BACKGROUND:In the whole world, spinal cord injuries caused by trauma lead to more than 180 000 people presenting with permanent impairment annualy. A large number of experiments have confirmed in recent years, under physiological conditions, microRNA has specific expression and plays an important role in the nervous system. OBJECTIVE: To discuss the changes in microRNA expression induced by injuries as wel as the pathophysiological significance in spinal cord injury, and to explore the development potential of microRNA in tissue-engineered and clinical repair of spinal cord injury. METHODS:A computer-based search of PubMed and Chinese Journal Database was performed for related articles published from January 2000 to December 2014 using the keywords of “SCI, microRNA, transcriptional control, clinical research progress” in English and Chinese. Finaly, 38 articles were included for result analysis. RESULTS AND CONCLUSION: Mechanical injury initialy triggers a series of complex secondary damages, including nervous, vascular and immune systems, which can influence the severity of spinal cord injury to a great extent. Secondary damage to the spinal cord is mainly attributed to the activation and deactivation of some specific genes associated with celular and biochemical mechanisms, such as cysteine aspartate specific protease (caspase) gene family, apoptosis related protein Fas and its ligand Fasl system, P53 gene, apoptosis related gene Bcl-2 family. Recent studies have proved that the functional activation of microRNA expression is the key to spinal cord injury. With the development of biological information engineering, studies and controling technologies associated with microRNA expression have been gradualy dominated, some clinical application based on microRNA technology has entered the clinical trial stage. It is believed that with the continuous development of technology and decrease of cost, permanent dysfunction due to spinal cord injury can be regulated and repaired through the microRNA technology at gene level in the future.

Objective To investigate the effect of high mobility group box-1 protein (HMGB1) on inter-leukin-2 (1L-2) and interleukin-2 receptor α (IL-2α) expressions in human T lymphocytes and its potential regulat-ing mechanism in vitro. Method Human T lymphocytes were isolated and suspended, the cells were cultured with 20 μg/mL phytohemagglutinin (PHA) in 5% CO_2 at 37 ℃, recombinant human HMGB1 (rhHMGB1, 0, 10, 100, 1000 ng/mL) was added with the PHA and cultures were centrifuged at 12 and 48 hours for cell collect-ing. Reverse transcription polymerase chain reaction (RT-PCR) amplification was perfomed to determine gene ex-pressions of IL-2, IL-2Rα. IL-2, sIL-2R protein levels in cell culture supematants were measured by ELIZA. Re-sults After coincubated with rhHMGB1 (10, 100, and 1000 ng/mL) for 12 hours, IL-2 levels in cell culture su-pernatants respectively were 0 . 064 ± 0. 017 μg/L, 0.076±0.033 μg/L, and 0.061 ±0.02 μg/L, which were significantly higher compared with the untreated cells (0.045±0.011 μg/L, P < 0.05 or P < 0.01). Mean-while, IL-2 mRNA expression was markedly up-regulated following rhHMGB1 stimulation in various doses (F = 4.6872, P < 0.01). At 48 bourn, however, both IL-2 mRNA expression and protein production tended to de-crease along with an increased dose of dd-IMGB1 stimulationn. IL-2/sIL-2R ratio in 1000 ng/mL rhHMGB1 was markedly lower than that in 10 ng/ml rhHMGB1 (0.036±0.015 vs.0.055±0.017, P <0.05), together with down-regulation of IL-2Rα mRNA expression(P <0.01). Conclusions These data indieated that HMGBI could marked influence the IL-2/IL-2R expression in human T lymphocytes. With the increase in stimulating doses and prolongation of time, HMGBI might down-regulate T cell-mediated immune response of human lymphocytes.

Objective To explore the preventive and protective effect of CGRP on focal cerebral infarction in rats.Methods Focal cerebral infarction model was made by photochemical reaction. The level of cerebral edema was assayed by measuring brain water content.Nervous system evaluation was scored by the method of Ohno, Bederson, LeWay standard. The volume of cerebral infarction and its location were determined by TTC staining.Results CGRP has significant preventive and protective effect to focal cerebral infarction which showed the nervous system scores took a favourable turn, brain edema descended and infarction volume reduced. This effect was related with the dose and the way of administration of CGRP. A single dose (1.33 BU/gBW) of CGRP didn't have significantly effective.It should be given for at least over 2 days. This protective effect did not increase when the dose increased to a certain level. As for the effect of the way of administration of CGRP, multiadministration of fewer doses CGRP was better while the total dose kept constantly.Conclusion CGRP has definite preventive and protective effect to focal cerebral infarction in rats.It has also better effective in inhibition of brain edema. However its dose should be confined in a proper level.
