| 1 | Relationship between plasma D(-)-lactate and intestinal damage after severe injuries in rats显示文摘AIM To explore the kinetic changes in plasma D (-)lactate and lipopolysaccharide ( LPS ) levels, and investigate whether D (-)-lactate could be used as a marker of intestinal injury in rats following gut ischemia/reperfusion, burn, and acute necrotizing pancreatitis (ANP).METHODS Three models were developed in rats:gut ischemia/reperfusion obtained by one hour of superior severe burn injury created by 30% of total body surface induced by continuous inverse infusion of sodium taurocholate and trypsin into main pancreatic duct.Plasma levels of D( - )-lactate in systemic circulation and LPS in portal circulation were measured by enzymaticspectrophotometric method and limulus amebocyte lysate (LAL) test kit, respectively. Tissue samples of intestine were taken for histological analysis.RESULTS One hour gut ischemia followed by reperfusion injuries resulted in a significant elevation in plasma D( - )lactate and LPS levels, and there was a significant correlation between the plasma D( - )-lactate and LPS (r =0.719, P<0.05). The plasma concentrations of D(-)lactate and LPS increased significantly at 6 h postburn,and there was also a remarkable correlation between them (r = 0.877, P < 0.01). D ( - )-lactate and LPS levels elevated significantly at 2 h after ANP, with a similar significant correlation between the two levels (r-0.798,P < 0.01 ). The desquamation of intestine villi and infiltration of inflammatory cells in the lamina propria were observed in all groups.CONCLUSION The changes of plasma D( - )-lactate levels in systemic blood paralleled with LPS levels in the portal vein blood. The measurement of plasma D (-)-lactate level may be a useful marker to assess the intestinal injury and to monitor an increase of intestinal permeability and endotoxemia following severe injuries in early stage. | Xiao-Qing Sun Xiao-Bing Fu Rong-Zhan Yi Lü Qun Deng Xiao-Guo Jian Zhi-Yong Sheng Bum Institute, 304~(th)Hospital,Beijing 100037,China Department of General Surgery,Chinese PLA 304 Hospital,Beijing 100037,China | 2001 | World Journal of Gastroenterology2001,7,4: | 56 |
| 2 | Injectable hydrogels for cartilage and bone tissue engineering显示文摘Tissue engineering has become a promising strategy for repairing damaged cartilage and bone tissue. Among the scaffolds for tissue-engineering applications, injectable hydrogels have demonstrated great potential for use as three-dimensional cell culture scaffolds in cartilage and bone tissue engineering, owing to their high water content, similarity to the natural extracellular matrix(ECM), porous framework for cell transplantation and proliferation, minimal invasive properties, and ability to match irregular defects. In this review, we describe the selection of appropriate biomaterials and fabrication methods to prepare novel injectable hydrogels for cartilage and bone tissue engineering. In addition, the biology of cartilage and the bony ECM is also summarized. Finally, future perspectives for injectable hydrogels in cartilage and bone tissue engineering are discussed. | Mei Liu Xin Zeng Chao Ma Huan Yi Zeeshan Ali Xianbo Mou Song Li Yan Deng Nongyue He | 2017 | Bone Research2017,5,2: | 54 |
| 3 | Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children. | Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao | 2020 | World Journal of Pediatrics2020,16,3: | 56 |
| 4 | Effects of citrus tree-shape and spraying height of small unmanned aerial vehicle on droplet distribution显示文摘In order to explore the droplet penetration of spraying with unmanned aerial vehicle(UAV)on citrus trees with different shapes,the tests were carried out at different working heights.The material was five years old Cocktail grapefruit(Citrus paradisi cv.Cocktail)grafted on Trafoliata(Poncirus trifoliata L.Raf.)and the type of UAV sprayer used was the 3W-LWS-Q60S.A solution of 300 times Ponceau 2R diluents liquid instead of pesticide was used for citrus fields spraying and the droplets were collected by paper cards.Droplets deposition parameters were extracted and analyzed using digital image processing after scanning the cards.The results showed that:1)For the trees with round head