Objective. In order to verify the safety and effectiveness of tirofiban combined with statins in the perioperative period of intracranial aneurysms, this study adopts systematic review and meta-analysis, so as to comprehensively understand the situation of intracranial aneurysms in the perioperative period, and tirofiban combined with statins was finally determined as an effective treatment drug. Methods. This study used systematic retrospective analysis and selected 80 patients with intracranial aneurysms treated in our hospital from June 2021 to June 2022 as the research objects. Through conventional drugs and tirofiban combined with statins used in this study, the intracranial levels, the probability of aneurysm rupture, and postoperative complications of the two groups were observed and recorded. Results. The analysis of 80 patients with intracranial aneurysms showed that the influence of intracranial levels in the observation group was better than that in the reference group, the rupture of aneurysms in the observation group was lower than that in the reference group, and the incidence of postoperative complications in the observation group was lower than that in the reference group. Conclusion. Through simulation verification, it is concluded that tirofiban combined with statins is safe and effective in the perioperative application of intracranial aneurysms. This drug can improve vascular recanalization, reduce the incidence of cerebrovascular disease events, and reduce the incidence of rebleeding. Its therapeutic effect is worthy of wide clinical application and promotion.

MicroRNAs (miR) are a group of non-coding, small RNAs, 18-20 nucleotides in length, that are frequently involved in the development of a variety of different types of cancer, including glioma, which is a type of severe tumor in the brain. Previous studies reported that miR-124 levels were downregulated in glioma specimens; however, the potential role of miR-124 in glioma currently remains unclear. The present study performed experiments, including dual-luciferase reporter assay (DLRA), MTT assay, transwell assay and flow cytometry, with the aim of elucidating the molecular mechanism of miR-124 in glioma. The results indicated that miR-124 expression was decreased in glioma tissues, accompanied by the increased expression of extracellular matrix metalloproteinase inducer (EMMPRIN). The expression of EMMPRIN was inhibited by miR-124 transfection. The DLRA results revealed that EMMPRIN directly targets miR-124. Furthermore, upon overexpression of miR-124 in the U87 cells, cell proliferation was significantly inhibited, apoptosis was increased, and cell migration and invasion were decreased. Furthermore, tumor growth was blocked by miR-124 in mice. Based on these results, the present study concluded that miR-124 is critical for amelioration of glioma by targeting EMMPRIN, thereby acting as a tumor suppressor. Thus, miR-124/EMMPRIN constitutes a plausible basis for the treatment of glioma.
