目的:探讨补肾生骨汤调节miR-135b-5p/Runt相关基因2(RUNX2)信号轴对股骨头无菌性坏死(ONFH)大鼠的影响.方法:将SD大鼠随机分为假手术(Sham)组、ONFH组、低/中/高剂量补肾生骨汤(0.13,0.26,0.52 g/mL,L/M/H-补肾生骨汤)组、H-补肾生骨汤+miR-135b-5p agomir 组、H-补肾生骨汤+agomir-NC组,采用液氮冷冻法制备ONFH大鼠模型;苏木精-伊红(HE)染色观察股骨头组织病理改变;检测血浆中纤维蛋白原(FIB)、血管内皮生长因子(VEGF)、一氧化氮合成酶(NOS)、骨钙素(BGP)水平;RT-qPCR仪、Western Blot法分别检测股骨头组织中miR-135b-5p、RUNX2表达水平;双荧光素酶实验分析miR-135b-5p与RUNX2的靶向关系.结果:与Sham组比较,ONFH组股骨头组织发生区域性缺损,骨小梁稀疏、行走不规则,空骨陷窝增多明显;血浆中FIB表达升高,VEGF、NOS、BGP表达降低(P<0.05);经L/M/H-补肾生骨汤干预后,上述情况均改善,且经H-补肾生骨汤干预改善更明显;在H-补肾生骨汤干预的基础上增加miR-135b-5p agomir干预后,H-补肾生骨汤干预的改善作用被削弱.与Sham组比较,ONFH组股骨头组织中miR-135b-5p表达升高,RUNX2表达降低(P<0.05);经H-补肾生骨汤干预后,miR-135b-5p表达降低,RUNX2表达升高(P<0.05);在H-补肾生骨汤干预的基础上增加miR-135b-5p agomir干预后,miR-135b-5p表达升高,RUNX2表达降低(P<0.05).双荧光素酶实验结果显示,miR-135b-5p与RUNX2存在靶向关系.结论:补肾生骨汤能促进ONFH大鼠股骨头组织修复,可能与下调miR-135b-5p进而靶向上调RUNX2有关.
Objective:To analyze the healing effect of paeoniflorin on the wound of rats and regulation of NGF/Akt/GSK3β pathway on rats with diabetic foot.Methods:60 rats were randomly divided into normal control group, model group, low, medium and high dose paeoniflorin groups, 12 rats in each group. Diabetic foot model was established by intraperitoneal injection of streptozotocin (STZ) and electrothermal scald. Paeoniflorin groups were injected intraperitoneally with 20 mg/kg, 40 mg/kg and 80 mg/kg paeoniflorin, once a day for 21 days. The wound healing rate of the rats was measured. The fasting blood glucose was measured by blood glucose meter, HbAlc, TC, LDL-C and TG were measured by automatic biochemical analyzer. Serum CRP, IL-6, IL-1β and TNF-α were measured by ELISA. The histopathological changes of the wound were examined by HE staining, the levels of NGF, Akt and GSK3 β mRNA in skin tissue were measured by real-time quantitative polymerase chain reaction (RTq-PCR), the protein and phosphorylation levels of NGF, Akt and GSK3 β were determined by Western blot.Results:Compared with the model group, the healing rate the rats' wounded surface in the low, medium and high dose groups of paeoniflorin was increased ( P<0.05). The levels of fasting blood glucose, HbAlc, TC, LDL-C, TG levels and serum CRP, IL-6, IL-1β, TNF-α was decreased ( P<0.05). The expression of rat skin tissue NGF mRNA (0.83±0.12, 3.17±0.11, 4.54±0.25 vs. 0.31±0.06), Akt mRNA (1.71±0.14, 2.96±0.27, 4.10±0.34 vs. 0.97±0.20) increased ( P<0.05), expression of GSK3β mRNA (4.28±0.35, 2.82±0.14, 1.22±0.33 vs. 7.62±0.43) decreased ( P<0.05), expression of NGF (0.46±0.02, 0.70±0.04, 0.87±0.04 vs. 0.30±0.06), Akt (0.51±0.09, 0.63±0.03, 0.79±0.06 vs.0.41±0.05),p-NGF/NGF (0.47±0.06, 0.61±0.04, 0.83±0.07 vs. 0.25±0.03), p-Akt/Akt(0.54±0.08, 0.83±0.11,0.96±0.07 vs. 0.13±0.05) was increased( P<0.05), the expression of GSK3β (0.67±0.05, 0.54±0.04,0.45±0.03 vs. 0.86±0.05), and the ratio of p-GSK3β/GSK3β (0.78±0.09, 0.64±0.07, 0.42±0.07 vs. 0.97±0.05) was decreased ( P<0.05), and the changes of each index were dependent on the dose of paeoniflorin. Conclusion:Paeoniflorin can regulate the level of blood glucose and blood lipid, inhibit the level of serum inflammatory factors and promote the healing of the wound in diabetic foot rats, and its mechanism may be related to the regulation of NGF/Akt/GSK3β pathway.