shape canopy,the droplet depositions of the upper,middle and lower layers had a significant difference at 0.05 level.The droplet deposition had the best effect when the working height was 1.0 m,where the average droplet deposition densities were 39.97 droplets/cm2 and the average droplet size was 0.30 mm,but the droplet coverage(3.19%)was lower than that at the working height of 1.5 m(4.27%).2)Under three different working heights of UAV,the tree with open center shape can obtain higher droplet deposition density at all three layers than that with the round head shape canopy.It was especially prominent when the working height was 1.0 m,as the middle layer increased by 49.92%.However,the higher range of droplet deposition density meant larger fluctuation and dispersion.3)The open center shape canopy and the 1.0 m working height obviously improved the droplet coverage rate and droplet density in the citrus plant.For these parameters of open center shape citrus tree,there was no obvious difference in the front and rear direction,but in the left and middle part of the tree crown,the difference reached a 0.05 significant level.Considering droplet deposition characteristics and the spray uniformity,the UAV performed better when working on open center shape plants at a 1.0 m working height. | Zhang Pan Deng Lie Lyu Qiang He Shaolan Yi Shilai Liu Yande Yu Yongxu Pan Haiyang | 2016 | International Journal of Agricultural and Biological Engineering2016,9,4: | 37 |
| 5 | Analysis of factors associated with disease outcomes in hospitalized patients with 2019 novel coronavirus disease显示文摘Background Since early December 2019,the 2019 novel coronavirus disease(COVID-19)has caused pneumonia epidemic in Wuhan,Hubei province of China.This study aimed to investigate the factors affecting the progression of pneumonia in COVID-19 patients.Associated results will be used to evaluate the prognosis and to find the optimal treatment regimens for COVID-19 pneumonia.Methods Patients tested positive for the COVID-19 based on nucleic acid detection were included in this study.Patients were admitted to 3 tertiary hospitals in Wuhan between December 30,2019,and January 15,2020.Individual data,laboratory indices,imaging characteristics,and clinical data were collected,and statistical analysis was performed.Based on clinical typing results,the patients were divided into a progression group or an improvement/stabilization group.Continuous variables were analyzed using independent samples t-test or Mann-Whitney U test.Categorical variables were analyzed using Chi-squared test or Fisher’s exact test.Logistic regression analysis was performed to explore the risk factors for disease progression.Results Seventy-eight patients with COVID-19-induced pneumonia met the inclusion criteria and were included in this study.Efficacy evaluation at 2 weeks after hospitalization indicated that 11 patients(14.1%)had deteriorated,and 67 patients(85.9%)had improved/stabilized.The patients in the progression group were significantly older than those in the disease improvement/stabilization group(66[51,70]vs.37[32,41]years,U=4.932,P=0.001).The progression group had a significantly higher proportion of patients with a history of smoking than the improvement/stabilization group(27.3%vs.3.0%,χ^2=9.291,P=0.018).For all the 78 patients,fever was the most common initial symptom,and the maximum body temperature at admission was significantly higher in the progression group than in the improvement/stabilization group(38.2[37.8,38.6]vs.37.5[37.0,38.4]°C,U=2.057,P=0.027).Moreover,the proportion of patients with respiratory failure(54.5%vs.20.9%,χ^2=5.611,P=0.028)and respiratory rate(34[18,48]vs.24[16,60]breaths/min,U=4.030,P=0.004)were significantly higher in the progression group than in the improvement/stabilization group.C-reactive protein was significantly elevated in the progression group compared to the improvement/stabilization group(38.9[14.3,64.8]vs.10.6[1.9,33.1]mg/L,U=1.315,P=0.024).Albumin was significantly lower in the progression group than in the improvement/stabilization group(36.62±6.60 vs.41.27±4.55 g/L,U=2.843,P=0.006).Patients in the progression group were more likely to receive high-level respiratory support than in the