  • The Clinical Usage of Small Dose and Low Pressure Lavage in Gastrointestinal Hemorrhage Induced by Acute Poisoning

    ObjectiveTo explore the effects of small dose and low pressure lavage on gastrointestinal hemorrhage induced by acute poisoning. MethodsWe collected the clinical data of all the patients diagnosed as gastrointestinal hemorrhage induced by acute poisoning treated between January 2011 and December 2012. The patients were divided into two groups: control group and treatment group, according to the different treatments they underwent. The control group received traditional treatment only, while the treatment group received small dose and low pressure lavage as well as the traditional treatment. After recording the ages, poisoning dose, pretreatment time, shock and complications, we evaluated the risk of death by calculating ROCKALL scores. ResultsThe differences of ages, sexes, and poisoning dose between these two groups were not significant. However, the death rate in high and middle risk patients of the treatment group was significantly lower than that of the control group (P<0.05). ConclusionThe small dose and low pressure lavage can improve the prognosis of the gastrointestinal hemorrhage induced by acute intoxication.

  • Investigation of Self-management Status in Patients with Ankylosing Spondylitis

    ObjectiveTo understand the self management status of patients with ankylosing spondylitis (AS). MethodsSixty inpatients and outpatients with AS in the Department of Rheumatology between December 2011 and December 2012 were selected as the study subjects by judgment sampling method. A self-made questionnaire was used for investigation. ResultsThe self-management skills of 10.0% of the patients were poor, 78.3% were moderate and 11.7% were fine. The self-management skills of functional training and keeping healthy lifestyle were relatively poor. The factors with a score from the highest to the lowest were:the mental self-management, symptom management, keeping healthy lifestyle, and the self-management of functional training. ConclusionsThe self-management skills of patients with ankylosing spondylitis range from moderate to relatively poor. Our results suggest that cultural factors and the course of disease may be the main influence factors for self-management skills of patients. Clinical medical personnel should know the situation of patients sufficiently, improve the processes of health education and take corresponding intervention measures to the lack of self management ability. By the above ways, we can improve the compliance obedience and the self-management skills of patients, then the patients' condition and living quality will be greatly improved.

  • Prediction of Antigen Epitopes of Associated Protein Rv2004c Latent-infected by Mycobacterium Tuberculosis

    To screen new tuberculosis diagnostic antigens and vaccine candidates, we predicted the epitopes of Mycobacterium tuberculosis latent infection-associated protein Rv2004c by means of bioinformatics. The homology between Rv2004c protein and human protein sequences was analyzed with BLAST method. The second structures, hydrophilicity, antigenicity, flexibility and surface probability of the protein were analyzed to predict B cell epitopes and T cell epitopes by Protean software of DNAStar software package. The Th epitopes were predicted by RANKPEP and SYFPEITHI supermotif method, the CTL epitopes were predicted by means of combination analyses of SYFPEITHI supermotif method, BIMAS quantitative motif method and NetCTL prediction method. The peptide sequences with higher scores were chosen as the candidate epitopes. Blast analysis showed that Rv2004c protein had low homology with human protein. This protein had abundant secondary structures through analysis of DNAStar software, the peptide segments with high index of hydrophilicity, antigenicity, surface probability and flexibility were widely distributed and were consistent with segments having beta turn or irregular coil. Ten candidates of B cell epitopes were predicted. The Th epitopes of Rv2004c protein were located after the 200th amino acid. Of 37 Th cell epitopes predicted, there were more epitopes of HLA-DRB1*0401 and HLA-DRB1*0701 phenotypes, and the MHC restrictive types of some Th cell epitopes exist cross overlap. Of 10 CTL epitopes predicted, there were more number and higher score of HLA-A2 restricted epitopes. Therefore Mycobacterium tuberculosis Rv2004c protein is a protein antigen with T cell and B cell epitopes, and is expected to be a new target protein candidate for tuberculosis diagnosis and vaccine.
