ObjectiveTo investigate the anti-convulsant activity of goat horn and its effect on the main neurotransmitters in the brain of model mice. MethodA total of 120 mice were randomly divided into a blank group，a model group，a positive drug group （estazolam， 1 mg·kg^-1）， a Saigae Tataricae Cornu （STC， 0.2 g·kg^-1） group， and low- （1.25 g·kg^-1） and high-dose （2.5 g·kg^-1） goat horn groups. Drugs were administered by gavage once at 10 mL·kg^-1. Those in the blank group and the model group were given the same volume of 0.2% sodium carboxymethyl cellulose （CMC-Na）. The mice underwent threshold electrical stimulation once 2 h after administration. Ankylosing convulsion in the hind limbs of mice was used as the index to calculate the recovery period， convulsion rate， and mortality of ankylosing convulsion. Ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） was established to analyze the changes in the content of the main neurotransmitters in the brain tissues of mice. ResultTwo hours after intragastric administration of goat horn powder to mice， the recovery period of convulsion could be shortened and the convulsion rate and mortality were reduced （P<0.05）. In terms of anti-convulsant effect， the groups were ranked as follows： high-dose goat horn group > STC group > low-dose goat horn group. UPLC-MS/MS analysis showed that compared with the results in the model group， goat horn powder and STC decreased the content of glutamic acid and aspartic acid （P<0.05） and increased the content of glycine， γ-aminobutyric acid， and 5-hydroxytryptamine （P<0.05）. ConclusionThe results showed that goat horn had a significant anti-convulsant effect on the electroshock-induced convulsion mouse model， and the underlying mechanism was presumably attributed to the improvement of the development of convulsion by regulating the changes in neurotransmitter content in brain tissues.

OBJECTIVES: To explore the cytotoxicity of four wild mushrooms involved in a case of Yunnan sudden unexplained death (YNSUD), to provide the experimental basis for prevention and treatment of YNSUD. METHODS: Four kinds of wild mushrooms that were eaten by family members in this YNSUD incident were collected and identified by expert identification and gene sequencing. Raw extracts from four wild mushrooms were extracted by ultrasonic extraction to intervene HEK293 cells, and the mushrooms with obvious cytotoxicity were screened by Cell Counting Kit-8 (CCK-8). The selected wild mushrooms were prepared into three kinds of extracts, which were raw, boiled, and boiled followed by enzymolysis. HEK293 cells were intervened with these three extracts at different concentrations. The cytotoxicity was detected by CCK-8 combined with lactate dehydrogenase (LDH) Assay Kit, and the morphological changes of HEK293 cells were observed under an inverted phase contrast microscope. RESULTS: Species identification indicated that the four wild mushrooms were Butyriboletus roseoflavus, Boletus edulis, Russula virescens and Amanita manginiana. Cytotoxicity was found only in Amanita manginiana. The raw extracts showed cytotoxicity at the mass concentration of 0.1 mg/mL, while the boiled extracts and the boiled followed by enzymolysis extracts showed obvious cytotoxicity at the mass concentration of 0.4 mg/mL and 0.7 mg/mL, respectively. In addition to the obvious decrease in the number of HEK293 cells, the number of synapses increased and the refraction of HEK293 cells was poor after the intervention of Amanita manginiana extracts. CONCLUSIONS The extracts of Amanita manginiana involved in this YNSUD case has obvious cytotoxicity, and some of its toxicity can be reduced by boiled and enzymolysis, but cannot be completely detoxicated. Therefore, the consumption of Amanita manginiana is potentially dangerous, and it may be one of the causes of the YNSUD.

This paper explored the specific peptides from Bubali Cornu by ultra-performance liquid chromatography-tandem mass spectrometry and based on mathematics set theory. Following the profile analysis of peptides from Bubali Cornu, Bovis Grunniens Cornu, Caprae Hircus Cornu, and Suis Cornu by nano LC-LTQ-Obitrap-MS after digestion with trypsin, the relationship of peptide composition among different samples was analyzed using the mathematics set theory. The ones that existed only in the Bubali Cornu set rather than in any other set were considered as the specific peptides of Bubali Cornu. The further bioinformatic analysis revealed four specific peptides from Bubali Cornu, whose specificity was verified by UPLC-QQQ-MS. The results showed that these four peptides could be used for distinguishing Bubali Cornu from Caprae Hircus Cornu and Suis Cornu. This study has provided a rapid and simple method for seeking the specific peptides in animal medicines, which can be utilized for quality evaluation of animal medicines, thus making them authenticable and traceable.

