AIM: To compare serum Lutein and Zeaxanthin (L/Z) concentrations between patients with nonproliferative diabetic retinopathy (NDR) and normal subjects,and to explore the effect of L/Z supplementation on serum L/Z level and visual function in NDR patients METHODS: Subjects were divided into three groups: 30 NDR patients supplied with Lutein 6mg/d and Zeaxanthin 0.5mg/d for three months (DR Group),30 NDR patients without L/Z supplementation (DR Control Group) and 30 normal subjects (Control Group).Serum L/Z concentrations were measured by liquid high-resolution chromatography (HPLC).Visual acuity was recorded at baseline,1 month,2 months and 3 months post initial *** L/Z concentration were measured at baseline,1 month and 2 months post initial *** sensitivity (CS) and fovea thickness were recorded at baseline and 3 months post initial ***: Mean serum lutein concentrations in DR group were 0.0686±0.0296μg/mL and zeaxanthin concentration was 0.0137±0.0059μg/*** L/Z level of DR group was significantly lower compared to the control group( lutein: 0.2302±0.1308μg/mL,zeaxanthin: 0.0456±0.0266μg/m,P = 0.000).The concentration of lutein and zeaxanthin in the DR control group at base line was 0.0714±0.0357μg/mL and 0.0119±0.0072μg/mL,*** was no significant change of L/Z concentration in the DR control group during the *** L/Z concentrations of DR group increased significantly after supplementation(F=109.124,P=0.000;F=219.207,P=0.000).Visual acuity improved significantly after *** with pre-medication,the average CS values of 1.5cpd,3cpd and 6cpd after three months increased significantly (P =0.030,0.013,0.008) and the foveal thickness decreased.(P =0.05) CONCLUSION: Serum L/Z concentrations in DR patients are significantly lower than those in normal subjects,and L/Z intake can improve the visual acuity,CS and macular edema in DR patients,suggesting that L/Z supplementation might

In order to reduce the feedback load of multi-user orthogonal frequency division multiplexing （ OFDM ） -based wireless systems, a practiral limited bits feedback precoding algorithm is proposed with direct source-destination link based on amplify-and- forward cooperative relay network under frequency selective fading channels. Using joint minimum mean square error（MMSE） filter, the receiving decoding matrix is designed for each user in the paper. Source precoding （beamforming） matrix is optimized with convex function of weight mean square error （MSE）. Relay precoding matrix is obtained under MSE decomposition and convex optimization. The precoding matrix index is fed back for clustered subcarrier of OFDM with limited feedback. Then using interpolation algorithm, all precoding matrices are achieved at base station （BS） and relay nodes. Simulations indicate the effectiveness of the proposed limited feedback joint precoding and beam_formlng design. The proposed method can improve bit error rate （BER） performance and obtain better sum-rate performance in contrast to existing algorithms. It displays the BER performance is close to that of the unquantified precoding feedback method.
