Local soft tissue infiltration is the slow infiltration of fluid into soft tissue, the infiltration of abnormal cells into human tissue or the appearance of body cells that should not be present under normal circumstances, and the expansion of certain diseased tissue into the surrounding area. So, how should patients prevent the appearance of local soft tissue infiltration symptoms? The main component of the internal environment is plasma, as well as water, protein, inorganic salts, and substances transported by blood (such as oxygen, carbon dioxide, glucose) and non-protein nitrogenous compounds (such as urea, uric acid, creatine, inosine, amino acids, peptides, bilirubin and ammonia, etc.). The internal environment is a medium for the exchange of substances between cells and the outside world, e.g., nutrients that we take in from food and dissolve in the blood plasma (internal environment) are then used by tissue cells. Under normal physiological conditions, the various physical and chemical properties of the internal environment are kept relatively stable, called the homeostasis of the internal environment. This homeostasis of the internal environment is not a fixed static state, but is in a dynamic equilibrium. The physical and chemical properties of the internal environment only change in a small range, for example, body temperature is maintained at about 37℃, plasma pH is maintained at about 7.4, etc. The homeostasis of the internal environment is necessary for the cells to maintain normal physiological functions and for the body to maintain normal life activities, and an imbalance in the homeostasis of the internal environment can lead to diseases. The maintenance of internal environment homeostasis depends on the organs, and the stability of the functional state of internal organs has a key role in the normalization of various regulatory mechanisms of the organism. Due to long-term deviations from our normal lifestyle, various bad habits and habits, especially excessive or improper diet, involve and damage the organs, resulting in an imbalance of the internal environment. The imbalanced internal environment in turn makes some abnormal cells of the organs have the conditions to grow, survive and develop, thus bringing great hidden danger to health. The internal environment of the body is like the soil in which seeds grow. The same seed, grown in different soil, will have different results, and so will the organs of the human body.
