新辅助化疗后门静脉系统全置换治疗局部进展期胰腺癌一例报告

患者女性,65岁,局部进展期胰腺癌伴门静脉、肠系膜上静脉和肠系膜上动脉侵犯,经6个周期奥沙利铂+氟尿嘧啶+伊立替康+亚叶酸钙(FOLFIRINOX)新辅助化疗后,肿瘤评估为部分缓解,但仍属于局部进展期胰腺癌。患者行动脉优先入路、全门静脉系统切除、异体血管置换重建的扩大胰十二指肠切除术,同时运用异体血管体外成形技术。患者术后已无瘤生存28个月。FOLFIRINOX新辅助化疗方案可使部分局部进展期胰腺癌患者疾病达到稳定状态,而异体血管体外成形技术的应用为门静脉系统全切除置换提供了一种新的方法,使患者有机会达到根治性手术切除,从而改善远期预后。     

Pharmacokinetics and distribution of schisandrol A and its major metabolites in rats

1.?Schizandrol A is an active component in schisandra, also the representative component for the identification of schisandra.

2.?A rapid resolution liquid chromatography coupled with quadruple–time–of–flight mass spectrometry (RRLC–QTOF/MS) was developed to investigate the pharmacokinetics of schizandrol A after its intragastric administration (50?mg/kg) in rats.

3.?Schizandrol A was rapidly absorbed (T _max = 2.07?h), with a longer duration (t _1/2 = 9.48?h) and larger apparent volume of distribution (Vz/F?=?111.81?l/kg) in rats. Schizandrol A can be detected in main organs and the order of its distribution was in the liver?>?kidney?>?heart?>?spleen?>?brain, particularly higher in the liver.

4.?Five schizandrol A metabolites were identified, including 2–demethyl–8(R)–hydroxyl–schizandrin, 3–demethyl–8(R)–hydroxyl–schizandrin, hydroxyl–schizandrin, demethoxy–schizandrin, 2, 3–demethyl–8(R)–hydroxyl–schizandrin, indicating that the hydroxylation and demethylation may be the major metabolic way of schizandrol A.

5.?This study defined the pharmacokinetic characteristics of schizandrol A in vivo, and the RRLC–QTOF/MS is more sensitive and less limited by conditions, and needs less samples, which may be a useful resource for the further research and development of schisandrol A.     

探讨创新管理理念下医院管理的方法与实践

目的分析创新管理理念下医院管理的方法与实践工作。方法对创新管理理念组和常规管理组进行回顾性分析,比较两组的医疗服务效果。结果创新管理理念组在医疗质量、医技水平、服务水平、就医环境、医风医德的总体评分以及医护人员满意度上均优于常规管理组。结论切合医院实际创新的内部管理理念,能够提升医院的服务质量,提高医院的竞争力。     

复方鲜药外敷治疗肿瘤性溃疡伤口临床研究

目的:观察复方鲜药外敷对肿瘤性溃疡伤口的治疗效果。方法:选取肿瘤性溃疡伤口患者60例,按随机数字表法分为观察组和对照组各30例。对照组给予常规护理及芦荟外敷,观察组给予常规护理联合复方鲜药外敷。观察2组肿瘤性溃疡伤口愈合面的大小、视觉模拟评分(VAS)、恶臭评分、生存期、生活质量等指标变化情况。结果:护理后,观察组伤口愈合面面积、VAS评分低于对照组,恶臭评分、生存期高于对照组,差异均有统计学意义(P0.05)。护理后1周、2周、3周、5周,观察组QLQ-C30评分均低于同一时间点对照组,差异均有统计学意义(P0.05)。结论:复方鲜药外敷能促进肿瘤性溃疡伤口愈合,减少伤口疼痛和恶臭,提高患者生存期和生活质量。     

现代中医学移植西医学概念的利弊剖析＊

本文全面考察了以统编教材《中医基础理论》为代表的现代中医学大量移植西医学生理、病理概念的状况和严重程度。确认中医学仅仅移植生理、病理两个语词，并未移植西医学两个核心概念原本表达的内涵。中医学将两者作为固有概念使用，严重混淆了中西医学的本质区别，混淆了概念逻辑思维与象思维的本质差异，导致同一学术语境下偷换概念普遍存在。尽快移除生理、病理概念，净化中医学象思维语境，已经成为中医理论研究亟待解决的重大学术问题。
