| 2 | Ethyl pyruvate prevents inflammatory factors release and decreases intestinal permeability in rats with D-galactosamine-induced acute liver failure显示文摘BACKGROUND: The pathogenesis and progression of acute liver failure (ALF) are closely associated with intestinal endotoxemia because of the high permeability of the intestinal wall. Treatment with ethyl pyruvate (EP) has been shown to protect liver failure effectively. The current study aimed to explore the relationship between proinflammatory cytokines and intestinal permeability, and to investigate whether EP administration might prevent the release of multiple proinflammatory cytokines and decrease intestinal permeability and therefore, protect the liver from injury. METHODS: The ALF model was induced by D-galactosamine in rats. The rats were randomly divided into control (saline i.p.), model (D-galactosamine, 1.2 g/kg, i.p.), prevention [EP injection (40 mg/kg) 2 hours ahead of D-galactosamine] and treatment groups (EP injection 2 hours after D-galactosamine) Samples were obtained at 12 and 24 hours after ALF induction respectively. The histology of liver and intestinal tissue was accessed. Serum alanine aminotransferase, endotoxin, D(-) lactate, diamine oxidase (DAO), tumor necrosis factor-alpha (TNF-α), interferon-γ (IFN-γ) and high mobility group box-1 (HMGB1) were evaluated. The survival of rats was also recorded. RESULTS: The rats in model group showed severe damage to liver tissue and intestinal mucosa 12 and 24 hours after ALF induction. EP significantly improved liver or intestinal injury In addition, serum endotoxin, D(-)-lactate, DAO, TNF-α IFN-γ and HMGB1 levels were significantly increased in the model group compared with the control group. There was a positive correlation between intestinal permeability andproinflammatory cytokines. EP significantly reduced serum endotoxin, D(-)-lactate, DAO, TNF-α, IFN-γ and HMGB1 levels. The median survival time was significantly prolonged in both prevention and treatment groups (126 and 120 hours compared with 54 hours in the model group). CONCLUSIONS: EP has protective and therapeutic effects on intestinal mucosa. EP decreases intestinal permeability, and inhibits the release of multiple proinflammatory cytokines in rats with ALF. | Li-Kun Wang Lu-Wen Wang Xun Li Xiao-Qun Han Zuo-Jiong Gong | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,2: | 12 |
| 3 | Stromal cell derived factor-1 enhances bone marrow mononuclear cell migration in mice with acute liver failure显示文摘AIM:To evaluate the number of bone marrow mononuclear cells(BMMC) that are migrated to the liver following transplantation of murine BMMC into mice with acute liver injury.METHODS:BMMC were isolated from the bone marrow of mice in a lymphocyte separation medium and then labeled with PKH26.The labeled cells were subsequently infused into the caudal veins of BALB/c mice with hepatic injury induced by carbon tetrachloride and 2-acetylaminofluorene.Mice in experimental group were treated with stromal cell-derived factor-1(SDF-1) which was injected intraperitoneally after trans-plantation of BMMC.Mice in control group were injected intraperitoneally with 0.1 mL of saline(0.9% NaCl) after transplantation of BMMC.After 2 wk,migration of the cells in experimental group was studied by fluorescence microscopy.The expression of proliferating cell nuclear antigen and albumin was quantified with manual methods in both groups.The serum transaminase levels at different time points were compared between the two groups.RESULTS:The labeled 'cells' were found in the portalregion and central veins of hepatic lobules.The PKH26-labeled cells appeared at an average frequency of 108 ± 8/high power field in the experiment group and 65 ± 8/high power field in the control group(P < 0.05).The total number of positive cells was 29 ± 7/high power field in the experimental group and 13 ± 2/high power field in the control group.The albumin expres-sion level was also higher in the experimental group than in the control group(29 ± 7 vs 13 ± 2,P < 0.05).The total number