3Chemotherapy with laparoscope-assisted continuous circulatory hyperthermic intraperitoneal perfusion for malignant ascites显示文摘AIM:To investigate the procedure, feasibility and effects of laparoscopeassisted continuous circulatory hyperthermic intraperitoneal perfusion chemotherapy (CHIPC) in treatment of malignant ascites induced by peritoneal carcinomatosis from gastric cancers. METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscopeassisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5 fluorouracil (5FU) and 200 mg oxaliplatin were added in the perfusion solution. The second andthird sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450600 mL/min and an in flow temperature of 43 ± 0.2℃.RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscopeassisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscopeassisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the followup, 13 patients died 29 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (5090) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscopeassisted CHIPC is a safe, feasible and effective procedure in the treatment of debilitating malignant ascites induced by unresectable gastric cancers.Ba, Ming-Chen Cui, Shu-Zhong Lin, Sheng-Qu Tang, Yun-Qiang Wu, Yin-Bing Wang, Bin Zhang, Xiang-Liang 2010World Journal of Gastroenterology2010,16,15:50
4Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29
5African Swine Fever Virus MGF360-12L Inhibits Type Ⅰ Interferon Production by Blocking the Interaction of Importin α and NF-κB Signaling Pathway显示文摘African swine fever(ASF)is an infectious transboundary disease of domestic pigs and wild boar and spreading throughout Eurasia.There is no vaccine and treatment available.Complex immune escape strategies of African swine fever virus(ASFV)are crucial factors affecting immune prevention and vaccine development.MGF360 genes have been implicated in the modulation of the IFN-Ⅰresponse.The molecular mechanisms contributing to innate immunity are poorly understood.In this study,we demonstrated that ASFV MGF360-12 L(MGF360 families 12 L protein)significantly inhibited the mRNA transcription and promoter activity of IFN-βand NF-κB,accompanied by decreases of IRF3,STING,TBK1,ISG54,ISG56 and AP-1 m RNA transcription.Also,MGF360-12 L might suppress the nuclear localization of p50 and p65 mediated by classical nuclear localization signal(NLS).Additionally,MGF360-12 L could interact with KPNA2,KPNA3,and KPNA4,which interrupted the interaction between p65 and KPNA2,KPNA3,KPNA4.We further found that MGF360-12 L could interfere with the NF-κB nuclear translocation by competitively inhibiting the interaction between NF-κB and nuclear transport proteins.These findings suggested that MGF360-12 L could inhibit the IFN-Ⅰproduction by blocking the interaction of importinαand NF-κB signaling pathway,which might reveal a novel strategy for ASFV to escape the host innate immune response.Yisha Zhuo Zeheng Guo Tongtong Ba Cheng Zhang Lihua He Cuiping Zeng Hanchuan Dai 2021Virologica Sinica2021,36,2:21
6Diamonds and Other Exotic Minerals Recovered from Peridotites of the Dangqiong Ophiolite, Western Yarlung-Zangbo Suture Zone, Tibet显示文摘Various combinations of diamond, moissanite, zircon, quartz, corundum, rutile, titanite, almandine garnet, kyanite, and andalusite have been recovered from the Dangqiong peridotites. More than 80 grains of diamond have been recovered, most of which are pale yellow to reddish-orange to colorless. The grains are all 100-200 μm in size and mostly anhedral, but with a range of morphologies including elongated, octahedral and subhedral varieties. Their identification was confirmed by a characteristic shift in the Raman spectra between 1325 cm^(-1) and 1333 cm^(-1), mostly at 1331.51 cm^(-1) or 1326.96 cm^(-1). Integration of the mineralogical, petrological and geochemical data for the Dongqiong peridotites suggests a multi-stage formation for this body and similar ophiolites in the Yarlung-Zangbo suture zone. Chromian spinel grains and perhaps small bodies of chromitite crystallized at various depths in the upper mantle, and encapsulated the UHP, highly reduced and crustal minerals. Some oceanic crustal slabs containing the chromian spinel and their inclusion were later trapped in suprasubduction zones(SSZ), where they were modified by island arc tholeiitic and boninitic magmas, thus changing the chromian spinel compositions and depositing chromitite ores in melt channels.XIONG Fahui YANG Jingsui ROBINSON Paul T.

