Unlike conventional imaging technologies, fluorescent imaging benefits from its safety, high-spatial resolution and real-time capability, which make it a highly adoptable imaging method for tumor detection and image-guided surgery in clinics. There are two types of fluorescent probes, including always-on type and environment-responsive type, wherein environment-responsive probes are preferred due to higher target-to-background ratios, which can improve sensitivity and specificity. The environment-responsive probes include enzyme-reactive probes, pH-sensitive probes and hypoxia responsive probes. This review summarizes recent progress in environment-responsive probes, and discusses their potentials in tumor detection and image-guided surgery.

Objective:To explore the method and effect of endovascular treatment to innominate artery stenosis or occlusion.Methods:The data of 11 patients with stenosis or occlusion of innominate artery from January 2014 to November 2019 at Xuanwu Hospital of Capital Medical University were collected. All patients received endovascular treatment. We summarized the changes of clinical symptoms, surgical methods, perioperative complications, stent patency, and analyzed the changes in systolic blood pressure and peak blood flow velocity on the involving side.Results:All 11 patients underwent endovascular treatment. The surgical technique success rate was 100%. All patients were followed up. The follow-up time was 4-69 months, with an average of (30.1±23.4)months. 2 patients used cerebral umbrella during the operation. 1 patient was performed ipsilateral carotid endarterectomy, 1 patient underwent contralateral carotid stent implantation, 1 patient was diagnosed as severe stenosis of the innominate artery and left common carotid artery, and an innominate artery stent implantation was performed at one stage, left common carotid artery stent implantation was performed after half a year. We done operation from the femoral artery puncture approach (6 patients), brachial artery puncture approach (2 patients), axillary artery and femoral artery puncture approach (1 patients), and right common carotid artery and the femoral artery puncture approach (2 patients). 3 patients had in-stent restenosis at 6, 7and 12 months after stenting, respectively. 1 patient underwent balloon dilatation, and 2 patients underwent re-stent implantation. We have not do further intervention to 1 case of in-stent occlusion occurred 14 months after the stenting, for the clinical symptoms did not improve significantly. The clinical re-intervention rate in this group was 3/11, and the primary patency rate was 7/11. The secondary patency rate was 10/11. The symptoms of 10 patients were relieved and the weakness of right upper extremity was not significantly changed in 1 patient. No puncture point complications occurred in all patients, and no cerebral infarction occurred during the perioperative period. There were statistically significant differences in systolic blood pressure, blood pressure difference and peak blood flow velocity before and after the operation ( P<0.05). Conclusions:Endovascular treatment of innominate arterial stenosis or occlusion was safe and effective, and the appropriate surgical approach and plan should be selected according to the lesion characteristics and the whole body conditions.

The composition of serum is extremely complex,which complicates the discovery of new pharmaco-dynamic biomarkers via serum proteome for disease prediction and diagnosis.Recently,nanoparticles have been reported to efficiently reduce the proportion of high-abundance proteins and enrich low-abundance proteins in serum.Here,we synthesized a silica-coated iron oxide nanoparticle and devel-oped a highly efficient and reproducible protein corona(PC)-based proteomic analysis strategy to improve the range of serum proteomic analysis.We identified 1,070 proteins with a median coefficient of variation of 12.56%using PC-based proteomic analysis,which was twice the number of proteins iden-tified by direct digestion.There were also more biological processes enriched with these proteins.We applied this strategy to identify more pharmacodynamic biomarkers on collagen-induced arthritis(CIA)rat model treated with methotrexate(MTX).The bioinformatic results indicated that 485 differentially expressed proteins(DEPs)were found in CIA rats,of which 323 DEPs recovered to near normal levels after treatment with MTX.This strategy can not only help enhance our understanding of the mechanisms of disease and drug action through serum proteomics studies,but also provide more pharmacodynamic biomarkers for disease prediction,diagnosis,and treatment.

Grey matter (GM) alterations may contribute to cognitive decline in individuals with white matter hyperintensities (WMH) but no consensus has yet emerged. Here, we investigated cortical thickness and grey matter volume in 23 WMH patients with mild cognitive impairment (WMH-MCI), 43 WMH patients without cognitive impairment, and 55 healthy controls. Both WMH groups showed GM atrophy in the bilateral thalamus, fronto-insular cortices, and several parietal-temporal regions, and the WMH-MCI group showed more extensive and severe GM atrophy. The GM atrophy in the thalamus and fronto-insular cortices was associated with cognitive decline in the WMH-MCI patients and may mediate the relationship between WMH and cognition in WMH patients. Furthermore, the main results were well replicated in an independent dataset from the Alzheimer's Disease Neuroimaging Initiative database and in other control analyses. These comprehensive results provide robust evidence of specific GM alterations underlying WMH and subsequent cognitive impairment.
