RESUMEN
@#Abstract: Inflammatory bowel disease (IBD), whose pathogenesis remains elusive, is a group of autoimmune diseases characterized by chronic, progressive, and lifelong inflammation of the digestive tract. The pathogenesis of IBD remains elusive. Although a number of drugs have been developed to treat IBD, their effects are merely anti-inflammatory. In addition, current treatments for IBD are easily susceptible to resistance in clinical practice. Mesenchymal stem cells (MSCs) have been reported to have the ability to migrate to the site of inflammation, with potent immunoregulatory effects, and to rebalance the immune microenvironment and restore the integrity of the epithelial barrier with significant value of application, particularly for patients who are refractory to classic medicines. In this paper, we reviewed the clinical applications, mechanisms and engineerable properties of MSC products and their exosomes to provide some reference for the use of MSCs and their exosomes in the treatment of IBD.
RESUMEN
Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

Objective To explore the clinical application of individualized coil embolization in the interventional treatment of renal artery aneurysm(RAA).Methods Data of 23 patients with RAA treated by individualized coil embolization were analyzed.There were 27 RAAs,in which narrow-necked RAAs were treated with coil embolization and wide-necked RAAs were treated with stent-assisted coil embolization.The efficacy of the two embolization methods were analyzed and the changes of renal function and symptoms were observed.Results A total of 27 RAAs in 23 patients were successfully embolized at one time,including 23 narrow-necked RAAs in 19 cases treated with coil embolization and 4 wide-necked RAAs in 4 patients treated with stent-assisted coil embolization.The embolization effect of 20 cases(86.96%)reached Raymond grade Ⅰ,and 3 cases(13.04%)reached gradeⅡ.Postoperative computed tomography angiography(CTA)showed that all parent arteries were patent,the RAA was not visualized,and there was no renal infarction.There was no statistical difference in creatinine values before operation,1 month,6 months and 1 year after operation(P>0.05).In the 12 patients with hypertension,there were statistically significant differences in blood pressure at 1 year after operation compared with preoperative,1 month,and 6 months after operation(P<0.05).The symptoms of low back pain and hematuria disappeared after operation.Conclusion Individualized coil embolization for RAA is safe,effective and worthy of clinical promotion.
RESUMEN
Objective:To evaluate the relationship between red blood cell distribution width (RDW) and prognosis of patients with hepatocellular carcinoma (HCC) andergoing transcatheter arterial chemoembolization (TACE).Methods:Clinical data of 212 patients with HCC andergoing TACE for the first time in Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2011 to May 2018 were retrospectively analyzed, including 184 males and 28 females, aged (56.8±11.2) years. Follow-up for survival. X-tile software was used to determine 13.1% as the optimal threshold for preoperative RDW prediction of prognosis, and enrolled patients were divided into a low level group (RDW<13.1%, n=70) and a high level group (RDW≥13.1%, n=142). Aspartate aminotransferase, total bilirubin, albumin, hemoglobin and lipoprotein a, Barcelona clinical liver cancer (BCLC) stage and other indexes were compared between the two groups. Survival analysis was performed by Kaplan-Meier method, survival rate was compared by log-rank test, and the effect of RDW on prognosis was analyzed by Cox regression. Results:The 1-year, 2-year and 3-year cumulative survival rates in RDW high level group were 34.5%, 14.1% and 6.3%, respectively, while those in RDW low level group were 64.3%, 38.6% and 21.4%, respectively, with significant difference ( χ2=23.09, P<0.001). Compared with the low level group, the levels of aspartate aminotransferase and total bilirubin were higher, the levels of albumin, hemoglobin and lipoprotein a were lower, the proportion of portal vein cancer thrombin was higher, and the stage of BCLC was later, with statistical significance (all P<0.05). Cox regression analysis showed that HCC patients with RDW≥13.1%( HR=1.732, 95% CI: 1.223-2.452, P=0.002) had poor survival prognosis after TACE. Conclusion:Preoperative RDW≥13.1% is an independent risk factor for survival after TACE in patients with HCC. RDW has potential predictive value for prognosis of patients with HCC.
