Diabetic kidney disease (DKD) has become a primary cause of end-stage kidney disease, without any effective treatment available. In this study, we assessed the protective effect of Guanxin Danshen Formula (GXDSF) on diabetic nephropathy in db/db mice. The db/m and db/db mice were randomly divided into four groups: a control group, a model group, a metformin group, and a GXDSF group. After 8 weeks’ treatment with GXDSF, metformin or normal saline, the mice were sacrificed, and the blood and kidney tissues were collected for further analysis. Compared with the model group, the TG, TCH and LDL levels significantly decreased in the GXDSF group. The results from HE and PAS staining showed that db/db mice exhibited abnormal kidney tissues with increased glomerular volume, basement membrane thickening and mesangial cell proliferation, which could be significantly alleviated by GXDSF treatment. GXDSF treatment also reduced serum creatinine and BUN. Meanwhile, GXDSF treatment markedly elevated the GSH-PX levels, while reduced the LDH and MDA levels in the kidney tissues. Western blot assay showed that GXDSF evidently up-regulated the protein levels of ER
α and p-Akt, and subsequently promoted the HO-1 expression mediated by Nrf2. These data collectively indicated that GXDSF protected db/db mice against DN by regulating the ER
α and Nrf2-mediated HO-1 expression.
A new isoquinoline alkaloid (1) was isolated from the whole plant of
Thalictrum glandulosissimum by using various chromatographic techniques, including silica gel, sephadex, MCI-gel resin, and RP-HPLC, and its structure was determined as 1-(6-hydroxy-7-methylisoquinolin-1-yl)ethantone by physicochemical properties and spectroscopic data. This compound was evaluated for anti-tobacco mosaic virus (TMV) activity. The results showed that it had a prominent anti-TMV activity with inhibition rates of 28.4%. This rate was closed to that of positive control.
Corydalis Bungeanae Herba is often used to treat a variety of inflammatory diseases in traditional Chinese medicine. In order to determine its chemical material basis, the components of Corydalis Bungeanae Herba were isolated by an automated purification system. Flavonoids and alkaloids were prepared, and all such components were identified by mass spectrometry. The effects of the components on the production of inflammatory mediators and pharmacological mechanisms in the lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model were examined. Mouse macrophages (RAW264.7) were first treated with LPS. The relationship between cell viability and LPS concentration was observed. Then, the effects of flavonoid and alkaloid components with different administration concentrations on cell viability were detected to determine the maximum administration concentration. Secondly, 2.5, 5, 10 and 20 μg·mL
−1 flavonoid and alkaloid components were added respectively to observe the effects and mechanism of different concentrations of flavonoid and alkaloid components on LPS-induced inflammation of RAW264.7 macrophages. Griess reagent assay was used to detect NO content in cell supernatant. The inflammatory cytokines (TNF-
α, IL-1
β and IL-6) in cell supernatant were determined by ELISA method. Western blot method was used to detect the intracellular nuclear factor (NF-κB) IκB
α phosphorylation (p-IκB
α), p65 phosphorylation (p-p65) and protein expression of TLR4 and TLR2. The results showed that the alkaloid components inhibited the production of NO, TNF-
α, IL-1
β and IL-6 in a dose-dependent manner in the concentration range of 2.5–20 μg·mL
−1. In inflammation upstream pathways, the inhibitory effect of the alkaloid components on the TLR2 expression level was weaker than that of TLR4. In inflammation downstream, alkaloid components significantly inhibited the phosphorylation of IκB
α and p65 in a dose-dependent manner. These data suggested that the alkaloid components were the material basis of Corydalis Bungeanae Herba, and its anti-inflammatory mechanism might be related to inhibiting the transmission of inflammatory signals in TLRs/NF-κB signaling pathways dominated by TLR4, interfering with the activation of inflammatory genes and inhibiting their over expression, and down-regulating the secretion level of inflammatory factors.
