Résumé
As a new strategy for the application of sacubitril/valsartan (LCZ696) in patients with CKD, much evidence showed that it improved the prognosis of patients with CKD. This review summarizes the efficacy and safety of sacubitril/valsartan in physiology, pathology, pharmacology and clinical application by searching Wanfang, CNKI, PubMed and other databases for related articles on the application of sacubitril/valsartan in CKD patients. Although LBQ657, the active product of sacubitril, has a high drug accumulation in patients with moderate, severe renal injury, and ESRD, it is not cleared in hemodialysis, and has very little eliminated in peritoneal dialysis, which does not affect its safety. Compared with angiotensin converting enzyme inhibitor and angiotensin receptor blocker drugs, LCZ696 could increase the blood pressure control rate, improve cardiac function, slow down the decline of glomerular filtration rate, and significantly improve cardiovascular outcomes without more adverse events. Sacubitril/valsartan can be used in all levels of CKD patients complicated with hypertension and/or heart failure, with reliable safety and tolerance.
Résumé
Lung cancer is the leading type of cancer death, and most patients with lung cancer are diagnosed at an advanced stage and have a very poor prognosis. Although low-dose computed tomography (LDCT) has entered the clinic as a screening tool for lung cancer, its false-positive rate is more than 90%. As one of the epigenetic modifications of research hotspots, DNA methylation plays a key role in a variety of diseases, including cancer.Hypermethylation of tumor suppressor genes and hypomethylation of proto-oncogenes are important events in tumorigenesis and development. Therefore, DNA methylation analysis can provide some useful information for the early screening, diagnosis, treatment and prognosis of lung cancer. Although invasive methods such as tissue biopsy remain the gold standard for tumor diagnosis and monitoring, they also have limitations such as inconvenience in sampling. In recent years, there has been a rapid development of liquid biopsy, which can detect primary or metastatic malignancies and reflect the heterogeneity of tumors. In addition, the blood sample can be collected in a minimally invasive or non-invasive format and is well tolerated in older and frail patients. This article explores some of the emerging technologies for DNA methylation analysis and provides an overview of the application of DNA methylation in the diagnosis and treatment of lung cancer.

【Objective】 To compare the clinical efficacy of high frequency holmium laser in the treatment of 2-3 cm renal calculi by minimally invasive percutaneous nephrolithotomy (mPCNL) and retrograde intrarenal surgery (RIRS). 【Methods】 The clinical data of 105 patients with a solitary 2-3 cm renal calculus treated during Oct. 2020 and Oct. 2022 were retrospectively analyzed. The patients were divided into two groups, including 52 cases in the RIRS group and 53 cases in the mPCNL group. The one-stage stone clearance rate, operation time, hemoglobin decline within 24 hours, inflammatory indicators within 24 hours after operation, postoperative complications, hospital stay and hospitalization costs were compared between the two groups. 【Results】 There were no significant differences in the preoperative general data, one-stage stone clearance rate, inflammatory indicators within 24 hours and incidence of postoperative complications between the two groups (P>0.05). The RIRS group had less decrease of hemoglobin than the mPCNL group [(6.35±2.00) g/L vs. (12.25±5.72) g/L, P=0.001], shorter hospital stay [(5.13±0.82) d vs. (7.92±1.59) d, P<0.001], lower hospitalization costs [(15 221.52±796.46) yuan vs. (19 514.51±909.98) yuan, P<0.001], but longer operation time [(58.17±7.67) min vs. (49.60±4.52) min, P<0.001]. 【Conclusion】 Both mPCNL and RIRS are safe and effective in the treatment of 2-3 cm renal calculi with 40-80 Hz holmium laser, and the one-stage stone clearance rate is similar. Although RIRS needed longer operation time than mPCNL, it has the advantages of less surgical trauma, faster postoperative recovery and shorter hospital stay, and is more prospective in the treatment of 2-3 cm renal calculi.

