1Ganoderic acid hinders renal fibrosis via suppressing the TGF- β/Smad and MAPK signaling pathways显示文摘Renal fibrosis is considered as the pathway of almost all kinds of chronic kidney diseases(CKD)to the end stage of renal diseases(ESRD).Ganoderic acid(GA)is a group of lanostane triterpenes isolated from Ganoderma lucidum,which has shown a variety of pharmacological activities.In this study we investigated whether GA exerted antirenal fibrosis effect in a unilateral ureteral obstruction(UUO)mouse model.After UUO surgery,the mice were treated with GA(3.125,12.5,and 50 mg·kg^−1·d^−1,ip)for 7 or 14 days.Then the mice were sacrificed for collecting blood and kidneys.We showed that GA treatment dose-dependently attenuated UUO-induced tubular injury and renal fibrosis;GA(50 mg·kg^−1·d^−1)significantly ameliorated renal disfunction during fibrosis progression.We further revealed that GA treatment inhibited the extracellular matrix(ECM)deposition in the kidney by suppressing the expression of fibronectin,mainly through hindering the over activation of TGF-β/Smad signaling.On the other hand,GA treatment significantly decreased the expression of mesenchymal cell markers alpha-smooth muscle actin(α-SMA)and vimentin,and upregulated E-cadherin expression in the kidney,suggesting the suppression of tubular epithelial-mesenchymal transition(EMT)partially via inhibiting both TGF-β/Smad and MAPK(ERK,JNK,p38)signaling pathways.The inhibitory effects of GA on TGF-β/Smad and MAPK signaling pathways were confirmed in TGF-β1-stimulated HK-2 cell model.GA-A,a GA monomer,was identified as a potent inhibitor on renal fibrosis in vitro.These data demonstrate that GA or GA-A might be developed as a potential therapeutic agent in the treatment of renal fibrosis.Xiao-qiang Geng Ang Ma Jin-zhao He Liang Wang Ying-li Jia Guang-ying Shao Min Li Hong Zhou Shu-qian Lin Jian-hua Ran Bao-xue Yang 2020Acta Pharmacologica Sinica2020,41,5:43
2Output Waveform Analysis of an Electro-hydraulic Vibrator Controlled by the Multiple Valves显示文摘The existing research of the electro-hydraulic vibrator mainly focuses on system stability,working frequency width and output waveform distortion.However,this high frequency performance of the electro-hydraulic vibrator is difficult to be improved greatly due to fast insufficiently frequency response of the servo valve itself and limited compensation capability of the control structure in the vibrator system.In this paper,to realize high frequency vibration,an improved two-dimensional valve(here within defined as a2D valve)as a main control component is adopted to the parallel connection with a servo valve to control the electro-hydraulic vibrator.Because the output waveforms of this electro-hydraulic vibrator are incapable to be verified through timely feedback as in the conventional electro-hydraulic servo system,the analysis to the output waveform becomes crucial to the design and control of the electro-hydraulic vibrator.The mathematical models of hydraulic actuation mechanism and the orifice area of the parallel valves connection are established first.And then the vibration process is divided into two sections in terms of the direction of the flow,the analytical expression of the excited waveform is solved.Based on the analytical results,the vibration boundary positions and the relationships exist between working states and the control parameters are derived.Finally an experimental system was built to validate the theoretical analysis.It is verified that this electro-hydraulic vibration system could achieve high working frequency,up to 2 000 Hz.The excited waveform is similar to the sinusoidal waveform.And the ascent and decent slopes of the waveforms are somewhat asymmetrical.This asymmetry is not only caused by the change of the direction of the elastic force but also dependent on the bias position of the vibration.Consequently the distortion of effective working waveform is less than 10%.This electro-hydraulic vibrator controlled by the multiple valves could not only greatly enhance the working frequency but also precisely control the vibration characteristic variables such as waveform shape.REN Yan RUAN Jian JIA Wen'ang 2014Chinese Journal of Mechanical Engineering2014,27,1:10
