This study aimed to detect associations of bile acid profile with white matter hyperintensity and quantify the risk of cerebral small vessel disease with high level of bile acid among cognitively normal individuals. All data were obtained from the patients with Alzheimer’s disease neuroimaging initiative with a 10 y follow-up. Multivariate linear regressions were performed with variable selection using the least absolute shrinkage and selection operator method and the linear mixed model was used to analyze longitudinal relationship between non-zero coefficient variables and white matter hyperintensity volume. Four predictors (age, deoxycholic acid, glucose, total intracranial volume) were identified by least absolute shrinkage and selection operator regression analysis and multivariate linear regressions. Age (p value<0.001, mean difference, 1.03 cm 3 [95 % interval: 1.02, 1.04]) and deoxycholic acid (p value<0.05, mean difference, 1.05 cm 3 [95 % confidence interval: 1.00, 1.10]) were significantly associated with white matter hyperintensity. When divided into two groups by the median deoxycholic acid level (1.38 µM), participants with higher deoxycholic acid levels had a higher white matter hyperintensity volume at the 4 th y than those with lower deoxycholic acid levels (mean difference, 0.1 points [95 % confidence interval: -0.17, -0.03]; p<0.05). We found that increased deoxycholic acid levels may lead to the progression of white matter hyperintensity, which suggest that higher deoxycholic acid burden may play a possible role in the pathogenesis of cerebral small vessel disease in cognitively normal older adults. Besides, the study indicates a possible role for inflammation in the pathogenesis of cerebral small vessel disease.

The purpose of this study is to evaluate the efficacy of the Chinese herbal ointment Qingluo San in preventing phlebitis in patients with peripheral venous catheters. We conducted a single-center randomized controlled trial, in which 127 eligible patients were assigned randomly to one of two groups; the experimental group or the control group. The degrees of pain intensity and phlebitis were measured at baseline, 24 h, 48 h and 72 h. Demographic information (age, gender, body mass index) and phlebitis sites, catheter dwell time, hemoglobin and white blood cells were obtained from all patients. Compared with the control group, the experimental group showed significantly lower incidence of phlebitis and pain intensity at 24 h, 48 h and 72 h after intervention. However, there were no significant differences about the demographic information (age, gender, body mass index) and phlebitis sites, catheter dwell time, hemoglobin and white blood cells between these two groups. In patients with peripheral venous catheters, external treatment with Qingluo San was an effective method for decreasing the incidence of phlebitis.
本研究的目的是评价中药软膏清络散对外周静脉置管患者静脉炎的预防作用。我们进行了一项单中心随机对照试验,将127名符合条件的患者随机分为两组;实验组和对照组。在基线、24小时、48小时和72小时测量疼痛强度和静脉炎程度,并获取所有患者的人口统计学信息(年龄、性别、体重指数)、静脉炎部位、导管停留时间、血红蛋白和白细胞。与对照组相比,实验组在干预后24 h、48 h、72 h静脉炎发生率和疼痛强度均明显降低。两组患者的人口统计学信息(年龄、性别、体重指数)、静脉炎部位、置管时间、血红蛋白、白细胞等差异均无统计学意义。外置静脉导管患者外置清络散治疗是降低静脉炎发生率的有效方法。

In Ayurveda, single or multiple herbs are used as medication for various ailments. Depression is often manifesting with various symptoms at the behavioral, psychological and physiological levels. Therefore, the investigation for therapeutic alternative is important. Oxidative stress has shown important biochemical aspects in the depression. This study evaluated effect of natural antioxidant on antidepressant activity of polyherbal formulation on the performance of male mice. Mice were given orally polyherbal formulation without antioxidant and with antioxidant daily for 7 d and then subjected to forced swim test and tail suspension test. After 1 w treatment, both polyherbal formulation significantly reduced immobility time in forced swim test and tail suspension test compared with vehicle treated control group. The immobility time in tail suspension test of polyherbal formulation without antioxidant and with antioxidant was found to be 151.17±4.46 s and 116.33±8.84 s respectively. The immobility time in tail suspension test of polyherbal formulation without antioxidant and with antioxidant was found to be 137.17±5.93 s, 113.50±5.40 s respectively. These results indicate that the antidepressant when given along with antioxidant in mice it gives significant antidepressant effect. The experimental results suggest that the intake of antioxidant may help in reducing the symptoms of depression, via supplementation of antioxidant.

