In general, low density lipoprotein (LDL), particularly oxidized-LDL, plays an important role in the occurrence and development of lipid-rich atheromatous plaque,~1 and the consequence is basis for plaque instability, rupture, and further complications.~ 2,3 And a high LDL-triglyceride level was related to progression of coronary atherosclerosis,~4 and the increments of serum triglyceride (TG) and LDL-triglyceride were risk factors for coronary artery disease.~ 5,6 Therefore, lipid-modifying therapy may have a beneficial effect on the prevention and treatment of atherosclerosis and its complications.~ 7,8 Because it is difficult to isolate and purify LDL, there are few data on total cholesterol (TC) and TG in LDL and consequently there is little information on the relationship between the lipid profile and levels of TC and TG in LDL. Xiaoyu tablet, a compound prepared from Chinese herbal medicines, consists of Radix Salviae Miltiorrhizae and Fructus Crataegi extracts. Our previous studies have demonstrated that the drug possesses the regulation of blood lipid and regression of atherosclerosis.~ 9-12 In this study, we observed the effects of Xiaoyu tablet on blood lipid, lipoproteins, and levels of TC and TG in LDL in atherosclerotic hyperlipidemic rabbits, and analysed their correlation and clinical significance.

An innovative multi-layer composite explosion containment vessel(CECV)utilizing a sliding steel platealuminum honeycomb-fiber cloth sandwich is put forward to improve the anti-explosion capacity of a conventional single-layer explosion containment vessel(SECV).Firstly,a series of experiments and finite element(FE)simulations of internal explosions are implemented to understand the basic anti-explosion characteristics of a SECV and the rationality of the computational models and methods is verified by the comparison between the experimental results and simulation *** on this,the CECV is designed in detail and a variety of FE simulations are carried out to investigate effects of the sandwich structure,the explosive quantity and the laying mode of the fiber cloth on anti-explosion performance and dynamic response of the CECV under internal *** results indicate that the end cover is the critical position for both the SECV and *** maximum pressure of the explosion shock wave and the maximum strain of the CECV can be extremely declined compared to those of the *** a result,the explosive quantity the CECV can sustain is up to 20 times of that the SECV can ***,as the explosive quantity increases,the internal pressure of the CECV keeps growing and the plastic deformation and failure of the sandwich structure become more and more severe,yielding plastic strain of the CECV in addition to elastic *** results also reveal that the laying angles of the fiber cloth's five layers have an impact on the anti-explosion performance of the *** example,the CECV with fiber cloth layered in 0°/45°/90°/45°/0°mode has the optimal anti-capacity,compared to 0°/0°/0°/0°/0°and 0°/30°/60°/30°/0°***,owing to remarkable anti-explosion capacity,this CECV can be regarded as a promising candidate for explosion resistance.