3Inhibiting autophagy enhances sulforaphane-induced apoptosis via targeting NRF2 in esophageal squamous cell carcinoma显示文摘Sulforaphane(SFN), a natural anti-tumor compound from cruciferous vegetables, has been reported to induce protective autophagy to cancer cells, which might impair the anti-tumor efficiency of SFN. However, the accurate function and mechanism of SFN inducing autophagy in cancers are still obscure, especially in esophageal squamous cell carcinoma(ESCC), one of malignancies with high incidence in North China. Here, we mainly explored the potential function of autophagy upon SFN treatment in ESCC and molecular mechanism. We demonstrated that SFN could inhibit cell proliferation and induce apoptosis by activating caspase pathway. Moreover, we found activation of NRF2 pathway by SFN was responsible for the induction of autophagy and also a disadvantage element to the anti-tumor effects of SFN on ESCC, indicating that SFN might induce protective autophagy in ESCC. We, therefore,investigated effects of autophagy inhibition on sensitivity of ESCC cells to SFN and found that chloroquine(CQ) could neutralize the activation of SFN on NRF2 and enhance the activation of SFN on caspase pathway, thus improved the anti-tumor efficiency of SFN on ESCC in vitro and in vivo. Our study provides a preclinical rationale for development of SFN and its analogs to the future treatment of ESCC.Zhaoming Lu Yandan Ren Li Yang Ang Jia Yi Hu Yu Zhao Wuduo Zhao Bin Yu Wen Zhao Jianying Zhang Guiqin Hou 2021Acta Pharmaceutica Sinica B2021,11,5:8
4Separate Control of High Frequency Electro-hydraulic Vibration Exciter显示文摘The working frequency of the conventional electro-hydraulic vibration exciters,which consist of a servo valve and a hydraulic cylinder,is generally restricted within a narrow range due to limited frequency response capability of the servo valve itself.To counteract such restriction,a novel scheme for an electro-hydraulic vibrator,controlled by a two-dimensional valve(2D valve) and a bias valve in parallel,is therefore proposed.The frequency,amplitude and offset are independently controlled by rotary speed,axial sliding of the spool of the 2D valve and axial sliding of the spool of the bias valve.The principle of separate control was presented and the regulation approach of frequency,amplitude and offset was discussed.A mathematical model of the hydraulic power mechanism for the proposed vibration exciter was established to investigate the relationship between the amplitude and the axial sliding of the 2D valve' spool,as well as that between the offset and the axial sliding of the bias valve's spool at various frequencies.An experimental system was built to validate the theoretical analysis.It is verified that the 2D exciter is capable of working smoothly in a frequency range of 5- 200 Hz.And its frequency,amplitude and offset can be controlled respectively by either closed loop or open loop method.There is a linear relationship between the output amplitude and the spool axial opening of the 2D valve until a point when the flow rate becomes saturate and the amplitude remains constant.The offset displacement of the cylinder's piston is linearly proportional to the axial displacement of the spool of the bias valve,when the valve opening is less than 25%.Thereafter,the slop of the offset curve decreases and tends to saturate.The proposed electro-hydraulic vibration controlled by the 2D valve not only facilitates the realization of high-frequency electro-hydraulic vibration,the high-accuracy of vibration can also be achieved by means of independent controls to the frequency,amplitude and offset.JIA Wen'ang RUAN Jian REN Yan 2011Chinese Journal of Mechanical Engineering2011,24,2:7
5Evaluation of characteristics of left-sided colorectal perfusion in elderly patients by angiography显示文摘BACKGROUND Handling of the inferior mesenteric artery(IMA)and maintaining anastomotic perfusion are important in radical resection of left-sided colorectal cancer.However,the branching of this artery and the drainage patterns of this vein vary among individuals,and the characteristics and perfusion region of this artery in elderly patients remain unclear.AIM To evaluate the characteristics and perfusion region of the IMA in elderly patients using angiography.METHODS We enrolled 154 patients(>65 years old)who underwent digital subtraction angiography of the IMA.The characteristics,bifurcation,and distribution of the IMA and termination of the anastomotic perfusion of the left colon and rectum were examined using digital subtraction angiography.Collateral arterial arches and the IMA hemoperfusion region were also recorded.Perfusion regions were cross-referenced with clinical and anatomical features by the univariate analysis.RESULTS Of 154 patients,25(16.2%)had IMA lesions.The left colic