Results No surgical accident happened after application of "Time-out" procedure in opera tion room of Hongkong Mary Hospital. Conclusions Preoperative "Time-out" procedure is one of the important measure to ensure the safety of surgical patients and prevent surgical accident. Managers in operation room should popularize this process according to actual situation in order to guarantee correct surgery on correct part of correct patients.

AIM:To investigate the injurious effects of oxidized low-density(OLDL) on human endothelial cells(ECs) and protective effects of Angelica Sinensis in vitro. METHODS: The effect of OLDL on nitric oxide (NO) release from EC and intercellular adhesion molecule-1 (ICAM-1) expression on EC surface were studied, and the protective effects of Angelica Sinensis on normal and abnormal EC were investigated using cultured EC with or without OLDL and immunocytochemical staining technique. RESULTS: OLDL led to a decrease of NO release and an increase of ICAM-1 expression, which can be reversed by Angelica Sinensis and atropine can block this role of Angelica Sinensis. CONCLUSION: Angelica Sinensis has antagonistic effect on OLDL-induced decreasing of NO released from ECs and increasing of ICAM-1 expression on ECs surface . These effects of Angelica Sinensis may be exerted by the excitation of muscarinic receptor.

Objective To compare the effect of GammaTM wet wipes and 75% alcohol on the disinfection of X-ray protective clothing,and provide reference for choosing rational disinfection methods.Methods 62 pieces of X-ray protective clothing were selected,30 were from operating rooms,32 from catheterization room.Protective clothing were randomly divided into trial group and control group,each had 31 pieces.Trial group disinfected clothing with GammaTM wet wipes,control group disinfected clothing with 75% alcohol,disinfection effect,drying time,and cost between both groups were compared.Results Average bacterial colony counts in trial group and control group before disinfection were 2.38 CFU/cm2 and 2.36 CFU/cm2 respectively,qualified rates were 80.64% and 83.87%respectively.Bacteria were not detected in both groups after disinfection.The average drying time in trial group was shorter than control group([352.35±9.93]s vs[676.13±10.62]s,t=123.98,P <0.01).The cost of disinfecting X-ray protective clothing in trial group was 29.60% less than control group.Conclusion Effect of GammaTM wet wipes and 75% alcohol on disinfecting X-ray protective clothing are both reliable,compared with 75% alcohol, GammaTM wet wipes are without corrosion,have shorter drying time,and save more cost.

AIM To investigate the anti oxidation activities of new systhesized nitroxides in liver, liver mitochondria and RBC from rats and in egg phospholipid. METHODS The homogenates of liver, liver mitochondria from rats and the suspensions of egg phospholipid were used to determine malondialdehyde (MDA) formation induced by Fe 2+ Vit C system using TBA colorimetric method. H 2O 2 caused hemolysis was measured spectrometrically. Superoxide anion was assayed spectrometrically. RESULTS Nitroxides A, B with one active group (NO?) could inhibit MDA generation caused by ?OH generation system significantly, antagonized hemolysis induced by H 2O 2, but did not affect O ? 2 formation; Nitroxide C with two active group (NO?) possessed similar potent anti lipoperoxidative activities,IC 50

Objective To discuss the relationship between repetitive variable deceleration with a short interval (RDSI) in labor and neonatal acidosis.Methods One hundred and seventy-seven electronic fetal heart monitoring (EFM) patterns within one hour preceding delivery in term singleton pregnancies were collected in Peking University Third Hospital between February 2011 to October 2013.Continued EFM were recorded before delivery.Analysis was conducted on general information of both mothers and babies,including pregnant complications,duration of labor,cord and placental factors,nature of amniotic fluid,Apgar score and neonatal cord blood gas.RDSI was defined as that over 50％ intervals between two decelerations (the end of the last deceleration to the beginning of the next one) ≤ 60 s which appeared repetitevly in a period of 20 minutes.Independent sample t test,rank sum test,Chi-square test and Fisher's exact test were applied for statistics and receiver operating characteristic curve was obtained from the information of those with RDSI.Results Twenty-four of the 177 women with RDSI were assigned to the study group (24 cases,13.6％) and the rest 153 cases without RDSI to the control group.Background information of women in the two groups was comparable according to the maternal age,gestational weeks at delivery and duration of labor (all P ＞ 0.05).The occurrence of meconium stained amniotic fluid in the study group was higher than that of the control group [16.7％ (4/24) vs 5.2％ (7/153),x2=5.204,P=0.045],while the pH and base excess value of the neonatal blood gas in the study group were lower [7.20 (7.13-7.28) vs 7.29 (7.25-7.33),Z=-4.490;-6.10 (-4.67 to-9.62) mmol/L vs-3.20 (-4.90 to-1.55) mmol/L,Z=-5.044;P ≤ 0.01] resulting a higher rate of neonatal acidosis [50.0％(12/24) vs 7.8％ (12/153),x2=31.456,P ＜ 0.01].No significant difference was found in the incidence of neonatal asphyxia between the two groups.The area under the curve was 0.774 (95％CI:0.579-0.969).Conclusion RDSI in labor might indicate a high risk of neonatal acidosis.

Aim To screen the differentially expressed microRNAs ( miRNAs ) induced by hypoxia precondi-tioning ( HPC ) in adult rat cardiomyocytes, and pre-dict miRNAs-regulated target genes and their func-tions. Methods Cardiomyocytes were isolated from a-dult rat ventricular myocardium and cultured ( in vitro) . The cells were divided into 2 groups: control group ( CON ) and hypoxia preconditioning group ( HPC) . The cardiomyocytes in HPC group were sub-jected to 10 min hypoxia followed by 30 min reoxygen-ation, while the cells in CON group were cultured un-der normal condition. After that, total RNA was ex-tracted and then subjected to miRNA microarray to screen differentially expressed miRNAs. The microar-ray results were further validated by quantitative RT-PCR ( qRT-PCR ) . Bioinformatics analysis was per-formed to predict the miRNAs-regulated target genes and analyze the enriched gene ontology ( GO) and sig-naling pathway ( Pathway) . Results HPC caused sig-nificant changes in miRNAs expression in cardiomyo-cytes as compared to CON group. A total of 12 miR-NAs were up-regulated and 14 miRNAs were down-reg-ulated ( P <0. 01 , FDR <0 . 05 ) . The differentially expressed 7 miRNAs with a fluorescent signal intensity>500 were selected for further bioinformatics analysis. The expression of miR-133b-5p, miR-664-1-5p and miR-6216 detected by qRT-PCR exhibited the similar patterns of up or down regulation to those shown in mi-croarray results. Bioinformatics analysis revealed that miRNAs-regulated target genes were significantly en-riched in 27 GOs and 6 signal pathways. Conclusion
The expression profile of miRNAs in rat cardiomyo-cytes is significantly affected by HPC. These differenti-ally expressed miRNAs might participate in HPC-in-duced cardioprotection by regulating their target genes in rat cardiomyocytes.
