3Nutritional evaluation of different cultivars of potatoes(Solanum tuberosum L.) from China by grey relational analysis(GRA) and its application in potato steamed bread making显示文摘Chemical composition(moisture,protein,starch,ash,fiber,fat),vitamins(vitamin C,vitamin B1,vitamin B2),total polyphenol content,antioxidant capacity,minerals,and amino acid of 14 potato cultivars in China were evaluated.The results indicated that all parameters varied significantly among different potato cultivars.The total starch,crude protein and fat content ranged between 57.42–67.83%,10.88–14.10% and 0.10–0.73% dry weight(DW),respectively.Moreover,the consumption of potato increased remarkably the dietary intake of vitamins,K,Mn and Cu.In addition,the chemical score of amino acid varied considerably between different cultivars,which ranged from 54(Neida 3 and Neida 41) to 71(Neida 34).Grey relational analysis(GRA) indicated that Neida 26 exhibited the most comprehensive nutritional values among potato cultivars,followed by Neida 42.Different potato flours had a significant effect on the quality parameters of potato steamed bread(PSB),Neida 26 and Neida 34 were more suitable for making PSB.ZHOU Liang MU Tai-hua MA Meng-mei ZHANG Ruo-fang SUN Qing-hua XU Yan-wen 2019Journal of Integrative Agriculture2019,18,1:21
4Soil Erosion Changes over the Past Five Decades in the Red Soil Region of Southern China显示文摘This paper reports the dynamic changes of soil and water loss in the red soil region of Southern China since the 1950s. The red soil region covers eight provinces: Jiangxi, Zhejiang, Fujian, Anhui, Hubei, Hunan, Guangdong and Hainan. From the 1950s to 1986, the annual rate of soil erosion increased by 3.4%. From 1986 to 1996 and from 1996 to 2000, the annual rates of soil erosion decreased by 2.0% and 0.32%, respectively. Field surveys showed that from 2000 to 2005, the area of soil and water loss decreased annually by 1.2%. This decrease was a result of large-scale erosion control activities across China. Although the eroded soil has been restored, the restoration process is very slow and full restoration will take a long time. Our report suggests that controlling soil and water loss is a challenging task, and additional measures must be taken to effectively control the soil erosion in the red soil region.LIANG Yin LI Decheng LU Xixi YANG Xuan PAN Xianzhang MU Huan SHI Deming ZHANG Bin 2010Journal of Mountain Science2010,7,1:18
5Astragaloside Ⅳ inhibits pathological functions of gastric cancer-associated fibroblasts显示文摘AIM To investigate the inhibitory effect of astragaloside IV on the pathological functions of cancer-associated fibroblasts,and to explore the underlying mechanism.METHODS Paired gastric normal fibroblast(GNF) and gastric cancer-associated fibroblast(GCAF) cultures were established from resected tissues. GCAFs were treated with vehicle control or different concentrations of astragaloside Ⅳ. Conditioned media were prepared from GNFs,GCAFs,control-treated GCAFs,and astragaloside Ⅳ-treated GCAFs,and used to culture BGC-823 human gastric cancer cells. Proliferation,migration and invasion capacities of BGC-823 cells were determined by MTT,wound healing,and Transwell invasion assays,respectively. The action mechanism of astragaloside Ⅳ was investigated by detecting the expression of micro RNAs and the expression and secretion of the oncogenic factor,macrophage colonystimulating factor(M-CSF),and the tumor suppressive factor,tissue inhibitor of metalloproteinase 2(TIMP2),in different groups of GCAFs. The expression of the oncogenic pluripotency factors SOX2 and NANOG in BGC-823 cells cultured with different conditioned media was also examined.RESULTS GCAFs displayed higher capacities to induce BGC-823 cell proliferation,migration,and invasion than GNFs(P < 0.01). Astragaloside Ⅳ treatment strongly inhibited the proliferation-,migration-and invasion-promoting capacities of GCAFs(P < 0.05 for 10 μmol/L,P < 0.01 for 20 μmol/L and 40 μmol/L). Compared with GNFs,GCAFs expressed a lower level of micro RNA-214(P < 0.01) and a higher level of micro RNA-301 a(P < 0.01). Astragaloside Ⅳ treatment significantly upregulated micro RNA-214 expression(P < 0.01) and down-regulated micro RNA-301 a expression(P < 0.01) in GCAFs. Reestablishing the micro RNA expression balance subsequently suppressed M-CSF production(P < 0.01) and secretion(P < 0.05),and elevated TIMP2 production(P < 0.01) and secretion(P < 0.05). Consequently,the ability of GCAFs to increase SOX2 and NANOG expression in BGC-823 cells was abolished by astragaloside Ⅳ.CONCLUSION Astragaloside Ⅳ can inhibit the pathological functions of GCAFs by correcting their dysregulation of micro RNA expression,and it is promisingly a potent therapeutic agent regulating tumor microenvironment.Zhen-Fei Wang Da-Guang Ma Zhe Zhu Yong-Ping Mu Yong-Yan Yang Li Feng Hao Yang Jun-Qing Liang Yong-Yan Liu Li Liu Hai-Wen Lu 2017World Journal of Gastroenterology2017,23,48:15
