1Morphological study on colonic pathology in ulcerative colitis treated by moxibustion显示文摘AIM To observe the therapeutic effect ofmoxibustion on ulcerative colitis and itsinfluence on the colonic mucosal morphology.METHODS Forty-six patients with ulcerativecolitis were randomly divided into themoxibustion with herbal medicine underneathgroup and the western medicine group.Thirtypatients were treated with the abovemoxibustion and 16 patients with Salicylayefapyridine(SASP).The colonic mucosa of 13patients in the moxibustion group was observedby colonoscopy before and after the treatment.Mucin was also analyzed by H.E and AB-PASstaining.RESULTS Seventeen patients were clinicallycured,12 were improved and 1 unchanged in themoxibustion group.In the control group,5patients were clinically cured,7 improved and 4unchanged.Thirteen patients with active UCwere taken as the subjects for histopathologicanalysis in this study.The colonic mucosallesions were remarkably improved and thecharacteristic of the mucin also changed.Inmost sections,the chronic inflammation ofmucosa was geatly ameliorated(P<0.01).Theinflammatory cell infiltratation much decreased and neutrophils,disapeared in most sections(P<0.001).The goblet cells significantlyincreased(P<0.001);crypt paracrypt abscessor mucosal ulceration was seen(P<0.001).CONCLUSION The rate of cure of ulcerative colitis by moxibustion with herbal medicine beneath is superior to that by SASP. This sort of moxibustion can effectively improve the colonic mucosal lesions and restore the proportion of mucoprotein to near normal.Huan Gan Wu Li Bin Zhou Da Ren Shi Shi Min Liu Hui Rong Liu Bi Meng Zhang Han Ping Chen Lin Shan Zhang 2000World Journal of Gastroenterology2000,6,6:28
2A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues.LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of 1999Cell Research1999,9,1:22

4术前肌电图和脑干听觉诱发电位与面肌痉挛微血管减压术后迟发性面瘫发生的关系(英文)显示文摘Background Delayed facial palsy ( DFP) after microvascular decompression ( MVD) in patients with hemifacial spasm ( HFS) is not uncommon,but the cause remains unknown. Objectives To assess whether intraoperative electromyography ( EMG) and brainstem auditory evoked potential ( BAEP) can predict DFP after MVD. Methods Between September 2009 and February 2011 we examined 86 patients,9 of whom ( 10. 4% ) developed DFP after MVD on the same side. All patients underwent MVD and were followed - up for a median period of 13 months ( range 6-22) . We retrospectively examined intraoperative facial EMG and BAEP findings using our MVD patients' registry. We excluded secondary HFS and immediate postoperative facial palsy after MVD in this study. We assessed the prevalence and clinical characteristics of DFP and compared EMG and BAEP findings between DFP and non-DFP groups. Results: All pa- tients recovered completely,with a mean time to recovery of 37. 8 days ( range 22-57) . There were no significant differences between DFP and non - DFP patients in terms of the amplitude and latency of intraoperative EMG and BAEP. Conclusion The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings.Kim HJ Park YS Ryu JS Huh R Han I Shin DA Kim TG Cho KG Chung SS 2012中华神经外科疾病研究杂志2012,11,4:13
5A 12-year cohort study on the efficacy of plasmaderived hepatitis B vaccine in rural newborns显示文摘AIM To understand the anti-HBs persistenceand the long-term preventive efficacy in ruralnewborns after vaccination with plasma-derivedhepatitis B vaccine.METHODS In the time of expanded program onimmunization(EPI),the newborns werevaccinated with 10μg×3 doses of hepatitis Bvaccine and 762 newborns who were HBsAgnegative after primary immunization wereselected for cohort observation from 1986 to1998.Their serum samples were detectedqualitatively and quantitatively for hepatitis Binfecting markers,including HBsAg,anti-HBsand anti-HBc by SPRIA Kits.The annual HBsAgpositive conversion rate was counted by life-table method.RESULTS①The anti-HBs positive rate was94.44% for the babies born to HBsAg negativemothers and 84.21% for those born to HBsAgpositive mothers in the 1st year afterimmunization,and dropped to 51.31% and52.50% in the 12th year respectively.GMT valuewas dropped from 31.62 to 3.13 and 23.99 to 3.65in the 2nd to the 12th year respectively.Therewas a marked drop in GMT at the 3rd to the 5thyear,and in anti-HBs positive rate at the 9th tothe 10th year.