Transcriptome Sequencing of CeRNA Network Constructing in Status Epilepticus Mice Treated by Low-Frequency Repetitive Transcranial Magnetic Stimulation.

It is shown that great progress was recently made in the treatment of repetitive transcranial magnetic stimulation (rTMS) for neurological and psychiatric diseases. This study aimed to address how rTMS exerted it therapeutic effects by regulating competitive endogenous RNAs (ceRNAs) of lncRNA-miRNA-mRNA. The distinction of lncRNA, miRNA and mRNA expression in male status epilepticus (SE) mice treated by two different ways, low-frequency rTMS (LF-rTMS) vs. sham rTMS, was analyzed by high-throughput sequencing. The Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were carried out. Gene-Gene Cross Linkage Network was established; pivotal genes were screened out. qRT-PCR was used to verify gene-gene interactions. Our results showed that there were 1615 lncRNAs, 510 mRNAs, and 17 miRNAs differentially which were expressed between the LF-rTMS group and the sham rTMS group. The expression difference of these lncRNAs, mRNAs, and miRNAs by microarray detection were consistent with the results by qPCR. GO functional enrichment showed that immune-associated molecular mechanisms, biological processes, and GABA-A receptor activity played a role in SE mice treated with LF-rTMS. KEGG pathway enrichment analysis revealed that differentially expressed genes were correlated to T cell receptor signaling pathway, primary immune deficiency and Th17 cell differentiation signaling pathway. Gene-gene cross linkage network was established on the basis of Pearson's correlation coefficient and miRNA. In conclusion, LF-rTMS alleviates SE through regulating the GABA-A receptor activity transmission, improving immune functions, and biological processes, suggesting the underlying ceRNA molecular mechanisms of LF-rTMS treatment for epilepsy.

Effect of High-Frequency Repetitive Peripheral Magnetic Stimulation on Motor Performance in Intracerebral Haemorrhage: A Clinical Trial.

OBJECTIVES: The aim of the randomized, double-blind, sham-controlled trial was to explore the efficacy and safety of HF-rPMS synchronosly applied to the axilla (stimulating the brachial plexus) and the popliteal fossa (stimulating the tibial nerve and common peroneal nerve) in patients with intracerebral hemorrhage on rehabilitation of motor functions. MATERIALS AND METHODS: Patients with intracerebral haemorrhage in the early period were recruited and randomly assigned to the HF-rPMS group or the sham rPMS group. The two synchrous coils of magnetic stimulation in the two groups were respectively applied to the axilla and the popliteal fossa of the affected limb. But the sham group received the ineffective rPMS and only heard the sound as occured in the HF-rPMS group. Clinical outcomes included the change of Fugl-Meyer Assessment (FMA) scale and Medical Research Council (MRC) scale before and after HF-rPMS. RESULTS: Of 76 eligible patients, 30 were included and only 26 patients completed this study. The diferences on the improvement of the upper extremity FMA (P=0.012), the lower extremity FMA (P=0.001), the proximal MRC of upper extremity (p = 0.043), the proximal MRC of lower extremity (p= 0.004) and the distal MRC scores of lower extremity (p= 0.008) between the the HF-rPMS group and sham rPMS group were statistically signifcant. CONCLUSIONS: Synchrous HF-rPMS intervention at the axilla and the popliteal fossa significantly improved motor function and proximal muscle strength of upper and lower limb of patients in acute or early subacute phase of intracerebral hemorrhage.

A case series: 3-dimensional computed tomographic study of the superior orbital vessels: Superior orbital arcades and their relationships with the supratrochlear artery and supraorbital artery.

BACKGROUND: Vascular complications from periorbital intravascular filler injection are major safety concerns. OBJECTIVE: To thoroughly describe the superior orbital vessels near the orbital rim and propose considerations for upper eyelid and forehead injections. METHODS: Fifty-one cadaver heads were infused with lead oxide contrast media through the external carotid artery, internal carotid artery, and facial and superficial temporal arteries. Computed tomography (CT) images were obtained after contrast agent injection, and 3-dimensional CT scans were reconstructed by using a validated algorithm. RESULTS: Eighty-six qualified hemifaces clearly showed the origin, depth, and anastomoses of the superior orbital vessels, which consistently deployed 2 distinctive layers: deep and superficial. Of all hemifaces, 59.3% had deep superior orbital vessels near the orbital rim, including 44.2% with deep superior orbital arcades and 15.1% with deep superior orbital arteries, which originated from the ophthalmic artery. Additionally, 97.7% of the hemifaces had superficial superior orbital arcades, for which 4 origins were identified: ophthalmic artery, superior medial palpebral artery, angular artery, and anastomosis between the angular and ophthalmic arteries. LIMITATIONS: The arterial depth estimated from 3-dimensional CT needs to be confirmed by standard cadaver dissection. CONCLUSION: This study elucidated novel arterial systems and proposed considerations for upper eyelid and forehead injections.
