Starting from the hydroxylamine (dimethyl amino ethanol, triethanolamine) and 1, 3-propane sultone, a series of hydroxyl and sulfonyl dual-functionalized zwitterionic salts were synthesized. Then dual-functionalized ionic liquids containing both hydroxyl and sulfonyl functional groups were produced successfully by zwitterionic salts and three kinds of strong acids (p-toluene sulfonic acid, trifluoromethanesulfonic acid, methanesulfonic acid) respectively. The structure of zwitterionic salts and dual-functional ionic liquids were confirmed by the 1H NMR and IR.

It has been well documented that the fibular collateral ligament is the primary varus stabilizer of the knee.8,10 Consequently, isolated FCL injuries can elicit abnormal varus knee instability that can lead to functional limitations, a varus thrust gait pattern, and the potential development of medial meniscal tears or medial compartment arthritis over time due to the increased compressive forces at the medial tibiofemoral compartment.16,23,30 In addition, it has been demonstrated that varus instability, primarily due to a deficient FCL from an untreated posterolateral knee injury, causes a significant increase in force on both anterior cruciate and posterior cruciate ligament reconstruction grafts.11,21,22 Therefore, a reconstruction technique to address nonrepairable acute or chronic isolated FCL tears is important to address these pathologic abnormalities.

已经证实腓侧副韧带是防止膝关节翻的主要稳定结构[8,10]。因此,FCL离断伤可以引起异常的膝关节翻不稳定,从而导致功能受限、膝摆步态和潜在发展为侧半月板撕裂或由于在增加胫股关节间隙的压力会随时间推移发生侧间室关节炎[16, 23, 30]。此外,已经证实了主要由膝关节后外侧损伤后未经治疗导致FCL功能缺陷引起的膝翻不稳可以引起前交叉韧带和后交叉韧带重建移植物受力明显[11,21,22]。因此,认为不可修复的急性或慢性FCL离断撕裂伤的重建技术对这些病理异常非常重要。

The content of Z+ZR rose obviously and descended rapidly before and when gall started on swelling, respectively. The content of IAA in leaves was descending from anaphase to telophase of gall's swelling. The content of ABA in leaves was raised just before gall's swelling and that in sheathes was raised in anaphase of the gall' swelling, but there's no visible change in culm. There was no obvious change of GA 3 content in all parts and during growth and development.
