中西医结合治疗慢性支气管炎急性发作临床观察

目的研究中西医结合治疗慢性支气管炎急性发作的效果。方法选取2018年11月-2019年11月就诊的60例慢性支气管炎急性发作期患者作为此次研究的对象,其中2018年11月-2019年4月到院的30例患者归为对照组,予以常规西医给药治疗;2019年4月-2019年11月到院的30例患者归为观察组,在对照组的基础身上予以清化止咳汤治疗,对比2组的临床疗效、不良症状改善的时间变化情况及不良反应的发生情况。结果观察组患者的临床总有效率(93.33%)显著高于对照组(73.33%)(P<0.05)。观察组患者不良症状改善的时间均短于对照组(P<0.05)。观察组患者的不良反应发生率(6.67%)显著低于对照组(26.67%)(P<0.05)。结论予以慢性支气管炎急性发作期患者中西结合治疗,能够有效的减轻其临床症状,使不良症状能够更快速的得到改善,并且减少不良反应的发生现象,进一步提高患者身体健康的恢复。     

中西医结合护理干预妊娠晚期合并急性单纯性阑尾炎患者的临床观察

目的:探讨中西医结合护理干预妊娠晚期合并急性单纯性阑尾炎的临床疗效。方法:将2017 年9 月—2018 年12月于我院接受中西医结合保守治疗的31 例妊娠晚期合并急性单纯性阑尾炎患者作为研究对象，按随机数表法随机分为中西医结合护理组(观察组16 例)与常规护理组(对照组15 例)，对照组采取常规护理措施，观察组在对照组的基础上增加中西医结合护理措施，对比两组患者的临床疗效。结果:观察组患者的心理状态变化、新生儿体质状况以及临床疗效等指标等情况均明显优于对照组，且组间对比差异显著有统计学意义(P ＜ 0.05)。结论:中西医结合护理对妊娠晚期合并急性单纯性阑尾炎有较好的临床效果，可减少、甚至避免孕妇因合并急性阑尾炎而造成的打击和创伤。     

Acute generalized exanthematous pustulosis due to ceftriaxone: Report of a pediatric case with recurrence after positive patch test

Acute generalized exanthematous pustulosis (AGEP) is seen uncommonly in children and sometimes shows atypical clinical features in this population. Patch testing can be used effectively in children for the confirmation of the culprit drug in cases of multiple drug use. Here, we report a rare, pediatric case of ceftriaxone‐induced AGEP confirmed by patch testing with subsequent recurrence of the skin eruption.     

鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗新生儿急性呼吸窘迫综合征疾病的临床应用研究

目的:分析鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗ARDS(新生儿急性呼吸窘迫综合征)疾病的临床应用效果。方法:纳入病例是2017年5月—2019年11月收治的104例ARDS新生儿,随机平均分为两组。参照组52例采纳CPAP(持续气道正压通气通气)治疗,实验组52例采纳NIPPV+布地奈德雾化治疗,对比两组呼吸机通气时间、用氧时间、住院时间、血气指标以及并发症发生情况。结果:实验组呼吸机通气时间、用氧时间、住院时间均明显短于参照组,差异有统计学意义P<0.05;实验组治疗3 d后PaCO2明显低于参照组,实验组治疗3 d后PH以及PaO2明显高于参照组,差异有统计学意义P<0.05;实验组并发症发生率(3.85%,2/52)明显低于参照组(21.15%,11/52),差异有统计学意义P<0.05。结论:NIPPV+布地奈德雾化可有效缩短ARDS患者机械通气时间,改善血气指标,降低并发症发生率,值得借鉴。     

依维莫司联合全反式维甲酸逆转急性早幼粒细胞白血病细胞耐药的研究

目的探讨依维莫司联合全反式维甲酸(简称维甲酸)逆转急性早幼粒细胞白血病(APL)细胞株NB4-R1耐药的作用。方法应用CD11b染色流式细胞术及硝基四唑氮蓝(NBT)还原实验检测两药联合应用对细胞分化的影响, 流式细胞术检测细胞周期情况, Annexin V/PI双染色检测细胞凋亡情况, 蛋白质印迹法检测自噬相关蛋白微管结合蛋白轻链3(LC3)、Beclin 1及早幼粒白血病-维甲酸受体融合蛋白(PML-RARα)、磷酸化核糖体S6激酶(P-P70S6K)、磷酸化4E结合蛋白1(P-4E-BP1) 等表达水平。结果与维甲酸组比较, 联用组能诱导耐药细胞株NB4-R1细胞的分化, 并将细胞增殖阻止在G ₁期而对细胞凋亡无明显影响。100 nmol/L依维莫司组、1μmol/L维甲酸组、联用组、对照组NB4-R1细胞培养48 h后分化百分率分别为(2.29±0.57)%、(17.06±2.65)%、(54.47±4.91)%、(2.54±0.53)%; 处于G ₁期的细胞百分率分别为(35.20±11.97)%、(33.54±6.25)%、(53.70±8.73)%、(27.40±6.01)%; 四组细胞凋亡细胞百分率分别为(2.30±0.14)%、(2.25±0.21)%、(2.40±0.28)%、(1.95±0.07)%。与维甲酸组比较, 联用组mTOR信号通路下游的P70S6K、4E-BP1分子磷酸化水平下降, LC3-II和Beclin 1的表达上调, 且能部分降解融合蛋白PML-RARα。 结论依维莫司联合维甲酸能诱导NB4-R1细胞分化, 且能阻滞细胞周期而不致细胞凋亡, 其机制可能与依维莫司联合维甲酸抑制mTOR信号通路激活自噬作用从而降解PML-RARα蛋白有关。     

Absence of FGFR3–TACC3 rearrangement in hematological malignancies with numerical chromosomal alteration

FGFR–TACC, found in different tumor types, is characterized by the fusion of a member of fibroblast grown factor receptor (FGFR) tyrosine kinase (TK) family to a member of the transforming acidic coiled-coil (TACC) proteins. Because chromosome numerical alterations, hallmarks of FGFR–TACC fusions are present in many hematological disorders and there are no data on the prevalence, we studied a series of patients with acute myeloid leukemia and myelodysplastic syndrome who presented numerical alterations using cytogenetic traditional analysis. None of the analyzed samples showed FGFR3–TACC3 gene fusion, so screening for this mutation at diagnosis is not recommended.     

Clinical Guidance for the Management of Patients with Urothelial Cancers During the COVID-19 Pandemic – Rapid Review

The current COVID-19 pandemic presents a substantial obstacle to cancer patient care. Data from China as well as risk models suppose that cancer patients, particularly those on active, immunosuppressive therapies are at higher risks of severe infection from the illness. In addition, staff illness and restructuring of services to deal with the crisis will inevitably place treatment capacities under significant strain. These guidelines aim to expand on those provided by NHS England regarding cancer care during the coronavirus pandemic by examining the known literature and provide guidance in managing patients with urothelial and rarer urinary tract cancers. In particular, they address the estimated risk and benefits of standard treatments and consider the alternatives in the current situation. As a result, it is recommended that this guidance will help form a framework for shared decision making with patients. Moreover, they do not advise a one-size-fits-all approach but recommend continual assessment of the situation with discussion within and between centres.
