Objective To evaluate the difference in coronary microcirculation and short term prognosis in patients with different collateral circulation and underwent elective percutaneous coronary intervention ( PCI) with complete occlusion of coronary artery. Methods The study included 42 patients who had been admitted in our hospital for NSTEMI or STEMI between 01/2012 to 12/2015 without receiving revascularization treatment and whose symptoms persisted for over 6 months. According to the results of coronary angiography and the Rentrop grade, the patients were divided into 2 groups: poor collateral circulation formation group (group A, Rentrop=0 -1, n=17) and well established collateral circulation group (group B, Rentrop=2-3, n=25). The basic clinical data and the result of coronary angiography were compared. A pressure-temperature sensor wire was used to measure index of mierocirculatory resistance ( IMR) immediately after PCI. An echocardiograph was used to measure left ventricular end systolic diameter ( LVEDd) and left ventricular ejection fraction ( LVEF) postoperatively and again at 3 months after operation to evaluate the changes in cardiac function. Results The IMR value of group A was significantly higher than group B (P﹤0. 05), the grade of collateral circulation had negative correlation with IMR value (r=-0. 671, P﹤0. 05). The mean changes in LVEDd in 3 months in group B was -0. 28 mm, while in group A was 5. 76 mm (P﹤0. 05). The mean changes in LVEF in 3 mouths in group B was 5. 36% and in group A was -3. 82% (P﹤0. 05). The grading of coronary collateral circulation had negative correlation with the changes of LVEDd in 3 months (r= -0. 669, P﹤0. 05), but had positive correlation with the changes of LVEF (r=0. 657, P ﹤0. 05). The IMR value had positive correlation with the changes of LVEDd in 3 months (r=0. 686, P﹤0. 05), but had negative correlation with the changes of the LVEF (r= -0. 664, P﹤ 0. 05 ) . Conclusions Patients with poor collateral circulation was more prone to coronary microcirculatory injury than patients with good collateral circulation. Patients with good collateral circulation and microcirculation had better prognosis after the revascularization of the infarction-related vessel.

Objective To explore if any rules in electrocardiogram changes after transcatheter closure of perimembranous ventricular septal defects ( PMVSD ) . Methods We included all the 358 patients who have accepted transcatheter closure of PMVSD in our hospital between July 2006 to October 2014 and the electrocardiogram (ECG) done in hospital and during follow up in 1,3, 6 and 12 months after operation were all reviewed. Results No changes were found in heart rates and electrical axis during follow-up as compared to preclosure ECG. PR interval was shorter, the QRS duration and QT interval were longer than preclosure. Incidence rate of arrhythmia was 38. 0% ( 136/358 ) and incidence rate of serious arrhythmias ( including Ⅱ° or Ⅲ° atrioventricular block and complete left bundle branch block) was 5. 0%(18/358). Among the 180 patients who had ECG done in all follow up between the first 12 months post closure, the rates of new developed arrhythmias was 12. 8% ( 23/180 ) and severe arrhythmia was 0. 6%(1/180) during follow-up. Conclusions Incidence rate of serious arrhythmias after transcatheter closure of PMVSD is low and most patients have good clinical outcome.

OBJECTIVE To explore the origin and morphological features of small supernumerary marker chromosomes (sSMCs) in Turner syndrome. METHODS For 5 cases of Turner syndrome with a sSMC identified by conventional G-banding, dual-color fluorescence in situ hybridization (FISH) was applied to explore their origin and morphological features. RESULTS Among the 5 cases, 3 have derived from the X chromosome, which included 2 ring chromosomes and 1 centric minute. For the 2 sSMCs derived from the Y chromosome, 1 was ring or isodicentric chromosome, while the other was an isodicentric chromosome. CONCLUSION The sSMCs found in Turner syndrome have almost all derived from sex chromosomes. The majority of sSMCs derived from the X chromosome will form ring chromosomes, while a minority will form centric minute. While most sSMC derived from Y chromosome may exist as isodicentric chromosomes, and a small number may exist as rings. For Turner syndrome patients with sSMCs, dual-color FISH may be used to delineate their origins to facilitate genetic counseling and selection of clinical regime.
