过去一些病因不明的所谓“非传染性”疾病,近年来对其致病原因已提出许多新发现和新见解,并用许多科学实验和理论加以阐明,使病因日渐明朗。即传染性因子在“非传染性”疾病中的致病作用已日渐被揭露。其实际意义说明一些正常菌群能引起许多慢性疾病,并为消化性溃疡和心血管等疾病找到一条可用药物干预治疗之路。 In the past, some so-called “non-communicable diseases” with unknown etiology have provided many new discoveries and new insights into the causes of etiology in recent years. They have been elucidated with many scientific experiments and theories, making the cause of the disease increasingly clear. That is to say, the pathogenic role of infectious agents in “non-infectious” diseases has been gradually revealed. Its practical significance shows that some normal flora can cause many chronic diseases and find a way for drug intervention in the treatment of peptic ulcer and cardiovascular diseases.
