1Expenditure of hospital care on cancer in China, from 2011 to 2015显示文摘Objective: A solid understanding of levels and trends of spending on cancer is important to evaluate whether our healthcare resources were wisely spent and to prioritize future resources for cancer treatment and prevention.However, studies on economic burden of cancers in China are scant and the results are inconsistent.Methods: The Chinese hospital information database and nearly 350 million inpatient medical record data were used. As the ratios of cancer inpatient payments to total inpatient payments were mainly influenced by the grades and sites of hospitals, the estimates of payments of cancer inpatients in this study were stratified by hospital grades and provinces. Only the payments of cancer inpatients happened in grade 2, grade 3 and specialized cancer hospitals were included in the analyses. The total medical payments of cancers in China were estimated based on the ratios of outpatient payments to inpatient payments in specialized cancer hospitals.Results: From 2011 to 2015, the payments of cancer inpatients in China have increased by 84.1% and the total inpatient payments reached 177.1 billion RMB in 2015, accounting for 4.3% of the total health expenditure in China. Based on the ratio of outpatient payments to inpatient payments, the total payments on cancer treatments in China were estimated to be 221.4 billion RMB in 2015. Among different cancer types, the highest payments were the treatment of trachea, bronchus and lung cancer. The major cancer inpatient payments(67.1% in 2015) spent in grade 3 general hospitals and this ratio increased continually from 2011 to 2015. The expenditure of cancer treatments also varies by region with the major expenditure in the eastern region of China.Conclusions: This study estimated the total payments of cancer treatments in China and analyzed how the money was spent on cancer treatments in the recent 5 years, which would provide information for decision makings on the allocation of resources to service provisioning, prevention strategies, research funding, and assessing whether the economic burden of cancer is affordable to the governments.Yue Cai Ming Xue Wanqing Chen Maogui Hu Zhiwen Miao Lan Lan Rongshou Zheng Qun Meng 2017Chinese Journal of Cancer Research2017,29,3:81
2Effect of phosphorylation of MAPK and Stat3 and expression of c-fos and c-jun proteins on hepatocarcinogenesis and their clinical significance显示文摘AIM To study the effect of phosphorylation ofMAPK and Stat3 and the expression of c-fos andc-jun proteins on hepatocellular carcinogenesisand their clinical significance.METHODS SP immunohistochemistry was usedto detect the expression of p42/44MAPK, p-Stat3,c-fos and c-jun proteins in 55 hepatocellularcarcinomas (HCC) and their surrounding livertissues.RESULTS The positive rates and expressionlevels of p42/44MAPK, p-Stat3, c-fos and c-junproteins in HCCs were significantly higher thanthose in pericarcinomatous liver tissues (PCLT).A positive correlation was observed between theexpression of p42/44MAPK and c-fos proteins, andbetween p-Stat3 and c-jun, but there was nosignificant correlation between p42/44MAPK and p-Stat3 in HCCs and their surrounding livertissues.CONCLUSION The abnormalities of Ras/Rat/MAPK and JAKs/ Stat3 cascade reaction maycontribute to malignant transformation ofhepatocytes. Hepatocytes which are positive forp42/ 44MAPK, c-fos or c-jun proteins may bepotential malignant pre-cancerous cells.Activation of MAPK and Stat3 proteins may be anearly event in hepatocellular carcinogenesis.De Yun Feng Hui Zheng Yi Tan Rui Xue Cheng Department of Pathology, Hunan Medical University, Changsha 410078, Hunan Province, China New England Biolab, MA, USA 2001World Journal of Gastroenterology2001,7,1:75
3Hybrid-augmented intelligence: collaboration and cognition显示文摘人工智能追求的长期目标是使机器能像人一样学习和思考。由于人类面临的许多问题具有不确定性、脆弱性和开放性,任何智能程度的机器都无法完全取代人类,这就需要将人的作用或人的认知模型引入到人工智能系统中,形成混合-增强智能的形态,这种形态是人工智能或机器智能的可行的、重要的成长模式。混合-增强智能可以分为两类基本形式:一类是人在回路的人机协同混合增强智能,另一类是将认知模型嵌入机器学习系统中,形成基于认知计算的混合智能。本文讨论人机协同的混合-增强智能的基本框架,以及基于认知计算的混合-增强智能的基本要素:直觉推理与因果模型、记忆和知识演化;特别论述了直觉推理在复杂问题求解中的作用和基本原理,以及基于记忆与推理的视觉场景理解的认知学习网络;阐述了竞争-对抗式认知学习方法,并讨论了其在自动驾驶方面的应用;最后给出混合-增强智能在相关领域的典型应用。Nan-ning ZHENG Zi-yi LIU Peng-ju REN Yong-qiang MA Shi-tao CHEN Si-yu YU Jian-ru XUE Ba-dong CHEN Fei-yue WANG 2017Frontiers of Information Technology & Electronic Engineering2017,18,2:51
