Objective: To study the effects of Total Saponins of Panax Pseudoginseng injection on unstable angina pectoris (UAP) . Methods :Forty-eight cases of UAP patients were randomly divided into Total Saponins of Panax Pseudoginseng injection treatment group and routine treatment group. The serum levels of plasminogen activator inhibitor (PAI), soluble intercellular adhesion molecule-1 (SICAM-1) and C-reactive protein (CRP) after two weeks treatment in two groups were observed. Results:The total effective rate was significantly higher in Total Saponins of Panax Pseudoginseng injection treatment group than in control group. The indexes of PAI after Total Saponins of Panax Pseudoginseng injection treatment were lower. The levels of SICAM-1 and CRP were lower in Total Saponins of Panax Pseudoginseng injection treatment group than those in control group. Conclusion:Total Saponins of Panax Pseudoginseng injection is an effective drug for UAP, and it obviously improves fibrinolytic activity and relieves inflammatory reaction.

The purpose of this study was to determine the role of lipid peroxidation by measuring the induced-chemiluminescence (ICL) of plasma and lung lymph in endotoxin-induced acute lung injury in awake sheep. The ICL of aortic plasma and lung lymph were significantly increased, but the ICL of venous plasma was not significantly increased after endotoxin infusion. The peak level of ICL was increased and its time was delayed after endotoxin. We conclude that lipid peroxidation plays an important role in endotoxin-induced acute lung injury, and ICL of arterial plasma is a sensitive marker in reflecting oxidant damage in lung.

ObjectiveTo analyze the stress contribution of different cement volume to the adjacent vertebral endplates in percutaneous kyphoplasty (PKP) so as to explore the possible mechanism of adjacent vertebral fractures after PKP.Methods The three-dimensional finite element model of osteoporotic thoracolumbar vertebral compression fractures was established to simulate vertebral body partial restoration (80％) with PKP.During the process,two doses of bone cement ( polymethylmethacrylate,PMMA) were filled in the vertebral body (4.0 ml bone cement filling 15％ of the vertebral body volume and 8.0 ml bone cement filling 30％ of the vertebral body volume).Endplate stress under conditions of axial compression,flexion and extension was analyzed. ResultsRegarding the two filling doses in PKP,the adjacent vertebral endplate stress under the above-mentioned conditions was all increased at T11 and L1 vertebral body compared with that before operation.Meanwhile,endplate stress had positive correlation with the cement volume and the stress concentrated largely in the anterior and middle parts of endplate.ConclusionsThe stress of adjacent vertebral endplate is positively correlated with cement volume,with anterior and middle parts of endplate as the stress concentration.The probability of adjacent vertebral fractures shows a rising trend with the increase of cement volume in PKP.

Objective To evaluate the significance of myocardial bridge and find a reasonable diagnosis and treatment strategy.Methods Sixty-three myocardial bridge patients and sixty-three patients with negative results of coronary artery angiography were reviewed.The clinical data of symptoms,electrocardiogram,exercise tests,coronary artery angiography,therapeutics and the serum levels of C-reactive protein(CRP)were analyzed.Results The symptoms of chest distress and chest pain were found in myocardial bridge patients.Myocardial consumption of oxygen augmentation causes the symptoms of aggravation.Positive results of electrocardiogram and exercise tests in many of myocardial bridge patients were examined.There were no relationship with severity of myocardial bridge artery stenosis.Most of myocardial bridge were discovered in anterior descending branch.At present,the main treatment of myocardial bridge was drug therapeutics.After treatment,the serum levels of CRP was significantly decreased.Conclusion Myocardial bridge was anatomy abnormality with important clinical significance.The serum levels of CRP can be used to evalue the therapeutic efficacy of myocardial bridge.

A simple and high throughput method was developed and validated for simultaneous determination of valproic acid and its two toxicant ene-metabolites, 2-enevalproic acid and 4-enevalproic acid in epilepsy patient plasma using liquid chromatography–tandem mass spectrometry. Probenecid was used as in-ternal standard and solid-phase extraction was selected for sample preparation. A chromatographic separation was performed on an Agilent Poroshell SB-C18 column (50 mm ? 4.6 mm i.d., 2.7μm) by an optimized gradient elution at a flow rate of 0.9 mL/min. The total run time was 7 min. Electrospray ionization was used in negative ion mode by multiple reaction monitoring of the precursor-to-product ion transitions at m/z 143.0-143.0 for valproic acid, m/z 140.9-140.9 for 2-enevalproic acid and 4-enevalproic acid for their poor fragments, and m/z 283.9-239.9 for probenecid. The results showed good linearity of valproic acid, 2-enevalproic acid and 4-enevalproic acid in their respective linear ranges. The correlation coefficients were more than 0.998. The intra- and inter-day precision of the assay was less than 11.0%and the accuracy ranged from 2%to 12%. This analytical method was successfully applied to assay plasma concentrations of valproic acid and its two ene-metabolites in epilepsy patient plasma and used for therapeutic drug monitoring.

