Alzheimer's disease (AD) is the most common type of dementia, and promptly diagnosis of AD is crucial for delaying the development of disease and improving patient quality of life. However, AD detection, particularly in the early stages, remains a substantial challenge due to the lack of specific biomarkers. The present study was undertaken to identify and validate the potential of circulating miRNAs as novel biomarkers for AD. Solexa sequencing was employed to screen the expression profile of serum miRNAs in AD and controls. RT-qPCR was used to confirm the altered miRNAs at the individual level. Moreover, candidate miRNAs were examined in the serum samples of patients with mild cognitive impairment (MCI) and vascular dementia (VD). The results showed that four miRNAs (miR-31, miR-93, miR-143, and miR-146a) were markedly decreased in AD patients' serum compared with controls. Receiver operating characteristic curve analysis demonstrated that this panel of four miRNAs could be used as potential biomarker for AD. Furthermore, miR-93, and miR-146a were significantly elevated in MCI compared with controls, and the panel of miR-31, miR-93 and miR-146a can be used to discriminate AD from VD. We established a panel of four serum miRNAs as a novel noninvasive biomarker for AD diagnosis. © 2015 Hui Dong et al. Source

Objective: Adiponectin receptor 1 (encoded by ADIPOR1) is one of the major adiponectin receptors, and plays an important role in glucose and lipid metabolism. However, few studies have reported simultaneous associations between ADIPOR1 variants and type 2 diabetes (T2D), coronary artery disease (CAD) and T2D with CAD. Based on the "common soil" hypothesis, we investigated whether ADIPOR1 polymorphisms contributed to the etiology of T2D, CAD, or T2D with CAD in a Northern Han Chinese population. Methods: Our multi-disease comparison study enrolled 657 subjects, including 165 with T2D, 173 with CAD, 174 with both T2D and CAD (T2D+CAD), and 145 local healthy controls. Six ADIPOR1 single nucleotide polymorphisms (SNPs) were genotyped and their association with disease risk was analyzed. Results: Multi-case-control comparison identified two ADIPOR1 variants: rs3737884-G, which was simultaneously associated with an increased risk of T2D, CAD, and T2D+CAD (P-value range, 9.80×10-5-6.30×10-4; odds ratio (OR) range: 1.96-2.42) and 16850797-C, which was separately associated with T2D and T2D+CAD (P-value range: 0.007-0.014; OR range: 1.71-1.77). The risk genotypes of both rs3737884 and 16850797 were consistently associated with common metabolic phenotypes in all three diseases (P-value range: 4.81×10 -42-0.001). We observed an increase in the genetic dose-dependent cumulative risk with increasing risk allele numbers in T2D, CAD and T2D+CAD (Ptrend from 1.35×10-5-0.002). Conclusions: Our results suggest that ADIPOR1 risk polymorphisms are a strong candidate for the "common soil" hypothesis and could partially contribute to disease susceptibility to T2D, CAD, and T2D with CAD in the Northern Han Chinese population. © 2014 Jin et al.

Objective: To observe the effect of combined acupuncture and medication for hypertension due to type 2 diabetes and plasma Neuropeptide Y (NPY). Methods: Sixty cases with hypertension due to type 2 diabetes were randomized into two groups. Thirty cases in the treatment group were treated with acupuncture and oral extended release nifedipine tablets, while 30 cases in the control group were treated with oral extended release nifedipine tablets alone. After 15 d of treatment, the blood pressure and NPY contents in two groups were observed. Results: The blood pressure and NPY contents in the two groups were remarkably reduced (P<0.01) and the effect in the treatment group was superior to the control group (P<0.01). Conclusion: Combined acupuncture and medication can significantly reduce blood pressure and the NPY contents. © 2010 Shanghai Research Institute of Acupuncture and Meridian and Springer-Verlag Berlin Heidelberg.

The knowledge of dyslipidemia and its genetic contributors in oldest-old subjects is limited; in addition, the majority of oldest-old subjects are females. Evidence has accumulated that multiple genetic factors play important roles in determining susceptibility to dyslipidemia and extended life span. Cholesterol ester transfer protein (CETP) and apolipoprotein E (APOE) are two plausible candidate genes for human longevity owing to their functionally related modulation of circulating lipid homeostasis; however, few studies have considered their interplay. In this study, we analyzed the distribution of CETP*V (rs5882) and APOE*4 (rs429358 and rs7412) in 372 oldest-old Chinese women (aged 80-109) and 340 controls (aged 20-58). In addition to replicating the association of longevity, our main goal was to evaluate the contribution of CETP*V, APOE*4 and CETP*. APOE interaction to the risk of dyslipidemia. Only APOE*4 conferred a risk against longevity and was associated with high-cholesterol (hTC) and mixed dyslipidemia for oldest-old females. Moreover, CETP*V was found to be associated with hypertriglyceridemia (hTG) independently from APOE*4, age, BMI, alcohol drinking, TC, TG, HDL-c, and LDL-c. The stratification test, multivariable-adjusted logistic regression, and nonparametric MDR analysis all suggested a significant CETP*. APOE interaction associated with hTG. The unadjusted odds for hTG were more than 4-fold in subjects with CETP*V and APOE*4 than those without either (OR=4.36, P<. 0.001). These results provide evidence of strong independent associations between hTG and CETP*V in oldest-old Chinese females, and APOE*4, as an independently non-significant variant, might interact with CETP*V resulting in an increased risk for hTG. © 2014 Elsevier Inc.

Background: Glucose homeostasis is a trait of healthy ageing and is crucial to the elderly, but less consideration has been given to the age composition in most studies involving genetics and hyperglycemia. Methods: Seven variants in FOXO3 were genotyped in three cohorts (n = 2037; LLI, MI-S and MI-N; mean age: 92.5±3.6, 45.9±8.2 and 46.8±10.3, respectively) to compare the contribution of FOXO3 to fasting hyperglycemia (FH) between long-lived individuals (LLI, aged over 90 years) and middle-aged subjects (aged from 35-65 years). Results: A different genetic predisposition of FOXO3 alleles to FH was observed between LLI and both of two middle-aged cohorts. In the LLI cohort, the longevity beneficial alleles of three variants with the haplotype "AGGC" in block 1 were significantly protective to FH, fasting glucose, hemoglobin A1C and HOMA-IR. Notably, combining multifactor dimensionality reduction and logistic regression, we identified a significant 3-factor interaction model (rs2802288, rs2802292 and moderate physical activity) associated with lower FH risk. However, not all of the findings were replicated in the two middle-aged cohorts. Conclusion: Our data provides a novel insight into the inconsistent genetic determinants between middle-aged and LLI subjects. FOXO3 might act as a shared genetic predisposition to hyperglycemia and lifespan. © 2015 Sun et al.
