Atherosclerosis(AS) is caused by impaired lipid metabolism, which deposits lipids in the intima, causes vascular fibrosis and calcification, and then leads to stiffening of the vascular wall. Hyperlipidemia(HLP) is one of the key risk factors for AS. Based on the theory of "nutrients return to the heart and fat accumulates in the channels", it is believed that the excess fat returning to the heart in the vessels is the key pathogenic factor of AS. The accumulation of fat in the vessels over time and the blood stasis are the pathological mechanisms leading to the development of HLP and AS, and "turbid phlegm and fat" and "blood stasis" are the pathological products of the progression of HLP into AS. Didang Decoction(DDD) is a potent prescription effective in activating blood circulation, removing blood stasis, resolving turbidity, lowering lipids, and dredging blood vessels, with the functions of dispelling stasis to promote regeneration, which has certain effects in the treatment of atherosclerotic diseases. This study employed high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(HPLC-Q-TOF-MS/MS) to screen the main blood components of DDD, explored the targets and mechanisms of DDD against AS and HLP with network pharmacology, and verified the network pharmacological results by in vitro experiments. A total of 231 blood components of DDD were obtained, including 157 compounds with a composite score >60. There were 903 predicted targets obtained from SwissTargetPrediction and 279 disease targets from GeneCards, OMIM, and DisGeNET, and 79 potential target genes of DDD against AS and HLP were obtained by intersection. Gene Ontology(GO) analysis suggested that DDD presumably exerted regulation through biological processes such as cholesterol metabolism and inflammatory response, and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis suggested that signaling pathways included lipid and atherosclerosis, insulin resistance, chemo-carcinogenesis-receptor activation, and AGE-RAGE signaling pathways in diabetic complications. In vitro experiments showed that DDD could reduce free fatty acid-induced lipid accumulation and cholesterol ester content in L02 cells and improve cellular activity, which might be related to the up-regulation of the expression of PPARα, LPL, PPARG, VEGFA, CETP, CYP1A1, and CYP3A4, and the down-regulation of the expression of TNF-α and IL-6. DDD may play a role in preventing and treating AS and HLP by improving lipid metabolism and inflammatory response, and inhibiting apoptosis with multi-component, multi-target, and multi-pathway characteristics.

Nutrition labels are helpful for chronic disease management in patients requiring balanced nutritional intake. This study aimed to investigate the association between the use of nutrition labels and chronic diseases (hypertension, diabetes mellitus, and hyperlipidemia) by using the 2008-2009 Korea National Health and Nutrition Examination Survey data. A total of 10,695 individuals aged 20 and over was included in the analysis. Using multiple logistic regressions, there was no difference in nutrition label use between the chronic disease and normal groups (men with hypertension OR, 0.97; 95% CI, 0.75-1.27; women with hypertension OR, 0.83; 95% CI, 0.67-1.03; men with diabetes OR, 0.70; 95% CI, 0.45-1.08; women with diabetes OR, 1.13; 95% CI, 0.84-1.53; men with hyperlipidemia OR, 0.85; 95% CI, 0.59-1.23; women with hyperlipidemia OR, 1.14; 95% CI, 0.91-1.44). In hyperlipidemia patients, awareness (OR, 1.55; 95% CI, 1.03-2.35) and control (OR, 2.19; 95% CI, 2.32-3.63) of disease were related to nutrition label use; however, no significant associations were found for the hypertension and diabetes mellitus patients. Considering the importance of dietary habits in the management of chronic diseases, an improvement in nutrition label use by patients with these diseases is required.

OBJECTIVETo observe the inhibiting effect of acupuncture on blood lipid, myocardial hypertrophy and fibrosis in mice with hyperlipemia, and explore its possible action mechanism.

METHODSTen inbred mice (C57) were applied. Forty ApoE(-/-) mice who removed gene of apolipoprotein E were randomly divided into a control group, a non-acupoint group, an acupoint group and a medication group. The points 0. 5 cm and 1 cm next to the end of mice tail were respectively punctured in the non-acupoint group; "Neiguan" (PC 6) and "Fenglong" (ST 40) were punctured in the acupoint group; intragastric administration of simvastatin was applied in the medication group. After 8 weeks of treatment, the changes of total cholesterol (TC) and ratio of heart to body mass in each group were measured; changes of cardiac muscle fiber and ventricular wall thickness were observed; enzyme linked immunosorbent assay (ELISA) was used to test the level of angiotensin II (Ang I ) in plasma, and western blotting method was used to test protein content of angiotensin II type 1 receptor (AT1R) and endothelin-1 type A receptor (ETAR) in the heart.

RESULTSAfter 8 weeks of intervention, compared with the control group, rising range of blood lipid was obviously decreased (P<0.01) in the acupoint group and medication group, ratio of P<0.01), myocardial heart to body mass was decreased (P<0.05), thickness of ventricular wall was reduced (P fibrosis was relieved, levels of Ang II and ET-1 in plasma were decreased (P<0. 05), content of NO was increased (P<0. 05), and protein content of AT1R and ETAR was decreased in the heart (P<0. 05).

