Progesterone is widely used to prevent threatened miscarriage. To determine the efficacy and safety of progestogens in the treatment of threatened miscarriage. PubMed, Cochrane Library, EMBASE, CNKI, CBM, and WanFang databases were searched for randomized controlled trials (RCTs) published from the date of inception of the database to August 2020. The search terms included "abortion, threatened," "progesterone," and "progestogens." A network meta-analysis was conducted of all the RCTs on threatened abortion so far to compare the efficacy and safety of different progestogens in the treatment of threatened abortion. Odds ratios for dichotomous data with 95% confidence intervals were calculated and the data were pooled using a random-effects model. The surface under the cumulative ranking area (SUCRA) was calculated for efficacy and safety with different interventions. A total of 59 RCTs with 10 424 participants were included. Oral dydrogesterone (DYD) had the lowest risk of miscarriage (SUCRA 100.0%), followed by vaginal progesterone (SUCRA 67.9%). Oral micronized progesterone had the highest risk of miscarriage (SUCRA 15.7%). Oral DYD is effective in the treatment of threatened miscarriage. The results of the present study can help patients make informed decisions about treatment options for threatened miscarriage. Oral DYD is effective in the treatment of threatened miscarriage. The results of the present study can help patients make informed decisions about treatment options for threatened miscarriage.Learning from living organisms has emerged from a mainly curiosity-driven examination, where helpful functions of biological structures have been copied, into systematic biomimetic approaches that transfer a targeted function and its underlying principles from the biological model to a technical product. Plant biomimetics is based on functional morphology, which combines the knowledge gained from the morphology, anatomy and mechanics of plants and makes a statement about their form-structure-function relationship. Since the functional morphology of plants has become key to biomimetic applications, we present its central role in deciphering the functional principles that can be applied to engineering solutions. We consider that the future of biomimetics will include bioinspired developments that will contribute to better sustainability than that achieved by conventional products.Paeonia suffruticosa (PS) and Paeonia lactiflora (PL) belong to the only genus in the family Paeoniaceae. Comparative analysis of the spatial metabolomes of PS and PL has rarely been performed. Bersacapavir clinical trial In this work, combined with multiple matrixes and dual-polarity detection, high mass resolution matrix-assisted laser desorption/ionization MS imaging (MALDI MSI) and MALDI tandem MSI were performed on the root sections of the two Paeonia species. The spatial distributions of many metabolites including monoterpene and paeonol glycosides, tannins, flavonoids, saccharides and lipids were systematically characterized. The ambiguous tissue distribution of the two isomers paeoniflorin and albiflorin were distinguished by tandem MSI using lithium salt doped 2,5-dihydroxybenzoate matrix. In addition, the major intermediates involved in the biosynthetic pathway of gallotannins were successfully localized and visualized in the root sections. High-mass resolution MALDI full-scan MSI provides comprehensive and accurate spatial distribution of metabolites. The analytical power of the technique was further tested in the tandem MSI of two isomers. The ion images of individual metabolites provide chemical and microscopic characteristics beyond morphological identification, and the detailed spatiochemical information could not only improve our understanding of the biosynthetic pathway of hydrolyzable tannins, but also ensure the safety and effectiveness of their medicinal u