②In the period of 12 yearsobservation,the person-year HBsAg positive conversion rates were 0.12%(5/4150.0)innewborns born to HBsAg negative mothers and0.20%(1/508.0)in those born to HBsAgpositive mothers,and none of the HBsAgpositive converted children became HBsAgchronic carriers.Compared with the baselinebefore immunization,the protective rates were97.19% and 95.32% respectively.CONCLUSION The protective efficacy ofplasma-derived hepatitis B vaccine persisted atleast 12 years,and a booster dose seems notnecessary within at least 12 years after theprimary three-doses immunization to newbornsborn to HBsAg negative mothers.Hong Bin Liu Zong Da Meng Jing Chen Ma Chang Quan Han Ying Lin Zhang Zhan Chun Xing Yu Wei Zhang Yu Zhong Liu Hui Lin Cao 2000World Journal of Gastroenterology2000,6,3:11

10A data-driven model predictive control for lighting system based on historical occupancy in an office building: Methodology development显示文摘The lighting system accounts for 8%of the total electricity consumption in commercial buildings in the United States and 12%of the total electricity consumption in public buildings globally.This consumption share can be effectively reduced using the demand-response control.The traditional lighting system control method commonly depends on the real-time occupancy data collected using the passive infrared(PIR)sensor.However,the detection inaccuracy of the PIR sensor usually results in false-offs.To diminish the false-error frequency,the existing lighting system control simply deploys a delayed reaction period(e.g.,5 to 20 min),which is not sufficiently accurate for the demand-response operation.Therefore,in this research,a novel data-driven model predictive control(MPC)method that is based on the temporal sequential-based artificial neural network(TS-ANN)is proposed to overcome this challenge using an updated historical occupancy status.Using an office as case study,the proposed model is also compared with the traditional lighting system control method.In the proposed model,the occupancy data was trained to predict the occupancy pattern to improve the control.It was found that the occupancy prediction mainly correlates with the historical occupancy ratio and the time sequential feature.The simulation results indicated that the proposed method achieved higher accuracy(97.4%)and fewer false-offs(from 79.5 with traditional time delay method to 0.6 times per day)are achieved by the MPC model.The proposed TS-ANN-MPC method integrates the analysis of the occupant behavior routine into on-site control and has the potential to further enhance the control performance practice for maximum energy conservation.Yuan Jin Da Yan Xingxing Zhang Jingjing An Mengjie Han 2021Building Simulation2021,14,1:6
11Ambient noise spectral properties in the north area of Xisha显示文摘Ambient noise is very important in the prediction system of a sonar performance, because it determines the detection ranges always in a passive sonar and usually in an active sonar. In the uncertainty issue for the sonar performance, it is necessary to know this factor's statistical characteristics that are only obtained by data processing from the underwater ambient noise measurements. Broad-band ambient noise signals from 16 hydrophones were amplified and recorded for 2 min every 1 h. The results show that the ambient noise is essentially depth independent. The cross correlation of the ambient noise levels(1, 6 and 12 h average) with a wind speed is presented. It was found that the correlation is excellent on the upper frequency band and the noise levels correlate better with high wind speed than with low wind speed.DA Lianglong WANG Chao HAN Mei ZHANG Lin 2014Acta Oceanologica Sinica2014,33,12:6
12Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications.Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang 2020Nano Research2020,13,12:6

