Modern medicine believes that dysphagia after stroke is caused by damage to the brainstem or bilateral cortical brainstem bundles, resulting in paralysis of the muscles related to swallowing, which prevents food from being fully stirred into a food mass and delivered to the pharynx, causing food or liquid to enter the larynx and cause severe choking and coughing, for which there is no effective treatment in Western medicine. The Chinese medicine classifies this disease into the category of “stroke” and “rash”, and the “Ling Shu” says: “People who are suddenly worried about no sound, what road blockage, what gas does not work, so that the sound does not manifest …… pharynx, the water and grain of the road; throat, the reason why the gas up and down; will be loosened, the sound of the door; lips, the sound of the fan; tongue, the sound of the machine; hanging Yongzhi, the sound of the shutdown; fly down the forehead, the division of the gas of the drain; horizontal bone, the spirit of the Qi, the main hair tongue,” explained The mouth, tongue, throat and food swallowing, pronunciation, speech have a close relationship. The “miracle formula” said: “raspy symptoms, tongue raspy can not speak, foot waste not for use”, indicating that the tongue raspy can not make a sound, the tongue can not transfer, and then can not transport food to the pharynx, thus causing swallowing difficulties. According to successive generations of doctors, this evidence is a deficiency of the root and the symptoms, with deficiency of liver and kidney as the root and wind, fire, phlegm and stasis as the symptoms. The deficiency of the lower yuan, Yin does not maintain Yang, deficient Yang floats upward, Qi and blood reverses, phlegm and stagnant blood intertwine with each other to flood the tongue, blocking the orifice of the throat and tongue, the tongue body and throat lose their use, which leads to dysphagia and choking on drinking water. The author believes that the difficulty in swallowing after stroke is due to phlegm and stasis of blood fighting with the orifices, blocking the Yang Qi, and blocking the Qi flow, resulting in the loss of the use of the throat. Difficulty in swallowing is an “orifice disease”, and the orifices are located in the yin area. Only when they are warmed by the body’s clear yang qi can the orifices perform their normal functions. If the Yang Qi is not warmed, the qi will be out of harmony and the nine orifices will not work. “Therefore, the treatment of orifice diseases should be from Yang to Yin. As stated in the “Difficult Classic 67”: “Yin disease moves Yang, Yang disease moves Yin.” The Su Wen Yin Yang Ying Xiang Da Lun points out: “Therefore, those who make good use of needles, draw yang from yin and yin from yang.” For this meaning of “yin and yang”, medical practitioners mostly understand it to mean yin and yang meridians, up and down, left and right, internal organs, and yu and recruitment points, etc., to treat yang or yin meridian diseases or yin meridian diseases with yu points on the back or recruitment points on the abdomen, and to treat diseases of the five organs or six internal organs. In contrast, the author believes that “drawing yang from yin and yin from yang” has two meanings: first, it refers to taking points from the yin position to treat diseases of the yang branch, and taking points from the yang position to treat diseases of the yin branch; second, it refers to the pointer method, which can be used to treat diseases from the yin and draw evil from the yang branch, and from the yang and draw evil from the yin branch. Yang Xuan Cao’s commentary on the “Difficult Classic” reads: “three points into the skin, the heart and lungs, where the yang energy travels” and “five points into the skin, the kidneys and liver, where the yin energy travels”, indicating that the superficial puncture site is the yang part and the deeper puncture site is the yin part. The “Ling Shu Yin and Yang Qing Yu” says: “Therefore, those who stab Yin, stay deep; those who stab Yang, stay shallow and fast.” The pharynx is the place where the foot San Yin meridian passes through, and is a yin point; the Chong Bone point is located above the high bone of the large vertebrae in the neck, and is also located above the route of the Governor’s Vessel, which “supervises all yang” and is the “sea of yang”, and is the master of the yang energy, so it is a yang point. Acupuncture of the Chongbone point in the Yang division is used to treat dysphagia in the Yin division, i.e., to induce Yin from Yang, invigorate Yang energy, expel phlegm and eliminate stasis, and open the orifices, so that Qi and blood can be unblocked and the orifices can be moistened, and swallowing function can be restored. To treat dysphagia after stroke, it is necessary to master the unique acupuncture technique. The author’s clinical observations show that acupuncture at the Chongbone point should be performed from superficial to deep, and after obtaining Qi in the superficial part, pushing it to the deep part, drawing the Yang Qi to the Yin part, pushing the Yang inside, and sparing the Yin part, staying deep, in order to obtain satisfactory results. As the book “The Seventy Difficult Questions” says: “In autumn and winter, the cold must lead to a yang, the first internal needle, shallow and floating, to the heart and lungs, get the qi, pushing the yang inside.” The “difficult scripture” commentary: “to, take also. It is said to use the needle to take its qi also “” push, said to push its qi and into it, as far as the yin part also. This is what the sutra means by “drawing yin from yin to yang and yin from yang”, which explains the method of acupuncture from superficial to profound, “to take yang to harmonize with yin” and “to draw yin from yang”. The acupuncture method of “pushing the yang within from the superficial to the deep” is the key to achieving good results in the treatment of dysphagia. Because it is located adjacent to the central nerve, it has been regarded as a forbidden point for deep acupuncture by doctors for generations. The Chinese Book of Acupuncture states that the acupuncture operation for this point is oblique stabbing 0 5~1 inch. It is mostly used clinically for the treatment of headache, cervical spondylosis, epilepsy, Parkinson’s disease, malaria, bronchial asthma, and intractable eruptions, but has rarely been reported for the treatment of swallowing disorders. Nan Jingzhen et al. used Lianquan, Shanglianquan, Chongbone, Fengchi, Tongli, and Hegu as the main acupuncture points for the treatment of medullary paralysis, but the acupuncture method for Chongbone point is oblique to the root of the tongue 0 3~0 5 inch. The author believes that the acupuncture of the Chongbone point should not only be superficial but also deep, and the depth of acupuncture should be about 70 mm in order to have good therapeutic effect. In this study, the acupuncture depth of 60-75 mm was achieved without adverse reactions, indicating that deep acupuncture of the Chongbone point is safe as long as the technique is performed properly. The results of clinical observation showed that the total effective rate of the deep acupuncture group was 97.0%, which was better than that of the shallow acupuncture group (64.9%) and the traditional acupuncture group (70.0%), indicating that deep acupuncture of the Chongbone point was the most effective treatment for post-stroke dysphagia. The difference between the pre- and post-treatment scores in the superficial acupuncture group was statistically significant only for the decrease in the TCM evaluation scale (P< 0.01), but there was no statistically significant difference between the pre- and post-treatment scores in the Wada drinking test and the standard swallowing function evaluation (both P>0.05), indicating that the efficacy of the superficial acupuncture group was uncertain; the decrease in the scores of the three evaluation scales in the deep acupuncture group and the traditional acupuncture group were statistically significant (both P< 0.01), indicating that both groups had definite efficacy. The difference was statistically significant (P< 0.05, P< 0.01), indicating that deep acupuncture of the bone has the best effect on improving swallowing function after stroke, and is a clinically effective and safe method.
