Acupuncture Combined with Periocular Injection for Treatment of Hydroxychloroquine Retinopathy with Cystoid Macular Edema:A Case Report

引用

Chinese Journal of Integrative Medicine 2025年第1期31卷 68-72页

作者： LI Tian-tian wu Yan YANG Ying-xin XUE Yu-xin MA Chao-ting Department of Ophthalmology Beijing Hospital of Traditional Chinese MedicineCapital Medical UniversityBeijing100010China

Hydroxychloroquine(HCQ)is widely used in the treatment of autoimmune disorders such as systemic lupus erythematosus(SLE)and rheumatoid arthritis,and in recent years it has also been used in diseases such as cancer,neurodegenerative diseases,metabolic diseases,and microbial infections.(1)Due to the complex pharmacokinetic characteristics of HCQ,overdose or long-term use of the drug will lead to accumulation in the tissue of organism,and severe HCQ-related retinal toxicity may occur.A cohort study in America showes that after 10 and 15 years of HCQ use,the incidence of HCQ retinopathy will be 2.5%and 8.6%,respectively.(2)The clinical manifestations of HCQ retinopathy are various,mainly photoreceptor and retinal pigment epithelium(RPE)defects,some combined with cystoid macular edema(CME),and ireversible central vision loss.

Least Square Estimation for Multiple Functional Linear Model with Autoregressive Errors

引用

Acta Mathematicae Applicatae Sinica 2025年第1期41卷 84-98页

作者： Meng WANG Ming-liang SHU Jian-jun ZHOU Si-xin wu Min CHEN School of Management University of Science and Technology of ChinaHefei 230026China Academy of Mathematics and System Science Chinese Academy of SciencesBeijing 100190China Yunnan Key Laboratory of Statistical Modeling and Data Analysis Yunnan UniversityKunming 650091China

As an extension of linear regression in functional data analysis, functional linear regression has been studied by many researchers and applied in various fields. However, in many cases, data is collected sequentially over time, for example the financial series, so it is necessary to consider the autocorrelated structure of errors in functional regression background. To this end, this paper considers a multiple functional linear model with autoregressive errors. Based on the functional principal component analysis, we apply the least square procedure to estimate the functional coefficients and autoregression coefficients. Under some regular conditions, we establish the asymptotic properties of the proposed estimators. A simulation study is conducted to investigate the finite sample performance of our estimators. A real example on China's weather data is applied to illustrate the validity of our model.

Iron is a crucial micronutrient, and its deficiency can have detrimental effects on the health of infants. Dietary polysaccharide-iron(Ⅲ) complexes(PICs) are promising for addressing iron deficiency due to their minimal adverse reactions and high iron absorption rate. This study aimed to investigate the effects of dietary Enteromorpha prolifera polysaccharide-Fe(Ⅲ) complex(EP-Fe) on newborns, using 3-day weaned piglets as the iron-deficiency model. Results showed that EP-Fe improved iron levels and promoted intestinal development in piglets. Transcriptome sequencing revealed that EP-Fe increased the survival of intestinal epithelial cells under hypoxia by upregulating the expression of genes that promote the development of the vascular system. Additionally, EP-Fe enhanced the mucosal barrier functions by inhibiting myosin light chain kinase(MLCK)/phosphorylated myosin light chain(p-MLC) signaling pathway to increase the expression of intestinal tight junction proteins. Furthermore, the 16S r RNA gene sequencing of gut microbiota showed that EP-Fe promoted the enrichment of Bacteroides_fragilis and other gut microbes that can metabolize carbohydrates. In conclusion, EP-Fe is an effective iron supplement for newborns, and it can be developed as a comprehensive nutritional supplement.

This work presents an adaptive tracking guidance method for robotic fishes. The scheme enables robots to suppress external interference and eliminate motion jitter. An adaptive integral surge line-of-sight guidance rule is designed to eliminate dynamics interference and sideslip issues. Limited-time yaw and surge speed observers are reported to fit disturbance variables in the model. The approximation values can compensate for the system's control input and improve the robots' tracking ***, this work develops a terminal sliding mode controller and third-order differential processor to determine the rotational torque and reduce the robots' run jitter. Then, Lyapunov's theory proves the uniform ultimate boundedness of the proposed method. Simulation and physical experiments confirm that the technology improves the tracking error convergence speed and stability of robotic fishes.
