<p><b>OBJECTIVE</b>To study the relationship between the change of coagulation and the clinicopathologic characteristics in patients with gallbladder cancer.</p><p><b>METHODS</b>The 64 gallbladder cancer patients (GBC group) and 60 cholecystitis patients (control group) had been reviewed from January 2007 to June 2013. The prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), and thrombin time (TT) had been measured and compared between patients of GBC group and control group. The relationship of coagulation function and prognosis were analyzed.</p><p><b>RESULTS</b>Compared with control group, APTT in GBC group ((29.0 ± 4.2) s) was significantly shortened (t = -4.265, P = 0.000) and PT ((11.5 ± 1.4) s), TT ((15.3 ± 3.5) s), Fib ((4.1 ± 0.9) g/L) were significantly increased in GBC group (t = 2.521, 4.147 and 4.365, all P < 0.05). The level of Fib was higher in patients with medium or poor-differentiated tumor cells (F = 4.069, P = 0.022), lymph metastasis (t = 2.640, P = 0.010) and advanced staging (II-IV) (t = 3.003, P < 0.01) than those of well-differentiated, non-lymph metastasis and early staging (0-I). The ratio of gallbladder cancer with hyperfibrinogenemia (32/64) was significantly higher than control group (11/60, χ(2) = 13.709, P < 0.01). In GBC group, compared with normal Fib patients, hyperfibrinogenemia patients showed significantly difference in clinicopathologic characteristics (χ(2) = 5.851-10.573, P < 0.05). The average survival period of hyperfibrinogenemia patients and normal Fib patients were 8.63 months and 16.73 months. The 1-, 3-year survival rate of patients with hyperfibrinogenemia were significantly lower than those with normal Fib (64.7%, 14.9% vs. 74.9%, 21.1%, P < 0.05).</p><p><b>CONCLUSION</b>Preoperative plasma level of Fib might be a new promising biomarker in patients with gallbladder cancer for evaluating disease progression and prognosis.</p>

<p><b>OBJECTIVE</b>To investigate the expression of perforin and granzyme B in rejection response following liver transplantation, and evaluate their roles to be used as predictive markers of rejection.</p><p><b>METHODS</b>The expression of perforin and granzyme B in liver biopsies obtained from liver allograft recipients was determined by immunohistochemistry. Biopsies were classified into two groups-no evidence of rejection and rejection-according to Histopathologic criteria. The relationship between the perforin/granzume B expression and acute rejection was analyzed.</p><p><b>RESULTS</b>From 19 patients, thirty-five liver biopsies were obtained after liver transplantation. Among them, nineteen samples were diagnosed as rejection response. The frequencies of perforin and granzyme B expression in rejection group were 100% (19/19) and 94.7% (18/19), respectively. While those in no rejection group were 25.0% (4/16) and 12.5 (2/16), respectively. In most rejected samples, perforin and granzyme B were expressed simultaneously. Only three samples showed perforin expression alone, while no samples demonstrated granzyme B expression alone. There was a close relationship between perforin/granzyme B expression and liver allograft rejection.</p><p><b>CONCLUSION</b>Perforin and granzyme B expression seemed to be related to the development of acute rejection following liver transplantation, and might be served as sensitive and reliable markers in diagnosing acute rejection in early stage.</p>
