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.

Intracranial atherosclerotic stenosis (ICAS) is an important cause for the occurrence,development,and recurrence of ischemic stroke.Age,hypertension,diabetes,and smoking etc.are its traditional risk factors.Among them,symptomatic ICAS is the key of clinical intervention.Its treatments include intensive medical therapy,endovascular treatment,extracranial intracranial arterial bypass grafting,encephaloduroarteriosynangiosis,and external counterpulsation,etc.

Lynch syndrome.(LS) is an autosomal dominant condition caused by a mutation in the mismatch repair genes (MMR).Endometrial cancer (EC) is the most common extra-colonic cancers of LS Ⅱ type.Among the female members of LS family with the MMR gene mutation,EC has an overall lifetime risk more than 35％.LS-associated EC is more likely present as the clinical pathological characteristics of early age of onset,endometrioid adenocarcinoma,lower grade,lower uterine segment involvement,and better prognosis.LS patients with family history and early age of onset should be performed with a combined screening and genetic testing,while high-risk patients should be taken clinical monitoring methods as endometrial biopsy.Oral contraceptives mav be reasonable chemopreventive agents in the patients with LS.Although prophylactic hysterectomy with bilateral salpingo-oophorectomy is an effective strategy to prevent EC in women with LS,preoperative counseling should address the trade-offs between the reduction in the risk of cancer,and the risks and side effects of surgery.The patients need hormone replacement therapy after surgery.

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 detect the expressions of circulating microRNAs (miRNAs) of peripheral whole blood in Alzheimer's disease (AD) and investigate the potential roles of the miRNAs as diagnostic bi omarkers for Alzheimer's disease.Methods Peripheral blood samples were obtained from 110 AD patients and 150 age-and gender-matched normal controls.The concentrations of seven candidate miRNAs,including miR-9,miR-29a,miR-29b,miR-101,miR-181c,miR-137and miR-126,were measured with a real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method.The data of two groups were collected and analyzed by SPSS 19.0 software.Results It was found that miR-29a (P=1.12×10-5) and miR-101 (P=6.24× 10-7) were markedly down-regulated in peripheral blood of AD patients compared with normal controls.In addition,logistic regression analysis revealed peripheral whole blood miR-29a/101 combination could be a potential biomarker of AD with better specificity (82％) and sensitivity (75％).Conclusions miR-29a/101 combination in peripheral whole blood may serve as a useful noninvasive diagnostic biomarker for AD.

OBJECTIVETo investigate the genome structure variation (SV) related with keloid using the whole-gene resequencing technology.

METHODSWe studied a keloid pedigree containing 4 generation of 27 people. 5 people (4 cases of keloid patients, and 1 case of normal) were selected to extract the genomic DNA. Then the whole-gene resequencing technique was used to check the variations.

RESULTSThrough database comparison and variation annotation analysis, we obtained 2 SVs associated with keloid formation. We used DAVID software to do the gene ontology and pathway analysis. We found a 168 bp inversion in gene tetraspanin 8 (TSPAN8) in all keloid patients, which contained the forth exon of TSPAN8.

CONCLUSIONSThere was no report about SVs related to keloid. In this study, we found 2 SVs associated with keloid, especially TSPAN8. The tumor cells express the TSPAN8 can up-regulate the vascular endothelial growth factor and its receptors, promote the adjacent fibroblasts secrete matrix metalloproteinases and uridylyl phosphate adenosine. So we hypothesis that the inversion of the forth exon in TSPAN8 may lead to the signal transduction disorder in the keloid patients. This study was a preliminary research. It needs a further study containing large sample to confirm.

Objective To investigate the long-term results of gastrocnemius fascial turn-down flaps and suture anchors in reconstruction of chronic Achilles tendon rupture.Methods From September 2007 to February 2010,20 patients with chronic Achilles tendon rupture were reconstructed with gastrocnemius fascial turn-down flaps plus suture anchors.There were 13 males and 7 females at mean age of 36 years (range,23-50 years).Unilateral tendon rupture was observed in 19 patients and bilateral in 1 patient.Tendon defect gap was 5-9 cm (mean 6.7 cm).Braces were used to immobilize the lower limber,and early exercise was encouraged.The outcomes were assessed using Arner-Lindhohm scoring system and Leppilahti scoring system.Results Postoperative recovery was uneventful.No patients experienced cut infection or other complications.After a mean 38-month follow-up (range,30-42 months),all patients could stand on the injured toes.Muscular strength of the affected lower limber was restored to 89％ of the unaffected side.According to the Arner-Lindhohm score,10 patients were rated as excellent and ten good.Mean Leppilahti score was 85 points (range,60-100 points),with excellent results in nine patients,good results in 10 and fair result in one.Conclusion For patients with chronic Achilles tendon rupture,the reconstructing using gastrocnemius fascial turn-down flaps combined with suture anchors can attain rigid fixation,early functional exercise,effective prevention of tendon adhesion,and good function recovery.
