Objective To investigate the effect of targeted monitoring on the control of central venous catheter associated infection, study the difference of CVC?RI infection rate and the distribution of pathogenic bacteria in the general hospital and the maternal and child hospital, and analyse the main pathogenic bacteria drug resistance characteristics. Methods From January 2013 to December 2014,685 cases patients with central venous catheterization in the Port Hospital of Hebei Port Group Company Limited,and four cooperative hospitals ( Affiliated Hospital of North China University of Science and Technology, People′s Hospital of Tangshan, Tangshan Port Economic Development District Hospital, Maternal and Child Health Care Hospital of Laoting County) were selected as the research objects. The difference of infection rate before and after the targeted monitoring in 2014 was compared. The tip of the catheter and the peripheral blood were cultured in the patients with suspected infection,bacterial identification and drug sensitivity test were carried out using Compact VITEK2 automatic bacteria identification/drug sensitivity analyzer. Results The infection rate of CVC?RI of five hospitals was 18. 75%( 60/320 ) in 2013, 11. 51%( 42/365 ) in 2014, the difference of infection rate was statistically significant before and after the implementation of the target monitoring(χ2=7. 059,P<0. 05) . The CVC?RI infection rate was 15. 52%(81/522) in the general hospital,12. 88%(21/163) in the maternal and child hospital,the difference was not statistically significant(P>0. 05). In 102 cases of CVC?RI,105 bacterial strains were detected in 91 cases,gram positive bacteria accounted for 51. 43%( 54/105) ,gram negative bacilli accounted for 40. 95%( 43/105) ,fungi accounted for 7. 62%( 8/105) . There was no significant difference in the proportion of pathogenic bacteria in the general hospital and the maternal and child hospital(P>0. 05). Grampositive cocci were mainly staphylococcus aureus and coagulase negative staphylococci,they were completelysensitive to linezolid, quinupristin/ dalfopristin, tigecycline, and vancomycin. They were high sensitivity torifampicin,while highly resistant to gentamicin, tetracycline, penicillin; Gram negative bacilli were mainlypseudomonas aeruginosa and escherichia coli,they were high sensitivity to meropenem,imipenem,while resistantto multiple antimicrobia1s. Conclusion Adhere to the implementation of targeted monitoring help to reduce theoccurrence of CVC?RI. The isolation of pathogenic bacteria from multiple drug resistance should be paid moreattention.

BACKGROUND:There are less reports on the evaluation of plantar pressure distribution in knee osteoarthritis patients using modern gait analysis, and moreover, the database of characteristic plantar pressure has not been established in patients with osteoarthritis. OBJECTIVE: To evaluate the therapeutic effect of Chinese massage and functional exercise on knee osteoarthritis. METHODS:Forty patients with left knee osteoarthritis who were eligible for the inclusive criteria were randomized into two groups, with 20 in each group. Control group was given conventional treatment, and treatment group was given Chinese massage combined with functional exercise. Japanese Orthopaedic Association score and gait parameters were measured and compared between two groups before and at 3 months after treatment. RESULTS AND CONCLUSION:After treatment, the two groups both had evident efficacy in pain relief during walking, and there was no statisticaly difference between the two groups. There was a significant difference in the knee range of motion in the patients in the treatment group when going upstairs and downstairs as wel as during joint flexion before and after treatment, but no changes occurred in the control group. After treatment, the range of motion during joint flexion was better in the treatment group than the control group, but there was no difference in the sweling reduction between the two groups. In addition, the treatment group had a higher Japanese Orthopaedic Association score after treatment than before treatment (P < 0.05), and there was no statistical difference in the control group. Gait analysis showed that there were improvements in the percentage of contact time, parameters during stance phase and peak plantar pressure in the two groups, but there was no significant difference before and after treatment. Foot axis angle in the treatment group was improved significantly, which was significantly better than that in the control group. Al the indexes in the treatment group were improved a lot, but did not reach the normal.

Objective To investigate the prevalence of psychological distress and analyze the relevant factors among patients with bladder tumor so as to provide evidence for future clinical practice. Methods Totally 128 patients were recruited from a urological surgery ward of a comprehensive hospital in Beijing in the study by using self-design questionnaire and the psychological distress thermometer (DT) recommended by the U.S. national comprehensive cancer network (NCCN). The acquired data were analyzed by SPSS17.0. Results The average score of the patients was 4.00(1.00~5.00). The identification rate of psychological stress was 55.47%( 71/128 ) , higher than the Chinese normal ( U = 8 . 28 , P < 0 . 05 ) . The relevant factors of psychological stress based on the rank from high to low scores included emotion problems ( 1 . 63 ± 0 . 67 ) , practical problems ( 1 . 42 ± 0 . 64 ) , communication problems (1.29 ± 0.65), physical problems (1.28 ± 0.33) and religion problems (1.00 ± 0.08). Conclusions The prevalence of psychological distress is higher among patients with bladder tumor and the influence factors mainly include emotional problems , practical problems and communication problems. Nurses should pay attention to the psychological distress of patients with bladder tumors and develop targeted interventions so as to relieve their distress.
