2Secukinumab demonstrates high efficacy and a favorable safety profile over 52 weeks in Chinese patients with moderate to severe plaque psoriasis显示文摘Background:Psoriasis is a chronic inflammatory skin disease,affecting about 0.6%of the Chinese population.Many patients are not well controlled by conventional treatments,thus there is need for new treatment regimens.In this study,we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.Methods:This study was a 52-week,multicentre,randomized,double-blind,placebo-controlled,parallel-group,Phase 3 trial.A sub-population of study participants(≥18 years)of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab,or placebo.The co-primary endpoints were psoriasis area severity index(PASI)75 and Investigator’s Global Assessment(IGA)0/1 at Week 12.Results:A total of 441 Chinese patients were enrolled in this study.Co-primary outcomes were achieved;300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75(97.7%and 87.2%vs.3.7%,respectively;P<0.001),and IGA 0/1(82.3%and 69.7%vs.2.7%;P<0.001)at Week 12.Treatment efficacy was maintained until Week 52.There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period.Conclusion:Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.Lin Cai Jian-Zhong Zhang Xu Yao Jun Gu Quan-Zhong Liu Min Zheng Shi-Fa Zhang Jin-Hua Xu Cheng-Xin Li Hao Cheng Qing Guo Wei-Li Pan Shen-Qiu Li Ruo-Yu Li Zai-Pei Guo Zhi-Qi Song Shan-Shan Li Xiu-Qin Dong Linda Wang Rong Fu Pascaline Regnault Pascal Charef Ratal Mazur Manmath Patekar 2020Chinese Medical Journal2020,,22:21
3BMAL1 knockout macaque monkeys display reduced sleep and psychiatric disorders显示文摘Circadian disruption is a risk factor for metabolic, psychiatric and age-related disorders, and non-human primate models could help to develop therapeutic treatments. Here, we report the generation of BMAL1 knockout cynomolgus monkeys for circadian-related disorders by CRISPR/Cas9 editing of monkey embryos. These monkeys showed higher nocturnal locomotion and reduced sleep, which was further exacerbated by a constant light regimen. Physiological circadian disruption was reflected by the markedly dampened and arrhythmic blood hormonal levels. Furthermore, BMAL1-deficient monkeys exhibited anxiety and depression, consistent with their stably elevated blood cortisol, and defective sensory processing in auditory oddball tests found in schizophrenia patients. Ablation of BMAL1 up-regulated transcriptional programs toward inflammatory and stress responses, with transcription networks associated with human sleep deprivation, major depressive disorders, and aging. Thus, BMAL1 knockout monkeys are potentially useful for studying the physiological consequences of circadian disturbance, and for developing therapies for circadian and psychiatric disorders.Peiyuan Qiu Jian Jiang Zhen Liu Yijun Cai Tao Huang Yan Wang Qiming Liu Yanhong Nie Fang Liu Jiumu Cheng Qing Li Yun-Chi Tang Mu-ming Poo Qiang Sun Hung-Chun Chang 2019National Science Review2019,6,1:21

7Relationship of Inflammation and Endothelial Dysfunction with Risks to Cardiovascular Disease among People in Inner Mongolia of China显示文摘Objective To explore the relationship of inflammation and endothelial dysfunction with risks to cardiovascular disease(CVD).Methods Blood pressure,body weight,body height,waist circumference and lifestyle risk factors were measured and studied among 2589 participants in Inner Mongolia of China,and biomarkers of inflammation and endothelial dysfunction including high-sensitivity C-reactive protein(hsCRP),soluble inter-cellular adhesion molecule-1(sICAM-1),soluble E-selectin(sE-selectin),and angiotensin II were investigated.Results Subjects with metabolic risk factors for CVD had higher levels of hsCRP,sE-selectin and sICAM-1 than those without such risk factors(all P<0.05).Levels of all biomarkers positively and significantly increased with aggregation of the metabolic risk factors among the subjects(all P for trend<0.001).Data from the multivariate analysis showed that participants with high levels of hsCRP [odds ratio(OR): 1.96,95% confidence interval(CI): 