The Ability of Baseline Triglycerides and Total Cholesterol Concentrations to Predict Incidence of Type 2 Diabetes Mellitus in Chinese Men and Women:A Longitudinal Study in Qingdao, China

Objectives The purpose of this study was to assess the association between triglycerides(TG),total cholesterol(TC)at baseline,and type 2 diabetes mellitus(T2DM)incidence in a general Chinese population.Further,it aimed to evaluate the ability of TG and TC to predict T2DM incidence.Methods Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012–2015.TG,TC,and T2DM status were measured.Cox proportional hazards models were used to estimate the association between TG,TC,and T2DM incidence.The receiver operating characteristic(ROC)curve was used to evaluate the ability of TG and TC to identify T2DM participants.Results The incidence of T2DM significantly increased with TG in women and TC in both men and women(Ptrend<0.05).Univariate Cox regression indicated that higher TG{borderline high TG[hazards ratio(HR):2.05;95%confidence interval(CI):1.40,3.00]and hypertriglyceridemia[HR:2.64;95%CI:1.68,4.15]}and TC[hypercholesterolemia(HR:2.05;95%CI:1.43,2.95)]were significantly associated with increased risk of T2DM incidence in women but not in men.Multivariate Cox regression showed that hypertriglyceridemia in women(HR:1.78,95%CI:1.07,2.97),borderline high TC in men(HR:1.61,95%CI:1.04,2.48),and hypercholesterolemia in women(HR:1.68,95%CI:1.81,2.61)had a higher significant risk of T2DM incidence.The optimal cutoff values of TG were>1.15 and>1.23 mmol/L in men and women,respectively.For TC,they were>5.17 and>5.77 mmol/L in men and women,respectively.The area under the ROCs of TG and TC were 0.54(0.51–0.57)and 0.55(0.52–0.58),respectively,in men,and 0.60(0.58–0.62)and 0.59(0.56–0.61),respectively,in women.Conclusion Elevated TG and TC were risk factors for T2DM incidence.However,no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women.Hence,TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.

Comparison of low-density lipoprotein cholesterol/high-density lipoprotein cholesterol and total cholesterol/high-density lipoprotein cholesterol for the prediction of thin-cap fibroatheroma determined by intravascular optical coherence tomography

Background The correlation among the ratios of low-density lipoprotein cholesterol/high-density lipoprotein cholesterol(LDL-C/HDL-C), total cholesterol/high-density lipoprotein cholesterol(TC/HDL-C) and thin-cap fibroatheroma has not yet been established. Methods It was a single center, retrospective observational study. In total, we recruited 421 patients(82.4% men;mean age 65.73 ± 10.44 years) with one culprit vessel which determined by intravascular optical coherence tomography(OCT). The thinnest-capped fibroatheroma(TCFA) group was defined as lipid contents in > 2 quadrants, with the thinnest fibrous cap measuring less than 65 μm. Univariate and multivariate logistic regression were carried out to explore the relationship between lipoprotein ratios, TCFA and other characteristics of plaque. To compare different ratios, the area under curve(AUC) of receiver-operating characteristic(ROC) curve was assessed. Results OCT was performed in 421 patients(TCFA group(n = 109), non-TCFA group(n = 312)). LDL-C/HDL-C in the TCFA group was significantly higher than in the non-TCFA group(2.95 ± 1.20 vs. 2.43 ± 0.92, P < 0.05), as was TC/LDL in TCFA and non-TCFA group(4.57 ± 1.58 vs. 4.04 ± 1.13, P < 0.05). Both LDL-C/HDL-C(OR: 1.002(1.002-1.003), P < 0.05) and TC/HDL-C(OR: 1.001(1.001-1.004), P < 0.05) were considered independent factors for the prediction of TCFA according to the logistic regression. Based on the AUC comparison, LDL-C/HDL-C and TC/HDL-C had no significant difference statistically(LDL-C/HDL-C AUC: 0.63;TC/HDL-C AUC: 0.61;P = 0.10) for the prediction of TCFA. Conclusions LDL-C/HDL-C and TC/HDL-C could be the independent factors for predicting the presence of TCFA, indicating coronary plaque vulnerability in CAD patients. Moreover, TC/HDL-C also showed a comparative performance for the prediction of TCFA as LDL-C/HDL-C.