6Estrogen receptor alpha gene polymorphism associated with type 2 diabetes mellitus and the serum lipid concentration in Chinese women in Guangzhou显示文摘Background Estrogen might play an important role in type 2 diabetes mellitus pathogenesis. A number of polymorphisms have been reported in the estrogen receptor alpha (ERα) gene (also named ESR1), including the XbaI and PvuII restriction enzyme polymorphisms of ESR1, which may be involved in disease pathogenesis. The aim of this study was to determine whether ERα gene polymorphisms are associated with type 2 diabetes mellitus and serum lipid level. Methods Two hundred and ninety-nine patients with type 2 diabetes mellitus were compared with three hundred and forty-one health controls of Guangzhou in China, both were male and postmenopausal female residents at 51-70 years. ESR1 genotyping was performed using polymerase chain reaction (PCR) and PvuII and XbaI restriction fragment length polymorphism (PCR-RFLP) analysis. Results ESR1 allelic frequencies of P, p and X, x alleles were 0.408, 0.592; 0.360, 0.640 in the type 2 diabetes mellitus group and 0.318, 0.682; 0.328, 0.672 in the control group, respectively. In case-control study, there was significant difference in PvuII, but not XbaI, allele frequency between the type 2 diabetes mellitus and control groups (P=0.001 and P=0.122). When the group was separated into men and women, the difference was significant in women (P<0.001) but not in men (P=0.854) with the PvuII genotype, and the effect of PvuII variant on the development of type 2 diabetes mellitus was improved with aging. In addition, PvuII genotype was associated with blood glucose [fasting blood glucose (FBG), postprandial blood glucose (PBG)] and serum lipid [total cholesterol (TC) and low density lipoprotein (LDL)-c] concentration in healthy women. Conclusions PvuII polymorphism of ESR1 increases susceptibility to type 2 diabetes mellitus in Chinese Guangzhou women. ESR1 variants may also impact serum lipid metabolism, which might provide a mechanism connecting ESR1 to type 2 diabetes.HUANG Qin WANG Ting-huai LU Wen-sheng MU Pan-wei YANG Yan-fang LIANG Wei-wen LI Cai-xia LIN Gui-ping 2006Chinese Medical Journal2006,,21:14

10Modeling and Trajectory Tracking Control for Flapping-Wing Micro Aerial Vehicles显示文摘This paper studies the trajectory tracking problem of flapping-wing micro aerial vehicles(FWMAVs)in the longitudinal plane.First of all,the kinematics and dynamics of the FWMAV are established,wherein the aerodynamic force and torque generated by flapping wings and the tail wing are explicitly formulated with respect to the flapping frequency of the wings and the degree of tail wing inclination.To achieve autonomous tracking,an adaptive control scheme is proposed under the hierarchical framework.Specifically,a bounded position controller with hyperbolic tangent functions is designed to produce the desired aerodynamic force,and a pitch command is extracted from the designed position controller.Next,an adaptive attitude controller is designed to track the extracted pitch command,where a radial basis function neural network is introduced to approximate the unknown aerodynamic perturbation torque.Finally,the flapping frequency of the wings and the degree of tail wing inclination are calculated from the designed position and attitude controllers,respectively.In terms of Lyapunov's direct method,it is shown that the tracking errors are bounded and ultimately converge to a small neighborhood around the origin.Simulations are carried out to verify the effectiveness of the proposed control scheme.Wei He Xinxing Mu Liang Zhang Yao Zou 2021IEEE/CAA Journal of Automatica Sinica2021,8,1:10
11Preventing DC Over-voltage in Multi-terminal HVDC Transmission显示文摘This paper is concerned with power reduction control which is used to avoid DC over-voltage for multiterminal HVDC transmission of offshore wind power.Voltages and frequencies of offshore AC wind farm networks are used for transmitting control signals for the power reduction control.These methods do not require fast communication.Power reduction sharing among the offshore wind farms using the different control signals is analysed.The control systems are also compared against the DC chopper method to prevent a DC overvoltage.Simulation and experiments are carried out to evaluate the control systems.Oluwole D.Adeuyi Marc Cheah-Mane Jun Liang Luke Livermore Qing Mu 2015CSEE Journal of Power and Energy Systems2015,1,1:9

