Developmental phase

Assessment
Primary outcomes Esophageal mucosal barrier dysfunction in biopsy specimens of ENSC and LVL, which are exposed by acetaldehyde
Key secondary outcomes 1)Level of tight junction protein (TJP)/adhesion junction protein (AJP) in biopsy specimens of ENSE and LVL
2)Level of TJP/AJP RNA in biopsy specimens of ENSE and LVL
3)Oxidative stress marker, endogenous oxidase, and microRNA level in biopsy specimens of ENSE and LVL
4)The relationship between the epithelial barrier dysfunction and the amount of drinking and smoking or ALDH2/ADH1B polymorphism in biopsy specimens of ENSE and LVL
