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。     

脑膜转移癌诊疗现状

脑膜转移癌(CM)近年来发病率有所提升.其诊断为腰穿脑脊液及以核磁共振成像为主的影像学检查.治疗方法包括鞘内化疗、放射治疗、手术及对症支持,但具体治疗方案存在争议.目前推荐个体化治疗及综合治疗,靶向药物在本病中的应用有望取得较好的治疗效果.     

羟基红花黄色素A的Caco-2细胞摄取转运研究

 目的研究羟基红花黄色素A(HSYA)的胃肠吸收转运机制。方法采用Caco-2细胞模型考察孵育时间、介质pH、药物浓度及抑制剂(环孢菌素A和叠氮钠)对羟基红花黄色素A摄取转运的影响,并分析HSYA灌胃给药后在大鼠尿及粪中的累积排泄。结果HSYA的摄取符合被动扩散过程,pH7.8环境下药物的细胞摄取量[(1.05±0.045)mg·g^-1]低于pH5.4[(1.24±0.09)mg·g^-1](P<0.05),其在Caco-2单细胞层的表观透过系数(Papp)为(2.16±1.21)×10^-8cm·s^-1,加入环孢菌素A和叠氮钠后其Papp显著提高(P<0.05),分别为(47.92±17.8)×10^-8和(12.53±4.55)×10^-8cm·s^-1。HSYA大鼠灌胃给药(5.6mg·kg^-1)后31h,其尿和粪中的累积排泄量分别为给药剂量的0.74%和28.57%。结论HSYA的吸收基本符合被动扩散过程并有P-gp的参与,其黏膜透过性较差,碱性环境相对不利于药物的吸收。HSYA口服后的胃肠吸收较差,大量的药物被排出体外或在胃肠道内被代谢转化。     

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.

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。
