[Abstract]:Objective: to detect HJURP in hepatocellular carcinoma (Holliday Junction Recognition Protein, Holliday protein expression recognition), and explore the relationship between expression level and prognosis. Methods: by immunohistochemistry, Westernblot, reverse transcriptase polymerase chain reaction and real-time polymerase chain reaction technology from the detection of the expression levels of HJURP protein and RNA levels the use of SPSS21.0 (America) software was used for statistical analysis. The qualitative data using the chi square test. Each set of data for quantitative data must first carry on the normality test, with normal distribution using T test or calibration T test, is not in accordance with the normal distribution of the non parametric test. Comparing the cancer group and paracancer group. The patients in the cancer group respectively according to gender, age, whether there is a history of drinking, whether hepatitis or cirrhosis, clinical stage, Child classification of liver function is divided into sub groups. The immune sub group Group, Westernblot, reverse transcriptase polymerase chain reaction and real-time polymerase chain reaction analysis. Through telephone follow-up to the disease-free survival of each patient, survival analysis and overall survival. Results: (1) the results of PCR analysis showed that cancer and paracancer groups Ct value respectively is 25.9652 + 3.4866 and 31.1120 + 7.3778. two group Ct values were 4.069821 + 4.6855 and 8.7879 + two 7.07246. group of delta delta Ct = 8.4491 + 4.5554 and 13.0779 + 7.0725. according to the formula of relative quantitative value of two groups were 0.8774 + 4.0691 and 0.6674 + 2.4538, P0.001.PCR results subgroup analysis showed that the expression of HJURP and the patients gender, age, whether there is a history of hepatitis or cirrhosis, if there is no relationship between drinking history (P0.05). But according to the clinical stage of the patients were divided into phase I, II, III group, there were 14 people, 17 people, 9 people, three group of Ct = 27.5474 + 1.3655,26.6135 + 1.0607 and 19.1424 + 1.3527, P1-2=0.5760, P1-30.001, P2-30.001. three group Ct values were 7.6850 + 0.3179,4.0306 + 0.3517 and -5.3967 + 0.7401, P1-20.001, P1-30.001, P2-30.001. three groups of delta delta Ct = 11.8607 + 0.1803,9.4389 + 0.1750 and 6.8622 + 0.5081, P1-20.001, P1-30.001. The relative quantitative P2-30.001. value of three groups were 0.0003 + 0.0001,0.0024 + 0.0008 and 0.6321 + 0.2679, P1-2=0.998, P1-30.001, P2-30.001. according to the Child-Pugh classification of liver function were divided into group A, B group, C group, there were 11 people, 22 people, 7 people, three group of Ct = 26.6322 + 1.6156,26.6855 + 1.0166 and 18.6203 + 1.3778, P1-2=0.9760, P1-3=0.001, P2-30.001. three group Ct values were 8.1055 + 0.2907,3.6986 + 0.5547 and -6.1414 + 0.6449, P1-20.001, P1-30.001, P2-30.001. three The delta delta Ct = 12.0627 + 0.1831,9.5259 + 0.266 and 6.85728 + 0.6159, P1-20.001, P1-30.001, P2-30.001. relative quantitative value of three groups were 0.0003 + 0.0001,0.0020 + 0.0006 and 0.8125 + 0.3141, P1-2=0.989, P1-30.001, P2-30.001. (2) WESTERN-BLOT analysis. The results showed that the gray scale of cancer group and paracancer group respectively 1.2109 + 0.0660 and 0.7368 + 0.7503, P0.001. of tumor patients of WESTERN-BLOT subgroup analysis found that HJURP at the protein level and gender, age, whether there is a history of hepatitis or cirrhosis, whether there is a history of drinking. And the clinical stage (0.2645 + 0.1024,1.1362 + 0.1084,1.6556 + 0.1020, P1-20.010, P2-3=0.04, P11-30.01, Child (grade) 1.3286 + 0.0388,1.3253 + 0.0567,1.5776 + 0.1417, P1-2=0.973, P2-3=0.031, P1-3=0.055). (3) immunohistochemistry results showed that cancer were negative, weak positive, positive and strong positive Were 7.5%, 22.5%, 27.5%, 42.5%; paracancer were negative, weak positive, positive and strong positive were 27.5%, 27.5%, 42.25%, 2.75% (P0.001). Immunohistochemical subgroup analysis showed that the expression level of HJURP in tumor tissues and patients' sex, age (P=0.875) (P=0.092) is there, drinking history (P=0.461), whether there is hepatitis or liver cirrhosis history (P=0.911). But the independent and clinical stage (P0.001) and Child classification of liver function (P=0.026) is closely related to (4). Survival analysis showed that low expression group and high expression group average progression free survival was 16.3740 + 1.1140 in August, 14.2830 + 0.6210 months, but the P=0.0400. low expression group and high expression group average overall survival was not significantly different. Conclusion: (1) both at the RNA level or at the protein level, the expression level and clinical tumor tissues are significantly higher in HJURP tissue adjacent to cancer.HJURP staging and Ch ILD grading correlation was not related to sex, age, drinking history, and history of hepatitis cirrhosis. (2) HJURP was associated with disease-free survival but not overall survival.
