In this paper, the curing process of Elium resin of various thicknesses was simulated and experimentally verified using Abaqus simulation software. This was done in order to accurately predict the exothermic behavior of Elium resin. A finite element model of Elium resin curing was developed based on the transient non-linear heat transfer equation of the resin curing model. The findings demonstrate that the simulation results for the curing temperature agree with the experimental findings, and the peak curing temperature exhibits a non-linear increasing trend as resin thickness increases. When the peak curing temperature approaches 100 ℃, resin bubbles are produced, providing a theoretical foundation for optimising the Elium composite curing process. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To probe into the effects of Xuebijing injection on myocardial injury markers and inflammatory indicators in patients with sepsis complicated with myocardial injury. METHODS: By retrospective analysis, 36 patients with sepsis complicated with myocardial injury admitted into the department of intensive care medicine in Beijing Changping District Integrated Chinese and Western Medicine Hospital from Jun. 2018 to Oct. 2021 were extract to be divided into the control group and the control group according to different treatment methods, with 18 cases in each group. The control group was treated with conventional western medicine, while the observation group received Xuebijing injection on the basis of the control group. The improvement of myocardial injury markers [troponin I(cTnI), creatine kinase isoenzyme(CK-MB)], N-terminal pro-brain natriuretic peptide(NT-proBNP) and inflammatory indicators [procalcitonin(PCT), C-reactive protein(CRP) and white blood cell count(WBC)] were compared between two groups. RESULTS: After treatment of 10 d, the improvement of indicators in the observation group was better than that in the control group. (1) The levels of myocardial injury markers (cTnI, CK-MB) and NT-proBNP in the observation group after treatment were lower than those in the control group, the differences were statistically significant ( P < 0. 05). (2) The levels of inflammatory indicators ( PCT, CRP and WBC) in the observation group after treatment were lower than those in the control group, with statistically significant differences (P<0. 05). CONCLUSIONS: Xuebijing injection is beneficial to improve the levels of myocardial injury markers and reduce the levels of inflammatory indicators in patients with sepsis complicated with myocardial injury.

BACKGROUND: As seed cells, human umbilical cord mesenchymal stem cells have many advantages, such as a broad array of sources, easy access, low immunogenicity, osteogenic differentiation potential, high proliferation and self-renewal ability. In recent years, there are more and more reports about their application for bone tissue engineering. OBJECTIVE: To summarize isolation, culture, osteogenic induction and scaffolds. METHODS: The first author searched CNKI and PubMed databases with key words of “human umbilical cord mesenchymal stem cells, isolation, culture, osteogenic differentiation, scaffold, bone tissue engineering” in both Chinese and English, so as to review the relevant literature from 2004 to 2020. Finally, 104 articles were included. RESULTS AND CONCLUSION: There are different methods of isolation and culture of umbilical cord mesenchymal stem cells. Serum-free or animal serum substitute culture system and co-culture technique have made great progress, and three-dimensional culture system will be the development direction in the future. The exact mechanisms of osteogenic differentiation of umbilical cord mesenchymal stem cells are unclear, which need further elucidation. To date, it is still the focus of researchers to develop composite scaffolds with better properties. Bio-printing technology has primarily solve the difficult problem of controlling precisely the complex inner structure of the scaffolds at the micron scale and fabricating individual scaffolds, bringing great hope for bone tissue engineering. The design and fabrication of scaffolds with multiple ideal compositions (including biocompatibility, high porosity at the micro and macro level, mechanical properties, related absorption and so on) and the less clinical side effects remain one of the key challenges in bone tissue engineering.

Through redundancy analysis, the change of the soil pH, total salt content and soluble salt ion content and the correlation between the elements of different farmland in the new agricultural land reclamation oasis in Yili River Valley were fully excavated, which provided scientific support for reasonable irrigation and agricultural sustainable development in this area.【Method】Taking the different farmland soils of the new agricultural land reclamation oasis in Yili River Valley as the research object, the method of combining traditional statistics and redundancy analysis was used.【Result】（i）Among the different farmland types, except for the slight salinization in the wheat field, the rest of farmland is moderate salinization, and the degree of alkalization is moderate. The highest mean content of soluble salt ions is SO2-4, and cationic is K++Na+.From the results of redundancy analysis, it is found that the first two coordinate axis explain more than 80 % of the soil salinization information in the area, clearly indicating the relationship between soil salinization index and soluble salt ions.（ii）From the whole perspective, the soil salinity of different farmland is relatively correlated with SO2-4. The rest of the farmland except for Medicago sativa has strong correlation with Ca2+, and the anion and cation have influence on pH and exchangeable sodium percentage.【Conclusion】It is concluded that the content of soluble salt ions in different farmland types has a certain correlation with the salinization index. Compared with traditional statistical methods, redundant analysis can directly express the main factors affecting salinization indicators, and provide a new and effective method for analyzing salinization information.

Objective To explore the protective effects of butylphthalide against Aβ25-35 induced dementia-like pathological rat model and reveal the mechanism. Methods Rats were divided into five groups: control group, model group and NBP groups (10, 30, and 100mg/kg). In model group and butylphthalide groups, Aβ25-35 was injected into the lateral ventricle, while the rats in intervention group were administered with butylphthalide (gastric infusion dose of 2.5mL/kg). Learning and memory abilities of the rats were observed with water maze test. Mitochondrial function in brain tissue was observed by ATP assay, and the mitochondrial related enzyme activities were detected by the kit. Results Water maze test showed that learning and memory abilities of model group were poorer than those of control group. They were significantly improved in NBP 10mg/kg group and 30mg/kg group (P<0.05), but did not change significantly in 100mg/kg group. Compared with control group, model group had significantly decreased ATP level (P<0.05); cytochrome c oxidase, pyruvate dehydrogenase complex and ketoglutarate dehydrogenase activities were also significantly decreased (P<0.05). Compared with model group, butylphthalide group had significantly improved activities of mitochondrial enzymes that improved mitochondrial function. Conclusion Butylphthalide can improve learning and memory abilities of rats with Aβ25-35-induced dementia by improving mitochondrial function. [ABSTRACT FROM AUTHOR]
