目的:探究大脑初级体感皮层(S1)脑区趋化因子CXC配体1(CXCL1)及趋化因子CXC受体2(CXCR2)参与针刺镇痛的作用机制,进一步揭示针刺镇痛的神经-免疫学机制。方法:将热痛阈值相对稳定的BALB/c小鼠足底注射0.05 mL完全弗氏佐剂(CFA)建立佐剂... 目的:探究大脑初级体感皮层(S1)脑区趋化因子CXC配体1(CXCL1)及趋化因子CXC受体2(CXCR2)参与针刺镇痛的作用机制,进一步揭示针刺镇痛的神经-免疫学机制。方法:将热痛阈值相对稳定的BALB/c小鼠足底注射0.05 mL完全弗氏佐剂(CFA)建立佐剂性关节炎(AIA)模型后,随机分为单纯荧光组和荧光标记CXCL1组,每组2只。荧光标记CXCL1组小鼠尾静脉注射AF750荧光标记CXCL1重组蛋白,并通过小动物活体成像技术,观察荧光及荧光标记CXCL1在AIA小鼠体内的主要富集脏器及脑的荧光富集情况。另取热痛阈值相对稳定的Wistar大鼠,右足底注射0.1 mL CFA建立AIA模型,随机分为模型组、针刺组,每组12只,取12只Wistar大鼠右足底注射等体积的0.9%氯化钠溶液作为盐水组。针刺组大鼠针刺“足三里”1次/d,针刺持续7 d,治疗结束后采用热痛仪测量大鼠右侧足底热缩足潜伏期即热痛阈值;利用ELISA、免疫荧光及实时荧光定量PCR技术,检测文献报道的可能表达CXCR2及阿片肽受体的多个疼痛相关脑区CXCL1蛋白含量及S1脑区CXCL1阳性细胞数与mRNA表达水平,以期探明前期研究结果中针刺后升高的血清CXCL1的作用脑区;采用ELISA法检测各组大鼠S1脑区中CXCR2蛋白含量,采用实时荧光定量PCR法检测S1脑区中CXCR2、μ-阿片肽受体(MOR)的mRNA表达,采用免疫荧光双标法将CXCR2分别与星形胶质细胞标记物胶质纤维酸性蛋白(GFAP)、神经元标记物NeuN及MOR共染,检测CXCR2在S1脑区中的表达细胞及是否与MOR共表达。结果:与单纯荧光组相比,荧光标记CXCL1组小鼠脑组织中有较强的荧光信号。与盐水组相比,模型组大鼠右侧足底热痛阈值均明显降低(P<0.01),S1脑区中CXCR2 mRNA表达升高(P<0.05);与模型组相比,针刺组第2~7天热痛阈值、S1脑区中CXCL1蛋白含量、CXCR2蛋白含量及mRNA表达、MOR mRNA表达均升高(P<0.05,P<0.01);针刺组大鼠S1脑区中CXCR2分别与NeuN及MOR有共染,表明CXCR2存在于神经元和MOR阳性神经元中,而不存在于GFAP阳性星形胶质细胞中。结论:针刺改善AIA大鼠炎性痛的作用机制可能与其上调S1脑区中CXCL1蛋白含量及S1脑区神经元上的CXCR2、促进神经元表达MOR有关。 展开更多

The scientific evidenee of acupuncture studies has been improved in recent years,and one of the important manifestations is that more and more acupuncture clinical trials and mechanism researches have been published in the source periodicals of Science Citation Index(SCI).This study summarized the dominant diseases of acupuncture focusing on of acupuncture efficacy and mechanisms,and discussed the existing problems,highlight!ng the directi on of future developme nts.Most clinical studies were published in journals with journal impact factor(JIF)score of 10 or above,and majority of the basic researches had JIF scores of 5 to 10.The above literature were further divided according to the International Classification of Diseases(ICD).The most concerned diseases in these articles were neurological diseases,musculoskeletal system and connective tissue diseases,tumor and digestive system diseases.The therapeutic effect and mechanism of acupuncture on each kind of disease were summarized.The results showed that the therapeutic effect of acupuncture on nerve injury focused on the anti-oxidation pathway,neuroprotective and anti-inflammatory processes.The antiinflammatory effect also played an important role in the treatme nt of musculoskeletal diseases.The an algesic effect was underlined in most of these studies.Clinical trials were well carried out on acupuncture curative effect of tumor complications and side effects of chemo-radiotherapy,but the potential mechanisms have not been clarified.Somato-visceral reflex was suggested to be strongly associated with the effects of acupuncture changing the motor activity of the gastrointestinal tract.Functional magnetic resonance imaging studies indicated that non-specific effects play important roles in acupuncture analgesia.Lines of evidenee have pointed out that the regulation of neuro-endocrine-immune networks may be a common switch of acupuncture on different nerve system diseases. 展开更多

Due to its own internal laws of development,Chinese medicine(CM)seems more inclined to empirical medicine in a relatively long historical period.It is considered to be lacking objective and unified clinical practice guidelines(CPGs),and the difficulties in diagnosis and therapeutic effect evaluation comes with it,have restricted its further inheritance,development and international communication.Over the years,our research group has been committed to improving the standardization theory and methodology of CM,also perfecting relative techniques for further application,which are all based on the stratified evidence scoring method.We have already applied this method to 45 issued guidelines,including 5 national guidelines,3 industrial guidelines,and 37 formulation/revision social organization guidelines.The stratified evidence scoring method has been recognized and used widely.It helps scholars and applicators to study,formulate,publish and popularize the acupuncture therapy clinical practice guidelines better,thus further promotes the development of acupuncture therapy. 展开更多
