1Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases.Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang 2020Genomics, Proteomics & Bioinformatics2020,18,6:29
2Numerical modeling of tidal currents,sediment transport and morphological evolution in Hangzhou Bay,China显示文摘A 2D depth-averaged numerical model is set up to simulate the macro-scale hydrodynamic characteristics,sediment transport patterns and morphological evolution in Hangzhou Bay,a large macro-tidal estuary on the eastern coast of China.By incorporating the shallow water equations,the suspended sediment transport equation and the mass-balance equation for sediment;short-term hydrodynamics,sediment transport and long-term morphological evolution for Hangzhou Bay are simulated and the underlying physical mechanisms are analyzed.The model reproduces the spatial distribution patterns of suspended sediment concentration(SSC) in Hangzhou Bay,characterized by three high SSC zones and two low SSC zones.It also correctly simulates the residual flow,the residual sediment transport and the sediment accumulation patterns in Hangzhou Bay.The model results are in agreement with previous studies based on field measurements.The residual flow and the residual sediment transport are landwards directed in the northern part of the bay and seawards directed in the southern part.Sediment accumulation takes place in most areas of the bay.Harmonic analysis revealed that the tide is flood-dominant in the northern part of the bay and ebb-dominant in the southern part of the bay.The strength of the flood-dominance increases landwards along the northern Hangzhoii Bay.In turn sediment transport in Hangzhou Bay is controlled by this tidal asymmetry pattern.In addition,the direction of tidal propagation in the East China Sea,the presence of the archipelago in the southeast and the funnel-shaped geometry of the bay,play important roles for the patterns of sediment transport and sediment accumulation respectively.Dong-feng XIE Shu GAO Zheng-bing WANG Cun-hong PAN 2013International Journal of Sediment Research2013,28,3:23
3Assessment of left ventricular systolic synchronicity by real-time three-dimensional echocardiography in patients with dilated cardiomyopathy显示文摘Background Recent advances in real-time three-dimensional echocardiography (RT3DE) offer the potential to assess the left ventricular (LV) dyssynchrony simultaneously by analyzing the 17 segments time-volume curves. The purpose of this study was to test the feasibility and accuracy of RT3DE for quantitative evaluation of left ventricular systolic synchronicity. Methods Twenty-four patients with dilated cardiomyopathy (DCM) and twenty-five healthy volunteers were enrolled in this study. Full volume RT3DE was performed by using Philips IE33 with X3-1 probe. The global and 17-segmental time-volume curves were obtained by the on-line Qlab software (version 4.2). The time to minimal systolic volume in each segment (Tmsv) was taken to derive the following indexes of systolic asynchrony: Tmsv 16-SD, Tmsv 16-Dif, Tmsv 12-SD, Tmsv 12-Dif, Tmsv 6-SD and Tmsv 6-Dif, which meant the standard deviation or the maximal difference of Tmsv among the 16, 12 and 6 segments of the left ventricle respectively. The software also provided with each of the above parameters as a percentage of the cardiac cycle. Results Tmsv 16-SD, Tmsv 12-SD and Tmsv 6-SD were all significantly larger in the DCM group than those of the control group [Tmsv 16-SD: (52.9±40.6) ms vs (8.8±6.2) ms; Tmsv 12-SD: (29.5±30.8) ms vs (6.9±4.0) ms; Tmsv 6-SD: (28.9±34.6) ms vs (7.0±4.7) ms, all P≤0.001]. Tmsv 16-Dif, Tmsv 12-Dif and Tmsv 6-Dif were also significantly larger in the DCM group. There were close negative relations between the LVEF determined by RT3DE and each of the indexes of systolic asynchrony, among which the indexes of Tmsv-16-SD% and Tmsv-16-Dif% correlated most closely (r=-0.703 and r =-0.701, respectively). The DCM patients had significantly larger EDV and ESV, with significantly reduced LVEF compared with the healthy subjects. Conclusion RT3DE provides a simple, useful and unique approach to assess the systolic synchronicity of all the left ventricular segments simultaneously.ZENG Xin SHU Xian-hong PAN Cui-zhen CHEN Rui-zhen CHENG Kuan LIU Shi-zhen CHEN Hao-zhu 2006Chinese Medical Journal2006,,11:16

6Antioxidant and cardioprotective effects of Ilex cornuta on myocardial ischemia injury显示文摘Previous studies have indicated that the Ilex genus exhibits antioxidant, neuroprotective, hepatoprotective, and antiinflammatory activities. However, the pharmacologic action and mechanisms of Ilex cornuta against cardiac diseases have not yet been explored. The present study was designed to investigate the antioxidant and cardioprotective effects of Ilex cornuta root with in vitro and in vivo models. The anti-oxidative effects of the extract of Ilex cornuta root(ICR) were measured by 2, 2-diphenyl-1- picrylhydrazyl(DPPH) free-radical scavenging and MTT assays as well as immunoassay. Furthermore, a rat model of myocardial ischemia was established to investigate the cardioprotective effect of ICR in vivo. Eight compounds were isolated and identified from ICR and exhibited DPPH free-radical scavenging activities. They also could increase cell viability and inhibit morphological changes induced by H_2O_2 or Na_2S_2O_4 in H9c2 cardiomyocytes, followed by increasing the SOD activities and decreasing the MDA and ROS levels. In addition, it could suppress the apoptosis of cardiomyocytes. In the rat model of myocardial ischemia, ICR decreased myocardial infarct size and suppressed the activities of LDH and CK. Furthermore, ICR attenuated histopathological alterations of heart tissues and the MDA levels, while increasing SOD activities in serum. In conclusion, these results suggest that ICR has cardioprotective activity and could be developed as a new food supplement for the prevention of ischemic heart disease.YUAN Yan PAN Shu YANG Shi-Lin LIU Yan-Li XU Qiong-Ming 2017Chinese Journal of Natural Medicines2017,15,2:13

