| 2 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018,63,23: | 54 |
| 3 | Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats. | Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG | 1999 | World Journal of Gastroenterology1999,5,6: | 45 |
| 4 | Combination of Total Astragalus Extract and Total Panax Notoginseng Saponins Strengthened the Protective Effects on Brain Damage through Improving Energy Metabolism and Inhibiting Apoptosis after Cerebral Ischemia-Reperfusion in Mice显示文摘Objective:To explore the effects and molecular mechanisms of the combination between total Astragalus extract(TAE) and total Panax notoginseng saponins(TPNS) against cerebral ischemiareperfusion injury.Methods:C57BL/6 mice were randomly divided into sham-operated group,model group,TAE(110 mg/kg) group,TPNS(115 mg/kg) group,TAE-TPNS combination group and Edaravone(4 mg/kg) group,treated for 4 days,then,cerebral ischemia-reperfusion injury was established by bilateral common carotid artery(CCA) ligation for 20 min followed by reperfusion for 1 and 24 h.Results:TPNS could increase adenosine triphosphate(ATP) level,TAE and TAE-TPNS combination increased ATP,adenosine diphosphate(ADP) contents and Na+-K+-ATPase activity,and the effects of TAE-TPNS combination were stronger than those of TAE or TPNS alone after reperfusion for 1 h.After reperfusion for 24 h,TAE,TPNS and TAE-TPNS combination significantly increased neurocyte survival rate and decreased the apoptosis rate as well as down-regulated the expression of phosphorylated c-June N-terminal kinase1/2(p-JNK1/2),cytochrome C(Cyt C),cysteine aspartic acid-specific protease(Caspase)-9 and Caspase-3.Furthermore,the effects in TAE-TPNS combination were better than those in TAE or TPNS alone.Conclusion:The combination of TAE 110 mg/kg and TPNS 115 mg/kg could strengthen protective effects on cerebral ischemia injury,the mechanism underlying might be related to improving jointly the early energy metabolism,and relieving the delayed apoptosis via inhibiting the mitochondrial apoptosis pathway of JNK signal transduction. | HUANG Xiao-ping TAN Hua CHEN Bei-yang DENG Chang-qing | 2017 | Chinese Journal of Integrative Medicine2017,23,6: | 46 |
| 5 | Programmable time-domain digital-coding metasurface for non-linear harmonic manipulation and new wireless communication systems显示文摘Optical non-linear phenomena are typically observed in natural materials interacting with light at high intensities, and they benefit a diverse range of applications from communication to sensing. However,controlling harmonic conversion with high efficiency and flexibility remains a major issue in modern optical and radio-frequency systems. Here, we introduce a dynamic time-domain digital-coding metasurface that enables efficient manipulation of spectral harmonic distribution. By dynamically modulating the local phase of the surface reflectivity, we achieve accurate control of different harmonics in a highly programmable and dynamic fashion, enabling unusual responses, such as velocity illusion. As a relevant application, we propose and realize a novel architecture for wireless communication systems based on the time-domain digital-coding metasurface, which largely simplifies the architecture of modern communication systems, at the same time yielding excellent performance for real-time signal transmission. The presented work, from new concept to new system, opens new pathways in the application of metamaterials to practical technology. | Jie Zhao Xi Yang Jun Yan Dai Qiang Cheng Xiang Li Ning Hua Qi Jun Chen Ke Guo Dong Bai Shuo Liu Shi Jin Andrea Alù Tie Jun Cui | 2019 | National Science Review2019,6,2: | 46 |