13Application of video-assisted thoracic surgery in the standard operation for thoracic tumors显示文摘Objective: To evaluate the short-term outcomes of video-assisted thoracic surgery (VATS) for thoracic tumors. Methods: The data of 1,790 consecutive patients were retrospectively reviewed. These patients underwent VATS pulmonary resections, VATS esophagectomies, and VATS resections of mediastinal tumors or biopsies at the Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and January 2012. Results: There were 33 patients converted to open thoracotomy (OT, 1.84%). The overall morbidity and mortality rate was 2.79% (50/1790) and 0.28% (5/1790), respectively. The overall hospitalization and chest tube duration were shorter in the VATS lobectomy group (n=949) than in the open thoracotomy (OT) lobectomy group (n=753). There were no significant differences in morbidity rate, mortality rate and operation time between the two groups. In the esophageal cancer patients, no significant difference was found in the number of nodal dissection, chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS esophagectomy group (n=81) and open esophagectomy group (n=81). However, the operation time was longer in the VATS esophagectomy group. In the thymoma patients, there was no significant difference in the chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS thymectomy group (n=41) and open thymectomy group (n=41). However, the operation time was longer in the VATS group. The median tumor size in the VATS thymectomy group was comparable with that in the OT group. Conclusions: In early-stage (I/II) non-small cell lung cancer patients who underwent lobectomies, VATS is comparable with the OT approach with similar short-term outcomes. In patients with resectable esophageal cancer, VATS esophagectomy is comparable with OT esophagectomy with similar morbidity and mortality. VATS thymectomy for Masaoka stage I and II thymoma is feasible and safe, and tumor size is not contraindicated. Longer follow-ups are needed to determine the oncologic equivalency of VATS lobectomy, esophagectomy, and thymectomy for thymoma vs. OT.Ju-Wei Mu Gui-Yu Chen Ke-Lin Sun Da-Wei Wang Bai-Hua Zhang Ning Li Fang Lv You-Sheng Mao Qi Xue Shu-Geng Gao Jun Zhao Da-Li Wang Zhi-Shan Li Wen-Dong Lei Yu-Shun Gao Liangze Zhang Jin-Feng Huang Kang Shao Kai Su Kun Yang Liang Zhao Fei-Yue Feng Yong-Gang Wang Jian Li Jie He 2013Cancer Biology & Medicine2013,10,1:8

15Ultrasound features of extranodal extension in the metastatic cervical lymph nodes of papillary thyroid cancer:a case-control study显示文摘Objective:Extranodal extension in cervical lymph nodes is an important risk factor for the progression and prognosis of papillary thyroid cancer.The purpose of this study was to identify the common and characteristic preoperative ultrasonography features that are associated with the pathologic extranodal extension of metastatic papillary thyroid carcinoma.Methods:We retrospectively assessed and compared clinicopathologic and ultrasound features between 60 papillary thyroid cancer patients with extranodal extension and 120 control patients with papillary thyroid cancer without extranodal extension.Results:With respect to the pathological N stage and clinicopathologic features,N1b stage papillary thyroid carcinomas were more frequently found in patients who were extranodal extension-positive,in comparison with those who were extranodal extension-negative(78.3%vs.63.3%,P=0.043).Extranodal extension was detected most frequently in level VI cervical lymph nodes(48.7%).In our univariate analysis of patients with papillary thyroid carcinoma,cervical lymph nodes with extranodal extension showed higher incidences of node matting,microcalcification,cystic area,aspect ratio<2,and larger diameter than those without extranodal extension(all P<0.05).Our multivariate analysis demonstrated that node matting and cystic area were independent risk factors for the presence of extranodal extension[odds ratio(OR):4.751,95%confidence interval(CI):1.212~18.626,P=0.025;OR:2.707,95%CI:1.127~6.502,P=0.026].Conclusions:Common ultrasound features may indicate the presence of extranodal extension in patients with metastatic cervical lymph nodes of papillary thyroid carcinoma.Jiali Mu Xiaofeng Liang Fangxuan Li Juntian Liu Sheng Zhang Jing Tian 2018Cancer Biology & Medicine2018,15,2:7
