Methods Totally, 38 462 individuals who received health examination were enrolled in our study. We divided them into eight groups according to their ages. The levels of serum total cholesterol, triglyceride, high density lipoprotein cholesterol, and low density lipoprotein cholesterol were tested, and the relationship of blood lipid abnormity with body mass index (BMI) and fasting blood glucose was analyzed. Results The incidences of hypercholesterolemia, hyperglyceridemia, low high-density lipoprotein cholesterolemia, and hyper low-density lipoprotein cholesterolemia presented increasing trend in this population. The incidence rate of abnormity of blood lipid in health examination population increased with BMI increase. The incidence of abnormity of blood lipid in overweight and obesity population was significantly higher than that in low weight and normal weight populations (P<0.05). Meanwhile, the trend of abnormal blood lipid incidence coincided with that of abnormal fasting blood glucose. Conclusions The prevalence of overweight, obesity, and abnormity of blood lipid in Beijing presents increasing trend. The incidence of abnormity of blood lipid increases with BMI increase, in coincidence with that of fasting blood glucose.展开更多

And then to investigate the pathological characteristics of this quail model. Methods Thirty Longcheng quails were randomly divided into two groups: control group and model group (n=15). The control group quails were fed with normal diet and model group quails were fed with high fat diet for 14 days. After a 12-hour overnight fast, liver and abdominal fat at euthanasia as well as serum were collected. The levels of serum uric acid, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride, free fatty acid (FFA), and blood glucose were assayed. The activity changes of adenosine deaminase (ADA), xanthine oxidase (XOD), lipoprotein lipase (LPL), hepatic lipase (HL), and fatty acid synthetase (FAS) were analyzed. Results Compared with control group, the abdominal fat content (0.74±0.63 vs. 1.36±0.65 g, P〈0.05) and abdominal fat index (0.44%±0.30% vs. 0.85%±0.30%, P〈0.01) as well as live lipid index (3.61%±0.65% vs. 11.33%±2.14%, P〈0.01) in model group significantly increased; the levels of serum uric acid (210.61±94,76 vs. 304.25±141.94 /amol/L, P〈0.05), total cholesterol (4.20±0.51 vs. 20.10±11.25 mmol/L, P〈0.01), LDL-C (1.16±0.29 vs. 10.78±6.48 mmol/L, P〈0.01), and FFA (0.39±0.14 vs. 0.55±0.15 mmol/L, P〈0.01) in model group significantly increased; HDL-C (5.85±0.95 vs. 4.14±2.03 mmol/L, P〈0.05) significantly decreased; the levels of triglyceride and blood glucose had no significant changes (P〉0.05); the activities of ADA (9.71±3.05 vs. 17.19±5.10 U/ml, P〈0.01) and XOD (10.58±6,88 vs. 19.22+9.44 U/L, P〈0.01) in model group significantly increased; and FAS, LPL, HL had no significant changes (P〉0.05). Conclusions High fat diet can induce abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model. The changes of uric acid and lipid metabolic enzyme activities may he the pathological mechanism of abdominal fat accumulation with hyperuricemia and hypercholesterolemia.展开更多

The aim of our study is to determine the distribution of 10-year risk for ischemic cardiovascular disease (ICVD) among middle-aged Chinese adults, and to evaluate the usefulness of global risk assessment tools in the primary prevention of ICVD in Chinese population.Methods Simplified prediction tools derived from the USA-PRC Collaborative Study of Cardiovascular Epidemiology cohort were applied to the Chinese Health Examination Database (CHED) 2008. 10-year risk for ICVD was estimated in 461 157 ICVD-free subjects (264 432 male and 196 725 female) aged 35 to 59 years. Results Among the male subjects, 82.4% had a 10-year risk for ICVD of 〈5%, 14.4% of 5% to 12.1% and 3.4 of≥ 12.2%, and in female subjects, 86.7% had a 10-year risk for ICVD of 〈5%, 12.1% of 5% to 12.0% and 1.2% of ≥ 12.1%. All subjects with predicted high level ICVD risk (≥ 12.2% in male or ≥ 12.1% in female) had either remarkably elevated (≥ 160 mmHg) blood pressure, significantly increased (≥ 6.22 mml/L) total serum cholesterol or diabetes.Conclusion Using the currently recommended prediction tools, only very small proportions of middle-aged Chinese men and women who were free of ICVD would be classified into high level risk group. These prediction tools are unlikely to help for the medical intervention decision making in Chinese adult patients with hypertension and/or hypercholesterolemia展开更多

