Objective: To investigate the effect of severe heatstroke on coagulation function in rats and the possible mechanism of high-mobility group protein B1(HMGB1)involved in the regulation of coagulation function. Methods:...Objective: To investigate the effect of severe heatstroke on coagulation function in rats and the possible mechanism of high-mobility group protein B1(HMGB1)involved in the regulation of coagulation function. Methods: A total of 24 male SD rats were randomly divided into control group, mild group, moderate group and severe group,with 6 rats in each group. The rats in mild group, moderate group and severe group were continuously exposed to 40℃ and 10% humidity environment, then taken out and rewarmed to complete the heat stroke rat modeling process after the experiments were conducted for 70, 110, and 145 min, respectively. The levels of HMGB1 in peripheral blood were detected by enzyme-linked immunosorbent assay(ELISA) before modeling and at 0 and 3 h after modeling, and coagulation tests were used to determine prothrombin time(PT), activated partial thromboplastin time(APTT), and prothrombin time(APT) at the same time points in the rats. The correlation between HMGB1 and coagulation parameters was determined by Pearson correlation. Results: In the severe group, HMGB1 was(2372.45±97.85) pg/ml and(2547.72±117.67) pg/ml at 0 and 3 h after modeling, respectively, and the levels of PT, APTT and Fib were higher than those before modeling and at 3 h after modeling. There was significant correlation between HMGBI and APTT, Fib(r=0.978, 0.785, P=0.000, 0.000). There were positive correlations between HMGBI and PT, APTT, Fib(r=0.634,0.976,0.889, P=0.001,0.000,0.000).Conclusion: HMGB1 may be involved in the pathogenesis of coagulation dysfunction in rats with severe heatstroke by regulating the activation of coagulation cells, and the level of HMGB1 in rats with severe heatstroke increases and still tends to increase after rewarming.展开更多

Heparin is still used commonly for PCI, but the bleeding complications is high. However, Bivalirudin is similar to heparin in ischemic complications and superior to the bleeding complica- tions. Methods A total of 181 patients with coronary artery disease and renal insufficiency were randomly as- signed two treatment groups： Bivalirudin （n = 90）, unfractionated heparin （n = 91）. Activated clotting time （ACT） was determined in patients at 5 min after undergoing PCI at the end of operation immediately （stopping drug im- mediately） , and 30 min,1 h, 2 h after stopping drug. Activated partial thromboplastin time （APTT）, thrombin time （TT）, proth rombin time （PT）, fibrinogen （FIB） index were measured before treatment, 6 h, 24 h and 72 h af- ter the treatment through an automated coagulation analyzer. Platelet count was monitored before treatment and 24 h after treatment. The end points were the proportion of net adverse clinical events （NACE） and stent throm- bosis at 30 days. Results The use of bivalirudin was associated with a statistically significant higher at 5 min af- ter treatment, end of operation immediately （P 〈 0.05）, with statistically significant lower at lh after stopping drug , 2h after stopping drug （P 〈 0.05）. There were no differences between patients at blood coagulation and platelet after operation （P 〉 0.05）, no differences in the 30-day rates of stent thrombosis （0% vs. 0%, P = 1）. Elev- en patients（12.22%） treated with bivalirudin vs. 24 （26.38%） treated with heparin experienced an adverse clinical events at 30 days （relative risk[RR], 0.46; 95%CI, 0.36-0.56; P 〈 0.025）. There were no differences in the major adverse cardiac or cerebral event at the 30-day end point（1.11% vs. 2.20%, P 〉 0.05）. The bleeding at 30 days was abated by using bivalirudin compared with unfracfionated heparin （11.11% vs. 24.18%, P 〈 0.05）. Conclu- sions Compared with the unfractionated heparin, bivalirudin is more quickly in taking effect and recovering and more efficient for PCI in patients with coronary artery disease and renal insufficiency.展开更多

