Methods:
Data of injury cases were collected from the department of emergency of two sentinel hospitals in Fuyang District from 2015 to 2020, and the incidence of injury was standardized by the data from the China's seventh national population census in Fuyang District. The demographics, causes, severity and outcomes of injury were descriptively analyzed.

Microbiology 1992;0(02):-
The ScFv gene containing Nco I and Bam HI was amplified by PCR, and inserted into the prokaryotic expression vector pHOG21 with Nco I and Bam HI digestion. After screening, high-level expression recombinant XL1-Blue (pHOG2E3) were obtained, and the different expression levels of ScFv were detected by SDS-PAGE and EUSA. When the strain was induced by 0.5 mmol/LIPTG and 0.4mol/L sucrose in the culture medium LB at 37℃ for 6 hours, the high level production of ScFv protein was obtained. The molecular weight of the expressed ScFv is 31, 000 D. The ScFv was mainly in the form of inclusion body, but it could also be in the culture medium and soluble periplasmic content. Above all, the ScFv protein could neutralize the phospholipase C activities of alpha-toxin of Gostridium perfrigens type A.

BACKGROUND: The sucrose is an ideal material for auxiliary support and mold fil ing that is suitable for application in the medical field with three-dimensional (3D) printing. In China, there are many studies about the 3D printing with sucrose, but the accuracy and porosity of the stent are stil unclear. OBJECTIVE: To explore the technological parameters of the sucrose scaffold by 3D printing technology. METHODS: From the perspective of physical and chemical properties, the sucrose viscosity and thermal decomposition with the change of temperature were analyzed. Based on the pneumatic controlled FDM technology, the mature sucrose scaffold was obtained by researching the match of temperature and pressure, layer setting, as wel as the match of speed and pressure. Then the scaffold was demarcated with microscope, and the porosity was measured by immersion in absolute ethyl alcohol. RESULTS AND CONCLUSION: The sucrose was completely melted at 180 oC, with the biggest liquidity. When the temperature was over 195 oC, the caramel reaction occurred. As the temperature increased, the sucrose viscosity decreased. The optimal molding parameters of the sucrose scaffold with pneumatic control-based 3D printing were 170 oC-0.2 MPa-12 mm/s (temperature-pressure-printing speed). The line width and mean porosity of the wel -shaped sucrose scaffold were 700 μm and 81.893%, respectively.

Chinese Traditional and Herbal Drugs 2018;49(20):4753-4759
Objective To optimize the processing integration technology of Fraxini Cortex based on response surface methodology. Methods The single factor experiment combined with Box-Behnken design was used to optimize the integrative technology, with five major characteristic components (aesculin, aesculetin, fraxetin, fraxin, and total coumarin) as indexes, in order to detect three factors (cutting thickness, drying temperature, and drying time), and research the effect of analgesic and anti-inflammatory of processing integration Fraxini Cortex. Results Optimum integrative technology of primary processing was as follows: cutting 6 mm Fraxini Cortex, and drying for 3.25 h at 75 ℃. The processing integration Fraxini Cortex significantly decreased the times of wrinkle reaction induced by acetic acid in mice, prolonged the latent period, and obviously or partially inhibited the feet swelling degree induced by carrageenan in rats. The analgesic effect of integrated technology group was more obvious than traditional technology group (P < 0.05). Conclusion This optimized integrative technology of Fraxini Cortex is reasonable and feasible with high accuracy. It could provide the scientific basis and innovative idea to the large-scale production of decoction pieces of Chinese materia medica and have the certain value for its promotion and application.

ObjectiveTo investigate the distribution and expression of y-secretase subunit (APH-1)in the central nervous system (CNS) of APP/PS1 double transgenic Alzheimer's disease (AD) adult mouse model,and to detect the expression difference of APH-1 in developmental brain between AD model mouse and wild-type littermates in order to further clarify the relationship between APH-1 and AD. MethodsOffspring bred by APP/PS1 double transgenic AD mice were genotyped.Immunohistochemical staining was used to detect APH-1 distribution and expression in the CNS of adult APP/PS1 double transgenic AD mouse model,in the brain of AD model mouse and its wild-type littermates on postnatal day 1,7,21 and 120.Results APH-1 was widely expressed in almost all regions of the CNS,especially in the cerebral cortex,hippocampus,olfactory bulb,hypothalamus,ventral striatum,caudate putamen,raphe magnus nucleus,cerebellum,brainstem and spinal cord of the adult APP/PS1 double transgenic mice.APH-1 expression was higher in the cortex of both AD and wild type mouse on postnatal day 1 than on postnatal day 7 and 21 with increased level of APH-1 protein in adult mouse brain.APH-1 expression in the brain of AD mice was higher than in its wild type littermates at any stage(P<0.05).Conclusions Distribution of APH-1 is ubiquitous and region-dependent in the CNS.The different distribution and expression between APP/PS1 double transgenic mouse model and its wild type littermate indicate that APH-1 may be related to AD.
