目的:观察生地黄配伍玄参对DN大鼠病理过程中肾脏微炎症状态的影响。方法:将50只SD大鼠适应性饲养1周后，随机选取10只作为空白对照组，其余采取STZ腹腔注射联合高脂饲料诱导DN模型，4周后将造模成功的大鼠按随机数字表法分为模型组、生地黄玄参组（5.25 g/kg）和二甲双胍组（200 mg/kg），每组10只。给药8周后，采用血糖仪检测大鼠空腹血糖；苯索氯铵比浊法检测尿微量白蛋白水平；ELISA法检测血清中胱抑素、TNF-α、IL-6、超敏C反应蛋白（hs-CRP）水平；采用HE、Masson、过碘酸希夫反应（PAS）染色观察肾脏病理形态改变；采用Western blot法检测肾组织单核细胞趋化蛋白-1（MCP-1）、NF-κB、p-NF-κB蛋白表达。结果:与模型组比较，生地黄玄参组大鼠体重降低（n P<0.05），空腹血糖［（18.06±5.69）mmol/L比（29.42±0.63）mmol/L］、24 h尿蛋白定量［（11.02±1.77）mg/d比（31.61±0.65）mg/d］、血清胱抑素［（208.16±12.07）ng/ml比（278.05±19.33）ng/ml］、TNF-α［（9.13±1.46）pg/ml比（73.16±8.30）pg/ml］、IL-6［（4.27±1.07）pg/ml比（12.04±1.57）pg/ml］、hs-CRP［（219.36±22.02）ng/ml比（266.97±15.80）ng/ml］水平降低（n P<0.05），肾组织p-NF-κB［（0.49±0.07）比（0.84±0.12）］、MCP-1［（0.44±0.02）比（0.64±0.11）］蛋白表达降低（n P<0.05）。n 结论:生地黄配伍玄参可通过抑制NF-κB的过度活化，降低MCP-1相关蛋白表达，减轻肾脏微炎症状态，发挥保护肾脏、治疗DN的作用。“,”Objective:To explore the effect of n Rehmanniae Radix combined with n Scrophulariae Radix on renal microinflammation in diabetic nephropathy (DN) rats.n Methods:50 Sprague Dawley (SD) rats were adaptively fed for 1 week, and then 10 rats were randomly selected as the blank control group, and the rest were treated with STZ intraperitoneal injection combined with high-fat diet to induce DN model. After 4 weeks, the successful modeled rats were randomly divided into model group, Rehmannia glutinosa Scrophularia group (5.25 g/kg) and metformin group (200 mg/kg), with 10 rats in each group. After 8 weeks of administration, fasting blood glucose was measured by blood glucose meter; microalbuminuria was measured by benzalkonium chloride turbidimetry; serum cystatin, TNF-α, IL-6 and hs-CRP levels were measured by ELISA kit; renal pathological changes were detected by HE staining, Masson staining and PAS staining; the expression of MCP-1, NF-κB (total) and p-NF-κB protein in renal tissue was detected by Western blot.Results:Compared with the model group, the body weight of rats in DHXS group was significantly decreased (n P<0.05). The content of fasting blood glucose[(18.06 ± 5.69) mmol/Ln vs. (29.42 ± 0.63)mmol/L], 24-hour urine protein [(11.02 ± 1.77)mg/d n vs. (31.61 ± 0.65)mg/d], serum cystatin [(208.16 ± 12.07)ng/ml n vs. (278.05 ± 19.33)ng/ml], TNF-α [(9.13 ± 1.46)pg/ml n vs. (73.16 ± 8.30)pg/ml], IL-6[(4.27 ± 1.07)pg/ml], hs-CRP[(219.36 ± 22.02)ng/mln vs. (266.97 ± 15.80)ng/ml] in DHXS group were significantly decreased (n P<0.05), and the expression level of p-NF-κB (0.49 ± 0.07n vs. 0.84 ± 0.12) and MCP-1 (0.44 ± 0.02 n vs. 0.64 ± 0.11) in renal tissue of rats in DHXS group were significantly reduced (n P<0.05).n Conclusion:Rehmanniae Radix combined with n Scrophulariae Radix can protect kidney by inhibiting the over activation of NF-κB, and reducing the expression of MCP-1 related protein to reduce renal micro inflammation.n
