ObjectiveTo investigate the serum level of ceruloplasmin in patients with different stages and etiologies of liver diseases. MethodsA total of 1077 patients with liver diseases who were hospitalized in Department of Hepatology, The First Hospital of Jilin University, from January 2012 to January 2018 were enrolled, and the serum level of ceruloplasmin was analyzed for the patients with different liver diseases. The Kruskal-Wallis H test was used to compare the level of ceruloplasmin between the patients with virus-related liver diseases with different liver functional states, and a Spearman correlation analysis was used to investigate the correlation of ceruloplasmin with other biomarkers. ResultsIn the Wilson’s disease group, 97.6% (41/42) of the patients had a serum ceruloplasmin level of ＜0.2 g/L and 881% (37/42) had a level of ＜0.1 g/L. In the non-Wilson’s disease group, 24.3% (251/1035) of the patients had a ceruloplasmin level of ＜0.2 g/L and 0.2% had a level of ＜0.1 g/L. There was a significant difference in the serum level of ceruloplasmin between the patients with virus-related liver diseases with different liver functional states, and the patients with chronic viral hepatitis, severe viral hepatitis, and viral hepatitis cirrhosis had a significantly lower level than those with acute viral hepatitis and virus-related liver cancer (P=0005, P＜0.001, P=0.001, P=0.027, P＜0.001, and P=0.001). In the patients without Wilson’s disease, serum ceruloplasmin was positively correlated with albumin and prealbumin (r=0.068 and 0.091, both P＜0.05) and was negatively correlated with prothrombin time (r=-0.297, P＜0.05). ConclusionCeruloplasmin often decreases significantly in patients with Wilson’s disease, with a slight reduction in patients with other types of liver diseases. For these patients, it should be determined whether the reduction in ceruloplasmin is caused by hepatocyte injury or the presence of Wilson’s disease.

Objective To investigate the effect of Huangzhi oral liquid on ferroptosis and apoptosis of hepatocytes in acute hyperlipidemia mice based on abnormal lipid metabolism.Methods Forty SPF grade C57BL/6 mice were randomly assigned to the normal control group,the model group,Huangzhi oral liquid low-dose and high-dose groups,and fenofibrate group,with 8 mice in each group.All administration groups were given Huangzhi oral liquid and fenofibrate by gavage at corresponding doses,while the normal control group and the model group were given the same dose of distilled water for a period of 5 days.on the third day of administration,in addition to the normal control group,other groups were injected intramuscularly with Triton WR-1339 to establish a hyperlipidemia model.After the administration,the serum lipid levels and liver function in mice were detected.The pathological changes of liver were observed by HE staining and lipid accumulation was observed by oil red O staining.The iron content in liver tissues was detected by tissue iron assay kit.The changes in protein expression of ABCA1,ABCG5,LXRα,ASGR1,cleaved-PARP,cleaved-caspase 3,Bcl2,Bax,TFR1,SLC7A11,GCLM,GPX4 and FTH1 in liver were detected by Western Blot.Results Compared with the model group,Huangzhi oral liquid could reduce the lipid vacuoles in liver tissues,alleviate the degree of lipid degeneration,reduce the content of TC,TG,LDL-C,AST and ALT in serum,increase the content of HDL-C,increase the protein expression levels of ABCA1,ABCG5,LXRα,Bcl-2,SLC7A11,GCLM,GPX4 and FTH1 in mice liver tissues,reduce the protein expression levels of ASGR1,cleaved-PARP,cleaved-caspase 3,Bax and TFR1.Conclusion Huangzhi oral liquid can alleviate the abnormal lipid metabolism in acute hyperlipidemia mice,thus alleviates hepatocyte apoptosis and ferroptosis.

Objective:To investigate the relationship between dietary vitamin A intake and its sources in the first trimester and gestational diabetes mellitus (GDM).Methods:A prospective study was conducted to select women at 6-14 weeks of gestation in an obstetric clinic of a maternal and child health care medical institution in Chengdu in 2017. The types and quantities of food during the first trimester were collected by 3-day 24-hour dietary recalls. Dietary vitamin A intake was calculated based on the Chinese Food Composition Table (2018), and it was divided into animal and plant vitamin A intakes according to its food sources. An oral glucose tolerance test was performed at 24-28 weeks of gestation to diagnose GDM according to the Chinese guidelines for diagnosis and treatment of gestational diabetes mellitus (2014). According to the estimated average requirement (EAR) and recommended nutrient intake (RNI), dietary vitamin A intake was divided into low-level group (RNI). Animal and plant vitamin A intakes were divided into four groups (Q1-Q4) according to the quartile method, respectively. The association between dietary vitamin A intake, its different sources of vitamin A intake and GDM in the first trimester was analyzed by log-binomial regression models.Results:A total of 1 298 valid samples were finally included. The average dietary vitamin A intake, animal and plant vitamin A intakes in the first trimester were 341.1 (227.8-501.0) μgRAE/d, 139.3 (69.6-195.3) μgRAE/d and 184.2 (99.4-301.1) μgRAE/d, respectively. After adjusting for confounding factors, log-binomial regression analysis showed that the risk of GDM in high-level group of dietary vitamin A intake was lower than that in low-level group [ RR (95% CI):0.53 (0.36-0.80)]. Pregnant women in the highest quartile of animal vitamin A intake had a lower risk of GDM than those in the lowest quartile [ RR (95% CI):0.66 (0.47-0.95)]. No relationship between plant vitamin A intake and GDM was found. Conclusion:Dietary vitamin A intake in the first trimester is associated with the occurrence of GDM, and higher intake than RNI may reduce the risk of GDM. Higher vitamin A intake from animal-derived food is associated with decreased risk of GDM.
