ABSTRACT
OBJECTIVE@#Secreted modular calcium-binding proteins (SMOCs) are extracellular glycoproteins of the secreted protein, acidic, and rich in cysteine-related modular calcium-binding protein family and include two isoforms, SMOC1 and SMOC2, in humans. Functionally, SMOCs bind to calcium for various cell functions. In this review, we provided a summary of the most recent advancements in and findings of SMOC1 and SMOC2 in development, homeostasis, and disease states.@*DATA SOURCES@#All publications in the PubMed database were searched and retrieved (up to July 24, 2019) using various combinations of keywords searching, including SMOC1, SMOC2, and diseases.@*STUDY SELECTION@#All original studies and review articles of SMOCs in human diseases and embryo development written in English were retrieved and included.@*RESULTS@#SMOC1 and SMOC2 regulate embryonic development, cell homeostasis, and disease pathophysiology. They play an important role in the regulation of cell cycle progression, cell attachment to the extracellular matrix, tissue fibrosis, calcification, angiogenesis, birth defects, and cancer development.@*CONCLUSIONS@#SMOC1 and SMOC2 are critical regulators of many cell biological processes and potential therapeutic targets for the control of human cancers and birth defects.

ABSTRACT
Evidence-based medicine offers explicit methods to evaluate the evidence grades of literature. However, evidence grades do not meet all the practical needs of physicians. This study is aimed to develop a convenient method for evaluating the clinical value of medical literature from the perspective of the clinician. A literature applicability equation was formulated through the Delphi method and the analytic hierarchy process. A consistency check was used to ascertain the efficacy of the formula. Three senior clinicians assessed 30 articles based on their clinical experiences and subjective opinions, while one independent researcher performed independent assessments of the applicability of 30 articles using the evaluation formula. The literature applicability equation was Y = 3.93X[1] + 11.78X[2] + 14.83X[3] + 44.53X[4] + 24.93X[5], where Y = literature applicability, X[1] = years since publication, X[2] = target question covered or not, X[3] = sample size, X[4] = study type, and X[5] = journal quality. Consistency index [CI] values for the first-level indicator ["literature applicability"] and the second-level indicators ["pertinence and timeliness" and "quality of results"] were 0.0325, 0.0012, and 0.0001, respectively. The weights used to calculate the matrix indicators had satisfactory accordance [random coincidence coefficient = 0.056]. A consistency check for the efficacy of the formula revealed kappa = 0.749 and P < .001. The developed and validated literature applicability evaluation formula may be a useful and convenient tool for identifying clinically valuable medical literature
