The prevalence of metabolically healthy obesity and its transition into the unhealthy state: A 5-year follow-up study.

People with metabolically healthy obesity (MHO) are at risk of developing cardiometabolic diseases. We investigated the prevalence of MHO and factors influencing its transition into a metabolically unhealthy state (MUS). This study was conducted as part of the Kerman Coronary Artery Disease Risk Factor Study (KERCADRS). From 2014 to 2018, 9997 people were evaluated. The obesity and metabolic status of the MHO participants were re-examined after 5 years of their initial participation in the study. Out of 347 MHO, 238 individuals were accessed at follow-up. Twenty-nine (12.2%) had metabolic unhealthy normal weight (MUNW), 169 (71.0%) had metabolic unhealthy obesity (MUO), and the others had healthy metabolic state. Among age, total cholesterol, diastolic blood pressure and triglyceride (TG) variables, the baseline serum TG level was associated with a significant increase in the risk of developing MUS during 5 years (p <.05). The TG level optimal cut-off point for predicting the development into MUS was 107 mg/dL with 62.1% sensitivity and 77.5% specificity (AUC = 0.734, p <.001). A high percentage of MHO people transit into MUS during 5 years. A TG level higher than 107 mg/dL can help to identify people at a higher risk of developing into MUS.

Prognostic significance of Pleural Fluid triglyceride levels based on a low-Fat Diet Management Strategy in patients with Chylothorax following pulmonary resection.

BACKGROUND: Chylothorax is a postoperative complication in patients with lung cancer. Diet-control approaches have been the mainstay for managing this condition. However, a surgical intervention is needed for the patients if conservative treatment is ineffective. Because of the lack of accurate indicators to assess the prognosis of the postoperative complication at an early stage, the criteria of surgical treatment were not consistent. METHODS: We reviewed 2942 patients who underwent pulmonary resection and lymph node dissection for primary lung cancer at our hospital between March 2021 and December 2022. The prognostic implications of clinical indicators were assessed in patients with postoperative chylothorax who were managed with a low-fat diet. Binary logistic regression was used to explore the predictive value of these indicators for patient prognosis. RESULTS: Postoperative chylothorax occurred in 108 patients and 79 patients were treated with a low-fat diet management while 29 patients were managed with TPN. In contrast to drainage volume, the pleural effusion triglyceride level after 2 days of low-fat diet exhibited enhanced predictive efficacy in predicting patient prognosis. When the pleural fluid triglyceride level of 1.33 mmol/L was used as the diagnostic threshold for prognosis, the sensitivity and specificity reached 100% and 80.6%, respectively. CONCLUSIONS: The pleural effusion triglyceride level after 2 days of low-fat diet can serve as a valuable prognostic indicator in patients undergoing lung surgery and experiencing chylothorax. This predictive approach will help thoracic surgeons to identify patients with poor prognosis in a timely manner and make decision to perform necessary surgical interventions.

Factors predicting the adhesion and prolonged lost days of work in patients with extensor tendon adhesion of the hand.

Objective: Extensor tendon adhesion receive less attention recently. This study aims to analyze influencing factors of adhesion and prolonged lost days of work in patients with extensor tendon adhesion of the hand. Method: We performed a retrospective study in patients with extensor tendon injuries who underwent primary surgical repair and early rehabilitation. We observed the differences between non-tendon adhesion and adhesion patients after surgical repair, and used the receiver operating characteristic curve to distinguish them. Then we explored the influencing factors of adhesion. In addition, we studied the lost days of work and the influencing factors. Results: A total of 305 patients were included. 24.6% patients appeared tendon adhesion and the mean lost days of work was 12 weeks. MHISS scores, VAS scores, occupation and blood triglyceride level were the influencing factors of adhesion. The adhesion patients have increased MHISS scores (p < 0.001), VAS scores (p < 0.001), blood triglyceride levels (p < 0.001) and lost days of work (p < 0.001) than non-tendon adhesion. The optimal cut-off value of blood triglyceride level to distinguish non-tendon adhesion from adhesion was 1.625 mml/L, and MHISS scores was 20.5. Smoking, MHISS scores, blood triglyceride levels were the influencing factors of lost days of work in adhesion patients. There was positive correlation between lost days of work and triglyceride level (r = 0.307, p = 0.007), and MHISS scores (r = 0.276, p = 0.016). Conclusion: To minimize the occurrence of adhesion, doctors should pay attention to patients with higher MHISS and VAS scores, blood triglyceride levels, especial for the blue-collar and unemployed one. High triglyceride level may be a new influencing factor.

