Methods Plasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey （CNHS） in 2002 which involved 14 252 participants at the age of 18 years or older. Results The mean levels of total cholesterol （TC）, triglyceride （TG） and high density lipoprotein cholesterol （HDL-C） in the participants were 3.81 retool/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas （21.0% vs. 17.7%）. The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants. Conclusion Dyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.展开更多

Methods A total of 1 452 school‐age Children of 7 to 17 years were recruited in Beijing with representative cluster sampling method. Data of anthropometric measurements including weight, height and waist circumference were collected from March to May of 2007. Body mass index（BMI）was calculated. Blood samples were obtained and lipid profiles including triglyceride （TG）, total cholesterol （TC）, high‐density lipoprotein cholesterol （HDL‐C） and low‐density lipoprotein cholesterol （LDL‐C） were measured, while glutamate‐pyruvate transaminase （ALT） and glutamic‐oxalacetic transaminase （AST） were determined to evaluate liver function. The liver was also scanned by sonography, and abnormal hepatic sonograms were documented. NAFLD was diagnosed according to the criteria recommended by the Fatty Liver and Alcoholic Liver Disease Study Group under the Chinese Liver Disease Association. Analysis of covariance （ANOVA）, Chi‐square test for trend and binary logistic regression analysis were performed. Results The dyslipidemia and ultrasonographic fatty liver deteriorated with the degree of obesity defined either by BMI or waist circumference. Compared with BMI, waist circumference contributed more to the development of dyslipidemia, fatty liver and NAFLD. The highest levels of TG, TC, LDL‐C, and lowest level of HDL‐C were seen in the mixed obese group followed by abdominal obese, peripheral obese and non‐obese ones. Adjusted for gender and age, the odds ratios （ORs） and their 95% confidence intervals of peripheral obesity, abdominal obesity and mixed obesity were 0, 10.93 （0.98‐121.96） and 79.16 （10.95‐572.44） for predicting NAFLD; 12.61 （1.24‐127.78）, 19.39 （5.23‐71.85）, and 93.21 （29.56‐293.90） for predicting ultrasonographic fatty liver; 1.78 （0.59‐5.44）, 3.01 （1.91‐4.77）, and 4.64 （3.52‐6.12） for predicting dyslipidemia, respectively compared with the non‐obese control group. The trend of hazards over groups was statistically significant （P0.01）. Conclusion The levels of lipid profile and the prevalence of NAFLD and dyslipidemia increased in parallel with the degree of obesity; As compared with the non‐obese control, the mixed obesity had the strongest association with NAFLD and dyslipidemia, followed by abdominal obesity and peripheral obesity in Chinese school‐age Children.展开更多

Methods Data about 2 568 patients with acute ischemic stroke were collected from 4 hospitals in Shandong Province from January 2006 to December 2008. National Institute of Health Stroke Scale （NIHSS） 〉10 at discharge or death was defined as the outcome. Effect of dyslipidemia on outcome in patients with acute ischemic stroke was analyzed by multivariate logistic regression analysis and propensity score-adjusted analysis, respectively. Results The serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 （1.259, 7.214）/2.655 （1.298, 5.43）, 3.157 （1.306, 7.631）/3.405 （1.621, 7.154）, and 0.482 （0.245, 0.946）/0.51 （0.282, O.921）, respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke （chi-square=8.235, P=0.411）. Conclusion Serum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.展开更多

