Objective To explore the effect of the combination of benazepril and beraprost sodium on urinary microalbumin (UMA), serum high sensitivity C-reactive protein (hs-CRP) and TNF-α in patients with diabetic nephropathy(DN) in early stage. Methods From Mar. 2010 to Mar. 2013, 120 patients with early-stage DN were randomly divided into Benazepril Group, Beraprost Sodium Group and Combination Group. Each group consisted of 40 patients with medical therapy in 20-week duration. The levels of 24 h-UMA, serum hs-CRP and TNF-α were detected and compared before and after therapy. Results After treatment, the levels of 24 h-UMA, serum hs-CRP and TNF-αall decreased significantly in three groups (P<0.05) and there were lower 24 h-UMA, serum hs-CRP and TNF-αin Combination Group than those in Benazepril Group and Berapros sodium Group (P <0.05). Conclusion There is coordinating protection of combination of benazepril and beraprost sodium on diabetic nephropathy in early stage, possibly being related with the inhibiting of micro-inflammation.

Objective Researches showed that retinoic acid may be a signal molecular in the regulation of ocular axial length.Sclera is a target tissue of the pathogenesis of form deprivation myopia.Recently,guinea pigs are used to the study of the pathogenesis of form deprivation myopia.However,seldom studies are found in the change of retinoic acid level in the sclera of guinea pigs.This study was designed to investigate the role of retinoic acid of early form deprivation myopia in guinea pigs sclera.MethodsMonocular form deprivation models were established in 24 3-week-old guinea pigs by occluding the left eyes with facemask and randomly divided into form deprivation 15 days group and 24 days group.Other 6 normal guinea pigs were used as control group.The fellow eyes were used as internal control.Refraction was measured before and after experiment by using retinoscopy.Eyeballs were extracted immediately at the corresponding time points and ocular axial length was measured with outside micrometer.The level of retinoic acid in scleral samples was detected by high performance liquid chromatography.The use of animal followed the Regulations for the Administration of Affairs Concerning Experimental Animals by the State Science and Technology Commission.ResultsRefractive diptor reduced by -3.14±1.50 D in experimental eyes after form deprivation,showing statistically differences among before and various time points after form deprivation(F=23.053,P=0.000),and no significant difference was seen in reduce of refractive diptor in fellow eyes after form deprivation( -1.24±1.99 D)(F=1.506,P=0.240).The axial length was considerably increased in form deprivation eyes after experiment (F=14.551,P=0.000) but no evident change in fellow eys (F=3.612,P=0.060).The diopter and ocular axial length was significantly different between form deprivation eyes and fellow eyes (P＞0.05).The expression of retinoic acid in sclera of form deprivation eyes was higher than fellow eyes in both form deprivation 15 days and 24 days(P＜0.01).There was no significant difference in the level of retinoic acid between form deprivation 15 days and 24 days(P＞0.05).ConclusionForm deprivation myopia can be induced in 15 days after monocular occlusion.Retinoic acid levels in guinea pig sclera increased significantly during early form deprivation.

AIM: To explore the role of PI3K /PKB pathway in the growth inhibition effect of rabbit lens epithelial cells (LECs) induced by (-)-epigallocatechin-3-gallate (EGCG). METHODS: Rabbit LECs were obtained by tissue culture; MTT colormetric assay was used to study growth of LECs; Western blotting was used to study the kinsae phosphorylation- and nonphosphorylation- level of PKB. RESULTS: (1) When LECs were preincubated with 25, 50 ?mol/L LY294002 for 1 h, 50 ?mol/L EGCG had little influence on the proliferation of LECs. It showed significant inhibition when EGCG increased to 100, 200 ?mol/L ( P

Background The incidence of dry eye is growing.However,the early diagnosis of dry eye is still difficult up to now.Keratograph 5M analyzer,a novel noninvasive ocular surface analyzer for dry eye may offer important parameters.Objective This study was to evaluate the clinical value of Keratograph 5M analyzer for clinical diagnosis of dry eye.Methods An observational study was proceeded with 88 cases who accepted myopia diagnosis in Tianjin Medical University Eye Hospital from October to December 2013.A series of conventional dry eye-related examinations were performed on the patients,including tear film break-up time (TBUT),corneal fluorescein staining scoring,Schirmer Ⅰ test (S Ⅰ t),and then Keratograph 5M analyzer-related examinations were subsequently carried out,including noninvasive tear film break-up time (NITBUT) and conjunctival hyperemia scoring.The correlations between conventional dry eye-related examinations and Keratograph 5M analyzer-related examinations were assessed by using Spearman rank correlation analysis.Results A total of 88 patients were recruited with male 32 and female 56.No significant difference in age was found between different genders (P =O.34).In 88 patients,Keratograph 5M analyzer showed the non-dry eyes in 15 patients,suspicious 44 patients (50.0％) and dry eyes in 29 patients (33.0％).However,the non-dry eyes were checked out in 39 patients and dry eyes were in 49 (55.7％) based on China Dry Eye Clinical Diagnosis and Treatment Consensus.The first NITBUT (NITBUTf) was less than the average NITBUT (NITBUTav) (P =0.00),and a positive correlation was seen between them (rs =0.62,P =0.00).Dry eye grade was significantly correlated with NITBUTf or NITBUTav or conjunctival hyperemia scoring (rs =-0.60,P =0.00 ; r,=-0.89,P =0.00 ; rs =0.24,P =0.02).A negative correlation was found between the conjunctival hyperemia scoring and NITBUTav (rs =-0.24,P =0.02).However,no significant correlation was seen between conjunctival hyperemia scoring and NITBUTf,TBUT,S Ⅰ t or corneal fluorescein staining scoring (rs=-0.13,P=0.22;rs=0.16,P=0.14;rs =-0.16,P=0.13;rs=-0.08,P=0.44).No significant difference was found between TBUT and NITBUTf (P =0.71).And TBUT was correlated with NITBUTf (rs =0.23,P =0.03),but not NITBUTav (rs =0.18,P =0.09).In addition,no significant correlations were seen between S Ⅰ t and NITBUTf or NITBUTav (rs=0.20,P=0.07;rs=0.05,P=0.66).Conclusions NITBUTav has an important significance in assessing overall ocular surface conditions.The conjunctival hyperemia score is one of refrent indicators to judge ocular surface status.

