Methods: A methodological study was designed with 2 phases. In phase 1, a three-expert panel was invited to evaluate the content validity of SINS-CN, and then its test-retest reliability was examined over a 2-week interval. In phase 2,211 undergraduate nursing students were recruited, and 203 valid responses to the questionnaire were obtained. A principal component analysis with varimax rotation was applied to validate the structure of the instrument. Results: The content validity index(CVI) was 0.89. The correlation coefficient of the test-retest reliability was 0.82 for the overall instrument and 0.70-0.88 for the instrument's sub-dimensions. Based on the 43 items of the instrument, five components were identified and accounted for 60. 28% of the variance with eigenvalues ranging from 1.32 to 10. 18. The factor loadings were 0.42-0.79. The internal consistency reliability of Cronbach's ot was 0.96 for the overall scale and 0.67-0.94 for its sub-dimensions. Conclusion: The study findings indicated that SINS-CN had acceptable psychometric properties in terms of content validity, stability and internal consistency reliability.

Methods: Nursing students were instructed on the basics of active learning prior to the initiation of their clinical experience. The participants were divided into 5groups of nursing students ( n = 56) across three levels (years 2-4) in a public academic institute of a bachelor degree program in Macao. Final clinical evaluation was averaged and compared between groups with and without intervention. Results: These nursing students were given higher appraisals in verbal and written comments than previous students without interventian. The groups with the invention achieved higher clinical assessment and evaluation scores on average than comparable groups without the active learning intervention. One group of sophomore nursing students (year 2) did not receive as high of evaluations as the other groups, receiving an average score of above 80. Conclusions" Nursing students must engage in active learning to demonstrate that they are willing to gain knowledge of theory, nursing skills and communication skills during the clinical practicum.展开更多

The plasmids of over-expressed LRIG3 and the blank plasmid serving as control were transfected into the bladder cancer cell lines, T24, EJ and BIU-87, and the expression levels of LRIG3 mRNA and protein were de- tected by using real-time PCR and Western blotting. The changes in the cell cycle and apoptosis were examined by using flow cytometry. The invasive ability was measured by Transwell assay, and CCK-8 assays were used to measure the proliferation of cells. As compared with the control group, the LRIG3 mRNA and protein expression levels in LRIG3 cDNA-transfected group were raised significantly (P〈0.05). The average number of cells with up-regulated LRIG3 passing through the inserted filter was decreased significantly as compared with the control group (P〈0.05). Up-regulation of LRIG3 also could inhibit proliferation and induce apoptosis of T24, EJ and BIU-87 cells. Except BIU-87, the T24 and EJ cells transfected with LIRG3 eDNA were arrested in G0/G1 phase compared to the control group (P〈0.05). In conclusion, the over-expression of LRIG3 could influence the cell cycle and invasion, in- hibit proliferation and induce apoptosis in the three bladder cancer cell lines.展开更多

Methods: A methodological study design was used. The instrument was translated into Chinese and back-translated into English. A six-expert panel was invited to evaluate the content validity, and a pilot test was subsequently performed on the test-retest stability of the translated instrument. A convenience sampling method was used to recruit 240 nurses from a university teaching hospital in the Mainland of China. In total, 186 valid questionnaires were collected with a 77.5% valid return rate. The validity of the multiple-choice test items (item difficulties and discriminating indices) and internal consistency reli- ability were evaluated. Results: The translated and modified instrument demonstrated acceptable psychometric properties, as follows: (1) the overall content validity index (CVI) was 0.91, (2) the overall test-retest reliability was 0.826, (3) the item difficulty indices were between 0.46 and 0.93, (4) the overall values for discrimination were 0.28-0.55, and (5) the Cronbach's a for the internal consistency were 0.792 for the overall in- strument and 0.426-0.804 for the sub-themes. Conclusions: This study represents the first trial to translate and modify an existing instrument that measures the knowledge of pressure ulcers in a Chinese Mainland sample. The instrument demonstrated acceptable psychometric properties and could be applied in cross-cultural nursing practices, including nursing education, research and practice, to evaluate knowledge about pressure ulcer prevention.展开更多

