The study was aimed to observe the changes of blood coagulation factors in the SD rats suffered from hemorrhagic shock, and to investigate the mechanism of coagulation cascade reaction in the course of shock. The model of hemorrhagic shock was established. 40 SD rats were randomized into eight groups: pre-shock, and 1, 2, 4, 6, 8, 12 and 24 hours after shock, and the levels of plasma FVIII, vWF, TF, D-dimer, FIB, APTT and PT were detected respectively. The result showed that APTT and PT were gradually prolonged, which were significant within 4-6 hour after shock (P < 0.05). APTT and PT were 59.7 seconds and 30.2 seconds respectively. The level of plasma D-dimer markedly increased, and peaked at 8 hour after shock. The level of fibrinogen, TF, vWF and FVIIIa increased in the initial stage of shock. With the development of shock, fibrinogen markedly reduced from 2nd hour (P < 0.05) and dropped to the minimum at 7 hours after shock. Plasma TF, vWF, FVIII significantly decreased after 6 hours and 8 hours (P < 0.001). The ratios of the consumed coagulation factors: FVIII of (86.1 +/- 1.8)%, fibrinogen of (89.6 +/- 0.6)%, vWF (55 +/- 1.4)%, TF (62 +/- 2.5)%. Thus, coagulation factor I (fibrinogen) and FVIII were preferentially consumed. The extrinsic coagulation pathway was dominantly activated, whereas the intrinsic coagulation pathway played a less important role. Fibrinogen and D-dimer might be valuable for the prognosis of patients suffered from shock. It is concluded that hemorrhagic shock trigger the coagulation cascade reaction, and the coagulation factors are greatly consumed. Unbalance of coagulation system plays an important role in the progress of shock.

OBJECTIVETo investigate the blood fibrinogen (FIB) content before and after chemotherapy or radiotherapy in 43 malignant tumor patients.

METHODSCOULTER ACL-200 automated coagulation analyzer was used in monitoring FIB in the patients.

RESULTSThe FIB content was significantly higher in malignant tumor patients than that in benign disease patients. Significant reduction was observed after treatment which became elevated again when there was recurrence or metastasis.

CONCLUSIONAssessment of FIB not only helps to diagnose cancers but evaluate the therapeutic effect and prognosis also.

OBJECTIVETo preliminarily explore the relationship between thrombosis and its associated factors in patients with coronary heart disease (CHD) of turbidity-phlegm blocking syndrome (TPB), and to study its acting mechanism.

METHODSPlasma levels of thrombosis-associated factors, including Von Willebrand factor: (vWF), D-dimer, and fibrinogen (Fg), in 85 patients of CHD with TPB, 93 with CHD of non-TPD, and 89 healthy persons were detected and compared.

RESULTSLevels of the three factors were increased in all the CHD: patients, and were higher in TPB patients than in non-TPB patients (P<0.01 or P<0.05).

CONCLUSIONThe TPB: syndrome in CHD patients was closely related to the blood coagulation-fibrinolytic system; they might be in pre-thrombosis state, and the plasma levels of vWF, D-dimer, and Fg could be taken as the objective indices for thrombosis differentiation of TPB syndrome in CHD patients.

OBJECTIVETo investigate the correlation of tongue manifestation with the fibrinogen level and the neutrophil count in blood of acute cerebral infarction patients.

METHODSA total of 200 patients with first unilateral cerebral infarction in Neurology Department of Xuanwu Hospital from March, 2008 to February, 2009 were recruited in this study. The correlation of the tongue fur color and texture with the blood fibrinogen level and the neutrophil count was analyzed in these patients.

RESULTSThe level of fibrinogen and neutrophil count in thick fur group were significantly higher than that in thin fur group (P<0.05). There was no statistical difference in the level of fibrinogen and neutrophil count found between moist fur and dry fur. Statistical significance existed in the level of fibrinogen between the greasy tongue fur group and non-greasy tongue fur group (P<0.05). The level of fibrinogen and the neutrophil count were compared among different fur color groups, revealing that the level of fibrinogen in yellowish fur group was higher than that of white fur group and normal value with statistical significance (P<0.05) with neutrophil count in yellowish fur group being significantly higher than that in white fur group.

