BACKGROUND: Microsurgical operation might fail due to trauma-induced hypercoagulability.OBJECTIVE: To observe the changes of polymerization of fibrin monomer after the treatment of trauma so as to explore an effective means for assisting the prediction of post-traumatic hypercoagulability and thrombosis.DESIGN: Case-control observation and self-control study.SETTING: Institute of Thrombus and Hemostasis, the Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.PARTICIPANTS: Totally 34 traumatic patients were included from those who were admitted to the Union Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology, between May 2001 and January 2002. There were 18 males and 16 females aged 8-65 years old. Another 96 healthy people, 50 males and 46 females aged 21-68 years old, who came for routine physical examination were enrolled as normal controls. The history of coagulation impairment, and general and coagulation-related diseases were excluded in all the subjects.METHODS: Polymerization of plasmic fibrin monomer was detected. Fibrinogen would transform into fibrin monomers and display polymerization induced by acutobin. The accompanied changes of the turbidity were dynamically monitored using spectrophotometer at 340 nm; the obtained electrical signals were then input into the computer for statistical analysis. Venous blood samples were collected from traumatic patients immediately after hospitalization and on the 3rd day after the treatment with clinical debridement, surgery, sutures, liquid supplement and administration of antibiotics to determine polymerization of fibrin monomer. MAIN OUTCOME MEASURES: ① The rate of polymerization of fibrin monomer (taken as the comprehensive predictor for the concentration and function of plasmic fibrinogens). ② Maximum absorbency (reflecting the amount of coagulable plasmic fibrinogen in blood specimen). ③ The ratio between the rate of polymerization of fibrin monomer and maximum ab sorbency (reflecting the polymerization of plasmic fibrinogen molecules). RESULTS: All participants completed the corresponding examinations and were brought into data analysis. ① In traumatic group, the rate of fibrin monomer polymerization, the content of fibrinogen, the ratio of polymerization rate to maximum absorbency were all significantly higher than those in normal control group [traumatic group: 0.87±0.31, (5.81±3.22) g/L,4.61±0.97; normal control group: 0.61±0.15, (3.36±1.02) g/L, 3.93±0.68,P < 0.01]. ② At treatment of 3 days, although the rate of polymerization and the content of fibrinogen were found slightly declined, they were still higher than those in normal group [3.93±0.68, (4.21±1.93) g/L]; however,the ratio of polymerization rate to maximum absorbency did not change after treatment (4.68± 1.19).CONCLUSION: The content and function of fibrinogen would increase in traumatic patients. Traumatic patients display hypercoagulability characteristics and have thrombosis tendency. Determining the polymerization of fibrin monomer can be taken as an effective means for assisting the prediction of posttraumatic hypercoagulability and thrombosis.

BACKGROUND: The elevation of plasma fibrinogen(Fbg) is a key risk factor of cerebrovascular diseases. The evaluation of the monomer polymerization function of fibrin has even more important clinical merit than the detection of Fbg level.OBJECTIVE: To investigate the clinical significance of the monomer polymerization function of fibrin in patients with isehemie cerebrovascular diseases and its impacts on rehabilitative intervention.DESIGN: A case control study employing patients and healthy individual as subjects.SETTING: An Institute of Hematology and Department of Neurology of one university.PARTICIPANTS: Totally 110 patients with different ischemic cerebrovascular disease selected from the Department of Neurology, Union Hospital of Tongji Medical College, Huazhong Science and Technology University from September 2001 to March 2002, and 50 healthy individuals were included in the study.METHODS: Rehabilitative intervention was performed in 31 randomly selected cerebral infarct patients, and the parameters indicating the monomer polymerization functions of fibrin in the plasma were detected by the measurement system for the monomer polymerization function of fibrin.MAIN OUTCOME MEASURES: Abnormal condition of monomer polymerization function of fibrin in each parameter.RESULTS: Each parameter indicating the monomer polymerization functions of fibrin in plasma was significantly increased in ischemic cerebrovascular diseases patients than healthy individuals( P < 0.01 ) . The abnormal rate of Fbg leveland fibrin monomer polymerization velocity (FMPV) was significantly elevated in ischemic cerebrovascular disease patients than healthy individuals ( P < 0. 01 ) . The relative risk(RR) of ischemic cerebrovascular diseases in patients with abnormal FMP functions was 4 to 31 times more than healthy control group. In cerebral infarct group, FMPV of anterior circulation infarct subgroup was significantly elevated than that of posterior circulation infarct and lacunar cerebral infarct subgroups( P < 0.05). The FMP function of anterior cerebral infarct patients was significantly higher than that of healthy group before rehabilitative intervention. Although each FMP parameter reduced after rehabilitative intervention, the difference between was not significant compared with that of before therapy.CONCLUSION: FMP function analysis can completely and objectively reflect the coagulation status of the patients with ischemic cerebrovascular diseases, and it can also reflect the range and severity of infarct to some extent. Although common rehabilitative intervention cannot effectively improve the high-coagulation of the blood, the impacts of specific rehabilitative intervention on the coagulation mechanism deserve further investigation.

The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P = 0.005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0.039). There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r = -0.41, P = 0.003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r = 0.314, P = 0.023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10 and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.