The effects of Chloriti Lapis on metal elements in plasma and lung tissue of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) rats were studied. The rat AECOPD model with phlegm heat syndrome was established by smoking combined with Klebsiella pneumoniae infection. After the rats were treated by Chloriti Lapis,the contents of metal elements in plasma and lung tissue were determined by inductively coupled plasma-optical emission spectroscopy( ICP-OES) and inductively coupled plasma mass spectrometry( ICP-MS). The changes in the contents of metal elements were analyzed by SPSS 18. 0. Further,the correlations of differential metal elements( including Cu/Zn ratio) with differential metabolites in plasma,lung tissue and urine of AECOPD rats treated with Chloriti Lapis were analyzed. The results showed that Chloriti Lapis significantly up-regulated the contents of Fe,Al,Mn,Cu,Zn,Sn( P<0. 05),V,Co( P< 0. 01) and Cu/Zn ratio( P< 0. 05),and significantly down-regulated the contents of Ti( P< 0. 05)and Pb( P<0. 05) in the model rat plasma. It significantly increased the content of Be( P<0. 05) and decreased the contents of Mg,Ti and Al( P<0. 01) in model rat lung tissue. The element profiles of normal group,model group and Chloriti Lapis group can be well separated. Chloriti Lapis group and other groups were clustered into two categories. The taurine in plasma and phytosphingosine in lung tissue had the strongest correlations with differential metal elements. The Fe,Al,Mg,Be,Ti,V,Mn,Cu,Zn,Sn,and Co in Chloriti Lapis may directly or indirectly participate in the intervention of AECOPD rats. This group of metal elements may be the material basis of Chloriti Lapis acting on AECOPD rats,and reduce the Cu/Zn value in vivo. It was further confirmed that Chloriti Lapis could interfere with the metabolic pathways of taurine and hypotaurine in plasma and urine as well as the sphingolipid metabolism pathway in lung tissue of AECOPD rats. In addition,this study confirmed that long-term smoking can cause high-concentration Cd accumulation in the lung and damage the lung tissue.

To study the effect of mineral Chloriti Lapis on pulmonary metabolites and metabolic pathways in lung tissues of rats with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). The AECOPD rat model of phlegm heat syndrome was replicated by the method of smoking combined with Klebsiella pneumoniae infection. Except for using UPLC-Q-TOF-MS analysis, SPSS 18.0, SIMCA 13.0 and other software were also used for statistical analysis. Through literature search and online database comparison, the differential metabolites were identified, and the possible metabolic pathways were analyzed. After 15 days of administration, PLS-DA analysis was carried out on lung tissue samples of rats in each group. The results showed that the metabolic profiles of lung tissues of rats in each group could be well separated, which indicated that Chloriti Lapis and aminophylline had significant intervention effect on the lung metabolic profile of rats with AECOPD. Moreover, the metabolic profile of Chloriti Lapis group was closer to that of control group, and the intervention effect was better than that of aminophylline group. As a result, 15 potential differential metabolites were identified: phytosphingosine, sphinganine, tetradecanoylcarnitine, L-palmitoylcarnitine, elaidic carnitine, lysoPC[18∶2(9Z,12Z)], lysoPC(16∶0), lysoPC[18∶1(9Z)], lysoPC(18∶0), stearic acid, lysoPC(15∶0), arachidonic acid, docosapentaenoic acid, linoleic acid and palmitic acid. Among them, Chloriti Lapis could significantly improve the levels of 10 differential metabolites of phytosphingosine, tetradecanoylcarnitine, L-palmitoylcarnitine, elaidic carnitine, lysoPC[18∶2(9Z,12Z)], lysoPC(16∶0), lysoPC[18∶1(9Z)], stearic acid, lysoPC(15∶0), and palmitic acid(P<0.05). The intervention effect of Chloriti Lapis group was better than that of aminophylline group. Analysis of metabolic pathways showed that there were 8 possible metabolic pathways that could be affected, and three of the most important metabolic pathways(pathway impact>0.1) were involved: linoleic acid metabolism, arachidonic acid metabolism, and sphingolipid metabolism. Chloriti Lapis had obvious intervention effects on lung tissue-related metabolites and metabolic pathways in rats with AECOPD, and the effect was better than that of aminophyllinne.

To study the differences and similarities in pharmaceutical characterization and pharmacodynamic characterization between the single decoction and merger decoction of Baihu and Guizhi. The same technology parameters were used to prepare Baihu and Guizhi single decoticon and merger decoction extracts, and then the differences and similarities in pharmaceutical characterization were analyzed based on their HPLC fingerprint, content of index components, and the extraction content. The pharmacodynamic differences and similarities were analyzed by inflammatory model and pain model. There was no significant difference in HPLC chromatographic peak, but the peak area value reflected the difference of quantity to some extent. It was found that the peak value of single Rhizoma anemarrhenae and Cassia twig decoction was less than the peak of their merger decoction, but the peak value of single honey-fried Licorice root decoction was greater than the peak of merger decoction． The contents of neomangiferin, mangiferin and timosaponin B Ⅱ among index components as well as extraction content in merger decoction were higher than those in single decoction． The contents of liquiritin and glycyrrhizic acid as well as extraction content in merger decoction were lower than those in single decoction． There was no significant difference in the content of cinnamicacid and its extraction content between merger decoction and single decoction. According to the efficacy experiment, both of them showed significant anti-inflammatory and analgesic effects. However, the merger decoction showed faster anti-inflammation effect, and longer analgesic effect. It can be concluded that the merger decoction and single decoction of Baihu and Guizhi have the same material basis, and the merger decoction is better for the dissolution of the active ingredients in this recipe, and is more beneficial to the therapeutic effect.
