| 6 | Protective Effect of Ganshuang Granules(肝爽颗粒)on Liver Cirrhosis by Suppressing Regulatory T Cells in Mouse Model显示文摘Objective: To investigate the potential antifibrotic mechanisms of Chinese medicine Ganshuang Granules(肝爽颗粒, GSG) and to provide clinical therapeutic evidence of its effects. Methods: A cirrhotic mouse model was established by intraperitoneally injecting a mixture of CCl_4(40%) and oil(60%) at 0.2 mL per 100 g of body weight twice a week for 12 weeks. After 12-week modeling, GSG was intragastric administrated to the mice for 2 weeks, and the mice were divided into low-, medium-and high-dose groups at doses of 1, 2 and 4 g/(kg·day), respectively. Liver morphology changes were observed using Masson's trichrome staining and B-ultrasound. The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and hyaluronic acid(HA) in serum were detected using an automatic biochemistry analyzer. The expressions of desmin, smooth muscle actin(SMA) and Foxp3 in liver were detected by immunofluorescence. The regulatory T cell(Treg) frequency was determined through flow cytometry analysis. Collagen-Ⅰ, SMA, IL-6, tumor necrosis factor α(TNF-α), interleukin(IL)-1β and transforming growth factor β1(TGF-β1) expression levels were measured using quantitative polymerase chain reaction(qPCR). Results: Masson's staining result showed fewer pseudolobule structures and fibrous connective tissue in the GSG-treatment groups than in the spontaneous recovery group. Ultrasonography showed that GSG treatment reduced the number of punctate hyperechoic lesions in mice cirrhotic livers. The serum ALT, AST, HA levels were significantly ameliorated by GSG treatment(ALT: F=8.104, P=0.000; AST: F=7.078, P=0.002; and HA: F=7.621, P=0.001). The expression levels of collagen-Ⅰ and SMA in the cirrhotic livers were also attenuated by GSG treatment(collagen-Ⅰ: F=3.938, P=0.011; SMA: F=4.115, P=0.009). Tregs, which were elevated in the fibrotic livers, were suppressed by GSG treatment(F=8.268, P=0.001). The expressions of IL-6, TNF-α and IL-1β increased, and TGF-β levels decreased in the cirrhotic livers after GSG treatment(IL-6: F=5.457, P=0.004; TNF-α: F=6.023, P=0.002; IL-1β: F=6.658, P=0.001; and TGF-β1: F=11.239, P=0.000). Conclusions: GSG promoted the resolution/regression of cirrhosis and restored liver functions in part by suppressing Treg cell differentiation, which may be mediated by hepatic stellate cells. | LIU Yan-min SHI Hong-bo LIU Yi-rong SHI Hong-lin REN Feng CHEN Yu CHEN De-xi LOU Jin-li DUAN Zhong-ping | 2019 | Chinese Journal of Integrative Medicine2019，25，1： | 12 |
| 7 | Downregulation of lncRNA AFAP1-AS1 by oridonin inhibits the epithelial-to-mesenchymal transition and proliferation of pancreatic cancer cells显示文摘Recent studies have demonstrated that the expression of the long non-coding RNA(lncRNA)AFAP1-AS1 in pancreatic cancer is negatively correlated with survival and prognosis.However,the effects of oridonin and lncRNA AFAP1-AS1 on the epithelial-to-mesenchymal transition(EMT)and migration of pancreatic cancer cells have not been fully elucidated.Surgery is the only potentially curative method for pancreatic cancer,but postoperative recurrence and metastasis are common.The aim of the present study was to assess the effect of oridonin and lncRNA AFAP1-AS1 silencing on pancreatic cancer cells.The pancreatic cancer cell lines BxPC-3 and PANC-1 cells were transfected with siAFAP1-AS1 and its negative control(siNC).After that,oridonin was used to treat the siAFAP1-AS1-transfected cells.The expression of lncRNA AFAP1-AS1 was downregulated in the pancreatic cancer cell lines BxPC-3 and PANC-1.The apoptosis and cell cycle progression of pancreatic cancer cells were evaluated by flow cytometry and Hoechst 33258 staining.Metastasis and invasion of BxPC-3 and PANC-1 cells were detected by transwell migration assay,real-time cell analysis,and western blot analysis.Cells were transfected with the lentiviral siAFAP1-AS1 and siNC,and tumorigenesis was evaluated in BALB/C nude mice.Immunohistochemical examination was used to verify the effects of oridonin and siAFAP1-AS1 on pancreatic cancer.The results demonstrated that the combination of oridonin and siAFAP1-AS1 inhibited pancreatic cancer cell proliferation,induced apoptosis,arrested cell cycle progression,prevented the migration,regulated EMT-related protein expression in BxPC-3 and PANC-1 cells,and inhibited pancreatic cancer cell tumorigenicity and EMT in nude mice. | Songmei Lou Jian Xu Bili Wang Shuquan Li Jun Ren Zhengjun Hu Bin Xu Feng Luo | 2019 | Acta Biochimica et Biophysica Sinica2019，51，8： | 10 |
