1Influence of potato flour on dough rheological properties and quality of steamed bread显示文摘It is a novel idea to make steamed bread by adding potato flour into wheat flour considering the production and nutritional factors of potato. In this study, the influence of potato flour(0–35%) on dough rheology and quality of steamed bread were investigated. Potato flour addition significantly influenced the dough rheological properties and steamed bread quality, such as increased water absorption, the maximum gaseous release height, total volume of CO_2 and hardness, while decreased dough stability and specific volume of steamed bread. Moreover, correlation analysis suggested that dough height at the maximum development time, dough stability, water absorption and the phase tangent can be used for predicting the technological quality of steamed bread. Potato-wheat steamed bread had higher dietary fibre, ash content and antioxidant activity than those of wheat steamed bread. The estimated glycemic index decreased from 73.63(0%) to 60.01(35%). Considering the sensory evaluation, the steamed bread with 20% potato flour is acceptable. In conclusion, adding appropriate quantity of potato flour to wheat flour for steamed bread production will not only maintain the technological quality, but also can improve the nutritional value of the steamed bread.LIU Xing-li MU Tai-hua SUN Hong-nan ZHANG Miao CHEN Jing-wang 2016Journal of Integrative Agriculture2016,15,11:51
2Ligustrazine monomer against cerebral ischemia/reperfusion injury显示文摘Ligustrazine(2,3,5,6-tetramethylpyrazine) is a major active ingredient of the Szechwan lovage rhizome and is extensively used in treatment of ischemic cerebrovascular disease.The mechanism of action of ligustrazine use against ischemic cerebrovascular diseases remains unclear at present.This study summarizes its protective effect,the optimum time window of administration,and the most effective mode of administration for clinical treatment of cerebral ischemia/reperfusion injury.We examine the effects of ligustrazine on suppressing excitatory amino acid release,promoting migration,differentiation and proliferation of endogenous neural stem cells.We also looked at its effects on angiogenesis and how it inhibits thrombosis,the inflammatory response,and apoptosis after cerebral ischemia.We consider that ligustrazine gives noticeable protection from cerebral ischemia/reperfusion injury.The time window of ligustrazine administration is limited.The protective effect and time window of a series of derivative monomers of ligustrazine such as 2-[(1,1-dimethylethyl)oxidoimino]methyl]-3,5,6-trimethylpyrazine,CXC137 and CXC195 after cerebral ischemia were better than ligustrazine.Hai-jun Gao Peng-fei Liu Pei-wen Li Zhuo-yan Huang Feng-bo Yu Ting Lei Yong Chen Ye Cheng Qing-chun Mu Hai-yan Huang 2015Neural Regeneration Research2015,10,5:48
3De novo characterization of the root transcriptome of a traditional Chinese medicinal plant Polygonum cuspidatum显示文摘Various active components have been extracted from the root of Polygonum cuspidatum.However,the genetic basis for their activity is virtually unknown.In this study,25600002 short reads (2.3 Gb) of P.cuspidatum root transcriptome were obtained via Illumina HiSeq 2000 sequencing.A total of 86418 unigenes were assembled de novo and annotated.Twelve,18,60 and 54 unigenes were respectively mapped to the mevalonic acid (MVA),methyl-D-erythritol 4-phosphate (MEP),shikimate and resveratrol biosynthesis pathways,suggesting that they are involved in the biosynthesis of pharmaceutically important anthraquinone and resveratrol.Eighteen potential UDP-glycosyltransferase unigenes were identified as the candidates most likely to be involved in the biosynthesis of glycosides of secondary metabolites.Identification of relevant genes could be important in eventually increasing the yields of the medicinally useful constituents of the P.cuspidatum root.From the previously published transcriptome data of 19 non-model plant taxa,1127 shared orthologs were identified and characterized.This information will be very useful for future functional,phylogenetic and evolutionary studies of these plants.HAO DaCheng MA Pei MU Jun CHEN ShiLin XIAO PeiGen PENG Yong HUO Li XU LiJia SUN Chao 2012Science China(Life Sciences)2012,55,5:36
