Beijing, October 31, Xinhua (Xiao Han, Zhang Xinxin, Wang Xi) after autumn, the weather is unpredictable, many people have a cold carelessly, what is the pathogenesis of the cold? How to distinguish different colds? Recently, Liu Xin, associate professor of clinical Chinese medicine department, School of traditional Chinese medicine, Beijing University of traditional Chinese medicine, visited Xinhua “health lecture hall” to talk about the prevention and treatment of cold in autumn with netizens. The following is the content of the interview: the reduction of human immunity easily leads to cold. Host: cold is a common disease with high incidence in our daily life. From the medical point of view, why do people have a cold? What is the pathogenesis of cold? Liu Xin: the term “cold” is a local
term of traditional Chinese medicine, and it is called respiratory tract infection in western medicine. Why does that person have a cold? There are two main reasons: one is external reasons, the other is internal reasons. The external cause is that the external evil invades the human body, so that people get sick, and the internal cause refers to the decline of our normal resistance and immunity. The external cause is the decisive factor, and the internal cause is the main influencing factor. According to traditional Chinese medicine, the external cause is mainly due to six kinds of evil Qi of “wind, cold, heat, dampness and fire”. However, western medicine believes that the main reason is the acute inflammatory reaction caused by virus or bacteria invading human body, that is, the virus or bacteria proliferate, replicate and release in the respiratory tract mucosa, causing the degeneration, necrosis and abscission of epithelial cells, leading to inflammatory changes in the upper respiratory tract. Host: what are the symptoms of a cold? Which behaviors of people easily lead to a cold? Liu Xin: cold symptoms generally include
headache, nasal congestion, runny nose, sneezing, evil wind cold, fever, pulse floating and other main clinical manifestations. Who is easy to catch a cold? The internal cause of cold is an important influencing factor. When people’s daily behavior leads to the decline of healthy qi or resistance, it is easy to lead to a cold. For example, people’s daily life is not regular, often stay up late, diet is irregular and lack of exercise or cold disorder, when it is cold without clothes, when it is hot, we often take cold drinks, and we say excessive fatigue or rain, etc., which lead to low immune capacity of the human body. At this time, with the invasion of exogenous pathogens, it is very easy to lead to a cold. There are different types of colds. Patients need symptomatic treatment. Host: which types of colds? What are the differences between bacterial infection and virus infection? Liu Xin: according to the characteristics of patients’ symptoms, they can be divided into wind cold cold, wind heat cold and heat dampness cold from the perspective of traditional Chinese medicine; if combined with internal factors, it can be divided into six types: Qi deficiency cold, yin deficiency cold and yang deficiency cold. From the perspective of Western medicine, cold is respiratory tract infection. It can be divided into viral upper respiratory tract infection and bacterial upper respiratory tract infection. They are caused by viruses and bacteria respectively. We call them viral infection and bacterial infection for short. The differences between viral infection and bacterial infection are mainly manifested in the following aspects: virus infection is characterized by
obvious group disease, which means that most people will get sick in a short period of time, while bacterial infection is more sporadic; Virus infection is generally manifested as sneezing, runny nose and other symptoms, and these symptoms are more obvious than throat symptoms, while bacterial infection shows tonsillitis, sore throat and other symptoms; simple viral infection generally has no purulent secretion, bacterial infection generally has purulent secretion, purulent sputum is an important evidence; In the process of fever, viral infection fever is called fever, refers to the body temperature is high, but the patient showed a very good mental state. On the contrary, bacterial infection refers to the body temperature up and down, most of them are relaxant fever type, and the overall performance of patients is relatively tired and weak; for viral infection, the use of Andrographis paniculata, Radix Isatidis and other commonly used traditional Chinese medicine can also be improved and alleviated, and for bacterial infection, we need to use the corresponding antibiotics for treatment. The difference between the cold and the cold lies in the difference between a cold and a common cold in TCM. The characteristics of cold pathogen are: cold is Yin evil, easy to hurt Yang Qi; cold stagnation (liquid coagulation block, slow or stagnant flow); cold retraction (sweat pore contraction).
Heat evil belongs to the category of fire evil, fire is Yang evil, its nature is hot; fire is easy to enter the heart and disturb the mind; fire is easy to consume Qi and hurt fluid; fire is easy to generate wind and blood; fire evil is easy to cause sores and carbuncle. Based on the above pathogenic characteristics, the clinical manifestations and treatment of wind cold and wind heat cold are as follows: in terms of aversion to cold and fever; wind cold cold shows severe cold and light fever; wind heat cold shows light cold and heavy fever; in terms of thirst, wind cold cold does not appear thirst; wind heat cold is prone to thirst; wind cold cold is easy to appear thirsty; wind cold cold cold has strong cold and fever; In terms of sweating, the cold with wind cold shows no sweat, while the cold with wind heat shows little or sweat; in terms of sore throat, the cold with wind cold generally does not have sore throat, while the cold with wind heat shows more pain in the throat; in terms of tongue coating, the cold with wind cold shows thin white coating, and the cold with wind heat shows thin yellow coating;
In terms of pulse image, wind cold cold is characterized by floating tight, and wind heat cold shows floating number; in terms of treatment, the treatment of wind cold and cold is to relieve the exterior by pungent and cool; in the aspect of medication, we should use the drugs with pungent and warm relieving the exterior, such as fenghan Ganmao granule, Jingfang granule, Zhengchaihuyin granule, etc., while the treatment of wind heat cold is characterized by pungent and warm relieving exterior
