Description
Technical Field
The invention relates to a pharmaceutical preparation for treating various malignant tumors, leukemia and chronic bronchitis, a preparation method and a quality control method thereof, belonging to the technical field of medicines.
Background
Cancer has become a common disease in human life, namely the disease of cancer discoloration, and the nightmare is met by all families after the diagnosis is confirmed. It not only can destroy the patient, but also can bring mental, life and economic pressure to the family members and relatives and friends of the patient. Cancer is a group of cells growing rapidly, because the DNA of the cells in vivo is mutated, or the internal environment and external environment are changed, resulting in the sudden growth of the cells and uncontrolled reproduction. Moreover, these cells are invasive and tend to run around the body. Cancer cells are caused by DNA chain gene mutation, and the abnormality of these proteins leads to protein destruction variation and DNA change, and then leads to protein change, the protein is the generated cells, the cells grow fiercely, and the internal environment is changed into the general cachexia state. Cancer can cause pain to patients, and space occupying diseases can cause pressure pain, local lumps and discomfort to patients, and is the most important thing. Cachexia affects absorption normal function, affects all normal functions, leads to loss of life, survivability, and finally death due to cancer. The mortality rate of cancer is generally above 80%, and most children have already metastasized when they are found, so most cancers are very serious. Cancer, a space-occupying lesion, refers to a local mass formed by abnormal proliferation of local tissue cells under the action of various tumorigenic factors, and can be divided into benign tumors and malignant tumors according to the pathological morphology, differentiation maturity, growth mode and degree of harm to patients, wherein benign tumors are generally called tumors, malignant tumors are generally called cancers, cancers are malignant tumors originating from epithelial tissues, sarcomas are malignant tumors originating from mesenchymal tissues, and cancers in popular terms refer to all malignant tumors practically. The types of malignant tumors are also diverse and generally include several aspects: first, malignant tumors derived from epithelial tissues are clinically called true cancers, such as breast cancer, bronchogenic lung cancer, primary liver cancer, pancreatic cancer, colon cancer, and the like. Second, malignant tumors derived from mesenchymal tissues are called sarcomas, such as osteosarcoma, ewing's sarcoma, and the like. Third, malignant tumors derived from embryonic tissues are called blastoma, such as nephroblastoma, neuroblastoma, and the like. Fourth, malignant tumors derived from lymphohematopoietic origin are called malignant lymphoma.
Leukemia is mostly acquired in the acquired days, and most of leukemia is caused by chromosome aberration caused by acquired factors, so that acute leukemia and chronic leukemia appear. The acquired factors include exposure to harmful substances such as benzene, chlorine, pesticides, and chemicals in hair dye, and excessive accumulation of the harmful substances can cause chromosome aberration and tumor diseases. In addition, the contact rays accumulated to a certain dosage can also cause chromosome aberration and the appearance of blood tumor. And repeated inflammatory stimuli, such as persistent viral infections, repeatedly affecting immune function, and in the case of immunodeficiency, leukemia is likely to occur. Some patients are genetically predisposed to the tumor family, i.e., they are predisposed to neoplastic disease throughout the family, including both body and hematological tumors. However, the disease is not immediate after birth, and may be induced by some causes at a certain age.
The number of people suffering from bronchitis, asthma and respiratory diseases, particularly bronchitis, is increasing, most of the people do not pay attention to the disease when the symptoms are mild, and serious consequences are caused. Chronic bronchitis is actually a group of diseases. The symptoms of chronic bronchitis mainly include tracheitis, cough, chronic cough, expectoration, some people are accompanied by asthma, and other diseases may be complicated by the patients. Since this was previously thought to be a disease and now is thought to be a combination of diseases, it is necessary for chronic bronchitis to be closely identified whether it is a complication of other diseases. Chronic bronchitis is often caused by smoking, and also by dust exposure, for example to particular species, and also by problems with bronchial development or bronchiectasis during childhood. This group of diseases is therefore referred to as the manifestation of chronic bronchitis. Chronic bronchitis may be a complex manifestation of three or four diseases in terms of diagnosing a single disease.
The occurrence of diseases is always sudden due to the accelerated pace of life, and the prevention and treatment of the above three diseases are the most important. Therefore, the invention provides a medicinal preparation for treating various malignant tumors, leukemia and chronic bronchitis, a preparation method and a quality control method thereof. The product achieves better treatment effect by various operations such as preparation process, parameter control, quality control and the like, thereby relieving the pain of patients suffering from malignant tumor, leukemia and chronic bronchitis.