Serum triglyceride levels and incidence of hypertension in a general Japanese population: ISSA-CKD study.

The aim of this study was to clarify the relationship between fasting and nonfasting serum triglyceride (TG) levels and the incidence of hypertension in a general Japanese population. We conducted a population-based retrospective cohort study using annual health check-up data of residents of Iki City, Nagasaki Prefecture, Japan. A total of 3202 participants without hypertension at baseline were included in the present analysis. TG levels were classified as quartile 1 (<0.82 mmol/L), quartile 2 (0.83-1.13 mmol/L), quartile 3 (1.14-1.70 mmol/L) and quartile 4 (≥1.71 mmol/L) for men, and as quartile 1 (<0.70 mmol/L), quartile 2 (0.71-0.96 mmol/L), quartile 3 (0.97-1.34 mmol/L) and quartile 4 (≥1.35 mmol/L) for women. The outcome was incident hypertension. During an average follow-up of 4.4 years, 983 participants developed hypertension, according to the Cox proportional hazards model. The annual incidence of hypertension increased with an elevation in TG levels for men (5.88% in quartile 1, 8.30% in quartile 2, 7.62% in quartile 3, and 9.82% in quartile 4). This association was significant, even after adjustment for other risk factors: hazard ratio 1.41 [95% CI 1.07-1.85] for quartile 2, 1.30 [0.99-1.71] for quartile 3, and 1.59 [1.22-2.08] for quartile 4 compared with quartile 1 (p = 0.041 for trend). In contrast, there was no clear association between serum TG levels and the incidence of hypertension after adjustment for confounding factors among women (p = 0.240 for trend). High levels of serum TG were associated with the future incidence of hypertension in a general population of Japanese men but were not associated with that in women. Casual serum triglyceride levels and incidence of hypertension in a general Japanese population: ISSA-CKD study.

Triglyceride Level- and MTHFR- Specific Mediation Effect of Handgrip Strength on the Association of Dietary Protein Intake and Cognitive Function in the Chinese Elderly.

BACKGROUND: Recent findings suggest that both dietary protein intake and hand grip strength (HGS) were associated with cognitive function, however, few studies have been devoted specifically to the mediation effect of HGS on the association of dietary protein with cognitive function. OBJECTIVES: To confirm the hypothesis that HGS mediated the association of dietary protein intake with cognitive function in the elderly, which was modified by triglyceride level and methylenetetrahydrofolate reductase (MTHFR) gene status. METHODS: This cross-sectional study included 3,268 participants. Dietary protein intake, HGS, and cognitive function were collected by food frequency questionnaires (FFQ), grip measurements and mini mental state examination (MMSE), respectively. In this mediation analysis, dietary protein intake was entered as independent variable, HGS was entered as mediator, and cognitive function was entered as dependent variable. RESULTS: HGS significantly mediated the associations of dietary protein (ß = 0.0013, 95% CI: 0.0007, 0.0022), animal protein (ß = 0.0024, 95% CI: 0.0012, 0.0037), and plant protein intake (ß = 0.0011, 95% CI: 0.0001, 0.0023) with cognitive function in total participants, with the mediated proportion of 16.19%, 12.45% and 20.57%, respectively. Furthermore, significant mediation effects of HGS on the associations of dietary protein, animal protein, and plant protein intake with MMSE score were found in the elderly without hypertriglyceridemia or in MTHFR C677T CC/CT carriers. CONCLUSION: This study suggested that HGS mediated the association of dietary protein intake with cognitive function, and this mediation effect was modified by triglyceride level and MTHFR C677T gene status.

