| 1 | Prevalence of minimal hepatic encephalopathy and quality of life evaluations in hospitalized cirrhotic patients in China显示文摘AIM:To investigate the prevalence of minimal hepatic encephalopathy(MHE)and to assess corresponding health-related quality of life(HRQoL)in hospitalized cirrhotic patients in China.METHODS:This multi-center cross-sectional study included 16 teaching hospitals,which were members of 'Hepatobiliary Cooperation Group,Society of Gastroenterology,Chinese Medical Association',from different areas of China carried out between June and October in 2011.All the eligible hospitalized cirrhotic patients(n = 538)were required to complete triplicate number connection tests combined with one digit symbol test for diagnosing MHE.Patients' clinical examination data were complemented by a modified questionnaire assessing HRQoL.Written informed consent was obtained from each patient.RESULTS:Male was predominant(68.6%)in 519 patients who met the criteria of the study,with a mean age of 49.17 ± 11.02 years.The most common cause of liver cirrhosis was chronic hepatitis B(55.9%).The prevalence of MHE was 39.9% and varied by ChildPugh-Classification score(CPC-A:24.8%,CPC-B:39.4% and CPC-C:56.1%,P < 0.01).MHE(P < 0.01)and higher CPC scores(P < 0.01)were associated with a high HRQoL scores(reflecting poorer quality of life).The prevalence of MHE was proportionate to CPC(P = 0.01)and high quality of life scores(P = 0.01).CONCLUSION:Hospitalized cirrhotic patients have a high prevalence of MHE that is proportionate to the degree of liver function and HRQoL impairment. | Ji-Yao Wang Ning-Ping Zhang Bao-Rong Chi Yu-Qing Mi Li-Na Meng Ying-Di Liu Jiang-Bin Wang Hai-Xing Jiang Jin-Hui Yang Yun Xu Xiao Li Jian-Ming Xu Guo Zhang Xin-Min Zhou Yu-Zheng Zhuge De-An Tian Jin Ye Yu-Lan Liu | 2013 | World Journal of Gastroenterology2013，19，30： | 64 |
| 2 | Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level. | XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan | 2009 | Chinese Science Bulletin2009，54，17： | 40 |
| 3 | Linking atmospheric pollution to cryospheric change in the Third Pole region: current progress and future prospects显示文摘The Tibetan Plateau and its surroundings are known as the Third Pole(TP). This region is noted for its high rates of glacier melt and the associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic and cryospheric changes through their effects on solar radiation and the albedos of snow and ice surfaces; moreover, the behavior and fates within the cryosphere and environmental impacts of environmental pollutants are topics of increasing concern. In this review, we introduce a coordinated monitoring and research framework and network to link atmospheric pollution and cryospheric changes(APCC) within the TP region. We then provide an up-to-date summary of progress and achievements related to the APCC research framework, including aspects of atmospheric pollution’s composition and concentration, spatial and temporal variations, trans-boundary transport pathways and mechanisms, and effects on the warming of atmosphere and changing in Indian monsoon, as well as melting of glacier and snow cover. We highlight that exogenous air pollutants can enter into the TP’s environments and cause great impacts on regional climatic and environmental changes. At last, we propose future research priorities and map out an extended program at the global scale. The ongoing monitoring activities and research facilitate comprehensive studies of atmosphere–cryosphere interactions, represent one of China’s key research expeditions to the TP and the polar regions and contribute to the global perspective of earth system science. | Shichang Kang Qianggong Zhang Yun Qian Zhenming Ji Chaoliu Li Zhiyuan Cong Yulan Zhang Junming Guo Wentao Du Jie Huang Qinglong You Arnico K.Panday Maheswar Rupakheti Deliang Chen Orjan Gustafsson Mark H.Thiemens Dahe Qin | 2019 | National Science Review2019，6，4： | 35 |

| 6 | Synthesis and evaluation of an oil-soluble viscosity reducer for heavy oil显示文摘To reduce the viscosity of highly-viscous oil of the Tahe oilfield (Xinjiang,China),an oilsoluble polybasic copolymer viscosity reducer for heavy oil was synthesized using the orthogonal method.The optimum reaction conditions are obtained as follows:under the protection of nitrogen,a reaction time of 9 h,monomer mole ratio of reaction materials of 3:2:2 (The monomers are 2-propenoic acid,docosyl ester,maleic anhydride and styrene,respectively),initiator amount of 0.8% (mass percent of the sum of all the monomers) and reaction temperature of 80 oC.This synthesized viscosity reducer is more effective than commercial viscosity reducers.The rate of viscosity reduction reached 95.5% at 50 oC.Infrared spectra (IR) and interfacial tensions of heavy oil with and without viscosity reducer were investigated to understand the viscosity reduction mechanism.When viscosity reducer is added,the molecules of the viscosity reducer are inserted amongst the molecules of crude oil,altering the original intermolecular structure of crude oil and weakening its ability to form hydrogen bonds with hydroxyl or carboxyl groups,so the viscosity of crude oil is reduced.Field tests of the newly developed oil-soluble viscosity reducer was carried out in the Tahe Oilfield,and the results showed that 44.5% less light oil was needed to dilute the heavy oil to achieve the needed viscosity. | Guo Jixiang Wang Heyi Chen Chaogang Chen Yun Xie Xiaohai | 2010 | Petroleum Science2010，7，4： | 24 |

