The traditional efficacy of traditional Chinese medicine (TCM) is to summarize the clinical efficacy of TCM under the guidance of TCM theory,and it possess important guiding significance for the clinical use of TCM.Comparing with the modern medical system,the TCM system was different from western medicine in diagnosis and treatment modes,and the disease targets of TCM maybe more extensive than that of western medicine.Based on the traditional efficacy of TCM,combined with modern means of science and technology,the research on material basis and pharmacological mechanism of TCM was beneficial to discovery the new targets,new mechanism,new material and the secondary development of new drug of TCM.Furthermore,it also has far-reaching significance on interpret the modern scientific connotation of TCM efficacy.Therefore,deriving from the traditional efficacy of TCM,the research of modern pharmacodynamic material basis is the source for original research.

OBJECTIVE To investigate the effects of different drying methods on the index components in wine-processed Cornus officinalis so as to optimize drying method.METHODS After processed with wine， C. officinalis decoction pieces were dried with different drying methods （blast drying， far infrared drying， microwave drying， freeze drying， sun drying， shade drying and combined drying）. The contents of 5 components such as gallic acid in wine-processed C. officinalis were determined by high- performance liquid chromatography. The contents of total flavonoids in wine-processed C. officinalis were determined by chromogenic method. Analytic hierarchy process was used to evaluate the effects of different drying methods on the contents of components in C. officinalis.RESULTS The contents of gallic acid， 5-hydroxymethylfurfural， monoside， loganin， cornuside and total flavonoids in 22 batches of wine-processed C. officinalis were 1.043 8-1.563 8， 0.648 5-2.358 8， 5.031 0-10.305 7， 6.681 2- 7.534 2， 0.986 5-1.148 8 and 33.657 2-50.741 5 mg/g， respectively. The comprehensive scoring results of analytic hierarchy process showed that the comprehensive score of each component in C. officinalis dried by microwave at 75 ℃ was higher ， followed by blast drying at 60 ℃ and far infrared drying at 60 ℃ .CONCLUSIONS The wine-processed C. officinalis could be dried by microwave drying at 75 ℃， blast drying at 60 ℃ or far infrared drying at 60 ℃.

Pulmonary endothelial barrier dysfunction is a hallmark of clinical pulmonary edema and contributes to the development of acute lung injury (ALI). Here we reported that ruscogenin (RUS), an effective steroidal sapogenin of Radix Ophiopogon japonicus, attenuated lipopolysaccharides (LPS)-induced pulmonary endothelial barrier disruption through mediating non-muscle myosin heavy chain IIA (NMMHC IIA)‒Toll-like receptor 4 (TLR4) interactions. By in vivo and in vitro experiments, we observed that RUS administration significantly ameliorated LPS-triggered pulmonary endothelial barrier dysfunction and ALI. Moreover, we identified that RUS directly targeted NMMHC IIA on its N-terminal and head domain by serial affinity chromatography, molecular docking, biolayer interferometry, and microscale thermophoresis analyses. Downregulation of endothelial NMMHC IIA expression in vivo and in vitro abolished the protective effect of RUS. It was also observed that NMMHC IIA was dissociated from TLR4 and then activating TLR4 downstream Src/vascular endothelial cadherin (VE-cadherin) signaling in pulmonary vascular endothelial cells after LPS treatment, which could be restored by RUS. Collectively, these findings provide pharmacological evidence showing that RUS attenuates LPS-induced pulmonary endothelial barrier dysfunction by inhibiting TLR4/Src/VE-cadherin pathway through targeting NMMHC IIA and mediating NMMHC IIA‒TLR4 interactions.
