Abstract:Objective To investigate the efficacy of atorvastatin combined with ursodeoxycholic acid in the treatment of non-alcoholic fatty liver disease and its effect on the levels of nuclear factor kappa B (NF-κB) and transforming growth factor (TGF) -β in serum. Methods Totally 112 patients with NAFLD in our hospital from January 2013 to October 2017 were included in this study. The patients were divided into the observation group and the control group by random number table method, 56 patients in each group. The patients in the observation group was treated with atorvastatin combined with ursodeoxycholic acid, while the patients in the control group was treated with atorvastatin. All patients were treated for 6 months. Body mass index (BMI), waist hip ratio (W/H), liver function, blood lipid, B-ultrasound score, serum levels of NF-κB and TGF-β were compared between the two groups. Results There was no significant difference in BMI and W/H between the two groups after treatment (P?>?0.05). After treatment, the levels of ALT, AST and ALP in two groups were significantly decreased, the levels of ALT, and AST in the observation group were significant lower than that in the control group (P?0.05). The levels of TC and TG in the two groups were decreased after treatment, and the observation group was lower than the control group (P?0.05). Two groups of ultrasound scores were significantly decreased, and the observation group was lower than the control group (P?0.05). The level of serum NF-κB decreased significantly in the observation group, and was lower than that in the control group (P?0.05). Serum TGF-β of two groups decreased, and the observation group was lower than the control group (P?0.05). Conclusions Atorvastatin combined with ursodeoxycholic acid is effective on the treatment of NAFLD, and can reduce serum NF-κB and TGF-β levels.
