Age-related macular degeneration (AMD) can cause irreversible severe visual impairment.At present,a large number of basic and clinical research has documented several effective treatment for wet AMD.As for dry AMD,so far there is no effective therapy and preventive measure.Dry AMD probably worse for macular choroidal neovascularization (CNV) or geographic atrophy (GA) to its later stage,resulting in severe visual impairment.In recent years,some promising treatment strategies are emerging,mainly in the prevention of the damage of photoreceptor and retinal pigment epithelium,such as drug therapy,laser photocoagulation,surgery,plasma exchange,stem cell transplantation and gene therapy.These therapies are expected to be able to bring hope for arresting the development of dry AMD.This article reviews the current researches and possible future management of dry AMD.

Age-related macular degeneration (AMD) is the leading cause of the irreversible vision loss in population over 55 years of age.With the increasingly serious problem of aging,the prevalence of AMD is rising year by year.However,as the pathogenesis of dry AMD is largely unknown,the effective therapy still is lack.Given that there was a lack of proper animal models,it brought about obstacles to researches about molecular mechanism underlying dry AMD.Nowadays,lots of murine models of dry AMD have been established and developed,which provide suitable tools for relevant researches.But,different dry AM D models show varied pathogenesis features,and a reasonable choice of models is very important for different studies.The characteristics of different dry models were reviewed in this article.

In order to achieve the demand of clinical diagnosis,treatment and research based on TCM clinical literature,we conducted the questionnaire to doctors of Chinese medicine on their demands for medical information in the process of clinical diagnosis and treatment,hoping to make certain the direction and service methods of TCM clinical research database from the actual demands of doctors.

Objective:To investigate the effect of sonodynamic therapy with hematoporphrin on the expression of VEGF in Chick Chorioallantoic Membrane and provide experimental basis for appling sonodynamic therapy(SDT)on anti-angiogenesis in tumor therapy.Methods:The hatching eggs cultured for 7 days were randomly divided into 4 groups:blank control group,ultrasound group,hematoporphrin group,sonodynamic therapy group.The express of VEGF in CAM was detected by immunity histochemistry.Result:There were significant differences between control group and ultrasound group(P0.05),conclusion The results show that sonodynamic therapy with hematoporphrin has a significant inhibitionary effect on the express of VEGF in CAM and this maybe is the most important mechanism of its anti-angiogenesis effect.

Objective To investigate the prevalence of depression in hemodialysis patients with end‐stage renal disease(ESRD) , and evaluate its related factors .Methods One hundred and twenty four ESRD patients undergoing hemodialysis were assessed by using Beck depression inventory (BDI) .Baseline characteristics and laboratory test items were compared between depression group and non‐depression group .Results The prevalence of depression detected by BDI was 56 .5% in hemodialysis patients with ESRD . Gender and occupational status were statistically different between depression and non‐depression groups(P<0 .05) .Higher preva‐lence was found among female and non‐working patients .However ,there was no difference on age ,hemodialysis time ,education , marriage and incoming(P>0 .05) between the two groups .In laboratory test ,the white blood cell and urine acid levels in depression group were significant higher than that in the non‐depression group(P<0 .05) .Conclusion Depression is prevalent in ESRD pa‐tients undergoing hemodialysis ,especially in female and non‐working patients and always combined with higher white blood cells and urine acid levels .

To establish an HPLC method for the determination of content and content uniformity of minoxidil tablets. Methods:An Xbridge C18 column (250 mm ×4.6 mm, 5 μm)was used with methanol-0.03 mol·L-1 KH2PO4 solution -triethyl-amine(60∶40∶0. 1)(adjusting pH to 3. 5 with phosphoric acid ) as the mobile phase. The flow rate was 1. 0 ml·min-1 and the detec-tion wavelength was 287 nm. The column temperature was 30℃ and the injection volume was 10 μl. Results:There was a good linear relationship within the range of 8. 056-32. 224 μg·ml-1(r=0. 999 9). The average recovery was 99. 68%(RSD=0. 36%,n=9). The average content of 3 batches of samples was 100. 2%,100. 5% and 99. 8% and the content uniformity was 5. 5,6. 2 and 4. 9, re-spectively. Conclusion:The method is simple and accurate with good reproducibility, which can be used in the quality control of mi-noxidil tablets.

ObjectiveTo compare the clinical efficacy and side effects of liver damage of the methylprednisolone (methylprednisolone tablets ) and prednisone treating nephrotic syndrome compicated with hepatitis B.Methods66 patients with nephrotic syndrome complicated with hepatitis B were randomly divided into control group and observation group,and each group had 33 cases.The control group was given prednisone in the morning,while the observation group was received methylprednisolone.The clinical efficacy and side effects of liver damage were compared between the two groups.ResultsAfter the treatment,the biochemical index significantly improved compared with the pre-treatment( all P ＜ 0.05 ) ;The total effective rate of observation group was 93.94％ higher than 84.85％ of the control group( x2 =1.44,P ＞ 0.05 ).However,there was no significant difference between the two groups( P ＞0.05) ;The observation group was significantly higher than the control group in negative rate of HBV-DNA (x2 =4.69,P ＜ 0.05 ) ;The side effects of liver damage in the observation group were lower than the control group (t =5.62,5.13,P ＜ 0.05 ).ConclusionMethylprednisolone and prednisone for treating patients with nephrotic syndrome compicated with hepatitis B had good clinical efficacy,and methylprednisolone was more effective than prednisone,especially it had less side effects of liver damage than prednisone.

Bispheno|A(BPA)is an endocrine disruptor with estrgenic properties,which is a widely used industrial platicizer.When exposure to BPA for long-term,it would impact on multiple systems and organs including reproductive.developmental,neurological,endocrine function and so on,particularly in obesity.ExpoSUre to BPA during pregnancy and postnate,it can increase the sensitivity to obesity in offsprings.BPA may be contributed to obesity by enhancing triglyceride accumulation and accelerating adipocytes differentiation,affecting endocrine function of adipocytes and blood glucose and insulin metabolism.However,the dosage effect of BPA is not a simple linear rehionship.The impact of environment-related dosage on the human is worthy ot research in future.

Objective:To establish an HPLC method for the determination of two components in aspirin and phenobarbital pow-ders.Methods:AThermoBDSC18column(250mm×4.6mm,5μm)wasusedwithacetonitrile-methanol-0.01mol·L-1KH2PO4so-lution -triethylamine(10∶35∶55∶0.1)(adjusting pH to 3.5 with phosphoric acid )as the mobile phase.