Changes in serum and hepatic lipid parameters were evaluated. Metabolites in serum, urine and liver samples were profiled using ultra-highperformance liquid chromatography/mass spectrometry followed by multivariate statistical analysis to identify potential biomarkers and metabolic pathways.RESULTS P. kingianum significantly inhibited the HFD-induced increase in total cholesterol and triglyceride in the liver and serum. P. kingianum also significantly regulated metabolites in the analyzed samples toward normal status. Nineteen, twenty-four and thirty-eight potential biomarkers were identified in serum, urine and liver samples, respectively. These biomarkers involved biosynthesis of phenylalanine, tyrosine, tryptophan, valine, leucine and isoleucine, along with metabolism of tryptophan, tyrosine, phenylalanine, starch, sucrose, glycerophospholipid, arachidonic acid, linoleic acid, nicotinate, nicotinamide and sphingolipid.CONCLUSION P. kingianum alleviates HFD-induced dyslipidemia by regulating many endogenous metabolites in serum, urine and liver samples. Collectively, our findings suggest that P. kingianum may be a promising lipid regulator to treat dyslipidemia and associated diseases.展开更多
Diabetic dyslipidemia is a cluster of lipoprotein abnormalities characterized by increased triglyceride level, decreased high-density lipoprotein-cholesterol levels and increase in small dense low-density lipoprotein(...Diabetic dyslipidemia is a cluster of lipoprotein abnormalities characterized by increased triglyceride level, decreased high-density lipoprotein-cholesterol levels and increase in small dense low-density lipoprotein(LDL) particles. It is extremely common in type 2 diabetes(T2DM) affecting around 70 % of patients.Diabetic is a significant risk factor for atherosclerotic cardiovascular disease(ASCVD) which is the most common cause of death in the United States and LDL-cholesterol is the number 1 predictor of ASCVD events in T2DM. The purpose of this review is to discuss the pathophysiology and treatment of diabetic dyslipidemia. In this review, we have discussed both nonpharmacological and pharmacological treatment modalities including major treatment trials which have impacted the cardiovascular outcomes in patients with diabetes. Statin therapy is the mainstay of treatment to reduce ASCVD by decreasing LDL-C by 30%-49% or at least 50% depending on risk level. Attractive adjunctive therapies include Ezetimibe which is more cost effective and PCSK9 inhibitors which display potent LDL-cholesterol lowering and ASCVD event reduction. For severe hypertriglyceridemia, to avert the risk of pancreatitis, both fish oil and fenofibrate in concert with diet is the best strategy.展开更多

Among them, 54 patients with GX were assessed for Hpylori infection and their endoscopic characteristics and serum lipid profiles. The findings were compared with 54 age- and sex-matched control subjects without GX.RESULTS： The prevalence of GX was 7% （54/771） with no sex difference. GX was mainly single （64.8%） and located in the antrum （53.7%）. The mean diameter was 7 ± 3 mm. Mean body mass index （BMI） of patients with GX was 23.1 ± 2.8 and no one was above 30. Compared with the controls, lipid profiles of GX group showed significantly lower HDL-cholesterol （48.8 ± 12.3 vs 62.9 ± 40.5, P = 0.028） and higher LDL-cholesterol （112.9 ± 29.9 vs 95.9 ± 22.4, P = 0.032）. The level of total serum cholesterol, triglyceride and the existence of dyslipoproteinemia were not related to the presence of GX. However, GX showed a close relationship with endoscopically determined atrophic gastritis and histologic severity （24/53, 44.4% vs 8/54, 14.8%, P = 0.0082）. H pylori infection and bile reflux gastritis were not significantly related with GX.CONCLUSION： The prevalence of GX is 7% and it may be an increasing entity in Korea. Moreover, dyslipidemia and atrophic gastritis are found to be related to GX, but lip, H pylori infection is not.展开更多

We aimed to evaluate the co-effects of drinking and dyslipidemia on diabetes incidence in this population. Methods The present study was based on 1880 participants from a population-based prospective cohort study among Inner Mongolians living in China. Participants were classified into four subgroups according to their drinking status and dyslipidemia. Multivariate logistic regression analysis and receiver operating characteristic （ROC） curves were used to evaluate the association between alcohol drinking, dyslipidemia, and diabetes. Results During the follow-up period, 203 participants were found to have developed diabetes. The multiva riable-adjusted odds ratios （95% confidence interval） for the incidence of non-dyslipidemia/drinkers, dyslipidemia/non-drinkers, and dyslipidemia/drinkers in diabetic patients were 1.40 （0.82-2.37）, 1.73 （1.17-2.55）, and 2.31 （1.38-3.87）, respectively, when compared with non-dyslipidemia/non-drinkers. The area under the ROC curve for a model containing dyslipidemia and drinking status along with conventional factors （AUC=0.746） was significantly （P=O.003） larger than the one containing only conventional factors （AUC=0.711）. Conclusion The present study showed that dyslipidemia was an independent risk factor for diabetes, and that drinkers with dyslipidemia had the highest risk of diabetes in the Mongolian population. These findings suggest that dyslipidemia and drinkin8 status may be valuable in predicting diabetes incidence.展开更多

