抗急性痛风性关节炎天然产物药理研究进展

通过查阅近几年有关天然产物及其有效成分抗急性痛风性关节炎的药理作用及其机制相关研究的文献报道,围绕尿酸盐结晶所致急性痛风性关节炎动物模型的发病机制,对天然产物及其有效成分抗急性痛风性关节炎作用靶点和药理作用机制进行文献整理、分析和归纳。研究表明,抗急性痛风性关节炎的天然产物有效成分主要有黄酮类、生物碱类、多酚类、皂苷类、香豆素类等,通过抗炎、镇痛、抑制相关炎症介质的释放及其信号通路、抗氧化等作用机制及多个药物作用靶点发挥抗急性痛风性关节炎的作用。治疗急性痛风性关节炎的西药作用靶点较单一,存在较严重副作用,不利于控制急性痛风性关节炎的发复发作。中医运用天然药物防治急性痛风性关节炎拥有上千年历史和经验,与西药相比,抗急性痛风性关节炎天然药物具有多靶点,低毒副作用的优势,近年来越来越多的科研工作者运用实验药理学和分子生物学方法来研究天然产物及其有效成分抗急性痛风性关节炎的作用,并取得喜人的研究成果。

三七总皂苷抑制大鼠全脑缺血后海马CA1区神经元凋亡及其机制研究

目的探讨三七总皂苷(TSPN)抑制大鼠全脑缺血后海马CA1区神经元的凋亡作用及其相关机制。方法采用四血管阻断法制备大鼠全脑缺血模型,缺血后30 min再灌注;大鼠分成假手术组、模型组和TSPN组。TSPN组ip不同剂量(25、50、75、100 mg/kg)TSPN。再灌注第14天,通过海马CA1区尼氏染色和大鼠的生存率确定TSPN发挥神经保护作用的最佳剂量。对模型组和最佳剂量TSPN组大鼠在不同再灌注时间点(1、3、7、14 d)进行神经功能评分,采用免疫组化法观察CA1区Caspase-3、Bcl-2、Bax的阳性细胞密度,并采用免疫印迹技术检测Caspase-3、Bcl-2、Bax蛋白在海马的表达水平。结果 75 mg/kg TSPN组大鼠生存率为100%,CA1区神经元密度显著高于模型组和其他剂量TSPN组(P0.05);TSPN(75 mg/kg)组神经功能评分显著少于模型组(P0.01);TSPN(75 mg/kg)组CA1区Caspase-3阳性细胞密度在全脑缺血第7、14天显著低于模型组(P0.001);20 000的Caspase-3第3、7、14天的蛋白水平及17 000的Caspase-3在第7、14天蛋白水平均显著低于模型组(P0.001);TSPN(75 mg/kg)组CA1区Bcl-2阳性细胞密度及蛋白水平在第7、14天高于模型组(P0.001),而Bax阳性细胞密度第7、14天低于模型组(P0.001),TSPN组第3、7、14天海马Bax蛋白水平显著低于模型组(P0.001);TSPN组Bcl-2和Bax阳性细胞及蛋白水平的比值在第7、14天显著高于模型组(P0.001)。结论 TSPN可通过上调Bcl-2和Bax阳性细胞和蛋白水平的比值,减少Caspase-3的活化而抑制全脑缺血后大鼠海马CA1区神经元的凋亡。     

青叶胆组织培养条件优化及不同交配方式子代植株再生能力比较研究

目的优化青叶胆Swertia mileensis组织培养快速繁殖技术,同时比较不同交配方式后代植株的再生能力,从而探讨青叶胆片断化居群繁殖保障机制。方法以自交、近交、远交和自然结实种子为材料,相同方法消毒后接种于空白MS培养基上,60 d后统计各组萌发率;在此基础上,以各组无菌苗带节茎段为外植体,采用正交试验考察不同来源外植体在添加不同植物激素及质量浓度组合的MS培养基中诱导愈伤组织及丛芽分化能力。结果自交、近交、远交和自然结实种子萌发率之间无显著性差异(P0.05);适宜的愈伤组织诱导培养基为MS+ZT 0.5 mg/L+2,4-D 0.05 mg/L,在此培养条件下,自交、近交、远交和自然结实种子苗带节茎段愈伤组织诱导率分别达100%、96.67%、96.55%和96.29%,各组间无显著性差异;适宜的丛芽发生培养基为MS+BA 2.0 mg/L+KT 0.1 mg/L+NAA 1.0 mg/L,4种来源不同的愈伤组织丛芽分化率均为100%;生根则在1/2 MS+NAA 1.0 mg/L中进行,4种来源不同的试管苗生根率均为100%,生根苗在生长势上亦无明显差别。结论优化的青叶胆组织培养快速繁殖技术,为保护其野生资源、种苗繁殖提供了有效途径,同时从植物生理学角度初步推测青叶胆近交的获益可以补偿与近交相伴的适合度损失,其后代植株在再生能力方面与异交无显著差异。     

