Lung biopsy

For such an isolated mass in the lung, it is certainly a benign chance. Lung puncture biopsy can only be performed through its imaging data because CT is an imaging examination and has the characteristic of "same disease, same disease". Presumably, a qualitative diagnosis is not possible. Since CT is suspected to be peripheral pulmonary Ca, fiberoptic bronchoscopy may not be able to reach the lesion, so Ca cells are not easy to detect. Other tests the patient undergoes can only show that the site has not metastasized. To confirm the diagnosis, it is necessary to conduct a percutaneous lung biopsy.

1. The skin is the body, and the hair is the beauty

The fur, including skin, sweat glands, hair and other tissues, is the surface of the body. They rely on the warmth and moisture of Wei Qi and body fluids, and have the functions of defending against exogenous pathogens, regulating body fluid metabolism, regulating body temperature and assisting respiration. The harmony between the lungs and skin and fur refers to the mutual benefit relationship between the lungs and skin and fur. The lungs have two main effects on the skin and fur: 1) The lung qi is released and the defensive qi is distributed to the skin and fur, exerting the defensive qi's function of warming the flesh, filling the skin, nourishing the pores and pores, regulating opening and closing, and defending against invasion by external pathogens; 2) The lung qi is released and the essence is transported to the skin and fur, dispersing the body fluids and part of the essence of food and water upward and outward to the skin and fur, muscles and pores throughout the body to nourish them and make them rosy and lustrous. If the lung essence is deficient and the lung qi is weak, it may cause the defensive surface to be weak, resulting in spontaneous sweating or susceptibility to colds, and the skin and fur may become dry and dull due to the loss of moisture. There are two main effects of fur on the lungs: 1. Fur can disperse lung qi to regulate breathing. The "Inner Canon" calls the sweat pores "Xuanfu" or "qimen", which means that the sweat pores are not only the gateway for the excretion of sweat, but also the site for the exchange of gases inside and outside the body as the lungs disperse and descend. ②When the skin and fur are affected by evil, it can be integrated into the lungs. If the pathogenic cold invades the exterior of the body and the Wei Qi is blocked, symptoms such as chills and fever, headache and body pain, no sweating, and tight pulse may be seen. If accompanied by cough and asthma, it means that the pathogenic cold has damaged the lungs. Therefore, when treating external symptoms, diaphoretics and lung-clearing are often used simultaneously.

2. The orifice is the nose

The nose is the channel for breath to enter and exit, and is directly connected to the lungs, so the nose is called the orifice of the lungs. The nose is the uppermost end of the respiratory tract and is connected to the lungs through the pulmonary system (throat, trachea, etc.). It has the main functions of ventilation and smell. The ventilation and olfactory functions of the nose must rely on the function of lung qi to spread. If the lung qi is unobstructed, the nasal passages will be unobstructed, breathing will be steady, and the sense of smell will be keen; if the lung qi fails to function properly, the nasal passages will be blocked, breathing will be difficult, and the sense of smell will also be poor. Therefore, it is said: "The nose is the organ of the lung" ("Lingshu·Five Views and Five Envoys"); "The lung qi flows through the nose, and when the lungs are harmonious, the nose can sense odors and fragrances" ("Lingshu·Pulse Degree"). In clinical practice, abnormal changes in the nose are often used as one of the bases for diagnosing lung diseases, and the method of dispersing and clearing the lungs is often used to treat symptoms such as nasal congestion, runny nose, and abnormal sense of smell.

3. Worry (sadness) in one’s mind

There are two theories in the Yellow Emperor's Classic of Internal Medicine regarding the lung's will: one says that the lung's will is sadness; the other says that the lung's will is worry. However, when discussing the victory of the five emotions, it is said that "sadness overcomes anger." Although sadness and worry are slightly different, their effects on the physiological activities of the human body are roughly the same. Therefore, worry and sadness belong to the same lung emotion. Sadness and worry are both normal emotional changes or emotional reflections of the human body. They are generated by the lung essence and lung qi, and are manifestations of the physiological functions of the lung essence and lung qi. Excessive sadness or excessive grief are adverse emotional changes, which mainly affect the human body by damaging the lung essence and lung qi, or causing disorders in the movement of lung qi to ascend and descend. "Suwen·Jutonglun" said: "Sadness will deplete the qi." Excessive sadness may cause shortness of breath and other symptoms of insufficient lung qi. On the contrary, when the lung essence and qi are deficient or the lung qi's ascending and descending are disordered, the body's tolerance to external non-benign stimuli decreases, making it easy to produce emotional changes such as sadness and worry.
