| 2 | Nomogram to predict overall survival after gallbladder cancer resection in China显示文摘AIM To integrate clinically significant variables related to prognosis after curative resection for gallbladder carcinoma(GBC) into a predictive nomogram.METHODS One hundred and forty-two GBC patients who underwent curative intent surgical resection at Peking Union Medical College Hospital(PUMCH) were included. This retrospective case study was conducted at PUMCH of the Chinese Academy of Medical Sciences and Peking Union Medical College(CAMS & PUMC) in China from January 1, 2003 to January 1, 2018. The continuous variable carbohydrate antigen 19-9(CA19-9) was converted into a categorical variable(cCA19-9) based on the normal reference range. Stages 0 to IIIA were merged into one category, while the remaining stages were grouped into another category. Pathological grade X(GX) was treated as a missing value. A multivariate Cox proportional hazards model was used to select variables to construct a nomogram. Discrimination and calibration of the nomogram were performed via the concordance index(C-index) and calibration plots. The performance of the nomogram was estimated using the calibration curve. Receiver operating characteristic(ROC) curve analysis and decision curve analysis(DCA) were performed to evaluate the predictive accuracy and net benefit of the nomogram, respectively.RESULTS Of these 142 GBC patients, 55(38.7%) were male, and the median and mean age were 64 and 63.9 years, respectively. Forty-eight(33.8%) patients in this cohort were censored in the survival analysis. The median survival time was 20 months. A series of methods, including the likelihood ratio test and Akaike information criterion(AIC) as well as stepwise, forward, and backward analyses, were used to select the model, and all yielded identical results. Jaundice [hazard ratio(HR) = 2.9; 95% confidence interval(CI): 1.60-5.27], cCA19-9(HR = 3.2; 95%CI: 1.91-5.39), stage(HR = 1.89; 95%CI: 1.16-3.09), and resection(R)(HR = 2.82; 95%CI: 1.54-5.16) were selected as significant predictors and combined into a survival time predictive nomogram(C-index = 0.803; 95%CI: 0.766-0.839). High prediction accuracy(adjusted C-index = 0.797) was further verified via bootstrap validation. The calibration plot demonstrated good performance of the nomogram. ROC curve analysis revealed a high sensitivity and specificity. A high net benefit was proven by DCA.CONCLUSION A nomogram has been constructed to predict the overall survival of GBC patients who underwent radical surgery from a clinical database of GBC at PUMCH. | Yi Bai Zhi-Song Liu Jian-Ping Xiong Wei-Yu Xu Jian-Zhen Lin Jun-Yu Long Fei Miao Han-Chun Huang Xue-Shuai Wan Hai-Tao Zhao | 2018 | World Journal of Gastroenterology2018，24，45： | 25 |
| 3 | Three-field vs two-field lymph node dissection for esophageal cancer:A meta-analysis显示文摘AIM:To assess the effects of 3-field lymphadenectomy for esophageal carcinoma.METHODS:We conducted a computerized literature search of the Pub Med,Cochrane Controlled Trials Register,and EMBASE databases from their inception to present.Randomized controlled trials(RCTs)or observational epidemiological studies(cohort studies)that compared the survival rates and/or postoperative complications between 2-field lymphadenectomy(2FL)and3-field lymphadenectomy(3FL)for esophageal carcinoma with R0 resection were included.Meta-analysis was conducted using published data on 3FL vs 2FL in esophageal carcinoma patients.End points were 1-,3-,and 5-year overall survival rates and postoperativecomplications,including recurrent nerve palsy,anastomosis leak,pulmonary complications,and chylothorax.Subgroup analysis was performed on the involvement of recurrent laryngeal lymph nodes.RESULTS:Two RCTs and 18 observational studies with over 7000 patients were included.There was a clear benefit for 3FL in the 1-(RR=1.16;95%CI:1.09-1.24;P<0.01),3-(RR=1.44;95%CI:1.19-1.75;P<0.01),and 5-year overall survival rates(RR=1.37;95%CI:1.18-1.59;P<0.01).For postoperative complications,3FL