Twenty four rats weighing between 120-130 g were randomly assigned into four groups. Group A was fed normal diet, Group B, C and D were fed hypercholesterolemic diet (i.e. 20% fat + 1% cholesterol) for two weeks to establish hypercholesterolemia. Group B were maintained on hyper diet while C and D were fed 5% and 10% benniseed oil supplemented diet for four weeks. Plasma was collected and analyzed for TC (total cholesterol), HDL-C (high density lipoprotein), LDL-C (low density lipoprotein) and TG (triglycerides) levels. Linoleic acid (42.44%) and oleic acid (40.60%) were the major unsaturated fatty acid in the oil. Significant increase (P 〈 0.05) was observed in the TC, TG, LDL and LDL/HDL ratio of the hypercholesterolemic rats compared to the normal control. Supplementation with Sesamum indicum seed oil at 5% and 10% levels resulted in significant decrease (P 〈 0.05) in TC, TG, LDL and LDL/HDL ratio, and significant increase in the HDL-C. The high level of unsaturated fatty acid in the oil may in part be responsible for the hypocholesterolemic effect of the oil.展开更多

Methods: A total of 55 New-Zealand rabbits were randomly divided into control group (n=13), model group (n=14), direct moxibustion group (n=14) and medicinal herb-cake-separated moxibustion (indirect moxibustion) group (n=14). Hyperlipemia model was established by feeding the animals with specialized forage (15% vitellus powder, 5% lard, 0.5% cholesterol and common forage) for 6 weeks. Moxibustion was applied to “Juque”(CV 14), “Tianshu”(ST 25), “Fenglong”(ST 40), etc., 4 moxa-cones for every acupoint, once daily and continuously for 40 days. Serum triglyceride (TG) and total cholesterol (TCh) contents were assayed with colorimentric method. Results: Compared with control group, TCh and TG levels of model group increased significantly (P< 0.01). TCh and TG contents of direct moxibustion and indirect moxibustion groups were significantly lower than those of model group (P<0.01). Comparison between two moxibustion groups showed that serum TCh level of indirect moxibustion group was strikingly lower than that of direct moxibustion group (P<0.01). It indicated that both direct and indirect moxibustion could effectively lower hyperlipemia and the therapeutic effect of indirect moxibustion was significantly superior to that of direct moxibustion in lowering serum TCh level. Conclusion: Both direct and indirect moxibustion can regulate lipid metabolism and the therapeutic effect of medicinal herb-cake-separated moxibustion is superior to that of direction moxibustion in hyperlipemia rabbits.展开更多

Isolation of this compound was its induction into modern medicine, and its usefulness became quickly apparent as seen in its ability to combat bacterial diarrhea, type 2 diabetes, hypercholesterolemia, inflammation, heart diseases, and more. However, BBR's effects on neurodegenerative diseases remained relatively unexplored until its ability to stunt Alzheimer's disease(AD) progression was characterized. In this review, we will delve into the multi-faceted defensive capabilities and bio-molecular pathways of BBR against AD, Parkinson's disease(PD), and trauma-induced neurodegeneration. The multiple effects of BBR, some of which enhance neuro-protective factors/pathways and others counteract targets that induce neurodegeneration, suggest that there are many more branches to the diverse capabilities of BBR that have yet to be uncovered. The promising results seen provide a convincing and substantial basis to support further scientific exploration and development of the therapeutic potential of BBR against neurodegenerative diseases.展开更多

