Preparation and evaluation of a phospholipid-based injectable gel for the long term delivery of leuprolide acetaterrh

引用

Acta Pharmaceutica Sinica B 2016年第4期6卷 329-335页

作者： Danhong long Tao Gong Zhirong Zhang Rui Ding Yao Fu Key Laboratory of Drug Targeting and Drug Delivery Systems Ministry of Education West China School of PharmacySichuan University Beijing Institute for Drug Control

A phospholipid-based injectable gel was developed for the sustained delivery of leuprolide acetate(LA). The gel system was prepared using biocompatible materials(SPME), including soya phosphatidyl choline(SPC), medium chain triglyceride(MCT) and ethanol. The system displayed a sol state with low viscosity in vitro and underwent in situ gelation in vivo after subcutaneous injection. An in vitro release study was performed using a dialysis setup with different release media containing different percentages of ethanol. The stability of LA in the SPME system was investigated under different temperatures and in the presence of various antioxidants. In vivo studies in male rats were performed to elucidate the pharmacokinetic profiles and pharmacodynamic efficacy. A sustained release of LA for 28 days was observed without obvious initial burst in vivo. The pharmacodynamic study showed that once-amonth injection of LA-loaded SPME(SPME-LA) led to comparable suppression effects on the serum testosterone level as observed in LA solution except for the onset time. These findings demonstrate excellent potential for this novel SPME system as a sustained release delivery system for LA.

语文教学之友 2025年第1期44卷 25-27页

作者：陈龙锁江苏省南通市如皋初级中学

花木兰这一替父从军、保家卫国的巾帼英雄形象与中国文学作品中贤良淑德、顺从奉献的传统女性形象并不完全相同。南北朝民歌《木兰诗》中,由矛盾、铺陈和距离构成的叙事张力,为深度解读文本提供了新的视角。

自升式平台的桩靴基础需逐级预压入海床一定深度，使其承载力满足承受上部平台自重荷载及所受到的海洋环境荷载的要求。随着压入深度的增加，土体将绕过桩靴基础侧面逐渐回流至基础顶部。桩靴基础在不同压入深度处，土体的回流模式不同，导致基础的贯入阻力发生变化。考虑完全回流和不回流两种极端情况下的土体破坏模式，利用特征线法推导了桩靴基础贯入阻力系数Nc，采用有限元极限分析法验证了计算模型的合理性。与已发表的文献中的离心机试验数据和数值模拟结果进行对比研究，验证了所提的理论方法的准确性。研究表明：光滑基底底部形成两个左右对称的弹性楔体，随着桩靴基础基底剪应力的增加，弹性楔体体积逐渐减小，当基底剪应力达到土体抗剪强度时，弹性楔体消失。贯入阻力系数Nc随着桩靴基础基底剪应力的增加呈线性增加，土体不回流情况下的贯入阻力系数比完全回流情况下的贯入阻力系数低约20%。

Solitons and Waves in （2＋l）-Dimensional Dispersive long-Wave Equation

Communications in Theoretical Physics 2006年第5X期46卷 799-803页

For a higher-dimensional integrable nonlinear dynamical system, there are abundant coherent soliton excitations. With the aid of an improved projective Riccati equation approach, the paper obtains several types of exact solutions to the （2＋l）-dimenslonal dispersive long-wave equation, including multiple-soliton solutions, periodic soliton solutions, and Weierstrass function solutions. From these solutions, apart from several multisoliton excitations, we derive some novel features of wave structures by introducing some types of lower-dimensional patterns.
