Objective To study the independent risk factors of relapse of smoking among current smokers of different ages who underwent percuta?neous coronary intervention(PCI). Methods Totally 197 current smokers who received PCI from January 2007 to December 2009 in the Fourth Affiliated Hospital of China Medical University were enrolled. Information about relapse of smoking was collected through the medical records and the telephone follow?up. Discrepancy of risk factors of smoking resumption was compared in different age groups. Results Totally 112 patients re?sumed smoking after PCI. There were 87 patients in the non?elderly group and 25 in the elderly group. According to the correlation analysis,more than one stents(P=0.025),severe nicotine dependence(P=0.001)and long time for daily passive smoking(P=0.000)were related with relapse in the non?elderly group,and there was a negative correlation between more than one stents and relapse. But in the elderly group,relapse was associ?ated with history of hypertension(P=0.034). According to the logistic regression analysis in different age groups,independent predictors of smoking relapse in the non?elderly group were severe nicotine dependence(OR:3.914,P=0.003)and long time for daily passive smoking(OR:1.352,P=0.000). And in the elderly group,independent risk factors of smoking relapse were male(OR:17.325,P=0.027),history of hypertension(OR:13.185,P=0.005),long time for daily passive smoking(OR:1.273,P=0.045)Conclusion Independent risk factors of smoking relapse were different in the elderly group and the non?elderly group. In the non?elderly group,these factors were severe nicotine dependence and long time for dai?ly passive smoking. And in elderly group,these factors were male,history of hypertension,long time for daily passive smoking.

Objective We Observed the mobilization effects of autologous circulating blood stem cell by G-CSF in old patients(≥70 years old) with acute myocardial infarction (AMI).Methods 10 old patients with AMI were allocated to receive either inclusive type Granulocyte Colony-Stimulating Factor (G-CSF), or excrete type G-CSF to mobilize the stem cell, with either 300?g/day or 600?g/day. The patients received G-CSF by hypodermic injection, and the duration of applying G-CSF was 5 days. In the process of the mobilization of the circulating blood stem cell, the white blood cell (WBC) and CD34 + cell count in the circulating blood should be observed. Results Prior to applying G-CSF and the 3rd、4th、5th、6th、7th after applying G-CSF, the counts of WBC were 6.75?10 9/L、28.16?10 9/L、34.93?10 9/L、34.40?10 9/L、38.93?10 9/L、21.85?10 9/L; the counts of CD34+ cell were 6.25?10 6、51.10?10 6、92.60?10 6、109.65?10 6、134.69?10 6、45.09?10 6 The peak of curve that WBC and CD34 + cell count changed with applying days was at the 6th .The count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood(r=0.940)Conclusion In old patients with AMI, the mobilized peak of WBC and CD34 + cell counts changed with applying days was at the 6th, and the count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood.

Objective To access the clinical effectiveness and safety of the home-made coronary artery stent - Jin Xin stent.

Results The stenosis was 80～100% before the stents implantation, and 0 after the implantation. There were no abrupt occlusion and thrombosis during the procedure,and no cardiac events during the 6～8 months follow-up. Conclusion Jin Xin Stent is very good at releasing and standing-support. And it can dilate completely. It is safe and effective as an interventional therapy for coronary heart disease.

Objective To observe the safety and feasibility of autologous peripheral blood stem cell (PBSC) transplantation by intracoronory infusion in patients with acute myocardial infarction (AMI).Methods Totally 27 patients with AMI were randomly allocated to receive either inclusive type granulocyte colony-stimulating factor (G-CSF),or excretory type G-CSF to mobilize the stem cells.They received the dose of G-CSF 300-600?g/d by hypodermic injection for 5 days.On the sixth day,PBSCs were separated by Baxter CS 3000 blood cell separator into 50ml suspending liquid.The suspending liquid without treatment was infused into the infarct-related artery (IRA)by occluding the over-the-wire balloon and infusing artery through balloon center lumen.During PBSC mobilization,the following side-effects should be paid attention to,such as bone pain,lethargy,tetter,fever,gastrointestinal effects (nausea,vomiting,constipation),angina or deteriorated heart failure,as well as some rare complications (spontaneous spleen rupture,severe purulent infection, hypercoagulable state,and autoimmune diseases).When the PBSCs were being separated and collected,some complications were observed,for example,low calcium effects (mouth numbness and spasm),pale and dizziness due to vagus reflect,pale and dizziness owing to low blood volume,deterioration of angina or heart failure.The complications should also be observed during the PBSC transplantation by intracoronary infusion:arrhythmia including bradycardia (because of balloon occlusion),sinus arrest or the third degree of atrial ventricular block (because of coronary spasm due to balloon stimulating stent), ventricular fibrillation or hypotension,etc.Results There were 22 cases with complications during the mobilization,separation,collection, and infusion of PBSCs.The incidence of complications during mobilization was 44.4%(12/27),during separation and collection is 25.9%(7/27),and during PBSC transplantation by intracoronary infusion 11.1%(3/27).Conclusion In patients with AMI,Intracoronary infusion of PBSC is feasible and safe.

BACKGROUND: Most of evidence-based studies include both adult degenerative scoliosis and adult idiopathic scoliosis, which lead to indirectness in the results, and suppress the promotion of the evidence.OBJECTIVE: To systematically analyze the current clinical researches, and to review the curative efficacy of lateral lumbar interbody fusion for adult degenerative scoliosis.METHODS: A computer-based research of Medline, EMBASE, CENTRAL, WanFang and CNKI databases from December 2015 to December 2016, was performed with the key words of lateral lumbar interbody fusion, direct lumbar interbody fusion, extreme lateral interbody fusion, minimal invasive surgery, adult scoliosis. The articles were screened based on the inclusion criteria, and the clinical symptom improvement and radiological changes were analyzed.RESULTS AND CONCLUSION: Totally 13 articles were included. In the treatment of adult degenerative scoliosis, lateral lumbar interbody fusion shows less blood loss, short hospitalization time, significantly improved symptoms, satisfactory correction at the coronal plane, and low incidence of long-term complications. However, it has the poor correction at the sagittal plane and high incidence of short-term postoperative complications. Therefore, intraoperative neurologic monitoring is necessary and the combination with internal fixation has obtained good effectiveness.

