Malignant effusion includes malignant thoracic ascites, malignant pericardial effusion, malignant hydrocephalus, etc. For hemoperitoneum hemagglutinin has certain efficacy, but for celiac disease there is no good method in both Chinese and Western medicine. For malignant effusion, traditional medicine ancient and modern doctors have evolved many treatments, or from the lung, or from the spleen, or from the kidney, or from the heart, or from the liver, and it is difficult to find the origin of the latter, not knowing that the Nei Jing points out that “all diseases, clear and cold, all belong to cold” “all turn against the hostile, cloudy water, all belong to heat “I treat most malignant effusions as cold, and see that yellowish malignant effusions can be treated from cold, and the effect of internal and external acupuncture and moxibustion for malignant effusions is very satisfactory. Theoretically, acupuncture and moxibustion on the basis of the basic selection of acupuncture points plus the original points of Sanjiao and Bile meridians may have a better effect. The third affiliated hospital of Beijing University of Traditional Chinese Medicine, acupuncture and minimally invasive oncology department Jin Chang 1, external application of traditional Chinese medicine is generally available for external treatment of tumors with the addition of the treatment formula of yin, water decoction and thick cream external application of thoracoabdominal fluid, which has a certain effect. The effect of external application of Chinese medicine is not as fast as that of acupuncture. 2, acupuncture treatment (1) acupuncture thoracic fluid acupuncture Yunmen, period door, Zhangmen, Jingmen, warm acupuncture Guan Yuan, Zhongji, Guilai, water channel. For ascites, acupuncture is performed on Neiguan, Shui Shui, Zhonghua, Tianshu, 3 inches next to the umbilicus, Qihai, Guan Yuan, Zhongji, Guilai, Dao Shui, Shimen, Yinlingquan, Sanyinjiao and Yangchi. Add relevant points according to the primary focus and cause of ascites; for example, add Neiguan, Sanyinjiao, and Blood Sea for liver cancer ascites; Qihai and Guangyuan for intestinal cancer and ovarian cancer; Neiguan and Taichong for qi stagnation; Sanyinjiao and Blood Sea for blood stasis. (2) Moxibustion Pericardial effusion insists on using moxibustion Xuli, once a day for one hour, which has good effect. (3) Medicinal moxibustion for hydrocephalus is used for Baihui and Shen Que for ascites, once a day for one hour, with satisfactory results. Drug composition: Hosin, Sichuan pepper eye, cinnamon stick, raw astragalus, longan, vinegar Gansui, grinded into fine powder. Deeper thought: Why do pericardial effusion and pleural fluid grow in a closed cavity (within the pericardium and within the dirty wall layer of the pleura), while ascites and hydrocephalus are closely enclosed with organs and brain tissue in the abdominal cavity? Why is it that ascites tends to recur even after it disappears, but pleural fluid does not? This is a question that the world has not considered. In detail it is very simple, ascites and hydrocephalus are closely related to dampness, dampness is sticky, diffuse and downward tending, so it is connected to the surrounding tissues, while pleural fluid and pericardial fluid are caused by water drink on a certain part of the ling, water drink can easily disappear by warming Yang and transforming water. Therefore, the acupuncture points for the treatment of thoracic fluid and ascites are different, and the treatment of ascites should pay attention to strengthening the spleen, regulating qi and resolving dampness, while the treatment of thoracic fluid should warm the kidney and resolve qi. If phlegm-dampness injures the lung, it often manifests as interstitial lung lesions, emphysema, radiation pneumonia, etc. I think this is due to the long-term infiltration of phlegm-dampness into the alveoli resulting in alveolar elasticity weakening and wheezing, which is to pay attention to the selection of points such as Tiantu, Juqui, Tanzhong, Phlegm Asthma, Zhongfu, Taichong, Taixi, Taiyuan, Yangchi, Neiguan, Quze, Shouze, Qihai, Guangyuan, Shimen, etc. to tonify the kidney and benefit the lung and resolve phlegm; if water-drink overtakes the lung, it manifests as pulmonary edema. Water drink in the abdomen can manifest as simple local edema, such as perihepatic ascites, peri-spleen ascites; in the intestines as watery diarrhea or water-heat mutual inability to pass stools and urine. From here, we can see the difference between water and dampness causing disease. In the book of Acupuncture and Moxibustion, “Water, skin distension, bulging, intestinal mushroom, stone obstruction”, it is said that “can abdominal distension and bulging be pricked? I said: first stab the blood channels of the abdomen, after adjusting its meridians, also stab to remove its blood vessels. The “edema, the human middle is full, the lip is reversed is dead, the water ditch is the main. Edema, large navel flat, moxibustion umbilicus, no reason not to cure. Edema, water qi line in the skin, Yinjiao main. Edema, large abdomen, water swelling, water qi line in the skin, Shi Men is the main. Shi Shui, pain leads to swelling under the duress, head dizziness and pain, the body is all hot, Guan Yuan is the main. Zhen cold, large abdominal stone water, four full of the main. Shi Shui, stabbing Qi Chong. Shi Shui, Zhang Men and Rangu, main. Shi Shui, Tian Quan is the mainstay. The abdomen is full of qi, the abdomen is distended and rebellious, <千金> as “water distension and rebellion”. It is not possible to lie down, Yinlingquan is the mainstay. Edema retention, chest full, stabbing the trapped valley, bleeding immediately self. Edema and swelling, skin swelling, Sanli is the mainstay. There is a large hernia accumulation in the cell, with Yin leading to pain, bitter chung drainage up and down out, tonic shouze, Taixi, hand Yangming inch mouth are tonic”. Available for reference.
