ABSTRACT
Objective@#To explore the effects of the intervention based on the theoretical framework of Health Belief Model on improving sharp injury protection behavior compliance of medical staffs, in order to provide some references for energetically developing blood-borne occupational exposure protection intervention in the region.@*Methods@#According to the inclusion criteria, 178 medical staffs were selected, implemented intervention of the theory of health belief model. Methods included diversity training, experiencing operation, filed observation and supervision and so on, strengthened intervention after 1 month, evaluated the intervention effect after 3 months, used questionnaires and field observation to evaluate the effect before and after the intervention.@*Results@#the scores of security behavior compliance were higher before intervention and there was significant difference (P<0.05) . Observed that, after the intervention the incidence of unsafe behavior in medical personnel dropped from 29.1% to 13.2%, the difference was statistically significant (P<0.05) .@*Conclusion@#The intervenion of the theory of health belief model can strengthen sharp injury protection belief of medical personnels, improve behavior compliance, reduces the occurrence of sharp injury.
ABSTRACT
Objective To analyze the difference of the venous port access (VPA) and peripherally inserted central catheter (PICC) in cancer chemotherapy.Methods All eligible studies on VPA and PICC were searched in the databases of PubMed,China National Knowledge Internet (CNKI),Chinese Biomedical Database (CBM),WANFANG Database and VIP Database.Literatures screening,quality evaluation and data extraction were conducted according to Cochrane Handbook;Meta-analysis was calculated by using RevMan 5.2.Results Twenty-nine studies with a total of 4 449 cases of patients were included in this Meta-analysis,with 1 912 cases in experimental group which adopted VPA and 2 537 cases in controlled group which adopted PICC.Experimental group had advantages in the average catheter retention time (SMD=3.36,95％CI 2.51-4.21) and quality of life (RR=1.61,95％CI 1.15-2.24) compared with controlled group.The overall complication rate (RR=0.26,95％CI 0.20-0.34,P＜0.01),phlebitis incidence (RR=0.08,95％CI 0.04-0.16,P＜0.01),catheter infection incidence (RR=0.32,95％CI 0.23-0.44,P＜0.01),catheter obstruction incidence (RR=0.32,95％CI 0.22-0.48,P＜0.01),catheter dystopy incidence (RR=0.18,95％CI 0.09-0.37,P＜0.01) in experimental group were remarkably lower than that in controlled group.However,no significant difference was found between the two groups in the incidence of the puncture success rate for the first time,errhysis or hematoncus,thrombus and catheter leakage (P ＞0.05).Conclusions Compared with PICC,VPA had advantages in a long retention time,fewer complications and few influence on quality of life.Therefore,VPA should be widely used in cancer chemotherapy.
ABSTRACT
Objective To investigate the expressions of COX-2 and VEGF-C in breast carcinoma and their correlation with lymphangiogenesis and lymph node metastasis. Methods The expressions of COX-2 and VEGF-C and D2-40 were evaluated in 46 cases of breast carcinoma by immunohistochemical staining SP methods. The lymphatic vessels density (LVD) in tumor was counted through the special marker D2-40. Results The positive rate of COX-2 and of VEGF-C was 73.91% (34/46) and 71.74% (33/46) respectively in breast carcinoma tissues. The positive rate of COX-2 and VEGF-C was 86.48% (32/37) and 81.08% (30/37), and LVD was (13.350?3.097)/?200 in the lymph node metastasis group, while that in non-lymph-node metastasis group was 22.22% (2/9), 33.33% (3/9) and (9.560?2.031)/?200 respectively, with significant difference between the two groups (P
