| 1 | Effect 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 | 2001 | World Journal of Gastroenterology2001,7,1: | 75 |
| 2 | Optimal 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 | 2018 | Journal of Modern Power Systems and Clean Energy2018,6,3: | 30 |

| 6 | An improved association-mining research for exploring Chinese herbal property theory: based on data of the Shennong's Classic of Materia Medica显示文摘Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine(TCM)researchers.It is a useful tool in understanding and deciphering TCM theories.Aiming for a better understanding of Chinese herbal property theory(CHPT),this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong’s Classic of Materia Medica.The text was firstly annotated and transformed to well-structured multidimensional data.Subsequently,an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters.From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property(qi,flavor and their combinations)and herbal efficacy,two novel fundamental principles underlying CHPT were acquired and further elucidated:(1)the many-to-one mapping of herbal efficacy to herbal property;(2)the nonrandom overlap between the related efficacy of qi and flavor.This work provided an innovative knowledge about CHPT,which would be helpful for its modern research. | Rui Jin Zhi-jian Lin Chun-miao Xue Bing Zhang | 2013 | Journal of Integrative Medicine2013,11,5: | 14 |
| 7 | Test Data Generation for Stateful Network Protocol Fuzzing Using a Rule-Based State Machine显示文摘To improve the efficiency and coverage of stateful network protocol fuzzing, this paper proposes a new method, using a rule-based state machine and a stateful rule tree to guide the generation of fuzz testing data. The method first builds a rule-based state machine model as a formal description of the states of a network protocol.This removes safety paths, to cut down the scale of the state space. Then it uses a stateful rule tree to describe the relationship between states and messages, and then remove useless items from it. According to the message sequence obtained by the analysis of paths using the stateful rule tree and the protocol specification, an abstract data model of test case generation is defined. The fuzz testing data is produced by various generation algorithms through filling data in the fields of the data model. Using the rule-based state machine and the stateful rule tree,the quantity of test data can be reduced. Experimental results indicate that our method can discover the same vulnerabilities as traditional approaches, using less test data, while optimizing test data generation and improving test efficiency. | Rui Ma Daguang Wang Changzhen Hu Wendong Ji Jingfeng Xue | 2016 | Tsinghua Science and Technology2016,21,3: | 13 |
| 8 | Serum Uric Acid is Associated with the Predicted Risk of Prevalent Cardiovascular Disease in a Community-dwelling Population without Diabetes显示文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes. | CHENG Di DU Rui WU Xue Yan LIN Lin PENG Kui MA Li Na XU Yu XU Min CHEN Yu Hong BI Yu Fang WANG Wei Qing DAI Meng LU Jie Li | 2018 | Biomedical and Environmental Sciences2018,31,2: | 13 |
| 9 | Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM. | Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu | 2022 | Military Medical Research2022,9,4: | 13 |
| 10 | DNA chip-based expression profile analysis indicates involvement of the phosphatidylinositol signaling pathway in multiple plant responses to hormone and abiotic treatments显示文摘The phosphatidylinositol (PI) metabolic pathway is considered critical in plant responses to many environmental factors,and previous studies have indicated the involvement of multiple PI-related gene families during cellular responses.Through a detailed analysis of the Arabidopsis thaliana genome,82 polypeptides were identified as being involved in PI signaling. These could be grouped into different families including PI synthases (PIS),PI-phosphate kinases (PIPK),phospholipases (PL),inositol polyphosphate phosphatases (IPPase),inositol polyphosphate kinases (IPK),PI transfer proteins and putative inositol polyphosphate receptors. The presence of more than 10 isoforms of PIPK,PLC,PLD and IPPase suggested that these genes might be differentially expressed during plant cellular responses or growth and development. Accordingly,DNA chip technology was employed to study the expression patterns of various isoforms.In total,79 mRNA clones were amplified and used for DNA chip generation. Expression profile analysis was performed using samples that represented multiple tissues or cellular responses. Tested samples included normal leaf,stem and flower tissues,and leaves from plants treated with various hormones (auxin,cytokinin,gibberellin,abscisic acid and brassinosteroid) or