Molecular mechanism of microRNA-29a-3p targeting Serpinhl regulating proliferation and invasion of human gastric cancer cell line BGC823 / 解剖学报

Objective To investigate the effects of microRNA( miR)-29a-3p on the proliferation and invasion of gastric cancer cells and analyze its related molecular mechanism. Methods The expression level of miR-29a-3p in gastric cancer cells was detected, and the role of miR-29a-3p in the proliferation, migration, and invasion of gastric cancer cells was evaluated. Western blotting and luciferase analysis showed that miR-29a-3p was directly bound to Serpinhl 3 ' -untranslated region(3' UTR). In addition, the effects of the miR-29a-3p/Serpinhl axis on the proliferation, migration, and invasion of gastric cancer cells were detected by MTT assay, colony formation assay, and Transwell assay in vitro. Results After transfection, the expression of miR-29a-3p in the miR-29a-3p mimic group was significantly higher than that in the miR-29a-3p negative control and blank group. After transfection, the proliferation of BGC823 cells decreased significantly. Luciferase analysis showed that miR-29a-3p inhibited the expression of Serpinhl by targeting the 3 ' UTR of Serpinhl. In addition, overexpression of miR-29a-3p significantly inhibited the proliferation, invasion, and migration of gastric cancer cells by targeting Serpinhl. Conclusion MiR-29a-3p can target Serpinhl and regulate the proliferation and invasion of gastric cancer cells.

Objective:To investigate the effect of rhein on aquaporin 4 （AQP4） and brain edema after cerebral ischemia and the role of microglia-mediated inflammation in this process. Method:The modified thread embolization method was selected to establish the cerebral ischemia model of the right middle cerebral artery embolism （MCAO） in rats. The rats were divided into sham operation group， model group， minocycline group， and high， medium and low-dose rhein groups （3.46，1.73，0.865 mg·kg^-1）. The neurobehavioral function was measured by a modified neurobehavioral score. Wet and dry weight methods were used to measure the changes of water content in brain tissue of rats with cerebral ischemic injury. Western blot was used to detect the expressions of interferon-<italic>γ</italic> （IFN-<italic>γ</italic>） and interleukin-2 （IL-2） in the peripheral ischemic area of rats in each group. Immunofluorescence double labeling method was used to detect the expressions and localization of microglia fine markers Iba-1 and AQP4. Result:Compared with the sham operation group， neurological function score and water content on the side of brain tissue injury of the model group were significantly increased （<italic>P</italic><0.05）. Compared with the model group， the neurological function score and the water content of the brain tissue of each drug group were reduced （<italic>P</italic><0.05， <italic>P</italic><0.01）. Compared with sham operation group， the protein expressions of IFN-<italic>γ</italic> and IL-2 in the model group increased significantly （<italic>P</italic><0.05）. Compared with the model group， the protein expressions of IFN-<italic>γ</italic> and IL-2 in the peripheral area of cerebral ischemia of each drug group were significantly improved （<italic>P</italic><0.05， <italic>P</italic><0.01）. Immunofluorescence double staining results showed that compared with the sham operation group， the model group showed significant increase in the fluorescence expression of AQP4 protein on activated microglia， while each drug group could reduce the fluorescence expression of AQP4 protein on activated microglia， different levels of activated microglia markers Iba-1 and AQP4 were co-localized in the peripheral area of cerebral ischemia in each group. Conclusion:Rhein could reduce the degree of brain edema caused by cerebral ischemic injury， and its mechanism may be related to the inhibition of microglia-mediated neuroinflammation and the down-regulation of AQP4 expression.

Preparation of hydrophilic Indigo Naturalis based on polyethylene glycol( PEG) surface film-forming method and evaluation / 中国中药杂志

