PURPOSE: To compare the effects of empirical and modified hemostatic resuscitation for liver blast injury combined with seawater immersion. METHODS: Thirty rabbits were subjected to liver blast injury combined with seawater immersion, and were then divided into 3 groups randomly (n = 10 each): group A (no treatment after immersion), group B (empirical resuscitation with 20 mL hydroxyethyl starch, 50 mg tranexamic acid, 25 IU prothrombin complex concentrate and 50 mg/kg body weight fibrinogen concentrate), and group C (modified resuscitation with additional 10 IU prothrombin complex concentrate and 20 mg/kg body weight fibrinogen concentrate based on group B). Blood samples were gathered at specified moments for assessment of thromboelastography, routine coagulation test, and biochemistry. Mean arterial pressure, heart rate, and survival rate were also documented at each time point. The Kolmogorov-Smirnov test was used to examine the normality of data distribution. Multigroup comparisons were conducted with one-way ANOVA. RESULTS: Liver blast injury combined with seawater immersion resulted in severe coagulo-fibrinolytic derangement as indicated by prolonged prothrombin time (s) (11.53 ± 0.98 vs. 7.61 ± 0.28, p＜0.001), activated partial thromboplastin time (APTT) (s) (33.48 ± 6.66 vs. 18.23 ± 0.89, p＜0.001), reaction time (R) (min) (5.85 ± 0.96 vs. 2.47 ± 0.53, p＜0.001), decreased maximum amplitude (MA) (mm) (53.20 ± 5.99 vs. 74.92 ± 5.76, p＜0.001) and fibrinogen concentration (g/L) (1.19 ± 0.29 vs. 1.89 ± 0.32, p = 0.003), and increased D-dimer concentration (mg/L) (0.38 ± 0.32 vs. 0.05 ± 0.03, p = 0.005). Both empirical and modified hemostatic resuscitation could improve the coagulo-fibrinolytic states and organ function, as indicated by shortened APTT and R values, decreased D-dimer concentration, increased fibrinogen concentration and MA values, lower concentration of blood urea nitrogen and creatine kinase-MB in group B and group C rabbits in comparison to that observed in group A. Further analysis found that the R values (min) (4.67 ± 0.84 vs. 3.66 ± 0.98, p = 0.038), APTT (s) (23.16 ± 2.75 vs. 18.94 ± 1.05, p = 0.001), MA (mm) (60.10 ± 4.74 vs. 70.21 ± 3.01, p < 0.001), and fibrinogen concentration (g/L) (1.68 ± 0.21 vs. 1.94 ± 0.16, p = 0.013) were remarkably improved in group C than in group B at 2 h and 4 h after injury. In addition, the concentration of blood urea nitrogen (mmol/L) (24.11 ± 1.96 vs. 21.00 ± 3.78, p = 0.047) and creatine kinase-MB (U/L) (85.50 ± 13.60 vs. 69.74 ± 8.56, p = 0.013) were lower in group C than in group B at 6 h after injury. The survival rates in group B and group C were significantly higher than those in group A at 4 h and 6 h after injury (p < 0.001), however, there were no statistical differences in survival rates between group B and group C at each time point. CONCLUSIONS Modified hemostatic resuscitation could improve the coagulation parameters and organ function better than empirical hemostatic resuscitation.

OBJECTIVETo systematically evaluate the clinical effectiveness and safety of Danshen Injection (, DS) as one adjuvant treatment for conventional therapy with Western medicine (WM) for unstable angina pectoris (UAP).

METHODSUsing literature databases, a thorough and systematic retrieval of randomized controlled trials (RCTs) comparing DS plus WM with WM was conducted from inception to April 2015. The extracted data from included studies was analyzed by Review Manager 5.2 software. The Cochrane risk of bias tool was used to assess the quality of included studies, and Begg's and Egger's tests conducted by Stata 12.0 were used to evaluate the potential presence of publication bias.

