Ameliorative effect of sixteen weeks endurance training on biochemical and oxidative damage in high fat diet induced obese rats

Obesity is mainly caused by consumption of high fat diet (HFD) and a lack of physical activity. Physical activity is an efficient strategy to delay development of obesity. In this studyv we tried to evaluate attenuating properties of 16 weeks endurance training on plasma oxidative stress and some biochemical parameters in HFD induced obese rats. Twenty-four male Wistar rats were randomly divided into four groups: standard diet group (SD), standard diet with endurance training group (ESD), HFD group and HFD with endurance training group (EHFD). After sixteen weeks, plasma was prepared and evaluated for measurement of different parameters. The results showed that HFD significantly decreased the activities of superoxide dismutase (33.58%), catalase (26.51%) and glutathione S-transferase (22.77%), while endurance training increased these enzymes activities. However, exercise ameliorated the increased malondialdehyde level and depletion of glutathione. In addition, it significantly reduced the increased levels of liver enzymes activities and lipid profiles. These findings suggest that endurance training has found to have beneficial effects against HFD-induced oxidative damage through increasing reduced antioxidants levels and inhibition of lipid peroxidation due to its antioxidant property. Thus, it can be considered an interesting strategy for the management of obesity related diseases.

Lipid profile among controlled and uncontrolled type-2 diabetic patients in a rural tertiary care center: a comparative study

Background: Diabetes mellitus is one of the major health problem and endemic with rapidly increasing prevalence in both developed and developing countries. It has strong association with dyslipidaemias in relation to glycaemic control and duration of the disease. Dyslipidaemias make diabetic patients more susceptible to coronary artery disease (CAD) which is the major cause of increased mortality and morbidity. Objectives were to estimate the blood glucose levels and lipid profiles among diabetics and to compare the lipid profiles among controlled and uncontrolled diabetic subjects.Methods: A cross sectional study was done including 100 diabetic subjects aged between 40 to 60 years of either sex. Patients were classified into 2 groups with 50 subjects in each group as per their glycemic index. Group 1 was controlled diabetic patients (HbA1c?7.5%) and Group 2 was uncontrolled diabetic patients (HbA1c>7.5%). Venous blood samples were collected from the subjects. The serum was used for analyzing FBS, PPBS, HbA1c and lipid profiles.Results: FBS, PPBS, HbA1c, total cholesterol, triglycerides and LDL were more in females than male patients but the mean values were not significant statistically except FBS and total cholesterol. All the lipid parameters were elevated among uncontrolled diabetic patients compared to controlled diabetic patients which was statistically significant.Conclusions: Present study concluded that the blood glucose levels and lipid parameters were elevated among uncontrolled diabetics compared to controlled diabetics strongly depicting the co-relation between the glycemic levels and lipid abnormalities. Patients should be educated to monitor regularly and control blood glucose and lipid levels.

Effects of aloe vera extracted on liver and kidney function changes induced by hydrogen peroxide in rats

Background: Aloe vera (Aloes) is a member of the Liliaceae family that is used as herbal medicine in many cultures for several purposes. The present study was designed to investigate the role of Aloe vera leaf gel extracts on lipid profiles and liver and kidney functions in rats.Methods: In this experimental investigation, a total of 20 healthy rats were divided into four following groups. Group I fed with normal diet and water. Group II administrated by 1% hydrogen peroxide with drinking water in a dark bottle prepared daily. Group III administrated with 5 ml of aloe vera oil added to 25 grams of their ratio for each rat (25 ml oil/125 g) also prepared daily with normal drinking water. Group IV also administrated with 5 ml of aloe vera oil added to 25 grams of their ratio with drinking water that contains 1% hydrogen peroxide in a dark bottle. The rats in all four groups fed for 21 days.Results: The subjects who were included in H2O2 had significantly higher concentrations of TG (146.79 vs. 73.09 mg/dL; p<0.001), cholesterol (123.60 vs. 68.90 mg/dL; p=0.001), and lower concentration of HDL (5.79 vs. 7.53 mg/dL; p<0.001) compared to the control group. While, the subjects in Aloe Vera group had lower concentration of cholesterol (55.90 vs. 68.90 mg/dL; p=0.004), and higher level of HDL (9.22 vs. 7.53 mg/dL; p<0.001). The subjects in the H2O2 had significantly higher concentrations of AST (76.64 vs. 30.04; p<0.001), ALT (64.94 vs. 23.38; p<0.001), urea (59.68 vs. 37.10; p=0.003), uric acid (0.92 vs. 0.59; p<0.001). Whereas, the subjects in Aloe Vera had substantially lower levels of AST (18.76 vs. 30.04; p=0.008).Conclusions: The present study showed that aloe vera gel extract is effective to improve the lipid profile and liver and kidney function.