| 8 | Prioritizing natural-selection signals from the deep-sequencing genomic data suggests multi-variant adaptation in Tibetan highlanders显示文摘Human genetic adaptation to high altitudes(>2500 m)has been extensively studied over the last few years,but few functional adaptive genetic variants have been identified,largely owing to the lack of deep-genome sequencing data available to previous studies.Here,w e build a list of putative adaptive variants,including 63 missense,7 loss-of-function;1,298 evolutionarily conserved variants and 509 expression quantitative traits loci.Notably,the top signal of selection is located in TMEM 247,a transmembrane protein-coding gene.The Tibetan version of TMEM 247 harbors one high-frequency(76.3%)missense variant,rsl 16983452(c.248C>T;p.Ala83Val);with the T allele derived from archaic ancestry and carried by>94%of Tibetans but absent or in low frequencies(<3%)in non-Tibetan populations.The rsl 16983452-T is strongly and positively correlated with altitude and significantly associated with reduced hemoglobin concentration(p=5.78×10^-5),red blood cell count(p=5.72×10^-7)and hematocrit(p=2.57×10^-6).In particular,TMEM247-rs 116983452 shows greater effect size and better predicts the phenotypic outcome than any E P A S1 variants in association with adaptive traits in Tibetans.Modeling the interaction between TM£M247-rsl 16983452 and EPAS1 variants indicates weak but statistically significant epistatic effects.Our results support that multiple variants may jointly deliver the fitness of the Tibetans on the plateau,where a complex model is needed to elucidate the adaptive evolution mechanism. | Lian Deng Chao Zhang Kai Yuan Yang Gao Yuwen Pan Xueling Ge Yaoxi He Yuan Yuan Yan Lu Xiaoxi Zhang Hao Chen Haiyi Lou Xiaoji Wang Dongsheng Lu Jiaojiao Liu Lei Tian Qidi Feng Asifullah Khan Yajun Yang Zi-Bing Jin Jian Yang Fan Lu Jia Qu Longli Kang Bing Su Shuhua Xu | 2019 | National Science Review2019，6，6： | 9 |

| 10 | Alternate row mulching optimizes soil temperature and water conditions and improves wheat yield in dryland farming显示文摘Straw mulching allows for effective water storage in dryland wheat production. Finding a suitable straw mulching model that facilitates wheat growth was the objective of this study. A 2-year field experiment was conducted to investigate the effects of two straw mulching patterns(FM, full coverage within all the rows; HM, half coverage within alternate rows) and two mulching rates(4.5 and 9.0 t ha^(–1)) on soil moisture, soil temperature, grain yield, and water use efficiency(WUE) of winter wheat in northern China, with no mulching(M0) as the control. Results showed that mulching increased the soil water storage in all growth stages under high mulching rates, with a stronger effect in later growth stages. Water storage under the HM model was greater in later stages than under the FM model. Soil water content of HM groups was higher than that of FM groups, especially in surface soil layers. Evapotranspiration decreased in mulched groups and was higher under high mulching rates. Aboveground biomass during each growth stage under the HM model was higher than that under M0 and FM models with the same mulched rate, leading to a relatively higher grain yield under the HM model. Mulching increased WUE, a trend that was more obvious under HM9.0 treatment. Warming effect of soil temperature under the HM pattern persisted longer than under the FM model with the same mulching rates. Accumulated soil temperature under mulched treatments increased, and the period of negative soil temperature decreased by 9–12 days under FM and by 10–20 days under HM. Thus, the HM pattern with 9.0 t ha–1 mulching rate is beneficial for both soil temperature and water content management and can contribute to high yields and high WUE for wheat production in China. | YAN Qiu-yan DONG Fei LOU Ge YANG Feng LU Jin-xiu LI Feng ZHANG Jian-cheng LI Jun-hui DUAN Zeng-qiang | 2018 | Journal of Integrative Agriculture2018，17，11： | 8 |

