Effect of the posterior corneal surface on total corneal astigmatism in patients with age-related cataract

International Journal of Ophthalmology(English edition) 2018年第6期11卷 958-965页

AIM： To explore the effect of the posterior astigmatism on total corneal astigmatism and evaluate the error caused by substituting the corneal astigmatism of the simulated keratometriy （simulated K） for the total corneal astigmatism in age-related cataract patients. METHODS： A total of 211 eyes with age-related cataract from 164 patients （mean age： 66.8±9.0y, range： 45-83y） were examined using a multi-colored spot reflection topographer, and the total corneal astigmatism was measured. The power vector components J0 and J45 were analyzed. Correlations between the magnitude difference of the simulated K and total cornea astigmatism （magnitude differenceSimK-Tca）, anterior J0, and absolute meridian difference （AMD） between the anterior and posterior astigmatisms were calculated. To compare the astigmatism of the simulated K and total cornea both in magnitude and axial orientation, we drew double-angle plots and calculated the vector difference between the two measures using vector analysis. A corrective regression formula was used to adjust the magnitude of the simulated K astigmatism to approach that of the total cornea. RESULTS： The magnitude differenceSimK-Tca was positively correlated with the anterior corneal J0 （Spearman’s rho= 0.539; P〈0.001） and negatively correlated with the AMDR （Spearman’s rho=-0.875, P〈0.001）. When the anterior J0 value was larger than 1.3 D or smaller than -0.8 D, the errors caused by determining the total corneal astigmatism with the karatometric calculation tended to be greater than 0.25 D. An underestimation by 16% was observed for against the rule （ATR） astigmatism and an overestimation by 9% was observed for with the rule （WTR） astigmatism when ignoring the posterior measurements. CONCLUSION： Posterior corneal astigmatism should be valued for more precise corneal astigmatism management, especially for higher ATR astigmatism of the anterior corneal surface. We suggest a 9% reduction in the magnitude of the simulated K in eyes with WT

作者： Dong-Mei Jiang ying-ying jin Liu-Hua Long Li-Jue Zhang Si-Hai Tan Pei-Pei Song Long Zhang Tai Zhang Wen-Hua Zhang Feng-Wei Wang Department of Oncology Tianjin People's Hospital Tianjin 300180 China

Objective: Radiotherapy is the main modality for treatment of malignancies, but radiation fibrosis is a severe side effect of radiotherapy which may cause severe dysfunction of patients. We design a new tr aditional Chinese her bal pr otocol, which is named as Anti-fibrosis 1, and use it in patients with severe radiation fibrosis. Methods: From Feb 2013 to Feb 2014, 23 patients with severe radiation fibrosis and apparent dysfunction were treated with anti-fib rosis 1. The re were 7 pa ti ents with nasopharyngeal car cinoma, 7 with oral cavity and oral pharyngeal carcinoma, 2 with pharyngeal carcinoma, 2 with breast carcinoma, 2 with esophageal carcinoma and 3 patients with pelvic malignancies. All patients received radiothe rapy at least 0.5-8 years ago, and 22 pa ti ents with complete response, but all patients suffered with severe radiation fibrosis. The radiation dosage was among 50-74Gy/25-37f/35-70d. Patients status of fibrosis and recovery of tissue and organ were evaluated after 0.5, 1.5 and 3 months of herbal treatment. Results: 22 of 23 patients were head and neck car cinoma, 20 pati ents had got par tial r elief afte r 15 days medication with anti-fib rosis 1, nea rly all pa ti ents had got appa rent r elief afte r 1.5 month of medication. But, there was no apparent difference between 1.5 month and 3 months group. There were no apparent side effects after the herbal treatment. Conclusions: The traditional Chinese herbal protocol anti-fibrosis 1 is an effective and safe modality for radiation fibrosis. And the apparent effect occurred after 1.5 month of herbal medication.

Broadband and perfect terahertz absorber based on multilayer metamaterial with cross-ring patterned structures

引用

Optoelectronics Letters 2025年第1期21卷 1-6页

作者： WEN jin LIU Zhanzhi WU Zhengwei PAN Yu ZHANG ying School of Science Xi'an Shiyou University Shaanxi Key Laboratory of Measurement and Control Technology for Oil and Gas Wells

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.

神经系统信息处理的理论研究和计算结果表明,视皮层可以通过稀疏编码 (sparse coding) 模式来处理自然刺激信息.神经元群体中,单个神经元在大多数时间里没有强的脉冲发放 (时间维稀疏性,lifetime sparseness),而针对某一刺激,只有少数神经元在特定的时间内发放 (空间维稀疏性,population sparseness).从神经元放电的时间和空间模式两个方面考察了视网膜神经节细胞群体对自然刺激(电影)的编码方式,并同实验室常用的伪随机棋盘格刺激下视网膜的反应模式进行比较,分析了视网膜神经节细胞反应的稀疏性指标,并深入探讨了其内在的时间和空间特点.结果提示,视觉系统在其最初阶段——视网膜——即开始采用一种高效节能的稀疏编码方式来处理自然视觉信息,单个神经元的时间维稀疏性节省了代谢能量消耗,而群体神经元中邻近神经元的动态成组协同发放,提高了信息向突触后神经元传递的有效性.