1.52-2.53],sE-selectin(OR: 1.35,95% CI: 1.05-1.72),and angiotensin II(OR: 1.81,95% CI: 1.40-2.33) were more likely to develop hypertension; participants with high levels of hsCRP(OR: 2.33,95% CI: 1.85-2.94),sE-selectin(OR: 1.24,95% CI: 1.00-1.54),and sICAM-1(OR: 1.70,95% CI: 1.30-2.22) were more likely to develop dyslipidemia,and those with high levels of hsCRP(OR: 2.95,95% CI: 2.27-3.83) and sICAM-1(OR: 2.80,95% CI: 2.06-3.80) were more likely to develop hyperglycemia.Conclusion Biomarkers of inflammation and endothelial dysfunction were separately associated with relevant metabolic risk factors for CVD.And appropriate measures should be taken to control inflammation and improve endothelial function among individuals with different metabolic risk factors for CVD.PENG Hao HAN Shu Hai LIU Hai Ying Vasisht CHANDNI CAI Xiao Qing ZHANG Yong Hong 2013Biomedical and Environmental Sciences2013,26,10:15
8Bacterial infection triggers and complicates acute-on-chronic liver failure in patients with hepatitis B virus-decompensated cirrhosis: A retrospective cohort study显示文摘BACKGROUND Reports on bacterial infection(BI)in decompensated cirrhosis(DC)is mainly from alcoholic cirrhosis.The role of BI as a trigger or complication of acute-onchronic liver failure(ACLF)in patients with hepatitis B virus decompensated cirrhosis(HBV-DC)remains to be investigated.AIM To investigate the impact of BI on the outcomes of the patients with HBV-DC admitted into the hospital with or without ACLF.METHODS This retrospective study included patients with HBV-DC admitted to two tertiary centers in China.In-hospital overall survival,90-d transplant-free survival,5-year post-discharge survival,and cumulative incidence of ACLF were evaluated.Risk factors for death were analyzed considering liver transplantation as a competing event.RESULTS A total of 1281 hospitalized HBV-DC patients were included;284 had ACLF at admission.The overall prevalence of BI was 28.1%.The patients with BI had a significantly lower in-hospital survival and transplant-free 90-d survival than those without,in both the patients admitted with and without ACLF.The presence of BI significantly increased the risk of developing ACLF[subdistribution hazard ratio(sHR)=2.52,95%CI:1.75-3.61,P<0.001]in the patients without ACLF.In the patients discharged alive,those who had an episode of BI had a significantly lower 5-year transplant-free survival.BI was an independent risk factor for death in the patients admitted without ACLF(sHR=3.28,95%CI:1.93-5.57),while in ACLF admissions,the presence of pneumonia,but not other type of BI,independently increased the risk of death(sHR=1.87,95%CI:1.24-2.82).CONCLUSION BI triggers ACLF in patients with HBV-DC and significantly impairs short-term survival.HBV-DC patients should be monitored carefully for the development of BI,especially pneumonia,to avoid an adverse outcome.Zhu-Jun Cao Yu-Han Liu Chuan-Wu Zhu Shan Yin Wei-Jing Wang Wei-Liang Tang Gang-De Zhao Yu-Min Xu Lu Chen Tian-Hui Zhou Ming-Hao Cai Hui Wang Wei Cai Shi-San Bao Hai Li Qing Xie 2020World Journal of Gastroenterology2020,26,6:15
9The prognostic and therapeutic implications of circulating tumor cell phenotype detection based on epithelial-mesenchymal transition markers in the first-line chemotherapy of HER2-negative metastatic breast cancer显示文摘Background:Epithelial-mesenchymal transition(EMT)is implicated in the metastatic process and presents a chal-lenge to epithelial cell adhesion molecule-based detection of circulating tumor cells(CTCs),which have been demon-strated to be a prognostic indicator in metastatic breast cancer.Although evidence has indicated that heterogeneity of CTCs based on EMT markers is associated with disease progression,no standard recommendations have been established for clinical practice.This study aimed to evaluate the prognostic significance of dynamic CTC detection based on EMT for metastatic breast cancer patients.Methods:We enrolled 108 human epidermal growth factor receptor 2-negative metastatic breast cancer patients from the prospective phase III CAMELLIA study and applied