| 1 | Effects of Xiangsha Liujunzi decoction drug serum on gastric antrum smooth muscle cells from rats with functional dyspepsia by regulating gastrointestinal hormones显示文摘Objective:To observe the effect and mechanism of Xiangsha Liujunzi decoction(XSLJZD)drug serum on gastric antrum smooth muscle cells(SMCs)in rats with functional dyspepsia(FD).Methods:Gastric antrum SMCs from rats with FD were isolated,cultured,and then divided into six groups as follows:control,model,domperidone,low-dose XSLJZD(LXSLJZD),medium-dose XSLJZD(MXSLJZD),and high-dose XSLJZD(HXSLJZD).Each group was administered the corresponding drug serum for intervention.Drug serum intervention conditions and proliferative activity of SMCs were tested by cholecystokinin octapeptide.Ghrelin,gastrin,somatostatin,and substance P(SP)levels were measured by ELISA.Somatostatin and SP mRNA expression was measured by real-time PCR.Results:A concentration of 10%drug serum for 24 h was decided to be the best intervention condition for later study.The mean optical density value in the model group was lower than that in the control group(P紏.001).Optical density values in the domperidone and HXSLJZD groups were higher than those in the model group(P?.025,P?.032,respectively).Gastrin,SP,and ghrelin levels in the model group were lower(P?.007,P?.037,P?.005,respectively),but somatostatin levels were higher,compared with those in the control group(P?.031).Gastrin,SP,and ghrelin levels in the domperidone,MXSLJZD,and HXSLJZD groups were higher than those in the model group(all P<.05).Somatostatin levels in the four drug-treated groups were lower than those in the model group(P?.002,P?.007,P?.001,P?.009,respectively).SP mRNA levels in the model group were lower than those in the control,domperidone,MXSLJZD,and HXSLJZD groups(P?.037 P?.016,P?.025,P?.002,respectively).Somatostatin mRNA levels in the model group were higher than those in the control and MXSLJZD groups(P紏.042,P紏.035).Conclusions:XSLJZD and domperidone drug serum effectively promote proliferative activity of gastric antrum SMCs in an FD model.The mechanism of this activity may be regulated by gastrointestinal hormones. | Ning Dai Jinghong Hu Yan Liu Dongyu Ge Ruijuan Dong Fengzhi Wu Jiaojiao Yu Mindan Chen Deborah CMa Feng Li | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，1： | 6 |
| 2 | The chromosome-level Hemerocallis citrina Borani genome provides new insights into the rutin biosynthesis and the lack of colchicine显示文摘Hemerocallis citrina Borani(huang hua cai in Chinese)is an important horticultural crop whose flower buds are widely consumed as a delicious vegetable in Asia.Here we assembled a high-quality reference genome of H.citrina using single-molecule sequencing and Hi-C technologies.The genome assembly was 3.77 Gb and consisted of 3183 contigs with a contig N50 of 2.09 Mb,which were further clustered into 11 pseudochromosomes.A larger portion(3.25 Gb or 86.20%)was annotated as a repetitive content and 54,295 protein-coding genes were annotated in the genome.Genome evolution analysis showed that H.citrina experienced a recent whole-genome duplication(WGD)event at~15.73 million years ago(Mya),which was the main factor leading to many multiple copies of orthologous genes.We used this reference genome to predict 20 genes involved in the rutin biosynthesis pathway.Moreover,our metabolomics data revealed neither colchicine nor its precursors in H.citrina,challenging the long-standing belief that this alkaloid causes poisoning by the plant.The results of our disruptive research are further substantiated by our genomic finding that H.citrina does not contain any genes involved in colchicine biosynthesis.The high-quality genome lays a solid foundation for genetic research and molecular breeding of H.citrina. | Zhixing Qing Jinghong Liu Xinxin Yi Xiubin Liu Guoan Hu Jia Lao Wei He Zihui Yang Xiaoyan Zou Mengshan Sun Peng Huang Jianguo Zeng | 2021 | Horticulture Research2021，8，1： | 6 |

