Enhanced recovery after surgery care to reduce surgical site wound infection and postoperative complications for patients undergoing liver surgery.

This study comprehensively assessed the effect of enhanced recovery after surgery (ERAS) on wound infection and postoperative complications in patients undergoing liver surgery. The PubMed, EMBASE, MEDLINE, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang electronic databases were searched to collect published studies on the use of ERAS in liver surgery until December 2022. Literature selection was performed independently by two investigators according to the inclusion and exclusion criteria, and quality evaluation and data extraction were performed. RevMan 5.4 software was used in this study. Compared with the control group, the ERAS group showed a significantly lower incidence of postoperative wound infection (odds ratio [OR]: 0.59, 95% confidence interval [CI]: 0.41-0.84, P = .004) and overall postoperative complication rate (OR: 0.43, 95% CI: 0.33-0.57, P < .001) and significantly shorter postoperative hospital stay (mean difference: -2.30, 95% CI: -2.92 to -1.68, P < .001). Therefore, ERAS was safe and feasible when applied to liver resection, reducing the incidence of wound infection and total postoperative complications, and shortening the length of hospital stay. However, further studies are required to investigate the impact of ERAS protocols on clinical outcomes.

Transcriptomic Profiling Reveals Shared Signalling Networks Between Flower Development and Herbivory-Induced Responses in Tomato.

Most flowering plants must defend themselves against herbivores for survival and attract pollinators for reproduction. Although traits involved in plant defence and pollinator attraction are often localised in leaves and flowers, respectively, they will show a diffuse evolution if they share the same molecular machinery and regulatory networks. We performed RNA-sequencing to characterise and compare transcriptomic changes involved in herbivory-induced defences and flower development, in tomato leaves and flowers, respectively. We found that both the herbivory-induced responses and flower development involved alterations in jasmonic acid signalling, suppression of primary metabolism and reprogramming of secondary metabolism. We identified 411 genes that were involved in both processes, a number significantly higher than expected by chance. Genetic manipulation of key regulators of induced defences also led to the expression changes in the same genes in both leaves and flowers. Targeted metabolomic analysis showed that among closely related tomato species, jasmonic acid and α-tomatine are correlated in flower buds and herbivory-induced leaves. These findings suggest that herbivory-induced responses and flower development share a common molecular machinery and likely have coevolved in nature.

Analysis of the differential gene and protein expression profile of the rolled leaf mutant of transgenic rice (Oryza sativa L.).

The importance of leaf rolling in rice (Oryza sativa L.) has been widely recognized. Although several studies have investigated rice leaf rolling and identified some related genes, knowledge of the molecular mechanism underlying rice leaf rolling, especially outward leaf rolling, is limited. Therefore, in this study, differential proteomics and gene expression profiling were used to analyze rolled leaf mutant of transgenic rice in order to investigate differentially expressed genes and proteins related to rice leaf rolling. To this end, 28 differentially expressed proteins related to rolling leaf traits were isolated and identified. Digital expression profiling detected 10 genes related to rice leaf rolling. Some of the proteins and genes detected are involved in lipid metabolism, which is related to the development of bulliform cells, such as phosphoinositide phospholipase C, Mgll gene, and At4g26790 gene. The "omics"-level techniques were useful for simultaneously isolating several proteins and genes related to rice leaf rolling. In addition, the results of the analysis of differentially expressed proteins and genes were closely consistent with those from a corresponding functional analysis of cellular mechanisms; our study findings might form the basis for further research on the molecular mechanisms underlying rice leaf rolling.
