		                        			To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
 Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
 Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L 
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
 Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.

		                        			BACKGROUND: The prevalence of hypertension reaches 29% in adults over 30 years of age in the Korean population; however, the control rate is merely 44%. The aim of this study was to investigate the associated factors for target blood pressure achievement after triple combination therapy in hypertensive patients. METHODS: From February 2016 to May 2018, 10 family physicians recruited 348 patients, who newly started a triple combination antihypertensive medication. Target blood pressure was defined as a systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) <90 mmHg after 6 months of triple combination therapy. Multivariate logistic regression analyses were performed to analyze the associated factors for target blood pressure achievement. RESULTS: Among the 348 study participants, 317 completed 6 months of treatment. The target achievement rate was 76.3% (242/317). The mean absolute difference and 95% confidence interval (CI) for the SBP and DBP were 10.8 mmHg (8.8 to 12.7) and 6.4 mmHg (5.1 to 7.8), respectively (P<0.05). The odds ratio (OR) for the target blood pressure achievement increased in those with college education or higher (OR, 2.69; 95% CI, 1.22–5.92), those with dyslipidemia (OR, 1.74; 95% CI, 1.01–2.99), and those who were satisfied with the medication (OR, 29.91; 95% CI, 3.70–241.92). CONCLUSIONS: The presence of dyslipidemia and patient's satisfaction with the medication were associated with target blood pressure achievement in our analyses. Our findings suggest the importance of patient's factor in the control of blood pressure.

OBJECTIVETo observe the efficacy of fenofibrate for hepatic steatosis in rats after severe burn.
METHODSTwenty-seven male SD rats were divided into sham injury group, burn group, and burn+ fenofibrate group according to the random number table, with 9 rats in each group. Rats in sham injury group were sham injured on the back by immersing in 37 ℃ warm water for 15 s and then remained without other treatment. Rats in burn group and burn+ fenofibrate group were inflicted with 30% total body surface area full-thickness scald (hereinafter referred to as burn) on the back by immersing in 98 ℃ hot water for 15 s, and then they were intraperitoneally injected with lactated Ringer's solution at post injury hour (PIH) 1. From PIH 24 to post injury day (PID) 8, rats in burn+ fenofibrate group were treated with fenofibrate in the dose of 80 mg·kg(-1)·d(-1), while those in burn group were treated with equivalent volume of saline. (1) Three rats of each group were respectively selected on PID 4, 6, and 8 for the collection of inferior vena caval blood samples. Serum content of total cholesterol (TC), triglyceride (TG), free fatty acid (FFA), high density lipoprotein (HDL), and low density lipoprotein (LDL) was determined with fully automatic biochemical analyzer. Body mass of each rat was measured immediately after blood sampling, and then rats were sacrificed to collect liver tissue for weighing wet mass. The ratio of wet mass of liver tissue to body mass (liver index) was calculated. Meanwhile, gross observation of liver was performed. (2) One liver tissue sample was harvested from each rat at each time point to observe histopathologic changes with HE staining. One liver tissue slice of each rat at each time point was collected to evaluate degree of hepatic steatosis, and the number of rats in each group in each grade of hepatic steatosis was recorded. Measurement data were processed with analysis of variance of factorial design and SNK test, and enumeration data were processed with Kruskal-Wallis test and Nemenyi test.
RESULTS(1) The content of TC, TG, FFA, and HDL of rats in burn group on PID 4 was obviously different from that in sham injury group (with P values below 0.05). Compared with that in burn group, the content of TC, TG, and FFA of rats was significantly decreased (with P values below 0.05), while the content of HDL of rats was not obviously changed in burn+ fenofibrate group on PID 4 (P>0.05). There were no obvious differences in the content of LDL of rats among 3 groups on PID 4 (with P values above 0.05). The content of TC, TG, and HDL of rats in burn group on PID 6 was obviously different from that in sham injury group (with P values below 0.05). Compared with that in burn group, the content of TC and TG of rats was significantly decreased (with P values below 0.05), while the content of HDL of rats was significantly increased in burn+ fenofibrate group on PID 6 (P<0.05). There were no obvious differences in the content of FFA and LDL of rats among 3 groups on PID 6 (with P values above 0.05). The content of TC and HDL of rats in burn group on PID 8 was obviously different from that in sham injury group (with P values below 0.05). Compared with that in burn group, the content of TC of rats was significantly decreased (P<0.05), while the content of HDL of rats was not obviously changed in burn+ fenofibrate group on PID 8 (P>0.05). There were no obvious differences in content of TG, FFA, and LDL of rats among 3 groups on PID 8 (with P values above 0.05). (2) The texture of liver tissue of rats in burn+ fenofibrate group at each time point was tender and soft, without oil or fat on the section, which was close to the gross condition of liver of rats in sham injury group. Dark yellow plaque scattered on the surface of liver tissue of rats in burn group at each time point with oil and fat on the section, which was especially obvious on PID 6. There was no obvious difference in liver index of rats among 3 groups on PID 4 (F=1.63, P>0.05). On PID 6 and 8, the liver indexes of rats in sham injury group, burn group, and burn+ fenofibrate group were 0.0416±0.0016, 0.0533±0.0054, and 0.0370±0.0069; 0.0423±0.0034, 0.0624±0.0005, and 0.0444±0.0042 respectively. The liver indexes of rats in burn group on PID 6 and 8 were significantly higher than those in the other two groups (with P values below 0.05). There were no obvious differences in the liver indexes of rats between burn+ fenofibrate group and sham injury group on PID 6 and 8 (with P values above 0.05). (3) The liver tissue structure of rats in sham injury group was normal at each time point. Hepatic steatosis of rats in burn group at each time point appeared microvesicular and disperse, which was especially obvious on PID 6. Mild hepatic steatosis was observed in rats of burn+ fenofibrate group on PID 4, and then the structure of liver tissue gradually recovered to normal level from PID 6 on. The degree of hepatic steatosis of rats in sham injury group was 0 grade. One rat in I grade, 1 rat in II grade, and 7 rats in III grade were observed in hepatic steatosis of rats in burn group. Three rats in 0 grade, 4 rats in I grade, and 2 rats in II grade were observed in hepatic steatosis of rats in burn+ fenofibrate group. The degree of hepatic steatosis of rats in burn group was more severe than that in the other two groups (with χ(2) values respectively 56.25 and 162.44, P values below 0.05). The degree of hepatic steatosis of rats in burn+ fenofibrate group was more severe than that in sham injury group (χ(2)=27.51, P<0.05).
CONCLUSIONSFenofibrate can ameliorate the dyslipidemia of severely burned rat, and it can alleviate the degree of hepatic steatosis in certain degree.

