ABSTRACT
Objective:To explore the application effect of the auxiliary teaching mode based on WeChat Official Platform in pathology teaching.Methods:With the help of WeChat Official Platform, the "Pathology Experimental Course Platform of Qiqihar Medical University" (bilingual) was designed and formed. For the international students in the experimental group, teachers designed, developed and generated teaching resources in advance according to the requirements of pathology syllabus for international students and teaching contents, and post them on the platform. At the end of the term, they had pathology examination with the same difficulty as the control group, and their results were comparatively analyzed. Meanwhile, a questionnaire survey was designated to evaluate the teaching process and effects, to find out whether the platform work for the students to obtain more extracurricular knowledge and improve learning efficiency. SPSS 19.0 was used for t test. Results:Compared with the control group [(7.56±0.12) points and (53.20±0.70) points], the experimental group's scores of experimental assessment [(8.59±0.13) points] increased significantly ( P<0.05), and the scores of theoretical assessment [(56.23±0.60) points] also increased significantly ( P<0.05). Conclusion:With the help of the WeChat Official Platform, the auxiliary teaching mode breaks the limitation of time and space, enables foreign students to study and observe more actively, consolidates basic theoretical knowledge, strengthens the ability to observe disease lesions and clinical thinking ability, promotes international students' understanding of the relationship between pathological changes and clinical symptoms and signs, and improves their academic performances.
ABSTRACT
Objective:To investigate the "V" -shaped anatomical approach in the prevention of bile duct injury during laparoscopic complex cholecystectomy and its clinical application value.Methods:The patients with complex gallbladder from June 2020 to June 2021 in the First Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology were selected as the research objects, and they were randomly divided into observation group and control group, with 60 cases in each group. All patients underwent laparoscopic cholecystectomy. The observation group underwent laparoscopic cholecystectomy through the triangle "V" shape of the gallbladder, and the control group did not use the "V" shape anatomy. The operation status, complications and postoperative recovery of the two groups of patients were compared.The measurement data of normal distribution were expressed by ( Mean± SD), and t test was used for comparison between groups, and chi-square test was used for comparison between groups of count data. Results:The conversion rate to laparotomy, intraoperative bleeding and operation time of observation group were 3.33%, (97.31±13.27) mL, (65.27±13.82) min, which were significantly lower than those in the control group[8.33%, (111.27±25.18) mL, (81.35±12.12) min], the differences between the two groups were statistically significant( P<0.05). The incidence of biliary injury, total incidence of complications of the observation group were 0, 8.33%, which were significantly lower than those in the control group(6.67%, 28.33%), the differences between the two groups were statistically significant( P<0.05). The postoperative exhaust time, drainage tube retention time, hospitalization cost and hospitalization time of the observation group were (9.89±3.58) h, (32.58±5.17) h, (3 142.92±137.93) yuan, (4.73±1.42) d, and significantly lower than those in the control group [(11.65±2.45) h, (46.18±6.49) h, (3 424.29±156.34) yuan, (5.38±1.25) d], the differences between the two groups were statistically significant ( P<0.05). Conclusions:For laparoscopic complex cholecystectomy, the use of the triangular "V" -shaped gallbladder anatomical approach is more conducive to the operation, can reduce the patient's operation time and intraoperative blood loss, reduce the rate of intraoperative conversion to laparotomy, and reduce biliary tract injury and bile leakage. Such as the incidence of complications, prompting patients to recover as soon as possible, it is worthy of clinical application and promotion.
ABSTRACT
In order to explore the application of the teaching mode based on WeChat official platform in the teaching of experimental pathology for international students, the students are required to browse the teaching objectives and the general pictures and microscopic pictures of experimental specimens on the public platform before the experimental class, and get in touch with the preliminary diagnosis of pathology at an early stage, contact with the preliminary diagnosis of pathology early, and consolidate and expand their knowledge after class by using the platform. The research shows that the mixed teaching mode based on the official platform can improve the diagnostic thinking of foreign students in pathology, deepen their understanding of pathology, increase the interaction between teachers and students and the supervision of teachers on students, and enhance their interest in learning.
ABSTRACT
Objective To explore the advantages and characteristics of pathology experimental teaching based on WeChat public platform. Method Through the establishment ofhomogeneous pathol-ogy experiment platform—WeChat public platform, the students of clinical medicine major of Class 1 and 2 of Grade 2014 who participated in the pathological experiment course were divided into two groups. The experimental group (65 people) used the auxiliary teaching based on the WeChat public platform, and the control group (65 people) used the traditional teaching method. The students in the experimental group used the WeChat public platform in combination with pathology experimental teaching, pushing the experimental teaching by WeChat public platform, including the change of specimen and eye diseases under the micro-scope of typical pictures and videos, and at the same time pushing the typical disease image and the related text introduction, and auxiliary pathology experimental teaching. The effect of teaching was evaluated by student experimental examination and electronic questionnaire. The data were collated after the entry of SPSS 19.0, and the data comparison was performed by t test. Result The average score of the experimental group (14.80±0.24) was significantly higher than that of the traditional teaching group (13.79±0.33), and the difference was statistically significant (P=0.031). The experimental group students' evaluation on the learning of WeChat based public platform was higher than the control group's evaluation on traditional teaching in the aspects of learning interest, reducing learning pressure and feedback. Conclusion The application of WeChat public platform for the teaching of pathological experiments is feasible compared with the traditional teaching model and can improve the teaching effect effectively, and solve the problems of the pathology experiment teaching sample being insufficient or the teaching sample being not typical, which creates conditions for students to study independently and use specimens and pictures.
