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.

Objective     To investigate the current status of constipation during postoperative hospitalization and the factors associated with moderate to severe constipation at discharge in lung cancer patients. Methods     Lung cancer patients who underwent surgery in 6 tertiary hospitals in Sichuan Province from November 2017 to January 2020 were enrolled. The MD Anderson Symptom Scale-Lung Cancer Module was used to collect postoperative constipation scores. Unconditional logistic stepwise regression was used to analyze the related influencing factors for moderate to severe constipation on the day of discharge. Results     Finally 337 patients were collected. There were 171 males and 166 females, with an average age of 55.0±10.3 years. Constipation scores of lung cancer patients increased from postoperative day 1 to day 3, and showed a decreasing trend from day 3 to day 7. Moderate to severe constipation was present in 68 (20.2%) patients at discharge. The postoperative hospital stay (OR=0.743, P<0.001) and the dose of morphine used during postoperative hospitalization (OR=1.002, P=0.015) were influencing factors for moderate to severe constipation at discharge in lung cancer patients. Conclusion    Lung cancer patients have the most severe constipation on postoperative day 3. Moderate to severe constipation at discharge is associated with the postoperative hospital stay and the dose of morphine used during postoperative hospitalization.

ObjectiveTo explore the mechanism of Qihuang Yiqi Shexue prescription （QHYQSX） in the treatment of immune thrombocytopenia （ITP） model mice based on the autophagy mediated by the adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR）/Unc-51-like kinase 1 （ULK1） signaling pathway. MethodFifty BALB/c mice were randomly divided into normal group， model group， high- and low-dose QHYQSX groups， and prednisone group， with 10 mice in each group. The ITP model was induced by intraperitoneal injection of anti-platelet serum （APS） of guinea pig. On the 8th day of the APS injection， drugs were administered by gavage for 14 days. Peripheral blood platelet （PLT） count and hemoglobin （Hb） concentration were detected. Spleen and thymus were separated， weighed， and the organ index was calculated. Sternum was sampled for bone marrow smear， and bone marrow megakaryocytes were classified under a microscope. Thrombopoietin （TPO）， interleukin-6 （IL-6）， IL-10， tumor necrosis factor-α （TNF-α）， transforming growth factor-β₁ （TGF-β₁）， and interferon-γ （IFN-γ） in the serum were detected by enzyme-linked immunosorbent assay（ELISA）. AMPK， mTOR， ULK1， microtubule-associated protein light chain 3 （LC3）， Beclin1， and p62 mRNA expression levels in the spleen were detected by Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR）. The protein expression of AMPK， p-AMPK， p-mTOR， p-ULK1， LC3Ⅱ/LC3Ⅰ， Beclin1， and p62 in the spleen was detected by Western blot. ResultCompared with the normal group， the model group showed reduced peripheral blood PLT count， Hb， and TPO levels （P<0.05，P<0.01）， increased spleen and thymus indexes （P<0.01）， decreased number of bone marrow megakaryocytes （P<0.01）， elevated serum levels of IL-6， TNF-α， and IFN-γ （P<0.01）， and reduced IL-10 and TGF-β₁ levels （P<0.01）. Compared with the model group， the groups with drug intervention showed increased PLT counts and TPO levels （P<0.01）， decreased spleen and thymus indexes （P<0.05， P<0.01）， elevated number of bone marrow megakaryocytes （P<0.05， P<0.01）， reduced serum levels of IL-6， TNF-α， and IFN-γ （P<0.05， P<0.01）， and up-regulated IL-10 and TGF-β₁ levels （P<0.05，P<0.01）. Compared with the low-dose QHYQSX group， the high-dose QHYQSX group and the prednisone group showed different degrees of significant differences in improving PLT counts and levels of cellular inflammatory factors （P<0.05， P<0.01）. Real-time PCR and Western blot results showed that compared with the normal group， the model group showed up-regulated mRNA expression of AMPK， LC3， and Beclin1 and protein expression of p-AMPK/AMPK， LC3Ⅱ/LC3Ⅰ， and Beclin1 in the spleen （P<0.05， P<0.01）， and down-regulated mRNA expression of mTOR， ULK1， and p62 and protein expression of p-mTOR， p-ULK1， and p62 （P<0.05， P<0.01）. Compared with the results in the model group， high- and low-dose QHYQSX and prednisone could down-regulate the mRNA expression of AMPK， LC3， and Beclin1 and protein expression of p-AMPK/AMPK， LC3Ⅱ/LC3Ⅰ， and Beclin1 in the spleen （P<0.05， P<0.01）， and up-regulate the mRNA expression of mTOR， ULK1， and p62 and protein expression of p-mTOR， p-ULK1， and p62 （P<0.05， P<0.01）. ConclusionQHYQSX may inhibit excessive autophagy by regulating the AMPK/mTOR/ULK1 signaling pathway， thereby regulating immune intolerance and playing a role in the treatment of ITP.

