1Ultrasound-Guided Transmuscular Quadratus Lumbar Block Reduces Opioid Consumption after Laparoscopic Partial Nephrectomy显示文摘Objectives Transmuscular quadratus lumborum block(TQLB)may provide postoperative analgesia in patients undergoing intraperitoneal surgeries.The purpose of this study was to examine the potential efficacy of TQLB among patients undergoing retroperitoneal procedures,such as the laparoscopic partial nephrectomy(LPN).Methods This prospective,randomized,controlled study was conducted from August 2017 to November 2018 at Peking Union Medical College Hospital(Beijing,China).Patients who were scheduled for a LPN,aged 18・70 years old with an ASA physical status score of I-II were randomly assigned to receive either TQLB with 0.6 ml/kg of 0.5%ropivacaine plus general anesthesia(TQLB group)or general anesthesia alone(control group).Patient-controlled intravenous analgesia with morphine was initiated immediately upon surgery completion.The primary outcome was the cumulative consumption of morphine within 8 h after surgery.The secondary outcome included postoperative consump廿ons of morphine at other time points,pain score at rest and during activity,postoperative nausa and vomitting(PONV),and recovery related parameters.Results Totally 30 patients per group were recruited in the study.The 8 h consumption of morphine was lower in theTQLB group than in the control group(median,0.023 mg/kg vs.0.068 mg/kg,U=207.5,P<0.001).No significant differences were observed in postoperative pain scores between the two groups.Patients in the TQLB group had fewer episodes of PONV(20%vs.47%,χ2=4.&P=0.028)in the first 24 h after surgery and higher scores for quality of recovery(mean,13&6 vs.131.9,t=-2.164,P=0.035)120 h after surgery than the controls.Conclusions TQLB resulted in an opioid-sparing effect during the early postoperative period following LPN,as well as a lower incidence of PONV and improved quality of recovery.Xulei Cui Xu Li Minna Li Yuelun Zhang Yi Xie Weigang Yan Yushi Zhang Zhigang Ji Yuguang Huang 2020Chinese Medical Sciences Journal2020,35,4:10
2Tim-3 promotes cell aggressiveness and paclitaxel resistance through NF-κB/STAT3 signalling pathway in breast cancer cells显示文摘Objective:Although T-cell immunoglobulin and mucin-domain containing molecule-3(Tim-3)has been recognized as a promising target for cancer immunotherapy,its exact role in breast cancer has not been fully elucidated.Methods:Tim-3 gene expression in breast cancer and its prognostic significance were analyzed.Associated mechanisms were then explored in vitro by establishing Tim-3-overexpressing breast cancer cells.Results:In a pooled analysis of The Cancer Genome Atlas(TCGA)database,Tim-3 gene expression levels were significantly higher(P<0.001)in breast cancer tissue,compared with normal tissues.Tim-3 was a prognosis indicator in breast cancer patients[relapse-free survival(RFS),P=0.004;overall survival(OS),P=0.099].Tim-3 overexpression in Tim-3 low breast cancer cells promoted aggressiveness of breast cancer cells,as evidenced by enhanced proliferation,migration,invasion,tight junction deterioration and tumor-associated tubal formation.Tim-3 also enhanced cellular resistance to paclitaxel.Furthermore,Tim-3 exerted its function by activating the NF-κB/STAT3 signalling pathway and by regulating gene expression[cyclin D1(CCND1),C-Myc,matrix metalloproteinase-1(MMP1),TWIST,vascular endothelial growth factor(VEGF)upregulation,concomitant with Ecadherin downregulation).Lastly,Tim-3 downregulated tight junction-associated molecules zona occludens(ZO)-2,ZO-1 and occludin,which may further facilitate tumor progression.Conclusions:Tim-3 plays an oncogenic role in breast cancer and may represent a potential target for antitumor therapy.Yizi Cong Yuxin Cui Shiguang Zhu Jianqiao Cao Haidong Zou Tracey AMartin Guangdong Qiao Wenguo Jiang Zhigang Yu 2020Chinese Journal of Cancer Research2020,32,5:7
