| 1 | Reconstruction of precipitation variation from tree rings in recent 1000 years in Delingha, Qinghai显示文摘Using seven well-replicated Qilian juniper (Sabina przewalskii Kom.) ring-width chronologies developed at Zongwulong and Shalike Mts. in the northeastern part of the Qaidam Basin annual precipitation from previous July to current June in the recent 1000 years was re- constructed for Delingha. The reconstruction can capture 63.1% of precipitation variance and the equation was stable over time. For the reconstructed precipitation, wet periods occurred in AD1520—1633 and 1933—2001, whereas dry intervals in 1429—1519 and 1634—1741. In ad- dition, the magnitude in precipitation variation was lower before 1430 with about 15 mm, but it increased to 30 mm during the period of 1430 to 1850. After 1850, the precipitation variance de- creased again. In contrast to the increase in temperature, a decrease in annual precipitation was evident since the 1990s. The agreement in low-frequency variation between the reconstruction and the glacier accumulation and particulate content in Dunde ice cores during the recent several hundred years suggested that the precipitation reconstructed in this study was rather reliable, and represented a regional signal. This 1000-year reconstruction could benefit our understanding of climatic variation in decadal to century-scale in this region, and provide basic data to climate models and to prediction of future climate in the 21st century. | SHAO Xuemei1, HUANG Lei1, LIU Hongbin2, LIANG Eryuan1, FANG Xiuqi3 & WANG Lili1 1.

| 4 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021,64,1: | 122 |
| 5 | Oxygen depletion off the Changjiang (Yangtze River)Estuary显示文摘In a survey on the Yellow Sea and the East China Sea on August 20-30 of 1999, we found a hypoxic zone (<2 mg/L) of 13700 km2 with an average thickness of 20m at the bottom of the Changjiang (Yangtze River) Estuary, with an oxygen minimum value of 1 mg/L. The extension of the dissolved oxygen deficiency extended to the 100m isobath in a southeastward direction along the bottom of the continental shelf of the East China Sea. During the last two decades, the minimum dissolved oxygen values in the low oxygen region of the Changjiang Estuary have decreased from 2.85 mg/L to 1 mg/L. In the hypoxic zone, the apparent oxygen utilization (AOU) was 5.8 mg/L and the total oxygen depletion approximately 1.59×106 t. The strong halocline above the hypoxic zone, as a result of affluent water from the Changjiang, Taiwan Warm Current (TWC), and the high concentrations of particle organic carbon (POC) and nitrogen (PON) are the major factors causing the formation of the hypoxic zone. The POC: PON ratios and nutrient concentration distributions in the hypoxic zone suggest that the oxygen deficiency in the bottom water during the summer in the East China Sea off the Changjiang is the result of organic carbon production enhanced by nutrients from the Changjiang and fluvial organic matter input, followed by a shift in regeneration of nutrients in the East China Sea. | LI Daoji (李道季) ZHANG Jing (张经) HUANG Daji (黄大吉) WU Ying (吴莹) LIANG Jun (梁俊) | 2002 | Science China Earth Sciences2002,45,12: | 80 |

| 7 | China’s urban expansion from 1990 to 2010 determined with satellite remote sensing显示文摘Based on the same data source of Landsat TM/ETM+ in 1990s,2000s and 2010s,all urban built-up areas in China are mapped mainly by human interpretation.Mapping results were checked and refined by the same analyst with the same set of criteria.The results show during the last 20 years urban areas in China have increased exponentially more than 2 times.The greatest area of urbanization changed from Northeastern provinces in 1990s to the Southeast coast of China in Jiangsu,Guangdong,Shandong,and Zhejiang in 2010s.Urban areas are mostly converted from croplands in China.Approximately 17750 km 2 croplands were converted into urban lands.Furthermore,the conversion from 2000 to 2010 doubled that from 1990 to 2000.During the 20 years,the most urbanized provinces are Jiangsu,Guangdong,Shandong and Zhejiang.We also analyzed built-up areas,gross domestic production (GDP) and population of 147 cities with a population of greater than 500000 in 2009.The result shows coastal cities and resource-based cities are