Correlation of Genetic Susceptibility Genes to Inflammatory Bowel Disease in Chinese Han Population (CGSGIBDCHP)

November 13, 2021 updated by: Xiao xiao Shao, Second Affiliated Hospital of Wenzhou Medical University
The pathogenesis of IBD is still unclear, and the disease characteristics of IBD patients are affected by genetic susceptibility genes. Therefore, this study aims to explore the relationship between genetic susceptibility genes of IBD and the pathogenesis of IBD in Chinese Han population, in order to clarify the pathogenesis of IBD and provide basis for individualized treatment of IBD.

Detailed Description

The pathogenesis of IBD is still unclear, and the disease characteristics of IBD patients are affected by genetic susceptibility genes. Therefore, this study aims to explore the relationship between genetic susceptibility genes of IBD and the pathogenesis of IBD in Han Chinese, in order to clarify the pathogenesis of IBD and provide basis for individualized treatment of IBD.In this study, 5ml peripheral venous blood was drawn from IBD patients and normal controls for gene testing.To investigate the relationship between polymorphisms of TRAIL, ITGA4, ICAM1, ITGA4, ICAM1, LTA, FCGR3A, TRAP1, TNFRSF1B, CDKN2B-AS1 and susceptibility to IBD in Chinese Han population.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

IBD patients or healthy controls who met the inclusion criteria

Description

Inclusion Criteria:

  • Confirmed IBD patients were collected from the Department of Gastroenterology, The Second Affiliated Hospital of Wenzhou Medical University.According to the consensus of "Diagnosis and treatment of inflammatory bowel disease" formulated by Chinese Society of Gastroenterology, the diagnosis of IBD was established by clinical, laboratory, radiographic, digestive endoscopy and histopathological examination.During the same period, 476 healthy subjects were collected from the physical examination center of our hospital as the normal control group

Exclusion Criteria:

  • Active infection, malignant tumor, congestive heart failure, demyelination of nervous system, allergy to rat derived protein components, etc All subjects were excluded from infectious diarrhea, ischemic enteropathy, radiation enteritis, gastrointestinal tumor, diabetes, systemic lupus erythematosus, rheumatoid arthritis and autoimmune thyroiditis by clinical examination before inclusion.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
IBD group
According to the consensus opinions on diagnosis and Treatment of Inflammatory Bowel Disease (Beijing, 2018) formulated by Chinese Society of Gastroenterology, Chinese Medical Association The diagnosis of IBD was confirmed by clinical, laboratory, radiographic, digestive endoscopy and histopathological examination.
Genetic: 2ml peripheral venous blood was collected to detect genetic genes

Extraction of whole genome DNA: 2 mL of peripheral fasting venous blood was extracted, and edTA disodium was anticoagulant.The whole-genome DNA was extracted strictly in accordance with the instructions of the blood genomic DNA extraction kit (Beijing Tiagen Biochemical Technology Co., LTD., China), and the DNA concentration and purity were detected by nanodrop-1000 spectrophotometer (Thermo, USA). The DNA was diluted to 10 ng/μL and stored in a refrigerator at -80℃ for future use.

(2) Primer design and synthesis: (3) Gene polymorphism detection 4) Resin purification 5) Spot chip and mass spectrometry detection

Other Names:
  • DNA is extracted and genetic testing is performed
control group
During the same period, healthy subjects were collected from the physical examination center of our hospital as subjects of the normal control group. Infectious diarrhea, ischemic bowel disease, radiation enteritis, gastrointestinal tumor, diabetes, systemic lupus erythematosus, rheumatoid arthritis and autoimmune thyroiditis were excluded from all clinical examinations before inclusion.