Relationships between follicle-stimulating hormone level and lipid profiles in post-menopausal women / 吉林大学学报(医学版)

Objective: To explore the relationships between the follicle-stimulating hormone (FSH) level and the lipid profiles in the post-menopausal women, and to provide evidence for assessing the risk of dyslipidemia in the post-menopausal women. Methods: A total of 129 women with menopause for more than 1 year were selected as the subjects and divided into low FSH group (FSH57. 6 IU · L-1) according to the median of FSH. The data including height, weight, body mass index (BMI), age, menopausal age, duration of menopause, history of smoking, chronic diseases history of the subjects were collected; the serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-density lipoprotein cholesterol (non-HDL-C), estradiol (E2), FSH, fasting blood glucose, serum uric acid of the subjects were detected with the same method. Multivariate Logistic regression analysis was applied to analyze the relationship between the FSH level and dyslipidemia. Results: The average age of the post-menopausal women was (61. 22 + 7. 30) years, the age of menopause was (49. 97 + 4. 00) years, and the duration of menopause was (11. 16 + 7. 98) years. The proportion of post-menopausal women with dyslipidemia was 65. 9% (85/129), and there was no significant difference between two groups (P>0.05). Compared with high FSH group, the TG level of the subjects in low FSH group was increased (P<0.01) and the HDL-C level was decreased (P<0.01). There were no significant differences in the TC, LDL-C and non-HDL-C levels between two groups. The Logistic regression analysis showed that after adjusting the E2 level, age, duration of menopause, hypertension history, diabetes history, fatty liver and the BMI grade, FSH level had a negative correlation with TG increase (≥2. 3 mmol · L-1) (P<0.05). Each 10-unit increase in FSH was associated with a 29. 5% lower risk of elevated TG (95% CI: 3. 5% - 48. 5%). FSH was not significantly associated with the elevated TC (≥6. 2 mmol · L-1), elevated LDL-C (≥4. 1 mmol · L-1), decreased HDL-C (<1. 0 mmol · L-1) and elevated non-HDL-C. Conclusion: The FSH level is negatively associated with elevated TG in the post-menopausal women, suggesting that low FSH appears to be a risk factor of dyslipidemia in the post-menopausal women.

Circulating Spexin levels in pregnant women with and without gestational diabetes

Background: Several previous studies suggest that SPX plays a role in appetite control and body weight and blood glucose regulation. The aim of this study to determine SPX levels in healthy pregnancies and in gestational diabetes (GDM) and to investigate the association of SPX levels with weight gain and lipid and glucose metabolism in subjects with and without GDM.Methods: A total of 44 women with GDM and 44 women without GDM were randomly enrolled who applied for GDM screening during the 24-28th week of pregnancy. Demographics, blood glucose and lipid profiles and Spexin levels were compared between groups.Results: The mean age, BMI, and weight gain during pregnancy were higher in the GDM group. The LDL cholesterol, Hba1c, SPX and glucose levels in response to OGTT were higher in the GDM group. The SPX levels were correlated with Hba1c and blood glucose levels after OGTT, and were not correlated with the age, BMI, weight gain during pregnancy, lipid parameters, and fasting blood glucose levels in the whole study population.Conclusions: SPX levels were higher in the GDM group compared with non-GDM group and SPX levels were correlated with HbA1c levels and post-OGTT glucose levels but not with fasting glucose levels.