CONCLUSION40) could inhibit the rising of blood lipid in ApoE(-/-) mice, lower the levels of Ang II and ET-1 in peripheral blood, increase the content of NO and inhibit the expression of AT1R and ETAR in heart tissue, which could relieve myocardial hypertrophy and fibrosis to play a protective role on heart.

OBJECTIVETo investigate the effect of Antrodia cinnamomea on gene expression related to aortal endothelial injury of rats with hyperlipidemia.

METHODFifty SD rats were randomly divided into five groups: the normal control group (NG), the model group (MG), the antrodia cinnamomea groups of low, middle and high doses (AC-LG, AC-MG, AC-HG, 250, 500, 1 000 mg x kg(-1)). The rats were fed with high-fat diets to establish the hyperlipidemia model. After the drug administration for 10 weeks, their serum lipid, SOD, MDA and ox-LDL, LOX-1, P38 MAPK and NF-kappaB mRNA and protein expression were respectively determined, and the aortal endothelial injury was observed under electron microscope.

RESULTIn the model group, the contents of TC, TG and LDL-C significant increased (P < 0.01), whereas the content of HDL-C significant decreased (P < 0.01). Compared with the model group, both the AC-M group and the AC-H group showed reduction in endothelial injury and significant decrease in the content of TC, TG and LDL-C (P < 0.05 or P < 0.01). The content of HDL-C increased, but with no significant difference. SOD activity in serum remarkably increased (P < 0.05 or P < 0.01), MDA and ox-LDL levels dramatically decreased (P < 0.05 or P < 0.01).

CONCLUSIONA. cinnamomea can alleviate endothelial lipid injury by inhibiting the expressions of LOX-1, P38MAPK and NF-kappaB in aorta and better protect aortal endothelial cells from oxidative lipid injury.

Over the last two decades, significant research attention has been given to the acute effect of a single bout of exercise on postprandial lipaemia. A large body of evidence supports the notion that an acute bout of aerobic exercise can reduce postprandial triacylglycerol (TAG) concentrations. However, this effect is short-lived emphasising the important role of regular physical activity for lowering TAG concentrations through an active lifestyle. In 1995, the concept of accumulating physical activity was introduced in expert recommendations with the advice that activity can be performed in several short bouts throughout the day with a minimum duration of 10 minutes per activity bout. Although the concept of accumulation has been widely publicised, there is still limited scientific evidence to support it but several studies have investigated the effects of accumulated activity on health-related outcomes to support the recommendations in physical activity guidelines. One area, which is the focus of this review, is the effect of accumulating exercise on postprandial lipaemia. We propose that accumulating exercise will provide additional physical activity options for lowering postprandial TAG concentrations relevant to individuals with limited time or exercise capacity to engage in more structured forms of exercise, or longer bouts of physical activity. The benefits of accumulated physical activity might translate to a reduced risk of cardiovascular disease in the long-term.

Periodontal disease is a predictor of stroke and cognitive impairment. The association between the number of lost teeth (an indicator of periodontal disease) and silent infarcts and cerebral white matter changes on brain CT was investigated in community-dwelling adults without dementia or stroke. Dental examination and CT were performed in 438 stroke- and dementia-free subjects older than 50 yr (mean age, 63 +/- 7.9 yr), who were recruited for an early health check-up program as part of the Prevention of Stroke and Dementia (PRESENT) project between 2009 and 2010. In unadjusted analyses, the odds ratio (OR) for silent cerebral infarcts and cerebral white matter changes for subjects with 6-10 and > 10 lost teeth was 2.3 (95% CI, 1.38-4.39; P = 0.006) and 4.2 (95% CI, 1.57-5.64; P < 0.001), respectively, as compared to subjects with 0-5 lost teeth. After adjustment for age, education, hypertension, diabetes mellitus, hyperlipidemia, and smoking, the ORs were 1.7 (95% CI, 1.08-3.69; P = 0.12) and 3.9 (95% CI, 1.27-5.02; P < 0.001), respectively. These findings suggest that severe tooth loss may be a predictor of silent cerebral infarcts and cerebral white matter changes in community-dwelling, stroke- and dementia-free adults.

OBJECTIVETo observe the protection of Huanglian Jiedu Decoction (HJD) on high fat diet induced liver damage mice [hyperlipidemic mice lacking apolipoprotein E (ApoE(-/-))].

METHODSWild type mice were divided into the wild common food group and the wild hyperlipidemia group. ApoE(-/-) mice were divided into the ApoE(-/-) common food group, the ApoE(-/-) hyperlipidemia group, and the ApoE(-/-) hyperlipidemia plus HJD group, 5 in each group. In the present study, wild type mice and homozygous apoE(-/-) mice were fed with a chow diet or a high cholesterol Western diet for 4 weeks. HJD at the daily dose of 5 g/kg was given to mice in the ApoE(-/-) hyperlipidemia plus HJD group by gastrogavage. The plasma levels of total cholesterol (TC), triglyceride (TG), low density cholesterol protein (LDL-C) were detected. The pathohistological changes of the liver were observed by Eosin and Hematoxylin (HE) staining. The liver macrophages and their subtype ratios, as well as macrophage surface receptor CD206 and CD36 were detected by flow cytometry.

