SONG Xing,a typical representative of Pre-Qin Period,who's thought is rather complicated and lucid.He was neither a novelist,a Moism nor a Taoism.By careful analyzing,SONG Xing must be considered as a thinker who inherited,integrated and developed the thought of Taoism and Moism.He blended these two different thoughts together,forming his own system of thinking.Besides,both SONG Xing and YIN Wen did their activities in Jixia,however,their thoughts were quite different from School of Jixia.It can be said that SONG Xing was not only a forerunner but also an ally of the school which was founded by Emperor Huang and Lao-Tzu.It showed a universal salvation spirit in his thoughts,such as not considering himself and helping the others,etc.
Anthocyanins are plant pigments that contribute to the color of leaves, flowers and fruits, and that are beneficial to human health in the form of dietary antioxidants. The study of a transformable crabapple cultivar, 'India magic', which has red buds and green mature leaves, using mRNA profiling of four leaf developmental stages, allowed us to characterize molecular mechanisms regulating red color formation in early leaf development and the subsequent rapid down-regulation of anthocyanin biosynthesis. This analysis of differential gene expression during leaf development revealed that ethylene signaling-responsive genes are up-regulated during leaf pigmentation. Genes in the ethylene response factor (ERF), SPL, NAC, WRKY and MADS-box transcription factor (TF) families were identified in two weighted gene co-expression network analysis (WGCNA) modules as having a close relationship to anthocyanin accumulation. Analyses of network hub genes indicated that SPL TFs are located in central positions within anthocyanin-related modules. Furthermore, cis-motif and yeast one-hybrid assays suggested that several anthocyanin biosynthetic or regulatory genes are potential targets of SPL8 and SPL13B. Transient silencing of these two genes confirmed that they play a role in co-ordinating anthocyanin biosynthesis and crabapple leaf development. We present a high-resolution method for identifying regulatory modules associated with leaf pigmentation, which provides a platform for functional genomic studies of anthocyanin biosynthesis.
On the one hand, Qian Xuantong receives the very great influence of Kang Youwei's thought of study of Confucian classics, and has very good appraisal on Xin Xue Wei Jing Kao; on the other hand, the ways are not same they walked. Kang Youwei is the modern famous scholar that studies the study of Confucian classics; but Qian Xuantong is the hero that buries the study of Confucian classics and makes the study of Confucian classics become into the study of history. Analyzing and understanding Qian Xuantong's inheritance and surmounting to Kang Youwei's thought of study of Confucian classics has important significance to know their thoughts of study of Confucian classics and the developing trend of study of Confucian classics of modern China.
For elderly patients aged ≥75 with esophageal cancer, whether surgical treatment is safe and effective and whether it is feasible to use a relatively radical "no tube, no fasting" fast-track recovery protocol remain topics of debate. We conducted a retrospective analysis to shed light on these two questions.We retrospectively collected the data of patients who underwent McKeown minimally invasive esophagectomy (MIE) combined with early oral feeding (EOF) on postoperative day 1 between April 2015 and December 2017 at Medical Group 1, Ward 1, Department of Thoracic Surgery of our hospital. Preoperative characteristics, postoperative complications, operation time, intraoperative blood loss, duration of anastomotic leakage (day), hospital stay, and survival were evaluated.Twenty-three elderly patients with esophageal cancer underwent surgery with EOF. No significant difference was observed in intraoperative measures. The incidence of postoperative complications was 34.8% (8/23). Two patients (8.7%) were terminated early during the analysis of the feasibility of EOF. For all 23 patients, the mean hospital stay was 11.4 (5-42) days, and the median survival was 51 months.Patients aged ≥75 with resectable esophageal cancer can achieve long-term survival with active surgical treatment. Moreover, the "no tube, no fasting" fast-track recovery protocol is safe and feasible for elderly patients.
Effects of ischemic postconditioning (IPostC) and adenosine triphosphate (ATP)-mediated pharmacologic postconditioning (ATP-PPostC) on cardiac function were evaluated by speckle tracking imaging (STI)-based echocardiography.A myocardial I/R model was induced in rabbits by reversible ligation of the left ventricular branch of coronary artery. Rabbits were randomized into three groups: ischemia and reperfusion (IR) (no further intervention), IPostC, and ATP-PPostC groups. Cardiac function was evaluated by conventional and STI-based echocardiography. Myocardial necrosis, apoptosis, and myocardial mRNAs of apoptosis-related proteins (Bcl-2 and Bax) were evaluated.Speckle tracking imaging (STI)-based echocardiography revealed that IPostC and ATP-PPostC were associated with better preserved global and regional cardiac function, as indicated by significantly increased GLSrsys, GLSrd, GLSsys, SrLsys, SrLd, and SLsys in both groups (all P<.5). Subsequent pathologic studies indicate that the percentage of necrotic myocardium and permillage of apoptotic cells were significantly lower in the IPostC and ATP-PPostC groups than in the IR group (all P<.05). Moreover, both IPostC and ATP-PPostC were associated with increased Bcl-2 mRNA levels and reduced Bax mRNA levels.IPostC and ATP-PPostC may exert cardioprotective functions by better preservation of cardiac function during the I/R process and at least partly via attenuation of myocardial apoptosis.
The micronutrient iron plays a crucial role in the growth and development of plants, necessitating meticulous regulation for its absorption by plants. Prior research has demonstrated that the transcription factor MxZR3.1 restricts iron absorption in apple rootstocks; however, the precise mechanism by which MxZR3.1 contributes to the regulation of iron homoeostasis in apple rootstocks remains unexplored. Here, MxMPK3-2, a protein kinase, was discovered to interact with MxZR3.1. Y2H, bimolecular fluorescence complementation and pull down experiments were used to confirm the interaction. Phosphorylation and cell semi-degradation tests have shown that MxZR3.1 can be used as a substrate of MxMPK3-2, which leads to the MxZR3.1 protein being more stable. In addition, through tobacco transient transformation (LUC and GUS) experiments, it was confirmed that MxZR3.1 significantly inhibited the activity of the MxHA2 promoter, while MxMPK3-2 mediated phosphorylation at the Ser94 site of MxZR3.1 further inhibited the activity of the MxHA2 promoter. It is tightly controlled to absorb iron during normal growth and development of apple rootstocks due to the regulatory effect of the MxMPK3-2-MxZR3.1 module on MxHA2 transcription level. Consequently, this research has revealed the molecular basis of how the MxMPK3-2-MxZR3.1 module in apple rootstocks controls iron homoeostasis by regulating the MxHA2 promoter's activity.
