In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Objective To investigate the mechanism mediating the regulatory effect of lncRNA MAGI2-AS3 on cisplatin(DDP)resistance in non-small cell lung cancer(NSCLC).Methods MAGI2-AS3 and miR-1269a expression levels were detected by qRT-PCR in DDP-sensitive lung cancer cell lines(A549 and H1299)and their resistant counterparts(A549/DDP and H1299/DDP).In A549 and H1299 cells with MAGI2-AS3 silencing and A549/DDP and H1299/DDP cells overexpressing MAGI2-AS3,the effects of 20 μmol/L DDP on cell viability and apoptosis were examined with CCK-8 assay,colony formation assay,flow cytometry and Western blotting,and the changes in epithelial-mesenchymal transition(EMT)were assessed with wound healing and Transwell assays.The interaction between MAGI2-AS3,miR-1269a and PTEN was predicted using GEPIA,StarBase and miRDB and verified with luciferase reporter gene assay and radioimmunoprecipitation(RIP)assay.A miR-1269a mimic and pcDNA3.1-PTEN plasmid were used to perform the rescue assay.Results MAGI2-AS3 expression was significantly downregulated in lung cancer tissues(P<0.05)in association with a poor prognosis(P<0.05).In the two DDP-resistant lung cancer cell lines,MAGI2-AS3 expression was significantly lowered as compared with the sensitive cells.Silencing MAGI2-AS3 significantly enhanced cell viability and promoted EMT of A549 and H1299 cells irrespective of DDP treatment,and also decreased DDP-induced apoptosis of the cells.In A549/DDP and H1299/DDP cells,MAGI2-AS3 overexpression strongly repressed cell viability and EMT irrespective of DDP treatment and promoted DDP-induced cell apoptosis.Luciferase reporter gene and RIP assays confirmed the binding of MAGI2-AS3 with miR-1269a and the binding of miR-1269a with 3'-UTR domain of PTEN.The rescue assay demonstrated that MAGI2-AS3 acted as a sponge for miR-1269a to promote PTEN expression and downregulate AKT phosphorylation,thus inhibiting EMT and promoting DDP-induced apoptosis of A549/DDP cells.Conclusion MAGI2-AS3 enhances DDP sensitivity of NSCLC by targeted regulation of the miR-1269a/PTEN/AKT signaling axis.

Objective:This study analyzes the expression level of miR-1180-3p and constructs the regulatory network of relevant ceRNA by integrating the DNA methylation and gene expression profile of hepatocellular carcinoma from the Cancer Genome Atlas (TCGA).Methods:Firstly, the expression level of miR-1180-3p in hepatocellular carcinoma and adjacent tissues was analyzed by TCGA database, and the differential expression of lncrna and mRNA was screened. Secondly, the LncBase database and the TargetScan database were used to predict the relationship between miR-1180-3p and lncRNA and mRNA, and the DNA methylation-mediated lncRNA was screened by the DNA methylation profile of lncRNA. Finally, Cytoscape software was used to construct miR-1180-3p relevant ceRNA network, and WebGestalt website was used to perform GO and KEGG analysis of related mRNA in ceRNA.Results:Compared with patients with low expression of miR-1180-3p (mean overall survival duration, 5.69 ± 0.35 years), patients with high expression of miR-1180-3p had shorter overall survival time (mean overall survival duration, 3.99 ± 0.47 years), indicating that the high expression of miR-1180-3p was hepatocellular carcinoma risk factor affecting the prognosis ( HR = 1.28, 95% CI = 1.1 ~ 1.5, P < 0.01). A miR-1180-3p related ceRNA regulatory network was constructed in this study, which contained 2 lncRNAs (F11-AS1 and LINC01511) and 37 mRNAs. Conclusion:This study has successfully constructed miR-1180-3p relevant ceRNA regulatory network, and DNA methylation-mediated F11-AS1 and F11-AS1/miR-1180-3p/C11of54 ceRNA regulatory axis has played an important role in the occurrence and development of hepatocellular carcinoma.