14Adaptive backtracking search optimization algorithm with pattern search for numerical optimization显示文摘The backtracking search optimization algorithm(BSA) is one of the most recently proposed population-based evolutionary algorithms for global optimization. Due to its memory ability and simple structure, BSA has powerful capability to find global optimal solutions. However, the algorithm is still insufficient in balancing the exploration and the exploitation. Therefore, an improved adaptive backtracking search optimization algorithm combined with modified Hooke-Jeeves pattern search is proposed for numerical global optimization. It has two main parts: the BSA is used for the exploration phase and the modified pattern search method completes the exploitation phase. In particular, a simple but effective strategy of adapting one of BSA's important control parameters is introduced. The proposed algorithm is compared with standard BSA, three state-of-the-art evolutionary algorithms and three superior algorithms in IEEE Congress on Evolutionary Computation 2014(IEEE CEC2014) over six widely-used benchmarks and 22 real-parameter single objective numerical optimization benchmarks in IEEE CEC2014. The results of experiment and statistical analysis demonstrate the effectiveness and efficiency of the proposed algorithm.Shu Wang Xinyu Da Mudong Li Tong Han 2016Journal of Systems Engineering and Electronics2016,27,2:5
15Hwangryunhaedoktang exerts anti-inflammation on LPS-induced NO production by suppressing MAPK and NF-κB activation in RAW264.7 macrophages显示文摘OBJECTIVE: This study aimed to evaluate whether Hwangryunhaedoktang(HHT), a herbal compound, has an inhibitory effect on lipopolysaccharide(LPS)-induced inflammation in RAW264.7 macrophages.METHODS: The effects of HHT were evaluated by confirming nitric oxide(NO) production and expression of inducible NO synthase(iN OS) and mitogen-activated protein kinases(MAPKs) in LPS-stimulated RAW264.7 macrophages via the Griess assay, Western blotting, and real-time reverse transcription quantitative polymerase chain reaction. Western blot analyses and luciferase assays were used to evaluate whether HHT has an effect on the phosphorylation and translocation of nuclear factor-κB(NF-κB). The secretion and expression of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) were determined via enzyme-linked immunosorbent assay and Western blot analyses.RESULTS: HHT suppressed LPS-induced NO production and expression of iN OS in a dose-dependent manner. Additionally, MAPKs activation was also attenuated via inhibition of phosphorylation of extracellular signal-regulated kinases 1/2, c-Jun N-terminal kinase and p38 which were related to inflammatory pathway. Furthermore, HHT also effectively attenuated NF-κB activation and its translocation to the nucleus, a process that is closely linked to inflammation. LPS normally induced the expression of inflammatory cytokines such as TNF-α and IL-6, but the secretion and expression of TNF-α and IL-6 were significantly attenuated by pretreating the cells with HHT.CONCLUSION: HHT suppressed LPS-induced NO production by blocking the activation of NF-κB and MAPK signaling pathways in RAW264.7 macrophages. Furthermore, HHT may have an anti-inflammatory effect by suppressing the LPS-induced secretion of TNF-α and IL-6. Therefore, the traditional herbal formula HHT might be a useful potential therapeutic agent for inflammation.Byung Hyuk Han Yun Jung Lee Jung Joo Yoon Eun Sik Choi Seung Namgung Xian Jun Jin Da Hye Jeong Dae Gill Kang Ho Sub Lee 2017Journal of Integrative Medicine2017,15,4:5

17PCDH17 increases the sensitivity of colorectal cancer to 5-fluorouracil treatment by inducing apoptosis and autophagic cell death显示文摘5-Fluorouracil(5-FU)is known as a first-line chemotherapeutic agent against colorectal cancer(CRC),but drug resistance occurs frequently and significantly limits its clinical success.Our previous study showed that the protocadherin 17(PCDH17)gene was frequently methylated and functioned as a tumor suppressor in CRC.However,the relationship between PCDH17 and 5-FU resistance in CRC remains unclear.Here,we revealed that PCDH17 was more highly expressed in 5-FU-sensitive CRC tissues than in 5-FU-resistant CRC tissues,and high expression of PCDH17 was correlated with high BECN1 expression.Moreover,this expression profile contributed to superior prognosis and increased survival in CRC patients.Restoring PCDH17 expression augmented the 5-FU sensitivity of CRC in vitro and in vivo by promoting apoptosis and autophagic cell death.Furthermore,autophagy played a dominant