of crossing points was 156 ± 5/high power field in the experimental group and 53 ± 5/high power field in the control group(P < 0.05).The serum alanine aminotransferase levels in experimental and control groups were measured at different time points(120 ± 40 vs 118.50 ± 1.75,P > 0.05;80.60 ± 6.50 vs 101.08 ± 5.67,P < 0.05;50.74 ± 5.38 vs 80.47 ± 4.62,P < 0.05;30.54 ± 2.70 vs 60.72 ± 4.37,P < 0.05;30.77 ± 5.36 vs 40.47 ± 6.50,P < 0.05).At the same time,the serum aspartate aminotransferase levels were measured in experimental and control groups at different time points(122.55 ± 1.46 vs 120.70 ± 4.22,P > 0.05;54.26 ± 6.50 vs 98.70 ± 8.20,P < 0.05;39.47 ± 5.39 vs 78.34 ± 4.50,P < 0.05;28.94 ± 2.70 vs 56.44 ± 4.28,P < 0.05;30.77 ± 5.45 vs 42.50 ± 6.28,P < 0.05).CONCLUSION:SDF-1 can promote the migration of BMMC to the liver of mice with acute liver failure. | Shi-Zhu Jin Xiang-Wei Meng Ming-Zi Han Xun Sun Li-Ying Sun Bing-Rong Liu | 2009 | World Journal of Gastroenterology2009,15,21: | 10 |
| 4 | Protective effects of a novel drug RC28-E blocking both VEGF and FGF2 on early diabetic rat retina显示文摘AIM: To investigate protective effects of a novel recombinant decoy receptor drug RC28-E on retinal damage in early diabetic rats.METHODS: The streptozotocin(STZ)-induced diabetic rats were randomly divided into 6 groups: diabetes mellitus(DM) group(saline, 3 μL/eye); RC28-E at low(0.33 μg/μL, 3 μL), medium(1 μg/μL, 3 μL), and high(3 μg/μL,3 μL) dose groups; vascular endothelial growth factor(VEGF) Trap group(1 μg/μL, 3 μL); fibroblast growth factor(FGF) Trap group(1 μg/μL, 3 μL). Normal control group was included. At week 1 and 4 following diabetic induction,the rats were intravitreally injected with the corresponding solutions. At week 6 following the induction, apoptosis in retinal vessels was detected by TUNEL staining.Glial fibrillary acidic protein(GFAP) expression was examined by immunofluorescence. Blood-retinal barrier(BRB) breakdown was assessed by Evans blue assay.Ultrastructural changes in choroidal and retinal vessels were analyzed by transmission electron microscopy(TEM).Content of VEGF and FGF proteins in retina was measured by enzyme linked immunosorbent assay(ELISA). The retinal expression of intercellular cell adhesion molecule-1(ICAM-1), tumor necrosis factor-α(TNF-α), VEGF and FGF genes was examined by quantitative polymerase chain reaction(qPCR).RESULTS: TUNEL staining showed that the aberrantly increased apoptotic cells death in diabetic retinal vascular network was significantly reduced by treatments of medium and high dose RC28-E, VEGF Trap, and FGF Trap(all P<0.05), the effects of medium and high dose RC28-E or FGF Trap were greater than VEGF Trap(P<0.01). GFAP staining suggested that reactive gliosis was substantially inhibited in all RC28-E and VEGF Trap groups, but the inhibition in FGF Trap group was not as prominent.Evans blue assay demonstrated that only high dose RC28-E could significantly reduce vascular leakage in early diabetic retina(P<0.01). TEM revealed that the ultrastructures in choroidal and retinal vessels were damaged in early diabetic retina, which was ameliorated to differential extents by each drug. The expression of VEGF and FGF2 proteins was significantly upregulated in early diabetic retina, and normalized by RC28-E at all dosages and by the corresponding Traps. The upregulation of ICAM-1 and TNF-α in diabetic retina was substantially suppressed by RC28-E and positive control drugs.CONCLUSION: Dual blockade of VEGF and FGF2 by RC28-E generates remarkable protective effects, including anti-apoptosis, anti-gliosis, anti-leakage, and improving ultrastructures and proinflammatory microenvironment,in early diabetic retina, thereby supporting further development of RC28-E into a novel and effective drug to diabetic retinopathy(DR). | Qian-Hui Yang Yan Zhang Jing Jiang Mian-Mian Wu Qian Han Qi-Yu Bo Guang-Wei Yu Yu-Sha Ru Xun Liu Min Huang Ling Wang Xiao-Min Zhang Jian-Min Fang Xiao-Rong Li | 2018 | International Journal of Ophthalmology(English edition)2018,11,6: | 9 |