8Prediction of Primary Climate Variability Modes at the Beijing Climate Center显示文摘Climate variability modes, usually known as primary climate phenomena, are well recognized as the most important predictability sources in subseasonal–interannual climate prediction. This paper begins by reviewing the research and development carried out, and the recent progress made, at the Beijing Climate Center(BCC) in predicting some primary climate variability modes. These include the El Ni?o–Southern Oscillation(ENSO), Madden–Julian Oscillation(MJO), and Arctic Oscillation(AO), on global scales, as well as the sea surface temperature(SST) modes in the Indian Ocean and North Atlantic, western Pacific subtropical high(WPSH), and the East Asian winter and summer monsoons(EAWM and EASM, respectively), on regional scales. Based on its latest climate and statistical models, the BCC has established a climate phenomenon prediction system(CPPS) and completed a hindcast experiment for the period 1991–2014. The performance of the CPPS in predicting such climate variability modes is systematically evaluated. The results show that skillful predictions have been made for ENSO, MJO, the Indian Ocean basin mode, the WPSH, and partly for the EASM, whereas less skillful predictions were made for the Indian Ocean Dipole(IOD) and North Atlantic SST Tripole, and no clear skill at all for the AO, subtropical IOD, and EAWM. Improvements in the prediction of these climate variability modes with low skill need to be achieved by improving the BCC's climate models, developing physically based statistical models as well as correction methods for model predictions.Some of the monitoring/prediction products of the BCC-CPPS are also introduced in this paper.Hong-Li REN Fei-Fei JIN Lianchun SONG Bo LU Ben TIAN Jinqing ZUO Ying LIU Jie WU Chongbo ZHAO Yu NIE Peiqun ZHANG Jin BA Yujie WU Jianghua WAN Yuping YAN Fang ZHOU 2017Journal of Meteorological Research2017,31,1:13

10Single-shot BOTDA based on an optical chirp chain probe wave for distributed ultrafast measurement显示文摘Brillouin optical time-domain analysis(BOTDA)requires frequency mapping of the Brillouin spectrum to obtain environmental information(e.g.,temperature or strain)over the length of the sensing fiber,with the finite frequencysweeping time-limiting applications to only static or slowly varying strain or temperature environments.To solve this problem,we propose the use of an optical chirp chain probe wave to remove the requirement of frequency sweeping for the Brillouin spectrum,which enables distributed ultrafast strain measurement with a single pump pulse.The optical chirp chain is generated using a frequency-agile technique via a fast-frequency-changing microwave,which covers a larger frequency range around the Stokes frequency relative to the pump wave,so that a distributed Brillouin gain spectrum along the fiber is realized.Dynamic strain measurements for periodic mechanical vibration,mechanical shock,and a switch event are demonstrated at sampling rates of 25 kHz,2.5 MHz and 6.25 MHz,respectively.To the best of our knowledge,this is the first demonstration of distributed Brillouin strain sensing with a wide-dynamic range at a sampling rate of up to the MHz level.Dengwang Zhou Yongkang Dong Benzhang Wang Chao Pang Dexin Ba Hongying Zhang Zhiwei Lu Hui Li Xiaoyi Bao 2018Light(Science & Applications)2018,7,1:11

12Involvement of the Mitochondrion-dependent and the Endoplasmic Reticulum Stress-signaling Pathways in Isoliquiritigenin-induced Apoptosis of HeLa Cell显示文摘Objective Isoliquiritigenin(ISL),a licorice chalconoid,is considered to be a bioactive agent with chemopreventive potential.This study investigates the mechanisms involved in ISL-induced apoptosis in human cervical carcinoma HeLa cells.Methods Cell viability was evaluated using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide(MTT)assay.Apoptosis was determined by flow cytometry using an Annexin V-FITC Apoptosis Detection Kit.The intracellular ROS levels were assessed using a 2,7-dichlorofluorescein probe assay.The mitochondrial