A study on evaluating lipid profile of patients with diabetes mellitus

Background: The diabetic patients are at increased risk to develop lipid abnormalities (hyperlipidemia). Diabetic patients who have lipid abnormalities are more prone to develop cardiovascular diseases. The aim of the current study was to estimate lipid profiles of patients with type-2 diabetes mellitus at Savar area, Dhaka, Bangladesh.Methods: This was a multidisciplinary study conducted between January to April, 2017. A total of 105 known cases of type-2 diabetic patients were investigated. Demographic characteristics and clinical data situation of the patients were taken by interview questionnaire. About 5 ml of fasting venous blood sample was collected from each subject for biochemical analysis. Data obtained were analyzed using Statistical Package of Social Sciences (SPSS-IBM) version 22.Results: Out of 105 patients, 64.8% patients were male and 35.2% were female. The mean±SD for age of patients was 47.67±5.9. The pattern of lipid abnormalities estimated was high serum triglycerides (TGs) in 58.1% patients, high serum total cholesterol (TC) in 61.9%, low high-density lipoprotein cholesterol (HDL-C) in 44.8%, high low-density lipoprotein (LDL-C) in 53.3%. Among all the variables only HDL levels was found significantly associated with age group (p=0.043). Study also revealed that, among all the variables only LDL-C level was found significantly associated with education (p=0.028) and TC level was associated with gender (p=0.003).Conclusions: Hyperlipidemia is a common complication of diabetes mellitus. Therefore maintaining good lipid profile can prevent development and progression of related complications among patient with diabetes mellitus.

Effect of Abnormal Levels of Serum Calcium Along With Lipids on Risk of Myocardial Infarction

Introduction: An association involving increased serumcalcium and deviation of blood lipid profiles is suggested byresearch workers but any connection of this association withrisks of increased acute myocardial infarction (AMI) is not yetstated. We wish to look at the association of abnormal serumcalcium and lipid levels with occurrence of myocardialinfarction.Methods: A prospective case-control study consists of 50 AMIpatients were diagnosed by cardiologists and 50 apparentlyhealthy individuals entered in the study. Serum calcium, bloodlipid profiles, and anthropometric parameters were assessed inthese study individuals. Student’s t-test was used to comparedifferent values between patients and healthy individuals.Pearson’s correlation coefficient was also used to determinethe positive association between serum calcium, blood lipidprofiles in this study population.Results: Levels of serum calcium and blood lipid profiles inAMI patients were observed significantly higher than healthyindividuals. Furthermore, serum calcium levels showed positivecorrelation with serum cholesterol levels in AMI patients.Conclusions: These findings conclude that increased serumcalcium and abnormal lipid profiles May perhaps a link withincreased risk of AMI.

Investigation of the effect of coffee on body weight, serum glucose, uric acid and lipid profile levels in male albino Wistar rats feeding on high-fructose diet / 한국실험동물학회지

Coffee is one of the most commonly consumed beverages in the worldwide and is assumed to have protective effects against metabolic syndrome. The present study was aimed at investigating the effect of coffee on body weight, serum glucose, uric acid and lipid profile levels in male albino Wistar rats feeding on high fructose diet. A post-test experimental study was conducted on a total of 30 (9–10 weeks old) male albino Wistar rats. The rats were divided into 6 groups: group I (normal control)-fed on standard chow and plain tap water only; group II (fructose control)-fed on standard chow and 20% of fructose solution; group III–VI (treatment groups)-fed on standard chow, 20% of fructose solution and treated with 71, 142, 213 and 284 mg/kg body weight/day of coffee respectively for six weeks. At the end, body weight, serum glucose, uric acid and lipid profile levels were investigated. Data was entered and cleared by epi-data software version 3.1 and analyzed by one way ANOVA followed by Tukey post hoc multiple comparison tests using SPSS V. 23.00. Statistical significance was considered at p < 0.05. The results showed that body weight, fasting serum glucose and uric acid levels significantly lowered in rats treated with 213 (p = 0.047; 0.049; 0.026) and 284 (p = 0.035; 0.029; 0.010) mg/kg body weight/day of coffee compared to fructose control group. Fasting serum triglycide (TG) and low density lipoprotein (LDL-C) levels showed significant reduction in rats treated with 284 mg/kg body weight/day of coffee as compared to fructose control group (p = 0.031; 0.046) respectively. In conclusion, treating rats with coffee decreased body weight, fasting serum glucose, uric acid, TC, TG and LDL-C, and increased HDL-C in a dose dependent manner in rats feeding on high fructose diet, suggesting that coffee consumption may be helpful in ameliorating metabolic syndrome.

