| 1 | Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis. | Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao | 2000 | World Journal of Gastroenterology2000,6,6: | 52 |

| 3 | Leakage Prediction Method for Contacting Mechanical Seals with Parallel Faces显示文摘Since the beginning of the 20th century, many researches on the sealing characteristic of mechanical seals were carried out broadly and in depth by various methods and some leakage models were built. But due to the lack of the way to characterize the main factors of influence on the leakage, most of the early researches were based on the assumptions that the seal faces topography and the frictional conditions were invariant. In the early built models, the effect of the surface topography change of the seal face on the leakage rate was neglected. Based on the fractal theory, the contact of end faces of the rotary and stationary rings was simplified to be the contact of a rough surface and an ideal rigid smooth surface, and the contact interface’s cavity size-distribution function as well as the fractal characteristic of the cavity profile curve was discussed. By analyzing the influence of abrasion on the seal face topography and the leakage channel, the time-correlation leakage prediction model of mechanical seals based on the fractal theory was established and the method for predicting the leakage rate of mechanical seals with parallel plane was proposed. The values of the leakage rate predicted theoretically are similar to the measured values of the leakage rate in the model test and in situ test. The experimental results indicate that the leakage rate of mechanical seals is a transient value. The surface topography of the end faces of the seal rings and its change during the frictional wear of mechanical seals can be accurately characterized by the fractal parameters. Under the work conditions of changeless frictional mechanism, the fractal parameters measured or calculated based on the accelerated testing equation can be used to predict the leakage rate of mechanical seal in service. The proposed research provides the basis for determining the leakage state and predicting working life of mechanical seal. | SUN Jianjun WEI Long FENG Xiu GU Boqin | 2010 | Chinese Journal of Mechanical Engineering2010,23,1: | 16 |
| 4 | Xiaotan Sanjie decoction attenuates tumor angiogenesis by manipulating Notch-1-regulated proliferation of gastric cancer stem-like cells显示文摘AIM: To determine the underlying mechanisms of action and influence of Xiaotan Sanjie(XTSJ) decoction on gastric cancer stem-like cells(GCSCs). METHODS: The gastric cancer cell line MKN-45 line was selected and sorted by FACS using the cancer stem cell marker CD44; the stemness of these cells was checked in our previous study. In an in vitro study, the expression of Notch-1, Hes1, Vascular endothelial growth factor(VEGF), and Ki-67 in both CD44-positive gastric cancer stem-like cells(GCSCs) and CD44-negative cells was measured by Western blot. The effect of XTSJ serum on cell viability and on the above markers was measured by MTT assay and Western blot, respectively. In an in vivo study, the ability to induce angiogenesis and maintenance of GCSCs in CD44-positive-MKN-45- and CD44-negative-engrafted mice were detected by immunohistochemical staining using markers for CD34 and CD44, respectively. The role of XTSJ decoction in regulating the expression of Notch-1, Hes1, VEGF and Ki-67 was measured by Western blot and real-time polymerase chain reaction.RESULTS: CD44+ GCSCs showed more cell proliferation and VEGF secretion than CD44-negative cells in vitro, which were accompanied by the high expression of Notch-1 and Hes1 and positively associated with tumor growth(GCSCs vs CD44-negative cells, 2.72 ± 0.25 vs 1.46 ± 0.16, P < 0.05) and microvessel density(MVD)(GCSCs vs CD44-negative cells, 8.15 ± 0.42 vs 3.83 ± 0.49, P < 0.001) in vivo. XTSJ decoction inhibited the viability of both cell types in a dose-dependent manner in vitro. Specifically, a significant difference in the medium-(82.87% ± 6.53%) and high-dose XTSJ groups(77.43% ± 7.34%) was detected at 24 h in the CD44+ GCSCs group compared with the saline group(95.42% ± 5.76%) and the low-dose XTSJ group(90.74% ± 6.57%)(P < 0.05). However, the efficacy of XTSJ decoction was reduced in the CD44- groups; significant differences