ObjectiveTo investigate the karyotypes of amiotic fluid cells and compare the incidence of chromosomal abnormality as well as to evaluate the clinical significance of abnormal karyotypes. MethodsA total of 13 648 pregnant women came to Shanghai Jiai Genetics and IVF Institute, Obstetrics and Gynecology Hospital, Fuclan University to do amniocentesis from September 1998 to November 2010, and 13 795 amniotic fluid specimens were successfully extracted and cultured, thus 13 795 fetuses received karyotype diagnosis. These fetuses were grouped according to different indications. If maternal age was ≥ 35, the fetuses were grouped into the advanced maternal age group (4065) ; and if maternal serum screening test revealed high-risk of trisomy 18 or trisomy 21, the fetuses were grouped into the high-risk serum screening group (6462) ; and those with abnormal signs of ultrasound screening were grouped into the abnormal ultrasound signs group (1539); and if either of the parents was with chromosome abnormalities, the fetus was grouped into the paternal/maternal abnormality group ( 108 ) ; whereas the remainder were grouped in other factors group ( 1621 ). The amniotic fluid cells were in-situ cultured on coverslips, harvested by conventional G-banded methods, and then analyzed by two doctors. In order to get rapid diagnosis, some pregnant women whose gestational age ≥26 weeks accepted fluorescense in situ hybridization (FISH). FISH was done on 78 uncultured amniotic fluid specimens using probes located at chromosome 13,18,21, X,Y. Some parents were required to analyze lymphocyte karyotype to help judging the origin of abnormal karyotype. Results( 1 ) Classification and composition of abnormal karyotypes in each group : a total of 388 abnormal karyotypes were found among 13 795 fetuses, and the abnormal rate was 2. 813％ (388/13 795).Of the 388 fetuses, aneuploidy was the most common pattern which was up to 59. 8％(232/388);autosomal structural abnormality rate was 24. 7％ ( 96/388 ) ; mosaicism was 12.4％ (48/388). Other uncommon abnormal karyotypes included marker chromosome (5/388,1.3％), sex chromosomal structural abnormality (4/388,1.0％) and triploid (3/388, 0. 8％ ). Aneuploidy was the most common in most groups except the patemal/matemal abnormality group. There were four cases of rare aneuploid in the advanced maternal age group,the high-risk serum screening group and the abnormal ultrasound signs group respectively. Every type of abnormality could be found in the abnormal ultrasound signs group, and autosomal structural abnormalities were concentratedin paternal/maternalabnormality group. Mosaicism mainly distributed in the high-risk serum screening group, accounting for 20. 0％ (29/145) of abnormalities in this group. (2) Abnormal types and the incidence: the most common type was trisomy 21 ( 138/388,35.6％ ),followed by autosomal balanced structural rearrangements( 80/388, 20. 6％ ), mosaicism(48/388,12. 4％ )and trisomy 18 (44/388,11.3％ ). Others included non-balanced autosomal structural rearrangements (16/388,4. 1％ ), 45 ,X0 ( 16/388,4. 1％ ) and 47 ,XXY( 15/388,3.9％ ). (3) Lymphocyte karyotype analysis of the couples: parents of 153 fetuses were analyzed to determine the origin of abnormal karyotype. Fifty-eight familial and 95 de novo abnormalities were found. FISH results were the same with G-banding karyotype, and two of these were trisomy 21. Conclusions Abnormal karyotype composition is different according to different maternal amniocentisis indications. There is a variety of abnormal karyotypes in the second trimester pregnancy, and the risk of fetal malformation is related with the kind of abnormal karyotype.

Objective To investigate the effect of PCI/CABG for the patients with coronary artery disease(CAD) with LVEF≤40%. Methods 196 CAD patients with LVEF≤40% were divided into PCI (n = 106) and CABG group (n=90). The clinical factors, revaseularization, medication, and in-hospital and follow-up malignant cardiological events(MACCE) were retrospectively compared,and the survival curve were drew by COX regression.Results Survival rate of the PCI group and CABG group in 30-day (96% vs. 94% ), 1-year(95 % vs. 92% ), and 2-year(93% vs. 87% )were similar. There was no MACCE within 30 days in the two groups(92% vs. 92% ) and 1-year survival rate without MACCE was similar in the two groups(86% vs. 88% ). CABG group had higher 2- year survival rate without MACCE than PCI group (83%vs. 72% ). But the COX survival curves of the two group were not signifi-cantly different (P=0. 662). Conclusion The patients with LVEF ≤ 40% undergoing PCI have short-term and long-term survival rate similar to those accepting CABG.