Hepatic Lipase Influences Plasma Lipid Profiles and Lipoprotein Ratios in Regional Hospital Patients with Ischemic Stroke

Background: Stroke is the second most common cause of death and disability in developed Countries. Ischemic stroke is the most common, with an estimated incidence of approximately 80%.Studies have shown that dyslipidemia, including high levels of plasma or serum total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and apolipoprotein B (ApoB) and low levels of high density lipoprotein-cholesterol (HDL-C) is a risk factor for the progression of atherosclerosis and the development of cardiovascular disease. Attempts are being made to include the use of lipoprotein ratios to optimize the predictive capacity of lipid profile in risk evaluation.Objective: The objective of the present study is to evaluate the effect of hepatic lipase activity on lipid profiles and lipoprotein ratios in ischemic stroke patients.Methodology: Two hundred healthy and ischemic stroke subjects were recruited in the study after obtaining informed written consent. They were divided into six groups considering age classes. Group 1-3 were control subjects (n=100) and 4-6 were ischemic stroke subjects (n=100). Weight, height, hepatic lipase activity and plasma lipid profiles were measured and lipoprotein ratios calculated using Excel software. Statistical analyses were performed using GraphPad prism computer software version 5.00 and SPSS version 22 software programme.Results: Hepatic lipase activity in the stroke subjects was significantly (P<0.0001) lower than control subjects (P=0.0001, 20.21 ± 0.3706 µmol/h/ml vs 30.50 ± 0.3928 µmol/h/ml). The stroke subjects had significantly (P<0.05) higher SBP, DBP and BMI compared to the control. Abnormal plasma lipid parameters were obtained in the stroke subjects compared to the control subjects. The stroke subjects had significant (P<0.0001) elevated TC, TG, LDL-C, VLDL-C, Non- HDL-C, CRI-I, CRI-II, AC, TG/HDL-C and AIP as well as lower HDL-C and HDL-C/LDL-C. LDL-C/HDL-C ratio (0R=490488439.6, 95% CI=0.078 - 3.102E+18 P=0.000) is the major risk factor for the development of ischemic stroke.Conclusion: Hepatic lipase activities were lower while higher BP, BMI and dyslipidemia were obtained in the ischemic stroke subjects

Lipid profiles among Plasmodium falciparum infected, non malarial febrile patients and volunteers

Background: Acute falciparum Malaria infected patients show wide ranges of metabolic derangement including changes in serum lipid profiles. The exact mechanisms of this derangement in serum lipid profiles are still poorly understood. Objective was to study the lipid profiles among acute plasmodium falciparum infected patients.Methods: It was a Prospective observational comparative study. A total of 100 patients were consecutively taken in the study. Fifty Non- malaria febrile cases and 50 healthy volunteers were taken as control group. Baseline lipid profiles were estimated in all cases at the time of admission and at the end of one week. Data were collected and analyzed.Results: There were 100 diagnosed cases of falciparum malaria and 50 non malarial febrile and 50 healthy volunteers taken as control group. Complications was present in 50 and 50 were uncomplicated. Serum total cholesterol, HDL and LDL levels were significantly low in falciparum malaria patients, and serum TG and VLDL levels were higher than control. There were no significant changes in mean serum lipids profiles in survived and deaths cases.Conclusions: The derangement in lipid profiles in falciparum malaria was characteristic and specific for the disease. Characteristic changes were lower HDL, LDL and total cholesterol levels and higher TG and VLDL levels in comparison to control groups. Changes are more pronounced in complicated falciparum Malaria and persisting till the end of the week. These findings may be of diagnostic and prognostic value.

The Effect of Dairy Intake with Caloric Restriction on Bone Mineral Density and Lipids in Overweight/Obese Post-Menopausal Women