the CanPatrol CTC enrichment technique to identify CTC phenotypes(including epithelial CTCs,biphenotypic epithelial/mesenchymal CTCs,and mesenchymal CTCs)in peripheral blood samples.Receiver operating characteristic curve analyses of total CTC count and the proportion of mesenchymal CTCs for predicting the 1-year progression-free survival(PFS)rate were conducted to determine the optimal cut-off values,and Kaplan-Meier analysis and Cox proportional hazards regression analysis were performed to investigate the prognostic value of the cut-off values of both total CTC count and the proportion of mesenchymal CTCs in combination.Results:For predicting the 1-year PFS rate,the optimal cut-off value of total CTC count was 9.5(Area under the curve[AUC]=0.538,95%confidence interval[CI]=0.418-0.657),and that of the proportion of mesenchymal CTCs was 10.7%(AUC=0.581,95%CI=0.463-0.699).We used the two cut-off values in combination to forecast PFS in which the total CTC count was equaled to or exceeded 10/5 mL with the proportion of mesenchymal CTCs surpassed 10.7%.Patients who met the combined criteria had significantly shorter median PFS than did those who did not meet the criteria(6.2 vs.9.9 months,P=0.010).A nomogram was constructed based on the criteria and significant clinicopatho-logical characteristics with a C-index of 0.613(P=0.010).Conclusions: The criteria, which combine the total CTC count and the proportion of mesenchymal CTCs, may be used to monitor therapeutic resistance and predict prognosis in patients with metastatic breast cancer.Xiuwen Guan Fei Ma Chunxiao Li Shiyang Wu Shangying Hu Jiefen Huang Xiaoying Sun Jiayu Wang Yang Luo Ruigang Cai Ying Fan Qiao Li Shanshan Chen Pin Zhang Qing Li Binghe Xu 2019Cancer Communications2019,39,1:15
10Overexpression of potato miR482e enhanced plant sensitivity to Verticillium dahliae infection显示文摘Verticillium wilt of potato is caused by the fungus pathogen Verticillium dahliae. Present s RNA sequencing data revealed that miR482 was in response to V. dahliae infection but the function in potato is elusive. Here, we characterized potato miR482 family and its putative role resistance to Verticillium wilt. Members of the potato mi R482 superfamily are variable in sequence, but all variants target a class of disease-resistance proteins with nucleotide binding site(NBS)and leucine-rich repeat(LRR) motifs. When potato plantlets were infected with V. dahliae, the expression level of miR482e was downregulated, and that of several NBS-LRR targets of miR482e were upregulated. Transgenic potato plantlets overexpressing miR482e showed hypersensitivity to V. dahliae infection. Using s RNA and degradome datasets, we validated that miR482e targets m RNAs of NBS-LRR disease-resistance proteins and triggers the production of trans-acting(ta)si RNAs, most of which target m RNAs of defense-related proteins. Thus, the hypersensitivity of transgenic potato could be explained by enhanced miR482e and miR482e-derived tasi RNA-mediated silencing on NBS-LRR-disease-resistance proteins. It is speculated that a miR482-mediated silencing cascade mechanism is involved in regulating potato resistance against V. dahliae infection and could be a counter defense action of plant in response to pathogen infection.Liu Yang Xiaoying Mu Chao Liu Jinghui Cai Ke Shi Wenjiao Zhu Qing Yang 2015Journal of Integrative Plant Biology2015,57,12:14
11Echinacoside Protects Against MPP+-Induced Neuronal Apoptosis via ROS/ATF3/CHOP Pathway Regulation显示文摘Echinacoside(ECH) is protective in a mouse model of Parkinson's disease(PD) induced by 1-methyl-4-phenylpyridinium ion(MPP^+). To investigate the mechanisms involved, SH-SY5Y neuroblastoma cells were treated with MPP^+or a combination of MPP^+and ECH,and the expression of ATF3(activating transcription factor3), CHOP(C/EBP-homologous protein), SCNA(synuclein alpha), and GDNF(glial cell line-derived neurotrophic factor) was assessed. The results showed that ECH significantly improved cell survival by inhibiting the generation of MPP^+-induced reactive oxygen species(ROS). In addition, ECH suppressed