| 5 | Phase I study of CAR-T cells with PD-1 and TCR disruption in mesothelin-positive solid tumors显示文摘Programmed cell death protein-1(PD-1)-mediated immunosuppression has been proposed to contribute to the limited clinical efficacy of chimeric antigen receptor T(CAR-T)cells in solid tumors.We generated PD-1 and T cell receptor(TCR)deficient mesothelin-specific CAR-T(MPTK-CAR-T)cells using CRISPR-Cas9 technology and evaluated them in a dose-escalation study.A total of 15 patients received one or more infusions of MPTK-CAR-T cells without prior lymphodepletion.No dose-limiting toxicity or unexpected adverse events were observed in any of the 15 patients.The best overall response was stable disease(2/15 patients).Circulating MPTK-CAR-T cells peaked at days 7–14 and became undetectable beyond 1 month.TCR-positive CAR-T cells rather than TCR-negative CAR-T cells were predominantly detected in effusion or peripheral blood from three patients after infusion.We further confirmed the reduced persistence of TCR-deficient CAR-T cells in animal models.Our results establish the preliminary feasibility and safety of CRISPR-engineered CAR-T cells with PD-1 disruption and suggest that the natural TCR plays an important role in the persistence of CAR-T cells when treating solid tumors. | Zhenguang Wang Na Li Kaichao Feng Meixia Chen Yan Zhang Yang Liu Qingming Yang Jing Nie Na Tang Xingying Zhang Chen Cheng Lianjun Shen Jiaping He Xun Ye Wei Cao Haoyi Wang Weidong Han | 2021 | Cellular & Molecular Immunology2021,18,9: | 7 |
| 6 | Sodium butyrate protects against toxin-induced acute liver failure in rats显示文摘BACKGROUND: Acute liver failure(ALF) is a serious clinical syndrome with high mortality. Sodium butyrate has been shown to alleviate organ injury in a wide variety of preclinical models of critical diseases. The aim of this study was to investigate the protective effect of sodium butyrate on ALF in rats.METHODS: All rats were randomly divided into control,model and sodium butyrate treatment groups. Except the control group, the rats were induced ALF animal model by subcutaneous injection of human serum albumin+D- galactosamine+lipopolysaccharide. After induction of ALF,the rats in the treatment group received sodium butyrate(500mg/kg) at 12-hour or 24-hour time point. Fourty-eight hours after ALF induction, the animals were sacrificed and samples were harvested. Serum endotoxin, high mobility group box-1(HMGB1), liver function parameters, tumor necrosis factoralpha(TNF-α) and interferon-gamma(IFN-γ) were measured.The expression of HMGB1 and nuclear factor-kappa B(NF-κB)p65 protein in liver tissue was detected by Western blotting. The histological changes of liver and intestine were examined. The survival duration was also observed.RESULTS: Serum endotoxin, alanine aminotransferase, HMGB1,TNF-α and IFN-γ were significantly increased and the liver histology showed more severe histopathological injury in the model group compared with the control group(P<0.05).Compared to the model group, sodium butyrate treatment significantly improved the histopathological changes in the liver and intestine, reduced serum endotoxin and inflammatory cytokines, suppressed HMGB1 and NF-кB p65 proteins in liver tissue, and prolonged the survival duration regardless of treatment at 12 hours or 24 hours after induction of ALF(P<0.05).CONCLUSIONS: Sodium butyrate protected the liver from toxin-induced ALF in rats. The mechanisms may be due to direct hepatoprotection and decreased intestinal permeability. | Fan Yang Li-Kun Wang Xun Li Lu-Wen Wang Xiao-Qun Han Zuo-Jiong Gong | 2014 | Hepatobiliary & Pancreatic Diseases International2014,13,3: | 6 |