improvement/stabilization group(χ^2=16.01,P=0.001).Multivariate logistic analysis indicated that age(odds ratio[OR],8.546;95%confidence interval[CI]:1.628-44.864;P=0.011),history of smoking(OR,14.285;95%CI:1.577-25.000;P=0.018),maximum body temperature at admission(OR,8.999;95%CI:1.036-78.147,P=0.046),respiratory failure(OR,8.772,95%CI:1.942-40.000;P=0.016),albumin(OR,7.353,95%CI:1.098-50.000;P=0.003),and C-reactive protein(OR,10.530;95%CI:1.224-34.701,P=0.028)were risk factors for disease progression.Conclusions Several factors that led to the progression of COVID-19 pneumonia were identified,including age,history of smoking,maximum body temperature at admission,respiratory failure,albumin,and C-reactive protein.These results can be used to further enhance the ability of management of COVID-19 pneumonia. | Wei Liu Zhao-Wu Tao Lei Wang Ming-Li Yuan Kui Liu Ling Zhou Shuang Wei Yan Deng Jing Liu Hui-Guo Liu Ming Yang Yi Hu | 2020 | Chinese Medical Journal2020,,9: | 31 |
| 6 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021,41,11: | 29 |
| 7 | Microstructure and Abrasive Wear Behavior of Medium Carbon Low Alloy Martensitic Abrasion Resistant Steel显示文摘The effect of processing parameters such as hot rolling and heat treatment on microstructure and mechanical properties was investigated for a new 0.27mass% C and Ni,Mo-free low alloy martensitic abrasion resistant steel.The three-body impact abrasive wear behavior was also analyzed.The results showed that two-step controlled rolling besides quenching at 880℃and tempering at 170℃could result in optimal mechanical property:the Brinell hardness,tensile strength,elongation and-40 ℃impact toughness were 531,1 530 MPa,11.8% and 58J,respectively.The microstructure was of fine lath martensite with little retained austenite.Three-body impact abrasive wear results showed that wear mechanism was mainly of plastic deformation fatigue when the impact energy was 2J, and the relative wear resistance was 1.04times higher than that of the same grade compared steel under the same working condition.The optimal hardness and toughness match was the main reason of higher wear resistance. | Xiang-tao DENG Zhao-dong WANG Yi HAN Hui ZHAO Guo-dong WANG | 2014 | Journal of Iron and Steel Research(International)2014,21,1: | 25 |
| 8 | Effects of dietary yeast β-glucan on nutrient digestibility and serum profiles in pre-ruminant Holstein calves显示文摘This study aimed to investigate the effects of dietary supplementation of yeast β-glucan on the nutrient digestibility and serum profiles in pre-ruminant Holstein calves. Forty-two neonatal Holstein calves((39.6±4.2) kg) were randomly allotted to six groups, and each was offered one of the following diets: a basal diet(control) or the basal diet supplemented with 25, 50, 75, 100 or 200 mg of yeast β-glucan kg–1 feed(dry matter basis). The basal diet consisted of a milk replacer and a starter feed. The trial lasted for 56 d. Two digestibility trials were conducted from d 14 to 20 and from d 42 to 48. Blood samples were collected on d 0, 14, 28 and 42 for serum profile analyses. On d 56, three calves from each group were slaughtered, and intestinal samples were collected to assess the villous height, crypt depth and mucosal thickness. Although feed intake was not affected by dietary treatment(P>0.05), the average daily gain(ADG) and gain-to-feed ratios were higher(P<0.05) for the calves fed 75 mg of yeast β-glucan kg–1 feed than those in the other groups. The supplementation of yeast β-glucan at 75 mg kg–1 feed increased the apparent digestibility of dry matter(DM), crude protein(CP), ether extract(EE), and phosphorus(P)(P<0.05) and the ratio of intestinal villous height to crypt depth(V/C)(P<0.05) when compared with the control group. No effects of yeast β-glucan on the serum concentrations of total protein(TP), albumin(ALB), serum urea nitrogen(SUN) and glucose(GLU) were observed(P>0.05). Compared with the control group, supplementation of yeast β-glucan decreased(P<0.05) the serum concentrations of triglycerides(TG) and total cholesterol(TC). The serum concentration of immunoglobulin G(Ig G) and immunoglobulin M(Ig M) increased quadratically(P<0.05), whereas the serum concentration of immunoglobulin A(Ig A) was