| 4 | Histological Subtypes of Lung Cancer in Chinese Males from 2000 to 2012显示文摘Objective To characterize the histological and epidemiological features of male lung cancer patients in China. Methods The demographic and histological information about male lung cancer patients identified from 2000-01-01 to 2012-12-31,was collected from the Cancer Hospital of the Chinese Academy of Medical Sciences. Relative frequencies(RF) were estimated for major histological subtypes and compared according to the years of diagnosis and birth. Results The RF of adenocarcinoma(ADC) increased from 21.96% to 43.36% and the RF of squamous cell carcinoma(SCC) decreased from 39.11% to 32.23% from 2000 to 2012 in the 15 427 male lung cancer patients included in this study(Z=17.909,P<0.0001; Z=-6.117,P<0.0001). The RF of ADC increased from 28.72% in 2000-2004,36.88% in 2005-2008 to 48.61% in 2009-2012 in patients born after 1960. The age-adjusted RF of ADC in 2007-2012 increased consistently in all the investigated areas. Conclusion The increased RF of ADC in male lung cancer patients highlights the need for further investigation of the etiologic factors of these tumors. Smoke-free policies rather than modifying tobacco products should be enforced. | ZOU Xiao Nong LIN Dong Mei WAN Xia CHAO Ann FENG Qin Fu DAI Zhen YANG Gong Huan LV Ning | 2014 | Biomedical and Environmental Sciences2014，27，1： | 19 |
| 5 | Preliminary results of environmental monitoring of the natural gas hydrate production test in the South China Sea显示文摘Natural gas hydrate (NGH)is considered as one of the new clean energy sources of the 21st century with the highest potential.The environmental issues of NGH production have attracted the close attention of scientists in various countries.From May 10 to July 9,2017,the first offshore NGH production test in the South China Sea (SCS)was conducted by the China Geological Survey.In addition,environmental security has also been effectively guaranteed via a comprehensive environmental monitoring system built during the NGH production test.The monitoring system considered sea-surface atmosphere methane and carbon dioxide concentrations,dissolved methane in the sea water column,and the seafloor physical oceanography and marine chemistry environment.The whole process was monitored via multiple means, in multiple layers,in all domains,and in real time.After the production test,an environmental investigation was promptly conducted to evaluate the environmental impact of the NGH production test. The monitoring results showed that the dissolved methane concentration in seawater and the near-seabed environment characteristics after the test were consistent with the background values,indicating that the NGH production test did not cause environmental problems such as methane leakage. | Jian-liang Ye Xu-wen Qin Hai-jun Qiu Qian-yong Liang Yi-fei Dong Jian-gong Wei Hai-long Lu Jing-an Lu Yao-hong Shi Chao Zhong Zhen Xia | 2018 | China Geology2018，1，2： | 19 |
| 6 | Efficacy and safety of salmeterol/fluticasone compared with montelukast alone (or add-on therapy to fluticasone) in the treatment of bronchial asthma in children and adolescents: a systematic review and meta-analysis显示文摘Background:Despite the recommendation of inhaled corticosteroids(ICSs)plus long-acting beta 2-agonist(LABA)and leukotriene receptor antagonist(LTRA)or ICS/LTRA as stepwise approaches in asthmatic children,there is a lack of published systematic review comparing the efficacy and safety of the two therapies in children and adolescents aged 4 to 18 years.This study aimed to compare the safety and efficacy of salmeterol/fluticasone(SFC)vs.montelukast(MON),or combination of montelukast and fluticasone(MFC)in children and adolescents aged 4 to 18 years with bronchial asthma.Methods:A systematic search was conducted in MEDLINE,EMBASE,the Cochrane Library,China BioMedical Literature Database,Chinese National Knowledge Infrastructure,VIP Database for Chinese Technical Periodical,and Wanfang for randomized controlled trials(RCTs)published from inception to May 24,2021.Interventions are as follows:SFC vs.MON,or combination of MFC,with no limitation of dosage or duration.Primary and secondary outcome measures were as follows:the primary outcome of interest was the risk of asthma exacerbation.Secondary outcomes included risk of hospitalization,pulmonary function,asthma control level,quality of life,and adverse events(AEs).A random-effects(I^(2)≥50%)or fixed-effects model(I^(2)<50%)was used to calculate pooled effect estimates,comparing the outcomes between the intervention and control groups where feasible.Results:Of the 1006 articles identified,21 studies met the inclusion criteria with 2643 individuals;two were at low risk of bias.As no primary outcomes were similar after an identical treatment duration in the included studies,meta-analysis could not be performed.However,more studies favored SFC,instead of MON,owing to a lower risk of asthma exacerbation in the SFC group.As