Application of Seminar Teaching Method Combined with Case-Based Learning and Problem-Based Learning Teaching Models in Oral Clinical Nursing Teaching

Purpose:To analyze the role of the seminar teaching method+case-based learning(CBL)teaching method+problem-based learning(PBL)teaching method in oral clinical nursing teaching.Methods:13 undergraduate nursing students who entered the department from September 2020 to September 2021 were selected as the control group,adopting conventional nursing teaching methods;13 undergraduate nursing students who entered the department from September 2021 to August 2022 were selected as the observation group,adopting the seminar+CBL+PBL teaching method.The teaching effects were compared between the two groups.Results:All assessment scores of the observation group were higher than those of the control group;all teaching satisfaction levels were higher than those of the control group(P<0.05).Conclusion:Adopting the seminar+CBL+PBL teaching method during oral clinical nursing teaching can improve nursing students’assessment scores,strengthen their core competencies,and enhance teaching satisfaction.

Evaluation of Postoperative Psychological Distress and Its Driving Factors in Patients with Oral and Maxillofacial Malignant Tumors

Objective:To explore and analyze the evaluation and driving factors of postoperative psychological pain inpatients with oral and maxillofacial malignant tumors.Methods:Relevant data were collected from 80 patients with oral and maxillofacial malignant tumors who attended the outpatient clinic for follow-up consultations between May 2021 to May 2023.The patients used the psychological distress thermometer(DT)to circle words that best described their experiences in the past week,assigning a numerical value(0-10)to indicate their pain level on each day.The scoring results were employed to assess the psychological pain in these patients.A self-developed patient basic information questionnaire was utilized to record demographic details.Logistic regression analysis was employed to evaluate patients two weeks after surgery,focusing on the assessment of psychological distress and the identification and location of driving factors.Results:Following evaluation,the results revealed that the average postoperative DT score for the 80 patients with oral and maxillofacial malignant tumors was 4.53±1.98 points.Scores<4 points indicated no psychological pain(Group N)in 48 cases,while scores≥4 points indicated psychological pain(Group Y)in 32 cases.The differences in postoperative DT scores among patients with varying educational levels,fears and worries about disease progression,economic problems,sleep problems,level of hope,and oral pain were statistically significant(P<0.05).Multiple linear regression analysis results indicated that education level,fear and worry about disease progression,economic problems,sleep problems,level of hope,and oral pain are driving factors of postoperative psychological pain in patients with oral and maxillofacial malignant tumors(P<0.05).Conclusion:The postoperative psychological pain level in patients with oral and maxillofacial malignant tumors is at a moderate level.Educational level,fear and worry about disease progression,economic problems,sleep problems,level of hope,and oral pain were identified as driving factors for postoperative psychological pain in these patients.

Analysis of the Effect of Mindfulness Meditation on Patients with Burning Mouth Syndrome

Objective:To explore the effect of mindfulness meditation on patients with burning mouth syndrome.Methods:60 patients with burning mouth syndrome in our hospital who were treated from January 2021 to December 2022 were selected for this study.The patients were divided into two groups of thirty cases each using the randomized numerical table method.The observation underwent psychological intervention and mindfulness meditation training,while the control group only received symptomatic care.The condition of the patients of both groups was observed and compared.Results:Upon receiving treatment,the patients in the observation group had lower Hamilton Anxiety(HAM-A)scores,and Hamilton Depression(HAMD)scores compared to the control group(P<0.05).The visual analog scale(VAS)scores of the observation group were also lower than those of the control group(P<0.05).Moreover,the efficacy of the nursing intervention in the observation group was higher than that of the control group(P<0.05).Conclusion:Psychological intervention and mindfulness meditation training can effectively improve the clinical symptoms of patients with burning mouth syndrome.Therefore,this treatment method should be popularized.

Study on the Electric Actuation of Liquid Metal Column in Confining System

Research on micro-machines is becoming popular.In this paper,the electric driving behavior of liquid metal columns in confining channel was studied.When the electric field was applied,the liquid metal near the negative electrode became flat,longer.The NaOH electrolyte(1.0 mol/L)could flow from the positive electrode to the negative electrode from a small space above the liquid metal column.Besides,the length and volume of the liquid metal would affect its motion and deformation behavior.Both cylindrical liquid column(R=5 mm,L=5 cm)and linear liquid column(R=5 mm,L=40 cm)exhibit deformable movements,which are similar to the bionic movements of earthworms.The electrically driven liquid metal in closed systems could provide a theoretical basis for droplet actuation in microtubes.It has a very wide application prospect in the field of micro-drive machines.