role in PCDH17-induced cell death,as an autophagy inhibitor blocked cell death to a greater extent than the pancaspase inhibitor Z-VAD-FMK.PCDH17 inhibition by siRNA decreased the autophagy response and 5-FU sensitivity.Mechanistically,we showed that c-Jun NH2-terminal kinase(JNK)activation was a key determinant in PCDH17-induced autophagy.The compound SP600125,an inhibitor of JNK,suppressed autophagy and 5-FU-induced cell death in PCDH17-reexpressing CRC cells.Taken together,our findings suggest for the first time that PCDH17 increases the sensitivity of CRC to 5-FU treatment by inducing apoptosis and JNK-dependent autophagic cell death.PCDH17 may be a potential prognostic marker for predicting 5-FU sensitivity in CRC patients.Shuiping Liu Haoming Lin Da Wang Qiang Li Hong Luo Guoxiong Li Xiaohui Chen Yongqiang Li Peng Chen Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Mingming Zhang Xuemeng Han Qiujie Li Liuxi Chen Ying Liu Xiaying Chen Guohua Li Yu Xiang Ting Duan Jiao Feng Jianshu Lou Xingxing Huang Qin Zhang Ting Pan Lili Yan Ting Jin Wenzheng Zhang Lvjia Zhuo Yitian Sun Tian Xie Xinbing Sui 2019Signal Transduction and Targeted Therapy2019,4,1:4
18Gut-brain axis:Focus on gut metabolites short-chain fatty acids显示文摘Emerging evidence supports that the gut microbiome,reconsidered as a new organ in the human body,can not only affect the local gut,but also communicate with the brain via multiple pathways related to neuroendocrine,immune,and neural pathways,thereby proposing the new concept of the microbiome-gut-brain(MGB)axis.Recently,the role of short-chain fatty acids(SCFAs),which are the main anaerobic fermented metabolites of the gut microbiota in the MGB axis,has garnered significant attention.SCFAs are involved in a broad range of central neurological diseases,including neurodegenerative diseases,cerebral vascular diseases,epilepsy,neuroimmune inflammatory diseases,and mood disorders.However,the underlying mechanism of SCFA-related distant organ crosstalk is yet to be elucidated.Herein,we summarize current knowledge regarding interactions between SCFAs and the MGB axis,as well as their protective effects against central neurological diseases.Cen Guo Ya-Jing Huo Yu Li Yan Han Da Zhou 2022World Journal of Clinical Cases2022,10,6:4

20Involvement of heme oxygenase-1 induction in anti-vascular inflammation effects of Xanthoceras sorbifolia in human umbilical vein endothelial cells显示文摘OBJECTIVE: To define the effects of Xanthoceras sorbifolia(EXS) on vascular inflammation and the mechanisms in endothelial cells.METHODS: Vascular protective effects of an ethanol extract of seeds from EXS(1-50 μg/mL) against tumor necrosis factor-α(TNF-α)-induced vascularinflammation were examined in human umbilical vein endothelial cells(HUVECs).RESULTS: EXS significantly decreased TNF-α-induced expression of cell adhesion molecules, such as intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and endothelial cell selectin,in a dose-dependent manner. Pre-treatment with EXS significantly inhibited translocation and transcriptional activity of nuclear factor-κB(NF-κB) increased by TNF-α. EXS also significantly inhibited formation of intracellular reactive oxygen species(ROS). Moreover, the vascular protective effects of EXS were linked to up-regulation of heme oxygenase-1(HO-1) and nuclear factor E2-related factor-2(Nrf-2) expression. EXS-induced HO-1 expression was significantly decreased in SnPP(HO-1 inhibitor)-and HO-1 siRNA-treated cells, whereas an increase was found in cobalt protoporphyrin IX(CoPP)(HO-1 inducer)-treated cells. In addition, pretreatment with EXS increased HO-1 and Nrf-2 expression under TNF-α stimulation with or without N-acetyl-L-cysteine. Furthermore, the inhibitory effects of EXS on TNF-α-induced vascular inflammation were partially reversed in SnPP-and of HO-1siRNA-treated cells but increased by CoPP.CONCLUSION: These results suggest that EXS may have important implications for prevention of vascular complications associated with vascular inflammation by inhibition of the NF-κB/ROS pathway and activation of the Nrf-2/HO-1 pathway.Jung Joo Yoon Byung Hyuk Han Eun Sik Choi Seung Namgung Da Hye Jeong Song Nan Jin Yun Jung Lee Dae Gill Kang Ho Sub Lee 2018Journal of Traditional Chinese Medicine2018,38,6:4