| 7 | Accuracy of triage strategies for human papillomavirus DNA-positive women in low-resource settings:A cross-sectional study in China显示文摘Objective: Care HPV is a human papillomavirus(HPV) DNA test for low-resource settings(LRS).This study assesses optimum triage strategies for care HPV-positive women in LRS.Methods: A total of 2,530 Chinese women were concurrently screened for cervical cancer with visual inspection with acetic acid(VIA),liquid-based cytology and HPV testing by physician-and self-collected care HPV,and physician-collected Hybrid Capture 2(HC2).Screen-positive women were referred to colposcopy with biopsy and endocervical curettage as necessary.HPV-positivity was defined as ≥1.0 relative light units/cutoff(RLU/CO) for both care HPV and HC2.Primary physician-HC2,physician-care HPV and self-care HPV and in sequential screening with cytology,VIA,or increased HPV test-positivity performance,stratified by age,were assessed for cervical intraepithelial neoplasia(CIN) grade 2/3 or worse(CIN2/3+) detection.Results: The sensitivities and specificities of primary HPV testing for CIN2+ were: 83.8%,88.1% for physiciancare HPV; 72.1%,88.2% for self-care HPV; and 97.1%,86.0% for HC2.Physician-care HPV test-positive women with VIA triage had a sensitivity of 30.9% for CIN2+ versus 80.9% with cytology triage.Self-care HPV testpositive women with VIA triage was 26.5% versus 66.2% with cytology triage.The sensitivity of HC2 test-positive women with VIA triage was 38.2% versus 92.6% with cytology triage.The sensitivity of physician-care HPV testing for CIN2+ decreased from 83.8% at ≥1.0 RLU/CO to 72.1% at ≥10.00 RLU/CO,while the sensitivity of selfcare HPV testing decreased from 72.1% at ≥1.0 RLU/CO to 32.4% at ≥10.00 RLU/CO; similar trends were seen with age-stratification.Conclusions: VIA and cytology triage improved specificity for CIN2/3 than no triage.Sensitivity with VIA triage was unsuitable for a mass-screening program.VIA provider training might improve this strategy.Cytology triage could be feasible where a high-quality cytology program exists.Triage of HPV test-positive women by increased test positivity cutoff adds another LRS triage option. | Margaret Wang Shangying Hu Shuang Zha o Wenhua Zhang Qinjing Pan Xun Zhang FengChen Jinxiu Han Junfei Ma Jennifer S.Smith Youlin Qiao Caihong Zhou Fanghui Zhao | 2017 | Chinese Journal of Cancer Research2017,29,6: | 6 |
| 8 | FeTe1-xSex monolayer films: towards the realization of high-temperature connate topological superconductivity显示文摘We performed angle-resolved photoemission spectroscopy studies on a series of FeTe_(1-x)Se_x monolayer films grown on Sr TiO_3.The superconductivity of the films is robust and rather insensitive to the variations of the band position and effective mass caused by the substitution of Se by Te.However,the band gap between the electron-and hole-like bands at the Brillouin zone center decreases towards band inversion and parity exchange,which drive the system to a nontrivial topological state predicted by theoretical calculations.Our results provide a clear experimental indication that the FeTe_(1-x)Se_x monolayer materials are high-temperature connate topological superconductors in which band topology and superconductivity are integrated intrinsically. | Xun Shi Zhi-Qing Han Pierre Richard Xian-Xin Wu Xi-Liang Peng Tian Qian Shan-Cai Wang Jiang-Ping Hu Yu-Jie Sun Hong Ding | 2017 | Science Bulletin2017,62,7: | 6 |
| 9 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,3: | 6 |
| 10 | Collagen derived species-specific peptides for distinguishing donkey-hide gelatin(Asini Corii Colla)显示文摘Objective:As an important food therapy product with traditional Chinese medicine(TCM) applications,donkey-hide gelatin(Asini Corii Colla,ACC) has been used for thousands of years.However,till now few effective strategy had been proposed to distinguish ACC from other animal hide gelatins,especially closely related horse-and mule-hide gelatins,which was an embarrassment of ACC quality control.Methods:Combined mass spectrometry and bioinformatic methods have been applied to identify and verify two ACC-specific peptides(Pep-1 and Pep-2) capable of distinguishing ACC from other closely related animal gelatins with high selectivity.Results:It confirmed that these two peptides could be not only used for distinguishing ACC from highly homologous horse-hide and mule-hide gelatins as well as other animal hide gelatins.Conclusion:The present study provides a simple method for species-specific peptides discovery,which can be used for assessing the quality of animal gelatin products,and ensure they are authenticable and traceable. | Shuo Cai Ke-xuan Zhao Meng-tong Jiang Shu-ying Han Yun-feng Zheng Xun Liu Ming Zhao Jin-ao Duan Rui Liu | 2021 | Chinese Herbal Medicines2021,13,2: | 5 |