ObjectiveTo explore the mechanism of the Wenyang Jieyu prescription in regulating depression-like behavior in mice after maternal-infant separation combined with secondary stress. MethodsAfter birth, the rats were randomly divided into blank (NC) group, maternal-infant separation (MS) group, restraint stress (RS) group, maternal-infant separation combined with restraint stress (MRS) group, Wenyang group, Jieyu group, Wenyang Jieyu (XSF) group, and minocycline group. Maternal-infant separation was performed on day 5 (PD5), followed by weaning at PD21 and prophylactic administration. The dose of Wenyang group, Xiaoyao group, XSF group and minocycline group were 5.85, 12.03, 16.71 g·kg-1 and 50 mg·kg-1, respectively. Restraint stress was applied on PD90. The model was evaluated using glucose, social interaction, open field, and O-maze behavior tests, as well as high-performance liquid chromatography to measure serotonin, dopamine, and other neurotransmitters. The expression level of ionized calcium-binding adaptor molecule-1 (Iba-1) protein, a marker of hippocampal microglia, was detected by immunohistochemistry. Protein expression levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in the hippocampus were analyzed by an automatic protein expression analysis system. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression levels of M1 markers, JAK2/STAT3 pathway-related genes, and cytokines in hippocampal microglia in each group. ResultsCompared with the NC group, the MRS group exhibited depression-like behavior, with significantly decreased levels of neurotransmitters in the hippocampus (P<0.05, P<0.01), increased expression of Iba-1 (P<0.01), and elevated protein levels of JAK2 and STAT3 (P<0.05). The mRNA expression levels of CD68, CD11b, IL-1β, JAK2, and STAT3 were significantly increased (P<0.01), while IL-10 mRNA expression was significantly decreased (P<0.01). Compared with the MRS group, the XSF and minocycline groups showed some improvement in depression-like behavior. In these groups, the hippocampal neurotransmitter content was significantly increased (P<0.05, P<0.01), and Iba-1 expression was significantly decreased (P<0.01). The protein levels of JAK2 and STAT3 in the XSF group showed a downward trend. The mRNA expression levels of CD68, CD11b, JAK2, STAT3, and IL-1β in the hippocampus were significantly decreased in the XSF and minocycline groups (P<0.05, P<0.01), while IL-10 mRNA expression was significantly increased (P<0.05, P<0.01). ConclusionWenyang Jieyu prescription can regulate depression-like behavior in maternal-infant separation mice combined with secondary stress by inhibiting the polarization of hippocampal microglia to the M1 phenotype. The regulation of hippocampal microglia polarization by Wenyang Jieyu prescription may be associated with the JAK2/STAT3 pathway.

ObjectiveTo explore the mechanism of Xiaoyaosan in alleviating lipopolysaccharide (LPS)-induced depressive-like behavior in mice based on the c-Jun N-terminal kinase (JNK) pathway. MethodAfter adaptive feeding, C57BL/6J mice were randomly divided into normal group, model group, minocycline group (intrabitoneal injection, 50 mg·kg-1), fluoxetine group (intragastric administration, 2.6 mg·kg-1), and low-, medium-, and high-dose Xiaoyaosan groups (intragastric administration,6.012 5, 12.025, and 24.050 g·kg-1). After 14 days of administration, the model group and each administration group were intraperitoneally injected with 2 mg·kg-1 LPS, and the normal group was intraperitoneally injected with equal volume of normal saline. Depressive-like behavior in mice was assessed using the open field test and the elevated zero maze test. High-performance liquid chromatography (HPLC) was used to measure the levels of norepinephrine (NE) and epinephrine (E) in the mouse hippocampus. Enzyme-linked immunosorbent assay (ELISA) was performed to determine serum interleukin-1β (IL-1β) levels. Immunohistochemistry was used to measure the protein expression levels of ionized calcium-binding adapter molecule-1 (Iba-1), c-Fos, and c-Jun. Real-time polymerase chain reaction (Real-time PCR) was used to measure mRNA expression levels of IL-1β, c-Jun, c-Fos, and JNK3 in the mouse hippocampus. Protein expression levels of JNK and phosphorylated (p)-JNK in the mouse hippocampus were measured using capillary protein automated protein expression analysis system (Western). ResultCompared with the normal group, the model group exhibited significantly reduced central area residence time, crossing times, and travel distance in the open field (P<0.01), significantly increased serum IL-1β levels (P<0.01), significantly decreased NE and E levels (P<0.05), upregulated mRNA expression of IL-1β, JNK3, and c-Fos, and increased protein expression of Iba-1, c-Fos, and c-Jun (P<0.05, P<0.01). Compared with the model group, the Xiaoyaosan groups showed increased central area residence time and open arm residence time (P<0.05), increased NE and E levels (P<0.01), decreased mRNA expression of IL-1β, JNK3, c-Jun, and c-Fos, and decreased protein expression of Iba-1, c-Fos, JNK, and p-JNK (P<0.05, P<0.01). The minocycline group and the fluoxetine group showed decreased mRNA expression of JNK3, c-Jun, and c-Fos (P<0.05, P<0.01). The minocycline group showed decreased serum IL-1β and p-JNK protein expression (P<0.01). The fluoxetine group exhibited increased NE and E levels and decreased c-Fos protein expression (P<0.01). ConclusionXiaoyaosan can improve depressive-like behavior induced by LPS in mice, and its mechanism may be related to the inhibition of neuroinflammatory responses and the JNK pathway.
