IL-8 and MIP-2 mRNA levels in vaginal mucosa of mice were detected by qRT-PCR. The results showed that as compared with the normal group, VVC model group had a large number of hyphae and a high level of fungal loadinvagina. The vaginal mucosa was completely destroyed, the number of neutrophils increased, and the protein and mRNA levels of IL-8 and MIP-2 were up-regulated. After BAEB treatment, the hyphae of the treatment group was decreased, the fungal load was decreased, the impaired mucosa showed different degrees of improvement, the inflammatory factors were decreased to varying degrees, and the protein and mRNA levels of chemokine IL-8 and MIP-2 were down-regulated. In conclusion, BAEB may be used to treat VVC by inhibiting vulvovaginal candidiasis via blocking neutrophils recruitment into vagina.In this paper, some quality problems of mineral medicine Calamina and calcined Calamina have been discussed after determination and analysis of the quality parameters of a large number of market samples, and the countermeasures are put forward. According to the XRD results, as well as the results of tests included in Chinese Pharmacopoeia(2015 edition), the authenticity of Calamina and calcined Calamina samples were identified. The content of zinc oxide in samples were determined by the method of determination in Chinese Pharmacopoeia. Individually, inductively coupled plasma mass spectrometry(ICP-MS), inductively coupled plasma atomic emission spectrometry(ICP-AES) and atomic fluorescence spectrometry(AFS) methods were used for the determination of impurity elements and harmful elements in Calamina and calcined Calamina samples. Four kinds of impurity elements of magnesium(Mg), iron(Fe), aluminum(Al), calcium(Ca) and five harmful elements such as lead(Pb), cadmium(Cd), arsenic(As), copper(Cu), mercury(Hg) welcined Calamina, in order to cope with the current shortage of Calamina resources and ensure the sustainable development of Calamina medicinal materials.Eight compounds were isolated from the ethyl acetate extraction of Prunus mume by column chromatography. On the basis of physicochemical properties and spectrum analysis, these compounds were identified as isoquercitrin-6″-O-benzoate(1), pinoresinol(2), naringin(3), ethyl-β-D-glucopyranoside(4), astragalin(5), quercetin(6), hypericin(7), and rutin(8). Among them, compound 1 was a new natural product, and compounds 2-5 were isolated from this plant for the first time. In vitro study, compounds 1, 3, 5-8 could significantly increase the cell survival ratio.Pinellia ternata belongs to the Araceae family and is a medicinal herb. EGFR assay The tuber is the medicinal organ with antitussive, antiemetic and anti-tumor activities. It is easy to encounter high temperature environment during the growth periods, leading to decrease of tuber production. At present, the mechanism of response to high temperature stress in P. ternata is still unknown. DNA methylation plays a vital role in plant protection against adversity stress as a way of epigenetic regulation. In this study, P. ternata was used as material for treatment of high temperature stress at 0 h, 6 h and 80 h, and methylation sensitive amplification polymorphism(MSAP) analysis was conducted on the changes of DNA methylation in its genome. The results showed that 20 pairs of MSAP primers were selected from 100 MSAP primers with multiple clear and uniform bands, and 353, 355 and 342 loci were amplified from materials of P. ternata treated in the high temperature stress 0 h, 6 h and 80 h, respectively. Cytosine methylation levels of CCGG context in the above materials were characterized as 60.91%, 44.79% and 44.74%, respectively. And the full methylation ratios were 16.71%, 22.25% and 29.24, respectively. It demonstrated that high temperature stress significantly induced the down-regulation of DNA methylation level and up-regulation of the full methylation rate in P. ternata genome. This study provides a preliminary theoretical reference for analyzing the mechanism of P. ternata responding to high temperature stress from the epigenetic perspective.A new method on functional orientation of Moringa leaves based on text mining and molecular docking was explored in the study. First, PubMedplus was used to analyze research data on Moringa leaves collected in PubMed and the indications of Moringa leaves were screened along with the hotspots and development tendency of Moringa leaves. Second, Arrowsmith was used to obtain the biological targets of Moringa leaves. Third, active candidate components of Moringa leaves were filtered by SwissADME analyzing on chemical data collected from literatures. Subsequently, molecular docking between active candidate component and target was studied by systemsDock to forecast the potential active components and their possible effective targets, and GO functional annotation of the potential targets was performed by DAVID database. According to the results, tumor, diabetes and digestive diseases were suggested to be indications of Moringa leaves, correlated with 25 active components and 12 potential effective targets possibly by adjusting G protein-coupled receptor and affecting on inflammatory reaction. The new method on functional orientation by combining text mining with molecular docking was successfully practiced on Moringa leaves as a case study,which provides a useful reference for the ultilization of foreign medicinal resource.Atropa belladonna seedlings were used as experimental materials and cultivated by soil culture method. Different concentrations(0,0.05,0.1,0.2,0.5 mmol·L~(-1))of NO donor sodium nitroprusside(SNP) were sprayed on the leaves. The effects of different concentrations of SNP and different treatment time(4,8,12,16 d) on nitrogen metabolism, secondary metabolite content, precursor content of tropane alkaloid synthesis pathway and expression of key enzyme genes under 100 mmol·L~(-1) NaCl stress were studied. The results showed that with the prolongation of salt stress, the nitrogen metabolism and the accumulation of secondary metabolites of A. belladonna were inhibited to some extent. After treatment with different concentrations of exogenous SNP, the ammonium nitrogen content decreased dramatically, and the contents of nitrate nitrogen, free amino acid, soluble protein and the activities of key enzymes of nitrogen metabolism(NR, GS, GDH) were all greatly improved; the contents of precursor amino acids(ornithine, arginine) and polyamines(Put, Spd, Spm) in the secondary metabolic pathway have increased to varying degrees.
