优于单纯PRP与MSC治疗组,4组间的差异具有统计学意义(F=7. 84/4. 35,P <0. 01)。治疗后3周,SH组关节液中细胞因子未见明显改变,PRP+MSC组关节液中细胞因子变化水
Objective To observe the short-term efficacy of intra-articular injection of platelet-rich plasma(PRP)and umbilical cord mesenchymal stem cells(MSCs)in the treatment of mild to moderate knee osteoarthritis.Methods A total of 200 cases of osteoarthritis of knee joint in Liaocheng People′s Hospital were collected.Inclusion creteria:Kellgren-Lawrence gradeⅠtoⅢpatients with osteoarthritis of knee joint.Exclusion criteria:Kelgren-Lawrence gradeⅣosteoarthritis patients and inflammatory arthritis patients.According to the pseudo-random numbers generated by the computer,the patients with knee osteoarthritis were randomly divided into PRP+MSC group,PRP group,MSC group and sodium hyaluronate(SH)group,50 cases in each group.In PRP+MSC group,5 ml PRP and umbilical cord MSCs mixture were injected into articular cavity;in PRP group,5 ml PRP was injected into articular cavity;in MSC group,5 ml umbilical cord MSCs were injected into articular cavity;in SH group,2.5 ml SH and triamcinolone acetonide injection were injected into articular cavity.After one,three,six and 12 months of treatment,the improvement of knee joint function was evaluated by visual analogue scale(VAS)and American Knee Association score(AKS);the changes of cytokines in joint fluid were detected by enzyme-linked immunosorbent assay(ELISA),and the Changes in articular cartilage before and after were evaluated by T2 Map sequence of MRI.Measurement data such as age,course,VAS score,AKS score,and cytokine content were analyzed by one-way ANOVA.Enumeration data such as sex ratio and disease degree of patients were analyzed by chi-square test.Results Among the 200 patients,175 were followed up,45 in PRP+MSC group,44 in PRP group,43 in MSC group and 43 in SH group.There was no significant difference in the expression of cytokines in VAS,AKS and synovial fluid between the four groups before treatment(P>0.05).One month after treatment,the VAS scores of the four groups were lower than before,and the AKS scores were higher than before.There was significant diffe
