1.Focusing on the treatment of diabetic macular edema
Chinese Journal of Ocular Fundus Diseases 2016;32(2):119-121
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 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 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 study the anxiety and depression in patients with amyotrophic lateral sclerosis(ALS).Method One hundred and seventy-four ALS patients were evaluated by self-rating anxiety scale(SAS)and self-rating depression scale(SDS) to study the anxiety and depression in them.Results In 174 ALS patients,21 had anxiety(12.07%)and 65 the depression(37.36%). The scores of SAS and SDS in the ALS patients were significantly higher than the national norm(P<0.05).The depression incidence in the female patients was significantly higher than the male(P<0.05).Conclusions Anxiety and depression are more severe than those in ALS patients than those in normal people.Psychological support is important for these patients,especially for those female patients.

Objective To explore the diagnostic value of combined detection of serum calcium ion (Ca2+ ) ,C‐reaction protein (CRP) ,uric acid(UA) ,homocysteine(Hcy) and complement C3 ,C4 in hypertension disorders complicating pregnancy(HDCP) . Methods Patients with HDCP were enrolled as HDCP group ,and pregnant women without HDCP were enrolled as control group . Serum parameters ,mentioned above ,were detected and compared between the two groups .Diagnostic performance of the parameters was also analyzed .Results Serum levels of Ca2+ ,CRP ,UA ,Hcy and complement C3 ,C4 in HDCP group were significantly differ‐ent from those in control group(P<0 .05) .Sensitivity ,coincidence rate and correct diagnosis rate of combined detection of these six parameters were higher than single detection(P<0 .05) ,but the specificity was without significant difference(P>0 .05) .Serum lev‐els of CRP ,UA and Hcy increased with the progress of HDCP disease condition ,but serum levels of Ca2+ ,C3 and C4 decreased .Be‐tween different sub‐group of HDCP patients ,serum levels of the six parameters were with significant differences(P<0 .05) .Conclu‐sion Early combined detection of serum Ca2+ ,CRP ,UA ,Hcy and complement C3 ,C4 could be with significance for the early diag‐nosis and treatment of HDCP ,and also for the condition assessment of HDCP .