were only detected in the high-dose XTSJ group at 48 h(78.57% ± 6.94%) and 72 h(72.12% ± 7.68%) when compared with the other CD44- groups(P < 0.05). Notably, these differences were highly consistent with the Notch-1, Hes1, VEGF and Ki-67 expression in these cells. Similarly, in vivo, XTSJ decoction inhibited tumor growth in a dose-dependent manner. A significant difference was observed in the medium(1.76 ± 0.15) and high-dose XTSJ(1.33 ± 0.081) groups compared with the GCSCs control group(2.72 ± 0.25) and the low-dose XTSJ group(2.51 ± 0.25)(P < 0.05). We also detected a remarkable decrease of MVD in the medium-(7.10 ± 0.60) and high-dose XTSJ(5.99 ± 0.47) groups compared with the GCSC control group(8.15 ± 0.42) and the low-dose XTSJ group(8.14 ± 0.46)(P < 0.05). Additionally, CD44 expression was decreased in these groups [medium-(4.43 ± 0.45) and high-dose XTSJ groups(3.56 ± 0.31) vs the GCSC control(5.96 ± 0.46) and low dose XTSJ groups(5.91 ± 0.38)](P < 0.05). The significant differences in Notch-1, Hes1, VEGF and Ki-67 expression highly mirrored the results of XTSJ decoction in inhibiting tumor growth, MVD and CD44 expression.CONCLUSION: Notch-1 may play an important role in regulating the proliferation of GCSCs; XTSJ decoction could attenuate tumor angiogenesis, at least partially, by inhibiting Notch-1. | Bing Yan Long Liu Ying Zhao Li-Juan Xiu Da-Zhi Sun Xuan Liu Ye Lu Jun Shi Yin-Cheng Zhang Yong-Jin Li Xiao-Wei Wang Yu-Qi Zhou Shou-Han Feng Can Lv Pin-Kang Wei Zhi-Feng Qin | 2014 | World Journal of Gastroenterology2014,20,36: | 14 |

| 6 | New Vegetation Index and Its Application in Estimating Leaf Area Index of Rice显示文摘Leaf area index (LAI) is an important characteristic of land surface vegetation system, and is also a key parameter for the models of global water balancing and carbon circulation. By using the reflectance values of Landsat-5 blue, green and red channels simulated from rice reflectance spectrum, the sensitivities of the bands to LAI were analyzed, and the response and capability to estimate LAI of various NDVIs (normalized difference vegetation indices), which were established by substituting the red band of general NDVI with all possible combinations of red, green and blue bands, were assessed. Finally, the conclusion was tested by rice data at different conditions. The sensitivities of red, green and blue bands to LAI were different under various conditions. When LAI was less than 3, red and blue bands were more sensitive to LAI. Though green band in the circumstances was less sensitive to LAI than red and blue bands, it was sensitive to LAI in a wider range. When the vegetation indices were constituted by all kinds of combinations of red, green and blue bands, the premise for making the sensitivity of these vegetation indices to LAI be meaningful was that the value of one of the combinations was greater than 0.024, i.e. visible reflectance (VIS)>0.024. Otherwise, the vegetation indices would be saturated, resulting in lower estimation accuracy of LAI. Comparison on the capabilities of the vegetation indices derived from all kinds of combinations of red, green and blue bands to LAI estimation showed that GNDVI (Green NDVI) and GBNDVI (Green-Blue NDVI) had the best relations with LAI. The capabilities of GNDVI and GBNDVI to LAI estimation were tested under different circumstances, and the same result was acquired. It suggested that GNDVI and GBNDVI performed better to predict LAI than the conventional NDVI. | WANG FU min HUANG Jing feng TANG Yan lin WANG Xiu zhen | 2007 | Rice science2007,14,3: | 12 |
| 7 | Design of structured-light vision system for tomato harvesting robot显示文摘In order to improve the operating precision of the harvesting robot,a vision system for intelligently identifying and locating the mature tomato was designed.The active detection method based on structured-light stereo vision was expected to deal with the problem of variable illumination and target occlusion in the glasshouse.The maximum between-cluster variances of hue(H)and saturation(S)value were adopted as the threshold for color segmentation,which weakened the impact on the image caused by the light intensity variation.Through the limit on the pixel size and circularity of the candidate areas,the vision system recognized the fruit area and removed the noise areas.The fruit’s 3D position