| 12 | Preparation and characterization of m PEG grafted chitosan micelles as 5-fluorouracil carriers for effective anti-tumor activity显示文摘The objective of this study was to investigate the potential of methoxy polyethylene glycol(m PEG)grafted chitosan(m PEG-g-CS) to be used as a drug carrier. m PEG-g-CS was successfully synthesized by one-step method with formaldehyde. The substitution degree of m PEG on chitosan was calculated by elemental analysis and was found to be(3.23 0.25)%. m PEG-g-CS self-assembled micelles were prepared by ultrasonic method with the controlled size of 178.5–195.1 nm and spherical morphology. Stable dispersion of the micelles was formed with the zeta potential of 2.3–30.2 m V. 5-Fluorouracil(5-FU), an anticancer chemotherapy drug, was used as a model drug to evaluate the efficiency of the new drug delivery carrier. The loading efficiency of 5-FU was(4.01 0.03)%, and the drug-loaded m PEG-g-CS self-assembled micelle showed a controlled-release effect. In summary, the m PEG-g-CS self-assembled micelle is proved to be a promising carrier with controlled particle size and controlled-release effect. Therefore, it has great potential for the application as 5-FU carriers for effective anti-tumor activity. | Dong-Jun Fu Yu Jin Mu-Qing Xie Ya-Jing Ye Dong-Dong Qin Kai-Yan Lou Yan-Zuo Chen Feng Gao | 2014 | Chinese Chemical Letters2014，25，11： | 7 |
| 13 | Effect of Gd addition on mechanical and microstructural properties of Mg-xGd-2.6Nd-0.5Zn-0.5Zr cast alloys显示文摘The Mg-xGd-2.6Nd-0.5Zn-0.5Zr(x=0,3.0,4.5 and 6.0,wt.%)alloys were prepared by gravity casting and then T6 treatment.Microstructures of the alloy were observed using optical microscopy and scanning electron microscopy.Results show that the as-cast alloys contained network Mg3Gd phases,blocky and needle-like Mg12(Nd,Gd)phases.The a(Zr)particle inclusions in the a(Mg)matrix are also observed.Content of the secondary phases decreases as Gd content increases.Tensile test results show that the tensile and yield strengths of all the alloys increase as Gd content increases under the as-cast and T6 conditions,but the elongation exhibits the opposite trend.The blocky Mg12(Nd,Gd)phases appear and act as crack initiator and deteriorates the experimental alloys’ductility with the increase of Gd content,especially as Gd content increases to 6.0 wt.%,so the Mg-6.0Gd-2.6Nd-0.5Zn-0.5Zr alloy has the lowest elongation value compared to the other alloys studied.After T6 treatment,the Mg-4.5Gd-2.6Nd-0.5Zn-0.5Zr alloy exhibits the optimal mechanical properties both at room temperature and 250℃. | Liang Zhan Yi-zhi Le Zhi-jun Feng Yan-chun Lou Ming Ruan Hua-wen Li | 2020 | China Foundry2020，17，3： | 6 |
| 14 | Acetyl-11-keto-β-boswellic acid suppresses docetaxel-resistant prostate cancer cells in vitro and in vivo by blocking Akt and Stat3 signaling,thus suppressing chemoresistant stem cell-like properties显示文摘Acquired docetaxel-resistance of prostate cancer (PCa) remains a clinical obstacle due to the lack of effective therapies. Acetyl-11- keto-β-boswellic acid (AKBA) is a pentacyclic triterpenic acid isolated from the fragrant gum resin of the Boswellia serrata tree, which has shown intriguing antitumor activity against human cell lines established from PCa, colon cancer, malignant glioma, and leukemia. In this study, we examined the effects of AKBA against docetaxel-resistant PCa in vitro and in vivo as well as its anticancer mechanisms. We showed that AKBA dose-dependently inhibited cell proliferation and induced cell apoptosis in docetaxel-resistant PC3/Doc cells;its IC50 value in anti-proliferation was ~17 μM. Furthermore, AKBA dose-dependently suppressed the chemoresistant stem cell-like properties of PC3/Doc cells, evidenced by significant decrease in the ability of mammosphere formation and down- regulated expression of a number of stemness-associated genes. The activation of Akt and Stat3 signaling pathways was remarkably enhanced in PC3/Doc cells, which contributed to their chemoresistant stem-like phenotype. AKBA (10–30 μM) dose- dependently suppressed the activation of Akt and Stat3 signaling pathways in PC3/Doc cells. In contrast, overexpression of Akt and Stat3 significantly attenuated the inhibition of AKBA on PC3/Doc cell proliferation. In docetaxel-resistant Pca homograft mice, treatment with AKBA significantly suppresses the growth of homograft RM-1/Doc, equivalent to its human PC3/Doc, but did not decrease their body weight. In summary, we demonstrate that AKBA inhibits the growth inhibition of docetaxel-resistant Pca cells in vitro and in vivo via blocking Akt and Stat3 signaling, thus suppressing their cancer stem cell-like properties. | Yong-qing Liu Shi-kang Wang Qing-qing Xu Hui-qing Yuan Yan-xia Guo Qian Wang Feng Kong Zhao-min Lin De-qing Sun Rong-mei Wang Hong-xiang Lou | 2019 | Acta Pharmacologica Sinica2019，40，5： | 6 |
