BACKGROUND Our previous studies suggested that deoxyschizandrin (DSD) and schisantherin A (STA) may have cardioprotective effects, but information in this regard is lacking. Therefore, we explored the protective role of DSD and STA in myocardial ischemia-reperfusion (I/R) injury. METHODOLOGY/PRINCIPAL FINDINGS Anesthetized male rats were treated once with(More)
The present study explored the effect of ghrelin in protecting neurons from apoptosis in sepsis-associated encephalopathy. Ghrelin (100 nM) increased the cell viability treated with lipopolysaccharide (1.0 μg/ml, 24 h). The expression of p-Akt and Bcl-2 were decreased and caspase-3 increased both in lipopolysaccharide-treated primary hippocampal cultures(More)
Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a recently identified oncoprotein that is overexpressed in many human malignant tumors including cervical cancer. Human papillomavirus (HPV) oncoprotein E7 is the key transformation factor in cervical cancer. Our previous data showed a positive association of CIP2A and HPV-16E7 protein levels;(More)
OBJECTIVES To compare stress levels among residents in large Chinese cities between 2001 and 2008. METHODS Survey data were collected in three mainland Chinese capital cities in two waves, in 2001 and 2008, respectively. Participants were recruited through a multi-stage stratified sampling process. Stress was assessed using the Perceived Stress Scale,(More)
BACKGROUND It is reported that the infant mortality (IM) rate decreased rapidly in China and the life expectancy (LE) also had a high increase. Our objective was to determine the health status of the Chinese population by investigating IM and LE and their inter-relationship. MATERIAL AND METHODS Based on a literature review on the history and current(More)
Structural health monitoring has been studied by a number of researchers as well as various industries to keep up with the increasing demand for preventive maintenance routines. This work presents a novel method for reconstruct prompt, informed strain/stress responses at the hot spots of the structures based on strain measurements at remote locations. The(More)
BACKGROUND In China, children from low-income families, particularly those of rural to urban migrant families, have become one of the most vulnerable populations in terms of healthcare access. Without support, these families will finally give up treatment for their children. Our hospital has sought several ways to fund the uncompensated care for children(More)
The high-risk human papillomavirus (HPV) is the causative agent for cervical cancer. The HPV E7 oncogene promotes S-phase entry from quiescent state in the presence of elevated cell cycle inhibitor p27Kip1, a function that may contribute to carcinogenesis. However, the mechanism by which HPV E7 induces quiescent cells to entry into S-phase is not fully(More)
BACKGROUND China is now under a period of social transition, and inequity is evident in the field of health care. We aimed to investigate regional health-care inequalities in children's survival in Zhejiang Province, China. METHODS In our study, monitoring data of Zhejiang Province from 2005 to 2014 was collected. The flow of data collection of(More)
This paper presents a novel framework for probabilistic crack size quantification using fiber Bragg grating (FBG) sensors. The key idea is to use a high-order extended finite element method (XFEM) together with a transfer (T)-matrix method to analyze the reflection intensity spectra of FBG sensors, for various crack sizes. Compared with the standard FEM,(More)