was computed on the basis of spatial relationship between the laser plane and the camera,when the linear laser was projected on the centre area of the mature fruit.The blue view-scanning laser stripe pixels on the mature fruit were extracted according to its Cb color characteristic.As the field test results show,the measurement error on the fruit radius is less than 5 mm,the centre distance error between the fruit and camera is less than 7 mm,and the single axis coordinate error is less than 5.6 mm.This structured-light vision system could effectively identify and locate mature fruit. | Feng Qingchun Cheng Wei Zhou Jianjun Wang Xiu | 2014 | International Journal of Agricultural and Biological Engineering2014,7,2: | 12 |

| 10 | A new strawberry harvesting robot for elevated-trough culture显示文摘In order to improve robotic harvesting and reduce production cost,a harvesting robot system for strawberry on the elevated-trough culture was designed.It was supposed to serve for sightseeing agriculture and technological education.Based on the sonar-camera sensor,an autonomous navigation system of the harvesting robot was built to move along the trough lines independently.The mature fruits were recognized according to the H(Hue)and S(Saturation)color feature and the picking-point were located by the binocular-vision unit.A nondestructive end-effector,used to suck the fruit,hold and cut the fruit-stem,was designed to prevent pericarp damage and disease infection.A joint-type industrial manipulator with six degrees-of-freedom(DOF)was utilized to carry the end-effector.The key points and time steps for the collision-free and rapid motion of manipulator were planned.Experimental results showed that all the 100 mature strawberry targets were recognized automatically in the harvesting test.The success harvesting rate was 86%,and the success harvesting operation cost 31.3 seconds on average,including a single harvest operation of 10 seconds.The average error for fruit location was less than 4.6 mm. | Feng Qingchun Wang Xiu Zheng Wengang Qiu Quan Jiang Kai | 2012 | International Journal of Agricultural and Biological Engineering2012,5,2: | 8 |
| 11 | Design and test of robotic harvesting system for cherry tomato显示文摘Harvesting of fresh-eating cherry tomato was highly costly on labor and time.In order to achieve mechanical harvesting for the fresh-eating tomato,a new harvesting robot was designed,which consisted of a stereo visual unit,an end-effector,manipulator,a fruit collector,and a railed vehicle.The robot configuration and workflow design focused on the special cultivating condition.Three key parts were introduced in detail:a railroad vehicle capably moving on both ground and rail was adopted as the robot’s carrier,a visual servo unit was used to identify and locate the mature fruits bunch,and the end-effector to hold and separate the fruit bunch was designed based on the stalk’s mechanical features.The field test of the new developed robot was conducted and the results were analyzed.The successful harvest rate of the robot was 83%,however,each successful harvest averagely needed 1.4 times attempt,and a single successful harvesting cycle cost 8 s excluding the time cost on moving. | Qingchun Feng Wei Zou Pengfei Fan Chunfeng Zhang Xiu Wang | 2018 | International Journal of Agricultural and Biological Engineering2018,11,1: | 8 |

| 15 | High salt diet accelerates the progression of murine lupus through dendritic cells via the p38 MAPK and STAT1 signaling pathways显示文摘The increased incidence of systemic lupus erythematosus(SLE)in recent decades might be related to changes in modern dietary habits.Since sodium chloride(NaCl)promotes pathogenic T cell responses,we hypothesize that excessive salt intake contributes to the increased incidence of autoimmune diseases,including SLE.Given the importance of dendritic cells(DCs)in the pathogenesis of SLE,we explored the influence of an excessive sodium chloride diet on DCs in a murine SLE model.We used an induced lupus model in which bone marrow-derived dendritic cells(BMDCs)were incubated with activated lymphocyte-derived DNA(ALD-DNA)and transferred into C57BL/6 recipient mice.We observed that a high-salt diet(HSD)markedly exacerbated lupus progression,which was accompanied by increased DC activation.NaCl treatment also stimulated the maturation,activation and antigenpresenting