Objective To investigate the distribution of carbapenemase-resistant genes carried by multi-drug resistant Acineto-bacter baumannii .Methods 80 strains of multi-drug resistant Acinetobacter baumannii were collected .Polymerase chain reaction (PCR)wasusedtodetectcarbapenemase-resistantgenes,suchasOXA-23,OXA-24,OXA-51,OXA-58,SIM,IMP,VIM ,GIMand SPM ,in multi-drug resistant Acinetobacter baumannii .Results Drug resistant gene OXA-23 [49 (61 .3% )] ,OXA-51 [73 (91 .3% )] ,OXA-58[7(8 .8% )] ,OXA-24[1(1 .3% )] ,IMP[17(21 .3% )] and VIM[2(2 .5% )] were found in 80 strains of multi-drug resistant Acinetobacter baumannii ,while GIM ,SIM and SPM gene were not found .Conclusion IMP ,OXA ,VIM is the main genotypes carried by multi-drug resistant Acinetobacter baumannii .

Objective: To study the effects of supplemented Yang Supplementing Five Returning Decoction on the blood lipid and immune function of the model mouse. Methods: Supplemented Yang Supplementing Five Returning Decoction is composed of Yang Supplementing Five Returning Decoction, Herba Epimedii and propolis. The effects of two formulae, Yang Supplementing Five Returning Decoction and Supplemented Yang Supplementing Five Returning Decoction on the blood lipid, the functions of nonspecific immunity, humoral immunity and cellular immunity were investigated on the normal and hyperlipemia rat models and immunosuppressive mouse model. Results: Supplemented Yang Supplementing Five Returning Decoction could not only maintain the original formula functions of lowering TC. TG and LDL C of rats ( P

Objective:To investigate the safety and efficacy of self-made multifunctional endoscopic instrument accessory stent in endoscopic mucosal dissection (ESD).Methods:A total of 80 patients who received ESD in 924th Hospital of Joint Logistic Support Force of Chinese People′s Liberation Army from May 2019 to February 2021 were selected as research object. Random number table method was used to divide patients into control group and experimental group, 40 cases in each group. The experimental group used self-made endoscopic instrument accessory stent, and the control group did not use self-made endoscopic instrument accessory stent. The length of operation, the number of instruments taken by mistake, the number of instruments polluted during operation and the infection of postoperative 3-7 days under the same operation position, operating doctors and nurses were analyzed and compared between the two groups.Results:The incidence of instruments taken by mistake, the incidence of instruments polluted during operation and the infection rate of postoperative 3-7 days were 0.9% (8/856), 1.4% (12/856) and 2.5% (1/40) in the experimental group, which in the control group were 10.8% (96/887), 11.8% (105/887) and 15.0% (6/40) respectively, there were significant differences between the two groups ( χ2=75.92, 75.76, 3.91, all P<0.05). The length of operation in the experimental group was (51.56 ± 2.32) min, and that in the control group was (79.02 ± 2.83) min, the difference was statistically significant ( t=-8.72, P<0.05). Conclusions:When the patients underwent ESD surgery, the self-made multifunctional accessory stent was used to place the required instrument accessory. The length of operation was shorter, the incidence of instruments taken by mistake, the incidence of instruments polluted during operation and the infection rate of postoperative 3-7 days were reduced, the quality of minimally invasive endoscopic surgery was improved.
