Objective To investigate the alternation of left ventricular systolic function in patients underwent transcatheter aortic valve implantation operation(TAVI) by three-dimensional speckle tracking technology (3D-STI).Methods Totally 20 patients with severe aortic stenosis were enrolled.All the subjects underwent successful TAVI operation.The real-time 3D full volume datasets on apical four-chamber view were acquired on before,7 days and 1 month after TAVI.Left ventricular global longitudinal strain(GLS),regional peak systolic longitudinal strain(LS),regional peak systolic circumferential strain(CS) and regional peak systolic radial strain(RS),were analysed using off-line TomTec software,the differences among the three groups were compared.Results Compared with the preoperation,aortic valve blood flow velocity (AV),mean aortic valve pressure gradient(mPAG) of 7 days after operation decreased significantly.Threedimensional left ventricular ejecation fraction(3D-LVEF) among the patients whose 3D-LVEF under 50％had a remarkable increase and whose 3D-LVEF exceed 50％ before operation had no significant change,while 1 month after operation the 3D-LVEF had a significant improvement compared with the preoperational data regardless of 3D-LVEF under 50％ or not.The GLS and LS of all segments of 7 days after TAVI were higher than pre-operation(all P ＜0.05),and it had a further improvement 1 month after TAVI.Conclusions LV systolic function had improvement early after TAVI.3D-STI is a new,convenient way to detect the global and regional left ventricular systolic function of TAVI patients.

Objective To investigate the micminnammatory state and its relationship with atherosclerosis and cardiac function in patients on continuous ambulatory peritoneal dialysis(CAPD). Methods Sixty-seven CAPD patients,27 non-dialytic stage 5 chronic kidney disease(CKD 5)patients and 27 gender and age matched healthy controls wore enrolled in this cross-sectional study.Clinical data and biochemical parameters were collected.Serum interleukin-6(IL-6)and IL-10 levels were measured by enzyme-linked immunosorbent assay(ELISA).High-sensitivity C-reactive protein(hs-CRP)was measured by immunoturbidimetry.Prevalence of atherosclerosis was detected by carotid uhrasonography while cardiac function was detected by echocardiography. Results Serum levels of inflammatory biomarkers were elevated significantly in CAPI)and CKD 5 patients as compared with healthy controls[IL-6(ng/L):2.400,1.515 vs 0.698;IL-10(ng/L):1.988,1.958 vs 0.277;hs-CRP(mg/L):1.090,1.345 vs 0].Left ventricular mass index(LVMI),myocardial performance index(Tei index 0.75±0.31,0.66±O.27 vs 0.52±0.23)in CAPD and CKD 5 patients increased significantly.The prevalence of carotid artery atherosclerosis and left ventricular hypertrophy(LVH)in CAPD and CKD 5 patients was significantly higher than that in healthy controls.No significant difference of the ultrasonic parameters was found between CAPD and CKD 5 patients.In CAPD patients,IL-6 was positively correlated with Tei index,whereas IL-10 was negatively correlated with INMI and was positively correlaled with ejection fraction(EF).In a multiple regression model,IL-6,self-rating depressive scale(SDS)score and pulse pressure were independent predictors of carotid artery atherosclerosis.Similarly,IL-6 and primary hypertension were independent correlates of Tei index in CAPD patients. Conclusions Microinflammatory state exists in either non-dialytic CKD 5 patients or CAPD patients and it is associated with atherosclerosis and cardiac distunetion.IL-6 is an independent risk factor of atherosclerosis and increased Tei index in CAPD patients.

