1Geochemical and Pb-Sr-Nd isotopic compositions of Indosinian granitoids from the Bikou block,northwest of the Yangtze plate:Constraints on petrogenesis,nature of deep crust and geodynamics显示文摘This paper reports geochemical and Pb-Sr-Nd isotopic compositions of the Indosinian Yangba (215 Ma),Nanyili (225 Ma) and Mopi granitoids from the Bikou block of the northwestern margin of the Yangtze plate. These granitoids are enriched in Al (Al2O3:14.56%―16.48%) and Sr (352 μg/g―1047 μg/g),and depleted in Y (<16 μg/g) and HREE (e.g. Yb<1.61 μg/g),resulting in high Sr/Y (36.3―150) and (La/Yb)N (7.8―36.3) ratios and strongly fractionationed REE patterns. The Indosinian granotoids show initial Sr isotopic ratios (ISr) from 0.70419 to 70752,εNd(t) values from-3.1 to -8.5,and initial Pb isotopic ratios 206Pb/204Pb=17.891-18.250,207Pb/204Pb=15.494-15.575,and 208Pb/204Pb=37.788-38.335. Their geochemi-cal signatures indicate that the granitoids are adakitic. However,they are distinct from some adakites,generated by partial melting of subducted oceanic slab and/or underplated basaltic lower crust,be-cause they have high K (K2O: 1.49%―3.84%) and evolved Nd isotopic compositions,with older Nd iso-topic model ages (TDM=1.06―1.83 Ga). Geochemical and Sr-Nd isotopic compositions suggest that the magmas of the Insoninian adakitic rocks in the Bikou block were derived from partial melting of thick-ened basaltic lower crust. Combined with regional analyses,a lithospheric delamination model after collision between the North China and South China plates can account for the Indosinian adakitic magma generation. On the other hand,based on the Pb-Sr-Nd isotopic probing to the magma sources of the adakitic rocks,it is suggested that there is an unexposed continent-type basement under the exposed Bikou Group volcanic rocks. This can constrain on the Bikou Group volcanic rocks not to be MORB-or OIB-type.ZHANG HongFei XIAO Long ZHANG Li YUAN HongLin JIN LanLan 2007Science China Earth Sciences2007,50,7:38

5Nuclear factor-kappaB activation on the reactive oxygen species in acute necrotizing pancreatitic rats显示文摘AIM: To investigate the potential role of nuclear factor kappa-B (NF-κB) activation on the reactive oxygen species in rat acute necrotizing pancreatitis (ANP) and to assess the effect of pyrrolidine dithiocarbamate (PDTC, an inhibitor of NF-κB).METHODS: Rat ANP model was established by retrograde injection of 5% sodium taurocholate into biliopancreatic duct. Rats were randomly assigned to three groups (10rats each): Control group, ANP group and PDTC group. At the 6th h of the model, the changes of the serum amylase,nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD) and pancreatic morphological damage were observed. The expressions of inducible nitric oxide (iNOS) were observed by SP immunohistochemistry. And the expressions of NF-κB p65 subunit mRNA were observed by hybridization in situ.RESULTS: Serum amylase and NO level decreased significantly in ANP group as compared with PDTC administrated group [(7 170.40±1 308.63) U/L vs(4 074.10±1 719.78) U/L,P<0.05], [(76.95±9.04) μmol/L vs (65.18±9.02) μmol/L,P<0.05] respectively. MDA in both ANP and PDTC group rose significantly over that in control group [(9.88±1.52)nmol/L, (8.60±1.41) nmol/L, vs (6.04±1.78) nmol/L,P<0.05], while there was no significant difference between them. SOD levels in both ANP and PDTC group underwent a significant decrease as compared with that in control [(3 214.59±297.74) NU/mL, (3 260.62±229.44) NU/mL,vs (3 977.80±309.09) NU/mL, P<0.05], but there was no significant difference between them. Though they were still higher than those in Control group, pancreas destruction was slighter in PDTC group, iNOS expression and NF-κB p65 subunit mRNA expression were lower in PDTC group as compared with ANP group.CONCLUSION: We conclude that correlation among NF-κB activation, serum amylase, reactive oxygen species level and tissue damage suggests a key role of NF-κB in the pathogenesis of ANP. Inhibition of NF-κB activation may reverse the pancreatic damage of rat ANP and the production of reactive oxygen species.Jin Long Na Song Xi-Ping Liu Ke-Jian Guo Ren-Xuan Guo 2005World Journal of Gastroenterology2005,11,27:18