RESULTSA total of 17 RCTs, which involving 1,433 participants, were identified and reviewed. The meta-analysis indicated that the combined use of DS and WM was significantly superior to WM alone for UAP in terms of the total effectiveness rate of angina pectoris [risk ratio (RR) =1.23, 95% confidence interval (CI): 1.17, 1.29, P<0.01] and the total effectiveness rate of electrocardiogram (ECG) [RR=1.18, 95%CI: 1.06, 1.30, P=0.001]. Additionally, DS could also further reduce the content of fibrinogen, adjust blood lipid level, correct T wave inversion, and so on. Fifteen adverse drug reactions were reported in two studies, Four of which appeared in the experimental group.

CONCLUSIONBased on the systematic review, the combined use of DS and WM was more effective than WM alone, it can be further widely used in clinic, however, there was no exact conclusion for its safety.

BACKGROUND: Postoperative pain relief can be achieved with various modalities. However, there are only few reports that have analyzed postoperative analgesic techniques in total hip arthroplasty patients. The aim of this retrospective study was to compare the postoperative outcomes of three different analgesic techniques after total hip arthroplasty. METHODS: We retrospectively reviewed the influence of three analgesic techniques on postoperative rehabilitation after total hip arthroplasty in 90 patients divided into three groups (n = 30 patients per group). Postoperative analgesia consisted of continuous epidural analgesia (Epi group), patient-controlled analgesia with morphine (PCA group), or a continuous femoral nerve block (CFNB group). We measured the following parameters relating to postoperative outcome: visual analog scale scores, the use of supplemental analgesia, side effects, length of the hospital stay, plasma D-dimer levels, and the Harris hip score. RESULTS: Each group had low pain scores with no significant differences between the groups. The PCA group had a lower frequency of supplemental analgesia use compared to the Epi and CFNB groups. Side effects (nausea/vomiting, inappetence) and day 7 D-dimer levels were significantly lower in the CFNB group (p < 0.05). There were no significant differences between the groups in terms of the length of the hospital stay or the Harris hip score. CONCLUSIONS: Although there were no clinically significant differences in outcomes between the three groups, the CFNB provided good pain relief which was equal to that of the other analgesics with fewer side effects and lower D-dimer levels in hospitalized patients following total hip arthroplasty.

OBJECTIVEA first report of 3 patients who developed hypofibrinogenemia due to long-term administration of hemocoagulase.

METHODSThe clinical data of three patients with hypofibrinogenemia due to long-term administration of hemocoagulase were analyzed, and the related literature was reviewed.

RESULTSCase 1, a two-year old girl, had liver traumatic rupture and then treated with massive transfusion and fibrinogen infusion in addition to intravenous recombinant factor VIIa (two times) and hemocoagulase (2 U/d). The liver wound bleeding was soon stopped. However, her plasma fibrinogen level decreased to 0.12 g/L after continuous administration of hemocoagulase for 18 days. Case 2, a three-year old boy, had liver traumatic rupture and was treated with surgical repair, and then received hemocoagulase (2 U/d). On the 8th day, a large amount of blood was found to exude from abdominal cavity drainage tube and indwelling venous catheter, and his fibrinogen dropped to 0.24 g/L. Case 3 was a 45 year-old man who underwent a total mandibular resection because of malignant tumor, and he was given hemocoagulase (4 U/d). A continuous blood oozing was noted from his operation incision, and his fibrinogen level decreased to 0.25 g/L. All the three patients'plasma fibrinogen levels and coagulation tests returned to normal ranges after discontinuation of hemocoagulase administration and supplement of fibrinogen, and the bleeding stopped in cases 2 and 3.

CONCLUSIONLong-term use of hemocoagulase could induce hypofibrinogenemia and severe bleeding.

BACKGROUNDElevated fibrinogen (Fg) level is a known risk factor for ischemic stroke. There are few clinical trials on oral fibrinogen-depleting therapies for secondary ischemic stroke prevention. We aimed to assess the effects of one-year therapy with oral lumbrokinase enteric-coated capsules on secondary ischemic stroke prevention.