RESULTSTypical pathological changes of simple fatty liver were manifested in the ApoE(-/-) hyperlipidemia group, TC, TG, and LDL-C increased, the macrophage ratio increased, the expression level of macrophage surface receptor CD206 decreased, showing statistical difference when compared with the ApoE(-/-) common food group (P < 0.01, P < 0.05). The ratio of alternatively activated macrophages (M2) subpopulations was lower in the ApoE(-/-) hyperlipidemia group than in the wild common food group (P < 0.05). There was no obvious change in the expression level of CD36. After intervened by HJD for 4 weeks, there was no obvious improvement in blood lipids. But the ratio of CD206+ M2 macrophages was significantly improved, when compared with the ApoE(-/-) hyperlipidemia group (P < 0.05). The pathological changes of fatty liver were significantly attenuated.

CONCLUSIONSThe liver protection effect of HJD might be associated with immunoregulation of M2 macrophage subpopulations and injured tissue repairmen. Its immunoregulation and liver protection were independent from lipids lowering.

Dental surgery is very common, and it is important for our dental colleagues to understand the medical history and chronic medications of our co-managed patients. Antibiotic prophylaxis is currently recommended only for patients at high risk for infective endocarditis when undergoing high-risk dental procedures. Good dental hygiene can prevent more infective endocarditis than prophylactic antibiotic therapy, as transient bacteraemia is common in daily activities such as the brushing and flossing of teeth. Most dental surgeries can generally be performed on patients taking a daily dose of aspirin, but the dentist must be able to assess the risk-benefit ratio of employing local measures of haemostasis versus stopping the antiplatelet therapy. Patients on antiplatelet with recent coronary artery stenting should be referred to their primary cardiologist regarding the cessation of these agents before any surgery.

OBJECTIVETo investigate the influence of Tanyu Tongzhi (TYTZ) recipe on chemorheology, blood lipid and inflammatory factors of hyperlipidemia and myocardial ischemia-reperfusion injury in rats.

METHODSixty SD male rats were divided into 5 groups randomly, sham-operated group, model group, high dose group of reproduced by ligation of left descending artery for 30 min followed by releasing the TYTZ and low group of TYTZ. The model of MI/RI injury of the myocardium was ligation for 2 hours in rats. Serum contents of CHO, TG, HDL-L, LDL-L and whole blood viscosity, plasma viscosity and ICAM-1, TNF-alpha, IL-10 were measured after myocardial reperfusion injury.

RESULTCompared with sham-operated group, the levels of CHO, TG, LDL-L, whole blood viscosity (1.0,3.0) plasma viscosity and the contents of ICAM-1 were significantly higher, however, HDL-L, IL-10 levels were lower in model group (P < 0.01 and P < 0.05). CHO, TG, whole blood viscosity (1.0, 3.0, 30) and expression of ICAM-1, TNF-alpha were obviously lower in low group than the model group (P < 0.01 and P < 0.05).

CONCLUSIONThe TYTZ recipe can relieve reperfusion injury through regulating blood lipid, improving hemorheological characteristic and inhibiting inflammatory reaction.

OBJECTIVETo investigate the relationship between the blood lipids and risk factors such as age in middle-aged and elderly men.

METHODS1603 men aged over 50 years old who took health examinations in June 2006 in the Chinese PLA General hospital were taken into the study. The total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), fasting serum glucose (FBG), serum creatinine (Cr) and blood uric acid (UA) were detected, and the clinical data such as age, body height, body weight and blood pressure were recorded.

RESULTS(1) The detection rates of hyperlipidemia, abnormal TC, abnormal TG, abnormal HDL-c and abnormal LDL-c were 56.27%, 36.74%, 28.20%, 10.79% and 6.92% respectively, and the TC and/or TG abnormality were the majority. (2) Compared with the 50 59 years old group, the elderly men aged over 80 years old had lower detection rates of abnormal TC and abnormal HDL-c, lower levels of TC and TG and higher levels of HDL-c (P < 0.05). After adjusting for BMI, SBP, DBP, UA, FBG and CCr, the multiple regression analysis showed that the levels of TC and TG decreased by 0.097 mmol/L and 0.087 mmol/L respectively every 10 years older, while the level of HDL-c increased by 0.113 mmol/L.

CONCLUSIONThe study showed that the majority types of hyperlipidemia in middle-aged and elderly men were abnormal TC and abnormal TG. The levels of TC, TG were correlated with age positively and the HDL-c was negatively correlated with age. The blood lipids metabolism characteristics of elderly men aged over 80 years old should be considered before the treatment of hyperlipidemia.
