中成药欧盟注册分析

自2004年起，欧盟和美国分别发布了《传统植物药注册程序指令》和《植物药产品指南》，掀起了中药的新篇章，西方发达国家第一次在法律层面上认可中药作为药品的地位，现通过对欧盟植物药注册法规法律的探讨以及注册成功案例的分析，为我国中成药国际化注册提供一定参考。     

血浊证的诊断标准与疗效评价

血浊理论是从整体观念出发,综合考虑医学、现代科学和社会发展的现状,遵循辨证论治的原则,提出的对疾病防治具有现实意义的一种全新理论。克服传统中医诊断没有定性定量的缺点,制定血浊证规范的证候诊断和临床疗效评价标准,将有效地丰富辨证论治的内容,增强辨证论治的依据,推进中医理论和临床的应用及发展。     

MRI螺旋桨技术在肩袖损伤中的应用

目的观察在高场磁共振螺旋桨(PROPELLER)技术下联合标准"Y"位在临床上对于肩袖损伤的应用效果。方法2018年12月-2019年5月,选择40例具有肩袖损伤相关症状的患者,均采用两种方法进行MRI检查,方法一,采用常规扫描序列:即FSE T2WI,斜冠状面FSE T2WI和斜矢状面FSE T2WI;方法二采用PROPELLER(螺旋桨)技术序列联合标准"Y"位扫描。评价两组患者的肩袖损伤分级程度和肩胛损伤脂肪浸润程度评分比较情况。结果两种方法在肩袖损伤Ⅱ级(χ^2=4.943,P=0.026)、Ⅲ级(χ^2=7.168,P=0.007)比较中,具有显著性差异。两种方法在脂肪浸润程度评分Ⅱ级(t=-4.673,P=0.041)、Ⅲ级(t=-4.442,P=0.046)比较中,也具有显著性差异(P<0.05)结论PROPELLER技术联合标准"Y"位在降低伪影,充分展示肩袖结构等方面更占有优势。     

The burden of herpes zoster disease in Norway

BackgroundNo national vaccination program against herpes zoster (HZ) is currently in place in Norway. We aimed to quantify the burden of medically attended HZ to assess the need for a vaccination program.MethodsWe linked data from several health registries to identify medically attended HZ cases during 2008–2014 and HZ-associated deaths during1996–2012 in the entire population of Norway. We calculated HZ incidences for primary and hospital care by age, sex, type of health encounter, vaccination status, and co-morbidities among hospital patients. We also estimated HZ-associated mortality and case-fatality.ResultsThe study included 82,064 HZ patients, of whom none were reported as vaccinated against HZ. The crude annual incidence of HZ was 227.1 cases per 100,000 in primary healthcare and 24.8 cases per 100,000 in hospitals. Incidence rates were higher in adults aged ≥50 years (461 per 100,000 in primary care and 57 per 100,000 in hospitals), and women than in men both in primary healthcare (267 vs 188 per 100,000), and hospitals (28 vs 22 per 100,000). Among hospital patients, 47% had complicated zoster and 25% had comorbidities, according to the Charlson comorbidity index. The duration of hospital stay (median 4 days) increased with the severity of comorbidities. The estimated mortality rate was 0.18 per 100,000; and in-hospital case-fatality rate was 1.04%.ConclusionsMedically attended HZ poses a substantial burden in the Norwegian healthcare sector. The majority of the zoster cases occurred among adults aged ≥50 years – the group eligible for zoster vaccination – and increased use of zoster vaccination may be warranted, especially among persons with co-morbidities.     

Family nurture intervention alters relationships between preterm infant EEG delta brush characteristics and term age EEG power

ObjectiveFamily Nurture Intervention (FNI) facilitates mother/infant emotional connection, improves neurodevelopmental outcomes and increases electroencephalogram (EEG) power at term age. Here we explored whether delta brushes (DB), early EEG bursts that shape brain development, are altered by FNI and mediate later effects of FNI on EEG.MethodsWe assessed DB characteristics in EEG data from a randomized controlled trial comparing infants with standard care (SC, n = 31) versus SC + FNI (n = 33) at ~35 and ~40 weeks GA.ResultsCompared to SC infants, FNI infant DB amplitude increased more from ~35 to ~40 weeks, and FNI infants had longer duration DBs. DB parameters (rate, amplitude, brush frequency) at ~35 weeks were correlated with power at ~40 weeks, but only in SC infants. FNI effects on DB parameters do not mediate FNI effects on EEG power or coherence at term.ConclusionsDBs are related to subsequent brain activity and FNI alters DB parameters. However, FNI’s effects on electrocortical activity at term age are not dependent on its earlier effects on DBs.SignificanceWhile early DBs can have important effects on later brain activity in preterm infants, facilitating emotional connection with FNI may allow brain maturation to be less dependent on early bursts.     

Inactivated influenza vaccine formulated with single-stranded RNA-based adjuvant confers mucosal immunity and cross-protection against influenza virus infection

Influenza vaccination is considered the most valuable means to prevent and control seasonal influenza infections, which causes various clinical symptoms, ranging from mild cough and fever to even death. Among various influenza vaccine types, the inactivated subunit type is known to provide improved safety with reduced reactogenicity. However, there are some drawbacks associated with inactivated subunit type vaccines, with the main ones being its low immunogenicity and the induction of Th2-biased immune responses. In this study, we investigated the role of a single-stranded RNA (ssRNA) derived from the intergenic region in the internal ribosome entry site of the Cricket paralysis virus as an adjuvant rather than the universal vaccine for a seasonal inactivated subunit influenza vaccine. The ssRNA adjuvant stimulated not only well-balanced cellular (indicated by IgG2a, IFN-γ, IL-2, and TNF-α) and humoral (indicated by IgG1 and IL-4) immune responses but also a mucosal immune response (indicated by IgA), a key protector against respiratory virus infections. It also increases the HI titer, the surrogate marker of influenza vaccine efficacy. Furthermore, ssRNA adjuvant confers cross-protective immune responses against heterologous influenza virus infection while promoting enhanced viral clearance. Moreover, ssRNA adjuvant increases the number of memory CD4⁺ and CD8⁺ T cells, which can be expected to induce long-term immune responses. Therefore, this ssRNA-adjuvanted seasonal inactivated subunit influenza vaccine might be the best influenza vaccine generating robust humoral and cellular immune responses and conferring cross-protective and long-term immunity.