membrane potential was measured with the dual-emission potential-sensitive probe 5,5',6,6'-tetra-chloro-1,1',3,3'-tetraethyl-imidacarbocyanine iodide(JC-1).The degradation of poly-ADP-ribose polymerase(PARP)protein,the phosphorylation of PKR-like ER kinase(PERK),the phosphorylation of the α-subunit of eukaryotic initiation factor 2(eIF2α),the expression of the 78 kD glucose-regulated protein(GRP 78),and the activation of caspase-12 were analyzed via western blot analysis.Results ISL significantly inhibited the proliferation,the increase in ROS levels and apoptotic rates of HeLa cells in a concentration-dependent manner.Moreover,ISL induced mitochondrial dysfunction,caspase activation,and PARP cleavage,which displayed features of mitochondria dependent on apoptotic signals.Besides,exposure of HeLa cells to ISL triggered endoplasmic reticulum(ER)stress,as indicated by the increase in p-eIF2α and GRP78 expression,ER stress-dependent apoptosis is caused by the activation of ER-specific caspase-12.Conclusion The findings from our study suggest that ISL-induced oxidative stress causes HeLa cell apoptosis via the mitochondrion-dependent and the ER stress-triggered signaling pathways.YUAN Xuan ZHANG Bo GAN Lu WANG Zhen Hua YU Ba Cui LIU Liang Liang ZHENG Qiu Sheng WANGZhi Ping 2013Biomedical and Environmental Sciences2013,26,4:8
13Irinotecan plus S-1 versus S-1 in patients with previously treated recurrent or metastatic esophageal cancer(ESWN 01):a prospective randomized,multicenter,open-labeled phase 3 trial显示文摘Background:The benefit of systemic treatments in esophageal squamous cell carcinoma(ESCC)which has pro-gressed after chemotherapy is still uncertain and optimal regimens based on randomized trials have not yet been established.We aimed to compare the efficacy of irinotecan plus S-1 with S-1 monotherapy in recurrent or metastatic ESCC patients who had resistance to platinum-or taxane-based chemotherapy.Methods:We conducted a prospective randomized,multicenter,open-label,phase 3 trial in 15 centers across China.Eligible patients were adults with histologically confirmed recurrent or metastatic ESCC,and were randomly assigned(ratio,1:1)to receive either irinotecan plus S-1(intravenous infusion of irinotecan[160 mg/m2]on day 1 and oral S-1[80-120 mg]on days 1-10,repeated every 14 days)or oral S-1 monotherapy(80-120 mg/day on days 1-14,repeated every 21 days)using a central computerized minimization procedure.The primary endpoint was progression-free survival(PFS).Results:Between December 23,2014 and July 25,2016,we screened 148 patients and randomly assigned 123 patients to receive either irinotecan plus S-1 regimen(n=61)or S-1 monotherapy(n=62).After a median follow-up of 29.2 months(95%confidence interval[CI]17.5-40.9 months),the median PFS was significantly longer in the irinotecan plus S-1 group than in the S-1 monotherapy group(3.8 months[95%CI 2.9-4.3 months]vs.1.7 months[95%CI 1.4-2.7 months],hazard ratio=0.58,95%CI 0.38-0.86,P=0.006).The objective response rates were 24.6%in the irinotecan plus S-1 group and 9.7%in the S-1 monotherapy group(P=0.002).The patients in the irinotecan plus S-1 group presented with increased rates of grade 3-4 leukopenia(16.4%vs.0%),neutropenia(14.8%vs.1.6%),and nausea(4.9%vs.0%).No significant difference in grade 3-4 diarrhea and no treatment-related deaths were observed in both groups.Conclusions: The combination of irinotecan with S-1 was similarly tolerable but significantly prolonged PFS compared to S-1 monotherapy as a second- or third-line treatment in patients with recurrent or metastatic ESCC.Jing Huang Binghe Xu Ying Liu Junxing Huang Ping Lu Yi Ba Lin Wu Yuxian Bai Shu Zhang Jifeng Feng Ying Cheng Jie Li Lu Wen Xianglin Yuan Changwu Ma Chunhong Hu Qingxia Fan Xi Wang 2019Cancer Communications2019,39,1:8
