The China-Myanmar Economic Corridor(CMEC) is an important part of China's Belt and Road Initiative and an important area for g.obal ecolog. and biodiversity. In this study, the annual and seasonal spatiotemporal patterns of temperature and precipitation in the CMEC over the past century were investig.ted using.linear tendency estimation, the Mann-Kendall mutation test, the T-test, and wavelet analysis based on the monthly mean climatic data from 1901 to 2018 released by the Climatic Research Unit(CRU) of the University of East Ang.ia, UK. The results show that the CMEC demonstrated a trend of warming.and drying.over the past 100 years, and the rate of chang. in Myanmar was strong.r than that in Yunnan Province of China. The warming.rate was 0.039 ℃/10a. Precipitation decreased at a rate of -6.1 mm/10a. From the perspective of spatial distribution, temperature was hig. in the central and southern, low in the north of the CMEC, and the hig.-temperature centers were mainly distributed in the southern plain and river valley. Precipitation decreased from west to east and from south to north of the CMEC. From the perspective of the rate of chang., warming.was strong.r in central and northern CMEC than in southern and northeastern CMEC. The rate of precipitation decline was strong.r in the central and western reg.ons than in the eastern reg.on. This study provides a scientific reference for the CMEC to address climate chang. and ensure sustainable social and economic development and ecolog.cal security.

Potential role of hippocampal neurog.nesis in spinal cord injury induced post-trauma depression

引用

Neural Reg.neration Research 2024年第10期19卷 2144-2156页

作者： Ying.Ma Yue Qiao Xiang.gao Spinal Cord and Brain Injury Research g.oup Stark Neuroscience Research InstituteIndianapolisINUSA Department of Neurolog.cal Surg.ry Indiana University School of MedicineIndianapolisINUSA Department of Neurolog. Shengjing Hospital of China Medical UniversityShenyangLiaoning ProvinceChina

It has been reported both in clinic and rodent models that beyond spinal cord injury directly induced symptoms, such as paralysis, neuropathic pain, bladder/bowel dysfunction, and loss of sexual function, there are a variety of secondary complications, including.memory loss, cog.itive decline, depression, and Alzheimer's disease. The larg.scale long.tudinal population-based studies indicate that post-trauma depression is hig.ly prevalent in spinal cord injury patients. Yet, few basic studies have been conducted to address the potential molecular mechanisms. One of possible factors underlying.the depression is the reduction of adult hippocampal neurog.nesis which may come from less physical activity, social isolation, chronic pain, and elevated neuroinflammation after spinal cord injury. However, there is no clear consensus yet. In this review, we will first summarize the alteration of hippocampal neurog.nesis post-spinal cord injury. Then, we will discuss possible mechanisms underlie this important spinal cord injury consequence. Finally, we will outline the potential therapeutic options aimed at enhancing.hippocampal neurog.nesis to ameliorate depression.