for secondary outcome,SFC showed a significant improvement of peak expiratory flow(PEF)%pred after 4 weeks compared with MFC(mean difference[MD]:5.45;95%confidence interval[CI]:1.57-9.34;I^(2)=95%;P=0.006).As for asthma control level,SFC also showed a higher full-controlled level(risk ratio[RR]:1.51;95%CI:1.24-1.85;I^(2)=0;P<0.001)and higher childhood asthma control test score after 4 weeks of treatment(MD:2.30;95%CI:1.39-3.21;I^(2)=72%;P<0.001)compared with MFC.Conclusions:SFC may be more effective than MFC for the treatment of asthma in children and adolescents,especially in improving asthma control level.However,there is insufficient evidence to make firm conclusive statements on the use of SFC or MON in children and adolescents aged 4 to 18 years with asthma.Further research is needed,particularly a combination of good-quality long-term prospective studies and well-designed RCTs.PROSPERO registration number:CRD42019133156. | Xiao-Jian Zhou Zhen Qin Jiao Lu Jian-Guo Hong | 2021 | Chinese Medical Journal2021，，24： | 16 |
| 7 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021，3，21： | 16 |
| 8 | Impact of Heat Wave in 2005 on Mortality in Guangzhou, China显示文摘Objective To assess the impact of the heat wave in 2005 on mortality among the residents in Guangzhou and to identify susceptible subpopulations in Guangzhou, China. Methods The data of daily number of deaths and meteorological measures from 2003 to 2006 in Guangzhou were used in this study. Heat wave was defined as ≥7 consecutive days with daily maximum temperature above 35.0 ℃ and daily mean temperature above the 97th percentile during the study period. The excess deaths and rate ratio (RR) of mortality in the case period compared with the reference period in the same summer were calculated. Results During the study period, only one heat wave in 2005 was identified and the total number of excess deaths was 145 with an average of 12 deaths per day. The effect of the heat wave on non-accidental mortality (RR=1.23, 95% CI: 1.11-1.37) was found with statistically significant difference. Also, greater effects were observed for cardiovascular mortality (RR=1.34, 95% CI: 1.13-1.59) and respiratory mortality (RR=1.31, 95% CI: 1.02-1.69). Females, the elderly and people with lower socioeconomic status were at significantly higher risk of heat wave-associatedmortality. Conclusion The 2005 heat wave had a substantial impact on mortality among the residents in Guangzhou, particularly among some susceptible subpopulations. The findings from the present study may provide scientific evidences to develop relevant public health policies and prevention measures aimed at reduction of preventable mortality from heat waves. | YANG Jun LIU Hua Zhang OU Chun Quan LIN Guo Zhen DING Yan ZHOU Qin SHEN Ji Chuan CHEN Ping Yan | 2013 | Biomedical and Environmental Sciences2013，26，8： | 16 |
| 9 | 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 | Picroside Ⅱ down-regulates matrix metalloproteinase-9 expression following cerebral ischemia/reperfusion injury in rats显示文摘Studies have shown that Picroside II attenuates inflammatory reactions following brain ischemia through the inhibition of the TLR-4-NF-κB signal transduction pathway,and ameliorates cerebral edema through the reduction of aquaporin-4 expression.Matrix metalloproteinase-9 (MMP-9),located downstream of the TLR-4-NF-κB signal transduction pathway,can degrade the neurovascular matrix,damage the blood-brain barrier to induce cerebral edema,and directly result in neuronal apoptosis and brain injury.Therefore,the present study further observed MMP-9 expression in the brain tissues of rats with cerebral ischemia/reperfusion injury following Picroside II treatment.Results demonstrated that Picroside II significantly reduced MMP-9 expression in ischemic brain tissues,as well as neuronal apoptosis and brain infarct volume,suggesting Picroside II exhibits neuroprotection by down-regulating MMP-9 expression and inhibiting cell apoptosis. | Xiang Li Xinying Xu Zhen Li Yunliang Guo Qin Li Xiaodan Li Zhen Zhou | 2010 | Neural Regeneration Research2010，5，18： | 13 |
| 16 | Prevalence and characteristics of MAFLD in Chinese adults aged 40 years or older:A community-based study显示文摘Background: Nonalcoholic fatty liver disease(NAFLD) was recently proposed to be renamed metabolic dysfunction-associated fatty liver disease(MAFLD) with the diagnostic criteria revised. We investigated the similarities and differences in the prevalence and clinical characteristics of MAFLD and NAFLD in Chinese adults. Methods: A cross-sectional study of 9980 Chinese individuals aged 40 years or older was performed between 2011 and 2012 using randomized, stratifed cluster sampling in Shanghai, China. A detailed questionnaire and the results of abdominal ultrasonography, a standardized 2-h 75-g oral glucose tolerance test and blood biochemical examinations were collected. Results: A total of 9927 subjects were included in this study. The prevalence of