BACKGROUND High-grade prostatic intraepithelial neoplasia (HGPIN) is the most likely precursor of prostate cancer, but the frequency and timing of epigenetic changes found in prostate carcinogenesis has not been extensively documented. METHODS Here, we performed a differential proteomic profiling study on the serum of HGPIN and prostate cancer patients.(More)
BACKGROUND The prevalence of hypertension in Chinese Mainland has increased rapidly in the recent decades. This study aimed to determine the prevalence of hypertension and sodium intake in an economically booming area in China. METHODS 9600 adults aged from 18 to 69 years old in Jiangsu Province of China were recruited using a complex, multistage sampling(More)
The research of feature corner recognition for the calibration target is a crucial area for a vision-based measurement system. For the disability of detecting the corner’s location in a vehicle test system accurately, the theoretical errors based on Harris algorithm are analyzed. Experimental results show that the method can not be used in the(More)
This text based on the scattering principle of lubricating oil to near-infrared light, fully used the computer monitor technology, designed the plan of making use of near-infrared light to monitor automobile lubricating oil, and hereby it to monitor the deteriorated condition of lubricating oil. The experiment has proved that: this kind of technology for(More)
AIM To determine whether diameters of the left gastric vein (LGV) and its originating vein are associated with endoscopic grades of esophageal varices. METHODS Ninety-eight liver cirrhotic patients with hepatitis B undergoing magnetic resonance (MR) portography, and upper gastrointestinal endoscopy for grading esophageal varices were enrolled. Diameters(More)
With large scale increases of the train speed, it is of great practical significance to develop a fatigue test stand for high-speed train's transmission system. 3-DOF (three degree-of-freedom) electro-hydraulic shaking table for high-speed train's transmission system fatigue test is designed and its three dimensional mathematical model is established in(More)
Deflexion-angle is a crucial parameter for automobile controlling stability and safety. For constructing the basement of deflexion-angle detection, the model of semi-trailer train’s suspension is built and leaf spring dependent suspension is replaced with helical spring dependent suspension in the model. Balance suspension is adopted to distribute(More)
The value of the chassis gap has an important impact on driving safety and handling stability of vehicle. Focusing on the efficiency and accuracy of the detection equipment for testing chassis gap, the controlling performance influenced by chassis gap and a novel tester model is presented. The finite element analysis is adopted to ensure the reliability of(More)