ObjectiveTo compare the effect of routine speech training and computer-assisted training on post-stroke dysarthria. MethodsFrom March, 2021 to April, 2023, 72 patients with post-stroke dysarthria in Beijing Bo'ai Hospital were randomly divided into control group (n = 36) and experimental group (n = 36). Both groups received routine rehabilitation, while the control group received routine speech training, and the experimental group received computer-assisted training, for four weeks. They were assessed with modified Frenchay Dysarthria Assessment (m-FDA) and Speech Intelligibility (SI) before and after intervention. ResultsEight cases in the control group and one case in the experimental group dropped down. The scores of m-FDA and SI improved in both groups after treatment (|Z| > 4.183, P < 0.001), and there was no significant difference between two groups (|Z| < 1.598, P > 0.05). Noninferiority of m-FDA was found between two groups (|t| > 3.656, P < 0.001). ConclusionComputer-assisted training could improve the speech function of patients with post-stroke dysarthria, similar to routine speech training.
Résumé
BACKGROUND:In recent years,the incidence of hyperuricemia caused by purine metabolism disorders has been increasing,which can induce inflammatory responses and lead to renal injury. OBJECTIVE:To explore the role and mechanism of solute carrier family 2 member 12(SLC2A12)in hyperuricemia-related renal injury. METHODS:Renal tubular cells(HK2 cells)were divided into five groups:HK2 group,HK2+uric acid group,HK2+uric acid+NC group,HK2+uric acid+siSLC2A12 group,and HK2+uric acid+siSLC2A12+MK-2206 group.HK2 cells were treated with uric acid and transfected with siRNA SLC2A12,followed by MK-2206 treatment to inhibit AKT expression.Cell proliferation was detected by CCK-8 assay.Apoptosis was detected by TUNEL assay.qRT-PCR and western blot assay were used to detect fibrogenic factors as well as activation of the AKT/FOXO3a pathway.The concentrations of inflammatory cytokines were measured by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:(1)Uric acid treatment inhibited cell proliferation and promoted cell apoptosis in the HK2+uric acid group compared with the HK2 group.The proliferative ability of cells in the HK2+uric acid+siSLC2A12 group was further decreased and apoptotic cells were further increased compared with the HK2 group.Compared with the HK2+uric acid+siSLC2A12 group,the HK2+uric acid+siSLC2A12+MK-2206 group showed an increase in cell proliferation and a decrease in apoptotic cells.(2)Compared with the HK2 group,the connective tissue growth factor(CTGF),α-smooth muscle actin(α-SMA)and transforming growth factor beta(TGF-β)expressions increased in the HK2+uric acid group;CTGF,α-SMA and TGF-β expression further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,the CTGF,α-SMA and TGF-β expressions decreased.(3)Compared with the HK2 group,the expression of p-AKT,FOXO3a,and p-FOXO3a elevated in the HK2+uric acid group;the expression of p-AKT further increased,while the expression of FOXO3a and p-FOXO3a decreased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,p-AKT expression decreased;FOXO3a and p-FOXO3a expression increased in the HK2+uric acid+siSLC2A12+MK-2206 group.(4)Compared with the HK2 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels increased in the HK2+uric acid group;interleukin-6,interleukin-1 β,and tumor necrosis factor α levels further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels diminished in the HK2+uric acid+siSLC2A12+MK-2206 group.(5)These findings indicate that SLC2A12 may protect against hyperuricemia-induced renal injury by counteracting uric acid-induced tubular fibrosis and inflammation through activation of the FOXO3a pathway.