Several ingredients, such as polyphenolic compounds berberine, flavonoids, and curcumin, have been studied extensively by using various animal models. Effectiveness of treatment and amelioration of metabolic syndromes, including insulin resistance and dyslipidemia, has been demonstrated. This review summarizes the major checkpoints and contributing factors in regulation of exogenous and endogenous lipid metabolism, with particular emphasis centered on triglyceride-rich and cholesterol-rich lipoproteins. Available experimental evidence demonstrating the lipid-lowering effect of berberine, flavonoids and curcumin in cell culture and animal models is compiled, and the strengths and shortcomings of experimental designs in these studies are discussed.展开更多

Methods Random cluster sampling was employed in 5 areas （Lhasa, Shigatse, Shannan, Nagqu, and Nyingchi）. The levels of cholesterol （TC）, triglyceride {TG）, high-density lipoprotein cholesterol （HDL-C）, and low-density lipoprotein cholesterol （LDL-C） from blood samples were determined and DNA was extracted for genotyping and statistical analyses. Results Among 1 318 subjects aged 〉18 years enrolled in this study, 367 had dyslipidemia with a prevalence of 27.8%, of whom dyslipidemia males accounted for 33.1% and dyslipidemia females - 24.5%. Results of the correlation analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level. Subjects with rs714052 CC genotype had the lowest TG level, and the highest TG level was found in those with rs714052 TT genotype. The serum TG level in individuals with TC genotype lied in between the above two population groups. Subjects with rs964184 CC genotype had the lowest TG level, and the highest serum TG level was noted in those with rs964184 GG genotype. Conclusion Several SNPs were found to be related to the serum TG level in the Tibetan population. The APOA5 gene and MLXlPL gene may be closely associated with the serum TG level in this ethnic population group.展开更多
文摘As one of the main chronic diseases in modern society,coronary heart disease,as a major disease that affects people’s lives and health,has the characteristics of hidden onset and sudden onset.Coronary heart disease has relatively clear risk factors.Among them,blood lipid levels and blood sugar levels,as two main risk factors,play an important role in promoting the onset of coronary heart disease.The two complement each other in a vicious cycle,synergize and promote each other,promote the process of coronary atherosclerosis,thereby causing coronary heart disease.Multiple components in blood lipids and poor management of long-term blood sugar levels play a major role in specific clinical problems.This article reviews the different components of blood lipids and the effects of hyperglycemia on coronary heart disease,and initially expounds the mechanism by which blood lipids and blood sugar levels synergize each other to aggravate the risk of coronary heart disease,and combines them with relevant clinical issues,in order to help clinicians guide the prevention of coronary heart disease in terms of blood lipids and blood sugar levels.
文摘BACKGROUND The prevalence of metabolic syndrome(MetS)in adolescents is rising,correlating with the global increase in obesity and physical inactivity.AIM To examine the individual and combined associations of fitness,fatness,visceral adiposity index(VAI),and lipid ratios with MetS risk in Nigerian adolescents.METHODS This cross-sectional study included a sample of 403 adolescents(201 girls and 202 boys)aged 11-19 years.Participants were assessed for cardiorespiratory fitness,body mass index(BMI),VAI,triglyceride-to-high-density lipoprotein cholesterol ratio(TG/HDL-C),and total cholesterol-to-high-density lipoprotein cholesterol ratio(TC/HDL-C).Regression models adjusted for age and sexual maturity were used to determine the associations between these health markers and MetS risk.RESULTS Among the 177 high-risk adolescents,56.6%were at risk of central obesity,49.1%had low fitness,33.3%had dyslipidemia,and 11.7%were obese.After controlling for confounding variables,all health markers were independently and jointly associated with MetS risk,with VAI displaying the strongest explanatory power(girls:β=1.308,P<0.001;boys:β=2.300,P<0.001).Unfit girls were 5.1%more likely to be at risk of MetS,while the odds of unfit boys being at risk of MetS is 3.6.Boys with elevated VAI were 22.3 times more likely to be at risk of MetS,while the likelihood of girls with elevated VAI developing MetS risk is 2.78.CONCLUSION Health markers were independently and jointly associated with MetS risk in adolescents,with VAI and dyslip-idemia contributing most significantly.Promoting healthy eating and also aerobic activities among adolescents is crucial for improving metabolic health.
文摘With the global rise in sedentary lifestyles,obesity,and unhealthy dietary patterns,dyslipidemia has emerged as a leading modifiable risk factor for atherosclerotic cardiovascular disease.Beyond host genetics and diet,the gut microbiota has gained recognition as a critical regulator of lipid homeostasis through mechanisms involving bile acid metabolism,short-chain fatty acid signaling,and microbial modulation of inflammation.Lv et al provide a comprehensive synthesis of the diet microbe-lipid axis and therapeutic strategies,including probiotics,prebiotics,and fecal microbiota transplantation.In this correspondence,we expand on their framework by highlighting underexplored yet clinically relevant dimensions,including circadian rhythm alignment,pharmacotherapy microbe crosstalk,population-specific microbial signatures,and functional microbial phenotyping.Addressing these overlooked aspects could accelerate the translation of microbiome science into precision dyslipidemia management,with the potential to improve cardiovascular outcomes worldwide.

