Objective To evaluate the effects of recombinant human hematopoietic synergistic factor (rhHSF) on rapid mobilization of the peripheral blood stem cells. Methods 8 monkeys were divided into rhG-CSF 10?g/(kg?day) and rhG-CSF 10?g/(kg?day) + rhHSF 500?g/(kg?day) group, with 4 monkeys in each group. All of them received rhG-CSF subcutaneously once daily for 4 days, and in the latter group, the animals received rhHSF subcutaneously in single dose on the fifth day. Results The highest counts of CD34~+ cell, CFU-GM and neutrophils in animals receiving rhHSF only were 23, 1.8 and 3.3 times of baseline value at 180, 45 and 60 min, while those in animals receiving rhG-CSF and rhHSF were 41.3, 8.3 and 4.9 times of base line value. Conclusion rhHSF can rapidly mobilize hematopoietic stem cells and neutrophils into peripheral blood, and it is found to synergize with G-CSF to augment stem cell mobilization, suggesting a potent clinical utility of rhHSF in peripheral blood stem cells transplantation.

Objective To evaluate the effect of homemade tirofiban in percutaneous coronary intervention for acute myocardial infarction. Methods Sixty four cases of consecutive acute myocardial infarction were enrolled and divided into two groups: the tirofiban group (n=34) and the control group (n=30). In addition to intravenous heparin, patients in the tirofiban group received a bolus dose of tirofiban (10 ?g/kg) before stenting and followed by a 0.15 ?g/(kg?min) infusion for up to 12-36 hours. The control group only receive routine intravenous heparin therapy before and during PCI. The post operation TIMI blood flow, bleeding events and major adverse cardiac events were observed in the 2 groups. Results A 97.1% of patients in the tirofiban group compared with 76.7% in the control group obtained TIMI grade 2-3 flow respectively. Among them, 91.2% in the tirofiban group but 70.0% in the control obtained TIMI 3 flow. There were no serious in-hospital bleeding complications and MACE. Conclusion Homemade tirofiban is effective in improving the TIMI grade and prognosis of acute myocardial infarction after PCI.

Objective To study the changes of left ventricular structure and function after transcatheter closure of atrial septal defect(ASD)by strain rate(SR)imaging.Methods Twenty-eight patients with secundum type ASD were undergone transcatheter closure.Left and right ventricular end-diastolic diameter(LVED and RVED),left ventricular ejection fraction(LVEF),the Doppler transmitral filling velocities(E values and A values)and tricuspid regurgitation pressure were measured respectively at pre-operation,3 days,1 month and 3 months of post-operation.According to tricuspid regurgitation pressure,systolic pulmonary artery pressure(SPAP)was estimated.SR curves in all segments of left ventricular walls were acquired for all patients.The SR values including the peak of systolic SR,early-diastolic SR,late-diastolic SR were measured respectively.ResultsAfter operation,LVED,LVEF,E values and A values increased significantly while RVED and SPAP decreased.Almost all left ventricular walls' SR increased at post-operation except that SR of interventricular septeum(IVS)and left ventricular post wall(LVPW)decreased at 3 days,1 month of post-operation.Conclusions LV systolic and diastolic function are improved after operation,but SR characteristic changes of IVS and LVPW is the one of the most unique characters.

Objective To evaluate the therapeutic effects of rAAV2-SERCA2a gene targeted to myocardium by the ultrasound mediated microbubbles in rats with myocardial infarction(MI) using speckle tracking echocardiography (STE). Methods Thirty-five male SD rats were divided into Sham group, MI group and gene therapy group. rAAV2-SERCA2a was attached to the surface of SonoVue, sulphur hexafluoride-filled microbubbles. Therapy group animals were infused with those mixed fluids through tail vein. The other two groups were infused with SonoVue microbubbles. These bubbles were infused with simultaneous echocardiography. Four weeks after ultrasound microbubbles destructed,Circumferential strain rate(SRcir), radial strain rate(SRrad) and left ventricular torsion (LVtor) of regional myocardium were measured in short-axis view using speckle tracking imaging software for each animal. Results Compared with the M1 group,there were significant increase in SRcir-S,SRcir-E, SRrad-S,SRrad-E and LVtor in rats of gene therapy group( P ＜0. 01 ). There was no significant difference between gene therapy group and sham group. Conclusions rAAV2-SERCA2a gene targeted to myocardium by the ultrasound mediated microbubbles could enhance cardiac function of rats with MI.

Objective To evaluate left atrial appendage regional function and movement changes of systolic and diastolic in patients with atrial fibrillation by speckle tracking imaging(STI) and real-time three-dimensional transesophageal echocardiography(RT-3D TEE).Methods Sixty-seven patients underwent RT-3D TEE was divided into 24 controls,22 paroxysmal atrial fibrillation,21 persistent atrial fibrillation.Left atrial appendage was divided into basal,middle and apical segment.Left atrial appendage emptying fraction of the overall (LAA-EF),basal emptying fraction (B-EF),middle emptying fraction (M-EF) and apical emptying fraction (A-EF) was measured by three-dimensional volume measurement.Each segment systolic strain rate (SRS) and diastolic strain rate (SRD) was measured by STI.Results LAA-EF,B-EF,M-EF,A-EF of paroxysmal atrial fibrillation and persistent atrial fibrillation group were lower than those of the control group,and persistent atrial fibrillation group was the lowest in the three groups.Compared with the control group,SRS and SRD of left atrial appendage basal,middle,apical segment was lower in paroxysmal atrial fibrillation group and persistent atrial fibrillation group,and persistent atrial fibrillation group decreased more significantly.Conclusions Paroxysmal atrial fibrillation and persistent atrial fibrillation can lead to left atrial appendage global or local systolic and diastolic function to reduce,and persistent atrial fibrillation decreased more significantly.

Objective: To detect the changes of serum level of connective tissue growth factor (CTGF) in patients with ST-segment elevation myocardial infarction (STEMI) and to study the correlation between CTGF level and the maximal activity of creatine kinase-MB (CK-MB). Methods: Our research included 2 groups of patients: STEMI group and unstable angina (UA) group. All patients were treated in our hospital from 2013-07 to 2014-06,n=50 in each group. In STEMI group, the serum levels of CTGF were examined by ELISA at 24h, 2, 7, 14 days of onset, and in UA group, CTGF level was examined at 24h of onset. The CK-MB activity levels were measured in STEMI group at the same time points by immunosuppression method. Results: The serum level of CTGF in UA patients at 24 h of onset was (10.34 ± 2.00) ng/mL, and in STEMI patients were (16.76 ± 3.17) ng/mL at 24h, (29.87 ± 4.90) ng/mL at 2d, (45.02 ± 8.35) ng/mL at 7d and (31.61 ± 4.40) at 14d. The CTGF levels in STEMI group at different time points were all higher than UA group at 24h of onset,P<0.01. In STEMI group, the CTGF levels were increasing from 24h to 7d, then decreasing at 14d, allP<0.01. In STEMI group, the highest protein concentration of CTGF was positively related to the maximal activity of CK-MB at 7 days of onset (r=0.859,P=0.000). Conclusion: CTGF expression has been up-regulated in STEMI patients which might be related to myocardial ifbrosis. The protein level of CTGF is related to MI size, it shows certain predictive value in relevant patients.
