Objective To investigate the knowledge and attitude towards palliative care among emergency care nurses, and analyze its influencing factors. Methods A questionnaires were conducted among 415 emergency care nurses from tertiary hospitals in Hubei province by using a general information questionnaire, the Hospice Knowledge Quiz for Nurses and the Frommelt Attitudes Toward Care of the Dying Scale Form B (FATCOD-B). Multiple linear step regression was used to analyze the influencing factors. Results The total scores of knowledge and attitude towards palliative care were (12. 44±3. 83) and (97. 35±9. 07), respectively. Sex, professional titles, whether had interactions with a dying patient or not and palliative care training were main factors influencing nurses’ palliative care knowledge. Education level, professional titles and palliative care training were main factors influencing attitude towards palliative care. Conclusion Emergency care nurses had a middle level of knowledge and attitude towards palliative care. More palliative care training including theory and practice should be developed, and nurses with low education level and professional title need to be trained more.

This paper measured the evolution and wave data of the nourished beach, estimated the contributions of erosion amount and effective wave height to beach erosion by taking the West Beach of Beidaihe as an example. The results show that the beach has an overall erosion trend after the nourishment, with the maximum erosion height of 1.7 m. The cumulative influence of the wave height on the beach erosion is an exponential distribution. Although large waves with lower recurrence frequencies (significant wave height>0.6 m) can cause greater beach erosion, their cumulative contribution to the total beach erosion is only about 25%, while the contribution of regular waves with heights of 0.3 m to 0.6 m can reach 75%. This study can provide reference for maintaining the quality of artificial beach, and beach evolution prediction after artificial nourishment. [ABSTRACT FROM AUTHOR]

Objective To observe the curative effects of pulmonary rehabilitation with traditional Chinese medicine（TCM） on chronic obstructive pulmonary disease （COPD） during stable period. Methods A total of 126 patients with COPD during stable period who were admitted to the hospital from February 2017 to November 2018 were enrolled in the study. They were divided into the control group （routine western medicine with routine rehabilitation exercise） and the observation group（TCM pulmonary rehabilitation based on the control group） by randomnumber table method，63 cases in each group. The clinical curative effects， scores of Modified Medical Research Council Scale （mMRC） and TCM syndromes， pulmonary function forced expiratory volume in 1s （FEV1）， forced vital capacity（FVC） and maximum ventilatory volume （MVV） as percentages of predicted value and exercise endurance（6 min walking distance） were compared between the two groups. Results The total response rate of the observation group was significantly higher than that of the control group （90.48% vs76.19%） （P < 0.05） . After treatment， mMRC score and TCM syndrome scores of both groups were significantly decreased， while FEV1%， FVC%， MVV% and 6min walking distance were significantly increased. The mMRC score and TCM syndrome scores in the observation group were significantly lower than those in the control group， while FEV1%，FVC%and MVV%were significantly higher than those in the control group. At 1 month， 3 months and 5 months after treatment， 6 min walking distance in the observation group was significantly larger than that in the control group （P < 0.05） . Conclusion The curative effects of TCMpulmonary rehabilitation are obvious on COPD patients during stable period， which can effectively improve TCM syndromes， respiratory function and exercise endurance.

In order to study the compaction characteristics and particles size distribution of saturated broken rock of continuous gradation，an experimental study was conducted on saturated broken rock which satisfies the Talbol distribution by using self-made equipment and MTS816.03 rock mechanics test system. The influences of n on the secant modulus，the tangent modulus，the porosity，the bulking factor and the compactness were analyzed. The variation laws of distribution coefficient r with Talbol index and axial stress were investigated. The stress-strain relationship of broken rocks was established，which can reflect the variation of particle size distribution. The results show that the secant modulus，the tangent modulus，the porosity，the bulking factor and the compactness of rock samples were negatively related with the Talbol index n in the bearing process of broken rock samples. The distribution coefficient r decreased when axial stress increased. And the distribution coefficient r tended to increase with n，when the axial stress was less than 50% of the uniaxial compressive strength.When the axial stress was more than 50% of the uniaxial compressive strength，the relationship between distribution coefficient r of broken rock samples and n fluctuated. The distribution coefficient r of different n tended to be uniform with the axial stress exceeded 90% of the uniaxial compressive strength. [ABSTRACT FROM AUTHOR]

Lateral confined compression tests for saturated crushed limestone were conducted to study the evolution of the microstructure in crushed rock masses.Micro-CT system was used to observe the microstructure of the samples. Based on the average particle size，the particle crushing state of the saturated crushed limestone under compaction was obtained quantitatively，and the relationship between porosity and average particle size was analyzed. Using image technology，the evolution of the particle shapes was studied quantitatively. The experimental results indicate that during compaction，particle crushing is pervasive，the pores in samples are compressed and filled with fine particles，and the connectivity between pores become worse. The initial gradation influences the porosity of samples. Under same axial stress，the porosity increases with an increase in Talbot exponent. The relationship between the porosity and the average particle size is linear，and the porosity can be used to describe the crushing state of the samples quantitatively. With the increase of axial stress，the circularity of the particles decreases monotonously，the shapes of the particles are more regular，the relationship between circularity and axial stress can be fitted by an exponential function. The study is helpful for a better understanding of deformation mechanism of crushed rock mass. [ABSTRACT FROM AUTHOR]
