Based on the experience and advantage in resistance to infection of traditional Chinese medicine, in view of the "resistance to pathogen infection" this major disease, serious harm people's health to the drug-resistant bacteria are basic pathogenesis of TCM in many link, multi-level systematic compatibility of traditional Chinese medicine research. Represented by with centralizer and eliminate pathogenic Chinese medicine as research object, with the TLR-4/NF-κB pathway as the breakthrough point,through the comparative analysis of centralizer, pure evil spirits, foster the intervention effects on TLR-4/NF-κB pathway,the influence of early and late inflammatory, pro-inflammatory and anti-inflammatory factor expression, reveal the centralizer and eliminate pathogenic the compatibility of Chinese traditional medicine and its regulation in different periods, different inflammatory factors intrinsic relations, a clear regulatory mechanism of Chinese medicine compatibility of the inflammatory response and intervention targets, for clinically drug-resistant bacteria infections compatibility of traditional Chinese medicine to provide effective guidance, and to develop with independent intellectual property rights and market competition both at home and abroad the specificity of traditional Chinese medicine drugs, fill the drug-resistant bacteria resistant blank in the field of traditional Chinese medicine compound preparations to provide reliable experimental basis.
基于中医药在抗感染方面的丰富经验和优势,针对“耐药性病原菌感染”这一严重危害人民健康的重大疾病,切合耐药菌感中医基本病机开展多环节、多层次、系统化的中药调控作用研究。以前期研究扶正透邪方中的扶正与透邪中药为研究对象,以TLR-4/NF-κB通路为切入点,通过比较分析单纯透邪、早期扶正、延迟扶正、递增剂量扶正、递减剂量扶正对TLR-4/NF-κB通路、早期/晚期炎症因子、促炎/抗炎因子、免疫自稳调节因子表达的影响,揭示在清热透邪的基础上早期扶正与延迟扶正,以及随着耐药菌感染的发生、发展不同力度扶正对不同时期、不同作用炎症因子的调控作用,明确耐药菌感染时清热透邪配伍扶正的时机,以及不同时期的扶正力度,为临床上抗耐药菌感染中药的配伍选择提供有益的指导,并为研制出具有自主知识产权和国内外市场竞争力的特异性中药新药,填补抗耐药菌中药复方制剂领域的空白提供可靠的实验依据。
本课题基于中医药在抗感染方面的丰富经验和优势,针对“耐药性病原菌感染”这一严重危害人民健康的重大疾病,切合耐药菌感中医基本病机开展多环节、多层次、系统化的中药调控作用研究。以前期研究扶正透邪方中的扶正与透邪中药为研究对象,通过比较分析单纯透邪、早期扶正、延迟扶正、递增剂量扶正、递减剂量扶正对TLR-4/NF-κB通路、早期/晚期炎症因子、促炎/抗炎因子、免疫自稳调节因子表达的影响。结果表明,3h时,单纯透邪组、早期扶正组和延迟扶正组TNF-α水平高于模型组(P<0.05),与模型组相比,早期扶正组大鼠血清TLR-4水平降低(P<0.05),延迟扶正组大鼠血清TLR-4水平升高(P<0.05)。1d时,单纯透邪组、延迟扶正组HMGB1含量均明显高于模型组(均P<0.05),延迟扶正组HMGB1含量明显高于早期扶正组(P<0.05)3d时,早期扶正组和延迟扶正组TNF-α水平低于模型组和单纯透邪组(P<0.05),同时早期扶正组和延迟扶正组IL-10水平高于模型组(P<0.05),早期扶正组HMGB1含量明显高于模型组(P<0.05),早期扶正组、延迟扶正组HMGB1含量均明显高于单纯透邪组(均P<0.05),延迟扶正组HMGB1含量明显低于早期扶正组(P<0.05),感染后3d与模型组相比,单纯透邪组大鼠血清TLR-4水平升高(P<0.05),早期扶正组较单纯透邪组大鼠血清TLR-4水平降低(P<0.05)。5d时,早期扶正组TIPE2水平高于模型组(P<0.05),延迟扶正组HMGB1含量明显低于模型组(P<0.05)。7d时,早期扶正组和延迟扶正组IL-10水平低于模型组(P<0.05),单纯透邪组和延迟扶正组TIPE2水平低于模型组(P<0.05)。上述结果揭示了在清热透邪的基础上早期扶正与延迟扶正,以及随着耐药菌感染的发生、发展不同力度扶正对不同时期、不同作用炎症因子的调控作用,明确了耐药菌感染时清热透邪配伍扶正的时机,以及不同时期的扶正力度,为临床上抗耐药菌感染中药的配伍选择提供有益的指导,并为研制出具有自主知识产权和国内外市场竞争力的特异性中药新药,填补抗耐药菌中药复方制剂领域的空白提供了可靠的实验依据。
