BACKGROUND:Ligustrazine can effectively prevent and treat peritoneal adhesion and adhesive ileus after surgical treatment. OBJECTIVE:To prepare Ligustrazine nanoparticle spray which is prepared to achieve sustained release and improve clinical efficacy and to explore its optimal dose for preventing experimental peritoneal adhesions in rats. METHODS:Eighty rats were randomly divided into five groups:model group, sodium hyaluronate group, high-, medium-and low-dose Ligustrazine nanoparticle groups, with 16 rats in each group. After peritoneal adhesion model was established with rasp method, model group was immediately subject to abdomen-closing, while sodium hyaluronate group and Ligustrazine nanoparticle groups received sodium hyaluronate smearing and Ligustrazine nanoparticle spray (2.5, 5, 10 mg/kg), respectively. Al rats were kil ed at 1 and 2 weeks after modeling, to observe adhesions. The adhesion score was recorded. The adhesive tissue sections were stained with hematoxylin-eosin for pathological changes. The level of transformation growth factor-β1 in peritoneal fluid of rats was detected with ELISA assay. RESULTS AND CONCLUSION:Ligustrazine Nanoparticle spray had a sustained release effect, and prolonged the duration of action of drugs, thus achieving a better anti-adhesion effect post-surgery. The medium-and high-dose Ligustrazine nanoparticle sprays exhibited better anti-adhesion effects, and improved the rise of transformation growth factor-β1 level in the peritoneal fluid. As the drug concentration is low, the intraperitoneal administration in a spray manner is preferred. Because the total dose is limited, we define the optimal effective dose as 5 mg/kg.

OBJECTIVE To establish the fingerprints of dried Houttuynia cordata and its decoction pieces ，conduct chemometrics analysis and determine the contents of 5 flavonoids such as neochlorogenic acid. METHODS High performance liquid chromatography （HPLC）method was adopted. Using quercitrin as reference ，HPLC fingerprints of 10 batches of dried H. cordata and its decoction pieces were drawn. The similarity evaluation was conducted by Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition），the common peaks were also confirmed. SIMCA-P 14.1 software was applied for principal component analysis （PCA）and partial least square-discriminant analysis （PLS-DA），and the variable importance in projection（VIP）value more than 1 was considered as a standard to screen the differential components affecting the quality of these two products ；meanwhile，the contents of 5 components such as neochlorogenic acid in both products were determined by the same HPLC method. RESULTS There were 20 common peaks in 10 batches of dried H. cordata and 10 batches of its decoction pieces with the similarity values more than 0.960. A total of 5 common peaks were identified ，which were neochlorogenic acid （peak 1）， chlorogenic acid （peak 3），cryptochlorogenic acid （peak 4），rutin（peak 7）and quercitrin （peak 11）. The results of PCA and PLS-DA showed that dried H. cordata could be distinguished from its decoction pieces obviously ；the common peaks with VIP value greater than 1 were as follows ：peak 7（rutin），peak 20，peak 5，peak 13，peak 2，peak 18，peak 3（chlorogenic acid ）， peak 14，peak 17 and peak 19. The linear range of neochlorogenic acid ，chlorogenic acid ，cryptochlorogenic acid ，rutin and quercitrin were 3.77-60.29 μg/mL（r＝0.999 7），1.40-22.42 μg/mL（r＝0.999 5），3.76-60.22 μg/mL（r＝0.999 9），2.19-35.06 μg/mL （r＝0.999 9）and 25.49-407.88 μg/mL（r＝0.999 7），respectively. RSDs of precision ，stability（24 h）and reproducibility E-mail：20190394@njucm.edu.cn tests were all lower than 3％. The average recoveries of the above components in these two products were 98.72％-101.12％ and 98.86％ -100.63％ with RSDs less than 3％（n＝9）. In dried H. cordata ，the average contents of 5 components were 0.87，0.33，0.59，0.61 and 6.17 mg/g，while the average contents were 0.42，0.11，0.26，0.23 and 3.16 mg/g in its decoction pieces ，respectively. CONCLUSIONS HPLC fingerprint and the method of content determination are stable and feasible ，which could be used for the quality control of dried H. cordata and its decoction pieces. Besides ，rutin and other components may be the differential components which could affect the quality of these two products ；the average contents of the 5 flavonoids such as neochlorogenic acid in dried H. cordata all decrease after processing.