Ethylene responsive factor (ERF), one of the largest families of transcription factors in plants, plays a key role in secondary metabolism of herbal plants. To analyze the expression of ERF family genes, this study used the heat map clustering method to analyze the ginseng transcriptomes of different parts and different growth years. The content of ginsenosides Rg
1, Re and Rb
1 in various concentrations of MeJA-treated ginseng adventitious roots was determined by the UPLC-MS/MS method. The expression of key genes of ginsenoside biosynthesis (
DDS,
CYP716
A47,
CYP716
A53
v2) and
ERF family genes in MeJA-treated
P. ginseng adventitious roots was determined by using real-time quantitative PCR. Pearson correlation was adopted to analyze the gene expression patterns of
DDS,
CYP716
A47,
CYP716
A53
v2 gene and
ERF family. The results showed that the content of protopanaxadiol ginsenoside Rb
1 in
P. ginseng adventitious roots treated with different concentrations of MeJA increased, and the content of protopanaxatriol ginsenoside Rg
1 and Re decreased. It is consistent with the increase in
DDS and
CYP716
A47 expression and the decrease in
CYP716
A53
v2 gene expression. The expression of
ERF003,
ERF118 and
ERF012 genes was significantly positively correlated with
CYP716
A53
v2, but negatively correlated with
DDS. While the expression of
ERF1
B was significantly negatively correlated with
CYP716
A47. It is proved that
ERF003,
ERF118 and
ERF012 were likely to inhibit the expression of
DDS and promote the expression of
CYP716
A53
v2, and
ERF1
B was likely to inhibit
CYP716
A47. This work could provide a theoretical basis of ERF functional verification of regulating the biosynthesis of ginsenosides.
In this study, the contents of Cu, As, Cd, Pb and Hg in 10 batches of Gardeniae Fructus and 10 batches of fried Gardeniae Fructus from Fuzhou in Jiangxi were determined by inductively coupled plasma mass spectrometry(ICP-MS), and the target hazard coefficient(THQ) for different drug users(adults and children) was calculated by using the international health risk assessment model. According to the ISO and green industry standard, the content of Hg in 4 batches of Gardeniae Fructus exceeded the standard with an over-standard rate of 40%. The THQ and total THQ of Hg in 2 batches of Gardeniae Fructus were higher than the international standard limit of Gardeniae Fructus. For 10 batches of fried Gardeniae Fructus, the content of every heavy metal and total amount of five heavy metals did not exceed the standard. However, the THQ and total THQ of Hg in 1 batch of fried Gardeniae Fructus were higher than the international standard limit of Gardeniae Fructus. As compared with Gardeniae Fructus, the contents of Cu, Pb and Hg in fried Gardeniae Fructus decreased by 34.0%, 77.6% and 23.1%; the THQ of Cu, Pb and Hg for adults decreased by 33.3%, 75.0% and 96.9%; and the THQ of Cu, Pb and Hg for children decreased by 37.5%, 75.0%, 90.7%. It showed that the contents of heavy metals in individual batches of Gardeniae Fructus in this experiment had a certain risk to human health, but the contents of these heavy metals in fried Gardeniae Fructus had no obvious effect on human health. This study provided experimental basis and research ideas for safety evaluation of Gardeniae Fructus and fried Gardeniae Fructus.
This study aims to reveal the pharmacokinetics of Shuganning Injection in normal rats. In this experiment, ultra-high performance liquid chromatography-electrospray-tandem mass spectrometry (UPLC-ESI-MS/MS) was used to establish an analytical method for simultaneous determination of chlorogenic acid, gardenioside, oroxylin A and baicalin in rat plasma. Then, the non-compartmental model (NCA) in Phoenix WinNonLin 6.4 software was used to fit pharmacokinetic parameters. The methodological validation showed that the linear relationship of the components in rat plasma samples was good (
r > 0.995). The recovery rate and matrix effect of plasma samples with low, middle and high concentration were 79.14%–101.4%. The intra-day and inter-day precision, accuracy and stability met the requirements of biological sample analysis. The half-life (
t1/2) of chlorogenic acid, gardenioside, oroxylin A did not change significantly and the area under blood concentration-time curve (AUC
0–
t) was proportional to the dose, which suggested that three components showed a linear kinetic characteristics, but baicalin showed nonlinear kinetic characteristics. Moreover, the retention time of each component in rats was short. The established UPLC-MS/MS quantitative analysis method was rapid, sensitive and accurate, which can be used for the determination of chlorogenic acid, gardenioside, oroxylin A and baicalin in rat plasma and pharmacokinetic study of Shuganning Injection.