| 9 | Effects of dietary yeast β-glucan on nutrient digestibility and serum profiles in pre-ruminant Holstein calves显示文摘This study aimed to investigate the effects of dietary supplementation of yeast β-glucan on the nutrient digestibility and serum profiles in pre-ruminant Holstein calves. Forty-two neonatal Holstein calves((39.6±4.2) kg) were randomly allotted to six groups, and each was offered one of the following diets: a basal diet(control) or the basal diet supplemented with 25, 50, 75, 100 or 200 mg of yeast β-glucan kg–1 feed(dry matter basis). The basal diet consisted of a milk replacer and a starter feed. The trial lasted for 56 d. Two digestibility trials were conducted from d 14 to 20 and from d 42 to 48. Blood samples were collected on d 0, 14, 28 and 42 for serum profile analyses. On d 56, three calves from each group were slaughtered, and intestinal samples were collected to assess the villous height, crypt depth and mucosal thickness. Although feed intake was not affected by dietary treatment(P>0.05), the average daily gain(ADG) and gain-to-feed ratios were higher(P<0.05) for the calves fed 75 mg of yeast β-glucan kg–1 feed than those in the other groups. The supplementation of yeast β-glucan at 75 mg kg–1 feed increased the apparent digestibility of dry matter(DM), crude protein(CP), ether extract(EE), and phosphorus(P)(P<0.05) and the ratio of intestinal villous height to crypt depth(V/C)(P<0.05) when compared with the control group. No effects of yeast β-glucan on the serum concentrations of total protein(TP), albumin(ALB), serum urea nitrogen(SUN) and glucose(GLU) were observed(P>0.05). Compared with the control group, supplementation of yeast β-glucan decreased(P<0.05) the serum concentrations of triglycerides(TG) and total cholesterol(TC). The serum concentration of immunoglobulin G(Ig G) and immunoglobulin M(Ig M) increased quadratically(P<0.05), whereas the serum concentration of immunoglobulin A(Ig A) was unaffected by dietary treatments(P>0.05). The supplementation of yeast β-glucan stimulated the enzymatic activity of alkaline phosphatase(ALP)(P<0.05) compared with the control group. The lysozyme(LYZ) concentration increased quadratically(P<0.05) with increasing yeast β-glucan levels. The results suggested that dietary supplementation of yeast β-glucan at 75 mg kg–1 feed improved nutrient digestibility, enhanced immunity by increasing the immunoglobulin concentration and stimulating ALP, and exerted no adverse effects on metabolism in pre-ruminant calves. | MA Tao TU Yan ZHANG Nai-feng GUO Jiang-peng DENG Kai-dong ZHOU Yi YUN Qiang DIAO Qi-yu | 2015 | Journal of Integrative Agriculture2015，14，4： | 23 |
| 10 | Establishment and application of an artificial intelligence diagnosis system for pancreatic cancer with a faster region-based convolutional neural network显示文摘Background:Early diagnosis and accurate staging are important to improve the cure rate and prognosis for pancreatic cancer.This study was performed to develop an automatic and accurate imaging processing technique system,allowing this system to read computed tomography(CT)images correctly and make diagnosis of pancreatic cancer faster.Methods:The establishment of the artificial intelligence(AI)system for pancreatic cancer diagnosis based on sequential contrastenhanced CT images were composed of two processes:training and verification.During training process,our study used all 4385 CT images from 238 pancreatic cancer patients in the database as the training data set.Additionally,we used VGG16,which was pretrained in ImageNet and contained 13 convolutional layers and three fully connected layers,to initialize the feature extraction network.In the verification experiment,we used sequential clinical CT images from 238 pancreatic cancer patients as our experimental data and input these data into the faster region-based convolution network(Faster R-CNN)model that had completed training.Totally,1699 images from 100 pancreatic cancer patients were included for clinical verification.Results:A total of 338 patients with pancreatic cancer were included in the study.The clinical characteristics(sex,age,tumor location,differentiation grade,and tumor-node-metastasis stage)between the two training and verification groups were insignificant.The mean average precision was 0.7664,indicating a good training ejffect of the Faster R-CNN.Sequential contrastenhanced CT images of 100 pancreatic cancer patients were used for clinical verification.The area under the receiver operating characteristic curve calculated according to the trapezoidal rule was 0.9632.It took approximately 0.2 s for the Faster R-CNN AI to automatically process one CT image,which is much faster than the time required for diagnosis by an imaging specialist.Conclusions:Faster R-CNN AI is an effective and objective method with high accuracy for the diagnosis of pancreatic cancer. | Shang-Long Liu Shuo Li Yu-Ting Guo Yun-Peng Zhou Zheng-Dong Zhang Shuai Li Yun Lu | 2019 | Chinese Medical Journal2019，，23： | 23 |
| 11 | Mesenchymal stem cells transduced by PLEGFP-N1 retroviral vector maintain their biological features and differentiation显示文摘Background Enhanced green fluorescent protein(EGFP) has been an important reporter gene for gene therapy. Human mesenchymal stem cells (hMSCs) are ideal target cells in cell transplantation and tissue engineering. We investigated their biological characteristics and differentiation mediated b y PLEGFP-N1 retroviral transduction. Methods hMSCs were isolated from human bone marrow by density g radient fractionation and adherence to plastic flasks. Individual colonies were selected and cultured in tissue dishes. Packaging cells PT67 were transfected by PLEGFP-N1 retroviral vector , and hMSCs were transduced by viral supernatant infection. Meanwhile, hMSCs-EGFP were identified by immune phenotypes and whe ther it could differentiate into osteoblasts or adipocytes under conditioned med ia was investigated. Results The rate of stably transduced hMSCs-EGFP was up to 96% after being screened by G418. hMSCs-EGFP exhibited fibroblast-like morpholog ical features. Flow cytometric analyses showed that hMSCs-EGFP were positive f or CD 73, CD 105, CD 166, CD 90 and CD 44, but negative for CD 34 and CD 45. In addition, it could functionally be induced i nto osteocytes or adipocytes under conditioned media. These biological features of hMSCs-EGFP were consistent with those of hMSCs. Conclusions hMSCs transduced by PLEGFP-N1 retroviral vector ca n be used in vivo securely because they can maintain their biological charac teristics and differentiation. It is a simple and reliable way to trace the ch anges of hMSCs in vivo by EGFP during cell transplantation and gene therapy . | HE Xu LI Yu-lin WANG Xin-rui GUO Xin NIU Yun | 2005 | Chinese Medical Journal2005，，20： | 20 |

