Screening crucial lncRNAs and genes in osteoarthritis by integrated analysis

Abstract Background Osteoarthritis (OA) is one of the most frequent chronic diseases with high morbidity worldwide, marked by degradation of the cartilage and bone, joint instability, stiffness, joint space stenosis and subchondral sclerosis. Due to the elusive mechanism of osteoarthritis (OA), we aimed to identify potential markers for OA and explore the molecular mechanisms underlying OA. Methods Expression profiles data of OA were collected from the Gene Expression Omnibus database to identify differentially expressed mRNAs (DEmRNAs) and differentially expressed lncRNAs (DElncRNAs) in OA. Functional annotation and protein-protein interaction (PPI) networks were performed. Then, nearby DEmRNAs of DElncRNAs was obtained. Moreover, GO and KEGG pathway enrichment analysis of nearby DEmRNAs of DElncRNAs was performed. Finally, expression validation of selected mRNAs and lncRNAs was performed by quantitative reverse transcriptase-polymerase chain reaction. Results In total, 2080 DEmRNAs and 664 DElncRNAs were determined in OA. PI3K-Akt signaling pathway, Endocytosis and Rap1 signaling pathway were significantly enriched KEGG pathways in OA. YWHAB, HSPA8, NEDD4L and SH3KBP1 were four hub proteins in PPI network. The AC093484.4/TRPV2 interact pair may be involved in the occurrence and development of OA. Conclusion Our study identified several DEmRNAs and DElncRNAs associated with OA. The molecular characters could provide more information for further study on OA.

Advances in antiviral research of adaptor-associated protein kinase 1 (AAK1) inhibitors / 药学学报

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

Advance in Home-based Rehabilitation after Spinal Cord Injury (review) / 中国康复理论与实践

Home-based rehabilitation can effectively reduce the clinical complications of patients with spinal cord injury and accelerate the recovery of neurological function, as well as reduce the heavy economic burden on healthcare system. Home-based rehabilitation has shown effectiveness in multiple studies. Neurofeedback could relieve the neuropathic pain of 40% home patients with spinal cord injury. Wearable technology could monitor and promote the recovery of hand motor function. Household portable stimulators and surface electrodes could inhibit unnecessary bladder activity and improve urinary incontinence. Strengthening stretching training at home could reduce shoulder pain in patients with chronic spinal cord injury. Using functional electrical stimulation at home could improve the muscle function of patients with spinal cord injury due to loss of neurotrophic muscle atrophy. There are still some disadvantages of home-based rehabilitation, such as complicated operation, expensiveness and not convenient to carry for training equipment, which need to be further developed.

Comprehensive treatment for multicentric giant cell tumors of the pelvis and spine using apatinib: A case report and literature review

Background: There are no standardized treatments for giant cell tumors of the bone (GCTB) in rare locations such as the spine and pelvis or for those that are inoperable and recurrent, let alone for multicentric GCTB. This study reports a novel case of multicentric GCTB treated with a promising antiangiogenic drug, apatinib, a small-molecule tyrosine kinase inhibitor. The efficacy of apatinib in the treatment of GCTB has not been reported previously. Patients and Methods: A 27-year-old female presented with two giant cell tumors of the spine and sacrum–ilium diagnosed on December 15, 2016. Surgery and selective arterial embolization (SAE) were not reasonable options for this patient, and denosumab was unavailable; therefore, the antiangiogenic drug apatinib and the osteoclast inhibitor zoledronic acid were administered. Apatinib was initially administered at a dose of 850 mg daily, which was decreased to 425 mg daily after 7 months, and then increased again to 635 mg after 11 months. The patient was prescribed a maintenance dose of 500 mg daily after 16 months. The patient reported side effects of Grades I–III nausea, vomiting, and Grades II–III hand–foot syndrome. The patient underwent SAE at 26 months, and at that time, she was switched to denosumab instead of zoledronic acid. Results: The patient showed noticeable symptomatic improvement and visibly reduced tumor size after the first month of treatment. Computed tomography in the 4th month identified a partial response based on the RECIST criteria. The patient has achieved an objective reduction in tumor size at 32 months. Conclusions: Comprehensive treatment including apatinib represents a potential new treatment strategy for inoperable GCTB, with tolerable side effects. However, further clinical trials are now necessary to confirm an effective dose and determine the efficacy and safety of apatinib in the treatment of GCTB

