The prana, or anus, is the exit of the digestive tract and has the function of excreting feces and gas. Its normal function is the result of the action of many kinds of muscle contractions in the anus, normal nerve conduction, and the coordination between the brain and the command of the defecation center. However, what does Chinese medicine know about the function of the pelvic door? The following combined with the ancient literature to talk about the views. 1, location and name The word “anus” was first seen in the “Nangjing”, the anus is the rear yin, located at the bottom of the torso, the lower mouth of the large intestine, that is, the lower orifice, “Introduction to Medicine” said: “said anus, that its place is like the shape of the car cylinder also”, is to say that its place is similar in shape to the car cylinder. The anus is also known as the pelvic door and the valley. There are two reasons for naming the prana door: it is generally believed that the prana is connected with the meal, rotten food is called prana, and it is also said that the bad food is called prana, and the food and dregs are discharged from the body, “Suwen – Yin and Yang should be like the great theory” said: “clear yang out of the upper orifice, turbid yin out of the lower orifice”, “yin taste out of the lower orifice, yang out of the upper orifice “The reason why the anus is called the prana door is that it means the passage of meal. The Zhuangzi – Heaven’s Way Chapter said: “The ancient people of the dregs of the prana has been Fu? The words food and drink to this, the essence has gone, stop the existence of the dregs of the form, it is called prana door.” The Prana Gate is one of the seven Prana Gates in the “Difficult Classic”, “the lower pole is the Prana Gate”, and the “seven Prana Gates” have an important physiological significance in the human digestive system. Furthermore, the lung and the large intestine are in close proximity to each other, and the lung contains the prana, which is the driving force of the conduction function of the large intestine, and the anus is united with the lung, so it is called the prana gate, which is the gateway of the lung qi downward, so “the lung opens the orifice on the nose and applies it downward to the prana gate”. Wang Bing believes that the nose and the prana gate are respectively outside of heaven and earth, and that if heaven and earth do not lose their order in the body, the nose and the prana gate will always be safe, so inspecting the nose and the prana gate can tell the changes of the body’s qi up and down and in and out. In addition, Zhang Zhenqing and others believe that the “Ghost Gate” in Su Wen – Theory of Tang, Liquid and Mash is the “Prana Gate”, and the “Prana Gate” in Su Wen – Treatise on Five Organs “This is another interpretation of the meaning of the pelvic door. Wang Lizhu, Department of Anorectal Medicine, Affiliated Hospital of Shandong University of Traditional Chinese Medicine 2, opening and closing and self-control The large intestine is the Yang internal organs, is gold, the main fluid, the main collection, the nature of dry, for the transmission of the official, change out of the. Its characteristics, diarrhea and not hidden, real and not satisfied. The pelvic door is the wait for the lung and large intestine, the main travel path, without the function of materialization. The “Thousand Gold Formula – Tongxuan Discernment” says: “The anus is the main travel path, and the lung and large intestine are also waiting for the lung and large intestine, which is called the history of the Tongxian order”. As an important “official”, the pelvic door has an important duty, that is, the main road. During the Qin and Han dynasties, the large pathway for transporting grain and rice was called the rice warehouse road, called the “big line road”, and the prana is the end of the digestive tract, which has a close relationship with the “grain and rice”. Food enters through the mouth and the digestive residue is discharged through the anus, so the prana gate itself is the “lineage”, but it has its own “main” role, i.e. opening and closing. The “opening” is immediate, because the large intestine is “solid but not satisfied”, when the rectum is filled with feces, it is opened fully, timely and effectively, and the Prana Gate opens and completes the “diarrhea but not hidden”, then The dregs can be discharged smoothly and fluently. The six internal organs are smooth, and when the smoothly descending gas in the large intestine reaches the prana gate, the prana gate opens slightly, and then the gas is discharged. “Closed” is a long time, that is, the Prana Gate, which looks like a cylinder-shaped tubular structure, is in a “self-controlled” closed state for a long time, although the “official rank” of the Prana Gate is second