Objective To investigate the clinical efficacy and safety of topical corticosteroids as adjunctive plan in the therapy of bacterial corneal ulcers (BCU).Methods 62 eligible patients with confirmed BCU were screened and divided into 2 groups randomly.Both groups were treated with topical tobramycin for 3 weeks,the observation group received topical tobramycin for at least 48 hours and then treated with 0.02％ fluorometholone for 3 weeks,and decrement setp by step.Best spectacle corrected visual acuity(BSCVA),fluctuation of intraocular pressure (IOP) before and after therapy,time to corneal reepithelialization and clarity,severe adverse event were observed.Results After 3 weeks,BSCVA of both groups increased compared to their baselines,however,no significant difference between the two groups.Patients whose IOP exceed 21mm Hg in the control group was statistically more than that in the observation group(x2 =7.272,P ＜ 0.05).Follow up for 3 months,increasing of BSCVA in the observationgroup was significantly higher than the control group(t =2.388,P ＜ 0.05) ;and lOP of both two groups almost recuperated to baselines.Although the time to corneal reepithelialization of the control group (11.3 ± 4.5) d was shorter than observation group [(14.7 ± 5.2) d] (t =2.707,P ＜ 0.05),the recovery of corneal clarity in observation group was superior to control group (x2 =8.207,P ＜ 0.05).In addition,no severe adverse events were observed during this period.Conclusion Although prolong the healing time of corneal epithelium,corticosteroids as an adjunctive plan in the therapy of BCU may reduce immune-mediated damage,decrease scarring,control IOP fluctuation and improve BSCVA,but with no safety concerns.

This paper described the practice of using the bank card as a medical card.This practice is designed to fully leverage the financial service system of major banks in China and premium medical resources,as it may optimize medical service flows of registration,doctors' visit and charging at the hospital.This reform aims at creating an information integrating bank cards and hospital cards featuring practicality,convenience,security and high-tech,so as to improve medical service and provide the patients with a better experience in seeing doctors.

The information system of 301 Hospital One-Card service, was designed to enable outpatients to register online via mobile ends, pay in real-time, and hierarchical examination-diagnosis among other services. As the hospital HIS system cannot link to the Internet directly, the system could make use of the Internet application front end of China′s financial platform, and such means of 2D-barcodes and APP. This innovation could improve outpatient experience, keep confidential of medical information and patients′privacy, and change on-site registration to appointment in advance.

Using the enterprise resource planning(ERP)management mode,the paper analyzed the present medical insurance payment audit accounts at public hospitals,and probed into the establishment of an information management platform for medical insurance payment audit accounts in the ERP environment.The purpose is to perfect the management of medical insurance payment audit accounts,increase the efficiency of hospital's working capital,strengthen the quality and efficiency of hospital management.

Objective To investigate the effect of YTH domain family protein 2(YTHDF2)on an-giotensin Ⅱ(Ang Ⅱ)-induced hypertrophy and apoptosis of primary neonatal rat cardiomyocytes.Methods The expression level of YTHDF2 was detected in the primary neonatal rat cardiomyo-cytes with or without Ang Ⅱ stimulation(AngⅡ group and normal group).The cells were divid-ed into blank group(transfected with siRNA+PBS),siYTHDF2 group(transfected with siYTHDF2+PBS),model group(siRNA+Ang Ⅱ)and experimental group(siYTHDF2+Ang Ⅱ)to investi-gate the effects of silencing YTHDF2 on the hypertrophy and apoptosis of cardiomyocytes.West-ern blotting and RT-qPCR were used to detect the expression of YTHDF2 at protein and mRNA levels,and RT-qPCR was employed to measure the mRNA levels of myocardial hypertrophic related genes atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP)and beta-myosin heavy chain(β-MHC),and cardiomyocyte apoptosis related genes Bax and B lymphocytoma 2 gene(Bcl-2).The surface area of cardiomyocytes was observed by α-actin immunofluorescence staining.Cardiomyocyte apoptosis was observed by TUNEL staining,and the binding relationship between YTHDF2 and Bcl-2 was verified by immunoprecipitation.Results The expression of YTHDF2 at protein and mRNA levels were significantly higher in the AngⅡ group than the nor-mal group(1.49±0.03 vs 0.97±0.09,1.50±0.08 vs 1.00±0.07,P＜0.05).Compared with the blank group,the surface area of cardiomyocytes was notably enlarged,apoptotic rate was obvi-ously increased,the mRNA levels of ANP,BNP,β-MHC and Bax were significantly increased,and that of Bcl-2 was remarkably decreased in the model group(P＜0.05).The experimental group obtained decreased surface area and apoptotic rate of cardiomyocytes,lower mRNA levels of ANP,BNP,β-MHC and Bax,and increased mRNA expression of Bcl-2(P＜0.05).Conclusion Silencing YTHDF2 can alleviate Ang Ⅱ-induced hypertrophy and apoptosis in primary neonatal rat cardiomyocyte,and YTHDF2 inhibits the expression of Bcl-2 by binding to it.

Objective : To investigate the effects of melatonin ( MEL) on the proliferation of hepatic stellate cells (HSCs) induced by platelet - derived growth factor (PDGF⁃BB) and explore its correlation with the regulation of autophagy levels . Methods : The HSC⁃T6 cells were divided into the following groups : control group , model group and MEL (low , medium and high) treatment groups . After 24 hours culture , the cells adhered to the wall and were changed into serum⁃free DMEM medium to synchronize the cells to the G0 stage . After 24 hours culture , all groups were given with PDGF ⁃ BB ( 10 ng/ml) excepted the control group . Besides , melatonin of different concentrations ( 1 nmol/L , 1 μmol/L and 0. 1 mmol/L) were added immediately in three treated groups . After incubated for 48 hours , the effect of MEL on the proliferation of hepatic stellate cells activated by PDGF⁃BB was detected by CCK8 method . The protein expression levels of LC3b and α ⁃SMA in hepatic stellate cells were determined by Western blot . The expression levels of LC3b mRNA and α ⁃SMA mRNA in hepatic stellate cells were determined by qRT⁃PCR . The ultrastructure of HSCs was observed by transmission electron microscopy to understand the autophagy level. Results : Compared with control group , PDGF⁃BB could induce the proliferation of HSCs ( P < 0. 01) . Compared with model group , MEL inhibited the proliferation of HSCs activated by PDGF⁃BB ( P < 0. 01) . Compared with the control group , LC3b and α ⁃SMA protein expressions significantly increased in the model group ( all P < 0. 05) , and LC3b mRNA and α ⁃SMA mRNA expressions significantly increased in the model group (P < 0. 05 , P < 0. 01) . Compared with the model group , MEL could inhibit such effects (LC3b : P < 0. 05 , P < 0. 01 ; α ⁃SMA : P < 0. 01) . Transmission electron microscopy ( TEM) showed that compared with the control group , autopolysosome significantly increased in the model group (P < 0. 05) . Compared with model group , autopolysosome significantly decreased in MEL treatment group (P < 0. 01) . Conclusion The up⁃regulation of autophagy level can promote the proliferation of hepatic stellate cells and the inhibition of hepatic stellate cell proliferation by MEL may be related to the down⁃regulation of autophagy level .
