The low diversity and large inter-individual differences of children′s intestinal microbiota are associated with antibiotic-resistant bacteria colonization and infection. Therefore, rapid and accurate detection of intestinal microbiota dysbiosisis of great significance for the prevention and treatment of intestinal infection and the rational use of antibiotics. The current intestinal pathogens detection methods have either poor accuracy or low throughput. The developing multi-omics technology can accurately detect known and unknown pathogens and can also be used to evaluate the intestinal microbiota state comprehensively. This technology will be widely applied in the detection of intestinal infections in children.

Objective To examine the health-promoting lifestyles of clinical nurses and analyze the relationship between the scores and their socio-demographic characteristics.Methods The researeh design was a cross-sectional descriptive study.The study population was 710 clinical nurses who were working at a class A tertiary teaching hospitals in a certain province.The research instruments included the healthpromoting lifestyle profile and socio-demographic characteristics of objects.Results The research findings showed that the nurses had a relatively poor health-promoting lifestyles with the mean total score at (81.41±21.71); within 52 items,the mean score of each item was (1.57:±0.42).Significant differences were found among sub-dimensions of health-promoting lifestyle profile,while nurses performed best in the interpersonal relations,subsequently followed by self realization,balanced diet,pressure management and health responsibility,but worst in exercise.There was also a statistical difference in the total score of health-promoting lifestyle among nurses who had different characteristics including marital status,education level,professional tifle,income,and taking the night shift.Conclusions The research results should raise the concern of nursing managers and clinical nurses to rectify the current status of relatively poor health- promoting lifestyles among nurses.

Objective To study on the activity of intestinal mucosal mast cells (IMMC) in dextran sulfate sodium ( DSS) induced colitis of rats. Methods Acute colitis was induced by giving 3% DSS orally. Eighteen male rats were randomized into DSS group ( n = 10 ) and normal control group ( n = 8). The rats in DSS control group drank 3% DSS solution from day 1 to day 7; those in normal control group drank water at random. Diarrhea and bloody stool as well as colonic histology were observed. The levels of colonic tissue histamine, tumor necrosis factor-a (TNF-a) and Prostaglandin E2 ( PGE2) determined with fluorimetry and ELISA, and the expression of IMMC in colonic tissue was detected by histochemical stain method. Results Compared with normal control group, the inflammatory symptoms and histologjcal damages of colonic mucosa in DSS group were significantly presented. The level of histamine in colonic tissue was significantly reduced (P

Objective Methicillin-resistant Staphylococcus aureus (MRSA) is a growing public health concern that has been associated with pediatric fatalities. This study investigated the genotypes of staphylococcal cassette chromosomal mec (SCCmec) and Panton-Valentine Leukocidin (PVL) in MRSA strains isolated from Shanghai Children's Hospital by PCR. Methods A total of 30 strains of MRSA were isolated from various clinical specimens from October 2005 to June 2006. The antimicrobial susceptibility was measured by agar diffusion method. SCCmec typing was conducted using a novel multiplex PCR assay allowing for concomitant detection of methicillin resistance (mecA gene) to facilitate detection and classification of all currently described SCCmec typesⅠ, Ⅱ, Ⅲ, Ⅳa, b, c, d andⅤ. PVL gene was also determined by PCR. Results mecA gene was positive in all the strains. SCCmecⅡ was identified in 6(20.0%) isolates, SCCmecⅢ in 15(50.0%) isolates, SCCmecⅤ in 2 and SCCmecⅣa in 1 isolate. Six MRSA strains were non-typeable. The isolates with SCCmecⅡ or SCCmecⅢ were resistant to multiple antibiotics. The strains harboring SCCmecⅣa or SCCmecⅤwere susceptible to all antibiotics except β-lactams. Eleven (36.7%) isolates were PVL positive. The genotypes and subgenotypes of staphylococcal chromosomal cassette mec of eleven PVL-positive MRSA were SCCmecⅡ(1 isolates), SCCmecⅢ (5 isolates), SCCmecⅣa (1 isolate), SCCmecⅤ (2 iso-Lates) non-typeable (2 isolates). Conclusions SCCmecⅡ and SCCmecⅢ are the major genotypes of MRSA in our hospital. These isolates are multi-resistant to antibiotics. The prevalence of PVL gene is higher in SCCmecⅡ- or SCCmeⅢ-positive MRSA. The isolates with SCCmecⅡ or SCCmecⅢ were resistant to multiple antibiotics.

0.05). The morphological changes were observed in the cochlea. Moreover, the changes of cochlear tissues under the optical microscope wasa lot of akaryotes were found in the blood capillary of cartilaginous tissue in the rats of 30 minutes after rammed; a great quantity inflammatory cells were observed in the blood capillary of cartilaginous tissue in the rats of 1 day rammed. The changes of morphology coincided with the results of DPOAE. CONCLUSION Outer hair cells may be injured by cerebral concussion and the changes were showed by DPOAE and ABR.

Objective To describe the status quo of position rotation in self-injection of insulin, and explore its influencing factors, so as to provide the basis for regulating the rotation of injection. Methods A convenient sample of 176 patients coming from endocrinology in a third grade first-class hospital were surveyed by self-designed self-injection of insulin in patients with site rotation behavior questionnaire survey. Results 176 diabetics of their own insulin injection site rotation score was 12-27 (17.79 ± 2.81) points. The age, knowledge sources, the numbers of injection sites were mainly influence to insulin injection site rotation factor score. Conclusions Diabetics insulin injection site rotation behaviors is not standard, rotation of different parts is worrying. It is necessary to strengthen the education and guidance of the site rotation of the patients.

Objective:To investigate the relationship between insight and self of schizophrenia patients by paradigm of self-reference effect(SRE).Methods:16 schizophrenia patients with insight, 16 schizophrenia patients without insight and 16 normal controls matched with age and education degree were measured by SRE, and the results were analyzed.Results:SRE was shown in normal controls, and R performance on Self task was better than on other two tasks(P0.05).This means that SRE was not demonstrated in schizophrenia patients.There were significant differences between patients without insight and normal controls in R performance(P0.05).Conclusion:The profile of the results indicates that self-disturbance is shown in schizophrenia.There is no obviously correlation between insight and self-reference effect in schizophrenia patients.