Aim To investigate the preventive effect of Polygonum Multiflorum (PM)on the deteriorated mi-cro-structure and biomechanical properties induced by prednisone.Methods Ninety 6-month-old male Sprague-Dawley rats were randomly divided into nine groups,which were control,prednisone,CAL,30%ethanol eluent of the PM(H,M,L),PM(H,M,L). Prednisone was gavaged to rat for 21 weeks as model group of osteoporosis.Meanwhile,tested herbal ab-stract were orally administrated to the modeled rats in-duced by prednisone.At the end of the experiment, the right femur was collected for micro-CT scanning, three-dimensional reconstruction and biomechanical test.Results Compared with the control group,mod-el group showed destruction of bone microarchitecture, BV /TV fell 28.6%(P <0.05),bone biomechanical parameters decreases,and stiffness fell 29.7%(P <0.01 ). Compared with the model group, positive group had significantly improved effect on bone micro-architecture,and biomechanical parameters,BV /TV increased 46.7%(P <0.01 ),and stiffness increased 25.9%(P <0.01 ).30% ethanol eluent of the PM (M,L)dose may improve bone microstructure by in-creasing BV /TV 46.7% (P <0.01 ),40.0% (P <0.05)respectively,PM(H)may improve the biome-chanical parameters by increasing stiffness 24.7%(P<0.05),and 30% ethanol eluent of the PM(H)and PMhigh-dose may improve the biomechanical parame-ters,but not as positive group.Conclusions Predni-sone reduces biomechanical properties of rat femur and deteriorates femoral microstructure.30% ethanol eluent of the PM(M,L)and PM(H)plays a preventive role in the changes of micro-structural and biomechanical properties by prednisone,and increases BMD,whereas other groups have no significant preventive effect.

OBJECTIVETo explore the characteristics and therapies of patients with acute myocardial infarction (AMI) in Wuxi city, China.

METHODSA network was established to obtain information of patients with AMI who were admitted to 9 designated hospitals between 2011 and 2012. A total of 1 714 patients were enrolled (1 334 males, 754 smokers, 1 076 hypertension, 270 hyperlipidemia and 398 diabetes) including 1 410 patients with acute ST-segment elevation myocardial infarction (STEMI) and 304 patients with acute non ST-segment elevation myocardial infarction (NSTEMI). Patients' characteristics, therapies, the incidence of major adverse cardiovascular events (MACEs) and all-cause mortality were analyzed.

RESULTS(1) Medication therapy was as follows: antiplatelet therapy 98.3% (1 685 cases) , beta-blockers 59.1% (1 013 cases) , ACEI or ARB 67.6% (1 159 cases) , statins 98.1% (1 682 cases) , and nitrates 71.1% (1 218 cases) . Of the patients, 7.1% (132 cases) received temporary pacemakers, 34.0% (480 cases) with acute STEMI underwent reperfusion [direct PCI 18.4% (260 cases) and thrombolysis 15.6% (220 cases)]. (2) According to the hospital admission data, patients were divided into three groups: group A, transported to the hospital by ambulance (n = 361); group B, transported to the hospital by private vehicles (n = 1 318); and group C, AMI occurred in the hospital (n = 35). The median time of AMI onset to physician contact of the 3 groups was 178 min, 368 min, and 9 min, respectively. The median time from AMI onset to the first ECG was 181 min, 379 min, and 10 min, respectively. The median time from AMI onset to cardiology specialist consultation was 187 min, 431 min, and 69 min, respectively. AMI onset-to-physician contact, AMI onset-to-first ECG, and AMI onset-to-specialized treatment time was the shortest in group C, followed by group A and group B. For patients with STEMI underwent reperfusion therapy, the median AMI onset-to-reperfusion therapy time was significantly shorter in group A patients than group B patients [thrombolysis group: 224(171, 514) min vs. 378 (158, 785) min, PCI group: 318 (154, 674) min vs. 489 (143, 816) min, all P < 0.05]. (3) The total incidence of MACEs was 16.3% (279/1 714), the all-cause in-hospital mortality rate was 13.1% (224/1 714). According to the AMI onset-to-physician contact, patients were divided into 4 groups: <3 h, 3-6 h, 6-12 h, and >12 h. The incidence of MACEs [4.4% (23/517), 13.3% (60/451), 19.1% (77/404) and 34.8% (119/342),χ(2) = 114.36, P < 0.01] and all-cause in-hospital mortality rate [4.1% (21/517) , 10.4% (47/451), 18.6% (75/404), 23.7% (81/342), χ(2) = 84.36, P < 0.01] increased in proportion to the time of AMI onset-to-physician contact. Among STEMI patients, the incidence of MACEs [5.8% (15/260) , 12.3% (27/220) , 20.9% (194/930) ,χ(2) = 39.93, P < 0.01] and all-cause in-hospital mortality [1.5% (4/260) , 10.0% (22/220) , 18.2% (170/930) ,χ(2) = 50.90, P < 0.01] was the lowest in the primary PCI group, followed by thrombolysis group and was the highest in the early conservative treatment group.

CONCLUSIONSGuideline is well followed in terms of drug treatments of AMI in this cohort, but only a small proportion of AMI patients in Wuxi received reperfusion therapy. There is a considerable out-of-hospital time delay for AMI patients in this cohort which is shorter in group A than in group B. All-cause in-hospital mortality and MACEs is the lowest in AMI patients underwent primary PCI.
