OBJECTIVE: To probe into the cognition of the elderly to the safety of drug use and their demand for pharmaceutical care,and to improve pharmaceutical care in the hospital and guarantee the safety of drug use.METHODS: Questionnaires about medication information were designed.315 elderly patients,who were collected from 10 old-age homes of Liaocheng,domestic sickbed department and 5 community medical service stations of Liaocheng Municipal People's Hospital from Oct.2008 to Mar.2009,were involved in study.Investigation data were analyzed statistically using SPSS17.0 software.RESULTS & CONCLUSIONS: Results of study showed that the elderly had not sufficient knowledge towards the safety of drug use,especially drug allergies,side effects of drugs and special population medication.There was significant difference in the understanding of the safety of drug use among the elderly with different education levels,different occupations and different medical insurance patterns.The potential danger of medication is present.They are desirous of acquiring pharmaceutical care.Pharmacists should carry out medicine consultation and popularize pharmaceutical knowledge.They also should provide a comprehensive pharmaceutical care for the elderly people to ensure the safety of drug use in the elderly.

Immunoblotting(IB) technique has been frequently used to detect bullous pemphigoid (BP) antibodies in BP patient.It is important to extract the antigen proteins fully and intactly in the base membrane zone(BMZ) of normal human epidermis.The simple method of extracting antigens will make IB techniqne easy.Three different methods of extracting antigen proteins were compared.Using IB for detecting BP antibodies,it has been found that the results of epidermal extract preparations are basically similar.However,one of these methods (NO.1) is more convenient and may obtain more amounts of antigens.Another method(No.3) is identical to that of extracting antigens in dermis for de- tecting epidermolysis bullosa acquista (EBA) antibodies.Therefore,in using IB technique to distinguish BP from EBA,one can apply method No.3.

Objective To investigate the predictive value of ADC value in grading of neuroepithelial tumors. Methods The clinical data and images of 70 patients with neuroepithelial tumors pathologically proven were collected and analyzed restrospectively. All the patients were classified into low(WHOⅠ or Ⅱ)and high(WHO Ⅲ or Ⅳ)grade groups which included 40 and 30 cases respectively accroding to the 2007 WHO classification of tumours of the central nervous system. All the patients underwent plain and contrast-enhanced MR scan and DWI before surgery. The minimum ADC(MinADC)value was measured postoperatively on ADC maps. The Ki-67 labeling index(Ki-67 LI)of tumor tissue was determined by immunohistochemistry.MinADC values for two groups were analyzed using student t test, while the age and Ki-67 LI for the two groups was analyzed using Mann-Whitney test(P＜0.05 considered to be significant＝.Also the MinADC valHe and Ki-67 LI were analyzed with Pearson correlation. The receiver operating characteristic analysis was used for evaluation for grading neuroepithelial tumors of the patients using MinADC. Results The mean MinADC value[(1.08±0.31)×10~(-3) mm~2/s]of the low grade group was significantly higher than that[(0.74±0.18)×10~(-3) mm~2/s]of the high grade group(t=5.42,P＜0.05＝,and the Ki-67 LI of the low grade group[0-50%,median 4%]was significantly lower than that[0-75%,median 25%]of the high grade group(U=325.50,P＜0.05＝.There was a negative correlation between MinADC value and Ki-67 LI(r=-0.30,P＜0.05＝.The area under the ROC curve was 0.85,and the cutoff MinADC value of 0.86×10~(-3) mm~2/s for the differentiation between high and low grade neuroepithelial tumors provided the best combination of sensitivity(90.0%)and specificity(77.5%)(receiver operatingcharacteristic analysis).Conclusion MinADC value is helpful for prediction of neuroepithelial tumor grade.

As a new biotechnology, protein transduction connects the target fragment with biology active and protein transduction domain, and transducer it in to cells, exert its biological effects. Protein transduc-tion domain is a small molecule peptide, not only the protein transduction domain can penetrate through cell membrane, but could maintain the activity of its fusion protein. Protein transduction is an emerging biology technology, it has been applied into all aspects of cell gene regulation since its invention. In this article, we take Tat, Pdx-1 and Beta/NeuroD for instance and review the application of transduction protein in the dif-ferentiation of pancreatic stem cell.

In this year,ASH annual meeting reported several new targeting therapeutic drugs for chronic lymphocytic leukemia (CLL) and a part of lymphoma.Those drugs focus on some key targets in the signal transductional pathway of B cells.Although these targeting drugs individually did not improve the complete remission rate of CLL,but several clinical trial results showed that the combination therapy of those drugs with other drugs significantly improved the efficacy of CLL,and prolonged the progression-free survival of CLL patients.Therefore,experts believe that combination therapy and sequential therapy will start a new era in the treatment of CLL.This paper will share only the latest advances in the treatment of CLL and parts of lymphoma with domestic readers.

In clinical nursing practice, ethnics dilemmas which nurses facing with are not usually a simple question of right and wrong or yes and no, but two or more mutual conflicts under some special circumstances; In order to help nurses to understand and deal with ethnics dilemmas effectively and reasonably, the authors summarize the four different ethnics dilemmas: the different ethical principles selection dilemma, the different stakeholder selection dilemma, the different interpersonal ethnics dilemmas and the conflict of the nursing professional ethics and the role morality. Typical cases of common ethnic dilemmas were summarized and analyzed in this paper.

Objective To examine the effect of lutein supplementation on visual function in people with long-term display light exposure. Method Thirty-seven persons (age 22-30) with long-term display light exposure were divided into low-dose group, high-dose group, and placebo group involving supplementation with 6 mg lutein/d, 12 mg lutein/d, and placebo for 12 w. The levels of serum lutein and visual function indices such as break-up time (BUT), critical flicker fusion frequency (CFF), visuognosis persistence, and reaction time were measured at week 0 and 12. Results After lutein supplementation serum concentrations of high-dose group and low-dose group increased from (0.328?0.120) ?mol/L to (0.733?0.354) ?mol/L, and from (0.356?0.117) ?mol/L to (0.607?0.176) ?mol/L respectively. There was significant increase of break up time in left eyes of high-dose group. Visuognosis persistence was significantly improved, and significant decrease of simple reaction time was observed in high-dose group. No statistical change was observed in critical flicker fusion frequency, discriminative reaction time and choice reaction time during the study. Conclusion Visual function indices such as break-up time, visuognosis persistence and simple reaction time in people with long-term display light exposure who received lutein supplements were significantly improved.

[Qbjective]To observe the effects of Zidian prescription extracted by two kinds of process on ITP mice.[Methods] Using APS to inject into mice to induce the ITP model.Mice were divided into 6 groups: C,M,DC,X,S and G groups.The number of platelet on 7th day and 14th day were measured in mice.Meanwhile the weight on 7th day and 14th day and the degree of subcutaneous bleeding were recorded.[Results]There is no significant difference in weight and the number of platelet in all groups before the experiment.Compared with the C group,the weight is in down trend in M group on 7th day,the weight and the number of platelet were declined in M group on 14th day,the petechia was more clearly in M group.Compared with the M group,the weight is up trend in DC,X,S and G groups on 7th day,the weight and the number of platelet are enhanced in DC,X,S and G groups on 14th day,the petechia was decreased in DC,S and G groups significantly.Compared with the DC group,the number of platelet is decreased in X,S and G groups.Compared with the X group,the number of platelet is increased in S and G groups.[Conclusion] Zidian prescription extracted by two kinds of extraction process has an remedial effect on ITP mouse.There is no significant difference between the two kinds of extraction process.
