Effects of reflective learning based on visual mind mapping in the fundamentals of nursing course: A quasi-experimental study.

BACKGROUND: Previous studies have shown that reflective learning and mind mapping have many advantages in nursing education, but the relevant researches on the joint application of the two strategies are very limited. OBJECTIVES: To confirm the efficacy of reflective learning based on visual mind mapping for educational purposes to support the critical thinking, academic self-efficacy, and professional self-concept of nursing students. DESIGN: A quasi-experimental design with pretest and posttest model. SETTINGS: A nursing college in Chengdu, Sichuan Province, China. PARTICIPANTS: Eighty 2nd year baccalaureate nursing students in two parallel classes were assigned to an intervention group (n = 40) and a control group (n = 40) with one class for each group. METHODS: This study was carried out from September 15 to November 30, 2021. The Chinese version of Critical Thinking Disposition Inventory (CTDI-CV), the Chinese version of Academic Self-Efficacy Scale (ASE-CV), and the Chinese version of Professional Self-Concept of Nurses Instrument (PSCNI-CV) were used to evaluate the effects of the study intervention on nursing students. Firstly, the pretest data were collected from students in the two groups. Then, the intervention group students made regular reflective entries based on mind mapping and the control group students conducted traditional reflective journal, while attending routine educational and clinical activities, about their experiences of the Fundamentals of Nursing course learning process. After the intervention, both groups completed the three scale tests again, and an open-ended question was set for intervention group to explore the difficulties or challenges encountered by students. Descriptive statistics, Chi-square, Mann-Whitney U test, and content analysis were performed. RESULTS: There were no significant baseline demographic variables differences between the two groups. The intervention group showed significant improvement in critical thinking (P = 0.000), including truth-seeking, open-mindedness, analyticity, systematization, and inquisitiveness sub-dimensions (P = 0.000-0.014), and professional self-concept (P = 0.015), including flexibility and satisfaction sub-dimensions (P = 0.015-0.039), as compared to the baseline. There was no significant difference in students' academic self-efficacy level between pretest and posttest of the two groups. Compared to the total level of critical thinking between the intervention and the control group, the difference median values (posttest score-pretest score) were 14.0 and 1.5 respectively; and for professional self-concept, were 4.5 and 0.5 respectively, which were statistically significant at P < 0.05 level (P = 0.001-0.020). According to open-ended question survey, difficulties or challenges faced by the intervention group students were mainly problem of charting mind mapping, unfamiliar with tools, problem of mentors' guidance, and time-consuming. CONCLUSIONS: This study found that it is appropriate for students to adopt reflective learning based on visual mind mapping. Although there were no significant differences in the improvement level of students' academic self-efficacy, students' critical thinking and professional self-concept were greatly improved by the intervention. This approach may be used as a complementary learning method for baccalaureate nursing education.

Association between CT imaging features and KIT mutations in small intestinal gastrointestinal stromal tumors.

Small intestinal gastrointestinal stromal tumors (GISTs) have different clinical outcomes when KIT mutations are in exons 11 or 9, which are also the most common sites of neoplastic KIT mutations. The purpose of this study is to evaluate the CT imaging features in those two groups. A total of 35 patients were enrolled, and both quantitative and qualitative CT imaging features were compared between patient groups with KIT exon 9 mutations (KIT-9) and exon 11 mutations (KIT-11). The KIT-9 group was statistically associated with a tumor size larger than 10 cm and a higher enhancement ratio when compared with those of the KIT-11 group (both P < 0.05). For the enhancement ratio, the receiver operating characteristic curve indicated a cut-off value of 1.60 to differentiate KIT-9 from KIT-11 tumors. Additionally, tumor necrosis was more commonly seen in the KIT-9 group. In multivariate analysis, tumor size (ß = 0.206; P = 0.022) and KIT-9 (ß = 0.389; P = 0.006) were independent factors associated with tumor necrosis. Taken together, KIT-9 mutant tumors tended to have CT imaging features indicative of more aggressive neoplasms. These findings may be helpful in identifying more aggressive small intestinal GISTs and optimizing treatment.

[Interleukin-10-1082 promoter polymorphism and the risk of gastric cancer].

OBJECTIVE: To investigate the association between Interleukin-10 (IL-10) promoter polymorphism and the gastric cancer risk in Chinese Han patients. METHODS: DNA was extracted from blood samples of gastric cancer patients (n = 75) and controls (n = 75). IL-10 -1082 promoter polymorphism in both patient and control group (three genotypes distribution: AA, AG and GG) was identified by PCR-RFLP and its relationship with gastric cancer risk, clinic and pathologic features was also analyzed. RESULTS: Patients with gastric cancer had a significantly lower frequency of AA (OR = 0.43, 95% CI = 0.20, 0.92; P = 0.03) than controls. Patients with proximal gastric cancer had a significantly higher frequency of GG (OR = 3.06, 95% CI = 1.12, 8.36; P = 0.03) than those with distant gastric cancer. Patients with advanced (stage II/IV) gastric cancer had a significantly higher frequency of AA (OR = 5.09, 95% CI = 1.05, 24.70; P = 0.04) than those with early (stage I /IV) gastric cancer. When stratified by the Lauren's classification, histological differentiation of gastric cancer, no statistically significant results was observed. CONCLUSION: This study suggests that the IL-1 1082 promoter polymorphism may be associated with gastric cancer in Chinese Han patients, and the difference in genotype distribution may be associated with the location and stage of gastric cancer.

[Pathogenesis and clinical significance of interleukin-8 and tumor necrosis factor-alpha in cervicitis].

OBJECTIVE: To investigate the relationship between local immune status of vagina and the occurrence of disease in patients with cervicitis. METHODS: ELISA were used to detect the level of interleukin (IL)-8 and tumor necrosis factor (TNF)alpha in vaginal douche of patients with cervicitis due to ureaplasma urealyticum, mycoplasma hominis, chlamydia trachomatis, neisseria gonorrhoeae and cervical erosion. RESULTS: Compared with the control group, the level of IL-8 in vaginal douche of patients with mycoplasma hominis cervicitis, chlamydia trachomatis cervicitis and neisseria gonorrhoeae cervicitis was significantly higher and there was significant difference ng/L: 371 +/- 34, 369 +/- 31, 339 +/- 36, vs 341 +/- 32, 338 +/- 33, 316 +/- 24, (all P < 0.01). Comparing the level of IL-8 in vaginal douche of patients with ureaplasma urealyticum cervicitis and cervical erosion with that of control group, there was no statistical difference (all P > 0.05). The level of TNF-alpha in vaginal douche of each group was remarkably higher than that of control group except for patients with cervical erosion. And statistically significant difference was found between them (all P < 0.01). CONCLUSION: With regards to the pathogenesis of cervicitis, local immune mechanism of vagina plays an important role in the occurrence of cervicitis. The role of IL-8 in pathogenesis of mycoplasma hominis cervicitis, chlamydia trachomatis cervicitis and neisseria gonorrhoeae cervicitis is likely to be more important.