In particular, the characterization of the urban temperature trend was investigated using the seasonal unit root analysis of monthly mean air temperature data over the period January 1970 to December 2013. The seasonal unit root test makes it possible to determine the stochastic trend of monthly temperatures using an autoregressive model. The test results showed that mean air temperature has increased by 0.169~ C (10 yr) - 1 over the past four decades. The model of monthly temperature obtained from the seasonal unit root analysis was able to explain 95.9% of the variance in the measured monthly data -- much higher than the variance explained by the ordinary least-squares model using annual mean air temperature data and other studies alike. The model accurately predicted monthly mean air temperatures between January 2014 and December 2015 with a root-mean-square percentage error of 4.2%. The correlation between the predicted and the measured monthly mean air temperatures was 0.989. By analyzing the monthly air temperatures recorded at an urban site and a rural site, it was found that the urban heat island effect led to the urban site being on average 0.865~C warmer than the rural site over the past two decades. Besides, the results of correlation analysis showed that the increase in annual mean air temperature was significantly associated with the increase in population, gross domestic product, urban land use, and energy use, with the R2 values ranging from 0.37 to 0.43.展开更多

Difficulties students confronted when facing dying patients challenge the quality of nursing education. A better understanding of students' experiences would enhance teachers' ability in helping students. This study aims to describe available evidence about nursing students' experiences when caring for dying patients and their families.Methods: A review of qualitative studies published between 2005 and 2017 was undertaken using the following databases: MEDLINE, CINAHL, ProQuest Central, ScienceDirect, and CNKI. The keywords included were nursing students, experience, care, end-of-life, and dying. Qualitative Assessment and Review Instrument was used to assess the quality of the studies by two independent reviewers. The data from the studies were analyzed by meta-synthesis.Results: Eighteen English and two Chinese studies were selected in this review. Four themes were emerged:(1) Students with dying patients: students did not have enough ability in symptoms control, comfort supply, and therapeutic communication for dying patients.(2) Students with the patients' families: students advocated more caring for patients' families.(3) Students with the surroundings: professional medical staffs, especially the nursing preceptors, were key roles in constructing a supporting system for students.(4) Students with themselves: nursing students underwent various negative feelings and adopted both negative and positive strategies to cope with such feelings;students experienced professional and personal development during the caring for dying patients.Conclusions: Nursing students' abilities in terminal symptom control, comfort supply, and therapeutic communication should be improved by more theoretic learning and simulation practice. The nursing preceptors were key roles in constructing a supporting system for students and helping them to control the negative emotions when facing dying patients.展开更多

These will spark a revolution in how we approach driving. Cars will no longer need human drivers; they will be connected and exchange information about navigation, road hazards, traffic conditions, and safety. Travelers will be connected more than ever. Today' s car will become tomorrow' s office and the act of driving will become a leisure activity rather than a necessity. The emerging Internet of Vehicle enables application scenarios unimaginable just few years ago. The main challenges are Internet access spectrum scarcity, mobility, intermittent connectivity and scalability. In this article, we discuss the evolution from intelligent vehicle grid to autonomous, internet-conneeted vehicles and vehicular cloud.展开更多

The objectives of this study were to identify the antimicrobial resistance pattern, and determine the prevalence, genotype and clonal relationship of ESBLs in 209 clinical Escherichia coli strains from Macao, China. Methods Antimicrobial susceptibility test was performed to determine the resistance patterns of the isolates using the disk diffusion method with 17 antimicrobial agents. Phenotypic detection was screened and confirmed according to the Clinical and Laboratory Standards Institute. Genotypic characterization was detected by isoelectric focusing analysis, polymerase chain reaction and sequencing. The clonal relationship between the different ESBL isolates was studied by pulsed-field gel electrophoresis (PFGE). Results Imipenem and meropenem exhibited 100% susceptible among 209 strains. Overall, 82.3%, 67.3%, 52.9%, 51.2% and 51.0% of the isolates displayed resistance to ampicillin, tetracylcline, ciprofloxacin, sulfamethoxazole trimethoprin and gentamycin. The prevalence rate of ESBLs was 30.1%. Antibiotic resistances were found to be significantly higher among the ESBL producing group compared to non-ESBL producing group. We detected CTX-M-14 to be the major genotypic characterization of ESBLs (76.2%). Two strains showed indistinguishable patterns by PFGE. Conclusions The prevalence of antimicrobial resistance is alarming high in Macao. Antimicrobial resistance is significantly higher among the ESBL producing group. This study documented CTX-M-14 as the predominant ESBL type. Although indistinguishable pattern was found between two strains, it was too small to decide whether any of the investigated strains was epidemic. Our findings may be also pertinent for other geographic areas undergoing similar travel characteristics to understand the corresponding effects on bacterial populations.展开更多