Pleiotropic Effects of Common and Rare GCKR Exonic Mutations on Cardiometabolic Traits.

BACKGROUND: The common non-synonymous mutation of the glucokinase regulator (GCKR) gene, namely rs1260326, is widely reported to have pleiotropic effects on cardio-metabolic traits and hematological parameters. OBJECTIVE: This study aimed to identify whether other GCKR variants may have pleiotropic effects independent of the rs1260326 genotypes. METHODS: In total, 81,097 Taiwan Biobank participants were enrolled for the regional plot association studies and candidate variant analysis of the region around the GCKR gene. RESULTS: The initial candidate variant approach showed the significant association of the rs1260326 genotypes with multiple phenotypes. Regional plot association analysis of the GCKR gene region further revealed genome-wide significant associations between GCKR variants and serum total and low-density lipoprotein cholesterol; triglyceride, uric acid, creatinine, aspartate aminotransferase, γ-Glutamyl transferase, albumin, and fasting plasma glucose levels; estimated glomerular filtration rate; leukocyte and platelet counts; microalbuminuria, and metabolic syndrome, with rs1260326 being the most common lead polymorphism. Serial conditional analysis identified genome-wide significant associations of two low-frequency exonic mutations, rs143881585 and rs8179206, with high serum triglyceride and albumin levels. In five rare GCKR exonic non-synonymous or nonsense mutations available for analysis, GCKR rs146175795 showed an independent association with serum triglyceride and albumin levels and rs150673460 showed an independent association with serum triglyceride levels. Weighted genetic risk scores from the combination of GCKR rs143881585 and rs146175795 revealed a significant association with metabolic syndrome. CONCLUSION: In addition to the rs1260326 variant, low-frequency and rare GCKR exonic mutations exhibit pleiotropic effects on serum triglyceride and albumin levels and the risk of metabolic syndrome. These results provide evidence that both common and rare GCKR variants may play a critical role in predicting the risk of cardiometabolic disorders.

Short-term energy drink consumption influences plasma glucose, apolipoprotein B, body mass index and pulse rate among students.

OBJECTIVE: Energy drinks are becoming more popular every year, particularly among young adults such as college students, despite evidence that they have harmful health effects. The effect of energy drink consumption on plasma glucose, serum apolipoproteins, and triglyceride levels in students was investigated. METHODS: In order to test this, we chose two representative types of energy drinks in Nigeria, namely fearless and predator. These energy drinks are brand names of non-alcoholic beverages aimed to provide energy. 30 students, apparently healthy male human subjects aged 18 to 30 years who gave informed consent to the research work were randomly selected and divided into two groups: Group A (fearless energy drink consumers, n=15) and Group B (predator energy drink consumers, n=15).   RESULTS: The results demonstrated significant reductions in pulse rate (86.00±41.32 vs. 78.87±27.72; p=0.03) and BMI (21.41±1.93 vs. 21.7±12.02; p=0.00) as compared to baseline values after one month of "fearless energy drink" consumption. Plasma glucose levels were significantly higher (97.53±10.62 vs. 88.80±11.33; p=0.01) and Apo B levels were significantly lower (21.41±1.93 vs. 21.71±2.02; p=0.00) following two weeks of fearless energy drink consumption than in baseline. In addition, BMI and Apo B levels were significantly lower after two weeks of predator energy drink consumption, but plasma glucose levels were significantly higher after two weeks and one month of predator energy drink consumption, respectively (p<0.05). SBP, DBP, TG and Apo A levels did not differ significantly in both fearless and predator energy drink consumers at baseline and after the study period respectively (p>0.05). CONCLUSION: This study has shown that the consumption of energy drinks causes significant alterations in BMI, pulse rate, plasma glucose and apolipoprotein B levels which may have important clinical consequences for energy drink consumers.