		                        			Diabetes mellitus is a major chronic disease worldwide, and its prevalence is expected to increase in the near future. Because cardiovascular disease continues to be the leading cause of morbidity and mortality in diabetic patients, it is important to detect and address other risk factors of cardiovascular disease such as hypertension and dyslipidemia. Moreover, presence of diabetes increases the risk of developing hypertension. Despite significant advances in the understanding of the pathophysiology and treatment of hypertension, there are still many debates regarding the management of hypertension, especially in patients with diabetes. The most important unresolved questions are at what blood pressure to initiate drug therapy and the target blood pressure. Recently, the Korean Diabetes Association published "Treatment Guideline for Diabetes 2015." This review will compare major guidelines from other countries and discuss how to determine the target goal for blood pressure control in Korean diabetic patients.

		                        			BACKGROUND/AIMS: This study was designed to evaluate the dose-effect relationship of statins in patients with ischemic congestive heart failure (CHF), since the role of statins in CHF remains unclear. METHODS: The South koreAn Pitavastatin Heart FaIluRE (SAPHIRE) study was designed to randomize patients with ischemic CHF into daily treatments of 10 mg pravastatin or 4 mg pitavastatin. RESULTS: The low density lipoprotein cholesterol level decreased by 30% in the pitavastatin group compared with 12% in the pravastatin (p < 0.05) group. Left ventricular systolic dimensions decreased significantly by 9% in the pitavastatin group and by 5% in the pravastatin group. Left ventricular ejection fraction (EF) improved significantly from 37% to 42% in the pitavastatin group and from 35% to 39% in the pravastatin group. Although the extent of the EF change was greater in the pitavastatin group (16% vs. 11%) than that in the pravastatin group, no significant difference was observed between the groups (p = 0.386). Exercise capacity, evaluated by the 6-min walking test, improved significantly in the pravastatin group (p < 0.001), but no change was observed in the pitavastatin group (p = 0.371). CONCLUSIONS: Very low dose/low potency pravastatin and high dose/high potency pitavastatin had a beneficial effect on cardiac reverse remodeling and improved systolic function in patients with ischemic CHF. However, only pravastatin significantly improved exercise capacity. These findings suggest that lowering cholesterol too much may not be beneficial for patients with CHF.

