Objective To analyze the urine trace albumin(mALb)/creatinine(Cr) ratio and blood uric acid(UA),and other various metabolic index level in patients with diabetic nephropathy(DN),combined with clinical data such as patients' age,body mass index(BMI),course of diseases,to explore the related mechanism of occurrence and development of DN.Methods 76 DN patients were selected.The microalbuminuria group(urinary mALb/Cr<300μg/mg) had 46 cases,the clinical albuminuria group(urinary mALb/Cr≥300μg/mg) included 30 cases,another 49 diabetic patients without kidney damage were seleted as control group.The urinary mALb/Cr,blood UA,fasting blood glucose(FBG),triacylglycerol(TG),total cholesterol(TC),high-density lipoprotein(HDL),low density lipoprotein(LDL),glycosylated hemoglobin(HbA1c) levels were determined.The BMI and the length of the course of the disease calculate.Results The patients' age,course of the disease,urinary mALb/Cr,blood UA,FBG,TC,TG,LDL,HbA1c and BMI level in the clinical albuminuria group and microalbuminuria group were significantly higher than those in the control group,the differences were statistically significant (F=6.18,12.48,141.43,12.48,8.49,4.98,6.18,3.89,3.17,3.89,all P<0.05).The high uric acid hematic disease rates of the clinical albuminuria group and microalbuminuria group were 26.09% and 26.09%,which were significantly higher than 10.20% of the control group,the differences were statistically significant(x2=4.074,24.833,all P<0.05).Urinary mALb/Cr was positively correlated with age,duration,BMI,UA,TG,TC,LDL,FBG,HbA1c(r=0.120,0.299,0.148,0.340,0.157,0.149,0.103,0.487,0.103).Multiple linear stepwise regression analysis suggested that duration,blood UA,FBG were independent risk factors of urinary mALb/Cr;TG,BMI,urinary mALb/Cr were independent risk factors for blood UA.Conclusion Urinary mALb/Cr and blood UA are the independent risk factors,high uric acid hematic disease may participate in the development process of DN,and diabetes duration,UA,BMI,TG,TC,LDL,FBG,HbA1C associated with increased urinary mALb/Cr excretory DN patients,the effective monitoring can improve the symptoms of DN and quality of life.

OBJECTIVETo isolate exosomes from rabbit aqueous humor and to investigate their immunosuppression function.

METHODSAqueous humor was collected from 40 New Zealand rabbits and exosomes were isolated by fractional separation and ultracentrifugation methods; the morphology was studied with electron microscopy. The immunosuppressive-related proteins of exosomes were detected with Western blotting; their inhibitory effect on ConA-induced proliferation of T lymphocyte was estimation with CCK-8 cells proliferation assay.

RESULTSEight milliliters of aqueous humor were collected from 40 New Zealand rabbits and 200 μg exosomes was yielded. Under electron microscope, the exosomes had typical structure of lipid bi-layer with a diameter of 50-100 nm. The results of Western blotting showed that these exosomes expressed Hsp70, CD9 and Alix but not Grp94, presenting a typical exosomes protein profile. Moreover, exosomes expressed high level of TGF-β and significantly inhibited the proliferation of T lymphocytes.

CONCLUSIONImmunosuppressive exosomes can be isolated from rabbit aqueous humor, which may be involved in immunotolerance of the eye.
