We report the results of carrier screening of 39,458 East Asian adult women and prenatal diagnosis from 87 FXS carriers.The prevalence of FXS carriers and full mutation fetuses was estimated to be 1/581 and 1/3124 in East Asian populations, respectively. We confirmed the validity of the current threshold of CGG trinucleotide repeats for FMR1 categorization;the integral risks of full mutation expansion were approximately 6.0%,43.8%, and 100% for premutation alleles with 55—74, 75—89, and ≥ 90 CGG repeats, respectively. The protective effect of AGG(adenine-guanine-guanine nucleotides) interruption in East Asian populations was validated, which is important in protecting premutation alleles with 75—89 CGG repeats from full mutation expansion. Finally, family history was shown not an effective indicator for FXS carrier screening in East Asian populations, and population-based screening was more cost-effective. This study provides an insight into the largest carrier screening and prenatal diagnosis for FXS in East Asian populations to date. The FXSassociated genetic profiles of East Asian populations are delineated, and population-based carrier screening is shown to be promising for FXS intervention.展开更多

Despite a higher myopia prevalence in Asia, previous large-scale genome-wide association studies(GWASs) were mostly based on European descendants. Here, we report a GWAS of spherical equivalent(SE) in 1852 Chinese Han individuals with extreme SE from Guangzhou(631 <-6.00 D and 574 > 0.00 D) and Wenzhou(593 <-6.00 D and54 >-1.75 D), followed by a replication study in two independent cohorts with totaling 3538 East Asian individuals. The discovery GWAS and meta-analysis identify three novel loci, which show genome-wide significant associations with SE, including 1 q25.2 FAM163 A, 10 p11.22 NRP1/PRAD3, and 10 p11.21 ANKRD30 A/MTRNR2 L7, together explaining 3.34% of SE variance. 10 p11.21 is successfully replicated.The allele frequencies of all three loci show significant differences between major continental groups(P < 0.001). The SE reducing(more myopic) allele of rs10913877(1 q25.2 FAM163 A) demonstrates the highest frequency in East Asians and much lower frequencies in Europeans and Africans(EAS = 0.60,EUR = 0.20, and AFR = 0.18). The gene-based analysis additionally identifies three novel genes associated with SE, including EI24, LHX5, and ARPP19. These results provide new insights into myopia pathogenesis and indicate the role of genetic heterogeneity in myopia epidemiology among different ethnicities.展开更多

Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up.展开更多

Recurrent chromosomal aberrations in acute leukemia have provided insights into the molecular mechanism of leukemogenesis. The variable frequencies of recurrent cytogenetic markers due to ethical/racial differences have been reported from Western and some Asian countries. Objective: We report cytogenetic data of largest cohort of 7209 adult and pediatric patients with de novo acute leukemia (AL) to determine the prevalence of various cytogenetic sub groups and compare with the Western and Asian population. Material & Methods: The AL patients included 2609 AML (adult: 2042, pediatric: 567), 3708 B-cell-precursor (BCP)-ALL (adult: 1300, pediatric: 2408) and 892 cases of T-ALL (adult: 480, pediatric: 412). Cytogenetic studies included conventional karyotyping and FISH using panel of probes. Results: The incidence of t(8;21) was high, comparable to other Asian countries. In comparison to our series and Western population, t(15;17) was more prevalent in Chinese population. Cytogenetic profiling of BCP-ALL revealed low prevalence of ETV6/RUNX1 in ours as well as other Asian population. The MLL aberrations in BCP-ALL and TLX1 & TLX3 aberrations in T-ALL occurred less frequently in our series as compared with Western population. Conclusion: The present study with a large cohort showed the heterogeneity of AL that involved various factors, such as age, gender and prevalence of distinct cytogenetic subgroups. Our data in comparison with other population based studies revealed differential distribution of some cytogenetic sub-groups indicating geographic heterogeneity due to differential environmental exposure which probably influenced underlying genetic susceptibility.展开更多

