ABSTRACT
AIM: To investigate clinical efficacy of two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin) for acute retinal necrosis syndrome. METHODS: Thirty patients (40 eyes) with acute retinal necrosis syndrome in our hospital were randomly divided into group A and B. Group A was treated with acyclovir with prednisone acetate tablets, and group B was given ganciclovir with prednisone acetate tablets and aspirin. Clinical effects in the two groups were observed and compared. RESULTS: After treatment, the overall response rate in group B (90%) was obviously higher than that in group A (70%), both of two regimens were effective, without significant difference (P>0. 05). There was no significant difference on the pre - treatment visual acuity between the two groups (P>0. 05). After different treatments, the visual acuity in group B was ≥0. 5 in 12 eyes, 0. 1≤andCONCLUSION: Two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin ) both have positive therapeutic effect, but the latter can better restore visual acuity and decrease the complications.
ABSTRACT
This study investigated the expression of interleukin-17 (IL-17) and T cell immunoglobulin mucin and domain-containing molecule-3 (Tim-3) in bronchoalveolar lavage fluid (BALF) of asthmatic mice and the effect of dexamethasone (DEX) on these factors. Thirty-six mice were randomly divided into three groups: normal group, asthmatic group and DEX group. The mouse model of asthma was established by sensitization with ovalbumin in both the asthmatic and DEX groups. The levels of IL-6, IL-10, IL-17 and TGF-β were measured in BALF by enzyme-linked immunesorbent assay (ELISA). The mRNA expression level of Tim-3 was detected by reverse transcription polymerase chain reaction (RT-PCR). The ratio of Tim-3+CD4+ cells to total CD4+ cells in BALF was determined by flow cytometry. Differential inflammatory cells in BALF were detected. The correlations among IL-17, IL-6, IL-10, Tim-3 and inflammatory cells were analyzed. The results showed that the levels of IL-17, IL-6 and Tim-3 were substantially increased and the IL-10 level decreased in BALF in the asthmatic mice, which was significantly reversed by DEX treatment. IL-17 expression was positively correlated with IL-6 and Tim-3 expression and the number of inflammatory cells but negatively with IL-10 expression. These results indicate that the increased expression of IL-17 and Tim-3 in BALF may be implicated in the occurrence and development of asthmatic inflammation; the mechanism by which DEX suppresses asthmatic airway inflammation involves down-regulation of IL-17 and Tim-3 levels.

Background The molecular biological mechanisms of diabetic retinopathy(DR)is unclear up to now.Researches have proved that endoplasmic reticulum stress(ER Stress)-associated factors are elevated in peripheral blood in patients with diabetic retinopathy.and P58 IPK can inhibit those factors.So the relationship between P58 IPK and DR is worth to investigate. Objective The aim of this study was to detect the dynamic expression of P58 IPK in the retina of diabetic rats. Methods The diabetic animal models were established in 18 clean male SD rats by intraperitoneal injection of stilptozotiein(STZ)at a dose of 60 mg/kg.The rats were sacrificed in 1,3,6 months after injection.The expression change of P58 IPK mRNA in the rats retina was detected by quantitative real-time RT-PCR.Other 6 matched normal rats were used as control groups.This experiment followed the Regulations for the Administration of Affair Concerning experimental Animals by State Science and Technology Commission. Results The rats showed more drinking,more food and more urine after STZ injection with the blood glucose level≥ 16.5 mmol/L.The success rate of diabetic models was 100%.The A value of P58 IPK mRNA/β-actin in rat retina was 0.800±0.005 and 0.975±0.008 after injection of STZ.and that of control rats was 0.725±0.006,showing statistically significant difference between them(t=22.589,t=62.784,P＜0.05).In 6 months after injection of STZ,the expression of P58 IPK mRNA in experimental diabetic rat retina was evidently lower than the eontrol rats(0.671±0.004 versus 0.725±0.006,t=-17.984,P＜0.05).Conclusion P58 IPK has a close relation to the pathogenesis of DR,and it plays a retarding role for DR.
