Intrathecally administered pizotifen alleviates neuropathic and inflammatory pain in mice by enhancing GABAergic inhibition.

Chronic pain, such as chronic neuropathic pain and chronic inflammatory pain, is often difficult to manage and bring great trouble to patients. 5-HT plays a key role in the process of pain transmission both in centrally and peripherally. Tricyclic antidepressants (TCA) such as amitriptyline are classical 5-HT reuptake inhibitors, are recommended as the first-line treatment for chronic pain.

Chinese Association for the Study of Pain: Expert consensus on chronic postsurgical pain.

Chronic postsurgical pain is a common surgical complication that severely reduces a patient's quality of life. Many perioperative interventions and management strategies have been developed for reducing and managing chronic postsurgical pain. Under the leadership of the Chinese Association for the Study of Pain, an editorial committee was formed for chronic postsurgical pain diagnosis and treatment by experts in relevant fields.

Finite element analysis of wedge and biconcave deformity in four different height restoration after augmentation of osteoporotic vertebral compression fractures.

Purpose: Biomechanical comparison of wedge and biconcave deformity of different height restoration after augmentation of osteoporotic vertebral compression fractures was analyzed by three-dimensional finite element analysis (FEA).

Methods: Three-dimensional finite element model (FEM) of T11-L2 segment was constructed from CT scan of elderly osteoporosis patient. The von Mises stresses of vertebrae, intervertebral disc, facet joints, displacement, and range of motion (ROM) of wedge and biconcave deformity were compared at four different heights (Genant 0-3 grade) after T12 vertebral augmentation.

Thermographic follow-up of postherpetic neuralgia (PHN) subsequent to Ramsay Hunt syndrome with multicranial nerve (V, VII, VIII and IX) involvement: a case report.

Background: Ramsay Hunt syndrome (RHS) is caused by a reactivation of varicella-zoster virus (VZV) infection, and it is characterized by the symptoms of facial paralysis, otalgia, auricular rash, and/or an oral lesion. Elderly patients or immunocompromised patients, deep pain at the initial visit and no prompt treatment are significant predictors of postherpetic neuralgia (PHN). When PHN occurs, especially involved cranial polyneuropathy, multiple modalities should be administered for patients with the intractable PHN.

Remimazolam tosilate in upper gastrointestinal endoscopy: A multicenter, randomized, non-inferiority, phase III trial.

Background And Aim: Remimazolam tosilate (RT) is a new short-acting GABA(A) receptor agonist, having potential to be an effective option for procedural sedation. Here, we aimed to compare the efficacy and safety of RT with propofol in patients undergoing upper gastrointestinal endoscopy.

Methods: This positive-controlled, non-inferiority, phase III trial recruited patients at 17 centers, between September 2017 and November 2017.

Intrathecal delivery of hydromorphone vs morphine for refractory cancer pain: a multicenter, randomized, single-blind, controlled noninferiority trial.

Hydromorphone is an alternative to morphine for intrathecal drug delivery system to treat refractory cancer pain; however, there is not enough clinical evidence to prove it. In our study, 233 patients from 12 different pain management centers across China were enrolled, 121 and 112 in the intrathecal hydromorphone (ITHM) and intrathecal morphine (ITMO) groups, respectively. The primary outcome was the clinical success rate, which was defined as ratio of patients achieving ≥50% pain relief.

α-lipoic acid attenuates spatial learning and memory impairment induced by hepatectomy.

The aim of the present study was to compare the effects of α-lipoic acid (ALA) on postoperative cognitive dysfunction (POCD) between wild type (WT) and leptin receptor-deficient (db/db) mice and to elucidate the underlying mechanism of treatment with ALA. The present study compared the effects of ALA on spatial learning and memory of WT and db/db mice using a Morris water maze following hepatectomy. The expression levels of proteins, including cyclin-dependent kinase 5 (Cdk5), tau, phosphorylated tau and amyloid β (Aβ) were measured in the hippocampus.

