Neuropathic pain is induced by primary injury and dysfunction of the nervous system, and is accompanied by the activation of inflammation signaling pathways. Yin Yang 1 (YY1) is reported to be involved in inflammation; however, its role in the development of neuropathic pain is still unclear. In the present study, a neuropathic pain model was established using the bilateral chronic constriction injury (bCCI) method in rats.

Lipoxins (LXs) are important endogenous anti-inflammatory mediators in the body, helping to inhibit neutrophil recruitment and stimulate autophagy in monocytes and macrophages. Here, we investigated the molecular mechanisms underlying the effects of exogenous lipoxin administration on rats with non-compressive disc herniation.

Rats were randomly divided into six groups: Sham control group (Sham), I/R group, sevoflurane group (Se), Toll‑like receptor‑4 (TLR4) inhibitor group (Tak‑242), nuclear factor (NF)‑κB inhibitor group (QNZ) and Sevoflurane post‑conditioning combined with TLR4‑NF‑κB signaling pathway inhibitor group (Se + Tak‑242). Morris water maze test and tetrazolium chloride staining were used to investigate the I/R injury.

Purpose: Research has shown that sevoflurane-induced toxicity causes neurodegeneration in the developing brain. miR-34a has been found to negatively regulate ketamine-induced hippocampal apoptosis and memory impairment. However, the role of miR-34a in sevoflurane-induced hippocampal neurodegeneration remains largely unclear.

Because brain hypoxia is the most common factor of secondary brain injury after traumatic brain injury, we studied the role and possible mechanism of ANDRO in this process using hypoxia-injured astrocytes. Mouse cortical astrocytes C8-D1A (astrocyte type I clone from C57/BL6 strains) were subjected to 3 and 21% of O2 for various times (0-12 h) to establish an astrocyte hypoxia injury model in vitro.

Thirty aged male rats were randomly assigned to 3 groups: Control, model and andrographolide groups. The Morris water maze test was used to examine the spatial memory and learning ability of the rats postoperatively.

A survey was carried out to investigate soil nematode communities in the plant associations of gramineae (Arthraxon lanceolatus, AL; Imperata cylindrica, IC) and leguminosae (Glycine soja, GS) in reclaimed land of copper-mine-tailings and in the plant associations of gramineae (Digitaria chrysoblephara, DC-CK) of peripheral control in Fenghuang Mountain, Tongling City. A total of 1277 nematodes were extracted and sorted into 51 genera. The average individual density of the nematodes was 590 individuals · 100 g(-1) dry soil.

However, previous prospective and retrospective studies reported conflicting results in the effects of epidural anesthesia on post-operative outcomes of colorectal cancer surgery. Therefore, this study aims to pool available evidence to assess the association between epidural anesthesia and the post- operative outcomes in this group of patients.

The objective of this study was to determine if epidural self-controlled analgesia reduced the incidence of chronic pain and improved the quality of life when compared with intravenous self-controlled analgesia. A total of 50 patients diagnosed with advanced cancer who received analgesia treatment were randomly divided into two groups, epidural self-controlled analgesia group (EA group, n = 26) and intravenous self-controlled analgesia group (IA group, n = 24).

The fluorescence quenching observed is attributed to the formation of a complex between HSA and VB, and the reverse temperature effect of the fluorescence quenching has been found and discussed. Fluorescence analysis has proved that there is one classical binding site on HSA for VB with a relative weak binding constant of 1.

The aim of the present study is to assess the role of NF-κB signal pathway and its downstream pro-inflammatory cytokines in the modulation of neuropathic pain, by using small interfering RNAs (siRNAs) technique, which has been shown to result in potent, long-lasting post-transcriptional silencing of specific genes. We developed a highly efficient method of lentivirus-mediated delivery of short-hairpin RNA (shRNA) targeting NF-κBp65 for gene silencing.

We hypothesized that isoflurane induced apoptosis by causing abnormal calcium release from the endoplasmic reticulum (ER) via activation of inositol 1, 4, 5-trisphosphate (IP(3)) receptors. Sevoflurane has a reduced ability to disrupt intracellular calcium homeostasis and is a less potent cytotoxic agent.

Isoflurane, a commonly used inhaled anesthetic, induces apoptosis in rat pheochromocytoma cells (PC12) in a concentration-and time-dependent manner with unknown mechanism. We hypothesized that isoflurane induced apoptosis by causing abnormal calcium release from the endoplasmic reticulum (ER) via activation of inositol 1,4,5-trisphosphate (IP3) receptors. Alzheimer's presenilin-1 (PS1) mutation increased activity of IP3 receptors and therefore rendered cells vulnerable to isoflurane-induced cytotoxicity.
