ABSTRACT
Objective To analyze the current status of bacterial spectrum and drug resistance in community-acquired biliary tract infection to provide a basis for clinical medication .Methods The patients with community-acquired biliary tract infection (ex-periment group) and the patients with biliary tract diseases without biliary tract infection (control group) derived from the native ar-ea treated in this hospital from September 2014 to January 2016 were selected .The bile juice was intraoperatively extracted for con-ducting the bacterial culture and drug susceptibility test .Results Thirteen specieses (60 strains) of bacteria were isolated in the ex-periment group .The top 3 specieses were Escherichia coli (35 .0% ) ,Klebsiella pneumonia (21 .7% ) and Enterobacter cloacae (10 .0% ) .Eight specieses (13 strains) of bacteria were isolated in the control group .The top 3 specieses were Escherichia coli (30 .8% ) ,Klebsiella pneumonia(15 .4% ) and Lactococcus garvieae (15 .4% ) .The proportions of drug resistant strains in the two groups were 95 .0% and 84 .6% respectively (P>0 .05) .The proportions of multiple drug resistant strains in the two groups were 30 .0% and 7 .7% respectively(P>0 .05) .The occurrence rates of multiple drug resistance in the top 3 specieses of bacteria in the experiment group were 61 .9% ,7 .7% and 16 .7% respectively .Conclusion The bacterial spectra of community-acquired acute bili-ary tract infection in the native area are dominated by Gram negative bacteria .The total bacterial drug resistance is serious ,but the drug resistance situation in different bacteria pathogens is different .
ABSTRACT
The aim of the present study, performed on two different groups of volunteers, is to characterize the pharmacokinetics of lisinopril/hydrochlorothiazide combined tablet. After administration of high, medium and low doses of lisinopril/hydrochlorothiazide combined tablets, AUC and C(max) of two compounds both increase significantly with increase of dose. Neither normalized AUC/Dose nor C(max)/Dose has significant difference between every two tested dose groups. The similar results can be observed as for the parameters of t(max). Lisinopril and hydrochlorothiazide are both eliminated with linear characteristics. After repeated administration of lisinopril/hydrochlorothiazide combined tablets, AUC, C(max) and C(min) of lisinopril in the steady state increase. AUC and C(min) increase significantly. As for hydrochlorothiazide, AUC, C(max), C(min), and t(max) also increase in steady state. AUC and C(min) increase significantly. Administered with the test medication, lisinopril has an fluctuation index (FI) value of 2.29 and reaches a relative steady concentration. But hydrochlorothiazide has an FI value of 4.09 with relatively large fluctuating concentrations.
ABSTRACT
Objective:To evaluate the action of arsenic trioxide(As 2O 3)on mitochondria of hepatic Vx-2 carcinoma by transcatheter arterial infusion(TAI).Methods:Fifty New Zealand rabbits weighing 2-3kg with hepatic Vx-2 carcinoma were randomly divided into five groups evenly.Two weeks after the tumor was implanted,the rabbits were treated with As 2O 3 (experimental groups),cisplatin or normal saline(control groups)by TAI for 7 days consecutively.Three weeks after drug administration,the mitochondrial morphological changes and mitochondrial specific surface areas of the tumor and hepatic tissues were investigated under transmission elcetron microscope,at the same time apoptosis of the tumor was observed.Results:The mitochondrial morphological changes of tumor were obvious in the experimential groups as compared with control groups( P
ABSTRACT
Objective To evaluate the anticancer effect of arsenic trioxide (As 2O 3) on rabbits with hepatic Vx 2 carcinoma by transcatheter arterial infusion (TAI). Methods Rabbits with hepatic Vx 2 carcinoma were treated with As 2O 3 by TAI for 7 d consecutively. The tumor inhibitory rate and the average tumor weight were determined. The morphological changes of the tumor were observed with a transmission electron microscope. bax/bcl 2 and VEGF expressions were examined by immunohistochemistry. Results The average weight of the tumor was 7.99, 6.50, and 4.87 g, and the tumor growth inhibitory rates in the experimental groups were 50.31%, 59 58%, and 69 71%, respectively. Tumor growth was significantly inhibited as compared with that in the NS group ( P
ABSTRACT
Objective To evaluate hepatic toxicity of arsenic trioxide(As 2O 3) on rabbits with hepatic Vx-2 carcinoma by transcatheter arterial chemoembolization (TACE), and its clinical signification. Methods New Zealand rabbits with hepatic Vx-2 carcinoma were managed with normal saline (experimental group 1), normal saline plus lipiodol (experimental group 2), and As 2O 3 plus lipiodol (experimental group 3) respectively by TACE once, whereas experimental group 4 was treated with As 2O 3 by transcatheter arterial infusion(TAI) for 7 days consecutively. The morphological changes of the tumor adjancent hepatic tissue were observed under light microscope and transmission electron microscope. The hepatic function of the rabbits was also determined. Results The hepatic cells of the rabbits in the experimental groups 2 and 3 were injuried in various degrees, but the injury extent was smaller than that in the experimental group 4 (P