Most patients are in the middle and late stage when diagnosed, and its high mortality and poor prognosis have seriously threatened the health and life. Fibrinogen (FIB) is mainly used as a coagulation factor in the body to participate in the process of coagulation and haemostasis, and is the main protein in the coagulation process. In recent years, studies at home and abroad have shown that FIB levels correlate with the diagnosis, outcome prediction and prognosis of CRC, and some of the findings are still controversial. This article aims to review the related research and new progress of the relationship between FIB and CRC in recent years.展开更多

Venous blood samples were collected by routine venipuncture. Eighty-five patients were divided into two groups according to diagnostic criteria of SIRS： SIRS patients from intensive care units （n=50）, and non- SIRS patients from medical wards （n=35）. Thirty healthy blood donors who visited the General Health Check-up Division at Wuhan Central Hospital served as controls. Excluded from the study were （1） those patients with pregnancy; （2） those with cancer; （3） those died after admission into the ICU in 7 days; （4） those received cardiopulmonary resuscitation; （5） those who had previous blood system diseases; and （6） those with SIRS before admission into the ICU. The levels of uPA, uPAR, D-D, IL-6 and TNF-a in blood were detected by commercial enzyme-linked immunosorbent assay （ELISA） kit. The data were analyzed using SPSS version 17.0 and expressed as mean ＋ standard. Student＇s t test and the Mann-Whitney U test were used in the analysis. The relations of uPA, uPAR and D-dimer, IL-6 TNF-α levels were analyzed using Spearman＇s rank-order correlation coefficient test. RESULTS： The plasma levels of uPA, uPAR, D-dimer, lL-6 and TNF-α in the patients with SIRS were obviously higher than those in the non-SIRS patients and controls （P〈0.001）. Correlation analysis showed a positive correlation between uPAR and IL-6 levels （r=0.395, P=0.004） and between uPAR and TNF-a levels （r=0.606, P〈0.001）, but no correlation between uPAR and D-dimer levels （r=0.069, P=0.632）. No correlation was observed between uPA, D-dimer, IL-6 and TNF-α levels （P〉0.05）. The establishment of ROC curve was based on the levels of uPAR, D-dimer, IL-6 and TNF-α in 24 hours for the diagnosis of multiple organ dysfunction syndrome （MODS）, and the ROC areas under the curve were 0.76, 0.58, 0.86 and 0.83, respectively. CONCLUSIONS：uPA and uPAR play a major role in patients with SIRS in the process of coagulation disorder, but the mechanism of SIRS is not the same. uPAR may play a central role in the development of SIRS to MODS.展开更多

The same parameters were compared with those of 15 control subjects,who had no detectable heart disease,but with paroxysmal supraventricular tachycardia undergoing radiofrequency catheter ablation of the left accessory pathway through a transseptal passage. Results Blood from the left atrium contained an excessive amount of platelet activity,thrombin generation and fibrinolysis compared with the blood from the right atrium,and the femoral veins and arteries. However blood from the right atrium was much lower in these activities when compared with those from the left atrium,and the femoral veins and arteries in both groups. Compared with those in the control subjects, GMP-140 in the left atrium was significantly higher ( P <0.05) and AT Ⅲ was significantly lower ( P <0.05) in patients with MS. Compared with the patients with MS and spontaneous left atrial echocontrast (LASEC)≤1,the patients with MS and LASEC≥2 had significantly higher levels of GMP-140 in plasma ( P <0.05),and significantly lower levels of AT Ⅲ ( P <0.05) and PC ( P <0.01) levels in the left atrium. However, there were no significant differences between patients with atrial fibrillation and those with sinus rhythm regarding amounts of plasma coagulation markers in the left atrium. Univariate regression analysis revealed that LASEC was negatively correlated with plasma levels of blood from the left atria in the patients with MS. Conclusion Coagulability is increased in the left atria of patients with MS and is positively correlated with LASEC.展开更多

