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.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P<0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P<0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P<0.01)and the area of microcysts was larger(P<0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P<0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

AlM:To investigate the prevalence and related high risk factors of retinal vessels disease of native Tibetan among the aged 40 and above in Maqin county, Qinghai province, China.
METHODS:The cluster sampling method was used to investigate the visual acuity and retinal vessel diseases of the native Tibetan among the aged 40 and above in Maqin county.
RESULTS:Totally 2 511 individuals were underwent the survey, among them, 29 cases (37 eyes) were of retinal vessel diseases, the prevalence was 1. 15%, 21 cases (23 eyes) were retinal vein obstruction (0. 84%), 5 cases (10 eyes) were diabetic retinopathy ( 0. 20%), 3 cases ( 4 eyes) were retinal vasculitis (0. 12%). The blindness and low vision of retinal vessels disease were 23 eyes (0. 92%).
CONCLUSlON:All the hypertension, hyperglycemia, erythrocytosis, high altitude and weight are the high risk factors of retinal vessel diseases which are the main eyes fundus disease could grow blind.

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 .
