| 1 | Functional and morphological changes of the gut barrier during the restitution process after hemorrhagic shock显示文摘AIM: To investigate the functional, morphological changes of the gut barrier during the restitution process after hemorrhagic shock, and the regional differences of the large intestine and small intestine in response to ischemia/reperfusion injury.METHODS: Forty-seven Sprague-Dawley rats with body weight of 250-300 g were divided into two groups: control group (sham shock n = 5) and experimental group (n = 42).Experimental group was further divided into six groups (n = 7 each) according to different time points after the hemorrhagic shock, including 0th h group, 1st h group, 3rd h group, 6th h group, 12th h group and 24th h group. All the rats were gavaged with 2 mL of suspension of lactulose (L) (100 mg/2 mL) and mannitol (M) (50 mg/each) at the beginning and then an experimental rat model of hemorrhagic shock was set up. The specimens from jejunum, ileum and colon tissues and the blood samples from the portal vein were taken at 0, 1, 3, 6, 12 and 24 h after shock resuscitation, respectively. The morphological changes of the intestinal mucosa, including the histology of intestinal mucosa, the thickness of mucosa, the height of villi, the index of mucosal damage and the numbers of goblet cells, were determined by light microscope and/or electron microscope. The concentrations of the bacterial endotoxin lipopolysaccharides (LPS) from the portal vein blood, which reflected the gut barrier function, were examined by using Limulus test. At the same time point,to evaluate intestinal permeability, all urine was collected and the concentrations of the metabolically inactive markers such as L and M in urine were measured by using GC-9A gas chromatographic instrument.RESULTS: After the hemorrhagic shock, the mucosal epithelial injury was obvious in small intestine even at the 0th h, and it became more serious at the 1st and the 3rd h. The tissue restitution was also found after 3 h,though the injury was still serious. Most of the injured mucosal restitution was established after 6 h and completed in 24 h. Two distinct models of cell deathapoptosis and necrosis-were involved in the destruction of rat intestinal epithelial cells. The number of goblet cells on intestinal mucosa was reduced significantly from 0 to 24 h (the number from 243±13 to 157±9 for ileum, 310±19 to 248±18 for colon; r = -0.910 and -0.437 respectively,all P<0.001), which was the same with the large intestine, but the grade of injury was lighter with the values of mucosal damage index in 3 h for jejunum,ileum, and colon being 2.8, 2.6, 1.2, respectively. The mucosal thickness and the height of villi in jejunum and ileum diminished in 1 h (the average height decreased from 309±24 to 204±23 μm and 271±31 to 231±28 μm,r = -0.758 and -0.659, all P<0.001; the thickness from 547±23 to 418±28 μm and 483±45 to 364±35 μm, r= -0.898 and -0.829, all P<0.001), but there was no statistical difference in the colon (F= 0.296, P = 0.934). Compared with control group, the urine L/M ratio and the blood LPS concentration in the experimental groups raised significantly,reaching the peak in 3-6 h (L/M: control vs 3 h vs 6 h was 0.029±0.09 vs 0.063±0.012 vs 0.078±0.021, r=-0.786,P<0.001; LPS: control vs 3 h vs6 h was 0.09±0.021 vs 0.063±0.012 vs 0.25±0.023, r= -0.623, P<0.001), and it kept increasing in 24 h.CONCLUSION: The gut barrier of the rats was seriously damaged at the early phase of ischemic reperfusion injury after hemorrhagic shock, which included the injury and atrophy in intestinal mucosa and the increasing of intestinal permeability. Simultaneously, the intestinal mucosa also showed its great repairing potentiality, such as the improvement of the intestinal permeability and the recovery of the morphology at different phases after ischemic repeffusion injury. The restitution of gut barrier function was obviously slower than that of the morphology and there was no direct correlation between them.Compared with the small intestine, the large intestine had stronger potentiality against injury. The reduction of the amount of intestinal goblet cells by injury did not influence the ability of intestinal mucosal restitution at a certain extent and it appeared to be intimately involved in the restitution of the epithelium. | Jian-Xing Chang Shuang Chen Li-Ping Ma Long-Yuan Jiang Jian-Wen Chen Rui-Ming Chang Li-Qiang Wen Wei Wu Zhi-Peng Jiang Zi-Tong Huang | 2005 | World Journal of Gastroenterology2005,11,35: | 44 |
