金乌贼作为我国重要的头足类资源,具有较高的经济价值和营养价值。本文基于2.17—2.2.年当年9月到翌年3月在东海中部(12..0°E~12..5°E,2..5°N~31.5°N)拖网调查采集的金乌贼样本,分析其胴长和体质量组成、性腺发育以及初次性成熟胴长L_(50)。结果显示,金乌贼雌雄个体优势胴长组分别为81~12. mm、81~140 mm;优势体质量组分别为41~2.0 g、41~2.0 g。金乌贼性腺发育低的个体生长快于性腺发育高的个体;且雌性生长快于雄性。调查期间,性腺随时间发育,161 mm以上的胴长组中未有Ⅰ期个体被发现。应用逻辑斯蒂方程和多项式胴长体质量模型估算L_(50)结果:雌性12..30和12..98 mm、雄性12..18和142.44 mm,基于多项式胴长体质量方程估算的L_(50)拟合效果更好。金乌贼存在明显的季节性生殖特征,在采样时间内繁殖期为1—3月;雌性在性成熟期间能量更多地从身体生长转变为性腺发育且生长模式的转变明显早于雄性;为便于渔民捕捞且保证捕捞个体均已达到性成熟,建议东海中部海域金乌贼最小开捕胴长应当大于142.mm。

High-energy Li-metal batteries (LMBs) suffer from short cycle life and safety issues due to severe parasitic reactions and dendrite growth of Li metal anode (LMA) in liquid electrolytes [1–3].It is generally believed that replacing liquid electrolytes with solidstate electrolytes (SSEs) would be a feasible approach for practical LMBs [4,5]. Conventional SSEs including ceramic and polymer electrolytes have been studied for decades.

Cystinosis and some other diseases are characterized by high concentrations of cystine in urine(usually>400 mg L-1).Until now many methods have been developed to detect cystine in human urine,such as iodimetry,[1]electrochemitry,[2.high-performance liquid chromatography,[3]fluorimetry[4]and colorimetry.[5]Among these methods,colorimetric assay is the most attractive analytical method,especially in a resource poor setting,due to its simplicity,easy observation by the naked eye and no requirement for sophisticated

洪泽凹陷赵集次凹岩盐矿产资源丰富,勘探前景广阔,已有近30年盐矿开采历史。2.19年2.2.日,赵集次凹盐矿区西北部勘探孔TY1孔发生涌水,水头高、水量大、持续时间长。通过分析区域岩盐生产情况,并将TY1孔与盐矿区其他涌水井的涌水特征、涌水层位岩性进行综合对比,认为该勘探井涌水为较强的紊流运动,区域内盐矿开采产生的次生裂隙是该孔紊流性涌水的主要原因。为更好地保障淮安盐矿及盐穴资源的科学和高效利用,提出了区域盐矿统一规划、严格监管和科学开采的建议。

Buxue Yimu Pill(BYP) is a classic gynecological medicine in China, which is composed of Angelica sinensis(Oliv.)Diels, Leonurus japonicus Houtt, Astragalus membranaceus(Fisch.) Bunge, Colla corii asini and Citrus reticulata Blanco. It has been widely used in clinical therapy with the function of enriching Blood, nourishing Qi, and removing blood stasis. The current study was designed to determine the bioactive molecules and therapeutic mechanism of BYP against hemorrhagic anemia. Herein, GC-MS and UPLC/Q-TOF-MS/MS were employed to identify the chemical compounds from BYP. The genecards database(https://***/) was used to obtain the potential target proteins related to hemorrhagic anemia. Autodock/Vina was adopted to evaluate the binding ability of protein receptors and chemical ligands. Gene ontology and KEGG pathway enrichment analysis were conducted using the Cluster Profiler. As a result, a total of 62.candidate molecules were identified and 152.targets related to hemorrhagic anemia were obtained. Furthermore, 34 active molecules and 140 targets were obtained through the virtual screening experiment. The data of molecular-target(M-T), target-pathway(T-P), and molecular-target-pathway(M-T-P) network suggested that 32.active molecules enhanced hematopoiesis and activated the immune system by regulating 57 important targets. Pharmacological experiments showed that BYP significantly increased the counts of RBC, HGB, and HCT, and significantly down-regulated the expression of EPO, IL-6, CSF3,NOS2. VEGFA, PDGFRB, and TGFB1. The results also showed that leonurine, leonuriside B, leosibiricin, ononin, rutin, astragaloside I, riligustilide and levistolide A, were the active molecules closely related to enriching Blood. In conclusion, based on molecular docking, network pharmacology and validation experiment results, the enriching blood effect of BYP on hemorrhagic anemia may be associated with hematopoiesis, anti-inflammation, and immunity enhancement.
