| 1 | T cell–associated immunoregulation and antiviral effect of oxymatrine in hydrodynamic injection HBV mouse model显示文摘Although oxymatrine(OMT) has been shown to directly inhibit the replication of hepatitis B virus(HBV) in vitro, limited research has been done with this drug in vivo. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection.The infection was achieved by tail vein injection of a large volume of DNA solution. OMT(2.2, 6.7 and20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen(HBs Ag), hepatitis B e antigen(HBe Ag)and hepatitis B core antigen(HBc Ag). The immunoregulatory activity of OMT was evaluated by serum ELISA and flow cytometry. Results shows that OMT at 20 mg/kg inhibited HBV replication, and it was more efficient than entecavir(ETV) in the elimination of serum HBs Ag and intrahepatic HBc Ag. Inaddition, OMT accelerated the production of interferon-γ(IFN-γ) in a dose-dependent manner in CD4^+T cells. Our findings demonstrate the beneficial effects of OMT on the enhancement of immunological function and in the control of HBV antigens. The findings suggest this drug to be a good antiviral therapeutic candidate for the treatment of HBV infection. | Xiuxiu Sang Ruilin Wang Yanzhong Han Cong’en Zhang Honghui Shen Zhirui Yang Yin Xiong Huimin Liu Shijing Liu Ruisheng Li Ruichuang Yang Jiabo Wang Xuejun Wang Zhaofang Bai Xiaohe Xiao | 2017 | Acta Pharmaceutica Sinica B2017，7，3： | 20 |
| 2 | Landscape of DILI-related adverse drug reaction in China Mainland显示文摘Drug-induced liver injury(DILI)is a type of bizarre adverse drug reaction(ADR)damaging liver(L-ADR)which may lead to substantial hospitalizations and mortality.Due to the general low incidence,detection of L-ADR remains an unsolved public health challenge.Therefore,we used the data of 6.673 million of ADR reports from January 1st,2012 to December 31st,2016 in China National ADR Monitoring System to establish a new database of L-ADR reports for future investigation.Results showed that totally 114,357 ADR reports were retrieved by keywords searching of liver-related injuries from the original heterogeneous system.By cleaning and standardizing the data fields by the dictionary of synonyms and English translation,we resulted 94,593 ADR records reported to liver injury and then created a new database ready for computer mining.The reporting status of L-ADR showed a persistent 1.62-fold change over the past five years.The national population-adjusted reporting numbers of L-ADR manifested an upward trend with age increasing and more evident in men.The annual reporting rate of L-ADR in age group over 80 years old strikingly exceeded the annual DILI incidence rate in general population,despite known underreporting situation in spontaneous ADR reporting system.The percentage of herbal and traditional medicines(H/TM)L-ADR reports in the whole number was 4.5%,while 80.60%of the H/TM reports were new findings.There was great geographical disparity of reported agents,i.e.more cardiovascular and antineoplastic agents were reported in higher socio-demographic index(SDI)regions and more antimicrobials,especially antitubercular agents,were reported in lower SDI regions.In conclusion,this study presented a large-scale,unbiased,unified,and computer-minable L-ADR database for further investigation.Age-,sex-and SDI-related risks of L-ADR incidence warrant to emphasize the precise pharmacovigilance policies within China or other regions in the world. | Jiabo Wang Haibo Song Feilin Ge Peng Xiong Jing Jing Tingting He Yuming Guo Zhuo Shi Chao Zhou Zixin Han Yanzhong Han Ming Niu Zhaofang Bai Guangbin Luo Chuanyong Shen Xiaohe Xiao | 2022 | Acta Pharmaceutica Sinica B2022，12，12： | 12 |
| 3 | Transcriptome Profiling of the Abdominal Skin of Larimichthys crocea in Light Stress显示文摘Large yellow croaker(Larimichthys crocea), one of the most important marine fish species in China, can change its abdominal skin color when it is shifted from light to dark or from dark to light, providing us an opportunity of investigating the molecular responding mechanism of teleost in light stress. The gene expression profile of fish under light stress is rarely documented. In this research, the transcriptome profiles of the abdominal skin of L. crocea exposed to light or dark for 0 h, 0.5 h and 2 h were produced by next-generation sequencing(NGS). The cluster results demonstrated that stress period, rather than light intensity(e.g., light or dark), is the major influencing factor. Differently expressed genes(DEGs) were identified between 0 h and 0.5 h groups, between 0 h and 2 h groups, between 0.5 h light and 0.5 h dark, and between 2 h light and 2 h dark, respectively. The gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) annotation revealed that the genes relating to immunity, energy metabolism, and cytoskeletal protein binding were significantly enriched. The detailed analysis of transcriptome profiles also revealed regular gene expression trends, indicating that the elaborate gene regulation networks underlined the molecular responses of the fish to light stress. This transcriptome analysis suggested that systematic and complicated regulatory cascades were functionally activated in response to external stress, and coloration change caused by light stress was mainly attributed to the change in the density of chromatophores for L. crocea. This study also provided valuable information for skin coloration or light stress research on other marine fish species. | HAN Zhaofang LV Changhuan XIAO Shijun YE Kun ZHANG Dongling TSAI Huai Jen WANG Zhiyong | 2018 | Journal of Ocean University of China2018，17，2： | 2 |
| 4 | Genome-wide association study identifies loci for body shape in the large yellow croaker(Larimichthys crocea)显示文摘The large yellow croaker(Larimichthys crocea)is an important maricultured fish species in southeast China.Body shape is an important economic trait for this species,because consumers prefer to purchase fish that have a slender shape.Furthermore,investigating the genetic basis of this trait may be useful for understanding the evolution of fish body shape in general.This study randomly selected 500 large yellow croakers to perform genome-wide association study of this trait.We used Genotyping-By-Sequencing technology combined with a genome-wide prediction model(BayesC)to identify and test QTLs.We also compared the association results using BayesC and single-marker analysis,and found that BayesC outperformed single-marker analysis in detecting significant SNPs explaining a proportion of the total genetic variance in this experiment.Using 124,419 SNP markers,10 candidate genes,correspond to 4 QTL regions located around 3.5,1.8,23.9 and 10.8 Mb on chromosomes 2,4,8 and 22 respectively,were suggested to be relevant to the trait.All of these genes may directly or indirectly participate in bone development.These genes may provide a valuable reference for marker-assisted selective breeding and investigating the genetic basis of the evolution of fish body shape. | Linsong Dong Zhaofang Han Ming Fang Shijun Xiao Zhiyong Wang | 2019 | Aquaculture and Fisheries2019，4，1： | 1 |