To maintain a very satisfactory radio-opacity using the stents, Guidant of the USA has designed a new type of bare metal stents (BMS)-Multi-link (ML) Vision / ML MiniVision stents. The clinical outcomes of Asian patients with coronary artery disease (CAD) after implanting the Multi-link Vision or MiniVision stent were investigated in this study. Methods An observational, prospective, multi-center, non-randomized post marketing registry was conducted to demonstrate the efficacy of the BMS- ML Vision / ML MiniVision stents. The primary end point of the registry was clinical target lesion revascularization (TLR) at a 6-month follow-up. The major secondary end points included the rate of major adverse cardiac events (MACE) and serious adverse events (SAE) in hospital and at 6 months; and the rate of clinical TLR as a function of the type of angina. A total of 429 Asian people with 449 lesions from 14 centers were selected for this study, The average reference diameter of the lesions was (3.0±0.5) mm, and the mean length was (15.7±5.0) mm. Results The successful rate of the procedure was 99.3%. Twenty-five percent of the lesions were treated by direct stenting without pre-dilation. Eighty-six percent of the lesions were implanted with ML Vision stent. After the 6-month follow-up, the rate of clinical TLR was 1.4%. The MACE, SAE and target vessel revascularization (TVR) were 6.8%, 3.5% and 1.4% respectively. Conclusion The current registry showed the excellent 6-month clinical outcomes of ML Vision/ML MiniVision stents in Asian patients with CAD.展开更多

文摘Background There are numerous but conflicting data regarding gender differences in outcomes following percutaneous coronary intervention(PCI). Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up.
文摘Background: Cytogenetics is one of the most important diagnostic parameters in the classification of acute leukemia. Recurrent chromosomal aberrations in acute leukemia have provided insights into the molecular mechanism of leukemogenesis. The variable frequencies of recurrent cytogenetic markers due to ethical/racial differences have been reported from Western and some Asian countries. Objective: We report cytogenetic data of largest cohort of 7209 adult and pediatric patients with de novo acute leukemia (AL) to determine the prevalence of various cytogenetic sub groups and compare with the Western and Asian population. Material & Methods: The AL patients included 2609 AML (adult: 2042, pediatric: 567), 3708 B-cell-precursor (BCP)-ALL (adult: 1300, pediatric: 2408) and 892 cases of T-ALL (adult: 480, pediatric: 412). Cytogenetic studies included conventional karyotyping and FISH using panel of probes. Results: The incidence of t(8;21) was high, comparable to other Asian countries. In comparison to our series and Western population, t(15;17) was more prevalent in Chinese population. Cytogenetic profiling of BCP-ALL revealed low prevalence of ETV6/RUNX1 in ours as well as other Asian population. The MLL aberrations in BCP-ALL and TLX1 & TLX3 aberrations in T-ALL occurred less frequently in our series as compared with Western population. Conclusion: The present study with a large cohort showed the heterogeneity of AL that involved various factors, such as age, gender and prevalence of distinct cytogenetic subgroups. Our data in comparison with other population based studies revealed differential distribution of some cytogenetic sub-groups indicating geographic heterogeneity due to differential environmental exposure which probably influenced underlying genetic susceptibility.
文摘Background Recent studies have showed that the fine mesh stents are associated with a significant reduction in both clinical and angiographic re-stenosis of the coronary arteries. To maintain a very satisfactory radio-opacity using the stents, Guidant of the USA has designed a new type of bare metal stents (BMS)-Multi-link (ML) Vision / ML MiniVision stents. The clinical outcomes of Asian patients with coronary artery disease (CAD) after implanting the Multi-link Vision or MiniVision stent were investigated in this study. Methods An observational, prospective, multi-center, non-randomized post marketing registry was conducted to demonstrate the efficacy of the BMS- ML Vision / ML MiniVision stents. The primary end point of the registry was clinical target lesion revascularization (TLR) at a 6-month follow-up. The major secondary end points included the rate of major adverse cardiac events (MACE) and serious adverse events (SAE) in hospital and at 6 months; and the rate of clinical TLR as a function of the type of angina. A total of 429 Asian people with 449 lesions from 14 centers were selected for this study, The average reference diameter of the lesions was (3.0±0.5) mm, and the mean length was (15.7±5.0) mm. Results The successful rate of the procedure was 99.3%. Twenty-five percent of the lesions were treated by direct stenting without pre-dilation. Eighty-six percent of the lesions were implanted with ML Vision stent. After the 6-month follow-up, the rate of clinical TLR was 1.4%. The MACE, SAE and target vessel revascularization (TVR) were 6.8%, 3.5% and 1.4% respectively. Conclusion The current registry showed the excellent 6-month clinical outcomes of ML Vision/ML MiniVision stents in Asian patients with CAD.
文摘Preeclampsia(PE)is one of the leading causes of maternal and perinatal morbidity and mortality worldwide.This disorder has profound short-term and long-term impacts on both the affected woman’s and her child’s health.Early-onset PE requiring preterm delivery(preterm PE)is of particular importance because it is associated with a higher risk of adverse pregnancy outcomes than term PE.First trimester screening model developed by the Fetal Medicine Foundation(FMF),which uses Bayes-theorem to combine maternal characteristics and medical history together with measurements of mean arterial pressure,uterine artery pulsatility index,and serum placental growth factor,has been proven to be effective and have superior screening performance to that of traditional risk factor-based approach for the prediction of PE.Identification of high risk pregnant women for preterm PE and giving aspirin prophylaxis before 16^(th)week of gestation would reduce the incidence of preterm PE.In Asia,although the prevalence of PE is slightly lower than the global estimation,early screening and prevention of this life-threatening condition is still crucial.The FMF Bayestheorem based screening method has been validated in a large-scale prospective Asia-wide study and revealed that the first trimester triple test achieves the highest detection rate,compared with the traditional risk factor-based approaches,and that the screening performance is comparable to the published data from the FMF in East Asian women.However,in order to achieve optimal screening performance,the key is to establish standardized methods for biomarker measurements and regular biomarker quality assessment,as each biomarker is susceptible to inaccurate measurement,thus affecting performance of screening.Furthermore,it is of great importance to emphasize that the optimal preventive effect of aspirin on preterm PE is clearly associated with good compliance to treatment.In conclusion,global implementation of an effective first trimester“screen and prevent”program for preterm PE would provide the opportunity to reduce the risk of both short-term maternal and perinatal morbidity and mortality,with the possibility of intergenerational prevention of future chronic diseases for both the mother and her offspring.

