Objective:To explore the correlation between imaging features of children with tic disorders and their features assessed by the Yale Global Tic Severity Scale (YGTSS).Methods:A retrospective study.A total of 33 children with tic disorders treated in the Department of Child Rehabilitation, the First Affiliated Hospital of Xinxiang Medical University from January 2022 to March 2023 were included in the tic disorder group, and 10 healthy age-matched children received physical examination during the same period were included in the healthy control group.Under the functional positioning of functional magnetic resonance imaging (fMRI), the active area of children with tic disorders at varying degrees was found.In the region of interest (ROI), localization monitoring and diffusion tensor imaging (DTI) were performed, and the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were recorded.In the same ROI (bilateral thalamus, genu of internal capsule, splenium of corpus callosum, globus pallidus, caudate nucleus) of children in healthy control group, ADC and FA were recorded.Imaging data were compared between groups using the independent sample t test, and their correlation with YGTSS scores was identified by the Pearson correlation analysis. Results:There were significant differences in ADC of the left thalamus (0.869±0.077 vs.0.794±0.083, P=0.022), the right thalamus (0.853±0.055 vs.0.798±0.054, P=0.014), the left caudate nucleus (0.871±0.121 vs.0.787±0.052, P=0.003) and the right caudate nucleus (0.856±0.075 vs.0.788±0.063, P=0.010) between tic disorder group and healthy control group.No significant differences were detected in ADC of the remaining ROI between groups (all P>0.05). There were significant differences in FA of the left thalamus (0.259±0.050 vs.0.344±0.077, P=0.007), the right thalamus (0.265±0.057 vs.0.347±0.095, P=0.026) and the right caudate nucleus (0.168±0.118 vs.0.309±0.181, P=0.041) between tic disorder group and healthy control group.No significant differences were detected in ADC and FA between children with mild and moderate tic disorders (all P>0.05). ADC of the left thalamus and the right caudate nucleus were significantly correlated with YGTSS scores in children with tic disorders ( r=0.407 and 0.372, respectively; all P<0.05). FA of the right thalamus was negatively correlated with YGTSS scores in children with tic disorders ( r=-0.439, P<0.05). Conclusions:ADC of the thalamus and caudate nucleus, and FA of the right thalamus are significantly correlated with YGTSS scores of children with tic disorders.High ADC of the left thalamus and the right caudate nucleus are correlated with high YGTSS scores, indicating a severe symptom of tic disorder in children.A high FA of the right thalamus is correlated with low YGTSS scores, indicating a mild symptom of tic disorder in children.

This study aims to comprehensively evaluate the clinical value of Shaoma Zhijing Granules(SZG), Changma Xifeng Tablets(CXT), and Jiuwei Xifeng Granules(JXG) in the treatment of children with tic disorder with the method of rapid health technology assessment(RHTA), which is expected to serve as a reference for medical and health decision-making and clinical rational use of drugs in children. To be specific, relevant articles were retrieved from eight databases and three clinical trial registry platforms. After the quality evaluation, rapid assessment was carried out from the dimensions of disease burden and unmet needs, technical characteristics, safety, efficacy and economy, and the results were analyzed and presented descriptively. A total of 22 articles(1 in English, 21 in Chinese) were screened out: 18 randomized controlled trials(RCTs) and 4 clinical controlled trials(CCTs). Among them, 5 were about the SZG(all RCTs) and 9 were on CXT(6 RCTs and 3 CCTs). The rest 8 focused on JXG(7 RCTs and 1 CCT). Moreover, the overall risk of bias for 94.40% RCTs was evaluated as "some concerns" and only one(5.60%) had high risk of bias. In terms of quality, the 4 CCTs scored 5-6 points(<7 points), suggesting low quality. SZG alone or in combination with tiapride has obvious advantages in improving traditional Chinese medicine syndromes and tic symptoms compared with tiapride alone, with the average daily cost of CNY 79.44-119.16. Compared with conventional western medicine or placebo, CXT alone or in combination with conventional western medicine can improve the total effective rate and alleviate tic symptoms, and the average daily cost is CNY 22.50-67.50. JXG alone or in combination with conventional western medicine can effectively relieve tic symptoms compared with conventio-nal western medicine or placebo, with the average daily cost of CNY 82.42-164.85. The adverse events related to the three Chinese patent medicines mainly occurred in the digestive, respiratory, and nervous systems, all of which were mild. In general, SZG, CXT, and JXG are effective for children with tic disorder. They have been approved to be used in this field, of which SZG was approved in 2019, with the most up-to-date research evidence and high-quality RCT in Q1 journals. However, the comparative analysis of the three was affected by many factors, which should be further clarified. Based on the large sample data available in multiple dimensions, a comprehensive comparative evaluation of the three Chinese patent medicines should be carried out, thereby highlighting the advantages and disadvantages of them and serving a reference for rational clinical use and drug supervision.

The pathogenesis of tic disorder in children is closely related to the dysfunction of the internal organs, especially the lung, spleen and liver. The main causes of tic disorder caused by visceral disorders are as follows: lung guard is the main cause of the disease, liver wind is the key to the pathogenesis and spleen deficiency and wind phlegm are the pathological basis. At the same time, the lung, liver, and spleen are mutually restrictive and affect each other. The main manifestations are that if the lung is affected by evil, the wood will punish the gold; if the spleen is insufficiency and the liver is hyperactive, the earth deficiency will be leading to over-restriction by wood. Based on the understanding of the related theories about viscera's disease and viscera's generation, we pay attention to distinguish the etiology and pathogenesis of the viscera, and we treat tic disorders based on syndrome differentiation of lung, liver and spleen with curative effect.

Tic disorder (TD) is a common neuro-developmental disorders in children during school age. The cause is complex and it can be induced or aggravated by varies of factors such as genetics, exogenous pathogens, and emotions. TD affects children's self-cognition, academic level, and social function, and causes parents to have unhealthy psychological states such as anxiety and depression, and affects family harmony. Therefore, clinical attention should not only be paid to the treatment of this disease, but also to prevention and nursing care. Incubative evil theory is one of the important theories of Traditional Chinese Medicine. This theory can help to treat and prevent diseases. Incubative evil is characterized by no symptoms with spontaneous attack by latent pathogen, but symptoms appearance induced by the pathogen. The pathological process of TD is similar to incubative evil characteristics. This paper discusses the prevention and nursing care of children's tic disorder based on the theory of incubative evil.

The paper introduces the clinical experience of GAO Hong in treatment of tic disorder. GAO Hong believes that tic disorder results from the primary qi deficiency and mind disturbance. Acupuncture for cultivating the primary and regulating the mind is proposed specially for tic disorder. This acupuncture technique focuses on harmonizing and regulating governor vessel and conception vessel. In clinical practice, the conception vessel acupoints on the abdomen and the governor vessel acupoints on the head are selected particularly, e.g. Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6) and Guanyuan (CV 4) on the abdomen; Baihui (GV 20), Shenting (GV 24), Benshen (GB 13) and Yintang (GV 24+) on the head. The needling sequence and the insertion depth are emphasized, which affect the curative effect and GV 20 is generally punctured first. Besides, considering to the type of disorder and the affected site, tic disorder is treated in view of both syndrome/pattern differentiation and symptom differentiation.
