微循环是人体最小的功能单位。微循环障碍是指发生在微循环水平上的血管和血流的形态与功能的紊乱,包括由此引起的一系列缺血、缺氧性细胞病变。当今世界人口日趋老化,我国60岁以上老人也接近10％,这已已引起了疾病和死因结构的变化。绝大多数老年病学家同意老化不是单一原因,目前有多种解释老化的理论,在老化基础上发生的多种病症虽各有特定原因,但临床实践、等证实,改善微循环在老年病防治中具有较普遍的意义。一、微循环和微循环障碍近几年,微循环研究正处于“复兴时期”。微循环直接参与细胞、组织间的物质交换。广义的微循环应包括三个系统中的体液循环,即微血管(血液微循环)、毛细淋巴管(淋巴微循环)、组织导管(超微循环系)。不同组织器官各有特自的微血管构形,组成各自的微循环单位,以保证正常的灌流(Perfusion),完成特定的功能。
Microcirculation is the smallest functional unit of the body. Microcirculation disorders refer to the morphological and functional disorders of blood vessels and bloodstreams that occur at the level of microcirculation, including the resulting series of ischemic and anoxic cell diseases. As the world’s population ages, the number of elderly people over the age of 60 in China is also approaching 10%, which has already caused a change in the structure of the disease and cause of death. The vast majority of geriatricians agree that aging is not the sole cause, there are a variety of theories to explain the aging, a variety of conditions on the basis of aging, although each have specific reasons, but clinical practice, confirmed that the improvement of microcirculation in geriatric Prevention has a more general significance. First, microcirculation and microcirculation disorders In recent years, microcirculation research is in the “renaissance period.” Microcirculation directly involved in the exchange of material between tissues and tissues. The generalized microcirculation should include the circulation of the body fluids in three systems: microvascular (blood microcirculation), lymphatic capillaries (lymphatic microcirculation), and tissue duct (microcirculation). Different tissues and organs have their own micro-vascular configuration, the formation of their own microcirculation units, in order to ensure normal perfusion (Perfusion), to complete a specific function.
