紫草剂量与用药时间对药物流产临床效果的影响

本文对药物流产时在不同时间加用不同剂量的紫草对药物流产效果的影响进行探索。紫草的加用时间为米索前列醇 (简称米索 )应用前 3d、后 3d及前后共 6 d,剂量分别为 5 0 g、75 g和 1 0 0 g。 1 35 0例早孕妇女分成 9个研究组进行观察。结果表明 :在米索应用前 3d和前后 6 d加用紫草效果较米索应用后 3d加用紫草在完全流产率和出血时间两方面效果明显改善 (P均 <0 .0 5 )。紫草用量 5 0～ 1 0 0 g时流产效果与紫草剂量无明显相关。因此我们认为药物流产时在应用米索前紫草与米非司酮同时应用效果较好 ,剂量以5 0 g较为合理

Anticoccidial effects of Ageratum conyzoides

Ageratum conyzoides (Asteraceae) is folklorically used to treat diseases associated with bleeding. A study was conducted to determine the efficacy of Ageratum conyzoides in treating caecal coccidiosis of broilers. Acute toxicity test was done using thirty 28 days old broiler chicks which were divided into six groups of five birds each. The birds were given 250–3000 mg of extract/kg bodyweight orally. Group VI received equal volumes of distilled water. The birds were observed for 24 h for signs of toxicity. Twenty-five growing broilers were divided into five groups of five birds each. At 35 days of age, birds in groups A to D were each infected orally with 8000 oocysts of Eimeria tenella. Fifteen days post-infection, groups A and B were treated with 500 and 1000 mg/kg of the extract, respectively. Group C received Amprolium in drinking water as 0.012 and 0.006% solutions for 7 days, respectively. Groups D and E were the negative and positive controls. No signs of toxicity were observed during the acute toxicity test. The faecal oocyst per gram of faeces decreased steadily in all the treatment groups until it became zero. The packed cell volumes, weight and red blood cell counts of the treated birds were significantly (P < 0.05) higher than those of the infected untreated control. This confirms its ethnoveterinary use in the treatment of coccidiosis.     

针药联合治疗早发性卵巢功能不全疗效的Meta分析

目的：系统评价针药联合治疗早发性卵巢功能不全的疗效。方法：检索PubMed、Cochrane Library、Embase、中国学术期刊数据库（China Science Periodical Database,CSPD）、国家知识基础设施数据库（China National Knowledge Infrastructure,CNKI）、中文科技期刊数据库（Chinese Citation Database,CCD）、中国生物医学文献（China Biology Medicine,CBM）等数据库关于针药联合治疗早发性卵巢功能不全的随机对照试验（RCT）,检索时间为2000年1月至2020年1月。由2名研究者独立筛选文献并进行质量评价后,使用RevMan 5.3软件进行Meta分析。结果：共检索到858篇文献,最终纳入14项RCT,其中包括962例患者。Meta分析显示,针药联合治疗早发性卵巢功能不全有效率高于单纯西药治疗（RR=1.16,95%CI为1.09～1.24,P<0.000 01）。针药联合治疗早发性卵巢功能不全患者血清FSH水平优于单纯西药治疗（SMD=-0.82,95%CI为-1.25～-0.40）,P<0.000 01）。结论：针药联合治疗早发性卵巢功能不全比单独使用西药具有更好的临床疗效。但由于纳入研究的文献质量偏低,该结论还有待更多高质量大样本RCT验证。     

沙棘属药用植物亲缘学研究进展

沙棘作为一种既有经济效益又有社会效益的药食同源特色植物,素有“天然维生素宝库”“营养保健来源”等美称。早在公元8世纪已经发现沙棘有祛痰止咳,消食化滞,活血散瘀之效。研究表明沙棘属植物中含有黄酮类、萜类、挥发油类以及甾体类化合物,此外还含有大量的维生素、多糖、脂肪酸和人体必需的微量元素等生物活性物质,对心血管系统、血液系统、消化系统、免疫系统以及呼吸系统等方面的疾病有良好治疗作用。为了更深入的探讨沙棘属亲缘关系,现总结归纳了沙棘属植物的传统药用价值、化学成分及现代药理作用,并在此基础上寻找三者之间的相关性,为有效开发及合理利用本属资源提供依据。

Neuronutrient impact of Ayurvedic Rasayana therapy in brain aging

Ayurveda is the oldest system of Medicine in the world, its antiquity going back to the Vedas. It adapts a unique holistic approach to the entire science of life, health and cure. The areas of special consideration in Ayurveda are geriatrics, rejuvenation, nutrition, immunology, genetics and higher consciousness. The Ayurvedic texts describe a set of rejuvenative measures to impart biological sustenance to the bodily tissues. These remedies are called Rasayana which are claimed to act as micronutrients. Some of these Rasayanas are organ and tissue specific. Those specific to brain tissue are called Medhya Rasayana. Such Rasayanas retard brain aging and help in regeneration of neural tissues besides producing antistress, adaptogenic and memory enhancing effect. In addition to the long tradition of textual and experience-based evidence for their efficacy, certain recent studies conducted on these traditional remedies on scientific parameters have shown promising results which have been reviewed in this paper for providing lead for further studies. The popular Medhya Rasayanas are Ashwagandha (Withania somnifera Dunal), Brahmi (Bacopa monnieri Linn), Mandukaparni (Centella asiatica Linn) and Sankhapuspi (Convolvulus pluricaulis Chois).     

A review of the efficacy of traditional Iranian medicine for inflammatory bowel disease

The etiology of inflammatory bowel disease(IBD) is not yet known,but many factors such as defects in the immune system,oxidative stress,microbial content in the gastrointestinal tract,nuclear factor(NF)-κB,nitric oxide(NO),cyclooxygenase-2(Cox-2),and leukotriene B4(LB4) are thought to play a role in its pathogenesis.In traditional Iranian medicine(TIM),several medicinal plants are thought to be effective for the treatment of IBD.In this study,information on all of these remedies were derived from all available old sources such as documents or notes and books and were added to the information derived from modern medical databases covering all in vitro,in vivo and clinical trials.For some of these plants,only one or two mechanisms of action have been found such as in Cassia fistula,Lepidium sativum,and Bunium persicum.However,for some plants various mechanisms of action are known.For example,Commiphora mukul is effective in IBD due to its immunomodulatory,antioxidant,and antibacterial properties and it decreases NF-κB,NO and Cox-2.Another herb,Plantago ovata,has immunomodulatory,antioxidant,anti-inflammatory and wound healing activities and decreases NO and LB4.Considering the mechanisms of action of these plants,the combination of some of them may be useful because of their many mechanisms of action such as Pistacia lentiscus,Bunium persicum,Solanum nigrum,Plantago ovata,Boswellia,Solanum nigrum,Plantago ovata and Commiphora mukul.For some of the herbal products used in TIM such as oleogum resin from Commiphora myrrha,seeds of Ocimum basilicum,seeds of Linum usitatissimum,gum resin of Dracaena cinnabari,seeds of Plantago major,seeds of Lallementia royleana,and seeds of Allium porrum,there is no or not enough studies to confirm their benefits in IBD.It is suggested that an evaluation of the effects of these plants on different aspects of IBD should be performed.
