Relationship between hypoadiponectinemia and hypertension in young individuals with normal renal function: Hanzhong adolescent hypertension study / 西安交通大学学报(医学版)

【Objective】 To explore the relationship between plasma adiponectin levels and hypertension based on the Hanzhong adolescent hypertension cohort. 【Methods】 A total of 361 young individuals with normal renal function， aged 32 to 41 years old， were taken as the research subjects. We collected or measured data including general characteristics， blood pressure （BP）， height， weight， pulse rate， and biochemistry indexes such as fasting glucose， blood lipid and plasma hs-CRP. The concentration of plasma adiponectin was determined by ELISA method. Binary logistic regression was performed to analyze the relationship between plasma adiponectin and hypertension. 【Results】 The plasma adiponectin level in patients with hypertension was significantly lower than that in normotensive patients ［3.56 （2.57-5.02）） μg/mL vs. 4.82 （3.19-6.89） μg/mL， P=0.012］. Partial correlation analysis showed a weak correlation of plasma adiponectin level with systolic BP and diastolic BP （r=-0.155， P=0.003 and r=-0.144， P=0.006）. Binary logistic regression analysis showed that after adjusting for confounding factors such as age， BMI， and high-sensitivity C-reactive protein， the risk of hypertension was 2.46 times higher in patients with plasma adiponectin in the lowest gender-specific tertile than those in the highest tertile （OR=2.46， 95% CI: 1.22-4.99）. 【Conclusion】 Hypoaponectinemia is an independent risk factor for hypertension in young individuals with normal renal function.

Effects of liraglutide on fibroblast growth factor-21 and its receptors in insulin-resistant mice with hypoadiponectinemia / 中华内分泌代谢杂志

The effects of liraglutide on glucose and lipid metabolism, fibroblast growth factor-21 ( FGF-21 )and its receptors (FGFR) in APoE-/-mice with hypoadiponectinemia were investigated.Hypoadiponectinemia facilitated disturbance in glucose and lipid metabolism and insulin resistance. Compared with the control mice, FGF21 mRNA and protein expressions of liver and adipose tissues as well as plasma FGF-21 level were significantly increased in ApoE-/-mice with hypoadiponectinemia, along with lowered expressions of FGFR1 and β-klotho mRNA in adipose tissues, and expressions of FGFR1-3 and β-klotho mRNA in liver. Liraglutide administration improved glucose and lipid metabolism and insulin resistance, and partially reversed the changes of FGF-21 and its receptors induced by hypoadiponectinemia.
