Prevalence of SFTSV among Asian House Shrews and Rodents,China, January–August 2013

To evaluate the role of small mammals as hosts of severe fever with thrombocytopenia syndrome virus (SFTSV), we tested serum samples from rodents and shrews in China, collected in 2013. SFTSV antibodies and RNA were detected, suggesting that rodents and shrews might be hosts for SFTSV.     

Relation of genetic polymorphisms in microRNAs with diastolic and systolic function in type 2 diabetes mellitus

Background and aimsType 2 diabetes mellitus (T2DM) has high risk of developing cardiac dysfunction, increasing of either cardiovascular death or hospitalization for heart failure. MicroRNAs (miRNA) affect cardiac function of T2DM. The aim of this study was to investigate the relationships between five miRNA single nucleotide polymorphisms (SNP) and diastolic and systolic function of T2DM.Methods and resultsThree hundred untreated T2DM subjects were included. Each subject underwent SNP genotyping, conventional echocardiography, tissue doppler imaging, and speckle tracking imaging. The effects of miRNA SNPs on diastolic and systolic function were evaluated. The diastolic function of T2DM subjects with miR-133a-1-rs8089787 wild genotype or let-7f-rs10877887 variant genotype was lower than those with miR-133a-1-rs8089787 variant genotype or let-7f-rs10877887 wild genotype, manifesting as higher left atrial volume index, lower mean E′, and higher E/E’ (P < 0.05). There were no significant effects of miR-133a-2-rs13040413, let-7a-1-rs13293512 and miR-27a-rs895819 on the diastolic function of T2DM subjects (P > 0.05). These five miRNA SNPs had no effect on the systolic function of T2DM subjects (P > 0.05).ConclusionsMiRNA-133a-1-rs8089787 and let-7f-rs10877887 were associated with impaired cardiac diastolic function in T2DM. The findings may be a promising therapeutic targets for preventing diastolic dysfunction in T2DM.     

Individual and combined relationship of serum uric acid and alanine aminotransferase on metabolic syndrome in adults in Qingdao,China

Background and aimsAssociations of alanine aminotransferase (ALT) and serum uric acid (SUA) with metabolic syndrome (MetS) remain controversial. We aimed to explore individual and combined effects of ALT and SUA on MetS in community residents.Methods and resultsA population-based cross-sectional survey involving randomly selected Chinese adults aged 35–74 years was conducted in 2009 in Qingdao, China, and 4642 participants were included in the current study. Based on a combination of SUA and ALT levels in the tertile, subjects were grouped into Group 1-9. The individual and combined relations of SUA and ALT to MetS were analyzed by logistic regression models. The prevalence of MetS was 28.50% in males and 22.30% in females. ALT and SUA were independently associated with MetS and ORs (95% CIs) were 1.55 (1.42–1.70) and 1.92 (1.72–2.14), respectively, after adjusting for potential confounders. With the elevation of ALT and SUA levels, the risk of developing MetS increased. Compared to Group 1, ORs (95% CIs) of combined ALT and SUA for MetS were 2.21 (1.70–2.88), 4.02 (3.10–5.21), 2.19 (1.62–2.97), 2.53 (1.91–3.34), 4.69 (3.60–6.12), 1.76 (1.17–2.64), 3.65 (2.63–5.06) and 7.15 (5.41–9.46) in Group 2–9, respectively.ConclusionsALT and SUA were both related to MetS independently. Combined elevation of ALT and SUA levels could increase the risk of MetS and its components than an elevation in SUA and ALT alone. Therefore, measures should be taken to lower SUA and ALT levels to reduce the risk of having MetS.

Family history,waist circumference and risk of ischemic stroke: A prospective cohort study among Chinese adults

Background and aimsThe associations between genetic factors and waist circumference (WC) with stroke risk have been evaluated in Western studies. However, evidence of this association has rarely been reported in the Chinese population. This study aimed to evaluate the association between WC and family history of stroke (FHS) with ischemic stroke (IS) risk among Chinese adults and to further explore the potential interaction of these associations.Methods and resultsThe China Kadoorie Biobank (CKB) study recruited 35,508 participants aged 30–79 years from the Qingdao urban area during 2004–2008. A total of 33,355 participants were included in study. Cox regression analysis was used to estimate the multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the independent and interactional associations between FHS and WC and IS risk. Participants with FHS had a 29% (HR = 1.29, 95% CI: 1.12–1.50) higher IS risk than those without FHS. Participants with excessive WC (85 cm for males and 80 cm for females) had a 78% (HR = 1.78, 95% CI: 1.51–2.10) higher IS risk than those with normal WC. The combined effect of FHS and excessive WC on IS was statistically significant (HR = 2.29, 95% CI: 1.84–2.86). The present study further found statistically significant multiplicative interactions of FHS and WC with IS risk (P _interaction < 0.001).ConclusionThe present study indicated that FHS and WC were significantly associated with an increased risk of IS. The association between FHS and IS was associated with excessive WC.     

Serum Resistin Levels in Adult Patients with Nonalcoholic Fatty Liver Disease: A Systematic Review and Meta-analysis

Background and AimsPrevious studies reported that serum resistin levels were remarkably changed in patients with nonalcoholic fatty liver disease (NAFLD) but the conclusions were inconsistent. The aim of this study was to investigate accurate serum resistin levels in adult patients with NAFLD.MethodsA complete literature research was conducted in the PubMed, Embase, and Cochrane Library databases, and all the available studies up to 7 May 2020 were reviewed. The pooled standardized mean difference (SMD) values were calculated to investigate the serum resistin levels in patients with NAFLD and healthy controls.ResultsA total of 28 studies were included to investigate the serum resistin levels in patients with NAFLD. Patients with NAFLD had higher serum resistin levels than controls (SMD=0.522, 95% confidence interval [CI]: 0.004–1.040, I²=95.9%). Patients with nonalcoholic steatohepatitis (NASH) had lower serum resistin levels than the healthy controls (SMD=−0.44, 95% CI: −0.83–0.55, I²=74.5%). In addition, no significant difference of serum resistin levels was observed between patients with NAFL and healthy controls (SMD=−0.34, 95% CI: −0.91–0.23, I²=79.6%) and between patients with NAFL and NASH (SMD=0.15, 95% CI: −0.06–0.36, I²=0.00%). Furthermore, subgroup and sensitivity analyses suggested that heterogeneity did not affect the results of meta-analysis.ConclusionsThis meta-analysis investigated the serum resistin levels in adult patients with NAFLD comprehensively. Patients with NAFLD had higher serum resistin levels and patients with NASH had lower serum resistin levels than healthy controls. Serum resistin could serve as a potential biomarker to predict the development risk of NAFLD.
