Iron(II) phthalocyanine Loaded and AS1411 Aptamer Targeting Nanoparticles: A Nanocomplex for Dual Modal Imaging and Photothermal Therapy of Breast Cancer.
Article in International journal of nanomedicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeA multi-functional nanoplatform with diagnostic imaging and targeted treatment functions has aroused much interest in the nanomedical research field and has been paid more attention in the field of tumor diagnosis and treatment. However, some existing nano-contrast agents have encountered difficulties in different aspects during clinical promotion, such as complicated preparation process and low specificity. Therefore, it is urgent to find a nanocomplex with good targeting effect, high biocompatibility and significant therapeutic effect for the integration of diagnosis and treatment and clinical transformation. MATERIALS AND
methodsNanoparticles (NPs) targeting breast cancer were synthesized by phacoemulsification which had liquid fluorocarbon perfluoropentane(PFP) in the core and were loaded with Iron(II) phthalocyanine (FePc) on the shell. The aptamer (APT) AS1411 was outside the shell used as a molecular probe. Basic characterization and targeting abilities of the NPs were tested, and their cytotoxicity and biological safety in vivo were evaluated through CCK-8 assay and blood bio-chemical analysis. The photoacoustic (PA) and ultrasound (US) imaging system were used to assess the effects of AS1411-PLGA@FePc@PFP (A-FP NPs) as dual modal contrast agent in vitro and in vivo. The effects of photothermal therapy (PTT) in vitro and in vivo were evaluated through MCF-7 cells and tumor-bearing nude mouse models.
resultsA-FP NPs, with good stability, great biocompatibility and low toxicity, were of 201.87 ± 1.60 nm in diameter, and have an active targeting effect on breast cancer cells and tissues. With the help of PA/US imaging, it was proved to be an excellent dual modal contrast agent for diagnosis and guidance of targeted therapy. Meanwhile, it can heat up under near-infrared (NIR) laser irradiation and has achieved obvious antitumor effect both in vitro and in vivo experiments.
conclusionAs a kind of nanomedicine, A-FP NPs can be used in the integration of diagnosis and treatment. The treatment effects and biocompatibility in vivo may provide new thoughts in the clinical transformation of nanomedicine and early diagnosis and treatment of breast cancer.