the ROS and MPP^+-induced expression of apoptotic genes(ATF3, CHOP, and SCNA). ECH markedly decreased the MPP^+-induced caspase-3 activity in a dose-dependent manner. ATF3-knockdown also decreased the CHOP and cleaved caspase-3 levels and inhibited the apoptosis induced by MPP^+.Interestingly, ECH partially restored the GDNF expression that was down-regulated by MPP^+. ECH also improved dopaminergic neuron survival during MPP^+treatment and protected these neurons against the apoptosis induced by MPTP. Taken together, these data suggest that the ROS/ATF3/CHOP pathway plays a critical role in mechanisms by which ECH protects against MPP^+-induced apoptosis in PD.Qing Zhao Xiaoyan Yang Dingfang Cai Ling Ye Yuqing Hou Lijun Zhang Jiwei Cheng Yuan Shen Kaizhe Wang Yu Bai 2016Neuroscience Bulletin2016,32,4:14
12Orthogonal Test Design for Optimization of the Extraction of Flavonid from the Fructus Gardeniae显示文摘Objective It is imperative to provide some consistent experimental results for the extraction of flavonid from Fructus Gardeniae.Methods The key extraction parameters that influenced the yield of flavonid from Fructus Gardeniae were optimized by employing an orthogonal experiment [L9(3)4],including the ratio of buffer solution (Na2B4O7·10H2O) to raw material,concentration of Fructus Gardeniae in extracting solution,extraction time and pH of buffer solution.An UV/Vis detector was used to perform the qualitative and quantitative analyses of the extracted flavonid with the using of the standard sample.Results The maximum extraction yield of the crude extract was 5.0533 (mg/g) after 20 min when the mass ratio of Na2B4O7·10H2O to raw material was 0.4%,the concentration of Fructus Gardeniae in the extraction solution was 1/12 (g/mL),and pH of buffer solution was 4.5.The positive reactions to the Molish and HCl‐Mg tests suggested that the extracted compound was flavonoid,and FTIR measurements also identified the presence of flavonoid in the extracts.Conclusion This work is expected to provide a basis for further research,development,and utilization of Fructus gardenia in flavonid extraction.CAI Ding Jian SHU Qing XU Bao Quan PENG Li Mei HE Yan 2011Biomedical and Environmental Sciences2011,24,6:12

17The family Amanitaceae: molecular phylogeny, higher-rank taxonomy and the species in China显示文摘Mushrooms in the basidiomycete family Amanitaceae are very important both economically and ecologically.However,the delimitation of the family is still controversial,in part due to limited taxon sampling and in part because of insufficient gene fragment employed for molecular phylogenetic analyses.Furthermore,species diversity in the family is likely to have been largely underestimated,due to morphological similarity between taxa and phenotypic plasticity.In this study,we examined 1190 collections,including 1008 Chinese and 182 external ones,and performed the first comprehensive phylogenetic analyses of Amanitaceae using multi-locus sequence data.To test the monophyly of the Amanitaceae,a concatenated(nrLSU,rpb1,and rpb2)dataset of 200 taxa of the order Agaricales was analyzed.To infer the phylogeny of Amanitaceae,a concatenated nrLSU,tef1-a,rpb2 and b-tubulin dataset(3010 sequences from ca.890 samples with 2309 newly generated sequences)was used.In this dataset,252 sequences from the types of 77 species were provided.Our results indicate that Amanitaceae is a monophyletic group,and consists of five genera,namely Amanita,Catatrama,Limacella,Limacellopsis and Myxoderma.It is clear that Catatrama is closely related to Limacella,however,the phylogenetic relationships among these genera remain largely unresolved.Amanita contains 95%of the species in the family,and is here divided into three subgenera and eleven sections(subgen.Amanita,containing:sect.Amanita,sect.Amarrendiae,sect.Caesareae and sect.Vaginatae;subgen.Amanitina,containing:sect.Amidella,sect.Arenariae,sect.Phalloideae,sect.Roanokenses,sect.Strobiliformes and sect.Validae;and subgen.Lepidella,containing sect.Lepidella).Subgen.Lepidella occupies the basal position in the genus.One-hundred and