Chinese Circulation Journal 2015;30(5):446-448
Objective: To explore the clinical value of N-terminal Pro-brain natriuretic peptide (NT-ProBNP) and cardial troponin I (cTnI) for evaluating the patients with acute pulmonary embolism (APE) combining right ventricular dysfunction (RVD). Methods: A total 92 APE patients treated in our hospital were studied. The blood levels of NT-ProBNP and cTnI were measured on next morning of administration and echocardiography was performed within 24 hours of APE diagnosis. According to echocardiographic results, the patients were divided into 2 groups: APE with RVD group,n=47 and APE without RVD group,n=45. Blood levels of NT-ProBNP and cTnI were compared between 2 groups. Results: Compared with APE without RVD group, APE with RVD group presented increased levels of NT-ProBNP, cTnI and right ventricular end-diastolic diameter (RVEDD), allP<0.01. ROC curve analysis found that both AUC of NT-ProBNP and cTnI > 90%, the optimum operating point for NT-ProBNP and cTnI were 554 pg/ml and 0.09 ng/ml respectively. Logistic regression analysis showed that NT-ProBNP (r=1.227,P=0.005), cTnI (r=0.862,P=0.016), right ventricular dysfunction (r=0.936,P=0.008) and heart rate (r=0.809,P=0.023) were related to poor prognosis for in-hospital patients. Conclusion: Blood levels of NT-ProBNP and cTnI may help diagnosing the patients with acute pulmonary embolism with right ventricular dysfunction, it may also predict the short term prognosis in clinical practice.

Objective To study the mechanism of miR?200c in regulating RMP7?induced increases of blood?tumor barrier(BTB)permeability by targeting Ras homolog gene family member A(RhoA). Methods Endogenous expression of miR?200c was detected by real?time PCR in hu?man cerebral microvascular endothelial cell line hCMEC/D3(ECs)after RMP7 treatment. miR?200c mimic and miR?200c inhibitor were transfect?ed into GECs(ECs with U87 glioma cells co?culturing),respectively. Transfection efficiency of miR?200c mimic and miR?200c inhibitor were de?termined by real?time PCR. HRP flux and TEER assays revealed BTB permeability. The protein expression level of RhoA was assessed by West?ern blotting. The distribution of RhoA was assessed by immunofluorescence microscopy. RhoA luciferase assays were performed using the Dual?Lucif?erase reporter assay system. Results RMP7 significantly induced a decrease in miR?200c expression in GECs of BTB. miR?200c mimic and miR?200c inhibitor were successfully transfected into GECs. Overexpression of miR?200c inhibited endothelial leakage and restored normal transendo?thelial electric resistance values. Simultaneously ,overexpression of miR?200c significantly reduced the protein expression level of RhoA. In addi?tion,immunofluorescence analysis revealed that the distribution of RhoA in the cytoplasm and nuclei of GECs were decreased in miR?200c mimic group. RhoA was one of the direct targets of miR?200c with the specific binding site being located at the seed sequence. The results of miR?200c si?lencing were opposite to that of the miR?200c overexpression group. Conclusion miRNA?200c regulated RMP7?induced increases in BTB perme?ability by targeting RhoA.

Objective: To study the effects of Gentianae Macrophyllae Radix in cold and heat compatibility in rheumatic fever arthralgia rheumatoid arthritis (RA) model rats by principal component analysis and cluster analysis. Methods: Eighty SD rats were randomly divided into blank group, collage II model group, rheumatic fever arthralgia model group, tripterygium group, single Qinjiao group, Qinjiao-Weilingxian (Clematidis Radix et Rhizoma) group, Qinjiao-Sangjisheng (Taxilli Herba) group, and Qinjiao-Fangji (Stephaniae Tetrandrae Radix) group; rheumatic fever arthralgia model were induced by collage II and being exposed in rheumatic fever environment, each administration group was gavaged with 15 mL/kg corresponding drug solution after modeling. The weight, paw thickness, arthritis index, pain threshold, cold pain tolerance time and pressure pain tolerance value were measured. The serum contents of RF, CRP, TNF-α, IL-1β, and PGE2 were detected by ELISA. Results: Principal component analysis selected two principal components, which carried 89.6% of the original information, the first principal component reflected all information in expect weight, the second principal component mainly reflected the weight. The total factor score F (the greater the F value, the more severe the disease) was obtained by the sum of the principal component factor score and its weight (variance contribution) product. The F value of rheumatic fever arthralgia model group was the highest and the score of the blank group was the lowest, the F value of Qin-Fang group was significantly lower than those of Qin-Wei group and Qin-Sang group. Cluster analysis divided eight groups into three categories according to the blank, model and administration, which was consistent with the theory; In the control group, Qin-Fang group was clustered into one group, and the other groups were clustered into one group. Conclusion: For the rheumatic fever arthralgia RA, the combined effect of mild and cold traditional Chinese medicine (TCM) is better than the combined effect of mild and warm TCM and the combined effect of mild TCMs. Experimental results are consistent with the principles of TCM clinical treatment of "treating the hot diseases should use the cold medicine"; Principal component analysis and cluster analysis are simple and reliable, and can be used to evaluate the animal model and drug efficacy.