Objective To evaluate the short-term and long-term outcomes of patients with ST-segment elevation myocardial infarction (STEMI) compared with those with non-STEMI after percutaneous coronary intervention (PCI). Method The DESIRE Ⅱ (Drug-Eluting Stent Impact on Revascularization Ⅱ) was a single-center registered retrospective study of coronary revascularization in our institution between July 2003 and September 2009.Data of demographics, clinical features and revascularization record of STEMI and non-STEMI patients from the DESIRE Ⅱ trial were analyzed. The patients were followed up in OPD or by telephone after discharge. MACCE (major adverse cardiocerebral events) including death, neo-myocardial infarction, stroke and revascularization were recorded. The clinical outcomes of patients of two types were evaluated. Results There were 6005 patients studied with a median follow-up of 566 days. A total of 1009 STEMI and non-STEMI patients were analyzed. The patients with non-STEMI ( n = 206) had higher prevalence of hypertension and history of higher frequency of myocardial infarction as well as revascularization compared with patients with STEMI ( n = 803). The patients with non-STEMI had higher ratio of treatment for multivessel disease (43.7% vs. 34.4%, P = 0.039). There were no significant differences in in-hospital mortality and long-term outcomes (one year survival rate: 96% vs. 98%)between patients with STEMI and non-STEMI. The predictors of 1-year mortality were LVEF and blood creatine.Conclusions Despite different chnical features, patients with STEMI and non-STEMI after PCI had similar both short-term and long-term outcomes.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.

Objective To elucidate the clinical characteristics and coronary angiographic findings of patients underwent PCI before and after drug-eluting stents(DES).Methods DESIRE(Drug-Eluting Stent Impact on revascularization) was a retrospective registry of patients who received revascularization therapy during July,2001 through June,2002(non-DES era) and July,2003 through February,2004(DES era).In this analysis,we used the DISIRE data to examine the clinical and angiographic features of patients who received PCI in the different era.Results Among 3763 patients in the registry,2180 patients were analyzed(763 were in the non-DES era and 1417 were in the DES era).In the DES era,more diseased vessels(1.31?0.54 vs 1.39?0.61,P

24 hours) PCI. Results Among 1013 patients enrolled in the SUNDAY registry, 438 (male 74.8%, unstable angina 94.1%) received PCI after CAG, 35 patients received PCI within 24 hours [(1.0?0.0) day, group I], and 403 after 24 hours [ (7.5 ? 7.3) days, group II] of hospitalization (P

Objective To elucidate the clinical characteristics and prognosis of non-ST segment elevation acute coronary syndrome (NSTE-ACS)patients with metabolic syndrome. Methods SUNDAY(The Strategies for UA/NSTEMI and Delay of AngioplastY Registry)study was a retrospective registry of 1 013 patients with unstable angina or NSTEMI from Jan 2000 through Dec 2002. In this analysis , we compared the clinical features and prognosis with patients with or without metabolic syndrome and studied the relation between the number of markers-the MS score and prognosis. Results There were 743 patients with complete data and 343 patients(46.2%)satisfied the definition of Chinese metabolic syndrome .The latter were younger [(59.66?9.67)age vs. (61.11?10.37)age,P=0.052], with higher BMI ,SBP, DBP, blood glucose and disordered blood-lipid(P0.05) and coronary angiographic alterations(left main artery and trivessel) (P=0.006). Conclusion There were prevenlence in NSTE-ACS patients with metabolize syndrome and the later were younger .As the MS score increased so did obesity, dyslipidemia ,blood pressure, fasting glucose. Similarly, an increasing MS score was significantly related to more severe coronary angiographic alterations and cardiac events.
