2Early diagnosis of bacterial and fungal infection in chronic cholestatic hepatitis B显示文摘AIM: To investigate the early diagnostic methods of bacterial and fungal infection in patients with chronic cholestatic hepatitis B.METHODS: One hundred and one adult in-patients with chronic hepatitis B were studied and divided into 3 groups:direct bilirubin (DBil)/total bilirubin (TBil)≥0.5, without bacterial and fungal infection (group A, n=-38); DBil/TBil<0.5, without bacterial and fungal infection (group B, n=23),DBil/TBil≥0.5, with bacterial or fungal infection (group C,rr=-40). The serum biochemical index and pulse rate were analyzed.RESULTS: Level of TBil, DBil, alkaline phosphatase (ALP) and DBiI/ALP in group A increased compared with that in group B. The level of ALP in group C decreased compared with that in group A, whereas the level of TBil, DBil and DBiI/ALP increased (ALP: 156+43, 199+68, respectively,P<0.05, TBil: 370+227, 220+206, respectively, P<0.01,DBil: 214+143, 146+136, respectively, P<0.01, DBiI/ALP:1.65+1.05, 0.78+0.70, respectively, P<0.001). The level of DBil and infection affected DBiI/ALP. Independent of theeffect of DBil, infection caused DBiI/ALP to rise (P<0.05).The pulse rate in group A decreased compared with that in group B (63.7+6.4, 77.7+11.4, respectively, P<0.001),and the pulse rate in group C increased compared withthat in group A (81.2+12.2, 63.7+6.4, respectively, P<0.001).The equation (infection=0.218 pusle rate +1.064 DBiI/ALP-16.361), with total accuracy of 85.5%, was obtained from stepwise logistic regression. Pulse rate (≥80/min) andDBiI/ALP (≥1.0) were used to screen infection. The sensitivity was 62.5% and 64.7% respectively, and the specificity was 100% and 82.8% respectively.CONCLUSION: Bacterial and fungal infection deterioratejaundice and increase pulse rate, decrease serum ALP andincrease DBiI/ALP. Pulse rate, DBiI/ALP and the equation(infection=0.218 pusle rate+1.064 DBil/ALP-16.361) arehelpful to early diagnosis of bacterial and fungal infectionin patients with chronic cholestatic hepatitis B.Xiong-ZhiWu DanChen Lian-SanZhao Xiao-HuiYu MeiWei YanZhao QingFang Qianxu 2004World Journal of Gastroenterology2004,10,15:1

10Micellar Catalysis:Visible-Light Mediated Imidazo[1,2-a]pyridine C—H Amination with N-Aminopyridinium Salt Accelerated by Surfactant in Water显示文摘A light-promoted metal-free protocol for the amination of imidazo[1,2-a]pyridines with N-aminopyridinium salt by the assistance of surfactants in water was reported,charactering mild and environmentally benign conditions,as well as great functional group tolerance.Micelles with negatively charged polar surface and hydrophobic core formed from sodium dodecyl sulfate serve as an ideal medium for visible-light mediated radical reaction of cationic pyridine salt and imidazo[1,2-a]pyridine in aqueous phase.The electrostatic interaction between positively charged N-aminopyridinium and negatively charged surface of micelles is of great significance in this method.Zhonglie Yang Kun Cao Xiaoyan Peng Li Lin Danchen Fan Jun-Long Li Jingxia Wang Xiaobin Zhang Hezhong Jiang Jiahong Li 2021Chinese Journal of Chemistry2021,39,12:0
11Far-field super-resolution chemical microscopy显示文摘Far-feld chemical microscopy providing molecular electronic or vibrational fingerprint information opens a new window for the study of three-dimensional biological,material,and chemical systems.Chemical microscopy provides a nondestructive way of chemical identification without exterior labels.However,the diffraction limit of optics hindered it from discovering more details under the resolution limit.Recent development of super-resolution techniques gives enlightenment to open this door behind far-field chemical microscopy.Here,we review recent advances that have pushed the boundary of far-field chemical microscopy in terms of spatial resolution.We further highlight applications in biomedical research,material characterization,environmental study,cultural heritage conservation,and integrated chip inspection.Mingwei Tang Yubing Han Danchen Jia Qing Yang Ji-Xin Cheng 2023Light(Science & Applications)2023,12,7:0
12Shape retrieval by using multi-scale anglebased representation and dynamic label propagation显示文摘To improve the robustness and discrimination power of the triangle-area representation,a novel shape matching method based on multi-scale angle representation is proposed in this study.By analysing the configurations of different sample points from each shape contour,shape descriptors are constructed by using space angles at different scale levels.With the proposed shape representation,the multi-scale information of shape contours is efficiently described,and the dynamic programming is further used to determine the correspondence between samples from different shapes and calculate the shape distance in the feature matching step.Moreover,to improve the shape retrieval results based on pairwise shape distances,the dynamic label propagation is introduced as the post-processing step.Unlike previous distance learning methods learning the database manifold implicitly,the authors method retrieves relative objects on the shortest paths from near to far explicitly,and the underlying structure can be effectively captured.The proposed method tested on different shape databases provides the performances superior to many other methods,and it can be applied to visual data processing and understanding of the internet of things.Yanxia Yu Danchen Zheng Liang Zhao Chuang Sun Xiang Li Yan Zhuang 2020IET Cyber-Systems and Robotics2020,2,4:0
