Background Trabeculectomy has become a mainstream treatment in intraocular pressure （lOP） reduction for primary angle-closure glaucoma （PACG）; combined trabeculectomy and cataract surgery was reported to reduce lOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract. Methods This is a comparative case series study. Thirty-one patients （31 eyes） with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone, lOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final lOP less than 21 mmHg without lOP-lowering medication. Results After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding lOP reduction （（20.59±7.94） vs. （24.85±14.39） mmHg, P=0.614）, complete success rate （88% vs. 71%, P=0.370）, formation rate of functioning blebs （65% （11/17） vs. 93% （13/14）, P=0.094）, and complications （41% （7/17） vs. 57% （8/14）, P=0.380）. lOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group. Conclusion Phacotrabeculectomy and trabeculectomy treatments exhibit similar lOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.

A Strong, Tough, and Self-Healing Strengthening Thioctic Acid-based Elastomer for Highly Reliable Flexible Strain Sensor

引用

Chinese Journal of Polymer Science 2024年第10期42卷 1610-1618页

作者： Xin-Yu Chen Yu-Bing Fu Xue-ling Yan lan Liu School of Materials Science and Engineering Key Lab of Guangdong Province for High Property and Functional Polymer Materials South China University ofTechnology

Elastomers with high strength and toughness, excellent self-healing properties, and biocompatibility have broad application prospects in wearable electronics and other fields, but preparing it remains a challenge. In this work, we propose a highly adaptable strategy by introducing the small molecule crosslinking agent of triethanolamine (TEA) to the poly(thioctic acid)(PTA) chains and preparing the PAx Ey elastomers using a simple synthesis step. This strategy stabilizes the PTA chains by constructing multiple non-covalent cross-linked dynamic networks, endowing materials with excellent strength and toughness (tensile strength of 288 kPa, toughness of 278.2 kJ/m3), admirable self-healing properties (self-healing efficiency of 121.6%within 7 h at 70°C), and good biocompatibility. The PAx Ey elastomers can also be combined with MWNTs to become flexible strain sensors, which can be used to monitor human joint movements with high sensitivity, repeatable responses, and stability.

1926年,沈从文在《世界日报·副刊》登出一则启事,这则启事显现出他初到北京时与熊希龄交往中存在的"问题"。沈从文和熊希龄在北京期间的来往,一方面反映出此时沈从文的生活状态,另一方面也体现出他在早期的生活、写作中如何呈现与确认自我身份。将此时沈从文笔下的熊希龄和1940年代他对熊希龄的评价做一对比,恰可看出沈从文在不同历史时期如何强化了自己对"湖南人"这一身份的文化认同。
