Analgesia is an important link in the treatment of severe patients after neurosurgery and plays a vital role in improving the prognosis of the patients.Understanding the status quo and influencing fac-tors of pain in severe patients after neurosurgery helps to predict the occurrence of pain,which is crucial for determining the new pain assessment methods and auxiliary analgesic methods and developing novel analgesic drugs.This paper reviews the pain status,pain evaluation and analgesic methods of severe patients after neuro-surgery in recent years so as to understand the pain management current status of the patients with severe neurological conditions and provide reference for the medical staff to implement the analgesic programs.

Photosynthesis in plants directly affects the synthesis and accumulation of organic matter, which directly influences crop yield. RNA-binding proteins (RBPs) are involved in the regulation of a variety of physiological functions in plants, while the functions of RBPs in photosynthesis have not been clearly elucidated. To investigate the effect of a glycine-rich RNA-binding protein (SlRBP1) in tomato on plant photosynthesis, a stably inherited SlRBP1 silenced plant in Alisa Craig was obtained by plant tissue culture using artificial small RNA interference. It turns out that the size of the tomato fruit was reduced and leaves significantly turned yellow. Chlorophyll(Chl) content measurement, Chl fluorescence imaging and chloroplast transmission electron microscopy revealed that the chloroplast morphology and structure of the leaves of tomato amiR-SlRBP1 silenced plants were disrupted, and the chlorophyll content was significantly reduced. Measurement of photosynthesis rate of wild-type and amiR-SlRBP1 silenced plants in the same period demonstrated that the photosynthetic rate of these plants was significantly reduced, and analysis of RNA-seq data indicated that silencing of SlRBP1 significantly reduced the expression of photosynthesis-related genes, such as PsaE, PsaL, and PsbY, and affected the yield of tomato fruits through photosynthesis.
