The proliferation and migration of vascular smooth muscle cells (VSMCs) are key contributors to the development of atherosclerosis and restenosis. We investigated the impact of rosuvastatin (RSV) on platelet-derived growth factor (PDGF)-BB-induced proliferation and migration of VSMCs, with a focus on the Akt/mTORautophagy signaling pathways. The cytotoxicity of RSV was assessed using MTT and annexin V staining, while the proliferation and migration capabilities of PDGF-BBinduced VSMCs were evaluated using MTT and cell migration assays. Confocal microscopy was employed to examine autophagic cell images, and protein expressions were analyzed via Western blotting. Our key findings revealed that RSV inhibited PDGF-BB-induced proliferation and migration of VSMCs, significantly reducing the expression of proliferating cell nuclear antigen and matrix metalloproteinase-2, which are crucial for these processes. RSV also enhanced autophagy in PDGF-BBstimulated cells by inducing the maturation of microtubule-associated protein light chain 3 and increasing the expression of Beclin-1, autophagy related (Atg)3, Atg5, and Atg7. The regulatory effects of RSV on PDGF-BB-induced autophagy, proliferation, and migration were associated with the suppression of the Akt/mTOR signaling pathway. These findings suggest that RSV may have potential therapeutic benefits in preventing and treating vascular diseases by targeting the Akt/mTOR pathway and inducing autophagy.

Background:
Meniscal scaffold implantation has been introduced as a treatment for meniscal injuries, but there is still no clear consensus on its clinical impact, including its chondroprotective effect. This review aimed to assess the chondroprotective effects, clinical outcomes, and survivorship of meniscal scaffold implantation compared to meniscectomy, as well as among different types of scaffolds.
Methods:
A comprehensive search strategy was performed on the databases of PubMed, Embase, Cochrane Library, and Google Scholar, encompassing articles published until June 1, 2024. Randomized controlled trials (RCT) and comparative studies published in English that reported results using collagen meniscal implant (CMI) and polyurethane meniscal scaffold for meniscal tear were included.
Results:
A total of 421 studies were initially identified across databases, and a systematic review was conducted on 8 studies involving 596 patients. Among the 5 studies that addressed the chondroprotective effect, none found that meniscal scaffolds had a higher chondroprotective effect compared to meniscectomy. In studies comparing CMI and meniscectomy, the Lysholm score results showed a mean difference (MD) range between –5.90 and –4.40. In the case of visual analog scale score, the MD ranged from –1.0 to 1.0. In studies comparing polyurethane meniscal scaffolds and CMI, the Tegner score results showed an MD range of –2.0 to 0.4.
Conclusions
There was no superiority in chondroprotective effects for both CMI and polyurethane meniscal scaffolds compared to meniscectomy. Although meniscal scaffolds may provide improvements in clinical outcomes, no clinically relevant differences were observed in comparison to meniscectomy. There are no discernible differences between the 2 types of scaffolds.

Gastric cancer is one of the most common cancers in both Korea and worldwide. Since 2004, the Korean Practice Guidelines for Gastric Cancer have been regularly updated, with the 4th edition published in 2022. The 4th edition was the result of a collaborative work by an interdisciplinary team, including experts in gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology, and guideline development methodology. The current guideline is the 5th version, an updated version of the 4th edition. In this guideline, 6 key questions (KQs) were updated or proposed after a collaborative review by the working group, and 7 statements were developed, or revised, or discussed based on a systematic review using the MEDLINE, Embase, Cochrane Library, and KoreaMed database. Over the past 2 years, there have been significant changes in systemic treatment, leading to major updates and revisions focused on this area.Additionally, minor modifications have been made in other sections, incorporating recent research findings. The level of evidence and grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation system. Key factors for recommendation included the level of evidence, benefit, harm, and clinical applicability. The working group reviewed and discussed the recommendations to reach a consensus. The structure of this guideline remains similar to the 2022 version.Earlier sections cover general considerations, such as screening, diagnosis, and staging of endoscopy, pathology, radiology, and nuclear medicine. In the latter sections, statements are provided for each KQ based on clinical evidence, with flowcharts supporting these statements through meta-analysis and references. This multidisciplinary, evidence-based gastric cancer guideline aims to support clinicians in providing optimal care for gastric cancer patients.