4Optimal operation of electricity, natural gas and heat systems considering integrated demand responses and diversified storage devices显示文摘In recent years, the increasing penetration level of renewable generation and combined heat and power(CHP) technology in power systems is leading to significant changes in energy production and consumption patterns. As a result, the integrated planning and optimal operation of a multi-carrier energy(MCE) system have aroused widespread concern for reasonable utilization of multiple energy resources and efficient accommodation of renewable energy sources. In this context, an integrated demand response(IDR) scheme is designed to coordinate the operation of power to gas(P2 G) devices, heat pumps,diversified storage devices and flexible loads within an extended modeling framework of energy hubs. Subsequently, the optimal dispatch of interconnected electricity,natural gas and heat systems is implemented considering the interactions among multiple energy carriers by utilizing the bi-level optimization method. Finally, the proposed method is demonstrated with a 4-bus multi-energy systemand a larger test case comprised of a revised IEEE 118-bus power system and a 20-bus Belgian natural gas system.Linna NI Weijia LIU Fushuan WEN Yusheng XUE Zhaoyang DONG Yu ZHENG Rui ZHANG 2018Journal of Modern Power Systems and Clean Energy2018,6,3:30
5Spatial Characteristics of Extreme Rainfall over China with Hourly through 24-Hour Accumulation Periods Based on National-Level Hourly Rain Gauge Data显示文摘Hourly rainfall measurements of 1919 national-level meteorological stations from 1981 through 2012 are used to document,for the first time,the climatology of extreme rainfall in hourly through 24-h accumulation periods in China. Rainfall amounts for 3-,6-,12- and 24-h periods at each station are constructed through running accumulation from hourly rainfall data that have been screened by proper quality control procedures. For each station and for each accumulation period,the historical maximum is found,and the corresponding 50-year return values are estimated using generalized extreme value theory. Based on the percentiles of the two types of extreme rainfall values among all the stations,standard thresholds separating Grade I,Grade II and Grade III extreme rainfall are established,which roughly correspond to the 70th and 90th percentiles for each of the accumulation periods. The spatial characteristics of the two types of extreme rainfall are then examined for different accumulation periods. The spatial distributions of extreme rainfall in hourly through 6-h periods are more similar than those of 12- and 24-h periods. Grade III rainfall is mostly found over South China,the western Sichuan Basin,along the southern and eastern coastlines,and in the large river basins and plains. There are similar numbers of stations with Grade III extreme hourly rainfall north and south of 30°N,but the percentage increases to about 70% south of 30°N as the accumulation period increases to 24 hours,reflecting richer moisture and more prolonged rain events in southern China. Potential applications of the extreme rainfall climatology and classification standards are suggested at the end.Yongguang ZHENG Ming XUE Bo LI Jiong CHEN Zuyu TAO 2016Advances in Atmospheric Sciences2016,33,11:28

SGC-7901 cells. Eightday after treatment with various concentrations of c9, tl1-CLA mentioned above, the inhibition rates were 5.92 % ,20.15 % ,75.61% and 82.44 % ,respectively and inhibitory effeotof c9, tll-CLA on DNA synthesis (except for 25 tmol/L,24h) showed significantly less 3H-TdR incorporation than thatin the negative controls (P < 0. 05 and P < 0. 