目的 探讨结核病在18氟-脱氧葡萄糖（18F-FDG）正电子发射断层扫描术（PET）中的影像学表现，提高对PET/CT在肺部包块诊断作用的认识，减少误诊。 方法 回顾分析2010年3月收治的1例肺结核合并纵隔淋巴结结核病患者的误诊及诊断治疗经过，分析误诊原因并总结诊治经验，结合文献复习肺部包块在PET/CT中的表现及临床特点。 结果 患者为肺部包块伴纵隔淋巴结包块，胸部CT提示肺癌伴纵隔淋巴结转移，PET/CT也考虑左肺下叶肺癌伴淋巴结转移。最后经纵隔镜淋巴结活检确诊结核，并抗结核治疗好转。 结论 结核等感染性疾病常可导致18F-FDG的摄取增加而造成PET/CT阳性结果，因此在18F-FDG PET/CT呈现阳性结果时须注意鉴别病变良恶性，其中高标准摄入值包块尤其需要注意与结核病相鉴别。
ObjectiveTo explore the effectiveness of lamividine (LAM) combined with adefovir (ADV) versus entecavir (ETV) for lamivudine-resistant (LAM-R) hepatitis B in renal transplant recipients. MethodOutpatients and inpatients of lamivudine-resistant kidney graft recipients with chronic hepatitis B admitted to West China Hospital and the People's Hospital of Santai County during Jan 2007 to Mar 2012 were divided into A group (LAM+ADV) and B group (ETV). And the level of alanine aminotransferase (ALT), level of serum creatinine, HBV serological markers and HBV-DNA load were compared by SPSS 16.0 software. ResultsA total of 15 patients were included. The mean age was 36.7±6.6 years old, the majority of patients were male. After treatment for 4 weeks, 12 weeks, 24 weeks, 48 weeks, 96 weeks, no significant differences were found between two groups in liver function normalization rates, the HBV-DNA negative conversion rates and serum creatinine level. ConclusionsLAM add-on ADV combination therapy and ETV monotherapy were both safe and effective in LAM-R kidney transplants with CHB, but the load of HBV-DNA in some patients were still positive at the endpoint. Elevated serum creatinine level may occur in some patients who treated with ADV. Consequently, for HBsAg-positive kidney transplantation patients, those anti-HBV drugs that are more effective, safer and less resistant may be better in the beginning of treatment.
目的 通过分析影响四川地区慢性乙型肝炎患者抗病毒治疗依从性的因素，探讨提高患者治疗依从性的策略。 方法 选择2011年4月－2012年4月在四川大学华西医院接受核苷（酸）类似物抗病毒治疗的324例慢性乙型肝炎患者作为研究对象。采用问卷调查的方法，对患者一般情况、心理状态、文化程度、经济情况、疾病认知情况、抗病毒疗效、服药持续性等相关因素进行分析，评估这些因素对患者治疗依从性的影响。 结果 324例患者中能够完全遵照医嘱者78例（24.07%），不能完全依从者246例（75.93%）。心理状态良好者132例（40.74%），其中依从性良好者54例；心理负担较重者192例（59.26%），其中依从性良好者24例。初中及以上学历204例（62.96%），依从性良好者72例；初中以下学历者120例（37.04%），依从性良好者仅6例。不同心理状态、文化程度的患者依从率差异有统计学意义。患者经济状况、年龄差异对于依从性也有一定影响。 结论 慢性乙型肝炎患者对抗病毒治疗的依从性与心理状态、文化程度者及经济状况密切相关。改善患者医疗费用偿付能力，对患者进行疾病认知教育以及减少社会歧视等措施有助于提高患者治疗依从性。