6Expediting redox kinetics of sulfur species by atomic-scale electrocatalysts in lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)batteries have extremely high theoretical energy density that make them as promising systems toward vast practical applications.Expediting redox kinetics of sulfur species is a decisive task to break the kinetic limitation of insulating lithium sulfide/disulfide precipitation/dissolution.Herein,we proposed a porphyrinderived atomic electrocatalyst to exert atomic-efficient electrocatalytic effects on polysulfide intermediates.Quantifying electrocatalytic efficiency of liquid/solid conversion through a potentiostatic intermittent titration technique measurement presents a kinetic understanding of specific phase evolutions imparted by the atomic electrocatalyst.Benefiting from atomically dispersed“lithiophilic”and“sulfiphilic”sites on conductive substrates,the finely designed atomic electrocatalyst endows Li–S cells with remarkable cycling stablity(cyclic decay rate of 0.10%in 300 cycles),excellent rate capability(1035 mAh g−1 at 2 C),and impressive areal capacity(10.9 mAh cm−2 at a sulfur loading of 11.3 mg cm−2).The present work expands atomic electrocatalysts to the Li–S chemistry,deepens kinetic understanding of sulfur species evolution,and encourages application of emerging electrocatalysis in other multielectron/multiphase reaction energy systems.Bo-Quan Li Long Kong Chang-Xin Zhao Qi Jin Xiao Chen Hong-Jie Peng Jin-Lei Qin Jin-Xiu Chen Hong Yuan Qiang Zhang Jia-Qi Huang 2019InfoMat2019,1,4:18

9Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases.Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao 2021Hepatobiliary Surgery and Nutrition2021,10,4:17
10Prognostic factors and survival in patients with gastric stump cancer显示文摘AIM:To elucidate the clinicopathological characteristics and prognostic factors of gastric stump cancer(GSC).METHODS:The clinical data for 92 patients with GSC were collected at Fudan University Shanghai Cancer Center.The prognostic factors were analyzed with Cox proportional hazard models.RESULTS:GSC tended to occur within 25 years following the primary surgery,when the initial disease is benign,whereas it primarily occurred within the first15 years post-operation for gastric cancer.Patients with regular follow-up after primary surgery had a better survival rate.The multivariate Cox regression analysis revealed that Borrmann type?Ⅰ/Ⅱ(HR=3.165,95%CI:1.055-9.500,P=0.040)and radical resection(HR=1.780,95%CI:1.061-2.987,P=0.029)were independent prognostic factors for GSC.The overall 1-,3-,and 5-year survival rates of the 92 patients were78.3%,45.6%and 27.6%,respectively.The 1-,3-,and 5-year survival rates of those undergoing radical resection were 79.3%,52.2%,and 37.8%,respectively.The 5-year survival rates for stages?Ⅰ,Ⅱ,Ⅲ,andⅣwere 85.7%,47.4%,16.0%,and 13.3%,respectively(P=0.005).CONCLUSION:The appearance of GSC occurs sooner in patients with primary malignant cancer than in patients with a primary benign disease.Therefore,close follow-up is necessary.The overall survival of patients with GSC is poor,and curative resection can improve their prognosis.Hua Huang Wei Wang Zhong Chen Jie-Jie Jin Zi-Wen Long Hong Cai Xiao-Wen Liu Ye Zhou Ya-Nong Wang 2015World Journal of Gastroenterology2015,21,6:16