01).Immunocytochemical staining demonstrated that SGC-7901cells preincubated in media supplemented with different c9,tl1-CLA concentrations at various times significantlydecreased the expressions of PCNA (the expression rateswere7.2-3.0 %,24 h and 9.1-0.9 % at 48 h, respectively),Cyclin A (l1.0-2.3 %, 24 h and 8.5-0.5 % ,48 h), B1 (4.8-1.8% at 24 h and 5.5-0.6 % at 48 h)and D1 (3.6-1.4 % at 24 hand 3.7 %-0 at 48 h) as compared with those in the negativecontrols(the expressions of PCNA, Cyclin A, B1 and D1were 6.5 % at 24h and 9.0 % at 48 h, 4.2% at 24h and5.1% at 48 h, 9.5 % at 24h and 6.0 % at 48 h,respectively)(P< 0.01), whereas the expressions of p16ink4a and p21clp/waf1,cyclin-dependent kinases inhibltors(CDKI), were increased.CONCLUSION: The cell growth and proliferation of SGC-7901cell is inhibited by c9, tll-CLA via blocking the cell cycle,with reduced expressions of cyclin A, B1 and D1 andenhanced expressions of CDKI( p16ink4a and p21cip/waf1).Jia-Ren Liu Bai-Xiang Li Bing-Qing Chen Ying-ben Xue Yan-Mei Yang Yu-Mei Zheng,Department of Toxicological Health,Public Health College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Xiao-Hui Han ICU of Cardiological Surgery,The Second Hospital,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Rui-Hai Liu,Food Science and Toxicology,Department of Food Science,Cornell University,Ithaca,NY 14853-7201,USA 2002World Journal of Gastroenterology2002,8,2:26
9Unconjugated bilirubin alleviates experimental ulcerative colitis by regulating intestinal barrier function and immune inflammation显示文摘BACKGROUND Unconjugated bilirubin(UCB) is generally considered toxic but has gained recent prominence for its anti-inflammatory properties. However, the effects of it on the interaction between intestinal flora and organisms and how it influences immune responses remain unresolved.AIM To investigate the role of UCB in intestinal barrier function and immune inflammation in mice with dextran-sulfate-sodium-induced colitis.METHODS Acute colitis was induced by 3%(w/v) dextran sulfate sodium salt in drinking water for 6 d followed by untreated water for 2 d. Concurrently, mice with colitis were administered 0.2 mL UCB(400 μmol/L) by intra-gastric gavage for 7 d.Disease activity index(DAI) was monitored daily. Mice were sacrificed at the end of the experiment. The length of the colon and weight of the spleen were recorded. Serum level of D-lactate, intestinal digestive proteases activity, and changes to the gut flora were analyzed. In addition, colonic specimens were analyzed by histology and for expression of inflammatory markers and proteins.RESULTS Mice treated with UCB had significantly relieved severity of colitis, including lower DAI, longer colon length, and lower spleen weight(colon length: 4.92 ±0.09 cm vs 3.9 ± 0.15 cm; spleen weight: 0.33 ± 0.04 vs 0.74 ± 0.04, P < 0.001). UCB administration inactivated digestive proteases(chymotrypsin: 18.70 ± 0.69 U/g vs44.81 ± 8.60 U/g; trypsin: 1.52 ± 0.23 U/g vs 9.05 ± 1.77 U/g, P < 0.01), increased expression of tight junction(0.99 ± 0.05 vs 0.57 ± 0.03, P < 0.001), decreased serum level of D-lactate(31.76 ± 3.37 μmol/L vs 54.25 ± 1.45 μmol/L, P < 0.001), and lowered histopathological score(4 ± 0.57 vs 7 ± 0.57, P < 0.001) and activity of myeloperoxidase(46.79 ± 2.57 U/g vs 110.32 ± 19.19 U/g, P < 0.001). UCB also regulated the intestinal microbiota, inhibited expression of tumor necrosis factor(TNF) α and interleukin 1β(TNF-α: 52.61 ± 7.81 pg/mg vs 105.04 ± 11.92 pg/mg,interleukin 1β: 13.43 ± 1.68 vs 32.41 ± 4.62 pg/mg, P < 0.001), decreased expression of Toll-like receptor 4(0.61 ± 0.09 vs 1.07 ± 0.03, P < 0.001) and myeloid differentiation primary response gene 88(0.73 ± 0.08 vs 1.01 ± 0.07, P <0.05), and increased expression of TNF-receptor-associated factor 6(0.79 ± 0.02 vs0.43 ± 0.09 P < 0.05) and inhibitor of kappa B α(0.93 ± 0.07 vs 0.72 ± 0.07, P < 0.05)in the colon.CONCLUSION UCB can protect intestinal barrier function, regulate normal intestinal homeostasis, and suppress inflammation via the Toll-like receptor 4/nuclear factor-κB signaling pathway.Jia-Dong Zheng Yan He Heng-Yuan Yu Yuan-Li Liu Yi-Xuan Ge Xue-Ting Li Xue Li Yan Wang Meng-Ru Guo Yi-Lin Qu Xiao-Fa Qin Ming-Shan Jiang Xiu-Hong Wang 2019World Journal of Gastroenterology2019,25,15:26
10Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
