研究目的:

本研究以功能性便秘患者为研究对象,观察针刺对FC患者临床症状改善的同时,采用Solexa高通量测序技术筛选FC患者与健康受试者差异表达的miRNA,对测序结果进行RT-qPCR验证,探索与功能性便秘发生发展相关的miRNA。选用16S rRNA高通量测序,对比分析针刺前后FC患者肠道菌群结构和多样性的差异,筛选出与针刺效应相关的最为显著的差异性肠道菌群与miRNA表达,揭示针刺治疗FC的临床疗效与调节miRNA和肠道菌群的相关性,为针刺治疗功能性便秘的临床应用提供指导。

Objectives of Study:

In this study, the patients with functional constipation were selected as the research object, and the clinical symptoms of FC patients were improved by acupuncture. At the same time, the differentially expressed miRNAs of FC patients and healthy subjects were screened by Solexa high-throughput sequencing technology, and the sequencing results were verified by RT-qPCR to explore the miRNAs related to the occurrence and development of functional constipation. 16S rRNA high-throughput sequencing was used to compare and analyze the differences in the structure and diversity of intestinal flora before and after acupuncture in FC patients. The most significant differences in intestinal flora and miRNA expression related to acupuncture effect were screened. The correlation between the clinical effect of acupuncture on FC and the regulation of miRNA and intestinal flora was revealed, which provided guidance for the clinical application of acupuncture in the treatment of functional constipation.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

CRF表由研究人员进行采集并管理。临床数据采用SAS或SPSS统计分析系统进行统计;提取miRNA后,采用Solexa高通量测序技术对miRNA进行测序,测序后挑选符合研究要求的miRNA分子在15例测序样本里进行初步PCR验证,并将与测序结果相符的miRNA分子在剩余25例样本中进行PCR扩大验证;肠道菌群数据采用PE300测序策略,在Illunima Miseq平台上进行高通量测序。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

CRF tables were collected and managed by researchers. The clinical data were analyzed by SAS or SPSS statistical analysis system; miRNA; After the miRNA was extracted, it was sequenced by Solexa high-throughput sequencing technology. After sequencing, miRNA molecules meeting the research requirements were selected for preliminary PCR verification in 15 sequencing samples, and the miRNA molecules consistent with the sequencing results were amplified for PCR verification in the remaining 25 samples; PE300 sequencing strategy was used for high-throughput sequencing of intestinal flora data on illunima Miseq platform.