Efficacy of the herbal formula of Foeniculum vulgare and Rosa damascena on elderly patients with functional constipation: A double-blind randomized controlled trial

BackgroundConstipation is a common chronic bowel disorder with an incidence of more than 50% in the elderly population. Complementary and alternative medicine is a cost-effective and satisfactory treatment for constipation used widely by the elderly.ObjectiveThis study evaluates the efficacy of an herbal formula made from Foeniculum vulgare Mill. and Rosa damascena for the treatment of constipation in an elderly population and consequent changes to their quality of life.Design, setting, participants and interventionThis double-blind randomized active controlled clinical trial, with parallel group allocation ratio of 1:1, was conducted in a referral clinic in Afzalipour Hospital, affiliated to Kerman University of Medical Sciences in Kerman, Southeastern Iran. Individuals over 60 years of age, diagnosed with functional constipation (based on the Rome IV criteria), were included in this study. Participants received a sachet of 10 g F. vulgare and R. damascena (herbal formula group) or polyethylene glycol 4000 (PEG 4000 group) with a glass of warm water two times a day for 4 weeks and were followed up for 4 additional weeks.Main outcome measuresConstipation severity, stool consistency, and the quality of life were used as the primary outcomes. Drug side effects were used as a secondary outcome. The outcomes were assessed using the Constipation Assessment Scale, the Bristol Stool Form Scale, and the Patient Assessment of Constipation Quality of Life questionnaire.ResultsA total of 25 participants in each group completed the four-week treatment cycle and the eight-week follow-up. At the end of the four-week treatment cycle, all clinical outcomes had significant improvements in both groups (P < 0.05). The analysis of constipation severity (P < 0.001), stool consistency (P < 0.001), and the quality of life (P < 0.001) showed significant improvements with fewer side effects (mild diarrhea) and a longer duration of symptom relief in the herbal formula group compared to the PEG 4000 group.ConclusionAlthough both interventions significantly improved the treatment outcomes, constipation severity, stool consistency and the quality of life were improved more effectively by the herbal formula than by PEG 4000; however, the mechanism of action is not yet understood.Trial registrationThis trial was registered in the Iranian Registry of Clinical Trials (IRCTID: IRCT20200108046056N1).

经方薯蓣丸对变应性鼻炎大鼠血清IgE、IL-4含量的影响

目的：探讨经方薯蓣丸对变应性鼻炎（AR）大鼠模型的疗效及对血清IgE、IL-4含量的影响。方法60只大鼠随机分为正常对照组、模型组、辛芩颗粒组、经方薯蓣丸高、中、低剂量组（3.2,1.6,0.8g/kg）,每组10只。对除正常对照组外的5组大鼠采用卵清蛋白（OVA）致敏和激发进行造模,造模成功后给药,经方薯蓣丸高、中、低剂量组分别采用薯蓣丸浓缩水煎液灌胃,辛芩颗粒组给予辛芩颗粒灌胃。治疗14d后采用酶联免疫吸附试验（ELISA法）检测各组大鼠血清IgE、IL-4含量。结果造模后各组大鼠行为学评分均明显高于正常对照组（P＜0.01）;治疗后各组行为学评分及血清IgE、IL-4含量较模型组均有降低（P＜0.05）;与辛芩颗粒组相比,中剂量组血清IgE、IL-4含量明显降低,差异有统计学意义（P＜0.05）。结论经方薯蓣丸对AR大鼠模型的疗效显著,其作用机理可能与降低血清IgE、IL-4含量有关。