artery arose independently from the IMA in 44.2%of patients,shared a trunk with the sigmoid artery in 35.1%,shared an opening with the sigmoid and superior rectal arteries in 16.9%,and was absent in 5.1%.The IMA perfusion region stopped at the splenic flexure in 50(32.5%)patients.The collateral circulation existed in the colonic perfusion region,including the marginal artery(Drummond’s artery),the ascending branch of the left colonic artery to supply the transverse colon,and the arc of Riolan with a frequency of 100%,22.7%,and 1.9%,respectively.The IMA perfusion region was independently associated with the comorbidity of atherosclerosis,IMA atherosclerotic lesion,branching pattern,collateral circulation,and marginal artery integrity.CONCLUSION The IMA and its branches are prone to arteriosclerosis,and IMA perfusion may be interrupted at the splenic flexure in elderly patients.The applicability and precision of preoperative angiography for evaluating the IMA branching and perfusion patterns could facilitate geriatric laparoscopic left-sided colorectal cancer surgery with suspicion of poor IMA perfusion.Chao Zhang Ang Li Tao Luo Yu Li Fei Li Jia Li 2020World Journal of Gastroenterology2020,26,24:7
6Proton pump inhibitor use increases mortality and hepatic decompensation in liver cirrhosis显示文摘BACKGROUND Proton pump inhibitors(PPIs)are widely prescribed,often without clear indications.There are conflicting data on its association with mortality risk and hepatic decompensation in cirrhotic patients.Furthermore,PPI users and PPI exposure in some studies have been poorly defined with many confounding factors.AIM To examine if PPI use increases mortality and hepatic decompensation and the impact of cumulative PPI dose exposure.METHODS Data from patients with decompensated liver cirrhosis were extracted from a hospital database between 2013 to 2017.PPI users were defined as cumulative defined daily dose(cDDD)≥28 within a landmark period,after hospitalisation for hepatic decompensation.Cox regression analysis for comparison was done after propensity score adjustment.Further risk of hepatic decompensation was analysed by Poisson regression.RESULTS Among 295 decompensated cirrhosis patients,238 were PPI users and 57 were non-users.PPI users had higher mortality compared to non-users[adjusted HR=2.10,(1.20-3.67);P=0.009].Longer PPI use with cDDD>90 was associated with higher mortality,compared to non-users[aHR=2.27,(1.10-5.14);P=0.038].PPI users had a higher incidence of hospitalization for hepatic decompensation[aRR=1.61,(1.30-2.11);P<0.001].CONCLUSION PPI use in decompensated cirrhosis is associated with increased risk of mortality and hepatic decompensation.Longer PPI exposure with cDDD>90 increases the risk of mortality.Marianne Anastasia De Roza Lim Kai Jia Wen Kam Yiong Huak Chan Andrew Kwek Tiing Leong Ang John Chen Hsiang 2019World Journal of Gastroenterology2019,25,33:6
7Optimal immunosuppressor induces stable gut microbiota after liver transplantation显示文摘AIM To study the influence of different doses of tacrolimus(FK506)on gut microbiota after liver transplantation(LT)in rats.METHODS Specific pathogen-free Brown Norway(BN)rats and Lewis rats were separated into five groups:(1)Tolerance group(BN-BN LT,n=8);(2)rejection group(Lewis-BN LT,n=8);(3)high dosage FK506(FK506-H)group(Lewis-BN LT,n=8);(4)middle dosage FK506(FK506-M)group(Lewis-BN LT,n=8);and(5)low dosage FK506(FK506-L)group(LewisBN LT,n=8).FK506 was administered to recipients at a dose of 1.0 mg/kg,0.5 mg/kg,and 0.1 mg/kg body weight for 29 d after LT to the FK506-H,FK506-M,and FK506-L groups,respectively.On the 30^(th) day after LT,all rats were sampled and euthanized.Blood samples were harvested for liver function and plasma endotoxin testing.Hepatic graft and ileocecal tissues were collected for histopathology observation.Ileocecal contents were used for DNA extraction,Real-time quantitative polymerase chain reaction(RT-PCR)and digital processing of denaturing gradient gel electrophoresis(DGGE)profiles and analysis.RESULTS Compared to the FK506-H and FK506-L groups,FK506-M was optimal for maintaining immunosuppression and inducing normal graft function;the FK506-M maintained gut barrier integrity and low plasma endotoxin levels;furthermore,DGGE results showed that FK506-M induced stable gut microbiota.Diversity analysis indicated that FK506-M increased species richness and rare species abundance,and cluster analysis confirmed the stable gut microbiota induced by FK506-M.Phylogenetic tree analysis identified crucial