ABSTRACT
【Objective】 To evaluate the effect of adding platelet GPⅡb/Ⅲa receptor inhibitor (A adjuvant) into the Batroxobin cup (A cup) on the accuracy of the thromboelastogram (TEG) platelet aggregation function test using the functional fibrinogen (function fiber cup) test results as a standard. 【Methods】 From December 2019 to May 2020, 100 (persons) whole blood samples were collected from patients who visited the Department of Neurology, Department of Cardiology, Department of General Affairs and Department of Rehabilitation of our hospital for TEG platelet aggregation function test, and the blood standard samples were divided into MA <25 mm group (n=50) and MA≥25 mm group (n=50) according to the A-cup blood clot intensity (MA) value (mm) measured by TEG, the two groups were subdivided into A cup group (n=50, respectively), A auxiliary group (adding A auxiliary in A cup) (n=50, respectively), and functional fiber cup group (n=50, respectively), each subgroup was tested once again. The linear correlation, platelet inhibition and the consistency of drug efficacy interpretation results in platelet Adenosine diphosphate (ADP) and Arachidonic acid (AA) pathway respectively between the three subgroups were compared. 【Results】 (1) In the MA<25mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (32.00±17.44) % vs (30.19±17.44) % vs (30.07±16.18) %, (24.3±33.53) % vs (22.53±30.9) % vs (22.37±31.2) %, respectively (R2 were all>0.975); (2) In the MA≥25 mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (34.34±33.59) % vs (18.45±24.42) % vs (18.01±24.33) %, (23.19±39.33) % vs (8.48±21.75) % vs (8.31±21.7) % ( R2 between the A cup group and the A adjuvant group were all<0.8, and R2 between the A adjuvant group and the functional fibrinogen cup group were all >0.975); (3)Take the test result of the functional fibrinogen cup as the standard, the correct rates of ADP and AA pathway drug efficacy interpretation were 82% (41/50) vs 100% (50/50) and 84% (42/50) vs 100% (50/50) respectively (P<0.05) between the A-cup group and the A adjuvant group, while the interpretation results of drug efficacy of the two pathway were consistent between the A adjuvant group and the functional fibrin cup group (P>0.05). 【Conclusion】 Adding A adjuvant to TEG platelet aggregation function test can effectively inhibit non-specifically activated platelets in the A cup in the detection of platelet aggregation function, truly reflect the function of fibrinogen and improve the accuracy of platelet inhibition rate.
ABSTRACT
OBJECTIVE:To observe therapeutic efficacy and safety of batroxobin in the treatment of senile sudden deafness. METHODS:Totally 102 senile patients with sudden deafness were randomly divided into control group(51 cases)and observation group (51 cases). Control group was given routine treatment as Ginkgo biloba extract injection 105 mg+Dexamethasone sodium phosphate injection 30 mg+Methotrexate tablets 6 mg orally. Based on control group,observation group was additionally given Ba-troxobin injection 10 BU added into 0.9% Sodium chloride injection 100 mL intravenously,running out within 1 h,every 2 days, and then given 5 BU added into 0.9% Sodium chloride injection 100 mL intravenously,running out within 1 h. Both groups were treated for 10 d. Clinical efficacy,hearing recovery time,ear drowsiness disappearance time,dizziness disappearance time and tin-nitus disappearance time of 2 groups were observed. The levels of pure tone threshold,plasma specific viscosity(ns),high shear rate of whole blood viscosity(nbh),low shear rate of whole blood viscosity(nbl),hematocrit(HCT),erythrocyte sedimentation rate (ESR),Fb,endothelin (ET) and nitric oxide (NO) were observed before and after treatment as well as the occurrence of ADR. RESULTS:The total response rate of observation group was significantly higher than that of control group;hearing recovery time,ear drowsiness disappearance time,dizziness disappearance time and tinnitus disappearance time were significantly shorter than control group,with statistical significance(P0.05). After treatment,the levels of pure tone threshold,ns,nbh,nbl,HCT,ESR,Fb and ET in 2 groups were significantly lower than before;the observation group was significantly lower than the control group. The levels of NO in 2 groups were significantly higher than before;the obser-vation group was significantly higher than the control group,with statistical significance(P<0.01). During treatment,no obvious ADR was found in 2 groups. CONCLUSIONS:Based on routine treatment,batroxobin is effective in the treatment of sudden deaf-ness in the elderly,can effectively relieve the symptoms,improve the recovery of local blood flow and inner ear microcirculation disturbance with good safety.