3A multi-institutional retrospective study of hyperthermic plus intravesical chemotherapy versus intravesical chemotherapy treatment alone in intermediate and high risk nonmuscle-invasive bladder cancer显示文摘Objective:To compare the efficacy and safety of hyperthermic intravesical chemotherapy(HIVEC)and intravesical chemotherapy(IVEC)in patients with intermediate and high risk nonmuscle-invasive bladder cancer(NMIBC)after transurethral resection.Methods:We included 560 patients diagnosed with primary or recurrent NMIBC between April 2009 and December 2015 at 1 of 6 tertiary centers.We matched 364 intermediate or high risk cases and divided them into 2 groups:the HIVEC+IVEC group[chemohyperthermia(CHT)composed of 3 consecutive sessions followed by intravesical instillation without hyperthermia]and the IVEC group(intravesical instillation without hyperthermia).The data were recorded in the database.The primary endpoint was 2-year recurrence-free survival(RFS)in all NMIBC patients(n=364),whereas the secondary endpoints were the assessment of radical cystectomy(RC)and 5-year overall survival(OS).Results:There was a significant difference in the 2-year RFS between the two groups in all patients(n=364;HIVEC+IVEC:82.42%vs.IVEC:74.18%,P=0.038).Compared with the IVEC group,the HIVEC+IVEC group had a lower incidence of RC(P=0.0274).However,the 5-year OS was the same between the 2 groups(P=0.1434).Adverse events(AEs)occurred in 32.7%of all patients,but none of the events was serious(grades 3–4).No difference in the incidence or severity of AEs between each treatment modality was observed.Conclusions:This retrospective study showed that HIVEC+IVEC had a higher 2-year RFS and a lower incidence of RC than IVEC therapy in intermediate and high risk NMIBC patients.Both treatments were well-tolerated in a similar manner.Qiang Ruan Degang Ding Bin Wang Chaohong He Xuequn Ren Zhenhua Feng Zhigang Pang Jin Wang Xiangliang Zhang Hongsheng Tang Jiahong Wang Qingjun He Ziying Lei Quanxing Liao Jiali Luo Shuzhong Cui 2021Cancer Biology & Medicine2021,18,1:4
4Influence of Sb_2O_3 doping on the properties of KBT-NBT-BT lead-free piezoelectric ceramics显示文摘0.144(K0.5Bi0.5)TiO3-0.85(Na0.5Bi0.5)TiO3-0.006BaTiO3(KBT-NBT-BT) lead-free piezoelectric ceramics were prepared using a conventional solid state method.The influence of Sb2O3 doping on the crystal phase,surface microstructure and properties of the KBT-NBT-BT lead-free piezoelectric ceramics were investigated using X-ray diffraction(XRD),scanning electron microscope(SEM) and other analytical methods.The results show that all compositions are of pure perovskite structure solid states.Sb2O3 doping does not influence the microstructure of KBT-NBT-BT lead-free piezoelectric ceramics obviously in the Sb2O3 doping range of 0.1-0.5 wt.%.Sb2O3 functions as a donor when doped small amount,while functions as a acceptor when doped large amount.The piezoelectric strain constant(d33) increases first and then decreases;the dielectric constant(ε3T3/ε0) and the dielectric loss(tanδ) decrease continuously when the amount of Sb2O3 dopant increases.When the doping amount of Sb2O3 is 0.1 wt.%,the KBT-NBT-BT piezoelectric ceramics with good comprehensive properties are obtained,whose d33,ε3T3/ε0 and tanδ are 147 pC/N,1510 and 4.2%,respectively.HUANG Xinyou GAO Chunhua WEI Minxian CHEN Zhigang CUI Yongzhen 2011Rare Metals2011,30,1:4
5PulseNet China,a model for future laboratory-based bacterial infectious disease surveillance in China显示文摘Surveillance is critical for the prevention and control of infectious disease.China’s real-time web-based infectious disease reporting system is a distinguished achievement.However,many aspects of the current China Infectious Disease Surveillance System do not yet meet the demand for timely outbreak detection and identification of emerging infectious disease.PulseNet,the national molecular typing network for foodborne disease surveillance was first established by the Centers for Disease Control and Prevention of the United States in 1995 and has proven valuable in the early detection of outbreaks and tracing the pathogen source.Since 2001,the China CDC laboratory for bacterial pathogen analysis has been a member of the PulseNet International family;and has been adapting the idea and methodology of PulseNet to develop a model for a future national laboratory-based surveillance system for all bacterial infectious disease.We summarized the development progress for the PulseNet China system and discussed it as a model for the future of China’s national laboratory-based surveillance system.Wei Li Shan Lu Zhigang Cui Jinghua Cui Haijian Zhou Yiqing Wang Zhujun Shao Changyun Ye Biao Kan Jianguo Xu 2012Frontiers of Medicine2012,6,4:4

