Logistic regression and the area under the receiver operating characteristic curve(AUC) were used to evaluate the influencing factors and diagnostic performance of PIVKA-Ⅱ for HCC, respectively.RESULTS Elevated PIVKA-Ⅱ levels were independently positively associated with alcohol-related liver disease, serum alkaline phosphatase(ALP), and total bilirubin(TBIL) for CLD patients and aspartate aminotransferase(AST) and tumor size for HCC patients(all P < 0.05). Serum PIVKA-Ⅱ were significantly lower in patients with viral etiology, ALP ≤ 1 × upper limit of normal(ULN), TBIL ≤ 1 × ULN, and AST ≤ 1 × ULN than in those with nonviral disease and abnormal ALP, TBIL, or AST(all P < 0.05), but the differences disappeared in patients with early-stage HCC. For patients with TBIL ≤ 1 × ULN, the AUC of PIVKA-Ⅱ was significantly higher compared to that in patients with TBIL > 1 × ULN(0.817 vs 0.669, P = 0.015), while the difference between ALP ≤ 1 × ULN and ALP > 1 × ULN was not statistically significant(0.783 vs 0.729, P = 0.398). These trends were then more prominently perceived in subgroups of patients with viral etiology and HBV alone.CONCLUSION Serum PIVKA-Ⅱ has better performance in detecting HCC at an early stage for CLD patients with normal serum TBIL.展开更多

METHODS： This study was designed as a prospective, randomized and controlled clinical trial. Forty two patients after portal hypertension surgery were randomly assigned into 2 groups： control group （n = 20） and supplemental group （adding Gin and rhGH, n = 22）. Every patient received isocaloric and isonitrogenous standard total parenteral nutrition （TPN） starting 3 d after surgery for 7 d. Blood samples were obtained before surgery and at the 3rd and 10th day postoperatively. Host immunity was evaluated by measuring levels of CD4, CD8, CD4/CD8, IgG, IgM and IgA, and the inflammatory responses were determined by assessing IL-2, TNF-α and C-reactive protein （CRP） levels. Intestinal permeability and integrity was evaluated by L/M test and histological examination, respectively. RESULTS： On postoperative d 10, CD4, CD4/CD8, IgG and IL-2 levels in supplemental group were significantly higher than those in control group （33.7±5.5 vs 31.0 ± 5.4, P 〈 0.05, （1.17±0.32 vs 1.05 ± 0.15, P 〈 0.05, 13.94±1.09 vs 12.33±1.33, P 〈 0.05, and 368.12 ± 59.25 vs 318.12 ± 45.65, P 〈 0.05, respectively）, whereas the increase in serum TNF-α concentration was significantly reduced （41.02 ± 27.56 vs 160.09 ± 35.17, P 〈 0.05）. The increase in L/M ratio was significantly lower in the supplemental group than in the control group （0.0166 ± 0.0017 vs 0.0339 ± 0.0028, P 〈 0.05）. Moreover, mucosal integrity in the supplemental group was better than in the control group.CONCLUSION： Postoperative administration of TPN supplemented with Gin and rhGH in patients after portal hypertension surgery improves immune function, modulates inflammatory response, prevents the intestinal mucous membrane from atrophy and preserves intestinal integrity.展开更多
