Amphipods are extremely diverse malacostracan crustaceans that have conquered many environments from oceanic abysses to the terrestrial realm. Despite their impressive modern diversity and abundance, they are particularly rare in the fossil record. Herein, we describe the exceptionally preserved Gammaroidorum yooling sp. nov. from the Late Neogene of Xiaobai Formation near Pandao village, Shanxi, China. Due to the limitation of the preservation, namely the non-preservation of setae, we could not establish a precise generic assignment, so used the collective group Gammaroidorum Jarzembowski, Chény, Fang & Wang, 2020. Although there are still doubts on the precise placement of this new species within amphipods, these fossils are important since they represent the first known fossil occurrence of an amphipod in China. Besides, these fossils have an unusual preservation, being almost transparent in most cases, and being most easily seen by reflecting light on the fossil.

Phosphoenolpyruvate carboxylase (PEPC) is a key enzyme in photosynthesis of C4 plants and plays an important role in a variety of metabolic and stress pathways. In this study, we identified six candidate PEPC genes from foxtail millet genome via sequence alignment. The characteristic parameters of all SiPEPC protein were very similar and the sequences were very conservative. All SiPEPC genes contained the PEPcase motif, which is the characteristic domain of PEPC gene. SiPEPCs were localized in cytoplasm, nucleus and mitochondrion. Promoter analysis identified a variety of light, hormonal, stress, and other growth-related cis-elements in the promoter sequences of SiPEPC members. The qRT-PCR expression profiles showed that the five SiPEPC genes ( SiPEPC1 , SiPEPC2 , SiPEPC3 , SiPEPC5 , SiPEPC6 ) were induced by ABA, PEG, high salt and low temperature at seedling stage, indicating that five SiPEPC genes ate involved in abiotic signaling pathway at the seedling stage. The expression of five SiPEPC genes increased with the growth of foxtail millet under normal growth conditions, and increased significantly under drought stress at different growth stages, indicating that five SiPEPCs are involved in drought stress response at jointing, heading and filling stages. The weak light at jointing stage could induce the expression of five SiPEPC genes, while the expression level decreased sharply under moderate light intensity at jointing stage, moderate and weak light intensity at heading and filling stages, showing that light intensity seriously affects the expression of SiPEPC genes.

Purpose：To study the influence of Dachuanxiong gelata on the nitric oxide, nitric oxide synthase and calcitonin gene-related peptide in plasma of rat that has a headache. Methods: Make the migraine rat models through the subcutaneous injection of nitroglycerin and divide the experiment into blank control group, migraine model group, experimental drug group and positive drug group. The Dachuanxiong gelata should be given through intragastric administration at 20 times (high), 10 times (middle) and 5 times (low) of 60 kg adult clinical dosage (30 g crude drug/60kg), respectively 11.67, 5.83 and 2.92g crude drug/ kg#d; the distilled water with the same volume should be given to the rats in the model group and normal group through intragastric administration and that of 2mg should be given to rats in the ergotamine and caffeine group through intragastric administration. The kit should be used to detect the contents of NO, NOS and CGRP in the rat plasma. Results：The content of NO in plasma of model group rises and it has significant difference (P