with high economic efficiency per unit of built-up areas,resource-based cities have the highest population density,and the economic efficiency of most coastal provinces are lower than central provinces and Guangdong.The newly created urban expansion dataset is useful in many fields including trend analysis of urbanization in China;simulation of urban development dynamics;analysis of the relationship among urbanization,population growth and migration;studies of carbon emissions and climate change;adaptation of climate change;as well as land use and urban planning and management. | WANG Lei LI CongCong YING Qing CHENG Xiao WANG XiaoYi LI XueYan HU LuanYun LIANG Lu YU Le HUANG HuaBing GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 64 |
| 8 | Remediation of Heavy Metal-Polluted Agricultural Soils Using Clay Minerals: A Review显示文摘Heavy metal contamination of agricultural soils poses risks and hazards to humans. The remediation of heavy metal-polluted soils has become a hot topic in environmental science and engineering. In this review, the application of clay minerals for the remediation of heavy metal-polluted agricultural soils is summarized, in terms of their remediation effects and mechanisms, influencing factors,and future focus. Typical clay minerals, natural sepiolite, palygorskite, and bentonite, have been widely utilized for the in-situ immobilization of heavy metals in soils, especially Cd-polluted paddy soils and wastewater-irrigated farmland soils. Clay minerals are able to increase soil p H, decrease the chemical-extractable fractions and bioavailability of heavy metals in soils, and reduce the heavy metal contents in edible parts of plants. The immobilization effects have been confirmed in field-scale demonstrations and pot trials. Clay minerals can improve the environmental quality of soils and alleviate the hazards of heavy metals to plants. As main factors affecting the immobilization effects, the p H and water condition of soils have drawn academic attention. The remediation mechanisms mainly include liming, precipitation, and sorption effects. However, the molecular mechanisms of microscopic immobilization are unclear. Future studies should focus on the long-term stability and improvement of clay minerals in order to obtain a better remediation effect. | XU Yi LIANG Xuefeng XU Yingming QIN Xu HUANG Qingqing WANG Lin SUN Yuebing | 2017 | Pedosphere2017,27,2: | 66 |
| 9 | Concentration and source identification of polycyclic aromatic hydrocarbons and phthalic acid esters in the surface water of the Yangtze River Delta,China显示文摘The pollution from polycyclic aromatic hydrocarbons(PAHs) and phthalic acid esters(PAEs) in the surface water of the rapidly urbanized Yangtze River Delta region was investigated.Fourteen surface water samples were collected in June 2010.Water samples were liquid-liquid extracted using methylene chloride and analyzed by gas chromatography-mass spectrometry.Concentrations of PAHs and PAEs ranged 12.9-638.1 ng/L and 61-28550 ng/L,respectively.Fluoranthene,naphthalene,pyrene,phenanthrene,di-2ethylhexyl phthalate,and di-n-butyl phthalate were the most abundant compounds in the samples.The water samples were moderately polluted with benzo[a]pyrene according to China's environmental quality standard for surface water.The two highest concentrations of PAHs and PAEs occurred in samples from Taihu Lake,Wuxi City and the western section of Yangchenghu Lake.Potential sources of pollution at S7 were petroleum combustion and the plastics industry,and at Yangchenghu Lake were petroleum combustion and domestic waste.Pollution in samples from the Beijing-Hangzhou Grand Canal originated from diesel engines.There were no obvious sources of pollution for the other water samples.These results can be used as reference levels for future monitoring programs of pollution from PAHs and PAEs. | Lifei Zhang Liang Dong Lijun Ren Shuangxin Shi Li Zhou Ting Zhang Yeru Huang | 2012 | Journal of Environmental Sciences2012,24,2: | 56 |

