Objective To explore the application of bundle strategies in the management of multidrug-resistant or-ganisms(MDROs).Methods From July 1 ,2013,bundle intervention measures were applied in the management of MDROs from inpatients in a tertiary first-class hospital,the implementation of isolation measures for MDRO-infec-ted/colonized patients were monitored,April-June 2013 was pre-intervention group,July-September 2013 was the first stage of intervention,October-December 2013 was the second stage of intervention,the qualified rate of each measure and incidence of MDRO infection per 1 000 patient-days before and after intervention were compared. Results From April to December 2013,a total of 3 430 non-repetitive isolates were detected.The qualified rate of doctors’ order “contact isolation ”before intervention and in the second stage of intervention were 78.14% and 95.95% respective-ly;the qualified rate of hanging bed-side isolation signs,providing bed-side quick-drying hand disinfectant,and patients wearing blue wristbands before intervention were 52.70%,66.89%,and 87.16% respectively,and in the second interven-tion stage were all 100.00%.The qualified rate of disinfection of medical supplies and environment,as well as patients’ bed assignments before intervention were 23.65% and 15.54% respectively,in the second stage were 79.79% and 77.66% respectively.Health care workers’awareness rate of hand hygiene knowledge,hand hygiene compliance rate,and hand hygiene correct rate before intervention were 69.70%,45.76%,and 76.35% respectively;in the second stage were 90.23%,87.50%,and 94.58% respectively;the qualified rate of implementation of each isolation measure before inter-vention and in different stages after intervention were all significantly different(all P <0.01).The incidence of MDRO in-fection per 1 000 patient-days before intervention,in the first and second intervention stages were 3.24‰,2.63‰,and 2.20‰ respectively.Conclusion After the monitoring and intervention in MDROs with bundle management strategies,the qualified rate of each measure improved,incidence of MDRO infection per 1 000 patient-days decreased.

AIM To investigate antitumor effects of curcumin (Cur) combining with adriamycin (ADR) on human tumor cell lines in vitro and study the mechanisms. METHODS The antitumor effects of the drugs on tumor cell lines in vitro were determined with MTT method. The Jin's formula was used to analyze the effect of drug combination. Cellular ADR accumulation was measured by fluorescence spectraphotometry. RESULTS In simultaneous adiministration Cur 4 25～34 00 ?mol?L -1 combining with ADR produced a simple addition or potentiation effect. The cellular ADR accumulation was markedly increased in the presence of Cur in MDR cells, but decreased in sensitived cells. The experiment of membrane fluidity show that that Cur affects membrane fluidity neither on KB nor on KB v200 cell line. CONCLUSION Simultaneous adiministration of Cur combining with ADR produces synergistic effect. The mechanism is connected with increasing cellular ADR accumulationon on KB v200 cell line. While on KB cell line, it is related to synergistic pharmacological effect. But the action of Cur is not connected with the change of membrane fluidity on both cell lines.

Objective: To explore the dose-response relationship between duration of emotional experience of primary school students and the intensity of anxiety disorders, and to understand the risk of anxiety disorders corresponding to different emotional state levels. Methods: A total of 7 152 primary students from grade 3 to 5 were investigated with questionnaire survey from 16 public primary schools, by using the Screen for Child Anxiety Related Emotional Disorder (SCARED) and Positive Affect and Negative Affect Scale. Results: The prevalence of anxiety disorders was 19.91%, among which the prevalence rates of anxiety disorders in boys and girls were 19.41% and 20.43%, respectively. After adjusting for gender, grade, household register, the only child, parental marital status, parental occupation, parental educational level, family financial level, serving as a class leader, receiving special training or counseling in sports and art, and being bullied, the risk of anxiety disorder in children with positive emotions lasting for 7-16 days, 17-24 days and >24 days was lower compared to those with positive emotions lasting for less than 6 days(P<0.05); the risk of anxiety disorder in children with negative emotions lasting for 0.27-0.93 day, 0.94-2 days and >2 days was higher compared to those with negative emotions lasting less than 0.26 day(P<0.05). Restricted cubic spline analysis showed that the duration of emotional state and anxiety disorder showed a significant non-linear dose-response relationship (non-linear test, P<0.01), that is, as the number of days of positive emotions increases, the risk of anxiety disorder continues to decrease, and as the number of days of negative emotions increases, the risk of anxiety disorder continues to increase. Conclusion There is a significant dose-response relationship between the duration of the emotional state of primary school students and the prevalence of anxiety disorders. Acquirement and maintain positive emotions m be an important entry point for mental health promotion among primary school students.

