OBJECTIVE: To enhance the understanding of identifying personalized pharmacotherapy options in Traditional Chinese Medicine(TCM), and further support the registration of new TCM drugs. METHODS: Generalized Boosted Models and XGBoost were employed to construct a classification model to identify the bad prognosis factors in resistant hypertension(RH) patients. Furthermore, we used association analysis to explore the rules of "symptomsyndrome" and "symptom-herb" for the major influencing factors, in order to summarize prescription pattern and applicable patients of TCM. RESULTS: Patients with major adverse cardiac events mostly have complex symptoms of phlegm, stasis, deficiency and fire intermingled with each other, and finally summarized the human experience of using Chinese herbal medicine to precisely intervene in some symptoms of RH patients on the basis of conventional Western medical treatment. CONCLUSIONS: Machine learning algorithms can make full use of human use experience and evidence to save clinical trial resources and accelerate the development of TCM varieties.

为探究短时间内德玛森小岩鲷(Chindongodemasoni)在模拟捕食刺激下对路标线索的利用能力,以及不同群体规模对群体决策的影响,实验选取喜好集群的德玛森小岩鲷幼鱼为研究对象,考察不同鱼群规模(3、6和9尾),在自然状态及经过短时间对路标和隐蔽场所建立联系后遭遇模拟捕食刺激下做出的群体决策情况。实验设置了1个6臂辐射迷宫为竞技场,包含一条具有路标、挡板和水草作为隐蔽场所的隐蔽场所臂、1条只有挡板的误导臂和4条空白臂。以鱼群在自然状态和应激状态下首次选择臂占比和首次到达各臂的时间等参数作为评估指标。在自然状态下鱼群首次选择不同类型臂的概率是均等的,经过短时间的空间探索后在应激状态下,3种不同群体规模的鱼群首次选择隐蔽场所臂的占比都显著增加(P<0.05),首次到达隐蔽场所臂的时间均显著减少(P<0.05);随着群体规模的增大,在应激状态下首次选择隐蔽场所臂的占比减少(P<0.05),在两种状态下鱼群在隐蔽场停留时间占比均有所减少(P<0.05),这可能是因为随着群体的增大其反捕食策略发生变化。研究表明:德玛森小岩鲷能够在短时间内利用搜集到的路标线索与隐蔽场所建立联系,在遇到捕食刺激时能准确且快速地找到避难场所。并且随着群体规模增大,在模拟捕食刺激下群体的决策准确性呈现下降趋势。

Plastic pollution has become a global environmental issue,posing notable threats to ecosystems and human health. Plastic aging is a continuous dynamic process,during which plastics of various sizes are produced and exist,such as large plastics,microplastics,and nanoplastics. Regardless of the size,plastics continuously fragment and release plastic additives and other soluble products. Moreover,due to the same molecular composition,the aging mechanisms and characteristics of micro and nanoplastics are similar to those of macroplastics. However,the smaller the particle size,the greater the potential harm. To enhance understanding of the environmental effects of plastics,this review focused on the entire dynamic process from the initial form of plastics to their degradation and summarized the aging mechanisms involved,changes in properties,and the products released during this process. These products include macroplastics,micro and nanoplastics,plastic additives,and other soluble substances. The paper also summarized relevant studies and main conclusions on plastic aging experiments,further exploring factors that influence the leaching of plastic additives and the release of micro and nanoplastic particles. Finally,it provided a summary of the environmental hazards that were caused by plastic aging products. © 2025 Science Press. All rights reserved.