| 12 | Circular RNA hsacirc0000745 may serve as a diagnostic marker for gastric cancer显示文摘AIM To determine whether circular RNAs(circ RNAs) are involved in pathological processes of gastric cancer(GC).METHODS Three circ RNAs with differential expression in GC and colorectal cancer were randomly selected for validation by quantitative reverse transcription-polymerase chain reaction(q RT-PCR), using 20 pairs of gastric tissues and normal tissues. Based on the predicted circ RNAmi RNA network, we then focused on hsa_circ_0000745, which was found to be down-regulated in 20 GC tissues compared with normal tissues. The hsa_circ_0000745 levels were further analyzed by q RT-PCR in 60 GC tissues and paired adjacent non-tumor tissues, as well as 60 plasma samples from GC patients and 60 plasma samples from healthy controls. The associations between the levels of hsa_circ_0000745 and the clinicopathological features of GC patients were statistically assessed. A receiver operating characteristic(ROC) curve was used to evaluate the diagnostic value of hsa_circ_0000745 in GC.RESULTS Hsa_circ_0000745 was down-regulated in GC tissues vs non-tumorous tissues(P < 0.001) and in plasma samples from patients with GC vs healthy controls(P < 0.001). The expression level of hsa_circ_0000745 in GC tissues correlated with tumor differentiation, while the expression level in plasma correlated with tumor-nodemetastasis stage. The area under the ROC curve(AUC) of hsa_circ_0000745 in plasma was 0.683, suggesting good diagnostic value. Plasma hsa_circ_0000745 level combined with carcinoembryogenic antigen(CEA) level increased the AUC to 0.775.CONCLUSION Hsa_circ_0000745 plays an important role in GC and its expression level in plasma in combination with CEA level is a promising diagnostic marker for this malignancy. | Mei Huang Yi-Ren He Li-Chuan Liang Qiang Huang Zhi-Qiang Zhu | 2017 | World Journal of Gastroenterology2017,23,34: | 42 |

| 14 | Prealbumin is predictive for postoperative liver insufficiency in patients undergoing liver resection显示文摘AIM:To investigate the risk factors for postoperative liver insufficiency in patients with Child-Pugh class A liver function undergoing liver resection.METHODS:A total of 427 consecutive patients undergoing partial hepatectomy from October 2007 to April 2011 at a single center(Department of Hepatic SurgeryⅠ,Eastern Hepatobiliary Surgery Hospital,Shanghai,China) were included in the study.All the patients had preoperative liver function of Child-Pugh class A and were diagnosed as having primary liver cancer by postoperative histopathology.Surgery was performed by the same team and hepatic resection was carried out by a clamp crushing method.A clamp/unclamp time of 15 min/5 min was adopted for hepatic inflow occlusion.Patients' records of demographic variables,intraoperative parameters,pathological findings and laboratory test results were reviewed.Postoperative liver insufficiency and failure were defined as prolonged hyperbilirubinemia unrelated to biliary obstruction or leak,clinically apparent ascites,prolonged coagulopathy requiring frozen fresh plasma,and/or hepatic encephalopathy.The incidence of postoperative liver insufficiency or liver failure was observed and the attributing risk factors were analyzed.A multivariate analysis was conducted to determine the independent predictive factors.RESULTS:Among the 427 patients,there were 362 males and 65 females,with a mean age of 51.1 ± 10.4 years.Most patients(86.4%) had a background of viral hepatitis and 234(54.8%) patients had liver cirrhosis.Indications for partial hepatectomy included hepatocellular carcinoma(391 patients),intrahepatic cholangiocarcinoma(31 patients) and a combination of both(5 patients).Hepatic resections of ≤ 3 and ≥ 4 liver segments were performed in 358(83.8%) and 69(16.2%) patients,respectively.Seventeen(4.0%) patients developed liver insufficiency after hepatectomy,of whom 10 patients manifested as prolonged hyperbilirubinemia unrelated to biliary obstruction or leak,6 patients had clinically apparent ascites and prolonged coagulopathy,1 patient had hepatic encephalopathy and died on day 21 after surgery.On univariate analysis,age ≥ 60 years and prealbumin < 170 mg/dL were found to be significantly correlated with postoperative liver insufficiency(P = 0.045 and P = 0.009,respectively).There was no statistical difference in postoperative liver insufficiency between patients with or without hepatitis,liver cirrhosis and esophagogastric varices.Intraoperative parameters(type of resection,inflow blood occlusion time,blood loss and blood transfusion) and