14Expert consensus on maintenance treatment for metastatic colorectal cancer in China显示文摘The impact of maintenance therapy on progression-free survival and overall survival as well as quality of life of Chinese patients with metastatic colorectal cancer has long been under discussion.Recently,some phase III clinical trials have revealed that maintenance therapy can significantly prolong the progression-free survival while maintain an acceptable safety profile.Based on this evidence and common treatment practice in China,we now generated one Expert Consensus on Maintenance Treatment for Metastatic Colorectal Cancer in China to further specify the necessity of maintenance therapy,suitable candidates for such treatment,and appropriate regimens.Rui-Hua Xu Lin Shen Jin Li Jian-Ming Xu Feng Bi Yi Ba Li Bai Yong-Qian Shu Tian-Shu Liu Yu-Hong Li Chun-Mei Bai Xiang-Lin Yuan Jun Zhang Gong Chen Ai-Ping Zhou Ying Yuan Xi-Jing Wang Xiao-Ping Qian Yan-Hong Deng 2016Chinese Journal of Cancer2016,35,1:8

18Zircon and Monazite Ages Constraints on Devonian Magmatism and Granulite-Facies Metamorphism in the Southern Qaidam Block:Implications for Evolution of Proto-and Paleo-Tethys in East Asia显示文摘High-temperature magma generation process and granulite-facies metamorphism can provide important information about mantle-crustal interaction and tectonic evolution. The strongly peraluminous monzonite pluton, the Jinshuikou cordierite granite on the southern margin of the Qaidam Block, can provide important information about the mantle-crustal interaction and constraints on tectonic transition from Proto-Tethys to Paleo-Tethys. This pluton develops enclaves of mafic granulite, amphibolite and quartzofeldspathic rocks, and is cut by massive monzonitic leuco-granite veins. Zircon and monazite U-Pb dating for the cordierite granite, the granulite enclaves and a massive monzonitic leuco-granite vein reveal that the cordierite granitic magma was generated from Mesoproterozoic continental crust with protolith derived from a provenance that was composed of >2.8 Ga old recycled crustal materials and recorded a ~1.7 Ga magmatic event. The continental crust underwent low-pressure granulite-facies metamorphism at ~380 Ma ago, whereas the cordierite granite magmas was generated and emplaced during 380 Ma, followed by intrusion of the massive monzonitic leuco-granite vein at circa 370–330 Ma. These data suggest that after the final closure of Proto-Tethys Ocean spreading along the southern Qaidam Block at ~420 Ma, break-off of the subducted slab or delamination of the lower crustal base and upwelling of the asthenospheric mantle beneath the southern Qaidam Block occurred before the Mid-Devonian, and that the initiation of the Paleo-Tethys tectonics might initiate near the end of Early-Carboniferous in the East Kunlun-Qaidam region, East Asia.Jin Ba Lu Zhang Chuan He Neng-Song Chen Timothy M.Kusky Qinyan Wang Yusheng Wan Xiaoming Liu 2018Journal of Earth Science2018,29,5:6

20Diffraction of SH-waves by topographic features in a layered transversely isotropic half-space显示文摘The scattering of plane SH-waves by topographic features in a layered transversely isotropic(TI) half-space is investigated by using an indirect boundary element method(IBEM).Firstly, the anti-plane dynamic stiffness matrix of the layered TI half-space is established and the free fields are solved by using the direct stiffness method.Then, Green's functions are derived for uniformly distributed loads acting on an inclined line in a layered TI half-space and the scattered fields are constructed with the deduced Green's functions.Finally, the free fields are added to the scattered ones to obtain the global dynamic responses.The method is verified by comparing results with the published isotropic ones.Both the steady-state and transient dynamic responses are evaluated and discussed.Numerical results in the frequency domain show that surface motions for the TI media can be significantly different from those for the isotropic case, which are strongly dependent on the anisotropy property, incident angle and incident frequency.Results in the time domain show that the material anisotropy has important effects on the maximum duration and maximum amplitudes of the time histories.Ba Zhenning Liang Jianwen Zhang Yanju 2017Earthquake Engineering and Engineering Vibration2017,16,1:5