We investigated the concentrations of lipid, lipoprotein, HDL particle, oxidized low-density lipoprotein (ox-LDL) and anti-ox-LDL, and paraoxonase-1 (PON-1) activity in HD (n=33) and Tx (n=71) patients who were non-smokers without active inflammatory disease, liver disease, diabetes, or malignancy. HD patients had moderate hypertriglyceridemia, normocholesterolemia, low HDL-C, apolipoprotein A-I (apoA-I) and HDL particle concentrations as well as PON-1 activity, and increased ox-LDL and anti-ox-LDL levels. Tx patients had hypertriglyceridemia, hypercholesterolemia, moderately decreased HDL-C and HDL particle concentrations and PON-1 activity, and moderately increased ox-LDL and anti-ox-LDL levels as compared to the reference, but ox-LDL and anti-ox-LDL levels and PON-1 activity were more disturbed in HD patients. However, in both patient groups, lipid and lipoprotein ratios (total cholesterol (TC)/HDL-C, LDL-C/HDL-C, triglyceride (TG)/HDL-C, HDL-C/non-HDL-C, apoA-I/apoB, HDL-C/apoA-I, TG/HDL) were atherogenic. The Spearman's rank coefficient test showed that the concentration of ox-LDL correlated positively with HDL particle level (R=0.363, P=0.004), and negatively with TC (R=-0.306, P=0.012), LDL-C (R=-0.283, P=0.020), and non-HDL-C (R=-0.263, P=0.030) levels in Tx patients. Multiple stepwise forward regression analysis in Tx patients demonstrated that ox-LDL concentration, as an independent variable, was associated significantly positively with HDL particle level. The results indicated that ox-LDL and de- creased PON-1 activity in Tx patients may give rise to more mildly-oxidized HDLs, which are less stable, easily undergo metabolic remodeling, generate a greater number of smaller pre-13-HDL particles, and thus accelerate reverse cholesterol transport, which may be beneficial for Tx patients. Further studies are necessary to confirm this.展开更多

The effectiveness of pitavastatin in reversing carotid atherosclerosis associated with hypercholesterolemia (HC) is un-known. Objectives: To explore the simultaneous effects of pitavastatin calcium on brachial arterial flow-mediated vasodilatation (FMD), carotid intima-media thickness (IMT), and arterial stiffness (β), three surrogate markers of ath-erosclerosis were studied in HC patients. Methods:A randomized, double-blind trial was performed with 40 HC sub-jects who fulfil ed the inclusion/exclusion criteria. Patients were given pitavastatin calcium 1 mg/d (Group 1) or 2 mg/d (Group 2) for 8 weeks. There were 20 patients in each group, and 30 gender-and age-matched healthy subjects as controls were recruited. FMD of the brachial artery, carotid IMT, and arterial stiffness indicated byβwere measured at baseline and at 8 weeks after starting pitavastatin calcium therapy using ultrasound techniques. Biochemical tests were also made on al subjects. Results: At baseline, higher total cholesterol (TC) and low-density lipoprotein cho-lesterol (LDL-C), reduced FMD, and increasedβand IMT were observed in HC patients (P0.05). Significant negative interactions between TC/LDL and FMD (P〈0.05–0.001), positive interactions between TC and IMT (P=0.003) and between TC/LDL and β (P〈0.001–0.000) were found. Conclusions: Treatment with pitavastatin calcium exerted fa-vorable effects on endothelial function and arterial stiffness. It also improved carotid atherosclerosis in patients with HC.展开更多

