Objective To determine the features that differentiate earthquake-related crush extremity fractures from non-earthquake-related extremity fractures by using digital radiography ( DR) and multidetector row computed tomography ( MDCT). Methods Six hundred and twenty-three consecutive victims with crush extremity fractures arising from the 2008 Sichuan earthquake, including 611 undergoing DR and 12 undergoing MDCT, entered the test group, and 316 consecutive victims with non-earthquake-related extremity fractures, including 301 undergoing DR and 15 undergoing MDCT, were enrolled in the control group. Image data were reviewed retrospectively and statistically between groups focusing on the anatomic distributions, numbers and types of extremity fractures. Results Fractures involving multiple extremities were more likely in the test group than the control group (88/623 vs 27/316 victims, P < 0.05). Fractures involving multiple bones (336/623 vs 112/316 victims) and comminuted fractures (324/623 vs 78/316 victims) were seen more frequently in the test group than the control group with both occurring predominantly in the tibia and fibula (all P < 0.05). Conclusion Earthquake-related crush fractures of extremities are more likely than non-earthquake-related extremity fractures to involve multiple extremities, multiple bones and to be comminuted. The lower extremities, predominantly the tibia and fibula, are more likely to be involved. This has implications for emergency and disaster planning in earthquake-prone regions.

Objective: To investigate features of crush extremity fractures associated with massive earthquake on digital radiography (DR) and multidetector computed tomography (MDCT).Materials and Methods: Six hundred and twenty-three consecutive patients with clinically confirmed crush extremity fractures arising from the 2008 Sichuan earthquake were enrolled into our study. Six hundred and eleven patients with suggested extremity fractures underwent DR, and 12 patients with possible knee fractures underwent MDCT. Image data were retrospectively reviewed, with the focus on anatomic sites, numbers, and status of the fractures.Results: Extremity fractures occurred in lower extremities in 428 patients, upper extremities in 151, and both lower and upper extremities in 44. Lower extremity fractures were more common than upper extremity fractures (P < 0.05), and the commonly involved bones were the tibia and fibula in 141 patients, femur in 102, tibia in 52, and fibula in 40. According to the numbers of bones involved, multiple bone fractures occurred in 336 patients and included lower extremity fractures in 231, upper extremity fractures in 61, and both lower and upper fractures in 44. Multiple fractures in lower extremities were seen more often than in upper extremities (P < 0.05). As for status of the extremity fractures, comminuted fractures occurred in 324 patients and included lower extremity fractures in 248, upper extremity fractures in 51, and both lower and upper extremity fractures in 25. Comminuted fractures were more common in lower extremities than in upper extremities (P < 0.05).Conclusion: Multiple and comminuted fractures, predominantly in the lower extremities, could be considered as features of crush extremity fractures associated with the massive Sichuan earthquake.

Objectives: Erythrophleum is a genus in the Fabaceae family. The genus contains only about 10 species, and it is best known for its hardwood and medical properties worldwide. Erythrophleum fordii Oliv. is the only species of this genus distributed in China. It has superior wood and can be used in folk medicine, which leads to its overexploitation in the wild. For its effective conservation and elucidation of the distinctive genetic traits of wood formation and medical components, we present its first genome assembly. Data description: This work generated ~ 160.8 Gb raw Nanopore whole genome sequencing (WGS) long reads, ~ 126.0 Gb raw MGI WGS short reads and ~ 29.0 Gb raw RNA-seq reads using E. fordii leaf tissues. The de novo assembly contained 864,825,911 bp in the E. fordii genome, with 59 contigs and a contig N50 of 30,830,834 bp. Benchmarking Universal Single-Copy Orthologs (BUSCO) revealed 98.7% completeness of the assembly. The assembly contained 471,006,885 bp (54.4%) repetitive sequences and 28,761 genes that coded for 33,803 proteins. The protein sequences were functionally annotated against multiple databases, facilitating comparative genomic analysis. [ABSTRACT FROM AUTHOR]

Objective: To investigate the profile of pelvic crush fractures in earthquake victims on digital radiography (DR) and multidetector computed tomography (MDCT).Materials and Methods: One hundred and sixty-seven consecutive survivors of the 2008 Sichuan earthquake with pelvic crush fractures classified into types according to the Tile classification system, entered our study. One hundred and thirty-nine, and 28 patients underwent DR and MDCT scans, respectively. Data were reviewed retrospectively focusing on anatomical sites, numbers, and classification of pelvic ring fractures.Results: Pelvic fractures occurred in the pubis in 88 patients (52.7%), in other pelvic bones in 32 (19.16%), and in both the pubis and other pelvic bones in 47 (28.14%). Pubic fractures were more common than fractures of other pelvic bones, and involvement of bilateral pubis was more common than that of the left or right pubis (all p < 0.05). As for the numbers of pelvic bones involved, multiple fractures occurred in 48.52% patients (81 out of 167) composed predominantly of fractures of two bones in 58.02% (47 out of 81), and were seen more often in bilateral pubis than in any other pelvic bones (p < 0.05). Regarding classifications of pelvic ring fractures, they were Type A in 31 patients (18.56%); Type B in 72 (43.11%), predominantly Type B2 in 26 (15.58%) and Type B3 in 28 (16.77%); and Type C in 64 (38.32%), predominantly Type C3 in 40 (23.95%).Conclusion: Pelvic crush fractures particularly including multiple pelvic fractures, occurring predominantly in bilateral pubis, and composed of Type C3 followed by Type B3 and Type B2, could be considered to be the profile of pelvic crush fractures in an earthquake.