RESUMEN
Chronic active Epstein-Barr virus (CAEBV) infection with renal involvement is not common. The paper reported a child of multisystem-compromised CAEBV infection with the onset of IgA nephropathy (IgAN). The child presented with intermittent gross hematuria, and renal biopsy showed focal proliferative IgAN, administered methylprednisolone pulse followed by oral prednisolone treatment. Intermittent increase of blood Epstein-Barr virus (EBV) load and abnormal EBV antibody, pneumonia caused by EBV and Staphylococcus aureus-mixed infection, periappendiceal abscess, and pancytopenia occurred during treatment follow-up. The CAEBV infection was considered. Echocardiography suggested pulmonary hypertension. Head CT presented multiple calcifications in the bilateral basal ganglia. Bone marrow biopsy showed bone marrow EBV-DNA 6.5×10 3 copies per liter. Immunohistochemistry of renal biopsy showed about 50 CD8 + (scattered +) cells per high power field (HPF), about 40 CD4 + (focal +) cells per HPF (local), CD68 + (-), latent membrane protein 1 (-), EBV-encoded small RNA (scattered +) approximately 25 cells per HPF. The lymphocyte subsets infected with EBV showed CD4 + T cells EBV-DNA 3.4×10 4 copies per 1 million cells, CD8 + T cells EBV-DNA 3.3×10 5 copies per 1 million cells, B cells EBV-DNA 1.25×10 4 copies per 1 million cells, NK cells/NK T cells EBV-DNA 2.3×10 4 copies per 1 million cells.

The patient currently receives oral prednisone treatment, and it is recommended to undergo hematopoietic stem cell transplantation and treatment is under follow up.
RESUMEN
ObjectiveTo explore the potential influencing factors and complex pathways affecting rehabilitation effect for children with autism spectrum disorder (ASD) from the perspective of parental efficacy in doctor-patient communication, and to provide evidence for improving the quality of rehabilitation service for children with ASD. MethodsAn anonymous face-to-face questionnaire survey was conducted to collect general demographic information of parents of children with ASD at designated rehabilitation institutions in Gansu province. The data included parental efficacy in doctor-patient communication, parental compliance of treatment and children's rehabilitation outcomes were collected. A structural equation model was used to explore the impact mechanism of parental communication efficacy on the rehabilitation outcomes of children with ASD. ResultsData from 519 parents at 37 rehabilitation institutions across 13 cities/counties in Gansu province were collected. Significant positive correlations were found between parental efficacy in doctor-patient communication, doctor-patient relationships, parental compliance with treatment and rehabilitation outcomes for children with ASD (P < 0.05). Through structural equation model analysis, the standardized direct effect of children with ASD from parents' doctor-patient communication efficacy was 0.151 (P = 0.023). The mediating effect of doctor-patient relationship and parental compliance with treatment were 0.160 (P = 0.001) and 0.111 (P = 0.001), respectively, with a chained mediating effect of 0.035 (P = 0.001). The pathway "parental efficacy in doctor-patient communication → doctor-patient relationship → ASD child's rehabilitation outcome" accounted for the highest proportion of the total mediating effect, at 52.29%. ConclusionParental doctor-patient communication efficacy may positively impact on the rehabilitation outcomes of children with ASD directly, and indirectly through the doctor-patient relationship and parental compliance with treatment. Rehabilitation institutions should focus on fostering parental communication skills and enhancing high-quality and humanized rehabilitation services.