Cancers are the uncontrolled growth of cells or tumors, and it is one of the leading causes of death all over the world. Currently, available synthetic drugs such as cisplatin, doxorubicin and fluorouracil are reported to have notable side effects in living tissues (skin irritations, dry and cracked skin, and mouth sores). So researchers are scrutinizing for alternative medications to overcome these side effects. Plants are one of the vital sources of alternative medicines with less toxicity and may overcome these side-effects of synthetic drugs. The study evaluated cytotoxicity and antioxidant potential on methanolic and aqueous extract of Pittosporum dasycaulon leaves. In the present study of cytotoxicity, the selected extracts were screened against two cancer cell lines (human liver cancer cells and Lymph cancer cell-Dalton's lymphoma ascites ascites). Two normal cells, intestinal epithelial-6, and Rat spleen were used to test cytotoxicity by using the trypan blue exclusion method and 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay. The antiradical activity was also evaluated with its half maximal inhibitory concentration. The content of total phenolic, flavonoid and saponins was also estimated. The present study displayed leaves methanolic extract found to have a significant rate of cell death against cancer cell lines (Dalton's lymphoma ascites and human liver cancer cells) with lethal concentration 50 values ranging from 8.21±0.3 to 55.65±0.11 µg/ml. However, the same extract had very less cytotoxicity even in higher doses against non-cancerous intestinal cell lines (intestinal epithelial-6) and rat spleen cell lines ranging from 389.50±0.6 to 1800.00±0.1 μg/ml. The quantitative analysis of leaf methanolic extract showed a high level of saponins and phenolic compounds. Therefore, leaves of Pittosporum dasycaulon Miq are a promising candidate for natural antioxidant as well as anticancer components. Hence, further extensive study urges to evaluate the mechanism as well as to investigate of individual components responsible for cytotoxicity and antiradical potential.
癌症是细胞或肿瘤不受控制的生长,它是世界上导致死亡的主要原因之一。目前,据报道,现有的合成药物如顺铂、阿霉素和氟尿嘧啶对活体组织有明显的副作用(皮肤刺激、皮肤干燥和皲裂、口腔溃疡)。因此,研究人员正在仔细研究替代药物来克服这些副作用。植物是毒性较小的替代药物的重要来源之一,可以克服合成药物的这些副作用。本研究评价了油松叶醇提物和水提物的细胞毒性和抗氧化活性。在目前的细胞毒性研究中,所选提取物对两种癌细胞系(人肝癌细胞和淋巴癌细胞-道尔顿淋巴瘤腹水)进行了筛选。采用台番蓝排斥法和3-(4,5 -二甲基噻唑-2)- 2,5 -二苯基溴化四唑试验检测正常细胞肠上皮-6和大鼠脾脏的细胞毒性。并以其最大抑制浓度的一半来评价其抗自由基活性。测定了总酚、类黄酮和皂苷的含量。本研究发现,叶甲醇提取物对癌细胞(道尔顿淋巴瘤腹水细胞和人肝癌细胞)具有显著的细胞死亡率,致死浓度50值为8.21±0.3 ~ 55.65±0.11µg/ml。在389.50±0.6 ~ 1800.00±0.1 μg/ml范围内,相同的提取物对非癌性肠细胞株(肠上皮-6)和大鼠脾细胞株的细胞毒性很小。定量分析表明,叶甲醇提取物中皂苷和酚类化合物含量较高。因此,皮孢叶是一种很有前途的天然抗氧化剂和抗癌成分。因此,进一步的研究迫切需要评估其机制,并研究负责细胞毒性和抗自由基潜能的单个成分。

