Introduction: Alleviating postoperative pain from developmental dysplasia of the hip (DDH) surgery is beneficial for paediatric patients. The most commonly used anaesthetic approach currently is general anaesthesia combined with regional nerve blocks. Existing research primarily focuses on studies comparing regional nerve blocks with placebo controls, or studies comparing two different regional nerve blocking techniques. However, the conclusions from these studies offer limited assistance to clinicians in selecting the safest and most effective nerve block. Therefore, we plan to conduct a systematic review and network meta-analysis to compare the efficacy and safety of different regional nerve blocks in managing postoperative pain in children undergoing surgery for DDH.
Methods And Analysis: We will systematically search the following databases: MEDLINE, Embase, Cochrane Central Register of Controlled Trials via Ovid, as well as the Chinese databases CNKI and Wanfang. We will comprehensively search from the inception of each database to April 2024 and will include randomised controlled trials without restrictions on language or publication status. The primary outcome are postoperative pain scores at 4 hours following surgery. The quality of all included trials will be assessed using version 2 of the Cochrane Randomised Trial Risk of Bias Tool. We will employ the GeMTC package in R software for both direct and indirect comparisons within a Bayesian framework using a random effects model. Additionally, the Confidence in Network Meta-Analysis method will be employed to assess the quality of evidence.
Ethics And Dissemination: Ethical approval is not required for this study, as it exclusively involves the compilation of published data. We plan to submit our review to academic conferences and peer-reviewed scholarly journals.

Gamma-aminobutyric acid (GABA) functions as an inhibitory neurotransmitter which blocks the impulses between nerve cells in the brain. Due to the increasing awareness about the health promoting benefits associated with GABA, it is also artificially synthesized and consumed as a nutritional supplement by people in some regions of the world. Though among the fresh vegetables, tomato fruits do contain a comparatively higher amount of GABA (0.

Purpose: To investigate the technique for dorsal median sulcus (DMS) mapping and assess its application value in preserving dorsal columnn (DC) function during intramedullary space occupying surgery based on a single-center experience.
Methods: A retrospective analysis was conducted on 41 cases of intramedullary spinal cord tumor admitted to the Department of Neurosurgery at the First Affiliated Hospital of Xiamen University from March 2017 to August 2023. All included cases underwent intraoperative electrophysiological monitoring, and were divided into a study group (n = 18) and a control group (n = 23), based on whether DMS mapping technique was utilized.

Axons in the mammalian brain show significant diversity in myelination motifs, displaying spatial heterogeneity in sheathing along individual axons and across brain regions. However, its impact on neural signaling and susceptibility to injury remains poorly understood. To address this, we leveraged cable theory and developed model axons replicating the myelin sheath distributions observed experimentally in different regions of the mouse central nervous system.

Retinoic acid (RA) signaling plays multiple essential roles in development of the head and face. Animal models with mutations in genes involved in RA signaling have enabled understanding of craniofacial morphogenic processes that are regulated by the retinoid pathway. During craniofacial morphogenesis RA signaling is active in spatially restricted domains defined by the expression of genes involved in RA production and RA breakdown.

Preclinical and clinical studies have established that autoreactive immunoglobulin G (IgG) can drive neuropathic pain. We recently demonstrated that sciatic nerve chronic constriction injury (CCI) in male and female mice results in the production of pronociceptive IgG, which accumulates around the lumbar region, including within the dorsal root ganglia (DRG) and spinal cord, facilitating the development of neuropathic pain. These data raise the intriguing possibility that neuropathic pain may be alleviated by reducing the accumulation of IgG.