Cholesterol and triglyceride levels in first-episode patients with major depressive disorder: A meta-analysis of case-control studies.

BACKGROUND: Lipid profile disturbances are frequently observed in major depressive disorder (MDD) and constitute to high mortality rates. However, less is known about whether this risk is present in patients with first-episode MDD. Therefore, this meta-analysis was conducted to examine if lipid parameters differed between healthy controls and first-episode MDD patients. METHODS: Cochrane Library, PubMed, PsycINFO, EMBASE, Chinese Journal Net, and WanFang databases were searched from inception to October 23, 2018. The primary outcomes were triglycerides, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and total cholesterol levels. RESULTS: A total of 11 case-control studies compared 690 subjects with first-episode MDD and 614 healthy controls were included and analyzed. Compared to healthy controls, patients with first-episode MDD were significantly associated with higher triglyceride (SMD = 0.29, 95% CI: 0.09, 0.48, P = 0.004) and lower HDL cholesterol levels (SMD = -0.54, 95% CI: -0.86, -0.22, P = 0.001). Subgroup analyses revealed that first-episode MDD patients with higher triglyceride and lower HDL levels were found only in Chinese and plasma group when compared to healthy controls (P < 0.05). Meta-regression analysis showed that the significant heterogeneity for triglyceride and HDL cholesterol was partly explained by the quality of study. No significant difference was found in LDL cholesterol and total cholesterol levels between the two groups. LIMITATIONS: Heterogeneity was relatively high among the included studies. CONCLUSIONS: Elevated triglyceride and decreased HDL cholesterol levels may be associated with first-episode MDD. Findings support early lipid monitoring and interventions targeting healthy lifestyle.

Triglyceride Level Is an Independent Risk Factor in First-Attacked Neuromyelitis Optica Spectrum Disorders Patients.

Objective: To investigate prospective associations between triglyceride (TG) level and prognosis of first-attacked patients with neuromyelitis optica spectrum disorders (NMOSD). Methods: This retrospective study included 196 patients newly diagnosed with NMOSD from June 2014 to December 2018. Data of clinical parameters, including age of onset, sex, BMI, blood lipid levels, anti-aquaporin-4 status, serum glucose level, therapy regimens, comorbidities, initial Expanded Disability Status Scale (EDSS), relapses, and outcomes were collected. We used logistic regression models to examine the associations among relevant clinical factors and outcomes, and statistical analyses were performed using the SPSS 23.0 software. Results: Compared with the high TG group, residual EDSS was relatively lower in the normal TG group (median 1.0 vs. 2.0, P = 0.002). In the univariate analysis, TG level was positively correlated with outcomes (OR 1.75, 95% CI 1.18-2.60, P = 0.005) and relapses (OR 1.57, 95% CI 1.07-2.31, P = 0.02). Our stratified analysis suggested that patients with normal BMI (OR 4.90, 95% CI 2.10-11.44, P = 0.001) were closely correlated with poor recovery owing to increased TG level. In the multivariate analysis, a statistically significant association still existed between TG level and outcomes (OR 3.44, 95% CI 1.02-11.64; P = 0.040) after adjusting for various variables. Conclusions: In first-attacked NMOSD patients, TG level was positively associated with poor recovery. Early monitoring and treatment of elevated TG level in NMOSD patients are important.

Pleiotropic association of LIPC variants with lipid and urinary 8-hydroxy deoxyguanosine levels in a Taiwanese population.

