The purpose of this study is to characterize the re-epithelialization of wound healing in canine prostatic urethra and to evaluate the effect of this re-epithelialization way after two-micron laser resection of the prostate （TmLRP）. TmLRP and partial bladder neck mucosa were performed in 15 healthy adult male crossbred canines. Wound specimens were harvested at 3 days, and 1, 2, 3, and 4 weeks after operation, respectively. The histopathologic characteristics were observed by hematoxylin and eosin staining. The expression of cytokeratin 14 （CK14）, CK5, CK18, synaptophysin （Syn）, chromogranin A （CgA）, uroplakin, transforming growth factor-β1 （TGF-β1）, and TGF-β type Ⅱ receptor in prostatic urethra wound were examined by immunohistochemistry and real-time polymerase chain reaction, respectively. Van Gieson staining was performed to determine the expression of collagen fibers in prostatic urethra and bladder neck would. The results showed that the re-epithelialization of the prostatic urethra resulted from the mobilization of proliferating epithelial cells from residual prostate tissue under the wound. The proliferating cells expressed CK14, CK5, but not CK18, Syn, and CgA and re-epithelialize expressed uroplakin since 3 weeks. There were enhanced TGF-β1 and TGF-β type Ⅱ receptor expression in proliferating cells and regenerated cells, which correlated with specific phases of re-epithelialization. Compared with the re-epithelialization of the bladder neck, re-epithelialization of canine prostatic urethra was faster, and the expression of collagen fibers was relatively low. In conclusion, re-epithelialization in canine prostatic urethra resulted from prostate basal cells after TmLRP and this re-epithelialization way may represent the ideal healing method from anatomic repair to functional recovery after injury.

Energy equalizing routing for fast data gathering in wireless sensor networks

引用

The Journal of China Universities of Posts and Telecommunications 2007年第4期14卷 13-21页

Energy saving and fast responding of data gathering are two crucial factors for the performance of wireless sensor networks. A dynamic tree based energy equalizing routing scheme （DTEER） was proposed to make an effort to gather data along with low energy consumption and low time delay. DTEER introduces a dynamic multi-hop route selecting scheme based on weight-value and height-value to form a dynamic tree and a mechanism similar to token passing to elect the root of the tree. DTEER can simply and rapidly organize all the nodes with low overhead and is robust enough to the topology changes. When compared with power-efficient gathering in sensor information systems （PEGASIS） and the hybrid, energy- efficient, distributed clustering approach （HEED）, the simulation results show that DTEER achieves its intention of consuming less energy, equalizing the energy consumption of all the nodes, alleviating the data gathering delay, as well as extending the network lifetime perfectly.

作者： Jian Zhuo shu-jie Xia Department of Urology First People's Hospital Schoolof Medicine Shanghai Jiaotong University Shanghai200080 China

wollm thulium laser has become widely accepted because of the resultant excellent homeostasis and rapid vapo rization in prostatectomy. It is necessary for us to increase the surgical efficiency because of increasing numbers of largersized, eld erly and highrisk BPH patients. We have made efforts to achieve this goal through continued improvement of the 2~m thu lium laser equipment, innovative methods tangerine technique, reasonable teaching mode and easily grasped learning curve. We prove it necessary and feasible to increase the efficiency of 2μm thulium laser resection of the prostate. Transurethral resection of the prostate （TURP） is generally considered the ＇gold standard＇ for the surgical treatment of benign prostatic hyperplasia （BPH）,1 but its use is generally restricted to small and medium sized prostates.2 The complications and morbidities that have been related to this pro cedure, which include blood loss and distur bances in the fluid balance, have created a need for the development and investigation of newer techniques. Several laser devices working at various wavelengths have been introduced in the last few decades.3 One of these, the 2~tm thulium laser, is a surgical laser with optional continuous or pulse wave modes and a wavelength tunable from 1.75 to 2.22 ].tm.4 This laser presents many advantages over the holmium laser, such as an improved spatial beam quality, a more precise tissue incision and the capacity to operate in optional continuouswave or pulse modes.5＇6 Since 2004, we have used the thu lium laser in clinical practice primarily for urogenital endoscopic procedures, and its use has become widely accepted because ofthe resultant excellent homeostasis and rapid vaporization. TURP AND OPEN PROSTATECTOMY TECHNIQUES Considering the size of China＇s ageing popu lation, surgical morbidity is expected to consis tently increase among urological patients. Thus, we expect to treat more and more complex patients suffering from such serious condition

Cluster voltage control method for “Whole County” distributed photovoltaics based on improved differential evolution algorithm

引用

Frontiers in Energy 2023年第6期17卷 782-795页

作者： Jing ZHANG Tonghe WANG Jiongcong CHEN Zhuoying LIAO jie shu School of Energy Science and Engineering University of Science and Technology of ChinaHefei 230026China Guangzhou Institute of Energy Conversion Chinese Academy of SciencesGuangzhou 510640China Jiangsu Collaborative Innovation Center of Photovoltaic Science and Engineering Changzhou 213001China

China is vigorously promoting the “whole county promotion” of distributed photovoltaics (DPVs). However, the high penetration rate of DPVs has brought problems such as voltage violation and power quality degradation to the distribution network, seriously affecting the safety and reliability of the power system. The traditional centralized control method of the distribution network has the problem of low efficiency, which is not practical enough in engineering practice. To address the problems, this paper proposes a cluster voltage control method for distributed photovoltaic grid-connected distribution network. First, it partitions the distribution network into clusters, and different clusters exchange terminal voltage information through a “virtual slack bus.” Then, in each cluster, based on the control strategy of “reactive power compensation first, active power curtailment later,” it employs an improved differential evolution (IDE) algorithm based on Cauchy disturbance to control the voltage. Simulation results in two different distribution systems show that the proposed method not only greatly improves the operational efficiency of the algorithm but also effectively controls the voltage of the distribution network, and maximizes the consumption capacity of DPVs based on qualified voltage.

Discriminative tonal feature extraction method in mandarin speech recognition

引用

The Journal of China Universities of Posts and Telecommunications 2007年第4期14卷 126-130页

作者： huang Hao ZHU jie Department of Electronic Engineering Shanghai Jiao Tong UniversityShanghai 200240 China

To utilize the supra-segmental nature of Mandarin tones, this article proposes a feature extraction method for hidden markov model （HMM） based tone modeling. The method uses linear transforms to project Fo（fundamental frequency） features of neighboring syllables as compensations, and adds them to the original Fo features of the current syUable. The transforms are discriminatively trained by using an objective function termed as ＂minimum tone error＂, which is a smooth approximation of tone recognition accuracy. Experiments show that the new tonal features achieve 3.82% tone recognition rate improvement, compared with the baseline, using maximum likelihood trained HMM on the normal F0 features. Further experiments show that discriminative HMM training on the new features is 8.78% better than the baseline.
