Objective:To explore the value of difference value and relative value of pulmonary vascular quantitative parameters of biphasic CT in diagnosis of chronic obstructive pulmonary disease (COPD) and high-risk groups.Methods:The study was a cross-sectional study. A retrospective study of 624 patients who underwent biphasic chest CT scanning in the Second Affiliated Hospital of PLA Naval Medical University from August 2018 to December 2020. Subjects were divided into three groups according to pulmonary function test: normal group ( n=321), preserved ratio impaired spirometry (PRISm) ( n=204) and COPD group ( n=99). The pulmonary vascular quantitative parameters were obtained by the workstation, including the number of pulmonary vessels (N total), cross-sectional area less than that of 5 mm 2 (N CSA5), vessel area (VA total) of 9, 12, 15, 18, 21 mm from the pleura, total blood vessels volume (TBV) and total blood vessels volume under 5 mm 2 (BV5) at expiratory and inspiratory phase. The difference value, relative value of biphasic CT were calculated. ANOVA test or Kruskal-Wallis H test was used to compare the differences of pulmonary vascular quantitative parameters among the three groups, and LSD or Bonferroni tests were used for multiple comparisons. Results:The N total, N CSA5, VA total of the whole lung in the inspiratory phase at the level of 9, 12, 15, 18 and 21 mm from the pleura and TBV, BV5 in the normal group, PRISm group and COPD group, showed an overall trend of decreasing and then increasing, and the PRISm group was lower than those of the normal group ( P<0.05). The differences in N total, N CSA5, VA total between the COPD group and the normal group at the level of 9 and 21 mm from the pleura were not statistically significant ( P>0.05), while the N total, N CSA5, V Atotal of biphasic difference value and relative value in COPD group demonstrated a significant difference from those in normal group ( P<0.05). Conclusion:The difference value and relative value of pulmonary vascular quantitative parameters in biphasic CT are more useful than single inspiratory-phase vascular parameters to differentiate the changes in pulmonary vascular remodeling between COPD patients and the normal population, and also to complement the pulmonary vascular characteristics of the PRISm population, which can provide a basis for early warning of COPD and high-risk populations.

Synthetic biology is an emerging discipline, which aims at creating artificial lives or remolding the present organisms to generate new features. To achieve these goals, synthetic biologists need to design and synthesize new genes, pathways, modules or even whole genomes. As these enabling technologies (e.g. gene synthesis, DNA assembly and genome editing) are very important for the progress of synthetic biology, we will focus on the development of these technologies in this review.
