| 2 | Relationship between Cognition Function and Hippocampus Structure after Long-term Microwave Exposure显示文摘Objective To analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.Methods Experiments were performed on 184 male Wistar rats(three exposure groups and a sham group).Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5,5,and 10 mW/cm2.Learning and memory abilities were assessed by Morris water maze.High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus.Hippocampal structures were observed by histopathological analysis.Results Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d,14 d,and 1 m in all three microwave exposure groups.Neurotransmitter concentrations of four amino acids(glutamate,aspartic acid,glycine,and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group.There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups.Further,mitochondria became swollen and cristae were disordered.The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.Conclusion These data suggest that the hippocampus can be injured by long-term microwave exposure,which might result in impairment of cognitive function due to neurotransmitter disruption. | ZHAO Li PENG Rui Yun WANG Shui Ming WANG Li Feng GAO Ya Bing DONG Ji LI Xiang SU Zhen Tao | 2012 | Biomedical and Environmental Sciences2012，25，2： | 27 |

| 5 | p53 upregulated by HIF-la promotes hypoxiainduced G2/M arrest and renal fibrosis in vitro and in vivo显示文摘Hypoxia plays an important role in the genesis and progression of renal fibrosis.The underlying mechanisms, however, have not been sufficiently elucidated. We examined the role of p53 in hypoxia-induced renal fibrosis in cell culture (human and rat renal tubular epithelial cells) and a mouse unilateral ureteral obstruction (UUO) model. Cell cycle of tubular cells was determined by flow cytometry, and the expression of profibrogenic factors was determined by RT-PCR, immunohistochemistry, and western blotting. Chromatin immunoprecipitation and luciferase reporter experiments were performed to explore the effect of HIF-lα on p53 expression. We showed that, in hypoxic tubular cells, p53 upregulation suppressed the expression of CDK1 and cyclins Bl and DI, leading to cell cycle (G2/M) arrest (or delay) and higher expression of TGF-β, CTGF, collagens, and fibronectin. p53 suppression by siRNA or by a specific p53 inhibitor (PIF-α) triggered opposite effects preventing the G2/M arrest and profibrotic changes. In vivo experiments in the UUO model revealed similar antifibrotic results following intraperitoneal administration of PIF-α(2.2 mg/kg). Using gain-of-function, loss-of-function, and luciferase assays, we further identified an HRE3 region on the p53 promoter as the HIF-lα-binding site. The HIF-la-HRE3 binding resulted in a sharp transcriptional activation of p53. Collectively, we show the presence of a hypoxia-activated, p53-responsive profibrogenic pathway in the kidney. During hypoxia, p53 upregulation induced by HIF-la suppresses cell cycle progression, leading to the accumulation of G2/M cells, and activates profibrotic TGF-β and CTGF-mediated signaling pathways, causing extracellular matrix production and renal fibrosis. | Limin Liu Peng Zhang Ming Bai Lijie He Lei Zhang Ting Liu Zhen Yang Menglu Duan Minna Liu Baojian Liu Rui Du Qi Qian Shiren Sun | 2019 | Journal of Molecular Cell Biology2019，11，5： | 18 |
| 6 | Classification of histological severity of Helicobacter pylori-associated gastritis by confocal laser endomicroscopy显示文摘AIM: To classify the histological severity of Helicobacter pylori (H. pylori) infection-associated gastritis by confocal laser endomicroscopy (CLE). METHODS: Patients with upper gastrointestinal symptoms or individuals who were screened for gastric cancer were enrolled in this study. Histological severity of H. pylori infection-associated gastritis was graded according to the established CLE criteria. Diagnostic value of CLE for histo-logical gastritis was investigated and compared with that of white light endoscopy (WLE). Targeted biopsies from the sites observed by CLE were performed. RESULTS: A total of 118 consecutive patients with H. pylori infection-associated gastritis were enrolled in this study. Receiver operating characteristic curve analysis showedthat the sensitivity and specifi city of CLE were 82.9% and 90.9% for the diagnosis of H. pylori infection, 94.6% and 97.4% for predicting gastric normal mucosa, 98.5% and 94.6% for predicting histological active inflammation, 92.9% and 95.2% for predicting glan-dular atrophy, 98.6% and 100% for diagnosing intes-tinal metaplasia, respectively. Post-CLE image analysis showed that goblet cells and absorptive cells were the two most common parameters on the CLE-diagnosed intestinal metaplasia (IM) images (P < 0.001). More his-tological lesions of the stomach could be found by CLE than by WLE (P < 0.001). CONCLUSION: CLE can accurately show the histological severity of H. pylori infection-associated gastritis. Mapping IM by CLE has a rather good diagnostic accuracy. | Peng Wang Rui Ji Tao Yu Xiu-Li Zuo Chang-Qing Li Zhen Li Yan-Qing Li Cheng-Jun Zhou | 2010 | World Journal of Gastroenterology2010，16，41： | 17 |

