OBJECTIVE: The use of adipose-derived stem cells (ADSCs) to cure the optic nerve injury was never shown previously. Here, we implanted purified ADSCs into optic nerve injury of rats. MATERIALS AND METHODS: Male Sprague Dawley (SD) rats were used in this study. The vision degeneration was detected by Flash-visual evoked potential (F-VEP) assay. The expression of Macrophage-1 (Mac-1), myeloid differentiation factor 88 (MyD88), and nuclear transcription factor-κB (NF-κB) were studied by Western blot...

The effect of rutin on ovarian ischemia-reperfusion (I/R) injury was investigated in this experimental study. Eighteen Wistar albino female rats were divided into three groups as follows: I/R group (IRG; n = 6), 50 mg/kg rutin + I/R group (RG; n = 6), and a healthy control group scheduled for a sham operation (SG; n = 6). 2 h of ischemia and following 2 h of reperfusion were created in the IRG and RG by using a torsion model involving atraumatic vascular clips. Rutin, a flavonoid glycoside, was injected intraperitoneally at the dose of 50 mg/kg to RG group 1 h before reperfusion...

The effects of propofol vs. sevoflurane combined with remifentanil on the pain index, inflammatory factors and postoperative cognitive function in spine fracture patients were studied and analyzed. A total of 62 patients with vertebral fracture were randomly divided into the propofol group (P group, n=41) and the sevoflurane group (S group, n=41). P group used induction anesthesia with propofol, and maintained anesthesia via intravenous injection of remifentanil. While patients in S group received induction anesthesia with sevoflurane, and also remifentanil as the maintained anesthesia...

Helicobacter pylori (H. pylori) is the major stomach carcinogen, but the molecular mechanism responsible for the pathogenesis of cancer development mediated by H. pylori infection is still unclear. Aquaporin 3 (AQP3), overexpressed in gastric carcinoma, has a crucial role in gastric carcinogenesis and progression. However, the triggers and precise regulations for AQP3 upregulation during gastric carcinogens also remain unknown. Here we report that H. pylori infection-mediated carcinogenesis may be mechanistically depended on the upregulation of AQP3 expression via reactive oxygen species (ROS) pathway activation in the stomach...

Neutrophil infiltration of the chorioamnion-decidua tissue at the maternal-fetal interface (chorioamnionitis) is a leading cause of prematurity, fetal inflammation, and perinatal mortality. We induced chorioamnionitis in preterm rhesus macaques by intraamniotic injection of LPS. Here, we show that, during chorioamnionitis, the amnion upregulated phospho-IRAK1-expressed neutrophil chemoattractants CXCL8 and CSF3 in an IL-1-dependent manner. IL-1R blockade decreased chorio-decidua neutrophil accumulation, neutrophil activation, and IL-6 and prostaglandin E2 concentrations in the amniotic fluid...

Mouse models of lupus have shown that multiple immune cell types contribute to autoimmune disease. This study sought to investigate the involvement of B cells and dendritic cells in supporting the expansion of inflammatory and regulatory CD4+ T cells that are critical for lupus pathogenesis. We used lupus-prone B6.NZM2410.Sle1.Sle2.Sle3 (TC) and congenic C57BL/6J (B6) control mice to investigate how the genetic predisposition of these two cell types controls the activity of normal B6 T cells. Using an allogeneic in vitro assay, we showed that TC B1-a and conventional B cells expanded Th17 cells significantly more than their B6 counterparts...

The purpose of this study was to evaluate the protective effects of α-mangostin against acetaminophen (APAP)-induced acute liver injury and discover its potential mechanisms in mice. Mice were continuously treated with α-mangostin (12.5 and 25mg/kg) by intragastric administration once daily for 6 days, and injected intraperitoneally with APAP (300mg/kg) after 1h of α-mangostin administration on the last day. After APAP exposure for 24h, the liver and serum were gathered to evaluate the hepatotoxicity. The results showed that α-mangostin effectively decreased the serum levels of alanine aminotransferase, aspartate transaminase, tumor necrosis factor (TNF-α), interleukin-1β and 6 (IL-1β, IL-6), and hepatic malondialdehyde level; and recovered hepatic glutathione (GSH), superoxide dismutase and catalase activities...

