li–S and li–Se batteries have attracted tremendous attention during the past several decades, as the energy density of li–S and li–Se batteries is high（several times higher than that of traditional li-ion batteries）.Besides, li–S and li–Se batteries are low cost and environmental benign. However, the commercial applications of li–S and li–Se batteries are hindered by the dissolution and shuttle phenomena of polysulfide（polyselenium）, the low conductivity of S（Se）, etc. To overcome these drawbacks, scientists have come up with various methods, such as optimizing the electrolyte, synthesizing composite electrode of S/polymer, S/carbon, S/metal organic framework（MOF） and constructing novelty structure of *** this review, we present a systematic introduction about the recent progress of li–S and li–Se batteries, especially in the area of electrode materials, both of cathode material and anode material for li–S and li–Se batteries. In addition, other methods to lead a high-performance li–S and li–Se batteries are also briefly summarized, such as constructing novelty battery structure, adopting proper charge–discharge conditions, heteroatom doping into sulfur molecules, using different kinds of electrolytes and binders. In the end of the review, the developed directions of li–S and li–Se batteries are also pointed out. We believe that combining proper porous carbon matrix and heteroatom doping may further improve the electrochemical performance of li–S and li–Se batteries. We also believe that li–S and li–Se batteries will get more exciting results and have promising future by the effort of battery community.

Objective： To investigate the effects and complications of primary and secondary placements of motility coupling post （MCP） in the unwrapped porous polyethylene orbital implant （PPOI） following enucleation. Methods： We investigated 198 patients who received PPOI implantation following the standard enucleation procedure in the First Affiliated Hospital, School of Medicine, Zhejiang University, hangzhou, China, from 2002 to 2004. These patients were subgrouped into PPOI-only patients （112 cases, received PPOI following enucleation）, primary MCP patients （46 cases, received primary placement of MCP during PPOI operation）, and secondary MCP patients （40 cases, received secondary placement ofMCP 6 months after the initial surgery）. Effects and complications among these three groups were compared. Results： The PPOI-only patients took shorter treatment course when compared with other two MCP groups （P〈0.001）, without significant difference noted between the two MCP groups. However, the two MCP groups had better prosthetic motility than PPOI-only group （P〈0.001）, without significant difference between the two MCP groups. In the early stage, 2 eyes in the PPOI-only group and l eye in the primary MCP group had PPOI infection. In PPOI-only group, 3 （2.68%） eyes had PPOI exposure, which occurred after fitting the prostheses; 4 eyes （8.70%） in primary MCP group and 1 eye （2.50%） in secondary MCP had PPOI exposure, which occurred before fitting the prostheses. After prosthesis was fit successfully, the excessive discharge and granuloma were 33.9% and 1.79% in PPOI group-only, 53.3% and 8.9% in primary MCP group, and 52.5% and 7.5% in secondary MCP group, respectively. Conclusion： Both primary and secondary placements of MCP into the PPOI following enucleation can help patients to obtain desirable prosthetic motility, but may be associated with more complications. The primary placement of MCP with skilled operation in selected patients is more recommendable than secondary placemen

China has the largest high-speed railway(HSR) system in the world, and it has gradually reshaped the urban *** HSR system can be represented as different types of networks in terms of the nodes and various relationships(i.e.,linkages) between them. In this paper, we first introduce a general dual network model, including a physical network(PN)and a logical network(LN) to provide a comparative analysis for China’s high-speed rail network via complex network theory. The PN represents a layout of stations and rail tracks, and forms the basis for operating all trains. The LN is a network composed of the origin and destination stations of each high-speed train and the train flows between them. China’s high-speed railway(CHSR) has different topological structures and link strengths for PN in comparison with the LN. In the study, the community detection is used to analyze China’s high-speed rail networks and several communities are found to be similar to the layout of planned urban agglomerations in China. Furthermore, the hierarchies of urban agglomerations are different from each other according to the strength of inter-regional interaction and intra-regional interaction, which are respectively related to location and spatial development strategies. Moreover, a case study of the Yangtze River Delta shows that the hub stations have different resource divisions and are major contributors to the gap between train departure and arrival flows.

Template matching methods have been widely utilized to detect fabric defects in textile quality control. In this paper, a novel approach is proposed to design a flexible classifier for distinguishing flaws from twill fabrics by statistically learning from the normal fabric texture. Statistical information of natural and normal texture of the fabric can be extracted via collecting and analyzing the gray image. On the basis of this, both judging threshold and template are acquired and updated adaptively in real-time according to the real textures of fabric, which promises more flexibility and universality. The algorithms are experimented with images of fault free and faulty textile samples.

To the Editor One of the most significant demographic changes in our cotmtry is the increase in the elderly population. In China Mainland, the population aged 60 and older was 194 million in 2012, accounting for 14.3% of the total population. However, by 2053, it is estimated that the number of elderly will reach 487 million, representing 34.8% of the total population. Elderly patients represent an everncreasing populace in emergency medicine who often present with atypical signs and symptoms as well as eomorbidities that can complicate diagnoses and *** The geographic factors and the developmental status of the country can influence the spectrum of common geriatric emergencies. Thus, this study presents a retrospective analysis of common causes of geriatric emergencies involving 9,628 elderly patients from Jan. 2008 to Dec. 2013 in an emergency department in Beijing, China.

Background Infertility is a major medical and social problem, and elementary research on the spermatozoal proteins and their functions are relatively scarce and there are very few confirmed and effective options for the treatment of male infertility. Thus, it is essential to find candidate proteins that affect male infertility. This study was designed to detect the proteins with differential expression in sperm from infertile patients and normal *** Semen samples from patients with idiopathic asthenozoospermia （n=114） and from fertile men with normal spermiograms （n=37） were collected. Semen sample analysis, sperm protein extraction, SDS-PAGE electrophoresis and Western blotting analysis were performed. Results were analyzed by SPSS 16.0 statistical *** Western blotting analysis of spermatic proteins displayed a major differentially expressed protein in spermatozoa from fertile and idiopathic asthenozoospermia patients. Densities and volumes of the identified protein in the patients were significantly decreased compared to normal donors （P=0.034 and P=0.036, respectively）. The protein was identified as DEAD-box protein 4 （DDX4, VASA）. The expression and correction value （CV） of DDX4/VASA in the patients was reduced significantly compared to normal donors （P=0.037 and P=0.031, respectively）.Conclusions The expression of spermatic protein DDX4/VASA associates with spermatic motility, implying that DDX4NASA may be a candidate marker for evaluation of spermatic motility.
