背景:与传统的缝合方式相比,采用补片修复腹壁缺陷的无张力疝修补手术能有效减少术后疼痛和疝气复发率,已经成为近年来治疗腹疝的首选方法。目的:归纳总结不同疝修复补片在应用过程中的优缺点。方法:以“腹壁缺损,疝气补片,疝气治疗”为中文检索词,以“abdominal wall defect,hernia patches,hernia treatment”为英文检索词,分别检索中国知网、谷歌学术和PubMed数据库,检索时限主要为2018年1月至2024年2月,同时采用少数经典的早期文献以概述疝修复补片的发展历程,通过阅读题目和摘要进行初步筛选,排除与疝修复材料相关性较低的文献,最终纳入90篇文献进行归纳总结。结果与结论:根据制备材料的不同可以将疝修复补片分为不可吸收人工合成补片、可吸收人工合成补片、天然高分子补片和复合补片。不可吸收补片具有较高的机械强度,有益于疝气区域的组织愈合,但体内长期存在的补片可能会引发身体的免疫反应,导致炎症和疼痛。可吸收人工合成补片与天然高分子补片具有良好的组织相容性、降解性,但机械强度不稳定。复合材料补片继承了传统不可吸收补片优良的机械性能,同时通过可吸收部分的设计降低了一些并发症发生的风险。在疝修复补片的后续研究中,科研人员应重点关注如何将新技术与复合补片结合起来,形成多功能的疝修复补片。

Selective hydrogenation of biomass-derived 5-hydroxymethylfurfural（HMF） to 2,5-dihydroxymethyltetrahydrofuran（DHMTHF） with 96% selectivity and a complete HMF conversion is obtained over palladium catalyst supported on mesoporous graphitic carbon nitride（Pd/mpg-C_3N_4） under pressured hydrogen atmosphere in aqueous media. The excellent catalytic performance of Pd/mpg-C_3N_4 is attributed to hydrogen bonding-related competitive interactions between reactant HMF and “intermediate” 2,5-dihydroxymethylfuran（DHMF） with the support mpg-C_3N_4, which leads to a deep hydrogenation of DHMF to DHMTHF.

Rutile is a common Ti-bearing accessory mineral in high pressure （HP） metamorphic rocks of the western Tianshan. Distribution of rutile in the HP rocks varies from 0.5% in the greenschist to 30% in the rutile-bearing vein. Rutile can be subdivided into three groups based on the variation of trace elements： The first group has an averaged Zr content of 18 ppm-44 ppm and Hf content of 0.8 ppm-2.4 ppm, which correspond to occurrence of rutile from vein; the second group Zr of 59 ppm-63 ppm, Hf of 3.5 ppm-3.7 ppm; and the third group Zr of 150 ppm-160 ppm and Hf of 3.9 ppm, corresponding to rutile in the matrix of blueschist and eclogite, respectively. Rutile has been retrograded to ilmenite and titanite partly or completely, reducing the value of the ore. But rutile of HP rocks in the western Tianshan usually has the lowest content of uranium （〈1 ppm U）, which might become an attractive raw material for the Ti industry. Therefore, rutile-bearing HP rocks in the western Tianshan as a mineral resource will be the focus of considerable attention.

Terephthaloyl chloride （DB）-modified silk fibroin （SF） films were immersed into 1.5 times simulated body fluid （1.5 SBF） to regulate the mineralization of hydroxyapatite （HA） crystals at about 36.5 ℃ for 24 h. UV was used to prove that the new bonds form between the DB and SF. The structure and morphology of the SF/HA were investigated by FTIR, ICP, XRD and SEM. The results showed that the apatite deposited on the matrix of SF mainly was HA. HA was self-assembled on the matrix of SF and formed three- dimensional framework when the weight ratio of DB/SF was 0.30. The content of DB affected the structure and morphology of the anatite comoosites deoosited on the SF films.
