Association between the Neutrophil-to-lymphocyte Ratio and New-onset Subclinical Macrovascular and Microvascular Diseases in the Chinese Population

Objective The association between neutrophil-to-lymphocyte ratio(NLR)with subclinical macrovascular and microvascular diseases has been less investigated.We sought to examine the association between NLR and new-onset subclinical macrovascular and microvascular abnormalities in the Chinese population.Methods From a community cohort,we included 6,430 adults aged≥40 years without subclinical macrovascular and microvascular diseases at baseline.We measured subclinical macrovascular and microvascular abnormalities separately using the ankle-brachial index(ABI),brachial-ankle pulse wave velocity(baPWV),and albuminuria.Results During a mean follow-up of 4.3 years,110 participants developed incident abnormal ABI,746 participants developed incident elevated baPWV,and 503 participants developed incident albuminuria.Poisson regression analysis indicated that NLR was significantly associated with an increased risk of newonset abnormal ABI,elevated baPWV,and albuminuria.Compared to overweight/obese participants,we found a much stronger association between NLR and subclinical vascular abnormalities in participants with normal weight.Furthermore,we found an interaction between the NLR and body mass index(BMI)on the risk of new-onset abnormal ABI(P for interaction:0.01).Conclusion NLR was associated with subclinical macrovascular and microvascular diseases in the Chinese population.Furthermore,in participants with normal weight,the association between NLR and subclinical vascular abnormalities was much stronger.

Diabetes and cognitive decline:Challenges and future direction

There is growing evidence that diabetes can induce cognitive decline and dementia.It is a slow,progressive cognitive decline that can occur in any age group,but is seen more frequently in older individuals.Symptoms related to cognitive decline are worsened by chronic metabolic syndrome.Animal models are frequently utilized to elucidate the mechanisms of cognitive decline in diabetes and to assess potential drugs for therapy and prevention.This review addresses the common factors and pathophysiology involved in diabetes-related cognitive decline and outlines the various animal models used to study this condition.

Variant rs2237892 of KCNQ1 Is Potentially Associated with Hypertension and Macrovascular Complications in Type 2 Diabetes Mellitus in A Chinese Han Population

KCNQ1 has been identified as a susceptibility gene of type 2 diabetes mellitus （T2DM） in Asian populations through genome-wide association studies. However, studies on the association between gene polymorphism of KCNQ1 and T2DM complications remain unclear. To further ana- lyze the association between different alleles at the single nncleotide polymorphism （SNP） rs2237892 within KCNQ1 and TD2M and its complications, we conducted a case-control study in a Chinese Han population. The C allele of rs2237892 variant contributed to susceptibility to T2DM （odds ratio [OR], 1.45; 95% confidence interval [CI], 1.20 1.75）. Genotypes CT （OR, 1.97; 95% CI, 1.24-3.15） and CC （OR, 2.49; 95% CI, 1.57-3.95） were associated with an increased risk of T2DM. Multivariate regression analysis was performed with adjustment of age, gender, and body mass index. We found that systolic blood pressure （P = 0.015）, prevalence of hypertension （P = 0.037）, and risk of maerovascnlar disease （OR, 2.10; CI, 1.00-4.45） were significantly higher in subjects with the CC genotype than in the combined population with genotype either CT or TT. Therefore, our data support that KCNQ1 might contribute to the higher incidence of patients with T2DM carrying the risk allele C population. is associated with an increased risk for T2DM and hypertension and macrovascular complications in though it needs further to be confirmed in a larger