environmental factors (temperature,calcium,sodium,drought,salicylic acid and jasmonic acid).Results showed that many PI pathway-related genes were differentially expressed under these experimental conditions.In particular,the different isoforms of each family were specifically expressed in many cases,suggesting their involvement in tissue specificity and cellular responses to environmental conditions. This work provides a starting point for functional studies of the relevant PI-related proteins and may help shed light onto the role of PI pathways in development and cellular responses. | Wen Hui LIN, Rui YE, Hui MA, Zhi Hong XU, Hong Wei XUE National Laboratory of Plant Molecular Genetics, Institute of Plant Physiology and Ecology, Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences and Partner Group of Max-Planck-Institute of Molecular Plant Physiology (MPI-MP) on 'Plant Molecular Physiology and Signal Transduction', 300 Fenglin Road, 200032 Shanghai, China | 2004 | Cell Research2004,14,1: | 12 |
| 11 | SbHKT1;4, a member of the high‐affinity potassium transporter gene family from Sorghum bicolor, functions to maintain optimal Na^+/K^+ balance under Na^+ stress显示文摘In halophytic plants, the high‐affinity potassium transporter HKT gene family can selectively uptake Kt in the presence of toxic concentrations of Nat. This has so far not been well examined in glycophytic crops. Here, we report the characterization of SbHKT1;4, a member of the HKT gene family from Sorghum bicolor. Upon Nat stress, SbHKT1;4 expression was more strongly upregulated in salt‐tolerant sorghum accession, correlating with a better balanced Nat/ Kt ratio and enhanced plant growth. Heterogeneous expression analyses in mutants of Saccharomyces cerevisiae and Arabidopsis thaliana indicated that overexpressing SbHKT1;4 resulted in hypersensitivity to Nat stress, and such hypersensitivity could be alleviated with the supply of elevated levels of Kt, implicating that SbHKT1;4 may mediate Kt uptake in the presence of excessive Nat. Further electrophysiological evidence demonstrated that SbHKT1;4 could transport Nat and Kt when expressed in Xenopus laevis oocytes. The relevance of the finding that SbHKT1;4 functions to maintain optimal Nat/Kt balance under Nat stress to the breeding of salt‐tolerant glycophytic crops is discussed. | Tian‐Tian Wang Zhi‐Jie Ren Zhi‐Quan Liu Xue Feng Rui‐Qi Guo Bao‐Guo Li Le‐Gong Li Hai‐Chun Jing | 2014 | Journal of Integrative Plant Biology2014,56,3: | 11 |
| 12 | Characteristics and formation mechanism of regional haze episodes in the Pearl River Delta of China显示文摘To investigate the characteristics and the specific mechanism of continuous haze,comprehensive measurements were conducted from 15 October to 19 November in the Atmospheric Environment Monitoring Super-Station in Heshan of Guangdong province.Five haze episodes occurred in October and November 2014 in the Pearl River Delta(PRD)region. The meteorological parameters, gas data, chemical compositions, and optical parameters of the aerosols were obtained. Among these events, the second haze episode,with the highest concentration of PM2.5 of 187.51 μg/m^3, was the most severe. NO^3-was always higher than SO_4^(2-), which indicated that motor vehicles played an important role in the haze, even though the oxidation rate from SO_2 to SO_4^(2-)was faster than that of NOXto NO_3^-. The difference between the hourly averages of Na+and K+during the haze episode and clean days was small, implying that straw combustion and sea salt had no significant effect on the occurrence of haze, and the backward trajectories of the air masses also conformed with this result. The air pollutants were difficult to disperse because of the significant decrease in the planetary boundary layer(PBL) height. Relative humidity played a crucial role in the formation of haze by leading to hygroscopic growth of the diameter of aerosols. | Wenguang Li Xingang Liu Yuanhang Zhang Kang Sun Yusheng Wu Rui Xue Limin Zeng Yu Qu Junling An | 2018 | Journal of Environmental Sciences2018,30,1: | 11 |

| 17 | Baicalin attenuates blood-spinal cord barrier disruption and apoptosis through PI3K/Akt signaling pathway after spinal cord injury显示文摘Baicalin is a natural active ingredient isolated from Scutellariae Radix that can cross the blood-brain barrier and exhibits neuroprotective effects on multiple central nervous system diseases.However,the mechanism behind the neuroprotective effects remains unclear.In this study,rat models of spinal cord injury were established using a modified Allen's impact method and then treated with intraperitoneal injection of Baicalin.The results revealed that Baicalin greatly increased the Basso,Beattie,Bresnahan Locomotor Rating Scale score,reduced blood-spinal cord barrier permeability,decreased