文摘Fatty acid composition of Sesamum indicum oil was determined by gas chromatography and the response of hypercholesterolemic rats to diet supplemented with Sesamum indicum seed oil was investigated. Twenty four rats weighing between 120-130 g were randomly assigned into four groups. Group A was fed normal diet, Group B, C and D were fed hypercholesterolemic diet (i.e. 20% fat + 1% cholesterol) for two weeks to establish hypercholesterolemia. Group B were maintained on hyper diet while C and D were fed 5% and 10% benniseed oil supplemented diet for four weeks. Plasma was collected and analyzed for TC (total cholesterol), HDL-C (high density lipoprotein), LDL-C (low density lipoprotein) and TG (triglycerides) levels. Linoleic acid (42.44%) and oleic acid (40.60%) were the major unsaturated fatty acid in the oil. Significant increase (P 〈 0.05) was observed in the TC, TG, LDL and LDL/HDL ratio of the hypercholesterolemic rats compared to the normal control. Supplementation with Sesamum indicum seed oil at 5% and 10% levels resulted in significant decrease (P 〈 0.05) in TC, TG, LDL and LDL/HDL ratio, and significant increase in the HDL-C. The high level of unsaturated fatty acid in the oil may in part be responsible for the hypocholesterolemic effect of the oil.
文摘Objective: To study the effect of medicinal herb-cake-separated moxibustion on serum lipoprotein levels in hyperlipemia rabbits. Methods: A total of 55 New-Zealand rabbits were randomly divided into control group (n=13), model group (n=14), direct moxibustion group (n=14) and medicinal herb-cake-separated moxibustion (indirect moxibustion) group (n=14). Hyperlipemia model was established by feeding the animals with specialized forage (15% vitellus powder, 5% lard, 0.5% cholesterol and common forage) for 6 weeks. Moxibustion was applied to “Juque”(CV 14), “Tianshu”(ST 25), “Fenglong”(ST 40), etc., 4 moxa-cones for every acupoint, once daily and continuously for 40 days. Serum triglyceride (TG) and total cholesterol (TCh) contents were assayed with colorimentric method. Results: Compared with control group, TCh and TG levels of model group increased significantly (P< 0.01). TCh and TG contents of direct moxibustion and indirect moxibustion groups were significantly lower than those of model group (P<0.01). Comparison between two moxibustion groups showed that serum TCh level of indirect moxibustion group was strikingly lower than that of direct moxibustion group (P<0.01). It indicated that both direct and indirect moxibustion could effectively lower hyperlipemia and the therapeutic effect of indirect moxibustion was significantly superior to that of direct moxibustion in lowering serum TCh level.

文摘Objective To compare and rank the clinical effects of different acupuncture and related therapies on hyperlipidemia patients.Methods We used network meta-analysis(NMA)to evaluate direct and indirect effects in studies of acupuncture and related therapies for hyperlipidemia.Databases PubMed,EMBASE,Cochrane Library,the China Biology Medicine(CBM),the China National Knowledge Infrastructure(CNKI),Wanfang Data and the Chinese Scientific Journal Database(VIP)were searched to collect randomized controlled trials(RCTs)of acupuncture and related therapies in the treatment of hyperlipidemia.The data were analyzed using Stata 15.0 and WinBUGS 1.4.3 software after two researchers independently screened the literature,extracted the data,and assessed the risk of bias in the included studies.Results We analyzed a total of 36 eligible studies that included 3124 patients,involving 12 types of acupuncture and related therapies and comprehensive therapies.The results of the NMA showed that:for the total cholesterol(TC),acupoint catgut embedding(ACE),simple acupuncture(ACU),acupoint injection(AI),electroacupuncture(EA),western medicine of statins(WM),and combination of acupuncture and related therapies(combined therapies)were all more effective than placebo(P<0.05).For triacylglycerol(TG),ACU,EA,warming acupuncture(WA),WM and combined therapies were better than placebo(P<0.05),while WA was better than Chinese herb(CH)(P<0.05).For low-density lipoprotein cholesterol(LDL-C),combined therapies were more effective than lifestyle modification(LM)(P<0.05).For high-density lipoprotein cholesterol(HDL-C),auricular acupoint stimulation(AAS),ACE,ACU,AI,CH,EA,LM,moxibustion(MOX),WM,combined therapies and placebo were all worse than WA(P<0.05),while WM and combined therapies were better than ACU(P<0.05).Combined ranking results suggest that ACU and combined therapies may be the optimal intervention.Conclusions The efficacy of all kinds of acupuncture-related therapies in patients with hyperlipidemia is better than lifestyle changes.However,for different outcome indicators,all kinds of acupuncture-related therapies have their advantages and disadvantages,and comprehensive ranking results suggest that ACU and combined therapies may be the optimal intervention.
文摘Berberine(BBR) is an organic small molecule isolated from various plants that have been used in traditional Chinese medicine. Isolation of this compound was its induction into modern medicine, and its usefulness became quickly apparent as seen in its ability to combat bacterial diarrhea, type 2 diabetes, hypercholesterolemia, inflammation, heart diseases, and more. However, BBR's effects on neurodegenerative diseases remained relatively unexplored until its ability to stunt Alzheimer's disease(AD) progression was characterized. In this review, we will delve into the multi-faceted defensive capabilities and bio-molecular pathways of BBR against AD, Parkinson's disease(PD), and trauma-induced neurodegeneration. The multiple effects of BBR, some of which enhance neuro-protective factors/pathways and others counteract targets that induce neurodegeneration, suggest that there are many more branches to the diverse capabilities of BBR that have yet to be uncovered. The promising results seen provide a convincing and substantial basis to support further scientific exploration and development of the therapeutic potential of BBR against neurodegenerative diseases.

