Between 1988-1991,13 stains of Flavobacterium were isolated from urine of patients in hospital.The result showed that the strains were gradually increased from year to year.The Flavobacterium was gram-negative,weakly fermentatively saprophytic bacilli,could colonized.These patients had serious underlying disease,such as trauma,diabetes mellitus,congenital heart discase etc.They were immunocompromised and easily infected.Most of the patients had been produced dysbiosis because they had used high doses of antibiotic therapy.The bacteria resistant to many antibiotics and sensitivity test of drug didn't uniformity with the clinical effect so that treatment is very difficulty.Prevention and treatment of the nosocomial infection by this bacteria is important.

Giardia lamblia is an important intestinal protozoan which can cause diarrhea in humans. The detection of Giardia infection is performed through the detection methods of pathogen，immunoassay and molecular biology. Currently，the immunodiagnostic methods have good application and development prospect because of high sensitivity and specificity，simple and convenient，and time saving. In this article，we review the main progress and application of immunodiagnostic methods for Giardia infection.

Objective:To revise the Psychological Security-insecurity Questionnaire(S-I) developed by Maslow and examine its reliability and validity.Methods:Data were collected from 1893 junior middle school students with the original S-I.Results:The revised S-I consisted of 44 items,including 10 first-order factors and 3 second-order factors.It had good test-retest reliability,homogeneity reliability and criterion validity.Conclusion:The revised S-I has satisfying reliabilities and validities,and is suitable to asses the psychological security and insecurity for Chinese junior school students.

Objective:To explore the reliability and validity of Social Skills Inventory(SSI)applied in Chinese college students.Methods:A sample of 542 college students was administered SSI.Results:The Cronbach's ? coefficient of the SSI was 0.81;The test-retest reliability coefficient was 0.75;The Spearman-Brown's split-reliability of SSI was 0.84;The correlation coefficients of the six factors with the total score were 0.305～0.802;The indexes of confirmatory factor analysis were as follows:?2/df(2.2),GFI(0.888),CFI(0.903),IFI(0.916),RMSEA(0.076).Conclusion:SSI showed pretty good validity and reliability applied to Chinese college students.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
