Objectives:To investigate the impacts of American College of Cardiology/American Heart Association (ACC/AHA) coronary artery classification on the progression of coronary non-target lesions and revascularization in patients with coronary heart disease.Methods:From January 2010 to September 2014,1255 patients who underwent two consecutive coronary angiographies at Fuwai Hospital and had coronary non-target lesions were retrospectively analyzed.Lesion characteristics of all coronary non-target lesions were recorded at both procedures.All non-target lesions were divided into A,B1,B2 and C lesion group according to ACC/AHA coronary artery classification.Patients were divided into non-B2/C lesion group (noncomplex lesion group) and B2/C lesion group (complex lesion group) according to whether the non-target lesion had B2/C lesion The characteristics of all non-target coronary artery lesions and quantitative coronary angiography results were recorded.Lesion progression and revascularization were compared between different groups.Results:There were 1003 (79.9％) male patients,mean age was (58.0±9.7) years old,and 853 patients had B2/C lesions.There were 1670 non-target lesions,including 619 A/B1 lesions (214 A lesions and 405 B1 lesions) and 1051 B2/C lesions (796 B2 lesions and 255 C lesions).Follow-up time was (14.8±4.5) months.Compared with the patients in noncomplex lesion group,patients in complex lesion group were older,had lower proportion of family history of coronary heart disease and stroke (all P<0.05).The baseline levels of leukocytes,C-reactive protein,erythrocyte sedimentation rate (ESR),triglyceride and HbA1c were higher in complex lesion group than those in noncomplex lesion group.Complex lesion group had higher risk of lesion progression (21.8％ vs.13.2％,P<0.001) compared with noncomplex lesion group,similar results were observed in revascularization (16.5％ vs.11.2％,P=0.013),and there was no statistically difference in non-target lesion related myocardial infarction (P>0.05).At the lesion level,compared with A/B1 lesion,B2/C lesion was associated with a higher rate of lesion progression (17.4％ vs.11.0％,P<0.001),and a higher rate of revascularization (13.0％ vs.9.2％,P=0.018).Multivariate Cox regression analysis showed that lesion classification (B2/C) was an independent risk factor for non-target lesion progression (HR=1.732,95％CI:1.275-2.351,P<0.001) and non-target lesion revascularization (HR=1.477,95％CI:1.053-2.070,P=0.024).Conclusions:The risk of non-target lesion progression and revascularization is higher in complex groups compared with noncomplex groups according to ACC/AHA classification.So patients with complex lesions should receive more strict medical care to control related risk factors and improve their outcome.

Pelagic cephalopods have evolved a series of fascinating traits,such as excellent visual acuity,high-speed agility,and photophores for adaptation to open pelagic oceans.However,the genetic mechanisms underpinning these traits are not well understood.Thus,in this study,we obtained high-quality genomes of two purpleback flying squid species(Sthenoteuthis oualaniensis and Sthenoteuthis sp.),with sizes of 5450 Mb and 5651 Mb,respectively.Comparative genomic analyses revealed that the S-crystallin subfamily SL20-1 associated with visual acuity in the purple-back flying squid lineage was significantly expanded,and the evolution of high-speed agility for the species was accompanied by significant positive selection pressure on genes related to energy meta-bolism.These molecular signals might have contributed to the evolution of their adaptative preda-tory and anti-predatory traits.In addition,the transcriptomic analysis provided clear indications of the evolution of the photophores of purpleback flying squids,especially the recruitment of new genes and energy metabolism-related genes which may have played key functional roles in the pro-cess.
