Correlation analysis on liver function and serum markers of liver fibrosis in patients with fatty liver / 中国综合临床

ABSTRACT

Objective To analyze the changes of serum markers of liver function and liver fibrosis in patients with fatty liver,and to explore the relationship between them,so as to provide scientific basis for the prevention and treatment of fatty liver into hepatic fibrosis. Methods From January 1st,2015 to December 31st, 2015,one thousand three hundred and forty-six healthy cases were selected,and 361 cases of fatty liver were diagnosed by ultrasound. Liver function index of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was detected by automatic biochemical analyzer. Hyaluronic acid (HA),laminin (LN),serum type Ⅲprocollagen peptide ( PC Ⅲ) and type Ⅳ collagen ( C-Ⅳ) were detected by enzyme-linked immunosorbent assay. The correlation between liver function and serum liver fibrosis indexes was analyzed by Pearson parameter analysis. Results The liver function index ALT,AST((69. 04±18. 72) U/L,(59. 78±15. 65)U/L) in fatty liver group were higher than those in the non-fatty liver group((25. 71±10. 25) U/L,(23. 68±8. 23) U/L),the differences were statistically significant ( t＝279. 283,388. 461,P＜0. 05) . Four serum fibrosis index HA,LN, PCⅢ,C-Ⅳ in the fatty liver group were (112. 64±21. 63) μg/L,(125. 85±27. 52) μg/L,(127. 28±29. 37) μg/L,(79. 38±18. 52) μg/L,respectively,which were higher than those in the non-fatty liver group ( (53. 98 ±16. 84) μg/L,(86. 31±20. 46) μg/L,(53. 31±18. 23) μg/L,(57. 26±15. 86 ) μg/L),the differences were statistically significant ( t＝727. 724,170. 432,941. 357,71. 169,P＜0. 001) . The correlation analysis of liver function and serum liver fibrosis indexes showed that ALT and AST were positively correlated with the fibrosis indexes HA,LN,PCⅢ( correlation coefficient r＝0. 230,0. 119,0. 370;0. 363,0. 361,0. 509,P＜0. 001),and which had no significant correlation with C-Ⅳ(P＞0. 05). Conclusion Liver function and serum liver fibrosis index can be used as the important basis for monitoring and diagnosis on the progression of fatty liver disease.