was associated with significantly more recurrent nerve palsy(RR=1.43;95%CI:1.28-1.60;P=0.02)and anastomosis leak(RR=1.26;95%CI:1.05-1.52;P=0.09).In contrast,there was no significant difference for pulmonary complications(RR=0.93;95%CI:0.75-1.16,random-effects model;P=0.27)or chylothorax(RR=0.77;95%CI:0.32-1.85;P=0.69).CONCLUSION:This meta-analysis shows that 3FL improves overall survival rate but has more complications.Because of the high heterogeneity among outcomes,definite conclusions are difficult to draw. | Guo-Wei Ma Dong-Rong Situ Qi-Long Ma Hao Long Lan-Jun Zhang Peng Lin Tie-Hua Rong | 2014 | World Journal of Gastroenterology2014，20，47： | 25 |
| 4 | Prognostic significance of combined preoperative fibrinogen and CA199 in gallbladder cancer patients显示文摘AIM To investigate the prognostic value of the combination of preoperative plasma fibrinogen and CA199 in patients with gallbladder carcinoma(GBC).METHODS The clinicopathological data of 154 GBC patients were retrospectively reviewed after surgery. A receiver operating characteristic(ROC) curve was plotted to verify the optimum cut-off values for plasma fibrinogen and CA199. Univariate and multivariate survival analyses were performed to identify the factors associated with GBC prognosis. based on the HRs calculated via multivariate survival analyses, patients with elevated plasma fibrinogen and CA199 levels were allocated a score of 2.1; those with an elevated plasma fibrinogen level only were allocated a score of 1, those with an elevated CA199 level only were allocated a score of 1.1, and those with neither of these abnormalities were allocated a score of 0.RESULTS ROC curve analysis showed that the optimum cut-off values for preoperative plasma fibrinogen and CA199 were 3.47 g/L and 25.45 U/mL, respectively. Multivariate analysis indicated that elevated preoperative plasma fibrinogen and CA199 levels were significantly correlated with worse overall survival(OS)(HR = 1.711, 95%CI: 1.114-2.627, P = 0.014, and HR = 1.842, 95%CI: 1.111-3.056, P = 0.018). When we combined these two parameters, the area under the ROC curve increased from 0.735(for preoperative plasma fibrinogen only) and 0.729(for preoperative CA199 only) to 0.765. When this combined variable was added to the multivariate analysis, the combination of plasma fibrinogen and CA199(P < 0.001), resection margin(P < 0.001) and TNM stage(P = 0.010) were independent prognostic factors for GBC.CONCLUSION The combination of plasma fibrinogen and CA199 may serve as a more efficient independent prognostic biomarker for postoperative GBC patients than either parameter alone. | Wei-Yu Xu Hao-Hai Zhang Xiao-Bo Yang Yi Bai Jian-Zhen Lin Jun-Yu Long Jian-Ping Xiong Jun-Wei Zhang Xin-Ting Sang Hai-Tao Zhao | 2018 | World Journal of Gastroenterology2018，24，13： | 24 |
| 5 | Prognostic significance of the fibrinogen-to-albumin ratio in gallbladder cancer patients显示文摘AIM To investigate the prognostic role of fibrinogen-toalbumin ratio(FAR) on patients with gallbladder cancer(Gbc) in this study.METHODS One hundred and fifty-four Gbc patients were retro-spectively analyzed, who received potentially curative cholecystectomy in our institute from March 2005 to December 2017. Receiver operating characteristic curve(ROc curve) was used to determine the optimal cut-offs for these biomarkers. In addition, Kaplan-Meier survival analysis as well as multivariate analysis were applied for prognostic analyses.RESULTS ROc curve revealed that the optimal cut-off value for FAR was 0.08. FAR was significantly correlated with age(P = 0.045), jaundice(P < 0.001), differentiation(P = 0.002), resection margin status(P < 0.001), T stage(P < 0.001), TNM stage(P < 0.001), and c A199(P < 0.001) as well as albumin levels(P < 0.001). Multivariate analysis indicated that the resection margin status [hazard ratio(HR): 2.343, 95% confidence interval(c I): 1.532-3.581, P < 0.001], TNM stage(P = 0.035), albumin level(HR = 0.595, 95%c I: 0.385-0.921, P = 0.020) and FAR(HR: 2.813, 95%c I: 1.765-4.484, P < 0.001) were independent prognostic factors in Gbc patients.CONCLUSION An elevated preoperative FAR was significantly correlated with unfavorable overall survival in Gbc patients, while an elevated preoperative albumin level was a protective prognostic factor for patients with Gbc. The preoperative FAR could be used to predict the prognosis of Gbc patients, which was easily accessible, costeffective and noninvasive. | Wei-Yu Xu Hao-Hai Zhang Jian-Ping Xiong Xiao-bo Yang Yi bai Jian-Zhen Lin Jun-Yu Long Yong-chang Zheng Hai-Tao Zhao Xin-Ting Sang | 2018 | World Journal of Gastroenterology2018，24，29： | 23 |
| 6 | Efficacy of intramuscular matrine in the treatment of chronic hepatitis B显示文摘BACKGROUND: Hepatitis B virus (HBV) infection, a glo- bal public health problem, is the leading cause of cirrhosis and hepatocellular carcinoma (HCC) worldwide. There are more than 350 million HBV carriers in the world and up to one million die annually due to hepatitis B associated liv- er disease. So far no optimal treatment is available for pa- tients with chronic hepatitis B. In the paper we investigated the efficacy of intramuscular matrine in the treatment of chronic hepatitis B. METHODS: One hundred and twenty patients with chronic hepatitis B were randomly divided into matrine treatment group (n =60) and control group (n =60). The patients of the matrine group were given intramuscularly with matrine (an alkaloid extracted from a traditional Chinese herb Radix Sophorae Flavescentis by Guangzhou Ming Xing Pharmaceu cal Factory, Guangzhou, China) of 100 mg daily for 90 days in addition to conventional liver-protective drugs in- cluding glucurone, inosine, compound vitamin B and caryophyllin. The control group received conventional liv- er-protective drugs alone. Clinical manifestations and labo- ratory parameters including liver biochemistry and serum hepatitis B virus markers were monitored before and after treatment in the two groups. RESULTS: Significant differences were seen between the two groups in terms of improvement of clinical symptoms and signs, recovery of liver functions, and serum conver- sion from hepatitis Be antigen to HBe antibody and from positive to negative serum HBV DNA (P <0.05-0.01). The result of the matrine group was more marked than that of the control group. Serious side-effects were not observed except mild pain at the site of injection of matrine in a few patients. CONCLUSION: These results indicate that intramuscular matrine may be an economical, efficacious, safe drug for the treatment of chronic hepatitis B. | Yao Long, Xiao-Tian Lin, Kun-Lun Zeng and Lian Zhang Zhanjiang, China Department of Infectious Diseases, Affiliated Hospital of Guangdong Medical College, Zhanjiang 524001, China Haibin Centre Hospital, Zhanjiang 524005, China Centre of Hepatology of Nanfang Hospital, First Military Medical University, Guang- zhou 510515, China | 2004 | Hepatobiliary & Pancreatic Diseases International2004，3，1： | 21 |
| 7 | Efficient production of omega-3 fatty acid desaturase (sFat-1)-transgenic pigs by somatic cell nuclear transfer显示文摘Omega-3(ω-3) fatty acid desaturase transgenic pigs may improve carcass fatty acid composition. The use of transgenic pigs is also an excellent large animal model for studying the role of ω-3 fatty acids in the prevention and treatment of coronary heart disease and cancer. Transgenic pigs carrying synthesized fatty acid desaturase-1 gene (sFat-1) from Caenorhabditis briggsae by somatic cell nuclear transfer (SCNT) were produced for the first time in China. Porcine fetal fibroblast cells were transfected with a sFat-1 expression cassette by the liposome-mediated method. Transgenic embryos were reconstructed by nuclear transfer of positive cells into enucleated in vitro matured oocytes. A total of 1889 reconstructed embryos were transferred into 10 naturally cycling gilts. Nine early pregnancies were established, 7 of which went to term. Twenty-one piglets were born. The cloning efficiency was 1.1% (born piglets/transferred embryos). The