ability of DCs in vitro.Pretreatment of BMDCs with NaCl also exacerbated BMDC-ALD-DNA-induced lupus.These mice had increased production of autoantibodies and proinflammatory cytokines,more pronounced splenomegaly and lymphadenopathy,and enhanced pathological renal lesions.The p38 MAPK–STAT1 pathway played an important role in NaClinduced DC immune activities.Taken together,our results demonstrate that HSD intake promotes immune activation of DCs through the p38 MAPK–STAT1 signaling pathway and exacerbates the features of SLE.Thus,changes in diet may provide a novel strategy for the prevention or amelioration of lupus or other autoimmune diseases. | Ze Xiu Xiao Xiaojiang Hu Ximei Zhang Zhigang Chen Julie Wang Ke Jin Feng Lin Cao Baoqing Sun Joseph A.Bellanti Nancy Olsen Song Guo Zheng | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 6 |
| 16 | Xiaotan Tongfu granules contribute to the prevention of stress ulcers显示文摘AIM:To investigate the efficacy and potential mechanism of Xiaotan Tongfu granules(XTTF)in stress ulcers.METHODS:One hundred sixty rats were randomly divided into 4 groups(n=10)as follows:the model group(MP group),the control group(CP group),the ranitidine group(RP group)and the XTTF granule group(XP group).Rats in the MP group received no drugs,rats in the CP group received 0.2 mL of a 0.9%sodium chloride solution via oral gavage,and rats in the RP and XP groups received the same volume of ranitidine(50 mg/kg)or XTTF granule(4.9 g/kg).The cold-restraint stress model was applied to induce stress ulcers after 7 consecutive days of drug administration.Afterwards,rats were sacrificed at 0,3,6 and24 h.Gastric pH was measured by a precise pH meter;gastric emptying rate(GER)was measured by using a methylcellulose test meal;myeloperoxidase activity(MPO),macrophage migration inhibitory factor(MIF),proliferating cell nuclear antigen(PCNA),and heat shock protein 70(HSP70)were measured by immunohistochemical staining;and mucosal cell apoptosis was measured by transferase dUTP nick end labeling.RESULTS:In the cold-restraint stress model,the development of stress ulcers peaked at 3 h and basically regressed after 24 h.Gastric lesions were significantly different in the RP and XP groups at each time point.Interestingly,although this index was much lower in the RP group than in the XP group immediately following stress induction(7.00±1.10 vs 10.00±1.79,P<0.05.Concerning gastric pH,between the RP and XP groups,we detected a statistically significant difference immediately after stress induction(0 h:4.56±0.47 vs 3.34±0.28,P<0.05)but not at any of the subsequent time points.For GER,compared to the RP group,GER was remarkably elevated in the XP group because a statistically significant difference was detected(3 h:46.84±2.70 vs 61.16±5.12,P<0.05;6 h:60.96±6.71 vs 73.41±6.16,P<0.05;24 h:77.47±3.17 vs 91.31±4.34,P<0.05).With respect to MPO and MIF,comparisons between the RP and XP groups revealed statistically significant differences at 3 h(MPO:18.94±1.20 vs 13.51±0.89,P<0.05;MIF:150.67±9.85 vs 122.17±5.67,P<0.05)and 6 h(MPO:13.22±1.54 vs 8.83±0.65,P<0.05;MIF:135.50±9.46 vs 109.83±6.40,P<0.05).With regard to HSP70,HSP70 expression was significantly increased in the RP and XP groups at 3 and 6 h compared to the MP and CP groups.In addition,comparing the RP and XP groups also showed statistically significant differences at 3 and 6 h.The expression of PCNA was higher in the RP and XP groups 3 h after stress induction.Between these two groups,small but statistically significant differences were observed at all of the time points(3 h:69.50±21.52 vs 79.33±15.68,P<0.05;6 h:107.83±4.40 vs 121.33±5.71,P<0.05;24 h:125.33±5.65 vs 128.50±14.49,P<0.05)except 0 h.With regard to apoptosis,the apoptotic activity in the RP and XP groups was significantly different from that in the MP and CP groups.The XP group exhibited a higher inhibition of cell apoptosis than the RP group at3 h(232.58±24.51 vs 174.46±10.35,P<0.05)and6 h(164.74±18.31 vs 117.71±12.08,P<0.05).CONCLUSION:The Xiaotan Tongfu granule was demonstrated to be similar to ranitidine in preventing stress ulcers.It exhibited multiple underlying mechanisms and deserves further study. | Bing Yan Jun Shi Li-Juan Xiu Xuan Liu Yu-Qi Zhou Shou-Han Feng Can Lv Xiu-Xia Yuan Yin-Cheng Zhang Yong-Jin Li Pin-Kang Wei Zhi-Feng Qin | 2013 | World Journal of Gastroenterology2013,19,33: | 6 |