文摘Objective: To investigate the effect of severe heatstroke on coagulation function in rats and the possible mechanism of high-mobility group protein B1(HMGB1)involved in the regulation of coagulation function. Methods: A total of 24 male SD rats were randomly divided into control group, mild group, moderate group and severe group,with 6 rats in each group. The rats in mild group, moderate group and severe group were continuously exposed to 40℃ and 10% humidity environment, then taken out and rewarmed to complete the heat stroke rat modeling process after the experiments were conducted for 70, 110, and 145 min, respectively. The levels of HMGB1 in peripheral blood were detected by enzyme-linked immunosorbent assay(ELISA) before modeling and at 0 and 3 h after modeling, and coagulation tests were used to determine prothrombin time(PT), activated partial thromboplastin time(APTT), and prothrombin time(APT) at the same time points in the rats. The correlation between HMGB1 and coagulation parameters was determined by Pearson correlation. Results: In the severe group, HMGB1 was(2372.45±97.85) pg/ml and(2547.72±117.67) pg/ml at 0 and 3 h after modeling, respectively, and the levels of PT, APTT and Fib were higher than those before modeling and at 3 h after modeling. There was significant correlation between HMGBI and APTT, Fib(r=0.978, 0.785, P=0.000, 0.000). There were positive correlations between HMGBI and PT, APTT, Fib(r=0.634,0.976,0.889, P=0.001,0.000,0.000).Conclusion: HMGB1 may be involved in the pathogenesis of coagulation dysfunction in rats with severe heatstroke by regulating the activation of coagulation cells, and the level of HMGB1 in rats with severe heatstroke increases and still tends to increase after rewarming.
文摘Background Renal insufficiency is associated with an excess risk of vascular complications and bleeding events in patients who undergo PCI. Heparin is still used commonly for PCI, but the bleeding complications is high. However, Bivalirudin is similar to heparin in ischemic complications and superior to the bleeding complica- tions. Methods A total of 181 patients with coronary artery disease and renal insufficiency were randomly as- signed two treatment groups： Bivalirudin （n = 90）, unfractionated heparin （n = 91）. Activated clotting time （ACT） was determined in patients at 5 min after undergoing PCI at the end of operation immediately （stopping drug im- mediately） , and 30 min,1 h, 2 h after stopping drug. Activated partial thromboplastin time （APTT）, thrombin time （TT）, proth rombin time （PT）, fibrinogen （FIB） index were measured before treatment, 6 h, 24 h and 72 h af- ter the treatment through an automated coagulation analyzer. Platelet count was monitored before treatment and 24 h after treatment. The end points were the proportion of net adverse clinical events （NACE） and stent throm- bosis at 30 days. Results The use of bivalirudin was associated with a statistically significant higher at 5 min af- ter treatment, end of operation immediately （P 〈 0.05）, with statistically significant lower at lh after stopping drug , 2h after stopping drug （P 〈 0.05）. There were no differences between patients at blood coagulation and platelet after operation （P 〉 0.05）, no differences in the 30-day rates of stent thrombosis （0% vs. 0%, P = 1）. Elev- en patients（12.22%） treated with bivalirudin vs. 24 （26.38%） treated with heparin experienced an adverse clinical events at 30 days （relative risk[RR], 0.46; 95%CI, 0.36-0.56; P 〈 0.025）. There were no differences in the major adverse cardiac or cerebral event at the 30-day end point（1.11% vs. 2.20%, P 〉 0.05）. The bleeding at 30 days was abated by using bivalirudin compared with unfracfionated heparin （11.11% vs. 24.18%, P 〈 0.05）. Conclu- sions Compared with the unfractionated heparin, bivalirudin is more quickly in taking effect and recovering and more efficient for PCI in patients with coronary artery disease and renal insufficiency.