| 4 | Viral vectors as a novel tool for clinical and neuropsychiatric research applications显示文摘Background A viral vector is a genetically modified vector produced by genetic engineering. As pathogenic genes in the virus are completely or largely eliminated, it is safe to be widely used in multidisciplinary research fields for expressing genes, such as neuroscience, metabolism, oncology and so on. Neuroscience and psychiatry are the most closely related disciplines in either basic research or clinical research, but the application of viral vectors in neuropsychiatry has not received much attention or not been widely accepted.Aim This article will focus on the application of viral vectors in basic and clinical neuropsychiatric research.Methods By using viral vectors, scientists can perform neurological labelling, gene expression regulation and physiological manipulation for investigating phenomenon from molecular mechanisms to behaviours. At the same time, to treat mental or neurological disorders, viral vectors can be designed for gene therapy, which alter gene expression levels or repair mutated genes in the brains of patients.Perspective Viral vectors play an important role in basic research and clinical applications. To further understand brain function and prevent mental and neurological diseases, we hypothesize that viral vectors could be used along with various advanced technologies, such as sequencing and high-throughput expression analysis in the neuroscience research field. | Yao Wang Zhiwei Hu Peijun Ju Shan Yin Fujie Wang Oudong Pan Jinghong Chen | 2018 | General Psychiatry2018，31，5： | 2 |

| 10 | High-temperature mechanical behavior of ultra-coarse cemented carbide with grain strengthening显示文摘Ultra-coarse grained cemented carbides are often used under conditions of concurrently applied stress and high temperature.Improvement of high-temperature mechanical performance of ultra-coarse grained cemented carbides is highly desirable but still a big challenge.In this study,it is proposed that the hightemperature compression strength of ultra-coarse cemented carbides can be enhanced by modulating hard matrix grains by activated Ta C nanoparticles,through solid solution strengthening of Ta atoms.Based on the designed experiments and microstructural characterizations combined with finite element simulations,the grain morphology,stress distribution and dislocation configuration were studied in detail for ultra-coarse grained cemented carbides.The mechanisms of Ta dissolving in WC crystal and strengthening ultra-coarse grains through interaction with dislocations were disclosed from the atomic scale.This study opens a new perspective to modulate hard phases of cemented carbides for improving their hightemperature performance,which will be applicable to a variety of cermet and ceramic-based composite materials. | Huaxin Hu Xuemei Liu Jinghong Chen Hao Lu Chao Liu Haibin Wang Junhua Luan Zengbao Jiao Yong Liu Xiaoyan Song | 2022 | Journal of Materials Science & Technology2022，，9： | 0 |
| 11 | Excitatory somatostatin interneurons in the dentate gyrus drive a widespread seizure network in cortical dysplasia显示文摘Seizures due to cortical dysplasia are notorious for their poor prognosis even with medications and surgery,likely due to the widespread seizure network.Previous studies have primarily focused on the disruption of dysplastic lesions,rather than remote regions such as the hippocampus.Here,we first quantified the epileptogenicity of the hippocampus in patients with late-stage cortical dysplasia.We further investigated the cellular substrates leading to the epileptic hippocampus,using multiscale tools including calcium imaging,optogenetics,immunohistochemistry and electrophysiology.For the first time,we revealed the role of hippocampal somatostatin-positive interneurons in cortical dysplasia-related seizures.Somatostatin-positive were recruited during cortical dysplasia-related seizures.Interestingly,optogenetic studies suggested that somatostatin-positive interneurons paradoxically facilitated seizure generalization.By contrast,parvalbumin-positive interneurons retained an inhibitory role as in controls.Electrophysiological recordings and immunohistochemical studies revealed glutamate-mediated excitatory transmission from somatostatin-positive interneurons in the dentate gyrus.Taken together,our study reveals a novel role of excitatory somatostatin-positive neurons in the seizure network and brings new insights into the cellular basis of cortical dysplasia. | Yang Zheng Cenglin Xu Jinyi Sun Wenjie Ming Sijie Dai Yuying Shao Xiaoyun Qiu Menghan Li Chunhong Shen Jinghong Xu Fan Fei Jiajia Fang Xuhong Jiang Guoqing Zheng Weiwei Hu Yi Wang Shuang Wang Meiping Ding Zhong Chen | 2023 | Signal Transduction and Targeted Therapy2023，8，6： | 0 |