4Spatio-temporal dynamics of vegetation and its relationship with climate factors Mongolia, China coverage in Inner显示文摘The vegetation coverage dynamics and its relationship with climate factors on different spatial and temporal scales in Inner Mongolia during 2001-2010 were analyzed based on MODIS-NDVI data and climate data.The results indicated that vegetation coverage in Inner Mongolia showed obvious longitudinal zonality,increasing from west to east across the region with a change rate of 0.2/10°N.During 2001-2010,the mean vegetation coverage was 0.57,0.4 and 0.16 in forest,grassland and desert biome,respectively,exhibiting evident spatial heterogeneities.Totally,vegetation coverage had a slight increasing trend during the study period.Across Inner Mongolia,the area of which the vegetation coverage showed extremely significant and significant increase accounted for 11.25% and 29.13% of the area of whole region,respectively,while the area of which the vegetation coverage showed extremely significant and significant decrease accounted for 7.65% and 26.61%,respectively.On inter-annual time scale,precipitation was the dominant driving force of vegetation coverage for the whole region.On inter-monthly scale,the change of vegetation coverage was consistent with both the change of temperature and precipitation,implying that the vegetation growth within a year is more sensitive to the combined effects of water and heat rather than either single climate factor.The vegetation coverage in forest biome was mainly driven by temperature on both inter-annual and inter-monthly scales,while that in desert biome was mainly influenced by precipitation on both the two temporal scales.In grassland biome,the yearly vegetation coverage had a better correlation with precipitation,while the monthly vegetation coverage was influenced by both temperature and precipitation.In grassland biome,the impacts of precipitation on monthly vegetation coverage showed time-delay effects.MU Shaojie YANG Hongfei LI Jianlong CHEN Yizhao GANG Chengcheng ZHOU Wei JU Weimin 2013Journal of Geographical Sciences2013,23,2:28
5Effects of early enteral nutrition on Th17/Treg cells and IL-23/IL-17 in septic patients显示文摘BACKGROUND The imbalance of Th17/Treg cells and the IL-23/IL-17 axis have been confirmed to be associated with sepsis and various inflammatory diseases. Early enteral nutrition (EEN) can modulate the inflammatory response, improve immune dysfunction, and prevent enterogenic infection in critically ill patients;however, the precise mechanisms remain unclear. Considering the important roles of Th17 and Treg lymphocytes in the development of inflammatory and infectious diseases, we hypothesized that EEN could improve the immune dysfunction in sepsis by maintaining a balanced Th17/Treg cell ratio and by regulating the IL- 23/IL-17 axis. AIM To investigate the effects of EEN on the Th17/Treg cell ratios and the IL-23/IL-17 axis in septic patients. METHODS In this prospective clinical trial, patients were randomly divided into an EEN or delayed enteral nutrition (DEN) group. Enteral feeding was started within 48 h in the EEN group, whereas enteral feeding was started on the 4th day in the DEN group. The Th17 and Treg cell percentages and the interleukin levels were tested on days 1, 3, and 7 after admission. The clinical severity and outcome variables were also recorded. RESULTS Fifty-three patients were enrolled in this trial from October 2017 to June 2018. The Th17 cell percentages, Th17/Treg cell ratios, IL-17, IL-23, and IL-6 levels of the EEN group were lower than those of the DEN group on the 7th day after admission (P < 0.05). The duration of mechanical ventilation and of the intensive care unit stay of the EEN group were shorter than those of the DEN group (P <0.05). However, no difference in the 28-d mortality was found between the two groups (P = 0.728). CONCLUSION EEN could regulate the imbalance of Th17/Treg cell ratios and suppress the IL- 23/IL-17 axis during sepsis. Moreover, EEN could reduce the clinical severity of sepsis but did not reduce the 28-d mortality of septic patients.Jia-Kui Sun Wen-Hao Zhang Wen-Xiu Chen Xiang Wang Xin-Wei Mu 2019World Journal of Gastroenterology2019,25,22:27
6Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background:As a large,prospective,multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF),the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score(COSSH-ACLFs),has been approved by some foreign scholars;however,its predictive value needs to be verified.This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.Methods:This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014.Spearman method was used to assess the correlation of COSSHACLFs with classical scores.Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF,and stratified analysis was used to further verify the stability of this relationship.We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve(AUROC)and Z-test.Results:A total of 975 patients with HBV-ACLF were screened,and 751 were analyzed(623 male and 128 female).COSSH-ACLFs was the highest in patients with end-stage ACLF,followed by those with middle-and early-stage ACLF(H=211.8,P<0.001).In the fully adjusted model,COX multivariate regression analysis revealed that COSSH-ACLFs(as a continuous variable)was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days(hazard ratio[HR]:1.37[1.22,1.53],P<0.001)and 90 days(HR:1.43[1.29,1.58],P<0.001).The same trend could be observed in the crude model and minimally adjusted model.The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792,respectively,indicating a stronger predictive accuracy than those of classic models.Conclusions:COSSH-ACLFs,with a superior predictive accuracy compared with other classical scores,can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.Jing-Jing Tong Wei Zhao Xiu-Ying Mu Xiang Xu Hai-Bin Su Xiao-Yan Liu Jing Chen Xing-Ran Zhai Yu Wang Jin-Hua Hu 2019Chinese Medical Journal2019,,13:27

