142,573 cases of hepatectomy in China: a multicenter retrospective investigation显示文摘Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival.Binhao Zhang Bixiang Zhang Zhiwei Zhang Zhiyong Huang Yifa Chen Minshan Chen Ping Bie Baogang Peng Liqun Wu Zhiming Wang Bo Li Jia Fan Lunxiu Qin Ping Chen Jingfeng Liu Zhe Tang Jun Niu Xinmin Yin Deyu Li Songqing He Bin Jiang Yilei Mao Weiping Zhou Xiaoping Chen 2018Science China(Life Sciences)2018,61,6:39

5A cellular response protein induced during HSV-1 infection inhibits viral replication by interacting with ATF5显示文摘Studies of herpes simplex virus type 1(HSV-1)infection have shown that many known and unknown cellular molecules involved in viral proliferation are up-regulated following HSV-1 infection.In this study,using two-dimensional polyacrylamide gel electrophoresis,we found that the expression of the HSV-1 infection response repressive protein(HIRRP,GI 16552881)was up-regulated in human L02 cells infected with HSV-1.HIRRP,an unknown protein,was initially localized in the cytoplasm and then translocated into the nucleus of HSV-1-infected cells.Further analysis showed that HIRRP represses HSV-1proliferation by inhibiting transcription of the viral genome by interacting with the cellular transcription factor,ATF5,via its N-terminal domain.ATF5 represses the transcription of many host genes but can also act as an activator of genes containing a specific motif.We found that ATF5 promotes the proliferation of HSV-1 via a potential mechanism by which ATF5 enhances the transcription of viral genes during the course of an HSV-1 infection;HIRRP then induces feedback repression of this transcription by interacting with ATF5.WU LianQiu ZHANG XueMei CHE YanChun ZHANG Ying TANG SongQing LIAO Yun NA RuiXiong XIONG XiangLin LIU LongDing LI QiHan 2013Science China(Life Sciences)2013,56,12:2

13Experiments on the influences of well pattern on water flooding characteristics of dissolution vug-cave reservoir显示文摘Based on the similarity criterion, volcanic rock samples were taken from outcrops to make experimental models. Water flooding experiments of five-spot well pattern, nine-spot well pattern, five-spot to nine-spot well pattern, the relationship between relative well and fracture positions, and injection rate in dissolution vug-cave reservoirs with/without fractures were carried out to analyze variation regularities of development indexes, find out development characteristics of water flooding with different well patterns and sort out the optimal water flooding development mode. For dissolution vug-cave reservoirs without fractures, five-spot well pattern waterflooding has very small sweeping area, serious water channeling and low oil recovery. When the well pattern was adjusted from five-spot to nine-spot well pattern, oil recovery could be largely improved, but the corner well far from the injector is little affected. In dissolution vug-cave reservoirs with fractures, when the injector and producer are not connected by fractures, the fractures could effectively connect the poorly linked vugs to improve the development effect of water flooding. Whether there are fractures or not in dissolution vug-cave reservoirs, the development effect of nine-spot well-pattern is much better than that of five-spot well pattern and five-spot to nine-spot well pattern, this is more evident when there are fractures, and the edge well has better development indexes than corner well. At the high-water cut stage of water flooding with nine-spot well pattern, the oil recovery can be further improved with staggered line-drive pattern by converting the corner well into injection well. It is helpful to increase the oil production of corner well of nine-spot well pattern by increasing the injection rate, and improve ultimate oil recovery, but the water-free production period would be greatly shortened and water-free recovery would decrease.WANG Jing LIU Huiqing ZHANG Jing ZHAO Wei HUANG Yitao KANG Zhijiang ZHENG Songqing 2018Petroleum Exploration and Development2018,45,6:0
14Modeling and analysis of actively Q-switched Fe:ZnSe laser pumped by a 2.8μm fiber laser显示文摘A theoretical model concerning active Q-switching of an Fe:ZnSe laser pumped by a continuous-wave(CW)2.8μm fiber laser is developed.Calculations are compared with the recently reported experiment results,and good agreement is achieved.Effects of principal parameters,including pump power,output reflectivity,ion concentration and temperature of crystal,on the laser output performance are investigated and analyzed.Numerical results demonstrate that similar to highly efficient CWFe:ZnSe laser,low temperature of the crystal is significant to obtain high peak power Q-switched pulses.The numerical simulation results are useful for optimizing the design of actively Q-switched Fe:ZnSe laser.LIANG Xiaolin ZHOU Songqing LIU Zhizhuang BAO Bengang 2023Optoelectronics Letters2023,19,9:0
15BRD7 plays an anti-inflammatory role during early acute inflammation by inhibiting activation of the NF-кB signaling pathway显示文摘Increasing evidence has shown a strong association between tumor-suppressor genes and inflammation.However,the role of BRD7 as a novel tumor suppressor in inflammation remains unknown.In this study,by observing BRD7 knockout mice for 6–12 months,we discovered that compared with BRD7+/+mice,BRD7^(−/−)mice were more prone to inflammation,such as external inflammation and abdominal abscess.By using mouse embryo fibroblast(MEF)cells from the BRD7 knockout mouse,an in vitro lipopolysaccharide(LPS)-stimulated MEF cell line was established.The mRNA levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),chemokine(C-X-C motif)ligand 1(CXCL-1)and inducible nitric oxide synthase(iNOS)were significantly increased in BRD7^(−/−)MEF cells compared with BRD7+/+MEF cells after LPS stimulation for 1 or 6 h.In addition,the cytoplasm-to-nucleus translocation of nuclear factor kappa-B(NF-κB;p65)and an increased NF-κB reporter