CONCLUSIONOur results suggested that the change of tongue manifestation was associated with the level of fibrinogen and the neutrophil count in the blood of cerebral infarction patients.

OBJECTIVETo compare changes of blood clotting state after initial trauma fractures and twice trauma fractures, investigate the effect of fracture history to the state of the blood clotting after secondary trauma fractures.

METHODSThirty New Zealand rabbits were selected, aged 5-6 months, males and females unlimited, weighted 2.4-2.6 kg, non-pregnant. Postoperative model of initial trauma fractures was established, and then postoperative model after twice trauma fractures was built. Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fiber fibrinogen (FIB) and D-dimer (DD) were detected by venous blood at 1 day and 5 days after surgery. Changes of indicators were compared between after twice fractures at the same time.

OBJECTIVETo determine the changes in levels of D-dimer, prothrombin time (PT), fibrinogen (Fib), CD4 and CD8 in relation to hepatopulmonary syndrome (HPS) by using a rat model system and to assess the association with pathologic changes in lung.

METHODSForty male Sprague-Dawley rats were divided into equal groups for modeling of cirrhosis and HPS. The two groups were assessed by blood gas analysis, standard biochemical tests to measure D-dimer, PT, Fib, CD4 and CD8, and pathological examination of lung tissues.

RESULTSThe HPS rats showed significantly lower PaO2 than the cirrhosis rats (58.20+/-3.19 mmHg vs. 85.00+/-2.53 mmHg, P = 0.000). The HPS rats showed significantly higher levels of D-dimer, Fib and CD8 than the cirrhosis rats (0.39+/-0.09 mg/ml vs. 0.25+/-0.05 mg/ml, P = 0.000; 1.77+/-0.10 g/L vs. and 1.49+/-0.09 g/L, P = 0.010; 32.32+/-4.45/mm3 vs. 20.13+/-6.09/mm3, P = 0.014). The HPS rats showed significantly lower levels of PT, CD4 and CD4/CD8 than the cirrhosis rats (14.86+/-1.04 s vs. 16.23+/-0.75 s, P = 0.036; 20.45+/-3.86/mm3 vs. 26.75+/-5.32/mm3, P = 0.000; 0.64+/-0.09 vs. 1.32+/-0.13, P = 0.000). The lung tissues of the HPS rats showed microthrombosis in pulmonary vessels, which were not observed in lung tissues of the cirrhosis rats.

CONCLUSIONHPS-related differential levels of D-dimer, PT, Fib, CD4, CD8 and CD4/CD8 may represent a biomarker profile suggestive of incidence of thromboembolism in lung.

OBJECTIVETo detect hFgl2 expression in peripheral blood mononuclear cells in patients with chronic hepatitis B and liver cancer and explore its association with the severity of chronic hepatitis B.

METHODSThe protein expression of hFgl2 in peripheral blood mononuclear cells was detected in 78 patients with chronic hepatitis B (including mild, moderate, or severe cases), chronic severe hepatitis, or liver cancer, with 20 healthy volunteers as controls. The data were analyzed in comparison with the patients' alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBiL and) levels.

RESULTShFgl2 protein expression was significantly higher in patients with chronic severe hepatitis and liver cancer than in the healthy volunteers and patients with chronic hepatitis B. The patients with chronic severe hepatitis had significantly higher hFgl2 protein expression than patients with liver cancer. In severe cases of chronic hepatitis B, hFgl2 protein expression was positively correlated with ALT, AST and TBiL, but these correlations were not found in mild or moderate cases.

CONCLUSIONSPeripheral blood mononuclear cells express hFgl2 protein, whose expression level increases with the severity of chronic hepatitis B.
