The effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education: a pilot randomized controlled trial.

Background: Effective teaching methods are needed to improve students' abilities in hand-eye coordination and understanding of cardiac anatomy in echocardiography education. Simulation devices have emerged as innovative teaching tools and exhibited distinctive advantages due to their ability to provide vivid and visual learning experiences. This study aimed to investigate the effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education.

A meta-analysis of the efficacy of programmed cell death 1/its ligand inhibitors plus cytotoxic T-lymphocyte-associated antigen 4 inhibitors in non-small cell lung cancer.

Immune checkpoint inhibitors (ICIs), either as monotherapy or in combination with chemotherapy, have improved the therapeutic outcome for non-small cell lung cancer (NSCLC). However, the efficacy of combination therapies, such as programmed cell death 1(PD-1)/its ligand (PD-L1) and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitors, in targeting different pathways remains unclear. We performed a meta-analysis to determine whether the addition of a CTLA-4 inhibitor to PD-1/PD-L1 therapy improves the efficacy of PD-1/PD-L1 monotherapy in NSCLC.

Effectiveness of preoperative ultrasonography in predicting metachronous contralateral inguinal hernia in children: a single-arm prospective study using a historical control for comparison.

Purpose: To analyze the value of ultrasonography in predicting metachronous contralateral inguinal hernia (MCIH) and diagnosing contralateral persistent processus vaginalis (CPPV) in children with unilateral inguinal hernia, a prospective study was conducted.

Methods: All participants underwent a preoperative ultrasound on the contralateral groin. Patients in group A1 received operating procedure according to ultrasound results (patients with negative contralateral US results received hernia repair on the affected side), and patients in group A2 received operation according to laparoscopic results (patients received hernia repair and CPPV ligation).

Comparative and phylogenetic analysis of complete chloroplast genomes from seven taxa (Lauraceae).

The genus is considered to be one of the most enigmatic groups in Lauraceae, mainly distributed in tropical and subtropical regions of Southeast Asia. The genus contains valuable oilseed and medicinal tree species. However, there are few studies on the genus at present, and its interspecific relationship is still unclear.

Fractional amplitude of low frequency fluctuation in drug-naïve first-episode patients with anorexia nervosa: A resting-state fMRI study.

To characterize the fractional amplitude of low-frequency fluctuation (fALFF) in drug-naïve first-episode female patients with anorexia nervosa (AN) using resting-state functional magnetic resonance imaging (rs-fMRI).Whole brain rs-fMRI data were collected from 7 drug-naïve first-episode female patients with DSM-5 AN and 14 age-matched healthy female controls. fALFF values were calculated and compared between the two groups using a two-sample t test.

Regional homogeneity and functional connectivity analysis of resting-state magnetic resonance in patients with bipolar II disorder.

To explore the characteristics of local brain activity in patients with bipolar depression and its correlation with clinical features.In accord with the diagnostic and statistical manual of mental disorders-IV of bipolar disorder, 21 patients were enrolled while 21 healthy controls were matched with similar gender, age, level of educations. A 3.

Altered microstructure of brain white matter in females with anorexia nervosa: a diffusion tensor imaging study.

Objective: Structural studies have reported anorexia nervosa (AN) patients with abnormal gray matter in several brain regions and dysfunction in some connected neural circuits. However, the role of white matter (WM) in AN patients has rarely been investigated. The present study aimed to assess alterations in WM microstructure of the entire brain in females with AN using a voxel-based method on diffusion tensor imaging (DTI) data.

Effects of 5-hydroxytryptamine 2C receptor agonist MK212 and 2A receptor antagonist MDL100907 on maternal behavior in postpartum female rats.

Maternal behavior in rats is a highly motivated and well-organized social behavior. Given the known roles of serotonin (5-HT) in emotion, motivation, social behavior, and major depression - and its known interaction with dopamine - it is likely that serotonin also plays a crucial role in this behavior. So far, there are surprisingly few studies focusing on 5-HT in maternal behavior, except for maternal aggression.

[Relationship between the grading of periventricular echodensities and periventricular white matter cystic lesions in preterm infants].

Objective: To understand the relationship of the grading of periventricular echodensities (PVE) with the morbidity and the occurrence time of periventricular white matter cystic lesions in preterm infants.

Methods: A retrospective, single-centre cohort study of 120 preterm infants with PVE diagnosed by ultrasonography between February 2005 and May 2008 was performed. The infants had a median gestational age of 32 weeks and a median birth weight of 2 230 g.

[Ultrasonographic findings of intussusception complicated by intestinal necrosis in children].

Objective: The information on the ultrasonographic features of pediatric intussusception complicated by intestinal necrosis is limited at present. This study aimed to investigate the ultrasonographic findings of this disorder in children in order to provide references for selecting a right means of reduction in clinical practice.

Methods: The ultrasonographic findings of 48 children with intussusception complicated by intestinal necrosis and who underwent operative reduction between 2004 and 2006 were reviewed retrospectively.