unaffected by dietary treatments(P>0.05). The supplementation of yeast β-glucan stimulated the enzymatic activity of alkaline phosphatase(ALP)(P<0.05) compared with the control group. The lysozyme(LYZ) concentration increased quadratically(P<0.05) with increasing yeast β-glucan levels. The results suggested that dietary supplementation of yeast β-glucan at 75 mg kg–1 feed improved nutrient digestibility, enhanced immunity by increasing the immunoglobulin concentration and stimulating ALP, and exerted no adverse effects on metabolism in pre-ruminant calves. | MA Tao TU Yan ZHANG Nai-feng GUO Jiang-peng DENG Kai-dong ZHOU Yi YUN Qiang DIAO Qi-yu | 2015 | Journal of Integrative Agriculture2015,14,4: | 23 |
| 9 | Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI. | Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN | 2019 | Journal of Geriatric Cardiology2019,16,6: | 22 |
| 10 | Spatial variability of soil total nitrogen,phosphorus and potassium in Renshou County of Sichuan Basin,China显示文摘Understanding soil nutrient distributions and the factors affecting them are crucial for fertilizer management and environmental protection in vulnerable ecological regions.Based on 555 soil samples collected in 2012 in Renshou County,located in the purple soil hilly area of Sichuan Basin,China,the spatial variability of soil total nitrogen(TN),total phosphorus(TP)and total potassium(TK)was studied with geostatistical analysis and the relative roles of the affecting factors were quantified using regression analysis.The means of TN,TP and TK contents were 1.12,0.82 and 9.64 g kg^(–1),respectively.The coefficients of variation ranged from 30.56 to 38.75%and the nugget/sill ratios ranged from 0.45 to 0.61,indicating that the three soil nutrients had moderate variability and spatial dependence.Two distribution patterns were observed.TP and TK were associated with patterns of obvious spatial distribution trends while the spatial distribution of TN was characterized by higher variability.Soil group,land use type and topographic factors explained 26.5,35.6 and 8.4%of TN variability,respectively,with land use being the dominant factor.Parent material,soil group,land use type and topographic factors explained 17.5,10.7,12.0 and 5.0%of TP variability,respectively,and both parent material and land use type played important roles.Only parent material and soil type contributed to TK variability and could explain 25.1 and 13.7%of TK variability,respectively.More attention should focus on adopting reasonable land use types for the purposes of fertilizer management and consider the different roles of the affecting factors at the landscape scale in this purple soil hilly area. | GAO Xue-song XIAO Yi DENG Liang-ji LI Qi-quan WANG Chang-quan LI Bing DENG Ou-ping ZENG Min | 2019 | Journal of Integrative Agriculture2019,18,2: | 19 |
| 11 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016,1,1: | 19 |

| 13 | STAT-3 correlates with lymph node metastasis and cell survival in gastric cancer显示文摘AIM:To investigate the correlation between gastric cancer growth and signal transducer and activator of transcription-3(STAT3) expression.METHODS:We assessed the expressions of STAT3,phosphor-STAT3(pSTAT3),suppressor of cytokine signaling-1(SOCS-1),survivin and Bcl-2 in gastric cancer patients after gastrectomy by immunohistochemical method.In addition,in situ hybridization was used to further demonstrate the mRNA expression of STAT3 in gastric cancer.RESULTS:With the univariate analysis,expressions of STAT3,pSTAT3,SOCS-1,survivin and Bcl-2,the size of primary tumor and the lymph node metastasis were found to be associated with the overall survival(OS) of gastric cancer patients.However,only pSTAT3 expression and the lymph node metastasis were identified as the independent factors of OS of gastric cancer with multivariate analysis.STAT3 expression was correlated with the lymph node metastasis.There were positive correlations between expressions of STAT3,survivin,Bcl-2 and pSTAT3 in gastric cancer,whereas there was negative correlation between STAT3 expression and SOCS-1 expression in gastric cancer.CONCLUSION:STAT3 can transform into pSTAT3 to promote the survival and inhibit the apoptosis of gastric cancer cells.SOCS-1 might be the valid molecular antagonist to inhibit the STAT3 expression in gastric cancer. | Jing-Yu Deng Xiang-Yu Liu Han Liang Dan Sun Yi Pan | 2010 | World Journal of Gastroenterology2010,16,42: | 16 |
