Objective The study evaluated the efficiency and safety of a short-acting full-dose fibfinolytic regimen to promote early infarct-related artery (IRA) patency during the inherent delay experienced by infarction patients referred for angioplasty as the principal recanalization modality. Method Accepted aspirin and heparin, 75 patients were treated by an intravenous bolus of 20 mg recombined tissue-type plasminogen activator (rt-PA), then followed by 80 mg over 30 minutes. Patients were to undergo angiography as soon as possible following study drug. If the IRA was occlude (TIMI flow grade 0 or 1),or was open but with ≥50% stenosis, immediate early PTCA at the same time. The end point included patency rates on catheterzation laboratory (cath Lab) arrival, technical results when PTCA was performed, complication rates, clinical adverse events rates and left ventricular (LV) function by treatment assignment in two weeks. Results Patency on Cath lab arrival was 88% with combination treatment group (26% Thrombolysis in myocardia infarction trial TIMI-2, 66%TIMI-3), and 36%with primary PTCA group (20%TIMI-2, 16%TIMI-3), (P

Objective To observe the change of serum TG in elderly diabetic patients after fatty meal.Methods The diabetic patients and non-diabetic patients of fasting normotriglyceridemia ate the fatty test meal after having been fasting for 12h.Serum lipid were measured at 0,2,4 and 6h after the meal.Results The serum TG level increased in the two groups after the meal,the diabetic patients had a higher TG-AUC than the non-diabetic patients (P

Objective To determine the effects of EGCG on lipopolysaccharide ( LPS)-induced neuroinflamma-tion and investigate the role of neuroprotection mediated by EGCG .Methods Primary cultures of rat gliacyte were used as an in vitro model to examine the effects of EGCG on LPS-induced neuronal damage .The intracellu-lar Glu andγ-GABA were quantified via HPLC .Then the protein level of TNF-α,IL-1βand IL-8 was determined by ELISA and Western blot assay .Results Compared with the control group , LPS apparently induced the pro-duction of intracellular ROS ( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures super-natant (P<0.05).Compared with the LPS group,EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein ( P<0.05 ) .LPS apparently induced the production of intra-cellular ROS( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures supernatant ( P <0.05 ) .EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein(P<0.05), and rugulated the concentration of Glu/γ-GABA(P<0.05).Conclusions EGCG is effective in protecting hosts against LPS-induced neuroinflammation through anti-inflammatory effects and regulating extracel-lular Amino acid levels .

Objective To observe the impact of lysophosphatidyl choline(LPC) on the expression of scavenger receptor class B type Ⅰ(SRBI) in L-20 cells and the impact of simvastatin.Methods Cultured hepatocytes were randomly assigned to normal group,LPC-damaged group and simvastatin group.The changes of mRNA and protein expression of SRBI in hepatic tissue were assayed by RT-PCR,immunocytochemistry and Western blot,respectively.Results The expression of SRBI was higher in LPC-damaged hepatocytes than that in normal cells at both mRNA and protein level(P

Objective To explore the effects of simvastatin on the protein expressions of urokinase-typeplasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1). Methods Male Sprague–Dawley rats were divided into saline group , LPS group and LPS plus simvastatin group , and were then pretreated with simvastatin (1 mg/kg) for 30 minutes before addition of LPS (8 mg/kg). Changes in left ventricular pressure were recorded. Ninety minutes after LPS injection, whole blood was collected from the inferior vena cava, and neutrophils were separated. The neutrophils were then lysed to detect levels of uPA and PAI-1. Results Left ventricular systolic pressure (LVSP: mmHg), maximal differential of left ventricular pressure (+dp/dtmax:mmHg/s), and heart rate (beats/min) were markedly decreased at different time points after administration of LPS, and maximal differential of left ventricular pressure increased in the rats receiving LPS as compared with those receiving saline, although the differences between the control and LPS groups were not statistically significant. LPS caused a great decline in uPA content and an elevation in PAI-1 content in neutrophils, but simvastatin diminished the impact of LPS on neutrophils. Conclusion Simvastatin plays a role in protection of cardiac function in rats with LPS-induced septic shock , and controls expressions of uPA and PAI-1 in neutrophils.

Objective To investigate the diagnosis and treatment of pulmonary tuberculosis in renal transplantation recipients.Method The clinical data of 8 renal transplantation recipients suffering from pulmonary tuberculosis infection were retrospectively analyzed.Result Fever,cough and expectoration were the most common symptoms,however,lacking typicality.Images of chest Xray and CT scan were various and couldn't verify TB infection from pneumonia.Seven of 8 cases were diagnosed through invasive methods,either bronchofibroscope or fiberthoracoscopy.Immunosuppressants were decreased in all cases.Three-drug regimens,including isoniazide,rifampicin and ethambutol or pyrazinarnide,were administrated as anti-tuberculosis chemotherapy.All the cases were cured,without episodes like acute rejection and liver function impairment.Conclusion Routine examinations are not sufficient to diagnose pulmonary tuberculosis in kidney transplantation recipients.While,invasive methods like bronchofibroscope and fiberthoracoscope are helpful.When diagnosed,patients should receive normative anti-tuberculosis treatment and immunosuppressive agents adjustment,which can benefit the prognosis of pulmonary tuberculosis in renal transplantation recipients.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

120 strains of endophytic bacteria identified by ERIC-PCR were isolated from wild and cultivated Glycyrrhiza uralensis plants which collected from Erdos Innermongolia province.The identified results indicated that Glycyrrhiza uralensis plants has plenty of endophytic bacterium in density and population,and the density is higher in root and leave than in stem.Partial sequence analysis of 16S rDNA gene of 82 strains indicated that these strains were in a high similarity with 19 known genus which belong to?、?、 ?-Proteobacteria、Firmicutes and Actinobacteria.The dominant genus were Bacillus sp.,Pseudomonas sp., Pantoea sp.and Serratia sp..

Objective To investigate the effect of different delivery modes and related obstetric factors on the short-term function of the pelvic floor.Methods One hundred and twenty healthy primiparae women were interviewed at 6-8 weeks postpartum,with 72 women in the vaginal delivery group and 48 women in the elective cesarean section group.Questionnaire on stress urinary incontinence and measurement of diastolic and contractive function of the pelvic floor muscles by electromyogram(EMG)were used for the evaluation and comparison.Results The prevalence of stress urinary incontinence in the vaginal delivery group and the elective cesarean section group was 21% and 10%(P=0.134),respectively.The values of the right act,right work,and average work surveyed by EMG in vaginal delivery group were significantly lower than those in cesarean section group(right act,12.9?0.8 vs 17.3?1.7,P