| 2 | Astragalus polysaccharide enhances immunity and inhibits H9N2 avian influenza virus in vitro and in vivo显示文摘This study investigated the humoral immunization of Astragalus polysaccharide(APS) against H9N2 avian influenza virus(H9N2 AIV) infection in chickens. The effects of APS treatment on H9N2 infection was evaluated by an MTT [3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide] assay and analysis of MHC and cytokine mRNA expression. The effect on lymphocyte and serum antibody titers in vivo was also investigated. IL-4, IL-6, IL-10, LITAF, IL-12 and antibody titers to H9N2 AIV were enhanced in the first week after APS treatment. The results indicated that APS treatment reduces H9N2 AIV replication and promotes early humoral immune responses in young chickens. | Sanpha Kallon Xiaorong Li Jun Ji Cuiying Chen Qianyun Xi Shuang Chang Chunyi Xue Jingyun Ma Qingmei Xie Youngliang Zhang | 2013 | Journal of Animal Science and Biotechnology2013,4,4: | 48 |
| 3 | Baicalin prevents LPS-induced activation of TLR4/NF-κB p65 pathway and inflammation in mice via inhibiting the expression of CD14显示文摘Previous studies have shown that baicalin,an active ingredient of the Chinese traditional medicine Huangqin,attenuates LPS-induced inflammation by inhibiting the activation of TLR4/NF-κBp65 pathway,but how it affects this pathway is unknown.It has been shown that CD14 binds directly to LPS and plays an important role in sensitizing the cells to minute quantities of LPS via chaperoning LPS molecules to the TLR4/MD-2 signaling complex.In the present study we investigated the role of CD14 in the anti-inflammatory effects of baicalin in vitro and in vivo.Exposure to LPS(1μg/mL)induced inflammatory responses in RAW264.7 cells,evidenced by marked increases in the expression of MHC II molecules and the secretion of NO and IL-6,and by activation of MyD88/NF-κB p65 signaling pathway,as well as the expression of CD14 and TLR4.These changes were dose-dependently attenuated by pretreatment baicalin(12.5–50μM),but not by baicalin post-treatment.In RAW264.7 cells without LPS stimulation,baicalin dose-dependently inhibit the protein and mRNA expression of CD14,but not TLR4.In RAW264.7 cells with CD14 knockdown,baicalin pretreatment did not prevent inflammatory responses and activation of MyD88/NF-κB p65 pathway induced by high concentrations(1000μg/mL)of LPS.Furthermore,baicalin pretreatment also inhibited the expression of CD14 and activation of MyD88/NF-κB p65 pathway in LPS-induced hepatocyte-derived HepG2 cells and intestinal epithelial-derived HT-29 cells.In mice with intraperitoneal injection of LPS and in DSS-induced UC mice,oral administration of baicalin exerted protective effects by inhibition of CD14 expression and inflammation.Taken together,we demonstrate that baicalin pretreatment prevents LPS-induced inflammation in RAW264.7 cells in CD14-dependent manner.This study supports the therapeutic use of baicalin in preventing the progression of LPS-induced inflammatory diseases. | Ya-jun Fu Bo Xu Shao-wei Huang Xia Luo Xiang-liang Deng Shuang Luo Chang Liu Qing Wang Jin-yan Chen Lian Zhou | 2021 | Acta Pharmacologica Sinica2021,42,1: | 31 |
| 4 | Tooth regeneration: a revolution in stomatology and evolution in regenerative medicine显示文摘A tooth is a complex biological organ and consists of multiple tissues including the enamel, dentin, cementum and pulp. Tooth loss is the most common organ failure. Can a tooth be regenerated? Can adult stem cells be orchestrated to regenerate tooth structures such as the enamel, dentin, cementum and dental pulp, or even an entire tooth? If not, what are the therapeutically viable sources of stem cells for tooth regeneration? Do stem cells necessarily need to be taken out of the body, and manipulated ex vivo before they are transplanted for tooth regeneration? How can regenerated teeth be economically competitive with dental implants? Would it be possible to make regenerated teeth affordable by a large segment of the population worldwide? This review article explores existing and visionary approaches that address some of the above-mentioned questions. Tooth regeneration represents a revolution in stomatology as a shift in the paradigm from repair to regeneration: repair is by metal or artificial materials whereas regeneration is by biological restoration. Tooth regeneration is an extension of the concepts in the broad field of regenerative medicine to restore a tissue defect to its original form and function by biological substitutes. | Sibel Yildirim Susan Y.