Aim: Women in the post-menopausal stage of life are susceptible to a number of chronic health conditions related to obesity and osteoporosis. The objective of this study was to assess the association between lipids and bone mineral density (BMD) in overweight/obese postmenopausal women placed on a dairy calcium weight-reduction diet. Methodology: A total of 56 overweight/obese postmenopausal women (mean age: 55.61±8.19; mean BMI: 32.95±6.12 kg/m2; mean weight: 86.88±17.25 kg; and mean BMD level: 1.05±0.17 g/cm2) were randomly assigned into a low dairy servings [DS-2] (800 mg/d of calcium or high diary servings [DS-4] (1400 mg/d of calcium) diet to evaluate differences in bone mineral density (BMD), body mass index (BMI) and lipid profiles (total cholesterol (TC), low-density lipoproteins cholesterol (LDL-C), high-density lipoproteins cholesterol (HDL-C), and triacylglycerol (TAG)) during a 3 month lifestyle education program. Results: For the high calcium group, the change “∆” in values at 3 months compared to baseline were: ∆BMD: 0.03 (p=0.31); ∆BMI: -0.69 (P=0.005); ∆LDL: -25.41 (p<0.001); ∆HDL: 3.49 (p=0.365); ∆TC: -22.14 (p=0.004) and ∆TAG: -1.97 (p=0.998). In the low calcium group, the 3 month – baseline changes were: ∆BMD: -0.04 (p=0.69); ∆BMI: -0.74 (P=0.002); ∆LDL: -10.86 (p=0.314); ∆HDL: 3.99 (p=0.269); ∆TC: -5.96 (p=0.769) and ∆TAG: 4.53 (p=0.97). ∆BMD was correlated with ∆LDL and ∆TC: r=-0.27 (p=0.052) and r=-0.27 (p=0.054), respectively. Conclusion: This study concludes that overweight/obese post-menopausal women who were placed on a dairy calcium weight-reduction diet during a 3 month educational program had lower in BMI, LDL, TC and higher HDL values.

Change of serum lipid profiles during antiviral therapy in chronic hepatitis C / Монголын Анагаах Ухаан

Background @#Low triglycerides and cholesterol was associated with hepatitis C virus (HCV) infection. Chronic HCV infection is the main cause of liver injury and it may influence to serum lipid levels. We aimed to evaluate the effect of antiviral treatment on the change of lipid profiles during interferon-based anti-HCV treatment. @*Material and Methods @#Totally 863 patients who completed the interferon-based antiviral therapy in Kaohsiung Medical University Hospital were included in this present study. The lipid profile measured and assessed in the baseline of the treatment and after 6 months of completion of the treatment. @*Results @#The most of the patients (81.2%) were achieved sustained virological response (SVR) by antiviral therapy. There was no significant difference between baseline triglycerides (TG) levels in the SVR group and non SVR groups. The TG levels at 6 months after completion of the treatment was significantly elevated in SVR group (102.9±57.0 mg/dL, p=0.0001) but did not elevated in non SVR group (94.5±45.6 mg/dL, p=0.690) compared with baseline TG levels. </br> After adjusting patients by four indexes for fibrosis (FIB4) in cut-off point 3.25, serum TG levels significantly increased in low FIB4 group (103.2±57.9 mg/dL, p=0.0001) but not in high FIB4 group (98.1±49.6 mg/dL, p=0.095) after 6 months end of the treatment. Serum TG level was increased greater in patients who had low FIB4 score and patients who achieved SVR (baseline 89.1±34.8 mg/dL; 6 months after treatment 104.3±59.3 mg/dL, paired T test p=0.0001). @*Conclusion@#The eradication of HCV is the main cause of the increase of lipids after Pegylated Interferon and Ribavirin treatment. </br> However advanced fibrosis also has an effect in increase of TG after the treatment.

Correlation of serum vitamin D with serum lipid in middle-aged and elderly people / 中华临床营养杂志

Objective To investigate the correlation of serum 25-hydroxy-vitamin D (25-OH-D) with lipid profiles in middle-aged and elderly patients.Methods A total of 284 patients aged over 40 years and admitted in our hospital from May 2016 to May 2017 were selected and divided into four groups according to 25-OH-D levels as the group of normal level which was not less than 30 ng/ml,the group of slight deficiency which was between 20 and 29 ng/ml,the group of moderate deficiency which was between 10 and 19 ng/ml,and the group of severely deficiency which was under 10 ng/ml.Fasting blood draw were taken to detect liver and renal functions,lipids,calcium,phosphorus and 25-OH-D levels.The level of lipids between groups was compared by one-way ANOVA,and the association between lipid profiles and 25-OH-D levels was assessed by Pearson correlation and multiple linear regression.Results The levels of triglyceride (TG),low density lipoprotein cholesterin (LDL-C) and total cholesterol/high density lipoprotein cholesterol (TC/HDL-C) were significantly higher and the HDL-C levels were significantly lower in the groups of severely deficiency,moderate deficiency and slight deficiency than in the normal group (P=0.035,P=0.015,P=0.013).The levels of serum 25-OH-D were significantly higher in HDL-C ≥ 1.04 mmol/L group than in H DL-C＜ 1.04 mmol/L group (Female P =0.007,male P=0.034).The correlation analysis showed that serum 25-OH-D level was positively associated with HDL-C (female r =0.309,P=0.002,male r =0.241,P=0.002).The multiple linear regression analysis showed that 25-OH-D level was positively correlated with HDL-C,after adjusting age,BMI,liver and kidney function,serum calcium and serum phosphorus (femaleβ =0.259,P =0.047,maleβ =0.217,P =0.049).Conclusion The incidence of vitamin D deficiency is high in middle-aged and elderly patients,and the level of serum 25-OH-D is positively correlated with HDL-C.