| 11 | Five‑year outcomes of EVO implantable collamer lens implantation for the correction of high myopia and super high myopia显示文摘Background:To evaluate the long-term safety,efficacy,predictability,and stability of implantable collamer lens with a central hole(EVO ICL)implantation for correcting high myopia(HM)and super high myopia(SHM).Methods:This prospective study evaluated 83 eyes of 46 patients who were divided into groups based on their spherical equivalent refractive error(SE):HM group(−12 D≤SE<−6 D)and SHM group(SE<−12 D).They were followed up for 5 years after ICL implantation;assessments of uncorrected distance visual acuity(UDVA),corrected distance visual acuity(CDVA),manifest refractive error,axial length,intraocular pressure,corneal endothelial cell density,and vault were conducted,and a questionnaire was administered.ResuIts:At 5 years postoperatively,the safety indices of the HM and SHM groups were 1.03±0.10 and 1.32±0.39,and the efficacy indices were 0.83±0.25 and 0.86±0.32,respectively.In the HM group,60.47%and 79.07%of the eyes were within±0.50 D and±1.00 D of the attempted correction,while it was achieved for 22.50%and 47.50%of the eyes in the SHM group,respectively.The SE of the HM group decreased from−9.72±1.41 D preoperatively to 0.04±0.39 D 1 month postoperatively and−0.67±0.57 D 5 years postoperatively,while in the SHM group,it decreased from−15.78±3.06 D preoperatively to−0.69±0.97 D 1 month postoperatively and−1.74±1.19 D 5 years postoperatively.Conclusion:EVO ICL implantation is safe,effective,and predictable for correcting HM and SHM.CDVA improved more after surgery for SHM,but the growth of axial length still needs attention. | Xun Chen Xuanqi Wang Yilin Xu Mingrui Cheng Tian Han LingLing Niu Xiaoying Wang Xingtao Zhou | 2021 | Eye and Vision2021,8,1: | 4 |
| 12 | Cancer stem cells:therapeutic implications and perspectives in cancer therapy显示文摘The cancer stem cell(CSC)theory is gaining increasing attention from researchers and has become an important focus of cancer research.According to the theory,a minority population of cancer cells is capable of self-renewal and generation of differentiated progeny,termed cancer stem cells(CSCs).Understanding the properties and characteristics of CSCs is key to future study on cancer research,such as the isolation and identification of CSCs,the cancer diagnosis,and the cancer therapy.Standard oncology treatments,such as chemotherapy,radiotherapy and surgical resection,can only shrink the bulk tumor and the tumor tends to relapse.Thus,therapeutic strategies that focus on targeting CSCs and their microenvironmental niche address the ineffec-tiveness of traditional cancer therapies to eradicate the CSCs that otherwise result in therapy resistance.The combined use of traditional therapies with targeted CSC-specific agents may target the whole cancer and offer a promising strategy for lasting treatment and even cure. | Lu Han Sanjun Shi Tao Gong Zhirong Zhang Xun Sun | 2013 | Acta Pharmaceutica Sinica B2013,3,2: | 4 |
| 13 | Random Fuzzy Chance-constrained Programming Based on Adaptive Chaos Quantum Honey Bee Algorithm and Robustness Analysis显示文摘This paper proposes an adaptive chaos quantum honey bee algorithm (CQHBA) for solving chance-constrained programming in random fuzzy environment based on random fuzzy simulations. Random fuzzy simulation is designed to estimate the chance of a random fuzzy event and the optimistic value to a random fuzzy variable. In CQHBA, each bee carries a group of quantum bits representing a solution. Chaos optimization searches space around the selected best-so-far food source. In the marriage process, random interferential discrete quantum crossover is done between selected drones and the queen. Gaussian quantum mutation