Dietetic gangrene

　　The cause of leprosy is mainly due to an unhealthy spleen and kidney yang deficiency, and external exposure to cold and frost, with the invasion of pathogenic cold and dampness. An unhealthy spleen cannot transform sufficiently, leading to deficiency of Qi and blood. Internally, it cannot nourish the zang-fu organs; externally, it cannot nourish the limbs. Insufficient spleen and kidney yang cannot warm the limbs, and if they are further attacked by cold and dampness, Qi and blood may become stagnant, the meridians and collaterals may be blocked, and pain will occur when there is no通畅. The Qi and blood in the limbs are not sufficient, and the skin and flesh will become dry and necrotic and fall off. If the cold pathogen is retained for a long time, it may transform into heat, leading to damp-heat infiltration, and the affected toes (fingers) may become red, swollen, and ulcerated. Heat may injure Yin, leading to deficiency of Yin and blood over time, causing the limbs to lose nourishment and become withered and atrophic. The occurrence of leprosy is rooted in the deficiency of the spleen and kidney, with external injury of cold and dampness as the superficial manifestation, and Qi and blood stagnation and meridian blockage as the main pathological mechanism.

　　Leprosy is a chronic peripheral vascular disease characterized by necrosis at the ends of the limbs and shedding of toe (finger) joints in severe cases. It has ischemic pathological changes in nerve, muscle, and skeletal tissues. If local infection occurs, systemic toxic symptoms such as fever, aversion to cold, and irritability may appear. The ischemia of the limb ends is more severe, leading to ulcers or gangrene. Most cases are dry gangrene, and if secondary infection occurs, it may present as wet gangrene.

　　1. Sepsis

　　Sepsis refers to the systemic toxic symptoms caused by the entry of toxins produced by bacteria or other toxins into the blood circulation.

　　2. Dry gangrene

　　Dry gangrene is unrelated to bacterial infection. When blood flow to a certain tissue is blocked or reduced, dry gangrene occurs. When muscle tissue becomes necrotic, it is extremely painful. Once the muscle dies, it becomes numb and gradually turns black. A visible line can be seen between the necrotic tissue and the living tissue.

　　3. Wet gangrene

　　Infectious 'wet' gangrene is a toxin produced by the bacterium Clostridium botulinum, which breeds on necrotic muscle tissue, causing the death of muscle and upper skin in a certain area.

　　To prevent gangrene, doctors sometimes inevitably have to amputate part of the limb, which will also be one of the serious complications of the disease.

　　Leprosy is a chronic disease characterized by ischemic necrosis of the limb ends, which may even lead to the shedding of toe (finger) joints. It is equivalent to thromboangiitis obliterans in Western medicine. Its clinical characteristics are that it often occurs at the ends of the limbs, with the lower limbs being more common. Initially, the toes (fingers) may feel cold, pale, numb, and have intermittent limpness. Then, the pain becomes severe, and over time, the affected toes (fingers) may become necrotic and turn black, even shedding toe (finger) joints. The onset of the disease is slow, with the initial symptoms of the affected toes being white and cold, numb and painful, and over time, the affected toes may become like cooked red dates, with pain as if on fire. Gradually, the color changes from red to dark and black, and the toes often fall off spontaneously and may affect all five toes. The wound is extremely difficult to heal, and the appearance of new flesh protecting the bone after the limb joint is shed is a sign of improvement.

　　Avoiding trauma, prohibiting smoking, eating less spicy, roasted, and strong alcoholic beverages, etc. are the main preventive measures for gangrene. When working outdoors in winter, pay attention to keeping warm, and the shoes and socks should be loose and comfortable. Soak both feet in warm water every day. Limb exercise can promote collateral circulation in the affected limb. The method is for the patient to lie on their back, elevate the lower limbs for 20-30 minutes, then lower the feet to the edge of the bed for 4-5 minutes, at the same time, move the feet and toes up, down, in, and out 10 times, then place the lower limbs flat for 4-5 minutes, and exercise 3 times a day. It is not advisable to exercise too much when there is gangrene infection, and one should rest quietly.

      When diagnosing gangrene, in addition to relying on its clinical manifestations, it is also necessary to rely on auxiliary examinations. The main examinations for this disease include traditional Chinese medicine diagnosis, urinalysis, skin color, blood sugar, blood pressure, urine routine, blood routine, and stool routine.

　　In addition to surgical therapy and traditional Chinese medicine treatment for gangrene, the following dietary therapy can also effectively improve the symptoms of gangrene.

　　1. Euonymus root and pork trotter soup:180 grams of euonymus root, one pork trotter, boil in water for 3-4 hours, eat the meat and drink the soup, take it in three doses a day, and take it continuously for 1-3 months.

　　2. Red bean and date soup:60 grams of red bean, 5 dates, boil the beans until they are soft, add an appropriate amount of brown sugar, take the juice as tea, one dose per day.

　　The surgical treatment method for gangrene is for limbs that have failed to respond to treatment. After the necrotic tissue and healthy tissue are clearly demarcated and the proximal inflammation is controlled, necrotic tissue removal can be performed, and the bone断面 should be slightly shorter than the soft tissue断面. When the necrotic tissue and normal tissue are clearly demarcated, and the proximal inflammation is controlled, blood supply improved, a near demarcation incision can be taken, and toe (finger) excision and suture or half-foot excision and suture can be performed. When the necrosis extends to the back of the foot and the ankle, below-knee amputation can be performed; when the necrosis extends above the ankle, knee joint amputation can be performed. When the ulcer surface is large, skin grafting can be performed after the wound is clean and blood supply is improved..
