ABSTRACT
Objective To investigate the clinical features,pathogenic distribution and drug susceptibility of patients with infective endocarditis (IE).Methods Clinical data of IE patients were collected,who were admitted to Capital Medical University Affiliated Beijing Anzhen Hospital from January 2012 to March 2015.Results Three hundred and three IE patients were enrolled with age of (43 ± 16)years old.Fever (85.5％)and cardiac murmur (62.4％)were the most common clinical presentations.Congenital heart diseases was the leading underlying diseases in IE patients.Non rheumatic valve diseases (13.5％) followed.Vegetations were found in 90.4％ (274/303) patients.Streptococcus which accounted for 44.2％ was the major pathogen of IE.Staphylococcus (28.9％) was the second common pathogen.Gramnegative bacteria were diversified in categories.Gram-positive cocci were consistently sensitive to vancomycin and linezolid.Conclusions Congenital heart disease is the main underlying disease related to IE.Streptococcus is still the primary pathogen.Gram-positive cocci keep good sensitivity to vancomycin and linezolid.
ABSTRACT
Objective To explore the quality of life and the related factors in adult epilepsy patients in rural areas of Gansu province. Methods The Quality of Life in the Epilepsy-31 Inventory Chinese version (QOLIE-31) were used to evaluate the quality of life in 154 epilepsy patients and 149 healthy controls. The relationship of demographic variables (gender, age, marital status, profession and education, etc.) and clinical variables (age of onset, duration, type of seizures, seizure frequency and medication, etc.) with the quality of life were analyzed in patients. Results Compared with the con?trol group, the QOLIE-31 score was significantly lower in epileptic group [(47.63±7.74) vs. (52.28±5.75), P0.05). The differences of patients' QOLIE-31 score were significantly different between differ?ent incomes, medication types of epilepsy (P<0.05). The patient's family income (β=3.115, P=0.002) and the type of medi?cation (β=3.261, P=0.027) were factors affecting their quality of life. Conclusion The quality of life in adult patients with epilepsy is lower. Economic status of family and the number of drug type significantly affects the quality of life in patients. Reasonable drug choice to treat seizure and reduce the economic burden of the family are effective measures to improve the quality of life of patients with epilepsy.
ABSTRACT
ObjectiveTo discuss the relationship between post-traumatic stress disorder(PTSD) and self psychologieal elastic for and to provide the scientific basis early for PTSD and psychological intervention.Methods 592 students were selected with the method of random cluster sampling to be investigated with children self psychological elastic scale and post-traumatic stress disorder and screening of questionnaire.ResultsThere were 45 students were PTSD screening positive group,accounting for 7.60％ of the total number,and 15 male students,accounting for 2.53％ of the total number,there were 30 female students,accounting for 5.07％ of the total number.Male and female in psychological elastic scale score were no significant differences (P＞ 0.05 ),PTSD positive group psychological screening elastic total cent and factors points were significantly lower than negative group(P＜ 0.05),PTSD total score was a significantly negative correlation( r =- 0.454,P =0.000).ConclusionPsychology resilience can be used as predictors of incidence of PTSD.
ABSTRACT
Allergic asthma is a complex and chronic inflammatory airway disease. Interleukin-17 is a pro-inflammatory cytokine which plays critical role in the pathogenesis of allergic asthma. It has been reported that beta-arrestin2 regulated the development of allergic asthma at a proximal step in the inflammatory cascade. In this study, the influence of beta-arrestin2 on Interleukin-17 production and expression of CD4+ T lymphocytes in a murine asthma model was investigated. Splenic CD4+ T lymphocytes from wild-type mice and those from a murine asthma model were purified. CD4+ T lymphocytes from a murine asthma model were transfected with siRNAs targeting the beta-arrestin2 or were pretreated with the ERK1/2 inhibitor, PD98059. After stimulation, the protein expression of beta-arrestin2 phosphorylated-ERK1/2 and IL-17 were detection by Western blot; the mRNA expression of IL-17 were detected by real-time PCR; the accumulation of IL-17 in supernatants were detected by ELISA. We found that beta-arrestin2 phosphorylated-ERK1/2 and IL-17 expression in CD4+ T lymphocytes from a murine asthma model was increased compared with those from wildtype mice[p<0.01]. Treatment of CD4+ T lymphocytes with siRNAs targeting the beta-arrestin2 down-regulated phosphorylated- ERK 1/2 and IL-17 expression [p < 0.01]. PD98059 decreased IL-17 production and expression in CD4+ T lymphocytes in a murine asthma model [p < 0.05]. We conclude that beta-arrestin2 stimulated IL-17 production and expression of CD4+ T lymphocytes in a murine asthma model. The effect was partly mediated by ERK 1/2 activation. Targeting beta-arrestin2 biological activity could be a valid therapeutic approach for the treatment of allergic asthma
