Comparative Study of the Genetic Diversity,Antimicrobial Resistance,and Pathogenicity of Aeromonas Isolates from Clinical Patients and Healthy Individuals

Objective This study was performed to compare the genetic diversity, virulence, and antimicrobial resistance of Aeromonas strains isolated from patients and healthy individuals. Methods A total of 38 clinical strains and 19 strains from healthy individuals were isolated from the samples collected in Ma'anshan City, Anhui Province. Their taxonomy was investigated using concatenated gyrB-cpn60 sequences, and their resistance to 12 antibiotics was evaluated. The pathogenicity of these strains was examined through beta-hemolysis, protease activity, and virulence gene assays. Results The 57 Aeromonas strains were divided into 55 sequence types. Of these types, 21 were novel, suggesting that their genetic diversity was high. These Aeromonas isolates could be divided into 7 species, and the positive rates of beta-hemolysis and protease activity were 49.1％ and 73.7％, respectively. The detection rate of clinical patients in terms of beta-hemolysis and protease activity was higher than that of healthy individuals. Among the four most common Aeromonas strains, A. dhakensis had the highest detection rate of virulence genes. The multidrug resistance rate of the clinical isolates was much higher than that of the strains isolated from healthy individuals. Conclusions The taxonomy, virulence properties, and antibiotic resistance of Aeromonas isolates from patients differ from those of the isolates from healthy individuals.

幼年和成年猪松质骨脱细胞基质有机成分和成骨诱导能力的比较

目的：比较幼年和成年猪松质骨脱细胞基质（DCBM）的成骨特性。方法：制备幼年和成年猪DCBM并验证脱细胞效果。胶原和糖胺聚糖（GAGs）定量检测、Masson三色和阿利新蓝染色评估脱细胞前后胶原和GAGs含量及分布。免疫组化检测松质骨基质中骨形态发生蛋白-2（BMP-2）、基质金属蛋白酶-13（MMP-13）和骨钙蛋白（OCN）的分布情况。qPCR检测幼年和成年DCBM诱导复植间充质干细胞（MSC）的I型胶原（Col-I）、碱性磷酸酶（ALP）、BMP-2和OCN等成骨分化指标的基因表达。纳米液相色谱-串联质谱（LC-MS/MS）分析DCBM的蛋白组成。结果：定量分析显示,幼年松质骨较成年松质骨在脱细胞前后胶原和GAGs含量更高。幼年松质骨脱细胞前后BMP-2、MMP-13、OCN等的表达均高于成年松质骨。成骨诱导实验显示复植于幼年DCBM的MSC,ALP、Col-I等的mRNA的表达量高于复植于成年DCBM。蛋白质谱GO分析和丰度分析显示幼年DCBM较成年DCBM肽链种类丰富,包含成纤维细胞生长因子、转化生长因子、胰岛素样生长因子等促骨生长细胞因子。结论：同等条件下制备的幼年DCBM与成年猪DCBM比较含有更丰富的促骨生长细胞因子,具有更强的成骨诱导性能。     

Evolución del cierre de ileostomía en una unidad de cirugía colorrectal. Análisis comparativo según la técnica

Introduction

The objective of this study is to assess whether the results of loop ileostomy closure in terms of morbidity and hospital stay are influenced by the type of anastomosis and suture used.

Method

All patients who underwent loop ileostomy closure were reviewed. A retrospective cohort study comparing morbidity and hospital stay according to the type of anastomosis (TT/LL) and the type of suture (hand sewn/mechanical) was performed.

Results

From January 2003 to November 2011 a total of 167 loop ileostomy closures were analized. The groups were: type of anastomosis (TT 95/LL 72) and type of suture (manual 105/stapled 62). In 76% of the observed population the underlying disease was cancer. Mortality occurred in one case. The stratified morbidity analysis by type of complications showed no significant differences between the groups in terms of local (7.4% TT, LL 8.3%, 6.7% hand sewn, stapled 9.7%), general (TT 9.5%, 16.7% LL, hand sewn 6.7%, 6.5% stapled) and surgical (TT 15.8%, 19.4% LL, hand sewn 17.1%, 17.7% stapled) complications, nor in the rate of reoperations (TT 6.3%, 6.9% LL, hand sewn 6.7%, 6.5% stapled) and hospital stay in days (TT 7.8, 8 LL, hand sewn 8.6, stapled 6.7)

Conclusions

Closure of loop ileostomy can be performed regardless of the type of suture or anastomosis used, with the same rate of morbidity and hospital stay.     

术中 X-线定位在神经内镜切除甲介型蝶窦垂体瘤手术中的应用简

目的探讨术中x-线定位在经神经内镜下甲介型蝶窦垂体瘤手术的应用。方法回顾性分析6例甲介型蝶窦垂体瘤病人的临床资料,均采用神经内镜下垂体瘤切除结合术中X-线定位方法。结果术中X-线定位准确4例;2例发生纵向偏差,均纠正。肿瘤全切除5例,次全切除1例。术后激素水平正常,视力视野改善。出现暂时性尿崩1例,治疗后痊愈。无脑脊液鼻漏、垂体功能低下、蝶窦炎发生,无死亡病例。6例病人随访3年,均无复发。结论神经内镜技术结合术中X-线定位是一种治疗甲介型蝶窦垂体瘤的安全、有效方法。     

皮肤吻合器在神经外科手术中的应用

目的探讨皮肤吻合器在神经外科手术切口缝合中的应用效果。方法我科自2010年9月至2014年1月对120例神经外科手术切口采用不同方法进行皮肤缝合,根据缝合方法分为吻合器组和传统组,各60例;吻合器组采用一次性皮肤吻合器缝合切口,传统组采用传统丝线缝合切口。观察记录两组手术缝合速度、术后脑脊液切口漏发生率、切口感染发生率、切口缘皮肤坏死发生率。结果吻合器组缝合速度为（9.5±0.7）cm/min,术后脑脊液切口漏发生率为1.7%（/60）,无切口感染及切口缘皮肤坏死病例;传统组缝合速度为（3.4±0.3）cm/min,术后脑脊液切口漏发生率为10%（6/60）,切口感染发生率为3.3%（2/60）,切口缘皮肤坏死发生率为13.3%（8/60）;两组切口吻合速度及术后切口缘皮肤坏死发生率均差异显著（P〈0.05）。结论对于神经外科手术切口,皮肤吻合器缝合皮肤切口较传统丝线缝合有明显的优势。