10Target observations for improving initialization of high-impact ocean-atmospheric environmental events forecasting显示文摘In this paper, we emphasize the importance of accurate initial conditions in predicting high-impact ocean-atmospheric environmental events, such as El Nin?o-Southern Oscillation(ENSO), Indian Ocean Dipole(IOD), tropical cyclone(TC), and Kuroshio large meander(KLM), by reviewing recent progresses toward target observations for improving the initialization of these events forecasting. Since ield observations are costly and will never be dense enough to fully cover the vast space of these events, it is necessary to develop methodologies that guide the design of eicient and efective observation strategy. Of particular interest is a method called conditional non-linear optimal perturbation(CNOP), which has been shown to be very useful in determining the sensitive areas for target observations applicable to the predictions of ENSO, IOD, TC, and KLM. Further studies are needed to understand the predictability of these events under the inluence of climate change, and to explore the possibility of implementing ield programs of target observations. hese studies are challenging but are crucially important for improving our forecast skill of the high-impact ocean-atmospheric environmental events, and thus for disaster prevention,climate change mitigation, and sustainable socio-economic development.Mu Mu Wansuo Duan Dake Chen Weidong Yu 2015National Science Review2015,2,2:21

12Alkaline Intrusives at the East Foot of the Taihang-Da Hinggan Mountains:Chronology,Sr,Nd and Pb Isotopic Characteristics and Their Implications显示文摘Based on the Rb-Sr isochron dating results, this paper suggests that the alkaline intrusive belt at the east foot of the Taihang-Da Hinggan Mountains were formed between 135 and 122 Ma. And the alkaline intrusives in the north and south sections of this belt have entirely different Sr, Nd and Pb isotopic characteristics, i.e., all the rocks in the south section have positive εSr(t) and negative εNd(t) values and all those in the north have the opposite values. On the εSr(t) versus εNd(t) correlation diagram, the samples from the south are concentrated along the enriched mantle evolution trend lines and nearby, while those from the north fall along the depleted mantle trend lines and nearby. On the Pb isotope composition diagram, most of the samples from the south section fall on the mantle Pb evolution line and nearby, while those from the north lie between the Pb evolution lines of the mantle and the erogenic belt. The above-stated isotopic characteristics not only indicate that the source rocksYAN Guohan XU Baoliang MU Baolei WANG Guanyu CHANG Zhaoshan CHEN Tingli ZHAO Yongchao WANG Xiaofang ZHANG Renhu QIAO Guangsheng CHU Zhuyin 2000Acta Geologica Sinica(English Edition)2000,74,4:18

16Gastrodin inhibits neuroinflammation in rotenone-induced Parkinson's disease model rats显示文摘The present study showed that the latency of rats moving on a vertical grid was significantly prolonged,and the number of rats sliding down from the declined plane was increased remarkably,in rotenone-induced Parkinson's disease model rats compared with control rats.The moving latency recovered to normal levels,but the number of slides was significantly increased at 28 days after model establishment.The slope test is a meaningful approach to evaluate the symptoms of Parkinson's disease model rats treated with rotenone.In addition,loss of substantia nigral dopaminergic neurons in model rats was observed at 1 day after the model was established,and continued gradually at 14 and 28 days.The expression of tyrosine hydroxylase-positive cells was significantly increased in gastrodin-treated rats at 14 days.Significant numbers of activated microglia cells were observed in model rats at 14 and 28 days;treatment of rats with Madopar at 28 days suppressed microglial activation.Treatment of rats with gastrodin or Madopar at 28 days significantly reduced interleukin-1β expression.The loss of substantia nigral dopaminergic neurons paralleled the microglial activation in Parkinson's disease model rats treated with rotenone.The inflammatory factors tumor necrosis factor-α and interleukin-1β are involved in the substantia nigral damage.Gastrodin could protect dopaminergic neurons via inhibition of interleukin-1β expression and neuroinflammation in the substantia nigra.Chun Li Xin Chen Nan Zhang Yangwen Song Yang Mu 2012Neural Regeneration Research2012,7,5:15

