Objective To investigate the changes in platele aciveation in terms of platelet fibrinogen receptor expression(PAC-1),P-selectin(CD62P),Thromboxane B2(TXB2),Endothlin(ET-1),Fibrinogen(FIB)in patients undergoing elective Sirolimus-eluting stents implantation and dual anti-platelet therapy.Methods Forty in-hospital patients with stable coronary heart disease(CHD)were enrolled in this study.Dural anti-platelet therapy with aspirin and clopidogrel were prescribed at least three days before operation to achieve sufficient inhibition of platelet activation in all patients.Peripheral artery blood samples were collected before the procedures,immediately and at 6 hours and 24 hours after the procedure,levels of PAC-1,CD62P,TXB2,ET-1 and FIB were measured.All patients were followed up for 6-12 months.Results Expression of PAC-1 and CD62P was increased significantly after stenting compared with pre-stenting and the peak appeared at 6 hours post-operation(PAC-1,P=0.001,CD62P,P=0.007,PAC1+CD62P,P=0.003).TXB2 was also increased and the peak appeared at 24 hours post operation(P=0.021).Plasma levels of ET-1 and FIB showed no difference before and after stenting.After CAG,expression of PAC-1 and CD62P,levels of TXB2,ET-1 and FIB had no significant differences compared with pre-CAG.No MACE happened in all patients.Conclusion The routine dual anti-platelet therapy cannot suppress platelet activation after elective coronary Sirolimus-eluting stents implantation.Plasma FIB and ET-1 levels were not affected by stents implantation.

We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

High resolution melting (HRM), based on melting curve analysis, requires not only saturating dyes that fluoresce in the presence of double-stranded DNA, but also higher resolution detection equipment. The melting curve is a novel method for sequence matching, genotyping and mutation scanning. The technology is simple, accurate, rapid, closed-tube, low-cost, and high-throughput, which make it gain more and more applications. This review article presents the basic principles, key factors and both the advantage and limitations of HRM. The potential application is discussed in the study of molecular identity of traditional Chinese medicine.

Objective To approach the curative effect of curing chronic obstructive pulmonary disease and Ⅱ type respiratory failure by noninvasive mechanical ventilation. Methods To retrospective analyze the clinical data of 60 cases chronic obstructive pulmonary disease and Ⅱ type respiratory failure,which was to be divided into detection group and control group by treatment way. Results The cough, expectoration,chest distress,rales of improving were better than control group, the respiratory frequency, heart rate, systolic arterial pressure were better than control group,the blood gas analysis result PaO2, PaCO2 of detection group were better than control group (P < 0. 05). The difference was statistical significance. Conclusion The curative effect of curing chronic obstructive pulmonary disease and Ⅱ type respiratory failure by noninvasive mechanical ventilation. It is worthy to be used in clinics.

ObjectiveTo compare the therapeutic effect, adverse effects and safety of leflunomide (LEF)and cyclophosphamide(CTX) on lupus nephritis(LN). Methods43 patients with reactive LN were randomly divided into two groups. Based on hormone application,22 cases in LEF group were given LEF orally and 21 cases in CTX group were given CTX intravenous drip discontinuously. They were followed up for six months. The related indexes and possible concomitant adverse effects were detected. ResultsThe total effective rate in LEF group was 81.8% and that in CTX group was 85.7%. The tolerance in LEF group was better and 3 cases had adverse effects. 13 cases in CTX group had adverse effects. ConclusionLEF had the same efficacy as CTX in the LN therapy, but the tolerance is better and the side effects are minor than CTX.

Objective To explore the value of tubercular antibody (TBAb) in the diagnosis of tuberculous pericarditis (TBP).Methods The TBAb in 38 patients were determined by colloidal gold (CG) and compared with 64 healthy control. Results The positive ratio in TBP group was significantly higher as compared with control group. The hydropericardium was significantly decreased or disappeared after 6 months of antituberculotic treatment by color Doppler ultrasonography. It seemed that patients were rehabilitated and electrocardiogram (ECG) was normal. Conclusion TBAb is valuable in the diagnosis,differential diagnosis or treatment of TBP.

Aim To investigate the role of calcitonin gene related peptide(CGRP),ATP sensitive potassium channel(KATP)and spinal nerve in the protective effect of intrathecal morphine preconditioning against myocardial postischemia injury in rats.Methods Rats were established intrathecal catheter placement and myocardial ischemia reperfusion models were randomly assigned to 10 groups:control group(CON);intravenous dimethylsulfoxide group(DMSO);intravenous CGRP8-37 group(CGRP8-37,a selective CGRP receptor antagonist,3 nmol?kg~-1);intravenous glibenclamide group(GLI,a non-selective KATP channel inhibitor,0.3 mg?kg~-1);intrathecal 10 ?l of 1% lidocaine group(LID);intrathecal 3?1 ?g?kg~-1 morphine preconditioning group(MPC);intravenous 3 nmol?kg~-1 CGRP8-37+MPC group(CGRP8-37+MPC);intravenous 0.3 mg?kg~-1 GLI+MPC group(GLI+MPC);intravenous 0.3 mg?kg~-1 GLI+LID group(GLI+LID).Indicators to be observed were MAP,HR and RPP(MAP?HR),the volume of area at risk(AAR)and infarct size(IS),and the area of myocardial infarction,which was demonstrated by IS/AAR.Results Compared to CON group,the volume of IS and IS/AAR was reduced in MPC,LID,LID+MPC and GLI+LID group(P

The relationship between the hepatic ischemia/reperfusion (I/R) injury and the balance of nitric oxide/endothelins (NO/ET) was studied. The changes of the ratio of NO/ET and the hepatic injury were observed in a rat hepatic I/R model pretreated with several tool drugs. In the acute phase of hepatic I/R injury, the ratio of plasma NO/ET was reduced from 1.58 +/- 0.20 to 0.29 +/- 0.05 (P < 0.01) and the hepatic damage deteriorated. NO donor L-Arg and ET receptor antagonist TAK-044 could alleviate the hepatic I/R injury to some degree, whereas NO synthase inhibitor L-NAME aggravated the damage. It was concluded that the hepatic I/R injury might be related with the disturbance of the NO/ET balance. Regulation of this balance might have an effect on the I/R injury.