Objective:To compare the repair effects of three kinds of treatment methods included synovial mesenchymal stem cells(SMSCs),platelet rich plasma(PRP)and the combination of them with knee joint cavity injection on cartilage injury of rabbit.Methods:A total of 24 New Zealand rabbits were selected to establish a cartilage injury model of knee joint by using surgery in knee joint of them.The rabbits with cartilage injury model were divided into four groups using a random number table method,which included blank group,single SMSCs with joint cavity injection group(SMSCs group),PRP with joint cavity injection group(PRP group)and the combination of SMSCs and PRP with joint cavity injection group(SMSCs+PRP group),with 6 rabbits in each group.The synovium of four groups of rabbits were scraped off their joints to conduct in vitro culture of SMSCs,as well as the morphological observation and identification of SMSCs.The venous bloods of rabbits were extracted to prepare PRP by centrifugation.The contents of PRP,platelet and growth factor in blood were compared.The SMSCs and PRP were injected into the knee joint cavity of three groups of rabbits with model.After 2,4 and 6 weeks of injection treatment,the repair statuses of cartilages at defection area of different groups were evaluated according to cartilage repair scoring table of International Association for Cartilage Repair(ICRS).Results:The primary synovial cells of rabbit knee joint synovium were initially round in shape after isolation,but almost all of them were spindle shaped after passage.The positive detection rates of SMSCs surface antigen CD73,CD90 and CD105 of 4 group were respectively 100%,99.22%and 99.99%.The CD45 detection was 0.5%,which indicated that they possessed the property of stem cell.The platelet count of 4 groups showed that the platelet concentration in PRP was approximate 6 times of that in whole blood.The concentrations of platelet derived growth factor(PDGF),transforming growth factor-β(TGF-β)and vascular endothelial growth factor(VEGF)were respectively(569.15±57.48)ng/mL,(633.56±63.90)ng/mL and(1 243.55±106.04)ng/mL in PRP,which were approximately 5 times,6 times and 7 times of that in whole blood,respectively.After 2 weeks of injection treatment for joint cavity,there was no significant statistical difference in the scores of cartilage repair among 4 groups(P>0.05).At 4 and 6 weeks of injection treatment,the morphological and histological score of cartilage repair of the SMSCs+PRP group were significantly higher than those of the blank group,and the differences were significant(t4 week=6.35,9.15,t6 week=8.16,8.60,P<0.05),respectively.Conclusion:The repair effect of SMSCs combined with PRP on cartilage injury of rabbit is significantly better than that of single PRP and single SMSCs,respectively,and all of them are better than those without treatment.SMSCs combined with PRP can significantly improve the effect of self-repair of cartilage injury.
Résumé
Chronic obstructive pulmonary disease (COPD) is characterized by excess in nature and deficiency in superficiality. For COPD patients, the deficiency of lung and kidney is the basis for production of the latent toxin, and repeated exogenous infection is the main factor for the latent toxin to enter the lung. The key pathogenesis of stable COPD is the entry of latent toxin into the lung and the injury of lung and collaterals. Therefore, tonifying lung and kidney, removing toxins and dredging collaterals are the core treatment methods for COPD in stable period. Bufei Decoction is with good efficacy in the treatment of COPD in stable period, which can not only tonify lung and kidney to consolidate, but also dredging collaterals to remove toxins. Based on the pathogenesis of "latent toxin entering lung", the relevant mechanisms of Bufei Decoction in treating stable COPD were further understood and explored, in order to benefit clinical practice.

This study aims to evaluate the quality consistency of Saposhnikoviae Radix based on carbohydrates, and explore the potential of carbohydrates as the internal quality control indicators of Saposhnikoviae Radix. The total polysaccharides were quantified by UV-Vis spectrophotometry and the molecular weight range of the polysaccharides was determined by high performance gel-permeation chromatography-evaporative light scattering detection(HPGPC-ELSD). The monosaccharides in polysaccharides and the free monosaccharides were quantified by high performance liquid chromatography-UV detection(HPLC-UV), and the oligosaccharides and fructose were quantified by high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD). The carbohydrate-based quality of Saposhnikoviae Radix was compared among 45 batches of commercial samples and 13 batches of self-collected samples. The results showed that the molecular weight distribution, monosaccharide composition, oligosaccharide, and free monosaccharide composition were similar in the 58 batches of samples. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in commercial samples were 39.66, 148.79, and 68.62 mg·g~(-1), respectively. The content showed significant differences among batches, with the highest differences of 3.51, 1.75, and 2.58 times, respectively. The RSD of the relative ratios of monosaccharides in the polysaccharides in commercial samples reached 28%-45%. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in self-collected samples were 68.07, 145.76, and 42.04 mg·g~(-1), respectively, with the inter-region differences of 2.88, 1.88, and 1.07 times, respectively. The RSD of the relative ratios of monosaccharides in polysaccharides in self-collected samples ranged from 8.2% to 59%. The total polysaccharides and total free monosaccharides in self-collected samples were 1.72 times higher and 1.63 times lower, respectively, than those in commercial samples. The content of oligosaccharides was similar between self-collected samples and commercial samples. To sum up, carbohydrates are one of the material bases for the internal quality consistency of Saposhnikoviae Radix. The qualitative characteristics of polysaccharides and the quantitative characteristics of polysaccharides and oligosaccharides are related to the origin of medicinal materials. Moreover, the quantitative characteristics of polysaccharides and free monosaccharides may be related to the storage conditions. Carbohydrates are potential indicators for the quality control of Saposhnikoviae Radix and deserve attention.

