    The main treatment of cancer At present, cancer treatment is mainly based on "operation, chemotherapy and radiotherapy" Operation is the first choice for cancer treatment Unfortunately, many patients have found cancer at an advanced stage and have lost the opportunity of surgery They can only choose radiotherapy and chemotherapy However, chemotherapy has a lot of toxic and side effects Many patients will suffer from different side effects after operation Suffering
    Side effects of radiotherapy and chemotherapy Decreased immune function: chemotherapy drugs can lead to the decrease of white blood cells, damage the immune system of patients, and lead to the defect or decline of immune function Physical weakness: chemotherapy patients will appear fatigue, mental weakness, sweating, drowsiness and other adverse reactions Inflammatory reaction: fever, dizziness, headache, dry mouth, sore mouth and tongue, etc May also cause phlebitis, cystitis and other inflammatory diseases It can also cause hair loss Organ toxicity: some chemotherapy drugs can cause renal function, heart function, liver function damage Lead to organ failure and damage Dyspepsia: many chemotherapy drugs can cause loss of appetite, decreased diet, nausea, vomiting, abdominal distention, abdominal pain, diarrhea or constipation by stimulating gastrointestinal mucosa Half of the patients died because of the side effects of radiotherapy and chemotherapy Nowadays, the main treatment for cancer patients is radiotherapy and chemotherapy But not everyone can afford the side effects Half of the patients died because of the damage of many organs or the sharp decline of resistance caused by radiotherapy and chemotherapy This also makes the majority of doctors and patients realize that when using radiotherapy and chemotherapy to treat cancer, we should also take a series of effective measures to relieve the side effects of chemotherapy on human body, so as to prolong the life of patients
    How to alleviate the side effects of radiotherapy and chemotherapy In order to reduce the side effects of radiotherapy and chemotherapy, many people have used a variety of traditional Chinese medicine, health products and even food therapy The following is a summary of the effective mitigation methods proposed by many scientific experts 1、 Combined with professional means of anti radiotherapy and chemotherapy 1) Change the route of administration In some tumors, in particular cases, intrathoracic and intraperitoneal administration, arterial infusion, intratumoral injection, limb cardiopulmonary bypass infusion or "half body chemotherapy" to block the abdominal aorta can be used to improve the local drug concentration of the tumor, reduce the blood concentration of the systemic circulation system, and reduce the systemic toxicity of chemotherapy drugs 2) Component transfusion In cancer chemotherapy, hematologic toxic leucopenia and thrombocytopenia are the most common, which can lead to infection and bleeding in severe cases If necessary, transfusion of concentrated leucocyte or platelet component blood can prevent and treat serious infection and bleeding 3) Bone marrow transplantation The chemotherapy of solid tumor of peripheral blood stem cell transplantation mostly adopts autogenous bone alkali transplantation and autogenous peripheral blood stem cell transplantation It is to extract the bone marrow of the patient before intensive chemotherapy for cryopreservation or collect the peripheral blood of the patient after mobilization for cryopreservation, and then return it to oil after chemotherapy In this way, part of the hematopoietic stem cells can be protected from the damage of anti-cancer drugs, which is conducive to the hematopoietic function The recovery of energy 2、 Scientific and reasonable diet People with radiotherapy and chemotherapy should eat more foods rich in protein, iron and vitamins, such as fish and lean meat In addition, animal liver, jujube, longan, donkey hide gelatin, fresh fruits and vegetables are also beneficial to patients Patients with anorexia, dyspepsia and diarrhea can be supplemented by spleen strengthening and stomach nourishing foods, such as job's tears, white lentils, dates, etc.; at the same time, it is necessary to pay attention to the change of the patient's recipes, change the cooking methods and types of dishes regularly, pay attention to the deployment of color, fragrance and taste, so as to stimulate the patients' appetite, and follow some principles in the diet Dietary principles: 1) Eat less and eat more Avoid empty stomach or abdominal distention 2) Take a moderate rest after dinner, but don't lie on your back 3) Eating dry food before and after getting up and before exercise, such as biscuits or toast, can inhibit nausea; do not eat immediately after exercise 4) Eating should be avoided within 2 hours before receiving radiation or chemotherapy to prevent vomiting 5) If the patient is not ill to the state of bedridden, before eating, the patient can be asked to do appropriate exercise, and then eat some small amount of appetizers, such as dandruff, hawthorn tablets, and finally eat the main food Appropriate exercise will promote the metabolism of new and old, promote gastrointestinal peristalsis and increase appetite 3、 Proper exercise The continuation of life is more about movement While actively cooperating with the treatment, we should pay attention to external nutrition supplement, insist on exercise and do some aerobic exercises, such as yoga, jogging, Taiji, etc Physical exercise is conducive to the growth of human bones and muscles, the enhancement of cardiopulmonary function, the improvement of the functional status of the blood circulation system, respiratory system and digestive system, the growth and development of human body, the improvement of disease resistance, the enhancement of the adaptability of the body, and the self adjustment of the body to nausea and vomiting You can also engage in minor activities, such as listening to music, watching TV or talking to others, to distract yourself from the disease 4、 Keep yourself in a good mood Cancer patients are often worried about their own conditions, fear, anxiety, this time will stimulate the nerve center of the human body, produce anorexia, do not want to eat At this time, we should guide the patients more, let them have a relaxed attitude to treat the disease, ensure the normal supply of three meals a meal, and try