| 6 | Atorvastatin activates autophagy and promotes neurological function recovery after spinal cord injury显示文摘Atorvastatin, a lipid-lowering medication, provides neuroprotective effects, although the precise mechanisms of action remain unclear. Our previous studies confirmed activated autophagy following spinal cord injury, which was conducive to recovery of neurological functions. We hypothesized that atorvastatin could also activate autophagy after spinal cord injury, and subsequently improve recovery of neurological functions. A rat model of spinal cord injury was established based on the Allen method. Atorvastatin(5 mg/kg) was intraperitoneally injected at 1 and 2 days after spinal cord injury. At 7 days post-injury, western blot assay, reverse transcription-polymerase chain reaction, and terminal deoxynucleotidyl transferase-mediated dU TP nick-end labeling(TUNEL) staining results showed increased Beclin-1 and light chain 3B gene and protein expressions in the spinal cord injury + atorvastatin group. Additionally, caspase-9 and caspase-3 expression was decreased, and the number of TUNEL-positive cells was reduced. Compared with the spinal cord injury + saline group, Basso, Beattie, and Bresnahan locomotor rating scale scores significantly increased in the spinal cord injury + atorvastatin group at 14–42 days post-injury. These findings suggest that atorvastatin activated autophagy after spinal cord injury, inhibited apoptosis, and promoted recovery of neurological function. | Shuang Gao Zhong-ming Zhang Zhao-liang Shen Kai Gao Liang Chang Yue Guo Zhuo Li Wei Wang Ai-mei Wang | 2016 | Neural Regeneration Research2016,11,6: | 9 |

| 8 | Genetic aberration in primary hepatocellular carcinoma:correlation between p53 gene mutation and loss-of-heterozygosity on chromosome 16q21-q23 and 9p21-p23显示文摘To elucidate the molecular pathology underlying the development of hepatocellular carcinoma (HCC), we used 41 highly polymorphic microsatellite markers to examine 55 HCC and corresponding non-tumor liver tissues on chromosome 9, 16 and 17. Loss-of-heterozygosity (LOH) is observed with high frequency on chromosomal region 17p13 (36/55, 65%), 9p21-p23 (28/55, 51%), 16q21-q23 (27/55, 49%) in tumors. Meanwhile, microsatellite instability is rarely found in these microsatellite loci. Direct sequencing was performed to detect the tentative mutation of tumor suppressor genes in these regions: p53, MTS1/p16, and CDH1/E-cadherin. Within exon 5-9 of p53 gene, 14 out of 55 HCC specimens (24%) have somatic mutations, and nucleotide deletion of this gene is reported in HCC for the first time. Mutation in MTS1/pl6 is found only in one tumor case. We do not find mutations in CDH1/E-cadherin. Furthermore, a statistically significant correlation is present between p53 gene mutation and loss of chromosome region 16q21q23 and 9p21-p23, which indicates that synergism between p53 inactivation and deletion of 16q21-q23 and 9p21-p23 may play a role in the pathogenesis of HCC.