bacteria associated with FK506-M;seven of the nine bacteria that were decreased corresponded to Bacteroidetes,while increased bacteria were of the Bifidobacterium species.FK506-M increased Faecalibacterium prausnitzii and Bifidobacterium spp.and decreased Bacteroides-Prevotella and Enterobacteriaceae,as assessed by RT-PCR,which confirmed the crucial bacterial alterations identified through DGGE.CONCLUSION Compared to the low or high dosage of FK506,an optimal dosage of FK506 induced immunosuppression,normal graft function and stable gut microbiota following LT in rats.The stable gut microbiota presented increased probiotics and decreased potential pathogenic endotoxin-producing bacteria.These findings provide a novel strategy based on gut microbiota for immunosuppressive dosage assessment for recipients following LT.Jian-Wen Jiang Zhi-Gang Ren Hai-Feng Lu Hua Zhang Ang Li Guang-Ying Cui Jun-Jun Jia Hai-Yang Xie Xin-Hua Chen Yong He Li Jiang Lan-Juan Li 2018World Journal of Gastroenterology2018,24,34:5
8Infection recurrence following minimally invasive treatment in patients with infectious pancreatic necrosis显示文摘BACKGROUND In recent decades,an increasing number of patients have received minimally invasive intervention for infected pancreatic necrosis(IPN)because of the benefits in reducing postoperative multiple organ failure and mortality.However,there are limited published data regarding infection recurrence after treatment of this patient population.AIM To investigate the incidence and prediction of infection recurrence following successful minimally invasive treatment in IPN patients.METHODS Medical records for 193 IPN patients,who underwent minimally invasive treatment between February 2014 and October 2018,were retrospectively reviewed.Patients,who survived after the treatment,were divided into two groups:one group with infection after drainage catheter removal and another group without infection.The morphological and clinical data were compared between the two groups.Significantly different variables were introduced into the correlation and multivariate logistic analysis to identify independent predictors for infection recurrence.Sensitivity and specificity for diagnostic performance were determined.RESULTS Of the 193 IPN patients,178 were recruited into the study.Of them,9(5.06%)patients died and 169 patients survived but infection recurred in 13 of 178 patients(7.30%)at 7(4-10)d after drainage catheters were removed.White blood cell(WBC)count,serum C-reactive protein(CRP),interleukin-6,and procalcitonin levels measured at the time of catheter removal were significantly higher in patients with infection than in those without(all P<0.05).In addition,drainage duration and length of the catheter measured by computerized tomography scan were significantly longer in patients with infection(P=0.025 and P<0.0001,respectively).Although these parameters all correlated positively with the incidence of infection(all P<0.05),only WBC,CRP,procalcitonin levels,and catheter length were identified as independent predictors for infection recurrence.The sensitivity and specificity for infection prediction were high in WBC count(≥9.95×109/L)and serum procalcitonin level(≥0.05 ng/mL)but moderate in serum CRP level(cut-off point≥7.37 mg/L).The catheter length(cut-off value≥8.05 cm)had a high sensitivity but low specificity to predict the infection recurrence.CONCLUSION WBC count,serum procalcitonin,and CRP levels may be valuable for predicting infection recurrence following minimally invasive intervention in IPN patients.These biomarkers should be considered before removing the drainage catheters.Chong-Chong Gao Jia Li Feng Cao Xiao-Hui Wang Ang Li Zhe Wang Fei Li 2020World Journal of Gastroenterology2020,26,22:5
9Monolithic integration of MoS2-based visible detectors and GaN-based UV detectors显示文摘With the increasing demand for high integration and multi-color photodetection for both military and civilian applications, the research of multi-wavelength detectors has become a new research hotspot. However, current research has been mainly in visible dual-or multi-wavelength detectors, while integration of both visible light and ultraviolet(UV) dual-wavelength detectors has rarely been studied. In this work, large-scale and high-quality monolayer MoS2 was grown by the chemical vapor deposition method on transparent free-standing GaN substrate. Monolithic integration of MoS2-based visible detectors and GaN-based UV detectors was demonstrated using common semiconductor fabrication technologies such as photolithography, argon plasma etching, and metal deposition. High performance of a 280 nm and 405 nm dual-wavelength photodetector was realized.The responsivity of the UV detector reached 172.12 A/W, while that of the visible detector reached 17.5 A/W.Meanwhile, both photodetectors achieved high photocurrent gain, high external quantum efficiency, high normalized detection rate, and low noise equivalent power. Our study extends the future application of dual-wavelength detectors for image sensing and optical communication.YOU WU ZHIWEN LI KAH-WEE ANG YUPING JIA ZHIMING SHI ZHI HUANG WENJIE YU XIAOJUAN SUN XINKE LIU DABING LI 2019Photonics Research2019,7,10:4

