摘要:目的:观察电针大肠俞募穴"天枢""大肠俞"对慢传输型便秘(STC)大鼠肠道传输功能的改善情况,通过检测大鼠结肠组织胶质细胞源性神经营养因子(GDNF)的表达以及GDNF基因启动子区CpG岛甲基化状态,探讨电针治疗STC的可能机制。方法:雄性SD大鼠随机分为正常组、盐水组、模型组和电针组,每组16只。采用15 mg/mL复方地芬诺酯混悬液灌胃(10 mL·kg(-1)·d(-1)·d(-1))复制STC大鼠模型。盐水组予同等剂量的0.9%氯化钠溶液灌胃。电针组电针双侧"天枢""大肠俞",每次15 min, 1次/d,连续14 d。观察大鼠排便情况并检测大鼠肠道传输功能;采用透射电镜观测结肠组织Cajal间质细胞(ICC)超微结构;Western blot法、实时荧光定量PCR法检测结肠组织中GDNF蛋白、mRNA的表达;重亚硫酸盐测序法检测结肠组织GDNF基因启动子区CpG岛甲基化状态。结果:与正常组、盐水组比较,模型组大鼠24 h排便量下降(P<0.01),粪便性状评分降低(P<0.05),小肠推进率下降(P<0.01),ICC形态结构遭到破坏,结肠组织GDNF蛋白及mRNA表达降低(P<0.01),GDNF基因启动子区CpG岛甲基化阳性率升高(P<0.05)。与模型组比较,电针组大鼠24 h排便量增多(P<0.01),粪便性状评分升高(P<0.05),小肠推进率明显升高(P<0.01),损伤的ICC超微结构得到部分修复,结肠组织GDNF蛋白及mRNA表达升高(P<0.05),GDNF基因启动子区CpG岛甲基化阳性率降低(P<0.05)。结论:电针大肠俞募配穴可促进结肠组织GDNF的表达,有效改善STC大鼠的便秘症状,修复结肠组织超微结构,从而调整肠道传输功能,其中结肠组织GDNF基因启动子区甲基化状态的改变可能是电针大肠俞募配穴治疗STC的重要机制之一。Objective To observe the effect of electroacupuncture(EA) of “Tianshu”(ST25) and “Dachangshu”(BL25) on the intestinal transit function, expression level of glial cell-derived neurotrophic factor(GDNF) and methylation level of GDNF gene promoter region in colon tissue of rats with slow transit constipation(STC), so as to explore its mechanisms underlying improvement of STC.

Methods Literature about indications and acupoint prescriptions of SP1 published before October of 1949 were retrieved from books Chinese Medical Dictionary(5(th) edition) and Collection of Modern Medical Journals of Traditional Chinese Medicine, and those published from October 1(th) edition) and Collection of Modern Medical Journals of Traditional Chinese Medicine, and those published from October 1(st) of 1949 to January of 2021 retrieved from databa-ses of CNKI, Wanfang, VIP, CBM, Web of Science and Pubmed by using key words of Yinbai(SP1),“Guilei”(鬼垒),“Guiyan”(鬼眼) and Jing(Well)-point of Spleen Meridian, followed by screening the data and establishing a SQL Server database after standardized processing. Then, the descriptive analysis, clustering analysis and association rule analysis were conducted by using Gephi visualization software, SPSS Statistics 25.0 and SPSS Modeler, separately. Results Before October of 1949, the single SP1 acupoint was usually used to treat 12 types of diseases(mainly the internal diseases as asthma, abdominal distension, vomiting, etc.), and the compound prescriptions of SP1 were usually used to treat 20 types of diseases(mainly the internal diseases as insomnia and dreamful sleep, blood syndrome, etc.), and its adjunct acupoints belong to the first three meridians: the Foot Yangming Stomach Meridian, Foot Taiyang Bladder Meridian and Foot Taiyin Spleen Meridian. After October of 1949, the single SP1 was used to dominantly treat 2 types of diseases(mainly the gynecological diseases as metrorrhagia and metrostaxis, and hypermenorrhea, etc.), and the compound prescriptions of SP1 were frequently used to treat 10 diseases(metrorrhagia and metrostaxis, sequela of apoplexy, mental disorders, insomnia and dreamful sleep, etc.), and the adjunct acupoints of compound prescriptions belong to the first three meridians, namely the Foot Taiyin Spleen Meridian, Concept Vessel and Foot Yangming Stomach Meridian. Before and after October of 1949, the adjunct acupoints with the highest degree of correlation were Lidui(ST45), Shaoshang(LU11), Zusanli(ST36), Sanyinjiao(SP9), and Guanyuan(CV4). Cluster analysis showed that 9 effective clusters obtained may be used as potential prescriptions of SP1, and association rule analysis displayed that the first three strongly connected acupoint matching groups were: SP1-ST45, SP1-LU11, and SP1-ST36 frequently used before October of 1949, and SP1-SP9, SP1-ST36 and SP1-CV4 employed after October of 1949. Conclusion Data mining technology reveals that acupoint SP1 alone is mainly used to treat internal diseases before 1949, and gynecological diseases after 1949; and compound acupoint recipes of SP1 are mainly to treat the internal diseases before 1949, and the gynecological diseases and mental disorders after 1949 in China. The frequently employed adjunct acupoints of SP1 are ST45, LU11, ST36, SP9 and CV4 both before and after 1949.
