The synthesis and catalytic properties of copper nanoparticles（Cunps） were reported using L-ascorbic acid as reducing and capping agent in aqueous medium. The effect of different concentrations of L-ascorbic acid on the particle size of Cunps was investigated. The synthesized Cunps were characterized by UV-Visible spectrophotometer, scanning electron microscopy（SEM）, transmission electron microscopy（TEM） and Fourier transform infrared（FTIR） spectrophotometer. The result indicates that the size of copper nanoparticles decreases with the increase in concentration of L-ascorbic acid. L-Ascorbic acid plays an important role to protect the copper nanoparticles from oxidation and agglomeration which helps nanoparticles to get better stability for the application. The synthesized Cunps show excellent catalytic activity in the oxidation of serine（Ser） by peroxomonosulphate（PMS）. The catalytic activity of Cunps increases with the decrease in size of Cunps. The Cunps are expected to be suitable alternative and play an imperative role in the fields of catalysis and environmental remediation.

Iliopsoas abscess(IPA) is an uncommon infection. The clinical presentation is usually insidious. Most patients present with nonspecific symptoms, leading to difficulty in prompt and accurate diagnosis. Delay in diagnosis can lead to complications, such as sepsis and death. Tattooing has become more popular over the recent years and has been associated with tattooing-related and blood-borne infections. We present two related cases of methicillin-resistant Staphylococcus aureus IPA after tattooing and review the epidemiology, etiology, clinical features, and management of IPA.

Perifollicular granuloma is a unique histologic feature and whether it is associated with immunoglobulin G4(IgG 4)-related disease is controversial. We report a case of a 38-year-old man who presented with worsening left eye pain, proptosis, tearing, gritty sensation, blurred vision and multiple lymphadenopathy. An axillary lymph node resection showed reactive follicular and interfollicular lymph node hyperplasia, and increased eosinophils and plasma cells(at least 80% of Ig G+ plasma cells were positive for IgG 4). A distinct feature was the presence of multifocal, perifollicular histiocytic granulomas, which formed a wreath around the entire follicles. The human herpes virus 8 was not detected by immunohistochemistry. In addition, an extensive panel of special stains, immunohistochemistry, and flow cytometry was negative for lymphoma, fungal, or mycobacterial infection. The findings were suggestive of IgG 4-related sclerosing disease-associated lymphadenopathy. Further laboratory testing showed a significant increase of serum immunoglobulin E(> 23000 IU/mL) and slight increase of total Ig G, but normal serum Ig G4. Even though perifollicular granuloma is a nonspecific histopathologic feature and can be seen in other diseases, such as nodular lymphocyte predominant Hodgkin lymphoma, Ig G4-related lymphadenopathy should be listed in the differential diagnoses of benign reactive lymph nodes, especially when perifollicular granuloma and plasmacytosis coexist.

嗜水气单胞菌(Aeromonas hydrophila)是水环境常见的病原体,具有较强致病性。在本研究中,首次敲除了嗜水气单胞菌aguA基因,通过转录组分析发现aguA基因敲除后细菌的黏附、致病、胺代谢等生物过程下降。通过qRT-PCR进一步验证发现10个黏附基因、9个发病基因和8个胺代谢基因的mRNA表达水平明显下降;此外,转录组水平分析结合qRT-PCR验证发现Ⅵ型分泌系统基因、Ⅱ型分泌系统基因、鞭毛合成相关基因、菌毛合成相关基因、溶血基因、Ⅰ型分泌系统基因、肠毒素基因、RTX基因等毒力基因的RNA表达水平也出现下调。与野生菌株(WT)相比,aguA敲除株(ΔaguA)感染金鱼的致病力降低了86.6%,且aguA敲除株生物膜形成能力降低了16.6%。以上结果显示,aguA基因与嗜水气单胞菌的致病性密切相关。
