OBJECTIVE: To evaluate the relationship between autoantibodies against oxidized low density lipoprotein(ox- LDL), immune complex and coronary artery disease(CAD). METHODS: The levels of autoantibodies against ox-LDL and immune complex were assayed by ELISA, the content of ox-LDL and lipid levels were also measured. The serum samples were taken from 61 patients with CAD, 116 patients with essential hypertension(EH) and 123 healthy individuals as control. RESULTS: The patients with CAD had significantly higher levels of anti-ox-LDL IgG[21.48(17.58 approximate, equals 29.01)U/L], anti-ox-LDL IgM4.71[3.88 approximate, equals 7.06)U/L] and ox-LDL[0.87(0.44 approximate, equals 1.08) mg/L] than EH group[15.93(11.12 approximate, equals 22.26) U/L 2.54(1.17 approximate, equals 5.05) U/L 0.32(0.16 approximate, equals 0.61) mg/L]and healthy control group[11.12(4.70 approximate, equals 16.57)U/L 1.61(0.60 approximate, equals 3.03)U/L 0.23(0.12 approximate, equals 0.36)mg/L], P<0.001. However, the serum ox-LDL immune complex[2.63(1.69 approximate, equals 5.90)U/L] was significantly lower in CAD than that in EH group[15.71(6.25 approximate, equals 28.74)U/L] and that in healthy control group[12.54(8.28 approximate, equals 23.90)U/L], P<0.001. There were discrepancies in the association between ox-LDL and autoantibodies against ox-LDL among different groups. CONCLUSION: The changes of autoantibodies against ox-LDL and immune complex in patients with CAD may be related to the role of ox-LDL and autoantibodies against ox-LDL in the process of coronary atherosclerosis.

OBJECTIVE: To investigate the clinical significance of plasma homocysteine Hcy in patients with coronary atherosclerosis. METHODS Plasma Hcy levels of 85 patients with coronary atherosclerosis and 68 normal controls were determined by fluorescence polarization immunoassay. RESULTS The mean levels of plasma Hcy were (9.31+/-3.80)&mgr;mol/L in normal controls and (13.39+/-6.06)&mgr;mol/L in patients with coronary atherosclerosis. That was (11.36+/-3.86)&mgr;mol/L in the patients with micro-pathological changes of coronary artery, (13.32+/-6.09)&mgr;mol/L with single-vessel disease,(13.39+/-4.92)&mgr;mol/L with double-vessel disease, and (18.23+/-8.98)&mgr;mol/L with three-vessel disease by coronary angiography. Statistically, the mean plasma Hcy concentrations in male and female patients was higher than that in the corresponding control subjects(13.77+/-6.68 compared with 10.50+/-4.07, 11.50+/-3.58 compared with 7.80+/-2.85 &mgr;mol/L,P<0.001 respectively). CONCLUSION The patients with coronary atherosclerosis present hyperhomocysteinemia is very important to determine plasma homocysteine for diagnosis and therapy in the patients with coronary heart disease.

Under normal physiology, insulin exerts vasodilatory and pro-survival actions via the phosphatidylinositol 3-kinase (PI3-kinase) pathway and vasoconstrictive and mitogenic actions via the mitogen-activated protein kinase (MAPK) pathway in the vasculature. In the insulin resistant states, insulin signals through the PI3-kinase pathway are blunted but its signals through the MAPK cascade remain intact. This imbalance predisposes insulin resistant patients to hypertension and atherosclerosis. The renin-angiotensin system (RAS) is expressed both systemically and locally in the cardiovascular system. Insulin resistance up-regulates the local RAS which contributes to the pathogenesis of hypertension, heart failure, and atherosclerosis. Angiotensin II impairs insulin signaling, induces inflammation via the NF-kappaB pathway, reduces nitric oxide availability and facilitates vasoconstriction, leading to insulin resistance and endothelial dysfunction. Thus the RAS, insulin resistance and inflammation perpetuate each other and coordinately contribute to endothelial dysfunction, vascular injury and atherosclerosis. RAS inhibition decreases cardiovascular and renal morbidity and mortality and the incidence of new onset Type 2 diabetes.

CD40/CD40L is a pair of complementary transmembrane glycoproteins, expressed on immune cells, endothelial cells, smooth muscle cells, platelets and other cells involved in regulation of immunity, inflammation, coagulation and other pathophysiologic states. A large number of researches have demonstrated that, when atherosclerosis occurs, CD40L ligates CD40; subsequently CD40 is activated and stimulates downstream signaling pathways, including nuclear factor-kappaB, with consequent up-regulation of proinflammatory and proatherogenic genes. Thus it plays an important role in the occurrence, development and plaque-rupture of atherosclerosis. CD40/CD40L is a bridge between immunity, inflammation, and a hypercoagulable state, and may be an important target for prevention and treatment of cardiovascular disease.

