Management Trend for Unstable Pelvic Bone Fractures in Regional Trauma Centers: Multi-Institutional Study in the Republic of Korea
Purpose In the Republic of Korea, the use of trauma centers was recently adopted and is expected to have better outcome for severely injured patients. This study aimed to evaluate the clinical outcomes and treatment methods for unstable pelvic bone fractures in trauma centers. Methods The annual number of patients, clinical outcomes, and treatment methods of unstable pelvic bone fractures in three trauma centers from 2016 to 2020 were retrospectively reviewed. The patients were dichotomized into survivors and deceased, and demographic data, treatment, and clinical outcomes were compared. Multivariable analysis was performed to identify the factors associated with survival. Results Among 237 patients, 101 (42.6%) were deceased. Mortality was lower in the later period (2019–2020) compared with the early period (2016–2018; 33.6% vs. 50.0%, p = 0.011). Direct admission of an increasing number of patients to trauma centers reduced prehospital time. Although the use of angioembolization in treating pelvic bone fracture (p < 0.001), and the use of other treatment methods did not change significantly (2016–2020). Lower age, lowest systolic blood pressure in the trauma bay, and higher lactate level, international normalized ratio, the amount of packed red blood cell transfusion at 24 hours were positively associated with mortality in the multivariate analysis. Conclusion Increasingly more patients with unstable pelvic bone fracture were admitted to trauma centers; mortality improved. Angioembolization increased significantly and multi-disciplinary modality for early bleeding control was still essential
Complete chloroplast genome sequence of Rhododendron mariesii and comparative genomics of related species in the family Ericaeae
Rhododendron mariesii Hemsley et Wilson, 1907, a typical member of the family Ericaeae, possesses valuable medicinal and horticultural properties. In this research, the complete chloroplast (cp) genome of R. mariesii was sequenced and assembled, which proved to be a typical quadripartite structure with the length of 203,480 bp. In particular, the lengths of the large single copy region (LSC), small single copy region (SSC), and inverted repeat regions (IR) were 113,715 bp, 7,953 bp, and 40,918 bp, respectively. Among the 151 unique genes, 98 were protein-coding genes, 8 were tRNA genes, and 45 were rRNA genes. The structural characteristics of the R. mariesii cp genome was similar to other angiosperms. Leucine was the most representative amino acid, while cysteine was the lowest representative. Totally, 30 codons showed obvious codon usage bias, and most were A/U-ending codons. Six highly variable regions were observed, such as trnK-pafI and atpE-rpoB, which could serve as potential markers for future barcoding and phylogenetic research of R. mariesii species. Coding regions were more conserved than non-coding regions. Expansion and contraction in the IR region might be the main length variation in R. mariesii and related Ericaeae species. Maximum-likelihood (ML) phylogenetic analysis revealed that R. mariesii was relatively closed to the R. simsii Planchon, 1853 and R. pulchrum Sweet,1831. This research will supply rich genetic resource for R. mariesii and related species of the Ericaeae
The complete chloroplast genome sequence of Callitriche palustris (Plantaginaceae)
Callitriche palustris L. is an annual aquatic or marsh plant, wide spread in temperate regions throughout the world. In present study, we sequenced, assembled and annotated the complete chloroplast (cp) genome of C. palustris. The length of C. palustris complete cp genome was 150,138 bp, with a typical quadripartite structure comprising a pair of inverted repeat regions (IRs; 25,667 bp), a large single copy region (LSC; 81,432 bp) and a small single copy region (SSC; 17,372 bp). The whole cp genome contained 134 genes, including 89 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The maximum likelihood (ML) phylogenetic analysis indicated that C. palustris was a member of Plantaginaceae, but the relationships between subfamilies and tribes need more samplings. This cp genome would provide a valuable genetic resource for C. palustris’ phylogenetic study
The complete chloroplast genome sequence of China Lindera praecox (Lauraceae) and intra-species diversity
Lindera praecox is a signature composition in the broadleaved deciduous forest of East China and Japan. Presently, the complete chloroplast (cp) genome of this species was sequenced, assembled, and annotated. It is 152,818 bp in length and encodes 85 protein-coding genes, 36 transfer RNA (tRNA) genes and eight ribosomal RNA (rRNA) genes. The phylogenetic analysis indicated intraspecific varieties within L. praecox species collected in China and Japan. This chloroplast genome sequencing offers genetic background for resources conservation and phylogenetic studies
The complete chloroplast genome sequence of Sinojackia huangmeiensis (Styracaceae)
Sinojackia huangmeiensis J. W. Ge & X. H. Yao is a member of the genus Sinojackia endemic to central and east China. Here we assembled and annotated the complete chloroplast (cp) genome.

The Maximum likelihood phylogenetic analysis confirm that S. huangmeiensis is a closely related but another different species to S. sarcocarpa
Characterization of the complete chloroplast genome sequence of Limnophila sessiliflora Blume 1826 (Plantaginaceae)
Limnophila sessiliflora Blume 1826 is a perennial amphibious herb with ornamental and water purification value that is widespread in temperate and tropical Asia.