文摘Disturbances in the metabolism of lipoprotein profiles and oxidative stress in hemodialyzed (HD) and post-renal transplant (Tx) patients are proatherogenic, but elevated concentrations of plasma high-density lipoprotein (HDL) reduce the risk of cardiovascular disease. We investigated the concentrations of lipid, lipoprotein, HDL particle, oxidized low-density lipoprotein (ox-LDL) and anti-ox-LDL, and paraoxonase-1 (PON-1) activity in HD (n=33) and Tx (n=71) patients who were non-smokers without active inflammatory disease, liver disease, diabetes, or malignancy. HD patients had moderate hypertriglyceridemia, normocholesterolemia, low HDL-C, apolipoprotein A-I (apoA-I) and HDL particle concentrations as well as PON-1 activity, and increased ox-LDL and anti-ox-LDL levels. Tx patients had hypertriglyceridemia, hypercholesterolemia, moderately decreased HDL-C and HDL particle concentrations and PON-1 activity, and moderately increased ox-LDL and anti-ox-LDL levels as compared to the reference, but ox-LDL and anti-ox-LDL levels and PON-1 activity were more disturbed in HD patients. However, in both patient groups, lipid and lipoprotein ratios (total cholesterol (TC)/HDL-C, LDL-C/HDL-C, triglyceride (TG)/HDL-C, HDL-C/non-HDL-C, apoA-I/apoB, HDL-C/apoA-I, TG/HDL) were atherogenic. The Spearman's rank coefficient test showed that the concentration of ox-LDL correlated positively with HDL particle level (R=0.363, P=0.004), and negatively with TC (R=-0.306, P=0.012), LDL-C (R=-0.283, P=0.020), and non-HDL-C (R=-0.263, P=0.030) levels in Tx patients. Multiple stepwise forward regression analysis in Tx patients demonstrated that ox-LDL concentration, as an independent variable, was associated significantly positively with HDL particle level. The results indicated that ox-LDL and de- creased PON-1 activity in Tx patients may give rise to more mildly-oxidized HDLs, which are less stable, easily undergo metabolic remodeling, generate a greater number of smaller pre-13-HDL particles, and thus accelerate reverse cholesterol transport, which may be beneficial for Tx patients. Further studies are necessary to confirm this.

文摘Background: Statins have proven efficacy in inhibiting the onset and progress of atherosclerosis. The effectiveness of pitavastatin in reversing carotid atherosclerosis associated with hypercholesterolemia (HC) is un-known. Objectives: To explore the simultaneous effects of pitavastatin calcium on brachial arterial flow-mediated vasodilatation (FMD), carotid intima-media thickness (IMT), and arterial stiffness (β), three surrogate markers of ath-erosclerosis were studied in HC patients. Methods:A randomized, double-blind trial was performed with 40 HC sub-jects who fulfil ed the inclusion/exclusion criteria. Patients were given pitavastatin calcium 1 mg/d (Group 1) or 2 mg/d (Group 2) for 8 weeks. There were 20 patients in each group, and 30 gender-and age-matched healthy subjects as controls were recruited. FMD of the brachial artery, carotid IMT, and arterial stiffness indicated byβwere measured at baseline and at 8 weeks after starting pitavastatin calcium therapy using ultrasound techniques. Biochemical tests were also made on al subjects. Results: At baseline, higher total cholesterol (TC) and low-density lipoprotein cho-lesterol (LDL-C), reduced FMD, and increasedβand IMT were observed in HC patients (P0.05). Significant negative interactions between TC/LDL and FMD (P〈0.05–0.001), positive interactions between TC and IMT (P=0.003) and between TC/LDL and β (P〈0.001–0.000) were found. Conclusions: Treatment with pitavastatin calcium exerted fa-vorable effects on endothelial function and arterial stiffness. It also improved carotid atherosclerosis in patients with HC.
