OBJECTIVE:To investigate the method for preparation and quality control of ornidazole oral membrane.METHODS:Ornidazole oral membrane was prepared with polyvinyl alcohol and sodium carboxymethylcellulose as its adju-vants;The content of ornidazole was determined by ultraviolet spectrophotometry at the wavelength of316nm.RESULTS:There was a good linear correlation within a range of6.0～18.0?g/ml(r=0.9997)of ornidazole concentration,the average recovery was100.19%(RSD=0.66%,n=5).CONCLUSION:The established technique is simple,and the content deter-mination is quick,precise and reliable.

Planar cell polarity pathway regulates cell polarity and polarized cell movements.Recent studies in mouse models have found mutations in several genes in this pathway and specifically in the Vangl2 gene,which results in abnormalities in cardiac development,suggesting Vangl2 and this pathway play an important role in heart development.This review mainly elucidates the mechanisms regulated by the Vangl2 gene and PCP pathway during outflow tract development and the formation of the coronary vasculature.

AlM: To establish the frequency, associations and risk factors for age-related macular degeneration ( AMD ) in hospital population.
METHODS: ln this hospital based study, 589 subjects above 60 years of age were screened randomly for AMD. Participants underwent ocular evaluation and were interviewed for lifestyle variables and dietary intake of carotenoids by structured food frequency questionnaire. AMD was defined according to the international classifications and grading system.
RESULTS: Either form of AMD was detected in 48 participants. AMD was significant among diabetes, diabetic retinopathy, body mass index, heavy cigarette smokers and alcoholics ( P < 0. 05 ). Dietary lutein/zeaxanthin ( L/Z) and β-carotene intake were associated with the reduction in risk for AMD(P<0. 05).
CONCLUSlON: Higher dietary intake of carotenoids, especially L/Z, is associated with lower risk for AMD. Risk of AMD is prevalent among subjects with diabetes. Cessation of smoking and alcohol may reduce the risk of AMD in this population.

The paper elabrates the function of bibliographic management software in either managing literatures or writing papers, as well as the noted problems of college and university libraries carrying out bibliographic management software training. It also points out the importance of the software application in medical information literacy education.

Objective Evaluation of enema application of Yiyi-Fuzi-Baijiang powder combined with oral sulfasalazine enteric-coated tablets in treating ulcerative colitis. Methods The patients with ulcerative colitis were randomly divided into 2 groups, 42 cases in each group. The control group was treated with sulfasalazine, and the observation group with sulfasalazine and Yiyi-Fuzi-Baijiang powder. Both groups were treated for 4 weeks. ELISA method was used to detect the levels of IL-6, IL-8 and TNF-α. The changes of disease activity index (Sutherland DAI) were observed before and after treatment, and the clinical efficacy was evaluated. Results After treatment, the Sutherland DAI (3.89 ± 0.91 vs. 4.91 ± 1.08, t=3.082) in the observation group was significantly lower than that in the control group (P=0.042). The level of TNF-α (20.82 ± 4.31 ng/L vs. 26.51 ± 5.25 ng/L, t=3.602), IL-6 (31.73 ± 4.82 ng/L vs. 40.18 ± 5.63 ng/L, t=3.817), and IL-8 (35.39 ± 4.62 ng/L vs. 40.59 ± 5.35 ng/L, t=3.341) in the observation group were significantly lower than those in the control group (P<0.05). The total efficiency of observation group was 92.9% (39/42), and the control group was 73.8% (31/42). There was significant difference between the two groups (χ2=4.200, P=0.040). Conclusions The Yiyi-Fuzi-Baijiang powder combined with sulfasalazine could relieve the clinical symptoms of ulcerative colitis patients with spleen-kidney yang deficiency, and inhibition inflammatory response.

[Objective]To study the influence of meretrix polysaccharides on immune functions in the experimental diabetic rats.[Method]The experimental diabetic rats were yielded by streptozotocin(25mg/kg i.v)and fed with hyperotophic foods,then we used meretrix polysaccharides to treat the type Ⅱdiabetes rats and observed erythrocyte immune adherence function and T lymphocyte subsets in the experimental rats.[Results]The erythrocyte C3b receptor ratio(E-C3bRR)decreased 37.92% and the erythrocyte immune compound ratio(E-ICR)increased 64.36%,T lymphocyte subgroup(CD3、CD4、CD8)lowered 25.49%,26.54%,16.85% respectively.All of the above mentioned parameters in the model group were significantly different from that of the control group(P

This is a review of recent progress in the study on environment sensitive hydrogel based on cyclodextrin and their most recent and relevant applications in the intelligent drug delivery systems. Based on relevant literatures, the development of environment sensitive hydrogel responsive to physical, chemical and biochemical stimuli was introduced, involving their categorization, design principles, mechanism of action and potential application. Various new types of intelligent drug delivery system, which responds to various triggers, could be constructed by using the cyclodextrin-based environment sensitive hydrogel. They made it possible to control the drug release freely. Although these hydrogels are still at their research stage, they have attracted considerable interest in the intelligent drug delivery system.

Background:With the increase in pace and pressure of modern life,the aging of population,the change in dietary pattern and the challenge of social psychological problems,the overall prevalence of chronic constipation is increasing in general population in recent decades. Aims:To investigate the prevalence and associated factors of chronic constipation in medical staff. Methods:A total of 1 000 medical staffs were enrolled at random in Shanghai Ren Ji Hospital for fulfilling a questionnaire on associated factors of chronic constipation. Diagnosis of chronic constipation met the Rome Ⅲ criteria. Chi-square test and Logistic regression model analysis were performed to screen the potential risk factors for chronic constipation. The statistically significant variables revealed by chi-square test were taken into the Logistic regression model. Results:Nine hundred and eighty-six medical staffs completed the questionnaire,of them 115 were diagnosed as chronic constipation with a prevalence of 11. 7% . Multivariate Logistic regression analysis revealed that reading/ playing cell phone when defecation,working pressure,anxiety,and depression were the risk factors,which might increase the prevalence of chronic constipation;while regular life style,regular diet,drinking water,and regular bowel movement were the protective factors,which might decrease the prevalence of chronic constipation. Conclusions:Chronic constipation is prevalent in medical staff in Shanghai. Psychological factors,dietary pattern and life style,etc. are considered to be implicated in the pathogenesis of chronic constipation. Favorable life style,dietary pattern,bowel habit and mental status are associated with the reduced risk of chronic constipation.

Ligament of Marshall(LOM) is a bunch of epicardial structural deterioration.Because of its complex histological structure and electrophysiological properties, LOM plays an important role in the occurrence and maintenances of atrial fibrillation(AF).In addition, more and more studies indicated that ablation of LOM could effect the clinical result of AF treatment.We reviews on the anatomy, electrophysiological characteristics of LOM and the interrelationship between LOM and AF.
