Objective To find out a more rational pathological classification criteria for renal injury in patients with type 2 diabetes mellitus. Methods The renal clinicopathological features of forty-nine type 2 diabetic patients with maeroalbuminuria were collected and were compared retrospectively. The patients without diabetic renal disease were excluded. According to the pathological features, the patients were divided into two groups: typical diabetic glomerulopathy (DG) and atypical diabetes-related renal disease (ADRD). Results The renal biopsy revealed DG accounted for 59.2% of the patients, while the remaining 40.8% presented atypical renal injury defined as ADRD. In DG group, volume fraction of mesangium per glomerulus, glomerular basement membrane width, atrophic tubules index, intersititium injury index and prevalence of hyalinization of renal arteriole were higher; podocyte density per glomerulus was lower; duration of type 2 diabetes was longer; the level of fast blood glucose, systolic blood pressure, mean arterial pressure, proteinuria and prevalence of diabetic retinopathy (DR) were higher; glomerular filtration rate (GFR) was lower. In ADRD group, body mass index and prevalence of obesity were higher; dyslipidemia was more severe. GFR was negatively correlated with glomerular global sclerosis rate in both DG and ADRD group. Proteinuria was positively correlated with volume fraction of mesangium per glomerulus in DG. No correlation between proteinuria and pathological features was found in ADRD. DR (94.8%) and duration of type 2 diabetes over five years (90.7%) had high negative predictive value for DG. Conclusions Renal injuries in type 2 diabetes patients are heterogeneous. ADRD is an atypical renal injury in type 2 diabetes patients whieh is different from DG. DR and duration of diabetes are more helpful in predicting DG separating from ADRD.

Objective To study the pathologic pattern and clinical feature of type 2 diabetes mellitus complicated with chronic kidney diseases (CKD). Methods Clinicopathological features of 155 type 2 diabetic patients complicated with CKD were collected and analyzed retrospectively. The patients were divided into four groups: typical diabetic glomerulopathy (DG),atypical diabetes-related renal disease (ADRD), non-diabetic renal diseases (NDRD) and DG complicated with NDRD. Results Renal biopsies revealed DG accounted for 18.7% of the patients, ADRD accounted for 12.9%, NDRD accounted for 60.0%, and DG complicated with NDRD accounted for 8.4%. In DG group, duration of type 2 diabetes was longer;the level of fast blood glucose, systolic blood pressure, mean arterial pressure and prevalence of diabetic retinopathy (DR) were higher;proteinuria was heavier and evaluated glomerular filtration rate (eGFR) was lower. In ADRD group, body mass index and prevalence of obesity were higher;dyslipidemia was more severe. Gross hematuria and acute renal insufficiency could be only found in NDRD group.Without DR, duration of diabetes under 5 years, gross hematuria, acute renal insufficiency,evidences of autoimmune diseases and proteinuria≥3.5 g/24 h but eGFR ≥60 ml/min were specific valuable predictors for NDRD. Conclusions Renal injuries in type 2 diabetic patients are structural heterogeneous, in which NDRD is more common and is different from ADRD and DG.Renal biopsy should be considered when type 2 diabetic patients complicated with CKD present at least one characteristic as follows: duration of diabetes under 5 years, without DR, history of gross hematuria, acute decrease of renal function, evidences of autoimmune diseases and proteinuria ≥ 3.5 g/24 h but eGFR ≥ 60 ml/min.

Objective To observe the effects of subretinal transplantation of rat mesenchymal stem cells (rMSCs) on Sodium Iodate (SI)-induced retinal degeneration.Methods One hundred and twenty Brown-Norway (BN) rats were divided into three groups including SI injection group,rMSCs transplantation group and normal control group,each with 40 rats.The retinal degeneration was induced by caudal vein injection of SI.The retinal pigment epithelium(RPE)and neural retinal were evaluated by ocular fundus photograph,fluorescein fundus angiography (FFA),electroretinogram (ERG) and histological approach,and TUNEL(terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling).CM-Dilprelabeled primary rMSCs were transplanted into the subretinal space of Sl-induced rats.The survival,integration,and differentiation of rMSCs were observed between 14 day to 60 day after the transplantation.Results The rat retinal function was gradually reduced afterl4 days of SI injection,with a time-dependent manner.After the RPE cells were damaged,the outer segments of photoreceptors became disrupted and shortened until karyopyknosis.The nuclear morphology and positive TUNEL labeling indicated that the death of photoreceptor cells was apoptosis.After rMSCs transplantation,CM-DiI labeled donor cells were observed to be scattered in the subretinal space and expressed RPE cell markers.Average amplitude of bwave and Ops (oscillation potential) in ERG improved 27.80%,59.38% respectively after rMSCs transplantation.Conclusions Transplanted rMSCs can survive in subretinal space and differentiate into RPE cells,thus cure SI- induced retinal degeneration.