BACKGROUND: Hepatic lipase (HL, encoded by LIPC) is a glycoprotein primarily synthesized and secreted by hepatocytes. Previous studies had demonstrated that HL is crucial for reverse cholesterol transport and affects the metabolism, composition, and level of several lipoproteins. In current study, we investigated the association of LIPC (Lipase C, Hepatic Type) variants with circulating and urinary biomarker levels by using subgroup and mediation analyses. METHODS: A total of 572 participants from Taiwan were genotyped for three LIPC single nucleotide polymorphisms (SNPs) by using TaqMan assay. Fasting levels of glucose, lipid profile, inflammation markers, urine creatinine and 8-hydroxy deoxyguanosine (8-OHdG) were measured. The chi-square test, 2-sample t test and Analysis of variance (ANOVA) were used to examine differences among variables and genotype frequencies. RESULTS: SNPs rs2043085 and rs1532085 were significantly associated with urinary 8-OHdG levels, whereas all three SNPs were more significantly associated with Triglycerides (TG) or HDL-cholesterol (HDL-C) levels after additional adjustment for HDL-C or TG levels, respectively. Subgroup analyses revealed that the association of the LIPC SNPs with the levels of serum TG, HDL-C, and urinary 8-OHdG were predominantly observed in the men but not in the women. Differential associations of the LIPC SNPs with various lipid levels were observed in participants with different adiposity statuses. Mediation analyses indicated that TG levels acted as a suppressor masking the association of the LIPC genotypes with HDL-C levels, particularly in the men (Sobel test, all P < 0.01). CONCLUSION: Our data revealed that interaction and suppression effects mediated the pleiotropic association of the LIPC variants. The effects of the LIPC SNPs depended on sex, adiposity status, and TG levels. Thus, our findings can provide a method for identifying high-risk populations of cardiovascular diseases for clinical diagnosis.

Bacteria-Derived Recombinant Human ANGPTL8/Betatrophin Significantly Increases the Level of Triglyceride.

ANGPTL8/Betatrophin has been implicated in the regulation of both glucose and triglyceride metabolism. However, its role in regulating glucose metabolism by promoting ß cell proliferation remains controversial, and its physiological functions and molecular targets are largely unknown. Hence, it is of great importance to make recombinant protein and test its effects on ß cell mass directly. In this study, the mature form gene of human ANGPTL8/betatrophin was obtained through chemical synthesis on to the vector pUCE, and the fusion protein was expressed in the Transetta (DE3)/pEASY-E2-betatrophin strain. The inclusion bodies were solubilized in urea and purified by Ni-NTA affinity chromatography. The yield of purified ANGPTL8/betatrophin was approximately 20 mg per liter of culture medium. In vitro studies revealed that the recombinant ANGPTL8/betatrophin had no proliferation effect on MIN6 cells but promoted TG levels in HepG2 cells. This method to generate bioactive ANGPTL8/betatrophin is a simple, practical and user-friendly protocol.

Dissection of Complex, Fitness-Related Traits in Multiple Drosophila Mapping Populations Offers Insight into the Genetic Control of Stress Resistance.

We leverage two complementary Drosophila melanogaster mapping panels to genetically dissect starvation resistance-an important fitness trait. Using >1600 genotypes from the multiparental Drosophila Synthetic Population Resource (DSPR), we map numerous starvation stress QTL that collectively explain a substantial fraction of trait heritability. Mapped QTL effects allowed us to estimate DSPR founder phenotypes, predictions that were correlated with the actual phenotypes of these lines. We observe a modest phenotypic correlation between starvation resistance and triglyceride level, traits that have been linked in previous studies. However, overlap among QTL identified for each trait is low. Since we also show that DSPR strains with extreme starvation phenotypes differ in desiccation resistance and activity level, our data imply multiple physiological mechanisms contribute to starvation variability. We additionally exploited the Drosophila Genetic Reference Panel (DGRP) to identify sequence variants associated with starvation resistance. Consistent with prior work these sites rarely fall within QTL intervals mapped in the DSPR. We were offered a unique opportunity to directly compare association mapping results across laboratories since two other groups previously measured starvation resistance in the DGRP. We found strong phenotypic correlations among studies, but extremely low overlap in the sets of genomewide significant sites. Despite this, our analyses revealed that the most highly associated variants from each study typically showed the same additive effect sign in independent studies, in contrast to otherwise equivalent sets of random variants. This consistency provides evidence for reproducible trait-associated sites in a widely used mapping panel, and highlights the polygenic nature of starvation resistance.

