2003-2005年新生儿感染常见致病菌及耐药性的变迁

目的了解本地区新生儿2003至2005年感染常见致病菌的种类及耐药的现状，以指导临床合理应用抗生素。方法收集我院新生儿科2003年1月至2005年12月收治的613份体液培养阳性（痰液、血液、分泌物、胃液等标本）的患儿资料，对常见检出菌及其耐药性的变迁情况进行分析。结果共检出40种613株病原菌，以革兰阴性杆菌为主约占57．6％，而肺炎克雷伯菌和大肠埃希菌分别位于前二位，其产ESBLs菌株检出率分别为78．1％和82．6％。药敏结果显示，常见致病菌对青霉素、第一、二代头胞类抗生素、红霉素类耐药性显著增加，但对第三代头胞类抗生素如头孢曲松、头孢噻肟（凯福隆）、头孢他啶（复达欣）及B内酰胺酶抑制剂复方制剂、碳青霉烯类、万古霉素等较敏感。产ESBLs菌仅对亚胺培南及B内酰胺酶抑制剂复方制剂敏感。结论革兰阴性杆菌特别是肺炎克雷伯菌和大肠埃希菌是新生儿感染主要病原菌，产ESBLs菌比例增加应引起高度重视。碳青霉烯类、哌拉西林／三唑巴坦和头孢哌酮／舒巴坦，可作为新生儿严重医院感染经验用药，应尽量根据药敏试验调整抗生素。

靶重建放大扫描对肺孤立性结节病变的诊断意义

目的：探讨靶重建放大扫描技术对肺孤立性结节病变的诊断价值。方法：对63例患者先行常规CT平扫，选定结节处为兴趣区，行薄层靶重建放大扫描，层厚、层距为2mm，FOV为160。结果：42例恶性病变中有37例表现为深分叶，占88．1％；21例良性病变中有15例表现为浅分叶，占71．4％。恶性结节中15例内部出现条状低密度支气管征；7例出现血管集中征；8例出现空泡征；病变内部出现液化坏死13例，其中恶性病变ll例。22例出现钙化，包括12例良性病变和10例恶性病变。2例错构瘤内均见小面积脂肪性低密度影。结论：靶重建放大扫描比普通CT扫描可提供更多的信息，对良恶性病变的鉴别诊断有一定价值。恶性病变大多数为深分叶，良性病变大多数为浅分叶或无分叶。     

Pharmacy customers’ views and experiences of using pharmacies which provide needle exchange services in Aberdeen and Glasgow, Scotland

Community pharmacists contribution to the management of drug problems is considerable. As the use of illicit drugs has increased, pharmacists have come under increasing pressure to offer services to problem drug users. However, there is concern among some pharmacists that offering such services may deter other customers. There is particular concern among some pharmacists about needle exchange services. Only 9.5% of Scottish pharmacies offer needle exchange services compared to 69% which are dispensing methadone (57% of which supervise methadone consumption). Qualitative interviews were used in a purposive sample of 10 pharmacies in Scotland. Eight customers were interviewed in each pharmacy to ascertain pharmacy customers’ views on these services. The majority of customers were supportive of these services. Customers were often unaware that the pharmacy they were interviewed in was offering services for people with drug problems. Pharmacy customers were more knowledgeable about, and more supportive, of needle exchange services than they were of methadone. This was because they believed needle exchange services helped to reduce the amount of discarded needles in public places. Pharmacy customers also recognised that needle exchange helped reduce the spread of disease. These findings should be used to encourage more pharmacists to offer needle exchange services.     

外加磁场对半乳糖化白蛋白磁性阿霉素纳米粒在大鼠体内分布影响的研究

目的观察半乳糖化白蛋白磁性阿霉素纳米粒(ADR-GHMN)在正常肝脏中的靶向性,并观察ADR-GHMN在全身各脏器的分布特征及外加磁场对其分布的影响.方法大鼠正中开腹,肝动脉插管并固定,肝动脉注射125I-ADR-GHMN(相当于阿霉素0.5 mg/kg),左外叶加磁场,磁场应用30 min,移去磁场后,动物立即处死;对照组:肝动脉注射ADR-GHMN,左外叶不加磁场,30min后,移去磁场后,动物立即处死,立即取靶区肝、非靶区肝、肾、心、肺、小肠、脾及周围血作γ计数.肝组织作病理切片.结果注入的纳米粒75～85%分布于肝脏,其它脏器极少.病理切片显示磁区小动脉见大量纳米粒存在,对照组及非磁区肝中纳米粒很少见.结论ADR-GHMN在正常肝组织中有明显的磁靶向性;在磁场作用下,ADR-GHMN主要分布于肝脏,其它脏器含量很少;试验组肾、心、肺、小肠、脾及外周血于对照组的放射活性比较明显降低,表明磁性物质的存在使这些脏器的相对药物暴露明显减少.

炎性肠病药物治疗的循证医学研究进展

目的:从循证医学的角度解析炎性肠病药物治疗的相关进展。旨在提高对临床证据的认知,帮助临床医生评估新的治疗,从批判的视角重新看待以往的治疗。方法:收集国外近期相关文献进行评价。结果及结论:炎性肠病(IBD)的发病机制尚不清楚,众多的治疗方案可供选择。因此,循证医学研究结果有非常重要的临床指导意义。IBD的研究方面取得了可喜的进步。但是,有关CD活动指数(CDAI)和临床分型系统仍有待于改进。通过循证医学的研究证据有望确定安全和易于耐受的药物,并能发现目前诊治方面存在的缺陷和问题,更好地解决患者的病痛。