integration of the sFat-1 gene was confirmed in 15 live cloned piglets by PCR and Southern blot except for 2 piglets. Expression of the sFat-1 gene in 12 of 13 piglets was detected with RT-PCR. The data demonstrates that an efficient system for sFat-1 transgenic cloned pigs was developed, which led to the successful production of piglets expressing the sFat-1 gene. | PAN DengKe1, ZHANG Li1, ZHOU YanRong2, FENG Chong1, LONG Chuan1, LIU Xiao1, WAN Rong3, ZHANG Jian3, LIN AiXing3, DONG EnQiu4, WANG ShuChen4, XU HouGang4 & CHEN HongXing2 1 Institute of Animal Sciences, Chinese Academy of Agricultural Sciences, Beijing 100193, China 2 Beijing Institute of Biotechnology, Beijing 100071, China 3 China Agricultural University, Beijing 100193, China 4 Yutian Breeding Swine Farms, Yutian 064104, China | 2010 | Science China(Life Sciences)2010，53，4： | 21 |
| 8 | Synthesis of novel nanomaterials and their application in efficient removal of radionuclides显示文摘With the development of nuclear energy, large amounts of radionuclides are inevitably released into the natural environment. It is necessary to eliminate radionuclides from wastewater for the protection of environment. Nanomaterials have been considered as the potential candidates for the effective and selective removal of radionuclides from aqueous solutions under complicated conditions because of their high specific surface area, large amounts of binding sites, abundant functional groups, pore-size controllable and easily surface modification. This review mainly summarized the recent studies for the synthesis, fabrication and surface modification of novel nanomaterials and their applications in the efficient elimination and solidification of radionuclides,and discussed the interaction mechanisms from batch experiments, spectroscopy analysis and theoretical calculations. The sorption capacities with other materials, advantages and disadvantages of different nanomaterials are compared, and at last the perspective of the novel nanomaterials is summarized. | Xiangxue Wang Long Chen Lin Wang Qiaohui Fan Duoqiang Pan Jiaxing Li Fangting Chi Yi Xie Shujun Yu Chengliang Xiao Feng Luo Jun Wang Xiaolin Wang Changlun Chen Wangsuo Wu Weiqun Shi Shuao Wang Xiangke Wang | 2019 | Science China Chemistry2019，62，8： | 20 |

| 10 | Characterization of drug responses of mini patient-derived xenografts in mice for predicting cancer patient clinical therapeutic response显示文摘Background:Patient-derived organoids and xenografts(PDXs)have emerged as powerful models in functional diag-nostics with high predictive power for anticancer drug response.However,limitations such as engraftment failure and time-consuming for establishing and expanding PDX models followed by testing drug efficacy,and inability to subject to systemic drug administration for ex vivo organoid culture hinder realistic and fast decision-making in selecting the right therapeutics in the clinic.The present study aimed to develop an advanced PDX model,namely MiniPDX,for rapidly testing drug efficacy to strengthen its value in personalized cancer treatment.Methods:We developed a rapid in vivo drug sensitivity assay,OncoVee®MiniPDX,for screening clinically relevant regimens for cancer.In this model,patient-derived tumor cells were arrayed within hollow fiber capsules,implanted subcutaneously into mice and cultured for 7 days.The cellular activity morphology and pharmacokinetics were systematically evaluated.MiniPDX performance(sensitivity,specificity,positive and negative predictive values)was examined using PDX as the reference.Drug responses were examined by tumor cell growth inhibition rate and tumor growth inhibition rate in PDX models and MiniPDX assays respectively.The results from MiniPDX were also used to evaluate its predictive power for clinical outcomes.Results:Morphological and histopathological features of tumor cells within the MiniPDX capsules matched those both in PDX models and in original tumors.Drug responses in the PDX tumor graft assays correlated well with those in