Pollution Tolerance of Smoke in the Distribution of Neurotransmitter Enzyme (Acetylcholine Esterase) and Total Cholesterol in Tissues of Wistar Rats

This study was designed to assess total animal exposure to non-occupational but environmentally induced smoke through short-term landfill burning toxicity tests at the biochemical levels. Exposure to municipal land-fill burning using rat model focused primarily on inhalation exposure. The environmental monitoring consisted of 60 days exposure to refuse burning by evaluating the level of protein concentrations, neurotransmitter enzyme acetylcholine esterase (AcHE), and total cholesterol in different tissues of Wistar rats. Protein concentrations tended to decrease in the brain, liver and kidney and slightly increased in the plasma while acetylcholine esterase decreased in brain and liver and increased in the kidney. The non-depletion in total cholesterol levels in the tissues tended to be due to active mobilization towards tissue metabolism. The data were sufficient to support risk assessment for human.

Association between apolipoprotein E promoter-219G/T polymorphism and total cholesterol level in patients with Alzheimer disease

BACKGROUND: Many researches have suggested that apolipoprotein E (APOE) and total cholesterol metabolism are closely related with dementia. In the supposed theory, 219 site of APOE promoter region is near gene coding region, so its polymorphism may result in the abnormality of APOE gene and protein expression, and finally lead to dementia. OBJECTIVE: To observe the association between APOE promoter-219G/T polymorphisms with serum total cholesterol in patients with Alzheimer disease, and compare it with non-dementia people. DESIGN: Case-control, comparative observation. SETTING: Department of Neurology, Fengtian Hospital of Shenyang Medical College. PARTICIPANTS: Fifty-five dementia patients including 27 males and 28 females aged (66±3) years and treated in the Department of Neurology, Fengtian Hospital were selected from January 2002 to December 2005 as the Alzheimer disease group. They all diagnosed according to the DSM-Ⅳdiagnostic criteria of Alzheimer disease instituted by American Psychiatry Association in 1994. Meanwhile, 44 none-dementia patients including 21 males and 23 females aged (66±3) years were selected from other clinical departments of Fengtian Hospital as control group. All the participants were informed the detection and agreed. METHODS: Genomic DNA was extracted from the peripheral blood of all subjects, then 'NEST'PCR, DNA sequence and enzyme digestion were adopted to detect the expression of APOE promoter-219 polymorphism, following by biomedical statistics analysis based on the clinical total cholesterol level. MAIN OUTCOME MEASURES: Polymorphism of APOE promoter-219 G/T and total cholesterol level. RESULTS: All 55 dementia patients and 44 non-dementia ones were involved in the result analysis. ①Allele and genotype frequency: The T allele frequency of the Alzheimer disease group was significantly higher than that in the control group [88.2% (97/110), 54.5% (48/88)], while G allele frequency was remarkably lower than that in the control group [11.8%(13/110), 45.5%(40/88), χ2=8.2, P < 0.01]. The TT allele frequency of the Alzheimer disease group was significantly higher than that in the control group [76% (42/55), 48% (21/44)], while GT+GG allele frequency was remarkably lower than that in the control group [24%(13/55), 52%(23/44), χ2=8.7, P < 0.01]. ②Total cholesterol level: The level of the TT genotype patients in the Alzheimer group was obviously higher than that in GT+GG genotype patients (t =2.46, P < 0.05); the cholesterol level in the two genotypes of the control group was similar (P > 0.05). CONCLUSION: TT genotype and allele T in the APOE promoter-219 polymorphisms are the sensitive gene, and genotype TT has a relationship with the increase of total cholesterol level.