Polyethylene glycol (PEG) surface film-forming method was used to prepare hydrophilic Indigo Naturalis decoction pieces with stable effect.The preparation process of modified Indigo Naturalis was optimized and its microscopic properties,hydrophilicity,antipyretic efficacy,and safety were systematically evaluated.With equilibrium contact angle as assessment index,the influence of modifier type,modifier dosage,dispersant dosage,and co-grinding time on water solubility of Indigo Naturalis was investigated by single factor test.The results showed that the optimal preparation process was as follows.The 6%PEG6000 is dissolved in 10%anhydrous ethanol solution by sonification and then the mixture is ground with Indigo Naturalis for 2 min.The resultant product is dried on a square tray in an oven at 60℃to remove ethanol and thereby the PEG-modified hydrophilic Indigo Naturalis decoction pieces are yielded.The morphological observation under scanning electron microscope (SEM) indicated that the modified Indigo Naturalis had smoother surface than Indigo Naturalis,and energy spectrometer measurement showed that the nitrogen (N),calcium(Ca),oxygen (O),and silicon (Si) on the surface of modified Indigo Naturalis powder were less than those of Indigo Naturalis powder.Modified Indigo Naturalis had the equilibrium contact angle 18.96°smaller,polar component 22.222 m J·m~(-2)more,and nonpolar component 7.277 m J·m~(-2)smaller than the Indigo Naturalis powder.Multiple light scattering technique was employed to evaluate the dispersion in water and the result demonstrated that the transmittance of Indigo Naturalis and modified Indigo Naturalis was about85%and 75%,respectively,suggesting the higher dispersity of modified Indigo Naturalis.The suspension rate of modified Indigo Naturalis in water was determined by reflux treatment.The result showed that 57%of Indigo Naturalis was not wetted after refluxing for1 h,while the modified Indigo Naturalis was all wetted and dispersed into water.The dissolution of indigo and indirubin of modified Indigo Naturalis increased and the process was more stable.Then,rats were randomized into the blank group,model group,acetaminophen group,Indigo Naturalis group,and hydrophilic Indigo Naturalis group.The temperature changes of rats were observed after administration and the concentration of IL-1βand TNF-αin serum and IL-1βand PGE_2in hypothalamus was measured.The results indicated that the temperature of Indigo Naturalis group and hydrophilic Indigo Naturalis group dropped and the IL-1βlevel of the hydrophilic Indigo Naturalis group decreased (P<0.05) as compared with those in the model group.Thus,both Indigo Naturalis and hydrophilic Indigo Naturalis had antipyretic effect,particularly the hydrophilic Indigo Naturalis.The acute toxicity test of hydrophilic Indigo Naturalis verified that it had no toxicity to rats.In this study,the hydrophilic Indigo Naturalis decoction pieces were prepared with the PEG surface film-forming method,and the antipyretic efficacy and safety were evaluated,which expanded the technological means of powder modification for Chinese medicine and provided a method for clinical use of Chinese medicine.

Antipyretic activity and potential mechanism of Indigo Naturalis on 2,4-dinitrophenol-induced fever rat model / 中国中药杂志

As an effective antipyretic medicine,Indigo Naturalis has a long history of application in the field of Chinese medicine.The content of organics,mainly indigo and indirubin,is about 10%. However,the active ingredients and mechanism of its antipyretic effect have not yet been fully elucidated. In view of this,they were investigated in this study with the rectal temperature change as an indicator and 2,4-dinitrophenol-induced fever rats as subjects. The content of PGE2 and c AMP in the hypothalamus and the serum levels of TNF-α,IL-1β and IL-6 were determined by ELISA. Moreover,the plasma samples of fever rats were analyzed by metabonomics in combination with UPLC-Q-TOF-MS for the exploration of potential biomarkers and the discussion on the antipyretic mechanism of Indigo Naturalis and its active ingredients. The results showed that the rising trend of rectal temperature in rats was suppressed 0. 5 h after the treatment with Indigo Naturalis,organic matter,indigo or indirubin as compared with the rats of model group( P < 0. 05),among which Indigo Naturalis and organic matter had better antipyretic effect. ELISA results showed that organic matter and indigo can inhibit the expression of PGE2 and c AMP( P<0. 01),while Indigo Naturalis and organic matter were effective in curbing the increase in TNF-α( P<0. 05). A total of 21 endogenous metabolites were identified from the plasma samples of the Indigo Naturalis,organic matter,indigo and indirubin groups,which were mainly involved in glycerophospholipid metabolism.

Key to Indigo Naturalis' oral effectiveness: in vivo and in vitro verification of bile action / 中国中药杂志

Indigo Naturalis( IN) is mainly composed of 10% organic matter and 90% inorganic matter,with a poor wettability and strong hydrophobicity. Indigo,indirubin and effective ingredients are almost insoluble in water. And how it exerts its effect after oral administration still needs to be revealed. For this reason,this study put forward the hypothesis that " Indigo Naturalis forms a slightly soluble calcium carbonate carrier in a strong acid environment of gastric fluid,and organic substances are solubilized in the bile environment of intestinal fluid",and then verified the hypothesis. First,the dissolution apparatus was used to simulate the change process of IN in different digestive fluid,and the effects of low-dose and normal bile on the dissolution of inorganic substances and the release of organic substances were compared. After the surface morphology and element changes of IN in different digestive fluid were observed,it was found that bile is the key to promoting the dissolution of organic and inorganic substances in IN. Furthermore,the rat fever model induced by 2,4-dinitrophenol was used to study the antipyretic effect of IN in normal rats and bile duct ligation rats. It was found that the antipyretic effect of IN on normal rats was better than that of bile duct ligation rats. The above results indicated that after oral administration of IN,the calcium carbonate carrier was transformed into a slightly soluble state in acidic gastric fluid,and a small amount of organic matter was released. When IN entered the intestinal fluid mixed with bile,the carrier dissolved in a large amount,and indigo and indirubin were dissolved in a large amount,so as to absorb the blood and exert the effect. This study has a certain significance for guiding clinical application of IN. For patients with insufficient bile secretion( such as bile duct resection),oral administration with IN may not be effective and shall be paid attention.

