RESUMO
The concept and principle of 3D printing technology were described,and its advantages were expounded according to the demands of emergency medical equipment.The application of 3D printing technology in the field of emergency medical equipment was analyzed from six aspects,such as equipment system,disposition model,development and innovation,use-pattern,maintenance methods,comprehensive benefit etc,to provide the references to the future construction and development of emergency medical equipment.It's pointed out 3D,4D and 5D printing technologies were of great significance for driving the development of emergency medical equipment.
RESUMO
Objective:To analyze risk factors and prognostic risk factors in aged patients with coronary heart disease (CHD).Methods:Clinical data of 412 aged patients,who were suspected of CHD in our hospital,were retrospec-tively analyzed.According to results of coronary angiography,they were divided into CHD group (n=283 )and non-CHD group (n=129);risk factors and prognostic risk factors for aged CHD patients were analyzed.Results:Compared with non-CHD group,there were significant rise in percentages of >80 years (13.95% vs.28.98%),di-abetes mellitus (DM,37.98% vs.66.78%)and smoking history (32.56% vs.59.72%)in CHD group,levels of to-tal cholesterol [TC,(5.06±1.53)mmol/L vs.(5.41±1.36)mmol/L],triglyceride [TG,(1.53±0.82)mmol/L vs.(2.02±0.95)mmol/L]and low density lipoprotein cholesterol [LDL-C,(2.05±0.86)mmol/L vs.(2.57 ±1.15)mmol/L],and significant reduction in high density lipoprotein cholesterol level [HDL-C, (1.65 ±0.52) mmol/L vs.(0.86±0.38)mmol/L]in CHD group,P <0.05 or <0.01. Multi-factor Logistic regression analysis indicated that age,DM,hypertension history,smoking,high total cholesterol (TC)and hypertriglyceridemia were independent risk factors for CHD (OR= 1.38 ~8.65,P <0.05 or <0.01 );while serum total bilirubin and high density lipoprotein cholesterol were independent protective factors for CHD (OR=0.224,P =0.002);multi-factor Cox model analysis indicated that smoking history,high TC and hypertension were risk factors affecting prognosis of CHD patients (RR= 1.563 ~ 2.315,P < 0.05 all).Conclusion:In clinic,attention should be paid to reduce or eliminaterelated risk factors of aged CHD patients to improve prognosis.
