小分子抗血管生成药物在非小细胞肺癌中的研究进展

肺癌是世界上发病率最高的癌症之一，且尚无二线进展后的标准治疗方案，而肿瘤血管生成目前已被确定为恶性肿瘤的重要治疗靶点，小分子多靶点血管激酶抑制剂可通过抑制血管生成相关信号通路，抑制肿瘤血管的生成。目前已开展多项小分子抗血管生成药物治疗非小细胞肺癌的临床试验，且已有部分血管内皮生长因子受体酪氨酸激酶抑制剂（vascular endothelial growth factor receptor-tyrosine kinase inhibitors, VEGFR-TKIs）获批治疗晚期非小细胞肺癌，本文基于国内外多项小分子抗血管生成药物治疗非小细胞肺癌的发展现状，归纳了多个VEGFR-TKIs及成纤维细胞生长因子受体（fibroblast growth factor receptor, FGFR）-TKI单药或联合[包括分别与化疗、表皮生长因子受体（epidermal growth factor receptor, EGFR）-TKIs、免疫治疗、放疗等联合）]治疗非小细胞肺癌的疗效与安全性研究，同时探讨了VEGFR-TKIs可能存在的耐药机制及疗效预测指标等，并对未来抗血管治疗非小细胞肺癌的发展趋势以及存在的潜在问题进行展望，同时为肺癌后续的精准治疗及个体化治疗提供新的思路。     

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease

BackgroundPercutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported.ObjectivesTo compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors.MethodsWe reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients’ characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed.ResultsDuring the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development.ConclusionsBBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.

Anticipatory perioperative management for patent ductus arteriosus surgery: Understanding postligation cardiac syndrome

Ligation of a hemodynamically significant ductus arteriosus results in significant changes in loading conditions which have predictable consequences. Postligation cardiac syndrome, defined as hypotension requiring inotropic support and failure of oxygenation and ventilation, may occur 6‐12 hours following ligation due to left ventricular systolic and diastolic failure, respectively. Afterload is the primary driver of this decompensation. In this review, we describe the pathophysiological changes in loading conditions associated with postligation cardiac syndrome and other contributors to cardiovascular dysfunction following ductal ligation. We present strategies for perioperative optimization and a physiology‐based algorithm for postoperative management guided by targeted neonatal echocardiography. The use of these strategies to reduce the frequency of postligation deterioration may be an avenue to improve outcomes for neonates in this vulnerable patient population.     

辛味中药在治疗消渴证中的应用价值及中药五味理论现代研究的思考

辛味是中药五味学说中的重要性味之一,通常具有“发散”“行气”和“行血”的作用,且辛味中药在传统医学临床应用中占有较大比例。结合中药辛味的功效内涵及传统中医理论对消渴证的认识,阐述辛味中药与消渴证治疗之间的内在联系,总结辛味中药对“消渴三消”的治疗意义与价值。并在此基础上,对中药五味理论的现代研究趋势和发展方向进行思考,为同行研究提供参考。
