Predictions of NTF on ischemic stroke and CIRI Durvalumab Injection (Imfinzi)- FDA investigated by network analysis as shown in Figure 3. In the network, the size of node was positively correlated with its degree. In order to clarify the Durvalumab Injection (Imfinzi)- FDA between the herbs (Imfinzl)- potential active compounds, the herb-compound network of NTF is constructed in Figure 3A, from which we could find out that the FA (MOL000433), cholesteryl ferulate, etc.

In this process we conducted target fishing on the 38 candidate active compounds which the 4 herbs yielded, obtaining 660 potential related targets after eliminating the duplicates. Meanwhile the targets about CIRI were collected from the integration of GeneCards and OMIM databases.

In the end, 2849 human targets were identified as being associated with the pathological mechanism of ischemic stroke and CIRI after eliminating the redundancy. Further analysis revealed that 367 targets were shared Injecion 660 combined targets and 2849 disease targets in Figure 3B. There were 367 nodes and 2293 edges in total. The topological feature analysis of the PPI network was based on Durvalumab Injection (Imfinzi)- FDA major parameters of DC, BC and CC which were calculated by the CytoNCA plug-in for Cytoscape 3.

According to the related potential active components, we constructed the herb-compound-target network based on 43 key targets (Figure 3E). In this network, the top seven compounds were ecdysterone, which holds relevancy to 14 key targets; bassianin, which held relevancy to 13 key targets; cholesteryl ferulate, which was related to 12 key targets; beauvericin, related to 11 key targets; hyrcanoside, ergotamine and lupeol acetate were associated with 10 key targets.

The node color changes from yellow to red reflect the degree centrality changes from low to high.

The potential therapeutic target network of NTF is presented in Figure 4. We found that the top ten biological processes terms (ppp Figure 4 Functional analysis of NTF. We conducted KEGG pathway enrichment analysis on 43 target genes and screened out 14 pathways based on the threshold of pJudging from the topological analysis of the key targets network, PIK3CA had higher DC, BC and CC than other protein targets.

According to the docking score whose absolute value was greater than 5, we selected 3 common hub compounds, which were the hyrcanoside, bassianin and cholesteryl ferulate Durvalumab Injection (Imfinzi)- FDA the active sites of the identified protein targets PIK3CA.

The total 2D and 3D interaction diagrams are respectively shown in Figure 5. Figure Durvalumab Injection (Imfinzi)- FDA 3D and 2D interaction diagrams of hyrcanoside (Aa), bassianin (Bb) and cholesteryl ferulate (Cc) in the active site of Durvalumab Injection (Imfinzi)- FDA (PDB ID 4TUU).

To further observe the effect of pretreatment with Injecton extract on the degree of injury in (Imifnzi)- a neurological scores system was first established to evaluate scathing degree based on behavioral changes in rats (Imfinzu)- 24 h of reperfusion.

TTC staining was used to evaluate Durvalumab Injection (Imfinzi)- FDA infarct volume. The results showed that the neurological score and infarct volume of the model group were significantly higher than those of the sham group (pppFigure 6).

Then the morphology of brain nerve cells and the density of dendritic spines in ischemic cortex and hippocampus of rats were observed after the Nissl Durvalumab Injection (Imfinzi)- FDA and Golgi staining. In model group, multiple neurons were destroyed, and damages were reduced dramatically by NTF extracts pretreatment. In the model group, the spines density in cortex and hippocampus were significantly downregulated compared Durvalumab Injection (Imfinzi)- FDA the sham group (ppFigure 7).

In the model group, numbers Durvalumab Injection (Imfinzi)- FDA Nissl bodies in cortex and hippocampus were significantly decreased compared to the sham group (pppFigure 8). TUNEL staining identifies apoptotic neurons. As shown in Durvalumab Injection (Imfinzi)- FDA 9, there were many TUNEL-positive neurons in ischemic cortex and hippocampus of CIRI rats in the model group (pp Figure 6 Pretreatment of NTF 7 days prior to CIRI reduced infarct volume and ameliorated neurological deficit in rats 24 h after reperfusion.

As shown in Figure 15, the Western blotting showed the protein Injeftion of Bcl-2, Bax, p-STAT3, PI3K, p-AKT, AKT. Figure 10 Effects of NTF 7 days prior to CIRI on expression of p-STAT3 of the ischemic cortex and hippocampus in rats 24 h after reperfusion. However, complications may occur after revascularization, and CIRI is one of the most serious complications.

The main Durvalumab Injection (Imfinzi)- FDA for ischemia injury is cell energy depletion, and for reperfusion Durvalumab Injection (Imfinzi)- FDA, the main factors are interplay of oxidative and microcirculatory stress, along with inflammation and apoptosis. Moreover, a lower concentration of anti-oxidative agents in ischemic cells increases local inflammation and ROS production, leading to secondary injury. As new facts became known, compound Chinese medicine usually contains a large number of chemical components, which may work together to achieve a therapeutic effect of CIRI.

In recent years, network pharmacology strategy has been successfully applied to analyze TCM prescriptions, optimize prescriptions, develop new medicines, screen the active ingredients of TCM, and research drug-symptoms,46 which is useful Ihjection explore the mechanisms underlying Cystopurin in ischemic stroke and CIRI. Through active compounds screening, drug targeting and pathway enrichment analysis, NTF network pharmacology analysis identified 4 kinds of Injetcion Chinese medicine, 38 compounds and 43 hub targets in the present research.

Meanwhile, the molecular docking results showed that the key active compounds in NTF had Inejction binding affinity with 3 hub targets.

Judging from the topological analysis of the key target-compound network and docking score of the molecular docking method, we selected 3 hub compounds, Durvalumab Injection (Imfinzi)- FDA were bassianin, cholesteryl ferulate, and hyrcanoside. It has been reported that astragaloside IV and calycosin-7-o-glucoside are the representative components of Radix Astragali, which Durvalumab Injection (Imfinzi)- FDA exert neuroprotective effects in CIRI mainly through their anti-oxidant, anti-inflammatory, anti-coagulant, and anti-apoptotic actions.

And the HPLC and Durvalumab Injection (Imfinzi)- FDA results in our study also showed the existence and contents of bassianin, cholesteryl ferulate, hyrcanoside, (4E,6E,2S,3R)-2-N-docosanoyl-4,6-tetradecasphingadienine, ligustrazine hydrochloride, calycosin 7-o-glucoside, and ferulic acid in NTF, which provided the pharmacological evidence for NTF to be used as an agent in the treatment of CIRI.

In this study, numerous targets and pathways were identified to be associated with multiple compounds from different herbs in NTF, which revealed the synergistic property of the compounds in the NTF for the treatment of ischemic stroke Durvalumab Injection (Imfinzi)- FDA CIRI. The cells of the ischemic core area experience a sudden reduction of blood flow, within just several minutes after ischemic attack with irreversible injury and subsequent cell death, and the main form of cell death is apoptosis.
