This concept not only helps patients speed up postoperative recovery, reduce the incidence of related complications and shorten hospital stays, but also has been proved to be effective and safe in the perioperative application of gastric cancer. This article reviews the clinical application and research progress of enhanced recovery after surgery in the perioperative period of advanced gastric cancer in the elderly.展开更多

The vaginal flora is in a state of balance, and the microorganisms coexist and are interdependent to maintain the vaginal micro-ecological balance, which is a kind of dynamic balance influenced by endogenous and exogenous factors. Vaginal infections are traditionally treated by killing microbes in the vagina. Given the extensive study of the internal vaginal environment, people become gradually aware of the significance of maintaining the vaginal micro-ecological balance rather than blindly using antimicrobial agents. The balance in the vaginal internal environment is disrupted during the gestation period as the secretion of progesterone increases. The imbalanced vaginal micro-ecological environment may lead to vaginal infectious diseases. This paper provides a review of the relationship between the vaginal microecology and infectious diseases during gestation period.展开更多
作物生殖生长期长度与作物产量和品质密切相关。为深入探究作物生殖生长期长度(reproductive growth period lengths,RGLs)对气候变化和技术进步的响应,基于1981—2010年长江中下游地区单季稻生殖生长期和气象数据,量化不同RGLs (孕穗...作物生殖生长期长度与作物产量和品质密切相关。为深入探究作物生殖生长期长度(reproductive growth period lengths,RGLs)对气候变化和技术进步的响应,基于1981—2010年长江中下游地区单季稻生殖生长期和气象数据,量化不同RGLs (孕穗期—抽穗期(booting to heading,BDHD)、抽穗期—乳熟期(heading to milking,HDMS)、乳熟期—成熟期(milking to maturity,MSMD)和孕穗期—成熟期(booting to maturity,BDMD))对平均温度(mean temperature,TEM)、累积降水量(cumulative precipitation,PRE)和累积日照时数(cumulative sunshine duration,SSD)的敏感性,并分离气候变化和技术进步对不同RGLs的影响。结果表明,1981—2010年长江中下游地区单季稻BDMD呈延长趋势(0.24d a^(–1)),其中,HDMS延长趋势最明显(0.16 d a^(–1))。气候因子中高温和寡照不利于单季稻不同RGLs延长,其中,TEM对BDHD、HDMS和MSMD变化趋势的平均相对贡献分别为–50.0%、–50.7%和–21.9%,SSD对BDHD、HDMS和MSMD变化趋势的平均相对贡献分别为–47.2%、–48.7%和–67.6%。技术进步弥补了气候变化对不同RGLs变化趋势的不利影响。研究表明,技术进步可能是当前单季稻稳产高产和趋利避害的主要手段,未来可以采用较长生殖生长期和耐热性品种来适应持续的气候变化。展开更多