Low-grade pro-inflammatory state and leptin resistance are important underlying mechanisms that contribute to obesityassociated hypertension. We tested the hypothesis that Astragaloside IV (As IV), known to counteract obesity and hypertension, could prevent obesity-associated hypertension by inhibiting pro-inflammatory reaction and leptin resistance. High-fat diet (HFD) induced obese rats were randomly assigned to three groups: the HFD control group (HF con group), As IV group, and the As IV + α-bungaratoxin (α-BGT) group (As IV+α-BGT group)...

Heterophyllin B (HB), an active cyclic peptide, is a compound existing in the ethyl acetate extract of Pseudostellaria heterophylla (Miq.) Pax and exhibited the activity of inhibiting the production of NO and cytokines, such as IL-1β and IL-6, in LPS-stimulated RAW 264.7 macrophages. In addition, HB suppressed the production of ROS and the apoptosis induced by LPS in RAW 264.7 macrophages. The underlying mechanism was investigated in the LPS-induced RAW 264.7 cells. The results showed that HB decreased the level of IL-1β and IL-6 expression by qRT-PCR analysis...

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide, and precision therapeutic will be a benefit for the NAFLD regression. In this study, we observed low microRNA 146 b (miR-146 b) expression in NAFLD mice model induced by methionine-choline-deficient diet (MCD) compared with control group. Furthermore, miR-146b-/- mice induced MCD exhibited severe liver steatosis and hepatitis. A bio-distribution study showed that novel Lactosylated PDMAEMA nanoparticles effectively targeted hepatocytes Lac-PDMAEMA...

OBJECTIVE: To observe the effect of acupuncture on the expression of silent information regulator factor 2-related enzyme 1 (SIRT 1) and nuclear factor-κB (NF-κB) in rats with acute cerebral ischemia (ACI), so as to explore its mechanisms underlying improvement of ACI. METHODS: One hundred female SD rats were randomly divided into 5 groups: normal control (normal), sham-operation (sham), model, non-acupoint and acupoint, with 20 rats in each. The ACI model was established by occlusion (electric coagulation) of the middle cerebral artery after craniotomy...

Background: Cerebral hypoperfusion is a pivotal risk factor for vascular dementia (VD), for which effective therapy remains inadequate. Persistent inflammatory responses and excessive chemotaxis of microglia/macrophages in the brain may accelerate the progression of VD. Endocannabinoids are involved in neuronal protection against inflammation-induced neuronal injury. Cannabinoids acting at cannabinoid receptor 2 (CB2 R) can decrease inflammation. Based on the identification of paeoniflorin (PF) as a CB2 R agonist, we investigated the neuroprotective and microglia/macrophages M1 to M2 polarization promoting effects of PF in a permanent four-vessel occlusion rat model...

ETHNOPHARMACOLOGICAL RELEVANCE: Kansui, the root of Euphorbia kansui S.L.Liou ex S.B.Ho (E.kansui), is a classical traditional Chinese medicine (TCM) with certain toxicity. According to the theory of TCM, kansui fry-baked with vinegar (VEK) possesses low toxicity and mild diuretic and purgative efficacy. In clinical practice, it is commonly used for the treatment of ascites and oliguria. The present study aimed to evaluate the toxicity and efficacy of different fractions of VEK and reveal the underlying material basis by employing an animal model of malignant ascites effusion (MAE) in rats...

INTRODUCTION: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb) that mainly affects the lungs. Along the course of pulmonary TB there are remarkable changes in the production of cytokines that cause endocrine changes. So far, it is not known the physiological and histological changes in the male reproductive system during pulmonary TB. OBJECTIVE: To investigate whether pulmonary TB produces histological alterations of the BALB/c mice reproductive organs, as well as abnormalities in spermatogenesis, serum testosterone concentrations and expression of testicular cytokines...