| 14 | Oroxindin inhibits macrophage NLRP3 inflammasome activation in DSS-induced ulcerative colitis in mice via suppressing TXNIP-dependent NF-κB pathway显示文摘Oroxindin is a flavonoid isolated from the traditional Chinese medicine Huang-Qin,which has shown various pharmacological activities including anti-inflammatory,antitumor,antioxidant,etc.Thus far,the effect of oroxindin on colonic inflammation and the underlying mechanism remain unknown.In this study,we investigated the tissue distribution of oroxindin and its therapeutic effects on ulcerative colitis(UC)as well as the underlying mechanisms.UC model was established in mice by administrating dextran sulfate sodium(DSS)in drinking water for 7 d.We first showed that oroxindin was largely absorbed by the colon as an active ingredient after normal mice received Huang-Qin-Tang,a traditional Chinese medicine decoction.UC mice were then treated with oroxindin(12.5,25,50 mg-kg^-1·d^-1,i.g.)for 10 d.We found that oroxindin treatment greatly suppressed massive macrophages infiltration and attenuated pathological changes in colonic tissue.Furthermore,oroxindin treatment significantly inhibited the generation of IL-13 and IL-18 in the colon via inhibiting the nucleotide-binding oligomerization domain-like receptor 3(NLRP3)inflammasome formation and activation.In cultured macrophages,LPS induced NLRp3 inflammasome formation and caspase-1 activation,which were suppressed by oroxindin(12.5-50μM).In LPS-treated macrophages,oroxindin dose-dependently restored the expression of TXNIP protein,leading to suppressing TXNIP-dependent NF-κB activation.In conclusion,these results demonstrate that oroxindin could be absorbed by the colon and attenuate inflammatory responses via inhibiting NLRP3 inflammasome formation and activation,which is related to the inhibitory effect on TXNIP-dependent NF-κB-signaling pathway.Hence,oroxindin has the potential of becoming an effective drug for treating UC. | Qi Liu Rui Zuo Kai Wang Fei-fei Nong Ya-jun Fu Shao-wei Huang Zeng-feng Pan Yi Zhang Xia Luo Xiang-liang Deng Xiao-xue Zhang Lian Zhou Yang Chen | 2020 | Acta Pharmacologica Sinica2020,41,6: | 15 |
| 15 | Bone marrow mesenchymal stem cell transplantation for treatment of spinal cord injury An in vivo magnetic resonance imaging tracking study显示文摘Non-invasive tracing in vivo can be used to observe the migration and distribution of grafted stem cells,and can provide experimental evidence for treatment.This study utilized adenovirus-carrying enhanced green fluorescent protein(AD5/F35-eGFP) and superparamagnetic iron oxide(SPIO)-labeled bone marrow mesenchymal stem cells(BMSCs).BMSCs,double-labeled by AD5/F35-eGFP and SPIO,were transplanted into rats with spinal cord injury via the subarachnoid space.MRI tracing results demonstrated that BMSCs migrated to the injured spinal cord over time(T2 hypointensity signals).This result was verified by immunofluorescence.These results indicate that MRI can be utilized to trace in vivo the SPIO-labeled BMSCs after grafting. | Yu Liu Boai Zhang Yi Song Yubin Deng Yanjie Jia Qiyong Gong | 2011 | Neural Regeneration Research2011,6,13: | 14 |

The primary endpoints were overall survival and progression-free survival, and the secondary endpoints were toxicity and the treatment failure pattern.RESULTS A total of 76 patients were enrolled in this study, of whom 63.2% finished the whole regimen. The 5-year survival rates for the per-protocol population and intent-to-treat population were 25.4% and 26.4%, respectively, and the median survival rates were 23.7 mo and 28.5 mo, respectively. Grade 3 or 4 late toxicity was observed in only one patient(heart failure). In log-rank analysis, the pretreatment stage(stage Ⅱ + Ⅲ: 36.1 mo vs stage Ⅳ: 14.9 mo) and the completed cycle(1-3 cycles: 16.1 mo vs 4 cycles: 35.5 mo) were significant prognostic factors(P = 0.037 < 0.05 and P = 0.013 < 0.05).CONCLUSION Radiotherapy combined with chemotherapy consisting of PTX and DDP is a safe and effective definitive treatment for loco-regionally advanced esophageal squamous cancer. | Han-Ting Zhu Da-Shan Ai Hua-Rong Tang Harun Badakhshi Jian-Hong Fan Jia-Ying Deng Jun-Hua Zhang Yun Chen Zhen Zhang Yi Xia Xiao-Mao Guo Guo-Liang Jiang Kuai-Le Zhao | 2017 | World Journal of Gastroenterology2017,23,3: | 14 |