RESUMEN
This study aimed to investigate the mechanism of Jiu Wei Bu Xue Oral Liquid on insomnia rats combining the methods of network pharmacology, molecular docking and experimental verification. UPLC-Q-TOF-MS/MS method and TCMIP, TCMSP databases were used to collect the ingredients and targets of Jiu Wei Bu Xue Oral Liquid. Protein-protein interactions and network analysis were performed to screen the key network targets and putative active ingredients of Jiu Wei Bu Xue Oral Liquid in treatment of insomnia, and then following by biological function and KEGG pathway analysis. Then binding ability for key network targets and putative active ingredients were predicted with molecular docking. The prediction targets were validated in para-chlorophenylalanine (PCPA) induced insomnia rats with administration of Jiu Wei Bu Xue Oral Liquid (2, 4, 8 mL·kg-1) for 7 days. Pentobarbital sodium induced sleeping test were performed to evaluate the synergistic sleep-aiding effect of Jiu Wei Bu Xue Oral Liquid. Then glutamic acid (Glu), γ-aminobutyrate (GABA) content and glutamate decarboxylase 1 (GAD67) activity in hypothalamus or hippocampus were evaluated, and the expressions of GAD67, γ-aminobutyric acid receptor subunit α1 (GABRA1) and γ-aminobutyric acid receptor subunit β2 (GABRB2) in hippocampus were detected by qRT-PCR and Western blot methods. Animal experiments were approved by the Institutional Committee on Animal Care of Guangxi Institute of Chinese Medicine & Pharmaceutical Science (the number of permission: 2022060802). Results showed that 16 key network targets and 16 putative active ingredients were obtained by analyzing the herbs-ingredients-targets network of Jiu Wei Bu Xue Oral Liquid in treatment of insomnia. Network pharmacology and molecular docking all indicated these active ingredients, for example atractylenolide Ⅲ, showed better binding ability with GABRA1 and GABRB2. Animal study indicated that, compared to PCPA-induced insomnia model, Jiu Wei Bu Xue Oral Liquid remarkably shortened the sleeping latency and increased the sleeping duration, increased GAD67 activity and the production of GABA in hippocampus of insomnia rats, as well as the expressions of GAD67, GABRA1 and GABRB2, while decreased Glu content in hypothalamus, leading to decreasing of Glu/GABA ratio and recovery of Glu-GABA balance. These results indicated that Jiu Wei Bu Xue Oral Liquid improved insomnia symptoms and helped maintain the Glu-GABA balance within hypothalamus and hippocampus, and reduced the excitatory neurotoxicity within brain. The mechanism may due to the elevation of GAD67 expression and enzyme activity, and the enhancement of type-A GABA receptor (GABAAR)-mediated neurons inhibition.
RESUMEN
ObjectiveTo investigate the effect of Chaihu Guizhitang on triple-negative breast cancer (TNBC) cells based on hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor A (VEGFA) signaling pathway. MethodTNBC xenograft model was established and the cells were randomized into model group, capecitabine group (0.2 mg·kg-1), Chaihu Guizhitang low-dose group, medium-dose group, and high-dose group (10.62, 21.23, 42.46 g·kg-1), with 10 mice in each group. After 21 days of medication, the content of tumor necrosis factor-α (TNF-α) in serum was detected by enzyme-linked immunosorbent assay (ELISA). The expression of HIF-1α mRNA was detected by real-time fluorogenic quantitative polymerase chain reaction (real-time PCR). Immunohistochemistry (IHC) was employed to detect the expression of HIF-1α, TNF-α, and VEGFA in tumor tissues, and CD34 staining to examine the angiogenesis in tumor tissues. Microvessel density (MVD) was calculated, and the protein expression of HIF-1α, VEGFA, and epidermal growth factor receptor (EGFR) in tumor tissues was measured by Western blot. ResultCompared with the model group, the rest four groups showed low levels of TNF-α (P<0.01), HIF-1α mRNA (P<0.01), expression of HIF-1α, TNF-α, VEGFA, and CD34 in cells, and MVD (P<0.05, P<0.01), and low protein levels of HIF-1α, VEGFA, and EGFR (P<0.01). Compared with capecitabine group, medium-dose and high-dose Chaihu Guizhitang decreased the level of TNF-α (P<0.01), HIF-1α mRNA (P<0.01), expression of HIF-1α, TNF-α, and VEGFA in cells (P<0.01), CD34 expression, MVD, and protein levels of HIF-1α, VEGFA, and EGFR (P<0.01). ConclusionChaihu Guizhitang may inhibit the angiogenesis in TNBC cells by regulating the expression of HIF-1α/VEGFA signaling pathway, thus exerting anti-tumor effect.