| 15 | Effect of Surface Roughness on the Oxidation Behavior of a Directionally Solidified Ni-Based Superalloy at 1,100℃显示文摘The effect of surface roughness on the oxidation behavior of a directionally solidified Ni-based superalloy was investigated by surface mapping microscope,scanning electron microscope and X-ray diffraction.It was found that specimens with surface roughness of 0.05 urn exhibit the best oxidation resistance,while specimens with surface roughness of 0.14 μm behave worse than specimens with surface roughness of 0.83 μm.The specimens with surface roughness of 0.05 μm have the best oxidation resistance,which is mainly due to the smallest surface area exposed in air and thinnest work-hardening layer.The Al_2O_3 layer alleviates the oxidation process of the specimens with surface roughness of 0.83 μm,and this is the possible reason for the better oxidation resistance of samples with surface roughness of 0.83 μm than samples with surface roughness of 0.14 μm. | Li Wang Wei-Guo Jiang Xiang-Wei Li Jia-Sheng Dong Wei Zheng Hui Feng Lang-Hong Lou | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，3： | 6 |
| 16 | Emission of intermediate volatility organic compounds from a ship main engine burning heavy fuel oil显示文摘Intermediate volatility organic compounds(IVOCs)are crucial precursors of secondary organic aerosol(SOA).In this study,gaseous IVOCs emitted from a ship main engine burning heavy fuel oil(HFO)were investigated on a test bench,which could simulate the real-world operations and emissions of ocean-going ships.The chemical compositions,emission factors(EFs)and volatility distributions of IVOC emissions were investigated.The results showed that the main engine burning HFO emitted a large amount of IVOCs,with average IVOC EFs of 20.2-201 mg/kg-fuel.The IVOCs were mainly comprised of unspeciated compounds.The chemical compositions of exhaust IVOCs were different from that of HFO fuel,especially for polycyclic aromatic compounds and alkylcyclohexanes.The volatility distributions of IVOCs were also different between HFO exhausts and HFO fuel.The distinctions in IVOC emission characteristics between HFO exhausts and HFO fuel should be considered when assessing the IVOC emission and related SOA formation potentials from ocean-going ships burning HFO,especially when using fuel-surrogate models. | Haijun Lou Yuejiao Hao Weiwei Zhang Penghao Su Fan Zhang Yingjun Chen Daolun Feng Yifan Li | 2019 | Journal of Environmental Sciences2019，31，10： | 5 |

| 18 | LncRNA NEAT1 promotes colorectal cancer cell proliferation and migration via regulating glial cell-derived neurotrophic factor by sponging miR-196a-5p显示文摘Colorectal cancer (CRC)is the one of the most common malignant tumors worldwide.Recent years,widespread long non-coding RNAs (IncRNAs)have been discovered and are known to regulate gene expression in cancers.However,the roles and underlying mechanisms of IncRNA in CRC remain largely unclear.Here,we firstly revealed that repression of IncRNA nuclear paraspeckle assembly transcript 1 (NEAT1)inhibited cell proliferation and migration in HCT116.cells and overexpression of NEAT1 promoted cell proliferation and migration in SW480 cells using CCK8 assay and transwell assay.Then,we found that suppression of NEAT1 increased the miR- 196a-5p expression in HCT116 cells,while elevation of NEAT1 decreased the miR-196a-5p expression in SW480 cells using qPCR assay.Furthermore,miR-196a-5p could bind to the predicted binding site of NEAT1.We then found that miR-196a-5p was involved in the role of NEAT1 in CRCs.In addition,we demonstrated that miR-196a-Sp mimics inhibited the glial cell-derived neurotrophic factor (GDNF)expression in HCT116 cells and meanwhile,miR-196a-5p inhibitor promoted GDNF expression in SW480 cells using qPCR and western blot analysis.Then,we proved that miR-196a- 5p exerted its function via regulating GDNF expression in CRCs.Ultimately,our study demon- strated that NEAT1 exerted its role via miR-196a-5p/GDNF axis in CRCs.In summary,this work provided the first evidence of a NEAT1/miR-196a-5p/GDNF regulatory pathway in CRC. | Feng Zhong Wei Zhang Yang Cao Qian Wen Yue Cao Bidan Lou Jinxiang Li Wenying Shi Yinghan Liu Rong Luo and Cheng Chen | 2018 | Acta Biochimica et Biophysica Sinica2018，50，12： | 5 |
