Objective To find out the problems in information service for diabetic patients by investigating their use of information service. Methods The enthusiasm and channels to access information in diabetic patients and the types of information they wanted were investigated in 14 Wuhan hospitals, which were analyzed by descriptive sta-tistics, chi-square test, and Five-Point Likert Scale scoring. Results About 1/3 of the patients never initially searched the health information on diabetes,the majority of the patients acquired the health information on diabetes from medical institutions,diabetic patients did not show enough concern for the information on the etiology,influencing factors and treatment plan of diabetes. Conclusion Diabetic patients lack of enthusiasm to access information,medical staff and medical institutions are the chief force of information service for diabetic patients, and the special informa-tion accessed by diabetic patients is quite less.

It was found that the training targets, offered courses and training levels differed greatly in China and foreign countries by comparing the domestic and foreign education of health information management and the offered courses for undergraduates in 8 foreign and 11 domestic medical universities , indicating thateducation of healthin -formation management should be internationalized and standardized with the IMIA international recommendations as its guidance , its training target defined, and its course system rationalized .

OBJECTIVE:To systematically review the effectiveness and safety of methotrexate(MTX)in the treatment of rheuma-toid arthritis,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline,EMBase,Cochrane Library,PubMed,CJFD,CBM,VIP and Wanfang Database,randomized controlled trials(RCT)about MTX in the treatment of rheu-matoid arthritis were collected,Meta-analysis was performed after data extraction and quality evaluation. RESULTS & CONCLU-SIONS:33 effectiveness evaluation were included,involving 8 253 patients,and 53 safety evaluation were included,involving 4 803 patients. Results of analysis show,the efficacy of MTX was not higher than leflunomide in the treatment of rheumatoid arthritis,superi-or to cyclosporine A,and similar to sulfasalazine. In addition,MTX shows similar efficacy with etanercept(7.5-20 mg per week),goli-mumab,adalimumab or rituximab,but less effective than trastuzumab. The incidence of adverse reactions of MTX is high,but mainly mild or moderate,and the most common adverse reactions are gastrointestinal symptoms. Oral administration of MTX is more secure than intramuscular injection and subcutaneous injection.

OBJECTIVETo study effects of polysaccharide of Radix Ranunculi Ternati (PRT) on immunological function and anti-oxidation activity of mouse.

METHODCell proliferations of splenocyte, thymocyte and peritoneal macrophage were measured by MTT colorimetry. The phagocytic function of peritoneal macrophage was measured by neutral red colorimetric method. The disoxidation power of PRT was measured by Prussian blue method. The clearing effect of PRT on hydroxyl radical was measured by salicylic acid capture method. The clearing effect of PRT on superoxide anion free radical was measured by pyrogallol auto oxidation method.

RESULTPRT among 25-400 mg x L(-1) could enhance thymocytes and spleen lymphocyte proliferation and macrophage phagocytosis. PRT(200 mg x L(-1)) has the strongest macrophage proliferation. PRT in different concentration has shown some disoxidation effects. PRT in 8 g x L(-1) has nearly the same ability of clearing x OH by Vit C with the same concentration. The clearance rate of PRT on O2*- is 95.39%.

CONCLUSIONPRT can enhance the cell proliferation capability of thymocytes, spleen lymphocytes and peritoneal macrophages. PRT can enhance macrophage phagocytosis in a dose-response relationship. PRT has saome disoxidation power and strong ability of clearing x OH and O2*-.

OBJECTIVE: To understand the relationship between porosity, collagen fiber orientation and strength of the plated bone after rigid plate fixation and removal. METHODS: Seventy-two New Zealand white rabbits were used in this experiment. Eight animals served as control and the other sixty-four were plated on their intact left tibiae with stainless steel (316L) 4-hole plates to induce early osteoporosis. The plates were removed 2 months after internal fixation in 40 plated animals, 8 of which were sacrificed immediately following plate removal and the other 32 were killed in successive groups with 8 in each group 1, 2, 3 and 4 months after plate removal. The remaining 24 plated animals were killed at 3, 4 and 6 months after plate fixation. After sacrifice, the samples of plated bone were prepared for light microscope, quantitative histological analysis, polarized light microscope and biomechanical test. RESULTS: The internal fixation with a rigid plate could induce the regional osteoporosis which manifested both bone loss and disorganized bone structure (loss of the orientation of the collagen fibers) leading to decreased strength of the plated bone. Although the regional osteoporosis could recover gradually after plate removal, the bone structure remained disorderly even when the bone mass returned to normal. Delayed restoration of bone structure was related to delayed restoration of bone strength. CONCLUSIONS: Besides the bone loss, the disorganized bone structure is the main cause of decrease of bone strength after rigid plate fixation and removal.

Zinc transporter 8 (ZnT8) is an important candidate antigen for type Ⅰ diabetes. The autoantibody detection kit based on ZnT8 can be used to help diagnose type Ⅰ diabetes, and the related products have been launched in Europe and the United States. Since the recombinant production system of active ZnT8 has not been established in China, this key raw material is heavily dependent on imports. We used Saccharomyces cerevisiae to carry out the recombinant expression of ZnT8. First, multiple antigenic forms of ZnT8 were designed as C-terminal haploid (C), C-terminal diploid (C-C), and N-terminal and C-terminal concatemers (N-C). The proteins were expressed, purified and tested for antigenicity by bridging-type ELISA. The serum of 13 patients with type Ⅰ diabetes and the serum of 16 healthy volunteers were detected. C, N-C, and C-C proteins had similar detection rates, which were 53.8% (7/13), 61.5% (8/13) and 53.8% (7/13). The specificity of the three groups was 100% (16/16). The detection value on positive samples P3, P4, and P8 increased by more than 90%, indicating better serum antibody recognition ability. Finally, N-C protein was selected for further serum sample testing, and the test results were characterized by receiver operating characteristic (ROC) curve for sensitivity and specificity. Compared with imported gold standard antigen, the sensitivity was 76.9% (10/13) and the specificity was 87.5% (14/16). There was no significant difference in the sensitivity of the method, but the specificity needed to be improved. In conclusion, the ZnT8 N-terminal and C-terminal concatemer protein developed based on S. cerevisiae expression system is expected to be a key alternative raw material in the development of in vitro diagnostic reagents for type Ⅰ diabetes.