文摘Currently,cultivated tea plants are classified into three varieties,namely,Camellia sinensis var.sinensis,C.sinensis var.assamica,and C.sinensis var.kucha.Three tea varieties made green teas(TVGTs)are widely consumed worldwide.However,a comparative investigation of the beneficial effects,mechanism,and characteristic compounds of TVGTs has not been reported.Here,three representative tea plant varieties,namely,C.sinensis var.sinensis cv.Fuding(FD),C.sinensis var.assamica cv.Yunkang 10(YK),and C.sinensis var.kucha(KC),planted in the same garden,were used to make green teas utilizing the same standard procedure.Our findings show that the TVGTs effectively improved hyperglycemia,obesity,dyslipidemia,fatty liver,and mesenteric artery(MA)hypercontractility in mice with diabetes and obesity induced by a high-fat diet(HFD)after 11-and 22-week interventions,with YK being the most effective at 22 weeks.Liver lipidomics indicated that the TVGTs restored the glycerophospholipid and sphingolipid balance and reduced triglycerides,with YK demonstrating superior effects.The TVGTs,particularly YK,suppressed triglyceride synthesis through the ARV1-FXR-SHP-SREBP-1c pathway.A chemical profile analysis revealed that YK green tea had enriched active compounds,including caffeine,quinic acid,L-theanine,gallic acid,and catechins,compared with FD and KC green teas,which may contribute to ameliorating diabetic dyslipidemia via synergistic action.As a representative tea variety of C.sinensis var.assamica,YK green tea was found to be superior to the other two green teas in preventing and treating diabetic dyslipidemia,especially with long term consumption.These data provide important information for tea plant breeders and tea consumers.
文摘Oxidative stress is increased in metabolic syndrome and type 2 diabetes mellitus(T2DM) and this appears to underlie the development of cardiovascular disease,T2 DM and diabetic complications.Increased oxidative stress appears to be a deleterious factor leading toinsulin resistance,dyslipidemia,β-cell dysfunction,impaired glucose tolerance and ultimately leading to T2 DM.Chronic oxidative stress,hyperglycemia and dyslipidemia are particularly dangerous for β-cells from lowest levels of antioxidant,have high oxidative energy requirements,decrease the gene expression of key β-cell genes and induce cell death.If β-cell functioning is impaired,it results in an under production of insulin,impairs glucose stimulated insulin secretion,fasting hyperglycemia and eventually the development of T2 DM.