| 6 | Diagnosis and treatment recommendations for pediatric respiratory infection caused by the 2019 novel coronavirus显示文摘Since December 2019,an epidemic caused by novel coronavirus (2019-nCoV) infection has occurred unexpectedly in China.As of 8 pm,31 January 2020,more than 20 pediatric cases have been reported in China.Of these cases,ten patients were identified in Zhejiang Province,with an age of onset ranging from 112 days to 17 years.Following the latest National recommendations for diagnosis and treatment of pneumonia caused by 2019-nCo V (the 4th edition) and current status of clinical practice in Zhejiang Province,recommendations for the diagnosis and treatment of respiratory infection caused by 2019-nCoV for children were drafted by the National Clinical Research Center for Child Health,the National Children's Regional Medical Center,Children's Hospital,Zhejiang University School of Medicine to further standardize the protocol for diagnosis and treatment of respiratory infection in children caused by 2019-nCoV. | Zhi-Min Chen Jun-Fen Fu Qiang Shu Ying-Hu Chen Chun-Zhen Hua Fu-Bang Li Ru Lin Lan-Fang Tang Tian-Lin Wang Wei Wang Ying-Shuo Wang Wei-Ze Xu Zi-Hao Yang Sheng Ye Tian-Ming Yuan Chen-Mei Zhang Yuan-Yuan Zhang | 2020 | World Journal of Pediatrics2020,16,3: | 45 |
| 7 | Does a General Temperature-Dependent Q10 Model of Soil Respiration Exist at Biome and Global Scale?显示文摘Soil respiration (SR) is commonly modeled by a Q10 (an indicator of temperature sensitivity)function in ecosystem models. Q10is usually treated as a constant of 2 in these models, although Q10 value of SR often decreases with increasing temperatures. It remains unclear whether a general temperaturedependent Q10 model of SR exists at biome and global scale. In this paper, we have compiled the long-term Q10 data of 38 SR studies ranging from the Boreal, Temperate, to Tropical/Subtropical biome on four continents.Our analysis indicated that the general temperature-dependent biome Q10 models of SR existed, especially in the Boreal and Temperate biomes. A single-exponential model was better than a simple linear model in fitting the average Q10 values at the biome scale. Average soil temperature is a better predictor of Q10 value than average air temperature in these models, especially in the Boreal biome. Soil temperature alone could explain about 50% of the Q10 variations in both the Boreal and Temperate biome single-exponential Q10 model. Q10 value of SR decreased with increasing soil temperature but at quite different rates among the three biome Q10 models. The k values (Q10 decay rate constants) were 0.09, 0.07, and 0.02/℃ in the Boreal, Temperate, and Tropical/Subtropical biome, respectively, suggesting that Q10 value is the most sensitive to soil temperature change in the Boreal biome, the second in the Temperate biome, and the least sensitive in the Tropical/Subtropical biome. This also indirectly confirms that acclimation of SR in many soil warming experiments probably occurs. The k value in the 'global' single-exponential Q10 model which combined both the Boreal and Temperate biome data set was 0.08/℃. However, the global general temperature-dependent Q10model developed using the data sets of the three biomes is not adequate for predicting Q10 values of SR globally.The existence of the general temperature-dependent Q10 models of SR in the Boreal and Temperate biome has important implications for modeling SR, especially in the Boreal biome. More detail model runs are needed to exactly evaluate the impact of using a fixed Q10 vs a temperature-dependent Q10 on SR estimate in ecosystem models (e.g., TEM, Biome-BGC, and PnET). | Hua CHEN Han-Qin TIAN | 2005 | Journal of Integrative Plant Biology2005,47,11: | 36 |
