MicroRNAs(miRNAs) are a type of highly conserved,small non-coding RNAs,which powerfully regulate gene expression at the posttranscriptional level.In humans,it modulates about 30％ of protein coding genes.Ocular neovascularization is one of the most important clinical problems in ophthalmology and a common cause of blindness.Recent studieshavedemonstrated that miRNAs play a crucial rolein the development of ocular neovascularization.The use of miRNAs provides novel therapeutic approaches for ocular neovascularization.Here,we describe our understanding of the functions and expressions of miRNAs in eyes,the relationship among miRNAs,ocular neovascularization and angiogenic factors,and the current research of miRNAs in diabetic retinopathy.

Background:Chronic atrophic gastritis( CAG)is a common type of gastritis and is closely related to the pathogenesis of gastric carcinoma,however,the efficacy of its drug treatment is not clear. Aims:To study the therapeutic effect of capsaicin on CAG in rats. Methods:CAG rat model was established by intragastric administration of sodium deoxycholate, ethanol and ammonium hydroxide. Forty-four survival model rats were randomly divided into CAG model group and low, moderate,high dose capsaicin groups,rats in the latter 3 groups were intragastrically administrated with 1 mg·kg-1 ·d-1 , 10 mg·kg-1 · d-1 ,30 mg · kg-1 · d-1 capsaicin,respectively,for 28 days. The inflammation and degree of atrophy of gastric mucosa were observed by HE staining. Gastric mucosal levels of pepsinogen( PG)Ⅰ,PGⅡ were determined by ELISA. The protein expressions of IKKβ,NF-κB,XIAP were determined by Western blotting. Results:The differences in inflammation and degree of atrophy of gastric mucosa,levels of PGⅠ,PGⅡ,protein expressions of IKKβ,NF-κB,XIAP were statistically significant among model group,low,moderate,high dose capsaicin groups( P <0. 05 ). With the increasing of capsaicin dose,inflammation and degree of atrophy of gastric mucosa were improved in a dose-dependent manner(P<0. 05),protein expressions of IKKβ,NF-κB,XIAP were decreased. Conclusions:Capsaicin is effective for the treatment of CAG.

Objective To evaluate the clinical significance of detecting platelet parameters in platelet transfusion patients by Investigating the relationship between platelet parameters and efficacy of platelet transfusion and prognosis.Methods A total of 50 patients who underwent platelet transfusion in our hospital in 2014 to 2016 were reviewed.Patients divided into two groups (with normal platelet counts group or subnormal platelet counts group) according to outcomes of blood biochemistry and routine after five days of platelets transfusion.Platelet parameters (platelet count,platelet distribution width,mean platelet volume,large platelet ratio) and CCI were evaluated by statistical analysis.Results The numbers of patients with CCI＞4.5 in normal platelet counts group is 21 (77.78％),that in subnormal platelet counts group is 11 (47.83％).Platelet parameters before transfusion showed no significant difference between two groups (P＞ 0.05).After transfusion,in normal platelet counts group Plt,PDW,MPV and P-LCR were significantly higher than another group (P＜0.01).MPV and P-LCR were increased in normal platelet counts group,and decreased in normal platelet counts group after transfusion.Condusion Detection of platelet parameters,especially MPV and P-LCR,is important for evaluating the efficacy and prognosis of platelet transfusion.

Objective To investigate the value of plasma H-FABP level and Acute Physiology and Chronic Health Evaluation(APACHE Ⅱ) in severity and prognosis estimation for patients with acute pumonary embolism(APE).Methods Totally 160 APE patients were hospitalized from January 2010 to January 2015 and enrolled in this study.According to the severity of the disease,these patients with APE were divided into low-risk group,moderate-risk group and high-risk group.According to clinical prognosis,these patients with APE were divided into survival groups and death groups.Plasma levels of H-FABP were measured by enzyme linked immunosorbent assay(ELISA),and APACHE Ⅱ score were analyzed.The differences of Plasma H-FABP levels and APACHE Ⅱ score were compared and which the relationship with severity and the prognosis of APE were also assessed.Results With the increased severity in patients,the H-FABP and APACHE Ⅱ score were significantly increased (P ＜ 0.05);the H-FABP and APACHE Ⅱ score were significantly higher in death group as compared with survival group(P ＜0.05).The H-FABP levels and APACHE Ⅱ score were positive correlated(r =0.71,P =0.000).ROC curves analysis results showed that the area under curve of H-FABP was 0.854 (95 ％ CI:0.784-0.927),and optimal operating point (OOP)was 13.3 μg/L,which had 81.0％ sensiticity and 79.4％ specificity;ACU of APACHE Ⅱ was 0.861 (95％ CI:0.812-0.932),and OOP was 19.2,which had 77.8％ sensiticity and 80.4％ specificity.The AUC was 0.914 (95％ CI:0.825-0.948),and the sensitivity was 88.9％,specificity was 87.6％ when the two cutoff values were both achieved,which were higher than the single H-FABP and APACHE Ⅱ score.Conclusion The H-FABP and APACHE Ⅱ score can effectively assess severity and prognosis of APE patients,meanwhile,it provide an objective basis for the clinical individual treatment and reducing the mortality rate of APE patients.
