目的研究经动脉导管化疗栓塞术(TACE)治疗原发性肝癌围术期血清异常凝血酶原(DCP)和磷脂酰基醇蛋白聚糖-3(GPC3)水平变化的临床意义。方法纳入90例接受TACE术原发性肝癌患者作为研究对象,分别在术前1d和术后1 w时检测血清DCP和GPC3水平,分析血清DCP和GPC3下降比例判断TACE疗效的价值,比较血清DCP和GPC3不同下降比例患者生存率。结果 CR者11例,PR者20例,SD者36例,PD者23例。不同疗效患者血清DCP和GPC2水平比较,差异有统计学意义(P0.05)。各组血清DCP和GPC2水平两两间比较,差异均有统计学意义(P0.05)。ROC分析显示血清DCP和GPC3下降比例判断TACE疗效的AUC分别为0.788和0.775(S.E.=0.054,0.051;95%CI=0.683-0.893,0.676-0.874;P均=0.000)。灵敏度分别为0.645和0.839,特异度分别为0.864和0.661,最佳截断值分别为40.50%和30.50%。90例患者随访时间7~48个月,死亡36例,失访3例。血清DCP和GPC3不同下降比例患者生存率比较,差异均无统计学意义(Log rankχ~2=2.604,1.603;P=0.107,0.205)。结论治疗前后血清DCP和GPC3下降比例有助于判断TACE治疗原发性肝癌的疗效,指导临床,但其对判断患者预后的价值仍有一定局限性。 相似文献

Objective To explore the relevance between serum XCL1 levels and liver damage in hepatitis B patients.Methods The serum concentration of XCL1 was detected by enzyme linked immu-nosorbent assay (ELISA).Peripheral blood T-cell subsets were detected by flow cytometry (FCM).Liver function was assayed by automatic biochemistry analyzer, hepatitis B antigen/antibody semi-quantitative index was detected by time-resolved fluorescence analyzer, and HBV-DNA load was detected by automatic fluorescence quantitative PCR.Results Serum concentration of XCL1 in control group ( n = 20), mild chronic hepatitis B (CHB) group ( n =29), moderate CHB group ( n =20) and severe CHB group ( n =26)were (8.24±1.94) pg/ml, (10.99±1.94) pg/ml, (12.83 ±2.59) pg/ml, (13.72 ±3.13) pg/ml,respectively.The concentration of XCL1 in all CHB groups was significantly higher than control group ( P< 0.05 ).The concentration of XCL1 in severe CHB group was significantly higher than mild CHB group (P < 0.05).XCL1 was positively correlated with ALT, AST, TBIL and DBIL, and the coefficients were (r =0.463、 0.472、 0.413、 0.440, P <0.01 ), respectively.The serum XCL1 levels in hepatitis B virus with low load group was lower than hepatitis B virus with high load group.The percentage of CD4 + T in hepatitis B virus with low load group and high load group were (41.26 ± 11.33)%, (33.01 ± 5.96)%,and the difference was statistically significant.Conclusion Serum concentrations of XCL1 were closely related to the degree of liver inflammation in hepatitis B patients.XCL1 may be involved in the process of chronic hepatitis B. 相似文献

目的探讨乙型肝炎患者血清白细胞介素(IL)-32和IL-6的变化及其临床意义。方法对92例乙型肝炎患者和30例健康者用ELISA法检测外周血清IL-32和IL-6水平变化。结果 (1)乙型肝炎组与对照组血清IL-32水平比较差异有统计学意义(F=108.494,P〈0.001),急性乙型肝炎(AHB)组血清IL-32水平最高,慢性乙型肝炎(CHB)组随轻、中、重分型逐渐升高;乙型肝炎组与对照组血清IL-6水平比较差异有统计学意义(F=139.256,P〈0.001),依AHB、CHB轻、中、重度逐渐升高。(2)HBV DNA阳性组IL-32、IL-6水平较阴性组为高,差异无统计学意义;高、中、低病毒载量组之间血清IL-32、IL-6水平比较差异无统计学意义(P〉0.05)。(3)血清IL-32水平与IL-6水平呈正相关(r=0.70,P〈0.05)。结论 (1)乙型肝炎患者外周血IL-32、IL-6水平升高,且随炎症程度加重呈上升趋势,推测IL-32、IL-6可能在炎症反应中发挥重要作用,IL-32、IL-6参与了乙型肝炎患者肝组织损伤及病情发展的过程。(2)血清IL-32、IL-6水平变化与HBV复制水平无关。 相似文献
