The repair of ancient books as an important element in the protection of ancient books,has been attached great importance in China ever since.At the sairle time,the work is facing with heavy tasks,emergent time,and lack of professional personnel.Besides,due to being emphasized too much on the experience of traditional handiworks for all the time,the work is absence of modern research,theoretical conclusion,scientific standardized management,and fund supporting.All these problems need to be solved rationally.

Necroptosis, or programmed cell death, is a type of cell death with a controllable death signaling pathway and the morphological features similar to necrosis.It is mainly mediated by death receptors or pathogen pattern re-cognition receptors.Among them, tumor necrosis factor receptor 1 (TNFR1)-mediated necroptosis is the most well-studied one.Receptor-interacting protein kinase 1 (RIPK1) and receptor-interacting protein kinase 3 (RIPK3) are the 2 key kina-ses involved in the formation of complex I & II and necrosome in the process of necroptosis.Phosphoglycerate mutase 5 ( PGAM5) , a member of phosphoglycerate mutase gene family, lacks PGAM activity and possesses the phosphatase activi-ty.PGAM5 is anchored in the mitochondrial membrane and is also called mitochondrial phosphoglycerate mutase 5.It has been shown that PGAM5 involves in the formation of necrosome during necroptosis and it is able to accelerate the fission of mitochondria by dephosphorylation of dynamin-related protein 1 (DRP1), thus promoting cell necroptosis.

Objective: To analyze some influence factors during isokinetic eccentric test. Method: Twenty normal males were tested by Biodex isokinetic test and rehabilitation system. Their peak torque(PT) and peak torque to body weight (PT/BW) were analyzed under different conditions. Result: It was found that velocity and contraction mode influence the results significantly( P＜0.01). Conclusion: Many factors must be considered during isokinetic eccentric test and training.

Objective To investigate the effect of netropsin on migration and invasion ability of gastric cancer cells and its mechanisms.Methods To determine if netropsin inhibits migration and invasion of gastric cancer cells, Transwell migration and invasion assay was performed.Then Western blot was performed to detect expression of E-cadherin and vimentin in gastric cancer cells with or without presence in medium netropsin.Finally, immunofluorescence was performed to detect changes in the cellular localization of β-catenin to validate whether Wnt/β-catenin pathway was suppressed or not.Results Netropsin with the concentration of 25 μmol/L had minimal inhibition effect on cell proliferation and was able to suppress ability of migration and invasion by inhibiting EMT in gastric cancer cells(P<0.05).Meanwhile netropsin was able to down-regulate the expression of epithelial markers E-cadherin and up-regulate the expression of mesenchymal marker vimentin.Finally,immunofluorescence showed that netropsin was able to block translocation of β-catenin from cytoplasm to nuclear.Conclusions Netropsin can inhibit EMT thereby suppressing migration and invasion of gastric cancer cells.The mechanism is that netropsin can compete with HMGA2 for transcription factor binding site thereby suppressing the Wnt/β-catenin pathway.

Objective To analyze the present research situation of stroke rehabilitation nursing in China, find out the defects and shortcomings existing in the development, and lay a good foundation for the development of stroke rehabilitation nursing. Methods The documentation published in Chinese core journals was searched in Chinese National Knowledge Infrastructure (CNKI), VIP database (VIP), Wanfang database by computer retrieval. The publishing year, journal name, scientific research funds, the method of literature research, research objects and research contents were analyzed by bibliometrics. Results A total of 253 articles were included with an increasing trend. These literature distributed in 34 kinds of Chinese core journals, fund rate was relatively good, but very few national fund, the experimental research was given priority to, and the research content was wide. Conclusions In order to better promote the rehabilitation of brain stroke patients, community rehabilitation care needs to be vigorously promoted, emphasis should be paid to the importance of patients family members, at the same time, great importance should also be attached to the combination between disciplines, in order to find better, more effective and easy methods to promote the rehabilitation nursing.
