摘要:


文题释义:

差异蛋白质组学:它是通过寻找各种因素引起的蛋白质表达差异,以解释细胞生理和病理机制。即主要通过比较分析不同状态下或近似物种间蛋白质的表达图谱,实现对体系内代谢调控的动态监测,从而揭示机体对内外界环境变化产生反应的本质规律。
“标本配穴”针刺:湖北中医药大学王华教授创新性地提出标本配穴法,通过以固护正气的腧穴和祛除病邪的腧穴配伍,实现对症状性器官病变进行局部调节(通邪)和机体全身进行整体调节作用(固本),通过局部效应和整体效应的整合,发挥更好的固本通邪作用。


背景:肠易激综合征作为临床常见的消化功能紊乱性疾病,已成为针灸治疗的优势病种,但其作用机制尚未明确。组学技术的方法学特点与针灸作用多靶点、多层次的特点不谋而合,为揭示针灸治疗疾病的作用原理提供可能。

目的:基于蛋白质组学研究腹泻型肠易激综合征(diarrhea-irritable bowel syndrome,IBS-D)的发病机制及“标本配穴”针刺对其的治疗作用机制。
方法:12只3月龄SPF级SD大鼠随机分为正常组、模型组、“标本配穴”针刺组,后2组采用急性应激与慢性应激相结合的方法制备IBS-D大鼠模型;造模成功后针刺组选取双侧足三里穴、双侧内关穴及关元穴进行针刺治疗,频率为120次/min,每隔4 min行针1 min,留针15 min,每隔6 d休息1 d,共持续28 d。正常对照组和模型组大鼠不给予任何干预。通过检测大鼠腹部回撤反射(AWR)压力阈值评价大鼠内脏敏感性;使用基于高效液相色谱-串联质谱联用平台(LC-MS/MS)的非标记蛋白质组学方法进行大鼠结肠黏膜蛋白质组的测定分析;运用MaxQuant、Perseus软件和DAVID、KOBAS、VENNY、STRING在线分析工具进行蛋白质搜库、差异蛋白搜索及其他生物信息学分析;采用网络可视化软件Cytoscape 3.7.1构建关联网络图。

结果与结论:①IBS-D组与正常组相比有47个差异表达蛋白;差异蛋白功能分析显示,IBS-D的致病机制与能量代谢的异常加剧、结肠运动功能失衡、内脏敏感性的增加等有关;与IBS-D疾病相关的重要靶标蛋白包括:Atp5a1、Atp5c1、Idh3b、Atp2a3、Pdhb、Ppp1ca及Mapk3。②“标本配穴”针刺组与模型组相比较有61个差异表达蛋白,其中针刺逆转了IBS-D 9个差异表达蛋白的上调和9个差异表达蛋白的下调。③生物信息学分析结果表明“标本配穴”针刺对IBS-D的干预效应具有多靶点、多途径、多通路的特点,能够逆转IBS-D对正常能量代谢的损伤,同时能发挥抗氧化应激保护及抗炎的作用而达到缓痛、调节肠道失衡及肠屏障功能的治疗效果;与“标本配穴”针刺干预机制相关的重要靶点为Atp5a1、Atp5c1、Pdhb、Sars、Uqcrc2、Prdx2、Prdx4、Ppp1ca、Manf和Tmsb4x3。④该研究从整体蛋白质表达的角度初步明确了IBS-D致病的分子机制及“标本配穴”针刺对IBS-D的潜在作用机制,为“标本配穴”选穴配伍奠定了基础。

Abstract: BACKGROUND: As a common clinical digestive disorder, irritable bowel syndrome becomes an advantageous disease of acupuncture treatment. However, the therapeutic mechanisms remain unclear. The methodological characteristics of omics coincide with the multi-target and multi-level characteristics of acupuncture, providing the possibility of revealing the principle of acupuncture in the treatment of the disease.
OBJECTIVE: To investigate the pathogenesis of irritable bowel syndrome with diarrhea (IBS-D) and the effect of acupuncture at the combined points (selected based on etiologies and symptoms) on IBS-D based on proteomics. 
METHODS: Twelve 3-month-old male Sprague-Dawley rats were randomly divided into three groups: a control group, an IBS-D model group and an acupuncture group. The IBS-D rat models were prepared using the CAS method. After successful modeling, bilateral Zusanli points, bilateral Neiguan points and Guanyuan points were selected for acupuncture treatment in the acupuncture group, with a frequency of 120 times/minute, 1 minute of acupuncture every 4 minutes, and 15 minutes of needle retention, at an interval of 1 day every 6 days, for 28 days in total. Rats in the normal control group and the model group were not given any intervention. The pressure threshold of rat abdominal retraction reflex was measured to evaluate the visceral hypersensitivity of rats. Proteomics analysis was performed using the liquid chromatography-tandem mass spectrometry -based platform. MaxQuant software, Perseus software and DAVID, KOBAS, VENNY, STRING online tools were used for the bioinformatics analysis of proteomic data. Visualization analysis was done using Cytoscape 3.7.1 software. 
RESULTS AND CONCLUSION: There were 47 differentially expressed proteins between the IBS-D model and control groups. Function analysis of differentially expressed proteins revealed that the pathogenic mechanism of IBS-D was associated with abnormal energy metabolism, the imbalance of colon motor function and increased visceral sensitivity. Important proteins related to IBS-D pathogenesis included Atp5a1, Atp5c1, Idh3b, Atp2a3, Pdhb, Ppp1ca and Mapk3. Sixty-one differentially expressed proteins were identified between the acupuncture group and IBS-D model group. Acupuncture at the combined points reversed the up-regulation of nine differentially expressed proteins and the down-regulation of nine differentially expressed proteins. Bioinformatics analysis revealed that acupuncture at the combined points for IBS-D could function via multi-targets and multi-pathways, reverse the damage of energy metabolism caused by IBS-D, and play a role against oxidative stress and inflammation, thereby relieving pain and regulating the imbalance of intestinal function. Important proteins related to acupuncture effects included Atp5a1, Atp5c1, Pdhb, Sars, Uqcrc2, Prdx2, Prdx4, Ppp1ca, Manf and Tmsb4x3. All these findings preliminarily illustrate the potential molecular mechanisms of IBS-D and the effect of acupuncture at the combined points in the treatment of IBS-D at the protein level, which provide a basis for the clinical application of acupuncture at the combined points.
