Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide and it includes simple fatty liver disease (NAFL), nonalcoholic steatohepatitis (NASH), liver cirrhosis, and hepatocellular carcinoma-related NASH. The degree of hepatic necrotizing inflammation and fibrosis is closely related to the long-term prognosis of NAFLD patients. Therefore, early monitoring of disease progression and intervention are of great significance. Liver biopsy, as an invasive test, has always been the gold standard for the diagnosis of NAFLD; however, it is not easy to carry out widely in clinical practice. With the development of omics-related research technologies, the potential application value of omics biomarkers such as genomics, transcriptomics, proteomics, glycomics, metabolomics, and so on in the diagnosis of NAFLD has gradually emerged. This review mainly summarizes the research progress of omics biomarkers for NAFLD.

Abstract
Objective: To study the changes of serum N-glycan abundance in patients with liver fibrosis at different stages of hepatitis C, and to establish and evaluate the diagnostic model for clinical application value. Methods: Data of 169 hepatitis C virus-infected cases with liver fibrosis were enrolled. Nine kinds of serum N-glycans were detected and analyzed using DNA sequencer-assisted fluorophore-assisted capillary electrophoresis technology. A binary logistics regression method was used to establish a diagnostic model based on the changes in the relative content of N-glycans in each stage of liver fibrosis. Receiver operating characteristic curve was used to evaluate and compare the diagnostic efficacy with other liver fibrosis diagnostic models. Results: N-glycan diagnostic model (B and C) had highest AUROC= 0.776, 0.827 for distinguishing fibrosis S1~S2 to S3~S4 and S1~S3 to S4 than GlycoFibroTest (AUROC = 0.760, 0.807), GlycoCirrhoTest (AUROC = 0.722, 0.787), aspartate aminotransferase to platelet ratio index (AUROC = 0.755, 0.751), FIB-4 index (AUROC = 0.730, 0.774), and S-index (AUROC = 0.707, 0.744). However, the diagnostic efficacy of model A (AUROC = 0.752) for distinguishing fibrosis S1 with S2~S4 had lower diagnostic potency than that of the aspartate aminotransferase to platelet ratio index (AUROC = 0.807). Diagnostic efficiency was improved when the N-glycan profiling and the aspartate aminotransferase to platelet ratio index were combined to diagnose liver fibrosis in each stage, and the area under the receiver operating characteristic curve was 0.839, 0.825, and 0.837, respectively. Conclusion: The serum N-glycan profiling diagnostic model has potential clinical application value in the diagnosis of liver fibrosis in patients with hepatitis C.

Abstract
Combined with field observation and indoor water immersion test, water holding characteristics of litters from five typical plantations (Platycladus orientalis, Robinia pseudoacacia, Populus alba var. pyramidalis, P. orientalis+R. pseudoacacia, P. alba var. pyramidalis+R. pseudoacacia) in southern and northern mountains of Lanzhou City were examined. Results showed that litter mass under the plantations ranged from 13.50 to 47.01 t·hm-2, with an order of P. alba var. pyramidalis+R. pseudoacacia>P. orientalis+R. pseudoacacia>P. orientalis>R. pseudoacacia>P. alba var. pyramidalis. The percentage of un-decomposed litters was greater than that of semi-decomposed litters in all plantations except for P. orientalis plantations. The maximum water-holding rate of litters ranged from 190.8% to 262.7%, with the greatest value in the P. alba var. pyramidalis+R. pseudoa-cacia and the lowest in P. orientalis plantations. The maximum water-holding capacity of litters was 35.29-123.59 t·hm-2, with an order of P. alba var. pyramidalis+R. pseudoacacia>P. orientalis+R. pseudoacacia>R. pseudoacacia>P. orientalis>P. alba var. pyramidalis. Litter water absorption rate declined linearly within the first hour, and then decreased slowly. Semi-decomposed litters had a higher water-absorption rate than un-decomposed litters. The maximum water retaining amount and effective retaining amount of the litters were P. alba var. pyramidalis+R. pseudoacacia>P. orientalis+R. pseudoacacia>P. orientalis>R. pseudoacacia>P. alba var. pyramidalis. P. alba var. pyramidalis+R. pseudoacacia had the highest effective retaining rate. P. alba var. pyramidalis+R. pseudoacacia plantation had highest capacity for soil and water conservation in southern and northern mountains of Lanzhou City.

