ABSTRACT

OBJECTIVES@#To study the application value of transport ventilator in the inter-hospital transport of critically ill children.@*METHODS@#The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes.@*RESULTS@#There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05).@*CONCLUSIONS@#The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

ABSTRACT

Angong Niuhuang Pills(AGNHP) are effective in clearing heat, removing the toxin, and eliminating phlegm for resuscitation. Clinically, it is widely used to treat various diseases such as febrile convulsion due to heat attacking pericardium, but its therapeutic effects on heart failure(HF) have not been well recognized. In this study, the profiles of differential metabolites regulated by AGNHP were identified by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS). The underlying mechanism of AGNHP against HF was illustrated based on the integrated analysis of pharmacological data and metabolic molecular network. The HF model was induced by isoproterenol in mice. After oral administration of AGNHP for one week, cardiac functions in HF mice were evaluated by echocardiography, and serum samples of mice were collected for metabolomics analysis. Eight differential metabolites of AGNHP against HF were screened out through partial least square discriminant analysis(PLS-DA) and input into MetaboAnalyst for the analysis of metabolic pathways. Moreover, the critical metabolic pathways regulated by AGNHP were enriched according to the potential targets of major compounds in AGNHP. After AGNHP treatment, the recovered index of relative content of some metabolites underwent cross-scale fusion analysis with therapeutic efficacy data, followed by "compound-reaction-enzyme-gene" network analysis. It is inferred that the anti-HF effects of AGNHP may be attributed to the metabolism of arachidonic acid, amino acid, glycerophospholipid, and linoleic acid. The cross-scale polypharmacological analysis method developed in this study provides a new method to interpret scientific principles of AGNHP against HF with modern technologies.

ABSTRACT

The discovery of active constituents of traditional Chinese medicine(TCM) faces multiple challenges, such as limited approaches to evaluate poly-pharmacological effects, and the lack of systematic methods to identify active constituents. Aimed at these bottleneck problems in the field, the present study intensively discussed the key scientific problems in the identification of active constituents of TCM, based on scientific methodologies including systematology, information theory, and synergetics. A comprehensive strategy is herein proposed to investigate the correlations between the chemical composition and biological activities of TCM, from macro-, meso-, and micro-scales. Moreover, in this study, we systematically proposed the methodology of the multimodal identification of TCM active constituents, and thoroughly constructed its core technologies. Its technical framework is suggested to be assessed by multimodal information acquisition, centered on multisource information fusion, and focused on interaction evaluation. Furthermore, the core technologies for the multimodal identification of active constituents of TCM were developed in this study, which is according to the characteristics of the exchanges of between TCM and biological organisms, in the aspects of material, energy and information. Finally, two examples of the application of the proposed method were briefly introduced. The proposed methodology provides a novel way to solve the bottlenecks in the study of active constituents of TCM, and lays the foundation for the multimodal study of TCM.

ABSTRACT

The Concurrent treatment of the brain and heart (CTBH) theory is proposed based on traditional Chinese medical theory and clinical practice. In this study, a framework for the pharmacological research platform was established to investigate the principles of concurrent treatment of the brain and heart. The platform for CTBH includes several key techniques for network modeling, discovery of active substances, dissecting mechanism of action and investigation of pharmacokinetic property of TCM. Taking network modeling of CTBH as an example, using database search, literature mining, network construction and module analysis, the that network modules closely associated with the pathological progress of cardiovascular and cerebrovascular diseases were identified, while further functional enrichment analysis of these modules indicated that the key biological processes included oxidative stress, metabolism and inflammation. GSK3B, NOTCH1, CDK4 were identified as key nodes in these network modules. The above-mentioned platform was applied to construct component-biomolecules network of Danhong injection for the identification of common targets and pathways. Among them, GSK3B had the highest correlation with the composition of Danhong injection in the network, and the biological function of whose cluster was related to cell oxidative stress. Based upon results of network analysis, validation experiments suggested that Danhong injection significantly improved the survival rate of oxidative injured myocardial cells and nerve cells, and the protective effect was related to the increase of phosphorylated GSK3β protein expression. Moreover, extracts of Salviae Miltiorrhizae Radix et Rhizoma and Carthami Flos exerted the synergisticcytoprotective effect. The results indicated that the mechanism of treatment of cardiovascular and cerebrovascular diseases of Danhong injection could be studied through network modeling and other methods. In summary, the proposed pharmacological platform provided a feasible way for revealing the mechanism of CTBH by using modern scientific methods.

ABSTRACT

Fluorescent bio-probes have attracted increasing attentions in studies for screening bioactive compounds from traditional Chinese medicines. In this study, a new-type fluorescent probe with the function of aggregation-induced emission (AIE) was used to screen dipeptidyl peptidase-4 (DPP-4) inhibitor from Xiaokean formula, which has been clinically used for the treatment of type 2 diabetes mellitus. Potential DPP-4 inhibitors were screened by the fluorescent probe, with diprotin A as the positive control; totally 43 components were isolated from Xiaokean formula by systematic separation. The results showed that 13 components can exert inhibitory effects on DPP-4 activity; 16 compounds were further identified by liquid chromatography-mass spectrometry (LC-MS) from those active components. The inhibitory effects of 14 compounds were further verified, while five of them showed significant inhibition against DPP-4. Salvianolicacid C, ginsenoside Rg₅ and timosaponin AI inhibited DPP-4 activity at the concentration of 5-50 μmol•L⁻¹ in a dose-dependent manner. Thus, our study provided a successful example for screening bioactive compounds from traditional Chinese medicines by using a novelfluorescent probe.

