人体肠道细菌是利弊并存的。几十年来,科学家们一直试图了解这些微生物群是如何影响我们的。最近,一项新研究发现,肠道细菌的变化可导致风湿性关节炎的发生。风湿性关节炎是一种不易治愈的疾病,在任何年龄段都会发病,开始阶段患者手部和脚部关节处疼痛、僵硬、肿胀,随着病情的进展,炎症会对患者的骨骼造成破坏,继而伤害内脏器官。过去,科学家们不能确定到底是什么引起了风湿性关节炎,但是他们知道这是一种自身免疫性疾病,这就意味着人体的免疫系统正在攻击自身的组织,而免疫系统正是肠道细菌介入的场所。“多年以来,我们一直怀疑, Human intestinal bacteria are both advantages and disadvantages. For decades, scientists have been trying to understand how these microbiota affect us. Recently, a new study found that changes in gut bacteria can lead to rheumatoid arthritis. Rheumatoid arthritis is an incurable disease that can develop at any age. In the initial stage, pain, stiffness and swelling in the hands and feet of patients are caused by inflammation. As the disease progresses, the inflammation can damage the skeleton of the patient, Then hurt the internal organs. In the past, scientists were not sure exactly what caused rheumatoid arthritis, but they knew it was an autoimmune disease, which means that the body’s immune system is attacking its own tissues, and the immune system is just gut bacteria The place to intervene. ”Over the years, we have always suspected,
