目的:重症脑出血微创术后气管切开病人痰培养病原菌分布与耐药情况分析,其院内感染发生的原因、探讨防治对策。方法:应用痰培养检出的病原菌及耐药性分析。结果:重症脑出血微创术后气管切开病人下呼吸道感染41例,其中G-杆菌26例占63.4%,G 球菌15例占36.6%,其中金葡菌11例,药敏仍以敏感菌株为主,但耐药菌株有增多趋势。结论:重症脑出血微创术后气管切开病人下呼吸道感染以G-杆菌为主,G 球菌以金葡菌为主,仍以敏感菌珠为主,耐药有增多趋势。万古霉素对G 球菌,氨曲南对G-杆菌敏感性较敏感,故在培养结果未出来之前经验用药是非常重要的。 相似文献

目的 探讨肿瘤微血管密度(MVD)与肝细胞性肝癌临床病理及预后的关系。方法对30例肝细胞性肝癌根治性切除病理组织切片进行苏木精伊红染色.并用CD34单克隆抗体进行免疫组化染色,计数被CD34抗体染色的肿瘤血管内皮细胞数,以测定MVD。对MVD与临床病理因素及术后生存率关系进行分析。结果 单因素分析结果表明.MVD水平与肿瘤大小、TNM分期都是影响肝细胞性肝癌预后的因素;多因素分析结果表明.肝癌大小及肿瘤分期是肝细胞性肝癌独立预后因素。结论 MVD是肝细胞性肝癌一种预后因素。 相似文献

The sequence is presented of RNA-5 of Echinochloa hoja blanca tenuivirus, a second tenuivirus associated with rice cultivation in Latin America (after rice hoja blanca virus). The RNA is 1334 nucleotides long and contains in the complementary sense RNA a single long open reading frame. The deduced amino acid sequence of this open reading frame shows that it encodes a highly basic and hydrophilic 44 kD protein (pc5) with about 50% similarity to the pc5 protein of maize stripe virus (MStV). This and other features of the RNA are discussed.The GenBank accession number of the sequence reported in this paper is L47430. 相似文献

Micro vascular free tissue transfer scores over the traditional myocutaneous flaps by providing better cosmesis and function.
However, the increased operating tine and costs and the necessity for two operating teams sometimes, negate these advantages
and even where this facility is freely available, myoentancous flaps continue to be widely used.
To determine the ideal choice of reconstruction in patients after oral resection, we compared our experience with these two
methods of reconstruction. Since 1997, when we first started micro vascular reconstruction, 17 patients have undergone this
procedure for oral reconstruction. During this same period, 40 patients had pectoralis major myocutaneous flap reconstruction
of the oral cavity. These two groups are compared with regard to cosmetic and functional results (as measured by patient’s
level of satisfaction) operating time, duration of hospitalization, cost and complications.
Results: Eightv seven percent of the patients in the micro vascular group and 75% in the myocutaneous group were satisfied
with the cosmetic and functional results. In the microvascular group, average operating time was increased by 4 hours; hospitalization
by 3 days and average cost of treatment was doubled. Flap failures and re-explorations were significantly higher in the micro
vascular group.
Based on these results, we would like to suggest the ideal method of reconstruction of the oral cavity in specific subgroups
of patients in a corporate hospital setting. 相似文献

Abstract Synthetic micro/nanomotors (MNMs) are novel, self-propelled nano or microscale devices that are widely used in drug transport, cell stimulation and isolation, bio-imaging, diagnostic and monitoring, sensing, photocatalysis and environmental remediation. Various preparation methods and propulsion mechanisms make MNMs “tailormade” nanosystems for the intended purpose or use. As the one of the newest members of nano carriers, MNMs open a new perspective especially for rapid drug transport and gene delivery. Although there exists limited number of in-vivo studies for drug delivery purposes, existence of in-vitro supportive data strongly encourages researchers to move on in this field and benefit from the manoeuvre capability of these novel systems. In this article, we reviewed the preparation and propulsion mechanisms of nanomotors in various fields with special attention to drug delivery systems. 相似文献

目的:分析在喂养不耐受早产儿中联合应用小剂量红霉素、微生态制剂的临床治疗效果。方法选取2013年8月-2014年12月该院收治的102例喂养不耐受早产儿,采用随机数字表法分为对照组(采用微生态制剂予以治疗)和研究组(采用小剂量红霉素+微生态制剂予以治疗),每组各51例,比较两组早产儿的治疗效果。结果①研究组早产儿的治疗总有效率为90.33%(47/51),对照组为67.31%(35/51),研究组早产儿的疗效明显高于对照组(P<0.05);②两组早产儿均未见不良反应,安全性好。结论在喂养不耐受早产儿中联合应用小剂量红霉素和微生态制剂,效果显著,且具有良好的安全性,值得推广。 相似文献
