Objective To investigate microRNA(miRNA)expression profiles in peripheral blood and skin lesions of patients with psoriasis vulgaris(PV), and to seek miRNAs consistently expressed in peripheral blood and skin lesions. Methods A miRNA microarray was used to screen differentially expressed miRNAs in skin lesions and peripheral blood samples between 17 patients with PV and 4 healthy human controls, and real?time fluorescence?based quantitative PCR(RT?qPCR)to verify the differentially expressed miRNAs. The correlations of these differentially expressed miRNAs with psoriasis area and severity index(PASI)score were assessed by Pearson correlation analysis. Results The Agilent human miRNA microarray profiling revealed 15 miRNAs consistently expressed in skin lesions and peripheral blood of patients with PV. Of the 15 miRNAs, 7 were verified as consistently expressed miRNAs by RT?qPCR. Among the 7 miRNAs, the expression intensity of miR?30e?5p, miR?192?5p, miR?17?3p and miR?1227?5p was negatively correlated with PASI scores(all P<0.05), while that of miR?125b?5p, miR?642a?5p and miR?29a?5p was uncorrelated with PASI scores(all P>0.05). Conclusion Some miRNAs are consistently expressed in skin lesions and plasma of PV patients, which are expected to serve as biomarkers for evaluation of psoriasis severity.

Objective:To explore the regulatory effect of miR-873-5p micro-RNA targeting voltage-dependent anion channel protein 1 (VDAC1) in neurons and its mechanism.Methods:Murine nerve cells were randomly divided in vitro into a control group, a model group, a mimetic negative carrier (miR-con) group and an miR-873-5p group. The epileptiform hippocampal nerve cell model was induced in all of the cells except those in the control group using magnesium-free medium. The control group was normally cultured, while the miR-con and miR-873-5p groups were transfected with miR control and miR-873-5p RNA respectively. Real-time fluorescent quantitative polymerase chain reactions were used to detect the expression of miR-873-5p and VDAC1 mRNA. Western blotting was employed to detect VDAC1, B-cell lymphoma/leukemia-2 protein (Bcl-2), Bcl-2 associated X protein (Bax) and cleared caspase-3 in the neurons. The levels of reactive oxygen species (ROS), malondialdehyde (MDA) and glutathione (GSH) were measured using the DCFH-DA fluorescent probe, the thiobarbituric acid method and enzyme-linked immunosorbent assay respectively. Any apoptosis was detected using flow cytometry, while the targeting of miR-873-5p on VDAC1 was verified using the double fluorescence zymase reporter gene method.Results:Compared with the control group, a significant decrease in the average expression of miR-873-5p, Bcl-2 and in GSH and MDA levels was observed in the model group, but there was a significant increase in the average level of VDAC1, Bax, cleaved caspase-3 and ROS and in the rate of apoptosis. Compared with the miR-con group, a significant decrease in the average expression of Bax, cleaved caspase-3, ROS and in the apoptosis rate was observed in the miR-873-5p group, but there was a significant increase in the average level of Bcl-2, GSH and MDA. Moreover, it was verified that miR-873-5p reduced the expression of VDAC1.Conclusion:miR-873-5p protects damaged neurons by inhibiting their apoptosis through negatively regulating the target gene VDAC1 and the oxidative stress response.

Objective To evaluate the genetic toxicity of Wentilactone A. Methods The classical genotoxicity test combination (Ames test, in vitro CHO cell chromosome aberration test and mouse bone marrow micronucleus test) was used to detect the genotoxicity of Wentilactone A. Results Ames test suggested that Wentilactone A was not mutagenic against Salmonella typhimurium with or without the metabolic activation system (S9) at five doses of 5 000, 500, 50, 5, and 0.5 μg/dish. CHO cell chromosome aberration test suggested that the CHO cells cultured in 4 h and 24 h did not induce chromosomal aberrations in three dose groups at the final concentration of 23.74, 47.48, 94.96 μg/ml, with and without S9. The mouse bone marrow micronucleus test showed no significant difference in the bone marrow micronucleus induction rate of cells at three doses of 100, 200, and 400 mg/kg treated for 24 h and at dose of 400 mg/kg treated for 48 h compared with the solvent control group (P>0.05). Conclusion These results indicated that Wentilactone A did not exhibit genetic toxicity based on the Ames test, CHO chromosomal aberration test and micronucleus assay. It was suggested that Wentilactone A had no genetic toxicity and potential carcinogenicity.

Objective:To evaluate the efficacy and safety of endoscopic biliary drainage for biliary fistula.Methods:Data of consecutive 409 biliary fistula patients who were treated and diagnosed at the First Medical Center of Chinese PLA General Hospital from November 2002 to November 2022 were reviewed, and 53 patients who received endoscopic retrograde cholangiopancreatography (ERCP) drainage were finally included. General information, procedural conditions, clinical outcomes and adverse events were analyzed. The patients were categorized into two groups: the endoscopic retrograde biliary drainage (ERBD) group ( n=46) and the endoscopic nasobiliary drainage (ENBD) group ( n=7). Procedural characteristics, operation outcomes, and operation time were compared between the two groups. Results:There were 36 males and 17 females, with the age of 52.2±12.7 years, among whom 58.5% (31/53) were secondary to cholecystectomy. Clinical success was achieved in 83.0% (44/53) patients, with the operation time of 27.0 (13.5, 33.5) minutes and the treatment session of 1 (1, 2). The time to resolution was 89 (47, 161) days. The success rate of ERCP for low-grade biliary fistula was higher compared with that of high-grade biliary fistula [96.4% (27/28) VS 68.0% (17/25), χ2=7.57, P=0.006]. Bridging drainage achieved higher success rate compared with that of non-bridging drainage [91.7% (33/36) VS 64.7% (11/17), χ2=5.95, P=0.015], while different diameters of stents (≥10 Fr VS <10 Fr) achieved similar success rate [81.8% (27/33) VS 84.6% (11/13), χ2=0.05, P=0.822]. Adverse events occurred in 10 patients (18.9%), including 6 pancreatitis, 2 bleeding, 1 cholangitis and 1 death. Except for 1 death, 9 other adverse events were mild and managed with conservative treatment without interventions. There was no significant difference in clinical success rate [6/7 VS 82.6% (38/46), χ2=0.04, P=0.838] or the median operation time [28.0 min VS 23.0 min, Z=0.38, P=0.774] between ENBD group and ERBD group. Conclusion:Endoscopic biliary drainage is safe and effective for biliary fistula. ENBD and ERBD have comparable clinical efficacy. ERCP for low-grade biliary fistula may achieve a higher success rate, and bridging drainage may facilitate fistula resolution.

