OBJECTIVETo investigate the effects of advanced glycosylation end products (AGEs) modified bovine serum albumin (AGE-BSA) on the expression of reactive oxygen species (ROS) and monocyte chemoattractant protein-1 (MCP-1) in human renal mesangial cells (HRMCs).
METHODSHRMCs were cultured in vitro with medium containing different doses of AGE-BSA or BSA (50,100, 200, 400 mg/L) for 48 hours, or with AGE-BSA (200 mg/L) for different times (12, 24, 48, 72 h). Immunocytochemistry assay was used to estimate the protein level of RAGE. The ROS in cells were measured by flow cytometry and the mRNA expression of MCP-1 were analyzed by semi-quantiative reverse transcription-polymerase chain reaction (RT-PCR) after treatment with AGE-BSA or BSA.
RESULTSThe protein level of RAGE was upregulated in the HRMCs with AGE-BSA. The expression of ROS and MCP-1 significantly enhanced by incubation of AGE-BSA in a time- and dose-dependent manner. The effects of AGE-BSA-induced up-regulation of ROS and MCP-1 level was significantly blocked by neutralizing antibodies to RAGE, while the expression of ROS and MCP-1 stood nearly unchanged after cultured with huamn IgG.
CONCLUSIONThe expression of ROS and MCP-1 in HRMCs is induced by AGE-BSA through RAGE, which may have potential effects in the pathgenic mechanism of diabetic nephropathy.

Objective To systematically evaluate the association between vascular endothelial grow th factor‐C (VEGF‐C) ex‐pression in breast cancer tissue and clinical significance in the domestic patients with breast cancer by a Meta‐analysis .Methods The published case controlled trials on the VEGF‐C expression and the clinical manifestations of breast cancer were retrieved from the CNKI ,CBM ,VIP and Wanfang databases ,and other relevant journals were also manually retrieved to identify all the relevant case controlled trials .The retrieval year limit was from the database establishment to June 2014 .The included literatures were screened according to the inclusion and exclusion standards and the quality of included case controlled trials was assessed .The Rev‐Man 5 .2 software was used to conduct the Meta analysis .Results A total of 15 case controlled trials involving 975 patients with breast cancer were included .The Meta analysis results revealed that there were statistical differences in the VEGF‐C expression be‐tween the breast cancer group and the control group[OR = 8 .16 ,95% CI(5 .77 ,11 .54)] ,between the lymph node metastasis posi‐tive group and the non‐lymph node metastasis negative group[OR = 5 .19 ,95% CI(3 .63 ,7 .44)] and between the clinical stage Ⅰ -Ⅱ group and the stage Ⅲ - Ⅳ group[OR = 0 .35 ,95% CI(0 .21 ,0 .59)] ;the difference in the VEGF‐C expression between the 0 - <50 years group and the ≥ 50 years group had no statistical significance ,indicating that the VEGF‐C expression had no obvious as‐sociation with the patient′s age .Conclusion The present evidences reveal that VEGF‐C maybe participate in the development and progression process of lymph node metastasis of breast cancer and may be become an important factor influencing the prognosis of breast cancer .

Objective To study the effects of fetal lamb cardiac bypass on the fetal cardiac function.Methods Eight ewes at gestation of 120 to 140 days have nine fetus which were randomly divided into control group (n = 4) and fetal bypass group (n = 5). Control group underwent sham procedure that fetal stemotomy was performed.Bypass group underwent fetal cardiac bypass with cen- trifugal pump and placenta for 30 minutes.Fetal mean blood pressure,heart rate and bleed gas data were recorded before bypass,30 minutes during bypass,1 hour after cessation of bypass,2 hour after cessation of bypass.Tei index of two ventricles and pulse index of umbilical arteries were recorded with ultrasonography.Plasma troponin I was assayed.Ultrastructure of fetal myocardium was recorded,Results Fetal mean blood pressure and heart rate of two groups have no changes during the experiment time.The umbilical pulse index of bypass group elevated significantly compared with control group (P

As the increasing population aging,the incidence of age-related macular degeneration is increasing,blinding rate also increasing,so it is very important for the early diagnosis and treatment of age-related macular degeneration.There are many methods to check the aging macular degeneration,such as fundus angiography,optical coherence tomography (OCT),visual field and multifocal electroretinogram (mfERG).In recent years,many emerging ophthalmic methods have emerged and are gradually applied to clinical diagnosis,including optic coherence tomography angiography (OCTA).The function of these methods has its unique advantages,but there are also limitations.This paper will review these existing methods.
