Objective
To compare the clinical effects and safety of ultrasound (US)‐guided selective cervical nerve root injection (SCNI) and computed tomography (CT)‐guided SCNI for patients with cervical radicular pain (CRP).
Methods
Forty‐two CT‐guided SCNI procedures (26 eligible patients) and forty‐two US‐guided SCNI procedures (25 eligible patients) performed to treat CRP were identified from the medical...
Properties of cement-based materials at cryogenic temperatures are quite different from those at room temperatures. The strength of mortars at cryogenic temperatures was experimentally studied and an empirical model was established. The freezing thermodynamic process of pore water and pore size distribution in mortars were characterized by differential scanning calorimeter (DSC) and thermoporometry...
With increasing reliability and long service life, space vehicle electrical system is often difficult to obtain sufficient information about the reliability model under traditional statistic method. Considering the requirement of life evaluation, this paper introduces the accelerated testing concepts and theories which are suitable for space vehicle electrical system. Taking a certain power supply...
After the subprime crisis, banks have paid intense attention to credit portfolio concentration, for risk reduction or controlling the difference between regulatory capital and economic capital. So this paper teases out three major credit portfolio concentration risk measurement models, and makes a detailed comparative and applicable analysis of them, in order to provide a theoretical reference for...
Based on the hydrology and sediment data, an artificial neural network model which has been applied maturely and widely in all kinds of artificial neural network is established to study the relationship of channel cubage under 0m isobath in North Branch with the flow and sediment discharge at Datong gauging station, and the flow split ratio of the North Branch. The structure of the network model is...
A well-validated wave model with No. 9912 typhoon is established using Delft-SWAN mode to study the effect of wind wave caused by typhoon on the navigation channel of Changjiang River Estuary. The wave factors including the wave height, wave length, wave period and wave steepness under one typhoon wind scenario---with velocity of 20m/s and direction of NNE35°, obtained from the statistical data, are...
Previous researches indicate that both Ge Gen Qin Lian Decoction and its active frictions improve insulin resistance of HepG2 cells, and the effect of active frictions is better than former. Further study shows that they improve insulin resistance through PI-3K pathway. In order to explore the mechanisms, the effect of Ge Gen Qin Lian Decoction and its active frictions on IRS-1 mRNA of insulin resistant...
