从肝论治原发性骨质疏松症的研究进展

骨质疏松症是一种以骨量低下,骨微结构损坏,导致骨脆性增加,易发生骨折为特征的全身性骨病。随着老龄化的加剧,老年人健康问题尤其是骨密度下降引起的骨质疏松越来越引起重视,但是目前原发性骨质疏松症的基础研究和临床诊治主要集中在"肾主骨,生髓"方面,肾虚是其主要病机,而肝对本病的研究和治疗相对较少。原发性骨质疏松症是一个复杂的、多因素导致的疾病,中医整体观要求我们不能一味地治疗某一症状或某一脏腑,要结合传统医学和现代医学分析其病因病机,辨证施治。从中医学肝对骨质疏松的认识到肝与骨质疏松的基础研究再到滋补肝肾的临床疗效,都说明肝对骨质疏松的重要性。补肾兼顾治肝,及早调肝养肝有益于防治骨质疏松症。     

Effect of lipoic acid on cyclophosphamide-induced diabetes and insulitis in non-obese diabetic mice

In an animal model of type I diabetes, the non-obese diabetic (NOD) mouse, the influence of the antioxidant lipoic acid (LA) on the development of diabetes was investigated. Acceleration of diabetes development with cyclophosphamide (CY) resulted in 60% diabetic animals with severely infiltrated islets within 1–3 weeks. Daily administration of lipoic acid for 20 or 30 days around cyclophosphamide treatment suppressed the incidence of diabetes to 30% (P<0.05) and 33%, respectively. Semiquantitative analysis of islet infiltration showed a reduction of severe intraislet infiltration and an increase in the percentage of islets with mild peri-insular and periductular infiltrates (from 8.4 to 29.6 and 25.9%, respectively, P<0.01) after lipoic acid treatment. These results show that the protective effect of lipoic acid on diabetes development correlates with partial suppression of islet inflammation. The anti-inflammatory action of lipoic acid may be due to its ability to scavenge oxygen radicals and to suppress nitric oxide production.

目的验证Cyclin D1及其下游信号蛋白对成骨细胞增殖的调控作用,探讨健骨颗粒促进成骨细胞增殖的作用机制。方法培养成骨样细胞株UMR-106,运用CRISPR/Cas9技术敲减Cyclin D1基因后,将细胞分为基因敲减+生理盐水组(组1)、基因敲减+健骨颗粒组(组2)、病毒空载体细胞(组3,阴性对照)。未行基因敲减的细胞分为正常细胞+生理盐水组(组4)和正常细胞+健骨颗粒组(组5)。分别用生理盐水血清或健骨颗粒含药血清干预各组细胞24、48、72 h,通过CCK8法检测细胞增殖情况,利用Real time PCR检测Cyclin D1、Cyclin E、CDK 2、CDK 4、Rb及E2F-1基因的表达水平。结果经Western-bolt检测表明基因敲减的成骨细胞Cyclin D1蛋白表达明显下降。CCK8法检测结果显示,与组4相比,组5增殖速度变快(P0. 05),组3增殖速度无差异(P0. 05),组1和组2增殖速度均减慢(P0. 05);与组5相比,组2增殖速度减慢(P0. 01);与组1相比,组2增殖速度无统计学意义(P0. 05)。Real time PCR检测结果显示,与组4相比,组5 Cyclin D1、CDK2、CDK4、Cyclin E、Rb及E2F-1 mRNA的表达明显增高(P0. 05或P0. 01),组3表达无统计学意义(P0. 05),组1和组2表达明显降低(P0. 05或P0. 01);与组5相比,组2增殖速度减慢(P0. 01);与组1相比,组2无统计学意义(P0. 05)。结论 Cyclin D1及其下游信号蛋白是调控成骨细胞增殖的关键因素;健骨颗粒可以通过调节Cyclin D1及其下游信号蛋白促进成骨细胞增殖。

上、下坡跑台训练膝骨关节炎模型大鼠关节软骨及炎症因子的变化

BACKGROUND: Different training methods have different effects on primary knee osteoarthritis. OBJECTIVE: To compare the effects of uphill or downhill running on articular cartilage degeneration and inflammatory responses of knee osteoarthritis rats.   METHODS: 108 female Sprague-Dawley rats were randomly divided into six groups: normal control group, ovariectomized group, uphill running group (run & up), downhill running group (run & down), uphill running model group (model & up), downhill running model group (model & down). The rats in the normal control group were raised routinely with no treatment; rats in the ovariectomized group were ovarientomized and raised in routine way; rats in the run & up group and run & down group were subjected to uphill running training on the slop +15° or downhill running training on the slop -15°; rats in the model & up group and model & down group were subjected to uphill running training on the slop +15°or downhill running training on the slop -15° after ovarientomized. Training programs were as follows: 28 m/min, 60 minutes per day, 6 days per week. RESULTS AND CONCLUSION: Compared with the other five groups, in the model & up group, the Mankin’s score was significantly increased, indicating that articular cartilage degeneration occurred, and the peak of carboxy-terminal telopeptide of type II collagen contained in the urine had passed, at 4 weeks after modeling. At 6 weeks, the Mankin’s score of the model & down group was increased to reach the degeneration standard, but it was still lower than that of the model & up group; the expression levels of tumor necrosis factor-α and interleukin-1β in the synovial fluid were significantly higher in the model & up and model & down groups than the other four groups. At 8 weeks, the Mankin’s score and the expression levels of tumor necrosis factor-α and interleukin-1β were further increased in the model & up and model & down groups, especially in the model & up group. These results indicate that treadmill running exercise after ovariectomized can result in articular cartilage injury and local inflammatory responses; compared with the downhill running training, the uphill running training can cause cartilage injury earlier and more efficiently.