16The Relationship between Polymorphisms at 17 Gene Sites and Hypertension among the Aboriginal Tibetan People显示文摘Objective The incidence of hypertension in Tibet ranks highest among all Chinese provinces. This may be due to genetic changes caused by Tibet's unique natural environment and agrarian lifestyle, prompting us to investigated the relationship between gene polymorphisms and hypertension. Methods Blood samples were collected from 229 hypertensive participants and 372 healthy (control) participants from five Tibetan counties. Seventeen single nucleotide polymorphisms were investigated for their connection to hypertension. Results The C allele at rs2070744 of the NOS3 gene was shown to be significantly associated with hypertension (P=0.0443; OR=1.636). Additionally, the T allele of rs4961 of the ADD gene was correlated with hypertension in women (P=0.03124; OR=1.584). Conclusion In this study we found that the NOS3 and ADD genes were related to a high incidence of hypertension among Tibetans. NOS3 gene plays a role in regulating vascular tone and blood vessel diameter, which may be altered by the low-oxygen environment of Tibet. ADD is involved in water and salt metabolism, which is consistent with the high-salt diet of Tibetans. The correlations elucidated by our study were different from those of other ethnic groups, indicating that these findings may be specific to the Tibetan people.LI Kui LIANG Yu SUN Yin ZHANG Ling Xia YI Xin CHEN Yong GU SANG LA MU WANG Jian 2012Biomedical and Environmental Sciences2012,25,5:6
17Dynamic Expression of MicroRNA-127 During Porcine Prenatal and Postnatal Skeletal Muscle Development显示文摘MicroRNAs(miRNAs), evolutionarily conserved non-coding RNAs in length 21-24 bp, play a critical role in skeletal muscle development. In this study, to explore the function of mircoRNA-127 in porcine skeletal muscle development, eight tissue samples from adult pigs and longissimus muscle samples at 26 developmental stages were collected from Tongcheng and Landrace pigs. The spatial-temporal expression profiles of miRNA-127 were carried out using step-loop quantitative real-time PCR(stemloop RT-PCR). To explore the molecular functions of miRNA-127, we predicted its target genes and performed functional annotation using bioinformatics methods. Results suggested that miRNA-127 was abundantly expressed in heart, ovary, uterus and spleen tissues and was weakly expressed in liver, lung, kidney and small intestine in both Tongcheng and Landrace pigs. And miRNA-127 showed significant expression differences in heart, ovary, spleen and uterus tissues between these two breeds. miRNA-127 basically kept at a relatively stable high level in middle and later embryonic stages and a low expression level in early embryonic stages and postnatal stages, but the expression levels of miRNA-127 were higher in Tongcheng pigs than in Landrace at most developmental stages. miRNA-127 potentially regulated 240 candidate genes. Results of Gene Ontology and KEGG pathway analysis indicated that these genes could be involved in many molecular functions and mechanisms, such as regulation of the force of heart contraction, regulation of transcription, regulation of T cell differentiation, MAPK signaling pathway and GnRH signaling pathway. Many significantly enriched GO terms and KEGG pathways were related to skeletal muscle development. This study will be helpful to understand the biological function for miRNA-127 and identify candidate gene associated with meat production traits in pigs.YANG Ya-lan LI Yan LIANG Ru-yi ZHOU Rong AO Hong MU Yu-lian YANG Shu-lin LI Kui TANG Zhong-lin 2014Journal of Integrative Agriculture2014,13,6:6
18Ambient levels of atmospheric carbonyls in Beijing during the 2008 Olympic Games显示文摘The measurements of atmospheric carbonyls concentrations in Beijing were conducted from 12 July to 8 October, 2008, covering the periods of the 2008 Olympic Games and Paralympic Games. Six carbonyls, including formaldehyde, acetaldehyde, acetone, butyraldehyde, valeraldehyde, and hexaldehyde, were identified in all air samples. The total average concentrations of these carbonyls before, during, and after traffic restriction were (48.1 ± 15.2), (36.6 ± 14.5) and (23.4 ± 12.3) μg/m3, respectively. Compared with the period after traffic restriction, the distinct high concentrations of the carbonyls before and during traffic restriction were primarily ascribed to the remarkable contribution of photochemical reactions. With respect to our previous investigation in the summer of 2005, the reductions of formaldehyde, acetaldehyde and acetone during traffic restriction period were about 64%, 47% and 27%, respectively, indicating that the air cleaning actions adopted by the Chinese government for the two games were efficient. The lowest levels of atmospheric carbonyls and the extremely high composition proportion of acetone after the traffic restriction were mainly attributed to the long-term effect of the control measures for the two games.Zhu Xu Junfeng Liu Yujie Zhang Peng Liang Yujing Mu 2010Journal of Environmental Sciences2010,22,9:6