OBJECTIVE@#To analyze the characteristics and prognosis of acute leukemia(AL) with SET-NUP214 fusion gene.@*METHODS@#The clinical data of 17 patients over 14 years old newly diagnosed with SET-NUP214 positive AL admitted in Institute of Hematology and Blood Diseases Hospital from August 2017 to May 2021 were analyzed retrospectively.@*RESULTS@#Among the 17 SET-NUP214 positive patients, 13 cases were diagnosed as T-ALL (ETP 3 cases, Pro-T-ALL 6 cases, Pre-T-ALL 3 cases, Medullary-T-ALL 1 case), AML 3 cases (2 cases M5, 1 case M0) and ALAL 1 case. Thirteen patients presented extramedullary infiltration at initial diagnosis. All 17 patients received treatment, and a total of 16 cases achieved complete remission (CR), including 12 cases in patients with T-ALL. The total median OS and RFS time were 23 (3-50) months and 21 (0-48) months, respectively. Eleven patients received allogeneic hematopoietic stem cell transplantation(allo-HSCT), with median OS time of 37.5 (5-50) months and median RFS time of 29.5 (5-48) months. The median OS time of 6 patients in chemotherapy-only group was 10.5 (3-41) months, and median RFS time of 6.5 (3-39) months. The OS and RFS of patients with transplantation group were better than those of chemotherapy-only group (P=0.038). Among the 4 patients who relapsed or refractory after allo-HSCT, the SET-NUP214 fusion gene did not turn negative before transplantation. While, in the group of 7 patients who have not relapsed after allo-HSCT till now, the SET-NUP214 fusion gene expression of 5 patients turned negative before transplantation and other 2 of them were still positive.@*CONCLUSION@#The fusion site of SET-NUP214 fusion gene is relatively fixed in AL patients, often accompanied by extramedullary infiltration. The chemotherapy effect of this disease is poor, and allo-HSCT may improve its prognosis.

Aurora kinase A (Aurora-A), a serine/threonine kinase, plays a pivotal role in various cellular processes, including mitotic entry, centrosome maturation and spindle formation. Overexpression or gene-amplification/mutation of Aurora-A kinase occurs in different types of cancer, including lung cancer, colorectal cancer, and breast cancer. Alteration of Aurora-A impacts multiple cancer hallmarks, especially, immortalization, energy metabolism, immune escape and cell death resistance which are involved in cancer progression and resistance. This review highlights the most recent advances in the oncogenic roles and related multiple cancer hallmarks of Aurora-A kinase-driving cancer therapy resistance, including chemoresistance (taxanes, cisplatin, cyclophosphamide), targeted therapy resistance (osimertinib, imatinib, sorafenib, etc.), endocrine therapy resistance (tamoxifen, fulvestrant) and radioresistance. Specifically, the mechanisms of Aurora-A kinase promote acquired resistance through modulating DNA damage repair, feedback activation bypass pathways, resistance to apoptosis, necroptosis and autophagy, metastasis, and stemness. Noticeably, our review also summarizes the promising synthetic lethality strategy for Aurora-A inhibitors in RB1, ARID1A and MYC gene mutation tumors, and potential synergistic strategy for mTOR, PAK1, MDM2, MEK inhibitors or PD-L1 antibodies combined with targeting Aurora-A kinase. In addition, we discuss the design and development of the novel class of Aurora-A inhibitors in precision medicine for cancer treatment.