文摘Background:Sepsis-induced coagulopathy and multiple organ dysfunction syndromes are the leading causes of death in patients with sepsis.Qingwen Baidu decoction(QWBD)can effectively improve the clinical manifestations of sepsis and ease inflammation,but its effects on coagulation functions and multiple organ injuries remain unclear.Methods:100 healthy,male Sprague-Dawley rats were randomly divided into the sham group,the cecal ligation and puncture(CLP)group,the low-dose QWBD group,and the high-dose QWBD group,with 25 rats in each group.The sepsis model was established using CLP.Blood was collected to measure platelet count,serum creatinine(Cr),blood urea nitrogen(BUN),alanine aminotransferase(ALT),and aspartate aminotransferase(AST)levels,as well as coagulation function.The total protein in bronchoalveolar lavage fluid(BALF)was determined in each group of rats.The lung,liver,and kidney tissues were harvested,and statistics were calculated on the wet-to-dry(W/D)weight ratio.Changes in histopathology and thrombin level were evaluated in each group.The remaining ten rats in each group were observed daily to record the number of surviving rats.Such observation was made consecutively for 7 days to calculate survival rates.Results:After model establishment,ALT,AST,Cr,and BUN levels were significantly elevated(P<0.01).The BALF protein content and lung W/D weight ratio were significantly increased(P<0.01).Furthermore,the survival rate of rats was significantly reduced in the CLP group compared with the sham group.After the treatment,rats in the high-dose QWBD group had lower ALT(P<0.05),AST(P<0.01),Cr(P<0.05),BUN(P<0.01)levels,lower BALF protein content(P<0.05)and lower lung W/D weight ratio(P<0.01)than the CLP group.However,rats in the high-dose QWBD group had significantly better pathological changes in the lung,liver,and kidney compared to the sham group.After the treatment,the platelet level in the peripheral blood was elevated(P<0.05)and both activated partial thromboplastin time and prothrombin time were significantly shortened(P<0.01).The fibrinogen level was significantly increased(P<0.01).Finally,thrombin positive expression areas in the lung,liver,and kidney were significantly decreased in the high-dose QWBD group.Conclusion:QWBD can improve coagulation disorders caused by sepsis and has a protective effect on multiple organ injuries in rats.
文摘Colorectal Cancer (CRC) is a common malignant tumour of the gastrointestinal tract in China, with increasing morbidity and mortality rates year by year. Most patients are in the middle and late stage when diagnosed, and its high mortality and poor prognosis have seriously threatened the health and life. Fibrinogen (FIB) is mainly used as a coagulation factor in the body to participate in the process of coagulation and haemostasis, and is the main protein in the coagulation process. In recent years, studies at home and abroad have shown that FIB levels correlate with the diagnosis, outcome prediction and prognosis of CRC, and some of the findings are still controversial. This article aims to review the related research and new progress of the relationship between FIB and CRC in recent years.
文摘BACKGROUND Obstetric hemorrhage is the leading cause of maternal mortality globally,especially in China.The key to a successful rescue is immediate and rapid blood transfusion.Autotransfusion has become an integral part of clinical blood transfusion,with intraoperative cell salvage(IOCS)being the most widely used.AIM To investigate the application of IOCS in cesarean section.METHODS A total of 87 patients who underwent cesarean section and blood transfusion in our hospital from March 2015 to June 2020 were included in this prospective controlled study.They were divided into the observation(43 cases)and control(44 cases)groups using the random number table method.The patients in both groups underwent lower-segment cesarean section.The patients in the control group were treated with traditional allogeneic blood transfusion,whereas those in the observation group were treated with IOCS.Hemorheology[Red blood cell count,platelet volume,and fibrinogen(FIB)]and coagulation function(partial prothrombin time,prothrombin time(PT),platelet count,and activated coagulation time)were measured before and 24 h after transfusion.In the two groups,adverse reactions,such as choking and dyspnea,within 2 h after cesarean section were observed.RESULTS Before and after transfusion,no significant differences in hemorheology and coagulation function indices between the two groups were observed(P>0.05).About 24 h after transfusion,the erythrocyte count,platelet ratio,and FIB value significantly decreased in the two groups(P<0.05);the PLT value significantly decreased in the two groups;the activated partial thromboplastin time,PT,and activated clotting time significantly increased in the two groups(P<0.05);and no statistical differences were observed in hemorheology and coagulation function indices between the two groups(P>0.05).Furthermore,there was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).CONCLUSION In patients undergoing cesarean section,intraoperative cell salvage has a minimum effect on hemorheology and coagulation function and does not increase the risk of amniotic fluid embolism.