Relationship between weight change and the changes in blood pressure, blood glucose and blood lipid profiles in middle-aged and elderly Chinese people: a cohort study / 中华预防医学杂志

Objective@#To explore the relationship between weight change and the changes in blood pressure, blood glucose and blood lipid profiles in middle-aged and elderly Chinese people.@*Methods@#All participants were from the Dongfeng-Tongji cohort study. The study included 16 606 middle-aged and elderly Chinese people with complete information in the baseline survey in 2008 and the first follow-up survey in 2013. We collected the data on demographic characteristics, lifestyle, history of diseases and medication, and the results of medical health examinations, including height, weight, blood pressure, fasting blood glucose and lipid profiles. We divided the weight change into five groups, moderate or above weight loss (<-8.0%), slight weight loss (-8.0%, -3.1%), weight maintenance (-3.0%, 3.0%), slight weight increased (3.1%, 8.0%), and moderate or above weight increased (>8.0%). Generalized linear regression model was used to analyze the relationship between weight change and the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Subgroup analyses were used to explore the influences of gender, age and baseline BMI level on the relationship between weight change and the above-mentioned metabolic indicators.@*Results@#The average age of participants in baseline survey was (62.19±7.28) years with a range of 45 to 89 years. During the five-year period, there were 18.86% (2 633), 28.03% (4 655), 35.87% (5 956), 13.96% (2 319), 6.28% (1 043) people with moderate or above weight loss, slight weight loss, weight maintenance, slight weight increased, and moderate or above weight increased, respectively. Regression analyses showed that body weight change were positively correlated with changes in SBP, DBP, FBG, TC, LDL-C and TG, and negatively correlated with change in HDL-C (all linear trend P values were<0.05); As every 10% of weight changed, the β (95%CI) of changes in SBP (mmHg) (1 mmHg=0.133 kPa), DBP (mmHg), FBG (mmol/L), TC (mmol/L), LDL-C (mmol/L), HDL-C (mmol/L) and TG (mmol/L) were 4.94 (4.32, 5.55), 2.50 (2.11, 2.88), 0.05 (0.02, 0.08), 0.13 (0.11, 0.16), 0.14 (0.12, 0.16), -0.05 (-0.07, -0.04) and 0.16 (0.14, 0.18), respectively. Furthermore, subgroup analyses showed that weight change can lead to greater changes in blood pressure in older and overweight or obesity elderly people (all P for interaction<0.05).@*Conclusion@#Weight loss was beneficial for middle-aged and elderly people to improve the blood pressure, blood glucose and blood lipid profiles, regardless of the weight at the baseline, while weight gain was not.

