未破裂颅内动脉瘤形态学分析被广泛用于动脉瘤破裂的风险评估和术前规划。三维视角较既往的二维视角更能精确体现动脉瘤的形态变化，但人工测量在三维视角下准确度较低且可重复性差，而人工智能在三维视角下的测量更有优势。但是，目前尚缺乏人工智能在三维视角下的动脉瘤形态测量方法。考虑到三维视角下的规范化测量对形态学参数的临床和科研运用具有重要意义，本文提出了一套三维视角下基于人工智能的未破裂颅内动脉瘤形态学指标测量方法，以期推动动脉瘤研究的同质化和临床诊疗的规范化发展。 Abstract: Morphological analysis of unruptured intracranial aneurysms is widely used in risk assessment and surgical design. Compared with the manual measurement in the two-dimensional perspective, the three-dimensional perspective can reflect the morphology changes of aneurysms more accurately. But the manual measurement in the three-dimensional perspective has poor accuracy and repeatability. Therefore, the measurement of artificial intelligence in the three-dimensional perspective has greater advantages than that of manual measurement. However, the method of aneurysm morphological measurement in the three-dimensional perspective based on artificial intelligence has not been proposed. The standardized measurement in the three-dimensional perspective is of great significance to the clinical and research application of morphological parameters. In this paper, a three-dimensional measurement method for unruptured intracranial aneurysms based on artificial intelligence is presented, in order to promote the homogenization of aneurysm research and the standardization of clinical diagnosis and treatment.

In order to study the effects of NaHCO3 stress on the morphological indices and photosynthetic parameters of purple root Eichhornia crassipes, we used purple root E. crassipes as material, treated the adult purple root E. crassipes with different concentrations of the alkaline salt NaHCO3 solution, and determined the morphological indices of purple root E. crassipes, including plant height, root length, root-shoot ratio, biomass, water content, and photosynthetic parameters of purple root E cmssipes, including net photosynthetic rate (Pn), intercellular CO2 concentration (Ci), transpiration rate (Tt) and stomatal conductance (Gs) . The resules were as follows: The pH value of the water solution of purple root E. crassipes at 20 mmol · L-1 NaHCO3 concentration was the most gentle; In low concentration of alkaline salt NaHCO3 solution ( ≤ 40 mmol · L-1 ), compared with CK, the morphological indices of purple root E. crassipes showed an increase or no significant effect, while in high concentration alkaline salt NaHCO3 solution (≥ 60 mmol · L-1), with the increase of NaHCO3 concentration, the morphological indices of purple root E. crassipes decreased significantly, and there was negative correlation with the concentration of NaHCO3; NaHCO3 stress had a significant effect on the photosynthetic parameters of purple root E. crassipes, with the increase of the alkaline salt NaHCO3 concentration and the extension of expermental treatment time, the Pn of purple root E. crassipes showed a continuously decrease trend, and Ci, TT and Gs generally showed a continuously increase trend, and non-stomatal restriction was the main way to restrict photosynthesis in the purple root E. crassipes. Comprehiensive analysis indicates that the purple root E. crassipes has a Certain resistance to NaHCO3 and the purple root E. crassipes can normally survive in water environment with an alkali concentration of no more than 40 mmol · L-1 NaHCO3, and the purple root E. crassipes can improve the pll value of water bodies in the low alkaline salt NaHCO3 concentrations.
