Objective To quantitatively analyze the coronary artery ostia by three-dimensional trans-esophageal echocardiography (3D-TEE).Methods The full-volume images of aortic root and coronary artery ostia were acquired by 3D-TEE in 95 adult patients.The Philips QLab 3DQ measurement technology was employed to determine three mutually perpendicular planes:(1) The transverse plane cross the bottom of three coronary artery sinus.(2) The sagittal plane perpendicular to sino-tubular junction.(3) The coronal plane perpendicular to the aforementioned two planes .The following relevant parameters were measured and recorded:(1) Length, width, height and area of bilateral coronary artery ostia .(2) The angle between coronary arterial outflow tract and aortic root in sagittal plane .(3) The spatial distribution of coronary artery ostia, aortic root and coronary artert sinus .Results The shape of left coronary artery ostia were more regular (round or oval) than right coronary artery ostia ( teardrop-shape or oval ).Calcification was more frequent in right coronary artery ostia (81/95, 85.26%) than that in left coronary artery ostia. There were statistical differences between left and right coronary artery in the parameters of ostial wide , area and height (t =3.85, 3.86, -4.49, all P<0.01).Most left coronary artery ostia were located inside the sinus (76/95, 80.00%), mainly in the upper third segment (69/95, 72.63%); while more than half of the right coronary artery ostia were found outside the sinus ( 53/95, 55.79%).The difference was statistically significant( χ2 =25.91, P<0.01).Conclusion The quantitative analysis of aortic root and coronary artery ostia based on the full-volume images originated from real-time 3D-TEE is feasible, which is helpful for further clinical research .

Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

Objective: To analyze the clinical features and outcomes of cardiac resynchronization therapy (CRT) in patients with dilated-phase hypertrophic cardiomyopathy (DHCM). Methods: A total of 16 DHCM patients received CRT in our hospital from 2007-03 to 2016-01 were retrospectively studied to analyze their clinical features and outcomes. Results: There were 12 male and 4 female patients at the mean age of (53.3±13.5) years. Pre-operative QRS duration of ECG was (158.7±32.2) ms, left ventricular ejection fraction (LVEF) was (33.6±6.3) %, the patient with NYHA class I, II, III and IV were 1, 5, 8 and 2 respectively. 13 patients received new CRT device, 3 received upgraded device and 8 (50%) combining atrial fibrillation (AF). The patients were followed-up for (2.56±2.13) years, 5 of them died including 3 of heart failure, 1 of sudden death and 1 of stroke. At 6 months follow-up time, 7 patients had the response to CRT which was defined by the improvement of NYHA class≥1 and the absolute elevation of LVEF≥5%; NYHA class improved from (2.69±0.79) to (2.38±0.89), P=0.02; LVEF increased from (33.6±6.3) % to (40.03±9.83) %, P=0.01. Conclusion: DHCM patients with CRT indication had the higher incidence to suffer from AF, those were more in patients with traditional pacemaker or ICD upgrading. DHCM patients with CRT had the poor general prognosis, while there was still certain proportion of patients had the response to CRT.

The glycosylation heterogeneity of recombinant human pro-urokinase (pro-UK) was assessed using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS). Firstly, the source of heterogeneity was determined by measuring the M_r of intact protein before and after N-deglycosylation. Glycosylation sites and the proportion of O-glycopeptides then were determined at the peptide level. Finally, the N-glycans were confirmed and quantified using the N-glycan profile. Results show that the structural heterogeneity of pro-UK is mainly caused by glycosylation. All T₁₈ were fucosylated, and 6.4% of S_138/139 was O-glycosylated with two kinds of oligosaccharides with a ratio of 6.0% and 0.4% respectively. All N₃₀₂ positions were N-glycosylated by more than ten types of glycans, among which A2F and A3F accounted for 80% of the total. The assessment of glycosylation heterogeneity of pro-UK will provide a reference for quality standardization.

OBJECTIVETo optimize extraction and purification methods of acidic polysaccharide from Moerella iridescens (MIAP).

METHODSWith alkali extraction process and orthogonal experiment,the time consumption,temperature,pH value of the solution and alcohol concentration during the extraction were optimized. The crude products were deprived of protein,pigment and ion,then were purified with DEAE-cellulose ion-exchange chromatography and verified with Sephadex G-100 and cellulose acetate membrane electrophoresis,and examined with infrared spectrum.

RESULTSThe optimized extraction conditions were as follows: extraction time 6 h,extraction temperature 70 degree,the solution pH 8.0 and the concentration of alcohol precipitation 70%. Intuitive features showed that the MIAP was pure white crystalline granular with slight dark brown color. The purification results demonstrated that the target MIAP was eluted and identified as a homogeneous components by DEAE-cellulose ion exchange column,Sephadex G-100 and cellulose acetate membrane electrophoresis. Infrared spectral scanning suggested that MIAP was α-D-type terminated glucopyranose. Intuitive features showed that MIAP was soft and cottony white.

CONCLUSIONThe extraction process with orthogonal test has been optimized and the acidic polysaccharide from Moerella iridescens is successfully isolated.