To investigate the effect of formononetin on phosphatase and tensin homology deleted on chromosome ten/protein kinase B signaling pathway and angiogenesis of transplanted tumor in nude mice with breast cancer cells. Nude mice with breast cancer cell transplanted tumors were established and randomly divided into control group, low (0.1 mg/g) and medium (0.2 mg/g) doses of formononetin, high (0.4 mg/g) and taxol (10 µg/g) groups, after grouping treatment, the transplanted tumor volumes of nude mice in each group were measured; terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining was used to detect the apoptosis of transplanted tumor cells; the angiogenesis (proportion of cluster of differentiation 31 positive cells) of transplanted tumors was detected by immunohistochemical staining; serum vascular endothelial growth factor levels in nude mice were detected by enzyme-linked immunosorbent assay; the expressions of vascular endothelial growth factor and phosphatase and tensin homology deleted on chromosome ten/protein kinase B pathway related proteins in transplanted tumors were detected by Western blot assay. Compared to the control group, the volumes of transplanted tumors, the proportion of cluster of differentiation 31 positive cells, serum vascular endothelial growth factor levels, vascular endothelial growth factor protein expression, and phosphorylated-protein kinase B/protein kinase B of nude mice were decreased, while the proportion of apoptotic cells and phosphatase and tensin homology deleted on chromosome ten protein expression were increased in a dose-dependent manner (p<0.05) in low, medium and high doses of formononetin or taxol groups; however, there were no differences in all indexes between taxol group and high dose group of formononetin (p>0.05). Formononetin up-regulates phosphatase and tensin homology deleted on chromosome ten expression, decreases protein kinase B phosphorylation and inhibits transplanted tumor growth and angiogenesis of transplanted tumor in nude mice with breast cancer cells

Pharmacological Uses of Certain Anthraquinones Traditional and ethno-medicinal use of plants enforces a holistic approach towards human health by wittily utilizing the synergistic potency of the bioactive compounds. Quinones are unique molecules with several therapeutic properties that lead them as most vital compound in pharmaceutical system. They can easily undergo reduction reaction paving the path for many biological processing. This class of molecules helps in treatment of several chronic ailments. Many of the drugs in Ayurvedic formulations and/or modern medicinal sectors are having one or more types of quinone groups as a major bio-active compound. However these aforementioned properties of quinones make them unique and versatile. The biochemical knowledge of these compounds is necessary to understand their physiological and toxicological properties. Amongst all quinones found naturally, anthraquinones are one of its kinds due to wide spectrum utilization in several drug formulations. In this review a brief detail of six unique yet ethno-botanically and pharmacologically versatile quinone compounds are depicted with their natural resources, structural characterization and ethno-pharmacological activities. The gathered information regarding the above mentioned bio-active compounds would be helpful in identification and isolation of these compounds from a wide range of natural sources with structural characterization and pharmacological potency. These data would be pivotal in their precise identification for further use in both Ayurvedic and modern drug formulation sectors thereby lessening the threat status of the frequently used rare, endangered and threatened plants.
某些蒽醌类药物的药理用途植物的传统和民族医学用途通过巧妙地利用生物活性化合物的协同效力,强制采用一种全面的方法来保护人类健康。醌是一种独特的分子,具有多种治疗特性,是药物系统中最重要的化合物。它们很容易发生还原反应,为许多生物处理铺平了道路。这类分子有助于治疗几种慢性疾病。阿育吠陀配方和/或现代医药部门的许多药物都含有一种或多种醌类,作为主要的生物活性化合物。然而,上述醌类的性质使它们独特而多功能。了解这些化合物的生化知识对于了解它们的生理和毒理学特性是必要的。在所有天然发现的醌类中,蒽醌类是其中一种,因为它在几种药物配方中具有广泛的光谱利用。本文简要介绍了六种独特的民族植物学和药理学上通用的醌类化合物的天然资源、结构特征和民族药理学活性。所收集的有关上述生物活性化合物的信息将有助于从广泛的天然来源中鉴定和分离这些具有结构表征和药理学效力的化合物。这些数据对于在阿育吠陀和现代药物配方部门进一步使用它们的精确识别至关重要,从而减少经常使用的稀有、濒危和受威胁植物的威胁状况。