Disposable Electrochemical Biosensor for Amperometric Measurement of β-hydroxybutyrate and Total Cholesterol

A new type of disposable thin-film amperometric biosensor has been developed for measurement ofβ-hydroxybutyrate and total cholesterol in serum.The biosensor consists of two plain gold electrodes mounted on a Polyethylene terephthalate (PET) substrate.The reagent solution contains bienzymes (cholesterol oxidase and cholesterol esterase for total cholesterol,β-hydroxybutyrate dehydrogenase and diaphorase forβ-hydroxybutyrate respectively) with mediator (ferricyanide) were absorption at the surface of electrodes coated by electrodepositing platinum black.The presence of the mediator lowers the applied potential and eliminates the interference from other oxidizable species enhancing the sensitivity and selectivity of the biosensor without modifying the dynamic parameters of the response.The enzymes stably retains in the matrices of platinum black film improving the performance of the mediated sensor.The linearity is observed in the concentration range from 1.0×10^(-4) to 1.0×10^(-2) mM and 1.0×10^(-4) mM to 4.99×10^(-3) mM with sensitivity of 1.958μA/mM and 2.447μA/mM respectively.The optimized biosensor exhibits excellent reproducibility and stability retaining more than 90% of its original activity over a period of one month.The simple operation of the biosensor mass-produced at low cost is expected to find clinical application and homecare.

Relationship between apolipoprotein E gene polymorphism and total cholesterol level in patients with kidney diseases

AIM: To evaluate the association between apolipoprotein E(apoE) gene polymorphism and total cholesterol(TC) level in patients with kidney diseases. METHODS: A predefined literature search was performed to collect data from the electronic databases of PubM ed, Embase and the Cochrane Library and eligible relevant studies reporting the association of apoE gene polymorphism with TC level in patients with kidney diseases were recruited for meta-analysis.RESULTS: Twenty-one studies were identified for the analysis of association between apo E gene polymorphism and TC level in patients with kidney disease. Subjects with E3E4 had a higher TC than those with E3E3 [weighted mean differences(WMD) = 2.14, P = 0.01] and subjects with E2E3 had a lower TC than those with E3E3(WMD =-1.93, P = 0.01). Subjects with ε2 had a lower TC than those with ε3(ε2 vs ε3: WMD =-1.23, P = 0.002; ε2 vs ε4: WMD =-2.77, P ﹤0.0001) and subjects with 3 had a lower TC than those with 4(WMD =-0.79, P = 0.03). CONCLUSION: Subjects with apo E E3E4 and ε4 had a higher TC level and subjects with apoE E2E3 and ε2 had a higher TC level in patients with kidney disease. However, more well-designed studies should be performed in the future to confirm these findings.

Association of cholesterol with risk of pancreatic cancer:A meta-analysis

AIM: To evaluate the effect of dietary cholesterol and serum total cholesterol(TC) on the risk of pancreatic cancer. METHODS: A literature search was performed up to June 2014 in Pub Med, EMBASE, China National Knowledge Infrastructure and China Biology Medicalliterature database for relevant articles published in English or Chinese. Pooled relative risks(RRs) with 95% confidence intervals(CIs) were calculated with a random-effects model. RESULTS: We included 14 published articles with 439355 participants for dietary cholesterol, and 6 published articles with 1805697 participants for serum TC. For the highest vs lowest category of dietary cholesterol, the pooled RR(95%CI) of pancreatic cancer was 1.308(1.097-1.559). After excluding two studies(RR > 3.0), the pooled RR(95%CI) was 1.204(1.050-1.380). In subgroup analysis stratified by study design, the pooled RRs(95%CIs) were 1.523(1.226-1.893) for case-control studies and 1.023(0.871-1.200) for cohort studies. The association of dietary cholesterol with the risk of pancreatic cancer was significant for studies conducted in North America [1.275(1.058-1.537)] and others [2.495(1.565-3.977)], but not in Europe [1.149(0.863-1.531)]. No significant association [1.003(0.859-1.171)] was found between the risk of pancreatic cancer and serum TC. CONCLUSION: Dietary cholesterol may be associated with an increased risk of pancreatic cancer in worldwide populations, except for Europeans. The results need to be confirmed further.

