Quantitative detection of serum sTim-3, CEA, CA19-9 in 90 patients after the CRC surgery (52 postoperative recurrence and 38 no-postoperative recurrence), 21 patients with colorectal benign tumors, and 67 healthy controls. To analyze the clinical diagnostic value of combined detection of sTim-3 with CEA or CA19-9 to test whether patients have recurrence after CRC surgery.Results: The sTim-3 (15.94± 11.24ng/mL) in patients after CRC surgery was significantly higher than in healthy controls (8.95± 3.34ng/mL) and colorectal benign tumors (8.39± 2.28ng/mL) (P < 0.05), and sTim-3 (20.33± 13.04ng/mL) in CRC postoperative recurrent group was significantly higher than in the group without recurrence after CRC surgery (9.94± 2.36ng/mL) (P < 0.05). In terms of detecting postoperative recurrence after CRC surgery, combined detection of sTim-3 and CEA (AUC: 0.819, sensitivity: 80.77%, specificity: 65.79%), sTim-3 and CA19-9 test (AUC: 0.813, sensitivity: 69.23%, specificity: 97.30%) was significantly better than the CEA single test (AUC: 0.547, sensitivity: 63.16%, specificity: 48.08%) and CA19-9 single test (AUC: 0.675 sensitivity: 65.38%, specificity: 67.57%), Delong test P < 0.05.Conclusion: The efficacy of CEA and CA19-9 single test was not optimal, and the combination of sTim-3 in serum could significantly improve the sensitivity and specificity of detecting patient recurrence after CRC surgery.Keywords: serum tumor markers, Tim-3, time-resolved fluorescence immunoassay, colorectal cancer recurrence

Choristoneura metasequoiacola Liu, 1983 is an important caterpillar species that specifically infests the leaves and branches of Metasequoia glyptostroboides Hu & W. C. Cheng 1948 with short larval infestations, long-term dormancy, and has a limited distribution in Lichuan, Hubei, China. The complete mitochondria genome of C. metasequoiacola was determined by using Illumina NovaSeq, and analyzed based on previously annotated sibling species. In total, we obtained mitochondria genome with 15,128 bp in length, circular in shape with a double-stranded closed ring structure, including 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and an AT-rich region. Of which the nucleotide composition was highly A + T biased, accounting for 81.98% of the whole mitogenome. Thirteen protein-coding genes (PCGs) were 11,142 bp; Twenty-two tRNA genes and AT-rich region were 1,472 and 199 bp, respectively. Phylogenetically, the relationship between Choristoneura spp. (containing C. metasequoiacola) and Adoxophyes spp. was closer than any other two genera from Tortricidae, and the relationship between C. metasequoiacola and C.murinana was the closest among nine sibling species from that genus, which helps to explain species evolution within the family Tortricidae.

采用现代教学手段提高教学效果是目前世界汉语教学的动向之一。由联邦德国石一菏州教育部资助，吕贝克应用科学大学、上海交通大学和上海电视大学联合进行的研究开发项目 “多媒体汉语教学系统“ 乃是在此方向上的一次探索。 除了教材以外，多媒体语言教学系统必须为学习者提供一个完整的仿真语言环境，因此本文的核心是介绍这个语言环境的构筑。文中首先简单介绍了课题目标，进而提出该系统为实现这一目标所必须满足的几项具体要求，其中包括如何使不具备电脑知识的用户能方便地使用本系统。文中着重介绍了本系统用户界面、课程导向系统以及智能词汇训练器的设计。此外，还对系统个性化问题，即如何根据用户需要及学习进程调整系统的适配性，及其在本系统中的实现，作了探讨。对实现过程中遇到的技术问题本文也做了简短的介绍。 最后，本文分析了多媒体语言教学系统的优点和局限之处，指出多媒体系统并不能完全取代教师的职能，也不适合用作 “泛读“ 材科。, CHUN - Chinesischunterricht, Bd. 18 (2003): CHUN - Chinesischunterricht