| 9 | Current understanding concerning intestinal stem cells显示文摘In mammals, the intestinal epithelium is a tissue that contains two distinct pools of stem cells: active intestinal stem cells and reserve intestinal stem cells. The former are located in the crypt basement membrane and are responsible for maintaining epithelial homeostasis under intact conditions, whereas the latter exhibit the capacity to facilitate epithelial regeneration after injury. These two pools of cells can convert into each other, maintaining their quantitative balance. In terms of the active intestinal stem cells, their development into functional epithelium is precisely controlled by the following signaling pathways: Wnt/β-catenin, Ras/Raf/Mek/Erk/MAPK, Notch and BMP/Smad. However, mutations in some of the key regulator genes associated with these signaling pathways, such as APC, Kras and Smad4, are also highly associated with gut malformations. At this point, clarifying the biological characteristics of intestinal stem cells will increase the feasibility of preventing or treating some intestinal diseases, such as colorectal cancer. Moreover, as preclinical data demonstrate the therapeutic effects of colon stem cells on murine models of experimental colitis, the prospects of stem cell-based regenerative treatments for ulcerous lesions in the gastrointestinal tract will be improved all the same. | Shuang Cui Peng-Yu Chang | 2016 | World Journal of Gastroenterology2016,22,31: | 6 |
| 10 | Development and utilization of a new chemically-induced soybean library with a high mutation density显示文摘Mutagenized populations have provided important materials for introducing variation and identifying gene function in plants. In this study, an ethyl methanesulfonate(EMS)-induced soybean(Glycine max) population,consisting of 21,600 independent M_2 lines, was developed.Over 1,000 M_(4(5))families, with diverse abnormal phenotypes for seed composition, seed shape, plant morphology and maturity that are stably expressed across different environments and generations were identified. Phenotypic analysis of the population led to the identification of a yellow pigmentation mutant, gyl, that displayed significantly decreased chlorophyll(Chl) content and abnormal chloroplast development. Sequence analysis showed that gyl is allelic to Minn Gold, where a different single nucleotide polymorphism variation in the Mg-chelatase subunit gene(ChlI1a) results in golden yellow leaves. A cleaved amplified polymorphic sequence marker was developed and may be applied to marker-assisted selection for the golden yellow phenotype in soybean breeding. We show that the newly developed soybean EMS mutant population has potential for functional genomics research and genetic improvement in soybean. | Zhongfeng Li Lingxue Jiang Yansong Ma Zhongyan Wei Huilong Hong Zhangxiong Liu Jinhui Lei Ying Liu Rongxia Guan Yong Guo Longguo Jin Lijuan Zhang Yinghui Li Yulong Ren Wei He Ming Liu Nang Myint Phyu Sin Htwe Lin Liu Bingfu Guo Jian Song Bing Tan Guifeng Liu Maiquan Li Xianli Zhang Bo Liu Xuehui Shi Sining Han Sunan Hua Fulai Zhou Lili Yu Yanfei Li Shuang Wang Jun Wang Ruzhen Chang Lijuan Qiu | 2017 | Journal of Integrative Plant Biology2017,59,1: | 6 |
| 11 | A Scan of Obesogenic Environments and a Spatial Inference of Obesity Prevalence in Chinese Children and Adolescents: Based on the Chinese Health and Nutrition Survey 2011 Data显示文摘Objective To identify the characteristics of Chinese obesogenic environments at a provincial level, infer a spatial distribution map of obesity prevalence in 31 provinces, and provide a foundation for development of policy to reduce obesity in children and adolescents. Methods After scanning obesity data on subjects aged 7-17 years from 12 provinces in the China Health and Nutrition Survey 2011 and environmental data on 31 provinces from the China Statistical Yearbook 2011 and other sources, we selected 12 predictors. We used the 12 surveyed provinces as a training sample to fit an analytical model with partial least squares regression and prioritized the 12 predictors using variable importance in projection. We also fitted a predictive model with Bayesian analysis. Results We identified