A study of cardiovascular manifestation in patient with hypothyroidism

Background: Reduced production of thyroid hormone is the central feature of the clinical state termed Hypothyroidism. Hypothyroidism is associated with bradycardia, a decreased cardiac output, increased vascular resistance and perhaps a decreased sensitivity of the sympathoadrenal system. Aim and objective: To assess the cardiovascular functions in diagnosed hypothyroidism patients. Materials and methods: A total number of 70 hypothyroid patients were enrolled in this study. The clinical features, cardiovascular manifestations were studied by ECG, ECHO, chest X-ray lipid profiles. Results: Most of the cases fell in the age group of 31-40 years at a percentage of 52.9%. On analysis of 70 cases, 41% of cases were in moderate hypothyroidism group. On analyzing the pulse rate of 34% of the cases had bradycardia (PR <60/min). Mean BP- 131/84 mm Hg (Range: 118-166/66 – 102 mm Hg). Most of the patients fell into the pre-HT group which was around 66%. 24% of hypothyroid patients were hypertensive (BP >140/90 mm Hg). Lipid analysis in hypothyroid patients showed an increase in total cholesterol. 54.3% of patients had hypercholesterolemia (> 300 mg/dL). On analyzing the ECG changes in hypothyroid patients the most common finding was sinus bradycardia. It was found in 39% of cases. Next was low voltage complex which is around 34%. Normal ECG was found in 14% of patients. Least common findings were ST-T changes, RBBB and LBBB. Out of 70 cases, 12 (17.14%) patient showed enlarged cardiac silhouette (cardiomegaly). 34% of the patients had pericardial effusion. 30 % of the patients had diastolic dysfunction. Systolic dysfunction occurred in 4.3% of them, while IVST and LVPWT were seen in 14.3% and 12.9% respectively. Conclusion: Any unexplained diastolic dysfunction or pericardial effusion should be screened for hypothyroidism. Early detection of hypothyroidism and proper replacement therapy found to reverse the cardiovascular complications and thereby can decrease the morbidity and mortality.

Hyperlipidemic Inhibitory Effects of Phellinus pini in Rats Fed with a High Fat and Cholesterol Diet

This study evaluated the in vitro and in vivo hypolipidemic effects of the medicinal mushroom Phellinus pini. The methanol extract (ME) of the fruiting body of Ph. pini was active against pancreatic lipase and cholesterol esterase with 99.14% and 67.23% inhibited activity at 1.0 mg/mL, respectively. It also inhibited 81.81% and 55.33% of α-glucosidase and α-amylase activities, respectively, at 2.0 mg/mL. Hyperlipidemia as induced by feeding rats with a high fat and cholesterol diet (HFC). HFC supplemented with a 5% fruiting body powder of Ph. pini (HFC + PhP) significantly reduced plasma total cholesterol, low-density lipoprotein cholesterol, and triglycerides in rats compared with HFC. The reduced levels were comparable to rats fed the normal control diet (NC). The atherogenic index of HFC + PhP rats was significantly lower than that of the HFC rats. The excretion of fecal total lipid and cholesterol in the HFC + PhP rats was significantly higher than those in the NC and HFC rats. Histopathological examinations demonstrated scant deposition of lipids in the liver of rats fed HFC + PhP. The dietary supplementation with the fruiting body powder provided natural plasma lipid and glucose lowering effects in experimental rats without adverse effects on the plasma biochemical parameters and liver function related enzyme activities. Therefore, the hypolipidemic effects of Ph. pini may be due to the inhibitory effects on pancreatic lipase, cholesterol esterase, α-glucosidase, and α-amylase, and excretion of excess lipids and cholesterol in the feces.

Objective To assess the expression and significance of proprotein convertase subtilisin kexin 9 (PCSK9) in patients with rheumatoid arthritis (RA).Methods Sixty-five RA patients and forty-seven healthy controls were recruited in this study.The body mass index (BMI) and serum total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL),lipoprotein a,low density lipoprotein (LDL),very low density lipoprotein(VLDL),apolipoprotein A (ApoA),apolipoprotein B (ApoB) and the ratio of LDL-C/HDL-C were tested.Other parameters included disease activity score 28 (DAS28),rheumatoid factor (RF),anti-cyclic citrullinated peptide (CCP) antibody,erythrocyte sedimentation rate (ESR),c-reactive protein (CRP).Serum PCSK9 level was measured by ELISA and compared between RA patients and healthy controls.Results (1) The serum PCSK9 levels in RA patients were higher than those in healthy controls [(409.36 ±223.52) μg/L vs (292.19 ± 109.79) μg/L,P ＜ 0.05].(2) Compared with subgroup of moderate and low active disease and patients in remission,PCSK9 was significantly higher in patients with highly active disease (P ＜ 0.05).(3) The serum PCSK9 levels were positively correlated with RF,TC,TG,LDL,very low density lipoprotein (VLDL),ApoB,with r values as 0.303,0.490,0.320,0.451,0.319,0.463,respectively (P ＜ 0.05).(4) Multiple stepwise regression analysis showed that DAS28,RF,TC and LDL-C/HDL-C were relevant factors for PCSK9 in RA patients.Conclusions The serum PCSK9 level is elevated in RA patients,which is related to RF,disease activity,TC,TG,LDL,VLDL,ApoB.This suggests that PCSK9 is potentially linked to inflammatory reaction and lipid metabolism in rheumatoid arthritis.