the corresponding MiniPDX assays using 26 PDX models generated from patients,including 14 gastric cancer,10 lung cancer and 2 pancreatic cancer.The positive predictive value of MiniPDX was 92%,and the negative predictive value was 81%with a sensitivity of 80%and a specificity of 93%.Through expanding to clinical tumor samples,Min-iPDX assay showed potential of wide clinical application.Conclusions:Fast in vivo MiniPDX assay based on capsule implantation was developed-to assess drug responses of both PDX tumor grafts and clinical cancer specimens.The high correlation between drug responses of paired MiniPDX and PDX tumor graft assay,as well as translational data suggest that MiniPDX assay is an advanced tool for personalized cancer treatment. | Feifei Zhang Wenjie Wang Yuan Long Hui Liu Jijun Cheng Lin Guo Rongyu Li Chao Meng Shan Yu Qingchuan Zhao Shun Lu Lili Wang Haitao Wang Danyi Wen | 2018 | Cancer Communications2018，38，1： | 20 |
| 11 | Measurement-device-independent quantum communication without encryption显示文摘Security in communication is vital in modern life. At present, security is realized by an encryption process in cryptography. It is unbelievable if a secure communication is achievable without encryption. In quantum cryptography, there is a unique form of quantum communication, quantum secure direct communication, where secret information is transmitted directly over a quantum channel. Quantum secure direct communication is drastically distinct from our conventional concept of secure communication, because it does not require key distribution, key storage and ciphertext transmission, and eliminates the encryption procedure completely. Hence it avoids in principle all the security loopholes associated with key and ciphertext in traditional secure communications. For practical implementation, defects always exist in real devices and it may downgrade the security. Among the various device imperfections, those with the measurement devices are the most prominent and serious ones. Here we report a measurementdevice-independent quantum secure direct communication protocol using Einstein-Podolsky-Rosen pairs. This protocol eradicates the security vulnerabilities associated with the measurement device,and greatly enhances the practical security of quantum secure direct communication. In addition to the security advantage, this protocol has an extended communication distance, and a high communication capacity. | Peng-Hao Niu Zeng-Rong Zhou Zai-Sheng Lin Yu-Bo Sheng Liu-Guo Yin Gui-Lu Long | 2018 | Science Bulletin2018，63，20： | 19 |

| 13 | A kinetic study of the reaction of ozone with ethylene in a smog chamber under atmospheric conditions显示文摘Ozone is one of the key species in the processes of atmospheric chemistry, which can be taken as an indicator of oxidation capacity in the troposphere. The reaction of ozone with reactive gases is an important process in the troposphere. Experimental simulation equipment of smog chamber for atmospheric reactions is used to study the reaction of ozone with ethylene in real atmospheric environment with ozone concentrations of 100―200 ppb. The concentrations of ozone and ethylene were moni-tored during the reaction with the combination of Model 49C-O_3 Analyzer and GC-FID. A rate constant of 1.01×10^(-18) (cm^3·mol^(-1)·s-(~1)) was obtained at 286.5 K, under condition of which the half-life of ozone was 88 min. The results obtained from our experiments are in excellent agreement with those reported previously by other researchers under extremely low pressure in terms of matrixisolation technology. This demonstrates that our equipment of smog chamber for atmospheric reactions is reliable, which can be used for further research of the processes of atmospheric reactions. | XU Yongfu JIA Long GE Maofa DU Lin WANG Gengchen WANG Dianxun | 2006 | Chinese Science Bulletin2006，51，23： | 16 |
