Lignans are a powerful weapon for plants to resist stresses and have diverse bioactive functions to protect human health. Elucidating the mechanisms of stereoselective biosynthesis and response to stresses of lignans is important for the guidance of plant improvement. Here, we identified the complete pathway to stereoselectively synthesize antiviral (-)-lariciresinol glucosides in Isatis indigotica roots, which consists of three-step sequential stereoselective enzymes DIR1/2, PLR, and UGT71B2. DIR1 was further identified as the key gene in respoJanuary 2024nse to stresses and was able to trigger stress defenses by mediating the elevation in lignan content. Mechanistically, the phytohormone-responsive ERF transcription factor LTF1 colocalized with DIR1 in the cell periphery of the vascular regions in mature roots and helped resist biotic and abiotic stresses by directly regulating the expression of DIR1. These systematic results suggest that DIR1 as the first common step of the lignan pathway cooperates with PLR and UGT71B2 to stereoselectively synthesize (-)-lariciresinol derived antiviral lignans in I. indigotica roots and is also a part of the LTF1-mediated regulatory network to resist stresses. In conclusion, the LTF1-DIR1 module is an ideal engineering target to improve plant Defenses while increasing the content of valuable lignans in plants.

Objective:To investigate the efficacy and safety of nasal continuous positive airway pressure (NCPAP) combined with inhalation of pulmonary surfactant (PS) using vibrating mesh nebulizers in the treatment of neonatal respiratory distress syndrome (RDS).Methods:A prospective study was performed on premature infants with RDS admitted to the First Affiliated Hospital of Bengbu Medical College between December 2020 and June 2021. They were randomly assigned into vibrating mesh atomization technology group and intubation-surfactant-extubation (INSURE) technology group. The two groups were treated with NCPAP combined with PS. PS in the vibrating mesh atomization technology group was inhaled into the lungs by the new vibrating mesh atomization technology, while PS in the INSURE group was injected into the lungs by endotracheal tube. The pH value, arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), mechanical ventilation via endotracheal tube (MVET) demand rate, duration of respiratory support, secondary use of PS, complications, and hospital mortality were compared between the two groups. The occurrences of adverse events in the two groups were recorded. Results:A total of 42 preterm infants were finally enrolled, including 20 cases in the vibrating mesh atomization technology group and 22 cases in the INSURE technology group. There were no significant differences in blood gas analysis and PaO 2/FiO 2 before PS administration between the two groups. One hour after PS administration, blood gas analysis and PaO 2/FiO 2 were significantly improved in both groups. Compared with the INSURE technology group, the improvement of PaO 2/FiO 2 was more obvious in the vibrating mesh atomization technology group [mmHg (1 mmHg≈0.133 kPa): 198±34 vs. 173±39, P < 0.05], but no significant difference in pH value or PaCO 2 was found between the two groups. The duration of respiratory support in the vibrating mesh atomization technology group was significantly shorter than that in the INSURE technology group (hours: 96±13 vs. 120±18, P < 0.01), but there was no statistical difference in MVET demand rate [5.0% (1/20) vs. 13.6% (3/22), P > 0.05]. The incidence of periventricular-intraventricular hemorrhage (PVH-IVH) in the vibrating mesh atomization technology group was less than that in the INSURE technology group [0% (0/20) vs. 18.2% (4/22)], but no statistical difference was found ( P > 0.05). No significant differences in the secondary use rate of PS and incidence of bronchopulmonary dysplasia (BPD) or other complications were found between the vibrating mesh atomization technology group and the INSURE technology group [5.0% (1/20) vs. 9.1% (2/22), 5.0% (1/20) vs. 4.5% (1/22), both P > 0.05]. There were no deaths or serious adverse events such as pneumothorax, pulmonary hemorrhage, periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in both groups. Conclusion:Compared with the INSURE technique, NCPAP combined with vibrating mesh atomization technology was also effective and safe in the treatment of RDS, which could significantly improve PaO 2/FiO 2 and shorten the duration of respiratory support. Thus, it was worthy of clinical popularization and application.

Objective To investigate the effect of CYP3A5 and MDR1 gene polymorphisms on blood concentration of tacrolimus and creatinine level in uremic patients during the early phase after kidney transplantation in real clinical practice. Methods 131 patients who underwent kidney transplantation for the first time with triple immunotherapy based on tacrolimus in single-center from 2013 to 2017 were enrolled for retrospective study. Tacrolimus daily dose, blood concentration, blood concentration-to-dose ratio, and serum level were compared according to the various genotypes of CYP3A5 and MDR1 polymorphisms in renal transplantation recipients, respectively. Results The dosage of tacrolimus in CYP3A5*3/*3 (GG) kidney transplantation recipients within 4 weeks after kidney transplantation was lower than those of CYP3A5*1/*1 (AA) and CYP3A5*1/*3 (AG). The serum creatinine levels of patients whose tacrolimus concentration in the range of 10-13 ng/ml were close to the normal value. Conclusion CYP3A5 gene polymorphism affects the blood concentrations of tacrolimus in renal transplant recipients. No association has been found between the blood concentrations of tacrolimus and MDR1 gene polymorphism. Tacrolimus concentration in the range of 10-13 ng/ml might contribute to restore the early kidney graft function.

The quality of Paeoniae Radix Alba and Paeoniae Radix Rubra is evaluated by root thickness, and paeoniflorin serves as a common quality indicator of them. However, the correlation between the content of bioactive compounds and the root size is still unclear. Therefore, this study characterized the distribution patterns and content of seven bioactive compounds including paeoniflorin in different tissues of Paeonia lactiflora roots, analyzed the correlation between the root size and the content of bioactive compounds based on the xylem-to-bark ratio, and further determined the index components for quality assessment. Nine samples of fresh P. lactiflora roots were collected from the genuine cultivation area. The distribution of bioactive compounds in different tissues on the cross-section of the root was firstly analyzed by desorption electrospray ionization-mass spectrometry imaging(DESI-MSI). Subsequently, the content of bioactive compounds was determined in the xylems and barks of the roots by UPLC. The compounds with the largest difference between the xylem and the bark were selected by orthogonal partial least squares discriminant analysis(OPLS-DA). The results indicated that paeoniflorin, benzoylpaeoniflorin, oxypaeoniflorin, gallic acid, and 1,2,3,4,6-pentagalloylglucose were significantly accumulated in the xylems, while albiflorin and catechin were mainly distributed in the barks. Paeoniflorin and albiflorin, with the largest differences in the xylem and the bark, had the highest content in the two tissues. The root diameter was positively correlated with paeoniflorin content and negatively correlated with albiflorin content. As isomers with different efficacies, paeoniflorin or albiflorin can be chosen as the quality marker corresponding to specific clinical application to launch quality classification evaluation of multi-functional Chinese medicines.