| 8 | Regional assessment of cadmium pollution in agricultural lands and the potential health risk related to intensive mining activities: A case study in Chenzhou City, China显示文摘The purpose of this study was to assess the extent of cadmium (Cd) contamination in agricultural soil and its potential risk for people. Soils, rice, and vegetables from Chenzhou City, Southern China were sampled and analyzed. In the surface soils, the 95% confidence interval for the mean concentration of Cd varied between 2.72 and 4.83 mg/kg (P < 0.05) in the survey, with a geometric mean concentration of 1.45 mg/kg. Based on the GIS map, two hot spot areas of Cd in agricultural soils with high Cd concentrations were identified to be located around the Shizhuyuan, Jinshiling, and Yaogangxian mines, and the Baoshan and Huangshaping mines, in the center of the city. About 60% of the total investigated area, where the agricultural soil Cd concentration is above 1 mg/kg, is distributed in a central belt across the region. The critical distances, at which the soil Cd concentration were increased by the mining activities, from the mines of the soils were 23 km for the Baoshan mine, 46 km for the Huangshaping mine, and 63 km for the Shizhuyuan mine, respectively. These are distances calculated from models. The Cd concentrations in rice samples ranged from 0.01 to 4.43 mg/kg and the mean dietary Cd intake from rice for an adult was 191 μg/d. Results of risk indexes showed that soil Cd concentrations possessed risks to local residents whose intake of Cd from rice and vegetables grown in soils in the vicinity of the mine was 596 μg/d. | ZHAI Limei LIAO Xiaoyong CHEN Tongbin YAN Xiulan XIE Hua WU Bin WANG Lixia | 2008 | Journal of Environmental Sciences2008,20,6: | 35 |

| 10 | Gastrodin Attenuates Pentylenetetrazole-Induced Seizures by Modulating the Mitogen-Activated Protein Kinase-Associated Inflammatory Responses in Mice显示文摘Gastrodin, the major component isolated from the rhizome of the Chinese traditional medicinal herb Gastrodia elata(‘‘Tianma''), has a long history in the treatment of epilepsy and other neurological disorders.However, the molecular mechanisms are not clear. Here,we found that gastrodin ameliorated pentylenetetrazole(PTZ)-induced epileptic seizures with improvement of the electroencephalographic pattern in mice. Further studies demonstrated that gastrodin decreased the levels of the pro-inflammatory cytokines interleukin-1b and tumor necrosis factor-a while increasing interleukin-10, an antiinflammatory cytokine in the brain. Furthermore, gastrodin attenuated the PTZ-induced microglial activation along with inhibition of mitogen-activated protein kinases,c AMP response element binding protein, and NF-j B. Our data suggest that gastrodin attenuates seizures by modulating the mitogen-activated protein kinase-associated inflammatory responses. | Liming Chen Xinan Liu Hua Wang Min Qu | 2017 | Neuroscience Bulletin2017,33,3: | 31 |
| 11 | Effects of large dose of dexamethasone on inflammatory mediators and pancreatic cell apoptosis of rats with severe acute pancreatitis显示文摘AIM: To investigate the influence of high dose of dexamethasone on inflammatory mediators and apoptosis of rats with severe acute pancreatitis (SAP). METHODS: SAP rats were randomly assigned to the model group and treatment group while the normal rats were assigned to the sham operation group. The mortality,ascite volumes,ascites/body weight ratio and pancreas pathological changes of all rats were observed at 3,6 and 12 h after operation. Their contents of amylase and endotoxin in plasma and contents of tumor necrosis factor (TNF-α),phospholipase A2 (PLA2) and IL-6 in serum were also determined. The microarray sections of their pancreatic tissues were prepared,terminal transferase dUTP nick end labeling (TUNEL) staining was performed and apoptotic indexes were calculated. RESULTS: There was no marked difference between treatment group and model group in survival. The contents of amylase and endotoxin in plasma and contents of TNF-α,PLA2 and IL-6 in serum,ascite volumes,ascites/body weight ratio and pancreas pathological scores were all lower in treatment group than in model group to different extents at different time points P < 0.05,58.3 (26.4) ng/L vs 77.535 (42.157) ng/L in TNF-α content,8.00 (2.00) points vs 9.00 (2.00) points in pathological score of pancreas respectively; P < 0.01,0.042 (0.018) EU/mL vs 0.056 (0.0195) EU/mL in endotoxin content,7791 (1863) U/L vs 9195 (1298) U/L in plasma amylase content,1.53 (0.79) vs 2.38 (1.10) in ascites/body weight ratio,8.00 (1.00) points vs 11.00 (1.50) points in pathological score of pancreas; P < 0.001,3.36 (1.56) ng/L vs 5.65 (1.08) ng/L in IL-6 content,4.50 (2.00) vs 7.20 (2.00),4.20 (1.60) vs 6.40 (2.30),3.40 (2.70) vs 7.90 (1.70) in ascite volumes,respectively. The apoptotic indexes of pancreas head and pancreas tail were all higher in treatment group than in model group at 6 h P < 0.01,0.00 (2.00)% vs 0.00 (0.00)%,0.20 (1.80) vs 0.00 (0.00) in apoptosis indexes,respectively. CONCLUSION: The mechanism of dexamethasone treatment in acute pancreatitis is related to its inhibition of inflammatory mediator generation and induction of pancreatic acinar cell apoptosis. | Xi-Ping Zhang Li Chen Qi-Fang Hu Hua Tian Ru-Jun Xu Zhi-Wei Wang Ke-Yi Wang Qi-Hui Cheng Wei Yan Yun Li Qing-Yu Li Qing He Fei Wang | 2007 | World Journal of Gastroenterology2007,13,41: | 29 |

| 15 | Risk factors for alcohol-related liver injury in the island population of China: A population-based case-control study显示文摘AIM:To investigate the association of alcohol dose, duration of drinking and obesity with abnormal alcohol-related liver injury indicators, the prevalence of alcohol-related liver injury in the island population of China.METHODS:Randomized multistage stratified cluster sampling from the island population of China was used in the population-based case-control study. Then interview, physical examination, laboratory assessments and ultrasonography were done. RESULTS:Daily alcohol intake ≥ 20 g, duration of drinking ≥ 5 years and obesity were closely related to alcohol-related liver injury (P < 0.05). The odds-ratio (OR) (95% CI) was 1.965 (1.122-3.442), 3.412 (1.789-6.507) and 1.887 (1.261-2.824), respectively. The prevalence rate of alcohol-related liver injury in ≥ 20 g daily alcohol intake group and < 20 g daily alcohol intake group was 37.14% and 12.06%, respectively. The prevalence rate of alcohol-related liver injury in ≥ 5 years drinking group and < 5 years drinking group was 34.44% and 8.53%, respectively. No significant dose-response relation was found between daily alcohol intake and abnormal alcohol-related liver injury indicators as well as between duration of drinking and abnormal alcohol-related liver injury indicators. There was no significant difference in the prevalence of alcohol-related liver injury between beer drinking group and yellow rice wine drinking group, hard liquor drinking group, multiple drinking group.CONCLUSION:The risk threshold of daily alcohol intake is 20 g and duration of drinking inducing alcohol-related liver injury 5 years in the island population of China. Liver injury induced by obesity should be concerned. | Zhe Shen You-Ming Li Chao-Hui Yu Yi Shen Lei Xu Cheng-Fu Xu Jin-Jin Chen Hua Ye Gen-Yun Xu | 2008 | World Journal of Gastroenterology2008,14,14: | 28 |
| 16 | B7-H1 expression is associated with expansion of regulatory T cells in colorectal carcinoma显示文摘AIM:To investigate the expression of B7-H1 in human colorectal carcinoma (CRC) to define its regulating effects on T cells in tumor microenvironment.METHODS:One hundred and two paraffin blocks and 33 fresh samples of CRC tissues were subject to this study.Immunohistochemistry was performed for B7-H1 and CD3 staining in CRC tissues.Ficoll-Hypaque density gradient centrifugation was used to isolate peripheral blood mononuclear cells of fresh CRC tissues;flow cytometry and immunofluorescence staining were used for detection of regulatory T cells.Data was analyzed with statistical software.RESULTS:Costimulatory molecule B7-H1 was found strongly expressed in CRC tissues,localized in tumor cell membrane and cytoplasm,while weak or none expression of B7-H1 was detected in pared normal colorectal tissues.Meanwhile,CD3 positive T cells were found congregated in CRC tumor nest and stroma.Statistic analysis showed that B7-H1 expression level was negatively correlated to the