Objective To explore the correlations of dyslipidemia and hypertension with diabetic retinopathy in diabetic patients aged 80 years and over. Methods The 487 diabetic patients admitted to endocrine department of our hospital from January 2013 to June 2017 were recruited and their medical records were retrospectively analyzed. According to the results of examination ,they were divided into three groups :non-diabetic retinopathy group (n = 306 ) ,non-proliferative diabetic retinopathy group (n = 143)and proliferative diabetic retinopathy group (n = 38).The course of diabetes ,levels of blood glucose and lipids ,and the course of hypertension were compared among the three groups. Results Prevalence of diabetic retinopathy was 37.2% (181/487) ,and was increased along with the prolongation of diabetes duration ,and occurrence of coexisted hypertension and dyslipidemia.Statistically significant differences were found among the 3 groups(all P＜0.05)in the levels of glycosylated hemoglobin A1c ,low-density lipoprotein cholesterol ,high-density lipoprotein cholesterol ,triglyceride ,apolipoprotein A ,apolipoprotein B and the ratio of apolipoprotein A over apolipoprotein B.Multivariate analysis showed that the levels of glycosylated hemoglobin A 1c ,low-density lipoprotein cholesterol and the ratio of apolipoprotein A and apolipoprotein B were correlated with the development and progression of diabetic retinopathy ( OR = 3.00 ,0.22 and 2.96 , respectively). Conclusions The incidence of diabetic retinopathy is higher in diabetic patients aged 80 years and over.Dyslipidemia is correlated with development and progression of diabetic retinopathy.

Objective To explore the correlation between diabetic retinopathy (DR)and glycosylated blood protein(HbA1c) among diabetic patients aged 80 years and over.Methods The medical records of 403 diabetic patients(≥80 years old)admitted to endocrine department of Heji Hospital Affilicated to Changzhi Medical College from January 2013 to March 2017 were retrospectively analyzed.They were divided to three groups of non-DR group (254 cases),non proliferative DR group (122 cases) and proliferative DR group (27 cases).The duration of diabetes,levels of fasting blood glucose and glycosylated hemoglobin were compared among groups.Results One-hundred and forty-nine(37.0％)elderly diabetic patients developed DR.DR was associated with longer history of diabetes and hypertension and with family history of diabetes.There were statistically significant differences in serum levels of fasting blood glucose and glycosylated hemoglobin(both P＜ 0.05)among three groups.Furthermore,multivariate analysis showed that glycosylated hemoglobin was associated with the incidence and development of DR(OR =4.137,P＜0.01).Conclusions More than one third(37.0 ％) elderly diabetic patients(≥80 years old) have diabetic retinopathy,which is associated with the level of glycosylated hemoglobin.

Objective:To study the effects of IL-8 on the polarization of monocytes and the effects of IL-8-induced tumor-associated macrophages(TAMs)on the invasion and metastasis of hepatocellular carcinoma(HCC).Methods:After exogenous IL-8 stimulation of THP-1 cells for 72h,the percentages of M1 and M2 TAMs were examined.RT-PCR and Western blot assays were used to study epitheli-al-mesenchymal transition(EMT),and wound-healing and transwell assays were preformed to study the invasion potential of HCC cells after co-culturing with TAMs and HCC cell lines in vitro.Lastly,100 cases of HCC tissue samples were used to validate the correlation among TAM numbers,IL-8,and EMT features of HCC cells via immunohistochemistry(IHC)staining methods.Results:Exogenous IL-8 induced significant M2 polarization of TAMs in THP-1 cells.TAMs further promoted EMT in HCC and enhanced the invasion potential of HCC in vitro.Finally,significant positive correlations among the numbers of TAMs,IL-8 expression,and N-cadherin expression were identified in primary HCC tissue samples(r=0.22,r=0.20,P<0.05).Conclusions:IL-8 locally attracted and activated TAMs,and promot-ed M2 polarization of TAMs,which further promoted the EMT and invasion potential of HCC cells both in vitro and in vivo.