文摘Unmanned Aerial Vehicles(UAVs)acting as aerial users to access the cellular network form a promising solution to guarantee its safe and efficient operations via the high-quality communication.Due to the flexible mobility of UAVs and the coverage range limits of ground base station(GBS),the signalto-noise ratio(SNR)of the communication link between UAVs and GBS will fluctuate.It is an important requirement to maintain the UAV’s cellular connection to meet a certain SNR requirement during the mission for UAV flying from take off to landing.In this paper,we study an efficient trajectory planning method that can minimize a cellular-connected UAV’s mission completion time under the connectivity requirement.The conventional method to tackle this problem adopts graph theory or a dynamic programming method to optimize the trajectory,which generally incurs high computational complexities.Moreover,there is a nonnegligible performance gap compared to the optimal solution.To this end,we propose an iterative trajectory optimizing algorithm based on geometric planning.Firstly,we apply graph theory to obtain all the possible UAV-GBS association sequences and select the candidate association sequences based on the topological relationship among UAV and GBSs.Next,adopting the triangle inequality property,an iterative handover location design is proposed to determine the shortest flight trajectory with fast convergence and low computation complexity.Then,the best flight trajectory can be obtained by comparing all the candidate trajectories.Lastly,we revealed the tradeoff between mission completion time and flight energy consumption.Numerical results validate that our proposed solution can obtain the effectiveness with set accuracy and outperform against the benchmark schemes with affordable computation time.
文摘The purpose of this study was to investigate the impact of leucine-rich repeats and immu- noglobulin-like domains 3 (LRIG3) on the biological features of bladder cancer cell lines. The plasmids of over-expressed LRIG3 and the blank plasmid serving as control were transfected into the bladder cancer cell lines, T24, EJ and BIU-87, and the expression levels of LRIG3 mRNA and protein were de- tected by using real-time PCR and Western blotting. The changes in the cell cycle and apoptosis were examined by using flow cytometry. The invasive ability was measured by Transwell assay, and CCK-8 assays were used to measure the proliferation of cells. As compared with the control group, the LRIG3 mRNA and protein expression levels in LRIG3 cDNA-transfected group were raised significantly (P〈0.05). The average number of cells with up-regulated LRIG3 passing through the inserted filter was decreased significantly as compared with the control group (P〈0.05). Up-regulation of LRIG3 also could inhibit proliferation and induce apoptosis of T24, EJ and BIU-87 cells. Except BIU-87, the T24 and EJ cells transfected with LIRG3 eDNA were arrested in G0/G1 phase compared to the control group (P〈0.05). In conclusion, the over-expression of LRIG3 could influence the cell cycle and invasion, in- hibit proliferation and induce apoptosis in the three bladder cancer cell lines.

文摘Objective: This study sought to translate, modify and validate an instrument developed by Beckman and colleagues to assess the knowledge of clinical nurses regarding pressure ulcers. Methods: A methodological study design was used. The instrument was translated into Chinese and back-translated into English. A six-expert panel was invited to evaluate the content validity, and a pilot test was subsequently performed on the test-retest stability of the translated instrument. A convenience sampling method was used to recruit 240 nurses from a university teaching hospital in the Mainland of China. In total, 186 valid questionnaires were collected with a 77.5% valid return rate. The validity of the multiple-choice test items (item difficulties and discriminating indices) and internal consistency reli- ability were evaluated. Results: The translated and modified instrument demonstrated acceptable psychometric properties, as follows: (1) the overall content validity index (CVI) was 0.91, (2) the overall test-retest reliability was 0.826, (3) the item difficulty indices were between 0.46 and 0.93, (4) the overall values for discrimination were 0.28-0.55, and (5) the Cronbach's a for the internal consistency were 0.792 for the overall in- strument and 0.426-0.804 for the sub-themes. Conclusions: This study represents the first trial to translate and modify an existing instrument that measures the knowledge of pressure ulcers in a Chinese Mainland sample. The instrument demonstrated acceptable psychometric properties and could be applied in cross-cultural nursing practices, including nursing education, research and practice, to evaluate knowledge about pressure ulcer prevention.
文摘This paper explores urban temperature in Hong Kong using long-term time series. In particular, the characterization of the urban temperature trend was investigated using the seasonal unit root analysis of monthly mean air temperature data over the period January 1970 to December 2013. The seasonal unit root test makes it possible to determine the stochastic trend of monthly temperatures using an autoregressive model. The test results showed that mean air temperature has increased by 0.169~ C (10 yr) - 1 over the past four decades. The model of monthly temperature obtained from the seasonal unit root analysis was able to explain 95.9% of the variance in the measured monthly data -- much higher than the variance explained by the ordinary least-squares model using annual mean air temperature data and other studies alike. The model accurately predicted monthly mean air temperatures between January 2014 and December 2015 with a root-mean-square percentage error of 4.2%. The correlation between the predicted and the measured monthly mean air temperatures was 0.989. By analyzing the monthly air temperatures recorded at an urban site and a rural site, it was found that the urban heat island effect led to the urban site being on average 0.865~C warmer than the rural site over the past two decades. Besides, the results of correlation analysis showed that the increase in annual mean air temperature was significantly associated with the increase in population, gross domestic product, urban land use, and energy use, with the R2 values ranging from 0.37 to 0.43.

