Objectives: To investigate the impact of combined treatment of colorectal cancer (CRC) with electroacupuncture (EA) and capeOX (combined administration of fluorouracil, oxaliplatin and capecitabine) on the tumor volume, weight, spleen coefficient, apoptosis and ferroptosis of tumor tissue, and liver and kidney functions in nude mice with CRC, so as to explore its mechanisms underlying inhibiting CRC and alleviating toxic reactions of capeOX.
Methods: Female Balb/c nude mice were randomly assigned to 3 groups:model, capeOX, and EA+capeOX, with 8 nude mice in each group. The CRC model was established by subcutaneous injection of colon cancer cells at the right inguinal region.
The rapid antidepressant effects of ketamine depend on the N-methyl-D-aspartate (NMDA) receptor containing 2B subunit (NR2B), whose function is influenced by its phosphorylated regulation and distribution within and outside synapses. It remains unclear if ketamine's rapid onset of antidepressant effects relies on the dynamic phosphorylated regulation of NR2B within and outside synapses. Here, we show that ketamine rapidlyalleviated depression-like behaviors and normalized abnormal expression of pTyrNR2B and striatal-enriched protein tyrosine phosphatase (STEP) 61 within and outside synapses in the medial prefrontal cortex (mPFC) induced by chronic unpredictable stress (CUS) and conditional knockdown of STEP 61, a key phosphatase of NR2B, within 1 hour after administration Together, our results delineate the rapid initiation of ketamine's antidepressant effects results from the restoration of NR2B phosphorylation homeostasis within and outside synapses.

Methods: Male and female Sprague-Dawley rats before or during puberty were divided into three groups: control group (CON), low-frequency ES group (LF), and high-frequency ES group (HF). ES included water/food deprivation and reversal of day and night.

Objective: To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children.
Methods: Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.
Background: Although various prediction models of the antidepressant response have been established, the results have not been effectively applied to heterogeneous depression populations, which has seriously limited their clinical value. This study tried to build a more specific and stable model to predict treatment response in depression based on short-term changes in hippocampal metabolites.
Materials And Methods: Seventy-four major depressive disorder (MDD) patients and 20 healthy controls in the test set were prospectively collected and retrospectively analyzed.
Background: Stressful life events (SLEs) are well-established proximal predictors of the onset of depression. However, the fundamental causes of interindividual differences in depression outcomes are poorly understood. This study addressed this depression susceptibility mechanism using a well-powered sample of adults living in China.

Methods: The non-contrast computed tomography (NCCT) images of acute brainstem infarction (ABI) from two medical centers were used as test and validation sets.

Schizophrenia (SCZ) is a common and complex psychiatric disease associated with hereditary and environmental risk factors. MicroRNAs (miRNAs or miRs) are small, noncoding RNA molecules that endogenously regulate gene expression. Single nucleotide polymorphisms (SNPs) in related miRNA genes are associated with susceptibility of the disorder.

Background: Stressful life events (SLEs) are an important causal factor in depression; however, the mechanism by which SLEs cause depression remains unclear. Recent studies suggested that white matter (WM) microstructures might be a potential mediator between SLEs and depression. Hence, we aimed to investigate the concrete correspondence among them using mediation effect models.

The neural circuits involving the hippocampus and nucleus accumbens (NAC) have been studied in rats to uncover the neurochemical and neuroanatomical substrates that regulate PPI. Majority of the studies of the hippocampus on PPI to date have been focused on CA1, CA2, and dentate gyrus (DG) area.

We aimed to investigate the neuroendocrinal pathophysiology and its correlation with clinical symptoms in patients with schizophrenia.
Methods: The present cross-sectional study included 486 inpatients with schizophrenia admitted at a psychiatric hospital in Shanghai within one year, and 154 healthy controls (HC) matched on age and gender.
Objective: To characterize the traits of neuropsychological functioning deficits in patients with attention-deficit/ hyperactivity disorder (ADHD) with comorbid disruptive, impulse-control, and conduct disorders (DICCD).
Methods: Twenty out-patients with ADHD, 20 with ADHD with comorbid DICCD, and 20 with DICCD, all aged 6-16 years, were enrolled in this study, with 20 healthy subjects matched for age, gender and IQ serving as the healthy controls. The patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Revision (DSM-5).
Numerous studies have demonstrated that NMDA stimulation of the rat ventral hippocampus induces hyperactivity and disruption of prepulse inhibition (PPI) and some reports have provided insights into the different neural substrates of these two effects. Bilateral or unilateral NMDA stimulation have been applied in these studies, but have never been compared directly. Thus, results of these studies can be related to each other only with reservations.

Objective: To explore the effectiveness of reducing tension method on the survival and appearance of distally-based pedicle flap.
Methods: Between October 2009 and February 2011, 27 cases of defect of extremity skin and soft tissue were repaired with distally-based pedicle flap through reducing tension flap method. There were 19 males and 8 females with an average age of 31.
Objective: To analyze expression characteristics of human skin epidermal stem cell at different developmental stages, and to explore its biological significance.
Methods: Health skin samples from 28-32 w fetuses (F group), 4-12 y children (C group), and 35-55 y adult (A group) were harvested, with 10 cases in each group. Epidermis were separated using trypsin digestion and EDTA, and human epidermal stem cells were isolated and purified with type IV collagen attachment method.
