RESUMO
Purpose To investigate the effects of chemotactic factor CCR4 on the abi1ity of pro1iferation,ce11 cyc1e,invasion,and mi-gration of human ga11b1adder cancer ce11. Methods Western b1ot was used to detect the expression 1eve1 of CCR4 in ga11b1adder carci-noma ce11s. Ga11b1adder carcinoma ce11s was infected by means of s1ow virus,the CCR4 gene si1encing was conducted using siRNA-CCR4 interference techno1ogy. Ga11b1adder carcinoma ce11s GBC-SD were divided into three groups( GBC-SD,GBC-SD/CCR4-RNAi and GBC-SD/contro1). CCL17,a 1igand of CCR4,was used to act on these three groups of ce11s. CCK8 method was used to detect the ce11 pro1iferation abi1ity of three groups. F1ow cytometry was used to test ce11 cyc1e. Tanswe11 assay was app1ied to detect ce11 migration and invasion abi1ity. Western b1ot was performed to detect the expression of its corresponding 1igands CCL17 and CCL22 proteins. Re-sults CCR4 gene si1ence did not inf1uence ce11 cyc1e and pro1iferation of ga11b1adder ce11 GBC-SD,but can significant1y inhibit GBC-SD ce11 invasion and movement abi1ity,CCR4 gene si1ence had no inf1uence on the expression of CCL17 and CCL22 gene in tumor ce11s. Conclusion Ga11b1adder carcinoma ce11s GBC-SD express chemokine receptor CCR4,chemokine receptor CCR4 can promote the invasion and metastasis of GBC-SD ce11s.
RESUMO
OBJECTIVE:To provide reference for rational use and standard management of antibiotics. METHODS:The relevant information for antibiotics used in the inpatients of our hospital involved in antibiotics special rectification during 2011 to 2014 were extracted from hospital information system,and the relevant data of antibiotics use were analyzed statistically. The changes of several indicators in the inpatients of our hospital were investigated,including the utilization rate and amount of antibiotics,DDDs and the uti-lization rate of typeⅠincision antibiotics for prophylactic use. RESULTS:The ratio of consumption sum of antibiotics in total con-sumption sum were decreasing from 2011 to 2014. The utilization rate of antibiotics and of typeⅠincision antibiotics for prophylactic use were decreased significantly,decreasing from 77.30% and 47.57% in 2011 to 57.24% and 5.89% in 2014. The consumption sum of cefepime occupied the first 3 places in 3 years. DDDs of cefotaxime and cefoperazone/sulbactam occupied the first 2 places in 4 years. CONCLUSIONS:The development of“antibiotics special rectification activities”have achieved remarkable results in our hospi-tal,the various index of antibiotics in the inpatients have been obviously improved,and clinical application of antibiotics become more reasonable,which lay a good foundation for continuous improvement of clinical application and management of antibiotics.
RESUMO
ObjectiveTo evaluate the influence of electrotome on permanent and temporary cardiac pacemaker in laparoscopic cholecystectomy ( LC),and the application of cardiac pacemaker to the cases of cholecystolithiasis combined with bradyarrhythmia.MethodsClinical data of 215 patients with permanent or temporary cardiac pacemaker who underwent were studied for the preoperative and postoperative variation of pacemaker function,and for the influence of electricity coagulation during the operation on cardiac pacemaker function.ResultsLC was successfully completed in all 215 patients.The function of cardiac pacemaker was not obviously interfered during the operation,and the parameters of cardiac pacemaker did not remarkably change after the operation.ConclusionCardiac pacemaker is slightly interfered when electrotome and electrocoagulation were used in LC; LC is feasible and safe for patients with bradyarrhythmia by placement of cardiac pacemaker.
