[Objective] The study was conducted to investigate the effect of micronized fenofibrate on acute insulin response in the subjects with impaired glucose metabolism and hypertriglyceridemia. [Methods] Fifty-three subjects were randomly (2:1 ratio) allocated to fenofibrate group (n=36, including IFG 3 cases, IGT 19 cases, IFG/IGT 6 cases, T2DM 8 cases) or control group (n = 17, including IFG 1 case, IGT 9 cases, IFG/IGT 4 cases, T2DM 3 cases) without any intervention for 3 months. Fasting blood samples were collected for measuring fasting plasma glucose (FPG), free fatty acids (FFA), and lipid profile. IVGTTs were carried out with measurement of plasma insulin before and after treatment. Acute insulin response (AIR), the maximum insulin concentrations (C_(INS,MAX)) to fasting insulin (FINS) ratio (C_(INS,MAX)/FINS) and values of the maximum insulin concentrations increment (△C_(INS)) during IVGTT were calculated as indexes of first-phase insulin secretion. HOMA insulin resistance index (HOMA IR) was used for assessing insulin resistance. [Results] After 3-month treatment, the lipid profile was evidently improved in fenofibrate group. Levels of trigiyceridemia (TG), low-density lipoprotein cholesterol and FFA were significantly reduced and high-density lipoprotein cholesterol increased significantly. Waist circumference was also significantly declined. No change of above indicators was found in control group. In fenofibrate group, C_(INS,MAX)/FINS and △C_(INS) were significantly increased (median 8.4 pmol/L vs. 5.3 pmol/L, 808±473 pmol/L vs. 660±472 pmol/L, both P<0.0001), along with great improvement of AIR (5 585±3 441 pmol·L~(-1)·min~(-1) vs. 4 444±3 642 pmol·L~(-1)·min~(-1), P<0.0001). The level of FINS and HOMA IR was also markedly reduced (108±65 pmol/L vs. 166±115 pmol/L, P = 0.002; 3.8±2.3 vs. 6.0±4.2, P = 0.001). In contrast, there were modest declining in acute insulin response (AIR: 4 313~1 943 pmol·L~(-1)·min~(-1) vs. 5 362±2 861 pmol·L~(-1).min~(-1); C_(INS,MAX)/FINS: median 4.6 vs. 7.0, P= 0.01; △C_(INS): 641±286 pmol/L, vs. 720±321 pmol/L, P= 0.003 9) and increasing HOMA IR (7.8±4.2 vs. 5.6±3.2, P<0.000 1) in control group after 3-month follow-up. The improvement of AIR was correlated with the decreasing of plasma FFA and TG (r=0.41, 0.36, P = 0.002, 0.014), but no correlation with the changing of FPG and HOMA IR. [Conclusions] These results indicated that sbort-term lipid-lowering treatment with fenofibrate evidently improved acute insulin response and alleviated insulin resistance in subjects with impaired glucose metabolism and hypertriglyceridemia. Moreover, the improvement of insulin secretion capacity may be mainly due to the relieving of iipotoxity resulting from finofibrate.

Thirty six patients with hypertriglyceridemia and impaired glucose regulation or newly diagnosed type 2 diabetes, whose fasting plasma glucose was ≤8.0 mmol/L, were treated by fenofibrate for 3 months. Lipid profile, insulin during intravenous glucose tolerance test and oral glucose tolerance test ( including glucose) were measured before and after treatment After treatment, lipid profile was significantly improved. Insulinogenic index (△I30/△G30) and acute insulin response were significantly increased (98. 9vs. 129. 2, 3558.9 vs. 4783. 3 pmol · L - 1 · min - 1, respectively, P < 0. 05 ). Fasting insulin and insulin resistant index in homeostasis model assessment ( HOMA IR) decreased ( 128. 6 vs. 84. 8 pmol/L, 4. 8 vs.3.0, respectively, P <0. 05 ). The improvement of insulin secretory function was more significant in patients with higher triglyceride (TG > 3. 3 mmol/L). These results indicate that short-term lipid-lowering treatment with fenofibrate can improve β-cell function and insulin resistance. Patients with higher triglyceride are likely to achieve more benefit from lipid-lowering treatment.

