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.

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 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 .

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.

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.

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.

Objective:This study explores Achenbach's three famous checklists regarding to children's behavior problems:CBCL,YSR,TRF.The checklists are translated into Chinese and tested for their relativity and applicability.Methods:1410 adolescents selected from 6 middle schools in Beijing are investigated with CBCL,YSR and TRF.Results:The Cronbach ? among the items of the three checklists and the total score are 0.96,0.95,and 0.99 respectively,the split-half reliability are 0.93,0.89,and 0.97 respectively,which demonstrates an obvious homogeneity within the three checklists.Scores in YSR are generally higher than those of the other two checklists, scores in CBCL follow immediately,and scores in TRF are the lowest(except for a minority of individual factors). The scores in CBCL and YSR are significant correlated(r=0.35～0.60,P

Real-time three-dimensional echocardiography(RT-3DE) has been validated for its accurate diagnoses and quantitave mearsurement of mitral valve disease,which could act as a guide in selecting the proper therapeutic strategy for each individual in clinical setting.In this article,the recent research achievements on RT-3DE in mitral valve disease were summarized,and the application of RT-3DE in surgical approach to mitral valve disease was discussed as well.

Objective:To develop a method to simultaneously determine the content of imperatorin, isoimperatorin and magnolin in Quchuan capsules by HPLC. Methods:A Shiseido CAPCELL PAK C18 column(150 mm × 4. 6 mm,5 μm) was used. The mobile phase consisted of acetonitrile(A)-water(B) with gradient elution at a flow rate of 1. 0 ml·min-1 and the column temperature was at 30℃. The detection wavelength was set at 278 nm from 0 to 25 min and 248 nm from 25 to 70 min. The injection volume was 10 μl. Results:The linear range of imperatorin,isoimperatorin and magnolin was 6. 126-55. 134 μg·ml-1(r=0. 999 7), 9. 862-88. 758 μg ·ml-1(r =0.999 8) and 4.830-43.470 μg·ml-1(r =0.999 8), respectively. The average recovery was 101.5% (RSD =1. 4%), 99. 6%(RSD=1. 2%) and 100. 2% (RSD=1. 7%), respectively. Conclusion: The method is convenient, sensitive and accurate, which can be used for the quality control of Quchuan capsules.
