文题释义:
荨麻提取物的作用:与吲哚美辛有类似的抗炎效果。药物与蛋白结合率高,吸收快,起效显著,其基本的机制是抑制环氧化酶,从而抑制产生前列腺素,起到解热、镇痛和抗炎作用。
基质金属蛋白酶3:是基质金属蛋白酶的一种,也被称为间充质溶解素,它具有内切肽链的功能,在与锌与钙离子相互偶联的作用下可降解基质蛋白。基质金属蛋白酶3参与动物多项生理活动并在其中起重要作用,如胚胎形成、组织再生、伤口愈合等;在各项病理过程中也发挥关键性作用,如肿瘤、骨关节炎、心脑血管疾病等;很多细胞被特定刺激后能表达基质金属蛋白酶3,如造骨细胞、血管平滑肌细胞、软骨细胞、内皮细胞、成纤维细胞、角质化细胞等等,各种炎症因子如肿瘤坏死因子和白细胞介素等均可诱导细胞表达基质金属蛋白酶3。而基质金属蛋白酶3的抑制剂是雌激素、糖皮质激素和黄体酮等。

摘要
背景:
荨麻作为一种传统中药,有抗炎、消肿和抗风湿作用,其对骨关节炎的效果目前尚未见相关研究。
目的:探讨不同浓度荨麻对骨关节炎的治疗效果及其机制。
方法:①取18只大鼠剔除表面部分毛,行皮肤刺激实验,分为液体石蜡组、荨麻组和甲醛组,每组6只,分别在大鼠皮肤上面涂石蜡、荨麻胶体和0.8%的甲醛,观察皮肤皮疹和红肿情况;②取30只大鼠,使用木瓜蛋白酶诱导法建立大鼠骨关节炎模型,根据荨麻提取物的浓度,实验分为100 mg/kg组、200 mg/kg组、400 mg/kg组和阳性对照组,每组6只,给药1,2,3周分别测定大鼠左膝关节直径,判断膝关节肿胀情况;用0.6%的醋酸溶液建立大鼠急性疼痛模型,分别给予不同浓度荨麻,对照组给予生理盐水;③对比观察大鼠翻滚及扭转次数,判断荨麻对大鼠止痛效果;给药后第1,2,3周分别用Elisa法测大鼠左膝关节的关节液中白细胞介素1β、肿瘤坏死因子α和基质金属蛋白酶3的含量,检测大鼠关节炎症因子情况。
结果与结论:①荨麻作用于大鼠皮肤后,皮肤表面未见水肿及红疹;②质量浓度为200 mg/kg及400 mg/kg的荨麻与对照组相比能减少关节肿胀、其对关节肿胀的减轻作用和吲哚美辛相比无明显差别;③质量浓度200 mg/kg及400 mg/kg的荨麻能减轻大鼠痛疼,其减轻疼痛效果和吲哚美辛相当;④荨麻在质量浓度为200 mg/kg及400 mg/kg时,与对照组相比能减大少鼠关节液中炎症因子白细胞介素1β、肿瘤坏死因子α和基质金属蛋白酶3的含量;⑤结果表明,荨麻具有抗炎、止痛、消肿和抗骨关节炎的作用。

Abstract:

BACKGROUND: Urtica, as a traditional Chinese medicine, is famous for anti-inflammatory, detumescence and anti-rheumatic effects, but its effect on osteoarthritis remains unknown.
OBJECTIVE: To investigate the therapeutic effect of different concentrations of urtica on osteoarthritis and the underlying mechanism.
METHODS: (1) Eighteen rats were selected, and after their hair was shaved, the rats were divided into three groups (n=6 per group). The rat skin was painted with paraffin, urtica colloid and 0.8% formaldehyde, respectively, and the skin rash and swelling were observed. (2) Thirty rats were selected, and the rat model of osteoarthritis was established by injecting papain, followed by equally allotted into 100, 200, and 400 mg/kg urtica and positive control groups. The diameter of the rat left knee was measured at 1, 2 and 3 weeks after administration to determine the severity of knee swelling. The rat model of acute pain was established with 0.6% acetic acid solution, and then the model rats were subjected to different concentrations of urtica or normal saline (control group). (3) The frequency of rat tumbling and twisting was observed to determine the analgesic effect of urtica. The levels of interleukin-1β, tumor necrosis factor-α and matrix metalloproteinase 3 in the synovial fluid of the left knee joint were detected by ELISA at 1, 2 and 3 weeks after administration.
RESULTS AND CONCLUSION: After urtica administration, no edema or rash appeared on the rat skin surface. Compared with the control group, 200 and 400 mg/kg urtica could reduce joint swelling and pain, showing no significant difference from indomethacin. Compared with the control group, 200 and 400 mg/kg urtica reduced the levels of interleukin-1β, tumor necrosis factor-α and matrix metalloproteinase 3 in the synovial fluid. These results manifest that urtica exerts the effects of anti-inflammation, analgesia, detumescence and anti-osteoarthritis.