文摘Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015.Methods Data were collected from three nationally representative cross-sectional surveys.Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination.Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender.Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively;by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period.Similar trends in mean non-HDL-c and lipid-related ratios were observed.The weighted dyslipidemia prevalence linearly increased;in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2%(P for trend <0.001).Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015.Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.
文摘To investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population. Methods Plasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey （CNHS） in 2002 which involved 14 252 participants at the age of 18 years or older. Results The mean levels of total cholesterol （TC）, triglyceride （TG） and high density lipoprotein cholesterol （HDL-C） in the participants were 3.81 retool/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas （21.0% vs. 17.7%）. The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants. Conclusion Dyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

文摘Objective To explore the impacts of types and degree of obesity on non‐alcoholic fatty liver disease （NAFLD） and related lipids disturbance in Chinese school‐age children. Methods A total of 1 452 school‐age Children of 7 to 17 years were recruited in Beijing with representative cluster sampling method. Data of anthropometric measurements including weight, height and waist circumference were collected from March to May of 2007. Body mass index（BMI）was calculated. Blood samples were obtained and lipid profiles including triglyceride （TG）, total cholesterol （TC）, high‐density lipoprotein cholesterol （HDL‐C） and low‐density lipoprotein cholesterol （LDL‐C） were measured, while glutamate‐pyruvate transaminase （ALT） and glutamic‐oxalacetic transaminase （AST） were determined to evaluate liver function. The liver was also scanned by sonography, and abnormal hepatic sonograms were documented. NAFLD was diagnosed according to the criteria recommended by the Fatty Liver and Alcoholic Liver Disease Study Group under the Chinese Liver Disease Association. Analysis of covariance （ANOVA）, Chi‐square test for trend and binary logistic regression analysis were performed. Results The dyslipidemia and ultrasonographic fatty liver deteriorated with the degree of obesity defined either by BMI or waist circumference. Compared with BMI, waist circumference contributed more to the development of dyslipidemia, fatty liver and NAFLD. The highest levels of TG, TC, LDL‐C, and lowest level of HDL‐C were seen in the mixed obese group followed by abdominal obese, peripheral obese and non‐obese ones. Adjusted for gender and age, the odds ratios （ORs） and their 95% confidence intervals of peripheral obesity, abdominal obesity and mixed obesity were 0, 10.93 （0.98‐121.96） and 79.16 （10.95‐572.44） for predicting NAFLD; 12.61 （1.24‐127.78）, 19.39 （5.23‐71.85）, and 93.21 （29.56‐293.90） for predicting ultrasonographic fatty liver; 1.78 （0.59‐5.44）, 3.01 （1.91‐4.77）, and 4.64 （3.52‐6.12） for predicting dyslipidemia, respectively compared with the non‐obese control group. The trend of hazards over groups was statistically significant （P0.01）. Conclusion The levels of lipid profile and the prevalence of NAFLD and dyslipidemia increased in parallel with the degree of obesity; As compared with the non‐obese control, the mixed obesity had the strongest association with NAFLD and dyslipidemia, followed by abdominal obesity and peripheral obesity in Chinese school‐age Children.

文摘Objective To study the relationship between dyslipidemia and outcome in patients with acute ischemic stroke. Methods Data about 2 568 patients with acute ischemic stroke were collected from 4 hospitals in Shandong Province from January 2006 to December 2008. National Institute of Health Stroke Scale （NIHSS） 〉10 at discharge or death was defined as the outcome. Effect of dyslipidemia on outcome in patients with acute ischemic stroke was analyzed by multivariate logistic regression analysis and propensity score-adjusted analysis, respectively. Results The serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 （1.259, 7.214）/2.655 （1.298, 5.43）, 3.157 （1.306, 7.631）/3.405 （1.621, 7.154）, and 0.482 （0.245, 0.946）/0.51 （0.282, O.921）, respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke （chi-square=8.235, P=0.411）. Conclusion Serum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.

