琼胶酶在多糖降解应用中的作用日益重要,而从海洋微生物中筛选琼胶酶高产菌株成为一个重要途径。本研究从养殖的杂色鲍体内分离到一株高产琼胶酶的菌株MA-B22。该菌为革兰氏阴性菌,经16S rRNA序列鉴定表明,与Tamlana agarivorans ***.具有99%同源性,因此初步定为Tamlana sp.。在2216E培养基中该菌株在培养时间60h,温度25℃,起始pH为6.0条件下产酶活性最高。基于上述培养条件,通过单因素和正交实验确定了培养基的最佳基本组成:氮源为牛肉膏(其最适浓度为6.0‰),碳源为琼脂(其最适浓度为2.5‰),配制培养基的人工海水的最适盐度为25。经培养条件优化后,该菌胞外琼胶酶活力可达1021.79U/mL,较优化前提高8.82倍。实验首次对Tamlana sp.属的琼胶酶活性进行确定并优化其产酶条件,为构建琼胶酶高产工程菌株提供了基础,并可能为今后鲍养殖提供潜在的益生菌。

Large language models (LLMs) such as ChatGPT, Claude, Llama, and Qwen are emerging as transformative technologies for the diagnosis and treatment of various diseases. With their exceptional long-context reasoning capabilities, LLMs are proficient in clinically relevant tasks, particularly in medical text analysis and interactive dialogue. They can enhance diagnostic accuracy by processing vast amounts of patient data and medical literature and have demonstrated their utility in diagnosing common diseases and facilitating the identification of rare diseases by recognizing subtle patterns in symptoms and test results. Building on their image-recognition abilities, multimodal LLMs (MLLMs) show promising potential for diagnosis based on radiography, chest computed tomography (CT), electrocardiography (ECG), and common pathological images. These models can also assist in treatment planning by suggesting evidence-based interventions and improving clinical decision support systems through integrated analysis of patient records. Despite these promising developments, significant challenges persist regarding the use of LLMs in medicine, including concerns regarding algorithmic bias, the potential for hallucinations, and the need for rigorous clinical validation. Ethical considerations also underscore the importance of maintaining the function of supervision in clinical practice. This paper highlights the rapid advancements in research on the diagnostic and therapeutic applications of LLMs across different medical disciplines and emphasizes the importance of policymaking, ethical supervision, and multidisciplinary collaboration in promoting more effective and safer clinical applications of LLMs. Future directions include the integration of proprietary clinical knowledge, the investigation of open-source and customized models, and the evaluation of real-time effects in clinical diagnosis and treatment practices.

基于政策工具和政策要素的二维分析框架,运用内容分析法深度剖析了17份《乡村产业振兴带头人培育“头雁”项目实施方案》。研究发现,从政策工具维度看,命令性工具使用充分,能力建设工具和激励性工具使用尚可,劝告工具与系统变革工具使用较少;从政策要素维度看,培育对象和培育支持成为关注重点,对培育机构、培育保障与培育方式的规定适中,但是培育内容相对被忽略,政策内容要素特性与政策工具配置的逻辑关系初步显现。为完善实施方案,建议优化政策工具配置结构,发挥政策工具协同效应;合理分配政策要素,创新培育内容要素;聚焦培育对象自身实际,适配政策工具与政策内容。