| 14 | Implementation and security analysis of practical quantum secure direct communication显示文摘Rapid development of supercomputers and the prospect of quantum computers are posing increasingly serious threats to the security of communication.Using the principles of quantum mechanics,quantum communication offers provable security of communication and is a promising solution to counter such threats.Quantum secure direct communication(QSDC)is one important branch of quantum communication.In contrast to other branches of quantum communication,it transmits secret information directly.Recently,remarkable progress has been made in proof-of-principle experimental demonstrations of QSDC.However,it remains a technical feat to bring QSDC into a practical application.Here,we report the implementation of a practical quantum secure communication system.The security is analyzed in the Wyner wiretap channel theory.The system uses a coding scheme of concatenation of lowdensity parity-check(LDPC)codes and works in a regime with a realistic environment of high noise and high loss.The present system operates with a repetition rate of 1 MHz at a distance of 1.5 kilometers.The secure communication rate is 50 bps,sufficient to effectively send text messages and reasonably sized files of images and sounds. | Ruoyang Qi Zhen Sun Zaisheng Lin Penghao Niu Wentao Hao Liyuan Song Qin Huang Jiancun Gao Liuguo Yin Gui-Lu Long | 2019 | Light(Science & Applications)2019，8，1： | 15 |
| 15 | Multiple primary malignant tumors of upper gastrointestinal tract:A novel role of ^(18)F-FDG PET/CT显示文摘AIM: To evaluate the capacity of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for detecting multiple primary cancer of upper gastrointestinal (UGI) tract. METHODS: Fifteen patients (12 without cancer histories and 3 with histories of upper GI tract cancer) were investigated due to the suspicion of primary cancer of UGI tract on X-ray barium meal and CT scan. Subsequent whole body 18F-FDG PET/CT scan was carried out for initial staging or restaging. All the patients were fi nally confi rmed by endoscopic biopsy or surgery. The detection rate of multiple primary malignant cancers was calculated based on 18F-FDG PET/CT and endoscopic examinations.RESULTS: 18F-FDG PET/CT scan was positive in 32 suspicious lesions, 30/32 were true positive primary lesions, and 2/32 were false positive. In 15 suspicious lesions with negative 18F-FDG PET/CT scan, 12/15 were true negative and 3/15 were false negative. Among the 15 patients, 12 patients had 29 primary synchronous tumors confirmed by pathology, including 8 cases of esophageal cancers accompanied with gastric cancer and 4 of hypopharynx cancers with esophageal cancer. The other 3 patients had 4 new primary metachronous tumors, which were multiple primary esophageal cancers. PET/CT imaging detected local lymph node metastases in 11 patients. Both local lymph node metastases and distant metastases were detected in 4 patients. On a per-primary lesion basis, the sensitivity, specificity, accuracy, negative predictive value and positive predictive value of 18F-FDG PET/CT for detecting multiple primary cancer of UGI tract were 90.9%, 85.7%, 89.4%, 80% and 93.7%, respectively. CONCLUSION: The whole body 18F-FDG PET/CT may play an important role in evaluating the multiple primary malignant tumors of UGI tract cancer. | Long Sun Yong-Hong Sun Long Zhao Zuo-Ming Luo Hua Wu Ying Wan Qin Lin | 2010 | World Journal of Gastroenterology2010，16，31： | 14 |
| 16 | Notch signaling pathway:architecture,disease,and therapeutics显示文摘The NOTCH gene was identified approximately 110 years ago.Classical studies have revealed that NOTCH signaling is an evolutionarily conserved pathway.NOTCH receptors undergo three cleavages and translocate into the nucleus to regulate the transcription of target genes.NOTCH signaling deeply participates in the development and homeostasis of multiple tissues and organs,the aberration of which results in cancerous and noncancerous diseases.However,recent studies indicate that the outcomes of NOTCH signaling are changeable and highly dependent on context.In terms of cancers,NOTCH signaling can both promote and inhibit tumor