The description of schistosomiasis in China dates back more than two millennia. The disease caused social and economic hardship, and the rates of morbidity and mortality were high. In the mid 1950s, when China's population was approximately 600 million, an estimated 11.6 million people were infected with Schistosoma japonicum. Hence, a national control(More)
Bacterial DNA (bDNA) and lipopolysaccharide (LPS) are potent activators of immune cells such as monocytes and macrophages, which contribute to systemic inflammatory response syndrome (SIRS) and sepsis. Unfortunately, many experimental inflammatory antagonist-based therapies have failed in sepsis trials, and currently there is only one adjuvant therapy in(More)
To assess the impact level on physical fitness and working capacity in patients with advanced Schistosomiasis japonica, a field study was carried out. According to the records of patients with advanced schistosomiasis in Susong County, Anhui Province, 48 advanced cases without other serious chronic diseases from endemic areas in two townships and 56 healthy(More)
OBJECTIVES Occasionally, we found that artesunate enhanced the antibacterial effects of antibiotics in vitro. Therefore, the enhancement of various β-lactam antibiotics by artesunate against Escherichia coli and the possible mechanism were investigated in the present study. METHODS Antibacterial effects were observed using the serial 2-fold dilution(More)
OBJECTIVE To evaluate the effectiveness of routinely used assays for schistosomiasis diagnosis in the field. METHODS From late November to early December 2005, 6-65 years old inhabitants from 3 endemic villages were examined by Kato-Katz technique (3 thick smears) and nylon bag sedimentation/hatching method. At the same time, dipstick dye(More)
Lipopolysaccharide (LPS), the principal component of the outer membrane of Gram-negative bacteria, stimulates various cell types to release numerous proinflammatory mediators such as TNF-alpha, IL-6 and IL-12, which may damage cells and lead to organ injury, even sepsis and septic shock. Toll-like receptor 4 (TLR4) has been identified as the receptor(More)
Aptamers against inactive Vibrio alginolyticus were selected from an 82-nt ssDNA random library by systematic evolution of ligands by exponential enrichment. After 15 rounds of selection, the final pool of aptamers was highly specific for inactivated V. alginolyticus and had a dissociation constant of 27.5 ± 9.2 nM. Using these aptamers and PCR, V.(More)
Results from the third nationwide cluster sampling survey on the epidemiology of schistosomiasis in the People's Republic of China, conducted by the Ministry of Health in 2004, are presented. A stratified cluster random sampling technique was used, and 239 villages were selected in 7 provinces where Schistosoma japonicum remains endemic. A total of 250,987(More)
Two decades ago, a group of Chinese scientists discovered the antischistosomal properties of artemether, a derivative of the antimalarial drug artemisinin. However, it was only recently that the importance of this finding was recognized internationally, following a collaborative effort between Chinese, European and African scientists, who investigated the(More)
