However, this is not the case between lipids and heart failure. Ironically, high lipid levels are associated with better outcomes in heart failure, but the mechan-isms underlying the phenomenon are not fully understood. This study was performed to test the hypothesis that reduced intestinal lipid absorption due to venous congestion may lead to low lipid levels.MethodsWe collected data of clinical characteristics, echocardio-graph, and lipid profile in 442 unselected patients with congestive heart failure. Correlations between lipid levels[including total cho-lesterol（TCL）, high-density lipoprotein cholesterol（HDL-C）, low-density lipoprotein cholesterol（LDL-C）, and triglycerides（TG）]and right ventricle end diastolic diameter （RVEDD）, left ventricle end diastolic diameter （LVEDD）, right atrium diameter （RA）, left atrium diameter （LA）, or left ventricle ejection fraction （LVEF） were analyzed using Pearson correlation and partial correlation. RVEDD, LVEDD, RA, and LA were indexed to the body surface area.ResultsThere was a significantly inverse correlation between TCL le-vels and RVEDD （r=-0.34,P〈0.001） and RA （r=-0.36,P〈0.001）. Other lipids such as LDL-C, HDL-C, and TG had asimilar inverse correlation with RVEDD and RA. All these correlations remained unchanged after adjusting for age, gender, smoking status, physical activity levels, comorbidities, and medication use.ConclusionsLipid levels were inversely correlated to RVEDD in patients with congestive heart failure; however, because this was an observational study, further investigation is needed to verify our results as wellas identify a causal relationship, if any.展开更多

Methods： We collected 120 cases about nodular goiter accompanied with gallstone and 128 cases about nodular goiter and establish 50 healthy control groups. Detected t level of hyrotropic hormone （TSH）, total triio- dothyronine （TT3）, total thyroxine in the peripheral venous blood of these cases in the three groups by using electrochemilu- minescenca immunoassay, measure level of total cholesterol （TC）, high-density tipoprotein cholesterol（HDL-C）, low-density lipoprotein cholesterol （LDL-C） and total bile acid （TBA） levels by using enzymic method, and observed the changes of thyroid function and blood lipid among the three groups. Results： The serum TT3 level in nodular goiter accompanied with gallstone group and the nodular goiter group was significantly lower than that in control group （P 〈 0.01）, and TSH level in the nodular goiter accompanied with gallstone group is significantly higher than that in control group （P 〈 0.01）, There were no statistical significance about difference of TT4 level among the three groups （P 〉 0.05）. Accordingly, TC and LDL-C level in nodular goiter accompanied with gallstone group was significantly higher than that in nodular goiter and control group （P 〈 0.01）, while TBA level in nodular goiter accompanied with gallstone group was significantly lower than that in simple nodular goiter group and control group （P 〈 0.01）. There was no statistical significance about difference of TC and LDL-C level between simple nodular goiter group and control group （P 〉 0.05）. The HDL-C level in nodular goiter accompanied with gallstone group and control group was higher than that in simple nodular goiter group （P 〈 0.01）. Conclusion： The originating etiologic factor of nodular goiter accompanied with gallstone may be related to that the decreased TT3 induced sub-clinical hypothyroidism.展开更多

The experiment was conducted in 20 hypertensive patients, evaluating the efficacy of preparations in reduced levels of cholesterol, triglycerides, body weight and BMI （body mass index）. The treatments （T1-garlic, onion and cilantro, oregano; T2-basil, parsley and garlic; and T3-garlic, onion, rosemary and coriander） were added at 1 g of hyposodic salt. The control （T4） was consisting of low sodium salt. All treatments were used for 30 days, in double blind. In outpatient care, anthropometric measurements height and biochemical determinations （time-0, 15 and 30 days） were made. Data were subjected to analysis of variance, average and regression, at 5% significance level. Ethics committee on research approved the project （CAAE 0023.0.238.000-08）. The treatments did not differ in the variables analyzed, which indicates that they are as effective as T4. The values of triglycerides and total cholesterol at 15 days and 30 days of use of spices remained within normal limits. Levels of HDL （high density lipoprotein） and LDL （low density lipoprotein） cholesterol remained in the range of the reference values. Only TI was the most effective in reducing all biochemical parameters over time. The T1 and T2 treatments were effective in weight loss and BMI reduction.展开更多

METHODS： Human U937 cells were stimulated by in- cubation with 100 nM phorbo112-myristate 13-ace- tate （PMA） for 48 h.These stimulated, monocyte-like cells were then incubated for 24 h with 50 mg/L oxi- dized low-density lipoprotein （ox-LDL, to induce foam cell formation）, together with a liver X recep- tor （LXR） agonist or with different DHI concentra- tions. MSR1 and ABCA1 mRNA levels were mea- sured by fluorescence-based quantitative PCR. RESULTS： Compared with control cells （which re- ceived only ox-LDL）, cells treated with both ox-LDL and 10 IJmol/L LXR agonist showed lower MSR1 ex-pression （but this effect was not statistically signifi- cant, P〉0.05） and higher ABCA1 expression （P〈 0.01）. Cells that received ox-LDL and 3 mL/L DHI possessed higher MSR1 mRNA levels than the con- trols, whereas cells treated with ox-LDL and higher DHI concentrations （10, 30 or 60 mL/L） showed low- er MSR1 expression levels （but the differences ob- served between DHI concentration groups were not statistically significant, P〉0.05）. ABCA1 expression in cells treated with ox-LDL and 3, 10 or 30 mL/L DHI was higher than in the control cells, and increased with increasing DHI concentration （P〈0.05）. ABCA1 expression in cells treated with ox-LDL and the highest DHI concentration tested （60 mL/L） was not significantly different from that in the controls. ABCA1 mRNA levels in cells treated with ox-LDL and DHI were similar to, or lower than, those in cells treated with ox-LDL and the LXR agonist. CONCLUSION： DHI does not affect MSR1 mRNA lev- els in ox-LDL-treated U937 cells. However, at certain concentrations （10 and 30 mL/L）, DHI significantly increases ABCA1 mRNA levels. Therefore, the an- ti-atherosclerotic action of DHI might be mediated by an increased expression of ABCA1.展开更多
