PV and SST neurons in the anterior cingulate cortex regulate social disorders in adulthood induced by sensory abnormalities in childhood.

Objective: Childhood sensory abnormalities experience has a crucial influence on the structure and function of the adult brain. The underlying mechanism of neurological function induced by childhood sensory abnormalities experience is still unclear. Our study was to investigate whether the GABAergic neurons in the anterior cingulate cortex (ACC) regulate social disorders caused by childhood sensory abnormalities experience.

Characteristics of traumatic brain injury models: from macroscopic blood flow changes to microscopic mitochondrial changes.

Controlled cortical impingement is a widely accepted method to induce traumatic brain injury to establish a traumatic brain injury animal model. A strike depth of 1 mm at a certain speed is recommended for a moderate brain injury and a depth of > 2 mm is used to induce severe brain injury. However, the different effects and underlying mechanisms of these two model types have not been proven.

Extracellular matrix protein laminin β1 regulates pain sensitivity and anxiodepression-like behaviors in mice.

Patients with neuropathic pain often experience comorbid psychiatric disorders. Cellular plasticity in the anterior cingulate cortex (ACC) is assumed to be a critical interface for pain perception and emotion. However, substantial efforts have thus far been focused on the intracellular mechanisms of plasticity rather than the extracellular alterations that might trigger and facilitate intracellular changes.

The analgesic effect of rolipram is associated with the inhibition of the activation of the spinal astrocytic JNK/CCL2 pathway in bone cancer pain.

Bone cancer pain (BCP) is one of the most difficult and intractable tasks for pain management, which is associated with spinal 'neuron-astrocytic' activation. The activation of the c-Jun N-terminal kinase (JNK)/chemokine (C-C motif) ligand (CCL2) signaling pathway has been reported to be critical for neuropathic pain. Rolipram (ROL), a selective phosphodiesterase 4 inhibitor, possesses potent anti-inflammatory and anti-nociceptive activities.

Midazolam and ropivacaine act synergistically to inhibit bone cancer pain with different mechanisms in rats.

Analgesic strategy of a single drug analgesia in bone cancer pain (BCP) has shifted to combined analgesia with different drugs which have different mechanism. After tumor cell inculation, the activation of signal transducer and activator of transcription (STAT3) and extracellular signal-regulated kinase (ERK) signaling pathway are involved in the development and maintenance of BCP, whereas a decrease in the expression of spinal STAT3 and ERK through using their specific blocker, lead to attenuation of BCP. Hence, in this study, we clarified that intrathecal (i.

Anxiolytic effect of essential oils of Salvia miltiorrhiza in rats.

This study aims to investigate the anxiolytic effects of essential oil from S. miltiorrhiza in rats. The elevated plus maze test and the social interaction test were performed to evaluate the anxiolytic effects of essential oil.

As2O3 induces apoptosis in human hepatocellular carcinoma HepG2 cells through a ROS-mediated mitochondrial pathway and activation of caspases.

Arsenic trioxide (As2O3) has been shown to induce apoptosis in hepatocellular carcinoma cells. However, the molecular mechanism of As2O3-induced apoptosis in the hepatocellular carcinoma cells remains poorly understood. Here, we investigated the impact of As2O3 exposure on the human hepatocellular carcinoma cell line HepG2 and examined the underlying mechanism of cell death.

Prognostic value of p53 alterations in human osteosarcoma: a meta analysis.

Tumor suppressor gene p53 functions as the guardian of the human genome and mutations in p53 contribute to cancer development. However, studies that investigated the potential of p53 as a prognostic marker in osteosarcoma patients have yielded inconclusive results. Based on recommendation of the Cochrane Collaboration, this meta-analysis was conducted using data from the 17 published studies to evaluate the association of p53 alterations with clinical outcome of osteosarcoma patients.

Patchouli alcohol dampens lipopolysaccharide induced mastitis in mice.

Patchouli alcohol (PA), a tricyclic sesquiterpene isolated from Pogostemonis Herba, has been known to exhibit antioxidant, anti-inflammatory, and other important therapeutic activities. The aim of this study was to investigate the effects of PA on LPS-induced mastitis in vivo and the possible mechanism. The mouse model of mastitis was induced by injection of LPS through the duct of mammary gland.

Birthdate study of GABAergic neurons in the lumbar spinal cord of the glutamic acid decarboxylase 67-green fluorescent protein knock-in mouse.

Despite the abundance of studies on γ-aminobutyric acid (GABA) ergic neuron distribution in the mouse developing spinal cord, no investigation has been devoted so far to their birthdates. In order to determine the spinal neurogenesis of a specific phenotype, the GABAergic neurons in the spinal cord, we injected bromodeoxyuridine (BrdU) at different developmental stages of the glutamic acid decarboxylase (GAD)67-green fluorescent protein (GFP) knock-in mice. We thus used GFP to mark GABAergic neurons and labeled newly born cells with the S-phase marker BrdU at different embryonic stages.

Antioxidant therapy for pain relief in patients with chronic pancreatitis: systematic review and meta-analysis.

Background: Currently, there is no specific therapy for chronic pancreatitis (CP). The treatment of micronutrient antioxidant therapy for painful CP has been sporadically used for more than 30 years, however, its efficacy are still poorly understood.

Objective: The purpose of this meta-analysis is to investigate the safety and efficacy of antioxidant therapy for pain relief in patients with CP.