OBJECTIVE To establish the method for monitoring the dynamic changes of odor components in Cornus officinalis during processing . METHODS The decoction pieces of C. officinalis with different processing time were prepared by the wine steaming method . The dynamic changes of odor components were obtained by using ultra -fast gas electronic nose ；odor components were identified by comparing with AroChemBase database ；the dynamic changes of odor compounds were analyzed in combination with peak area ，and the chemical pattern recognition analysis were carried out .

Eight odor components such as ethanol can be used as monitoring indicators of C. officinalis dring processing .

Objective:To screen the differentially expressed genes(DEGs)under high phosphate-induced calcification in the vascular smooth muscle cells(VSMCs)by mRNA high-throughput sequencing technology,and to analyze the key genes and signaling pathways involved in the VSMCs calcification.Methods:The human VSMCs were divided into control group and model group.The cells in model group was exposed to the high-phosphate medium,while the cells in control group were cultured in DMEM supplemented with 10%fetal bovine serum under the same conditions.The VSMCs in two groups,stably transfected,were cultured for 12 d.The morphology of the cells in two groups were observed and photographed under inverted microscope.The DEGs were selected by Hisat2 software,and Gene Ontology(GO)functional and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were performed by Stringtie software from three aspects,such as biological processes(BP),molecular functions(MF),and cellular components(CC).The calcification of the cells in two groups was observed by Von Kossa staining method.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to analyze the expression levels of alkaline phosphatase(ALP),bone morphogenetic protein 2(BMP2),alpha-smooth muscle actin(α-SMA),tumor protein 53(Tp53),glutathione peroxidase 4(GPX4),ferritin light chain 1(Ftl1),and glycosylphosphatidylinositol-specific phospholipase D1(GPLD1)mRNA in the cells in two groups.Results:Compared with control group,there were 2 524 DEGs in the cells in model group,and there were 1 368 upregulated DEGs and 1 156 downregulated DEGs.Clustering of DEGs between the cells in two groups was distinct.The GO functional and KEGG pathway enrichment analysis results showed that the upregulated DEGs were primarily involved in regulating the microtubule cytoskeleton,cell polarity,protein localization,and cell cycle regulation among BPs;in constructing cell membrane,microtubule organization,chromosomes,and kinetochore among CCs;and functioning in phosphatidylinositol phosphate,Rho GTPase protein binding,transmembrane transport,and protein kinase regulatory activity among MFs.Downregulated DEGs were mainly involved in cytoplasmic translation,protein membrane localization,mRNA metabolism,and protein endoplasmic reticulum localization among BPs;in forming ribosome subunits,cell membrane,and autophagy among CCs;and functioning in single-stranded DNA,ribonucleoprotein complex,growth factor binding,regulating protein kinase activity,and catalytic activity among MFs.Seven signaling pathways were significantly enriched in upregulated genes,most notably in the biosynthesis of glycosylphosphatidylinositol(GPI)anchors;whereas 18 signaling pathways were significantly enriched in the downregulated genes,most notably in ferroptosis.The RT-qPCR results showed that compared with control group,the expression levels of GPX4,Ftl1,and Tp53 mRNA in the cells in model group were significantly decreased(P<0.01),while the expression level of GPLD1 mRNA was significantly increased(P<0.01);compared with control group,the expression level of α-SMA mRNA in the cells in model group was significantly decreased(P<0.01),and the expression levels of ALP and BMP2 mRNA were significantly increased(P<0.01).Conclusion:The VSMCs underwent calcification and normal cells exhibit the DEGs.The key signaling pathways in the calcification induced by high phosphate in the VSMCs include ferroptosis and GPI anchor biosynthesis,mediated primarily through GPX4,Ftl1,Tp53,and GPLD1.
