Using information technology to extract emergency decision-making knowledge from emergency plan documents is an essential means to enhance the efficiency and capacity of emergency management. To address the problems of numerous terminologies and complex relationships faced by emergency knowledge extraction of water diversion project, a multi-feature graph convolutional network (PTM-MFGCN) based on pre-trained model is proposed. Initially, through the utilization of random masking of domain-specific terminologies during pre-training, the model's comprehension of the meaning and application of such terminologies within specific fields is enhanced, thereby augmenting the network's proficiency in extracting professional terminologies.

Methods Randomized controlled trials were systematically searched from PubMed, Science Citation Index (SCI), Chinese journal full-text database (CJFD) up to December 2014. While the experimental groups (MSCs groups) were injected MSCs intravenously, the control groups were injected Delubecco's minimum essential medium (DMEM) or phosphate buffered saline (PBS).

Rats were randomly divided into the following groups (n=8): (1) sham operation group; (2) ischemia-reperfusion (I/R) rats treated with rAAV-EGFP; (3) I/R rats treated with rAAV-TNFR:Fc group. rAAV-EGFP or rAAV-TNFR:Fc was injected intra-myocardial at four sites on the anterior and posterior walls of left ventricle immediately after the construction of I/R-induced AMI model in rats.

In the previous study, we found the time-dependent and dose-dependent effects of IGF-1 treatment on the CXCR4 expression in MSCs in vitro, but it is still not clear whether IGF-1 pretreatment of MSCs may play anti-apoptotic and anti-inflammation role in myocardial infarction. In this study, we demonstrated that IGF-1-treated MSCs' transplantation attenuate cardiac dysfunction, increase the survival of engrafted cells in the ischemic heart, decrease myocardium cells apoptosis, and inhibit protein production and gene expression of inflammation cytokines tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, and IL-6.