| 18 | The Genesis Mechanism of the Mantle Fluid Action and Evolution in the Ore-Forming Process: A Case Study of the Laowangzhai Gold Deposit in Yunnan, China显示文摘Based on petrological studies of the wall rocks, mineralizing rocks, ores and veins from the Laowangzhai gold deposit, it is discovered that along with the development of silication, carbonation and sulfidation, a kind of black opaque ultra-microlite material runs through the spaces between grains, fissures and cleavages. Under observations of the electron microprobe, scanning electronic microscopy and energy spectrum, this kind of ultra-microlite material is confirmed to consist of ultra microcrystalline quartz, silicate, sulfides and carbonates, as well as rutile, scheelite and specularite (magnetite), showing characters of liquation by the analyses of SEM and energy spectrum. The coexistence of immiscibility and precipitating co-crystallization strongly suggests that the mineralizing fluid changed from the melt to the hydrothermal fluid. Combined with the element geochemical researches, it is realized that the ultra-microlite aggregate is the direct relics of the mantle fluid behaving like a melt and supercritical fluid, which goes along with the mantle-derived magma and will escape from the magma body at a proper time. During the alteration process, the nature of the mantle fluid changed and it is mixed with the crustal fluid, which are favorable for mineralization in the Loawangzhai gold deposit. | LIU Xianfan LI Chunhui LU Qiuxia DENG Biping SONG Xiangfeng ZHAO Fufeng CHU Yating XIAO Jixiong YI Liwen HUANG Yupeng | 2012 | Acta Geologica Sinica(English Edition)2012,86,3: | 13 |
| 19 | An advanced carbon dioxide retrieval algorithm for satellite measurements and its application to GOSAT observations显示文摘An advanced carbon dioxide retrieval algorithm for satellite observations has been developed at the Institute of Atmospheric Physics, Chinese Academy of Sciences. The algorithm is tested using Greenhouse gases Observing SATellite(GOSAT) L1 B data and validated using the Total Column Carbon Observing Network(TCCON) measurements. The retrieved XCO2 agrees well with TCCON measurements in a low bias of 0.15 ppmv and RMSE of 1.48 ppmv, and captured the seasonal variation and increasing of XCO2 in Northern and Southern Hemisphere, respectively, as other measurements. | Dongxu Yang Yi Liu Zhaonan Cai Jianbo Deng Jing Wang Xi Chen | 2015 | Science Bulletin2015,60,23: | 12 |
| 20 | Astronomical tuning and magnetostratigraphy of Neogene biogenic reefs in Xisha Islands, South China Sea显示文摘Biogenic reefs are one of two major depositional types in the South China Sea, and are constructed by coral, algae and bryozoa. The West Pacific is a major area of biogenic reef development and plays a critical role in the global carbon cycle. However, the lack of geochronological studies in previous works inhibits our understanding of their contributions. Herein, we conduct a cyclostratigraphic and magnetostratigraphic study on Neogene biogenic reefs using the XK–1 core that was drilled at the Shidao Island,Xisha(Paracel) Islands. The main findings of this study are:(1) the establishment of reliable magentostratigraphy for Ledong, Huangliu, Meishan and Sanya Formations;(2) the magnetic susceptibility variation can be inferred as growth index and tuned to the 405–ka long eccentricity cycle;(3) the astronomical geochronology suggests that the bottom ages for Ledong, Yinggehai, Huangliu, Meishan,and Sanya Formations are 2.2 Ma, 5.7 Ma, 10.4 Ma, 16.6 Ma, and 24.3 Ma, respectively; and (4) Earth's eccentricity and obliquity played predominant roles in biogenic reef establishment on orbital to tectonic timescales. Thus, the reported geochronology offers an opportunity to test the contributions of various factors and hypothesize their roles in the global carbon cycle in future. | Liang Yi Zhimin Jian Xinyu Liu Youhua Zhu Daojun Zhang Zhenfeng Wang Chenglong Deng | 2018 | Science Bulletin2018,63,9: | 12 |