is used to keep the diversity of whole population. New methods of computing quantum rotation angles are designed based on grads. A proof of convergence for CQHBA is developed and a theoretical analysis of the computational overhead for the algorithm is presented. Numerical examples are presented to demonstrate its superiority in robustness and stability, efficiency of computational complexity, success rate, and accuracy of solution quality. CQHBA is manifested to be highly robust under various conditions and capable of handling most random fuzzy programmings with any parameter settings, variable initializations, system tolerance and confidence level, perturbations, and noises. | Han Xue Xun Li Hong-Xu Ma College of Electromechanical Engineering and Automation, National University of Defense Technology, Changsha 410073, PRC | 2010 | International Journal of Automation and computing2010,7,1: | 3 |
| 14 | Evaluating the efficacy of endoscopic sphincterotomy on biliary-type sphincter of Oddi dysfunction: A retrospective clinical trial显示文摘BACKGROUND Although endoscopic sphincterotomy(EST)has a positive therapeutic effect on biliary-type sphincter of Oddi dysfunction(SOD),some patients still have little relief after EST,which implies that other functional abdominal pain may also be present with biliary-type SOD and interfere with the diagnosis and treatment of it.AIM To retrospectively assess EST as a treatment for biliary-type SOD and analyze the importance of functional gastrointestinal disorder(FGID)in guiding endoscopic treatment of SOD.METHODS Clinical data of 79 patients with biliary-type SOD(type I and type II)treated with EST at Affiliated Hospital of Guizhou Medical University from January 2014 to January 2019 were retrospectively collected to evaluate the clinical therapeutic effect of EST.The significance of relationship between FGID and biliary-type SOD was analyzed.RESULTS Seventy-nine patients with biliary-type SOD received EST,including 29 type 1 patients and 50 type 2 patients.The verbal rating scale-5(VRS-5)scores before EST were all 3 or 4 points,and the scores decreased after EST;the difference was statistically significant(P<0.05).After EST,the serum indexes of alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin in biliary-type SOD were significantly lower than before(P<0.05).After EST,67(84.8%)and 8(10.1%)of the 79 patients with biliary-type SOD had obviously effective(VRS-5=0 points)and effective treatment(VRS-5=1-2 points),with an overall effectiveness rate of 94.9%(75/79).There was no difference in VRS-5 scores between biliary-type SOD patients with or without FGID before EST(P>0.05).Of 12 biliary-type SOD(with FGID)patients,11 had abdominal pain after EST;of 67 biliary-type SOD(without FGID)patients,0 had abdominal pain after EST.The difference was statistically significant(P<0.05).The 11 biliary-type SOD(with FGID)patients with recurrence of symptoms,the recurrence time was about half a year after the EST,and the symptoms were significantly relieved after regular medical treatment.There were 4 cases of postendoscopic retrograde cholangiopancreatography pancreatitis(5.1%),and no cholangitis,bleeding or perforation occurred.Patients were followed up for 1 year to 5 years after EST,with an average follow-up time of 2.34 years,and there were no long-term adverse events such as sphincter of Oddi restenosis or cholangitis caused by intestinal bile reflux during the follow-up.CONCLUSION EST is a safe and effective treatment for SOD.For patients with type I and II SOD combined with FGID,single EST or medical treatment has limited efficacy.It is recommended that EST and medicine be combined to improve the cure rate of such patients. | Li-Kun Ren Zhi-Yuan Cai Xun Ran Neng-Hong Yang Xing-Zhi Li Hao Liu Chang-Wei Wu Wen-Ying Zeng Min Han | 2021 | World Journal of Clinical Cases2021,9,32: | 3 |