characteristics of obesogenic environments. We fitted the predictive model with a deviance information criterion of 61.96 and with statistically significant(P < 0.05) parameter estimates of intercept [95% confidence interval(CI): 329.10, 963.11], log(oil)(CI: 13.11, 20.30), log(GDP)(CI: 3.05, 6.93), log(media)(CI:-234.95,-89.61), and log(washing-machine)(CI: 0.92, 5.07). The total inferred average obesity prevalence among those aged 7-17 was 9.69% in 31 Chinese provinces in 2011. We also found obvious clustering in occurrences of obesity in northern and eastern provinces in the predicted map. Conclusion Given complexity of obesity in children and adolescents, concerted efforts are needed to reduce consumption of edible oils, increase consumption of vegetables, and strengthen nutrition, health, and physical activity education in Chinese schools. The northern and eastern regions are the key areas requiring intervention. | GUO Chun Lei ZHANG Bing WANG Hui Jun FENG Guo Shuang LI Jun Ming SU Chang ZHANG Ji Guo WANG Zhi Hong DU Wen Wen | 2018 | Biomedical and Environmental Sciences2018,31,10: | 6 |
| 12 | MicroRNA-135a in ABCA1-labeled Exosome is a Serum Biomarker Candidate for Alzheimer’s Disease显示文摘Objective In the present study,the ABCA1 was used as a label to capture specific exosomes,the level of ABCA1-labeled exosomal microRNA-135 a(miR-135 a)was evaluated for the diagnosis of Alzheimer’s disease(AD),especially in patients with early stages of AD.Methods This is a preliminary research focused on the levels of ABCA1 in WBCs,RBCs,HT-22 cells,and neuron cells.The diagnostic value of ABCA1-labeled exosomal miR-135 a was examined using the CSF and serum of APP/PS1 double transgenic mice,and 152 patients with SCD,131 patients with MCI,198 patients with DAT,and 30 control subjects.Results The level of ABCA1 exosomes harvested from HT-22 cells and neuron culture medium was significantly higher compared to that of RBCs and WBCs(P<0.05).The levels of ABCA1-labeled exosomal miR-135 a increased in the CSF of MCI and DAT group compared to those of control group(P<0.05),slightly increased(P>0.05)in the serum of SCD patient group,and significantly increased in MCI and DAT patient groups compared to those of the control group(P<0.05).Conclusion This study outlines a method to capture specific exosomes and detect them using immunological methods,which is more efficient for early diagnosis of AD. | LIU Chen Geng MENG Shuang LI Ying LU Yao ZHAO Yue WANG Pei Chang | 2021 | Biomedical and Environmental Sciences2021,34,1: | 5 |
| 13 | Altered Local Field Potential Relationship Between the Parafascicular Thalamic Nucleus and Dorsal Striatum in Hemiparkinsonian Rats显示文摘The thalamostriatal pathway is implicated in Parkinson's disease(PD); however, PD-related changes in the relationship between oscillatory activity in the centromedian-parafascicular complex(CM/Pf, or the Pf in rodents) and the dorsal striatum(DS) remain unclear.Therefore, we simultaneously recorded local field potentials(LFPs) in both the Pf and DS of hemiparkinsonian and control rats during epochs of rest or treadmill walking. The dopamine-lesioned rats showed increased LFP power in the beta band(12 Hz–35 Hz) in the Pf and DS during both epochs, but decreased LFP power in the delta(0.5 Hz–3 Hz) band in the Pf during rest epochs and in the DS during both epochs, compared to control rats. In addition,exaggerated low gamma(35 Hz–70 Hz) oscillations after dopamine loss were restricted to the Pf regardless of the behavioral state. Furthermore, enhanced synchronization of LFP oscillations was found between the Pf and DS after the dopamine lesion. Significant increases occurred in the mean coherence in both theta(3 Hz–7 Hz) and beta bands,and a significant increase was also noted in the phase coherence in the beta band between the Pf and DS during rest epochs. During the treadmill walking epochs, significant increases were found in both the alpha(7 Hz–12 Hz)and beta bands for two coherence measures. Collectively,dramatic changes in the relative LFP power and coherence in the thalamostriatal pathway may underlie the dysfunction of the basal ganglia-thalamocortical network circuits in PD, contributing to some of the motor and non-motor symptoms of the disease. | Haiyan Zhang Jing Yang Xuenan Wang Xiaomeng Yao Hongyu Han Yunfeng Gao Hongli Chang Tianyu Xiang Shuang Sun Yanan Wang Xiusong Wang Min Wang | 2019 | Neuroscience Bulletin2019,35,2: | 5 |