MAFLD(40.3%) was significantly higher than that of NAFLD(36.9%)( P < 0.05). MAFLD was highly prevalent in type 2 diabetes mellitus(T2DM)(53.8%), impaired fasting glucose(35.7%) and impaired glucose tolerance(40.9%). High risk of advanced fbrosis based on fbrosis-4 was highly prevalent(14.7%) in lean MAFLD with T2DM. Among 9927 subjects, 3481(35.1%) fulflled the diagnostic criteria for MAFLD and NAFLD(MAFLD + NAFLD +), 521(5.2%) MAFLD + NAFLD-, and 181(1.8%) MAFLD-NAFLD +. The MAFLD + NAFLD-group had more signifcant metabolic disorders than those in the MAFLD + NAFLD + group(all P < 0.05). Among MAFLD-NAFLD + subjects, 82.9% had metabolic disorders. Conclusions: The new defnition of MAFLD may better reflect the pathogenesis related to metabolism. Future research should focus on studying the natural history, pathogenesis and treatment effectivity of the overlap and non-overlap of NAFLD and MAFLD subjects. | Jing Zeng Li Qin Qian Jin Rui-Xu Yang Guang Ning Qing Su Zhen Yang Jian-Gao Fan | 2022 | Hepatobiliary & Pancreatic Diseases International2022，21，2： | 13 |
| 17 | Seroepidemiological Investigation of Lyme Disease and Human Granulocytic Anaplasmosis among People Living in Forest Areas of Eight Provinces in China显示文摘Objective Lyme disease and Human granulocytic anaplasmosis are tick‐borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum. Methods Forest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA). Results Seroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks. Conclusion We conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces. | HAO Qin GENG Zhen HOU Xue Xia TIAN Zhen YANG Xiu Jun JIANG Wei Jia SHI Yan ZHAN Zhi Fei LI Guo Hua YU De Shan WANG Hua Yong XU Jian Guo WAN Kang Lin | 2013 | Biomedical and Environmental Sciences2013，26，3： | 13 |

| 19 | Fabrication and properties of foam geopolymer using circulating fluidized bed combustion fly ash显示文摘In recent years,circulating fluidized bed combustion fly ash(CFA) is used as a raw material for geopolymer synthesis.Hydrogen peroxide was employed as a foaming agent to prepare CFA-based foam geopolymer.The particle distribution,mineral composition,and chemical composition of CFA were examined firstly.Geopolymerization products were characterized by mechanical testing,scanning electron microscopy(SEM),X-ray diffraction(XRD),and X-ray fluorescence(XRF).The CFA-based foam geopolymer was successfully fabricated with different contents of hydrogen peroxide and exhibited uncompleted alkali reaction and reasonable strength with relative low atomic ratios of Si/Al and Si/Na.Type-C CFA in this research could be recycled as an alternative source material for geopolymer production. | Ze Liu Ning-ning Shao Dong-min Wang Jun-feng Qin Tian-yong Huang Wei Song Mu-xi Lin Jin-sha Yuan Zhen Wang | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，1： | 11 |
| 20 | Qingnaoyizhi decoction suppresses the formation of glial fibrillary acidic protein-positive cells in cultured neural stem cells by inhibiting the Janus kinase 2/signal transducer and activator of transcription 3 signaling pathway显示文摘OBJECTIVE: Inactivation of the Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3) signaling axis plays a crucial role in determining the fate of neural stem cells(NSCs).Qingnaoyizhi decoction(QNYZD) has been used for the treatment of vascular dementia and has shown to improve synaptic remodeling. The aim of this study was to evaluate the effect of cerebrospinal fluid(CSF) containing QNYZD(CSF-QNYZD) on the differentiation of cultured NSCs and the involvement of the JAK2/STAT3 pathway.METHODS: The protein expression levels of glial fibrillary acidic protein(GFAP), tubulin, drosophila mothers against decapentaplegic protein(SMAD-1), STAT3, and phosphorylated-STAT3 were detected by western immunoblot analysis in the groups: control, CSF, JAK/STAT inhibitor(AG490),CSF-QNYZD, and CSF-XDZ(CSF-Xidezhen). The differentiation of NSCs was determined by immunofluorescence staining. The proliferation of NSCs was measured using the Cell Counting Kit-8 proliferation assay.RESULTS: Compared with the control group,CSF-QNYZD and AG490 significantly increased the number and expression of tubulin-positive cells, reduced the number and expression of GFAP-positive cells, and down-regulated the expression of p-STAT3. However, CSF-QNYZD also decreased the expression of SMAD-1 and STAT3.CONCLUSION: Enhanced neuronal differentiation may be associated with the down-regulation of glial differentiation instead of promoting proliferationin treated NSCs. Furthermore, QNYZD may play a direct role in suppressing the formation of GFAP-positive cells and enhancing neuronal differentiation by inhibiting JAK2/STAT3 activation. Overall, these results provide insights into the possible mechanism underlying QNYZD-mediated neurogenesis. | Wu Yanqing Jing Zhiwei Qin Xiude Zhou Zhen Wang Kai Song Wanshan Wang Xueyan Hou Mengmeng Zhang Yulian Kang Liyuan | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 11 |
