RESUMEN
Objective To explore the effect of teaching mode based on ICARE on the professional spirit attitude of intravenous therapy specialist nurses.Methods 100 specialized intravenous therapy nurses who were trained in the Fourth Affiliated Hospital of Harbin Medical University from October 2021 to October 2022 were randomly divided into control group and experimental group.The control group students completed the training with traditional methods,while the experimental group students completed the training with the guidance of ICARE.Before and after the training,the professional spirit and attitude of the two groups of students was evaluated.Results After the implementation of the study,it was verified through independent sample r-test that the public services,autonomy and nurse job satisfaction of professional spirit and attitude scores group students was significantly higher than that of the control group(P＜0.05),and the difference was statistically significant.The Chi-squared test verified that the total incidence of complications of intravenous catheterization in the experimental group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).Conclusion The teaching mode based on ICARE can significantly improve the professional spirit and attitude of the intravenous treatment specialist nurses and the quality of intravenous infusion treatment.
RESUMEN
This paper expounds that the construction of a clinical teacher's teaching ability model is an urgent problem to be solved in medical colleges and universities, and analyzes that the current clinical teaching concepts and methods are constantly improving, and the clinical teaching environment is more informatized and intelligent. This paper summarizes the clinical teachers' teaching ability models at home and abroad, such as the ability and quality iceberg model, teacher growth model, inquiry-based teaching model, Molenaar three-dimensional teaching ability model, etc., and discusses the practice research progress of current clinical teacher teaching ability models such as student-centered guided teaching, bedside teaching, micro-teaching and BOPPPS (bridge-in, objective, pre-assessment, participatory-learning, post-assessment, and summary) method, medical simulation teaching, etc., hoping to provide guidance for further constructing models of teacher's teaching ability suitable for Chinese medical colleges and universities.
RESUMEN
Objective:Based on the current medical environment, to learn about cognition status of doctor-patient relationship among medical students and analyze causes of the tension between doctors and patients.Methods:Using the self-designed questionnaire "Clinical Medical Students' Cognition Survey on Occupational Status and Doctor-Patient Relationship", a cross-sectional survey was conducted on 527 medical students from 5-year and 7-year clinical program in Batch 2014 in a medical university in Heilongjiang Province. The survey mainly analyzed the causes of the tension between doctors and patients from the level of medical staff, patients and their families, hospitals and society. SPSS 22.0 was used for descriptive statistics and chi-square test.Results:The results showed that 93.7% of the medical students believed that the current doctor-patient relationship was not harmonious. There were cognitive differences among medical students in different gender ( P=0.029), first contact clinical grade ( P=0.003) and professional identity ( P<0.001). Conclusion:Medical students have a poor evaluation towards the current doctor-patient relationship. In order to construct harmonious doctor-patient relationship in the future, we can try to take measures such as carrying out relevant courses of doctor-patient communication, improving the medical students' communication skills and enhancing their professional identity.
RESUMEN
Objective To explore the clinical treatment effect of gastrointestinal tumor surgery. Methods Eighty patients with gastrointestinal tumor treated in our hospital from May 2010 to December 2014 were selected and evenly divided into the observation group (n=40) and the control group (n=40). The observation group was given laparoscopic surgery treatment while the control group was given conventional laparotomic surgery treatment. The treatment effects, recurrence situation, second surgery situation, quality of life scores and other indicators of the two groups were com-pared. Results The treatment effect of the observation group was significantly higher than that of the control group(P<0.05). The recurrence rate, second surgery and healing situation of the the observation group was also significantly higher than the control group(P<0.05). The qualify of life score of the observation group was significantly better than that of the control group, with significant difference(P<0.05). Conclusion In the treatment of patients with gastrointestinal tumor, the application of laparoscopic surgery treatment can effectively improve the treatment effect, reduce the sec-ondary damage to patients and enable total resection of hidden tumors, which improves the patients' health degree as well as their quality of life.
RESUMEN
Objective To determine the length of warm ischemic (WI) tolerance in bronchial graft from non-heart-beating donors. Methods Forty-eight rats were randomly divided into 4 groups (each group having 12 rats) according to different WI durations including WI-0 min (group A), WI-30 min (group B), WI-45 min (group C) and WI-60 min (group D). In each group, the tracheae from 6 rats were respectively imbedded in greater omentum of other 6 rats, and 14 days later, the transplanted tracheae were taken from recipients to evaluate epithelial thickness and regeneration. Results Epithelial thickness and the degree of epithelial regeneration had no significant difference (P >0. 05) between the syngeneic control group and the WI-30 minutes group. All of the grafts with WI duration of 45 min were viable, but the epithelium was significantly thinner than that in the syngeneic control group (P<0. 05). However all of the grafts with WI duration of 60 min showed lower viability rate. Conclusion The time limits of tolerance to WI of tracheal grafts from NHBDs may be 45 min.
RESUMEN
Objective To observe the ultrastructure and absorption function of colon mucosa in rat with ultra-short bowel syndrome. Methods Totally 30 SD rats were randomly divided into three groups: ultra-short bowel group (90%-95% of the intestine was surgically resected, n = 10), sham group (n = 10), and normal control group (n = 10). All animals were given with enteral nutrition. Scanning electron microscopy was performed 21 days later to observe the morphology of mucosal surface, and transmission electron microscopy was performed to observe the ultrastructural changes of intestinal epithelial cells. The absorption of colon to water, carbohydrates, and amino acid determined after 3 hours of closed perfusion of the colon with D-xylose solution and 15N-glycine on the continuous cycle of colon. Results As shown by the transmission electron microscopy, compared with the normal control group, rats in the ultra-short bowel group showed significantly decreased goblet cells on colonic mucosl surface, increased epithelial cells, longer and denser microvillus, increased area of membrane surface, increased number of cell-cell junctions, increased number of desmosome, tight junction, and gap junctions, higher development of endoplasmic reticulum and dictyosome, and increased number of mitochondria. As shown in the screening electron microscopy, compared with the normal rats, rats in the ultra-short bowl group had significantly deeper colon folds, thicker mucous membrane, increased number of bay openings, and longer and denser microvillus-like structures inside bays. The capability of water absorption was signicatnly higher in the ultra-short bowl group than in the sham group and normal control group (P = 0. 000) . The absorption rates of xylose and 15 N-glycine were also significantly higher in the ultra-short bowl group than in the control group (P ＜ 0. 01). Conclusions The absorption capability can be compensatively increased in rats with ultra-short bowel syndrome. Decreased apoptosis of colon mucosa cells, increased absorption cells, hyperplasia of microvilli, increased area of the membrane surface,and increased number of mitochondria may constitute its material and energy bases.
