Objective:To study the effect of sedimentary type Limonitum on hemostatic indexes in blood and metal ions in serum of rats with hemorrhage. Method:The hemorrhagic rat models were established by warfarin sodium. The experimental animals were divided into control group，model group，powder group and water decoction group. On day 15 from drug administration， the contents of 6-keto prostaglandin F₁<italic>_α</italic>（6-keto-PGF₁<italic>_α</italic>），thromboxane B₂（TXB₂），arachidonic acid（AA），endothelin 1（ET-1），platelet activating factor（PAF），P-selectin（PS），and Ca²⁺ in the whole blood of rats in each group were determined by enzyme-linked immunosorbent assay（ELISA）. The contents of Na，Mg，K，Ca，Fe，Al，Li，Be，Ti，V，Cr，Mn，Co，Ni，Cu，Zn，As，Sr，Cd，Sn，Sb，Ba，and Pb in serum samples were determined by inductively coupled plasma optical emission spectrometer（ICP-OES） and inductively coupled plasma mass spectrometry（ICP-MS）. Result:Compared with the model group，the content of 6-keto-PGF₁<italic>_α</italic> was reduced in the powder group and water decoction group （<italic>P</italic><0.05），and the contents of TXB₂，AA，ET-1，PAF，PS，Ca²⁺weresignificantly increased（<italic>P</italic><0.01），with a positive and beneficial regulatory effect. In the powder group， 10 kinds of metal elements in serum of rats were significantly and positively regulated： Na，K，Ca，Fe，Li，Ti，V，Co，Cu，and Zn（<italic>P</italic><0.05，<italic>P</italic><0.01）. In the water decoction group， 10 metal elements with significant positive regulation were as follows： Na，K，Ca，Fe，Li，V，Ni，Cu，Zn，and Sr（<italic>P</italic><0.05，<italic>P</italic><0.01）. In addition，the content of Cr（<italic>P</italic><0.01） in the powder group and Cr（<italic>P</italic><0.01），Pb（<italic>P</italic><0.05） in the water decoction group were significantly reduced. Conclusion:The powder and water decoction of sedimentary type Limonitum had definite and positive intervention effect on warfarin hemorrhage model rats，which could play a coagulation role by enhancing the vasoconstriction ability，promoting the activation of platelets，and increasing the platelet aggregation rate and blood viscosity. The metal elements such as Na，K，Ca，Fe，Li，Ti，V，Co，Cu，Zn，Ni and Sr may be the material basis for sedimentary type Limonitum to exert hemostatic effect. According to the above indicators，the intervention effect of powder group and decoction group was basically the same.

Metabolomics Analysis of Chloriti Lapis on Brain Tissue of PTZ-kindled Epileptic Rats / 中国实验方剂学杂志

Objective:To explore the possible mechanism of Chloriti Lapis in the treatment of epilepsy by the metabonomics of brain tissue in pentylenetetrazol （PTZ）-kindled epileptic rats treated with Chloriti Lapis. Method:The epileptic animal model in rats was established by PTZ kindling， and the rats were divided into the control group， model group， carbamazepine group and Chloriti Lapis group. The brain tissue samples were detected by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry（UPLC/Q-TOF-MS）， and the experimental results were statistically analyzed by partial least squares-discriminant analysis （PLS-DA） and SPSS 18.0. Result:The metabolic fingerprints and metabolic profiles of the rat brain tissue were established， which showed that the metabolic profiles of each group had changed significantly and could be separated well among the groups. Moreover， the Chloriti Lapis group had a tendency to be closer to the control group than the carbamazepine group. Seven differential metabolites were screened， including phosphatidylserine （PS） （18∶0/18∶0）， <italic>L</italic>-glutamic acid， docosahexaenoyl ethanolamide， arachidonic acid， glucosylsphingosine， cholestane-3，7，12，24，25-pentol and lysophosphatidylcholine （LysoPC） （P-18∶0）. Except for docosahexaenoyl ethanolamide and LysoPC （P-18∶0）， Chloriti Lapis had significant intervening and regulating effects on the other five differential metabolites. There were 12 possible metabolic pathways that affected the metabolic disorder of PTZ-kindled rats， and 3 important metabolic pathways （pathway impact>0.1）， namely， <italic>D-</italic>glutamine and <italic>D-</italic>glutamate metabolism， alanine， aspartate and glutamate metabolism， and arachidonic acid metabolism， among which <italic>D-</italic>glutamine and <italic>D-</italic>glutamate metabolism was the most important metabolic pathways. Conclusion:From this point of view， Chloriti Lapis has a clear intervention effect on PTZ-kindled epileptic rats， which may be related to the intervention of the above differential metabolite contents and related metabolic pathways. It can reduce the toxic effect of excitatory neurotransmitters on neurons in brain tissue and inhibit the development of inflammation in brain tissue， so as to maintain the biological function of brain cells and slow down the occurrence of epilepsy.

Metabonomics research on lung tissue of rats with acute exacerbation of chronic obstructive pulmonary disease treated with mineral Chinese medicine Chloriti Lapis / 中国中药杂志

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.

Effects of mineral Chinese medicine Chloriti Lapis on contents of metal elements in plasma and lung tissue of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) rats / 中国中药杂志

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.