METHODSThis is a multicenter, randomized, parallel group and controlled study that began treatment in hospitalized patients with ischemic stroke and continued for 12 months. Patients were randomized to either the control group that received the standard stroke treatment or the fibrinogen-depleting group that received the standard stroke treatment plus enteric-coated lumbrokinase capsules. The NIH Stroke Scale scores (NIHSSs) and plasma Fg level were recorded. The carotid artery intima-media thickness (IMT) and status of plaques were examined through carotid ultrasound examination. Primary outcomes included all-cause mortality, any event of recurrent ischemic stroke/transient ischemic attack (TIA), hemorrhagic stroke, myocardial infarction and angina, and other noncerebral ischemia or hemorrhage. Kaplan-Meier survival analysis and the Long-rank test were used to compare total vascular end point incidence between the two groups. Comparison of median values between two groups was done by the Student t test, one-way analysis of variance (ANOVA), or non-parametric rank sum test.

RESULTSA total of 310 patients were enrolled, 192 patients in the treatment group and 118 patients in the control group. Compared to the control group, the treatment group showed favorable outcomes in the Fg level, carotid IMT, the detection rate of vulnerable plaques, the volume of carotid plaques, NIHSS scores, and incidence of total vascular (6.78% and 2.08%, respectively) and cerebral vascular events (5.93% and 1.04%, respectively) (P < 0.05). In the treatment group, the volume of carotid plaques was significantly related to the carotid IMT, the plaque diameter, width and number (P = 0.000, 0.000, 0.000, 0.022; F = 13.51, 2.52, 11.33, -3.29, but there was a weak correlation with the Fg level (P = 0.056). After 1-year therapy, the incidence of overall vascular end points was reduced by 4.7%.

CONCLUSIONLong-term oral fibrinogen-depleting therapy may be beneficial for secondary ischemic stroke prevention.

Healthy Beagle dogs were administrated with batroxobin by intravenous infusion at high, medium and low doses. The study of pharmacodynamics and pharmacokinetics was intended to clarify the relevance of them and provided strong evidence for clinical use of batroxobin. The blood samples were collected after injection based on the time schedule and samples were tested by ELISA method to get the concentration of batroxobin. At the same time, changes of prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and D-dimmer were tested. The results showed that the concentration of D-D increased significantly after administration compared with that of before administration. The main pharmacokinetic parameters were as follows: t1/2 were (2.27 +/- 0.42) h, (10.65 +/- 2.19) h and (11.01 +/- 3.51) h; C(max) were (11.9 +/- 1.72) ng x mL(-1), (154.53 +/- 12.38) ng x mL(-1) and (172.14 +/- 47.33) ng x mL(-1); AUC(last) were (29.38 +/- 3.69) ng xh x mL(-1), (148.43 +/- 72.85) ng x h x mL(-1) and (599.22 +/- 359.61) ng x h x mL(-1). The elimination of batroxobin was found to be in accord with linear kinetics characteristics. The results of pharmacodynamics showed that D-dimmer level increased significantly after the administration of batroxobin, which was similar with the changes of batroxobin plasma concentration. Simultaneously, Fib concentrations in Beagle dog blood decreased significantly after the iv administration of batroxobin, while recovered to base level after 48 hours. PT, TT and APTT significantly became longer after administration, which returned to normal level after 48 hours. Especially, the D-dimmer levels and the batroxobin concentration in plasma after intravenous infusion of the drug were synchronized in Beagle dogs. Changes between PD/PK results had obvious correlation, and the D-dimmer levels in plasma can be one of the important monitoring indicators of batroxobin in thrombolytic medication.

