The social burden of somatic symptom disorder is increasing, and due to its complexity and heterogeneity, the pathological mechanism is not well understood, and there are currently no specific drugs or **. According to the analysis of the syndrome differentiation of will and intention suitable for mental and psychological behavioral diseases, the basic pathogenesis is that the soul is hyperactive and weak, the will is biased, and the spirit is weak and weak. In the early stage, the body is not damaged, the soul is weak and the will is shaken, and the soul is strong and the will is reconciledIn the middle and late stages, it can be seen that the liver is depressed and the spleen is deficient, the soul is not harmonious, or the heart and kidney are not connected, the will is not controlled, or the phlegm and fire are abundant, the mind is restless, or the long-term illness does not heal, the liver and kidney are insufficient, the spirit is weak and the spirit is weak. 
Somatic symptom disorder (SSD) was first introduced in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to replace the original "somatic form disorder (SFD)" diagnosis. DSM-5 no longer requires that "symptoms are not explained by medical evidence", but adds the criteria of positive mental and behavioral characteristics, emphasizing positive symptoms and signs (painful physical symptoms) and thoughts, emotions and behaviors that respond abnormally to these symptoms or signs, rather than the lack of medical evidence to explain physical symptoms, which is summarized as the three core points of physical symptoms, high anxiety or excessive worry, and the duration of the disease greater than 6 months. According to the American Psychiatric Association, the incidence of SSD is 5% to 7%, which is the most common disease in primary care settings, with a male-to-female ratio of 1 10. Such patients generally repeatedly seek help from various clinical departments, and rarely go to psychiatric departments or mental health centers, which puts forward higher requirements for the identification, diagnosis and standardization of primary medical institutions**. SSD does not have an exclusive disease name in the TCM system, and according to its clinical manifestations, it is mostly classified into the category of depression, irritability, dolphin, palpitations, madness, insomnia and other mental diseases. "The Yellow Emperor's Neijing" laid the theoretical foundation for the differentiation of will, and the differentiation of will-will disease and physical disease began to take shape"Shennong's Materia Medica", "Famous Doctors' Records", "Qianjin Yifang" and other works laid the foundation of the Zhiyi, spiritual, soul, and medicinal treatment system;From the Northern and Southern Dynasties to the Tang and Song dynasties, the theory became more and more perfect and widely used in clinical practiceHowever, after the fall of the gold yuan, the dialectic of will was gradually lost. Through the study of classics and clinical practice, Yan Zhaojun's team repaired and constructed a theoretical system of aspiration syndrome differentiation suitable for mental and psychological behavioral diseases. The main research content of the zhiyi syndrome differentiation is the spiritual soul of the will, which is suitable for mental and psychological behavioral diseases. Based on the theory of will-meaning syndrome differentiation, the author analyzes the syndrome types, pathological stages and syndrome differentiation of SSD**.
1. Distinguish the genus of disease syndrome
The pathogenesis of SSD is still inconclusive, and the academic community believes that it may be related to neurological factors, environmental factors, psychological characteristics, etc. The identification and diagnosis of SSD does not emphasize whether the somatic symptoms themselves can be explained by organic or functional physical diseases, but emphasizes the characteristics, patterns and consequences of individual cognitive, emotional, behavioral and other mental symptoms when the body has symptoms. Patients present with high levels of anxiety or excessive concern that do not correspond to the severity of the condition, have persistent thoughts, or spend a lot of time and energy seeking medical advice and information. Obviously, psychiatric symptoms are the core manifestation of SSD. 
Due to the complexity and heterogeneity of this disease, there is no standardized diagnosis and treatment system. At present, Western medicine** is mainly antidepressants, or atypical antipsychotic drugs** in combination. In addition to drugs**, supportive psychological**, cognitive-behavior**, biofeedback**, Morita**, and repetitive transcranial magnetic stimulation have also been reported to be applied and effective. If you do not take active action**, in addition to the aggravation of your own condition, it may also lead to the aggravation of your comorbid physical illness or mental disorder. From the diagnostic criteria, core symptoms, methods and outcomes of the disease, it can be concluded that the occurrence and development of SSD is mainly responsible for the disharmony between human life and society as a whole, and the main contradiction is the disorder of one's own will, spirit and soul. SSD is a mental and psychological behavioral disease, and it is suitable to use will-meaning differentiation.