11Variation of head and facial morphological characteristics with increased age of Han in Southern China显示文摘We investigated 13940 (6735 male, 7250 female) adult head and facial physical attributes from 19 different Han ethnic groups in 10 southern-China provinces, and calculated 12 head and facial indexes. Indexes were used to analyze the variation of head and facial morphological characteristics with increased age. Results showed that as age increases: (1) Head breadth, minimum frontal breadth, face breadth, interocular breadth, external biocular breadth, lip height, lip thickness, head circumference, auricular height, length-breadth head index, length-height head index, and lip-index values decline significantly in a linear fashion. (2) Nose breadth, mouth breadth, morphological facial height, upper-lip height, physiognomic ear length, physiognomic ear breadth, visor skin-fold, and vertical head-facial index values significantly increase in a linear fashion.LI YongLan ZHENG LianBin YU KeLi LU ShunHua ZHANG XingHua LI YuLing WANG Yang XUE Hong DENG Wei 2013Chinese Science Bulletin2013,58,4:20
12Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics.Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan 2020Cell Research2020,30,8:19
13Effect of notoginsenoside R1 on hepatic microcirculation disturbance induced by gut ischemia and reperfusion显示文摘AIM: To assess the effect of notoginsenoside R1 on hepatic microcirculatory disturbance induced by gut ischemia/reperfusion (I/R) in mice.METHODS: The superior mesenteric artery (SMA) of C57/BL mice was ligated for 15 min to induce gut ischemia followed by 30-min reperfusion. In another set of experiments, R1 was continuously infused (10 mg/kg per hour) from 10 min before I/R until the end of the investigation to study the influence of R1 on hepatic microcirculatory disturbance induced by gut I/R. Hepatic microcirculation was observed by inverted microscopy, and the vascular diameter, red blood cell (RBC) velocity and sinusoid perfusion were estimated. Leukocyte rolling and adhesion were observed under a laser confocal microscope. Thirty and 60 min after reperfusion, lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate transaminase (AST) in peripheral blood were determined. The expression of adhesion molecules CD11b/CD18 in neutrophils and tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in plasma were evaluated by flow cytometry. E-selectin and intercellular adhesion molecule-1 (ICAM-1) in hepatic tissue were examined by immunofluorescence. RESULTS: After gut I/R, the diameters of terminal portal venules and central veins, RBC velocity and the number of perfused sinusoids were decreased, while the leukocyte rolling and adhesion, the expression of E-selectin in hepatic vessels and CD18 in neutrophils, IL-6, MCP-1, LDH, ALT and AST were increased. R1 treatment attenuated these alterations except for IL-6 and MCP-1.CONCLUSION: R1 prevents I/R-induced hepatic microcirculation disturbance and hepatocyte injury. The effect of R1 is related to its inhibition of leukocyte rolling and adhesion by inhibiting the expression of E-selectin in endothelium and CD18 in neutrophils.Wei-Xing Chen Fang Wang, Yu-Ying Liu, Qing-Jiang Zeng, Kai Sun, Xin Xue, Xiang Li, Ji-Ying Yang, Li-Hua An,Bai-He Hu, Jin-Hui Yang, Chuan-She Wang, Zhi-Xin Li, Lian-Yi Liu, Yan Li, Jun Zheng, Fu-Long Liao, Dong Han,Jing-Yu Fan, Jing-Yan Han Fang Wang Yu-Ying Liu Qing-Jiang Zeng Kai Sun Xin Xue Xiang Li Ji-Ying Yang Li-Hua An Bai-He Hu Jin-Hui Yang Chuan-She Wang Zhi-Xin Li Lian-Yi Liu Yan Li Jun Zheng Fu-Long Liao Dong Han Jing-Yu Fan Jing-Yan Han 2008World Journal of Gastroenterology2008,14,1:17
14Rapid improvement of PM2.5 pollution and associated health benefits in China during 2013–2017显示文摘Exposure to fine particulate matter(PM2.5)is known to harm public health.In China,after implementation of aggressive emissions control measures under the Action Plan of Air Pollution Prevention and Control(2013-2017),air quality has significantly improved.In this work,we investigated changes in PM2.5 exposure and the associated health impacts in China for the period 2013-2017.We used an optimal estimator of PM2.5 combining in-situ observations,satellite measurements,and simulations from a chemical transport model to derive the spatial and temporal variations in PM2.5 exposure,and then used welldeveloped exposure-response functions to estimate the premature deaths attributable to PM2.5 exposure.We found that national population-weighed annual mean PM2.5 concentrations decreased from 67.4μgm-3 in 2013 to 45.5μgm-3 in 2017(32%reduction).This rapid decrease in PM2.5 pollution led to