Cut-off was 85 ng/ml (Fig. 2, E). The PPV, NPV, and diagnosing accuracy were 73.11 , 54.78 , and 68.64 , respectively. If the cut-off was set at 138.4 ng/ml for cirrhosis (S 3.5?) diagnosis, the sensitivity and specificity were 38.24 (22.17?6.44 ) and 90.18 (87.00?2.80 ) UKI-1 chemical information respectively (Fig. 2.F). The PPV, NPV, and diagnosing accuracy were 94.95 , 23.21 , and 86.44 , respectively.Which factors related with serum GP73 levels?Multivariate ordinal logistic regression analysis was performed to adjust other potential confounders (Sex, Age, ALT, total bilirubin, albumin, Platelet). The results showed that serum GP73 was an independent risk factor of liver fibrogenesis in CHB patients with nearly normal ALT. The relative risk was increased 1.106 with the serum GP73 increasing 10 ng/mL. The results were showed in table 3. To explore the causes of GP73 increasing in serum, we further performed a Pearson’s correlation analysis on several biomarkers, which reflected virus replication, hepatocytes injury, and other liver functions. As Fig. 3A and 3B showed, that ALT, total bilirubin (Tbil) were positively correlated with serum GP73 concentration. The correlation coefficient r were 0.25, 0.18, respectively (Fig. 3, B, F). The Terlipressin chemical information interesting data was that ALT seemed not significantly correlated with GP73 concentration in 472 patients with nearly normal ALT (r = 0.014, p = 0.76), by contraries, 26001275 the total of 633 patients was (r = 0.25, p = 0.0003) (Fig. 3B, Table 2). Similarly, although HBV DNA was not correlated with serum GP73 concentration (r = 0.01, p = 0.89), the serum GP73 concentration of patients with HBV DNA above 4log was significantly higher than those of patients with HBV DNA below 4 log (p = 0.007) (Fig. 3C and 3D; Table 2). The other interesting result was that patient’s GP73 levels were negatively correlated with their ALB levels (Fig. 3E). To further validate GP73 expression in liver tissue with different fibrotic gradings, we observed character of GP73 staining in different biopsy sample. Immunohistochemical analysis showed that GP73 positive cells mainly scattered in parenchymal cells, but several non parenchymal cells also positive staining (Fig. 4). This result was consistent with Iftikhar R, et al. [12], report. Compared with mild fibrotic tissue, GP73 was strongly expressed in significant or severe fibrotic liver tissue.274 197 9371.90655.28 72.52653.07 88.35677.53 137.0689.65.33?8.48 65.08?9.98 72.38?04.3 115.5?58.25 99 106 19449.13617.39 65.00641.52 91.88688.7* 81.93663.81 83.08658.41.95?6.31 56.72?3.29 74.79?09.0 72.89?0.96 66.20?9.. 761 patients received liver stiffness measurements; b. 472 patients with nearly normal ALT; c. 633 patients with chronic hepatitis B infections; * P,0.05 Compared with patients with HBV DNA less than 4 Log. doi:10.1371/journal.pone.0053862.t0.73?.80).