The Diagnosis and Therapy of Degenerative Knee Joint Disease: Expert Consensus from the Chinese Pain Medicine Panel.

At present, there are many constantly updated guidelines and consensuses on the diagnosis and treatment of osteoarthritis both at home and abroad. The recommendations established using methods of evidence-based medicine has experienced strict research on controlling bias and promoting reproduction rate. As a result, the previous evidence was reevaluated, and a lot of changes were provoked in the diagnosis and treatment concept of osteoarthritis.

Risk factors for early postoperative cognitive dysfunction after colorectal surgery.

Background: It has been reported that postoperative cognitive dysfunction (POCD) is correlated with the degeneration of the central nervous system, oxidative stress, inflammation, and endocrine and immune dysfunction. Increased age, predisposed comorbidity, long surgery time, and prolonged stay in the intensive care unit have been reported to be risk factors for developing POCD for cardiac surgery. In the present study, the risk factors of early POCD after colorectal surgery were investigated.

LncRNA X inactive specific transcript contributes to neuropathic pain development by sponging miR-154-5p via inducing toll-like receptor 5 in CCI rat models.

Noncoding RNAs, including long non-coding RNAs (lncRNAs) and microRNAs, are involved in the development of neuropathic pain. Currently, we investigated that lncRNA X inactive-specific transcript (XIST) and toll-like receptor 5 (TLR5) were greatly upregulated in chronic constriction injury rat models, whereas miR-154-5p (microRNA-154-5p) was significantly downregulated. Bioinformatics analysis was used to predict miR-154-5p as a target gene of XIST, and dual-luciferase reporter tests proved the correlation between them.

Network meta-analysis of percutaneous vertebroplasty, percutaneous kyphoplasty, nerve block, and conservative treatment for nonsurgery options of acute/subacute and chronic osteoporotic vertebral compression fractures (OVCFs) in short-term and long-term effects.

Background: Osteoporotic vertebral compression fractures (OVCFs) commonly afflicts most aged people resulting back pain, substantial vertebral deformity, functional disability, decreased quality of life, and increased adjacent spinal fractures and mortality. Percutaneous vertebral augmentation (PVA) included percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP), nerve block (NB), and conservative treatment (CT) are used for the nonsurgery treatment strategy of OVCFs, however, current evaluation of their efficacy remains controversial.

Methods And Analysis: A systematic literature search was carried out in PubMed, EMBASE, Web of Knowledge, and the Cochrane Central Register of Controlled Trials up to October 31, 2017.

Celecoxib inhibits insulin-like growth factor 1 induced growth and invasion in non-small cell lung cancer.

Despite a large number of studies indicating that celecoxib plays an important role in the prevention and treatment of tumors, the detailed molecular mechanisms are not well understood. The aim of the present study was to investigate the effect of celecoxib on insulin-like growth factor 1 (IGF-1)-induced growth and invasion in non-small cell lung cancer (NSCLC). For these experiments, IGF-1-induced cell growth and invasion were analyzed in A549 cells in the presence and absence of celecoxib.

Background: The purpose of this study was to elucidate the possible beneficial effects of adiponectin (APN) on acute lung injury in a rat model of sepsis.

Methods: We subjected male Sprague-Dawley rats to cecal ligation and puncture (CLP) to establish sepsis models. We randomly animals divided into four groups: control (C), model (CLP), preemptive APN administration (APN plus CLP), and delayed APN administration (CLP plus APN).

Effects of adiponectin on mortality and its mechanism in a sepsis mouse model.

The mortality of sepsis is increasing and conventional therapies for it have no better therapeutic effects. We investigated the effects of adiponectin (APN) on mortality and high mobility group box 1 (HMGB1) in polymicrobial sepsis mouse models. Sepsis models were established by cecal ligation and puncture (CLP) in BALB/c mice.
