Three-dimensional printing for preoperative rehearsal and intraoperative navigation during laparoscopic rectal cancer surgery with left colic artery preservation

BACKGROUND Prior studies have shown that preserving the left colic artery(LCA)during laparo-scopic radical resection for rectal cancer(RC)can reduce the occurrence of anasto-motic leakage(AL),without compromising oncological outcomes.However,anatomical variations in the branches of the inferior mesenteric artery(IMA)and LCA present significant surgical challenges.In this study,we present our novel three dimensional(3D)printed IMA model designed to facilitate preoperative rehearsal and intraoperative navigation to analyze its impact on surgical safety.AIM To investigate the effect of 3D IMA models on preserving the LCA during RC surgery.METHODS We retrospectively collected clinical dates from patients with RC who underwent laparoscopic radical resection from January 2022 to May 2024 at Fuyang People’s Hospital.Patients were divided into the 3D printing and control groups for sta-tistical analysis of perioperative characteristics.RESULTS The 3D printing observation group comprised of 72 patients,while the control group comprised 68 patients.The operation time(174.5±38.2 minutes vs 198.5±49.6 minutes,P=0.002),intraoperative blood loss(43.9±31.3 mL vs 58.2±30.8 mL,P=0.005),duration of hospitalization(13.1±3.1 days vs 15.9±5.6 days,P<0.001),postoperative recovery time(8.6±2.6 days vs 10.5±4.9 days,P=0.007),and the postoperative complication rate(P<0.05)were all significantly lower in the observation group.CONCLUSION Utilization of a 3D-printed IMA model in laparoscopic radical resection of RC can assist surgeons in understanding the LCA anatomy preoperatively,thereby reducing intraoperative bleeding and shortening operating time,demonstrating better clinical application potential.

Successful treatment of nightmares may reduce psychotic symptoms in schizophrenia

Nightmares occur more frequently in patients with schizophrenia than they do in the general population. Nightmares are profoundly distressing and may exacerbate daytime psychotic symptoms and undermine day-to-day function. Clinicians do not often ask aboutnightmares in the context of psychotic illness and patients may underreport them or, if nightmares are reported, they may be disregarded; it may be assumed that they will disappear with antipsychotic medication and that they do not, therefore, require separate intervention. This is a missed opportunity because Image Rehearsal Therapy, among other psychological and pharmacological interventions, has proven effective for nightmares in nonschizophrenia populations and should be considered at an early stage of psychotic illness as an important adjunct to standard treatment. There is active ongoing research in this field, which will undoubtedly benefit patients with schizophrenia in the future.

John Dewey on the Reflective Moral Life： Renewing His Lessons for Moral Education Today

Moral education as practiced in schools today roughly falls into two kinds, either taught as an independent subject or practiced as a form of school-wide social learning. Dewey＇s criticism of rigid moral training in traditional schools gives credence to the latter trend. For instance, in 2000 Taiwan＇s Ministry of Education decided to eliminate moral education as a required subject from the national school curriculum and suggested that all schools and teachers should infuse morality into the school culture as a whole. More than a decade has passed, and many people question whether schools have been infused with morality. Some even suggest that not teaching morality in schools has led to an eroding of moral standards in society at large. In light of this controversy, in this paper, I take a close look at Dewey＇s conception of the nature of morality, and in particular, his distinction between reflective and customary morality. Drawing on Dewey＇s own moral struggles in life to illustrate his major contentions, I explore what Dewey means by moral reflection, dramatic rehearsal, and growth. Finally, I argue for the importance of committed moral values as the foundation for realizing Dewey＇s ideal of reflective intelligence. Overall, I aim to unpack the underlying assumptions in Dewey＇s ideas in order to renew his lessons for moral education today.

Effects of the Pre-Task Planning Mode on the Listening Comprehension of Chinese EFL Learners

This study aims at investigating the effects of the pre-task planning mode on listening comprehension of Chinese EFL （English as a foreign language） learners as well as students＇ opinions towards the pre-task planning mode Three step~., namely, concept mapping, strategic planning, as well as rehearsal, are employed in the pre-task planning mode in the present study. There are altogether 40 second-year English majors participated in the present study, and they are randomly assigned into the experimental group and the control group. The instruments employed in the present study to achieve the research purposes include the listening comprehension test, the teacher＇s log, the students＇ opinion questionnaires, the students＇ open-ended questionnaires, and the semi-structured interviews. Research findings revealed that there were significant main effects on the listening comprehen,;ion of Chinese EFL learners after the training by the pre-task planning mode. Moreover, the students held positive attitudes towards the pre-task planning mode