9Modification on the tribological properties of ceramics lubricated by water using fullerenol as a lubricating additive显示文摘It is necessary to modify the running-in process for the application of ceramics using water as a lubricant in real conditions because ceramics sliding in water are characterized by a running-in period with severe friction and wear.Fullerenol,a kind of highly water-soluble nanoparticle,was synthesized and then used to ameliorate the tribological properties of Si 3 N 4 sliding against Al 2 O 3 in pure water.With the addition of fullerenol,the running-in period was shortened from 30 min to 100 s at a speed of 250 mm/s.The speed threshold above which ultralow friction can be obtained in a short time was expanded from 450 mm/s to 80 mm/s.Meanwhile,the load-carrying ability of water film was increased.The role of fullerenol was discussed based on observation of the wear scar by an optical interferometer and XPS characterization of the tribo-film on the wear track.LIU YuHong WANG XiaoKang LIU PengXiao ZHENG JunPeng SHU ChunYing PAN GuoShun LUO JianBin 2012Science China(Technological Sciences)2012,55,9:9
10浆液 M2-pyruvate kinase : 为屏蔽的 colorectal 癌症质量的有希望的非侵略的 biomarker显示文摘 AIM: To explore the value of serum M2-pyruvate kinase (M2-PK) in colorectal cancer (CRC) mass screening. METHODS: We conducted a molecular epidemiology study in Hangzhou, China, from year 2006 to year 2008. Serum samples were collected from 93 CRC, 41 advanced adenomas, 137 adenomas, 47 non-adenomatous polyps, and 158 normal participants in a community setting. Serum M2-PK and carcinoembryonic antigen (CEA) were measured using Enzyme-linked immuno-sorbent assay. SPSS 16.0 software was used to perform data analysis. Area under the receiver operating characteristic curve (AUC), sensitivity, and specificities were estimated for serum M2-PK in diagnosis of colorectal lesions and compared with CEA. RESULTS: Average serum M2-PK value among 158 normal people was 2.96 U/mL and not affected by gender (P = 0.47) or age (P = 0.59). Average serum M2-PK (U/mL) was 14.75 among stage Ⅲ and 13.10 among stage Ⅰ and Ⅱ CRC patients, about 4 times higher than that among normal people. Average serum M2-PK was 8.58, 6.70, 5.13 and 2.51 U/mL among advanced adenoma, adenomas, non-adenomatous polyps, and inflammatory bowel disease patients, respectively. AUC for serum M2-PK was greater than that for CEA among all colorectal lesions. AUC for serum M2-PK was 0.89 (0.84, 0.94) (95% confidence interval), higher than that for CEA [0.70 (0.62-0.79)] in CRC stageⅠ and Ⅱ, 0.89 (0.84-0.94) vs 0.73 (0.63-0.83) in CRC stage Ⅲ, 0.81 (0.74-0.86) vs 0.63 (0.53 -0.73) in advanced adeno- mas, 0.69 (0.64-0.76) vs 0.54 (0.47-0.60) in adenomas, and 0.69 (0.62-0.78) vs 0.58 (0.48-0.68) in nonadenomatous polyps. The diagnostic sensitivity for all colorectal lesions increased with decrease in the cut-off value of serum M2-PK. The diagnostic sensitivity (%) of serum M2-PK was 100.00 for CRC, 95.12 advanced ad- enoma, 82.48 adenoma, and 82.98 non-adenomatous polyp. There were no CRC cases missed and 40.51% of unnecessary colonoscopies were avoided when the cut-off value was 2.00 U/mL. CONCLUSION: Serum M2-PK can be used as a primary screening test in CRC mass screening. It may be a promising non-invasive biomarker for CRC early detection.Wen Meng Hong-Hong Zhu Ze-Feng Xu Shan-Rong Cai Qi Dong Qiang-Rong Pan Shu Zheng Su-Zhan Zhang 2012World Journal of Gastrointestinal Oncology2012,4,6:9

