RESUMEN
Traditional anode materials have disadvantages like low specific surface area and poor electrical conductivity. Herein, carbonized Chinese dates (CCD) were synthesized as microbial fuel cells (MFC) anodes. The obtained materials exhibited excellent biocompatibility with fast start-up (within one day) and charge transfer (Rct 4.0 Ω). Their porous structure allows efficient ion transport and microbial community succession, favorable for long-term operation. The biomass analysis shows that CCD anodes can load higher weight of biomass. High-throughput sequencing (16S rRNA) discovered that CCD anode can enrich Geobacter spp., with highest abundance of 73.4%, much higher than carbon felt (CF, 39.2%). Benefit from these properties, the MFC with CCD anodes possess a maximum power density of 12.17 W m-3 (1.62 times of commercial carbon felt). In all, the CCD anode exhibits high performance with low cost and easy fabrication, certificating it a promising candidate for an ideal MFC anode material.

Objective] To analyze the medication experience of Zhong Yi-tang for insomnia by using TCM inheritance support system 1.1ver.[Methods] The prescriptions of Zhong Yi-tang for insomnia were collected and input the data into TCM inheritance support system .The frequency and association rules of drugs were calculated by using data mining methods such as apfiofi algorithm,complex system entropy cluster and unsupervised hierarchical cluster,and medication rule of Zhong Yi-tang for epigastric pain was analyzed.[Results] Based on the analysis of 354 prescriptions, the frequency of each herb and association rules among the herbs were computed. Spine date seed, tuber fleeceflower stem, paeony, red sage root, boxthorn and Chinese Date were highly frequently found, 18 pairs of Chinese medicines based on these and 5 core combinations such as ganmai-dazao decoction were mined out . [Conclusion] Zhong Yi-tang usually used ganmai-dazao decoction, spine date seed, tuber fleeceflower stem and red sage root to cure insomnia. The sweet and moistening Chinese medcine were used to strengthen-spleen-stomach, benefiting ying-blood, and nourishing the heart-blood. Data mining method can be used to analyze old TCM doctors’clinical experience.
