Study Overview
Brief 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.

Outcomes
Primary Outcomes
Functional near-infrared spectroscopy (fNIRS) was used to detect the degree of brain function activation.
Time Frame: From enrollment to the end of the one-month treatment period
Functional near-infrared spectroscopy (fNIRS) was used to obtain real-time changes in oxygenated hemoglobin (Oxy-Hb) and deoxygenated hemoglobin (Deoxy-Hb) in cerebral cortical tissues under specific conditions, indirectly reflecting alterations in cerebral aerobic metabolism during brain activity. Children with Tourette syndrome (TS) underwent two fNIRS examinations before and after treatment to quantitatively describe the degree of brain function activation by Pei Tu Ning Feng Tang and to investigate its neural mechanisms underlying the suppression of tics.Unit: mmol/L
Relative and absolute quantitative analysis of the gut microbiota.
Time Frame: From enrollment to the end of the one-month treatment period
Fecal samples collected from children with TS were analyzed to determine the composition and relative abundance of the gut microbiota. Additionally, representative samples were randomly selected for absolute quantitative analysis of the gut microbiota, reflecting the actual abundance of each microbial taxon and the true differences in samples before and after treatment.In relative quantitative analysis, results are expressed as percentages (%). In absolute quantitative analysis, results are reported as 16S rRNA gene copies per gram of sample (copies/g).
Determination of Short-Chain Fatty Acids in Feces
Time Frame: From enrollment to the end of the one-month treatment period
In this project, fecal samples were collected from children with TS, and the short-chain fatty acids (SCFAs) in these samples were measured before and after treatment.The commonly used unit for determining SCFAs in feces is micromoles per gram of wet stool weight, i.e., μmol/g wet weight.
Analysis of Stress Hormones
Time Frame: From enrollment to the end of the one-month treatment period
Levels of stress hormones in peripheral blood were measured before and after treatment.For example, cortisol is commonly measured in nanomoles per liter (nmol/L).
Analysis of Oxidative Stress Markers
Time Frame: From enrollment to the end of the one-month treatment period
Levels of oxidative stress markers, including superoxide dismutase (SOD), nitric oxide (NO), and malondialdehyde (MDA), in peripheral blood were measured separately before and after treatment.The units are as follows: superoxide dismutase (SOD) activity in U/mL, nitric oxide (NO) metabolites in μmol/L, and malondialdehyde (MDA) in nmol/mL.
Analysis of Cytokines
Time Frame: From enrollment to the end of the one-month treatment period
Levels of IL-1β, IL-6, and TNF-α in peripheral blood were analyzed before and after treatment.Unit: picogram per milliliter (pg/mL)
Concentration of Neurotransmitters
Time Frame: From enrollment to the end of the one-month treatment period
In this project, the concentrations of neurotransmitters including dopamine (DA), glutamate (Glu), and gamma-aminobutyric acid (GABA) in peripheral blood were measured before and after treatment.The units are as follows: dopamine (DA) in pg/mL, glutamate (Glu) in μmol/L, and gamma-aminobutyric acid (GABA) in nmol/L or pg/mL.