| 10 | Novel adaptive neural control of flexible air-breathing hypersonic vehicles based on sliding mode differentiator显示文摘A novel adaptive neural control strategy is exploited for the longitudinal dynamics of a generic flexible air-breathing hypersonic vehicle(FAHV).By utilizing functional decomposition method, the dynamics of FAHV is decomposed into the velocity subsystem and the altitude subsystem.For each subsystem, only one neural network is employed for the unknown function approximation.To further reduce the computational burden, minimal-learning parameter(MLP)technology is used to estimate the norm of ideal weight vectors rather than their elements.By introducing sliding mode differentiator(SMD) to estimate the newly defined variables, there is no need for the strict-feedback form and virtual controller.Hence the developed control law is considerably simpler than the ones derived from back-stepping scheme.Finally, simulation studies are made to illustrate the effectiveness of the proposed control approach in spite of the flexible effects, system uncertainties and varying disturbances. | Bu Xiangwei Wu Xiaoyan Ma Zhen Zhang Rui | 2015 | Chinese Journal of Aeronautics2015，28，4： | 11 |
| 11 | A bioinspired path planning approach for mobile robots based on improved sparrow search algorithm显示文摘In this paper,a bioinspired path planning approach for mobile robots is proposed.The approach is based on the sparrow search algorithm,which is an intelligent optimization algorithm inspired by the group wisdom,foraging,and anti-predation behaviors of sparrows.To obtain high-quality paths and fast convergence,an improved sparrow search algorithm is proposed with three new strategies.First,a linear path strategy is proposed,which can transform the polyline in the corner of the path into a smooth line,to enable the robot to reach the goal faster.Then,a new neighborhood search strategy is used to improve the fitness value of the global optimal individual,and a new position update function is used to speed up the convergence.Finally,a new multi-index comprehensive evaluation method is designed to evaluate these algorithms.Experimental results show that the proposed algorithm has a shorter path and faster convergence than other state-ofthe-art studies. | Zhen Zhang Rui He Kuo Yang | 2022 | Advances in Manufacturing2022，10，1： | 9 |

| 14 | Estimating survival benefit of adjuvant therapy based on a Bayesian network prediction model in curatively resected advanced gallbladder adenocarcinoma显示文摘BACKGROUND The factors affecting the prognosis and role of adjuvant therapy in advanced gallbladder carcinoma(GBC)after curative resection remain unclear.AIM To provide a survival prediction model to patients with GBC as well as to identify the role of adjuvant therapy.METHODS Patients with curatively resected advanced gallbladder adenocarcinoma(T3 and T4)were selected from the Surveillance,Epidemiology,and End Results database between 2004 and 2015.A survival prediction model based on Bayesian network(BN)was constructed using the tree-augmented na?ve Bayes algorithm,and composite importance measures were applied to rank the influence of factors on survival.The dataset was divided into a training dataset to establish the BN model and a testing dataset to test the model randomly at a ratio of 7:3.The confusion matrix and receiver operating characteristic curve were used to evaluate the model accuracy.RESULTS A total of 818 patients met the inclusion criteria.The median survival time was 9.0 mo.The accuracy of BN model was 69.67%,and the area under the curve value for the testing dataset was 77.72%.Adjuvant radiation,adjuvant chemotherapy(CTx),T stage,scope of regional lymph node surgery,and radiation sequence were ranked as the top five prognostic factors.A survival prediction table was established based on T stage,N stage,adjuvant radiotherapy(XRT),and CTx.The distribution of the survival time(>9.0 mo)was affected by different treatments with the order of adjuvant chemoradiotherapy(cXRT)>adjuvant radiation>adjuvant chemotherapy>surgery alone.For patients with node-positive disease,the larger benefit predicted by the model is adjuvant chemoradiotherapy.The survival analysis showed that there was a significant difference among the different adjuvant therapy groups(log rank,surgery alone vs CTx,P<0.001;surgery alone vs XRT,P=0.014;surgery alone vs cXRT,P<0.001).CONCLUSION The BN-based survival prediction model can be used as a decision-making support tool for advanced GBC patients.Adjuvant chemoradiotherapy is expected to improve the survival significantly for patients with node-positive disease. | Zhi-Min Geng Zhi-Qiang Cai Zhen Zhang Zhao-Hui Tang Feng Xue Chen Chen Dong Zhang Qi Li Rui Zhang Wen-Zhi Li Lin Wang Shu-Bin Si | 2019 | World Journal of Gastroenterology2019，25，37： | 9 |