RESUMEN
Objective To discuss the application value of liver shear wave velocity(SWV)and its correlation with portal vein pressure in evaluating the efficacy of interventional therapy for Budd-Chiari syndrome(BCS).Methods The clinical data of 40 BCS patients,who were admitted to the Affiliated Hospital of Xuzhou Medical University of China to receive treatment between April 2020 and April 2022,were collected.During interventional procedure,the hepatic venous pressure gradient(HVPG)was determined separately before and after recanalization of the treated vessels,the liver SWV was determined at one day before,2 days,1 month and 3 months after the treatment,and the above indexes were statistically analyzed.Results Successful initial interventional therapy was accomplished in all patients.The preoperative one-day,postoperative 2-day,one-month and 3-month mean liver SWV values were(2.34±0.36)m/s,(1.74±0.36)m/s,(1.62±0.30)m/s,and(1.56±0.28)m/s respectively.The differences in the mean liver SWV between its preoperative value and its postoperative 2-day,one-month and 3-month value were statistically significant(all P<0.05),and statistically significant difference in the mean liver SWV also existed between postoperative 2-day value and postoperative 3-month value(P<0.05).The mean HVPG decreased from preoperative(15.19±2.35)mmHg(1 mmHg=0.133 kPa)to postoperative(6.44±1.34)mmHg(P<0.05).The preoperative one-day liver SWV was positively correlated with preoperative HVPG(r=0.803,P<0.01).The postoperative 2-day liver SWV also carried a positive correlation with the postoperative HVPG(r=0.844,P<0.01).The difference value(D-value)between preoperative liver SWV value and postoperative 2-day liver SWV value was(0.59±0.27)m/s,and the D-value between preoperative HVPG value and postoperative HVPG value was(8.75±1.92)mmHg,and a positive correlation existed between the above two D-values(r=0.676,P<0.01).Conclusion There is a good correlation between liver SWV and HVPG,which can be used to evaluate the postoperative efficacy of BCS patients after receiving interventional therapy.(J Intervent Radiol,2023,32:1178-1183)
RESUMEN
Objective To discuss the clinical value of systemic immune-inflammation index(SII)in predicting the prognosis of patients with extrahepatic cholangiocarcinoma(ECCA)treated with biliary stenting combined with 125I seeds implantation.Methods A total of 128 patients with unresectable ECCA,who received biliary stenting combined with 125I seeds implantation at the Interventional Department of the Affiliated Hospital of Xuzhou Medical University of China between August 2018 and August 2021,were enrolled in this study.The peripheral blood routine testing was performed within 3 days before operation,based on which the SII was calculated.Receiver operating characteristic(ROC)curve was applied to determine the optimal cut-off value of SII,based on which the patients were divided into high-SII group and low-SII group.Cox regression model was used to analyze the independent factors affecting patient prognosis.The Kaplan-Meier curve was plotted to analyze the one-year survival.Results The optimal cut-off value of SII was 1 050,the sensitivity was 66.0%,the specificity was 69.3%,and the area under ROC curve of SII was 0.676.The one-year survival rate of patients with ECCA in the high-SII group was significantly lower than that in the low-SII group(P<0.05).Univariate Cox regression analysis indicated that vascular invasion,T stage,adjuvant chemotherapy,CA19-9,and preoperative SII were the important factors affecting the prognosis of patients with ECCA.Multivariate Cox regression analysis revealed that T stage,CA19-9,and preoperative SII were the independent risk factors for patient prognosis,while adjuvant chemotherapy was a protective factor.The Kaplan-Meier curves showed that the one-year survival rate in high-SII group was remarkably lower than that in the low-SII group.Conclusion Preoperative SII has an important value in evaluating the prognosis of patients with ECCA who are treated with biliary stenting combined with 125I seed implantation.(J Intervent Radiol,2023,32:1221-1225)

Objective:To study the risk factors of Budd-Chiari syndrome (BCS) associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.Methods:The data of 340 patients with BCS who underwent endovascular recanalization at the Affiliated Hospital of Xuzhou Medical University between January 2015 and June 2021 were retrospectively collected. Using propensity score matching, a total of 57 patients (40 males and 17 females) were enrolled into this study, with the age of (50.4±8.7) years. Patients were divided into the hepatocellular carcinoma group ( n=19) and the control group ( n=38) according to whether occurrence of hepatocellular carcinoma after cardovascular recanalization. Preoperative indicators including gender, age, BCS type, and model for end-stage liver disease (MELD) score, and postoperative indicators including alpha fetoprotein, intrahepatic nodule formation, vascular restenosis, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were compared between the two groups after propensity score matching. Multivariate logistic regression analysis was used to analyze the risk factors of BCS associated with after endovascular recanalization in these patients. Results:There were no significant differences in gender, age, BCS type, MELD score and other preoperative data between the two groups (all P>0.05). The proportions of patients with postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, ALT>50 U/L, intrahepatic nodules and vascular restenosis after endovascular treatment in the hepatocellular carcinoma group were significantly higher than those in the control group (all P<0.05). Multivariate analysis showed postoperative alpha fetoprotein >9.0 μg/L ( OR=46.778, 95% CI: 3.310-661.140), AST>40 U/L ( OR=36.307, 95% CI: 1.317-1 001.009), intrahepatic nodule formation ( OR=66.254, 95% CI: 4.225-1 038.974) and vascular restenosis ( OR=16.276, 95% CI: 1.712-154.773) to have an increased risk of being associated with hepatocellular carcinoma in these BCS patients (all P<0.05). Conclusion:Postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, intrahepatic nodule formation and vascular restenosis were independent risk factors of BCS associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.