文摘While disrupted lipid metabolism is a well-established risk factor for hypertension in animal models,the links between various lipidomic signatures and hypertension in human studies remain unclear.We aimed to examine associations between plasma lipidomic profiles and prevalence of hypertension among 2248 community-living Chinese aged 50-70 years.Hypertension was defined according to 2020 International Society of Hypertension global hypertension practice guidelines and 2018 Chinese guidelines.In total,728 plasma lipidomic species were profiled using high-coverage targeted lipidomics.After multivariate adjustment,including lifestyle,body mass index,blood lipids,and sodium intake,110 metabolites from nine lipidomic subclasses showed significant associations with hypertension,among which phosphatidylethanolamines(PEs)had the strongest association.Eleven lipidomic signals for hypertension risk were further identified from the nine subclasses,including PE(18:0/18:2)(OR per SD,1.49;95%confidence intervals,1.30-1.69),phosphatidylcholine(PC)(18:0/18:2)(1.27;1.13-1.43),phosphatidylserine(18:0/18:0)(1.24;1.09-1.41),lysophosphatidylinositol(18:1)(1.17;1.06-1.29),triacylglycerol(52:5)(1.38;1.18-1.61),diacylglycerol(16:0/18:2)(1.42;1.19-1.69),dihydroceramide(24:0)(1.25;1.09-1.43),hydroxyl-sphingomyelins(SM[2OH])C34:1(1.19;1.07-1.33),lysophosphatidylcholine(20:1)(0.86;0.78-0.95),SM(OH)C38:1(0.87;0.79-0.96),and PC(18:2/20:1)(0.84;0.75-0.94).Principal component analysis also showed that a factor mainly containing specific PEs was positively associated with hypertension(1.20;1.09-1.33).Collectively,our study revealed that disturbances in multiple circulating lipidomic subclasses and signatures,especially PEs,were significantly associated with the prevalence of hypertension in middle-aged and elderly Chinese.Future studies are warranted to confirm our findings and determine the mechanisms underlying these associations.
