| 5 | Comparison of different methods of intestinal obstruction in a rat model显示文摘AIM:To investigate different methods of creating incomplete intestinal obstruction in a rat model and to compare their electrophysiologic,morphologic and histologic characteristics. METHODS:Rat ileum was partially obstructed by the respective application of:braided silk(penetrated the mesentery and surrounded intestine);half ligation (penetrated directly and ligated 1/2 cross-section of the intestine);wide pipe(6 mm in width,surrounded the intestine);narrow pipe(2 mm in width,surrounded the intestine).A control was also included(no obstruction). Various behavioral and electrophysiologic variables, as well as morphologic and immunohistochemical observations were recorded by blinded investigators at different time points(12,24,48,72 h),including daily general condition,ileal wet weight and circumference, macromorphous and micromorphous intestine,bowel movement capability in vivo and in vitro,slow wave and neural electrical activity,and the number of c-Kit positive interstitial cells of Cajal(ICC). RESULTS:Despite being of a similar general condition, these methods resulted in different levels of obstruction in each group compared with the control at different time points(12,24,48,72 h).However,these fields of the wide pipe rat showed significantly differences when compared with the other three obstructed groups at 12 to 72 h,including macroscopic and histological presentation,intestinal transit ratio and contractility,circumference and wet weight,amplitude and frequency of nerve electrical discharge and slow wave,and ICC numbers(all P<0.01). CONCLUSION:The wide pipe rat method is significantly more reliable and stable than the other methods of obstruction,demonstrating that use of the wide pipe method can be a useful model of incomplete intestinal obstruction. | Meng-Lang Yuan Zheng Yang Yu-Cheng Li Lan-Lan Shi Jia-Ling Guo Yu-Qin Huang Xia Kang Jing-Jing Cheng Yang Chen Ting Yu De-Qi Cao Huan Pang Xiao Zhang | 2013 | World Journal of Gastroenterology2013，19，5： | 10 |

| 7 | Effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats显示文摘Objective To study the effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats. Methods Rat tail-suspension model was used to simulate the physiological effects of microgravity and changes in pulmonary blood vessel morphology, pulmonary arterial and venous blood pressure, pulmonary vascular resistance, pulmonary vasomotoricity, as well as the regulation of pulmonary circulation by cytokines produced and released by the lung of rats were measured. Results The walls of pulmonary blood vessels of rats were thickened, and the pulmonary artery was reconstructed with increased pulmonary vascular resistance. The pulmonary blood vessels of rats became more prone to dilation as contractions increased. Rat epithelial Adrenomedulin gene transcription and protein expression were upregulated. The level of basic fibroblast growth Factor of rat was also elevated. Conclusion Findings from the present study on rats revealed that the microgravity can affect pulmonary blood vessel structure, pulmonary arterial pressure, and pulmonary blood vessel self-regulation and cytokine production. | LI Tian Zhi YUAN Ming CHEN Zhen Hong GUO Ying Hua KANG Chun Yan WANG Jing Yu LI Zhi Li WANG De Sheng WANG Hui Juan YUAN Min LIU Chang Ting | 2013 | Biomedical and Environmental Sciences2013，26，2： | 6 |

| 12 | Inhibition of Re Du Ning Injection on Enzyme Activities of Rat Liver Microsomes Using Cocktail Method显示文摘Objective Re Du Ning Injection(RDN), a Chinese materia medica injection, is made from the extracts of Lonicerae Japonicae Flos, Gardeniae Fructus, and Artemisiae Annuae Herba. Since last decade, RDN has been widely used in China for the treatment of viral infection, fever, and inflammation. To assess the potential interacting of RDN with co-administered drugs, the inhibitory effects of RDN on the enzyme activities(CYP1A1, CYP1A2, CYP2C11, CYP2D1, and CYP3A1/2) of rat liver microsomes were investigated by a cocktail method. Methods A sensitive and specific LC-MS method capable of simultaneous quantification of five metabolites in rat liver microsomes was developed and validated. Then RDN(0.625%–1.0%) was incubated with rat liver microsomes and specific substrates. The enzyme activities were expressed as the formation rate of the specific metabolites of the substrates(pmol·mg·protein-1·min-1). Results RDN competitively inhibited the activities of CYP1A2 and CYP2C11, with inhibition constant(Ki) values determined to be 0.18% and 0.63%, respectively. RDN exhibited the mixed inhibition on the activity of CYP2D1, with a Ki value of 0.15%. The activities of CYP1A1 and CYP3A1/2 were not markedly inhibited even by 1.0% RDN. Conclusion RDN could inhibit the rat enzyme activities of CYP1A2, 2C11, and 2D1 in vitro with different inhibition modes, which is worthy of promoting safety and efficacy of RDN. | Xiao-qian Xu Ting Geng She-bing Zhang Dan-yu Kang Yan-jing Li Gang Ding Wen-zhe Huang Zhen-zhong Wang Wei Xiao | 2016 | Chinese Herbal Medicines2016，8，3： | 4 |

