What does ground glass nodule in the lungs mean?

For example, if a chest X-ray or chest CT is performed, ground-glass nodules in the lungs are found. Ground-glass nodules in the lungs are more common in diseases such as inflammation, tuberculosis, tumors, etc. If the nodules are small and the patient has no obvious symptoms such as cough, chest pain, hemoptysis, etc., clinical observation can be performed and chest CT will be reviewed after 3-6 months. If the nodule does not grow, clinical observation can be continued. During the reexamination, if it is found that the nodule has a tendency to grow, or the nodule is relatively large at first, larger than 1cm, or the patient has symptoms such as cough, sputum, chest pain, hemoptysis, etc., he/she needs to go to the hospital for further examination to confirm the diagnosis. , such as bronchoscopy and CT-guided puncture, and if necessary, surgical thoracoscopic resection can be performed to further confirm the diagnosis.

1. The lungs are the respiratory organs of the human body and also the important hematopoietic organs of the human body. They are located in the chest, one on the left and one on the left, covering the heart. The lungs are divided into lobes, two on the left, three on the right, and five at the bottom. Lung Meridian The lung system (referring to the trachea, bronchi, etc.) is connected to the throat and nose, so the throat is called the portal of the lungs, and the nose is the outer orifice of the lungs. The lungs are delicate organs, which summarizes the physiological and pathological characteristics of the lungs. Physiologically, the lungs are clear and delicate. They are full when you breathe in and weak when you breathe out. They are the canopy of the internal organs and the meeting point of the hundreds of meridians. Pathologically, the external evils of the six evils enter through the skin or mouth and nose, and often invade the lungs. It is a disease; diseases of other internal organs also often involve the lungs. Mainly responsible for breathing air: The lungs control the breathing air, which means that the lungs are the place for gas exchange. For example, "Su Wen Yin Yang Ying Xiang Da Lun" says: "The weather is connected to the lungs." Through the respiration of the lungs, clean air is continuously inhaled, turbid air is discharged, the old is expelled and the new is admitted, and gas exchange between the body and the external environment is realized. Maintain the life activities of the human body.

The function of the lungs in controlling breathing is actually a specific manifestation of the spreading and descending effects of lung qi in the process of gas exchange: lung qi is released and turbid air can be exhaled; lung qi is purified and purified. The air can be inhaled. If the spreading and descending effects of lung qi are coordinated and orderly, breathing will be even and smooth. Loss of lung qi or loss of lung qi has clinical manifestations of abnormal breathing, but the clinical manifestations are different. If internal drinking is caused by external factors, blocking the airway and causing loss of lung qi, it will usually result in chest tightness, shortness of breath or asthma; if it is caused by inflammation of the liver fire, which consumes lung yin, the lungs will not be purified, and it will often lead to wheezing, coughing and reversed qi.

2. All blood vessels in the whole body belong to the heart, and heart energy is the basic driving force for blood circulation. The circulation of blood depends on the promotion and regulation of lung qi, that is, lung qi has the function of helping the heart and blood. The lungs regulate the qi of the whole body through breathing movement, thereby promoting blood circulation. Therefore, "Su Wen·Ping Ren Qi Lun" says: "When a person exhales, his pulse moves again, and when he inhales, his pulse moves again." "Nanjing·Yi Nan" says: "When a person exhales, his pulse moves three inches, and when he inhales, his pulse moves again." Three inches. "At the same time, the natural Qi inhaled by the lungs combines with the grain Qi transformed from the water and grain essence transported by the spleen and stomach to generate Zong Qi, and Zong Qi has the function of "penetrating the heart meridians" to promote blood circulation. If the lung qi is abundant, the ancestral qi is strong, and the qi movement is smooth, the blood supply will be normal. If the lung qi is weak or congested and cannot help the heart and blood flow, it may lead to sluggish heart and blood circulation, or even blood stasis, causing palpitations, chest tightness, blue lips and tongue, etc. On the contrary, if the heart qi is weak or the heart yang is weak, the heart and blood cannot run smoothly. Smooth, can also affect the circulation of lung qi, causing cough, asthma and other symptoms.

3. The lungs govern the joints, which means that the lung qi has the function of regulating the breathing of the lungs and the qi, blood and water of the whole body. "Suwen Linglan Secret Theory" says: "The lungs are the official of the prime minister, and they govern the joints." The physiological functions of the lungs in regulating joints are mainly manifested in four aspects: First, regulating respiratory movements: the function of lung qi. The functions of spreading and descending are coordinated to maintain smooth and even breathing, so that gases inside and outside the body can be exchanged normally. The second is to regulate the qi of the whole body: through breathing exercises, regulate the rise and fall of the qi in and out of the whole body, and keep the qi of the whole body smooth. The third is to manage and regulate the circulation of the blood: through the ascending and descending movements of the lungs and Qi, it assists the heart, promotes and regulates the circulation of the blood. The fourth is to manage and regulate body fluid metabolism: through the release and purification of lung qi, the distribution and excretion of body fluids can be managed and regulated. It can be seen that the lungs focus on the joints, which is a high-level summary of the main physiological functions of the lungs.