文摘BACKGROUND Multiple myeloma patients usually present with CRAB symptoms(hypercalcemia,renal disease,anemia and bone diseases)as initial manifestations.Bleeding symptoms are less common,most of which result from thrombocytopenia or infiltration of plasmacytoma.Relatively,coagulopathy is not so common,especially isolated coagulopathy without CRAB manifestations,which is very rare.Herein,we report a 54-year old female who was hospitalized for intermittent and recurrent mild oral mucosal hemorrhage without other bleeding symptoms for almost one month or typical myeloma features.CASE SUMMARY Two months before admission,the patient underwent implantation of a permanent pacemaker due to sick sinus syndrome.Prothrombin time and activated partial thromboplastin time were significantly prolonged.Factor X deficiency was demonstrated to account for the coagulation dysfunction.An M protein peak was shown by serum protein electrophoresis.26.11%of abnormal plasma cells were detected in bone marrow by flow cytometry,expressing CD38,CD138,CD56 and intracellular immunoglobulin Kappa light chain.Bone marrow biopsy also proved the presence of abnormal plasma cells,but Congo red stain was negative.The patient was finally diagnosed with multiple myeloma IgA-κtype.A literature review indicated that factor X deficiency was highly related to amyloidosis.Before bleeding signs,the patient had cardiac arrhythmia,enlargement of the heart,and progressive heart failure;thus,cardiac amyloidosis was suspected.CONCLUSION Bleeding related to coagulation dysfunction is uncommon in multiple myeloma,especially as the initial manifestation.Amyloidosis is a well-recognized cause of isolated acquired factor X deficiency.

文摘We here aimed to investigate the impact of gender on the clinical characteristics and laboratory results of patients with coronavirus disease 2019(COVID-19)and provide clues to the pathological mechanisms underlying COVID-19.A retrospective study was performed.Clinical characteristics,severity of lung infection,laboratory results,and prognoses of patients of different gender were analyzed.A total of 242 patients were finally included.The median age was 58 years(IQR:40-68),including 54(22.3%)hospital staffs.Ninety-four(38.8%)were male and 148(61.1%)were female.The proportion of patients with diabetes was significantly higher in the male group than in the female group(P=0.034).Male patients had a significantly larger proportion of severe lung infection,higher leukocyte count,neutrophil count,neutrophil-to-lymphocyte ratio,C-reactive protein,and procalcitonin than femalc.Furthermore,male patients had worse liver,cardiac,and coagulation function than their female counterparts.Male patients with COVID-19 showed more severe inflammation reaction and coagulation dysfunction than female patients.In conclusion,gender is associated with host response to SARS-CoV-2 infection.