Objective To investigate the effect of endoscopic management of upper tract urothelial carcinoma (UTUC),and evaluate the indication and clinical value of postoperative prophylactic pelviureteric instillation chemotherapy.Methods Patients who met the inclusion criteria included elderly patients,patients who could not tolerate radical surgery,patients with renal insufficiency or needed dialysis after removal of the kidney,patients with bilateral UTUC,patients with tumor≥3 cm in diameter but could be completely resectted under ureteroscopy who required to preserve renal function.Surgical procedure was successful.The ureteral stents were placed,and prophylactic ureteral infusion chemotherapy via the retrograde transvesical ureteric catheterisation was conducted 1-2 times one week at 2 days after surgery.40 milligram of pirarubicin hydrochloride or epirubicin hydrochloride was dissolved in 40 milliliter sterile water for the prophylactic infusion chemotherapy.These instillations were completed within 40 minutes.Results Totally,9 patients (3 males and 6 females) aged 60-86 years,mean age of (69.7±6.4) years,were enrolled in this study.The carcinoma of the renal pelvis was found in 2 cases and ureteral tumors in 7 cases.In pathological results,ureteral polyps was found in 1 case,papillary ureteral neoplasm with low malignant potential in 2 cases,urinary tract epithelial carcinoma in 4 cases (1 case with poorlydifferentiation,1 case with well-differentiation,2 cases with urinary tract epithelial cancer),and 2 cases were lack of pathological reports because of too few pathologic specimens.4 patients received adjuvant chemotherapy by instillation successfully,and lumbago,fever or other complications were not found.Patients were followed up for a mean period of 15 moths (4-31 months).Only 1 patient had recurrence of bilateral ureteral tumor 15 months after surgery,and no tumor recurrence was found in other patients.Conclusions Endoscopic management is a safe and effective in treating UTUC,which can preserve renal function by avoiding nephrorectomy in some patients.The instillation chemotherapy after endoscopic management is safe,which has a satisfactory effect,but further validation in a large clinical sample is needed.Patients with tumor resection under ureteroscopy who cannot obtain the pathology results need to be closely followed up.

Objective To establish the early warning model for apostasis of postoperative patients with cerebral tumor, predict the risk of apostasis, so as to realize the early control and prevention. Methods Nine hundreds and ninety-five cerebral tumor patients were enrolled in a prospective investigation, the clinical data were collected and analyzed to make the early warning model by Logistic regression analysis. Results Collected 995 valid questionnaires, 149 cases(15.6%, 149/995) need unplanned transfer to ICU, 50 cases(5.0%, 59/995) need unscheduled second operation. The early warning model was established by Logistic regression analysis based on pupil, Glasgow Coma Scale(GCS) score, Modified Early Warning Score(MEWS) three indicators associated with disease progression:Z=0.1×pupil+0.8× GCS score+2.5×MEWS.Then the effectiveness of the model was verified by ROC curve, and the results showed that the area under the curve was 0.852(95%CI 0.816-0.887), sensitivity was 80.5%, specificity was 80.5%, accuracy was 85.0%, Youden index was 0.61, positive likelihood was 4.128, negative likelihood was 0.242. Conclusions The early warning model can predict the apostasis events of postoperative patients with cerebral tumor, also can prevent the complications and improve the quality life of patients.

Objective · To study the metabolite profiles on patients of ischemic stroke using metabonomics approach. Methods · The serum samples from the 29 patients with ischemic stroke and 31 healthy controls were analyzed by gas chromatography time-of-flight mass spectrometry (GC-TOFMS) coupled multi-dimensional statistical methods to find differential metabolites in two groups. Results · Orthogonal partial least squares analysis (OPLS) model was generated based on identified metabolites and shown clear discrimination from patients and healthy controls. Some serum metabolite levels were significantly altered in patients. Six up-regulated metabolites included γ- aminobutyric acid, glutaric acid, glyceric acid, gluconic acid, lactobionic acid, and cholesterol, and nineteen down-regulated metabolites included citric acid, aconitic acid, malic acid, succinic acid, β-alanine, and glycerol-3-phosphate. Conclusion · Amino acid metabolism, glycometabolism and tricarboxylic acid (TCA) cycle are disturbed in patient of ischemic stroke. The metabonomic approach has great potential to understand the underlying mechanisms of stroke in ischemic patients.