laboratory test results were not associated with postoperative liver insufficiency either.Age ≥ 60 years and prealbumin < 170 mg/dL were selected on multivariate analysis,and only prealbumin < 170 mg/dL remained predictive(hazard ratio,3.192;95%CI:1.185-8.601,P = 0.022).CONCLUSION:Prealbumin serum level is a predictive factor for postoperative liver insufficiency in patients with liver function of Child-Pugh class A undergoing hepatectomy.Since prealbumin is a good marker of nutritional status,the improved nutritional status may decrease the incidence of liver insufficiency. | Liang Huang Jing Li Jian-Jun Yan Cai-Feng Liu MengChao Wu Yi-Qun Yan | 2012 | World Journal of Gastroenterology2012,18,47: | 36 |
| 15 | Predictors and clinical outcomes for spontaneous rupture of hepatocellular carcinoma显示文摘AIM:To determine the risk factors for hepatocellular carcinoma(HCC) rupture,and report the management and long-term survival results of patients with spontaneous rupture of HCC.METHODS:Among 4209 patients with HCC who were diagnosed at Eastern Hepatobiliary Surgery Hospital from April 2002 to November 2006,200(4.8%) patients with ruptured HCC(case group) were studied retrospectively in term of their clinical characteristics and prognostic factors.The one-stage therapeutic approach to manage ruptured HCC consisted of initial management by conservative treatment,transarterial embolization(TACE) or hepatic resection.Results of various treatments in the case group were evaluated and compared with the control group(202 patients) without ruptured HCC during the same study period.Continuous data were expressed as mean ± SD or me-dian(range) where appropriate and compared using the unpaired t test.Categorical variables were compared using the Chi-square test with Yates correction or the Fisher exact test where appropriate.The overall survival rate in each group was determined using the Kaplan-Meier method and a log-rank test.RESULTS:Compared with the control group,more patients in the case group had underlying diseases of hypertension(7.5% vs 3.0%,P =0.041) and liver cirrhosis(87.5% vs 56.4%,P < 0.001),tumor size >5 cm(83.0% vs 57.4%,P < 0.001),tumor protrusion from the liver surface(66.0% vs 44.6%,P < 0.001),vascular thrombus(30.5% vs 8.9%,P < 0.001) and extrahepatic invasion(36.5% vs 12.4%,P < 0.001).On multivariate logistic regression analysis,underlying diseases of hypertension(P = 0.002) and liver cirrhosis(P < 0.001),tumor size > 5 cm(P < 0.001),vascular thrombus(P = 0.002) and extrahepatic invasion(P < 0.001) were predictive for spontaneous rupture of HCC.Among the 200 patients with spontaneous rupture of HCC,105 patients underwent hepatic resection,33 received TACE,and 62 were managed with conservative treatment.The median survival time(MST) of all patients with spontaneous rupture of HCC was 6 mo(range,1-72 mo),and the overall survival at 1,3 and 5 years were 32.5%,10% and 4%,respectively.The MST was 12 mo(range,1-72 mo) in the surgical group,4 mo(range,1-30 mo) in the TACE group and 1 mo(range,1-19 mo) in the conservative group.Ninety-eight patients in the control group underwent hepatic resection,and the MST and median diseasefree survival time were 46 mo(range,6-93 mo) and 23 mo(range,3-39 mo) respectively,which were much longer than that of patients with spontaneous rupture of HCC undergoing hepatic resection(P < 0.001).The 1-,3-,and 5-year overall survival rates and the 1-,3-and 5-year disease-free survival rates in patients with ruptured HCC undergoing hepatectomy were 57.1%,19.0% and 7.6%,27.6%,14.3% and 3.8%,respectively,compared with those of 77.1%,59.8% and 41.2%,57.1%,40.6% and 32.9% in 98 patients with-CONCLUSION:Prolonged survival can be achieved in selected patients undergoing one-stage hepatectomy,although the survival results were inferior to those of the patients without ruptured HCC. | Qian Zhu Jing Li Jian-Jun Yan Liang Huang Meng-Chao Wu Yi-Qun Yan | 2012 | World Journal of Gastroenterology2012,18,48: | 40 |

