The potential therapeutic roles of dental pulp stem cells in spinal cord injury.

Spinal cord injury (SCI) can lead to serious functional disorders, which have serious impacts on patients and society. The current traditional treatments of SCI are not effective the injured spinal cord is difficult to repair and regenerate. In recent years, stem cell transplantation for the treatment of SCI has been a hot research topic.

Parental Postoperative Pain Management Perceptions, Attitudes, and Practices in Pediatric Limb Fractures.

Background: Post-surgical pain in children is common, severe, and inadequately controlled. An effective model should involve the participation of parents.

Aims: To investigate parental perceptions, attitudes, and practices in postoperative pain management in children with limb fractures and analyze the factors affecting parental practices.

The deubiquitinating enzyme 13 retards non-alcoholic steatohepatitis blocking inactive rhomboid protein 2-dependent pathway.

Nowadays potential preclinical drugs for the treatment of nonalcoholic steatohepatitis (NASH) have failed to achieve expected therapeutic efficacy because the pathogenic mechanisms are underestimated. Inactive rhomboid protein 2 (IRHOM2), a promising target for treatment of inflammation-related diseases, contributes to deregulated hepatocyte metabolism-associated nonalcoholic steatohepatitis (NASH) progression. However, the molecular mechanism underlying Irhom2 regulation is still not completely understood.

A New Dressing System for Wound in Enhanced-Recovery Total Hip Arthroplasty: A Randomized and Controlled Trial.

Background: Currently, there is a paucity of recommendations in regards to dressing selection within the enhanced recovery after surgery protocol. We devised a new dressing system to accelerate the recovery after total hip arthroplasty (THA). We aimed to present our experience with this new dressing system as an adjunct to wound management in THA and to evaluate its performance.

Treatment of postoperative non-union with internal fixation loosening of Garden IV femoral neck fracture with teriparatide in a young adult: A case report.

Background: Postoperative non-union of femoral neck fracture often needs secondary operation. We report a case of a postoperative non-union of femoral neck fracture treated with teriparatide.

Case Presentation: A young male patient with Garden IV femoral neck fracture who showed no obvious signs of healing 3 months after percutaneous hollow nail fixation in which the fracture line was enlarged and the hollow nail was withdrawn.

Hepatocyte phosphatase DUSP22 mitigates NASH-HCC progression by targeting FAK.

Nonalcoholic steatohepatitis (NASH), a common clinical disease, is becoming a leading cause of hepatocellular carcinoma (HCC). Dual specificity phosphatase 22 (DUSP22, also known as JKAP or JSP-1) expressed in numerous tissues plays essential biological functions in immune responses and tumor growth. However, the effects of DUSP22 on NASH still remain unknown.

The E3 ubiquitin-protein ligase Trim31 alleviates non-alcoholic fatty liver disease by targeting Rhbdf2 in mouse hepatocytes.

Systemic metabolic syndrome significantly increases the risk of morbidity and mortality in patients with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). However, no effective therapeutic strategies are available, practically because our understanding of its complicated pathogenesis is poor. Here we identify the tripartite motif-containing protein 31 (Trim31) as an endogenous inhibitor of rhomboid 5 homolog 2 (Rhbdf2), and we further determine that Trim31 directly binds to Rhbdf2 and facilitates its proteasomal degradation.

Nrf2 mitigates prolonged PM2.5 exposure-triggered liver inflammation by positively regulating SIKE activity: Protection by Juglanin.

Air pollution containing particulate matter (PM) less than 2.5 μm (PM) plays an essential role in regulating hepatic disease. However, its molecular mechanism is not yet clear, lacking effective therapeutic strategies.

Oral flavonoid fisetin treatment protects against prolonged high-fat-diet-induced cardiac dysfunction by regulation of multicombined signaling.

Excess high-fat diet (HFD) intake predisposes the occurrence of obesity-associated heart injury, but the mechanism is elusive. Fisetin (FIS), as a natural flavonoid, has potential activities to alleviate obesity-induced metabolic syndrome. However, the underlying molecular mechanisms of FIS against HFD-induced cardiac injury remain unclear.

NLRC4 Mutation in flagellin-derived peptide CBLB502 ligand-binding domain reduces the inflammatory response but not radioprotective activity.