OBJECTIVETo evaluate the effect of probiotics (bifidobacterium breve and lactobacillus acidophilus) on serum lipid, serum insulin and insulin resistance in high-fat diet (HFD)-induced obese rats.
METHODSFifty male Sprague-Dawley rats were randomly assigned to a control (n=10) and a high fat diet groups (n=40) and were fed with standard diet and HFD respectively. Four weeks later, thirty-six HFD-induced obese rats were randomly administered with normal saline (NS), bifidobacterium breve and lactobacillus acidophilus daily (n=12 each). Four weeks later, body lengths, body weights and abdomen circumference of rats were measured, blood lipid, glucose and insulin levels were measured, and Lee's index and insulin resistance index were calculated.
RESULTSBody weight, abdomen circumference, Lee's index, fasting glucose, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL) in the NS-treated HFD group were significantly higher than the control group (P<0.05). The bifidobacterium breve and lactobacillus acidophilus-treated groups had significantly lower levels of body weight, abdomen circumference, Lee's index, fasting glucose, TC, TG and LDL than the NS-treated HFD group (P<0.05), but the levels of the parameters in the bifidobacterium breve and lactobacillus acidophilus-treated groups were significantly higher than the control group (P<0.05). High density lipoprotein (HDL) and insulin sensitivity index in the NS-treated HFD group were significantly lower than the control group (P<0.05). Bifidobacterium breve and lactobacillus acidophilus treatment dramatically increased HDL levels and insulin sensitivity index compared with the NS-treated HFD group (P<0.05), although the levels of the two parameters did not reach to the levels of the control group. There were significant differences in the levels of fasting insulin, insulin resistance index and insulin secretion index between the bifidobacterium breve and lactobacillus acidophilus groups (P<0.05).
CONCLUSIONSLactobacillus acidophilus and bifidobacterium breve can decrease serum levels of lipid and glucose and improve insulin resistance in obese rats. Bifidobacterium breve seems to be more effective on attenuating insulin resistance than lactobacillus acidophilus.

OBJECTIVETo study whether effect of aspirin plus low-dose diethylstilbestrol is more effective and safer than high diethylstilbestrol dose alone on prevention of ovariectomy-induced osteopenia and dyslipidemia.
METHODSThirty-eight 4-month-old female SD rats were divided into baseline (BAS) group (n=6), sham operation group (n=8) and ovariectomy (OVX) group (n=24). The OVX group was further divided into vehicle treatment group (n=8), diethylstilbestrol (30 μg/kg•d) treatment group (OVX+D30 group, n=8), and aspirin (9 mg/kg•d) plus diethylstilbestrol (10 μg/kg•d) treatment group (OVX+A-D10 group, n=8). Their left tibiae were collected for the bone histomorphometric analysis in undecalcified sections. Left femurs were collected for the bone mineral density measurement.
RESULTSThe body weight and serum cholesterol were increased, while uterine weight and cancellous bone mass were decreased in OVX rats compared with the SHAM group. Cancellous bone mass was significantly increased, while body weight and bone resorption parameters were decreased in both A-D10 and D30 treatment group compared with OVX group. The rats treated with A-D10 showed significantly increased in bone formation parameters and decreased in serum triglyceride compared with the D30-treated rats.
CONCLUSIONAspirin plus low-dose diethylstilbestrol can effectively prevent osteopenia by reducing bone resorption, and is thus a better treatment modality for preventing dyslipidemia than high-dose diethylstilbestrol alone.

		                        			This study aimed to determine whether taurine supplementation improves metabolic disturbances and diabetic complications in an animal model for type 2 diabetes. We investigated whether taurine has therapeutic effects on glucose metabolism, lipid metabolism, and diabetic complications in Otsuka Long-Evans Tokushima fatty (OLETF) rats with long-term duration of diabetes. Fourteen 50-week-old OLETF rats with chronic diabetes were fed a diet supplemented with taurine (2%) or a non-supplemented control diet for 12 weeks. Taurine reduced blood glucose levels over 12 weeks, and improved OGTT outcomes at 6 weeks after taurine supplementation, in OLETF rats. Taurine significantly reduced insulin resistance but did not improve beta-cell function or islet mass. After 12 weeks, taurine significantly decreased serum levels of lipids such as triglyceride, cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol. Taurine significantly reduced serum leptin, but not adiponectin levels. However, taurine had no therapeutic effect on damaged tissues. Taurine ameliorated hyperglycemia and dyslipidemia, at least in part, by improving insulin sensitivity and leptin modulation in OLETF rats with long-term diabetes. Additional study is needed to investigate whether taurine has the same beneficial effects in human diabetic patients.

		                        			The incidence of diabetes mellitus is increasing among companion animals. This disease has similar characteristics in both humans and animals. Diabetes is frequently identified as an independent risk factor for infections associated with increased mortality. In the present study, homozygous diabetic (db/db) mice were infected with Listeria (L.) monocytogenes and then treated with the anti-diabetic drug exendin-4, a glucagon-like peptide 1 analogue. In aged db/db mice, decreased CD11b+ macrophage populations with higher lipid content and lower phagocytic activity were observed. Exendin-4 lowered high lipid levels and enhanced phagocytosis in macrophages from db/db mice infected with L. monocytogenes. Exendin-4 also ameliorated obesity and hyperglycemia, and improved ex vivo bacteria clearance by macrophages in the animals. Liver histology examined during L. monocytogenes infection indicated that abscess formation was much milder in exendin-4-treated db/db mice than in the control animals. Moreover, mechanistic studies demonstrated that expression of ATP binding cassette transporter 1, a sterol transporter, was higher in macrophages isolated from the exendin-4-treated db/db mice. Overall, our results suggest that exendin-4 decreases the risk of infection in diabetic animals by modifying the interaction between intracellular lipids and phagocytic macrophages.