Objective: To investigate and compare the prevalence of distracted walking and determinants between general high school and vocational high school students and to provide a reference for the targeted interventions. Methods: A total of 1 777 senior high school students from 4 general high schools and 2 vocational high schools in Shanghai were selected for online questionnaire survey in December 2018 through convenience sampling. The questionnaire included demographic information and behaviors related to distracted walking. Results: In different road environments and crosswalk type, cell phone was used most frequently when waiting for traffic lights and when walking in housing estate roads in general high school students(24.6%,21.2%) and vocational high school student(18.8%,21.4%). More students from vocational schools reported smartphone use while walking in all road type except housing estate road(χ2=30.47,13.22,90.72,79.01,29.88,P<0.01). Listening to music was the main use of mobile phone when walking, students who spent more than half of their walking time listening to music were 31.2% at general high school students and 24.2% at vocational high schools; the need to access information is the primary motivator for smartphone use while walking. Nearly 50% participants realized smartphone use while walking could increase the risk of risky behaviors including inattention to traffic signals and status. About 30% general school students and 50% vocational school students agreed that tips, sprains and traffic collisions associated with distracted walking. Conclusion Currently, distracted walking is common among high school students, especially for vocational high school students. Pedestrian safety education should be incorporated into school-based education, together with education from parents, peers and the society, with the aim of increasing safety awareness.

Objective: To understand the epidemiologic characteristics of fall in the elderly in Shanghai, as well as the differences between urban and rural areas, and provide evidence for targeted fall prevention and intervention. Methods: From January to March in 2017, a questionnaire survey was conducted in the elderly aged 60 or above selected from 7 urban communities and 6 rural communities in Shanghai to understand the epidemiologic characteristics of fall in the elderly and analyze the gender and urban-rural differences. Results: In urban area, a total of 3 386 elderly people were surveyed, in whom 441 (13.0%) had fall and 261 (7.7%) were injured after fall. In rural area, a total of 2 826 elderly people were surveyed, in whom 320 (11.3%) had fall and 169 (6.0%) were injured after fall. Fall risk in women were higher than that in men in both urban and rural areas with OR of 1.62 (95%CI: 1.42-1.86) and 1.16 (95%CI: 1.38-1.98) respectively, but the differences of fall related injury were not significant. Compared with urban areas, fall risk and fall related injury risk were both lower in rural areas with OR of 0.86 (95%CI: 0.73-0.99) and 0.74 (95%CI: 0.56-0.99). Compared with urban areas, men had lower risk for fall, and women had lower risk for fall related injury with OR of 0.68 (95%CI: 0.51-0.90) and 0.66 (95%CI: 0.47-0.93) respectively. Fall mainly occurred at home. Fall in urban area more frequently occurred on stairs, and fall in rural area more frequently occurred during farming. More than 60% of the falls had environmental risk factors. Slippery ground and uneven ground were main reasons. The incidence of fracture resulted from fall was high indicated by 89 fracture cases in urban areas (28.2%) and 64 fracture cases in rural areas (36.1%). Conclusions The risk for fall in Shanghai had gender and urban-rural differences. Targeted intervention should be conducted according to the characteristics of fall in the elderly.

Objective: To observe the effect of chorioamnionitis on placental microvessel and platelet metabolism in premature and the correlation between them. Methods: With clinical randomized controlled trial (RCT), the cases were matched by 11 according to gestational ages and divided into 2 groups according to the placental pathology results: chorioamnionitis group and control group, 32 cases in each group.Dates were obtained for preterm infants (gestational age<37 weeks) admitted to the Department of Neonatology at Guangdong Women and Children Hospital, born between June and December 2016.The platelet parameter [platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT)], birth weight, thrombocytopenia, hemorrhage complication, miscrovascular density (MVD) in placenta, platelet activating factors (CD_62p, CD₆₃) and thrombopoietin (TPO) in preterm infants were recorded and compared. Results: In chorioamnionitis group, the infant birth weight[(1.90±0.41) kg vs.(2.31±0.62) kg] and the PLT in 72 hours [<24 h (197.97±63.43)×10⁹/L vs.(266.34±69.92)×10⁹/L; 24-72 h (202.28±29.70)×10⁹/L vs.(256.38±69.96)×10⁹/L] were significantly lower compared with the control group, and the differences were statistically significant(all P<0.05). The incidence of early thrombocytopenia(37.50% vs.9.38%), intracranial hemorrhage(40.62% vs.15.63%), MPV [(8.73±0.89) fL vs.(8.27±0.64) fL] and PDW[(59.46±5.90)% vs.(55.20±5.37)%] in 24 hours were significantly higher in chorioamnionitis group, and the differences were statistically significant (all P<0.05). The placental MVD in chorioamnionitis group significantly decreased[(9.08±1.35)% vs.(12.89±1.36)%, P<0.05 ]. The level of CD_62p, CD₆₃ and TPO in umbilical cord blood were significantly higher in chorioamnionitis group[(25.37±5.20)% vs.(10.35±2.94)%, (9.49±1.58)% vs.(4.04±1.21)%, (271.08±197.22) μg/L vs.(141.87±78.10) μg/L, all P<0.05]. The placental MVD was positively associated with PLT (r=0.74, P<0.05) and negatively associated with CD_62p, CD₆₃ and TPO among infants with chorioamnionitis (r=-0.64, -0.44, -0.44, all P<0.05). Conclusions The chorioamnionitis may decrease the MVD in placenta and activate platelet in fetal circulation, damaged placental microvessel may activate platelet further.