Objective To observe the therapeutic effect of balloon dilation in acute thrombus disease. Methods After coronary angiography, 137 patients with acute thrombus disease who were performed percutaneous coronary artery interventional therapy (PCI) from August 2010 to August 2012 were enrolled. In them, 53 patients (control group) didn′t undergo balloon dilation after PCI, and 84 patients(observation group)underwent balloon dilation after PCI. The intraoperative complications and the major adverse cardiac events (MACE) rate were observed. Results The rate of residue stenosis in observation group was lower than that in control group:(6.7 ± 1.3)% vs. (17.1 ± 1.8)%, and there was significant difference (P<0.05). The operation time in observation group was higher than that in control group:(57 ± 26) min vs.(48 ± 32) min, and there was significant difference (P<0.05). The no-reflow or slow flow after PCI in observation group was 3.8%(2/53), in control group was 3.6%(3/84), and there was no significant difference (P>0.05). The follow-up time was (0.9 ± 0.2) years. In control group, myocardial infarction occurred in 2 patients, 7 patients reviewed coronary angiography, and 2 patients underwent revascularization. In observation group, there was no MACE. Five patients reviewed coronary angiography, and no patient underwent revascularization. Conclusions The method of balloon dilation after PCI in acute thrombus disease is safe and feasible. It can reduce the incidence of MACE, and did not increase the rate of no-reflow or slow flow.

Objective To investigate the efficacy of intracoronary tirofiban during percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Seventy-six consecutive AMI patients,treated with primary coronary angioplasty in 12 hours were enrolled.They were randomly divided into two groups:tirofiban group(39 cases)and control group(37 cases).Tirofiban group was treated with intracoronary timfiban during PCI and after the operation for 48 hours.Both of them were given heparin in PCI and aspirin,clopidogrel before PCI.At the end of PCI procedure,angiographic features such as TIMI flow grade and TIMI myocardial perfusion grade(TMPG)were analyzed.The difference of two groups in complication and major adverse cardiac events(MACE) was investigated.Results The myocardial reperfusion of tirofiban group was better than that of control group[TIMI grade 3 flow 94.9%(37/39) vs 78.4%(29/37),P<0.05;TMPG 3 grade 89.7%(35/39)vs 67.6%(25/37),P<0.05].There was no significant difference between two groups in bleeding complication.The occurrence of MACE in tirofiban group was less than that in control group[7.7%(3/39)vs 18.9%(7/37),P<0.05].Conclusion Intracoronary tirofiban dunng primary PCI in patients with AMI can improve coronary flow and myocardial perfusion,and has no more bleeding and less MACE occurrence.

Objective To evaluate the efficacy and safety of direct stenting technique in emergent percutaneous coronary intervention(PCI)for pa?tients with acute myocardial infarction(AMI). Methods Totally 460 consecutive patients with acute myocardial infarction who underwent emergent PCI during August 2010 to July 2013 were involved,among whom 346 patients were assigned to the control group(traditional balloon dilation and stenting),114 patients were assigned to the experiment group(direct stenting). The safety and efficacy of direct stenting technique was observed. Results In the control group,7 cases had no reflow during operation,2 cases had reflow after the pre?expansion and 5 cases after stent implanta?tion,no similar cases in the experiment group(P=0.125 9). The follow?ups showed the control group had 2 cases of major adverse cardiac events including 1 case of acute stent thrombosis who required urgent revascularization,and 1 case of cardiac death at four days after operation;the experi?ment group had 1 case of stent thrombosis,there was no statistically significant difference(P=0.730 7). Conclusion Direct stenting technique may be performed selectively for certain coronary diseases when performing emergent PCI for AMI.

Objective To detect brain structural difference between children with unexplained mental retardation and children with typically normal development. Methods The high-resolution magnetic MR imaging were obtained from 21 children with unexplained mental retardation and 30 age-matched control children without intellectual disabilities. Voxel-based morphometry analysis with an optimization of spatial segmentation and normalization procedures were applied to compare differences of gray matter volume between the two groups. The total and regional gray matter volume were compared between the two groups with independent t test. Meanwhile, correlation was conducted to analyze the relationship between the total gray matter volume and intelligence quotient (IQ) with partial correlation test. Results The total gray matter volume was significantly increased in the mental retardation children [(1. 012 ±0. 079) × 106 mm3]in relative to the controls [(0. 956 ± 0. 059) × 106 mm3, t = - 2. 80, P ＜ 0. 05]. Compared to controls,children with unexplained mental retardation showed significantly increased gray matter volume in different regions, including the bilateral thalami, the bilateral superior frontal gyri, the bilateral gyri rectus, the bilateral temporal poles, the right inferior frontal gyrus, right parahippocampal gyrus and the right cerebellum. No correlation was detected between the total gray matter volume and IQ in children with mental retardation (r = 0. 078 ,P ＞ 0. 05). Conclusions VBM would detect the gray matter abnormalities that were not founded in routine MR scanning. The increase of gray matter volume in the frontal-thalamus network might indicate the delayed maturation of the brain development. This might be one of the causations of mental retardation in children.