total T cell density in tumor nest (P<0.0001) and tumor stroma (P=0.0200) of 102 cases of CRC tissues.Among the total T cells,a variable amount of regulatory T cells with a clear Foxp3+ (forkhead box P3) staining could be detected in CRC tissues and patients' blood.Interestingly,in the 33 samples (15 cases of B7-H1 high CRC tissues and 18 cases of B7H1 low CRC tissues) of freshly isolated mononuclear cells from CRC tissues,the percentages of CD4+ Foxp3+ and CD8+ Foxp3+ regulatory T cells were found remarkably higher in B7-H1 high CRC tissues than in B7-H1 low CRC tissues (P=0.0024,P=0.0182),indicating that B7-H1 expression was involved in proliferation of regulatory T cell.No significant difference was found in CRC peripheral blood (P=0.0863,P=0.0678).PD-1 is the specific ligand for B7-H1 pathway transferring inhibitory signal to T cell,which is expressed by activated T cell.Our further analysis of PD-1 expression on T cells in CRC tissues showed that conventional T cells (CD4+ Foxp3/CD8+ Foxp3),which was thought to contribute to the anti-tumor immune response,highly expressed PD-1;while regulatory T cells (CD4+ Foxp3+/CD8+ Foxp3) almost failed to express PD-1.The average percentage of PD-1 expression on regulatory T cells was significantly higher than the percentage of PD-1 on conventional T cells (CD4+ Foxp3 T cell,P<0.0001;CD8+ Foxp3 T cell,P<0.0001).The diverse expression of PD-1 might lead to different fate of T cell subsets in B7-H1 over-expression CRC tumor microenvironment.CONCLUSION:B7-H1 expression in tumor cells can in hibit the conventional T cell proliferation in tumor micro environment through the PD-1 expression on conventiona T cells. | Dong Hua Jing Sun Yong Mao Lu-Jun Chen Yu-Yu Wu Xue-Guang Zhang | 2012 | World Journal of Gastroenterology2012,18,9: | 25 |
| 17 | Rapeseed research and production in China显示文摘Rapeseed(Brassica napus L.) is the largest oilseed crop in China and accounts for about 20% of world production.For the last 10 years,the production,planting area,and yield of rapeseed have been stable,with improvement of seed quality and especially seed oil content.China is among the leading countries in rapeseed genomic research internationally,having jointly with other countries accomplished the whole genome sequencing of rapeseed and its two parental species,Brassica oleracea and Brassica rapa.Progress on functional genomics including the identification of QTL governing important agronomic traits such as yield,seed oil content,fertility regulation,disease and insect resistance,abiotic stress,nutrition use efficiency,and pod shattering resistance has been achieved.As a consequence,molecular markers have been developed and used in breeding programs.During 2005–2014,215 rapeseed varieties were registered nationally,including 210 winter-and 5 spring-type varieties.Mechanization across the whole process of rapeseed production was investigated and operating instructions for all relevant techniques were published.Modern techniques for rapeseed field management such as high-density planting,controlled-release fertilizer,and biocontrol of disease and pests combined with precision tools such as drones have been developed and are being adopted in China.With the application of advanced breeding and production technologies,in the near future,the oil yield and quality of rapeseed varieties will be greatly increased,and more varieties with desirable traits,especially early maturation,high yield,high resistance to biotic and abiotic stress,and suitability for mechanized harvesting will be developed.Application of modern technologies on the mechanized management of rapeseed will greatly increase grower profit. | Qiong Hu Wei Hua Yan Yin Xuekun Zhang Lijiang Liu Jiaqin Shi Yongguo Zhao Lu Qin Chang Chen Hanzhong Wang | 2017 | The Crop Journal2017,5,2: | 25 |

