Interleukin 10 (IL-10) is antinociceptive in various animal models of pain without induction of tolerance, and its mechanism of action was generally believed to be mediated by inhibition of neuroinflammation. Here we reported that intrathecal IL-10 injection dose dependently attenuated mechanical allodynia and thermal hyperalgesiain male and female neuropathic rats, with ED50 values of 40.8 ng and 24 ng, and Emax values of 61.5% MPE and 100% MPE in male rats. Treatment with IL-10 specifically increased expression of the β-endorphin (but not prodynorphin) gene and protein in primary cultures of spinal microglia but not in astrocytes or neurons...

The Warburg effect is a dominant phenotype of most tumor cells. Recent reports have shown that the Warburg effect can be reprogrammed by the tumor microenvironment. Lactic acidosis and glucose deprivation are the common adverse microenvironments in solid tumor. The metabolic reprogramming induced by lactic acid and glucose deprivation remains to be elucidated in glioblastoma. Here, we show that, under glucose deprivation, lactic acid can preserve high ATP levels and resist cell death in U251 cells. At the same time, we find that MCT1 and MCT4 are significantly highly expressed...

Background: The L5 nerve root could be compressed at both L4-5 and L5-S1 regions. If L5 nerve root has confirmed compression at L4-5 level and questionable compression at L5-S1 foramina, performing both surgeries at L4-5 and L5-S1 levels may induce unnecessary extra surgery on L5-S1; however, ignoring foraminal stenosis of L5/S1 may require re-exploration. Methods: Two hundred seventeen patients with L5 nerve root compressed at L4-5 lateral access were performed with L4-5 decompression and interbody fusion...

Long non-coding RNAs (lncRNAs) have been shown to exert essential roles in development and progression of tumors. Here we discovered a novel lncRNA, RAB11B antisense RNA (RAB11B-AS1), which is markedly down-regulated in human osteosarcoma (OS) and associated with OS metastasis and poor prognosis. We find that reduction of RAB11B-AS1 significantly facilitates proliferation, migration and invasiveness and prevents apoptosis of OS cells and results in lower sensitivity to cisplatin in these cells. In contrast, up-regulation of RAB11B-AS1 suppresses the aggressive behaviors of OS cells...

The aim of the present study was to determine whether acetazolamide (Ace) treatment enhances the chemosensitivity of Hep-2 laryngeal cells to cisplatin (Cis). At the logarithmic growth phase, Hep-2 cells were treated with Ace, Cis or both, and cell viability was detected using an MTT assay. The degree of apoptosis was detected using flow cytometry. Expression levels of apoptosis-related proteins, including BCL2 apoptosis regulator (bcl-2), BCL2 associated X (bax) and caspase-3, and of proliferation-related proteins, including proliferating cell nuclear antigen (PCNA) and tumor protein p53 (P53), were detected using western blotting...

MicroRNAs (miRNAs) are important regulators of tumor formation, progression and metastasis. The present study characterized a novel miRNA (miR)-888, as a potent oncomiR in human colorectal cancer (CRC). The clinicopathological investigation on 126 cases of CRC patients demonstrated that the expression level of miR-888 was significantly upregulated in tumors compared with adjacent healthy tissue, and was associated with tumor stage and histological differentiation. A Kaplan-Meier analysis and log-rank test demonstrated that CRC patients with increased miR-888 expression exhibited a decreased overall survival (OS) and disease-free survival (DFS) compared with patients with low miR-888 expression...

BACKGROUND: Venous thromboembolism (VTE) is considered a potentially serious complication of knee arthroscopy and leads to conditions such as deep venous thrombosis (DVT) and pulmonary embolism (PE). Low-molecular-weight heparin (LMWH) is widely employed in knee arthroscopy to reduce perioperative thromboembolic complications. However, the efficacy and safety of LMWH in knee arthroscopy remains unclear. METHODS: Seven randomized controlled clinical trials on LMWH in knee arthroscopy were identified and included in this meta-analysis...

The anatomy of the modiolus and surrounding muscles is complicated and contributes to the morphology of the mouth corner. We used iodine staining and micro-computed tomography (CT) to observe the anatomy of the modiolus and surrounding muscles. Based on the micro-CT images and the 3D model construction, we found that the muscle fibers in the modiolus were oriented continuously in the running direction of the muscle itself and that there were no chaotic clumps in the region of muscle fiber convergence. The pars marginalis of the orbicularis oris muscle connects with the deep buccinators muscle, which may account for how the pars marginalis fibers act to press the upper lip against the maxillary teeth or invert it closer to the oral cavity...

There is growing interest in conducting public health research using data from social media. In particular, Twitter "infoveillance" has demonstrated utility across health contexts. However, rigorous and reproducible methodologies for using Twitter data in public health are not yet well articulated, particularly those related to content analysis, which is a highly popular approach. In 2014, we gathered an interdisciplinary team of health science researchers, computer scientists, and methodologists to begin implementing an open-source framework for real-time infoveillance of Twitter health messages (RITHM)...

AIM: Patient's long-term phenomenology after first-episode psychosis could be blurred due to early intervention. The contradictory messages regarding necessity of long-term antipsychotic treatment derived from different methodologies warrants careful reappraisal. METHODS: We approached a group of patients lost to follow-up in a previous study. Targeting these 44 missing patients, we sent 2 carefully worded letters to invite them for interviews to see if their life trajectories were different from those who stayed in a university-based hospital system...

We examined whether potential help givers' future time perspective (FTP) accounts for the decision to give a person in need dependency-oriented help (i.e., providing the complete solution) or autonomy-oriented help (i.e., providing the means to solve a problem). In addition, building on past research on the effects of empathy in help giving decisions, the present research explored whether helpers' willingness to offer specific type of help is predicted by the interaction between FTP and interpersonal empathy...

Research on brain function after brachial plexus injury focuses on local cortical functional reorganization, and few studies have focused on brain networks after brachial plexus injury. Changes in brain networks may help understanding of brain plasticity at the global level. We hypothesized that topology of the global cerebral resting-state functional network changes after unilateral brachial plexus injury. Thus, in this cross-sectional study, we recruited eight male patients with unilateral brachial plexus injury (right handedness, mean age of 27...

Objective The sedative dexmedetomidine plays a role in multi-organ protection by inhibiting toll-like receptor (TLR) 4 expression in ischemia/reperfusion injury. The present study investigated whether the neuroprotective effects of dexmedetomidine could be blocked by the TLR4 agonist lipopolysaccharide. Methods We established a cerebral ischemia/reperfusion model in neonatal Sprague-Dawley rats through bilateral carotid artery occlusion for 20 minutes followed by a 2-hour reperfusion. Rats were assigned to four groups: Sham operation, ischemia/reperfusion, ischemia/reperfusion preceded by dexmedetomidine treatment (10 µg/kg), and ischemia/reperfusion preceded by dexmedetomidine (10 µg/kg) and lipopolysaccharide (500 µg/kg) treatments...