7Cholecystectomy is associated with higher risk of recurrence after microwave ablation of hepatocellular carcinoma:a propensity score matching analysis显示文摘Objective:To explore the association between cholecystectomy and the prognostic outcomes of patients with hepatocellular carcinoma(H CC)who underwent microwave ablation(MWA).Methods:Patients with HCC(«=921)who underwent MWA were included and divided into cholecystectomy(n=114)and non-cholecystectomy groups(n=807).After propensity score matching(PSM)at a 1:2 ratio,overall survival(OS)and disease-free survival(DFS)rates were analyzed to compare prognostic outcomes between the cholecystectomy(«=114)and non-cholecystectomy groups(n=228).Univariate and multivariate Cox analyses were performed to assess potential risk factors for OS and DFS.Major complications were also compared between the groups.Results:After matching,no significant differences between groups were observed in baseline characteristics.The 1-,3-,and 5-year OS rates were 96.5%,82.1%,and 67.1%in the cholecystectomy group,and 97.4%,85.2%,and 74.4%in the non-cholecystectomy group(P=0.396);the 1-,3-,and 5-year DFS rates were 58.4%,34.5%,and 26.6%in the cholecystectomy group,and 73.6%,44.7%,and 32.2%in the non-cholecystectomy group(P=0.026),respectively.The intrahepatic distant recurrence rate in the cholecystectomy group was significantly higher than that in the non-cholecystectomy group(P=0.026),and the local tumor recurrence and extrahepatic recurrence rates did not significantly differ between the groups(P=0.609 and P=0.879).Multivariate analysis revealed that cholecystectomy(HR=1.364,95%Cl 1.023-1.819,P=0.035),number of tumors(2 vs.1:HR=2.744,95%Cl 1.925-3.912,P<0.001;3 vs.1:HR=3.411,95%Cl 2.021-5.759,P<0.001),and y-GT levels(HR=1.003,95%Cl 1.000-1.006,P<0.024)were independent risk factors for DFS.The best y-GT level cut-off value for predicting median DFS was 39.6 U/L(area under the curve=0.600,P<0.05).A positive correlation was observed between cholecystectomy and y-GT level(r=0.108,95%Cl-0.001-0.214,P=0.047).Subgroup analysis showed that the DFS rates were significantly higher in the non-cholecystectomy group than the cholecystectomy group when Y-GT>39.6 U/L(i3=0.044).The 5-,10-,15-,20-,and 25-year recurrence rates from the time of cholecystectomy were 2.63%,21.93%,42.11%,58.77%,and 65.79%,respectively.A significant positive correlation was observed between cholecystectomy and the time from cholecystectomy to recurrence(r=0.205,95%Cl 0.016-0.379,P=0.029).There were no significant differences in complications between groups(P=0.685).Conclusions:Patients with HCC who underwent cholecystectomy were more likely to develop intrahepatic distant recurrence after MWA,an outcome probably associated with increased y-GT levels.Moreover,the recurrence rates increased with time.Hongcai Yang Yi Yang Jianping Dou Rui Cui Zhigang Cheng Zhiyu Han Fangyi Liu Xiaoling Yu Xiang Zhou Jie Yu Ping Liang 2020Cancer Biology & Medicine2020,17,2:3
8Cholera Caused by a New Clone of Serogroup O1 Vibrio cholerae-Beijing Municipality,China,June 2021显示文摘Several lineages have been identified in the population of serogroup O1 Vibrio cholerae(V.cholerae)(1-3).The strains,which were responsible for the ongoing seventh cholera pandemic,were in Lineage 2.Nearly all the V.cholerae strains in this lineage carried genes coding cholera toxin(ctxAB)(1-2).Lineage 3b consists of strains isolated from different continents and the vast majority of strains in this lineage lack the ctxAB genes.Hanqiu Yan Bo Pang Xin Lu Zhiyong Gao Pan Lu Xin Zhang Mengyu Wang Lingyu Shen Wenxuan Zhao Jianhong Zhao Weili Liang Lei Jia Haijian Zhou Zhigang Cui Xiaoli Du Biao Kan Quanyi Wang 2022China CDC weekly2022,4,2:3
