RESUMEN
Zebrafish (Danio rerio) is a simple biological labora-tory animal, with similar biological structure and physiological functions to mammals. Almost transparent embryos, in vitro de-velopment of embryos and up to 87% of human genetic similari- ties enable a wide application of zebrafish in the field of pharma-ceutical research. In this paper, we have studied the application of zebrafish in drug metabolism, the research of Chinese medi-cine, the evaluation of drug toxicology and safety, the screening of drugs and the discovery of new drugs, the research of regener- ative drugs, so as to provide new ideas of zebrafish in the field of pharmacy.
RESUMEN
Objective To explore the effect of preoperative evaluation checklist in the preoperative preparation of laparoscop‐ic cholecystectomy .Methods Based on whether the preoperative evaluation checklist was used or not ,664 cases of patients were di‐vided into control group (n=350) and experimental group (n=314) .Routine preparation was used in the control group ,while the preoperative evaluation checklist made by department of hepatobiliary surgery in the second affiliated hospital of Chongqing medical university was added to the experimental group .The case histories of patients in both groups were retrospectively reviewed ,so as to make comparisons of the defect of preoperative preparation ,influence to operation (delay or cancel) ,comprehension of preoperative knowledge ,and score of degree of satisfaction .Results The incidence rate of the defect of preoperative preparation in the experi‐mental group (1 .59% ) was lower than that in the control group (6 .86% ) with a statistical difference (P<0 .05) .The influence to operation (delay or cancel) in the experimental group was lower than that in the control group with a statistical difference (P<0 .05) .The comprehension of preoperative knowledge and score of degree of satisfaction in the experimental groups were obviously superior to those in the control groups ,which both had a statistical difference (P<0 .05) .Conclusion The application of preopera‐tive evaluation checklist in laparoscopic cholecystectomy could benefit for sufficient preoperative preparation ,conducting surgery as scheduled ,patients′comprehension of preoperative knowledge and patients′satisfaction of medical treatment ,which deserved widely clinical generalization .
RESUMEN
In view of the clinical graduate students' problems existing in the teaching of evidence-based medicine, such as having little knowledge of the course, lack of interest, not knowing how to retrieve, evaluate evidence and effectively use evidence, Xinjiang Medical University has car-ried on the reform in the curriculum content, teaching process, evaluation content and method of the teaching of EBM for the clinical graduate students. Practice shows that the clinical graduate students have significant improvement in objective examination average score, subjective examination average grades, total score and the students' satisfaction of the classroom teaching, and at the same time their interest in EBM courses and clinical thinking have also improved.
RESUMEN
Tumor metastasis is one of the most important biologi-cal characteristics of malignant tumor, and it is also the main factors that cause treatment failure and poor prognosis. Clinical studies have shown that the number of platelets in patients with malignant tumor increased more significantly than that in benign tumor patients and healthy people, which indicate that platelet might be involved in the development process of tumor. Further study found that in the process of cancer spreading to blood, platelet could interact with tumor cells to form tumor emboli, helped tumor cells escape from immune surveillance, thus pro-moted the tumor metastasis. In recent years, related mechanisms on platelets in promoting tumor metastasis were revealed gradual-ly, and several targeted therapies based on platelets were also carried out. This paper reviews the role of platelet in mediating tumor metastasis by hematogenous spread and its mechanisms and discusses the therapy strategies that target platelet, which may provide references for follow-up research and clinical treat-ment.
RESUMEN
The traditional ways of doctor -patient communication , are limited by the communication time and scope , both of them have been unable to meet the patients'communication needs .With the continuous development of network , social media extends the application scope in the field of healthcare .The application of social media in doctor-patient communication has some applicability and feasibility .This paper analyzes the limitations of tradi-tional doctor-patient communication , tries to apply the experience of social media in the field of healthcare , and puts forward some new application strategies:push information initiatively and enhance the doctor -patient interac-tion;carry out pre-hospital and aftercare communication to extend communication scope; collect feedbacks from patients and handle patients'complaints.
