Abstract: Objective To lay the foundation for analyzing the mechanism of liver cell injury caused by mtDNA deletion and mutation in patients with obstructive jaundice. Methods 30 patients were randomly selected as obstructive jaundice group (case group) and 10 patients as control group according to the strict condition. Author makes use of the methods of PCR amplification of the entire human mitochondrial genome in 17 mismatch-specific overlapping fragments and gene sequencing results to Preliminary estimate the localizathion of hepatocyte mtDNA damage in patients with obstructive jaundice. Result Deletions and length of partial liver cells were 8429-9591 of about 1. 1 kb, 16024-60 of about 0. 6 kb, 1889-3031 of about 1. 1 kb and 4977bps common deletion and the high mutation rate of some bases in D-loop region. Conclusion There are multiple mtDNA deletions and multiple point mutations in patients with obstructive jaundice
