Isostructural multicomponent crystals provide a promising way for fine-tuning physicochemical properties, whereas their design remains quite challenging. The purpose of this work was to provide a new strategy for obtaining isostructural multicomponent crystals by introducing coformers with functional group positional isomerism. Five isostructural salts of an antitumor drug dimethylaminomicheliolide(DMAMCL) were reported and designed with a series of dihydroxybenzoic acid regioisomers for the first time, which were identified by power and single-crystal X-ray diffractions. Similar lattice parameters suggested these obtained salts may have the same crystal packing mode. The quantitative similarity parameters via XPac, Crystal CMP and Mercury program further proved these crystal structures are3D isostructural. Hirshfeld surface maps and 2D fingerprint plots show that the isostructural salts have similar intermolecular interactions. Compared with DMAMCL, obvious improvement was observed in the thermal stability, hygroscopicity, and solubility of these isostructural salts. Meanwhile, isostructural crystals may have different physicochemical properties, even though the shape and molecular size are similar and the packing of crystal structures is equally matched.

目的通过Nomogram列线图建立一个用于预测特发性膜性肾病患者预后的模型。方法选择2018年1月~2020年12月在承德医学院附属医院首次住院并行肾穿刺活检术确诊为特发性膜性肾病(IMN)的初诊初治患者195例,并进行24个月的随访。根据随访结束时是否出现肾终点事件,将患者分为2组,分别为肾脏终点组和未达到肾脏终点组。将纳入单因素Logistic分析中P<0.2的影响因素进行多因素Logistic回归分析,按照赤池信息准则(AIC)选取最优Logistic回归模型构建IMN患者预后不良的预测模型。结果用于预测IMN预后不良预测模型的预测因子包括:年龄、平均动脉压、肾穿刺前病程、白蛋白、血肌酐。IMN患者的受试者工作特性曲线下面积(AUROC)为0.729。校准曲线的Hosmer-Lemeshow检验的统计值为1.44(P=0.49)。决策曲线(DCA)显示IMN的预测概率值在0.17至0.44之间时本模型临床适用。结论本研究构建了用于预测IMN患者预后不良的预测模型,该预测模型的预测能力、校准能力和临床净获益良好,有助于预测IMN患者的预后。

In this work,the lamellar structural evolution and microvoids variations of βpolypropylene(β-PP)during the processing of two different stretching methods,sequential biaxial stretching and simultaneous biaxial stretching,were investigated in *** was found that different stretching methods led to significantly different lamellae deformation modes,and the microporous membranes obtained from the simultaneous biaxial stretching exhibited better mechanical *** the sequential biaxial stretching,abundant coarse fibers originated from the tight accumulation of the lamellae parallel to the longitudinal stretching direction,whereas the lamellae perpendicular to the stretching direction were easily deformed and *** coarse fibers were difficult to be separated to form micropores during the subsequent transverse stretching process,resulting in a poor micropores ***,for the simultaneous biaxial stretching,theβcrystal had the same deformation mode,that is,the lamellae distributed in different directions were all destroyed,forming abundant microvoids and little coarse fibers.
