OBJECTIVETo investigate the fat decreasing effects of fenofibrate on alcoholic fatty liver and drug-induced fatty liver in rats.
METHODSAlcoholic fatty liver and drug-induced fatty liver rats models were established. The two kinds of rats with fatty liver were seperatedly divided into fenofibrate treatment group (80 mg/kg daily) and control group without treatment. Rats were killed after four weeks, then the levels of serum triglycerides (TG), total cholesterol (TC), high density lipoprotein (HDL) and malondialdehyde (MDA), hepatic lipase (HL), lipoprotein lipase (LPL) both in serum and liver tissue were measured according to the Test Kits. Histopathological changes in liver was dyed with HE and observed under light microscope.
RESULTSAfter treatment by fenofibrate, in the serum of rats with alcoholic fatty liver, the level of TG decreased significantly (1.07 mmol/L 0.06 mmol/L vs 1.56 mmol/L 0.29 mmol/L, t=5.115, p<0.001), while the level of TC had no alteration. The levels of MDA both in serum and liver tissue decreased (1.10 nmol/L 0.22 nmol/L vs 1.26 nmol/L 0.21 nmol/L, t=0.592, p<0.05; 5.92 nmol/g 1.24 nmol/g vs 7.42 nmol/g 1.22 nmol/g, t=3.477, p<0.05, respectively), while the levels of HL, LPL in serum and liver tissue increased significantly (Serum: 0.053muEq/ml/h 0.006muEq/ml/h vs 0.037 muEq/ml/h 0.006muEq/ml/h, t=-5.086, p<0.001; 0.018 muEq/ml/h 0.004 muEq/ml/h vs 0.014muEq/ml/h 0.004muEq/ml/h, t=-2.485, p<0.05. Liver tissue: 0.075muEq/ml/h 0.010muEq/ml/h vs 0.065muEq/ml/h 0.007muEq/ml/h, t=-2.437, p<0.05; 0.022 muEq/ml/h 0.014 muEq/ml/h vs 0.008 muEq/ml/h 0.002 muEq/ml/h, t=-2.876, p<0.05). Fat content in liver decreased (26.01 mg/g 1.69 mg/g vs 71.45 mg/g 2.66 mg/g, t=-43.224, p<0.001). The pathological changes of liver in fenofibrate-treated rats with alcoholic fatty liver were improved. For the drug-induced fatty liver rats, fenofibrate treatment group had no difference from the untreated control group.
CONCLUSIONFenofibrate can significantly decrease the fat content in liver tissue of rats with alcoholic fatty liver, as well as ameliorating liver pathological changes. But fenofibrate has no effect on drug-induced fatty liver.

OBJECTIVETo investigate the prevalence, etiology and clinical characteristics of adrenal lesions detected by abdominal computed tomography (CT).
METHODSThis retrospective study was conducted in patients with adrenal lesions detected by abdominal CT examinations in Nanfang Hospital between July, 2014 and June, 2015. The clinical data of the patients were collected for analysis of the demographics, comorbidities, imaging characteristics, biochemical profiles, clinical diagnosis and intervention.
RESULTSA total of 939 patients with adrenal lesions were identified from 19 004 patients undergoing abdominal CT scan over the defined period. The mean age of the patients was 53.2 years and 560 of the patients were male. Among the total cases with adrenal lesions, the percentages of cases with adrenal masses tended to increase progressively with age. Endocrine studies were done in 270 of the total patients, which identified non-functioning masses in 38.9%, primary aldosteronism in 16.3%, Cushing's syndrome in 4.1%, subclinical Cushing's syndrome in 7.0%, and pheochromocytomas in 7.0% of the cases. Adrenal incidentalomas was detected in 191 patients, with a detection rate of 1.0% among the overall patients undergoing abdominal CT scans. Imaging study detected adenomas (70.3%), cortical carcinomas (2.4%), and metastases (0.5%). Of 191 patients with adrenal incidentalomas, only 76 (39.8%) underwent endocrine evaluation, including 34 with nonfunctioning adrenal masses, 17 with pheochromocytoma, 7 with primary aldosteronism, and 5 with subclinical Cushing's syndrome.
CONCLUSIONs The overall detection rates of adrenal lesions and adrenal incidentalomas by abdominal CT were 4.9% and 1.0%, respectively, in our cohort of patients undergoing the examination over the defined period. Although most of the lesions were benign and nonfunctioning, malignant and functional lesions were also detected. As many as 60% of the patients with adrenal incidentalomas did not have hormonal testing. Clinicians need to have greater awareness of adrenal incidentalomas and standard protocol for its management should be established.