LIPC variants as genetic determinants of adiposity status, visceral adiposity indicators, and triglyceride-glucose (TyG) index-related parameters mediated by serum triglyceride levels.

BACKGROUND: Visceral adiposity indicators and the product of triglyceride and fasting plasma glucose (TyG) index-related parameters are effective surrogate markers for insulin resistance (IR) and are predictors of metabolic syndrome and diabetes mellitus. However, their genetic determinants have not been previously reported. Pleiotropic associations of LIPC variants have been observed in lipid profiles and atherosclerotic cardiovascular diseases. We aimed to investigate LIPC polymorphisms as the genetic determinants of adiposity status, visceral adiposity indicators and TyG index-related parameters. METHODS: A total of 592 participants from Taiwan were genotyped for three LIPC single nucleotide polymorphisms (SNPs). RESULTS: The LIPC SNPs rs2043085 and rs1532085 were significantly associated with body mass index (BMI), waist circumference (WC), lipid accumulation product, visceral adiposity index, and TyG index-related parameters [including the TyG index, TyG with adiposity status (TyG-BMI), and TyG-WC index], whereas the rs1800588 SNP was only significantly associated with the TyG index. The associations became nonsignificant after further adjustment for serum TG levels. No significant association was observed between any the studied LIPC SNPs and IR status. CONCLUSION: Our data revealed a pleiotropic association between the LIPC variants and visceral adiposity indicators and TyG index-related parameters, which are mediated by serum TG levels.

Study of association between beverage consumption pattern and lipid profile in shift workers.

AIMS: The circadian system influences on health and metabolic function that can cause raising some risk factor of metabolic syndrome. Few studies have examined data that incorporate the full complexity of daily beverage intake pattern on lipid profiles. The purpose of this study was to investigate relation between daily water and beverage intake of adults working in day or shift work and lipid profile. MATERIALS AND METHODS: Total beverages intake was estimated in shift and administrative staff of Ahvaz International Airport, Iran. Forty five male, aged 25-55 years, attending this institute were invited to participate in this study. They completed a three-day food records and all participants were measured plasma lipid profiles. RESULTS AND CONCLUSION: Forty one of participants completed all aspects of the study. Two clusters were emerged, labeled descriptively as Conventional including "high Sugar-sweetened drinkers" and "low sugar drinkers". The highest intake of water was in cluster 1 (1170.9ml/day) even this amount is much less than the daily recommended amounts. There were significant differences in triglyceride levels among day and night shift workers. According to the results, there is inadequacy of water and high sugar beverage intake among the shift workers which it is a potential risk of some related chronic diseases such as metabolic syndrome with high triglyceride level in the future.

Association of early maternal hypertriglyceridemia with pregnancy-induced hypertension.

BACKGROUND: Hypertensive diseases are directly responsible for 24 % of maternal deaths in India. A screening method is yet to be discovered to reduce the morbidity and mortality related to it. Serum triglyceride (TG) levels are reported to increase in hypertensive pregnant women. AIM: To predict pregnancy-induced hypertension (PIH) by serum triglyceride values. METHOD: This study is a prospective cohort study that was conducted over three hundred normotensive, primigravida women with singleton pregnancy at 14-20 weeks of gestation. These were divided into two groups on the basis of their TG concentration estimated at 14-20 weeks of gestation. The pregnancy was then followed till delivery and, signs and symptoms of PIH were noted in both the groups. RESULTS: Out of 300 women, 210 women completed the study. Fifty-nine women developed PIH and 151 women remained normotensive. Among 59 women, 45 women had raised TG values i.e., ≥160 mg/dL and 14 women were with normal TG levels i.e., <160 mg/dL. A significant positive correlation was found between serum TG concentration and systolic and diastolic blood pressure. It was observed that a cutoff of 162.50 mg/dL for TG could reliably predict PIH with sensitivity of 76 % and specificity of 85 %. Also, the mothers with hypertriglyceridemia were found to be at higher risk of developing early-onset PIH. CONCLUSION: Our study supports the evidence that early pregnancy hypertriglyceridemia is associated with an increased risk of PIH.

