| 1 | Peroxidase-mimicking evodiamine/indocyanine green nanoliposomes for multimodal imaging-guided theranostics for oral squamous cell carcinoma显示文摘Here,evodiamine(EVO)and the photosensitizer indocyanine green(ICG)were integrated into a liposomal nanoplatform for noninvasive diagnostic imaging and combinatorial therapy against oral squamous cell carcinoma(OSCC).EVO,as an active component extracted from traditional Chinese medicine,not only functioned as an antitumor chemotherapeutic agent but was also capable of 68Ga-chelation,thus working as a contrast agent for positron emission tomography/computed tomography(PET/CT)imaging.Moreover,EVO could exhibit peroxidase-like catalytic activity,converting endogenous tumor H2O2 into cytotoxic reactive oxygen species(ROS),enabling Chemo catalytic therapy beyond the well-known chemotherapy effect of EVO.As proven by in vitro and in vivo experiments,guided by optical imaging and PET/CT imaging,we show that the theragnostic liposomes have a significant inhibiting effect on in situ tongue tumor through photodynamic therapy combined with chemodynamic chemotherapy. | Zheng Wei Huihui Zou Gongyuan Liu Chuanhui Song Chuanchao Tang Sheng Chen Guorong Zhang Jianchuan Ran Yufeng Wang Xiteng Yin Yu Cai Wei Han | 2021 | Bioactive Materials2021，6，7： | 2 |
| 2 | The impact of posterior corneal astigmatism on the surgical planning of toric multifocal intraocular lens implantation显示文摘Purpose:To investigate the influence of posterior corneal astigmatism on the prediction accuracy of toric multifocal intraocular lens(IOL)calculation.Methods:The keratometric astigmatism measured by Lenstar LS 900(KCA_(L)),keratometric astigmatism(KCAp)and total corneal astigmatism(TCA)measured by Scheimpflug camera(Pentacam HR)were documented and analyzed accordingly.Three deduction models using different parameters were compared.Model 1:KCA_(L)+keratometric comeal surgically induced astigmatism(KCSIA,0.30 D@50°);Model 2:KCA_(P)+KCSIA);Model 3:TCA 4-total CSIA(TCSIA,0.23 D@50°).The prediction errors of each model as the difference vector between the actual and the intended residual astigmatism were compared.Results:Seventy-six eyes implanted with toric multifocal IOLs were included in this study.The vector differences of the actual KCSIA and TCSIA were statistically significant in the total sample and against-the-rule(ATR)subgroup(both P<0.05).Model 1 deduced the smallest mean values of prediction error,while that of Model 3 were smaller than that of Model 2,both in the total sample and the ATR subgroups(all P<0.05).Meanwhile,in the total sample and ATR subgroups,the centroid vector magnitudes of Model 3 were smaller than that of Model 1(0.31±0.76 D and 0.39±0.76 D).Conclusions:The calculation of toric multifocal IOL should be individualized especially in the ATR eyes for the impact of PCA on the estimation of the preoperative comeal astigmatism and the CSIA. | Shaochong Bu Yuanfeng Jiang Yichen Gao Xiaomei Bai Xiteng Chen Hong Zhang Fang Tian | 2023 | Advances in Ophthalmology Practice and Research2023，3，1： | 0 |