| 13 | Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups. | YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng | 2016 | Biomedical and Environmental Sciences2016，29，3： | 18 |
| 14 | Report on Childhood Obesity in China (10): Association of Sleep Duration with Obesity显示文摘Objectives To explore the association of sleep duration with obesity among children in urban areas of China.Methods A total of 6 576 children(3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China.A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level.The height,weight,waist circumference(WC) and percentage of body fat(%BF,as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures.The information on demography,lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.Results The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age(P<0.05).The sleep duration was negatively associated with body mass index(BMI) and WC in both boys and girls after adjustment for confounders(β value-0.23 and-0.82 for boys,-0.24 and-0.91 for girls,respectively,P<0.01).However,no significant association of sleep duration with %BF was found.Children who slept less than 9.0 h per night had a higher risk for overweight and obesity(OR=1.29,95% CI:1.01,1.64) and abdominal obesity(OR=1.38,95% CI:1.04,1.83) as compared with those who slept for 10.0-10.9 h.Conclusions Short sleep duration is associated with obesity.It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life. | MENG Li Ping LIUAi Ling HU Xiao Qi ZHANG Qian DU Song Ming FANG Hong Yun MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 16 |

| 16 | Long-term results of paclitaxel plus cisplatin with concurrent radiotherapy for loco-regional esophageal squamous cell carcinoma显示文摘AIM To evaluate the long-term effectiveness and late toxicities of paclitaxel(PTX) plus cisplatin(DDP) with concurrent radiotherapy for locally advanced esophageal squamous cancer.METHODS Between 2008 and 2011, 76 patients were enrolled in a phase Ⅱ study on the treatment of loco-regionally advanced esophageal cancer with radiotherapy(68.4 Gy/44 fractions or 61.2 Gy/34 fractions) combined with 4-cycle chemotherapy consisting of DDP(25 mg/m^2 per day for 3 d) and PTX(175 mg/m^2 for 3 h). The primary endpoints were overall survival and progression-free survival, and the secondary endpoints were toxicity and the treatment failure pattern.RESULTS A total of 76 patients were enrolled in this study, of whom 63.2% finished the whole regimen. The 5-year survival rates for the per-protocol population and intent-to-treat population were 25.4% and 26.4%, respectively, and the median survival rates were 23.7 mo and 28.5 mo, respectively. Grade 3 or 4 late toxicity was observed in only one patient(heart failure). In log-rank analysis, the pretreatment stage(stage Ⅱ + Ⅲ: 36.1 mo vs stage Ⅳ: 14.9 mo) and the completed cycle(1-3 cycles: 16.1 mo vs 4 cycles: 35.5 mo) were significant prognostic factors(P = 0.037 < 0.05 and P = 0.013 < 0.05).CONCLUSION Radiotherapy combined with chemotherapy consisting of PTX and DDP is a safe and effective definitive treatment for loco-regionally advanced esophageal squamous cancer. | Han-Ting Zhu Da-Shan Ai Hua-Rong Tang Harun Badakhshi Jian-Hong Fan Jia-Ying Deng Jun-Hua Zhang Yun Chen Zhen Zhang Yi Xia Xiao-Mao Guo Guo-Liang Jiang Kuai-Le Zhao | 2017 | World Journal of Gastroenterology2017，23，3： | 14 |

| 20 | Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency. | Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen | 2018 | Science Bulletin2018，63，24： | 12 |
