ABSTRACT
Objective To understand the cleaning status of hospital environment,and evaluate the effect of fluo-rescence labeling method plus feedback and training on hospital environmental cleaning effectiveness.Methods A total of 27 departments in a hospital were investigated,1 cleaning staff and 2 inpatients were selected from each de-partment,cleaning staff’s knowledge about cleaning and disinfection of environmental object surfaces,as well as cleaning status of inpatients’wards were surveyed,cleaning efficacy of hospital environmental object surfaces were detected with fluorescence labeling method,the surveyed results were performed timely feedback to clinical depart-ments,training on cleaning and disinfection knowledge was conducted,the effective cleaning rate of environmental object surface before and after the training was compared.Results A total of 27 cleaning staff were surveyed,the correct response rate for cleaning frequency was 96.30% ,awareness rate for section concept was 96.30% ,accuracy rate of cleaning order was 92.59% ,accuracy rate of post-cleaning immersion time of sanitary wares in disinfectant was 85.19% ,accuracy rates of replacing,drying,and repeated immersing wiping cloths were 81.48% ,48.15% ,and 25.93% respectively,rates of correct disinfectant formulating method and mop drying time were both 0. Among 54 investigated patients,bed units and ground of wards of 28 patients were cleaned both 1-2 times/day;bed units of 8 patients had never been wiped,18 patients in 9 departments cannot be conducted statistics due to completely in-consistent responses with the other patients of the same departments. The effective cleaning rates of environmental object surfaces before and after the training were 34.62% and 64.96% respectively,difference was significant(χ2=21.81,P<0.01).Conclusion Fluorescence labeling method plus feedback and training can improve cleaning efficacy of hospital environmental object surfaces.
ABSTRACT
Objective To investigate the value of detecting plasma microRNA‐125a‐3p(miRNA‐125a‐3p) ,IGF‐2 on monitoring invasion and metastasis in NSCLC ,and to study the correlation between miR‐125a‐3p and IGF‐2 .Methods miR‐125a‐3p transcripts of 20 controls ,73 NSCLC were performed in plasma by quantitative reverse transcription‐polymerase chain reaction(qRT‐PCR) and PCR data was analyzed by the 2‐ΔΔCT method .The expression of IGF‐2 in plasma was detected by ELISA .Results The expression of miR‐125a‐3p in stage Ⅲ /Ⅳ was lower than stage Ⅰ/Ⅱ and the controls(P=0 .001 ,P=0 .005) .There was no statistical differ‐ence between the stage Ⅰ /Ⅱ patients and the controls(P=0 .776) .The expression of miR‐125a‐3p was related with lymph node metastas ,lower expression in positive lymph node metastasis (P=0 .003) .The expression of IGF‐2 in stage Ⅰ /Ⅱ 、stage Ⅲ /Ⅳ was higher than the controls(P=0 .036 ,P=0 .011) .There was no statistical difference between the stageⅠ/Ⅱ and stage Ⅲ/Ⅳ (P=0 .451) . The expression of IGF‐2 was related with lymph node metastas ,higher expression in positive lymph node metastasis (P=0 .037) .The re‐sults showed a negative correlation between miR‐125a‐3p expression and IGF‐2 in plasma(r= -0 .280 ,P=0 .007) .Conclusion Low ex‐pression of miR‐125a‐3p and high expression of IGF‐2 in plasma may play a role in invasion and metastasis of NSCLC .miR‐125a‐3p may play a negative regulatory role on IGF‐2 .
ABSTRACT
Objective: To explore the problem behaviors of high school students and its distribution among them. Methods: 1 739 middle school students in Beijing were collected as our sample (N=1739). Anonymous questionnaire of problem behavior of adolescents were used in this investigation. Results:1) the problem behaviors (general delinquency, cigarette smoking, and problem drinking) were significantly correlated with each other (r=0.28, 0.37, 0.39,P