ObjectiveFrom the changes of expression of cold-inducible RNA-binding protein (CIRP) in rats with traumatic brain injury under mild hypothermia treatment with Shenfu decoction as a subsidiary, to speculate the mechanism of protective effect of the decoction on the injury.Methods Ninety Sprague-Dawley (SD) rats were divided into three groups by random number table: non-transfection control group, adenovirus mediated immune flourescent reverse transcription virus group (blank AD5-GFP transfection group) and adenovirus mediated immune flourescent reverse transcription virus carrying CIRP silent expression gene group (AD5-GFP-CIRP-SiRNA transfection group), 30 rats in each groups. Then, each group was subdivided into three subgroups: model group, traditional Chinese medicine (TCM) low and high dose groups, 10 rats in each subgroup. After the mild hypothermia treatment for 48 hours, in the TCM low dose group and high dose group, a dose of TCM 1 mL/kg and 5 mL/kg was injected via a tail vein into the rat respectively, while in the model group, 1 mL/kg normal saline was injected into the same vein, once a day for consecutive 2 days in all the groups. Before modeling in the blank AD5-GFP transfection group and AD5-GFP-CIRP-SiRNA transfection group, virus transfection models were reproduced at first by one-time intrathecal injection of 0.1 mL AD5-GFP and 0.1 mL (1×1010 pfu/mL) AD5-GFP-CIRP-SiRNA virus vector respectively, and in model group, 0.1 mL normal saline was given. The rat cortex, hippocampus and hypothalamus part were collected, the brain cell apoptosis was detected by transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL), the CIRP mRNA expression in the cortex, hippocampus and hypothalamus part was measured by reverse transcription-polymerase chain reaction (RT-PCR), the protein expressions of rat sarcoma protein Raf, Ras, extracellular signal-regulated kinase (ERK), phosphorylation ERK (p-ERK), mitogen activated protein kinase (MEK), p-MEK were determined by Western Blot.Results The brain tissue cell apoptosis indexes (AI) in the cortex, hippocampus and hypothalamus part in TCM low, high dose group of non-transfection control and blank AD5-GFP transfection group were lower than those in model group, and the expressions of CIRP mRNA were higher than those in model group, there were no significant differences in AI and CIRP mRNA in the cortex, hippocampus and hypothalamus between model, TCM low and high dose groups of AD5-GFP-CIRP-SiRNA transfection group, but AI was significantly higher and CIRP mRNA was significantly lower than that in corresponding subgroups of AD5-GFP transfection control group and blank AD5-GFP transfection group. Western Blot detection showed that: Raf/Ras, p-MEK/MEK protein expressions revealed no statistical significant differences in different parts of each group (allP > 0.05), the p-ERK/ERK protein expression in the cortex, hippocampus, and hypothalamus part was significantly lower in TCM low and high dose group than that in the model group of non-transfection control group and blank AD5-GFP transfection group, the degree of descent in the TCM high dose group being more significant (the cortex: non-transfection control group was 7.2±1.0 vs. 15.3±1.8, AD5-GFP transfection group was 8.1±0.7 vs. 16.2±1.5; hippocampus part: non-transfection control group was 6.6±0.8 vs. 14.7±2.0, AD5-GFP transfection group was 6.8±1.0 vs. 14.9±1.3; hypothalamus part: non-transfection control group was 9.4±1.1 vs. 12.7±1.7, AD5-GFP transfection group was 10.6±1.3 vs. 9.4±1.1, allP < 0.05). There were no significant statistical differences in p-ERK/ERK protein expression in above brain parts between AD5-GFP-CIRP-SiRNA transfection subgroups (allP > 0.05).Conclusions The Shenfu decoction used in rats with brain trauma under treatment of mild hypothermia is possibly by promoting CIRP over-expression, lowering ERK expression and inhibiting the initiation of signal transduction of the secondary transcription factor phosphorylation, thereby the neural cell apoptosis is decreased and play a subsidiary role of anti-apoptosis of mild hypothermia.

One hundred and forty-five patients with primary aldosteronism (PA) admitted from 2006 to 2013 were enrolled in the study. The diagnosis of PA was confirmed by upright furosemide test and all patients met the following criteria: ① round-or oval-shaped lesion of low density with diameter>1 cm in one adrenal gland shown in contrast CT scan; ② no lesion or abnormality in contralateral adrenal gland; ③serum potassium level<3.5 mmol/L. Of 145 patients, 106 underwent total adrenalectomy, 36 partial adrenalectomy and 3 tumor enucleation. Serum potassium was (2.75±0.55) mmol/L before and (4.03±0.46) after surgery. Potassium was normalized after treatment in 141 cases (97.2%) with correction or improvement in hypertension; 4 patients (2.8%) remained hypokalemic and received spironolactone. Patients with normalized potassium were followed up for a medium period of 74 months (22—103 months), of whom 32 (22.7%) dropped off; the remaining 109 (77.3%) patients did not have hypokalemia. Multivariate linear correlation analysis showed that serum potassium level was negatively correlated with tumor diameter (r=?0.273,95% CI:?0.086—?0.564, P=0.026) and basal serum aldosterone level (r=?0.261,95% CI:?0.047— ?0.514, P=0.036). In PA patients with unilateral adrenal macroadenoma and hypokalemia, satisfactory surgical resolution can be achieved without adrenal venous sampling in majority of patients.