| 15 | Petrogenesis and Ore Genesis of the Late Yanshanian Granites and Associated Porphyry-Skarn W-Mo Deposits from the Yunkai Area of South China: Evidence from the Zircon U-Pb Ages, Hf Isotopes and Sulfide S-Fe Isotopes显示文摘There are a wide range of magmatism and mineralization in the Yunkai area of South China during the Late Yanshanian Period, including the newly discovered Michang, Youmapo, Sanchachong and Songwang porphyry-skarn W-Mo deposits. In this study, we obtained zircon U-Pb ages of the ore-bearing biotite granites and their mafic enclaves from 88± 1 to 110± 1 Ma. Zircons from the granites show Hf isotopic compositions with negative ?Hf(t) values of-5.9 to-0.6 and calculated Hf model ages(TDM2) of 1.5–1.2 Ga; indicating that the Middle Proterozoic crustal materials may have provided an important source for the magmatic rocks in this district during the Late Yanshanian Period, whereas zircons from the mafic enclaves show positive ?Hf(t) values of 1.3 to 10.1 with younger Hf model ages(TDM2) of 0.5–1.1 Ga, suggesting a mantle component may have involved in the granitic magma generation. Sulfur isotope study of the sulfide minerals from the W-Mo deposits show a narrow δ34 S distribution with most data ranging from-4.2‰ to 5.2‰. In addition, this study reports the first Fe isotopic compositions of pyrite in the W-Mo deposits, which show a uniform distribution range with the values near zero(δ56 Fe=0.16‰–0.58‰, average 0.35‰; δ57 Fe=0.02‰–0.54‰, average 0.48‰). These data indicate that the ore-forming materials may come from the deep-sourced granitic magma, and the mineralizations show a close relationship with the granitic magmatism during the Late Yanshanian Period. Combining with previous results, we suggest that there is a widespread porphyry-skarn W-Mo mineralization in the Yunkai area during the Late Cretaceous(80–110 Ma), which has a close relationship with the Late Yanshanian magmatism that may have formed during the rollback of the subducted Pacific Plate. | Xinyu Wang Zhen Yang Nengsong Chen Rui Liu | 2018 | Journal of Earth Science2018，29，4： | 8 |
| 16 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |
| 17 | Serum LDH level may predict outcome of chronic lymphocytic leukemia patients with a 17p deletion: a retrospective analysis of prognostic factors in China显示文摘Objective:This study aims to evaluate the natural history of patients with chronic lymphocytic leukemia(CLL)and a 17p deletion(17p-)and identify the predictive factors within this subgroup.Methods:The sample of patients with CLL were analyzed by fluorescence in situ hybridization for deletions in chromosome bands 11q22,13q14 and 17p13;trisomy of bands 12q13;and translocation involving band 14q32.The data from 456 patients with or without a 17p-were retrospectively collected and analyzed.Results:The overall response rate(ORR)in patients with a 17p-was 56.9%,and patients with a high percentage of 17p-(defined as more than 25%of cells harbouring a 17p-)had a lower ORR.The median overall survival(OS)in patients with a 17p-was 78.0 months,which was significantly shorter than the OS in patients without this genetic abnormality(median 162.0 months,P<0.001).Within the subgroup with a 17p-,the progression-free survival was significantly shorter in patients at Binet stage B-C and patients with elevated lactate dehydrogenase(LDH),B symptoms,unmutated IGHV and a high percentage of 17p-.Conclusions:These results indicated that patients with a 17p-CLL have a variable prognosis that might be predicted using simple clinical and laboratory characteristics. | Heng Li Wenjie Xiong Huimin Liu Shuhua Yi Zhen Yu Wei Liu Rui Lyu Tingyu Wang Dehui Zou Zengjun Li Lugui Qiu | 2017 | Chinese Journal of Cancer Research2017，29，2： | 6 |