This retrospective analysis aimed to investigate the mutation profile of 16 common mutated genes in de novo acute myeloid leukemia (AML) patients. A total of 259 patients who were diagnosed of de novo AML were enrolled in this study. Mutation profiling of 16 candidate genes were performed in bone marrow samples by using Sanger sequencing.We identified at least 1 mutation in 199 of the 259 samples (76.8%), and 2 or more mutations in 31.7% of samples. FLT3-ITD was the most common mutated gene (16.2%, 42/259), followed by CEBPA (15.1%, 39/259), NRAS (14.7%, 38/259), and NPM1 (13.5%, 35/259). Concurrence was observed in 97.1% of the NPM1 mutated cases and in 29.6% of the double mutated CEBPA cases. Distinct patterns of co-occurrence were observed for different hotspot mutations within the IDH2 gene: R140 mutations were associated with NPM1 and/or FLT3-ITD mutations, whereas R172 mutations co-occurred with DNMT3A mutations only. Concurrence was also observed in 86.6% of epigenetic regulation genes, most of which co-occurred with NPM1 mutations. The results showed certain rules in the mutation profiling and concurrence of AML patients, which was related to the function classification of genes. Defining the mutation spectrum and mutation pattern of AML will contribute to the comprehensive assessment of patients and identification of new therapeutic targets.

ObjectiveThe differential expression of microRNAs （miRNAs） between the active stage and the remission stage of ulcerative colitis （UC） was analyzed by bioinformatics method， and the regulatory relationship was constructed by screening the differentially expressed genes （DEGs）. The mechanism of Xizhuo Jiedu recipe in the treatment of UC was speculated and verified by animal experiments. MethodThe miRNAs data set of colonic mucosa tissue of UC patients was obtained from the gene expression database （GEO）， and the most differentially expressed miRNAs were screened by GEO2R， Excel， and other tools as research objects. TargetScan， miRTarbase， miRDB， STRING， TRRUST， and Matescape databases were used to screen key DEGs， predict downstream transcription factors （TFs）， gene ontology （GO）， and conduct Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis. The key signaling pathways were selected for animal experiments. In animal experiments， the UC mouse model was prepared by making the mouse freely drink 2.5% dextran sodium sulfate （DSS）. Xiezhu Jiedu recipe and mesalazine were given by gavage for seven days， and the inflammatory infiltration of colonic mucosa was observed by hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of miR-155-5p in colon tissue. Immunohistochemistry and Western blot were used to detect the protein expression levels of cytokine signal transduction inhibitor （SOCS1）， phosphorylated transcriptional signal transductor and activator 3 （p-STAT3）， phosphorylated Janus kinase 2 （p-JAK2）， and retinoic acid-associated orphan receptor-γt （ROR-γt）. The expression levels of transforming growth factor-β （TGF-β）， interleukin-17 （IL-17）， interleukin-6 （IL-6）， and interleukin-10 （IL-10） in serum were detected by enzyme linked immunosorbent assay （ELISA）. ResultThe GSE48957 dataset was screened from the GEO database， and miR-155-5p was selected as the research object from the samples in the active and remission stages. 131 DEGs were screened. The GO/KEGG enrichment analysis was closely related to biological processes such as positive regulation of miRNA transcription and protein phosphorylation， as well as signaling pathways such as stem cell signaling pathway， IL-17 signaling pathway， and helper T cell 17 （Th17） cell differentiation. The Matescape database was used to screen out 10 key DEGs， among which SOCS1 was one of the key DEGs of miR-155-5p. Further screening of the TFS of key DEGs revealed that STAT3 was one of the main TFs of SOCS1. The results of animal experiments showed that Xiezhu Jiedu Recipe could effectively down-regulate the mRNA expression of miR-155-5p and protein expression of p-STAT3， p-JAK2， and ROR-γt in colon tissue of UC mice and the expression of IL-17 and IL-6 in serum of UC mice， up-regulate the protein expression of SOCS1 and the expression of TGF-β and IL-10， increase the level of anti-inflammatory factors， and reduce inflammatory cell infiltration. ConclusionIt is speculated that Xizhuo Jiedu recipe may interfere with SOCS1 by regulating the expression of miR-155-5p in UC mice， inhibit the phosphorylation of STAT3， inhibit the differentiation of CD4⁺ T cells into Th17 cells， reduce the levels of pro-inflammatory factors （IL-17 and IL-6）， and increase the levels of anti-inflammatory factors （TGF-β and IL-10）. As a result， the inflammation of colon mucosa in UC mice was alleviated.