19Mapping Quantitative Trait Loci Associated with Photoperiod Sensitivity in Maize(Zea mays L.)显示文摘Photoperiod sensitivity in maize plays an essential role in utilizing tropic and sub-tropic germplasm to temperate areas.This study aims to identify and map the QTLs responsible for the characteristics measuring photoperiod sensitivity,days from planting to silking(SD),photoperiod response coefficient of silking(PRC),and anthesis-silking interval(ASI).Using the population derived from Zheng 58,photoperiod-insensitive parent,and Ya 8701,photoperiod-sensitive parent,a linkage map was constructed with 93 single sequence repeat(SSR) markers.Phenotyping of 296 F2:3 families of the population in replicated-field test was conducted in both long-day(Beijing,China) and short-day(Sichuan,China) conditions.Ten QTLs were identified to be associated with the SD and ASI on chromosomes 3,4,6,8,and 10 in the long-day conditions,and 11 QTLs were detected to be related to the SD and ASI on chromosomes 2,3,4,5,6,8,and 10 in the short-day conditions,respectively.A QTL associated with the PRC as a major effect in the long-day conditions located in the same position as the QTL related to the SD and ASI in the map,and was on chromosome 10 linked with marker bnlg1655.Using these QTLs in the marker-assisted selection,the photoperiod sensibility could be reduced by selection of the alleles responsible for the SD,PRC,and ASI in breeding programs.MU Gui-qin LIANG Yan ZHANG Zhi-ming WU Yuan-qi LIU Shi-jian PENG Hua ZHANG Su-zhi PANGuang-tang 2009Agricultural Sciences in China2009,8,1:6
20Effects of lifestyle interventions on rural patients with type 2 diabetes mellitus显示文摘BACKGROUND The prevalence of type 2 diabetes mellitus(T2DM)is rising rapidly in rural areas,and lifestyle interventions can effectively reduce the blood glucose levels of patients with T2DM.However,current dietary and exercise guidelines are still at experimental stages and are difficult for subjects to understand and implement.The Human Metabolism Analyzer provides real life interventions for the prevention and treatment of T2DM,and our pilot research has demonstrated its effectiveness and good compliance.AIM To investigate the effect of and compliance with lifestyle interventions in rural patients with T2DM.METHODS A total of ten rural villages were randomly selected in Chaoshui Township,Penglai City,Shandong Province,China,to conduct health screening among residents aged 50 years or older.Each rural village represented a group,and 12 patients with T2DM were randomly selected from each group(total:120)to participate in this study and receive real life lifestyle interventions and medication guidance.Lifestyle interventions included changing the meal order(A),postprandial activities(B),resistance exercise(C),and reverse abdominal breathing(D).Diabetes education was conducted at least once a month with a weekly phone follow-up to monitor exercise and diet.Waist circumference,blood pressure,body mass index(BMI),motor function,body composition,fasting blood glucose,and glycated hemoglobin(HbA1c)were analyzed before and 3 mo after the intervention.Moreover,patient compliance and adjustments of hypoglycemic drugs were evaluated.RESULTS A total of 109 subjects completed the study.The compliance rates for lifestyle interventions A,B,C,and D were 57.79%,60.55%,64.22%,and 75.23%,respectively.Among the subjects who received hypoglycemic drugs,the dose was reduced 2 to 3 times based on blood glucose in 54(67.50%)subjects and was tapered and discontinued in 5(6.25%)subjects within 3 mo,with no significant fluctuations in blood glucose after dose reduction and withdrawal.After lifestyle interventions,waist circumference,BMI,fasting blood glucose,and HbA1c significantly decreased(P<0.001);motor function and body composition also significantly improved(P<0.001).CONCLUSION For patients with T2DM,compliance to real-life lifestyle interventions is good,and the interventions significantly improve metabolic indicators such as waist circumference,BMI,blood pressure,HbA1c,body composition,and motor function.Some patients are able to taper or discontinue hypoglycemic drugs.Bo Wang Xiao-Li Mu Juan Zhao Hai-Ping Jiang Shan-Shan Li Ge Yan Ying-Ying Hua Xue-Yi Ren Li-Xia Xing Yan Liang Shu-Dong Zhang Yu-Chi Zhao 2020World Journal of Diabetes2020,11,6:5
