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.

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.

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 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.

Acute myeloid leukemia (AML) is the major topic in American Society Hematology (ASH)Annual Meeting and Exposition. There were 887 scientific articles on AML in the 53rd ASH Annual Meeting and Exposition in 2011,in which many studies focused on clinics.Here is introduction of o.ptimized regimens for AML and elderly AML,as well as targeted therapy for AML presented in the meeting.

Acute myeloid leukemia (AML) is the most commom hematologic malignancy in adults.There are so many highlights in the 54th ASH annual meeting in the field of mechanism,diagnosis and treatment of AML.Especially many studies have identified genes close related to AML development,clones related to relapse and molecular marker for prognosis using next-generation sequencing (NGS).Minimal residual disease (MRD) assay has been used for evaluation of therapy efficacy and posttherapy prognostication in AML treatment.The tyrosine kinase inhibitor targeting FLT3-ITD in this meeting is the best highlight in the treatment of refractory and relapsed AML.

Congenital adrenal hyperplasia (CAH) owing to steroid 21-hydroxylase deficiency (21-OHD) was a relatively frequent of autosomal recessive disorders characterized by the inactivation of the steroid-synthesizing enzyme in the adrenocortex.Corticosteroids (glucocorticoids and mineralocorticoid) replacement therapy was the primary treatment of 21-OHD.The main objective of 21-OHD treatment in children was to maintain normal growth.Inadequate or excessive treatment was commonly observed.A number of studies reported that 21-OHD adult were at increasing risk of developing metabolic syndrome and cardiovascular events.However,there was few researches on 21-OHD children with metabolic disorders,and no domestic reports.The article summarized recent clinical research progresses in research on the alterations of lipid and carbohydrate metabolism in children with classic 21-OHD.

While only in minute quantities in the body, trace elements are crucial co-factors and regulators of normal metabolism.Commonly tested elements include calcium, magnesium, iron, zinc, and copper.Imbalance or deficiencies in trace elements can cause growth retardation, malnutrition, immune malfunction and other abnormalities in children.Because these elements are in trace amounts, sensitivity and reproducibility of detection methods are of paramount importance.Different methods for the same element can yield different reference intervals, which, in order to be applied in the clinic, would have to be independently established by individual laboratories.Clearly defined indications and good quality control to ensure accuracy and sensitivity are necessary for the measurement of trace elements to provide objective reference for clinical diagnosis.
