为了解青岛沿岸潮间带贝类优势种、群落结构等资源状况,本研究分别于2022年5月(春季)和2022年10月(秋季)对青岛沿海基岩海岸、砂质海岸、粉砂淤泥质海岸以及砂质和基岩混合海岸类型的8个典型站位的潮间带贝类资源进行调查,比较、分析了各站位贝类物种组成、优势度和香农–威纳多样性指数、丰富度指数、均匀度指数等群落结构参数,并采用相似性系数聚类和非度量多维排序方法进行群落聚类分析。结果显示,青岛沿海潮间带共鉴定出贝类40种,沧口发现的贝类物种数最多,达到18种,金口最少,仅发现6种;各调查站位的优势种组成存在差异,且同一站位贝类优势种的种类和优势度随季节的变化而不同,春季优势种主要是短滨螺(Littorina brevicula)、砂海螂(Mya arenaria)和矮拟帽贝(Patelloida pygmaea)等,秋季优势种主要是长牡蛎(Crassostrea gigas)、凸壳肌蛤(Musculista senhousia)和菲律宾蛤仔(Ruditapes philippinarum)等;春季和秋季的多样性指数范围分别为0.85~1.84和0.66~2.00,丰富度指数分别为0.86~1.97和0.62~2.96,均匀度指数分别为0.41~0.84和0.31~0.98,多样性指数和丰富度最高的3个站位为前桃园、鳌山卫和沧口;春秋两季各站位群落聚类结果有所不同,红石崖和金口始终分别为单独一支,沧口和王哥庄始终聚为一类,前桃园和鳌山卫始终聚为一类。研究发现,底质类型对青岛潮间带贝类组成和群落结构特征具有较大影响。本研究查明了青岛不同底质潮间带的贝类资源状况,为青岛潮间带贝类资源的开发、保护和生态修复提供了基础资料。

Objective： To observe the clinical efficacy difference between electroacupuncture at Bǎihui（百会GV 20）and Yintáng（印堂EX-HN 3） and oral administration of sertraline hydrochloride for treatment of postschizophrenic ***： Sixty patients with post-schizophrenic depression were randomly divided into electroacupuncture group and western medicine group in the proportion of 1：1, with 30 patients in each group. The patients in the two groups were all given antipsychotics as the basic treatment. Electroacupuncture at GV 20 and EX-HN 3 was performed additionally in electroacupuncture group with 30 min/time and once every other day. The treatment was given for 3 times a week, lasting for 6 weeks. Oral administration of sertraline hydrochloride was given in western medicine group additionally for once a day, lasting for6 weeks. The comprehensive conditions of patients in the two groups were evaluated before and after treatment by adopting Global Assessment Scale（GAS）. The degree of depression of patients in the two groups was assessed before treatment, after treatment for 1 week, 2 weeks and 4 weeks, after treatment as well as during follow-up visit by adopting Hamilton Depression Scale-17（HAMD-17）.Results： GAS： GAS scores of the patients in the two groups after treatment were higher than those before treatment（both P〈0.05）, but the difference of GAS scores of the patients in the two groups after treatment was not statistically significant. HAMD-17： The HAMD-17 scores of patients in electroacupuncture group reduced gradually in the six time points of before treatment, after treatment for 1 week, 2 weeks and 4 weeks, after treatment as well as during follow-up visit, and the differences of scores between the two adjacent time points were statistically significant（all P〈0.05）. The HAMD-17 scores of patients in western medicine group reduced gradually in the 6 time points, and the differences of scores between the two adjacent time points among after treatment for 2 week

为了研究甘油葡萄糖苷磷酸合成酶(GgpS)在集胞藻PCC 803甘油葡萄糖苷和甘油合成中的作用,本研究在前期获得高产甘油葡萄糖苷藻株的基础上分别过量表达来自于集胞藻PCC 6803自身和聚球藻PCC7002的甘油葡萄糖苷磷酸合成酶基因ggpS,并测定了在不同浓度NaCl胁迫时突变藻株的甘油葡萄糖苷和甘油积累量。结果发现获得的突变株甘油葡萄糖苷合成没有提高,但是甘油合成显著增强。此外,当培养基NaCl浓度从600 mmol/L提高到900 mmol/L时,集胞藻PCC 6803自身ggpS过表达藻株的甘油合成进一步提高75%。这些结果显示了GgpS在将碳代谢流导入集胞藻甘油合成途径中的作用。研究成果也为进一步通过基因工程改造提高集胞藻甘油葡萄糖苷和甘油合成效率奠定了基础。

外来物种是一把“双刃剑”,对本土生态环境和社会经济产生重要影响,准确评估外来物种的营养价值是发挥其经济效益的重要环节。作为近年来侵入我国东南沿海的外来物种,斑纹小贻贝(Mytella strigata)一方面威胁着本地种翡翠股贻贝的生存,另一方面在海南、福建等地区已作为海产品被售卖和食用。在此背景下,本研究依据国家食品安全检测相关标准,对斑纹小贻贝软体部常规营养指标进行测定,分析与评估斑纹小贻贝的营养价值。结果显示:斑纹小贻贝软体部水分、灰分、粗蛋白和粗脂肪的含量(湿重)分别占83.20%、2.00%、12.09%和0.60%;共检测出16种氨基酸,占粗蛋白总量的84.53%,其中7种为必需氨基酸,占氨基酸总量的35.23%,必需氨基酸指数EAAI评分为76.24分,第一限制性氨基酸是半胱氨酸+蛋氨酸;检测出18种脂肪酸,包括7种饱和脂肪酸,占43.71%,4种单不饱和脂肪酸,占11.05%,7种多不饱和脂肪酸,占45.27%,DHA和EPA分别为脂肪酸总量的19.85%和13.32%;矿质元素种类丰富,钙、铁、锌、锰等微量元素含量高。研究表明,斑纹小贻贝软体部氨基酸比例符合FAO/WHO的理想蛋白模式,蛋白质营养价值高,不饱和脂肪酸含量高,矿质元素含量丰富,具有成为优质保健食品的潜力。

生物入侵是继栖息地破坏之后,全球生物多样性丧失的第二大驱动因素。近年来,原产于南美洲地区的斑纹小贻贝(Mytella strigata)在印度-西太平洋海区被陆续报道,而我国台湾地区、广东、海南、福建、广西等省份同样发现斑纹小贻贝,且其已经建立可自我维持的种群。但是,作为一种新型入侵生物,斑纹小贻贝尚未引起国内海洋管理部门和科研人员足够重视,亟待查明其在我国沿海的分布现状、扩散趋势和生态影响等,为斑纹小贻贝的检测、监测、防控和管理提供科学依据。综述了斑纹小贻贝的基础生物学特征和全球生物入侵现状,发现国内的斑纹小贻贝源于南美洲加勒比海地区,于2014年左右通过船舶压舱水或船体生物污损的形式侵入我国南方沿海并迅速扩散。此外,斑纹小贻贝在我国的生物入侵处于“引进-传播”阶段,即将大规模扩繁,因此亟需开展应急清除行动。