Objective To compare and evaluate the performance and applications of three assays in preliminary screening of dengue infections.Methods This study was designed as a retrospective study.Clinical data were obtained from 2 137 borderline cases from September to October in 2014 and 2015.Markers of dengue infections of serum samples were detected by NS1 antigen captured ELISA, dengue NS1 detect rapid test and dengue IgM detect rapid test, respectively.Chi square test was used to compare the preliminary screening value of these 3 methods.Forty-eight diagnosed patients were also examined in the 1st-3rd day, 4th-5th day, 6th-7th days and 14th day after infection to access the sensitivities and specificities of three assays.Results Nine hundred and fifty-seven ( 57.2%) cases in 2014 and 48 ( 10.4%) cases in 2015 were diagnosed to be Dengue fever of 2 137 borderline cases.The overall sensitivity of NS1-ELISA was superior to NS1 and IgM rapid detect test (χ2 =40.865,P<0.001;χ2 =151.383,P<0.001).No significant differences were found in specificity between three assays(χ2 =0.661,P=0.416;χ2 =0.548,P=0.459; χ2 =2.397,P=0.122).The NS1 detecting assays were sensitive in 7 days after infection, but the sensitivity of IgM detecting assay increased over time.Conclusions NS1 detecting assays had good sensitivities and specificities, which can be used as an important method in preliminary screening of dengue infection.ELISA or rapid test can be selected according to epidemic situation.

Objective To explore the expression difference of cytokines related to nuclear factor kappa B (NF-κB) signaling pathway among different traditional Chinese medicine (TCM) syndromes in the patients with diabetic nephropathy (DN).Methods Serum tumor necrosis factor-α (TNF-α),interleukin-1 (IL-1),interleukin-6 (IL-6) and interleukin-8 (IL-8) in 146 patients with DN and 62 individuals undergoing healthy physical examination in the control group were measured.Results The levels of serum TNF-α,IL-1,IL-6 and IL-8 in various DN groups were significantly higher than those in the control group (P＜0.05).The levels of serum TNF-α,IL-1,IL-6 and IL-8 were significantly different among groups of different TCM syndromes (P＜0.05).With the progression of DN,all cytokines levels showed a gradually increasing trend,moreover the increased extents and time were different in different TCM syndrome types of DN.Conclusion The levels of serum TNF-α,IL-1,IL-6 and IL-8 related to NF-κB signaling pathway are correlated with different TCM syndromes types and may play a role in the occurrence and progression of different TCM syndrome types of DN.

OBJECTIVE： To confirm the efficacy and safety of latanoprost in treating glaucoma.METHODS： In a double blind， randomized control clinical trial， we compared the efficacy and adverse drug reactions of once daily topically applied 0.005％ latanoprost with those of twice daily 0.5％ timolol for 12 weeks in patients with open angle glaucoma or ocular hypertension.RESULTS： The study included 46 patients（22 pts.randomized to latanoprost treatment， 24 pts.to timolol） ， 46 patients remained at the end of the study.Comparing with baseline diurnal intraocular pressure（IOP） ， the IOP reduction（mean±standard deviation） achieved with latanoprost（7.86±2.39） mmHg， （31.1％， P<0.001），and timolol（6.24±2.58）mmHg （24.9%，P<0.001），the difference between the two groups（1.62mmHg） being significant（P<0.01）. Two patients treated with latanoprost had foreign body sensation. No other ocular and systemic adverse reactions related to the two drugs were found. CONCLUSION: The results of this study demonstrated that 0.005% latanoprost applied once daily is well tolerated and more effective in reducing IOP than 0.5% timolol applied twice daily. Thus, latanoprost has the potential for becoming one of the ideal antiglaucoma drugs.