| 19 | Grade classification of neuroepithelial tumors using high-resolution magic-angle spinning proton nuclear magnetic resonance spectroscopy and pattern recognition显示文摘Clinical data have shown that survival rates vary considerably among brain tumor patients,according to the type and grade of the tumor.Metabolite profiles of intact tumor tissues measured with high-resolution magic-angle spinning proton nuclear magnetic resonance spectroscopy (HRMAS 1H NMRS) can provide important information on tumor biology and metabolism.These metabolic fingerprints can then be used for tumor classification and grading,with great potential value for tumor diagnosis.We studied the metabolic characteristics of 30 neuroepithelial tumor biopsies,including two astrocytomas (grade I),12 astrocytomas (grade II),eight anaplastic astrocytomas (grade III),three glioblastomas (grade IV) and five medulloblastomas (grade IV) from 30 patients using HRMAS 1H NMRS.The results were correlated with pathological features using multivariate data analysis,including principal component analysis (PCA).There were significant differences in the levels of N-acetyl-aspartate (NAA),creatine,myo-inositol,glycine and lactate between tumors of different grades (P<0.05).There were also significant differences in the ratios of NAA/creatine,lactate/creatine,myo-inositol/creatine,glycine/creatine,scyllo-inositol/creatine and alanine/creatine (P<0.05).A soft independent modeling of class analogy model produced a predictive accuracy of 87% for high-grade (grade III-IV) brain tumors with a sensitivity of 87% and a specificity of 93%.HRMAS 1H NMR spectroscopy in conjunction with pattern recognition thus provides a potentially useful tool for the rapid and accurate classification of human brain tumor grades. | CHEN WenXue LOU HaiYan ZHANG HongPing NIE Xiu LAN WenXian YANG YongXia XIANG Yun QI JianPin LEI Hao TANG HuiRu CHEN FenEr DENG Feng | 2011 | Science China(Life Sciences)2011，54，7： | 5 |
| 20 | Effect of Different Dietary Protein and Lipid Levels on the Growth,Body Composition,and Intestinal Digestive Enzyme Activities of Juvenile Yellow Drum Nibea albiflora(Richardson)显示文摘An 8-week feeding trial was conducted to determine the optimal dietary protein-to-lipid ratio for juvenile Nibea albiflora with an initial weight of(11.76 ± 0.20) g.Nine experimental diets containing different concentrations of protein(40%,47%,or 54%) and lipids(5%,9%,or 13%) in a 3 × 3 factorial experimental design were tested in triplicate groups of fish,while the protein-to-energy(P/E) ratios of the diets varied in the range of 19.74–28.32 mg k J^(-1).Results showed that fish fed diets containing 9% or 13% lipids with 54% protein exhibited significantly higher weight gains and specific growth rates than those fed other diets.The feed conversion rate of fish fed the diet with 40% protein and 5% lipids was significantly poorer than that of fish fed other diets.The protein efficiency rate of fish fed diets with 5% lipids was significantly lower than that of fish fed 9% or 13% lipid diets.Carcass lipid and energy contents were positively correlated with dietary lipid level regardless of protein level.Fish fed a 54% protein diet showed the highest trypsin activity.The intestinal lipase activity of fish fed the diet containing 13% lipids was significantly higher than that of fish fed 5% or 9% lipid diets.These results demonstrate the high protein dietary requirements of N.albiflora.A diet containing 54% protein and 9%–13% lipids with a P/E ratio of 26.2–27.81 mg protein k J^(-1) can be considered optimal for juvenile N.albiflora. | WANG Ligai HU Shenyu LOU Bao CHEN Dongxing ZHAN Wei CHEN Ruiyi LIU Feng XU Dongdong | 2018 | Journal of Ocean University of China2018，17，5： | 4 |