a 14%reduction in premature deaths due to long-term exposure.We estimated that,during 2013-2017,the premature deaths attributable to long-term PM2.5 exposure decreased from 1.2 million(95%CI:1.0,1.3;fraction of total mortality:13%)in 2013 to 1.0 million(95%CI:0.9,1.2;10%)in 2017.Despite the rapid decrease in annual mean PM2.5 concentrations,health benefits associated with reduced long-term exposure were limited,because for many cities,the PM2.5 levels remain at the portion where the exposure-response function is less steeper than that at the lowconcentration end.We also found that the deaths associated with acute exposure decreased by 61%during 2013-2017 due to rapid reduction in the number of heavily polluted days.Our results confirm that clean air policies in China have mitigated the air pollution crisis;however,continuous emissions reduction efforts are required to protect citizens from air pollution.Tao XUE Jun LIU Qiang ZHANG Guannan GENG Yixuan ZHENG Dan TONG Zhu LIU Dabo GUAN Yu BO Tong ZHU Kebin HE Jiming HAO 2019Science China Earth Sciences2019,62,12:17
15A highly alkaline-stable metal oxide@metal-organic framework composite for high-performance electrochemical energy storage显示文摘Most metal-organic frameworks(MOFs) hardly maintain their physical and chemical properties after exposure to alkaline aqueous solutions,thus precluding their use as potential electrode materials for electrochemical energy storage devices.Here,we present the design and synthesis of a highly alkaline-stable metal oxide@MOF composite,Co3O4 nanocube@Co-MOF(Co3O4@Co-MOF),via a controllable and facile one-pot hydrothermal method under highly alkaline conditions.The obtained composite possesses exceptional alkaline stability,retaining its original structure in 3.0 M KOH for at least 15 days.Benefitting from the exceptional alkaline stability,unique structure,and larger surface area,the Co3O4@Co-MOF composite shows a specific capacitance as high as 1020 F g-1 at 0.5 A g-1 and a high cycling stability with only 3.3% decay after 5000 cycles at 5 A g-1.The as-constructed solid-state flexible device exhibits a maximum energy density of 21.6 mWh cm-3.Shasha Zheng Qing Li Huaiguo Xue Huan Pang Qiang Xu 2020National Science Review2020,7,2:16

18Dermoscopy in China: current status and future prospective显示文摘Objective: Dermoscopy is a useful technique for improving the diagnostic accuracy of various types of skin disorders. In China, dermoscopy has been widely accepted, and domestic researchers have made tremendous progress in the field of dermoscopy. The main purpose of this review is to summarize the current status of dermoscopy in China and identify its future directions. Data sources: Articles included in this review were obtained by searching the following databases: Wanfang, China National Knowledge Infrastructure, PubMed, and the Web of Science. We focused on research published before 2019 with keywords including dermoscopy, dermoscopic, dermoscope and trichoscopy. Study selection: A total of 50 studies were selected. Of these studies, 20 studies were in Chinese and 30 in English, research samples of all the studies were collected from Chinese populations. Results: Since 2000, more than 380 articles about dermoscopy have been published in domestic or foreign journals. Dermoscopy can improve the diagnostic accuracy of neoplastic diseases, evaluating the therapeutic effect of treatment, and determining the treatment endpoint, and it can also assist in the differential diagnosis of inflammatory diseases and in the assessment of the severity of the disease. In addition, researches about the applications of dermoscopy during surgical treatment have been published. Training courses aiming to improve the diagnostic ability of dermatologists, either face-to-face or online, have been offered. The Chinese Skin Image Database, launched in 2017 as a work platform for dermatologists, has promoted the development of dermoscopy in China. Computer-aided diagnostic systems based on the Chinese population are ready for use. In the future, cooperation, resource sharing, talent development, image management, and computer-aided diagnosis will be important directions for the development of dermoscopy in China. Conclusion: Dermoscopy has been widely used and developed in China, however, it still needs to address more challenges in the future.Xue Shen Rui-Xing Yu Chang-Bing Shen Cheng-Xu Li Yan Jing Ya-Jie Zheng Zi-Yi Wang Ke Xue Feng Xu Jian-Bin Yu Ru-Song Meng Yong Cui 2019Chinese Medical Journal2019,,17:15