| 16 | Protein microarray analysis of cytokine expression changes in distal stumps after sciatic nerve transection显示文摘A large number of chemokines,cytokines,other trophic factors and the extracellular matrix molecules form a favorable microenvironment for peripheral nerve regeneration.This microenvironment is one of the major factors for regenerative success.Therefore,it is important to investigate the key molecules and regulators affecting nerve regeneration after peripheral nerve injury.However,the identities of specific cytokines at various time points after sciatic nerve injury have not been determined.The study was performed by transecting the sciatic nerve to establish a model of peripheral nerve injury and to analyze,by protein microarray,the expression of different cytokines in the distal nerve after injury.Results showed a large number of cytokines were up-regulated at different time points post injury and several cytokines,e.g.,ciliary neurotrophic factor,were downregulated.The construction of a protein-protein interaction network was used to screen how the proteins interacted with differentially expressed cytokines.Kyoto Encyclopedia of Genes and Genomes pathway and Gene ontology analyses indicated that the differentially expressed cytokines were significantly associated with chemokine signaling pathways,Janus kinase/signal transducers and activators of transcription,phosphoinositide 3-kinase/protein kinase B,and notch signaling pathway.The cytokines involved in inflammation,immune response and cell chemotaxis were up-regulated initially and the cytokines involved in neuronal apoptotic processes,cell-cell adhesion,and cell proliferation were up-regulated at 28 days after injury.Western blot analysis showed that the expression and changes of hepatocyte growth factor,glial cell line-derived neurotrophic factor and ciliary neurotrophic factor were consistent with the results of protein microarray analysis.The results provide a comprehensive understanding of changes in cytokine expression and changes in these cytokines and classical signaling pathways and biological functions during Wallerian degeneration,as well as a basis for potential treatments of peripheral nerve injury.The study was approved by the Institutional Animal Care and Use Committee of the Chinese PLA General Hospital,China(approval number:2016-x9-07)in September 2016. | Xiao-Qing Cheng Xue-Zhen Liang Shuai Wei Xiao Ding Gong-Hai Han Ping Liu Xun Sun Qi Quan He Tang Qing Zhao Ai-Jia Shang Jiang Peng | 2020 | Neural Regeneration Research2020,15,3: | 2 |
| 17 | Photonic integrated spiking neuron chip based on a self-pulsating DFB laser with a saturable absorber显示文摘We proposed and experimentally demonstrated a simple and novel photonic spiking neuron based on a distributed feedback(DFB)laser chip with an intracavity saturable absorber(SA).The DFB laser with an intracavity SA(DFBSA)contains a gain region and an SA region.The gain region is designed and fabricated by the asymmetric equivalentπ-phase shift based on the reconstruction-equivalent-chirp technique.Under properly injected current in the gain region and reversely biased voltage in the SA region,periodic self-pulsation was experimentally observed due to the Q-switching effect.The self-pulsation frequency increases with the increase of the bias current and is within the range of several gigahertz.When the bias current is below the self-pulsation threshold,neuronlike spiking responses appear when external optical stimulus pulses are injected.Experimental results show that the spike threshold,temporal integration,and refractory period can all be observed in the fabricated DFB-SA chip.To numerically verify the experimental findings,a time-dependent coupled-wave equation model was developed,which described the physics processes inside the gain and SA regions.The numerical results agree well with the experimental measurements.We further experimentally demonstrated that the weighted sum output can readily be encoded into the self-pulsation frequency of the DFB-SA neuron.We also benchmarked the handwritten digit classification task with a simple single-layer fully connected neural network.By using the experimentally measured dependence of the self-pulsation frequency on the bias current in the gain