ABSTRACT
Background: Early identification and diagnosis of sepsis are very important because timely and appropriate treatment can improve the survival outcomes. Aim: The aim of this study was to explore the clinical signi?cance of serum cystatin C level in sepsis. Materials and Methods: The levels of serum cystatin C, C-reactive protein (CRP), and procalcitonin (PCT) were measured via enzyme-linked immunosorbent assay (ELISA). The patients with sepsis were followed up for 30 days to record their survival conditions. Results: The expression level of cystatin C was remarkably elevated in patients with sepsis compared with that in healthy controls. The serum cystatin C level was significantly correlated with the SOFA score and CRP, PCT, and creatinine levels in patients with sepsis. The patients in death group had a markedly higher level of serum cystatin C than those in survival group. The area under curve (AUC) of cystatin C for assessing the 30-day mortality rate of sepsis patients was 0.765. Conclusion: The serum cystatin C level is elevated in patients with sepsis and it may serve as a biomarker for early diagnosis of sepsis and possess promising effects in assessing the severity of sepsis and the prognosis of patients.
ABSTRACT
The present paper deals with studies on the characteristics of Schistosoma japonicum isolated from five localities in the mainland of China. The following items were observed and compared including morphometric data, susceptibility of six mammalian hosts, prepatent period, compatibility between larvae and snail hosts, size of hepatic granuloma produced by eggs, immunoreactions in experimental animals, sensitivity to praziquantel, SDS-PAGE protein pattern and its antigenicity analysis, DNA hybridization and genetic variation and differentiation by analysis with multilocus enzyme electrophoresis. By means of these multidisciplinary methods, from morphological to molecular level, the following conclusions may be drawn from our results. The evidence indicates firstly that S. japonicum in the mainland of China comprises a strain complex with several components of geographically distributed strains. At least four distinct strains exist, ie Yunnan, Guangxi, Sichuan and Anhui-Hubei. Characteristics of each strain are distinct and the results of these studies lead to discussion on the problem of the intraspecific and interstrain differentiation of S. japonicum in the mainland of China.
