In the “Medical Science”, it is pointed out that “choking and diaphragm is a disease that occurs when the throat and chest is blocked by choking and rebellious between the stomach and the mouth, and the phlegm and saliva come out before entering the stomach. “It is also said in the Medical History that “there is a lot of choking and diarrhea in restaurants, especially in those who drink hot wine, because the heat hurts the fluid and makes the pharynx dry and astringent, so food cannot enter”, which accurately points out that the lesion is in the esophagus. By summing up his clinical experience, Dr. Sun believes that although esophageal cancer is in the esophagus, its various symptoms are still mainly due to the spleen and stomach, and it is essentially a spleen and stomach pathology; the reason is that many etiological factors of esophageal cancer, such as the damage caused by substances such as nitrosamines, mold, benzo(a)pyrene and polycyclic aromatic hydroxyl compounds hidden in food, as well as the stimulation of smoking and drinking, hot and spicy food, and the lack of nutrients, vitamins and trace elements, are all essentially related to the damage of the spleen and stomach. In particular, the precancerous state of esophageal cancer and reflux esophagus – barrett’s esophagus is a typical consequence of the loss of harmony between the stomach and the spleen, the upward rebellion of the stomach gas, and the long-term acid reflux and burning corrosion. Therefore, regulating the spleen and stomach is the fundamental treatment for esophageal cancer. To minimize and suppress the chance of esophageal damage caused by acid reflux, the first priority of spleen and stomach regulation should be to strengthen the spleen and raise the level of clearness, followed by strengthening the stomach and eliminating food, harmonizing the stomach and lowering the rebellion. Because the spleen and stomach are the “essence of the latter day”, the “source of biochemistry of qi and blood”, and the place where water and grain are produced, it is always required that “the spleen is not subject to evil during the four seasons” (Jin Han Yao Yao? However, the spleen and stomach are prone to contact with various toxic and irritating substances in food, or substances that damage the function of the spleen and stomach and “suffer from evil”, so the spleen and stomach are prone to suffer damage, resulting in the spleen losing healthy transportation and clearing, and the stomach losing decomposition and descent. As a result, the spleen and stomach are prone to damage, resulting in the spleen losing its ability to move and clear the stomach, and the stomach losing its ability to decompose and descend, which in turn causes the stomach gas to rebel and acid reflux to repeatedly damage the esophagus. Therefore, Sun Shi formula often to Huang Qi as the ruler, strengthen the spleen and clear; to the party ginseng or prince’s ginseng to participate in Atractylodes macrocephala, Poria as the minister, to assist Huang Qi to strengthen the spleen, clear, transport; and Atractylodes macrocephala, Poria also has the function of permeating dampness and phlegm, water and diuretic, can be complemented by Huang Qi to remove the gastric cavity due to the lack of spleen health and the accumulation of phlegm and water-dampness; adjuvant to the red and white peony, biochemical blood, relieve acute pain, but also “in addition to blood paralysis, break It also has the functions of “removing blood paralysis, breaking up hard accumulation” (Shen Nong Ben Cao Jing) and “smoothing the blood vessels, …… removing watery qi” (Famous Doctor’s Book). On this basis, the formula “Jin Mai Dai Ochre Tang” was used to strengthen the stomach and eliminate food, and harmonize and lower stomach qi. The combination of raw malt and hen’s naijin can elevate stomach qi, strengthen the stomach and eliminate food, and remove congestion and stagnation. “It is used in combination with raw malt to lift and lower the pivotal mechanism and regulate the qi. The combination of these three medicines not only accelerates the digestion of stagnant food and descends into the intestines, reducing the time spent in the stomach, but also reduces the chance of upward gastric reflux and acid reflux, which then damages the esophagus. According to the treatise of “Swallowing Acid” and “Noisy”, Sun considered that the patient belonged to the category of “Swallowing Acid” and “Noisy”, and changed his prescription according to the method of “Stagnant Heat in Liver and Stomach” and “Phlegm-Heat Interconnection” respectively. “The formula was divided into Zuo Jin Wan and Xiao Shen Che Tang, and the results were remarkable. According to Sun, esophageal cancer is mainly caused by deficiency of spleen and stomach, loss of harmony and descent of stomach, upward rebellion of stomach gas, reflux of stomach acid, infiltration and corrosion of esophagus, resulting in stagnation of gas, blood stasis, phlegm coagulation and defeat of meat in esophagus, and heat toxicity. Therefore, on the basis of strengthening the spleen and stomach, the anti-cancer and detoxification method is applied, mostly using products that clear heat and detoxify, soften and disperse knots; Sun Shi especially likes to use Shi Mian Pang, which is said in the “Compendium of Materia Medica” as “Shi Mian Pang, the main …… carbuncle”, and its main source of medicine, the “Suzhou native medicinal materials” cloud “This is a good example of the use of this herb for the treatment of choking, phlegm and asthma, and for the treatment of scrofula in Jiangsu. This is also very important for esophageal cancer, which is also a corruption of blood and flesh. In addition, esophageal cancer often infiltrates and grows into the lumen of the tube, resulting in narrowing and obstruction of the esophagus, so patients often feel difficulty in swallowing, and swallowing food or even water can induce severe pain, which greatly affects the quality of life and undermines patients’ confidence in survival. ) and “remove ……Y impasses and flaccid Qi blocks, …… persistent pus and malodorous water” (Kai Bao Ben Cao), and “open the meridians and activate the channels …… pain relief” (“Guangxi Chinese Herbal Medicine”), so it