to keep the dining environment clean and comfortable 5、 Take nutrition rich in high protein and regulating immunity Most of the anti-tumor chemotherapy drugs have immunosuppressive effect, so the patients receiving radiotherapy and chemotherapy often have the characteristics of low white blood cell and low immunity Radiotherapy and chemotherapy patients may not be as energetic and appetite as normal people, so the food we prepare for patients must have high nutritional value, which is conducive to digestion and absorption However, conventional high protein food and nutrition products are absorbed by human body, but it is difficult for patients to directly digest and absorb macromolecular protein, which must be broken down into small molecules, and then be absorbed by human body In the past, science believed that human body absorbed protein mainly in the form of amino acids In recent ten years, scientific research has found that human body absorbs proteins mainly in the form of small peptides This great discovery has changed people's new cognition of protein absorption form Therefore, the absorption and utilization of protein can be improved directly by the form of small peptide Peptide is an active substance between amino acid and protein All the active substances in human body are in the form of peptides Peptide is an important physiological regulator of human body There are hundreds of peptides in human body Peptide relates to hormone, nerve, cell growth and reproduction of human body It can comprehensively regulate human physiological function, enhance and play human physiological activity Peptide has an important biological function, which is very important for human cell activity, functional activity and life Peptide can synthesize cells and regulate the function of cells; peptide, as a neurotransmitter, transmits information; peptide, as a means of transport, transports various nutrients, vitamins, calcium and trace elements to human cells, organs and tissues Significance of Sanjiu small molecule peptide in radiotherapy and chemotherapy of tumor The purity of Sanjiu small molecular peptide is as high as 96% It contains 20 kinds of amino acids, 8 kinds of human essential amino acids, and the content of essential amino acids is as high as 39%; the content of unsaturated fatty acids is as high as 70%; the content of minerals such as calcium, zinc and selenium is rich As a kind of exogenous small peptide, it is a small peptide obtained by artificial machine and equipment, which simulates the degradation of human protein It has two main functions of immune regulation and anti radiation, and is suitable for slowing down the toxic and side effects of various cancer radiotherapy and chemotherapy For example, colon cancer, pancreatic cancer, breast cancer, esophageal cancer, lipoma, lung cancer, bladder cancer, pre breast cancer, liver cancer, kidney disease, lung disease, liver disease and other diseases Regulate immunity: stimulate the immune system of the body to produce specific immune response; stimulate cells to produce antibodies, but also stimulate immune cells to produce immunoglobulins, improve human immunity Improve the essence and spirit: no need to digest and absorb directly, no burden on the stomach and intestines, quickly synthesize protein and other important components, restore normal physiological activities, and improve mental state Repair gastrointestinal tract and increase appetite: repair gastrointestinal function, strengthen gastrointestinal peristalsis, increase appetite and avoid nausea and vomiting Repair damaged cell tissue: quickly fuse with cell membrane, and then repair damaged cells, so as to repair tissues and organs Improve the level of white blood cells: promote the proliferation of white blood cells, significantly increase the content of white blood cells, so as to improve immunity and disease resistance Anti cancer cells: stimulate macrophages and phagocytes to phagocytize cancer cells Prevention of cancer cell proliferation and metastasis: promote cell adhesion and hinder its value-added function, effectively prevent and control cancer cells, prevent cell tissue aging, and prevent the growth and metastasis of malignant tumors Destroy the environment for the growth of cancer cells, and control the growth and proliferation of cancer cells
    Why does tonifying peptide choose small molecule peptide? Because of its small molecular weight, small peptide can be absorbed in gastrointestinal tract without digestion or a little digestion, which can significantly reduce the digestive burden of gastrointestinal tract The peptide with large molecular weight can not be directly absorbed after entering the human body, but also needs transformation, so the effect is not as good as the peptide with small molecular weight Characteristics of small molecular peptides Directly involved in the metabolism of blood cells, brain and nerve cells, muscle cells, reproductive cells, endocrine cells, skin cells, and involved in cell growth, development, physiological function and division and proliferation of various links Advantages of small molecular peptide The absorption, transformation and utilization of small molecular peptides are efficient, complete and thorough It is an important manifestation of the biological activity of small molecular peptides that enter the cells directly in the form of prototypes Small molecular peptides participate in the synthesis of enzyme, stimulate the activity of enzyme, strengthen the function of enzyme and maintain the stability of enzyme Small peptide improves the permeability of metabolizing membrane It can effectively absorb nutrients, excrete toxins, and prevent the invasion of pathogens By controlling the transcription of DNA, small peptide can maintain the inheritance of cell dominant information Small peptides produce special physiological effects through the synthesis of specific proteins Small molecular peptides have dual effects on cells, which can not only supplement nutritional needs to repair defects, but also improve functional status At the same time, it has dual responsibilities of carrying tools and materials Absorption of small peptide Small molecular weight, no digestion, direct absorption The absorption is fast, and the oral dose is like an injection The small peptide has the characteristics of 100% absorption by human body Absorbed in a complete form Small peptides are preferentially absorbed by human body.