Effects of Jiaotai Pills on CUMS-induced depression model in mice based on changes of SIRT1 expression in hippocampus / 中国中药杂志

The present study investigated the effects and mechanisms of Jiaotai Pills on depressed mice induced by chronic unpredictable mild stress(CUMS). The CUMS-induced depression model mice were established and the depression behaviors of mice were evaluated by sucrose preference test, open field test, tail suspension test, and forced swimming test. Molecular docking was employed to simulate the interaction of six main active ingredients in Jiaotai Pills with SIRT1. Immunohistochemical staining was used to detect the level of SIRT1 in the hippocampus of mice. Western blot was used to detect the protein expression levels of SIRT1, p-NF-κB p65, NF-κB p65, and FoxO1 in the hippocampus of mice. Enzyme-linked immunosorbent assay(ELISA) kits were used to detect the levels of interleukin(IL)-1β, IL-6, tumor necrosis factor-α(TNF-α), and brain-derived neurotrophic factor(BDNF) in the hippocampus and serum of mice. Biochemical kits were used to detect superoxide dismutase(SOD) activity and malondialdehyde(MDA) and glutathione(GSH) levels in the hippocampus and serum of mice. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to detect the levels of dopamine(DA), 5-hydroxytryptamine(5-HT), and norepinephrine(NE) in the hippocampus and serum of mice. The results showed that the sucrose preference rate, movement distance, and the number of crossing centers were reduced in the model group(P<0.01), and the tail suspension time and swimming immobility time were increased(P<0.01). Molecular docking results indicated good binding of six main active ingredients in Jiaotai Pills to SIRT1. In the hippocampus, the expression level of SIRT1 was reduced(P<0.01), and the levels of p-NF-κB p65/NF-κB p65 and FoxO1 were increased(P<0.01). In the hippocampus and serum, the levels of IL-1β, IL-6, TNF-α, and MDA were increased(P<0.01), and the activity of SOD and the levels of GSH, DA, 5-HT, NE, and BDNF were reduced(P<0.01). The treatment with high-dose Jiaotai Pills increased the sucrose preference rate, movement distance, and the number of crossing centers(P<0.05), reduced tail suspension time and swimming immobility time(P<0.01), elevated hippocampal SIRT1 expression level(P<0.01), decreased hippocampal and serum IL-1β, IL-6, TNF-α, and MDA levels(P<0.01), potentiated SOD activity, and up-regulated GSH, DA, 5-HT, NE, and BDNF levels in the hippocampus and serum(P<0.05, P<0.01) in model mice. In conclusion, the results showed that Jiaotai Pills could improve the depression behaviors of model mice with CUMS-induced depression, and the underlying mechanism was related to the up-regulation of SIRT1 in the hippocampus of mice to exert anti-inflammatory and anti-oxidative stress effects.

The key to fine manufacturing of liquid polyphenol preparations: the principle of multi-precipitation with steady-state reconstruction / 药学学报

Plant polyphenols have a wide range of pharmacological activities and application prospects. Liquid polyphenol preparations have special physical phases and complex chemical compositions, with problems such as poor stability and easy precipitation during production and marketing. Taking the multi-precipitation mechanism of plant polyphenol liquid preparations as an example,we discuss the chemistry and composition of the precipitation, how it forms, whether precipitationcan be controlled, and the interaction law of three precipitation approaches. An unstable mechanism model is proposed where hydrolyzed tannin hydrolysis and catechin non-enzymatic oxidative polymerization repeatedly induces associative colloid aggregation and precipitation. This study explains the complex physicochemical changes in polyphenol solutions and the microcosmic mechanism of instability in the induced system and proposes a steady state reconstruction of liquid polyphenol preparation consistent with the common law of precipitation and control. It has scientific significance for promoting the development and manufacture of high quality liquid polyphenol preparations.

Quantitative monitoring of multi-donor chimerism after multi-donor allogeneic hematopoietic stem cell transplantation / 中国实验血液学杂志

This study was aimed to establish a model for detecting the donor chimerism rate following the multi-donor hematopoietic stem cell transplantations, and simplify its calculation method. Patients with hematologic disease receiving allogeneic hematopoietic stem cell transplantation including single-donor and multi-donor were selected in this study and the donor cell chimerism rates were detected, using STR-PCR combined with capillary electrophoresis. The results indicated that the peaks of the sister alleles coming from the same individual were confirmed to have the approximate areas and can be replaced each other in the situation of mixed chimerism. In the calculation model, the value between reference chimerism and approximate chimerism have no significant difference using the hypothetical peak areas, and the result was confirmed to be accepted basing on typical measurement error between sister alleles (5% - 20%). It is concluded that the areas of share peaks can be replaced by non-share peaks and this conclusion can be used to calculate the double-donor CHM (DD-CHM)(%). Compared to the D alleles, R alleles show more strategic importance because it can lead to more accurate result and allowed simplifying the arithmetic calculations for DD-CHM(%).
