The intermingling of regenerated nerve fibers inside nerve grafts is the main reason for mismatched nerve fibers. This is one of the key factors affecting limb function recovery after nerve injury. Previous research has shown that the accuracy of axon regeneration can be improved by a bionic structural implant. To this aim, iodine and freeze-drying high-resolution micro-computed tomography was performed to visualize the 3D topography of the New Zealand rabbit sciatic nerve (25 mm). A series of 1-, 2-, 3-, and 4-custom anatomy-based nerve conduits (CANCs) were fabricated based on the anatomical structure of the nerve fascicle. The match index, luminal surface, and mechanical properties of CANCs were evaluated before implanting in a 10-mm gap of the sciatic nerve. Recovery was evaluated by histomorphometric analyses, electrophysiological study, gastrocnemius muscle weight recovery ratio, and behavioral assessments at 12 and 24 weeks postoperatively. The accuracy of nerve regeneration was determined by changes in fluorescence-labeled profile number during simultaneous retrograde tracing. Our results showed that the optimal preprocessing condition for high-resolution micro-computed tomography visualization was treatment of the sciatic nerve with 40% Lugol’s solution for 3 days followed by lyophilization for 2 days. In vitro experiments demonstrated that the match index was highest in the 3-CANC group, followed by the 2-, 1-, and 4-CANC groups. The luminal surface was lowest in the 1-CANC group. Mechanical properties (transverse compressive and bending properties) were higher in the 3- and 4-CANC groups than in the 1-CANC group. In vivo experiments demonstrated that the recovery (morphology of regenerated fibers, compound muscle action potential, gastrocnemius muscle weight recovery ratio, pain-related autotomy behaviors, and range of motion) in the 3-CANC group was superior to the other CANC groups, and achieved the same therapeutic effect as the autograft. The simultan

Is the Use of Empirically Designed custom Soft Contact Lenses a Good Option for Challenging Patients?

引用

Open Journal of Ophthalmology 2013年第3期3卷 54-60页

作者： Frank Spors Donald J. Egan Lance E. McNaughton Jie Shen Matthew J. Lampa Pacific University College of Optometry Forest Grove USA Western University of Health Sciences College of Optometry Pomona USA

Purpose: Reasons for the lack of success for contact lens patients range from poor fit, to discomfort or to a less than optimum wearing schedule. This project was a preliminary investigation of customized soft toric contact lenses as an alternative for unsuccessful contact lens patients or potential drop-outs. Methods: Fifteen healthy non-compromised, previously unsuccessful contact lens wearing patients (13 women, 2 men) with ages from 21 to 33 years (25.1 ± 2.7 years) were the subjects for this study. They were empirically fitted with 15 astigmatic and 5 spherical customized SpecialEyes soft contact lenses. Visual acuities, comfort, lens movement, and rotation were evaluated. Results: Patients fitted with customized SpecialEyes soft contact lenses had statistically significant better visual acuities than with Phoropter Manifest Refraction. The lenses used in this study centered well and moved no more than 1 mm upon each blink. Lens rotation was less than 10 degrees for all toric lenses. Patients gave very positive vision and comfort ratings. Conclusion: This preliminary study supports the application of a software program to empirically design and manufacture Special Eyes custom soft lenses based upon corneal topographical parameters and subjective manifest refraction for those patients who either have challenging corneal parameters, high sphero-cylindrical prescriptions, or are currently dissatisfied with their contact lenses and are potential drop-outs.

On the custom of Sexual Hospitality in Marco Polo＇s The Description of the World

引用

World History Studies 2017年第1期4卷 36-51页

作者： Luo Wei Institute of History Studies Chines Academy of Social Sciences(CASS) Beijing P. R. China. This paper is a research finding of Marco Polo Project of Peking University.

The custom of sexual hospitality recorded in Marco Polo＇s The Description of the World, that is, to serve guests with wives and daughters, is a uniquely customary material. This paper shows that in lots of historical archives written in Chinese and other languages, similar records can also be identified. This indicates that the phenomenon is not an individual case in the history of human custom, and its traces can be discovered in the early stage of the development of many Eurasian ethnic groups. This also means that the formation and maintenance of such a custom is attributed to the biological demand of remote ethnic groups, that is, to acquire different genes. At the same time, the so- called ＂to please the deity＂ is actually the outcome conceived by those who manipulated religion to help rationalize and keep this custom. This research, actually, proves the authenticity and historical value of The Description of the World.

Analysis on the Impact of Folk custom on Targeted Poverty Alleviation

引用

Asian Agricultural Research 2018年第12期10卷 26-29,32页

作者： Xuetao LI College of Economics and Management Hubei University of Automotive Technology

Folk custom is specific embodiment of regional economy,society and culture,which has certain impact on targeted poverty alleviation work. Under the background,by analyzing logical relationship between folk custom and targeted poverty alleviation,and combining actual work experience,its impact on targeted poverty alleviation work is summarized. Analysis results show that folk custom has an active role in poverty alleviation through education,tourism and industry,and could obstruct poverty returning to certain degree. But its dross part brings stubborn conservatism,which hinders progress of regional thinking,reduces the effect of poverty alleviation,affects local people's behavior choice,and also obstructs popularization of poverty alleviation projects. Therefore,it needs conducting necessary guide and management of folk custom in targeted poverty alleviation work,changing existing habits and customs,developing advantages and avoiding disadvantages,which could improve the accuracy of poverty alleviation,and better achieve the goal of poverty alleviation.

引用

Journal of Landscape Research 2012年第6期4卷 64-66页

作者：王毅品何永祥连蕾重庆旅游职业学院重庆409000 西北大学陕西西安710002

Geographic conditions of southeast Chongqing were introduced, and characteristics of tourist landscapes in this area were analyzed by using connotations of tourism aesthetics and effect of "probability selection". Furthermore, aesthetic value of folk cultures was elaborated from the perspectives of basic aesthetic forms, such as beauty of ethnic buildings, folk customs, history and culture, and also special food. It was proposed that developing unique value of folk custom resources by applying tourism aesthetics and displaying the value in tourism development would contribute a lot to the preservation of beauty of local tourist cultures and development of tourism industry. Finally, suggestions were given for the protection and development of folk customs in southeast Chongqing in view of different development subjects, that is, government, tourist enterprises and the public.
