| 1 | A study of preoperative methionine-depleting parenteral nutrition plus chemotherapy in gastric cancer patients显示文摘AIM To investigate the interference ofmethionine.free parenteral nutrition plus 5-Fu(-MetTPN+5-Fu)in gastric cancer cell kineticsand the side effects of the regimen.METHODS Fifteen patients with advancedgastric cancer were randomly divided into twogroups,7 patients were given preoperatively aseven-day course of standard parenteralnutrition in combination with a five-day courseof chemotherapy(sTPN+5-Fu),while the other8 patients were given methionine-deprivedparenteral nutrition and 5-Fu(-MetTPN+5-Fu).Cell cycles of gastric cancer and normal mucosawere studied by flow cytometry(FCM).Bloodsamples were taken to measure the serumprotein,methionine(Met)and cysteine(Cys)levels,and liver and kidney functions.RESULTS As compared with the resultsobtained before the treatment,the percentage ofG0/G1 tumor cells increased and that of S phasedecreased in the-MetTPN+5-Fu group,while thecontrary was observed in the sTPN+5-Fu group.Except that the ALT,AST and AKP levels wereslightly increased in a few cases receiving-MetTPN+5-Fu,all the other biochemicalparameters were within normal limits.Serum Cys level decreased slightly after the treatmentin both groups.Serum Met level of patientsreceiving sTPN+5-Fu was somewhat higher aftertreatment than that before treatment;however,no significant change occurred in the -MetTPN+5-Fu group,nor operative complications in bothgroups.CONCLUSION -MetTPN+5-Fu exerted asuppressive effect on cancer cell proliferation,probably through a double mechanism ofcreating a state of'Met starvation'adverse tothe tumor cell cycle,and by allowing 5-Fu to killspecifically cells in S phase.Preoperative short-term administration of -MetTPN+5-Fu had littleundesirable effect on host metabolism. | Cao WX Cheng QM Fei XF Li SF Yin HR Lin YZ | 2000 | World Journal of Gastroenterology2000，6，2： | 22 |

| 8 | Carbide Behavior during High Temperature Creep in DZ40M Co-base Superalloy显示文摘The carbide behavior of a directionalIy solidified Co-base superalloy DZ40M has been investigatedafter creep at 700° and 900°. During the high temperature creep, a great amount of secondary carbide, M3C6 precipitated in alloy matrix. At 700℃, the M23C6 precipitation occurred in slip bands, indicating that it was stress-induced, while at 900℃, M23C6 formed surrounding the primary carbides, which is a characteristic of thermally aged alloy. The M23C6 particles pinned up dislocations and subgrain boundaries, strengthening the alloy matrix effectively. The creep crack initiation of DZ40M alloy was exclusively related to the primary carbides. The fracture of the primary carbide and the crack at the interface between them and matrix resulted in the crack formation. Furthermore, it was found that at 900℃, the surface of specimens was oxidized severely and the preferentially oxidized primary carbides acted as crack initiation sites. | Jiang, WH Yao, XD Guan, HR Hu, ZQ | 1999 | Journal of Materials Science & Technology1999，15，6： | 6 |
| 9 | Prospective evaluation of small bowel preparation with bisacodyl and sodium phosphate for capsule endoscopy显示文摘AIM: To determine the effect of Prepacol?, a com- bination of sodium phosphate and bisacodyl, on transit and quality of capsule endoscopy (CE). METHODS: Fivety two consecutive patients were included in this prospective study. CE was performed following a 12 h fasting period. Twenty six patients were randomized for additional preparation with Prepacol?. The quality of CE was assessed separately for the proximal and the distal small bowel by 3 experienced endoscopists on the basis of a graduation which was initially developed with 20 previous CE. RESULTS: Preparation with Prepacol? accelerated small bowel transit time (262 ± 55 min vs 287 ± 97 min), but had no effect on the quality of CE. Visibility was significantly reduced in the distal compared to the proximal small bowel. CONCLUSION: The significantly reduced visibility of CE in the distal small bowel allocates the need for a good preparation. Since Prepacol? has no beneficial effect on CE the modality of preparation and the ideal time of application remains unclear. Further standardized examinations are necessary to identify sufficient preparation procedures and to determine the impact of the volume of the preparation solution. | Andreas Franke Frank Hummel Phillip Knebel Christoph Antoni Ulrich Bcker Manfred V Singer Matthias Lhr | 2008 | World Journal of Gastroenterology2008，14，13： | 5 |