18Application of deep eutectic solvents in biomass pretreatment and conversion显示文摘Biomass is renewable, abundant, cheap, biocompatible, and biodegradable materials and has been used to produce chemicals, materials,energy, and fuels. However, most of the biomass, especially most of the biomass polymers are not soluble in common solvents, which hinders their pretreatment and conversion. Deep eutectic solvents(DESs) are environmental-friendly, cheap, and highly tunable, with high solubility,which renders them potential applications in biomass pretreatment and conversion. They could be used as solvents or catalysts and so on. This paper intends to review the application of DESs for the pretreatment of biomass and conversion of biomass to value-added products. We focus on the following topics related to biomass and DESs:(1) DESs for the pretreatment of biomass;(2) DESs for the dissolution and separation of biomass or extraction of chemicals from biomass;(3) DESs for biomass conversion;(4) Drawbacks, and recyclability of DESs for pretreatment and conversion of biomass.Yu Chen Tiancheng Mu 2019Green Energy & Environment2019,4,2:15
19Genetic polymorphisms of ADH2 and ALDH2 association with esophageal cancer risk in southwest China显示文摘AIM: To evaluate the impact of alcohol dehydrogenase 2 (ADH2) and aldehyde dehydrogenase 2 (ALDH2) polymorphisms on esophageal cancer risk. METHODS: One hundred and ninety-one esophageal cancer patients and 198 healthy controls from Yanting County were enrolled in this study. ADH2 and ALDH2 genotypes were examined by polymerase-chain-reaction with the confronting-two-pair-primer (PCR-CTPP) method. Unconditional logistic regression was used to calculate the odds ratios (OR) and 95% confidence interval (95% CI). RESULTS: Both ADH2*1 allele and ALDH2*1/*2 allele showed an increased risk of developing esophageal cancer. The adjusted OR (95% CI) for ADH2*1 allele compared with ADH2*2/*2 was 1.65 (95% CI = 1.02-2.68) and 1.67 (95% CI = 1.02-2.72) for ALDH2*1/*2 compared with ALDH2*1/*1. A significant interaction between ALDH2 and drinking was detected regarding esophageal cancer risk, the OR was 1.83 (95% CI = 1.13-2.95). Furthermore, when compared with ADH2*2/*2 and ALDH2*1/*1 carriers, ADH2*1 and ALDH2*2 carriers showed an elevated risk of developing esophageal cancer among non-alcohol drinkers (OR = 2.46, 95% CI = 0.98-6.14), and a significantly elevated risk of developing esophageal cancer among alcohol drinkers among alcohol drinkers (OR = 9.86, 95% CI = 3.10-31.38). CONCLUSION: ADH2 and ALDH2 genotypes are associated with esophageal cancer risk. ADH2*1 allele and ALDH2*2 allele carriers have a much higher risk of developing esophageal cancer, especially among alcohol drinkers.Shu-Juan Yang Hua-Yu Wang Xiao-Qing Li Hui-Zhang Du Can-Jie Zheng Huai-Gong Chen Xiao-Yan Mu Chun-Xia Yang 2007World Journal of Gastroenterology2007,13,43:14
20Anatomy and influence of the splenic artery in laparoscopic spleen-preserving splenic lymphadenectomy显示文摘AIM: To investigate the splenic hilar vascular anatomy and the influence of splenic artery(Sp A) type in laparoscopic total gastrectomy with spleen-preserving splenic lymphadenectomy(LTGSPL).METHODS:The clinical anatomy data of 317 patients with upper- or middle-third gastric cancer who underwent LTGSPL in our hospital from January 2011 to December 2013 were collected. The patients were divided into two groups(concentrated group vs distributed group) according to the distance between the splenic artery's furcation and the splenic hilar region. Then, the anatomical layout, clinicopathologic characteristics, intraoperative variables, and postoperative variables were compared between the two groups.RESULTS: There were 205 patients with a concentrated type(64.7%) and 112 patients with a distributed type(35.3%) Sp A. There were 22 patients(6.9%) with a single branch of the splenic lobar vessels, 250(78.9%) with 2 branches, 43(13.6%) with 3 branches, and 2 patients(0.6%) with multiple branches. Eighty sevenpatients(27.4%) had type?Ⅰ?splenic artery trunk, 211(66.6%) had type Ⅱ, 13(4.1%) had type Ⅲ, and 6(1.9%) had type Ⅳ. The mean splenic hilar lymphadenectomy time(23.15 ± 8.02 vs 26.21 ± 8.84 min; P = 0.002), mean blood loss resulting from splenic hilar lymphadenectomy(14.78 ± 11.09 vs 17.37 ± 10.62 m L; P = 0.044), and number of vascular clamps used at the splenic hilum(9.64 ± 2.88 vs 10.40 ± 3.57; P = 0.040) were significantly lower in the concentrated group than in the distributed group. However, the mean total surgical time, mean total blood loss, and the mean number of harvested splenic hilar lymph nodes were similar in both groups(P > 0.05 for each comparison). There were also no significant differences in clinicopathological and postoperative characteristics between the groups(P > 0.05).CONCLUSION: It is of value for surgeons to know the splenic hilar vascular anatomy when performing LTGSPL. Patients with concentrated type Sp A may be optimal patients for training new surgeons.Chao-Hui Zheng Mu Xu Chang-Ming Huang Ping Li Jian-Wei Xie Jia-Bin Wang Jian-Xian Lin Jun Lu Qi-Yue Chen Long-Long Cao Mi Lin 2015World Journal of Gastroenterology2015,21,27:14