the expression of Bax,Caspase-3,and nuclear factorκB,increased the expression of Bcl-2,and reduced neuronal apoptosis and pathological spinal cord injury.SH-SY5 Y cell models of excitotoxicity were established by application of 10 m M glutamate for 12 hours and then treated with 40μM Baicalin for 48 hours to investigate the mechanism of action of Baicalin.The results showed that Baicalin reversed tight junction protein expression tendencies(occludin and ZO-1)and apoptosis-related protein expression(Bax,Bcl-2,Caspase-3,and nuclear factor-κB),and also led to up-regulation of PI3 K and Akt phosphorylation.These effects on Bax,Bcl-2,and Caspase-3 were blocked by pretreatment with the PI3 K inhibitor LY294002.These findings suggest that Baicalin can inhibit bloodspinal cord barrier permeability after spinal cord injury and reduce neuronal apoptosis,possibly by activating the PI3 K/Akt signaling pathway.This study was approved by Animal Ethics Committee of Xi'an Jiaotong University on March 6,2014. | Rui Zhao Xue Wu Xue-Yuan Bi Hao Yang Qian Zhang | 2022 | Neural Regeneration Research2022,17,5: | 9 |
| 18 | Analysis of inpatient payments of breast cancer patients with different medical insurance coverages in China(mainland) in 2011–2015显示文摘Objective: An understanding of the levels and trends of medical cost is made for breast cancer patients with different medical insurance coverages in China(mainland), in an attempt to offer a clue to further control the costs.Methods: The inpatient payments of 9,716,180 breast cancer patients spent in medical institutions of different types and grades during 2011–2015 were collected from the inpatient medical record home page(IMRHP) dataset.The data were then processed with SAS(Version 9.3; SAS Institute, Cary, NC, USA). Indicators like means,increase(decrease) percentages were used to descriptively analyze the average hospitalization expense of each time(AHEET) and its trends of breast cancer patients with different medical insurance coverages treated in medical institutions of different types and grades.Results:In 2011–2015,the AHEET borne by breast cancer patients in China had been constantly increasing.Specifically,the self-pay inpatients had the largest increase,inpatients covered by Urban Employee Basic Medical Insurance(UEBMI)and Urban Resident Basic Medical Insurance(URBMI)were the next,and those covered by New Rural Cooperative Medical System(NRCMS)had the least increase.Breast cancer inpatient treated in public hospitals had quite greater increase and higher expenditure level than those in private hospitals.The AHEET borne by the inpatients in Grade 3 hospitals had greater increase and higher cost than those in Grade 2 hospitals.Conclusions:The inpatient payments of breast cancer patients will be wisely controlled by reducing the number of self-pay inpatients,taking advantage of restriction mechanism of the medical insurances,and promoting healthy competition between private hospitals and public hospitals.The economic burden imposed on the society by breast cancer can be relieved through further control of inpatient payments of UEBMI-and URBMI-covered breast cancer patients and of Grade 3 hospitals. | Rui Li Liang Zhang Jinxia Yang Yue Cai Wanqing Chen Lan Lan Ming Xue Qun Meng | 2017 | Chinese Journal of Cancer Research2017,29,5: | 9 |

| 20 | Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool显示文摘Chang’E-4 landed in the South Pole-Aitken(SPA)basin,providing a unique chance to probe the composition of the lunar interior.Its landing site is located on ejecta strips in Von Karm´an crater that´possibly originate from the neighboring Finsen crater.A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations.In situ spectra of the regolith have peak band positions at 1 and 2μm,similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper,which confirms that the regolith’s composition of the landing area is mostly similar to that of Finsen ejecta.The rock spectrum shows similar band peak positions,but stronger absorptions,suggesting relatively fresh exposure.The rock may consist of 38.1±5.4%low-Ca pyroxene,13.9±5.1%olivine and 48.0±3.1%plagioclase,referred to as olivine-norite.The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle,but representative of the lunar lower crust.Alternatively,the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials.This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool,indicated by the fine to medium-sized texture(<3 mm)of the rock and the SPA-impact melting model[Icarus 2012;220:730–43]. | Honglei Lin Zhiping He Wei Yang Yangting Lin Rui Xu Chi Zhang Meng-Hua Zhu Rui Chang Jinhai Zhang Chunlai Li Hongyu Lin Yang Liu Sheng Gou Yong Wei Sen Hu Changbin Xue Jianfeng Yang Jie Zhong Xiaohui Fu Weixing Wan Yongliao Zou | 2020 | National Science Review2020,7,5: | 9 |
