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。     

以肺动脉高压为首发表现的先天性中枢性低通气综合征临床特征和基因分析

目的探讨先天性中枢性低通气综合征(CCHS)的临床和基因变异特征。方法分析1例首发表现为不明原因肺动脉高压的CCHS患儿的临床资料,并总结国内外文献中CCHS病例的临床特点、致病机制和基因变异情况。结果11月龄女婴,主要表现为浮肿、尿少、低血压、嗜睡、发绀、抽搐及颅内压增高。B型脑利钠肽、丙氨酸氨基转移酶升高,凝血酶原时间延长。颅脑磁共振示右侧额叶出血;超声心动图示中重度肺动脉高压。靶向捕获二代测序未发现可能的致病基因。采用Sanger法验证示患儿PHOX 2 B基因第3外显子存在多聚丙氨酸重复扩展变异,基因型为20/25。患儿入院后采用无创通气,睡眠时呼吸浅慢、微弱,伴血氧下降;血气分析提示二氧化碳潴留。随后改用夜间无创通气、降肺压药物治疗。复查肺动脉压力明显下降,生命体征稳定。随访至24月龄,夜间只需较低压力水平的无创通气,生长发育无异常。结论对于不明原因的肺动脉高压伴撤机困难患儿,需警惕CCHS。疑诊者应尽早针对CCHS相关基因进行靶向捕获二代测序及PHOX 2 B基因Sanger法验证。早期给予无创通气有望改善预后。     

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.     

诺和锐胰岛素治疗儿童1型糖尿病的临床观察

目的:观察诺和锐胰岛素治疗儿童1型糖尿病的疗效。方法:对10例应用诺和灵短效胰岛素联合诺和灵中效胰岛素治疗的1型糖尿病患儿以超短效胰岛素诺和锐等量替代短效胰岛素联合诺和灵中效胰岛素治疗1个月,观察HbA1c等代谢指标变化。结果:用诺和锐治疗后患儿餐后2 h血糖、HbA1c显著下降,P<0．01,平均下降值分别为3．51±1．10 mmol／L与0．64％±0．19％。胰岛素用量与血脂无明显变化,P>0．05。治疗期间未发现明显低血糖。结论:超短效胰岛素诺和锐替代短效胰岛素可进一步控制餐后血糖．并显著降低HbA1c,有利于血糖控制。     

颈内动脉起始部血管成形术治疗缺血性脑血管病的疗效观察

目的 探讨颈内动脉起始部血管成形术治疗缺血性脑血管病的临床效果。方法 对15例缺血性脑血管病术前行全脑血管造影与超声检查，狭窄部位支架置入、球囊扩张，比较术前、术后狭窄程度的改善，术后随访1～34个月。结果 术后狭窄程度明显改善，围手术期无并发症。随访期内无缺血性脑血管病事件发生．但有脑出血的发生。结论 支架置入血管成形术是值得选择的缺血性脑血管病病因治疗方法之一；多个部位支架置入是安全的；支架的选择、手术的技巧以及严格的适应证掌握是影响手术的重要因素，特别要警惕预防高灌注综合征的发生，注意患者的心理评价与治疗。
