BACKGROUND Accurate normal limits of the electrocardiogram (ECG) are the basis on which diagnostic criteria are developed. The ECG, however, is subject to age- and sex-variations and may also be racially determined. Studies into normal ECG limits for the Chinese, comprising one fifth of the world population, are few and have their limitations. We have(More)
This paper describes a novel shape-matching approach to visual target recognition for aircraft at low altitude. An artificial bee colony (ABC) algorithm with edge potential function (EPF) is proposed to accomplish the target recognition task for aircraft. EPF is adopted to provide a type of attractive pattern for a matching contour, which can be exploited(More)
Melatonin influences a number of physiological processes and is believed to play an antitumoral role in several types of cancers, but its impact on pancreatic cancer is not fully clarified. The growth inhibitory effect of melatonin on pancreatic cancer cell line SW-1990 was detected in vitro and in vivo. Annexin V/PI assay was applied to detect apoptosis(More)
This paper proposed a novel bionic selective visual attention mechanism to quickly select regions that contain salient objects to reduce calculations. Firstly, lateral inhibition filtering, inspired by the limulus' ommateum, is applied to filter low-frequency noises. After the filtering operation, we use Artificial Bee Colony (ABC) algorithm based selective(More)
Chronic pancreatitis (CP) is a common disease in the department of gastroenterology, with the main symptoms of exocrine and/or endocrine insufficiency and abdominal pain. The pathogenic mechanism of CP is still not fully clarified and the aims of treatment now are to relieve symptoms. In this study, we attempted to find a connection between interleukin-1β(More)
Ulcerative colitis (UC) is a chronic intestinal inflammatory disease. Necroptosis plays an important role in the pathogenesis of UC. Celastrol, a triterpene from the root bark of the Chinese medicinal plant Tripterygium wilfordii, has been reported to have anti-oxidant and anti-inflammatory activities in colitis. It is not known, however, how celastrol(More)
BACKGROUND Midkine (MK) is reported to be involved in the pathogenesis of numerous pathologies, but the expression of MK in acute pancreatitis (AP) has not been well studied and documented. METHODS In this study, the temporal changes of serum MK were assessed in 97 patients with AP by enzyme-linked immunosorbent assay. RESULTS The concentration of serum(More)
Hepatitis B virus (HBV) causes acute and chronic hepatitis, and is one of the major causes of cirrhosis and hepatocellular carcinoma. Accumulating evidence suggests that inflammation is the key factor for liver cirrhosis and hepatocellular carcinoma. MicroRNAs play important roles in many biological processes. Here, we aim to explore the function of(More)
OBJECTIVE To explore the effect of B7-H3 monoclonal antibody (mAb) on cerulein-induced acute pancreatitis (AP). METHODS Mice were randomly divided into three groups: control group, AP group and B7-H3 mAb treatment group. AP was induced in mice by intraperitoneal injections of cerulein. B7-H3 mAb was administered to the mice by subcutaneous injection 1(More)