文摘AIM To identify the effects and mechanism of action of Polygonatum kingianum(P. kingianum) on dyslipidemia in rats using an integrated untargeted metabolomic method.METHODS A rat model of dyslipidemia was induced with a high-fat diet(HFD) and rats were given P. kingianum [4 g/(kg·d)] intragastrically for 14 wk. Changes in serum and hepatic lipid parameters were evaluated. Metabolites in serum, urine and liver samples were profiled using ultra-highperformance liquid chromatography/mass spectrometry followed by multivariate statistical analysis to identify potential biomarkers and metabolic pathways.RESULTS P. kingianum significantly inhibited the HFD-induced increase in total cholesterol and triglyceride in the liver and serum. P. kingianum also significantly regulated metabolites in the analyzed samples toward normal status. Nineteen, twenty-four and thirty-eight potential biomarkers were identified in serum, urine and liver samples, respectively. These biomarkers involved biosynthesis of phenylalanine, tyrosine, tryptophan, valine, leucine and isoleucine, along with metabolism of tryptophan, tyrosine, phenylalanine, starch, sucrose, glycerophospholipid, arachidonic acid, linoleic acid, nicotinate, nicotinamide and sphingolipid.CONCLUSION P. kingianum alleviates HFD-induced dyslipidemia by regulating many endogenous metabolites in serum, urine and liver samples. Collectively, our findings suggest that P. kingianum may be a promising lipid regulator to treat dyslipidemia and associated diseases.
文摘Diabetic dyslipidemia is a cluster of lipoprotein abnormalities characterized by increased triglyceride level, decreased high-density lipoprotein-cholesterol levels and increase in small dense low-density lipoprotein(LDL) particles. It is extremely common in type 2 diabetes(T2DM) affecting around 70 % of patients.Diabetic is a significant risk factor for atherosclerotic cardiovascular disease(ASCVD) which is the most common cause of death in the United States and LDL-cholesterol is the number 1 predictor of ASCVD events in T2DM. The purpose of this review is to discuss the pathophysiology and treatment of diabetic dyslipidemia. In this review, we have discussed both nonpharmacological and pharmacological treatment modalities including major treatment trials which have impacted the cardiovascular outcomes in patients with diabetes. Statin therapy is the mainstay of treatment to reduce ASCVD by decreasing LDL-C by 30%-49% or at least 50% depending on risk level. Attractive adjunctive therapies include Ezetimibe which is more cost effective and PCSK9 inhibitors which display potent LDL-cholesterol lowering and ASCVD event reduction. For severe hypertriglyceridemia, to avert the risk of pancreatitis, both fish oil and fenofibrate in concert with diet is the best strategy.
文摘AIM： To investigate the relationship among gastric xanthomatosis （GX）, Hpylori, dyslipidemia, and gastritis in Korea, a well-known Hpylori endemic area.METHODS： A total of 771 patients who had undergone gastroduodenoscopy by one endoscopist were included in this study. Among them, 54 patients with GX were assessed for Hpylori infection and their endoscopic characteristics and serum lipid profiles. The findings were compared with 54 age- and sex-matched control subjects without GX.RESULTS： The prevalence of GX was 7% （54/771） with no sex difference. GX was mainly single （64.8%） and located in the antrum （53.7%）. The mean diameter was 7 ± 3 mm. Mean body mass index （BMI） of patients with GX was 23.1 ± 2.8 and no one was above 30. Compared with the controls, lipid profiles of GX group showed significantly lower HDL-cholesterol （48.8 ± 12.3 vs 62.9 ± 40.5, P = 0.028） and higher LDL-cholesterol （112.9 ± 29.9 vs 95.9 ± 22.4, P = 0.032）. The level of total serum cholesterol, triglyceride and the existence of dyslipoproteinemia were not related to the presence of GX. However, GX showed a close relationship with endoscopically determined atrophic gastritis and histologic severity （24/53, 44.4% vs 8/54, 14.8%, P = 0.0082）. H pylori infection and bile reflux gastritis were not significantly related with GX.CONCLUSION： The prevalence of GX is 7% and it may be an increasing entity in Korea. Moreover, dyslipidemia and atrophic gastritis are found to be related to GX, but lip, H pylori infection is not.

文摘Objective No previous studies have evaluated the association between dyslipidemia, alcohol drinking, and diabetes in an Inner Mongolian population. We aimed to evaluate the co-effects of drinking and dyslipidemia on diabetes incidence in this population. Methods The present study was based on 1880 participants from a population-based prospective cohort study among Inner Mongolians living in China. Participants were classified into four subgroups according to their drinking status and dyslipidemia. Multivariate logistic regression analysis and receiver operating characteristic （ROC） curves were used to evaluate the association between alcohol drinking, dyslipidemia, and diabetes. Results During the follow-up period, 203 participants were found to have developed diabetes. The multiva riable-adjusted odds ratios （95% confidence interval） for the incidence of non-dyslipidemia/drinkers, dyslipidemia/non-drinkers, and dyslipidemia/drinkers in diabetic patients were 1.40 （0.82-2.37）, 1.73 （1.17-2.55）, and 2.31 （1.38-3.87）, respectively, when compared with non-dyslipidemia/non-drinkers. The area under the ROC curve for a model containing dyslipidemia and drinking status along with conventional factors （AUC=0.746） was significantly （P=O.003） larger than the one containing only conventional factors （AUC=0.711）. Conclusion The present study showed that dyslipidemia was an independent risk factor for diabetes, and that drinkers with dyslipidemia had the highest risk of diabetes in the Mongolian population. These findings suggest that dyslipidemia and drinkin8 status may be valuable in predicting diabetes incidence.

