Analysis and Design of Intelligent Logistics System Based on Internet of Things

Based on Internet of things, .NET software development technology and GIS technology, this paper analyzes and designs a system of intelligent distribution information with software engineering life cycle theory as the guide to solve the problem of high complexity and low efficiency of manual operation in logistics and distribution, improve the level of intelligent operation and then improve the operating efficiency. It analyzes the business requirements of the system, then designs its physical architecture, software architecture and system structure, and constructs the terminal node distribution dynamic model of transmission route, realizing the main function modules of the system and verifying the correctness and effectiveness of the system results through systematic and comprehensive tests.

Effects of Different Scraping Techniques on Body Surface Blood Perfusion Volume and Local Skin Temperature of Healthy Subjects

ObjectiveTo study the mechanism and effects of different scraping techniques on body surface blood perfusion volume and local skin temperature of healthy subjects and to provide a baseline for microcirculation and energy metabolism for the evaluation of the therapeutic effects of scraping.MethodsChanges of the local blood perfusion volume and skin temperature of healthy subjects before and after applying different scraping techniques were observed with a laser Doppler imager combined with an infrared thermographic device and the resulting data was analyzed with imaging and processing software for statistical analysis.ResultsLocal blood perfusion volume and skin temperature all increased after both reinforcing and reducing scraping techniques. The value of blood flow 60 and 90 min after the reducing technique was significantly higher than that after the reinforcing technique (P<0.01), while the skin temperature increased after both techniques but was not significantly different between the two (P>0.05)ConclusionScraping can significantly improve the local blood perfusion volume, increase skin temperature and promote local blood circulation and metabolism of tissues

Angiogenesis and Vasculogenesis at 7-Day of Reperfused Acute Myocardial Infarction

Objectives &#xd;&#xa;This study is to investigate the angiogenesis and vasculogenesis at the first week of reperfused acute myocardial infarction (AMI).&#xd;&#xa;Methods &#xd;&#xa;16 of mini-swines (20 to 30 Kg) were randomly assigned to the sham-operated group and the AMI group. The acute myocardial infarction and reperfusion model was created and the pig tail catheter was performed to monitor hemodynamics before left anterior descending coronary artery (LAD) occlusion, 90 min of LAD occlusion and 120 min of LAD reperfusion. Pathologic myocardial tissue was collected at 7-day of LAD reperfusion and further assessed by immunochemistry, dual immunochemistry, in-situ hybridization, real-time quantitative polymerase chain reaction and western blot. &#xd;&#xa;Results &#xd;&#xa;The infarcted area had higher FLK1 mRNA expression than sham-operated area and the normal area (all P&#x3c;0.05), and the infarcted and marginal areas showed higher CD146 protein expression than the sham-operated area (all P&#x3c;0.05), but the microvessel density (CD31 positive expression of microvessels/HP) was not significantly different between the infarcted area and the sham-operated area (8.92&#xb1;3.05 vs 6.43&#xb1;1.54) at 7-day of reperfused acute myocardial infarction (P&#x3e;0.05). &#xd;&#xa;Conclusions &#xd;&#xa;FLK1 and CD146 expression significantly increase in the infarcted and marginal areas, and the microvessel density is not significantly different between the infarcted area and the sham-operated area, suggesting that angiogenesis and vasculogenesis in the infarcted area appear to high frequency of increase in 7-day of reperfused myocardial infarction. &#xd;&#xa

N-(4-Butanoyl-3-hy­droxy­phen­yl)butanamide

The title compound, C14H19NO3, was prepared via the intra­molecular rearrangement of 3-(butanoyl­amino)­phenyl butano­ate in the presence of anhydrous aluminium chloride. The near coplanarity of the aromatic ring, the amide group and the carbonyl group of the butanoyl fragment [N—C—C—C = −179.65 (17) and O—C—C—C = −178.34 (17)°] results from the intra­molecular O—H⋯O and C—H⋯O hydrogen bonds. In the crystal, the mol­ecules form a one-dimensional polymeric structure via N—H⋯O inter­actions between their amide groups
