BACKGROUND Coronary heart disease(CHD)is a type of coronary atherosclerotic heart *** recent years,the incidence of CHD has been increasing annually,with an increasing number of young *** CHD may cause severe myocardial ischemia or myocardial necrosis,which in turn may cause myocardial infarction and related complications that seriously affect the life and health of the *** To examine the coronary arteries and clinical features of young and middle-aged male patients with *** From February 2019 to January 2020,110 male CHD patients admitted to our hospital were selected as research subjects and were divided into two groups by age:middle-aged group(n=55)and young group(n=55).The coronary arteries and clinical features of the patients were *** There were no significant differences in dyslipidemia,stroke history,high-density lipoprotein cholesterol,or triacylglycerol(P>0.05)between the two *** the young group,age,diabetes,hypertension,smoking history,body mass index,family history of CHD,drinking history,fibrinogen,low-density lipoprotein cholesterol,total cholesterol,and single-vessel disease were higher than those in the middle-aged ***,serum uric acid,hyperuricemia,myocardial infarction,Gensini score>50,collateral circulation,multivessel disease,double vessel disease,involvement of the right coronary artery,and involvement of the left main coronary artery were lower in the young group than in the middle-aged *** middle-aged group mainly suffered from a high Gensini score,implicating multiple arteries,whereas the young group was mainly affected by single-vessel *** between-group difference was significant(P<0.05).CONCLUSION In CHD attacks,multiple coronary arteries are implicated in middle-aged male patients and single-vessel disease in young male patients.

Forest data acquisition,which is of crucial importance for modeling global biogeochemical cycles and climate,makes a contribution to building the ecological Digital Earth(DE).Due to the complex calculations and large volumes of data associated with high-resolution images of large areas,accurate and effective extraction of individual tree crowns remains *** this study,two GeoEye-1 panchromatic images of Beihai and Ningbo in China with areas of 5 and 25 km2,respectively,were used as experimental data to establish a novel method for the automatic extraction of individual tree crowns based on a self-adaptive mutual information(SMI)algorithm and tile computing technology(SMI-TCT).To evaluate the performance of the algorithm,four commonly used algorithms were also applied to extract the individual tree *** overall accuracy of the proposed method for the two experimental areas was superior to that of the four other algorithms,with maximum extraction accuracies of 85.7%and 63.8%.Moreover,the results also indicated that the novel method was suitable for individual tree crowns extraction in sizeable areas because of the multithread parallel computing technology.

The small-world network, proposed by Watts and Strogatz, has been extensively studied for the past over ten years. In this paper, a generalized smMl-world network is proposed, which extends severM small-world network models. Furthermore, some properties of a special type of generalized small-world network with given expectation of edge numbers have been investigated, such as the degree distribution and the isoperimetric number. These results are used to present a lower and an upper bounds for the clustering coefficient and the diameter of the given edge number expectation generalized small-world network, respectively. In other words, we prove mathematically that the given edge number expectation generalized small-world network possesses large clustering coefficient and small diameter.
