ABSTRACT
Objective:To understand and explore the psychological experience of standardized patients, in order to provide an effective basis for training and applying standardized patients.Methods:The phenomenological methodology in qualitative research was used in the study, and the Colaizzi 7-step data analysis method was used for analysis the interview recording.Results:The psychological experience of standardized patients can be summarized into three themes: understanding of pressure from medical staffs, the desire for balance the effort and harvest, challenge and growth.Conclusions:Medical staffs need to considere the psychological experience of standardized patients in the training and application, pay more attention to their psychological changes and provide corresponding work and emotional support.
ABSTRACT
Objective To throagh observing the change of plasma D-Dimer level in the acute cerebral infarction patients to provide the experimental foundation for further research of pathology,physiology pathological process judgment and observation of curative effect.Methods To measure the plasma D-Dimer level by ELISA in 71 cases of acute wrebral infarction patients and 64 healthy controls.Results The plasma D-Dimer level in the acute cerebral infarction patients in acute period was 72h(1.54 ±0.91)mg/L、7d(1.32 ±0.86)mg/L significantly higher than 15d (0.49±0.31)mg/L30d(0.32±0.14)mg/L at resume period patients and(0.31 ±0.81)mg/L at normal controls and dropped in resume period(t =2.576,t =2.807,P＜0.01).They had significant difference.Conclusion The results indicate that acute cerebral infarction is in the manifestation of hyper coagulation,plasma D-Dimer measuring was valuable for pathological process judgment and observation of curative effect of acute cerebral infarction.
ABSTRACT
Objective To analyze and summarize the clinical characteristics and to evaluate the laboratory tests and therapeutic methods of pancreatic carcinoma,so as to improve the understanding pancreatic carcinoma.MethodsThree hundreds cases of pancreatic carcinoma were collected during 1995—2003 in PUMCH.Results ①The clinical systoms included weight loss(75.3%),abdominal pain(66.3%),anorexia(51.0%),jaundice(50.0%),abdominal distention(44.0%),back pain(18.0%),diarrhea(14.3%) and melena(7.7%).②The sensitivities of tumor markers to diagnose pancreatic cancer were 77.5% of CA19-9,66.0% of CA50,48.3% of CA242 and 29.7% of CEA.If CA19-9 combined with CA50,CA242 and CEA,its sensitivity was increased up to 86.0%.③The titer value of CA19-9 was significantly related with radical operation ratio(P
