Analysis of pharmacological mechanisms of Yinyanghuo as treatment of erectile dysfunction with network pharmacology-based strategy

Erectile dysfunction is considered an important health problem that impacts the quality of life of men. Yinyanghuo, also called Epimedium or Horny Goat Weed, is a frequently used Chinese traditional herbal medicine, commonly used in treating erectile dysfunction in China. A network pharmacology method was performed systematically, at a molecular level, to analyse the pharmacological mechanism of Yinyanghuo as erectile dysfunction therapy. The network pharmacology method used in this study primarily includes prescreening of the active compounds, prediction of targets, network analysis and gene enrichment analysis. This network analysis proved that 4 targets (AR, NR3C2, PDE5A and BMP2) could be the targets of Yinyanghuo therapy on erectile dysfunction. Besides, gene enrichment analysis predicted that Yinyanghuo might have a role in erectile dysfunction by regulating 10 molecular functions, 8 cellular components, 10 biological processes and 36 possible targets related to 10 signalling pathways. Our study demonstrated the molecular and pharmacological mechanisms of Yinyanghuo against erectile dysfunction with a holistic approach and demonstrated a powerful method for analysing pharmacological mechanisms and rational utilisation of Traditional Chinese Medicine clinically.     

Adult Trauma Patients with Autism Spectrum Disorder: A Case-Control Study to Evaluate Disparities After Injury

BackgroundAdult trauma patients with autism spectrum disorder (ASD) may have distinct care needs that have not been previously described. We hypothesized that due to differences in clinical care and disposition issues, injured adults with ASD would have increased lengths of stay, higher mortality, and increased rates of complications compared to adults without ASD.MethodsThe Pennsylvania Trauma Outcomes Study database was queried from 2010-2018 for trauma patients with ASD. Case-control matching was performed for two controls per ASD patient accounting for age, gender, injury mechanism, and injury severity score. Primary outcomes included length of stay, mortality, and complication rate. Univariate analysis compared presentation and clinical care between the two groups. Multivariate regression and Kaplan-Meier curves modeled length of stay. Significance was defined as p < 0.05.ResultsA total of 185 patients with ASD were matched to 370 controls. Age (mean +/- standard deviation) was 33.4 +/- 16.5 years. Gender was 81.1% male. Mechanisms were 88.1% blunt, 5.9% penetrating, and 5.9% burns. Significant clinical differences identified in patients with ASD vs. case-controls included presenting verbal GCS (median [IQR]) (5 [2] vs. 5 [0], p < 0.01), proportion of patients intubated at presentation (20.0% vs. 13.0%, p = 0.031), and hospital length of stay (4 [6] days vs. 3 [4] days, p = 0.002). Adult patients with ASD were less likely to be discharged home and more often discharged to a skilled nursing facility (p < 0.01). There were no differences in mortality, rates of complications, imaging, or operations. Multivariate regression analysis controlling for demographic and clinical differences revealed the diagnosis of ASD independently contributed 3.13 days (95% Confidence Interval: 1.85 to 4.41 days) to injured adults’ length of stay. Kaplan-Meier curves showed injured patients with ASD were less likely to be discharged than case-controls starting from time of admission (log rank test, p < 0.001).ConclusionsThis statewide analysis suggests injured patients with ASD have increased lengths of stay without other clinical or outcome differences. Given significant differences in discharge destination, these findings support early involvement of a multidisciplinary care collaborative. Further research is needed to identify factors that contribute to disparities in care for adults with ASD.

Simultaneous Construct Surface Microstructural and Internal Network-Like Conductive Pathways of Poly(l-lactic acid)/Carbon Nanomaterials Composite Foams

The poly(l -lactic acid) (PLLA)/carbon nanomaterials composite foams with hierarchical surface microstructural and internal conductive pathways are successfully prepared by a simple crystallization-assisted rapid phase separation (CARPS). The dimension and morphology of carbon nanomaterials can induce different crystallization forms to construct the hierarchical surface microstructure, and they are distributed on the phase interface of solvent and non-solvent to form conductive pathways. It is found that the heterogeneous nucleation of nanomaterials promotes a significant increase in crystallinity, and a stacked granular structure formed on the surface promotes the increase of the water contact angle to 148.7°. Foams with interconnecting pore structures contribute to the formation of 85.3% porosity and 12.33 g g⁻¹ oil absorption. Carbon nanomaterials are distributed on the pore walls of the porous foam, which converts the foam from an insulating material to a conducting polymer. Furthermore, the uniform distribution of nanomaterials significantly affects the thermal stability of the PLLA. In belief, the multifunctional biodegradable foam, prepared by a CARPS method, makes it promising for industrial production and has potential applications in electrical conductivity, oil-water separation, and many other fields.