Compared with the model group， the contents of Zn， Fe， K， Li， Co， As and Pb in brain tissue of rats in the Chloriti Lapis group were obviously increased （<italic>P</italic><0.05， <italic>P</italic><0.01）， while the contents of Sr and Sb were significantly decreased （<italic>P</italic><0.01）. These results showed that Chloriti Lapis had positive effect on the regulation of the content of metal elements in rat brain tissue to normal level， the intervention effect was clear， and the overall effect was better than that of carbamazepine group. The determination of 21 metal elements in plasma showed that compared with the blank group， the levels of K， Sr and Cd in the model group were significantly increased （<italic>P</italic><0.05）， and the contents of Li， Al， Ti and Cr were significantly decreased （<italic>P</italic><0.05）. Compared with the model group， the contents of Ca， K， Li， Al and V in the Chloriti Lapis group were obviously increased （<italic>P</italic><0.05， <italic>P</italic><0.01）， and the contents of Fe， Ti， Sr and Cd were significantly decreased （<italic>P</italic><0.05，<italic>P</italic><0.01）. The correlation analysis of metal elements among the groups showed that there were 17 pairs of elements had positively correlation in the brain tissue of rats， 2 pairs of elements had significant negative correlation. In the plasma of rats， 8 pairs of elements had significant positive correlation and 6 pairs of elements had significant negative correlation. Conclusion:The metal element groups represented by Zn， Fe， K， Li， Co， As， Pb， Sr， Sb， Ca， Al， V， Ti and Cd may be the effective material basis for Chloriti Lapis to interfere PTZ-kindled epileptic model rats， which may be related to the influence of these metal element groups on the release of neurotransmitters and the electrical balance of neurons， the regulation of abnormal synchronous discharge induced by Na⁺， K⁺， Ca²⁺ channel disorders and intervention of metabolism pathways in brain tissue related to epilepsy. It can make the excitatory and inhibitory activities restrain each other， and finally reach the normal physiological state of neurons and cells. The intervention effect of Chloriti Lapis group was better than that of carbamazepine group.

Mineral composition analysis and hemostatic effect of limonitum with different mineral genesis / 中国中药杂志

Models were established in mice with warfarin sodium method, and their bleeding time and hemostasis time were measured by tail cutting method and slide method respectively. Rats were administered for 15 consecutive days to measure their recalcification time, plasma viscosity, platelet adhesion rate, platelet aggregation rate and other blood indexes. As compared with the blank group, the bleeding time was prolonged in model groupn(P<0.05). As compared with the model group, the results showed that the positive vitamin K, the leaching type water decoction and the sediment type decoction could significantly shorten the bleeding time (P<0.01); positive vitamin K significantly (P<0.01) shortened clotting time, and the leaching type water decoction, the sediment type water decoction and the sediment type powder could also shorten the clotting time (P<0.05). As compared with blank group, low dose, medium dose of leaching type water decoction, medium dose of powder, high dose of sediment type decoction and low dose of drug residues could reduce plasma viscosity (P<0.05), and high dose of leaching powder and low dose of water decoction could significantly reduce (P<0.01) plasma viscosity. As compared with blank group, Limonitum leaching type decoction high dose group could significantly reduce the platelet adhesion rate (P<0.05), while sediment type water decoction could significantly increase the platelet adhesion rate (P<0.05); the high dose of leaching type water decoction, high dose of drug residues, low dose of leaching type powder and low dose of drug residues could decrease the platelet aggregation rate (P<0.05), while high dose of leaching type water decoction and high dose of the powder could increase the platelet aggregation rate (P<0.05). Analysis of mineral compositions was conducted by polarized light microscopy and X-ray diffraction (XRD). The results of the both methods showed that Limonitum mineral compositions contained goethite, quartz, and kaolinite, and sedimentary type also contained illite and albite. Sediment type of Limonitum showed better hemostatic effect, which may be related to the high content of goethite and illite.

Association between chemical composition of essential oil with penetration enhancement effect and drug properties of traditional Chinese medicine / 中国中药杂志

The results of previous studies showed potential correlations between the penetration enhancement effect of essential oils and the drug properties of traditional Chinese medicine based on the data mining method. As chemical composition is the material basis of drug properties of traditional Chinese medicine, this article further analyzed the correlation between the chemical composition of essential oils and the drug properties. Firstly, essential oils were extracted by steam distillation, and then physicochemical parameters of essential oils, such as relative density and refractive index, were measured. The chemical components of 20 essential oils were analyzed by GC-MS, and divided into 12 categories according to skeleton features and functional groups. Finally, Logistic regression analysis was applied to reveal the correlations. The results proved that five flavors, four tastes and channel tropisms showed the correlation with chemical composition of essential oils (P<0.05). In conclusion, there were obvious correlations and regularity between the drug properties of traditional Chinese medicine and the chemical composition of essential oils.

Association between penetration enhancement effect of essential oils and drug properties of traditional Chinese medicines by data mining method / 中国中药杂志

To study the association between penetration enhancement effect of essential oils and drug properties of traditional Chinese medicines. Through literature research, 34 kinds of essential oils with the penetration enhancement effect were collected. The methods of frequency analysis and variable crosstab were used for intuitive analysis and association analysis. The association between penetration enhancement effect of essential oils and drug properties (four natures, five flavors, channel tropism) were analyzed by a general linear model. According to the findings, the essential oils with penetration enhancement effect were all sourced from acrid traditional Chinese medicines, because their positive drug nature contributed to the enhancement of the penetration effect of essential oil; five flavors had little effect on penetration enhancement (P = 0.6982), but four natures and channel tropism showed significant effects (P = 0.011, 0.077). In conclusion, there were obvious association and regularity between penetration enhancement effect of essential oils and drug properties of traditional Chinese medicine.
