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.

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.

Spine metastasis stereotactic body radiation therapy delivers conformal high radiation dose to the tumor target, and steep falloff dose gradients protect adjacent normal structures, especially spinal cord. Some studies demonstrated stereotactic body radiation therapy for metastatic tumors of the spine is safe and clinically effective. This technique markedly improved local control with an excellent symptomatic response compared with conventional external beam radiation therapy techniques, and is beginning to change the treatment paradigms for metastatic spine disease both as post-operative adjuvant therapy and primary definitive local treatment. Although the technique is being increasingly used in clinical practice, the optimal fractionation schedule remains uncertain. Based on the research of radiobiologic principles, radiological physics and clinical data, multiple session stereotactic body radiation therapy has some advantage in clinic.

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 analyze the quality control of the conformal radiotherapy for nasopharyngeal carcinoma. Methods Using BJ-6 6MV linear accelerator, STAR -2000 3D TPS and immobilization device, the patient of nasopharyngeal carcinoma were treated by the conformal radiotherapy. Results Adopting individualized compatibly-shaped face masks and CT scanning (2mm interval, 2mm thickness), three dimensional data of the target and the other tissues were acquired. The conformal radiotherapy was designed in planning system. At the treatment, the target volume was put on the isocenter of the linear accelerator by the customized patient positioning. Conclusion Because the nasopharyngeal carcinoma is located in a special area and it is surrounded by some important organ, in the conformal radiotherapy, the quality control of the CT immobilization technique and the customized patient positioning is very important. This can ensure effective and safe irradiation for the small target volume while excessive irradiation is avoided in other surrounding organs.

Radiotherapy and chemotherapy are the main treatment means for locally advanced squamous cell carcinoma of the pharynx and larynx, to guarantee efficacy and avoid the damage of radical surgery, so as to preserve the laryngeal function of swallowing and pronunciation.With the progressing of radiotherapy technology,concept of treatment and radiotherapy mode have been advanced constantly,that have prolonged the survival time and improved the quality of life.This study will review the progress of radiotherapy in the pharynx and larynx squamous cell carcinoma, investigate the improvement of radiotherapy technology and hypofractionated IMRT, and provide reference for reducing the toxicity and after effects of radiotherapy.

Objective Sanatoriums have many complex business systems,so there is an urgent need for safe,reliable and stable operation of data centers to provide uninterrupted data services for its business systems. Methods Based on Web service heterogeneous system integration technology,data crawling robot technology,data center core technologies related to the data center,data center of sanatoriums was built. Results Sanatorim data center is the foundation on the integration platform of information,it is an effective solution to application integration and data sharing to achieve data consistency,timeliness,completeness,safety,effectiveness and accuracy. Conclusion The relative concentration of data center in the building of sanatorium is necessary in the development of sanatorium.
