1. Clinical data 1. 1 General data From July 2005 to April 2006, those who had taken medicine continuously for more than one month in the pediatric outpatient clinic of Dongfang Hospital of Beijing University of Traditional Chinese Medicine were included as the observation subjects. There were 285 cases, including 230 males and 55 females; 14 cases aged < 5 years, 206 cases aged 5 to 12 years, and 65 cases aged 12 to 18 years. The TCM classifications were 125 cases with spleen deficiency and phlegm aggregation, 97 cases with qi-depression and fire, 44 cases with spleen deficiency and liver hyperactivity, and 19 cases with liver and kidney yin deficiency. 1. 2 Diagnostic criteria: According to the 1994 Diagnostic Statistical Manual of Mental Disorders6 4th edition (DSM-IV), multiple motor twitches and one or more vocal twitches, sometimes not necessarily at the same time, were diagnosed. The twitches are sudden, rapid, repetitive, non-rhythmic, and stereotyped movements or vocalizations. o The twitches occur several times a day, usually in bursts, and have lasted for more than 1 year or intermittently, with a twitch-free interval of no more than 3 months. These symptoms cause significant anxiety and significantly interfere with social, professional, and other important areas of activity. The onset was before the age of 18. The symptoms are not directly caused by certain drugs (e.g., stimulants) or medical conditions (e.g., Huntington's chorea or post-viral encephalitis). 2. Treatment Method: Treatment by pacifying the liver, strengthening the spleen and resolving phlegm, using: Radix et Rhizoma Ginseng, Atractylodes Macrocephalae, Poria, Semen Parsley, Pericarpium Citri Reticulatae, Rhizoma Tenuifoliae 10g each, Cicadellariae 6g, Silkworm 10g, Gastrodiae 15g, Radix et Rhizoma Paeoniae 20g. If the qi stagnates and turns into fire, add Chai Hu, Yu Jin, Gardenia, Gentianae; if the liver and kidney have yin deficiency, add Shu Di Huang, Turtle Board, Dragon Bone; if the phlegm is congested, add Green Pores 15g, Bile South Star 10g, Bamboo Roo 6g. 1 dose daily, divided into 2~3 doses with water decoction. 4 weeks is a course of treatment. 3. Treatment results Efficacy criteria: There is no unified efficacy assessment standard for multiple tics in China. The author used the Yale General Tic Severity Scale (YGT SS scale) [2] to assess the motor and vocal tics of children with hyperacusis in five aspects: type of tics, frequency, intensity, complexity, and impact on life or behavior. The YGT SS reduction rate was used as an efficacy criterion according to the literature. The effectiveness of YGT SS was determined by the reduction rate of 60% or more in 63 cases; effective: reduction rate of 30%-59% in 181 cases; ineffective: reduction rate of 30% or less in 41 cases. The total effective rate was 85.6%. YGT SS reduction rate = [ (pre-treatment scale score - post-treatment scale score) A pre-treatment scale score ] @ 100%. The comparison of twitch scores before and after treatment is shown in Table 1. Twitch scores Before treatment After treatment P Motor twitch score 15.05 ± 3.72 7.80 ± 3.68 < 0. 05 Vocal twitch score 15.65 ± 3.99 10.20 ± 3.78 < 0. 05 By t-test, both motor and vocal twitch scores decreased after treatment compared with those before treatment, and the difference was statistically significant. The differences were statistically significant. The prevalence of polydipsia has been on the rise in recent years, with the prevalence in children being about 10 times higher than that in adults, and a significant proportion of adults with polydipsia continue to have the disorder from childhood to adulthood. The common comorbidities of ADHD, OCD, conduct disorder, learning difficulties, mood disorders, and self-injurious behaviors add to the complexity and severity of the disorder, making treatment more difficult and affecting social functioning and recovery to varying degrees. The etiology and pathogenesis of this disease are not yet clear, and currently the main treatment is pharmacological, with dopamine receptor blockers such as haloperidol, Tebretol, and other antipsychotics being used routinely. However, these drugs have many side effects, such as drowsiness, dizziness, fatigue, tachycardia, difficulty in urination, and extrapyramidal reactions, and are prone to rebound after discontinuation. Some children and their parents have difficulty in accepting the side effects caused by a longer period of medication, so they tend to reduce or stop the medication on their own, thus causing recurrence of the disease and affecting the efficacy of the treatment. In view of this, the author has been actively exploring the rules of Chinese medicine in the treatment of children with polydactyly under the guidance of the theory of evidence-based treatment in Chinese medicine for many years. The name of hyperactive tic disorder is not found in classical Chinese medical texts, but according to its clinical symptoms, it belongs to the category of symptoms such as slow frightening wind and mixture. Although hyperactive tic disorder is characterized by dysfunction of the heart, liver, spleen, and kidneys, the liver is the main site of the disorder. In children, "the spleen is always deficient and the liver is always in excess", resulting in internal movement of liver wind, or loss of spleen health, internal growth of phlegm and dampness, and blockage of the meridians by phlegm, leading to liver wind and muscle twitching; wind and phlegm disturb the throat, resulting in strange sounds, and disturbance of the nerves, resulting in obscene speech. Therefore, the main pathogenesis of this disease is spleen deficiency and liver hyperactivity, and wind and phlegm disturbance. The evidence belongs to the deficiency of the root and the symptoms of the symptoms. The treatment is to pacify the liver and strengthen the spleen, resolve phlegm and quench the wind. The combination of the formula and evidence is effective. The children with polydactyly in our department come from a wide range of sources, covering almost all provinces and cities in China, which is somewhat representative. The majority of the children had the disease for more than 1 year, with the longest being 13 years. The clinical observation of 285 cases showed that Chinese herbal medicine can significantly reduce the types of motor and vocal tics, reduce the frequency, intensity, complexity and impact on life and behavior of tics, improve the mood of children, reduce recurrence and have no significant side effects, which is worth promoting. The mechanism of action needs to be further investigated.
