Diabetic macular edema (DME) is thickening retina with two disc diameter,which is the leading cause of blindness in diabetic retinopathy patients.The initial studies demonstrated that laser treatment of DME prevented further visual deterioration but did not improve visual acuity.Although glucocorticoid slow-release system can extend the time of effective drug concentration,to help glucocorticoid better carry out its biological effect,further studies are needed to warrant their safety due to increasing intraocular pressure and cataract progression.Novel studies identifying the presence of vascular endothelial growth factor (VEGF) in the eye with DME allowed for the development of an alternative anti-VEGF therapy,which revolutionized the management of DME by not only preventing vision loss,but also improving overall vision.Anti-VEGF therapy is becoming the first-line treatment of DME.However,present treatment modalities including anti-VEGF for DME had limitations,which build on the current understanding of DME pathogenesis.Further in-depth study of the development and outcome of DME is needed to optimize the therapeutic schemes,based on objective and scientific observation of treatment response.Finally we need to fully utilize the public health services and clinical management resources for diabetic patients,to prevent the visual impairment of DME before its occurrence.

Objective To observe the efficacy of lipoic acid combined with mosapride in the treatment of diabetic neurogenic bladder.Methods 30 patients with type 2 diabetes complicated with diabatic neurogenic bladder were treated with lipoic acid and mosapride for three weeks,on the base of good controlling of blood glucose,blood lipids,and other metabolic indicators.The residual urine volume of bladder and urodynamic indicators were compared before and after treatment.Results The residual urine volume of bladder and urodynamic indicators after treatment for three weeks and withdrawal for four weeks were (62.5 ± 27.8) ml and (61.3 ± 21.6) ml,(8.3 ± 1.9) ml/s and (7.9 ±2.1)ml/s,(10.7 ± 1.8)ml/s and (10.3 ± 1.6) ml/s,(25.6 ±2.7)cm H2O and (24.5 ±2.3)cm H2O,which were significiantly better than those before treatment [(128.3 ± 72.5) ml,(5.2 ± 1.3) ml/s,(8.4 ± 1.2) ml/s,(18.1 ±1.2)cm H2O](t=4.01,4.21,3.45,3.52,3.68,3.47,3.33,3.24,all P ＜0.01).Conclusion Lipoic acid combined with mosapride has good effect in the treatment of diabetic neurogenic bladder.

Objective To find out the dynamic variation on HCV genome to give the theoretic basis for diagnosis of post transfusion hepatitis C,and demonstrate the causality between donors and recipients suffering from post transfusion hepatitis C.Methods The high variable envelope gene fragments (HVR1 and HVR2) of HCV was selected for a cross sectional study and a one year follow up study was carried out on 3 HCV patients at every 3 month period to understand the dynamic variation of HCV HVR in each patient.Results The homology of HCV HVR genes among different types is 56.99%～60.88%,65.09%～68.80% among different subtypes,and 80.05%～96.40% among the same subtypes.It consists with the geographic distribution of HCV.The homology between the different strains isolated from the same patients is 92.10%～99.73%,95.36%～97.54 and 97.07%～99.20%,respectively.Conclusion The variation of different HCV strains in HVR is great.However,the variation of the same virus in the same patient during short infectious period is rather limited,which is no more than 7.9% per year.So the transmission pathway of some hepatitis C cases can be trailed at the molecular level by this way,and some non transfusion transmitted hepatitis C cases can be exclude

Objective To assess the blood safety under the current sero-screening program and gain experience on how to implement NAT as a routine assay for blood screening in China. Methods Sera from 103,539 non-remunerated donors of Shanghai blood center were tested by Chiron's Procleix(TMA HIV-1/HCV Assay in 2 study stages with 8 and 24 sample-pool respectively. Results 5 NAT positive samples were found to be Anti-HCV EIA-2 test positive at the same time. No window period cases of HIV-1/HCV were found in this donor group. But 275 (0.27% ) anti-HCV and 107 (0. 10%) anti-HIV false positive samples were identified by the second sero-screening. Conclusion The blood quality of Shanghai city was high to be close to the level of developed countries and the window period risk of HIV-1 and HCV was less than 1:100,000. With its high sensitivity and specificity,Procleix( TMA HIV-1/HCV Assay can be used in routine blood screening in China.

AIM: To immediately observe the complication of corneal flap after LASIK surgery.
METHODS:A retrospective case series were studies. Totally 2 040 cases ( 4 080 eyes ) from January 2010 to October 2012 in our hospital were collected, the corneal flap was observed using lamp microscope after LASIK within 30min. Corneal flap dislocation, corneal flap strial and intraface debris were examined after operation, the effective treatment and controlled measure should be taken for these complications.
RESULTS: Postoperative complications were corneal flap dislocation 102 eyes (2. 5%), corneal flapstriae 95 eyes (2. 33%), interface debris 105 eyes (2.57%). No failure case was seen. There had no corneal flap-related complications, which seriously impact the visual quality after the surgery.
CONCLUSION: Carefully postoperative examination at the first - time is an effective way to manage some complications of post - LASIK. Thus promoting the diagnosis and treatment of post-LASIK complications.

Objective To investigate the efficacy and safety of Escitalopram on panic disorder. Methods 40 patients were treated with Escitalopram. All patients were evaluated with Hamilton Anxiety Scale, Self-Rating Anxiety Scale and Adverse Drug Reactions Scale. Results All the patients released from panic since the second week after treatment, except one patient dropped because of side-effects. Other side-effects relieved during the course. Conclusion Escitalopram was effective and safe on panic disorder.

Objective To discuss the construction of training model for cooperation between doctors and nurses and evaluate its teaching effect.Methods 101 nursing students and 80 clinical medicine students were involved in an overall training for the purpose of cooperation between doctors and nurses by using of Sim-man and then test and questionnaire were conducted to evaluate the effect of the training.Results Statistics showed that training for cooperation between doctors and nurses had improved in such factors as attitude to the cooperation,communication skills,team work,and adaptability (operant skill was note included).In addition,88％ of the subjects supported the views that this kind of training should be offered before their internship.Conclusions Training for cooperation between doctors and nurses by using Sim-man can cultivate awareness of cooperation between doctors and nurses and improve team work,and set a better foundation for good collaboration between doctors and nurses.
