In our experience patients undergoing circumcision are mostly concerned about pain and penile appearances. We conducted a prospective randomized trial to assess the benefits of a new disposable circumcision suture device （DCSD）. A total of 942 patients were equally divided into three groups （conventional circumcision, Shang ring and disposable suture device group）. Patients in the DCSD group were anesthetized with compound 5% lidocaine cream, the others with a 2% lidocaine penile block. Operation time, intra-operative blood loss, incision healing time, intra-operative and post-operative pain, the penile appearance and overall satisfaction degree were measured. Operation time and intra-operative blood loss were significantly lower in the Shang ring and suture device groups compared to the conventional group （P 〈 0.001）. Intra-operative pain was less in the suture device group compared With the other two groups （P 〈 0.001）; whereas post-operative pain was higher in the conventional group compared to the other two groups （P 〈 0.001）. Patients in the suture device （80.57%） and Shang ring （73,57%） groups were more satisfied with penile appearances compared with the conventional circumcision group （20.06%, P 〈 0.05）. Patients in suture device group also healed markedly faster than the conventional group （P 〈 0.01）. The overall satisfaction rate was better in the suture device group （78.66%） compared with the conventional （47.13%） and Shang ring （50.00%） groups （P 〈 0.05）. The combination of DCSD and lidocaine cream resulted in shorter operation and incision healing times, reduced intra-operative and post-operative pain and improved patient satisfaction with the cosmetic appearances.

Mapping of QTL conferring leaf rust resistance in Chinese wheat lines W014204 and Fuyu 3 at adult plant stage

引用

Journal of Integrative Agriculture 2016年第1期15卷 18-28页

作者： QI Ai-yong ZHANG pei-pei ZHOU Yue YAO Zhan-jun LI zai-feng LIU Da-qun Department of Plant Pathology College of Plant Protection Agricultural University of Hebei Department of Biochemistry Baoding University College of Agronomy Agricultural University of Hebei

Wheat leaf rust is a destructive foliar disease of common wheat （Triticum aestivum L.） worldwide. The most effective, economical s to control the disease is growing resistant cultivars with adult plant resistance （APR）. The Chinese wheat tines W014204 and Fuyu 3 showed high leaf rust resistance in the field. To identify leaf rust APR genes in the two lines, two mapping populations with 215 and 163 F2：3 lines from the crosses W014204/Zhengzhou 5389 and Fuyu 3/Zhengzhou 5389, respectively, were phenotyped for leaf rust severities during the 2010-2011, 2011-2012 and 2012-2013 cropping seasons in the field at Baoding, Hebei Province, China. A total of 1 215 SSR markers were used to identify the quantitative trait loci （QTLs） for leaf rust APR in the two populations. In the W014204/Zhengzhou 5389 population, three QTLs were detected and designated as ***-lBL.1, ***-2BS.1 and ***-7DS, and explained 2.9-8.4, 11.5-38.3 and 8.5-44.5% of the phenotypic variance, respectively; all the resistance alleles at these loci were derived from W014204. In the Fuyu 3/Zhengzhou 5389 population, three QTLs, ***-lBL.2, ***-2BS.2 and ***-7BL, explained 12.0-19.2, 22.3-38.9 and 4.1-4.3% of the phenotypic variance, respectively, and all resistance alleles were contributed by Fuyu 3. Based on chromosome positions of closely linked markers, both ***-lBL. 1 and ***-lBL.2 are Lr46, and ***-7DS is Lr34. ***-7BL was mapped on chromosome 7BL near to Lr68 and they are likely the same gene. Based on chromosome positions, pedigree and field reactions, the two 2BS QTLs are different from all the known APR genes and are likely to be newAPR QTL for leaf rust. These QTLs and their closely linked markers are potentially useful for improving leaf rust resistance in wheat breeding.

Novel Kinetic Method for Expressing the Ability of Antioxidant to Scavenge Radicals

引用

Chemical Research in Chinese Universities 2013年第5期29卷 947-951页

作者： LI Yan-feng LI pei-ze LIU zai-qun Department of Organic Chemistry College of Chemistry Jilin University Changehun 130012 t~ R. China

