Study on network pharmacology of Ginkgo biloba extract against ischaemic stroke mechanism and establishment of UPLC-MS/MS methods for simultaneous determination of 19 main active components

INTRODUCTION

Ginkgo biloba extract (GBE) is an effective substance from traditional Chinese medicine (TCM) G. biloba for treating ischaemic stroke (IS). However, its active ingredients and mechanism of action remain unclear.

OBJECTIVES

This study aimed to reveal the potential active component group and possible anti-IS mechanism of GBE.

MATERIALS AND METHODS

The network pharmacology method was used to reveal the possible anti-IS mechanism of these active ingredients in GBE. An ultra-high-performance liquid chromatography triple quadrupole electrospray tandem mass spectrometry (UPLC-MS/MS) method was established for the simultaneous detection of the active ingredients of GBE.

RESULTS

The active components of GBE anti-IS were screened by literature integration. Network pharmacology results showed that the anti-IS effect of GBE is achieved through key active components such as protocatechuic acid, bilobalide, ginkgolide A, and so on. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that the possible anti-IS mechanism of GBE is regulating the PI3K-Akt signalling pathway and other signal pathways closely related to inflammatory response and apoptosis regulation combined with AKT1, MAPK, TNF, ALB, CASP3, and other protein targets. Nineteen main constituents in seven batches of GBE were successfully analysed using the established UPLC-MS/MS method, and the results showed that the content of protocatechuic acid, gallic acid, ginkgolide A, and so forth was relatively high, which was consistent with network pharmacology results, indicating that these ingredients may be the key active anti-IS ingredients of GBE.

CONCLUSION

This study revealed the key active components and the anti-IS mechanism of GBE. It also provided a simple and sensitive method for the quality control of related preparations.

Analysis of the Clinical Effect of Implementing Health Education in the Process of Ministration Elderly Hypertensive Sufferers

The clinical effect of implementing health education in ministration elderly hypertensive sufferers is analyzed. Two hundred hypertensive sufferers admitted to our hospital from February 2020 to April 2021 are selected. The two sets of sufferers are randomly divided into the examination set and the control set using the random number table method, with 100 cases in each set. The control set is given routine ministration care, and the examination set is given routine ministration to implement health education; these indicators include: the blood pressure control compliance, Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and the Chinese version of Perceived Stress Scale (CPSS) scores; the compliance rate of health knowledge score, serum Angiotensin II (Ang II), Endothelin-1 (ET-1) and Superoxide Dismutase (SOD) standards, medication compliance, prognosis quality of life, and cumulative occurrence of MACCE are compared. The experimental results show that the application of health education in the ministration process of elderly hypertensive sufferers can effectively enhance the blood pressure of the sufferers, reduce the negative emotions and psychological pressure of the sufferers, enhance the quality of life of the sufferers, and reduce the prognosis of recurrence and the occurrence of adverse cardiovascular events.