MicroRNA-4290 suppresses PDK1-mediated glycolysis to enhance the sensitivity of gastric cancer cell to cisplatin

The development of chemotherapy resistance significantly impairs the efficiency of chemotherapy, but the underlying mechanisms of chemotherapy resistance in gastric cancer (GC) are complicated and still need to be further explored. Here, we aimed to reveal the effects of miR-4290/PDK1 (pyruvate dehydrogenase kinase 1) axis on chemotherapy resistance of GC in vitro. The expression patterns of miR-4290 in GC tissues and cell lines were determined by real-time quantitative PCR. Kaplan-Meier was used to assess the relationship between miR-4290 expression levels and patients' overall survival. CCK-8 and flow cytometry technologies were applied to detect cell proliferation and apoptosis. The luciferase gene reporter assay was used to evaluate the interaction between miR-4290 and PDK1. miR-4290 was lowly expressed in GC tissues and cell lines, which was closely associated with the shorter overall survival of GC patients. miR-4290 mimics significantly inhibited cell proliferation and induced cell apoptosis, as well as induced a significant reduction in the expression of PDK1. Moreover, miR-4290 significantly inhibited glycolysis and decreased the IC50 value to cisplatin in SGC7901 cells, whereas these effects were abolished and cell apoptosis was promoted when PDK1 was overexpressed. In conclusion, this study revealed that miR-4290 suppressed PDK1-mediated glycolysis to enhance the sensitivity of GC cells to cisplatin.

The research progress on the mechanism of adenosine A1 receptor-mediated calcitonin gene-related peptide to relieve migraine

Currently, the pathogenesis of migraine is unclear. The trigeminal vascular reflex theory is the dominant pathogenesis theory, and its core parts are neurogenic inflammation and pain sensitisation. Calcitonin gene related peptide (CGRP) is the most powerful vasodilating peptide in brain circulation. It is also a marker of trigeminal nerve microvascular activation that plays a synergistic role in the pathogenesis of migraine. Adenosine A1 receptor (A1R) can inhibit the release of CGRP in the trigeminal nerve vascular system to alleviate migraine by mediating adenosine. This review summarises the progress of research on the alleviation of migraine by using A1R-mediated CGRP.

OBJECTIVE@#To use the cone-beam computed tomography (CBCT) to evaluate the three-dimensional (3D) changes of maxillary landmarks in the maxillary protraction with alternating rapid palatal expansion and constriction and with rapid palatal expansion, and to provide some clinical suggestions for the early treatment of Class III malocclusion.@*METHODS@#A total of 36 maxillary retrusive patients were included and randomized in a 1:1 ratio to either the intervention group (alternating rapid palatal expansion and constriction group, RPE/C) or the control group (rapid palatal expansion group, RPE). Randomization was accomplished with permuted block randomization based on participation sequence. The patients in the RPE/C were treated for 10 weeks (0.5 mm/d) with the repetition of two-week palatal expansion and two-week palatal constriction. The patients in the RPE were taught to complete rapid palatal expansion for 2 weeks (0.5 mm/d ). The patients were instructed to come to the office for the follow-up to ensure the correct procedures. Damaged expanders were repaired (or replaced) and rebanded quickly. Sequential CBCT images including pretreatment (T1), post-expansion (T2) and post-protraction (T3) were required for 3D reconstruction, establishment of landmarks, measurement and analysis by Mimics 10.01.@*RESULTS@#There was significant forward movement of subspinale (A) in the RPE/C after the treatment with (3.06±1.29) mm, compared with RPE (2.16±1.27) mm, P<0.05. There were more symmetrical changes of the landmarks in the RPE/C and there was no statistic significance of the entire treatment time between the two groups. Moreover, the maxillary skeletal landmarks had the following 3D changes of a forward and downward movement during the expansion stages T2-T1, a forward and upward movement during the protraction stages T3-T2 and a forward and downward movement during the total treatments T3-T1 compared with the control group. And the width between the bilateral landmarks increased during the expansion stages T2-T1, narrowed down during the protraction stages T3-T2 and increased during the total treatments T3-T1.@*CONCLUSION@#The maxillary protraction with alternating rapid palatal expansion and constriction provided clinical benefits on maxillary advancement and symmetrical changes in the orthopedic treatment of the patients with maxillary retrognathism and it required further study on the orthodontic analysis and measurements of CBCT.