A method was developed to treat the result from an antioxidant trapping radicals including 2,2＇-azinobis （3-ethylbenzothiazoline-6-sulfonate） cationic radieal（ABTS＋＇）, 2,2＇-diphenyl-l-picrylhydrazyl radical（DPPH）, and galvinoxyl radical. In the presence of a certain concentration of an antioxidant, the decrease of the concentration of a kind of radicals follows the second order exponential function with the increase of the reaction time（t）, v＆., [radical]=Ae-t/a＋Be rib＋c, the derivation operation of which obtains the differential style, -d[radical]/dt= （A/a）e t/a＋（B/b）e-t/b, revealing the relationship between the reaction rate（r=-d[radical]/dt） and the reaction time（t）. Thus, the reaction rate at the beginning of the reaction@0） can be calculated by assigning t=-0 in the equation of -d[radical]/dt-t. Based on the concept of the reaction rate, r=k[radical][antioxidant], the rate constant（k） can be calculated based on r0 and the initial concentrations of radical and antioxidant, k=-r0/（[radieal]o[antioxidant]0）. The k means the rate of a fresh antioxidant molecule to trap a fresh radical. This method was used to treat the interactions of ABTS＋＇, DPPH, and galvinoxyl radicals with three homoisoflavonoids, four pyrazoles, and three ferrocenyl Schiff bases. It was found that ferrocenyl group is beneficial for antioxidants to reduce ABTS＋＇, and ortho-hydroxyl group is beneficial for antioxidants to donate hydrogen atom in phenolic hydroxyl group to DPPH and galvinoxyl radicals.

引用

International Journal of Minerals,Metallurgy and Materials 2009年第5期16卷 608-614页

作者： Min Zheng pei-jun Wei School of Applied Science University of Science and Technology Beijing Beijing 100083 China

Band gaps of elastic waves in 1-D phononic crystals with imperfect interfaces were studied. By using the transfer matrix method （TMM） and the Bloch wave theory in the periodic structure, the dispersion equation was derived for the periodically lami- nated binary system with imperfect interfaces （the traction vector jumps or the displacement vector jumps）. The dispersion equation was solved numerically and wave band gaps were obtained in the Brillouin zone. Band gaps in the case of imperfect interfaces were compared with that in the case of perfect interfaces. The influence of imperfect interfaces on wave band gaps and some interesting phenomena were discussed.

The solutions of navigation observation equations for CAPS

引用

Science China(Physics,Mechanics & Astronomy) 2009年第3期52卷 434-444页

作者： SHI HuLi pei jun National Astronomical Observatories Chinese Academy of SciencesBeijing 100012China

Chinese scientists invent the navigation and positioning system based on commercial communications satellites and develop them successfully into China Area Positioning System (CAPS). In principle, this system is different from the GPS broadcasting satellite navigation class, where the propagation epoch of original navigation signals for pseudo-range measurement is from a ground master control station rather than from satellite transponders. This paper addresses the establishment of the three observation equation models for the navigation and positioning system based on communications satellites, and expresses them identically to operator equations and optimized models. Furthermore, both algorithms of the linear solution for the observable characteristic equation and the least-squares solution for the condition number more than 4 are discussed, with several methods for the exact solution, such as improving the behavior of coefficient matrices, right estimation for the weighted right hand side and selection of iteration forms of solutions, and the influence of the condition number on improving navigation and positioning accuracy is also analyzed carefully. Hopefully, all the works would be contributive to further development of the navigation and positioning system based on communications satellites, and be potentially valuable to other satellite navigation and positioning systems.

作者： pei jun-ying ZHANG Xue-jun Dept. of Math. Soochow Univ. Suzhou 215006 China

Quasi-cyclic codes of length mn over Z4 are shown to be equivalent to A-submodules of A^n, where A = Z4[x]/（x^m - 1）. In the case of m being odd, all quasi-cyclic codes are shown to be decomposable into the direct sum of a fixed number of cyclic irreducible A-submodules. Finally the distinct quasi-cyclic codes as well as some specific subclasses are enumerated.

Multiple teleportation via partially entangled GHZ state

引用

Frontiers of physics 2016年第4期11卷 101-108页

Quantum teleportation is important for quantum comrmmication. We propose a protocol that uses a partially entangled Greenberger-Horne-Zeilinger （GHZ） state for single hop teleportation. Quantum teleportation will succeed if the sender makes a Bell state measurement, and the receiver performs the Hadamard gate operation, applies appropriate Pauli operators, introduces an auxiliary particle, and applies the corresponding unitary matrix to recover the transmitted state. We also present a protocol to realize multiple teleportation of partially entangled GHZ state without an auxiliary particle. We show that the success probability of the teleportation is Mways [） when the number of teleportat, ions is odd. In order to improve the success probability of a multihop, we introduce the method used in our single hop teleportation, thus proposing a multiple teleportation protocol using anxiliary particles and a unitary matrix. The final success probability is shown to bc improved significantly for the method without auxiliary particles fbr both an odd or even number of teleportations.