In order to discover the mechanism of Xuebijing oral effervescent tablet (XBJOET) to treat infectious diseases, the effect of XBJOET on endotoxin induced rabbit fever and disseminated intravascular coagulation (DIC) was investigated. Auricle microcirculation in rabbit was detected by laser speckle blood perfusion imager system; coagulation function was measured by coagulation analyzer, fibrinolytic system was quantified by Elisa assay and micro thrombosis in tissues was observed with HE staining under light microscope. The results demonstrated that the body temperature of rabbit decreased significantly at 1-3 h after administration with 4.8, 2.4 and 1.2 g x kg(-1) XBJOET to endotoxin induced DIC rabbit model, the auricle microcirculation blood flow in model group (54.45 +/- 14.53) PU was lower than that in control group (77.18 +/- 12.32) PU. The auricle microcirculation blood flow increased markedly and there was significant difference between model group and 1.2 g x kg(-1) XBJOET group. There was significant difference between model group and control group in the content of PAI1 and FIB. The PAI1 levels in model and control groups were (30.48 +/- 2.46) ng x mL(-1) and (20.93 +/- 3.25) ng x mL(-1), respectively. The FIB levels in model and control group were (3.34 +/- 1.09) g x L(-1) and (4.84 +/- 1.10) g x L(-1), respectively. The content of PAI1 in rabbit plasma decreased notably, there were significant differences between model group and 4.8, 2.4 g x kg(-1) XBJOET groups. On the contrary the content of FIB increased. XBJOET possessed pharmacological activities of curing infectious fever and DIC, the mechanism of which is related to amelioration of microcirculation disturbance, inhibition of fibrinolytic system activation and coagulation and micro thrombosis elimination.

OBJECTIVE: To investigate the effect of anti-Helicobacter pylori on the inflammation mediators and prognosis in patients with acute cerebral infarction. METHODS: Routine urease test was carried out in patients with acute cerebral infarction in our hospital. The acute cerebral infarction patients with positive urease test were randomly divided into a treatment group (conventional therapy+anti-Helicobacter pylori therapy) and a control group (conventional therapy). C-reactive protein, triglycerides, and fibrinogen changes were examined before and after the treatment, symptoms of acute cerebral infarction conditions were observed,and 6-months and 1- year cerebral infarction readmission rates were measured in the 2 groups. RESULTS: Compared with before the treatment,the C-reactive protein, triglycerides, and plasma fibrinogen decreased significantly in the treatment group, while there was no significant change in the control group. The 6-months and 1-year cerebral infarction readmission rates were significantly lower than those in the control group. CONCLUSION H. pylori infection may be a risk factor for cerebral infarction. A positive anti-Helicobacter pylori infection treatment can significantly improve the efficiency of cerebral infarction and reduce the short-term readmission rate.

OBJECTIVETo establish a pig model of fulminant hepatic failure for evaluating the pre-clinical efficacy of drug treatment on severe hepatitis, and to detect the expression of fibrinogen-like protein-2 (fgl2) prothrombinase in the model, so as to provide basis for gene therapy targeting to fgl2 for fulminant hepatic failure.

METHODD-galactosamine hydrochloride was used to induce pig model of fulminant hepatic failure, and the experiment animals were divided into model group (rapid injection of D-galactosamine hydrochloride by ear vein, a dose of 1.2 g/kg) and negative control group (5% Glucose). Clinical, biochemical and pathological changes of animals were observed. The expression of pigs fgl2 (pfgl2) mRNA in liver tissue was detected by real time RT-PCR, the expression of pfgl2 protein in liver tissue was detected by immunohistochemistry.

RESULTSA pig model of fulminant hepatic failure was successfully established using the D-galactose hydrochloride; Real time RT-PCR of liver fgl2 mRNA showed that fgl2 mRNA expression was increased significantly in liver tissue of fulminant hepatic failure pig model compared with the control group (P = 0.016); Immunohistochemical staining showed that there were fgl2 protein expression in liver tissue of fulminant hepatic failure pig model, mainly in the membrane and cytoplasm of hepatocytes, inflammatory cells, liver sinusoidal endothelial cells and vascular endothelial cells of liver cell necrosis region. However, there are no fgl2 positive staining on negative control.

CONCLUSIONSThe pig model of fulminant hepatic failure induced by D-galactosamine hydrochloride is similar to human pathological process and can be used to evaluate the pre-clinical efficacy and safety of drug treatment on fulminant hepatic failure. Abnormal expression of pfgl2 at both mRNA level and protein level in the liver of fulminant hepatic failure pig model shows that pfgl2 induced coagulation pathway is also involved in the development of fulminant hepatic failure. Gene therapy targeting fgl2 genes for fulminant hepatic failure may provide a new means for the treatment of fulminant hepatic failure.
