参黄洗液辅助吻合器痔环切手术治疗混合痔效果及其预后不良早期预警

目的:对参黄洗液辅助吻合器痔环切手术(PPH手术)在混合痔治疗中的效果及其预后不良早期预警的价值进行研究,为临床治疗和不良反应的防治提供数据参考。方法:选取2018年5-12月我院手术治疗的混合痔患者120例为研究对象,采用随机数表法分为观察组和对照组,每组60例。观察组采用参黄洗液辅助PPH手术治疗,对照组PPH术后采用高锰酸钾溶液坐浴治疗。术后辅助治疗20d后就疗效、不良反应及随访3个月的远期疗效进行评价和组间比较,并对观察组预后不良病例的早期反应进行分析。结果:观察组总有效率为96.67%(58/60),高于对照组86.67%(52/60)的总有效率(P<0.05);观察组不良反应发生率为21.67%(13/60),低于对照组31.67%(19/60)的不良反应发生率(P<0.05);观察组病例不良预后发生率为25.00%(15/60),低于对照组33.33%(20/60)的不良预后发生率(P<0.05)。结论:参黄洗液辅助PPH手术在混合痔治疗中具有疗效显著、安全性高、预后良好等优势,临床具有推广价值。     

Rociletinib (CO-1686) enhanced the efficacy of chemotherapeutic agents in ABCG2-overexpressing cancer cells in vitro and in vivo

Overexpression of adenosine triphosphate (ATP)-binding cassette subfamily G member 2 (ABCG2) in cancer cells is known to cause multidrug resistance (MDR), which severely limits the clinical efficacy of chemotherapy. Currently, there is no FDA-approved MDR modulator for clinical use. In this study, rociletinib (CO-1686), a mutant-selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), was found to significantly improve the efficacy of ABCG2 substrate chemotherapeutic agents in the transporter-overexpressing cancer cells in vitro and in MDR tumor xenografts in nude mice, without incurring additional toxicity. Mechanistic studies revealed that in ABCG2-overexpressing cancer cells, rociletinib inhibited ABCG2-mediated drug efflux and increased intracellular accumulation of ABCG2 probe substrates. Moreover, rociletinib, inhibited the ATPase activity, and competed with [¹²⁵I] iodoarylazidoprazosin (IAAP) photolabeling of ABCG2. However, ABCG2 expression at mRNA and protein levels was not altered in the ABCG2-overexpressing cells after treatment with rociletinib. In addition, rociletinib did not inhibit EGFR downstream signaling and phosphorylation of protein kinase B (AKT) and extracellular signal-regulated kinase (ERK). Our results collectively showed that rociletinib reversed ABCG2-mediated MDR by inhibiting ABCG2 efflux function, thus increasing the cellular accumulation of the transporter substrate anticancer drugs. The findings advocated the combination use of rociletinib and other chemotherapeutic drugs in cancer patients with ABCG2-overexpressing MDR tumors.     

基于“肺膀胱别通”浅析针刺肺经穴调治膀胱病

肺与膀胱相通,上为荣养周身以御邪,下以气化排浊调津液,从肺与膀胱关系可以看出,太阳之气与肺气共同卫外,以顾护肌表皮毛,故临床针刺治疗太阳体证时可考虑从肺经穴入手。临床取肺经穴位调治膀胱及其经脉病时,应辨别虚实,采取对应的补泻手法,考虑大部分肺经穴提插、捻转补泻手法不便施展,笔者认为可根据辨证采用更为合适的迎随补泻、徐疾补泻、开阖补泻,即观其脉证,补泻择之。其实不仅肺经穴可治膀胱病,膀胱经穴亦可治肺病,由于肺与膀胱两者经气互通,其中一条经上的穴位可治疗另一条相通经的循行部位或主治方向的疾病。虽然脏腑别通理论在针灸学上具备广泛应用的基础,但因表里经脏腑相互属络关系,更多被提及、应用的是"肺与大肠相关"。容易忽视"肺膀胱别通"在"卫气供给""津液代谢"上的关联。故在临床针刺治疗膀胱病时,可从有别于常规、传统的选经取穴上论治,亦可基于"肺与膀胱相关"以膀胱经穴治肺病,或以两经同取的方式指导针刺治疗相关病证。     

卒中溶栓绿色通道优化研究及实施效果分析

目的探讨卒中溶栓绿色通道的构建、整改对发病到实施溶栓的时间（onset to treatment time,OTT）、院内溶栓时间（door to needle time，DNT）、临床疗效及预后的影响。 方法收集通过绿色通道溶栓患者118例的临床资料，以时间为界分为对照组57例和观察组61例。比较2组OTT、DNT、DNT≤60 min比率、临床疗效、并发症发生情况、美国国立卫生研究院卒中量表（the National Institutes of Health Stroke Scale,NIHSS）评分、Barthel指数（Barthel index，BI）评分、改良Rankin量表（Modified Rankin Scale,mRS）评分等。 结果观察组OTT、DNT短于对照组，DNT≤60 min比例高于对照组（P＜0.01）。经过溶栓治疗72 h后，观察组临床疗效优于对照组，总有效率高于对照组（P＜0.01）。2组总并发症发生率和病死率差异均无统计学意义（P＞0.05）。2组NIHSS评分均呈逐渐降低趋势，观察组NIHSS评分低于对照组，组间、时点间、组间·时点间交互作用差异均有统计学意义（P＜0.01）。2组BI评分均呈逐渐升高趋势，观察组BI评分高于对照组，组间、时点间、组间·时点间交互作用差异均有统计学意义（P＜0.01）。治疗3个月以后，观察组mRS评分明显低于对照组，≤2分比例高于对照组（P＜0.01）。 结论卒中溶栓绿色通道的建立，能够显著缩短OTT、DNT，提高临床疗效，减轻残障程度，取得良好的社会效益。     

The adverse-effect profile of lacosamide

ABSTRACT

Introduction: Lacosamide has been used in epilepsy patients in the United States, Europe and Asia since it was approved by the FDA in 2008. Many patients have benefited from this drug as a new generation of sodium channel blocker. With the worldwide use of this drug, its adverse effects have gradually emerged, especially some rare adverse events.

Areas covered: The present review aims to summarize the adverse effects of lacosamide reported in the literature in recent years to promote the safe clinical application of the drug.

Expert opinion: In more than 10 years of experience in drug usage, adverse reactions of lacosamide have also been gradually discovered. The review showed that lacosamide is safe and effective in antiepileptic treatment, and its common side effects are dizziness, headache, drowsiness, diplopia, and cardiovascular abnormalities. Skin rashes, hematotoxicity and heart damage, psychological symptoms and suicide risk have also been reported and emphasized.
