    阿托伐他汀(ATO)是他汀类药物,用作口服给药的降脂药。ATO是3-羟基-3-甲基-戊二酰-CoA(HMG-CoA)还原酶的可逆合成竞争性抑制剂,因此导致胆固醇合成减少。最近已经证明ATO具有不同的药理作用,这与它的降脂作用无关,并且具有治疗慢性气道疾病的能力。本文综述了ATO作为抗炎的潜力,抗氧化剂,口服或吸入后的抗增殖剂。本文讨论了在与气道中发现的条件相关的条件下使用ATO的优点和缺点。该治疗可潜在地用于支持将ATO配制为用于治疗慢性呼吸道疾病的吸入器。
    Atorvastatin (ATO) is of the statin class and is used as an orally administered lipid-lowering drug. ATO is a reversible synthetic competitive inhibitor of 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase thus leading to a reduction in cholesterol synthesis. It has recently been demonstrated that ATO has different pharmacological actions, which are unrelated to its lipid-lowering effects and has the ability to treat chronic airway diseases. This paper reviews the potential of ATO as an anti-inflammatory, antioxidant, and anti-proliferative agent after oral or inhaled administration. This paper discusses the advantages and disadvantages of using ATO under conditions associated with those found in the airways. This treatment could potentially be used to support the formulating of ATO as an inhaler for the treatment of chronic respiratory diseases.

    慢性粒细胞白血病(CML)是靶向癌症治疗的范例。RT-qPCR是基于血液或骨髓BCR-ABL1减少的监测对酪氨酸激酶抑制剂(TKI)治疗反应的金标准。一些患有CML且BCR-ABL1转录物水平非常低或检测不到的患者可以停止TKI治疗而不发生CML复发。然而,约60%的停止TKI治疗的患者出现白血病快速复发.这增加了对测量残余CML细胞的更灵敏和特异性技术的需要。临床挑战是确定何时停止TKI治疗是安全的。在这篇综述中,我们描述并批判性地评估了CML临床管理的现状,用于监测可测量的残留病(MRD)的不同技术侧重于比较RT-qPCR和进入临床实践的新方法。我们讨论了新方法的优缺点。
    Chronic myeloid leukemia (CML) is the paradigm for targeted cancer therapy. RT-qPCR is the gold standard for monitoring response to tyrosine kinase-inhibitor (TKI) therapy based on the reduction of blood or bone marrow BCR-ABL1. Some patients with CML and very low or undetectable levels of BCR-ABL1 transcripts can stop TKI-therapy without CML recurrence. However, about 60 percent of patients discontinuing TKI-therapy have rapid leukaemia recurrence. This has increased the need for more sensitive and specific techniques to measure residual CML cells. The clinical challenge is to determine when it is safe to stop TKI-therapy. In this review we describe and critically evaluate the current state of CML clinical management, different technologies used to monitor measurable residual disease (MRD) focus on comparingRT-qPCR and new methods entering clinical practice. We discuss advantages and disadvantages of new methods.

    本文的目的是配制瑞舒伐他汀钙和苯磺酸氨氯地平的联合口服剂型,并开发和验证用于常规质量控制测定和制剂体外溶出研究的分析方法。建议的组合制剂已显示与所选赋形剂的相容性,通过FT-IR研究进行了验证。根据ICH指南开发并验证了一种新颖的梯度RP-HPLC方法,该方法适用于从制剂中同时评估瑞舒伐他汀钙和苯磺酸氨氯地平。2.7和6.08分钟的保留时间允许分析大量样品,流动相较少,这使该方法经济。两种药物在不同溶出介质中的溶出曲线令人鼓舞,这使得瑞舒伐他汀钙和苯磺酸氨氯地平的组合制剂在实现患者依从性方面更优越和有效。
    The aim of the paper was to formulate a combined oral dosage form of rosuvastatin calcium and amlodipine besylate and to develop and validate an analytical method to be adopted for both routine quality control assay and in vitro dissolution studies of the formulation. The proposed combination formulation has shown compatibility with the chosen excipients, verified through FT-IR study. A novel gradient RP-HPLC method was developed and validated according to the ICH guideline which was found to be suitable for the simultaneous estimation of rosuvastatin calcium and amlodipine besylate from the formulation. The retention time of 2.7 and 6.08 min allows the analysis of large amount of samples with less mobile phase which makes the method economic. The dissolution profiles of both the drugs in different dissolution medium were encouraging which makes the combination formulation of rosuvastatin calcium and amlodipine besylate superior and effective in achieving patient compliance.

    尽管通过最近引入靶向药物如多激酶抑制剂在晚期肾癌的治疗方面取得了重大改善,这种疾病的长期获益仍然有限,且仍有大量未满足的医疗需求.通过在一小部分患者中诱导持久的反应,癌症免疫疗法显示了其潜力。然而,迄今为止使用的非特异性免疫干预(高剂量)细胞因子与显著的副作用相关.特异性癌症免疫疗法可以通过攻击肿瘤细胞同时保留正常组织来规避这些问题,其中使用多肽疫苗接种是最有前途的策略之一。我们在这里总结了研究IMA901的I期和II期试验的临床和翻译数据。临床获益与针对IMA901肽的可检测T细胞反应的显着关联,以及在治疗患者中令人鼓舞的生存数据,促使开始了一项随机研究,一线晚期RCC的III期对照试验,预计到2015年底生存结果。还讨论了与最近发现的所谓检查点抑制剂的潜在组合策略。
    Despite a major improvement in the treatment of advanced kidney cancer by the recent introduction of targeted agents such as multi-kinase inhibitors, long-term benefits are still limited and a significant unmet medical need remains for this disease. Cancer immunotherapy has shown its potential by the induction of long-lasting responses in a small subset of patients, however, the unspecific immune interventions with (high dose) cytokines used so far are associated with significant side effects. Specific cancer immunotherapy may circumvent these problems by attacking tumor cells while sparing normal tissue with the use of multi-peptide vaccination being one of the most promising strategies. We here summarize the clinical and translational data from phase I and II trials investigating IMA901. Significant associations of clinical benefit with detectable T cell responses against the IMA901 peptides and encouraging survival data in treated patients has prompted the start of a randomized, controlled phase III trial in 1st line advanced RCC with survival results expected toward the end of 2015. Potential combination strategies with the recently discovered so-called checkpoint inhibitors are also discussed.
