OBJECTIVE:The aim of this study was to assess the irrational use of vancomycin to treat infections of the patients with severe renal dysfunction.METHODS:Combining the results of blood concentration monitoring for vancomycin and the clinical symptoms with Micromedex Kinetidex,we evaluated whether the vancomycin was administered rationally when the infected patients with severe renal dysfunction were treated.RESULTS:It really existed that the vancomycin was irra?tionally used among these three patients:①The first loading doses did not match the saturation principle.②Administration interval did not be regulated in time along with the T 1/2 change.③The clinical doctors did not clearly understand that the hem_ odialysis can not efficiently remove vancomycin from the blood.CONCLUSION:For the infected patients with severe renal dysfunction,it is necessary to monitor the serum concentration of vancomycin in order to insure the rational use of vancomycin to treat these infected patients.

Objective To evaluate the protective effect of genistein on psoralens plus ultraviolet A (PUVA)-induced photoaging in human dermal fibroblasts (HDFs) in vitro.Methods Dermal fibroblasts were isolated from the foreskin of a healthy 5-year-old boy,and subjected to primary culture.After 5-8 passages of subculture,the fibroblasts were collected and used in the following experiment.To determine the optimal concentration of genistein,methyl thiazolyl tetrazolium (MTT) assay was conducted to detect the proliferation of fibroblasts pretreated with 8-methoxypsoralen (8-MOP) and various concentrations (0-20 μg/ml) of genistein for 24 hours followed by UVA irradiation.Then,the fibroblasts were divided into 3 groups:normal control group receiving no treatment,photoaging group incubated with 8-MOP for 24 hours followed by UVA irradiation,and genistein group incubated with both 8-MOP and genistein at the optimal concentration for 24 hours followed by UVA irradiation.After additional culture,invert microscopy was carried out to observe the morphology of fibroblasts,enzyme histochemistry to assess senescent cells by using SA-β-Gal kit,flow cytometry to determine the level of reactive oxygen species (ROS),real-time fluorescence-based quantitative PCR to detect the matrix metalloproteinase-1 (MMP-1) expression.One-way analysis of variance was conducted to assess the differences in these parameters among these groups.Results At 24 hours after UVA irradiation,the percentage of fibroblasts positive for SA-β-galactosidase was (0.67 ± 0.58)％,(96.67 ± 1.53)％ and (51.67 ± 2.08)％ in the normal control group,photoaging group and genistein group respectively,with significant differences among these groups (P ＜ 0.01).The level of ROS in the photoaging group and genistein group was (0.88 ± 0.24) and (0.62 ± 0.02) fold higher than that in the control group(both P ＜ 0.01).Moreover,the MMP-1 expression level in the photoaging group and genistein group was 10 times and 6 times that in the control group,respectively,with significant differences among the 3 groups (P ＜ 0.05).Conclusion In vitro,genistein can protect against PUVA-induced photoaging in human dermal fibroblasts to some extent.

Objective To observe the effects of Jieyu-Chufan capsule(JCC) on the behavior and the monoamine neurotransmitter content of cerebral in depression mouse model and explore its mechanism. Methods The ICR male mouse were randomly divided into seven groups according to their weights(the model group, the low, middle and high doses group, Baiyoujie group, the amitriptyline group, the normal control group). The low, middle and high doses group were given JCC with 1.250, 2.500, 5.000 g/kg separately by intragastric administration. Baiyoujie group was given 0.014 g/kg Baiyoujie by gavage. The amitriptyline group was given 0.050 g/kg amitriptyline by gavage. The model group and the normal control group received the same volume of distilled water intragastrically. The drugs were administrated once a day. The brepharoptosis and movement conditions of mouse were observed after 22 days. The monoamine neurotransmitter content of each group was measured after 25 days. Results Compared to the model group, the number of mouse with brepharoptosis decreased in the high dose group after 1, 2, 6 hour with reserpine injection (P<0.05 or P<0.01);the number of mouse came out from the circle increased after 4 hours with reserpine injection (P<0.05 or P<0.01);the content of NA (880.45 ± 428.81 ng/g, 875.98 ± 449.33 ng/g vs. 299.92 ± 267.08 ng/g) and DA (2 305.99 ± 530.37 ng/g, 2 169.99 ± 278.19 ng/g vs. 1 439.34 ± 357.33 ng/g) in the middle and high dose group increased (P<0.01);the content of 5-HT (781.43 ± 135.10 ng/g vs. 492.01 ± 192.80 ng/g) in the middle group increased (P<0.01). Conclusions JCC showed an antidepression influence in depression mouse model induced by reserpine. The mechanism may be related to regulating the level of monoamine neurotransmitter in the nervous centralis .

Objective To investigate the molecular epidemiology and risk factors of the expression of the efflux pumps of multidrug resistant Pseudomonas aeruginosa (Pa). Method From April 2014 to October 2014 , clinical features of 100 patients infected with multidrug resistant Pa were retrospectivly analyzed . Results MexAB-OprM was expressed in all multidrug resistant Pa strains (100%). The expression rates of MexEF-OprN and MexCD-OprJin the multidrug resistant Pa strains were 50% and 36%, respectively. The risk factor of the three efflux pumps expression was analyzed and the results were as follows: the use of carbapenems and glycopeptides antibiotics was the risk factor of MexAB-OprM overexpression which was induced. The use of macrolide and carbapenems antibiotics was the risk factor of the induced MexEF-OprN and MexCD-OprJ expression. Invasive procedures, low WBC, anaemia, chronic fundamental disease and hospitalized in ICU ward were the common risk factors of communicable expression or overexpression of the three efflux pumps. Invasive procedures, low WBC, anaemia, chronic fundamental disease and hospitalized in ICU ward were commonly independent risk factors of expression of the three efflux pumps. Conclusion The normalized use of carbapenems and glycopeptides antibiotics , the reduction of unnecessary invasive procedures , the severely grasped standard of hospitalized in ICU ward , curing the fundamental diseases and improving the immunonity played important roles in the prevention of the expression or overexpression of the efflux pumps of multidrug resistant Pa.