19Induction of apoptosis by artemisinin relieving the severity of inflammation in caerulein-induced acute pancreatitis显示文摘AIM:To observe the apoptosis and oncosis of pancreatic acinar cells and secondary inflammatory reaction in pancreatic tissue from rats with acute pancreatitis(AP),and the influences of artemisinin on them.METHODS:AP was induced by 4 intraperitoneal injections of caerulein at 1 h intervals.To induce apoptosis,solution of artemisinin(50 mg/kg)was given intraperitoneally 1,12,24 and 36 h after the last caerulein injection.Histological examination of impairment of pancreatic tissue and detection of serum amylase were performed to evaluate the severity of acute pancreatitis.Apoptosis and oncosis were detected with acridine orange(AO)and ethylene dibromide(EB)staining.Caspase-3 and myeloperoxidase(MPO)activity were measured by colorimetric assay.Nuclear factor-kappa B(NF-κB)activation was detected by flow cytometry.Macrophage inflammatory protein-1α(MIP-1α)protein was measured by Western blot.Interleukin-1β(IL-1β)mRNA was detected by RT-PCR.RESULTS:Addition of artemisinin increased the number of apoptotic cells(11.7% ± 1.4% vs 6.3% ± 0.7%,P < 0.05),while reduced the number of oncotic cells(13.0% ± 2.4% vs 17.5% ± 2.2%,P < 0.05).The activity of caspase-3 speeded up(1.52 ± 0.21 vs 1.03 ± 0.08,P < 0.05),the pancreas pathological impairment was relieved(3.0 ± 0.5 vs 4.0 ± 0.5,P < 0.05)and the level of serum amylase decreased(5642 ± 721 U/dL vs 7821 ± 653 U/dL,P < 0.05).The activation of NF-κB(29% ± 4.1% vs 42% ± 5.8%),MIP-1α protein(3.7 ± 0.5 vs 5.8 ± 0.7),MPO(0.52 ± 0.06 U/g vs 0.68 ± 0.09 U/g),IL-1β mRNA(1.7 ± 0.3 vs 2.4 ± 0.4)in the apoptosis inducing group was obviously decreased(P < 0.05).CONCLUSION:Inducing apoptosis can relieve pathological impairment and inflammatory reaction in AP rats.Ming Zhao Dong-Bo Xue Biao Zheng Wei-Hui Zhang Shang-Ha Pan Bei Sun 2007World Journal of Gastroenterology2007,13,42:14
20Characteristics of Settings and Etiologic Agents of Foodborne Disease Outbreaks—China,2020显示文摘Introduction:Foodborne diseases are a growing public health problem and have caused a large burden of disease in China.This study analyzed epidemiological characteristics of foodborne diseases in China in 2020 to provide a scientific basis for prevention and control measures.Methods:Data were collected from 30 of 31 provincial-level administrative divisions(PLADs)in the mainland of China,excluding Xizang(Tibet)Autonomous Region,via the National Foodborne Disease Outbreaks Surveillance System・The number and proportion of outbreaks,illnesses,hospitalizations,deaths by setting,pathogen-food category pairs and etiology were calculated.Results:In 2020,7,073 foodborne disease outbreaks were reported,resulting in 37,454 illnesses and 143 deaths.Among the identified pathogens,microbial pathogens were the most common confirmed etiology,accounting for 41.7%of illnesses.Poisonous mushrooms caused the largest proportion of outbreaks(58.0%)and deaths(57.6%).For venues where foodborne disease outbreaks occur,household had the highest number of outbreaks(4,140)and deaths(128),and catering service locations caused the largest proportion of illnesses(59.9%).Outbreaks occurring between June and September accounted for 62.8%of total outbreaks.Conclusions:Foodborne disease outbreaks mainly occurred in households・Microbial pathogens remained the top cause of outbreak-associated illnesses.Poisonous mushrooms were ranked the top cause of deaths in private homes in China.The supervision and management of food safety and health education should be strengthened to reduce the burden of foodborne diseases・Publicity should be increased to reduce the incidence of mushroom poisonings in families,and supervision and management of food should be strengthened to reduce microbial contamination.Hongqiu Li Weiwei Li Yue Dai Yuyan Jiang Junhua Liang Santao Wang Maoqiang Zhuang Zheng Huang Lizi Xu Bo Xue Jikai Liu Haihong Han Sara M.Pires Ping Fu Yunchang Guo 2021China CDC weekly2021,3,42:14