Aerobic Training Impacts on Blood Cholesterol of Women with Gestational Diabetes

Gestational diabetes mellitus has been identified as a major complication of pregnancies and has remained a major cause of perinatal morbidity and mortality, as well as maternal morbidity. Lipid abnormalities significantly contribute to the increased risk of cardiovascular disease and other morbidities in diabetics. One of the benefits of regular exercise is a reduction in cardiovascular risk factors through the improvement of the lipid profile and reduction of hypertension. This study investigated the effect of aerobic training on the cholesterol level of women with gestational diabetes. Thirty-four (34) women who met the inclusion criteria for this study were randomized into Exercise and Control groups. Exercise group participated in structured exercise programme, 3 sessions a week for 8 weeks with each session lasting a maximum of 60 minutes while the Control group did not participate in any form of structured exercise programme for the period of the study. Data were collected at baseline, at 4th week and at 8th week into the exercise programme. Thirty (30) of the participants completed the study and so only their data were analysed using Repeated Measure ANOVA and Independent t-test. The result showed significant changes in the total cholesterol (F[2, 28]) = 268.316, P = 0.001), of the Exercise group compared to the control. Independent t-test used to compare the lipid profile of the Experimental and Control groups showed significant difference between the means of the 2 groups at week 4 (total cholesterol (t(28) 2.164, P = 0.039, triglyceride [t(28) 3.146 P = 0.004] and week 8 (total cholesterol t(28) 4.596, P = 0.001, triglyceride t(28) 5.534, P = 0.001) but not at baseline (total cholesterol t(28) -901, P = 0.375, triglyceride t(28) 1.612, P = 0.118). It was concluded that structured aerobic exercises may have positive effect on the components of lipid profile in women with gestational diabetes.

Evaluation of antioxidant and anti-hypercholesterolemic potential of Vitis vinifera leaves

Background:Vitis vinifera is universally appreciated herb(especially fruit)for their delicacy,nutrition and conventional as functional food.In the present study,we evaluated anti-hypercholesterolemic potential of Vitis vinifera red leaves extract in experimental wistar male rats.Material and methods:Qualitative and quantitative phytochemical screening of vitis vinifera methanolic extract(VVME)and vitis vinifera aqueous extract aqueous(VVAE)extract was carried out to identify the phytoconstituents.The anti-hypercholesterolemic activity was evaluated by inducing hypercholesterolemia with high cholesterol diet for 21 days in experimental animals.During the experimental periods parameters like lipid profile,liver function test,atherogenic index and histopathological studies were analysed.Results:Total tannins,total flavonoids and total phenolic contents were found in major amount in VVME.The lipid levels were significantly attenuated by different doses of VVME and VVAE.Moreover,VVME was found more effective than VVAE and histopathological results confirmed the effectiveness of VVME.Conclusion:It can be concluded that anti-hypercholesterolemic efficacy of Vitis vinifera might be due to presence of active phytoconstituents and its antioxidant efficacy.

Causal associations between intermediate very-low-density lipoprotein cholesterol-to-total lipids ratio and peptic ulcer:A bidirectional Mendelian randomization study

BACKGROUND Previous epidemiologic investigations have consistently demonstrated a strong association between the ratio of cholesterol to total lipids in medium very-lowdensity lipoprotein(VLDL)and the occurrence of peptic ulcers(PU).However,the precise causal relationship between these factors remains ambiguous.Consequently,this study aims to elucidate the potential correlation between the ratio of cholesterol to total lipids in medium VLDL and the incidence of peptic ulcer.AIM To investigate the ratio of cholesterol to total lipids in medium very-low-density lipoprotein(VLDL)association with PU via genetic methods,guiding future clinical research.METHODS Genome-wide association study(GWAS)datasets for the ratio of cholesterol to total lipids in intermediate VLDL and peptic ulcer were retrieved from the IEU OpenGWAS project(https://gwas.mrcieu.ac.uk).For the forward Mendelian randomization(MR)analysis,72 single nucleotide polymorphisms(SNPs)were identified as instrumental variables.These SNPs were selected based on their association with the ratio of cholesterol to total lipids in intermediate VLDL,with peptic ulcer as the outcome variable.Conversely,for the inverse MR analysis,no SNPs were identified with peptic ulcer as the exposure variable and the ratio of cholesterol to total lipids in intermediate VLDL as the outcome.All MR analyses utilized inverse variance weighted(IVW)as the primary analytical method.Additionally,weighted median and MR-Egger methods were employed as supplementary analytical approaches to assess causal effects.Egger regression was used as a supplementary method to evaluate potential directional pleiotropy.Heterogeneity and multiplicity tests were conducted using the leave-one-out method to evaluate result stability and mitigate biases associated with multiple testing.RESULTS The genetically predicted ratio of cholesterol to total lipids in medium VLDL was significantly associated with an elevated risk of peptic ulcer(IVW:OR=2.557,95%CI=1.274-5.132,P=0.008).However,no causal association of peptic ulcer with the ratio of cholesterol to total lipids in medium VLDL was observed in the inverse Mendelian randomization analysis.CONCLUSION In conclusion,our study reveals a significant association between the ratio of cholesterol to total lipids in medium VLDL and an elevated risk of peptic ulcers.However,further validation through laboratory investigations and larger-scale studies is warranted to strengthen the evidence and confirm the causal relationship between these factors.