2 Distinguish pathological stages
The treatment of SSD can be divided into three pathological stages: the initial stage is the stage of mental and spiritual disorder in which blood and qi are not combined and the viscera is not damaged, and the pathological changes in this stage are limited to mental activity due to differences in congenital endowment, emotional stimulation and cognitive limitationsIn the middle stage, the mental and spiritual disorders gradually damage the internal organs and body, and the form and spirit affect each otherIn the later stage, the body and spirit are in the same disease stage, "the blood and qi are combined, and the disease is formed", the will and spirit are abnormal, and at the same time, there is serious damage and dysfunction of the viscera. At the beginning, due to the difference in innate endowment, there are differences in the psychological cognition of individuals in dealing with childhood trauma, life experience, stressful events or the prolonged impact of inherent diseases, etc., and the mental and spiritual soul hidden in the five internal organs is the regulation and external manifestation of mental activity, and the abnormality of hyperactivity or weakening occurs. The delirium is prolonged for a long time, and the psychological cognitive deviations and the abnormal behaviors caused by them are not corrected for a long time, resulting in stagnation of qi and organs, poor blood flow, and gradual dysfunction of the organs and physical damage. In the stage of mental disease, the pattern differentiation of will and intention is selected, and in the stage of the same disease, the pattern differentiation of will and intention combined with the pattern differentiation of viscera, qi, blood and fluid is selected. 
3 Dialectical analysis of will
According to the dialectic of will, the basic pathogenesis of SSD is hyperactivity and weakness, biased willingness, and weakness and weakness. 3.1 Pathogenesis main certificate
3.1.1 The soul is weak and weak
The pathogenesis of SSD is closely related to emotional factors. Emotional failure, liver qi is lost in drainage, depression turns into fire, robbing yin and jin, liver yin has no right to collect, blood does not give up the soul, and the liver soul is hyperactive. Emotional sleepiness for a long time, abnormal rise and fall of the qi machine, dysfunction of the liver and lungs, the lungs do not hide qi, the qi is not reluctant, and the liver and soul are hyperactive and insult the lungs, causing them to be cowardly. The chest belongs to the lungs and the flank belongs to the liver, the liver mainly rises and the lungs mainly descend, the liver and soul are hyperactive, the qi is reversed, the lung is insufficient, the form and qi are difficult to suppress, the soul is out of tune, and the qi is contrary to the liver and lungs, then the disease starts from the chest and flank. As a result, the soul is hyperactive and weak, and the patients mostly show symptoms such as chest tightness, flank swelling, dizziness, fatigue, shortness of breath, good breath, poor sleep, etc., and the spirit is mostly anxious and depressed. In the theoretical framework of the dialectical dialectic of will, "spirit" is an innate form of expression that is naturally formed based on form and qi, and essence in and out, which is mainly responsible for instinctive and low-level body functions such as sensation, movement, and reflex, which is the external manifestation of "jing", which is related to the state of "jing", and has the characteristics of inhibition, passivity, and stillness, and plays the role of "calming the shape". "Soul" is a kind of consciousness activity that follows the gods to and from the innate and established and formed in the acquired, representing a higher form of thinking than the spirit, with the ability to process information from the internal and external environment and show corresponding reactions, and is the basis of emotion, cognition, and thinking. The study found that the increase in functional connectivity in some brain regions in SSD patients may be related to dysfunctional processing and information misinterpretation, resulting in high levels of somatosensory amplification;Individual pain thresholds and bilateral middle frontal gyrus, left lower parietal lobe, and right temporal gyrus differed from those in healthy populations. In the state of weakness, the inhibition and stillnessiness are reduced, and the body's collection and processing of internal and external information is in an hyperactive state, and the instinctive activities such as sensation, movement, and reflexes are not effectively controlled, resulting in unnecessary, abnormal, and excessive perception, such as chronic pain or recurrent symptoms such as chest tightness, palpitation, headache, and tinnitus. Excessive use of activities such as thinking, imagination, evaluation, decision-making, and emotion that communicate with the outside world and feed back to the body will cause patients to pay attention to physical symptoms for a long time, causing anxiety and cognitive and behavioral deviationsPatients often repeatedly visit various departments, inquire about relevant information extensively, and even try prescriptions and ** with unknown safety. 