ABSTRACT

In this study, we focused on the study of pharmacodynamic effects for 6 major bioactive lignans of Schisandra chinensis, namely deoxyschizandrin, schisandrin B, schisandrin C, schisandrin, schizandrol B and schisantherin A. A compound-gene-pathway network, which contained 124 related genes and 88 pathways, was constructed by collecting drug genes through mining relevant literatures and network pharmacology analysis. Based on the network analysis, 32 pathways and 80 related genes were associated with inflammation, which implied that anti-inflammatory might be the major pharmacodynamic effects of these compounds. All lignans except schizandrol B reduced LPS-induced NO production in RAW264.7 cells, which validated the anti-inflammatory hypothesis generated from network analysis. Furthermore, we investigated the effects of deoxyschizandrin, schisandrin C, schisandrin and schisantherin A on the secretion of inflammatory cytokines TNF-α, IL-1β, IL-6, PGE2 and protein expressions of iNOS, COX-2. As a result, deoxyschizandrin showed the strongest anti-inflammatory activity with inhibitory effect on all 4 inflammatory cytokines secretions and protein expressions of iNOS, COX-2. This study provided evidences for systematic exploration on the pharmacolgical actions and mechanisms of schisandra.

ABSTRACT

Retinal vein occlusion (RVO) is a common clinical disease causing vision loss. Risk factors such as diabetes, atherosclerosis are closely associated with RVO. Xuesaitong injection is used extensively in clinical treatment of RVO, however the mechanism is still unclear. In this study, we investigated the protective effect of Xuesaitong injection on RVO rat model. Using a compound-target network of Xuesaitong on anti-RVO constructed by literature mining, we aim to elucidate the multi-compound, multi-target effect of Xuesaitong injection. Fifteen potential targets of Xuesaitong injection associated with inflammation, angiogenesis, apoptosis, and coagulation were identified in this study. VEGF, IL-1beta and IL-6, three important targets in the compound-target network were further experimentally validated. This study provided experimental evidence for Xuesaitong injection being effective in treating RVO and a network view on its anti-RVO mode of action through a multi-compound and multiple-target mechanism.

ABSTRACT

In this study, an approach based on triple-color fluorescence probes was developed for screening potential nephro-protective bioactive substances. Three fluorescent probes (i. e. FDA, MTR and Hoechst 33342) were used to label HK-2 cells injured by doxorubicin hydrochloride, and cellular fluorescence images were subsequently acquired and analyzed by a cellular-fluorescence image microscopy platform. The established method was applied to screening 53 components of Carthami Flos, and three components C17, C18 and C19 were found to exhibit nephroprotective effects against doxorubicin hydrochloride induced injury on HK-2 cells. Eight compounds (i. e. hydroxysafflor yellow A, 6-hydroxykaempferol-3-O-rutinoside-6-O-glucoside, 6-hydroxykaempferol-3,6-di-O-gluco-side or 6-hydroxykaempferol-6, 7-di-O-glucoside, 6-hydroxykaempferol-3-O-rutinoside, 6-hydroxykaempferol-3-O-glucoside or 6-hydroxykaempferol-7-O-glucoside, rutin, isoquercetin, and kaempferol-3-O-rutinoside) in components C17, C18 and C19 were preliminarily identified by liquid chromatography-mass spectrometry (LC-MS). Isoquercetin, rutin, kaempferol-3-O-rutinoside, and hydroxysafflor yellow A were confirmed by comparing with reference substances, Further study indicated that these four compounds had moderate nephroprotective effects, while isoquercetin showed a significant nephroprotective effect in a dose-dependent manner. These results suggest that isoquercetin, rutin, kaempferol-3-O-rutinoside and hydroxysafflor yellow A might be the nephroprotective bioactive substances in Carthami Flos.

ABSTRACT

This study developed a method for rapid screening neuroprotective compounds with FDA (fluorescein diacetate) labeled SH-SYSY cells, which was injuried by Glu (L-glutamic acid). The cell viability was determined by fluorescence automatic mi-croscopy screening system. Then, neuroprotective components from Gegen Qinlian decoction were screened by the proposed method. The results demonstrated that 4 chemical components, C15, D06, D07 and E05 from Gegen Qinlian decoction, showed significantly neuroprotective effects. Furthermore, 8 compounds (i. e. daidzin, 3'-methoxydaidzin, liquiritin apioside, 6-C-L-alpha-arabinopyranosyl-8-C-beta-D-glucopyranosyl chrysin, isoliquiritin apioside, baicalin, oroxylin-A-7-O-fP-D-glucuronide and wogonoside) were identified from these active components by LC-Q/TOF-MS technology (liquid chromatography quadrupole time of flight tandem mass spectrometry). These 8 compounds may be the potential neuroprotective substances in Gegen Qinlian decoction.

ABSTRACT

Zhishi Xiebai Guizhi Tang (ZSXBGZT), a famous traditional Chinese formula from Synopsis of Golden Chamber, composing of five herbal medicines, has been routinely used for the therapy of cardiovascular diseases in clinical. However, the active components of ZSXBGZT have not been investigated thoroughly. A reliable cell model was established by H2O2-induced injury in neonatal rat cardiomyocytes (NRCMs), with fluorescein diacetate (FDA) labelling the live cells, to screen cardioprotective substances. Seven components were found to have obvious cardioprotective effects through screening ZSXBGZT, Vc as the positive control. Eleven compounds were identified by liquid chromatography-mass spectrometry (LC-MS) from the active components C18, D14, D15, D16 and E09, and 6 of them were investigated further, which showed that hesperidin, neohesperidin and eriodictyol could protect NRCMs from H2O2-induced injury. In particular, eriodictyol showed significant cardioprotective effects in a dose-response relationship.