Abstract
Objective: To investigate the effect of anluohuaxianwan (ALHXW) using rat model of carbon tetrachloride (CCl(4)) induced liver fibrosis on the expression of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). Methods: Thirty-six male Wistar rats were randomly assigned into control, model and treatment groups. Rats in the model and treatment groups were injected intraperitoneally with 40% CCl(4) (2 ml/kg), and the control group were given isotonic saline twice a week for six weeks. Meanwhile, the treatment group were gavaged with ALHXW solution daily (concentration 0.15 g/ml, 9.9 ml/kg) for 6 weeks, while the control and model groups were given isotonic saline once a day for 6 weeks. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured at the end of third and sixth week. At the end of six weeks, liver tissues were harvested for histopathological evaluation and the detection of mRNA and protein expression levels of MMP-2/13 and TIMP-1/2. According to different data, LSD method, parametric (one-way ANOVA) and non-parametric tests (Kruskal-Wallis H-test and Mann-Whitney U test) were used for statistical analysis. Results: Compared with the model group, ALHXW markedly alleviated liver injury in the treatment group, and thereby improved the general state of rats, liver and spleen morphological characteristics, and ALT and AST levels. Histopathological examination demonstrated that the extent of liver fibrosis was improved (2.75 ± 0.75 vs. 3.55 ± 0.69, P = 0.015) in the treatment group as compared with the model group. The mRNA and protein expression levels of MMP-13 in the treatment group were significantly higher than that of the model group (mRNA: 10.50 ± 7.64 vs. 4.40 ± 2.97, P = 0.029. Protein: 1.15 ± 0.09 vs. 0.78 ± 0.21, P = 0.016), whereas the mRNA and protein expression levels of MMP-2, TIMP-1/2 in the treatment group were significantly lower than that of the model group (mRNA: 4.55 ± 3.29 vs. 7.83 ± 4.19, P = 0.048; 1.66 ± 0.73 vs. 3.69 ± 2.78, P = 0.023; 2.25 ± 1.16 vs. 3.41 ± 1.51, P = 0.049; respectively. Protein: 0.44 ± 0.11 vs. 0.65 ± 0.05, P = 0.03; 0.69 ± 0.06 vs. 1.07 ± 0.21, P = 0.016; 0.46 ± 0.09 vs. 0.81 ± 0.13, P = 0.003; respectively). Conclusion: ALHXW exerts anti-liver fibrosis effects mainly by improving liver function, inhibiting the activation of hepatic stellate cells, enhancing the expression of MMP-13, and inhibiting the expression of MMP-2 and TIMP-1/2.

Abstract
Objective: To evaluate the safety and immunogenicity of one booster dose of inactivated hepatitis A vaccine in young adults. Methods: The subjects were selected from participants in the clinical trial of immunogenicity of inactivated and attenuated live hepatitis A vaccine in young adults. Eligible subjects were those who had received one dose of inactivated or attenuated hepatitis A vaccine, could be contacted and were sero-negative before primary vaccination. All qualified subjects were immunized with one booster dose of inactivated hepatitis A vaccine. The blood samples were collected before booster dose vaccination and 28 days after the immunization. Anti-HAV antibody titer ≥20 mIU/ml was considered to be sero-protected against hepatitis A virus. Results: The GMCs in the inactivated HAV vaccine group and attenuated live vaccine group before booster dose vaccination were 70.80 mIU/ml and 50.12 mIU/ml, respectively, and the sero-protection rates were 94.7% and 65.0%, respectively. After the vaccination of the booster dose, the sero-protection rates in both groups were 100.0%, and the GMCs were 2 816.09 mIU/ml and 2 654.55 mIU/ml, respectively. Conclusion: The GMCs and sero-protection rates of anti-HAV antibody in young adults declined after three years of the primary vaccination. However, the higher GMC and sero-protection rate were observed in the inactivated vaccine group than in the attenuated live vaccine group. Significant increases of GMC levels were observed in both groups after one booster dose vaccination.
