Objective: To explore the neuroprotective effects of the Shaoyao Gancao decoction (SGD) against excitatory damage in PC12 cells and the role of the Src-NR2-nNOS pathway mediation by SGD in regulating γ-aminobutyric acid (GABA)-glutamate (Glu) homeostasis. Methods: N-Methyl-d-aspartic acid (NMDA) was used to establish a PC12 cell excitability injury model. To investigate the neuroprotective effect of SGD, a cell counting kit-8 (CCK-8) assay was used to determine PC12 cell viability, Annexin V/Propidium Iodide (Annexin V/PI) double staining was used to determine PC12 cell apoptosis, and Ca2+ concentration was observed using laser confocal microscopy. GABA receptor agonists and antagonists were used to analyze the neuroprotective interactions between γ-aminobutyric acid (GABA) and NMDA receptors. Additionally, molecular biology techniques were used to determine mRNA and protein expression in the Src-NR2-nNOS pathway. We analyzed the correlations between the regulatory sites of GABA and NMDA interactions, excitatory neurotoxicity, and brain damage at the molecular level. Results: NMDA excitotoxic injury manifested as a significant decrease in cell activity, increased apoptosis and caspase-3 protein expression, and a significant increase in intracellular Ca2+ concentration. Administration of SGD, a GABAA receptor agonist (muscimol), or a GABAB receptor agonist (baclofen) decreased intracellular Ca2+ concentrations, attenuated apoptosis, and reversed NMDA-induced upregulation of caspase-3, Src, NMDAR2A, NMDAR2B, and nNOS. Unexpectedly, a GABAA receptor antagonist (bicuculline) and a GABAB receptor antagonist (saclofen) failed to significantly increase excitatory neurotoxicity. Conclusions Taken together, these results not only provide an experimental basis for SGD administration in the clinical treatment of central nervous system injury diseases, but also suggest that the Src-NR2A-nNOS pathway may be a valuable target in excitotoxicity treatment.

Objective To evaluate the clinical application value of reflectance confocal microscopy(RCM) in the diagnosis of several common diseases manifesting as papules in children, including lichen nitidus, verruca planae, lichen striatus, milium, molluscum contagiosum and lichen pilaris. Methods A total of 579 children clinically characterized by papules were recruited into this study. RCM was used to observe lesions and perilesional normal skin. The RCM features of 6 diseases manifesting as papules were analyzed and compared. Results Based on RCM images, 236 patients were diagnosed with lichen nitidus, 70 with verruca planae, 123 with lichen striatus, 40 with milium, 53 with molluscum contagiosum and 57 with lichen pilaris. All the 6 diseases had typical RCM features. Concretely speaking, RCM images of lichen nitidus lesions showed infiltration of dense inflammatory cells and melanophages in enlarged dermal papillae. In RCM images of verruca planae lesions, cells in the granular and spinous layers were arranged in concentric circles, giving a rose cluster?like appearance. RCM images of lichen striatus lesions revealed focal swelling of stratum spinosum, absent or local liquifaction degeneration of basal cells, and clustering of a moderate number of inflammatory cells in the superficial dermis. In RCM images of milium lesions, well?circumscribed round or oval structures containing highly but nonuniformly refractive materials could be seen in the dermis. RCM images of molluscum contagiosum lesions showed intact cystoid structures containing highly refractive molluscum bodies. Lowly to moderately refractive cutin ? like materials were observed along with the dilation of hair follicle infundibula in RCM images of lichen pilaris lesions. In RCM images, the 6 diseases were distinguished mainly based on structural features(patterns and refractivity)of skin lesions shown by continuous vertical scanning. Conclusion RCM is of great value to the diagnosis of diseases manifesting as papules in children.