Objective: To evaluate the efficacy and safety of HLA-haploidentical hematopoietic stem cell transplantation (allo-HSCT) for hepatitis-related aplastic anemia (HRAA) patients. Methods: Retrospective analysis was performed on hepatitis-associated aplastic anemia patients who received haplo-HSCT at our center between January 2012 and June 2022. October 30, 2022 was the final date of follow-up. Results: This study included 28 HRAA patients receiving allo-HSCT, including 18 males (64.3% ) and 10 females (35.7% ), with a median age of 25.5 (9-44) years. About 17 cases of severe aplastic anemia (SAA), 10 cases of very severe aplastic anemia (VSAA), and 1 case of transfusion-dependent aplastic anemia (TD-NSAA) were identified. Among 28 patients, 15 patients received haplo-HSCT, and 13 received MSD-HSCT. The 2-year overall survival (OS) rate, the 2-year failure-free survival (FFS) rate, the 2-year transplant-related mortality (TRM) rate, the 100-day grade Ⅱ-Ⅳ acute graft-versus-host disease (aGVHD) cumulative incidence rate, and the 2-year chronic graft-versus-host disease (cGVHD) cumulative incidence rate were 81.4%, 81.4% (95% CI 10.5% -20.6% ), 14.6% (95% CI 5.7% -34.3% ), 25.0% (95% CI 12.8% -45.4% ), and 4.2% (95% CI 0.6% -25.4% ), respectively. After transplantation, all patients had no significant liver function damage. Compared with the MSD-HSCT group, only the incidence of cytomegaloviremia was significantly higher in the haplo-HSCT group [60.0% (95% CI 35.2% -84.8% ) vs 7.7% (95% CI 0-22.2% ), P=0.004]. No statistically significant difference in the Epstein-Barr virus was found in the 2-year OS, 2-year FFS, 2-year TRM, and 100-day grade Ⅱ-Ⅳ aGVHD cumulative incidence rates and 2-year cGVHD cumulative incidence rate. Conclusion: Allo-HSCT is safe and effective for HRAA, and haplo-HSCT can be used as a safe and effective alternative for newly diagnosed HRAA patients who cannot obtain HLA-matched sibling donors.

The study aims to explore the active molecules of traditional Chinese medicine that specifically bind to interleukin-15 receptor α (IL-15Rα) using molecular docking and surface plasmon resonance (SPR) technology. AutoDock molecular docking software was used to perform simulated docking of more than 3 000 compounds from 48 traditional Chinese medicines at IL-15Rα and screen the specific binding compounds. Then Biocore T200 biomolecular interaction analysis system of SPR was used to confirm the binding specificity of the selected target compounds. Finally, the biological effects of the target compounds on IL-15Rα were verified by cell biological experiments. The results showed that neoprzewaquinone A (Neo) possessed the highest specific binding affinity among the active molecules from traditional Chinese medicine, and the dissociation constant (KD) value was (0.62 ± 0.20) µmol/L. The results of cell experiment showed that Neo significantly inhibited the proliferation of Mo7e cells induced by IL-15, and the IC50 was 1.075 µmol/L, approximately 1/120 of the IC50 of Cefazolin (IL-15 specific antagonist). These results suggest that Neo is a specific inhibitor of IL-15Rα and may be a potential active drug for the treatment of diseases related to the dysfunction of the IL-15Rα signaling.

