1.New progress on research of catheter-related bloodstream infection
International Journal of Surgery 2012;39(1):30-33
The major pathogenic bacterium of catheter-related bloodstream infection is gram-positive bacteria.The occurrence of catheter-related bloodstream infection is related with exogenous factors and endogenous factors.It is suggested that catheter-related bloodstream infection should be diagnosed without removing the catheter.It is shown that the catheter should be removed and the patient should use antibiotics as soon as possible if catheter-related bloodstream infection occurred.Buliding a detection system,using antimicrobial dressings and antimicrobial central catheters,and improving patient's nutritional status can decrease the morbidity of catheter-related bloodstream infection.The authors summarize the epidemiology,diagnosis,treatment and prevention strategies of catheter-related bloodstream infection.

Chinese Archives of Otolaryngology-Head and Neck Surgery 2017;24(7):351-354
OBJECTIVE To investigate the relationship between state trait anxiety and behavioral status in patients with sudden deafness. METHODS From April 2015 to June 2016, 140 cases of hospitalized patients with sudden hearing loss were selected as the observation group, and 140 healthy volunteers in our hospital for medical examination were selected as the control group. Average data, state trait anxiety, quality of life, and behavior survey were investigated in the two groups and correlation analysis was conducted. RESULTS The state trait anxiety score of the observation group was 51.20±4.19 points, and the control group was 34.40±3.49 points, and the state trait anxiety score of the observation group was significantly higher than that of the control group(t=12.949, P<0.05). The scores of physical, compulsive, interpersonal sensitivity, hostility and depression in the observation group were significantly higher than those in the control group(P<0.05). The problem solving and help scores in the observation group were significantly lower than that of the control group, while the fantasy and self accusation scores was significantly higher than that of the control group(P<0.05). In the observation group, Pearson correlation analysis shows anxiety scores were significantly correlated to the dimensions scores of quality of life, fantasy and self accusation scores(P<0.05), and were significantly negative correlated to the problem solving and help scores (P<0.05). CONCLUSION The patients with sudden deafness is accompanied by state trait anxiety and fantasy, self accusation and other bad behavior, it can seriously affect the patient's quality of life and form vicious circle, so the nursing intervention should be strengthened in clinical practice.

Objective To investigate the incidence of nosocomial infection of placing peripherally inserted central catheter (PICC) and venous port acess(VPA) in children with leukemia. Methods 60 cases with leukemia were treated in our hospital from January 2005 to September 2009.35 cases were mail, 25 cases were femail.Their ages ranged from 2.0 to 16.5 years old.42 cases fell to the PICC group, hospital-ization for 202 times, 18 cases belonged to the VPA group, hospitalization for 109 times. The incidence of infection in hospital, infection site, common pathogens and prognosis of two groups were analyzed retro-spectively.Results The incidence of fever and increasing of C-reactive protein of the PICC group were significantly lower than those of the VPA group. There was no difference of the incidence of white blood cells decreasing between two groups. The incidence of infection in hospital in the PICC group was 38.61%, higher than 28.44% of the VPA group. Their difference was significant. There was significant difference of the distribution of infection between two groups. There was no significant difference of the major pathogens of sputum culture and blood culture between two groups. Conclusions Using venous port acess(VPA) could reduce the incidence of infection in hospital compared using peripherally insertied central catheters in children with leukemia, so venous port acess( VPA ) may be safer.