11Clinical study on the surgical treatment of atypical Lisfranc joint complex injury显示文摘BACKGROUND Lisfranc injuries have not received much attention by orthopedic doctors in the past,and there is little related research on the diagnosis and treatment of these injuries.In recent years with the rise in foot and ankle surgery,doctors are now paying more attention to this type of injury.However,there is still a high rate of missed diagnosis due to insufficient attention causing treatment delays or inadequate treatments,which eventually result in greater sequelae;including long-term pain,arthritis,foot deformity etc.In particular,for cases with a mild Lisfranc joint complex injury,the incidence of sequelae is higher.AIM To select an active surgical treatment for an atypical Lisfranc joint complex injury and to evaluate the clinical efficacy of the surgical treatment.METHODS The clinical data of 18 patients,including 10 males and 8 females aged 20-64 years with Lisfranc injuries treated in our department from January 2017 to September 2019 were retrospectively analyzed.All patients were treated with an open reduction and internal fixation method using locking titanium mini-plates and hollow screws or Kirschner wires.X-ray images were taken and follow-up was performed monthly after the operation;the internal fixation was then removed 4-5 mo after the operation;and the American Orthopedic Foot and Ankle Society(AOFAS)score was used for evaluation on the last follow-up.RESULTS All patients were followed up for 6-12 mo.A good/excellent AOFAS score was observed in 88.9%of patients.CONCLUSION For atypical Lisfranc joint complex injuries,active open reduction and internal fixation can be performed to enable patients to obtain a good prognosis and satisfactory functional recovery.Xu Li Le-Sheng Jia Ang Li Xin Xie Jun Cui Guo-Liang Li 2020World Journal of Clinical Cases2020,8,19:2

15Bridging gaps between environmental flows theory and practices in China显示文摘In recent decades,a series of policies and practices for environmental flows(e-flows)have been implemented in China,with the sustainable development goal of balancing the utilization and protection of water resources among social,economic,and ecological needs.The aims of this study were to determine the main challenges and issues in e-flows implementation at different scales by analyzing policies and practices for eflows in China,and to propose some recommendations for bridging the gaps between the science and implementation of e-flows.The gaps between the science and implementation of e-flows were found after review of literature,policies,and practices,and it was found that ecological flow was a more widely used term by the government,rather than e-flows,in implementation.The plans and effects of e-flows implementation are discussed in this paper and challenges of e-flows implementation are recognized:(1)limited water resources and uneven spatial and temporal distribution,(2)a weak scientific basis for e-flows implementation,(3)poor operability of e-flows science,and(4)ineffective supervision and guarantee measures.The recommendations are(1)to strengthen the scientific foundation of e-flows,(2)to improve effectiveness in application of e-flows science,and(3)to propose operable and effective supervision and guarantee measures.This paper elaborates the current understanding of e-flows science and provides practical recommendations for implementing e-flows and for improving the effectiveness in e-flows implementation.To bridge the gaps between science and implementation of e-flows and improve the operability of policies in future practices,more scientific research on practices is recommended through adaptive management.Ang Chen Miao Wu Sai-nan Wu Xin Sui Jing-ya Wen Peng-yuan Wang Lin Cheng Guy R.Lanza Chun-na Liu Wan-lin Jia 2019Water Science and Engineering2019,12,4:1
