In this case study,we analyzed the wound-healing process of a patient with a chronic wound who underwent fire needle treatment,and we tracked the coverage of granulation tissue and decrease of slough and exudate.An 85-year-old man had repeated right shoulder and back pain,itching,and skin festering for more than 1.5 years.A fire needle was administered combined with moist dressing once every 5 days to promote wound healing.After six rounds of fire needle treatment,granulation tissue formed over the surface of the wound base,the depth of the wound had become shallow,and the wound area was reduced.No complications occurred during the intervention.Fire needle therapy combined with a moist wound-healing dressing can be an effective alternative approach in managing chronic wounds. 展开更多

MUSIC education in China and the West may differ in approach, but when combined are complementary in outcome. China's music programs excels in training young artists under 18, while the Western focus is on musicians no younger than 18. This explains why so many outstanding Chinese musicians study at, and are welcomed by, Western schools after receiving their initial training in China. 展开更多

"X以上"是一个古老的格式。为了表意的严密,现代汉语中"X以上"格式有了演进,形成了三种新兴的较为定型的模式。第一种模式为"X前后复用式",比如"X或/及X以上";第二种模式为"X后项指代式",比如"X及其以上";第三种模式为"X后项减省式",比如"X及以上"。从纷乱到成型,从增繁到再趋简,从共存到频率有秩,这是上述新兴模式的演进轨迹。本文分别描写三种模式的基本状况,并且对新兴模式的演进轨迹做了解说。文章最后还指出,书面语以口语为基础,但书面语的发展有其特殊需求,并非口语的简单复制。 展开更多

Resource-based cities are the most important players in responding to climate change and achieving low carbon development in China.An analysis of relevant data(such as the energy consumption)showed an inter-city differentiation of CO2 emissions from energy consumption,and suggested an influence of the Industrial Enterprises above Designated Size(IEDS)in resource-based industrial cities at the prefecture level and above in different regions.Then by geographical detector technology,the sizes of each influencing mechanism on CO2 emissions from energy consumption of the IEDS were probed.This analysis showed that significant spatial differences exist for CO2 emissions from energy consumption and revealed several factors which influence the IEDS in resource-based cities.(1)In terms of unit employment,Eastern and Western resource-based cities are above the overall level of all resource-based cities;and only Coal resource-based cities far exceeded the overall level among all of the cities in the analysis.(2)In terms of unit gross industrial output value,the Eastern,Central and Western resources-based cities are all above the overall level for all the cities.Here also,only Coal resource-based cities far exceeded the overall level of all resources-based cities.Economic scale and energy structure are the main factors influencing CO2 emissions from energy consumption of the IEDS in resource-based cities.The factors influencing CO2 emissions in different regions and types of resource-based cities show significant spatial variations,and the degree of influence that any given factor exerts varies among different regions and types of resource-based cities.Therefore,individualized recommendations should be directed to different regions and types of resource-based cities,so that the strategies and measures of industrial low carbon and transformation should vary greatly according to the specific conditions that exist in each city. 展开更多
