Are patients' sedation preferences at gastroscopy influenced by preceding patients' decisions?
Patients' sedation decisions are not influenced by preceding patients' decisions. Most patients attending for out-patient gastroscopy have already decided about sedation.
In this study, we discovered A to T point mutation at nucleotide 613 (A613T) and G to T point mutation at nucleotide 462 (G462T) in the polβ gene through 538 EC patients cohort study. A613T and G462T variant of DNA polymerase β weaken chemotherapy sensitivity of esophageal cancer.
