Objective To investigate the prevalence of hyperuricemia (HUA) in the elderly in Tanggu Community of Tianjin,and to analyze the related factors.Methods The elderly inhabitants from one community of Tanggu in Tianjin were randomly selected and their serum uric acid (SUA)levels and metabolic syndrome (MS)-related indexes were examined.There were 622 subjects with complete data (260 men,362 women; mean age 67.4 ± 6.0 years).Results The standardized prevalence of HUA in the elderly in this community was 9.1％ in total,and 7.6％ in males,10.6％ in females,and there was no significant difference between males and females (P=0.281).The levels of SUA were (283.37 ± 78.69) μmol/L in total,(315.80 ± 74.39) μmol/L in males and (260.00 ±73.31) μmol/L in females,and the SUA level was higher in males than in females (P＜0.001).The levels of blood urea,creatinine (Cr),triglyceride (TG),body mass index (BMI) were higher in patients with HUA than in patients with normal serum uric acid (P=0.000,0.000,0.002,0.049respectively).The multiple factors regression analysis showed that the SUA level was positively correlated with the levels of blood urea,Cr,TG,low density lipoprotein cholesterol (LDL-C) (P=0.000,0.017,0.000,0.019) and was negatively correlated with the levels of high density lipoprotein cholesterol (HDL-C) and fasting blood glucose (P=0.000,0.001).Conclusions The prevalence of HUA in the elderly is lower in Tanggu Community of Tianjin than in other cities in China.The SUA level of the elderly is significant higher in males than in females.The lower kidney function,hypertriglyceridemia and higher LDL-C are the risk factors for HUA,while elevated HDL-C and fasting blood glucose are associated with the decreased SUA level.

Clinical data of 380 patients with type 2 diabetes mellitus (T2DM) admitted in the Second Hospital of Tianjin Medical University from October 2014 to June 2017 were retrospectively reviewed. Patients were divided into 3 groups according to the results of lower extremity arterial ultrasonography: 103 patients without lower extremity arterial disease (group A), 132 patients with mild arterial disease (group B), 145 patients with moderate to severe lower extremity arterial disease (group C);and 100 healthy subjects served as control group. Blood routine parameters and blood biochemistry were measured;the results showed that blood cell ratios in T2DM patients were significantly higher than those in control group (P<0.05), and blood cell ratios in group B and group C were higher than those in group A (P<0.05). Pearson correlation analyses indicated that neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), hs-CRP, HbA1c, LDL-C were significantly associated with lower extremity arterial disease in T2DM patients. Logistic analysis showed that NLR(OR=2.01,95％CI:1.15-3.63,P<0.05)and PLR(OR=1.75,95％CI:1.04-3.28,P<0.05)were risk factors for lower extremity arterial disease in patients with type 2 diabetes mellitus.

Objective To investigate the variations and clinical significance of mean platelet volume (MPV),platelet distribution width (PDW) and red cell distribution width (RDW) in type 2 diabetic patients with lower extremity atherosclerotic disease (LEAD).Methods In this study,330 patients (168 male and 162 female ones) diagnosed with type 2 diabetes mellitus were recruited.According to the ankle brachial index (ABI),all the patients were divided into three groups:patients without LEAD (Group A),patients with mild to moderate LEDA (group B),and severe LEAD (group C).And 100 healthy subjects served as control group.Blood routine,fasting plasma glucose (FPG),Hemoglobulin Alc (HbAlc),blood pressure,high-sensitivity C-reactive protein (hs-CRP),blood lipids,serum creatinine and uric acid were all measured in the patients.Results MPV,PDW,RDW in all the patients with type 2 diabetes mellitus were significantly higher than those in the control group (P ＜ 0.05).Compared with the group without LEAD,MPV,PDW and RDW in the group with LEAD were significantly higher,with significant statistically difference (P ＜ 0.05).Pearson correlation analysis showed that MPV,PDW,RDW were positively correlated with the index of blood glucose and lipids.Logistic regression analyses indicated that the levels of MPV,PDW,RDW,hsCRP,HbAlc and low-density lipoprotein cholesterol (LDL-C) were significantly associated with lower extremity arterial disease in type 2 diabetes mellitus.Conclusions Patients with higher MPV,PDW and RDW levels were more likely to develop LEAD than those with lower levels.MPV,PDW and RDW were important risk factors for lower extremity atherosclerotic disease in patients with type 2 diabetes mellitus.