3.1.2 Chi eccentric shake
The soul is weak and weak, the qi has no right to rise and fall, disturbing the kidneys and the blood, the essence is not reluctant, the camp is not hidden, the kidneys are offset, and the spleen is shaking. That is, the somatic symptoms and the adverse mental state caused by them are not corrected, the patients have cognitive and behavioral deviations and changes in thinking patterns, and the regulation of kidney consciousness and spleen intention is abnormal. The heart has the meaning of remembering, and the meaning of the meaning is the will. The purposefulness, concentration, and self-control of the mental action behavior of the "Zhi" represent the subjective initiative and the motivation to transform the objective world. "Yi" represents the forms of thinking such as attention, desire, memory, speculation, etc., which are mental activities with a clear direction, and the directivity and selectivity of the intention are used as the classification indicators of the differentiation of the meaning and syndrome. In the state of ambition, SSD patients pay too much attention to somatic symptoms, most of them ignore or interfere with normal social life, and generally adopt immature defense mechanisms such as somatization and excessive behavior in the face of negative life events, and even rely too much on somatic symptoms as a way of emotional expression, forming cognitive distortionor fear due to persistent concerns about health. In the state of willingness, patients seek medical treatment more often, have low trust and satisfaction with medical treatment, have too much thinking, and are easily disturbed by directivity and selectivity, making it difficult to maintain stable cognitive thinking. The study found that the attention tendency of SSD patients to pay attention to negative emotions was significantly related to negative cognition and emotional neglect in childhood, which provided a new perspective for improving the cognitive and attentional bias of SSD patients. 3.1.3 Weakness and decay
The liver and soul are hyperactive, the lungs are insulted, the will is shaken, the will is not controlled, the soul is out of tune, the viscera is gasified and lost, the internal blood is consumed, and the essence is weak for a long time. If the essence is insufficient, the spirit qi cannot be metapled, the liver and kidney are insufficient, the brain is not filled with the marrow, the medullary sea is not nourished, the mind is exhausted, the subjective will is insufficient, the thinking is dull, the emotion is indifferent, the functions of movement and reproduction are reduced, the circadian rhythm is abnormal, and the overall state of declining energy and insufficient life motivation is presented. Jing is the subtle substance that constitutes the essence of life, which is hidden in the kidneys, metamorphoses into bone marrow, and is injected into the brain. God is the overall manifestation of the vitality of the human body, which summarizes the overall state of communication and coordination of essence, will, mind, soul, and spirit. Spiritual interoperability, refinement of qi and spirit, and control of qi and refinement. In the theoretical framework of the dialectical differentiation of will, "jing" is a material summary of the innate biological instincts acquired by traditional Chinese medicine, which is self-sufficient and does not require the participation of acquired social factors. "Shen" is a functional summary of the acquired volitional thinking and personality traits in traditional Chinese medicine, which is based on the material basis of "jing" and is gradually formed with the participation of social factors. Studies have shown that both physical and mental health dimensions are significantly impaired in SSD patients, and their quality of life is poor. 
3.2 Governing the law
Firstly, the pathological stage of the disease was identified, and the pathogenesis and main syndrome were grasped, and the differences in the early, middle and late stages of the disease were sorted out. Initial stage: the five aspirations are overactive or insufficient, the evidence gradually reaches the stage of the combination, the soul is overwhelmed and weak, the ambition is biased and shaken, and the soul is strengthened and the ambition is reconciled. Middle and late stage: This syndrome is combined with viscera, qi and blood, and the form and spirit are mutually damaged, and they are treated separately according to their prominent contradictions. 3.3. Prescription medication
By searching more than 50 monographs on herbal medicine and prescription literature from the Qin and Han dynasties to the end of the Qing Dynasty, our research group conducted cluster analysis of Zhi, Yi, Soul, Spirit, Jing, and Shen drugs, and the research results enabled the preliminary repair of the Zhi, Yi, Soul, Spirit, Jing, and Shen prescription treatment system. 3.3.1. The initial stage of the combination of the five Zhi anomalies and the certificates
