Background

Spinal cord injury (SCI) is a devastating disease with no clear molecular mechanisms or effective treatments. Murine models of SCI have been widely used to explore its pathogenesis.

Methods

In this study, a comprehensive bioinformatic analysis using GEO datasets was performed to evaluate the characteristics of different SCI models.

Results

We found that the contusion model was similar to the compression model, with inflammation and apoptosis significantly enriched, while more complex biological processes existed in hemisection and transection model. Inflammatory markers can be used as a primary evaluation index of SCI models not only in the acute and subacute phases, but also in the chronic phase. In the meantime, apoptosis markers are more suitable for evaluating mouse SCI models while inflammatory markers are more suitable for rat SCI models. In addition, SCI models with different ages, genders, injury positions, and injury levels were also analyzed.

Conclusion

Our findings indicate that SCI is a heterogeneous disease and play an instructive role in model selecting.

Chiari malformation (CM) is a type of disease in which the cerebellar tonsils extend downward due to abnormal development of the hindbrain. Still, recent bibliometric studies on CM are a blind spot. We conducted a bibliometric analysis of research over the past decade to explore the hot spots and trends in this field. We used VOSviewer, CiteSpace and Bibliometrix to perform a global bibliometric analysis of the articles from 2013 to 2022 on CM in the web of science (WOS) core collection. The query identified 2155 articles, of which most were published in the USA. Institutions like Akron University and the University of Washington published the most articles and were widely cited. Loth Francis and R. Shane Tubbs were the most productive authors on this topic. Besides, the top-cited article was also published by R.Shane Tubbs in J NEUROSURG-PEDIATR (2011). A great number of relevant studies focused on syringomyelia and surgical technique such as posterior fossa decompression. The CM field is still heating up and will continue to grow in popularity. Our findings offer a panoramic view of this research field for new researchers and policymakers.

Transcriptome alterations and therapeutic drugs in different organs after spinal cord injury based on integrated bioinformatic analysis

Objective

To identify transcriptomic alterations and therapeutic drugs in different organs after spinal cord injury via comprehensive bioinformatics analyses.

Methods

RNA-sequencing data of the soleus muscle, bladder, liver, raphe, and sensorimotor cortex areas in various rat spinal cord injury models were obtained from the Gene Expression Omnibus database for bioinformatics analysis. Then, the common pathways and biological pathway changes in multiple organs were identified.

Results

By comparing the enrichment results of differentially expressed genes, inflammatory response and lipid metabolism were found to be significantly altered in multiple organs. The MAPK signaling pathway was a key pathway in the abovementioned biological processes. In addition, autonomous repair was observed in each organ. Finally, pharmacological analysis showed that coenzyme A might be an effective drug.

Conclusion

Coenzyme A is a candidate treatment drug for spinal cord injury. Hence, in addition to the current mechanisms targeted by anti-inflammatory approaches, lipid metabolism can also be a treatment target for spinal cord injury.