文摘Objective:To explore demographic and metabolic factors associated with increased alanine aminotransferase(ALT)activity in non-diabetic non-alcoholic fatty liver disease(NAFLD)patients.Methods:Overall 372 patients who consecutively attended to Gastroenterology Clinic of Baqiyatallah University of Medical Sciences,Tehran,Iran awere diagnosed as NAFLD entered into analysis.Exclusion criteria were having diabetes mellitus and fasting blood glucose over126 mg/dL,active hepatitis B virus infection,having hepatitis C virus positive serology,and to be under corticosteroid therapy.ALT levels were considered pathologically high when it was over30 IU/L for men and over 19 IU/L for women.Results:Bivariate analyses using t test and chisquare test showed that patients with pathologically augmented ALT levels had significantly higher NAFLD grades in their ultrasonographic evaluations(P=0.003).Moreover,these patients represented significantly higher homeostatic model assessment levels(P=0.003),levels of serum insulin(P=0.002),fasting blood glucose(P<0.001),and uric acid(P=0.02).The prevalence of insulin resistance was also higher in patients with increased serum ALT concentrations.Multifactorial logistic regression models showed that ultrasonographic grading of NAFLD(P=0.027)and insulin resistance(P=0.013)were the only variables significantly associated with abnormal ALT levels.Conclusions:This study shows that the associations of increased ALT serum levels in NAFLD patients are different from what are supposed before.By excluding diabetic patients from our population,we find that increased ALT levels are not associated with dyslipidemias but are independently associated with insulin resistance and NAFLD grading on ultrasonographic evaluations.Further studies are needed to confirm our results.

文摘There is an increasing interest and popularity of Chinese herbal medicine worldwide, which is accompanied by increasing concerns about its effectiveness and potential toxicity. Several ingredients, such as polyphenolic compounds berberine, flavonoids, and curcumin, have been studied extensively by using various animal models. Effectiveness of treatment and amelioration of metabolic syndromes, including insulin resistance and dyslipidemia, has been demonstrated. This review summarizes the major checkpoints and contributing factors in regulation of exogenous and endogenous lipid metabolism, with particular emphasis centered on triglyceride-rich and cholesterol-rich lipoproteins. Available experimental evidence demonstrating the lipid-lowering effect of berberine, flavonoids and curcumin in cell culture and animal models is compiled, and the strengths and shortcomings of experimental designs in these studies are discussed.
文摘Objective To investigate the relationship between SNPs reported in previous studies and the blood lipid level in the Tibetan population. Methods Random cluster sampling was employed in 5 areas （Lhasa, Shigatse, Shannan, Nagqu, and Nyingchi）. The levels of cholesterol （TC）, triglyceride {TG）, high-density lipoprotein cholesterol （HDL-C）, and low-density lipoprotein cholesterol （LDL-C） from blood samples were determined and DNA was extracted for genotyping and statistical analyses. Results Among 1 318 subjects aged 〉18 years enrolled in this study, 367 had dyslipidemia with a prevalence of 27.8%, of whom dyslipidemia males accounted for 33.1% and dyslipidemia females - 24.5%. Results of the correlation analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level. Subjects with rs714052 CC genotype had the lowest TG level, and the highest TG level was found in those with rs714052 TT genotype. The serum TG level in individuals with TC genotype lied in between the above two population groups. Subjects with rs964184 CC genotype had the lowest TG level, and the highest serum TG level was noted in those with rs964184 GG genotype. Conclusion Several SNPs were found to be related to the serum TG level in the Tibetan population. The APOA5 gene and MLXlPL gene may be closely associated with the serum TG level in this ethnic population group.