| 17 | A Hierarchical P2P Model and a Data Fusion Method for Network Security Situation Awareness System显示文摘A hierarchical peer-to-peer(P2P) model and a data fusion method for network security situation awareness system are proposed to improve the efficiency of distributed security behavior monitoring network. The single point failure of data analysis nodes is avoided by this P2P model, in which a greedy data forwarding method based on node priority and link delay is devised to promote the efficiency of data analysis nodes. And the data fusion method based on repulsive theory-Dumpster/Shafer(PSORT-DS) is used to deal with the challenge of multi-source alarm information. This data fusion method debases the false alarm rate. Compared with improved Dumpster/Shafer(DS) theoretical method based on particle swarm optimization(PSO) and classical DS evidence theoretical method, the proposed model reduces false alarm rate by 3% and 7%,respectively, whereas their detection rate increases by 4% and 16%, respectively. | GUO Fangfang HU Yibing XIU Longting FENG Guangsheng WANG Shuaishuai | 2016 | Wuhan University Journal of Natural Sciences2016,21,2: | 5 |

| 19 | Ethnic Differences in Preterm Birth Risks for Pregnant Women with Thyroid Dysfunction or Autoimmunity:A Meta-analysis显示文摘Objective Abnormal maternal thyroid function is associated with preterm birth.However,this association stays dubious in relevant individual studies for ethnic difference reasons and lack of direct supporting data.This study aimed to evaluate the relationship between preterm birth and thyroid dysfunction or autoimmunity based on ethnic differences.Methods Relevant studies were identified through searches of MEDLINE,Excerpta Medica,Wan Fang,China Biological Medicine disc,and China National Knowledge Infrastructure from inception to June 15,2016.Original articles in which an incidence or prevalence of thyroid dysfunction or autoimmunity before second trimester of pregnancy could be extracted were included.Results Thirty-two unique studies were included for the final meta-analysis.Patients involved were divided into two groups:Group 1(G1) and Group 2(G2) comprising of Asian and Caucasian populations,respectively.Positive thyroid antibodies were associated with the occurrence of preterm birth in both G1 [odds ratio(OR):3.62,95% confidence interval(CI):2.83-4.65] and G2(OR:1.35,95% CI:1.17-1.56);hypothyroidism,only in G2(OR:1.20,CI:1.09-1.33);and subclinical hypothyroidism or hypothyroxinemia,in neither group.Conclusion Thyroid autoimmunity may be a more favorable factor leading to preterm birth among pregnant women of different ethnicities,compared with thyroid dysfunction. | LI Min WANG Shao Wei WU Feng Li SHI Jin YU Pu Lin PENG Xiu Ling SUN Liang | 2016 | Biomedical and Environmental Sciences2016,29,10: | 5 |
| 20 | Effects of Outdoor Temperature on Blood Pressure in a Prospective Cohort of Northwest China显示文摘Objective The relationship between outdoor temperature and blood pressure(BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season.Methods A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011–2015 were included in the study. A linear mixed-effect model and generalized additive mixed model(GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables.Results The mean differences in systolic blood pressure(SBP) and diastolic blood pressure(DBP)between summer and winter were 3.5 mm Hg and 2.75 mm Hg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mm Hg(95% CI: 0.27–0.30) per 1 °C decrease in average temperature for SBP and a 0.16 mm Hg(95% CI: 0.15–0.17) per 1 °C decrease in average temperature for DBP, respectively. The effects of the average temperature on both SBP and DBP were stronger in summer than in other seasons. The effects of the average temperature on BP were also greater if individuals were older, male, overweight or obese, a smoker or drinker, or had cardiovascular diseases(CVDs), hypertension, and diabetes.Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics(age, gender, BMI), unhealthy behaviors(smoking and alcohol consumption), and chronic disease status(CVDs, hypertension, and diabetes). | ZHENG Shan WANG Min Zhen CHENG Zhi Yuan KANG Feng NIE Yong Hong MI Xiu Ying LI Hai Yan JIN Lan ZHANG Ya Wei BAI Ya Na | 2021 | Biomedical and Environmental Sciences2021,34,2: | 5 |
