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.

RESULTSComparing with 1 day after the secondary trauma fracture and initial trauma fracture surgery, PT, APTT values showed no significant difference (P > 0.05), TT, FIB, DD values were increased, and the difference was statistically significant (P < 0.05); Comparing with 5 days after the secondary trauma fracture and initial trauma fracture surgery, PT values showed no significant difference (P < 0 .05), APTT, TT, FIB, DD values were increased, and the difference was statistically significant (P< 0.05).

CONCLUSIONBlood after the secondary trauma fractures is in hypercoagulable state after fracture surgery.

AIMTo investigate the anticoagulant efficacy and mechanism of a semi-synthesized sodium beta-1,4-glucan sulfate (Na-MCS).

METHODSAnticoagulant activity was evaluated by means of coagulation assays in comparison with heparin. The anticoagulant mechanism of Na-MCS was disclosed by inhibitory analysis of the activities of coagulation factors using chromogenic substrates.

RESULTS0.6 microg x mL(-1) Na-MCS could significantly prolong APTT and TT, but has less effect on PT at an even higher concentration. The dosage of Na-MCS required to double APTT of normal human plasma was 0.7 microg x mL(-1), lower than that of heparin with the activity of 150 u x mg(-1).

CONCLUSIONNa-MCS represented a potent anticoagulation activity in vitro, which matched the efficacy of heparin in a certain range of concentrations. Na-MCS exhibited anticoagulant activity due to inhibition of the coagulation factors IIa and Xa by the mediation of anti-thrombin AT-III.

The purpose of this study was to investigate the effects of training on prothrombin time, activated partial thromboplastin time, and fibrinogen (Fb) concentrations in horses to assess potential adaptive response to training. Fifteen clinically healthy horses were enrolled in the present study and equally divided into three groups. Group A completed an intense training program, group B participated in a light training program, and group C included sedentary horses. After 5 weeks, group B was subjected to the same training program completed by group A and renamed group B1. Blood samples were collected by jugular venipuncture from each animal at rest and analyzed within 2 h after sampling. A two-way ANOVA for repeated measures showed a significant effect of training (p < 0.05) on Fb concentrations in group B1 alone during the first week after changing the training program. Our findings demonstrated that Fb is a parameter susceptible to training. Fb plasma levels increase with a more intense training program. However, Fb plasma levels decreased after the first week and returned to basel levels, suggesting that the horses had adapted to the new training program.

BACKGROUNDTo investigate the prognostic significance and role of coagulation factor V (CFV) levels in clinical diagnostic criteria for severe hepatitis.

METHODSThe CFV level and prothrombin activity (PTA) were tested by turbidimetry for 129 times in 58 patients with severe hepatitis. Comparative studies and clinical significance of CFV and PTA were analyzed by SPSS and SDAS softwares.

RESULTS1. The levels of CFV and PTA were 15.3%+/-9.7% and 23.5%+/-10.0%, respectively, at the onset of severe hepatitis. 2. The mortality of severe hepatitis gradually increased with the gradual decrease of CFV or PTA during the most severe stage of the illness (P=0.000). 3. The levels of CFV and PTA decreased continually and rapidly in patients who died but gradually increased in survivors. The decrease or increase of PTA preceded that of CFV on the exacerbation or convalescent stage. 4. Hepatic encephalopathy occurred in 14 cases (24.14%). In 10 cases, it occurred in the terminal stage of the illness, far later than the time of the decrease of CFV. 5. The level of CFV was closely related to PTA (the correlation coefficient was 0.812), the level of CFV was almost consistent with that of PTA.

CONCLUSION1. The level of CFV is an important prognostic indicator in severe hepatitis and is more specific than PTA. 2. Simultaneous determination of CFV and PTA may be helpful in earlier and more accurate diagnosis of severe hepatitis. 3. Possible use of CFV as one of the criteria for liver transplantation in patients with severe hepatitis should be studied.

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.

BACKGROUND AND OBJECTIVEPatients with malignant tumor are at high risk of thrombophilia, which contributes to thromboembolism. Surgical treatment is one of the critical risk factors. In this study, changes and clinical significances of blood coagulation of lung cancer patients pre- and post operation were investigated.

METHODSA prospective, controlled study were carried out in 74 lung disease patients, who were divided into lung cancer group and benign lung disease group. In each group, pre- and postoperative changes in prothrombin time (PT), activated partial thromboplastin time (APT), platelet count (PLT), D-dimer (D-D) and fibrinogen (Fib) and clinical performances were observed and compared in intra- and intergroups.

RESULTSThe concentration of Fib both in lung cancer group and its subgroup (adenocarcinoma of lung) increased, preoperative differences between benign lung disease group and subgroup (squamous cell carcinoma of lung) was significant (P < 0.05). PT (postoperative 1st to 7th day) in lung cancer group prolonged, APTT (postoperative 3rd to 7th day) reduced, Fib (postoperative 3rd to 7th day) and D-D (postoperative 1st to 7th day) increased, PLT reduced on the 1st, 3rd day but then increased on the 5th, 7th day after operation, the difference between pre- and post-operation was significant (P < 0.05). D-D and PT in lung cancer group on the 7th day was longer than in benign lung disease group (P < 0.05). One pulmonary thromboembolism (PTE) case in lung cancer group occurred, while in benign lung disease group none venous thromboembolism (VTE) appeared.

CONCLUSIONPatients with lung cancer are in high hypercoagulable state, and prone to VTE. It is necessary to take some interventions to avoid VTE.
