青藤碱及其新剂型治疗类风湿性关节炎的研究进展

类风湿性关节炎是一种长期性、顽固性、致残性的自身免疫性疾病。目前,临床上治疗类风湿性关节炎的药物主要包括非甾体类抗炎药、糖皮质激素、免疫调节剂等,但长期使用易产生恶心、胃肠道不适、肝损伤等不良反应。青藤碱是源于青风藤中的一种有效成分,具有镇痛、抗炎、抗菌、降血压等药理作用,临床可用来治疗类风湿性关节炎等疾病。目前,青藤碱尚存在半衰期短、生物利用度低、给药剂量大等不足之处,青藤碱新剂型的开发有望为类风湿性关节炎的治疗提供新的思路。基于近年来青藤碱的研究进展,对青藤碱治疗类风湿性关节炎的基本性质、临床应用、药理作用和新剂型研究进行了综述,为青藤碱新剂型开发及临床应用提供参考。

新形势下中药新药研发的思路与策略

中药新药研发中的中药创新研发是中药产业发展和科技进步的源泉,是关乎国计民生、解决临床重大疾病预防与治疗重大问题的关键途径。自1985年我国实行新药审评办法以来,中药新药研发通过多年的努力,取得了显著的进展。2020年3月30日,国家市场监督管理总局公布新的《药品注册管理办法》,同年10月,国家药品监督管理局发布了《中药注册分类及申报资料要求》,对中药新药研发提出了新的要求,也展示了新的发展机遇。基于中药新药的临床需求和市场环境以及新的中药注册要求,针对中药创新研发及成果转化过程中存在的关键瓶颈问题,提出新形势下中药新药研发的总体思路、研发策略和技术路径,以期为新形势下的中药新药研发提供参考。     

Current Physiotherapy Practice of New Referrals to a Regional Paediatric Cystic Fibrosis Service

This paper reviews the physiotherapy practice and management of 85 cystic fibrosis patients referred to a Regional unit for comprehensive assessment. Following assessment, recommendations were made to the patients and referring units. Physiotherapy treatment was found to be sub-optimal in several areas. We suggest that, on the basis of our results, assessment/review at a Regional Cystic Fibrosis Centre would be beneficial to cystic fibrosis patients.     

我国中药材新品种保护与DUS测试指南研制现状

我国植物新品种保护工作起步较晚,特别是中药材植物新品种保护相对较弱,特异性、一致性、稳定性(DUS)测试指南的研制相对落后。中华人民共和国农业农村部颁布的191个种(属)植物保护名录中直接涉及中药材的仅有20个种(属)。目前,中药材植物新品种保护申请量为125件,授权16件。通过概述我国中药材新品种选育进展、统计中药材植物新品种权申请和授权情况,论述我国中药材新品种保护及DUS测试指南研制现状;结合农业和林业作物新品种保护现状,分析我国中药材植物新品种保护存在数量稀少、中药材植物DUS测试指南研制质量不高等问题的原因。建议我国中药材育种专家提高知识产权保护意识,进而对我国中药材植物DUS测试指南研制方向进行展望。     

Biomechanical evaluation of a new design titanium miniplate for the treatment of mandibular angle fractures

The optimal management of mandibular angle fractures remains controversial. The aim of this experimental study was to test the stability and resistance to mechanical force of a new titanium miniplate design. Thirty fresh sheep hemimandibles, sectioned at the angle region, were used to evaluate two plating techniques. One group received fixation via a new design single non-compression titanium miniplate and the second group via a six-hole straight non-compression titanium miniplate. A custom-made biomechanical test model was used for the samples. Each hemimandible was subjected to compressive and tensile forces using an Instron machine. The biomechanical forces (N) that caused 4-mm displacement or fixation loosening were compared. Comparison between the groups showed that fixation with the new design miniplate had more resistance to lateral compression forces than with a six-hole straight miniplate (P < 0.009). Moreover, the new design miniplate fixation displayed more resistance to vertical compression and tensile forces (P > 0.46 and P > 0.61, respectively). The study demonstrated that mandibular fracture fixation with the new design non-compression titanium miniplate offered greater resistance to lateral displacement forces and may also provide increased resistance to vertical compressive and tensile forces than a conventional six-hole straight miniplate.     

新入职护士关怀能力与关怀行为状况及相关性研究

目的了解新入职护士关怀能力和对关怀行为的感知状况,分析两者间相关关系,为培养新护士关怀能力及关怀行为提供依据。方法采用关怀能力评价量表（CAI）和关怀维度测量表（CDI）对171名新入职护士进行调查。结果关怀能力、关怀行为感知的总分分别为199.23±20.14、85.49±10.97;CAI与CDI呈正相关（r=0.54,P〈0.01）。结论新入职护士关怀能力处于较低水平,关怀行为感知处于中上等水平,两者间关系密切。应对新入职护士加强整体护理内涵及关怀行为培训,增强新入职护士对关怀行为的感知力,提升关怀能力。     

Amhezole,A Novel Fungal Secondary Metabolite from Aspergillus terreus for Treatment of Microbial Mouth Infection

Bio‐guided fractionation of Aspergillus terreus extract leads to isolation of a novel terpenoidal secondary metabolite. The isolated compound and the total alcoholic extract of Aspergillus terreus showed a remarkable activity against microbial mouth infections; namely, Candida albicans, Lactobacillus acidophilus, Streptococcus gordonii, and S. mutan. Moreover, the Minimum Inhibitory Concentration of the isolated compound was determined and showed low values. The combination of each of the alcoholic extract of A. terreus and the isolated compound Coe‐Comfort tissue conditioner inhibited the growth of Candida albicans at concentrations of 500 and 7.81 µg/mL, respectively, Lactobacillus acidophilus at concentrations of 250 and 7.81 µg/mL, respectively, Streptococcus gordonii at concentrations of 1000 and 62.50 µg/mL, respectively, and S. mutans at concentrations of 1000 and 125 µg/mL, respectively. The oral dosing of the extract and the isolated compound did not show any significant effect on the activity of alanine aminotransferase, aspirate aminotransferase, and the levels of blood urea and serum creatinine.