development in various types of cancer.The overall performance of NOTCH-targeted therapies in clinical trials has failed to meet expectations.Additionally,NOTCH mutation has been proposed as a predictive biomarker for immune checkpoint blockade therapy in many cancers.Collectively,the NOTCH pathway needs to be integrally assessed with new perspectives to inspire discoveries and applications.In this review,we focus on both classical and the latest findings related to NOTCH signaling to illustrate the history,architecture,regulatory mechanisms,contributions to physiological development,related diseases,and therapeutic applications of the NOTCH pathway.The contributions of NOTCH signaling to the tumor immune microenvironment and cancer immunotherapy are also highlighted.We hope this review will help not only beginners but also experts to systematically and thoroughly understand the NOTCH signaling pathway. | Binghan Zhou Wanling Lin Yaling Long Yunkai Yang Huan Zhang Kongming Wu Qian Chu | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 14 |

| 18 | Reconfigurable intelligent surfaces for smart wireless environments:channel estimation,system design and applications in 6G networks显示文摘Reconfigurable intelligent surface(RIS),one of the key enablers for the sixth-generation(6G)mobile communication networks,is considered by designers to smartly reconfigure the wireless propagation environment in a controllable and programmable manner.Specifically,an RIS consists of a large number of low-cost and passive reflective elements(REs)without radio frequency chains.The system gain of RIS wireless systems can be achieved by adjusting the phase shifts and amplitudes of the REs so that the desired signals can be added constructively at the receiver.However,an RIS typically has limited signal processing capability and cannot perform active transmitting/receiving in general,which leads to new challenges in the physical layer design of RIS wireless systems.In this paper,we provide an overview of the RIS-aided wireless systems,including the reflection principle,channel estimation,and system design.In particular,two types of emerging RIS systems are considered:RIS-aided wireless communications(RAWC)and RISbased information transmission(RBIT),where the RIS plays the role of the reflector and the transmitter,respectively.We also envision the potential applications of RIS in 6G networks. | Ying-Chang LIANG Jie CHEN Ruizhe LONG Zhen-Qing HE Xianqi LIN Chenlu HUANG Shilin LIU Xuemin(Sherman)SHEN Marco DI RENZO | 2021 | Science China(Information Sciences)2021，64，10： | 12 |
| 19 | Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area. | Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG | 2018 | Science China Earth Sciences2018，61，11： | 12 |
| 20 | Facile synthesis of ultrathin metal-organic framework nanosheets for Lewis acid catalysis显示文摘Ultrathin metalorganic framework (MOF) nanosheets are attracting great interest in catalysis due to their unique and intriguing two-dime nsional (2D) features. Although many progresses have been achieved, it is still highly desirable to develop novel strategies for controllable synthesis of the well-defined ultrathin MOF nanosheets. Herein we report a polyvinylpyrrolidone (PVP)-assisted route to synthesize the ultrathin Ni-MOF nanosheets characteristic of 1.5 nm in thickness, in which PVP is reacted with 2-aminoterephthalic acid (H2BDC-NH2) via formation of C=N bon d, followed by coord inatio n with Ni2+ io ns to form the ultrathi n MOF n anosheets. Impressively, when used in the Kno eve nagel condensation reactions of propane dinitrile with different aldehydes, ultrathin Ni-MOF nanosheets display the significantly enhanced catalytic activity and good stability in respect with the bulk Ni-MOF, mainly owing to the exposed active sites as well as facile mass transfer and diffusion of substrates and products. | Xiaofei Zhang Lin Chang Zhongjie Yang Yanan Shi Chang Long Jianyu Han Binhao Zhang Xueying Qiu Guodong Li Zhiyong Tang | 2019 | Nano Research2019，12，2： | 11 |