ObjectiveTo investigate the effect and mechanism of total flavones of Spatholobi Caulis (TFSC) against depression in rats. MethodThe fifty KM mice were randomly divided into the normal group and high-, medium-, and low-dose (1, 0.5, 0.25 g·kg-1) TFSC groups and gavaged with the corresponding drugs for 12 successive days. One hour after the last administration, the immobility time in forced swimming test and tail suspension test was recorded. The SD rats were randomly divided into the normal group, model group, fluoxetine (5 mg·kg-1) group, and high- and low-dose (1, 0.25 g·kg-1) TFSC groups. Following the exposure of rats to two different kinds of stimuli daily for inducing chronic unpredictable stress, they were administered with the corresponding drugs for 21 d. After the experiment, the levels of serum neurotransmitters and inflammatory factors in rats were detected by enzyme-linked immunosorbent assay (ELISA). The changes in hippocampal neurons of rats were observed by hematoxylin-eosin (HE) and Nissl staining. The mRNA expression levels of nuclear factor-κB (NF-κB) and tumor necrosis factor-α (TNF-α) in the hippocampus of rats were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and the protein expression levels of cAMP-response element binding protein (CREB), phosphorylated CREB (p-CREB), and brain-derived neurotrophic factor (BDNF) in hippocampal tissues by Western blot. ResultCompared with the normal group, TFSC significantly shortened the immobility time of mice in tail suspension and swimming tests (P<0.05). Compared with the normal group, the model group exhibited reduced sucrose intake and wilderness activity (P<0.01), decreased 5-HT, DA, NE (P<0.05, P<0.01), MAO, IL-6, TNF-α (P<0.05, P<0.01), damaged neurons, increased mRNA levels of TNF-α and NF-κB (P<0.01), and down-regulated BDNF and CREB protein expression (P<0.05). Compared with the model group, TFSC significantly enhanced sucrose intake and wilderness activity of rats (P<0.05), increased the serum 5-HT, DA and NE (P<0.05, P<0.01), and decreased the serum MAO, IL-6, and TNF-α (P<0.05, P<0.01) as well as NF-κB and TNF-α mRNA expression (P<0.01), up-regulated the protein expression levels of BDNF and CREB (P<0.01), and improved the pathological symptoms of hippocampus. ConclusionTFSC improved the hippocampal neurons of rats via CREB/BDNF signaling pathway and reduced depressive pathological damage, thus relieving depression.
RESUMEN
Artemisia annua is the main natural source of artemisinin production. In A. annua, extended drought stress severely reduces its biomass and artemisinin production while short-term water-withholding or abscisic acid (ABA) treatment can increase artemisinin biosynthesis. ABA-responsive transcription factor AabZIP1 and JA signaling AaMYC2 have been shown in separate studies to promote artemisinin production by targeting several artemisinin biosynthesis genes. Here, we found AabZIP1 promote the expression of multiple artemisinin biosynthesis genes including AaDBR2 and AaALDH1, which AabZIP1 does not directly activate. Subsequently, it was found that AabZIP1 up-regulates AaMYC2 expression through direct binding to its promoter, and that AaMYC2 binds to the promoter of AaALDH1 to activate its transcription. In addition, AabZIP1 directly transactivates wax biosynthesis genes AaCER1 and AaCYP86A1. The biosynthesis of artemisinin and cuticular wax and the tolerance of drought stress were significantly increased by AabZIP1 overexpression, whereas they were significantly decreased in RNAi-AabZIP1 plants. Collectively, we have uncovered the AabZIP1-AaMYC2 transcriptional module as a point of cross-talk between ABA and JA signaling in artemisinin biosynthesis, which may have general implications. We have also identified AabZIP1 as a promising candidate gene for the development of A. annua plants with high artemisinin content and drought tolerance in metabolic engineering breeding.
RESUMEN
Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.
