Chinese Journal of Postgraduates of Medicine 2009;32(7):11-13
Objective To investigate the coagulation and fibrinolytie system changes in liver cirrhosis (LC) patients with and without portal vein thrombosis (PVT). Method Twenty-six cases of LC with PVT (PVT group) and 61 eases of LC without PVT (control group) were chosen. Platelet(Pt), prothrpmbin time (PT), activated partial thromboplastin time (APTT), fibrin (Fib), D-dimer, tissue plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-l) were determined. SPSS 11.5software was used for statistic analysis. Results In PVT group, the average level of D-dimer was (0.97±0.53 ) mg/L,signifieantly higher than that in control group (0.61±0.40) mg/L. No significant difference was found between the two groups in Pt PT, APTT, Fib, t-PA and PAI-1. PT and APTT were progressively prolonged from Child-Pugh grade A to B and then to C. Fib was progressively decreased from Child-Pugh grade A to B and then to C. Decreased Pt and increased t-PA, PAI-1 were found in LC patients, but had no sighifieant difference. Conclusions The changes determined of coagulation and fibrinolytie system in patients with LC are abnormal. The average level of D-dimer is higher in LC patients with PVT than that in LC patients without PVT. D-dimer may be a helpful tool to rule out the presence of an underlying PVT in LC patients.

Objective To investigate the relationship of thyroid hormone (TH), thyroid stimulating hormone (TSH) and blood calcium in hyperlipidemic acute pancreatitis (HLAP) patients. Methods Fifty patients with HLAP were selected, among whom 37 patients with mild acute pancreatitis (MAP) were enrolled into MAP group, and 13 patients with moderately severe acute pancreatitis (MSAP) were enrolled into MSAP group. The albumin, blood glucose, creatinine, blood lipids, blood calcium, free tri-iodothyronine (FT3), free thyroxine (FT4) and TSH levels were measured and analyzed. Results The blood calcium, FT3 and TSH levels in MAP group were significantly higher than those in MSAP group:(2.02 ± 0.26) mmol/L vs. (1.75 ± 0.27) mmol/L, (1.88 ± 0.46) ng/L vs. (1.52 ± 0.35) ng/L and (0.28 ± 0.20) mU/L vs. (0.17 ± 0.12) mU/L, but the blood glucose and triglycerides (TG) levels were significantly lower than those in MSAP group: (13.36 ± 5.83) mmol/L vs. (19.99 ± 7.97) mmol/L and (24.01±12.46) mmol/L vs. (34.76 ± 20.39) mmol/L, and there were statistical differences (P<0.01 or<0.05). There were no statistical differences in albumin, creatinine, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol (LDL-C) and FT4 levels between 2 groups (P>0.05). The correlation analysis result showed: in patients with HLAP, TSH and albumin had a positive correlation with blood calcium (r=0.344 and 0.372, P=0.014 and 0.008), LDL-C and TG had negative correlation with blood calcium (r=-0.315 and-0.444, P=0.026 and 0.001), and other indexes had no correlation with blood calcium (P>0.05). Conclusions Blood calcium, FT3 and TSH levels are decreased with severity of HLAP. Decreased blood calcium may be one of reasons for decreased TSH in HLAP patients.

Objective To investigate the relationship between thrombomodulin(TM), fibrinolytic system changes and the score of the model for end-stage liver disease(MELD)in liver cirrhosis patients.Methods Eighty-five liver cirrhosis patients admitted from January 2008 to December 2009 were included in this study. TM, D-dimer, tissue plasminogen activator(t-PA), plasminogen activator inhibitor -1(PAI-1),serum creatinine, serum total bilirubin and international normalized ratio(INR)on all patients were measured and then the score of the MELD was calculated. Results The score of the MELD was 1-29(11.35 ± 6.02)scores. The score of the MELD ≤ 9 scores was 40 cases(47.1%), 10- 19 scores was 32 cases (37.6%),20-29 scores was 13 cases(15.3%).TM and D-dimer were progressively increased with MELD score. There was significant difference among the three groups(P<0.01). The levels of TM and D-dimer had positive correlation with the score of the MELD(r = 0.706,0.425,P < 0.01). Conclusions The levels of TM and D-dimer have positive correlation with the score of the MELD in liver cirrhosis patients. These indices can help predicting the degree of liver function disorder and prognosis.
