BackgroundDiabetic retinopathy (DR) is a progressive vision-threatening complication of diabetes mellitus,but its pathogenic mechanism is still unclear. Recent studies showed that it may be associated with the inflammation response of retinal capillary. Cytokines can cause induction of proinflammatory and adhesion molecules and thereby increase monocyte endothelial cell adhesion, which is now accepted as the early key event in the development of DR. ObjectiveThe present study was to determine the relationship between the stages of DR and the levels of serum vascular endothelial growth factor (VEGF) , interleukin-2 ( IL-2 ), tumor necrosis factor-alpha (TNF-α) in diabetic patients. Methods This was a pilot case-controlled study. Ninety patients with type 2 diabetes mellitus were included in this clinical trial and 30 healthy individuals were enrolled as controls. The patients were grouped into the non-diabetic retinopathy(NDR) group,background DR group and proliferative DR(PDR) group according to the results from ophthalmoscopic examination and fundus fluorescein angiography(FFA) ,with 30 patients for each group. The levels of serum VEGF,IL-2,TNF-α were assayed by ELISA and compared among the 4 groups.Written informed consent was obtained from each subject before received any related medical examination to this study. ResultsThe mean serum VEGF levels were(217.35±27. 87)ng/L,(298.31±49.26)ng/L,and(341.23±40. 18)ng/L, respectively, and mean serum IL-2 levels were( 12. 12± 1. 57 )ng/L, (16.43 ±2. 26 )ng/L, and (21.36±0. 86) ng/L,respectively and mean serum TNF-α levels were( 11.63±0. 94) ng/L, ( 17. 52±0. 65) ng/L,and(22. 01±0. 87 ) ng/L respectively in the patients with NDR ,background DR and PDR, showing significant differences from healthy controls with( 193.46±37. 39 ) ng/L for serum VEGF, ( 8. 99 ±0. 57 ) ng/L for serum IL-2 and ( 7.31 ±0. 52 ) ng/L for serum TNF-α ( F =126. 38, P＜0. 0 1 ;F =120. 37, P＜0. 01 ;F =99. 84, P＜0. 01 ). The levels of serum VEGF, IL-2, and TNF-α in the patients with the NDR,background DR and PDR were increased significantly. The level of serum VEGF showed the positively significant correlation with serum IL-2 level and TNF-α level ( r =0. 749, P ＜ 0.01 ; r =0. 631,P＜0. 01 ). The serum levels of VEGF, IL-2 and TNF-α showed a significantly positive correlation with the prolongation and severity of DR(r=0. 791 ,P＜0. 01 ;r=0. 665 ,P＜0. 01 ;r=0. 632,P＜0. 01 ). ConclusionsVEGF, IL-2 and TNF-α play active roles in the generation and development of diabetic retinopathy, and the level of serum VEGF is closely associated with the levels of serum IL-2 and TNF-α. during the development of DR.

Objective To investigate the ratios and the distribution of subjects with indeterminate results of HIV antibody in different populations who were positive for HIV screening test in Fujian and to ana-lyze the features of Western blot bands for further understanding the relationships between the Western blot band patterns and HIV infection. Methods The subjects who were diagnosed with indeterminate results of HIV antibody at the first examination were re-tested with Western blot assay every month until the results turned into HIV antibody-positive or HIV antibody-negative. Results The detection rate of indeterminate results of HIV antibody was 3. 69% in Fujian in 2015. Higher rates were detected in blood donors, pregnant woman and other clinical patients. The most common band patterns of HIV antibody-indeterminate samples were p24, gp160+p24 and gp160. Results of the follow-up confirmatory tests showed that 76% of the sam-ples of p24 band pattern were HIV antibody-negative and 76. 47% of the samples of gp160+p24 band pattern were HIV antibody-positive. The nucleic acid test showed that positive results were detected in 29 samples whose band patterns were gp160+gp120+p24,gp160+gp120+p66andgp160+gp120+p31. Conclusion The detection rates of indeterminate results of HIV antibody varied in different populations. The most com-mon band patterns of HIV antibody-indeterminate samples were p24, gp160+p24 and gp160. The more bands the samples presented themselves in Western blot assay, the more likely they would be HIV antibody-positive. Follow-up should be strengthened to prevent the spread of HIV infection. Samples with the band pattern of gp160+gp120+p24 showed a low probability of false positive and they were more likely to be end-stage AIDS with immunosuppression.

Objective To explore egg mimotope of Schistosoma japonicum that can be used in the development of diagnostic reagents for schistosomiasis.\ Methods\ By performing three rounds of biopanning in the affinity selection before picking out single clones for identification, target specific phages were effectively enriched from a random 15\|peptides phage library with an immobilized mAb 6B12 which is specific to egg antigen of S\^japonicum as a bait. By using ELISA, competitive ELISA with natural egg antigen as competitor, and Western blotting, 13 phage clones with high affinity and specificity to 6B12 were obtained and amplified from 400 single clones. \ Results \ DNA sequencing revealed that all the 13 selected single clones were identical in displaying gene sequence. Serum samples were tested by ELISA for the presence of IgG antibodies to the phages with mimic epitope, and showed that there was a significant difference between healthy volunteers and schistosomiasis patients.\ Conclusion \ It is possible that the phage display peptide antigen, egg mimotope of S.japonicum may be a replacement of natural egg antigen for the diagnosis of schistosomiasis.
