| 1 | Prehospital system delay in patients with ST-segment elevation myocardial infarction in Singapore显示文摘BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction(STEMI)improves outcomes. System delay is that between first medical contact and reperfusion therapy,comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore.METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services(EMS),ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique.RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5minutes(interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes(IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes(IQR=1.30, 22.13); between arrival-at- and departurefrom-patient-location was 13.12 minutes(IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes(IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulancedispatch and arrival-at-patient-location was shorter(5.75 vs. 9.37 minutes, P<0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter(10.78 vs.14.37 minutes, P<0.01).CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care. | Andrew Fu Wah Ho Pin Pin Pek Stephanie Fook-Chong Ting Hway Wong Yih Yng Ng Aaron Sung Lung Wong Marcus Eng Hock Ong | 2015 | World Journal of Emergency Medicine2015，6，4： | 6 |
| 2 | 蒌叶提取物增强5-氟尿嘧啶对结肠癌细胞HT29和HCT116的生长抑制作用(英文)显示文摘研究目的:探讨蒌叶(PB)提取物对5-氟尿嘧啶(5-FU)抑制结肠癌细胞HT29和HCT116生长的影响。研究方法:HT29和HCT116细胞分别给予PB、5-FU以及两种药物联合治疗24小时,应用等效线图法分析PB和5-FU的药效学相互作用,Annexin V/PI染色法检测HT29和HCT116细胞的凋亡情况,高效液相色谱法排除PB和5-FU间任何可能的相互化学作用。重要结论:联合PB,低剂量5-FU可以在短时间内起到细胞毒作用,而单独应用PB或5-FU治疗较联合治疗可以诱导更多细胞发生凋亡。进一步采用等效线图法分析显示PB和5-FU的联合作用在抑制结肠癌细胞HT29和HCT116的生长中分别体现出协同和拮抗作用。因此可以认为在HT29细胞中,PB使得较低剂量5-FU发挥最大抑制结肠癌细胞生长效果,然而在HCT116细胞中,PB没有显著降低5-FU的药物浓度,说明PB和5-FU的相互作用不仅仅体现在诱导细胞凋亡方面。 | Pek Leng NG Nor Fadilah RAJAB Sue Mian THEN Yasmin Anum MOHD YUSOF Wan Zurinah WAN NGAH Kar Yong PIN Mee Lee LOOI | 2014 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014，15，8： | 1 |
