Diabetic retinopathy ( DR ) is one of the main blinding eye diseases for people over the age of 50, and diabetic macular edema ( DME) is the leading cause of vision loss is DR patients. The early diagnosis and early treatment is important. As OCT and FFA, mfERG, especially the retinal thickness, volume, retinal edema index quantitative indicators such as objective evaluation of macular edema, embodies the new progress of retinal imaging technology in recent years. OCT is a non -contact clinical application in recent years, noninvasive, high resolution of ophthalmic imaging examination, can do it on retinal ultrastructure observation and quantitative analysis, and the technology is relatively mature, become a routine inspection diagnosis of macular edema. Laser photocoagulation, intravitreous injection with Ranibizumab and vitrectomy is nowadays the important means for the treatment of intractable macular edema.

OBJECTIVEExpress and purify four single-stranded DNA-binding (SSB) proteins, and evaluate the binding of SSB proteins on HCV RNA.

METHODSThe expression plasmids of four SSB proteins were conducted, termed TTH, SSOB, KOD and BL21, respectively. The BL21 (DE3) was transformed by the expression plasmid of TTH, Transetta (DE3) were transformed by the expression plasmid of SSOB, KOD and BL21, then protein expression was induced with IPTG, the expression products were analysised by SDS-PAGE. To evaluate the binding of SSB on HCV RNA, RNA-SSB protein complexes were applied to a 1.2% TAE agarose gel.

RESULTSSuitable competent cells were transformed with the expression plasmids, induced by IPTG. SSB proteins were purified by affinity chromatography, to visualize their purity all SSB proteins were applied to SDS-PAGE analysis. All four proteins showed single clear bands. We have successfully obtained the SSB protein expression plasmid, expressed and purified SSB protein. TAE agarose gel electrophoresis was used to confirm SSB protein-RNA binding activity. The each of SSB-RNA complex migrated more slowly than the sole RNA, which suggested SSB protein could specifically bind to RNA.

CONCLUSIONSWe have expressed and purified four SSB proteins, and for the first time found that SSB protein can bind HCV RNA. Our results may provide a basis for future studies of the novel functions of SSB proteins on RNA.

Objective To investigate the effect of cognitive intervention on language function and quality of life (QOL) in elderly patients with post-stroke aphasia.Methods Fifty-five elderly patients with post-stroke aphasia were randomly divided into the control group (n =27) and the experimental group (n=28).The control group received comprehensive treatment including speech-language therapy (SLT),while the experimental group was subjected to additional cognitive intervention.All patients were enrolled in an eight-week rehabilitation program.The mini-mental state examination (MMSE) was used to assess cognitive function,a device for diagnosis and treatment of language disorders,ZM 2.1,was used to evaluate language function,and the 36-item short-form health survey (SF-36) (Chinese version) was used to assess quality of life (QOL),before and after treatment.Results After treatment,MMSE scores,language function scores in all categories and QOL scores in all dimensions improved in both groups (P＜0.05 for both).Furthermore,after treatment,there were significant differences between the two groups in MMSE scores of orientation,recall,attention and calculation,and in scores of overall language ability and the individual categories (P＜0.05 for all).Scores of the experimental group vs.the control group for the individual categories of language function were as follows:simple instructions (76.6 ± 14.1 vs.67.4± 19.3),complex instructions (66.1±12.8 vs.58.2±14.9),yes or no (72.5±12.1 vs.63.0±14.1),naming (55.0 19.5 vs.43.3±22.2),simple comprehension (67.5±21.4 vs.55.620.6),complex comprehension (44.8±17.0 vs.35.0±18.9),listening and reading words (65.4±16.7 vs.53.7±19.3),calculation (39.3±25.8 vs.25.9±19.2),memory (36.4±18.7 vs.26.3±17.8),matching (75.9±18.6 vs.65.3±17.1),simple general knowledge (68.3±18.2 vs.58.0±19.5),complex general knowledge (58.7±17.4 vs.50.0±13.3),orientation (70.7±19.6 vs.60.5±17.2) and comparison (59.9± 14.6 vs.50.2±17.5) (P＜0.05 for all).There were significant differences between the two groups in emotional function (66.7±18.2 vs.53.1±21.2),general health (67.2±12.6 vs.60.7±9.8),mental health (71.0±5.6 vs.63.1±4.2),social functioning (64.7±9.0 vs.59.3±10.2) and vitality (55.4±14.8 vs.46.9±15.6) (P＜0.05 for all).Conclusions Cognitive intervention combined with SLT can contribute to the recovery of language function and the improvement of QOL in elderly patients with post-stroke aphasia.

OBJECTIVE:To observe clinical efficacy and safety of Kangfuxin liquid in the treatment of pediatric hand,foot and mouth disease. METHODS:128 children with hand,foot and mouth disease were randomly divided into observation group and control group,with 64 cases in each group. Control group was given routine treatment as herpes and oral care,antibiotics for infec-tive children reflected by hemogram elevation,fluid infusion and non-steroidal analgesic-antipyretic agent based on disease condi-tion. Observation group was additionally given Kangfuxin liquid,3 ml for below 3 year-old,tid and 5 ml for more than 3 year-old,tid. Clinical efficacy of 2 groups were observed as well as CRP,lactic acid,Ig,the level of myocardial enzyme before and after treatment;the time of symptoms and signs disappearance and ADR were compared between 2 groups after treatment. RE-SULTS:The total effective rate of observation group(89.06%)was significantly higher than that of control group(70.31%),with statistical significance(P<0.05). There was no statistical significance in CRP,lactic acid,Ig and myocardial enzyme before treat-ment and IgM level after treatment between 2 groups,with statistical significance(P>0.05). CRP,lactic acid creatine kinase and lactate dehydrogenase level of 2 groups decreased significantly,while IgA and IgG levels increased significantly,and the observa-tion group was higher than the control group,with statistical significance(P<0.05). Antipyretic time,hand foot skin rash subsided time and oral ulcer healing time of observation group were significantly shorter than those of control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Kangfuxin liquid is effective in the treatment of hand,foot and mouth disease in children,and can effectively improve CRP,Ig,lactic acid,and myocardial enzyme level with good safety.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

0 05).Among them,WT but neither DN, Blank, nor Pio significantly ameliorated the increased concentrations of TGF-a1 and fibro nectin in culture medium induced by HG. Compared with DN and Blank, WT transfect ion significantly attenuated high glucose-caused elevation in c-fos, c-jun and p-ERK expression, reduction in Ⅰ-?B level, and incretio n in nucleus/cytosol ratio of NF-?B, while Pio demonstrated similarly signific ant changes only in p-ERK and NF-?B. No significant difference of GLUT-1 mRN A level was detected between HG groups. Conclusions Overexpressed PPAR?1 can su ppress increased ECM production from glomerular mesangial cells cultured in HG c ondition. Its inhibitory effects on activation of ERK/AP-1 and NF-?B pathways are involved. The further increase of PPAR?activity may have direct anti-fibr otic effect in diabetic kidney.

Aim To research the protective effect and mechanisms of taurine on myocardial ischemia and reperfusion injury in rats. Methods Myocardial ischemia reperfusion models were established in SD rats. The effects of taurine on the size of myocardial infarction and the changes of activity of SOD , and the levels of MDA and NO in myocardium and plasma of rats with myocardial ischemia and reperfusion injury were observed. Results In rats with myocardial ischemia and reperfusion injury, the taurine could reduce the size of myocardial infarction (P