Bacterial flagellin is a pathogen-associated molecular pattern recognized by surface-localized Toll-like receptor 5 (TLR5) and cytosolic NOD-like receptor protein 4 (NLRC4). CBLB502, derived from Salmonella flagellin, exhibits high radioprotective efficacy in mice and primates by regulating TLR5 and the nuclear factor kappa B (NF-κB) signaling pathway. In this study, we examined the effects of CBLB502 and mutations in its NLRC4- and TLR5-binding domains on radioprotective efficacy and the immune inflammatory response.

Glycerol kinase interacts with nuclear receptor NR4A1 and regulates glucose metabolism in the liver.

Glycerol kinase (Gyk), consisting of 4 isoforms, plays a critical role in metabolism by converting glycerol to glycerol 3-phosphate in an ATP-dependent reaction. Only Gyk isoform b is present in whole cells, but its function in the nucleus remains elusive. Previous studies have shown that nuclear orphan receptor subfamily 4 group A member (NR4A)-1 is an important regulator of hepatic glucose homeostasis and lipid metabolism in adipose tissue.

ABRO1 promotes NLRP3 inflammasome activation through regulation of NLRP3 deubiquitination.

Deubiquitination of NLRP3 has been suggested to contribute to inflammasome activation, but the roles and molecular mechanisms are still unclear. We here demonstrate that ABRO1, a subunit of the BRISC deubiquitinase complex, is necessary for optimal NLRP3-ASC complex formation, ASC oligomerization, caspase-1 activation, and IL-1β and IL-18 production upon treatment with NLRP3 ligands after the priming step, indicating that efficient NLRP3 activation requires ABRO1. Moreover, we report that ABRO1 deficiency results in a remarkable attenuation in the syndrome severity of NLRP3-associated inflammatory diseases, including MSU- and Alum-induced peritonitis and LPS-induced sepsis in mice.

Existence of Th22 in children and evaluation of IL-22 + CD4 + T, Th17, and other T cell effector subsets from healthy children compared to adults.

Background: Children are prone to get infections, especially in the respiratory system and the gut mainly because their immune system is immature. T cells significantly contribute to the prevention of infections, and different helper T cell (Th) subsets play different anti-pathogen roles. Interleukin (IL)-22 producing by T-helper 22 cells (Th22) play an important role in host defense against Gram-negative bacterial organisms in gut and lung.

Hot environments decrease exercise capacity and elevate multiple neurotransmitters.

Aims: This study aimed to test the hypothesis that different neurotransmitters and hormones are presented at exercise fatigue in hot temperatures with differing relative humidities (RH).

Main Methods: Eight trained male athletes performed a graded maximum oxygen consumption (VO2max) test in five different environmental conditions, namely, 21°C/20% RH (Normal), 33°C/20% RH (Hot 20%), 33°C/40% RH (Hot 40%), 33°C/60% RH (Hot 60%), and 33°C/80% RH (Hot 80%). Blood samples were taken pre- and post-exercise and analyzed for noradrenaline (NA), adrenaline (ADR), dopamine (DA), serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), and prolactin (PRL).

[The effect and mechanism of Yiqi Tongluo Jiedu capsule against cerebral ischemia reperfusion injury].

To observe the effect and mechanism of Yiqi Tongluo Jiedu capsule aganist cerebral ischemia reperfusion injury, the SD rats were randomly divided into following groups: sham-operated group, model group, the group of low, medium and high dose of Yiqi Tongluo Jiedu capsule, and nimodipine group. Using focal middle cerebral artery embolization (MCAO) model, following items were observed: symptoms of neurological deficit score; infarct volume; activity of SOD, content of MDA and NO, activity of NOS of ischemic brain tissue; Bcl-2 and Bax protein expression; content of IL-1beta, IL-6 and TNFalpha in serum; IL-1beta mRNA expression of ischemic brain tissue. Results showed that Yiqi Tongluo Jiedu capsule could significantly reduce the symptoms of neurological deficits, promote the recovery symptoms of neurological deficits; narrow infarct volume of brain tissue obviously, reduce the percentage of infarct volume; raise activity of SOD, reduce content of MDA and NO, reduce activity of NOS; increase Bcl-2 protein, reduce Bax expression; reduce content of IL-1beta, IL-6 and TNFa in serum; reduce IL-1beta mRNA expression of ischemic brain tissue.
