OBJECTIVE To investigate the clinical distribution and antibiotics resistance of Pseudomonas aeruginosa nosocomial infection after open-heart operation.METHODS The clinical data of 393 patients with nosocomial infection from Jan 2004 to Dec 2007 were analyzed retrospectively.RESULTS There were 57 infected cases caused by P.aeruginosa,and accounted for 14.5% of all infections during period.All infected patients had serious original heart diseases,and received broad-spectrum antibiotic therapy previously.Forty-two patients developed postoperative cardiorespiratory function failure,and 28 patients needed circulatory support.Thirty-six patients prolonged mechanical ventilation time for over 1 week.Results of susceptibility test showed that ciprofloxacin,levofloxacin and piperacillin/tazobactam were the most active antibiotics,followed by tobramycin,netilmicin,gentamicin,meropenem and imipenem/cilastatin.P.aeruginosa presented high resistance to ceftazidime and cefoperazone/sulbactam.CONCLUSIONS P.aeruginosa is one of the most common pathogenic bacteria after open-heart operations in our hospital and presented multidrug resistance.Rational use of antibiotics is important to reduce drug resistant strains.

Objective To explore the effects of simvastatin in the treatment of hyperlipidemia fatty liver. Methods Animal models were set up by feeding high caloric diet. Liver index (liver weight/body weight), liver function, blood lipid, liver lipid, the content of MDA in serum and liver were assayed before and after therapy with simvastatin. Results Liver index, blood lipid, liver lipid, and the content of MDA in liver as well as in serum increased significantly ( P

Objective To study the absorption and transportation of flavonoids in Herb Epimedii by using Caco-2 monolayer model. Methods Caco-2 cell monolayer model was used to study the bi-direction transport of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ. The concentration of the five flavonoids in cell culture medium was measured by UPLC and the apparent permeability coefficients (Papp) were calculated. Results The absorptive permeability coefficients (PAB) of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ were 5.91?10-7, 3.22?10-7, 2.76?10-7, 4.23?10-7, and 1.46?10-6 cm/s, respectively. Except baohuoside Ⅰ, the other four flavonodes had lower permeabilities, and the secretive permeabilities (PBA) of all the flavonoids were larger than their absorptive permeabilities. Among them, the PBA of baohuoside Ⅰ was 9.8 times as much as the PAB. Conclusion The results suggest that the intestinal absorption of the five flavonoids is lower, which might have efflux mechanism by transporters, and the absorption of monloglycoside (e.g. baohuoside Ⅰ) is better than that of diglycoside (e.g. icariin) and triglycoside (e.g. epimedin A, epimedin B, and epimedin C).

Objective To investigate the feasibility and significance of the re-operation for patients with recurrent primary liver cancer.Methods The clinical data of 58 patients with post-operative recurrence after initial operation for primary liver cancer in our hospital from January 2003 to December 2008 were analyzed.They were divided into re-operation group and the other treatment group,and the 1-and 3-year survival rates were compared.Results The 23 cases of re-operation group were all treated by local radical resection plus hepatic arterial chemotherapy pump implantation,and postoperative chemotherapy was given via hepatic artery chemoembolization pump line.The 35 patients of the other treatment group underwent radiofrequency ablation plus transcatheter hepatic arterial chemoembolization via femoral artery.The 1-and 3-year survival rates in re-operation group was 100% and 82.6% respectively,which was significantly higher than that of the other treatment group(82.9% and 45.7% respectively).Conclusions Re-operation is the treatment of choice for patients with tumor recrrrencr after radical resection of primary liver cancer,provided that the conditions are suitable and the timing of operation is appropriate.

Objective To investigate the effect of strong ion-irradiation and active macrophage on vascular endothelial cells. Methods The vascular endothelial cells(ECV-304) were divided into 3 groups: ECV304(A), ECV-304 with radiation (B)and ECV-304 with active macrophage U937 and radiation(C). The survival rates, cell cycle and apoptosis of ECV-304 were determined 48 hours after irradiation. The concentrations of TGF-?1 and VEGF in the cultured supernatant were determined by ELISA method.The protein expression of the endothelial receptor KDR in ECV-304 cells was detected by immunofluorescence and flow-cytometry while its mRNA expression was detected by RT-PCR. Results After high dose of ion-irrdiation, the cellular proliferation activity decreased, apopototic cells increased and the cell ratio in G2/M phase increased.In addition,The secretion of VEGF and TGF-?1 was promoted with the increased KDR expression. Active macrophages could alleviate the decrease of cellular proliferation and the increase of apoptotic cells and cell ratio in G2/M phase induced by ion-irriation.Furthermore,the VEGF secretion and the KDR expression were enhanced and the secretion of TGF-?1 was inhibited by the active macrophages. Conclusions Ion irradiation could induce the decrease of cellular proloferation, the increase of apoptotic cells and the cells in G2/M phase.This might partly be related to the inhibiting roles of TGF-?1 secreted by the ECV-304 cells.Active macrophages might protect the endothelial cells from radiation injury.
