2017年安徽省某三甲医院细菌耐药性监测

目的 了解铜陵市人民医院2017年临床分离细菌对抗菌药物的耐药状况。方法 对2017年1-12月临床分离菌采用纸片扩散法(KB)进行药敏试验，按CLSI 2017年版标准判读药敏试验结果，采用WHONET 5.6软件进行数据分析。结果 临床分离细菌共3436株，其中革兰阳性菌719株，占20.9%；革兰阴性菌2717株，占79.1%。耐甲氧西林金黄色葡萄球菌(MRSA)和耐甲氧西林凝固酶阴性葡萄球菌(MRCNS)的检出率分别为23.8%和72.3%，耐甲氧西林株对β-内酰胺类抗生素和其他测试抗菌药物的耐药率显著高于甲氧西林敏感株，未发现对万古霉素和替考拉宁耐药的葡萄球菌。粪肠球菌对青霉素、氨苄西林和呋喃妥因的耐药率较低，屎肠球菌对氯霉素的耐药率较低，5.3%屎肠球菌对万古霉素耐药。大肠埃希菌、克雷伯菌属(肺炎克雷伯菌和产酸克雷伯菌)和奇异变形菌中ESBLs的检出率分别为41.4%、50.7%和19.4%。肠杆菌科细菌中克雷伯菌属和沙雷菌属对碳青霉烯类抗生素耐药率较高，分别为37.5%和36.0%，其他菌属的耐药率低于3%。鲍曼不动杆菌对亚胺培南和美罗培南的耐药率分别80.3%和79.1%；铜绿假单胞菌对亚胺培南和美罗培南的耐药率分别为29.7%和28.4%。肺炎克雷伯菌、鲍曼不动杆菌和铜绿假单胞菌中广泛耐药株的检出率分别为31.3%(171/546)、0.6%(3/508)和0.7%(3/416)。结论 本院革兰阴性菌呈增多趋势，尤其广泛耐药的肺炎克雷伯菌应引起高度关注，做好细菌耐药性监测，加强临床抗菌药物的合理使用和医院感染控制。     

肺鳞癌治疗新靶点FGFR的研究进展

肺癌是目前全球发病率和死亡率均居前列的恶性肿瘤，其中肺鳞癌经手术、放化疗等综合治疗后，其疗效仍不满意。随着分子靶向治疗在肺腺癌中取得了令人瞩目的成果，而肺鳞癌患者中EGFR基因突变及ALK融合基因少见，急需探索新的靶点指导肺鳞癌患者的临床治疗。研究表明，FGFR家族（FGFR1-4）是肺鳞癌中突变频率较高的基因，FGFR基因的激活突变和扩增与肺鳞癌的发生和发展密切相关，同时许多小分子 FGFR 抑制剂在临床应用中已经取得较好的治疗效果。目前，许多FGFR抑制剂治疗肺鳞癌的临床试验也正在进行研究，针对FGFR靶点的基因治疗可为肺鳞癌的治疗提供一种新的策略。本文就FGFR在肺鳞癌的靶向治疗中的最新研究进展进行综述。     

产后产妇300例心理状态调查及应对措施

根据现代医学模式，健康的标准是躯体健康，心理健康和社会适应良好。妇女在妊娠期、分娩期和产褥期承受着躯体和精神上的巨大压力；产后由于身体的变化、社会角色的改变，对产妇的认知、情感、行为具有明显影响。焦虑是人们对环境中一些即将面临的，可能会造成危险和威胁的重大事件，或者要做出重大努力的情况中进行适应时，心理上出现紧张和一种不愉快的期待。探讨产后产妇的心理状态变化及其原因，采取有效的应对措施，以保证产妇的健康及至婴幼儿的健康成长。     

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.
