壳聚糖与乙醇用于舒乳消痛口服液澄清工艺的比较 总被引:10,自引:1,他引:10
目的:探讨壳聚糖絮凝法代替醇沉用于舒乳消痛口服液澄清工艺的可行性。方法:壳聚糖用于舒乳消痛口服液的澄清,通过对总固型物、正丁醇浸出物、芍药苷含量的测定,对壳聚糖的用量、药液的密度进行了优选,并与醇沉工艺进行了比较。结果:壳聚糖絮凝法与醇沉法同样能使药液澄清,在总体有效成份的保留上,前者优于后者,但皂苷成份的保留量后者略大于前者。结论:壳聚糖絮凝法能代替醇沉用于舒乳消痛口服液的澄清工艺,缩短生产周期,降低成本,但成份的微小差异对临床治疗的影响尚待进一步的探讨。 相似文献

芍丹乙肝口服液澄清工艺的研究 总被引:2,自引:0,他引:2
目的优选芍丹乙肝口服液的澄清工艺。方法通过对水浸出物收率、总多糖含量及芍药苷含量的测定,比较了乙醇沉淀法、高速离心法、吸附澄清技术3种澄清工艺的差异。结果3种澄清工艺对3个指标均有不同程度的影响,其中吸附澄清技术能使水浸出物收率降至18%左右,有效成分保留率在80%以上,且溶液澄清。结论吸附澄清技术可作为芍丹乙肝口服液的澄清工艺, 相似文献

ObjectiveTo assess intervention feasibility and acceptability, and compare the effectiveness of the CHOICES Decision Aid (DA) versus the National Cancer Institute (NCI) Cancer Clinical Trials (CCT) website to improve knowledge about CCTs and preparedness to make an informed decision.MethodsOncology patients (n = 101) with a scheduled clinic visit were enrolled and randomized. Decision-making variables were collected at two timepoints. Post-intervention scores were examined via paired t-tests and multivariate regression analyses. Predictors of the magnitudes of the change in scores were examined in multivariable regression analyses.ResultsThe interventions were feasible to implement and acceptable to participants. Both interventions increased objective and subjective knowledge, improved clarity of opinions, and reduced decisional conflict (p-values < 0.01). Improvements in the belief that one could find out about CCTs were observed in the CHOICES DA arm (p < 0.001). Multivariable analyses controlling for educational attainment showed no significant differences in the magnitude of change in outcome variables between intervention arms, but did find that improvements in some variables in the NCI arm – but not CHOICES DA arm – were associated with previous educational attainment.ConclusionsInterventions were feasible to implement and acceptable. Improvements in knowledge and decision-making outcomes were observed in both arms, supporting the view that interventions to improve CCT decision making are effective and feasible. Our results suggest that the CHOICES DA may be more effective than an informational website in improving decision-making outcomes regardless of participants’ educational attainment.Practice implicationsCCT resources should support informed decision-making among all cancer survivors, regardless of educational attainment. 相似文献

Objective
To review the strengths and weaknesses of deliberative and intuitive processes in the context of patient decision support and to discuss implications for decision aid (DA) design.Methods
Conceptual review of the strengths and weaknesses of intuitive and analytical decision making and applying these findings to the practice of DA design.Results
DAs combine several important goals: providing information, helping to clarify treatment related values, supporting preference construction processes, and facilitating more active engagement in decision making. Many DAs encourage patients to approach a decision analytically, without solid theoretical or empirical grounding for this approach. Existing research in other domains suggests that both intuition and deliberation may support decision making. We discuss implications for patient decision support and challenge researchers to determine when combining these processes leads to better outcomes.Conclusions
Intuitive and analytical decision processes may have complementary effects in achieving the desired outcomes of patient decision support.Practice implications
DA developers should be aware that tools solely targeted at supporting deliberation may limit DA effectiveness and harm preference construction processes. Patients may be better served by combined strategies that draw on the strengths and minimize the weaknesses of both deliberative and intuitive processes. 相似文献8.

An unplanned pregnancy is a crisis in a woman's life. She may request assistance from the health care provider in reviewing her options of becoming a parent, continuing the pregnancy and placing her baby for adoption, or terminating the pregnancy. To facilitate the decision-making process for women facing these choices, the clinician must first examine her own values and biases. To aid the clinician in providing nonjudgmental and nondirective counseling, this article provides factual information about abortion and adoption, values clarification exercises, and concrete approaches to help women examine their beliefs. 相似文献

AIMS: This paper seeks to remove some of the ambiguity surrounding the conceptual meaning of creativity using techniques of concept refinement to advance the concept. BACKGROUND: Creativity is an essential component of nursing practice that occurs daily in nurse's interactions with clients, families and other nurses. Failure to acknowledge and encourage creativity in beginning nurses may hinder future development and innovations in nursing practice and in nursing science. In order to promote the development of creativity it is first necessary to clarify and refine the concept as it applies to nursing. DESIGN/METHODS: A comprehensive review of a variety of computer and online databases resulted in thousands of articles on creativity between the years 1966 and 1999. The final sample (n = 48) was obtained using both stratified random and purposive sampling techniques. A content analysis of the literature was conducted using methods identified by Morse and illustrated in the work of Hupcey et al. Having determined the concept to be partially mature, the concept was advanced using techniques of concept refinement. FINDINGS: Content analysis of the literature yielded three differing definitions for creativity: revelation, birth and reincarnation. Creativity occurs in the presence of intrinsic motivation and a nurturing environment. While value is often used to identify whether a product is creative, the value of the product cannot determine whether the process has occurred. The product produced determines evidence of the process of creativity. LIMITATIONS: Limitations of this investigation are the use of secondary sources and the relatively small sample size (n = 48). CONCLUSIONS: Refinement of the concept of creativity indicates that it is a process that may be developed and influenced by the environment and is recognized by the product produced. Further investigation is needed to explore methods and techniques for developing creativity in nursing. 相似文献