OBJECTIVE@#A core genome multilocus sequence typing (cgMLST) scheme to genotype and identify potential risk clonal groups (CGs) in Proteus mirabilis.@*METHODS@#In this work, we propose a publicly available cgMLST scheme for P. mirabilis using chewBBACA. In total 72 complete P. mirabilis genomes, representing the diversity of this species, were used to set up a cgMLST scheme targeting 1,842 genes, 635 unfinished (contig, chromosome, and scaffold) genomes were used for its validation.@*RESULTS@#We identified a total of 205 CGs from 695 P. mirabilis strains with regional distribution characteristics. Of these, 159 unique CGs were distributed in 16 countries. CG20 and CG3 carried large numbers of shared and unique antibiotic resistance genes. Nine virulence genes ( papC, papD, papE, papF, papG, papH, papI, papJ, and papK) related to the P fimbrial operon that cause severe urinary tract infections were only found in CG20. These CGs require attention due to potential risks.@*CONCLUSION@#This research innovatively performs high-resolution molecular typing of P. mirabilis using whole-genome sequencing technology combined with a bioinformatics pipeline (chewBBACA). We found that the CGs of P. mirabilis showed regional distribution differences. We expect that our research will contribute to the establishment of cgMLST for P. mirabilis.

This study aimed to demonstrate the effect of Banxia Baizhu Tianma Decoction(BBTD) on realizing withdrawal of anti-epileptic drugs and explore the relationship between BBTD and the amino acid metabolism by transcriptomic analysis in the rat model of epilepsy induced by lithium chloride-pilocarpine. The rats with epilepsy were divided into a control group(Ctrl), an epilepsy group(Ep), a BBTD & antiepileptic drug integrative group(BADIG), and an antiepileptic drug withdrawal group(ADWG). The Ctrl and Ep were given ultrapure water by gavage for 12 weeks. The BADIG was given BBTD extract and carbamazepine solution by gavage for 12 weeks. The ADWG was given carbamazepine solution and BBTD extract by gavage for the former 6 weeks, and then only given BBTD extract for the latter 6 weeks. The therapeutic effect was evaluated by behavioral observation, electroencephalogram(EEG), and hippocampal neuronal morphological changes. High-throughput sequencing was used to obtain amino acid metabolism-related differen-tial genes in the hippocampus, and the mRNA expression in the hippocampus of each group was verified by real-time quantitative polymerase chain reaction(RT-qPCR). The hub genes were screened out through protein-protein interaction(PPI) network, and Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed. Two ceRNA networks, namely circRNA-miRNA-mRNA and lncRNA-miRNA-mRNA, were constructed for ADWG vs BADIG. The experimental results showed that compared with those in Ep, rats in ADWG were significantly improved in the behavioral observation, EEG, and hippocampal neuronal impairment. Thirty-four amino acid metabolism-related differential genes were obtained by transcriptomic analysis, and the sequencing results were confirmed by RT-qPCR. Eight hub genes were obtained through PPI network, involving several biological processes, molecular functions, and signal pathways related to amino acid metabolism. Finally, the circRNA-miRNA-mRNA ternary transcription network of 17 circRNA, 5 miRNA, and 2 mRNA, and a lncRNA-miRNA-mRNA ternary network of 10 lncRNA, 5 miRNA, and 2 mRNA were constructed in ADWG vs BADIG. In conclusion, BBTD can effectively achieve the withdrawal of antiepileptic drugs, which may be related to the transcriptomic regulation of amino acid metabolism.

Rheumatoid arthritis(RA) is an autoimmune disease that seriously affects the physical and mental health of patients, but its pathogenesis is still unclear. At present, clinical treatment drugs include conventional synthetic disease modifing anti-rheumatic drugs(csDMARDs), nonsteroid anti-inflammtory drugs(NSAIDs), hormones, small molecule targeted drugs, biological agents, etc. These drugs can relieve the clinical symptoms of most patients with RA to a certain extent, but there are still many limitations, such as drug adverse reactions and individual differences in drug efficacy. Therefore, the research on drug treatment targets and the development of low-toxicity drugs helps further improve the precise prevention, diagnosis, and treatment of RA. There is an urgent need for efficient and low-toxic treatments to delay the clinical progress of RA. As a treasure of Chinese culture, traditional Chinese medicine(TCM) is widely used as an alternative therapy in the treatment of various diseases, and has a significant clinical efficacy. TCM therapy(including monomer traditional Chinese medicine, classical compounds, and non-drug therapies) has a significant curative effect on RA. Based on the literature research in recent years, this paper reviewed the clinical and mechanism research of TCM therapy in the treatment of RA, and provided more in-depth thinking for the wide application of TCM therapy in clinical practice.

