Objective: The goal of this research was to explore the relationship among attachment to parents,perceived academic achievement and self-esteem in high school students. Methods: High school students from four areas completed the following four questionnaires: Relationship Questionnaire(RQ),Experiences in Close Relationships Inventory(ECR),Self-esteem(SES) and Perceived Academic Achievement. Results: ①The scores of perceived academic achievement in students with attachment preoccupied to father were significantly lower than those with attachment dismissed to father. ②Attachment avoidance to father,attachment anxiety to father and self-esteem were positive correlated to perceived academic achievement (r=0.195,0.166 and 0.325). ③Attachment avoidance could predict the scores of perceived academic achievement. Conclusion: There are close relationship between adult attachment to father and perceived academic achievement,and self-esteem.

Objective To analyze diagnostic value of 18F-fluorode-oxyglucose(18F-FDG)positron emission tomography and computed tomography(PET/CT)in elderly patients with colon cancer.Methods A total of 102 patients with colon cancer admitted to Jingdezhen Hospital of Traditional Chinese Medicine from January 2021 to December 2022 were retrospectively selected to analyze the relationship between 18F-FDG PET/CT imaging and clinical features and its diagnostic value.Results The typical 18F-FDG PET/CT imaging of colon cancer was mainly concentrated in ascending colon,transverse colon,descending colon,and sigmoid colon.The glucose metabolism of each part increased,the intestinal wall thickened,and standardized uptake value(SUV)increased.There were statistically significant differences in SUV among colon cancer patients with different vertical thickness of the lesion,gender and lymph node metastasis(P<0.05).SUV was positively correlated with vertical thickness of the lesion and lymph node metastasis(P<0.05).Receiver operating characteristic curve results showed that the area under the curve of 18F-FDG PET/CT for diagnosis of colon cancer lymph node metastasis was 0.993,the sensitivity was 97.2%,and the specificity was 100%.Conclusion 18F-FDG PET/CT for the diagnosis of elderly patients with colon cancer has a high clinical application value.
