Metabolomics Analysis of Plasma at Different Stages Based on UPLC-Q-TOF/MS： Modeling of Spleen Deficiency with Dampness Retention-ulcerative Colitis Rats and Administration of Shenling Baizhusan / 中国实验方剂学杂志

ObjectiveBased on ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF/MS）， the changes of endogenous markers in rat plasma at the different stage， namely modeling and administration of Shenling Baizhusan （SLBZS）， and the mechanism of SLBZS in the treatment of ulcerative colitis （UC） were studied. MethodIn the modeling stage， rats were randomly divided into normal group， spleen deficiency with dampness retention-UC （SDDR-UC） and pure-UC （P-UC） model group. In the administration stage， SLBZS was given to the above two different model groups. After modeling and administration， rat plasma was collected and determined by UPLC-Q-TOF/MS. The mobile phase was 0.1% formic acid aqueous solution （A）-acetonitrile （B） for gradient elution （in positive ion mode：0-2 min， 99%A； 2-9 min， 99%-73%A； 9-10 min， 73%-44%A； 10-13 min， 44%-38%A； 13-19 min， 38%-28%A； 19-21 min， 28%-2%A； 21-23 min， 2%A； 23-25 min， 2%-10%A； 25-27 min， 10%-99%A； in negative ion mode：0-2 min， 85%A； 2-3 min， 85%-65%A； 3-5.5 min， 65%-44%A； 5.5-8 min， 44%-25%A； 8-10 min， 25%-2%A； 10-16 min， 2%-85%A）. The electrospray ionization （ESI） temperature was 120 ℃ under the positive and negative ion modes， and the acquisition range was 50-1 000. Partial least squares-discriminant analysis （PLS-DA） was used to analyze the changes of endogenous metabolites in the above two different model rats from the different stage. MetaboAnalyst 5.0 was used to analyze the metabolic pathways of these identified metabolites. ResultSixteen potential biomarkers were screened and identified in the modeling stage， among which 11 potential biomarkers were common in the two model rats， which mainly affected the primary bile acid biosynthesis pathway. Twenty-three potential biomarkers were screened and identified during the administration stage， among which 3 potential biomarkers were shared by the two model rats， and SDDR-UC and P-UC model rats had 11 and 9 potential biomarkers， respectively. It mainly affected 6 pathways such as purine metabolism， pentose phosphate pathway， pyrimidine metabolism， retinol metabolism， primary bile acid biosynthesis and steroid hormone synthesis. ConclusionThe primary bile acid biosynthesis pathway appears in the different stage of modeling and administration of UC， showing a dynamic change process. The therapeutic effect of SLBZS on SDDR-UC rats may be related to inhibiting the expression of nuclear transcription factor -κB （NF-κB） signaling pathway， activating farnesoid X receptor （FXR） and enhancing the expression of cytochrome P450.

Study on the Mechanism of Gegen Qinlian Decoction for Lowering Blood Lipids and Preventing Blood Glucose Increase Based on Intestinal Flora / 中国药房

OBJECTIVE：To study the ef fects of Gegen qinlian decoction （GGQLD）on blood lipid and blood glucose of hyperlipidemia（HLP）model rats ，and to explore its mechanism from the perspective of intestinal flora. METHODS ：Totally 48 rats were randomly divided into blank control group （n＝8）and modeling group （n＝40）. For consecutive 5 weeks，model group was given high-lipid diet to induce HLP model ；blank control group was given routine diet. After modeling ，30 modeling rats were randomly divided into model group ，simvastatin group （positive control ，10 mg/kg），GGQLD high-dose ，medium-dose and low-dose groups （14.85，4.95，1.65 g/kg，by crude drug ），with 6 rats in each group. Blank control group and model group were given constant volume of normal saline intragastrically ；administration groups were given relevant medicine intragastrically ，once a day，for consecutive 11 weeks. At the same time ，each group was continuously given corresponding diet. After the last medication ， body mass and body length of rats were determined ，and Lee ’s index was calculated. Serum levels of TG ，TC，HDL-C，LDL-C and fasting blood glucose （FBG）were determined in rats. DNA of rat caecum content was extracted for 16S rRNA V 3-V4 region sequencing. The Two-part model was used to analyze the correlation between intestinal flora with lipids and blood glucose. RESULTS：After 11 weeks of administration ，compared with blank control group ，the body mass ，body length ，Lee’s index ， serum levels of TC ，TG，HDL-C and FBG of model group were increased significantly （P＜0.05 or P＜0.01），while the level of HDL-C was decreased significantly （P＜0.05）. Compared with model group ，body mass and Lee ’s index and serum levels of TG ， FBG of rats in GGQLD high-dose group ，and serum levels of TC ，TG in GGQLD medium-dose group ，as well as serum level of TG of rats in GGQLD low-dose group was decreased significantly （P＜0.05 or P＜0.01）. Correlation analysis with intestinal flora showed that TC and TG shared 3 operational taxonomic units （OTU），including OTU 559，OTU701 and OTU 135（OTU135 was also shared with FBG ），which were all positively correlated with the level of TC ，TG and FBG （P＜0.01）. The three OTU were annotated as Tyzzerella of Spirillaceae ，Anaerotruncus of Verrucaceae and Peptoclostridium of Streptococcidae ，respectively. High-dose and low-dose GGQLD had a down-regulating effect on Tyzzerella and Anaerotruncus（P＜0.05 or P＜0.01），while had up-regulating effect on Peptoclostridium（P＜0.01）. CONCLUSIONS ：High-dose GGQLD （14.85 g/kg）can effectively reduce the body mass and blood lipid of HLP model rats ，and can prevent the abnormal increase of blood glucose of model rats. The mechanism may be associated with that the reduction of intestinal flora （Tyzzerella，Anaerotruncus）content.