Off-pump coronary-coronary bypass grafting (CABG) is a main treatment for coronary artery disease and CCBG is one kind of CABG. CCBG is defined as bypass between two segments of the same coronary artery or between different coronary arteries. We present here a case of CCBG using the off-pump technique. The patient had extensive aortic atherosclerosis and both saphenous veins were varicose and therefore only short portions were usable. For some special patients, it is possible to achieve better long-term results and quality of life by CCBG. For surgical approaches, strategy must come before tactics.

Hyperlipidemia is one of the most important risk factors for atherosclerosis, coronary heart disease and other cardiovascular diseases. It is the main effect of lipid-lowering drugs to reduce the plasma low-density lipoprotein or to enhance high-density lipoprotein. Niemann-Pick C1 like 1 protein (NPC1L1), acyl-coenzyme A: cholesterol acyltransferases (ACAT), ATP binding cassette transporter G member 5 and member 8 (ABCG5/G8), microsomal triglyceride transfer protein (MTP), monoacylglycerol acyltransferase, diacylglycerol acyltransferases (MAGT), peroxisome proliferator-activated receptor (PPAR), farnesoid X receptor (FXR), and proprotein convertase subtilisin/kexin type 9 (PCSK9) play key roles in the metabolism of lipid, which are regarded as the targets of anti-hyperlipidemia drugs and evidence for clinic choice of lipid-lowering drugs. These proteins are considered as breakthrough points for new lipid-lowering drug development.

Endothelial progenitor cells (EPCs) are a kind of progenitor cells with high potential of proliferation, which exist in the bone marrow, umbilical cord blood, and peripheral blood. Under certain conditions, EPCs can differentiate into mature vascular endothelial cells. Many studies have shown that EPCs could delay the onset and development of atherosclerosis by promoting the repair of the endothelium and neovascularization. EPCs have also been considered to be a biological marker for cardiovascular diseases. Recent investigations demonstrate that EPCs can mediate the effect of some anti-atherosclerosis drugs. This paper reviews the role of EPCs in atherosclerosis and the influence of drugs on EPC function. The feasibility and the problem of using EPCs as a treatment strategy are also discussed.

Nicotinamide phosphoribosyltransferase (Nampt) is also called visfatin or pre-B-cell colony-enhancing factor. The functions of Nampt have been reported as a cytokine, an adipokine and the rate-limiting enzyme in nicotinamide adenine dinucleotide biosynthesis. As a pleiotropic multifunctional protein, Nampt is involved in a variety of physiological and pathological conditions including innate immunity, metabolic disorders, and stress; and Nampt also participates in inflammatory disorders such as acute lung injury, atherosclerosis, myocardial infarct, obesity, type 2 diabetes, and rheumatoid arthritis. The studies indicate that Nampt might be a potential target for pharmacological intervention against inflammatory diseases. We review research advances on the roles of Nampt in inflammation.

Endothelial injury or dysfunction leads to multiple cardiovascular diseases, such as atherosclerosis, myocardial infarction, stroke, hypertension and peripheral vascular disease. Endothelial progenitor cells (EPCs) are precursor cells of endothelial cells, including the early endothelial progenitor cells and the late endothelial progenitor cells. These two EPC types have different function and surface markers. EPC in this article mainly means late endothelial progenitors which could grow into endothelial cloning and form vessels in vivo. Late EPCs can express CD133, CD31, KDR, CD144, CD34 etc, take in low density lipoprotein, bind with ulex europaeus lectin 1 and form blood vessels in vitro and in vivo. EPCs not only participate in new blood vessels formation, but also are closely related to the repair of damaged endothelium. Many studies confirm that the transplanted EPCs are able to be mobilized to vascular injury location and repair the damaged endothelial cells thus promote new blood vessel formation, which provides a promising strategy for the treatment of cardiovascular diseases and ischemic diseases.

5-Lipoxygenase, one of lipoxygenase isozymes, is a well-studied oxidative metabolism enzyme. It widely exists in various human tissues and cells, participates in the oxidative metabolism of endogenous and exogenous chemicals, and produces a variety of metabolites, all of which contribute to the occurrence of human diseases, such as inflammation, asthma, atherosclerosis, and tumor and so on. The expression of 5-lipoxygenase is at low level in normal human tissues while at high level in abnormal tissues. 5-Lipoxygenase is closely related to many kinds of diseases in human ovary, brain, cardiovascular system, lung, liver, pancreas and other tissues. The abnormal expression of 5-lipoxygenase tends to promote the development of the disease.