目的 探讨青年首发重度抑郁症(major depression disorder, MDD)患者继发精神病性症状的相关危险因素。方法 收集232例首发抑郁症患者首诊时的一般人口学资料、汉密尔顿抑郁量表(Hamilton depression scale, HAMD-17)、汉密尔顿焦虑量表(Hamilton anxiety scale, HAMA)得分,于次日采集肘静脉血并检测患者血糖、血脂、甲状腺功能、泌乳素和25-羟基维生素D[25(OH)D]水平,经过1年随访,根据患者是否继发精神病性症状,分为伴有精神病性症状的重度抑郁症组(PMD组,n=46)和不伴有精神病性症状的重度抑郁症组(MDD组,n=186),比较组间差异并分析各指标与精神病性症状的相关性,并探讨与青年首发PMD发生相关的危险因素。结果 PMD组未婚人数占比高于MDD组(P<0.05);PMD组HAMD-17量表得分高于MDD组(P<0.05);PMD组血清总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)及促甲状腺激素(TSH)水平高于MDD组,高密度脂蛋白胆固醇(HDL-C)及25(OH)D水平低于MDD组(P<0.05)。相关性分析显示HAMD-17评分(r=0.345)、TC(r=0.148)、LDL-C(r=0.162)及TSH水平(r=0.134)与精神病性症状呈正相关(P<0.05),已婚(r=-0.208)、HDL-C(r=-0.258)及25(OH)D水平(r=-0.276)与精神病性症状呈负相关(P<0.05)。多因素Logistic回归分析显示,未婚、HAMD-17量表得分、高TC、低HDL-C及低25(OH)D水平为MDD患者精神病性症状的独立危险因素(P<0.05)。ROC曲线提示由婚姻状况、HAMD-17得分、血清TC、HDL-C及25(OH)D水平组成的联合指标能够较好地预测MDD患者精神病性症状的发生(AUC=0.887)。结论 血清脂代谢及25(OH)D水平可能是预测青年MDD患者继发精神病性症状的的生物标志物。

双向孟德尔随机化分析总胆固醇升高风险与胆石症发生风险的关系

目的 运用双向孟德尔随机化评估总胆固醇升高风险与胆石症发生风险之间的关联。方法 总胆固醇与胆石症相关的单核苷酸多态性数据来自open gwas公共数据库,对基于全基因组相关联研究(GWAS)的所有汇总数据进行二次数据分析,分别选择与总胆固醇或者胆石症密切关联的遗传位点作为暴露或者结局变量,用Egger回归法、加权中位数法、IVW随机效应模型、IVW固定效应模型等方法进行双向孟德尔随机化分析,以OR值评价总胆固醇和胆石症之间的因果关系。结果 以总胆固醇为暴露、胆石症为结局,去除异质性前总胆固醇-胆石症的总体OR=0.91,95%CI:0.85~0.97;去除异质性后总胆固醇-胆石症的总体OR=0.93,95%CI:0.89~0.97。以胆石症为暴露、总胆固醇为结局,去除异质性前胆石症-总胆固醇的总体OR=0.20,95%CI:0.06~0.65;去除异质性后胆石症-总胆固醇的总体OR=0.28,95%CI:0.10~0.83。基因预测的总胆固醇和胆石症之间存在双向因果关系。结论 本研究证实了总胆固醇与胆石症之间的双向因果关系,随着遗传上有关能使总胆固醇水平升高的等位基因的增加,发生胆石症的风险降低。反之,随着遗传上有关能使胆石症发病增高的等位基因的增加,总胆固醇水平升高的风险降低。