OBJECTIVE@#To study the application of different puncture techniques to inject bone cement in osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The clinical data of 282 patients with OVCFs treated from January 2017 to December 2019 were collected for a retrospective study. According to the surgical plan the patients were divided into group A and B, with 141 cases in each group. In group A, extreme lateral puncture was used to inject bone cement through unilateral puncture and bilateral puncture. In group B, bone cement was injected through unilateral pedicle puncture through pedicle approach. The operation status(operation time, radiation exposure time, bone cement injection volume, hospital stay) and complications were observed between two groups. Before operation and 6, 12 months after operation, the pain mediators such as serotonin 5-hydroxytryptamine (5-HT), prostaglandin E2(PGE2), substance P(SP) were compared, bone mineral density, anatomical parameters of the injured vertebrae (height of the anterior edge of the vertebral body, height of the posterior edge of the vertebral body, Cobb angle), visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated between two groups.@*RESULTS@#There were no significant difference in operation time, radiation exposure time, hospital stay between two groups (P>0.05). The amount of bone cement injected in group A was greater than that in group B (P<0.05). The serum 5-HT, SP and PGE2 levels of group A were lower than those of group B at 12 months after operation (P<0.05). The height of anterior edge and height of the posterior edge of vertebral body in group A were greater than those of group B at 12 months after operation, Cobb angle of group A was smaller than that of group B, VAS and ODI were lower than those of group B(P<0.05). There was no significant difference in bone mineral density between two groups at 6 and 12 months postoperatively(P<0.05). There was no significant difference between two groups in postoperative complications (P>0.05).@*CONCLUSION@#Compared with unilateral puncture of the pedicle approach, unilateral puncture and bilateral cement injection technique is more conducive to the recovery of the injured vertebral anatomy and function, and do not prolong operation time, radiation exposure time, hospital stay, nor do increase the risk of nerve damage and bone cement leakage, and postoperative bone metabolism and bone mineral density are improved well, which is a safe and reliable surgical method for the treatment of OVCFs.

Objective: To investigate the early effect and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with a 10-day decitabine-containing conditioning regimen in the treatment of acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) . Methods: From April 2021 to May 2022, 31 AML/MDS patients who received allo-HSCT with a 10-day decitabine-containing conditioning regimen were analyzed. Results: AML (n=10), MDS-AML (n=6), CMML-AML (n=1), and MDS (n=14) were identified in 31 patients, 16 males, and 15 females, with a median age of 41 (20-55) yr. Neutrophils and platelets were successfully implanted in 31 patients (100%), with a median implantation duration of 12 (9-30) and 14 (9-42) days, respectively. During the preconditioning period, 16 patients (51.6%) developed oral mucositis, with 15 cases of Ⅰ/Ⅱ grade (48.4%) and one case of Ⅲ grade (3.2%). After transplantation, 13 patients (41.9%) developed CMV viremia, six patients (19.4%) developed hemorrhagic cystitis, and four patients (12.9%) developed a local infection. The median time of acute graft versus host disease (aGVHD) following transplantation was 33 (12-111) days. The cumulative incidence of aGVHD and Ⅲ/Ⅳ grade aGVHD was 41.9% (95% CI 26.9%-61.0%) and 22.9% (95% CI 13.5%-47.5%), respectively. There was no severe cGVHD, and mild and moderate chronic GVHD (cGVHD) incidence was 23.5% (95% CI 12.1%-43.6%). As of November 30, 2022, only one of the 31 patients had relapsed, with a 1-yr cumulative relapse rate (CIR) of 3.2% (95% CI 0.5%-20.7%). There was only one relapse patient death and no non-relapse deaths. The 1-yr overall survival (OS) and disease-free survival (DFS) rates were 92.9% (95% CI 80.3%-100%) and 96.8% (95% CI 90.8%-100%), respectively. Conclusions: A 10-day decitabine-containing conditioning regimen for allo-HSCT reduced relapse and was safe and feasible in treating AML/MDS.