Consumption behaviors of sugar-sweetened beverages and blood lipid profiles according to food-related lifestyles of adults in Incheon / 한국영양학회지

PURPOSE: The purpose of this study was to investigate the consumption behaviors of sugar-sweetened beverages and blood lipid profiles according to food-related lifestyles of adults in Incheon. METHODS: Subjects were recruited from 19 to 64 year old adults residing in Incheon who visited for the purpose of a health examination at D hospital. A total of 110 subjects consented to participate in this study and to allow their health examination records to be used at D hospital. Data were collected using self-administered questionnaires and anthropometric data, and blood lipid profiles were collected from health examination records. Statistical analysis was performed using the SPSS 20.0 program. RESULTS: In the factor analysis, food-related lifestyles were categorized into four factors: planned purchase seeking, taste seeking, well-being seeking, and convenience seeking. Using the K-average clustering method, food-related lifestyles of subjects were categorized into two groups: health and rationality-oriented group (HRG) and convenience purchase-oriented group (CPG). Average total scores of sugar-related nutrition knowledge in the HRG were significantly higher compared to the CPG, and average scores of consumption habits regarding sugar-containing foods in the HRG were significantly lower compared to the HRG. When subjects chose sugar-sweetened beverages, the CPG showed a significantly higher frequency of checking food labeling and considering nutrition compared to the CPG. Drinking frequency of carbonated beverages in the CPG was significantly higher compared to the HRG. CONCLUSION: There were significant differences in sugar-related nutrition knowledge and consumption habits of sugar-sweetened beverages between the two food-related lifestyle groups. These results could be useful for establishing guidelines for reducing consumption of sugar-sweetened beverages. In addition, it is necessary to continue sugar-related nutrition education by considering the food-related lifestyles of adults.

Study on the predictive effect of baseline lipid profiles on recurrent cardiovascular events after antidiabetic drugs intervention / 上海交通大学学报（医学版）

Objective · To explore the relationship between baseline lipid profiles and long-term cardiovascular outcomes after intervention with hypoglycemic drugs metformin and glipizide and to detect lipid components that can predict the long-term cardiovascular effect of metformin and glipizide.Methods· Liquid chromatography-quadrupole time of flight-mass spectrometry (LC-QTOF/MS) was used to measure 119 lipid components in baseline serum for 116 patients with type 2 diabetes (T2DM) and atherosclerotic heart disease (CHD) who were treated with glipizide (56 cases,the glipizide group)or metformin (60 cases,the metformin group).Cardiovascular complex end points (including cardiovascular death,all-cause death,nonfatal myocardial infarction,nonfatal stroke,and arterial revascularization) of all patients were followed up.The relationship between lipid components and cardiovascular complex end points was analyzed with Logistic regression analysis.The category-free net reclassification index (cfNRI) and the integrated discrimination improvement (IDI) were used to evaluate whether lipid components are helpful for predicting the recurrent cardiovascular events.Results· The differences in baseline drug distribution,clinical characteristics,and biochemical indexes between two groups were not statistically significant,except for diuretics use,serum PC (O-34:2) level,and SM (d18:0-24:0) level.Logistic regression analysis showed that baseline ChE (20:4) was a protective factor for recurrent cardiovascular events in the glipizide group (OR=0.87,P=0.039).ChE (20:4) significantly increased the cfNRI and IDI of cardiovascular complex end points by 69％ and 0.07,respectively (P=0.011,P=0.028).Baseline SM (dl 8:1-22:0) was a risk factor for recurrent cardiovascular events in the metformin group and all participants (OR=1.65,P=0.039;OR=1.64,P=0.014).SM (d18:1-22:0) significantly increased the cfNRI of cardiovascular complex end points in the metformin group and all participants by 74％ and 55％,respectively (P=0.012,P=0.005).Conclusion· Of 119 lipid components measured with LC-QTOF/MS,baseline ChE (20:4) is a protective factor and SM (d18:1-22:0) is a risk factor for cardiovascular complex end points in with T2DM and CHD patients after long-term treatment with metformin and glipizide.Both lipid components are helpful for improving the prediction of recurrent cardiovascular events.