11Long noncoding RNA RP4 functions as a competing endogenous RNA through miR-7-5p sponge activity in colorectal cancer显示文摘AIM To investigate the role of long noncoding RNA(lnc RNA) RP4 in colorectal cancer.METHODS Lentivirus-mediated lnc RNA RP4 overexpression and knockdown were performed in the colorectal cancer cell line SW480. Cell proliferation, tumor growth, and early apoptosis were evaluated by a cell counting kit-8 assay, an in vivo xenograft tumor model, and annexin V/propidium iodide staining, respectively. Analysis of the lnc RNA RP4 mechanism involved assessment of the association of its expression with mi R-7-5 p and the SH3 GLB1 gene. Western blot analysis was also performed to assess the effect of lnc RNA RP4 on the autophagy-mediated cell death pathway and phosphatidylinositol-3-kinase(PI3 K)/Akt signaling.RESULTS Cell proliferation, tumor growth, and early apoptosis in SW480 cells were negatively regulated by lnc RNA RP4. Functional experiments indicated that lnc RNA RP4 directly upregulated SH3 GLB1 expression by acting as a competing endogenous RNA(ce RNA) for mi R-7-5 p. This interaction led to activation of the autophagy-mediated cell death pathway and de-repression of PI3 K and Akt phosphorylation in colorectal cancer cells in vivo.CONCLUSION Our results demonstrated that lnc RNA RP4 is a ce RNA that plays an important role in the pathogenesis of colorectal cancer, and could be a potential therapeutic target for colorectal cancer treatment.Mu-Lin Liu Qiao Zhang Xiao Yuan Long Jin Li-Li Wang Tao-Tao Fang Wen-Bin Wang 2018World Journal of Gastroenterology2018,24,9:16
12Adult intussusception:A retrospective review of 41 cases显示文摘AIM:To optimize the preoperative diagnosis and surgical management of adult intussusception (AI).METHODS:A retrospective review of the clinical features,diagnosis,management and pathology 41 adult patients with postoperative diagnoses of intussusception was conducted.RESULTS:Forty-one patients with 44 intussusceptions were operated on,24.4% had acute symptoms,24.4% had subacute symptoms,and 51.2% had chronic symptoms.70.7% of the patients presented with intestinal obstruction.There were 20 enteric,15 ileocolic,eight colocolonic and one sigmoidorectal intussusceptions.65.9% of intussusceptions were diagnosed preoperatively using a computed tomography (CT) scan (90.5% accurate) and ultrasonography (60.0% accurate,rising to 91.7% for patients who had a palpable abdominal mass).Coloscopy located the occupying lesions of the lead point of ileocolic,colocolonic and sigmoidorectal intussusceptions.Four intussusceptions in three patients were simply reduced.Twenty-one patients underwent resection after primary reduction.There was no mortality and anastomosis leakage perioperatively.Except for one patient with multiple small bowel adenomas,which recurred 5 mo after surgery,no patients were recurrent within 6 mo.Pathologically,54.5% of the intussusceptions had a tumor,of which 27.3% were malignant.9.1% comprised nontumorous polyps.Four intussusceptions had a gastrojejunostomy with intestinal intubation,and four intussusceptions had no organic lesion.CONCLUSION:CT is the most effective and accurate diagnostic technique.Colonoscopy can detect most lead point lesions of non-enteric intussusceptions.Intestinal intubation should be avoided.Ning Wang Xing-Yu Cui Yu Liu Jin Long Yuan-Hong Xu Ren-Xuan Guo Ke-Jian Guo 2009World Journal of Gastroenterology2009,15,26:15

14Towards full demonstration of high areal loading sulfur cathode in lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)batteries have been recognized as promising substitutes for current energy-storage technologies owing to their exceptional advantages in very high-energy density and excellent material sustainability.The cathode with high sulfur areal loading is vital for the practical applications of Li–S batteries with very high energy density.However,the high sulfur loading in an electrode results in poor rate and cycling performances of batteries in most cases.Herein,we used diameters of 5.0(D5)and 13.0(D13)mm to probe the effect of electrodes with different sizes on the rate and cycling performances under a high sulfur loading(4.5 mg cm^-2).The cell with D5 sulfur cathode exhibits better rate and cycling performances comparing with a large(D13)cathode.Both the high concentration of lithium polysulfides and corrosion of lithium metal anode impede rapid kinetics of sulfur redox reactions,which results in inferior battery performance of the Li–S cell with large diameter cathode.This work highlights the importance of rational matching of the large sulfur cathode with a high areal sulfur loading,carbon modified separators,organic electrolyte,and Li metal anode in a pouch cell,wherein the sulfur redox kinetics and lithium metal protection should be carefully considered under the flooded lithium polysulfide conditions in a working Li–S battery.Long Kong Qi Jin Xi-Tian Zhang Bo-Quan Li Jin-Xiu Chen Wan-Cheng Zhu Jia-Qi Huang Qiang Zhang 2019Journal of Energy Chemistry2019,28,12:13
