Objective To perfect the prescription knowledge discovery methods; To discover the key factors affecting the robustness of prescription therapeutic model as well as improve its recognition capability.Methods Expanded knowledge base and improved design of Chinese Medicine Prescriptions Intelligence Analytic System (CPIAS) were proposed, such as the establishment of the heuristic filtering rules of efficacy-syndrome relationship, knowledge table of efficacy-syndrome element relationship, identification of efficacy-syndrome element relationship, and syndrome element-syndrome relationship. In addition, quantitative data were calculated by CPIAS. Prescription therapeutic modeling experiments on the Chinese medicine prescriptions system were conducted based on support vector machine (CPSVM), which was also used to analyze the learning outcomes.Results Using expanded knowledge base and improved calculation results can significantly promote learning abilities of CPSVM.Conclusion Screening of efficacies, sorting of symptoms, and collection of syndrome elements are the key factors affecting the quality of prescription therapeutic model.

Objective:To evaluate the practicability and effectiveness of nursing plan for elderly patients with urinary incontinence after operation.Methods:The patients admitted to the Department of Urology and Gynecology in a Grade 3A general hospital from September to October 2019 were selected as the control group, and the patients admitted from December 2019 to January 2020 as the intervention group. In the quasi-experimental study, the control group was given routine discharge guidance, and the intervention group was given a nursing plan for elderly patients with urinary incontinence to observe the preliminary effect of the nursing program for a period of 2 months.Results:Two months after implementation, the total scores of discharge preparation, quality of life and satisfaction of urinary incontinence in the intervention group was (125.08 ±17.64), (58.79 ±5.52) and (96.09 ±2.53) respectively, which were significantly different from those in the control group ( P<0.05). Conclusion:The preliminary verification of the scheme has a certain feasibility, has a certain guiding significance for nurses, and is helpful to improve the discharge preparation of elderly surgical patients with urinary incontinence and improve their satisfaction and quality of life when they are discharged.

Objective:To search, evaluate and integrate the best evidence of exercise rehabilitation intervention after PCI in patients with acute myocardial infarction, so as to provide evidence-based basis for clinical doctors and nurses to intervene in exercise rehabilitation of patients.Methods:We searched PubMed, China National Knowledge Infrastructure, Wanfang Data and other domestic and foreign databases, guide websites and professional association websites about the evidence of exercise rehabilitation intervention in patients with acute myocardial infarction after PCI. The search period is from January 2010 to June 2021. The quality of the included literature was evaluated by two researchers, and the literature evidence in accordance with the quality standard was extracted.Results:A total of 20 articles were included, and 39 pieces of evidence were summarized from 11 aspects, such as the establishment of multidisciplinary team, evaluation, exercise prescription, exercise monitoring and so on.Conclusions:This study summarized the best evidence of exercise rehabilitation intervention in patients with acute myocardial infarction after PCI, and provided theoretical support for clinical practice. It is suggested to combine the clinical situation and patients' wishes to promote the transformation of the best evidence to clinical practice.