At this stage, the general pathogenesis is that the soul is hyperactive and weak, and the will is biased. The main symptoms are increased body sensitivity, repeated physical symptoms such as dizziness, chest tightness, palpitation, pain, etc., which cause severe anxiety and tension or persistent thoughts, and invest too much time and energy to think about the diseaseSomatic symptoms precede psychiatric symptoms. Concomitant symptoms generally include poor appetite, difficulty falling asleep, easy awakening, dreaminess, or depressed mood, mania, episodic phobia, a sense of impending death, and in severe cases, suicidal thoughts or behaviors. Generally, the tongue is dark red or pale white, the tongue is small, and the lichen is thick and dry. The pulse is mostly seen in the left guan shape slippery potential, the right inch is weak, the left ruler is tight and strong, the right guan is floating, and the overall pulse number. The general ** rule is to calm the soul and strengthen the spirit, reconcile the will, and choose the requiem to strengthen the spirit, and the medicine can be selected ginseng, mulberry white bark, Yuanzhi, Fushen, fengfeng, Guanzhong, citrus aurantium, rehmannia rehmannia, gastrodia, keel, tortoise shell, continuation, wood fragrance, etc. 3.3.2 Middle and late stages of disease and morphology and syndrome
Liver depression and spleen deficiency, soul disharmony, symptoms of dizziness, dizziness, tinnitus, bitter mouth, chest and flank stuffiness, sluggishness, abdominal distention, diarrhea, irritability, confusion, distraction, a small number of patients can see separation and conversion disorders, tongue is mostly pale or yellow, little or no lichen, and the pulse is more thin. The treatment is to soothe the liver and strengthen the spleen, calm the soul, and choose Xiaoyaosan as the base, medicinal Bupleurum chinensis, white peony, Atractylodes, Angelica, parsnip, Schisandra, psoralen, Digupi, psyllium, etc. Those who do not communicate with the heart and kidneys, and do not control the spirit, have headaches, lack of sleep, polydipsia, soreness in the waist and knees, sperm loss in men, menstrual disorders in women, impulsiveness, irritability, forgetfulness, fear, etc., the tongue is red and mossy is less, the pulse is thin in the left inch, and the left ulnar is weak. The treatment is to nourish the kidneys and calm the heart, nourish the mind and determination, and choose Coptis chinensis Qingxin drink as the base, medicinal Coptis chinensis, Rehmannia rehmannia, cypress seeds, calamus, Yuanzhi, amber, sour jujube kernels, Tiandong, Mai Dong, Muxiang, Wujiapi, etc. 
Symptoms include mania, insomnia, red face, abdominal irritability, dry stools, hyperactivity, violent behavior, and a small number of patients can see psychiatric symptoms such as visual hallucinations, auditory hallucinations, and delusions, and the tongue is red and yellow, and the pulse is slippery. The treatment is to clear away heat and phlegm, nourish the heart and calm the nerves, and choose Coptis chinensis warm bile soup as the base, medicinal Coptis chinensis, Banxia, Zhuru, Gardenia, Cassia Shi, Hook Vine, Zombie Silkworm, Floating Wheat, Mulberry White Bark, Fushen, Yizhiren and so on. Patients who have been ill for a long time, have insufficient liver and kidneys, are weak and weak, and the symptoms are fatigue, apathy, night sweats, poor appetite, weight loss, circadian rhythm disorders, loss of interest, persistent low mood, etc., and the tongue is pale and lichen, or slippery without lichen, and the pulse is weak. The treatment is to nourish the kidneys and liver, benefit the essence and fill the marrow, and the party selects Zuogui pill as the base, and the medicinal rehmannia rehmannia, deer horn gum, wolfberry, psyllium, fairy grass, ligustrum, black lotus, mountain corn meat, etc.
4 Auxiliary**
Acupuncture point massage can be used to laxify the soul door, replenish the soul, press the rubbing room, the meaning of the house, and make up for the catharsis. For those with spleen deficiency and liver prosperity, add Taichong, Xingjian, Zusanli, Spleen Yu, etc. For those who do not communicate with the heart and kidneys, add Yongquan, Taixi, Sanyinjiao, Shenmen, etc. For those who burn in the phlegm fire, add Quchi, Hegu, Fenglong, Yinling Spring, etc. For those with liver and kidney insufficiency, add Qihai, Guan Yuan, Kidney Yu, Fuyu, Sanyinjiao, etc. Conventional acupuncture, moxibustion, patching, auricular pressure beans, scalp acupuncture, buccal acupuncture and other methods can also be selected according to the actual situation of the patient. Patients with SSD have deficiencies in their ability to regulate their own emotions and recognize the emotions of others, and are more sensitive to negative emotions and less trusting of others. Psychiatric symptoms are not only the core manifestations of SSD, but also directly affect the development and outcome of the disease. Therefore, it is also necessary to choose psychological methods such as expression, cognition and behavior according to the actual situation, and treat patients with gentleness and patience in the process of diagnosis and treatment, and avoid unnecessary metaphors or hints to channel patients' anxiety and tension. 
5 Conclusion
The spectrum of human diseases continues to change with the course of the times, and mental and psychological diseases show a more severe trend. SSD seriously affects the quality of life and emotional experience of patients, but due to its complexity and heterogeneity, there is no standardized diagnosis and treatment system. The syndrome differentiation and prescription framework of will and intention are suitable for psychiatric, psychological, and behavioral diseases, which provide a new possibility for the diagnosis and treatment of SSD, and the objective evaluation method for the elements of will is being studied. Therefore, we advocate strengthening the early identification and diagnosis of SSD and constructing a comprehensive intervention program with Chinese and Western synergy.
