Multip.e stellar.p.p.lations(Mp.) in most star.clusters older than 2 Gyr. as seen by lots of sp.ctr.scop.c and p.otometr.c studies, have led to a significant challenge to the tr.ditional view of star.for.ation. In this field, sp.cebased instr.ments, in p.r.icular.the Hubble Sp.ce Telescop.(HST), have made a br.akthr.ugh as they significantly imp.oved the efficiency of detecting Mp. in cr.wded stellar.fields by images. The china Sp.ce Station Telescop.(CSST) and the HST ar. sensitive to a similar.wavelength interval, but the CSST covers a field of view which is about 5–8 times wider than that of HST. One of its instr.ments, the Multi-Channel Imager(MCI),will have multip.e filters covering a wide wavelength r.nge fr.m NUV to NIr. making the CSST a p.tentially p.werful tool for.studying Mp. in clusters. In this wor., we evaluate the efficiency of the designed filters for.the MCI/CSST in r.vealing Mp. in different color–magnitude diagr.ms(CMDs). We find that CMDs made with MCI/CSST p.otometr. in ap.r.p.iate UV filters ar. p.werful tools to disentangle stellar.p.p.lations with different abundances of He, C, N, O and Mg. On the contr.r., the tr.ditional CMDs ar. blind to multip.e p.p.lations in globular.clusters(GCs). We show that CSST has the p.tential of being the sp.ar.ead instr.ment for.investigating Mp. in GCs in the next decades.

目的探讨平均血小板体积(mean p.atelet volume,Mp.)联合尿酸浓度能否预测急性心肌梗死患者支架术后的心功能。方法随机选择2017年6月至2019年1月于中山大学附属江门医院拟诊ST段抬高型心肌梗死(ST-segment elevation myocar.ial infar.tion,STEMI)、急性非ST段抬高型心肌梗死(non ST-segment elevation myocar.ial infar.tion,NSTEMI)和健康体检者各55名为STEMI组、NSTEMI组和对照组。检测3组患者的Mp.及尿酸浓度。起病后1周和40 d,对急性心肌梗死患者进行心功能评定,并记录这两个时间段超声心动图的左心室舒张末期内径(left ventr.cular.end-diastolic dimension,LVEDD)和左心室射血分数(left ventr.cular.ejection fr.ction,LVEF)。结果与对照组比较,NSTEMI组和STEMI组的Mp.、尿酸浓度较高,差异有统计学意义(p.0.05)。起病1周时心功能(Killip.级)≥2级急性心肌梗死患者的Mp.、尿酸浓度、LVEDD较心功能(Killip.级)1级患者升高,差异有统计学意义(p.0.05)。起病40 d时纽约心脏协会(New Yor. Hear. Association,NYHA)心功能分级≥2级急性心肌梗死患者Mp.、尿酸浓度、LVEDD较心功能NYHA分级1级患者升高,差异有统计学意义(p.0.01)。回归分析结果显示,起病1周时心功能Killip.2级急性心肌梗死患者Mp.、尿酸浓度的β值分别为0.573(p.0.05)和2.073(p.0.01);起病40 d时心功能NYHA分级≥2级急性心肌梗死患者的Mp.、尿酸浓度的β值分别为0.516(p.0.01)和0.397(p.0.05)。高水平的Mp.和高尿酸浓度都是急性心肌梗死患者起病1周、40 d时发生心功能不全的危险因素;Mp.、尿酸浓度共同预测急性心肌梗死患者1周、40 d发生心功能不全的r.2分别为0.543(p.0.05)和0.756(p.0.01)。结论联合检测Mp.、尿酸浓度能准确预测支架术后急性心肌梗死患者起病1周、40 d的心功能。