to the lungs and large intestine, but it has its own autonomy. It manages itself, that is, self-control, one is to prevent the invasion of foreign objects, and the other is to control the overflow of the contents of the large intestine to the outside. The Prana Gate and the large intestine are connected, and the function of the large intestine “Jin” and “Collect” can strengthen the self-control of the Prana Gate, so the normal long-term closure of the Prana Gate can ensure that the other functions of the internal organs are carried out normally. The Suwen – Five Organs, says: “Water and grain cannot be hidden for a long time”, which shows that the Prana Gate is not just diarrhea without hiding, but has a certain role of hiding, and the temporary hiding of dregs is a good manifestation of the Prana Gate’s self-control, and the short-term “hiding” is If the Prana Gate is not “master”, if the self-control is out of order, if it “hides” too much and does not “hide”, diseases such as constipation and diarrhea or incontinence will occur. The self-control of the prana gate is also an important aspect to ensure the internal storage of true qi, named prana gate, also because the opening and closing of the prana gate is closely related to the role of God, so Zhang Jinyue said: “the large intestine and the lung is the surface, the lung collects the prana and the main, the anus is not guarded, then the qi is trapped and God goes, so it is called prana gate”. If a person is about to die, the prana door cannot control itself, and the “prana” goes from the bottom, which is manifested as the overflow of yagas from the prana door, i.e., commonly known as “prana scattering”. The prana door should also be opened and closed sometimes in an orderly manner, from 5:00 to 7:00 in the morning at the dawn, the heavenly gate is open, the sky is getting brighter, and in the human body, the earthly gate is open, the earthly gate means the prana door, at this time, the large intestine meridian is in order, the prana door is open, and people should defecate normally at the dawn, so that the dregs of the day will be discharged from the body. According to the corresponding relationship between the Ziwu flow of time and the internal organs, Mao time is the period of peak function of the large intestine, the second peak period of the day is the day into the Shen You time, the prana door sense large intestine conduction and open defecation, defecation at the right time, 1 to 2 times a day is the full embodiment of the normal function of the prana door. 3, for the five organs to make the function of the prana gate not only has autonomy, but also passivity and coordination. The Suwen – five viscera, said: “Prana also for the five viscera make”, five viscera heart, liver, spleen, lung and kidney, make, official name, this is related to the five viscera Prana “official name” another way of saying, “make “In terms of “to make”, the prana not only works on the five organs, but also on its own, playing a dominant role. Ming dynasty Zhang Jinyue said: “Although the storage of dregs solid by its diarrhea, and dirty gas lift also depends on the regulation, so for the five organs to make.” Rely on the five organs is to say that the opening and closing of the prana door on the basis of self-control, but also rely on the mastery of the heart, the liver qi to regulate, the spleen qi to lift and transport, the lung qi to declare and descend and the kidney qi to consolidate and regulate gasification, so the opening and closing of the degree, opening and closing sometimes. Therefore, the opening and closing of the prana gate is closely related to the coordination of the yin and yang qi and blood of the five viscera, and if the opening and closing of the prana gate is out of its normal degree, there can be shortness of breath, irritability, stuffiness, abdominal distension, dysesthesia, lumbago, weakness and other functions of the five viscera. The dysfunctional manifestations of the five organs may occur. Zhang Libei et al. explained that the Lung Qi descends the Prana Gate, the Spleen Qi ascends the Prana Gate, the Liver Qi unclogs the Prana Gate, the Kidney Qi takes in the Prana Gate, and the Heart Spirit dominates the Prana Gate, so Prana Gate diseases can be treated from the Five Viscera, and Five Viscera diseases can also be treated from the Prana Gate. Lu Ming flexibly applied the principle of “the five viscera” to regulate the functions of the internal organs by warming the spleen and kidneys, draining the liver and Qi, supporting the spleen and suppressing the stomach, relieving the surface and harmonizing the interior to improve the abnormal anal excretion, and changing the anal excretion by clearing the heart, warming the interior, removing heat, resolving blood stasis, and facilitating the bowel movement to eliminate internal diseases and evils. According to Ma S, the Prana Gate is “the messenger of the six internal organs and also the messenger of the five viscera”. When there is actual heat, blockage and upward rebellion in the internal diseases, opening the Prana Gate and opening the stool can achieve a therapeutic breakthrough, not only for the anal lesions. Therefore, “the prana gate is also the cause of the five internal organs” in the Neijing fully reflects the basic features and theoretical core of the holistic concept of Chinese medicine, and provides the theoretical basis for clinical evidence-based treatment. 