| 14 | Roxadustat as treatment for a blood transfusion-dependent maintenance hemodialysis patient:A case report and review of literature显示文摘BACKGROUND Erythropoiesis-stimulating agents(ESAs)have revolutionized the therapeutic strategy for anemia in chronic kidney disease.However,some cases are resistant or hyporesponsive to ESAs.Roxadustat is an oral hypoxia-inducible factor-prolyl hydroxylase inhibitor that stimulates erythropoiesis and regulates iron metabolism.Here,we describe a hemodialysis patient with refractory anemia who did not respond to traditional treatments and depended on blood transfusion for more than 1 year.After applying Roxadustat,the patient’s anemia improved significantly.CASE SUMMARY A 44-year-old man was diagnosed with uremia accompanied by severe anemia with a hemoglobin(Hb)level ranging from 30-40 g/L.His anemia did not improve after sufficient dialysis or high doses of active ESAs;other causes of anemia were excluded.The patient required approximately 600-1000 mL of red blood cell suspension every 15-30 d for more than 1 year.After accepting Roxadustat therapy,the patient’s anemia symptoms improved significantly;his Hb level gradually increased to 50 g/L,and no further blood transfusions were administered.His Hb level reached 69 g/L by the 34th week.Although a Hb level of 60-70 g/L cannot be considered satisfactory,he no longer required blood transfusions and his quality of life was substantially improved.Roxadustat showed good efficacy and safety in this case.CONCLUSION Roxadustat represents an innovative and effective agent for the clinical treatment of renal anemia caused by multiple complex factors. | Min Fei Xiang-Qiong Wen Zhao-Lan Yu Ting Kang Wei-Hua Wu San-Tao Ou | 2021 | World Journal of Clinical Cases2021，9，15： | 4 |
| 15 | Multidrug-resistant Proteus mirabilis isolates carrying blaOXA-1 and blaNDM-1 from wildlife in China:increasing public health risk显示文摘The emergence of multidrug resistance(MDR)in Proteus mirabilis clinical isolates is a growing public health concern and has serious implications for wildlife.What is the role of wildlife has been become one of the hot issues in disseminating antimicrobial resistance.Here,54 P.mirabilis isolates from 12 different species were identified.Among them,25 isolates were determined to be MDR by profile of antimicrobial susceptibility;10 MDR P.mirabilis isolates were subjected to comparative genomic analysis by whole genome sequencing.Comprehensive analysis showed that chromosome of P.mirabilis isolates mainly carries multidrug-resistance complex elements harboring resistance to carbapenem genes blaOXA-1,blaNDM-1,and blaTEM-1.Class I integron is the insertion hotspot of IS26;it can be inserted into type I integron at different sites,thus forming a variety of multiple drug resistance decision sites.At the same time,Tn21,Tn7,and SXT/R391 mobile elements cause widespread spread of these drug resistance genes.In conclusion,P.mirabilis isolates from wildlife showed higher resistance to commonly used clinic drugs comparing to those from human.Therefore,wild animals carrying MDR clinical isolates should be paid attention to by the public health. | Qian KANG Xue WANG Jianan ZHAO Zhihui LIU Fang JI Han CHANG Jianchun YANG Shijia HU Ting JIA Xiaojia WANG Jiagui TANG Guoying DONG Guocheng HU Jing WANG Yanyu ZHANG Jianhua QIN Chengmin WANG | 2021 | Integrative Zoology2021，16，6： | 4 |
| 16 | Arabidopsis ROOT HAIR DEFECTIVE3 is involved in nitrogen starvation-induced anthocyanin accumulation显示文摘Anthocyanin accumulation is a common phenomenon seen in plants under environmental stress. In this study,we identified a new allele of ROOT HAIR DEFECTIVE3(RHD3)showing an anthocyanin overaccumulation phenotype under nitrogen starvation conditions. It is known that ethylene negatively regulates light- and sucrose-induced anthocyanin biosynthesis. We hypothesized that RHD3 achieves its negative effect on anthocyanin biosynthesis via an ethylene-regulating pathway. In support of this, similar to rhd3 mutants, the Arabidopsis ethylene signaling mutants etr1, ein2, and ein3/eil1 showed an anthocyanin overaccumulation phenotype under nitrogen starvation conditions. The ethylene precursor ACC strongly suppressed anthocyanin accumulation, dependent on ETR1, EIN2, EIN3/EIL1, and, partially, RHD3. In addition,inactivating RHD3 partially reversed the suppressive effect of ETO1 inactivation-evoked endogenous ethylene production on anthocyanin accumulation. The expression of nitrogen starvation-induced anthocyanin biosynthesis genes was negatively regulated by RHD3, but ethylene response genes were Researchpositively regulated by RHD3. Wild-type seedlings overexpressing RHD3 showed similar phenotypes to rhd3 mutants,indicating the existence of a fine-tuned relationship between gene expression and function. RHD3 was initially identified as a gene involved in root hair development. This study uncovered a new physiological function of RHD3 in nitrogen starvationinduced anthocyanin accumulation and ethylene homeostasis. | Jing Wang Yan Wang Ju Yang Chunli Ma Ying Zhang Ting Ge Zhi Qi Yan Kang | 2015 | Journal of Integrative Plant Biology2015，57，8： | 3 |