| 14 | Seg-CapNet:A Capsule-Based Neural Network for the Segmentation of Left Ventricle from Cardiac Magnetic Resonance Imaging显示文摘Deep neural networks(DNNs)have been extensively studied in medical image segmentation.However,existing DNNs often need to train shape models for each object to be segmented,which may yield results that violate cardiac anatomical structure when segmenting cardiac magnetic resonance imaging(MRI).In this paper,we propose a capsulebased neural network,named Seg-CapNet,to model multiple regions simultaneously within a single training process.The Seg-CapNet model consists of the encoder and the decoder.The encoder transforms the input image into feature vectors that represent objects to be segmented by convolutional layers,capsule layers,and fully-connected layers.And the decoder transforms the feature vectors into segmentation masks by up-sampling.Feature maps of each down-sampling layer in the encoder are connected to the corresponding up-sampling layers,which are conducive to the backpropagation of the model.The output vectors of Seg-CapNet contain low-level image features such as grayscale and texture,as well as semantic features including the position and size of the objects,which is beneficial for improving the segmentation accuracy.The proposed model is validated on the open dataset of the Automated Cardiac Diagnosis Challenge 2017(ACDC 2017)and the Sunnybrook Cardiac Magnetic Resonance Imaging(MRI)segmentation challenge.Experimental results show that the mean Dice coefficient of Seg-CapNet is increased by 4.7%and the average Hausdorff distance is reduced by 22%.The proposed model also reduces the model parameters and improves the training speed while obtaining the accurate segmentation of multiple regions. | Yang-Jie Cao Shuang Wu Chang Liu Nan Lin Yuan Wang Cong Yang Jie Li | 2021 | Journal of Computer Science & Technology2021,36,2: | 3 |

| 16 | Current management of chemotherapy-induced neutropenia in adults:key points and new challenges显示文摘Chemotherapy-induced neutropenia(CIN)is a potentially fatal and common complication in myelosuppressive chemotherapy.The timing and grade of CIN may play prognostic and predictive roles in cancer therapy.CIN is associated with older age,poor functional and nutritional status,the presence of significant comorbidities,the type of cancer,previous chemotherapy cycles,the stage of the disease,specific chemotherapy regimens,and combined therapies.There are many key points and new challenges in the management of CIN in adults including:(1)Genetic risk factors to evaluate the patient’s risk for CIN remain unclear.However,these risk factors urgently need to be identified.(2)Febrile neutropenia(FN)remains one of the most common reasons for oncological emergency.No consensus nomogram for FN risk assessment has been established.(3)Different assessment tools[e.g.,Multinational Association for Supportive Care in Cancer(MASCC),the Clinical Index of Stable Febrile Neutropenia(CISNE)score model,and other tools]have been suggested to help stratify the risk of complications in patients with FN.However,current tools have limitations.The CISNE score model is useful to support decision-making,especially for patients with stable FN.(4)There are still some challenges,including the benefits of granulocyte colony stimulating factor treatment and the optimal antibiotic regimen in emergency management of FN.In view of the current reports,our group discusses the key points,new challenges,and management of CIN. | Committee of Neoplastic Supportive-Care(CONS),China Anti-Cancer Association Committee of Clinical Chemotherapy,China Anti-Cancer Association Yi Ba Yuankai Shi Wenqi Jiang Jifeng Feng Ying Cheng Li Xiao Qingyuan Zhang Wensheng Qiu Binghe Xu Ruihua Xu Bo Shen Zhiguo Luo Xiaodong Xie Jianhua Chang Mengzhao Wang Yufu Li Yuerong Shuang Zuoxing Niu Bo Liu Jun Zhang Li Zhang Herui Yao Conghua Xie Huiqiang Huang Wangjun Liao Gongyan Chen Xiaotian Zhang Hanxiang An Yanhong Deng Ping Gong Jianping Xiong Qinghua Yao Xin An Cheng Chen Yanxia Shi Jialei Wang Xiaohua Wang Zhiqiang Wang Puyuan Xing Sheng Yang Chenfei Zhou | 2020 | Cancer Biology & Medicine2020,17,4: | 2 |
