Summary

Tourette Syndrome (TS) children were administered Pei Tu Ning Feng Tang treatment. The differences in gut microbiota composition, peripheral blood stress hormones, oxidative stress markers, cytokines, neurotransmitters, and hair cortisol concentrations were observed before and after treatment. Combined with the differences in tic-like behavioral indicators, the therapeutic efficacy of Pei Tu Ning Feng Tang was evaluated. Additionally, TS children underwent two fNIRS examinations before and after treatment to quantitatively describe the activation of brain function by Pei Tu Ning Feng Tang and to investigate its neural mechanisms against tics. Scores were assessed before and after treatment using the Yale Global Tic Severity Scale (YGTSS) and the Traditional Chinese Medicine Syndrome Score Sheet for Pediatric Tourette Syndrome (Spleen Deficiency and Liver Hyperactivity Type) to observe the efficacy of the medication.

Type	Name	Description
DRUG	Tourette Syndrome (TS) children were administered Pei Tu Ning Feng Tang treatment.	Preparation of Peitu Ningfeng Decoction: Codonopsis pilosula (Dangshen) 10g, Astragalus membranaceus (Huangqi) 10g, stir-fried Atractylodes macrocephala (Baizhu) 5g, Poria cocos (Fuling) 10g, Paeonia lactiflora (Hangshao) 10g, Uncaria rhynchophylla (Gouteng) 10g, honey-fried Glycyrrhiza uralensis (Zhi Gancao) 10g.Soak the above herbs (except Uncaria rhynchophylla) in boiling water for 30 minutes, then decoct for 20 minutes. Add Uncaria rhynchophylla later during the decoction process. Each dose is decocted three times: First decoction: add about 500 mL of water, bring to a boil over high heat, then simmer over low heat for 20 minutes, and filter to collect the decoction. Second decoction: add about 300 mL of water, bring to a boil over high heat, then simmer over low heat for 30 minutes, and filter to collect the decoction. Third decoction: add about 250 mL of water, bring to a boil over high heat, then simmer over low heat for 30 minutes, and filter to collect the decoction.