activity were observed in BRD7^(−/−)MEF cells at the 1 h time point but not at the 6 h time point.Furthermore,an in vivo dextran sodium sulfate(DSS)-induced acute colitis model was created.As expected,the disease activity index(DAI)value was significantly increased in the BRD7^(−/−)mice after DSS treatment for 1–5 days,which was demonstrated by the presence of a significantly shorter colon,splenomegaly and tissue damage.Moreover,higher expression levels of IL-6,TNF-α,p65,CXCL-1 and iNOS,and an increased level of NF-κB(p65)nuclear translocation were also found in the DSS-treated BRD7^(−/−)mice.These findings suggest that BRD7 has an anti-inflammatory role during early acute inflammation by inhibiting activation of the NF-кB signaling pathway,which provides evidence to aid in understanding the therapeutic effects of BRD7 on inflammatory diseases.Ran Zhao Yukun Liu Heran Wang Jing Yang Weihong Niu Songqing Fan Wei Xiong Jian Ma Xiaoling Li Joshua B Phillips Ming Tan Yuanzheng Qiu Guiyuan Li Ming Zhou 2017Cellular & Molecular Immunology2017,14,10:0
16Controlling factors of remaining oil distribution after water flooding and enhanced oil recovery methods for fracturecavity carbonate reservoirs in Tahe Oilfield显示文摘Based on comprehensive analysis of core, well logging, seismic and production data, the multi-scale reservoir space, reservoir types, spatial shape and distribution of fractures and caves, and the configuration relationship with production wells in fracture-cavity carbonate reservoirs were studied systematically, the influence of them on the distribution of residual oil was analyzed, and the main controlling factors mode of residual oil distribution after water flooding was established. Enhanced oil recovery methods were studied considering the development practice of Tahe oilfield. Research shows that the main controlling factors of residual oil distribution after water flooding in fracture-cavity carbonate reservoirs can be classified into four categories: local high point, insufficient well control, flow channel shielding and weak hydrodynamic. It is a systematic project to improve oil recovery in fracture-cavity carbonate reservoirs. In the stage of natural depletion, production should be well regulated to prevent bottom water channeling. In the early stage of waterflooding, injection-production relationship should be constructed according to reservoir type, connectivity and spatial location to enhance control and producing degree of waterflooding and minimize remaining oil. In the middle and late stage, according to the main controlling factors and distribution characteristics of remaining oil after water flooding, remaining oil should be tapped precisely by making use of gravity differentiation and capillary force imbibition, enhancing well control, disturbing the flow field and so on. Meanwhile, backup technologies of reservoir stimulation, new injection media, intelligent optimization etc. should be developed, smooth shift from water injection to gas injection should be ensured to maximize oil recovery.ZHENG Songqing YANG Min KANG Zhijiang LIU Zhongchun LONG Xibin LIU Kunyan LI Xiaobo ZHANG Shiliang 2019Petroleum Exploration and Development2019,46,4:0
17Targeted Poverty Alleviation and Justice显示文摘Poverty generally means a lack of material wealth,but this lack is often regarded as an evil,a symptom to be treated;thus,in the actual context,poverty reduction at all costs becomes a recognized good.Nevertheless,poverty may cause“evil”,but poverty itself does not mean evil.If multiple moral evaluations of poverty are eliminated,the impoverished individuals,especially those preferring to a lifestyle of rejection of material comforts can be looked at from a position of value-neutrality.In this way,poverty neither means evil nor deprivation of capabilities.Consequently,the ethical basis of the strategy,“Targeted Poverty Alleviation”should not be based on the moral judgment that“poverty is evil”or the ethical narrative that“poverty may lead to evil”,but rather“social justice”in this sense.Here I present an account that,“poverty”may take many forms in reality and“Targeted Poverty Alleviation”should have its restraint or limitations;meanwhile,defending the freedom and dignity of those who lack wealth is a more fundamental form of justice than reducing poverty.LIU Songqing CHEN Shuiying 2022Cultural and Religious Studies2022,10,5:0
18Bi_(2)O_(2)Se nanoplates for broadband photodetector and full-color imaging applications显示文摘Broadband light detection and sensing are widely applied in modern technology.As a promising candidate for next-generation two-dimensional(2D)optoelectronic material,bismuth oxyselenide(Bi_(2)O_(2)Se)nanoplates exhibit many prospects in the application of visible light detection due to their peculiar properties.In this work,we report the photodetection performance of single-crystal 2D Bi_(2)O_(2)Se nanoplates grown on SiO_(2)based on a ternary-alloy growth model by utilizing chemical vapor deposition(CVD).The Bi_(2)O_(2)Se nanoplates were found to have an even and uniform square shape with side lengths up to 15μm and an approximate thickness of 15 nm.A visible-light photodetector was fabricated based on a CVD-grown Bi_(2)O_(2)Se nanoplate,and characterized by a set of illumination experiments using a 400 nm laser at temperatures ranging from 77 to 370 K.The device exhibited superior performance at the temperature of 77 K,with a responsivity of 523 A/W,a specific detectivity of 1.37×10^(11)Jones,a response time of 0.2175 ms,an external quantum efficiency of 162,119.44%,resulting in high-quality and fullcolor imaging in the visible spectrum.These results indicate that the single-crystalline Bi_(2)O_(2)Se nanoplates have excellent potential in broadband photodetection and non-cryogenic imaging.Han Wang Songqing Zhang Xingxuan Wu Huijia Luo Junliang Liu Zesheng Mu Ruirui Liu Guang Yuan Yujun Liang Jin Tan Yongling Ren Wen Lei 2023Nano Research2023,16,5:0