can not only assist Shi Mianpeng in softening and dispersing hard knots, dispelling decay and creating new ones, but also relieving smooth muscle spasm, relieving pain, thus relieving swallowing difficulties and enhancing the patient’s confidence in overcoming tumors. In addition to the above two medicines, Sun Shi also likes to use Tianlong to treat esophageal cancer. Tianlong, also known as Gecko and Shougong, is “salty, cold and slightly poisonous” according to the Compendium of Materia Medica, and is used to treat “blood stagnation, scrofula and scrofula”, and is said to be able to “break blood stagnation and treat swelling and pain” in Sichuan Traditional Chinese Medicine. “In the Medical Recipe Summary, it is even used to treat “carbuncles and sores with great pain” by roasting and powdering Gecko and applying it with oil, indicating that it has the effect of softening hardness and breaking knots, clearing heat and detoxifying, reducing swelling and pain. Modern research shows that Tianlong has a wide range of anti-cancer effects, and Sun Shi believes that it is particularly effective in treating esophageal cancer, so Sun Shi often uses it. In order to remove stasis and create new flesh in esophageal cancer, it is necessary to “remove stasis and create new flesh” and “remove decay and create muscle”. “In order to replace the necrotic cancer tissues with new normal tissues. In this regard, Dr. Sun used the medicine “dahurica dahurica and bupleurum dahurica” to remove toxins and eliminate decay, and “blood residue charcoal and raw pu huang” to remove stasis and create new flesh. Angelica dahurica and Lu Hifang both have the function of extracting poison and ulcerating pus, and the Compendium of Materia Medica has said that Angelica dahurica can cure “sores of knives and arrows”, while Lu Hifang is “a Yangming medicine, which is used in surgery …… to attack poison with poison. “The two can be compared to each other in that they are mainly for detoxification, while Angelica dahurica is mainly for extraction of toxins, and both can be used together to extract toxins and get rid of rot. Modern medicine also proves that both of them have anti-tumor effects. Blood Yu Char and Sheng Pu Huang are both stasis-clearing and hemostatic herbs, which means “removing rotten blood”, while hemostatic herbs can keep the essence of blood from being lost and have the effect of “hiding essence” and “growing flesh”. Master Sun skillfully blends the four herbs together organically to eliminate decay, remove blood stasis, stop bleeding, and grow flesh, thus effectively suppressing tumors, improving symptoms and prolonging life. In addition to the above four herbs, Sun Shi also often used the Chinese name of Andrographis paniculata and turtle nail, in which it is stated in the Compendium of Materia Medica that it can “eliminate carbuncles and swellings and drain pus and blood”, and in the Materia Medica Zaixin that it can “detoxify heat and defeat toxins”, and in the Rizhuazi Materia Medica it is clearly stated that it can treat “It is clear that Andrographis paniculata also has the function of dispelling decay and creating muscle, detoxifying and anti-cancer; turtle nail is stated in Shennong Ben Cao Jing as a main treatment for “polyps, yin erosion, hemorrhoids and malignant flesh”, and in Rihua Zi Ben Cao it is believed to “remove It is also used to remove blood qi, break up y knots and bad blood, eliminate sores and swellings, and to treat blood stasis and intestinal canker. Because both of them are of the A class, heavy in nature and good at walking, they can penetrate deep into the latent place of cancerous toxins and pull them out. 3, dredge the liver to relieve depression Since ancient times, generations of doctors treating “choking diaphragm” evidence always pay attention to dredge the liver to relieve depression, such as Zhang Jinyue has said “choking diaphragm evidence, must be worried about thinking, accumulated labor and depression”, Li Zhongzi also believes that “most of the loss of qi and blood. Therefore, Sun Shi attaches great importance to the role of relieving liver and depression in the treatment of esophageal cancer. As the early symptoms of esophageal cancer are not typical, most of them are already in the middle and late stages when they appear, especially the upper esophageal lesions are difficult to be removed surgically, and a considerable number of patients can only be treated with radiation therapy, which is not effective. To address this situation, in addition to certain drug treatment, Sun’s doctor must also provide appropriate psychological guidance, give appropriate sympathy and comfort to patients, encourage patients to accept treatment with a positive attitude, emphasizing that a relaxed mood is conducive to the prognosis of the disease, so that patients consciously play a subjective initiative, and actively cooperate with drug treatment. In terms of medicine, Dr. Sun prefers to use Prosperity San combined with Er Shu Yu Ling Dan, or add Yu Jin, Xuan Hu, Citron, Buddha’s Hand, Su Mu, and Curcuma to the main formula of tonifying the spleen and stomach, in order to move Qi, invigorate Blood, and clear the liver and relieve depression, achieving better results. Conclusion: The treatment of esophageal cancer is based on the spleen and stomach, with emphasis on regulating the central mechanism of the spleen and stomach, strengthening the spleen and raising the qi, strengthening the stomach and eliminating food, harmonizing the functions of the internal organs, actively preventing acid reflux from aggravating esophageal damage, using anti-cancer and detoxification, eliminating decay and regenerating muscle, eliminating stasis and regenerating new, etc. to effectively relieve symptoms and inhibit tumor growth. He also pays attention to the role of emotion in the process of disease development, and treats the liver to relieve depression, regulate qi, and supplement with psychological guidance to enhance patients’ confidence in fighting cancer. The overall plain and gentle approach of Dr. Sun’s medicine, which has its own characteristics, reflects his profound understanding of the pathogenesis of esophageal cancer and has stood the test of clinical practice.
