Dear Editor,Two cases of primary angle-closure glaucoma(PACG)with persistent shallow anterior chamber after phacoemulsification,intraocular lens(IOL)implantation and goniosynechialysis(GSL)were ***,which mainly presents with mechanical obstruction of the trabecular meshwork,is clinically characterized by elevated intraocular pressure(IOP)secondary to the apposition of peripheral iris or a synechial closure of the angle[1].A previous study reported that angle-closure glaucoma eyes experienced widening and deepening of anterior chamber angles following cataract extraction and IOL implantation,which could probably normalize the IOP[2].A randomized controlled trial demonstrated that in comparison with laser peripheral iridotomy(LPI),clear-lens extraction showed greater advantages in efficacy and cost-effectiveness and could be proposed as the first-line initial treatment for PACG[3].

Biological Activity and Antibacterial Property of Nano-structured TiO_2 Coating Incorporated with Cu Prepared by Micro-arc Oxidation

引用

Journal of Materials Science & Technology 2013年第3期29卷 237-244页

作者： Wei zhu Zhenxiang Zhang Beibei Gu Junying Sun Lixian zhu Orthopedic Department The First Affiliated Hospital of Soochow University Orthopedic Department Orthopedic DepartmentThe Affiliated Taizhou People's Hospital of Nantong University

Micro-arc oxidized Cu-incorporated TiO2 coatings （Cu-TiO2） were prepared in the Ca, P, Cu-containing electrolyte to obtain an implant material with superior biological activity and antibacterial property. The surface topography, phase, and element composition of the TiO2 and Cu-TiO2 coatings were characterized by scanning electron microscopy （SEM）, X-ray diffraction （XRD）, and energy-dispersive X-ray spectrometry （EDS）, respectively. Staphylococcus aureus （S. aureus） was selected to evaluate the antibacterial property of the Cu-TiO2 coatings, whereas osteoblastic MG63 cells were cultured on the coatings to investigate the biological activity. The obtained results demonstrated that Cu element was successfully incorporated into the porous nano-structured TiO2 coatings, which did not alter apparently the surface topography and phase composition of the coatings as compared to the Cu-free TiO2 coatings. Moreover, the antibacterial studies suggested that the Cu-incorporated TiO2 coatings could significantly inhibit the adhesion of S. aureus. In addition, the in vitro biological evaluation displayed that the adhesion, proliferation and differentiation of MG63 cells on the Cu-incorporated coatings were enhanced as compared to those on the Cu-free coatings and Ti plates. In conclusion, the innovative Cu-incorporated nano-structured TiO2 coatings on Ti substrate with excellent antibacterial property and biological activity are promising candidates for orthopedic implant.

作者： Qianhua Huang Chuyu Zhang Jiafu Wang Liezhen fu Ning Wang Yan zhu Jisen Huai Pengwei Zhang Jianshi Yu Hui Xu Wuhan Univ Inst Virol Wuhan 430072 Peoples R China

According to the previously published CSFV sequences, 18 pairs of primers have been designed and synthesized, which cover the entire genome of CSFV strain Shimen. Each cDNA fragment has been amplified by RT-PCR from the anticoagulant blood of strain Shimen infected pig. The PCR products have been cloned respectively and sequenced. Results show that the cDNA library of strain Shimen and its nucleotide sequence have been obtained. The genomic RNA of strain Shimen is 12 298 nucleotides in length, containing a 5’ and a 3’ noncoding region 373 and 231 nt long respectively. The center of genome is a single large open reading frame of 11 697 nt which encodes a polyprotein of 3 898 amino acids. The entire sequence of strain Shimen has also been compared with that of other CSFV strains.