Objective:To study the different effects of pre-pregnancy obesity (PO), excessive gestational weight gain (EGWG), pre-pregnancy obesity combined with excessive gestational weight gain (PO+EGWG) of maternal rats on glucose and lipid metabolism in neonatal offspring, and to explore the possible mechanisms.Methods:Animal models of PO, EGWG and PO+EGWG were established by feeding SD rats with high-fat diets at different periods. Thirty-six SD rats were randomly divided into four groups, with nine rats in each group. The control group had a normal diet before and during pregnancy. The PO group had a high-fat diet before pregnancy and a normal diet during pregnancy. The EGWG group had a normal diet before pregnancy and a high-fat diet during pregnancy. And the PO+EGWG group had a high-fat diet before and during pregnancy. The body weight of maternal rats before and during pregnancy and the birth weight of neonatal rats were recorded. Nine male neonatal rats in each group were selected, fasting blood glucose levels were detected by glucometer, fasting insulin levels were detected by enzyme-linked immunosorbent assay kit, hepatic triglyceride and cholesterol levels were detected by glycerol phosphate oxidase-peroxidase method, hepatic lipid deposition were observed by hematoxylin-eosin staining and oil red O staining. The mRNA levels of hepatic key genes in glucose metabolism pathway IR, IRS, AKT and lipid metabolism FASN, SREBP1c, PPARα were detected by reverse transcription-polymerase chain reaction analyses.Results:The pre-pregnancy weight of maternal rats in high-fat diet group before pregnancy (PO group and PO+EGWG group) was significantly higher than those in normal diet group (control group and EGWG group). The percentage of weight gain of maternal rats in high-fat diet group during pregnancy (EGWG group and PO+EGWG group) was significantly higher than those in normal diet group (control group and PO group) ( P<0.05). The birth weight of neonatal rats in PO group, EGWG group and PO+EGWG group were significantly higher than that in control group ( P<0.05), and the birth weight of neonatal rats in PO+EGWG group was the largest. The fasting glucose, insulin level and insulin resistance index of newborn rats in PO, EGWG and PO+EGWG groups were higher than those in the control group, and the mRNA levels of IR, IRS and AKT were lower than those in the control group, but the differences were not statistically significant ( P>0.05). The hepatic triglyceride and cholesterol contents and mRNA levels of FASN and SREBP1c were higher in the EGWG and PO+EGWG groups than those in the control group, and the mRNA level of PPARα was higher in the PO+EGWG group than in the control and PO groups, with statistically significant differences ( P<0.05). Conclusions:Animal models of PO, EGWG and PO+EGWG were successfully constructed by feeding SD rats with high-fat diets before pregnancy, during pregnancy, before and during pregnancy. PO+EGWG had the most significant effects on the birth weight and glucose and lipid metabolism in neonatal offspring. Compared with EGWG, PO had a relatively significant effect on glucose metabolism in neonatal offspring. And compared with PO, EGWG had a relatively significant effect on lipid metabolism in neonatal offspring. The effects of maternal obesity on glucose and lipid metabolism in neonatal offspring were considered to be related to the expression changes of genes in glucose and lipid metabolism.

Objective To study the effects of diterpene ginkgolides meglumine injection ( DGMI) on memory impairment, activation of microglia and astrocytes and inflammatory cytokines in aged mice. Methods Twenty aged mice (22 months old) were randomly divided into two groups:aged mouse group(n=10) and DGMI group(n=10). Another 10 mice (2 months old) were selected as young mouse control group. The mice in DGMI group were received 5 mg/kg DGMI per day by tail vain injection for 4 weeks. The mice in the other two groups were received the same amount normal saline for 4 weeks. The Morris water maze was used to evaluate the function of spacial learning and memory after administration of drugs. The ex-pression of CD11b,GFAP,IL-1β,IL-6,TNF-α and NFκB in mice brain hippocampus were detected by West-ern blot. Results (1) The escape latency time of aged mouse group was significantly longer than that of young mouse control group from the 2nd day to the 7th day(P<0. 01). The times of platform crossing,time and distance in target quadrant of aged mouse group were significantly shorter than those of young mouse group (all P<0. 01). Compared with aged mouse group,DGMI significantly reduced the escape latency time of DGMI group (P<0. 01). DGMI increased the times of platform crossing,time and distance in target quad-rant of aged mouse group (P<0. 01). (2) The expressions of CD11b,GFAP in young mouse control group, aged mouse group and DGMI group were as follows respectively:CD11b:(1. 036±0. 023),(1. 757±0. 046), (1. 214±0. 024);GFAP:(1. 022±0. 071),(1. 344±0. 021),(1. 086±0. 073). DGMI reduced the expres-sion of CD11b and GFAP in hippocampus compared with aged mouse group ( t=5. 556,P<0. 01;t=5. 484, P<0. 01). (3) The expressions of IL-1β,IL-6,TNF-α and NFκB in young mouse control group,aged mouse group and DGMI group were as follows respectively:IL-1β:( 1. 003 ± 0. 057),( 2. 062± 0. 105),( 1. 182± 0. 084);IL-6:(1. 018±0. 024),(1. 583± 0. 052),( 1. 152± 0. 031); TNF-α:( 1. 021± 0. 054),(1. 449± 0. 053),(1. 211±0. 036);p-NFκB:(1. 052±0. 034),(1. 782± 0. 113),( 1. 158± 0. 066). DGMI reduced the expression of p-NFκB(t=6. 547,P<0. 01) and pro-inflammatory cytokines including IL-1β(t=8. 513,P<0. 01),IL-6(t=3. 421,P<0. 01) and TNF-α( t=5. 562,P<0. 01) in hippocampus compared with aged mouse group. Conclusion DGMI can improve the ability of learning and memory in aged mice. The mecha-nism may be related with inhibiting activity of microgliosis,astrocytosis,NFκB and neuroinflammaton.
