目的:探讨早期胃肠营养对脑外伤昏迷患者氮代谢和胃肠道功能的影响。方法:选择2019年1月—2023年1月常熟市中医院收治的80例脑外伤昏迷患者,按1∶1的比例随机分为对照组和观察组,各40例。对照组接受常规营养支持,观察组在创伤后早期接受特定的胃肠营养支持。对两组氮代谢相关指标、营养指标、胃肠道功能、免疫功能指标及并发症总发生率进行评估。结果:干预7 d后,观察组氮代谢改善更显著,胃排空时间、胃肠道激素水平等胃肠道功能相关指标均优于对照组,IgG、IgA、CD4^(+)T细胞及CD4^(+)/CD8^(+)均高于对照组,差异均有统计学意义(P<0.05)。此外,观察组的并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论:早期胃肠营养支持可以改善脑外伤昏迷患者的氮代谢、胃肠道功能和免疫功能,有助于促进患者的康复,降低并发症的风险。

Emotion recognition in conversation(ERC) has attracted growing attention in recent years as a result of the advancement and implementation of human-computer interface technologies. In this paper,we propose an emotional inertia and contagion-driven dependency modeling approach(EmotionIC) for ERC tasks. Our EmotionIC consists of three main components, i.e., identity masked multi-head attention(IMMHA), dialogue-based gated recurrent unit(DiaGRU), and skip-chain conditional random field(SkipCRF).Compared to previous ERC models, EmotionIC can model a conversation more thoroughly at both the feature-extraction and classification levels. The proposed model attempts to integrate the advantages of attention-and recurrence-based methods at the feature-extraction level. Specifically, IMMHA is applied to capture identity-based global contextual dependencies, while Dia GRU is utilized to extract speaker-and temporal-aware local contextual information. At the classification level, SkipCRF can explicitly mine complex emotional flows from higher-order neighboring utterances in the conversation. Experimental results show that our method can significantly outperform the state-of-the-art models on four benchmark *** ablation studies confirm that our modules can effectively model emotional inertia and contagion.

Retrieval experiment was made for global total column ozone using the first year measurements of Total Ozone Unit (TOU) on board the second generation polar orbiting meteorological satellite of China, FY-3/A. The retrieval results were analyzed and validated by comparison with AURA/OMI, Meteop/GOME-2 global ozone products and ground-based ozone measurement data. The qualititative comparisons over the globe especially over Antarctica and the Tibetan Plateau show that the spatial and temporal distribution characteristics are consistent with OMI and GOME-2 products. The quantitative comparisons with ground-based measurements and AURA/OMI ozone product were made over 74 stations, the TOU total ozone retrieval has a 3% rms relative error compared with AURA/OMI ozone product and 4.2% rms relative error with ground-based measurements. The maximum difference between satellite retrieval and ground-based measurements was found in the Antarctica ozone hole. The TOU global ozone product is operational and distributed to all users.