14Influence of chronic HBV infection on superimposed acute hepatitis E显示文摘AIM:To investigate the influence of chronic hepatitis B virus(HBV)infection[based on the status of hepatitis B e antigen(HBeAg),HBV DNA,and cirrhosis]on superimposed acute hepatitis E.METHODS:A total of 294 patients were recruited from the Department of Infectious Diseases of the Third Affiliated Hospital,Sun Yat-sen University,from January 2003 to January 2012.The patients were classified into two groups:an HBV+hepatitis E virus(HEV)group(a group with chronic HBV infection that was superinfected with acute hepatitis E,n=118)and an HEV group(a group with acute hepatitis E,n=176).We retrospectively analyzed and compared the clinical features of the two groups.Statistical analyses were performed using theχ2test or Fisher’s exact test for categorical variables and the Student’s t test forcontinuous variables.A P value<0.05 was considered statistically significant.RESULTS:The peak values of prothrombin time,serum total bilirubin,and Model for End-Stage Liver Disease scores were significantly higher in the HBV+HEV group.More patients in the HBV+HEV group had complications(39.8%vs 16.5%,P=0.000)and developed liver failure(35.6%vs 8.5%,P=0.000).Additionally,the mortality of the HBV+HEV group was significantly higher(20.3%vs 7.4%,P=0.002).Further analysis of the HBV+HEV group showed that there were no significant differences in complication occurrence,liver failure incidence,or mortality between patients with different HBeAg and HBV DNA statuses.However,in patients with underlying cirrhosis,complication occurrence and liver failure incidence significantly increased.In total,12.7%of the patients in the HBV+HEV group received anti-HBV treatment,but this therapy failed to reduce mortality in patients who developed liver failure.CONCLUSION:The presence of underlying cirrhosis in chronic HBV infection results in more severe clinical outcomes with superimposed acute hepatitis E.AntiHBV treatment cannot improve the prognosis of liver failure caused by HBV-HEV superinfection.Si-Hong Cheng Li Mai Feng-Qin Zhu Xing-Fei Pan Hai-Xia Sun Hong Cao Xin Shu Wei-Min Ke Gang Li Qi-Huan Xu 2013World Journal of Gastroenterology2013,19,35:8

16Vitamin B12 modulates Parkinson’s disease LRRK2 kinase activity through allosteric regulation and confers neuroprotection显示文摘Missense mutations in Leucine-Rich Repeat Kinase 2(LRRK2)cause the majority of familial and some sporadic forms of Parkinson’s disease(PD).The hyperactivity of LRRK2 kinase induced by the pathogenic mutations underlies neurotoxicity,promoting the development of LRRK2 kinase inhibitors as therapeutics.Many potent and specific small-molecule LRRK2 inhibitors have been reported with promise.However,nearly all inhibitors are ATP competitive—some with unwanted side effects and unclear clinical outcome—alternative types of LRRK2 inhibitors are lacking.Herein we identify 5′-deoxyadenosylcobalamin(AdoCbl),a physiological form of the essential micronutrient vitamin B12 as a mixed-type allosteric inhibitor of LRRK2 kinase activity.Multiple assays show that AdoCbl directly binds LRRK2,leading to the alterations of protein conformation and ATP binding in LRRK2.STD-NMR analysis of a LRRK2 homologous kinase reveals the contact sites in AdoCbl that interface with the kinase domain.Furthermore,we provide evidence that AdoCbl modulates LRRK2 activity through disrupting LRRK2 dimerization.Treatment with AdoCbl inhibits LRRK2 kinase activity in cultured cells and brain tissue,and prevents neurotoxicity in cultured primary rodent neurons as well as in transgenic C.elegans and D.melanogaster expressing LRRK2 disease variants.Finally,AdoCbl alleviates deficits in dopamine release sustainability caused by LRRK2 disease variants in mouse models.Our study uncovers vitamin B12 as a novel class of LRRK2 kinase modulator with a distinct mechanism,which can be harnessed to develop new LRRK2-based PD therapeutics in the future.Adam Schaffner Xianting Li Yacob Gomez-Llorente Emmanouela Leandrou Anna Memou Nicolina Clemente Chen Yao Farinaz Afsari Lianteng Zhi Nina Pan Keita Morohashi Xiaoluan Hua Ming-Ming Zhou Chunyu Wang Hui Zhang Shu G.Chen Christopher J.Elliott Hardy Rideout Iban Ubarretxena-Belandia Zhenyu Yue 2019Cell Research2019,29,4:7

18Influence of Ce on Characteristics of Inclusions and Microstructure of Pure Iron显示文摘The experiments on adding Ce,Mn and S to molten iron have been carried out by means of the electric furnace,and the concentration of oxygen,the evolution of inclusions and microstructures of samples are analyzed,indicating that the concentration of dissolved oxygen decreases greatly after adding Ce. The calculated thermodynamics results at 1273 K performed on Factsage show that Ce2O2S and CeAlO3 are formed with the increase of Ce content for w(Ce)>0.0002 and w(S)<0.0001,while three cerium sulphides (CeS,Ce3S4 and Ce2S3,in sequence),MnS and Ce2O2S are formed with the increase of S content and the decrease of Ce content for w(Ce)>0.0002 and w(S)>0.0001. These results are consistent with the SEM observations. Finally,some possible reasons are given to explain the formation of intragranular ferrite in the pure iron.WEN Bin SONG Bo PAN Ning SHU Qi-feng HU Xiao-jun MAO Jing-hong 2011Journal of Iron and Steel Research(International)2011,18,2:7