15Primary intestinal malignant fibrous histiocytoma:two case reports显示文摘Malignant fibrous histiocytoma (MFH) occurs most commonly in the extremities and trunk, but rarely in the intestine. Here we report two cases of primary intestinal MFH. The first case was a 70-year old man admitted for recurrent right lower quadrant abdominal pain. At laparotomy, a tumor was found originating from the cecum, with a suspicious metastatic nodule on the surface of the right lobe of the liver. A right hemicolectomy was performed followed by an ileotransverse end-to-end anastomotic reconstruction. The second case was a 43-year old man with intussusceptions of the small intestine. An emergent laparotomy revealed 4 pedunculated masses in the small bowel and a partial resection of the small intestine was performed. Though the symptoms were not typical, based on histological and immunohistochemical studies, the patients were diagnosed as MFH of the intestine. They were not treated with chemotherapy or radiotherapy and both died within 3 mo. MFH of the intestine is an extremely rare neoplasm with an aggressive biological behavior. The pathogenesis of this disease has not been clarified to date. Complete surgical excision is preferred, adjuvant chemotherapy or radiotherapy may be advisable.De-Liang Fu Feng Yang Ashish Maskay Jiang Long Chen Jin Xian-Jun Yu Jin Xu Zhong-Wen Zhou Quan-Xing Ni 2007World Journal of Gastroenterology2007,13,8:13

19Seasonal and inter-annual variations in carbon fluxes and evapotranspiration over cotton field under drip irrigation with plastic mulch in an arid region of Northwest China显示文摘Xinjiang is the largest semi-arid and arid region in China, and drip irrigation under plastic mulch is widely used in this water-limited area. Quantifying carbon and water fluxes as well as investigating their environmental drivers over cotton fields is critical for understanding regional carbon and water budgets in Xinjiang, the largest cotton production basin of China. In this study, an eddy covariance(EC) technique was used to measure the carbon and water fluxes of cotton field under drip irrigation with plastic mulch in the growing seasons of 2009, 2010, 2012 and 2013 at Wulanwusu Agrometeorological Experiment Station, a representative oasis cropland in northern Xinjiang. The diurnal patterns of gross primary production(GPP), net ecosystem exchange(NEE) and evapotranspiration(ET) showed obviously sinusoidal variations from June to September, while the diurnal ecosystem respiration(Res) was stable between daytime and nighttime. The daytime hourly GPP and ET displayed asymptotic relationships with net solar radiation(Rnet), while showed concave patterns with raising vapor pressure deficit(VPD) and air temperature(Ta). The increases in hourly GPP and ET towards the maximum occurred over half ranges of VPD and Ta. The seasonal variations of GPP, NEE and ET were close to the cotton phenology, which almost reached the peak value in July. The cumulative GPP averaged 816.2±55.0 g C/m2 in the growing season(from April to October), and more than half of GPP was partitioned into NEE(mean value of –478.6±41.4 g C/m2). The mean seasonal ET was 501.3±13.9 mm, and the mean water use efficiency(WUE) was 1.0±0.1(mg C/g H2O)/d. The agro-ecosystem behaved as a carbon sink from squaring to harvest period, while it acted as a carbon source before the squaring time as well as after the harvest time.Jie BAI Jin WANG Xi CHEN Ge Ping LUO Hao SHI Long Hui LI Jun Li LI 2015Journal of Arid Land2015,7,2:12