region as an activation function,we can achieve a recognition accuracy of 92.2%,which bridges the gap between the continuous valued artificial neural networks and spike-based neuromorphic networks.To the best of our knowledge,this is the first experimental demonstration of a photonic integrated spiking neuron based on a DFB-SA,which shows great potential to realizing large-scale multiwavelength photonic spiking neural network chips. | YUECHUN SHI SHUIYING XIANG XINGXING GUO YAHUI ZHANG HONGJI WANG DIANZHUANG ZHENG YUNA ZHANG YANAN HAN YONG ZHAO XIAOJUN ZHU XIANGFEI CHEN XUN LI YUE HAO | 2023 | Photonics Research2023,11,8: | 2 |
| 18 | Nature inspired hierarchical structures in nano-cellular epoxy/graphene-Fe3O4 nanocomposites with ultra-efficient EMI and robust mechanical strength显示文摘Hierarchical layered structures,whether in a compact form like nacre or a porous manner like bone,are well known for their combined features of high stiffness,strength,and lightweight,inspiring many man-made materials and structures for high performance applications.The use of nacre/bone like hierarchical structures in polymer nanocomposites can achieve excellent mechanical and functional properties with high filler volume fractions after carefully aligning functional nanofillers,although the fabrication and processing remain a great challenge.In this work,a bio-inspired lightweight nano-cellular epoxy/graphene-Fe_(3)O_(4) nanocomposite with high nanofiller loading of 75 wt.%was successfully fabricated by combining features from both nacre and bone structures,via a simple compression molding process together with an eco-friendly supercritical CO_(2) foaming process to achieve robust mechanical strength and excellent electromagnetic interference(EMI)shielding effectiveness(SE)simultaneously.Highly aligned graphene-Fe_(3)O_(4) nanoplatelets with well controlled nanoscale porous structures(52.6 nm)enabled both low density(1.26 g/cm^(3))and high specific EMI SE>5200 dB/cm^(2)/g,as well as preserved tensile strength of 67 MPa.This study provides a sustainable route to fabricate nature mimicked structures with high performance and high flexibility for a wide range of applications,from portable electronics to healthcare devices. | Xun Fan Fengchao Wang Qiang Gao Yu Zhang Fei Huang Ronglin Xiao Jianbin Qin Han Zhang Xuetao Shi Guangcheng Zhang | 2022 | Journal of Materials Science & Technology2022,,8: | 2 |

| 20 | Roles of furfural during the thermal treatment of bio-oil at low temperatures显示文摘The reactive O-containing species in bio-oil could induce the polymerization of bio-oil during its thermal treatment, which affects the relevant utilization of bio-oil significantly. Furans, as the highly reactive Ocontaining species in bio-oil, play important roles during the thermal treatment of bio-oil. In this study,furfural was chosen as the representative of the furans in bio-oil to investigate its roles during the thermal treatment of bio-oil. The raw bio-oil with and without the addition of extra furfural(10 wt% of bio-oil) and pure furfural were pyrolyzed in a fixed-bed reactor at 200–500 ℃. The results show that the interactions among furfural and bio-oil components can take place prior to the evaporation of furfural(<140 ℃) to form the intermediates, then these intermediates could be further polymerized to form large molecular compounds, and coke can be formed via the interactions at temperatures ≥ 300 ℃. At temperatures ≤ 300 ℃, furfural mainly interacts with anhydrosugars. As the temperature further increases, the aromatics are involved in the interactions to form coke. The increased percentage of the coke formed via the interactions is in a linear relation with the conversion of furfural during the pyrolysis at 300–500 ℃(no coke formed at 200 ℃). Meanwhile, more non-aromatic light components(≤ C6) and less aromatics in the tars could be formed due to the interactions. | Zhe Xiong Yuanjing Chen Muhammad Mufti Azis Xun Hu Wei Deng Hengda Han Long Jiang Sheng Su Song Hu Yi Wang Jun Xiang | 2020 | Journal of Energy Chemistry2020,29,11: | 2 |