| 18 | Propofol vs midazolam plus fentanyl for upper gastrointestinal endomicroscopy:A randomized trial显示文摘AIM:To compare the endomicroscopic image quality of integrated confocal laser endomicroscopy(iCLE)and sedation efficacy of propofolvs midazolam plus fentanyl(M/F).METHODS:Consecutive outpatients undergoing iCLE were prospectively recruited and randomized to the propofol group(P group)or M/F group.The patient,performing endoscopist and endoscopic assistant were blinded to the randomization.The quality of endomicro-scopic images and anesthetic efficacy outcomes were blindly evaluated after iCLE examination.RESULTS:There were significantly more good quality endomicroscopic images in the propofol group than in the M/F group(72.75%vs 52.89%,P<0.001).The diagnostic accuracy for upper gastrointestinal mucosal lesions using confocal laser endomicroscopy favors the P group,although this did not reach statistical significance.Adverse events and patient assessment were not significantly different for M/F vs propofol except for more frequent intraprocedural recall with M/F.Procedure duration and sedation times were significantly longer in the M/F group,while the scores of endoscopist,anesthetist and assistant assessment were all significantly better in the P group.CONCLUSION:Sedation with propofol might increase the proportion of good quality endomicroscopic images,and may result in improved procedural efficacy and diagnostic accuracy during iCLE examination. | Xiu-Li Zuo Zhen Li Xiao-Ping Liu Chang-Qing Li Rui Ji Peng Wang Cheng-Jun Zhou Han Liu Yan-Qing Li | 2012 | World Journal of Gastroenterology2012，18，15： | 6 |
| 19 | Cetylpyridinium chloride mouth rinses alleviate experimental gingivitis by inhibiting dental plaque maturation显示文摘Oral rinses containing chemotherapeutic agents, such as cetylpyridinium chloride(CPC), can alleviate plaque-induced gingival infections, but how oral microbiota respond to these treatments in human population remains poorly understood. Via a doubleblinded, randomised controlled trial of 91 subjects, the impact of CPC-containing oral rinses on supragingival plaque was investigated in experimental gingivitis, where the subjects, after a 21-day period of dental prophylaxis to achieve healthy gingivae, received either CPC rinses or water for 21 days. Within-subject temporal dynamics of plaque microbiota and symptoms of gingivitis were pro?led via 16 S ribosomal DNA gene pyrosequencing and assessment with the Mazza gingival index.Cetylpyridinium chloride conferred gingival bene?ts, as progression of gingival in?ammation resulting from a lack of dental hygiene was signi?cantly slower in the mouth rinse group than in the water group due to inhibition of 17 gingivitis-enriched bacterial genera. Tracking of plaque α and β diversity revealed that CPC treatment prevents acquisition of new taxa that would otherwise accumulate but maintains the original biodiversity of healthy plaques. Furthermore, CPC rinses reduced the size, local connectivity and microbiota-wide connectivity of the bacterial correlation network, particularly for nodes representing gingivitisenriched taxa. The ?ndings of this study provide mechanistic insights into the impact of oral rinses on the progression and maturation of dental plaque in the natural human population. | Fei Teng Tao He Shi Huang Cun-Pei Bo Zhen Li Jin-Lan Chang Ji-Quan Liu Duane Charbonneau Jian Xu Rui Li Jun-Qi Ling | 2016 | International Journal of Oral Science2016，8，3： | 6 |
| 20 | A Clustering-tree Topology Control Based on the Energy Forecast for Heterogeneous Wireless Sensor Networks显示文摘How to design an energy-efficient algorithm to maximize the network lifetime in complicated scenarios is a critical problem for heterogeneous wireless sensor networks(HWSN).In this paper, a clustering-tree topology control algorithm based on the energy forecast(CTEF) is proposed for saving energy and ensuring network load balancing, while considering the link quality, packet loss rate, etc. In CTEF, the average energy of the network is accurately predicted per round(the lifetime of the network is denoted by rounds) in terms of the difference between the ideal and actual average residual energy using central limit theorem and normal distribution mechanism, simultaneously. On this basis, cluster heads are selected by cost function(including the energy, link quality and packet loss rate) and their distance.The non-cluster heads are determined to join the cluster through the energy, distance and link quality. Furthermore, several noncluster heads in each cluster are chosen as the relay nodes for transmitting data through multi-hop communication to decrease the load of each cluster-head and prolong the lifetime of the network. The simulation results show the efficiency of CTEF. Compared with low-energy adaptive clustering hierarchy(LEACH), energy dissipation forecast and clustering management(EDFCM) and efficient and dynamic clustering scheme(EDCS)protocols, CTEF has longer network lifetime and receives more data packets at base station. | Zhen Hong Rui Wang Xile Li | 2016 | IEEE/CAA Journal of Automatica Sinica2016，3，1： | 6 |