| 19 | O-FIB:far-field-induced near-field breakdown for direct nanowriting in an atmospheric environment显示文摘Nanoscale surface texturing,drilling,cutting,and spatial sculpturing,which are essential for applications,including thin-film solar cells,photonic chips,antireflection,wettability,and friction drag reduction,require not only high accuracy in material processing,but also the capability of manufacturing in an atmospheric environment.Widely used focused ion beam(FIB)technology offers nanoscale precision,but is limited by the vacuum-working conditions;therefore,it is not applicable to industrial-scale samples such as ship hulls or biomaterials,e.g.,cells and tissues.Here,we report an optical far-field-induced near-field breakdown(O-FIB)approach as an optical version of the conventional FIB technique,which allows direct nanowriting in air.The writing is initiated from nanoholes created by femtosecondlaser-induced multiphoton absorption,and its cutting“knife edge”is sharpened by the far-field-regulated enhancement of the optical near field.A spatial resolution of less than 20 nm(λ/40,withλbeing the light wavelength)is readily achieved.O-FIB is empowered by the utilization of simple polarization control of the incident light to steer the nanogroove writing along the designed pattern.The universality of near-field enhancement and localization makes O-FIB applicable to various materials,and enables a large-area printing mode that is superior to conventional FIB processing. | Zhen-Ze Li Lei Wang Hua Fan Yan-Hao Yu Qi-Dai Chen Saulius Juodkazis Hong-Bo Sun | 2020 | Light(Science & Applications)2020,9,1: | 24 |
| 20 | Expression and clinical significance of high risk human papillomavirus and invasive gene in cervical carcinoma显示文摘Objective:To study the expression of E6 and E7 mRNA in high-risk human papillomavirus(HPV) HPV-18 and the relationship between the expression of invasive gene and cervical carcinoma.Methods:A total of 119 patients with cervical cancer,cervical erosion and cervical HPV infection who were diagnosed in our hospital were selected and randomly divided into two groups:cervical cancer group(n= 58) and non-cancerous group(n= 61).Another 60 patients with uterine leiomyoma were selected as normal control group.Detection of HPV18 E6,E7 mRNA expression and invasion,migration,proliferation inhibition genes,epithelial mesenchymal transition genes and proliferation related protein content.Results:The relative expression of E6 and E7 HPV-18 in cervical cancer group was significant higher than that in non-cancerous group and control group(mRNA)(P<0.05).The content of TRAF6 and c-FLIP in invasive cervical cancer group was significantly higher than that in non-cancerous group and control group(P<0.05).The mR NA content of CD44v6 and MMP-9 in cervical cancer group was significantly higher than that in non-cancerous group and control group(P<0.05).The content of DEC-1,IKK16,MBP-1 in cervical cancer group was significant lower than that in non-cancerous group and control group(P<0.05).The mR NA content of beta-catenin and Vimentin in cervical cancer group was significantly lower than that in non cancerous group and control group(P<0.05).The proliferation related protein E2F1 of cervical cancer group was significantly lower than that of non-cancerous group and control group,Bmi-1 content was significantly higher than non-cancerous group and control group(P<0.05).Conclusions:The expression of the detection of cervical cancer in high-risk human papilloma virus HPV-18 E6 and E7 mRNA,and the invasion,migration,proliferation inhibition gene,epithelial mesenchymal transition and proliferation related gene protein content,HPV expression rate of mR NA increased with the development of cervical cancer,the expression is also enhanced.The expression has a certain correlation between the level and development of cervical cancer.Through the above indicators,the development of cervical cancer monitoring and treatment to provide important clinical guidance. | Zhai Lu Hua Chen Xiao-Mei Zheng Man-Ling Chen | 2017 | Asian Pacific Journal of Tropical Medicine2017,10,2: | 24 |