ABSTRACT
Objective To assess the clinical value of batroxobin plus aspirin therapy in reducing the incidence of arterial re-stenosis or re-occlusion in diabetic patients with lower-limb ischemia after receiving angioplasty. Methods A total of 110 diabetic patients with symptomatic arterial obstructions were randomly divided into study group (n=50) and control group (n=60). Aspirin 100 mg/d plus batroxobin 5 IU every other day for six times was used in patients of the study group, while only aspirin 100 mg/d was used in patients of the control group. The follow-up finishing point was the end of 12 months. The arterial re-stenosis or re-occlusion was evaluated with magnetic resonance angiography (MRA) and/or vascular sonography. Amputation above the ankle, death, and the cumulative rate of amputation or death were determined, and the limb salvage and survival rates were assessed by using Kaplan-Meier analysis method. Results Twelve months after the treatment, the occurrence of restenosis in the study group and the control groups was 42.8%and 28.9% respectively (P = 0.002). MR angiography and color- duplex sonography revealed that the restenosis occurrence was much higher in infrapopliteal artery (P = 0.003) and in longer (length > 10 cm) diseased artery (P = 0.001). Twelve months after angioplasty Kaplan-Meier analysis showed that the limb salvage-survival rates of the study group and the control group were 78.2%and 93.5%respectively (log-rank test, P = 0.032 4). Conclusion Combination use of batroxobin and aspirin can effectively reduce the occurrence of restenosis after arterial angioplasty, and the clinical effect is particularly better for the artery distal to the knee and the artery with longer lesion (length > 10 cm), besides this treatment can also improve limb salvage rate.

ABSTRACT
Objective To evaluate the efficacy and safety of Baquting (hemocoagulase for injection)for hemostasis in biliary surgery. Methods A total of 240 patients were divided into hemocoagulase group (n=120)and control group (n=120).Normal saline was used instead of hemocoagulase in the control group.The two groups were compared in terms of intraoperative blood loss,blood loss per unit area, total drainage volume at 3 d after operation,and transfusion volume of suspended red blood cells (RBCs)in the perioperative period,and the effect of hemocoagulase on coagulation function was evaluated.Comparison of measurement data was made by t test.Results Compared with the control group,the hemocoagulase group had significantly less intraoperative blood loss (94.3 ±11.4 vs 128.6 ±10.3 ml,t =24.456,P0.05).Conclusion Hemocoagulase is effective and safe in preventing and treating bleeding during and after biliary surgery and can reduce intraoperative and postoperative blood loss and requirement for suspended RBC transfusion in the perioperative period.
ABSTRACT
Objective To investigate the interactive effects between batroxobin and low molecular weight heparin(LMWH)in reducing peri-operative blood loss and coagulation function in patients who undergone the total hip replacement surgery. Methods 240 ASA Ⅰ-Ⅲ patients received 4 000 IU LMWH 12 hours preoperatively before undergoing the total hip replacement operation,were randomly divided into two groups:testing group (Group A,n=120) and control group(Group B,n=120)receiving 2 U batroxobin or 50 mg mannitol 10 minutes before incision respectively. Perioperative blood loss,postoperative 24 hours drainage and blood routine test, prothrombin time (PT),activated partial thromboplastin time(APTT) and fibrinogen(FIB) were measured respectively. Deep vein thrombosis (DVT) were measured through color Doppler B-ultrasound 3 days after the operation. Results The perioperative blood loss in Group A (422.64 ml)was less than that in Group B(667.67 ml)(P<0.01)while red blood cell,hemoglobin, red blood cell volume and platelet were decreasing after operation in both groups but no significant difference was found between the two groups(P>0.05). There were no drug-related adverse effects found in the two groups,neither the difference in hospitalization between the two groups(P>0.05). Conclusion Batroxobin (2 U) could reduce the perioperative blood loss in patients with LMWH who had undergone the total hip replacement operation but did not show adverse effect on DVT.
