Method: Selecting 502 high school students of the Li people from five cities and counties in Hainan Island (namely, Qiongzhong County, Dongfang City, Ledong County, Baoting County and Wuzhishan City) as research subjects in September, 2019;Applying PCR-fluorescence probe method to detect SLCO1B1 and ApoE genotypes of the Li people in Hainan Island, and statistically analyzing the distribution characteristics of gene frequency and the distribution differences in gene polymorphisms between different genders. Meanwhile, detecting the SLCO1B1 and ApoE gene of 527 people from the Han people in five regions mentioned before, so as to analyze the distribution differences of the SLCO1B1 and ApoE gene between the Han people and the Li people. Results: The frequency of each genotype of SLCO1B1 in the Li people in Hainan Island is: *1a/*1a 6.77%, *1a/*1b 27.09%, *1b/1b 41.63%, *1a/*5 0.00%, *1a/*15 4.78%, *1b/15 16.93%., *5/*5 0.00%, *5/*15 0.00%, *15/*15 2.79%;And that of ApoE is: e2/e2 0.40%, e2/e3 17.73%, e2/e4 2.39%, e3/e3 65.54%, e3/e4 12.55%, e4/e4 1.39%. There is no significant difference (P > 0.05) in other genotypes except weak metabolic genotypes (*5/*5, *5/*15 and *15/*15) between the Han and the Li peoples. Conclusion: The gene frequency of SLCO1B1 weak metabolic genotype is dramatically higher in the Li people of Hainan Island than that of the Han people in both Hainan Island and Central and South China, but there is no significant difference in ApoE gene frequency among them. Therefore, clinicians should adjust the dosage of statins and select the types of lipid-lowering drugs according to the differences in patients’ genotypes, and strengthen the management of patients with ApoE4 risk gene.展开更多
