舌苔菌群与中医病证诊断的文献研究与思考

摘要：人体与舌苔微生物相互依存，相互影响。现今对舌苔微生态系统的研究主要集中于舌苔菌群。体质、疾病等诸多因素都可对舌苔产生影响，此时舌苔中菌群会有怎样的变化？菌群变化是否具有疾病诊断意义？这些问题已经受到关注和研究。文献研究显示，目前有关舌苔菌群病证诊断研究主要围绕中医心系疾病、脾系疾病和肺系疾病等进行，诸多研究表明脾系疾病湿热证患者，舌苔存在菌群失调，舌苔中细菌总数较正常人群明显升高，心系、肺系疾病暂无较为一致的结论。文献研究表明舌苔菌群的变化与病证诊断密切相关，其可能成为中医病证诊断的一种新方法。

Literature research and thinking on tongue coating flora and diagnosis of TCM syndromes

Abstract: Human body and microbes depend on and affect each other, so does tongue coating microbes. At present, the research of tongue coating microecology mainly focuses on the tongue coating bacteria. Many factors, such as body constitution and disease, can affect and change tongue coating. In that case, will the tongue coating flora change accordingly? This question has gained attention and been studied. Literature research showed that at present, the research on the diagnosis of tongue coating flora mainly focuses on heart disease, spleen disease and lung disease in TCM. Many studies have shown that dysbacteriosis of tongue coating flora occurred in patients with spleen-associated damp-heat syndrome. The total number of bacteria in tongue coating of the patients was significantly higher than that in healthy people. There was no consistent conclusion about the heart- and lung-associated syndromes. Literature research showed that the changes in tongue coating flora are closely related to the diagnosis of TCM syndromes, which may provide a new method for diagnosis of TCM syndromes.