| 11 | Human small intestine is capable of restoring barrier function after short ischemic periods显示文摘AIM To assess intestinal barrier function during human intestinal ischemia and reperfusion(IR).METHODS In a human experimental model,6 cm of jejunum was selectively exposed to 30 min of ischemia(I) followed by 30 and 120 min of reperfusion(R). A sham procedure was also performed. Blood and tissue was sampled at all-time points. Functional barrier function was assessed using dual-sugar absorption tests with lactulose(L) and rhamnose(R). Plasma concentrations of citrulline,an amino acid described as marker for enterocyte function were measured as marker of metabolic enterocytes restoration. Damage to the epithelial lining was assessed by immunohistochemistry for tight junctions( TJs),by plasma marker for enterocytes damage(I-FABP) and analyzed by electron microscopy(EM) using lanthanum nitrate as an electrondense marker.RESULTS Plasma L/R ratio's were significantly increased after 30 min of ischemia(30 I) followed by 30 min of reperfusion(30 R) compared to control(0.75 ± 0.10 vs 0.20 ± 0.09,P < 0.05). At 120 min of reperfusion(120 R),ratio's normalized(0.17 ± 0.06) and were not significantly different from control. Plasma levels of I-FABP correlated with plasma L/R ratios measured at the same time points(correlation: 0.467,P < 0.01). TJs staining shows distortion of staining at 30 I. An intact lining of TJs was again observed at 30 I120 R. Electron microscopy analysis revealed disrupted TJs after 30 I with paracellular leakage of lanthanum nitrate,which restored after 30 I120 R. Furthermore,citrulline concentrations closely paralleled the histological perturbations during intestinal IR.CONCLUSION This study directly correlates histological data with intestinal permeability tests,revealing that the human gut has the ability of to withstand short episodes of ischemia,with morphological and functional recovery of the intestinal barrier within 120 min of reperfusion. | Dirk HSM Schellekens Inca HR Hundscheid Claire AJI Leenarts Joep Grootjans Kaatje Lenaerts Wim A Buurman Cornelis HC Dejong Joep PM Derikx | 2017 | World Journal of Gastroenterology2017，23，48： | 4 |

| 15 | Spotlights on immunological effects of reactive nitrogen species: When inflammation says nitric oxide显示文摘Over the last decades, nitric oxide(NO) has been definitively recognised as one of the key players involved in immunity and inflammation. NO generation was originally described in activated macrophages, which still represent the prototype of NO-producing cells. Notwithstanding, additional cell subsets belonging to both innate and adaptive immunity have been documented to sustain NO propagation by means of the enzymatic activity of different nitric oxide synthase isoforms. Furthermore, due to its chemical characteristics, NO could rapidly react with other free radicals to generate different reactive nitrogen species(RNS), which have been intriguingly associated with many pathological conditions. Nonetheless, the plethora of NO/RNS-mediated effects still remains extremely puzzling. The aim of this manuscript is to dig into the broad literature on the topic to provide intriguing insights on NO-mediated circuits within immune system. We analysed NO and RNS immunological clues arising from their biochemical properties, immunomodulatory activities and finally dealing with their impact on different pathological scenarios with far prompting intriguing perspectives for their pharmacological targeting. | Andrea Predonzani Bianca Calì Andrielly HR Agnellini Barbara Molon | 2015 | World Journal of Experimental Medicine2015，5，2： | 3 |

| 18 | Appended corrole manganese complexes:Catalysis and axial-ligand effect显示文摘A series of N-base appended corroles and their manganese complexes were synthesized and their binding constants with three different nitrogenous ligands,triethylamine,N-methylimidazole and pyridine,were evaluated by spectroscopy.Kinetic studies indicated that the presence of appended Ndonor ligands may cause a significant enhancement of the rate of oxygen atom transfers(OAT) from(oxo)manganese(V) corrole to alkene,and the stronger axial ligand binding has impact on the rate of the oxidation reaction.Turnover frequency(TOF) for the catalytic oxidation of alkenes by appended manganese corroles varies with the following ligand order:acetamido < pyridyl < imidazolyl.The influence of the external axial ligands on the catalytic epoxidation was investigated by using appended acetamido manganese corrole as catalyst,with the results revealing that N-methylimidazole gave the best enhancement on the yields of total oxidation products among the investigated nitrogenous ligands. | Nga-Chun Ng Mian HR Mahmood Chi-K.Chang Hai-Yang Liu Fei Yam Lam-Lung Yeung | 2014 | Chinese Chemical Letters2014，25，4： | 3 |