文摘BACKGROUND： This study aimed to determine the plasma levels of urokinase-type plasminogen activator （uPA）, urokinase-type plasminogen activator receptor （uPAR）, D-dimer, IL-6 and TNF-α, and observe the relations among uPA, uPAR, D-dimer, IL-6 and TNF-α in patients with systemic inflammatory response syndrome （SIRS）.METHODS： A prospective, clinical case-control study was conducted in patients with SIRS at age of more than 55 years old treated during 2008-2010 at Wuhan Central Hospital. Venous blood samples were collected by routine venipuncture. Eighty-five patients were divided into two groups according to diagnostic criteria of SIRS： SIRS patients from intensive care units （n=50）, and non- SIRS patients from medical wards （n=35）. Thirty healthy blood donors who visited the General Health Check-up Division at Wuhan Central Hospital served as controls. Excluded from the study were （1） those patients with pregnancy; （2） those with cancer; （3） those died after admission into the ICU in 7 days; （4） those received cardiopulmonary resuscitation; （5） those who had previous blood system diseases; and （6） those with SIRS before admission into the ICU. The levels of uPA, uPAR, D-D, IL-6 and TNF-a in blood were detected by commercial enzyme-linked immunosorbent assay （ELISA） kit. The data were analyzed using SPSS version 17.0 and expressed as mean ＋ standard. Student＇s t test and the Mann-Whitney U test were used in the analysis. The relations of uPA, uPAR and D-dimer, IL-6 TNF-α levels were analyzed using Spearman＇s rank-order correlation coefficient test. RESULTS： The plasma levels of uPA, uPAR, D-dimer, lL-6 and TNF-α in the patients with SIRS were obviously higher than those in the non-SIRS patients and controls （P〈0.001）. Correlation analysis showed a positive correlation between uPAR and IL-6 levels （r=0.395, P=0.004） and between uPAR and TNF-a levels （r=0.606, P〈0.001）, but no correlation between uPAR and D-dimer levels （r=0.069, P=0.632）. No correlation was observed between uPA, D-dimer, IL-6 and TNF-α levels （P〉0.05）. The establishment of ROC curve was based on the levels of uPAR, D-dimer, IL-6 and TNF-α in 24 hours for the diagnosis of multiple organ dysfunction syndrome （MODS）, and the ROC areas under the curve were 0.76, 0.58, 0.86 and 0.83, respectively. CONCLUSIONS：uPA and uPAR play a major role in patients with SIRS in the process of coagulation disorder, but the mechanism of SIRS is not the same. uPAR may play a central role in the development of SIRS to MODS.

文摘Objective To investigate the pathogenesis of thromboembolism in patients with mitral stenosis in a pre-thrombotic state.Methods The biochemical markers’ levels in plasma for platelet activity [soluble P-selectin (GMP-140)],states of thrombin generation [antithrombin Ⅲ (AT Ⅲ) and protein C (PC)],fibrinolysis [D-dimer (DD), plasminogen activator inhibitor 1 (PAI-1),tissue plasminogen activator (t-PA) and FDP] and von Willebrand factor (vWF) were determined from blood specimens obtained from the femoral veins and arteries and the right and left atria of 43 consecutive patients (20 with atrial fibrillation and 23 with sinus rhythm) with mitral stenosis (MS),undergoing percutaneous mitral valvuloplasty. The same parameters were compared with those of 15 control subjects,who had no detectable heart disease,but with paroxysmal supraventricular tachycardia undergoing radiofrequency catheter ablation of the left accessory pathway through a transseptal passage. Results Blood from the left atrium contained an excessive amount of platelet activity,thrombin generation and fibrinolysis compared with the blood from the right atrium,and the femoral veins and arteries. However blood from the right atrium was much lower in these activities when compared with those from the left atrium,and the femoral veins and arteries in both groups. Compared with those in the control subjects, GMP-140 in the left atrium was significantly higher ( P <0.05) and AT Ⅲ was significantly lower ( P <0.05) in patients with MS. Compared with the patients with MS and spontaneous left atrial echocontrast (LASEC)≤1,the patients with MS and LASEC≥2 had significantly higher levels of GMP-140 in plasma ( P <0.05),and significantly lower levels of AT Ⅲ ( P <0.05) and PC ( P <0.01) levels in the left atrium. However, there were no significant differences between patients with atrial fibrillation and those with sinus rhythm regarding amounts of plasma coagulation markers in the left atrium. Univariate regression analysis revealed that LASEC was negatively correlated with plasma levels of blood from the left atria in the patients with MS. Conclusion Coagulability is increased in the left atria of patients with MS and is positively correlated with LASEC.