Effects of aerobic exercise during hemodialysis on physical functional performance and depression.

Previous studies have concluded that exercise training is beneficial to patients on hemodialysis (HD). Results, however, have shown that differences in the type, intensity, and frequency of physical exercise lead to variability in its effects on physical functional performance and depression. Further research is thus warranted. Our aim was to evaluate the effects of aerobic exercise on physical functional performance and depression during HD. Using a pretest-posttest control group design, we recruited HD patients and nonrandomly assigned them to an exercise group (n = 13) that completed a 12-week aerobic exercise program during HD or a control group (n = 11) that did no exercise during HD. The primary outcome measures were physical functional performance, as evaluated by the 6-min walk test and the sit-to-stand test, and depression, as evaluated by the Beck Depression Inventory II. The secondary outcome measures were albumin and triglyceride levels and hematocrit. Results revealed significant between-group differences in physical functional performance and depression but not in albumin level, hematocrit, or triglyceride level. Findings suggest that exercise may play a critical role in physical functional performance and may decrease depression. Exercise should be encouraged and performed during HD in HD centers.

Effects of Benincasa hispida Seeds Intake on Blood Glucose and Lipid Levels in Streptozotocin Induced Diabetic Rats

This study was designed to examine the effects of diets containing different levels of seeds of Benincasa hispida (wax gourd) on plasma glucose, insulin levels and lipid profiles in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divide into 4 groups: normal, STZ-control, two experimental groups. Normal and STZ-control groups were fed an AIN-93 diet and 2 experimental groups were fed a modified diet containing 2.5% and 5.0% of wax gourd seed powder for 4 weeks. The weight gain and feed efficiency ratio in 5.0% seed groups were higher than in STZ-control group. A significant lowering effects of plasma glucose levels were observed in the wax gourd seed 2.5% and 5.0 groups. The plasma insulin level did not differ after treatment with wax gourd seed in experimental rats. The intake of 2.5% wax gourd seed did not result in significant change in plasma cholesterol levels compared to diabetic control group. The intake of 2.5% wax gourd seeds had normalized the increased levels of plasma triglyceride and free fatty acids after 4 weeks. In 5% wax gourd seed group, cholesterol, triglyceride and free fatty acid levels were elevated compared to 2.5% wax gourd seed group. The results of the present study indicate that 2.5% wax gourd seed group would be more effective to control the diabetes than 5% wax gourd seed group.

Triglyceride level changes and potential mechanism on alcoholic fatty liver cell model induced in vitro:with or without diammonium glycyrrhizinate / 重庆医科大学学报

Objective:To study the triglyceride level changes with or without Diammounium Glycyrrhizinate(DIG)and the potential mechanism on alcoholic fatty liver cell model induced in vitro.Methods:MTT assay was used to screen the optimal concentration of ethanol and DIG injection.Ultra-microstructure was observed under transmission electron microscope.Intracellular triglyceride concentration was measured by hol-automatic biochemistry.Expressions of peroxisome proliferator-activated receptor-gamma (PPAR?),sterol regulatory element binding protein-1(SREBP-1)and SREBP cleavage activating protein(SCAP)were determined by immunocyto-chemistry(ICC).Results:1.The screened optimal DIG concentration was 2.273?g/ml.2.Masses of lipid droplets in cytoplasm were observed under transmission electron microscope.3.Hol-automatic biochemistry measured intracellular triglyceride concentration to be(1.84?0.16)mmol/L and(1.05?0.12)mmol/L respectively in Ld30 group and DIG group,and the difference was statistically significant(P
