Objective To observe the influence of bezafibrate on the apoptosis and expression of lectin-like oxidized low density lipoprotein receptor-1(LOX-1) mediated by oxidized low density lipoprotein(ox-LDL) in cultured human umbilical vein endothelial cells(HUVECs).Methodes The apoptosis of HUVECs mediated by ox-LDL were evaluated by flow cytometry and the expression of LOX-1 mRNA were detected by RT-PCR.Results Compared with the control group,ox-LDL could increase apoptosis and the expression of LOX-1(P<0.05),and Bezafibrate could decrease the apoptosis and the expression of LOX-1 in a concentration -dependent manner(P<0.05).Preincubation of HUVECs with polyinosinic acid for 2 hours,the apoptosis and the expression of LOX-1 decreased(P<0.05).Conclusions Bezafibrate inhibits the apoptosis of HUVECs mediated by ox-LDL by reducing the expression of LOX-1,which may be part of the reasons for bezafibrate to prevent and treat atherosclerosis.

OBJECTIVE:To provide reference for promoting rational use of vancomycin in the clinic. METHODS:Referring to vancomycin instruction,Guiding Principles for Clinical Use of Antibacterials (2015 edition) and Chinese Expert Consensus on Clinical Use of Vancomycin (2011 edition),720 inpatient medical records of vancomycin were collected from our hospital during Jan. 2013-Dec. 2014,and then drug use of those inpatients were analyzed retrospectively. RESULTS:Among 720 cases,male (428 cases)was more than female(292 cases),and most of them aged 41-65(45.83%). There were 50 cases of prophylactic drug use(6.94%)and 670 cases of therapeutic drug use(93.06%). The patients came from 36 departments. Among 720 cases,the dose of 19 cases were higher than 2 g/d,and there were 13 ADR cases(1.81%). Among 670 cases of therapeutic drug use,587 cases of microbiological samples (87.61%) were detected,and other antibacterials were used in 522 cases additionally (77.91%). DUI of vancomycin was equal to 0.96 in 549 cases no younger than 18 years old of herapeutic drug use. There were 240 cases of unsuit-able drug use (33.33%) in total,including 192 cases of unsuitable solvent (26.67%),28 cases of unsuitable usage and dosage (3.89%)and 20 cases of unsuitable drug combination(2.78%). CONCLUSIONS:The use of vancomycin in our hospital is basi-cally rational;vancomycin is widely used in departments;drug combination is a common phenomenon;the inspection rate of mi-crobiological samples is qualified;no drug abuse is found. However,there still is inappropriate use in the clinic. It is recommended to strengthen special evaluation and training about rational use of vancomycin,and further standardize monitoring for vancomycin use so as to guarantee the safety of drug use.

Objective To investigate effect of high glucose on the function of endothelial and the underlying mechanisms in human umbilical vascular endothelial cells (HUVECs).Methods The experiment was divided into 4 groups: normal group (NG), low dose group (LG), middle dose group (MG) and high dose group ( HG) .The concentration of glucose in the culture medium was 5.5, 10, 20, 30 mmol/L in the 4 groups, respectively.The HUVECs was cultured for 0, 24, 48 h.At different time point, the cell viability were measured by MTT.The secretary content of nitric oxide (NO) in the supernatant were detected using test kit.The extraction of protein were extracted for Western blot analysis to detect the expression of endothelial nitric oxide synthase (eNOS).ResuIts Compared with normal group at same time point (cultured for 24 h), the cell viability and the content of NO were significantly decreased in LG, MG(P<0.05).The expression of eNOS in HG were markedly reduced (P<0.01).Compared with normal group at same time point (cultured for 48 h), the cell viability decreased significantly in HG (P <0.05).The expression of eNOS were markedly decreased 11.91, 25.72 and 34.50% in LG, MG and HG, respectively.A rising trend of cell viability were found in NG, LG and MG, but a descending trend were found in HG within 48 h.ConcIusion The cell viability were significantly affected by high glucose.The endothelial dysfunction induced by high glucose may be associated with the reduction of eNOS and NO production.

Objective To conduct a meta?analysis of literatures to explore the relationship of UGT1A1*6 gene polymorphism and irinotecan toxici?ty,so as to guide clinical treatment. Methods Papers were searched by PubMed database and manual search. The inclusion and exclusion criteria of studies were formulated and the methodologies quality was assessed,data were extracted and the statistical analysis was made using STATA12.0 software. Results A total of 12 articles were included according to the inclusion and exclusion criteria. Patients with mutated UGT1A1*6 showed an increased risk for neutropenia compared to wild UGT1A1*6(OR=2.37,95%CI 1.58?3.55,P=0.001). Both homozygous and heterozygous muta?tion showed an increased risk for neutropenia compared to wild type and the homozygous mutation(OR=5.09,95%CI 2.74?9.45,P<0.001) showed an even higher risk for neutropenia compared to the heterozygous mutation(OR=2.07,95%CI 1.37?3.13,P=0.001). For severe diarrhea, mutated UGT1A1*6 showed an increased risk compared to wild type(OR=1.48,95%CI 0.86?2.55,P=0.153),though without statistical signifi?cance. The homozygous mutation performed a significantly increased risk(OR=3.51,95%CI 1.33?9.25,P=0.011)and the heterozygous mutation also showed increased risk,however,the difference between them was not statistically significant. Conclusion UGT1A1*6polymorphisms can pre?dict irinotecan toxicity,especially for incidence of neutropenia.
