Results Membrane protein OprD was analyzed in 7 clinical isolates of imipenem-intermediate P. aeruginosa. Two strains were devoid of OprD proteins and the corresponding oprD genes were found disrupted by the insertion element ISRP10 in the coding regions. Five strains had OprD proteins with different sizes. Sequence analysis showed that the peptides ranged from 427 to 443 amino acids. Multiple amino acid substitutions and / or deletions were found within the Loop 1 through Loop 8 of the OprD secondary structures. Conclusions ISRP10 inactivation and amino acid substitutions in oprD gene confer imipenem resistance in the clinical isolates of P. aeruginosa.

BACKGROUND: Dehydroepiandrosterone (DHEA) derived from adrenal cortex has an indirect bioeffect through differentiating into androgen or estrogen in the related peripheral tissues. OBJECTIVE: To verify the effects and mechanisms of DHEA on promoting osteoblasts (OBs) proliferation. DESIGN, TIME AND SETTING: The grouping controlled experiment was accomplished in Shanghai Sixth People's Hospital affiliated to Shanghai Jiao Tong University and Institute of Radiation Medicine, Fudan University from January 2006 to February 2007. MATERIALS: Ten SD rats were recruited, 1 day old, regardless of gender. DHEA was the product of American Sigma Company. METHODS: Rat OBs were separated and cultured in vitro. First generation of OBs cultured in a varied concentrations of DHEA (1?10-5, 1?10-7 and 1?10-9 mmol/L) for 72 hours were set up as the experiment group, while those exposed to 1?10-8 mmol/L of estradiol culture were regarded as positive controls and blank control group was set up as well. MAIN OUTCOME MEASURES: The OBs were identified by cell morphology and alkaline phosphatase (ALP) dyeing. Light microscope and methyl thiazolyl tetrazolium assay were used to detect the growth and proliferation of OBs. The formation of mineralized nodus was examined by alizarin bordeaux stain. The concentrations of osteoprotegerin in DHEA culture solution were also measured by double antibody sandwich ABC-ELISA simultaneously. RESULTS: ①Identification of primarily cultured OBs showed ALP dyeing was positive.②Proliferation rate of OBs was increased in experiment groups compared with that of the blank control group, and the most significant increase occurred in the concentration of 1?10-7 mmol/L DHEA culture (P 0.05).③ALP activity in experiment groups was higher, especially in the group with the concentration of 1?10-7 mmol/L DHEA (P 0.05).④ALP activity of unitary cell population was higher in 1?10-9 mmol/L DHEA culture group than that in blank control group (P

Objective To observe the effect of evidence-based nursing on improvement of preoperative fears and perioperative quality of life in patients undergoing general surgery. Methods 160 cases of general surgery patients in our hospital from September 2009 to September 2010 were chosen as the research object.The 160 cases were divided into the control group and the observation group with 80 cases in each group.The control group was taken with perioperative routine care.The observation group was given evidence-based nursing.The preoperative fear score (FAVS),perioperative quality of life (QOL)score and treatment compliance for the two groups were compared. Results The fear scores for the two groups of patients before treatment were compared.The score in the observation group was significantly lower than the control group,the difference was significant.The scores of preoperative and postnperative quality of life for the two groups were compared.The patients of the observation group were significantly higher than the patients of the control group,the difference between the two groups was significant.The treatment compliance of the observation group was better than that of the control group. Conclusions The evidence- based nursing model can improve preoperative fears and perioperative quality of Wife of patients undergoing general surgery,improve patients' treatment compliance,and promote the success of operation and recovery of patients.It is worthy of clinical application.
