摘　　要：目的:考察红花口服液(HOL)缓解神经病理性疼痛(NP)的药效作用特点并探究其分子作用机制。方法:基于脊神经结扎(SNL)大鼠模型,将健康雄性SD大鼠随机分为假手术组,模型组,HOL低、中、高剂量组(0.5、1.0、2.0 mL·kg^(-1)·d^(-1))及阳性药普瑞巴林组(25 mg·kg^(-1)·d^(-1)),每组6只。在脊神经结扎手术恢复3 d后,连续灌胃给药14 d并采集样本。期间检测各组大鼠的机械痛阈值和冷痛阈值,考察HOL的镇痛作用特点。将假手术组、模型组、HOL高剂量组的海马组织样本进行转录组测序,获取不同组别之间的差异表达基因,并进行通路富集分析,进而,选择与NP密切相关的靶标进行验证,进一步通过分子对接寻找HOL关键活性成分与靶标分子的具体结合位点。此外,检测血清中肿瘤坏死因子-α(TNF-α)和白细胞介素-10(IL-10)的表达水平,评价HOL对NP大鼠的影响。结果:与假手术组比较,模型组大鼠的机械痛阈值及冷痛阈值均明显降低(P<0.05)。与模型组比较,HOL组可有效升高其机械痛阈值及冷痛阈值(P<0.05);转录组分析发现,模型组与假手术组比较共有376个差异表达基因,其中上调基因124个、下调基因252个,模型组与HOL组比较共有194个差异表达基因,其中上调基因33个、下调基因161个。其中,类胰岛素一号生长因子(IGF1)、基质金属蛋白酶-2(MMP-2)、基质金属蛋白酶-14(MMP-14)、酪氨酸激酶受体2(ERBB2)和整合素A5(ITGA5)与NP密切相关。实时荧光定量聚合酶链式反应(Real-time PCR)结果显示,与假手术组比较,模型组大鼠海马中上述各分子的mRNA表达量均显著升高(P<0.01)。与模型组比较,HOL组可有效降低其mRNA表达量(P<0.01)。分子对接结果显示,红花主要活性成分羟基红花黄色素A、山奈酚和槲皮素与上述靶标分子IGF1、MMP-2、MMP-14、ERBB2、ITGA5的氨基酸残基形成稳定的氢键作用力。酶联免疫吸附测定法(ELISA)检测结果显示,�Objective:To investigate the pharmacodynamic characteristics and explore the molecular mechanism of Honghua oral liquid(HOL)in relieving neuropathic pain(NP).Method:Healthy male SD rats were randomly assigned into sham group,model group,low-,medium-,high-dose(0.5,1.0,2.0 mL·kg^(-1)·d^(-1),respectively)HOL groups,and a positive drug(pregabalin,25 mg·kg^(-1)·d^(-1))group,with 6 rats in each group.Spinal nerve ligation(SNL)of L5 was conducted in other groups except the sham group.Drug administration was performed 3 days after the SNL surgery for 2 consecutive weeks,and samples were collected after the end of the administration.During the treatment period,the mechanical pain threshold and cold pain threshold were determined to measure the pain-relieving effect of HOL.Transcriptome sequencing was performed on hippocampal tissue samples from the sham,model,and high-dose HOL groups,and differentially expressed genes between the sham group and the model group as well as the model group and HOL high-dose group were obtained.After pathway enrichment analysis,we selected the targets which were closely related to neuroinflammation for validation,and predicted the specific binding sites of the major active components in HOL with the targets through molecular docking.In addition,the serum levels of tumor necrosis factor-α(TNF-α)and interleukin-10(IL-10)were determined by enzyme-linked immunosorbent assay(ELISA)to evaluate the effect of HOL on neuroinflammation in NP rats.Result:Compared with the sham group,SNL decreased the mechanical pain threshold and cold pain threshold(P<0.05).Compared with the model group,HOL recovered the mechanical pain threshold and cold pain threshold(P<0.05).The transcriptome data showed that 376differentially expressed genes(DEGs)were identified between the model group and the sham group,including124 upregulated genes and 252 downregulated genes,and 194 DEGs between the model group and the high-dose HOL group,including 33 upregulated genes and 161 downregulated genes.Among them,insulin-like gr