sixty-two species of Amanitaceae known from China are treated in this study,including 50 novel species and 112 known taxa.Amanita gleocystidiosa,A.pyriformis,A.atrofusca,A.subjunquillea var.alba and A.areolata are treated as synonyms of A.sychnopyramis f.subannulata,A.orientigemmata,A.umbrinolutea,A.subjunquillea and A.zangii,respectively.26 extralimital taxa including a novel species,namelyCatatrama indica,were included in our study to allow us to make comparisons between these and the Chinese taxa.DNA sequence data for all the species of Amanitaceae in China and keys for identification of the species are provided.Yang-Yang Cui Qing Cai Li-Ping Tang Jian-Wei Liu Zhu L.Yang 2018Fungal Diversity2018,,4:10

19Experimental Study on Uniaxial and Multiaxial Strain CyclicCharacteristics and Ratcheting of 316L Stainless Steel显示文摘An experimental study was carried out on the strain cyclic characteristics and ratcheting of 316L stainless steel subjected to uniaxial and multiaxial cyclic loading. The strain cyclic characteristics were researched under the strain-controlled uniaxial tension-compression and multiaxial circular paths of loading. The ratcheting tests were conducted for the stress-controlled uniaxial tensioncompression and multiaxial circular, rhombic and linear paths of loading with different mean stresses, stress amplitudes and histories. The experiment results show that 316L stainless steel features the cyclic hardening, and its strain cyclic characteristics depend on the strain amplitude and its history apparently. The ratcheting of 316L stainless steel depends greatly on the values of mean stress, stress amplitude and their histories. In the meantime, the shape of load path and its history also apparently influence the ratcheting.GuoZheng KANG, Qing GAO, Lixun CAI, Xianjie YANG and Yafang SUN Department of Applied Mechanics and Engineering, Southwest Jiaotong University, Chengdu 610031, China 2001Journal of Materials Science & Technology2001,17,2:8
20Decreased Average Albumin-to-Globulin Ratio During Radiotherapy Worsens the Prognosis of Esophageal Squamous Cell Carcinoma:Implications for Nutritional Management显示文摘Objective Malnutrition and cachexia are common in esophageal squamous cell carcinoma(ESCC)patients undergoing radiotherapy.This study evaluated how malnutrition-and cachexia-related indicators,including the albumin-to-globulin ratio(AGR),and their changes during radiotherapy predict the treatment outcomes.Methods We reviewed a total of 172 ESCC patients receiving radiotherapy(as a primary cohort)and performed a Cox regression analysis on potential prognostic factors,including the AGR,as well as the TNM stage and concomitant chemotherapy.A subsequent receiver operating characteristics(ROC)curve and Kaplan Meier survival analysis was performed for ESCC patients stratified by the average AGR cut-off point.Results In addition to the well-documented factors(i.e.TNM stage and concomitant chemotherapy),the average AGR was a significant prognostic factor for ESCC patients receiving radiotherapy.By plotting the ROC curve of the average AGR with regard to the ESCC prognosis,we obtained cut-off points for the overall patients(cut-off point:1.5,AUC:0.636),for patients with stageⅡ/Ⅲdisease(cut-off point:1.5,AUC:0.611),and for patients with stageⅣdisease(cut-off point:1.84,AUC:0.900).The ESCC patients with higher average AGR had a significantly more favorable OS compared with those with a lower average AGR.Notably,ESCC patients who had an increasingΔAGR during radiotherapy had a considerably more favorable OS compared with those with a decreasingΔAGR.All of these findings were reproducible in the validation cohort.Conclusion A lower average AGR is indicative of a poorer prognosis for ESCC patients following radiotherapy.Improving the nutritional status and preventing or ameliorating cachexia might contribute to improving the prognosis of ESCC patients.Fen Cai Xiu Lian Zhang Xiao Ling Wu Ting Ting Zhuang Lei Huang Yi Fei Tu Yuan Yuan Lu Min Xia Jiang Qing Ying Zhang Yan Lin Chang Chun Ma 2021Journal of Nutritional Oncology2021,6,2:8