Objective To investigate how the neutrophil extracellular traps (NETs) affect the proliferation and migration of mouse MC38 colorectal cancer cells and its mechanism. Methods Spleen neutrophils were extracted in mouse, followed by collection of NETs after ionomycin stimulation in vitro. The proliferation of MC38 cell was detected by CCK-8 assay, and migration ability were detected by TranswellTM and cell scratch assay, after co-incubation with MC38 cells. The mRNA expression of cellular matrix metalloproteinase 2 (MMP2) and MMP9 were detected by real-time fluorescence quantitative PCR, and the expression of MMP2, MMP9 and focal adhesion kinase (FAK), phosphorylated FAK protein were detected by Western blot. After silencing MMP9 using small interfering RNA (siRNA), the effect of NETs on the proliferation and migration ability of MC38 cells and the altered expression of related molecules were examined by previous approach. Results NETs promoted the proliferation and migration of MC38 cells and up-regulated the MMP9 expression and FAK phosphorylation. Silencing MMP9 inhibited the promotion of MC38 proliferation and migration by NETs and suppressed FAK phosphorylation. Conclusion NETs up-regulates MMP9 expression in MC38 cells, activates FAK signaling pathway and promotes tumor cell proliferation and migration.

Chang-Kang-Fang (CKF) formula, a Traditional Chinese Medicine (TCM) prescription, has been widely used for the treatment of irritable bowel syndrome (IBS). However, its potential material basis and underlying mechanism remain elusive. Therefore, this study employed an integrated approach that combined ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) with network pharmacology to systematically characterize the phytochemical components and metabolites of CKF, as well as elucidating its underlying mechanism. Through this comprehensive analysis, a total of 150 components were identified or tentatively characterized within the CKF formula. Notably, six N-acetyldopamine oligomers from CicadaePeriostracum and eight resin glycosides from Cuscutae Semen were characterized in this formula for the first time. Meanwhile, 149 xenobiotics (58 prototypes and 91 metabolites) were detected in plasma, urine, feces, brain, and intestinal contents, and the in vivo metabolic pathways of resin glycosides were elaborated for the first time. Furthermore, network pharmacology and molecular docking analyses revealed that alkaloids, flavonoids, chromones, monoterpenes, N-acetyldopamine dimers, p-hydroxycinnamic acid, and Cus-3/isomer might be responsible for the beneficial effects of CKF in treating IBS, and CASP8, MARK14, PIK3C, PIK3R1, TLR4, and TNF may be its potential targets. These discoveries offer a comprehensive understanding of the potential material basis and clarify the underlying mechanism of the CKF formula in treating IBS, facilitating the broader application of CKF in the field of medicine.

Objective To analyze the onset characteristics of type 2 diabetes mellitus (T2DM) with cognitive impairment in Baotou area, and study the improvement effect of GLP-1 receptor agonists. Methods A total of 320 patients with T2DM admitted between September 2021 and September 2022 were selected and divided into the observation group with T2DM and cognitive dysfunction and the negative control group without cognitive dysfunction according to their cognitive function status , Among the 160 cases in each group; Patients with type 2 diabetes and cognitive impairment were randomly divided into a treatment group and a control group, 80 cases in each group; the control group was treated with conventional treatment, and the treatment group was additionally treated with semaglutide; Logistics multiple regression model was used to analyze T2DM The related risk factors of cognitive impairment in patients were assessed by the Mini-Mental State Examination (MMSE) score to evaluate the cognitive function of the patients. Results Multivariate regression model showed that course of disease, age, vitamin D, HbA1c, LDL-C, BMI, Hcy, Lp-PLA2, TNF-α, IL-6 and folic acid levels were also independent risk factors for cognitive impairment in T2DM patients (P<0.05); There was a significant positive correlation between GLP-1 receptor agonists and cognitive function recovery in T2DM patients with cognitive impairment (P<0.05). Conclusion The onset of T2DM with cognitive impairment in Baotou area is often accompanied by a long course of disease, older age, abnormal levels of vitamin D, HbA1c, LDL-C, BMI, Hcy, Lp-PLA2, TNF-α, IL-6 and folic acid, and GLP -1 receptor agonists have a clear role in improving the cognitive function of patients.
