The aim of this study is to detect the expression levels of vitamin D, Treg, and Th17 in the peripheral blood of patients with Parkinson\'s disease (PD), investigate the impact of Treg/Th17 imbalance on PD patients, and explore the effects of vitamin D intervention on Treg/Th17 imbalance and clinical outcomes. Furthermore, this study aims to delve into the potential mechanisms of vitamin D deficiency and Treg/Th17 imbalance in the pathogenesis of Parkinson\'s disease, ultimately providing new theoretical evidence for the research, prevention, and treatment of PD.
FromJanuary 2023 to July 2024, 50 PD patients and 50 health control groups were collected. All subjects were from the Parkinson\'s outpatient clinic and ward of the Department of Neurology, Suzhou Hospital Affiliated to Anhui Medical University. This study was approved by the Medical Ethics Committee of Suzhou Municipal Hospital and signed an informed consent form. The gender, age, identity registration, place of origin, marital status, education level, occupation, smoking, drinking, occupational exposure, body mass index, home address and contact information of the patients were collected for detailed registration. Current medical history, past history, family history, medication use, physical examination, previous relevant auxiliary examination results, etc. Evaluation scales: H-Y Staging Scale, UPDRS Scale, Breg Balance Scale, MMSE Intelligence Scale, MoCA Scale, SDS Depression Self-Rating Scale, SAS Anxiety Self-Rating Scale, PDSS Parkinson\'s Disease Sleep Scale. Peripheral blood of patients and control groups were sampled to determine the levels of vitamin D, Treg and Th17. PD patients were divided into vitamin D deficiency group and vitamin D non-deficiency group according to the detection of vitamin D. Vitamin D deficiency group was randomly divided into intervention group and non-intervention group. The intervention group was supplemented with vitamin D, and the non-intervention group was not treated. The above scale and peripheral blood vitamin D, Treg and Th17 levels were evaluated after 3 months of follow-up and compared with the pre-intervention and non-intervention groups. Statistical analysis was carried out using SPSS26.0 and GraphPad Prism v.9.

UPDRS
Each item in the UPDRS (Unified Parkinson's Disease Rating Scale) is scored on a scale of 0 to 4, with 0 indicating normal and 4 indicating the most severe symptoms. The UPDRS can be divided into four subscales: the first subscale is used to assess the degree of mental activity, behavior, and emotional disorders in Parkinson's disease patients; the second subscale evaluates the patients' ability to perform activities of daily living; the third subscale, known as UPDRS-III, is the focus of the UPDRS scoring and assesses the motor function of PD patients, using 18 sub-items and a total of 132 points to describe the main motor symptoms of Parkinson's disease; the fourth subscale is used to evaluate treatment-related complications that occur during the course of PD treatment.
Time frame: Evaluation at the time of enrollment and intervention after three months
Berg balance scale
This scale consists of 14 items, each scored from 0 to 4. The sum of these items gives a total score ranging from 0 to 56, with higher scores indicating better balance.
Time frame: Evaluation at the time of enrollment and intervention after three months.
MMSE
This scale consists of 11 items, covering inquiries about orientation such as time and place, as well as assessments of memory, calculation ability, attention, recall ability, language skills, and visuospatial abilities. The language test further includes sub-tests for repetition ability, naming ability, command comprehension, reading ability, and writing ability. The total score for the MMSE is 30, and the entire test takes about 8-10 minutes to complete. A higher score indicates better cognitive function.
Time frame: Evaluation at the time of enrollment and intervention after three months
MoCA
It is an assessment tool used for rapid screening of cognitive dysfunction. It covers eight cognitive domains: visuospatial skills, executive function, memory, language, attention and concentration, calculation, abstract thinking, and orientation. The total score is 30, with a score of ≥26 considered normal.
Time frame: Evaluation at the time of enrollment and intervention after three months
SDS
This scale is an effective clinical tool for measuring subjective feelings of depression. It is a self-rating scale consisting of 20 items, each rated on a 4-point scale.
Time frame: Evaluation at the time of enrollment and intervention after three months
SAS
This scale is a self-rating scale consisting of 20 items, each rated on a 4-point scale, used to assess the subjective feelings of patients with anxiety.
Time frame: Evaluation at the time of enrollment and intervention after three months.