| 17 | Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options显示文摘Objective: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and cystic echinococcosis (CE). In the past years, the Chinese government has been increasing the financial support to control the diseases in this region. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policymakers design appropriate control strategies. Review: Selection criteria for which literature to review were firstly defined. Medline, CNKI (China National Knowledge Infrastructure), and Google Scholar were systematically searched for literature published between January 2000 and July 2011. Significant risk factors found by single factor and/or multiple factors analysis were listed, counted, and summarized. Literature was examined to check the comparability of the data;age and sex specific prevalence with same data structures were merged and used for further analysis. A variety of assumed social, economical, behavioral, and ecological risk factors were studied on the Plateau. Those most at risk were Tibetan herdsmen, the old and female in particular. By analyzing merged comparable data, it was found that females had a significant higher prevalence, and a positive linearity relationship existed between echinococcosis prevalence and increasing age. In terms of behavioral risk factors, playing with dogs was mostly correlated with CE and/or AE prevalence. In terms of hygiene, employing ground water as the drinking water source was significantly correlated with CE and AE prevalence. For definitive hosts, dog related factors were most frequently identified with prevalence of CE or/and AE;fox was a potential risk factor for AE prevalence only. Overgrazing and deforestation were significant for AE prevalence only. Conclusion: Tibetan herdsmen communities were at the highest risk of echinococcosis prevalence and should be the focus of echinococcosis control. Deworming both owned and stray dogs should be a major measure for controlling echinococcosis;treatment of wild definitive hosts should also be considered for AE endemic areas. Health education activities should be in concert with the local people's education backgrounds and languages in order to be able to improve behaviors. Further researches are needed to clarify the importance of wild hosts for AE/CE prevalence, the extent and range of the impacts of ecologic changes (overgrazing and deforestation) on the AE prevalence, and risk factors in Tibet. | Qian Wang Yan Huang Liang Huang Wenjie Yu Wei He Bo Zhong Wei Li Xiangman Zeng Dominique A Vuitton Patrick Giraudoux Philip S Craig Weiping Wu | 2014 | Infectious Diseases of Poverty2014,3,1: | 35 |
| 18 | Does Helicobacter pylori infection play a role in iron deficiency anemia? A meta-analysis显示文摘AIM:To perform a meta-analysis of observational studies and randomized controlled trials(RCTs)on the association between Helicobacter pylori(H.pylori)and iron deficiency anemia(IDA).METHODS:A defined search strategy was used to search Medline,Embase,the Cochrane Library,Clinical Trials,Cochrane Central Register of Controlled Trials,Premedline and Healthstar.Odds ratio(OR)was used to evaluate observational epidemiology studies,and weighted mean difference(WMD)was used to demonstrate the difference between control and intervention groups.RESULTS:Fifteen observational studies and 5 RCTs were identified and used for calculation.The pooled OR for observational studies was 2.22(95%CI:1.52-3.24,P<0.0001).The WMD for hemoglobin(HB) was 4.06 g/L(95%CI:-2.57-10.69,P=0.01),and the WMD for serum ferritin(SF)was 9.47μg/L(95%CI:-0.50-19.43,P<0.0001).Results were heterogeneous for all comparisons.CONCLUSION:This meta-analysis on observational studies suggests an association between H.pylori and IDA.In RCTs,eradication of H.pylori can improve HB and SF levels but not significantly. | Qu, Xin-Hua Huang, Xiao-Lu Xiong, Ping Zhu, Cui-Ying Huang, You-Liang Lu, Lun-Gen Sun, Xu Rong, Lan Zhong, Liang Sun, Da-Yu Lin, Hai Cai, Ming-Ci Chen, Zhi-Wei Hu, Bing Wu, Lian-Ming Jiang, Yi-Bin Yan, Wei-Li | 2010 | World Journal of Gastroenterology2010,16,7: | 34 |

| 20 | Modulatory effects of acupuncture on brain networks in mild cognitive impairment patients显示文摘Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong(EX-HN1), Yintang(EX-HN3), Neiguan(PC6), Taixi(KI3), Fenglong(ST40), and Taichong(LR3), or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment. | Ting-ting Tan Dan Wang Ju-ke Huang Xiao-mei Zhou Xu Yuan Jiu-ping Liang Liang Yin Hong-liang Xie Xin-yan Jia Jiao Shi Fang Wang Hao-bo Yang Shang-jie Chen | 2017 | Neural Regeneration Research2017,12,2: | 32 |