| 17 | Association of Catalase Genotype with Oxidative Stress in the Predication of Colorectal Cancer:Modification by Epidemiological Factors显示文摘Objective This paper aims to assess the interaction between common variations in catalase(CAT) polymorphic gene and environmental factors for antioxidant defense enzyme in modulating individual susceptibility to colorectal cancer(CRC).Methods A case-control study with 880 colorectal cancer cases and 848 controls was conducted to investigate whether variations in the catalase(CAT) gene,one of the genes involved in scavenging oxidative stress,influenced susceptibility to CRC.Results The interaction between life style and genotypes as well as with their effects on colorectal cancer was deduced from the present study.Significant difference(P=0.01) was identified in the distribution of CAT genotype between the colorectal cancer cases and the controls.The CRC cases had significantly lower mean activity than the controls(P<0.01).Correlation analyses revealed statistically significant correlations between CAT activity and CAT genotype(P<0.01).Conclusion The risk of CRC was associated with smoking,low vegetable consumption,high pork and poultry consumptions,and low or high BMI.This is the first study reporting an association of polymorphism CAT-21A>T with colorectal cancer.Low CAT activity was associated with an increased risk of CRC;however,no evidence was found to support an association between CAT-21A>T polymorphism and CRC risk. | CHANG Dong HU Zhang Liang ZHANG Lin ZHAO Ya Shuang MENG Qing Hui GUAN Qing Bai ZHOU Jin PAN Hong Zhi | 2012 | Biomedical and Environmental Sciences2012,25,2: | 2 |

| 19 | Adaptive Operator-Based Spectral Deconvolution With the Levenberg-Marquardt Algorithm显示文摘Spectral distortion often occurs in spectral data due to the influence of the bandpass function of the spectrometer.Spectral deconvolution is an effective restoration method to solve this problem.Based on the theory of the maximum posteriori estimation,this paper transforms the spectral deconvolution problem into a multi-parameter optimization problem,and a novel spectral deconvolution method is proposed on the basis of Levenberg-Marquardt algorithm.Furthermore,a spectral adaptive operator is added to the method,which improves the effect of the regularization term.The proposed methods,Richardson-Lucy(R-L)method and Huber-Markov spectroscopic semi-blind deconvolution(HMSBD)method,are employed to deconvolute the white light-emitting diode(LED)spectra with two different color temperatures,respectively.The correction errors,root mean square errors,noise suppression ability,and the computation speed of above methods are compared.The experimental results prove the superiority of the proposed algorithm. | Chan HUANG Feinan CHEN Yuyang CHANG Lin HAN Shuang Li Jin HONG | 2020 | Photonic Sensors2020,10,3: | 2 |
| 20 | A novel isoform of ATOH8 promotes the metastasis of breast cancer by regulating RhoC显示文摘Metastases are the main cause of cancer-related mortality in breast cancer.Although significant progress has been made in the field of tumor metastasis,the exact molecular mechanisms involved in tumor metastasis are still unclear.Here,we report that ATOH8-V1,a novel isoform of ATOH8,is highly expressed in breast cancer and is a negative prognostic indicator of survival for patients.Forced expression of ATOH8-V1 dramatically enhances,while silencing of ATOH8-V1 decreases the metastasis of breast cancer cell lines.Moreover,ATOH8-V1 directly binds to the RhoC promoter and stimulates the expression of RhoC,which in turn enhances the metastasis of breast cancer.Altogether,our data demonstrate that ATOH8-V1 is a novel pro-metastatic factor that enhances cancer metastasis,suggesting that AT0H8-V1 is a potential therapeutic target for treatment of metastatic cancers. | Mengyao Xu Shan Huang Xiaoli Dong Yanan Chen Miao Li Wen Shi Guanwen Wang Chongbiao Huang Qiong Wang Yanhua Liu Peiqing Sun Shuang Yang Rong Xiang Antao Chang | 2021 | Journal of Molecular Cell Biology2021,13,1: | 2 |
