To the Editor:Assessment of data appropriateness is a process to answer whether electronic health records(EHRs)from routine healthcare practices couldt intended study purposes,for example,available to be proceeded,with enough individual records,with relevant information able to be extracted from records,etc.[1-3]This has been increasingly underscored as a prerequisite when using EHRs(one important type of real-world data[RWD])for scientic purposes.[4-6]Although controversies remain on the denitions,types and assessment methods of the dimensions of RWD appropriateness,the latest ofcial guidelines(i.e.,from the *** and Drug Administration[FDA][4]and China National Medical Products Administration[NMPA][6])suggest that the assessment start from a preliminary stage on variable existence,and subsequently deepen into the issue of data value(such as missing value,outliers,etc.),as the preliminary assessment is the foundation of the overall RWD appropriateness.[7]Little is known about the appropriateness of EHRs in developing regions,which feature high visit volumes and a great number of ***,this study aimed to preliminarily investigate RWD appropriateness from hospitals in developing regions from the perspective of core variables’comparison.

原发性牙齿萌出障碍(PFE)是一种罕见的常染色体显性遗传性疾病,主要表现为单侧或双侧后牙区开,无明显局部阻碍因素和全身因素,主要与患者牙齿萌出机制异常有关。目前研究认为其病因与甲状旁腺激素受体1(PTH1R)基因突变有密切联系,但其背后的致病机制还有待阐明。本文就与PFE发病相关的热点基因PTH1R信号缺陷与破骨细胞功能、牙囊发育、牙槽骨形成、牙周膜形成、牙根形成的研究现状进行综述,意为PFE的病因遗传学及分子机制的研究提供参考。