| 17 | DCZ0801,a novel compound,induces cell apoptosis and cell cycle arrest via MAPK pathway in multiple myeloma显示文摘Multiple myeloma(MM)is a refractory malignant hematological malignancy,and many therapeutic strategies have been developed to cure patients with MM.DCZ0801 is a compound that consists of oxophenamide and pterostilbene.The role of these compounds in hematological cancers such as MM has yet to be studied.In this study,we explored the potential mechanism of DCZ0801 action,its anti-tumor activity both in vitro and in vivo on MM.This study was carried out via cell cycle proliferation assay,apoptotic analysis,western blot analysis,and examination of xenotransplantation model of tumors.The in vitro studies revealed that DCZ0801 could inhibit cell proliferation and induce apoptosis by regulating both caspase-dependent and mitogen-activated protein kinase signaling pathways,inducing S-phase arrest of the cell cycle related to downregulation of CDK2,cyclin-A2,and CDC25A protein expression.The in vivo studies showed that DCZ0801 could significantly reduce the size of the tumors in nude mice.Our results demonstrated that DCZ0801 may emerge as the new therapeutic option for the patient with MM. | Ting Zhang Bo Li Qilin Feng Zhijian Xu Cheng Huang Huiqun Wu Zhangbo Chen Liangning Hu Lu Gao Peng Liu Guang Yang Hui Zhang Kang Lu Tingye Li Yi Tao Xiaosong Wu Jumei Shi Weiliang Zhu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，5： | 3 |
| 18 | The effect of monosialylganglioside mix modifying the PEGylated liposomal epirubicin on the accelerated blood clearance phenomenon显示文摘PEGylated liposomes are potential candidates to improve the pharmacokinetic characteristics of encapsulated drugs, to extend their circulation half-life and facilitate their passive accumulation at tumour sites. However, PEG-modified liposomes can induce accelerated blood clearance(ABC) upon repeated administration, and the extent of ABC phenomenon on the cytotoxic drugs-containing PEGylated liposomes is related to the dose of the cytotoxic drugs.In this study, EPI served as a model cytotoxic drug, a hydrophilic surfactant molecule,monosialylganglioside(GM1) was chosen and modified on the liposomes together with PEG.It was shown that upon mixed modification, when GM1 contents reached 10% or 15% mol,the ABC phenomenon of the PEGylated liposomal EPI significantly reduced. We also found that GM1 played an important role in abrogating the ABC phenomenon in both the induction phase and the effectuation phase. The results suggested that GM1 incorporation unfortunately did not avoid occurrence of ABC phenomenon completely, but GM1 modification on PEGylated liposomes may provide a significant improvement in clinical practice of PEGylated liposomes. Further study must be necessary. | Ting Zhang Songlei Zhou Le Kang Xiang Luo Yang Liu Yanzhi Song Xinrong Liu Yihui Deng | 2017 | Asian Journal of Pharmaceutical Sciences2017，12，2： | 3 |
| 19 | Differential transcriptome analysis between Populus and its synthesized allotriploids driven by second-division restitution显示文摘In this report, we compared transcriptomic differences between a synthetic Populus section Tacamahaca triploid driven by second-division restitution and its parents using a high-throughput RNA-seq method. A total of 4,080 genes were differentially expressed between the high-growth vigor allotriploids(SDR-H) and their parents, and 719 genes were non-additively expressed in SDR-H. Differences in gene expression between the allotriploid and male parent were more signi ficant than those between the allotriploid and female parent, which may be caused by maternal effects. We observed3,559 differentially expressed genes(DEGs) between the SDR-H and male parent. Notably, the genes were mainly involved in metabolic process, cell proliferation, DNA methylation, cell division, and meristem and developmental growth. Among the1,056 DEGs between SDR-H and female parent, many genes were associated with metabolic process and carbon utilization.In addition, 1,789 DEGs between high- and low-growth vigor allotriploid were mainly associated with metabolic process,auxin poplar transport, and regulation of meristem growth.Our results indicated that the higher poplar ploidy level can generate extensive transcriptomic diversity compared with its parents. Overall, these results increased our understanding of the driving force for phenotypic variation and adaptation in allopolyploids driven by second-division restitution. | Shiping Cheng Zhen Huang Yun Li Ting Liao Yujing Suo Pingdong Zhang Jun Wang Xiangyang Kang | 2015 | Journal of Integrative Plant Biology2015，57，12： | 3 |
