Photodynamic therapy(PDT) is a promising cancer treatment that uses photosensitizers(PSs) to generate cytotoxic reactive oxygen species(ROS) under light, but improving its efficacy is crucial for clinical applications. To address this, we propose a smart nanoplatform(P@BAO-DOX) for synergistic chemo-photodynamic therapy, featuring efficient PDT, controllable drug release, and fluorescence imaging guidance. we designed an aggregation-induced emission(AIE)-based PS(BAO) with effective ROS generation and NIR-II fluorescence. Additionally, BAO as a PS and doxorubicin(DOX) as a chemo drug were encapsulated in pH-responsive nanogels(PNA) to obtain P@BAO-DOX nanogels. Upon uptake by tumor cells, the nanogel releases drugs in acidic conditions, leading to cell death. white light irradiation further triggers BAO to produce substantial ROS,enhancing phototoxicity and synergistic chemo-PDT cancer therapy. Thus, P@BAO-DOX nanogels, as a smart nanoplatform,offer precise drug release and efficient ROS generation for imaging-guided chemo-PDT synergistic therapy, showing promise in advancing cancer treatment.

Prospective case series on trabecular-iris angle status after an acute episode of phacomorphic angle closure

引用

International Journal of Ophthalmology(English edition) 2013年第1期6卷 67-70页

作者： jacky Lee Jimmy Lai Doris yick Can yuen Department of Ophthalmology University of Hong Kong Department of Ophthalmology Caritas Medical Centre

AIM:To investigate the trabecular-iris angle with ultrasound biomicroscopy (UBM) post cataract extraction after an acute attack of phacomorphic angle closure. ·METHODS:This prospective study involved 10 cases of phacomorphic angle closure that underwent cataract extraction and intraocular lens insertion after intraocular pressure (IOP) lowering. Apart from visual acuity and IOP, the trabecular-iris angle was measured by gonioscopy and UBM at 3 months post attack. ·RESULTS:In 10 consecutive cases of acute phaco-morphic angle closure from December 2009 to December 2010, gonioscopic findings showed peripheral anterior synechiae (PAS) ≤90° in 30% of phacomorphic patients and a mean Shaffer grading of (3.1±1.0). UBM showed a mean angle of (37.1°±4.5°) in the phacomorphic eye with the temporal quadrant being the most opened and (37.1°±8.0°) in the contralateral uninvolved eye. The mean time from consultation to cataract extraction was (1.4 ± 0.7) days and the mean total duration of phacomorphic angle closure was (3.6 ±2.8) days but there was no correlation to the degree of angle closure on UBM (Spearman correlation P =0.7). The presenting mean IOP was (50.5±7.4) mmHg and the mean IOP at 3 months was (10.5±3.4) mmHg but there were no correlations with the degree of angle closure (Spearman correlations P =0.9). CONCLUSION:Anopentrabecular-irisangleandnormal IOP can be achieved after an acute attack of pha-comorphic angle closure if cataract extraction is performed within 1 day-2 days after IOP control. Gonioscopic findings were in agreement with UBM,which provided a more specific and object angle measurement. The superior angle is relatively more narrowed compared to the other quadrants. All contralateral eyes in this series had open angles.

重氮树脂-聚(4-羧酸苯基)乙炔自组装膜与光电转换

A novel multiplayer film was assembled from poly[(4 carboxyphenyl)acetylene](PCPA) and diazoresin(DR) in aqueous solution via electrostatic attraction. Under UV irradiation, following the decomposition of diazonium group between the adjacent interfaces of the multiplayers, the ionic bonds of the self assembly film convert to covalent bonds and the film becomes very stable toward electrolyte solutions. Thus the photoelectric conversion property of poly[(4 carboxyphenyl)acetylene] containing film can be measured in conventional three electrode photoelectrochemical cell, and 0.5 mol/L KCl solution can be used as the supporting electrolyte. The photocurrent spectroscopy responses coincide with the absorption spectrum of the irradiated self assembly film, which indicates that the irradiated DR/PCPA film is responsible for the photocurrent generation.