Chimerically fused antigen rich of overlapped epitopes from latent membrane protein 2 （LMP2） of Epstein-Barr virus as a potential vaccine and diagnostic agent

引用

Cellular & Molecular Immunology 2016年第4期13卷 492-501页

作者： Xiaoyun Lin Shao chen Xiangyang Xue Lijun Lu Shanli zhu Wenshu Li Xiangmin chen Xiaozhi Zhong Pengfei Jiang Torsoo Sophia Sename Yi Zheng Lifang Zhang Department of Microbiology and Immunology Institute of Molecular Virology and Immunology Wenzhou Medical University Wenzhou China School of Laboratory Medicine and Life Science Wenzhou Medical University Wenzhou China

Epstein-Barr virus （EBV） is prevalent throughout the world and is associated with several malignant diseases in humans. Latent membrane protein 2 （LMP2） of EBV plays a crucial role in the pathogenesis of EBV-associated tumors; therefore, LMP2 has been considered to be a potential immunodiagnostic and immunotherapeutic target. A multi-epitope-based antigen is a promising option for therapeutic vaccines and diagnoses of such malignancies. In this study, we systematically screened cytotoxic T lymphocyte （CTL）, helper T cell （Th） and B-cell epitopes within EBV-LMP2 using bioinformatics. Based on the screen, two peptides rich in overlapping epitopes of both T cells and B cells were selected to construct a plasmid containing the sequence for a chimeric multi-epitope protein referred to as EBV-LMP2m, which is composed of LMP2aa195-232 and LMP2aa419-436. The EBV-LMP2m protein was expressed in E. coil BL21 （DE3） after prokaryotic codon optimization. Inoculation of the purified chimeric antigen in BALB/c mice induced not only high levels of specific IgG in the serum and secretory IgA in the vaginal mucus but also a specific CTL response. By using purified EBV-LMP2m as an antigen, the presence of specific IgG in the serum specimens of 202 nasopharyngeal carcinoma （NPC） patients was effectively detected with 52.84% sensitivity and 95.40% specificity, which represents an improvement over the traditional detection method based on VCA-IgA （60.53% sensitivity and 76.86% specificity）. The above results indicate that EBV-LMP2m may be used not only as a potential target antigen for EBV-associated tumors but also a diagnostic agent for NPC patients.

Implementation procedure for the generalized moving Preisach model based on a first order reversal curve diagram

引用

Rare Metals 2009年第4期28卷 355-360页

作者： HAN Yong zhu Jie State Key laboratory for Advanced Metals and Materials University of Science and Technology Beijing Beijing 100083 China

First order reversal curves （FORC） of nanocomposite Nd2Fe14B/Fe3B magnetic materials were measured to attain a FORC diagram, which characterizes reversible magnetization, irreversible magnetization, and magnetic interactions in a hysteresis system. Then, generalized mov- ing Preisach model （GMPM） was implemented based on the FORC diagram. Reversible and irreversible magnetizations shown in FORCs and a FORC diagram were used as an input of GMPM. Coupling interaction between reversible and irreversible magnetizations was added when calculating reversible magnetization. Meanwhile, irreversible magnetic moments＇ interaction was approximately represented by mean field interaction. The result shows that the simulated main curves mostly coincide with the experimental curves.

Oil Pollutants Degradation of Nano-MgO in Micro-Polluted Water

引用

Computational Water, Energy, and Environmental Engineering 2013年第3期2卷 12-15页

作者： Meng-fu zhu cheng Deng Hong-Bo Su Xiu-Dong You Lu zhu Ping chen Ying-Hai Yuan Institute of Medical Equipment Academy of Military Medical Sciences Tianjin

The removal of oil pollutants from water and purifying process of oil-polluted water are studied through catalytic degradation method with nano-MgO. The results indicated that catalytic degradation effect of nano-MgO on the oil pollutants was associated with dosage of nano-MgO, pH and water temperature. When oil content was 1.8 mg/L, 0.17 g nano-MgO was used and the removal rate of oil was 93.92%. furthermore, nano-Mgo was a non-photosensitive catalyst. GC/MS analysis showed that the amount of petroleum-based pollutants in water was reduced 73.77% from the previous 61 kinds to 16 kinds, and the total peak area was reduced 96.05% after catalytic degradation of nano-MgO. Therefore, nano-MgO has an excellent effect on the catalytic degradation of oil pollutants and can be applied in the treatment of oil wastewaters.