9Chinese Pathogen Identification Net:A Laboratory Network for Surveillance and Response of Bacterial Infectious Diseases显示文摘Infectious diseases are a sustained threat to social development and public health.Bacterial infectious diseases,including plague,cholera,anthrax,brucellosis,typhoid fever,meningitis,and even those caused by antimicrobial-resistant bacteria,have been prevalent around the world for a long time,and still trigger outbreaks and long-term epidemics in different countries or regions nowadays(1),and trans-regional spread of diseases has frequently exhibited epidemic patterns.Zhigang Cui Haijian Zhou Shuang Meng Xiaoli Du Jianguo Xu Biao Kan 2022China CDC weekly2022,4,12:2
10Cenozoic Sea-land Transition and its Petroleum Geological Significance in the Northern South China Sea显示文摘The process of Cenozoic sea-land changes in the northern South China Sea(SCS)controlled the sedimentary filling pattern and played an important role in the petroleum geological characteristics of the northern marginal sedimentary basins.Under the control of the opening process of the SCS,the northern SCS Cenozoic transgression generally showed the characteristics of early in the east and late in the west,and early in the south and late in the north.The initial transgression occurred in the Eocene in the Taixinan Basin(TXNB)of the eastern SCS,while the transgression occurred until the Pliocene in the Yinggehai Basin(YGHB)of the western SCS.International Ocean Discovery Program(IODP)expeditions(Expeditions 367/368)revealed that the initial transgression of the SCS basin occurred at approximately 34 Ma,which was the initial opening time of the SCS.The period of drastic changes in the sedimentary environment caused by large-scale transgression corresponded to the opening time of the southwestern subbasin(approximately 23 Ma),which also represented the peak of the spreading of the SCS.The sea-land transition process controls the distribution of alternating continent-marine facies,marine facies source rocks and reservoirs in the basins.The marine facies source rocks of the basins in the northern SCS have a trend of gradually becoming younger from east to west,which is consistent with the regional process of gradual transgression from east to west.Regional sea-level changes were comprehensively influenced by SCS opening and global sea-level changes.These processes led to the early development in the east and south and late development in the west and north for the carbonate platform in the SCS.Carbonate platforms form another type of'selfgenerating and self-accumulating'oil-gas reservoir in the northern SCS.The sea-land transition controlled the depositional filling patterns of different basins and laid the foundation of marine deposits for oil and gas resources.The source-reservoircap assemblage in the northern SCS was controlled horizontally by provenance supply and sedimentary environmental changes caused by sea-land transition and vertically by the tectonic evolution of the SCS and regional sea-level changes.ZHAO Zhigang ZHANG Hao CUI Yuchi TANG Wu QIAO Peijun 2021Acta Geologica Sinica(English Edition)2021,95,1:2
11Geochemical Constrains on MORB Composition and Magma Sources at East Pacific Rise Between 1°S and 2°S显示文摘The East Pacific Rise(EPR)is a typical fast spreading ridge.To gain a better understanding of the magmatism under ridges,Mid Ocean Ridge Basalts(MORBs)with remarkably heterogeneous compositions are obtained from(EPR)1?–2?S and multielement geochemical and radioisotope analyses are conducted.Results show that these MORBs have wide variation ranges in trace element concentrations and isotopic ratios.Sample 07 has low concentrations of incompatible elements,and very low ^(87)Sr/^(86)Sr,and high ^(143)Nd/^(144)Nd from 0.70213 to 0.702289 and 0.513234 to 0.513289,respectively.However,other samples show enrichment in incompatible elements to varying degrees,and medium values of ^(87)Sr/^(86)Sr and ^(143)Nd/^(144)Nd from 0.702440 to 0.702680 and 0.513086to 0.513200,respectively.This study proposes that one depleted source and two enriched sources contribute to the formation of MORBs from EPR 1?–2?S.Samples 02 and 10 are formed by mixing between one enriched source and one depleted source,while sample 07 is crystallized from the depleted source with no mixing process involved.However,the formation of samples 06 and 11are different,and thus further research is required to determine genesis.ZHANG Wei ZENG Zhigang CUI Lukai YIN Xuebo 2018Journal of Ocean University of China2018,17,2:2