文摘Objective: Nurses play important roles in caring for dying patients and their families. Difficulties students confronted when facing dying patients challenge the quality of nursing education. A better understanding of students' experiences would enhance teachers' ability in helping students. This study aims to describe available evidence about nursing students' experiences when caring for dying patients and their families.Methods: A review of qualitative studies published between 2005 and 2017 was undertaken using the following databases: MEDLINE, CINAHL, ProQuest Central, ScienceDirect, and CNKI. The keywords included were nursing students, experience, care, end-of-life, and dying. Qualitative Assessment and Review Instrument was used to assess the quality of the studies by two independent reviewers. The data from the studies were analyzed by meta-synthesis.Results: Eighteen English and two Chinese studies were selected in this review. Four themes were emerged:(1) Students with dying patients: students did not have enough ability in symptoms control, comfort supply, and therapeutic communication for dying patients.(2) Students with the patients' families: students advocated more caring for patients' families.(3) Students with the surroundings: professional medical staffs, especially the nursing preceptors, were key roles in constructing a supporting system for students.(4) Students with themselves: nursing students underwent various negative feelings and adopted both negative and positive strategies to cope with such feelings;students experienced professional and personal development during the caring for dying patients.Conclusions: Nursing students' abilities in terminal symptom control, comfort supply, and therapeutic communication should be improved by more theoretic learning and simulation practice. The nursing preceptors were key roles in constructing a supporting system for students and helping them to control the negative emotions when facing dying patients.

文摘The National Highway Traffic Safety Administration in the US and the European Commission are drafting a regulatory framework that will make the goal of connected vehicles possible by 2020, Control, embedded systems, and communication technologies have devel- oped over the past 10 plus years and are approaching maturity. These will spark a revolution in how we approach driving. Cars will no longer need human drivers; they will be connected and exchange information about navigation, road hazards, traffic conditions, and safety. Travelers will be connected more than ever. Today' s car will become tomorrow' s office and the act of driving will become a leisure activity rather than a necessity. The emerging Internet of Vehicle enables application scenarios unimaginable just few years ago. The main challenges are Internet access spectrum scarcity, mobility, intermittent connectivity and scalability. In this article, we discuss the evolution from intelligent vehicle grid to autonomous, internet-conneeted vehicles and vehicular cloud.

文摘Background The rise of the production of CTX-M class extended spectrum β-lactamases (ESBLs) has been well documented in traveling countries but no data are found for Macao, an international travel city. The objectives of this study were to identify the antimicrobial resistance pattern, and determine the prevalence, genotype and clonal relationship of ESBLs in 209 clinical Escherichia coli strains from Macao, China. Methods Antimicrobial susceptibility test was performed to determine the resistance patterns of the isolates using the disk diffusion method with 17 antimicrobial agents. Phenotypic detection was screened and confirmed according to the Clinical and Laboratory Standards Institute. Genotypic characterization was detected by isoelectric focusing analysis, polymerase chain reaction and sequencing. The clonal relationship between the different ESBL isolates was studied by pulsed-field gel electrophoresis (PFGE). Results Imipenem and meropenem exhibited 100% susceptible among 209 strains. Overall, 82.3%, 67.3%, 52.9%, 51.2% and 51.0% of the isolates displayed resistance to ampicillin, tetracylcline, ciprofloxacin, sulfamethoxazole trimethoprin and gentamycin. The prevalence rate of ESBLs was 30.1%. Antibiotic resistances were found to be significantly higher among the ESBL producing group compared to non-ESBL producing group. We detected CTX-M-14 to be the major genotypic characterization of ESBLs (76.2%). Two strains showed indistinguishable patterns by PFGE. Conclusions The prevalence of antimicrobial resistance is alarming high in Macao. Antimicrobial resistance is significantly higher among the ESBL producing group. This study documented CTX-M-14 as the predominant ESBL type. Although indistinguishable pattern was found between two strains, it was too small to decide whether any of the investigated strains was epidemic. Our findings may be also pertinent for other geographic areas undergoing similar travel characteristics to understand the corresponding effects on bacterial populations.
