Clinical study on aconite prescriptions with incompatible herbs in different areas based on association rules and analysis on compatibility features / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the current application and features of Aconite prescriptions with incompatible herbs in grade A class three hospitals in east China and central China through a clinical study and comparative analysis.</p><p><b>METHOD</b>Clinical prescriptions containing Aconite with incompatible herbs were collected. Association rules were utilized to analyze the compatible features of these herbs.</p><p><b>RESULT</b>This analysis found that the frequently used incompatible herba; pairs are Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, with the support rate of 44.45%, occupying nearly half of the surveyed prescriptions; Pinelliae Rhizoma is the most frequently used herb in the two areas, with support rate up to 76.24%. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata and Pinelliae Rhizoma, the top 10 herbs in Central China were mostly for warming the middle jiao and tonifying qi, such as Zingiberis Rhizoma, Atractylodis Macrocephalae Rhizoma and Codonopsis Radix; Whereas those in east China were mostly for activating and nourishing blood, such as Angelicae Sinensis Radix, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, the core herbal pairs applied in central China were mainly for resolving phlegm and warming the middle jiao, such as Pinelliae Rhizoma-Glycyrrhizae Radix et Rhizoma, Pinelliae Rhizoma-Zingiberis Rhizoma; Whereas those in east China were principally for activating blood and tonifying qi, like Atractylodis Macrocephalae Rhizoma and Pinelliae Rhizoma, Angelicae Sinensis Radix and Pinelliae Rhizoma. Among the core herbal groups in the two areas, the most frequently used herbal groups in the two areas are Aconiti Lateralis Radix Praeparata, Glycyrrhizae Radix et Rhizoma and Pinelliae Rhizoma with the support rate of 59.73%, accounting for the highest proportion among all of herbal groups.</p><p><b>CONCLUSION</b>There are the combined clinical application of Aconite with incompatible herbs, mostly with Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, but with differences in the combined application in east China and central China.</p>

Effect of Xianxiong decoction on acute lung injury mice induced by lipopolysaccharide / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.</p><p><b>METHOD</b>Eighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.</p><p><b>RESULT</b>Compared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.</p><p><b>CONCLUSION</b>Xianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).</p>

The effect of Qi'ao Decoction on ovalbumin induced and lipopolysaccharide enhanced severe asthma mice and its mechanism / 中国天然药物

AIM@#To evaluate the effect of Qi'ao Deocoction (QAD) on the inflammation and hyperresponsiveness of asthma mice.@*METHODS@#120 Balb/C mice were randomly divided into six groups: normal group, model group, dexamethasone group, high dose QAD group, medium dose QAD group and low dose QAD group. The asthma model was reproduced in Balb/C mice sensitized by ovalbumin, challenged by OVA and LPS. The mice of the normal group were sensitized, challenged and intranasally instilled by PBS. On day 28-34, 6.7, 13.4 and 26.8 g · kg(-1) Qi'ao Decoction were administrated; 0.002 4 g · kg(-1) dexamethasone solution was given to the dexamethasone group; normal and model groups were given the same amount of normal saline. Bronchoalveolar lavage fluid, airway hyperresponsiveness, lung histopathology and cytokines were then collected and analyzed.@*RESULTS@#Compared with normal group, total cellular score, the number of macrophages, lymphocytes, eosinophils and neutrophils of model group significantly increased (P 0.05).@*CONCLUSION@#QAD can significantly inhibit airway inflammation and airway hyperresponsiveness of mice with severe asthma induced by ovalumin and lipopolysaccharide, adjust the balance of cytokines, and improve lung histopathological condition. So, it exhibits great effect on severe asthma.

Effect of San'ao Decoction on the airway inflammation and hyperresponsiveness in a murine model of lipopolysaccharide-enhanced asthma / 中国结合医学杂志

<p><b>OBJECTIVE</b>San'ao Decoction (, SAD), as a representative Chinese medicine (CM) formula, was chosen to evaluate the effect of airway inflammation and hyperresponsiveness on the lipopolysaccharide (LPS) enhanced asthma model.</p><p><b>METHODS</b>The asthma model was reproduced in the Balb/C mice sensitized by ovalbumin (OVA), challenged by OVA and LPS. After Balb/C mice's administration of a dose (0.0024 g/kg) of dexamethasone acetate, and three doses (2.2 g/kg, 4.4 g/kg and 8.8 g/kg) of SAD, airway inflammation and responsiveness were observed. The airway inflammation was detected by counting bronchoalveolar lavage fluid (BALF) cells and lung histopathology. Also, differential expressions of interferon-r (IFN-γ), interleukin-4 (IL-4), and IL-5 in the supernatants of BALF were examined. The changes in airway responsiveness indicated by lung resistance (R(L)) and stimulated by acetylcholine (Ach) were determined.</p><p><b>RESULTS</b>Small-dose SAD hardly inhibit airway inflammation or hyperresponsiveness in the LPS-enhanced asthma, while medium-dose and high-dose SAD significantly inhibited the airway hyperresponsiveness, and to some extent, reduced airway inflammation. Meanwhile, the small-dose, medium-dose, and high-dose SAD promoted Th1-type cytokines (IFN-γ) and reduced Th2-type cytokines (IL-4, IL-5) to different extents, which led to a Th1/Th2 balance.</p><p><b>CONCLUSION</b>SAD has a good therapeutic effect on airway hyperresponsiveness in the LPS-enhanced asthma model, but its definite influence on airway inflammation is not remarkable.</p>
