Effects of Activating Blood Circulation to Resolve Blood Stasis and Glucosamine Capsules Therapy on the Expression of Matrix Metalloproteinase in Post-traumatic Knee Osteoarthritis

[Objectives] To observe the clinical effects of activating blood circulation to resolve blood stasis and glucosamine hydrochloride capsules therapy on post-traumatic knee osteoarthritis treatment,to measure the expression of matrix metalloproteinase in post-traumatic knee osteoarthritis patients before and after treatment,and to explore its relevant molecular mechanisms. [Methods]A total of 60 patients with posttraumatic knee osteoarthritis in early stage in Affiliated Hospital of Shannxi University of Chinese Medicine from January 2015 to December2017 were selected and randomly divided into the control group( n = 30) and the observation group( n = 30). The control group was given oral administration of glucosamine hydrochloride capsules for 6 courses of the treatment. The observation group was using the activating blood circulation to resolve blood stasis therapy for 6 courses of treatment. The recovery of traumatic knee osteoarthritis and the symptom of traditional Chinese medicine( TCM) in 2 groups was compared before and after treatment. The symptoms and the quantitative assessment rating scale of knee osteoarthritis,the pain index of knee and the TCM symptom scores were recorded in both groups. And the synovial fluid and serum of patients were collected to detect the expression of matrix metalloproteinase. [Results]The symptoms and the quantitative assessment rating scale of knee osteoarthritis,the pain index of knee and TCM symptom scores of the 2 groups in the 1 st week,the 12 th week and the 24 th week after the treatment were significantly lower than those before the treatment,and the difference was statistically significant( P < 0. 05). Two therapeutic methods had certain therapeutic effects on the recovery from traumatic knee osteoarthritis,and could significantly improve the TCM syndrome. There were better therapeutic effects on oral decoction of traditional Chinese medicine than oral glycosaminoglycans hydrochloride capsules on treating traumatic knee osteogenesis( P < 0. 05). The expression level of MMP3 was decreased significantly in both groups( P <0. 001),while the expression level of MMP13 had no significant change in both groups( P >0. 05). The expression level of MMP1 was decreased significantly in the observation group( P < 0. 001),but there was no significant change in the control group after treatment( P >0. 05). [Conclusions]Two treatment methods have been effective in this clinical study. We found that the expression level of MMP3 was decreased significantly after treatment in 2 therapies,which can be clinically applied.

Expression of matrix metallo-proteinase-28 in human normal cytotrophoblast cells and a choriocarcinoma cell line,JEG-3

There are striking similiarities present between the behavior of invasive placentaL cells and that of invasive cancer cells. Matrix metalloproteinases (MMPs) are one of the most important mediators. MMP-28, the new member of MMPs, was sequenced and identified recently. Expression of MMP-28 mRNA and protein in the cytotrophoblast cells and a choriocarcinoma cell line, JEG-3 cell, was conducted by zymography, RT-PCR and Northern blot. There is MMP-28 mRNA expression in both the cytotrophoblast cells and JEG-3 cells by RT-PCR. The activity of MMP-28 in cytotrophoblast cells was significantly weaker than that in JEG-3 (P 【 0.01) by zymography. Furthermore, mRNA expression of MMP-28 was significantly stronger (P 【 0.001) in JEG-3 than in human cytotrophoblast cells in a time-dependent way by Northern Blot. Our results suggest that MMP-28 may play a role in some of the tissue-remodeling events associated with normal pregnancy and tumor progression.

活动期类风湿关节炎患者血清基质金属蛋白酶-3及其组织抑制剂-1水平的检测和意义

目的研究活动期类风湿关节炎(rheum atoid arthritis,RA)患者血清基质金属蛋白酶-3(m atrix m etalloproteinase3,M M P-3)、金属蛋白酶组织抑制剂-1(tissue inhibitors ofm etalloproteinase1,TIM P-1)的水平及其相关影响因素,探讨M M P-3及TIM P-1在R A的作用机制。方法选择41例初诊活动期RA患者和30名正常健康志愿者,以酶联免疫吸附试验(ELISA)分别检测血清M M P-3及TIM P-1水平,计算M M P-3/TIM P-1,同时测定关节功能、X线、关节肿胀数(SJC)、血沉(ESR)、类风湿因子(R F)、C反应蛋白(CR P)等相关实验室指标。结果活动期R A患者血清M M P-3、TIM P-1明显增高(P<0.01),且以M M P-3增高更为显著,M M P-3/TIM P-1较正常组亦增高(P<0.05)。不同关节功能分级时,上述指标差异无统计学意义(P>0.05),而不同X线分期时,各指标差异有统计学意义(P<0.01或P<0.05)。M M P-3、M M P-3/TIM P-1与SJC(P<0.01)、CRP(P<0.01)、ESR(P<0.05)呈正相关,二者与年龄、病程、晨僵时间、RF无明显相关性(P>0.05)。结论M M P-3、TIM P-1在RA血清中高水平存在,二者比例失衡导致RA发生。M M P-3、M M P-3/TIM P-1的高低可作为反映病情活动及预后的指标,阻断M M P-3高水平有可能成为治疗RA的新途径之一。
