目的 了解近5年来阴沟肠杆菌在我院的临床分布及耐药性的变迁情况。方法 采用K-B纸片法进行药物敏感性测定,再用双纸片法检测超广普β-内酰胺酶(ESBLs)。结果 2010年1月—2014年12月我院共分离阴沟肠杆菌261株,其中2010年分离48株(18.4%)、2011年50株(19.2%)、2012年52株(19.9%)、2013年54株(20.7%)、2014年57株(21.2株%);主要分布于重症监护室(ICU)、呼吸内科、肝胆外科,分别占49.%(130株)、14.9%(39株)、11.9%(31株),标本来源主要为痰液、尿液及伤口分泌物,分别占52%、13.5%、12.8%,ESBLs菌株的检出率为29.9%(78株),产酶株的耐药性高于非产酶株,全部菌株对亚胺培南敏感。结论 阴沟肠杆菌主要引起呼吸道、尿路和各种伤口感染,多发于ICU患者,并且呈逐年增多趋势,产ESBLs在阴沟肠杆菌中广为流行,合理使用抗菌药物(尤其是第三代头孢菌素)是减少产ESBLs株流行的重要措施。

Objective To investigate the clinical distribution and antimicrobial resistance of infections caused by enterobacter cloacae in our hospital. Methods Antimicrobial susceptibility tests were done by Kirby-Bauer disk diffusion method. The extended-spectrum β-Lactamases (ESLBS) were detected by double disc diffusion test. Results A total of 261 strains of E cloacae were isolated from Jan 2010 to Dec 2014. The percentages of these strains isolated in 2010, 2011, 2012, 2013, 2014 were 18.4%, 19.2%, 19.9%, 20.7%, 21.2% respectively. E cloacae were mainly isolated from intensive care unit (ICU) (49.0%), respiratory medicine (14.9%) and surgery (11.9%) respectively. The percentages of these strains isolated from sputum, urine and wound secretion were 52.0% 13.5% and 12.8% respectively. The percentages of ESBLS producer was 29.9% (78 strains).Their resistance was obviously higher than that of non-ESBLS producer. But all strain were sensitive to imipenem. Conclusion E Cloacae caused infections of respiratory tract, urinary and wound principally in clinic. The most of which occured in ICU. The ESBLS are popular in E cloacae and show the increasing trend year by year. The restricted use of antimicrobial drug is a considerable measure which reduces prevalence of ESBLS producing strains.

Objective To observe the clinical efficacy of lansoprazole enteric-coated tablets combined with flupentixol-melitracen in treating anxiety patients with erosive gastritis. Methods 106 patients with erosive gastritis and anxiety in our hospital from January 2013 to January 2015 were divided into an observation group and a control group, with 53 patients in each group. The control group was given lansoprazole enteric-coated tablets alone, and the observation group was treated with lansoprazole enteric-coated tablets and flupentixol-melitracen. Clinical symptoms and mucosal erosion were compared between the two groups of patients before and after treatment. Gastric mucosa malondialdehyde (MDA) and prostration E2 (PGE2) contents, anxiety and depression status were also assessed. Results After treatment, the scores of abdominal pain, bloating, acid reflux, belching, and mucosal erosions were significantly lower in the observation group than in the control group (P< 0.05). PGE2and MDA contents in the gastric mucosa in the observation group were different from those in the control group(P< 0.05). HAMA and HAMD scores were lower in the observation group than in the control group (P< 0.05). There was no difference of adverse reaction rate between the control group and the observation group (P>0.05). Conclusion Lansoprazole enteric-coated tablets combined with flupentixol-melitracen has better clinical efficacy than lansoprazole enteric-coated tablets only in patients with erosive gastritis and anxiety in terms of the improvement of clinical symptoms and mucosal erosion and the relief of negative emotions.

目的 探讨纵隔髓外造血(EMH)的临床特点,从而为其诊断、治疗提供参考意见。方法 总结分析我科收治的1例双侧后纵隔骨髓外造血组织多发瘤样增生,并对近10年来国内相关文献报道的27例病例进行回顾性分析。结果 患者需行手术活检取得病理诊断,确诊髓外造血。结论 纵隔髓外造血瘤样增生是一种罕见特殊的良性病变, 预后良好。但因其临床表现和影像学均缺乏特异性,当临床中遇到发生在后纵隔脊柱旁的占位性病变,同时患有贫血的患者应考虑EMH 的可能性,给予经皮穿刺或者胸腔镜下活检来取得细胞学诊断,从而避免不必要的手术治疗。

Objective To probe into the clinical features of mediastinal extramedullary hematopoiesis (EMH), for providing a reference for clinical diagnosis and treatment. Methods The clinical data was studied in a case of mediastinal EMH from our department, and 27 case reports from domestic published literatures over the last decade were analyzed retrospectively. Results Of the 27 patients, 15 received surgical excision, while the other 12 underwent needle biopsy. In our patient, the diagnosis of EMH was made by mini thoracotomy and open biopsy. Conclusion Mediastinal EMH is a rare disease and its prognosis is well. Because there is no obvious specific clinical symptoms and imaging appearances, the possibility of EMH should be considered when a patient with a mediastinal tumor associated with anemia is encountered. Diagnosis can be achieved by needle biopsy or video-assisted thoracic surgery (VATS) in order to prevent unnecessary surgical procedures.
