海南渔民曾经使用过的30余部具有个性化的《更路簿》,2011年入选国家级非遗代表性项目名录。通过梳理《海南针经》和《南海天书》以及相关的史实,对《更路簿》之“更长”的论述,囿于其源头的趋同性、“更长”设定海洋环境的一致性、船体体量与功能的类型化、航海技术的同质化、实际停靠岛礁位置的差异性,甚至近代东南亚十二刻表的使用、罗盘设计的变化、航海的便易性、岛礁形状的变动性等,我们认为现有的各种《更路簿》之“更长”,作为时间单位,为“一昼夜十二更”;作为里程单位,为“一更40里”。当然,除去“时间单位”和“里程单位”的解读,“更”还有其他内涵的解读,如“改变”之义等。

本文研究了添加Na Cl、CaCl_2及FeCl_3对壳聚糖/果胶/阿拉伯胶聚电解质复合物(PEC)溶液的浊度、膜的溶胀度、接触角和机械性能等的影响,并通过红外光谱分析和扫描电镜观察,探讨了离子对PEC静电复合及膜结构的影响。结果表明:在0~60 mmol/L浓度范围内,PEC溶液浊度随离子浓度的增大呈现先升高后降低的趋势;离子种类及浓度对PEC膜的溶胀度影响趋势不同,添加50 mmol/L FeCl_3的PEC膜溶胀度显著提高;离子种类及浓度对PEC膜接触角的影响趋势不同;离子添加可以显著提高PEC膜的拉伸强度,降低断裂伸长率,添加40 mmol/L FeCl_3的PEC膜具有最高的拉伸强度;红外光谱分析发现,离子添加不影响壳聚糖和果胶、阿拉伯胶之间的静电复合方式;扫描电镜观察发现添加NaCl、CaCl_2的PEC膜表面相对光滑,而添加FeCl_3形成的膜表面凹凸不平,较粗糙。

目的探讨清胰利胆颗粒联合埃索美拉唑对老年急性胰腺炎患者炎性介质和肠黏膜屏障功能的影响。方法选取2018年1月—2019年12月永康市第一人民医院收治的老年急性胰腺炎患者60例,采用随机数字表法分为观察组和对照组,每组30例。观察组给予清胰利胆颗粒联合埃索美拉唑治疗,对照组给予埃索美拉唑治疗。两组疗程均7 d。比较两组腹痛和腹胀缓解时间;治疗前与治疗7 d炎性介质[白细胞介素-6(IL-6)、超敏C反应蛋白(hs-CRP)、肿瘤坏死因子-α(TNF-α)]和肠黏膜屏障功能[二胺氧化酶(DAO)、内毒素和D-乳酸]的变化。结果观察组腹痛和腹胀缓解时间均短于对照组(P <0.05)。观察组治疗前后IL-6、hs-CRP、TNF-α的差值大于对照组(P <0.05)。观察组治疗前后DAO、内毒素、D-乳酸的差值大于对照组(P <0.05)。结论清胰利胆颗粒联合埃索美拉唑可减轻老年急性胰腺炎患者炎症反应,改善患者肠黏膜屏障功能。