4, disease and prevention Sun Simiao “Thousand Gold Formula” said: “If the organs are injured by heat, the anus is closed, the large line does not pass, or swelling and shrinkage into the sores. If the internal organs are injured by cold, the anus is open, the large line hole diarrhea, anal protrusion, a long time is into. Heat is through the, cold is complementary.” Dysfunction of the prana can occur this disease and other diseases. Disorders of yin and yang, deficiency of internal organs, internal injury of emotion and will, poor operation of qi and blood, combination of dampness, heat, wind and dryness, stasis of blood and turbidity of qi injecting down into the prana gate and prana gate diseases, such as prolapse, stenosis, hemorrhoids, anal canker, anal leakage, cleft anal hemorrhoids and other diseases of the anal area. If the prana gate is not self-controlled and its opening and closing are disordered, other diseases may occur, such as constipation due to deficiency of fluid and dryness of the intestines, and constipation due to weakness of opening and closing; diarrhea due to inability of the prana gate to close due to downward injection of damp heat or deficiency of qi. The treatment of pranic disease cannot only focus on the large intestine and pranic disease, but can also start from the five viscera to identify and treat, such as constipation, treat from the lung, lift the pot to uncover the lid to pass the stool. For inflammatory external hemorrhoids that are edematous, use mahagang and shigang soup to promote the lung and reduce swelling, and the edematous hemorrhoid nucleus will soon atrophy. How to make the prandial less or not to develop? The emphasis is on conditioning and maintenance. The lung is the lung and large intestine of the wait, the lung collects the prana, “Shuo Wen Jie Zi” said: “prana, Yin Shen also. From the ghost white sound. Pu hundred cut.” The prana is the yin god, the spirit that exists attached to the human body, and The Spiritual Pillar – Ben Shen says: “and the one who goes in and out of the essence is called the prana.” When sleeping at night, the prana is in charge, and the “Spiritual Pivot – This God” also says: “joy and happiness without extreme will hurt the prana”, and there are idioms such as “soul lost and fallen”, “soul flying and scattered”, “three souls and seven spirits”, which shows the importance of the prana, and the way of nourishing the prana is all in regulating the breath, so regulating the breath and lifting the anus is an effective way to store the prana. Taoist Laozi believes that “the god of the valley does not die, is the root of heaven and earth”, the valley road prana door is the root of heaven and earth, take the initiative to strengthen the anal function exercise, regular conditioning summary mention the valley road and irregular valley road often mention can strengthen the five organs and prolong life. The health care of the pranic door is very important to prevent the occurrence of diseases, and should reflect the idea of “treating the disease before it happens”. The treatment method of the “Fifty-two Diseases Formula” for “people who cannot get out of the state (prolapse)” is to hang the person upside down and splash his heart and abdomen with cold water, then the prolapse will be carried out. The author’s clinical experience, the prana door open and close health care can be used cold and hot water cleaning sitz bath method, because the turbid Yin out of the lower orifice, the prana door is the end of Yin fire, defecation, the prana door performance for the fire hot image, after the bowel movement with cold water cleaning, a short time, can play the role of water and fire, not only can wash the prana door of fecal traces, to avoid the friction of the toilet paper, but also help the prana door after the stool lift and solid shrinkage; not defecation, the prana door of a long time self-control, there are Different degrees of Yin deficiency and fatigue, before going to bed with warm water bath 10min ~ 30min, can play the role of warm yang to fill the deficiency, help Yin and Yang reconciliation, the prevention and treatment of pranic disease has a very good effect.
