Evidence suggests that in the event of a fire accident, a certain number of building occupants escape through smoke-filled environments. Consequently, evaluating the corresponding evacuation performance under such life-threatening conditions is important for advancing fire safety analyses. This study aimed to develop a fire-integrated evacuation model to consider the effects of spreading fire hazards (i.e., radiation, temperature, toxic gas, visibility) on evacuees in a room fire evacuation scenario. Furthermore, a novel quantitative approach was introduced to evaluate evacuees’ local fire risks and stress levels according to their egress paths. The escape characteristics at various stages of fire development were studied as well. The results demonstrate that evacuation performance varies considerably depending on the severity of evacuees’ confronted fire hazard conditions, which emphasizes the importance of minimizing the pre-evacuation time in fire evacuation emergencies.

Background Childhood cancer survivors were at risk of development of second malignant neoplasms. The aim of this study is to evaluate the incidence, risk factors and outcome of second malignant neoplasms in childhood cancer survivors in a tertiary paediatric oncology centre in Hong Kong, China. Methods We performed a retrospective review of patients with childhood cancer treated in Children＇s Cancer Centre in Prince of Wales Hospital, Hong Kong, China between May 1984 and June 2009. Case records of patients who developed second malignant neoplasms were reviewed. Results Totally 1374 new cases aged less than 21-year old were treated in our centre in this 25-year study period. Twelve cases developed second malignant neoplasms with 10-year and 20-year cumulative incidence of 1.3% （95% confidence interval 0.3%-2.3%） and 2.9% （95% confidence interval 1.1%-4.7%） respectively. Another 4 cases were referred to us from other centres for the management of second malignant neoplasms. In this cohort of 16 children with second malignant neoplasms, the most frequent second malignant neoplasms were acute leukemia or myelodysplastic syndrome （n--6） and central nervous system tumor （n=4）. Median interval between diagnosis of primary and second malignant neoplasms was 7.4 years （range 2.1-13.3 years）. Eight patients developed second solid tumor within the previous irradiated field. Radiotherapy significantly increased the risk of development of second solid tumor in patients with acute lymphoblastic leukemia （P=0.027）. Seven out of 16 patients who developed second malignant neoplasms had a family histo＇ry of cancer among the first or second-degree relatives. Nine patients died of progression of second malignant neoplasms, mainly resulted from second central nervous system tumor and osteosarcoma. Conclusions Cumulative incidence of second cancer in our centre was comparable to western countries. Radiotherapy was associated with second solid tumour among patients with acute lymphoblast

BACKGROUND Cetuximab in combination with oral fluoropyrimidine(FP)remains controversial in metastatic colorectal cancer(mCRC).In view of the regional variation in the tolerability of FP,we conducted a retrospective analysis to compare oral FP with infusional FP in combination with cetuximab in Chinese *** To compare the efficacy and safety profile of cetuximab in combination with oral FP and infusional FP in Chinese population in the real-world *** A retrospective cohort study was done to analyse consecutive patients with Kras wild-type mCRC who received first-line treatment with cetuximab and FP-based chemotherapy in our unit from January 2010 to December ***-five eligible patients were *** median follow-up of our cohort was 65.0 *** The median progression-free survival(mPFS)and median overall survival(mOS)of the entire cohort were 9.66 mo(95%CI:7.72–12.5)and 25.8 mo(95%CI:18.7–35.6),*** oral FP and infusional FP,there was no statistical significant difference in the mPFS[9.79 mo(95%CI:7.49–12.7)vs 9.63 mo(95%CI:6.34–13.4);P=0.72]and mOS[25.8 mo(95%CI:15.2–35.6)vs 26.3 mo(95%CI:18.7–41.2);P=0.63].Grade 3 or above adverse events were reported in 28.4%of patients,being similar with oral and infusional FP,and included 10.5%of neutropenia and 2.1%of diarrhoea *** The current analysis demonstrates comparable efficacy and safety profiles of cetuximab in combination with oral and infusional FP in Chinese *** results expand treatment options for Chinese patients and invite revision of existing treatment guidelines to incorporate oral FP-based chemotherapy plus cetuximab.

This study examines the long-term variations of tropical cyclone(TC) frequency and intensity in the South China Sea(SCS) and the vicinity of Hong Kong from 1961 to 2010 based on the best track data of four main weather agencies in the western North Pacific, namely the Hong Kong Observatory, China Meteorological Administration, Regional Specialized Meteorological Center Tokyo and Joint Typhoon Warning Center of the United States. To account for the discrepancy in the best track data between agencies, the maximum sustained wind speeds are standardized to the 10-minute average before data analysis. Moreover, a sensitivity assessment based on three different data scenarios is also conducted to study the uncertainty in trend analysis due to the discrepancy in the datasets from various agencies. The results show that, likely modulated by the El Ni?o Southern Oscillation and the Pacific Decadal Oscillation, there exist strong inter-annual and inter-decadal variations in the TC frequency in the SCS and the vicinity of Hong *** the long-term trend, all dataset/scenario combinations depict a decrease in the TC frequency in the SCS and the vicinity of Hong Kong during the study period, but the trend is not statistically significant at 5% level for most of the datasets. As for the TC intensity, the discrepancy between weather agencies remains very substantial even when the difference in the wind speed averaging period is accounted for. The large differences in the available datasets do not allow for a reliable detection of the long-term trend of the TC intensity in the SCS. The study of the TC impacts on Hong Kong reveals that there is no significant trend on the TC-induced extreme rainfall in Hong Kong. The extreme high winds associated with TCs within 500 km range of Hong Kong have no significant trend at Waglan Island(offshore island) while those of the urban station at Kai Tak have a signifi-cant decreasing trend.