OBJECTIVETo investigate the protective effect of exendin-4 against diabetic cardiomyopathy in mice and explore the underlying mechanism.
METHODSC57BL/6J mice were randomly divided into normal control group with normal diet and diabetic group with high-fat diet for 4 weeks before streptozotocin injection. The successfully established diabetic mouse models were divided into diabetic group with exendin-4 treatment and diabetic control group for daily treatment with intraperitoneal injection of 1 nmol/kg exendin-4 and saline of equivalent volume for 8 weeks, respectively. The physiological parameters such as blood glucose and body weight were recorded. RT-PCR was used to examine the transcription levels of genes related with myocardial hypertrophy and fibrosis and the genes related with mitochondrial functions including PGC1α, NRF and CytoC. The expressions of oxidative stress markers and Sirt1/PGC1 proteins were measured using Western blotting. and HE staining was used to observe the myocardial structural changes in the mice.
RESULTSCompared with the normal control mice, the mice in diabetic control group showed significantly increased blood glucose and blood lipid levels (P<0.001), which were obviously improved by Exendin-4 treatment. The expressions of ANP, BNP, TGFβ1, CytoC1 and NOX1 were significantly increased (P<0.05) while Sirt1, PGC1α, NRF and SOD1 expression were markedly decreased in the myocardial tissue of the diabetic mice (P<0.05). Exendin-4 treatment resulted in obviously reduced expressions of ANP, BNP, TGFβ1, CytoC1 and NOX1 (P<0.05) and increased expressions of Sirt1, PGC1α, NRF and SOD1 (P<0.05) in the diabetic mice.
CONCLUSIONSExendin-4 protects against myocardial injury in diabetic mice by improving mitochondrial function and inhibiting oxidative stress through the Sirt1/PGC1α signaling pathway.

OBJECTIVETo investigate the expressions of inflammation- and fibrosis-related genes in perinephric and subcutaneous adipose tissues in patients with adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome.
METHODSThe perinephric and subcutaneous adipose tissues adipose tissues were obtained from 8 patients with ACTH-independent Cushing's syndrome undergoing laparoscopic retroperitoneal adrenalectomy. Real-time PCR was used to detect the mRNA expression levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), matrix metallopeptidase 2 (MMP-2), TIMP metallopeptidase inhibitor 1 (TIMP-1), early growth response 1 (EGR1), CCAAT/enhancer binding protein β(CEBPβ), uncoupling protein 1(UCP-1), PPARγ coactivator 1 alpha (PGC1α) and cell death-inducing DFFA-like effector a (CIDEA).
RESULTSThe mRNA level of CIDEA was significantly higher in the perinephric adipose tissue (peri-N) than in the subcutaneous adipose tissue (subQ) (P<0.05). The expressions of CEBPβ, UCP-1, and PGC1α mRNA in the peri-N were similar with those in the subQ. The expressions of IL-6, TIMP1 and EGR1 mRNA in the subQ were significantly higher than those in the peri-N (P<0.05). No significant difference in TNF-α and MMP-2 mRNA levels was found between peri-N and subQ.
CONCLUSIONThe expression levels of the inflammation- and fibrosis-related genes are higher in the subQ than in the peri-N of patients with ACTH-independent Cushing's syndrome, suggesting that chronic exposure to endogenous hypercortisolism may cause adipose tissue dysfunction.
