Objective:To discuss the effect of long non-coding RNA(lncRNA)DUXAP8 in exosomes(Exo)derived from the lung cancer A549 cells on the growth and immune escape of the lung cancer cells,and to clarify the mechanism.Methods:The human lung cancer cell line A549 was cultured,and its exosomes were extracted and identified.The A549 cells were treated with PKH67-labeled Exo to observe the uptake of Exo by A549 cells.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression level of lncRNA DUXAP8 in A549 cells before and after Exo treatment.The A549 cells were divided into control group(no treatment),Exo group(A549 cells treated with Exo),Exo+sh-NC group(A549 cells treated with Exo and then transfected with sh-NC),and Exo+sh-DUXAP8 group(A549 cells treated with Exo and then transfected with sh-DUXAP8).RT-qPCR method was used to detect the expression level of lncRNA DUXAP8 in A549 cells in various groups;colony formation assay was used to detect the colony formation abilities of the A549 cells in various groups;5-ethynyl-2'-deoxyuridine(EdU)staining method was used to detect the proliferation abilities of the A549 cells in various groups.After co-culturing A549 cells in various groups with human peripheral blood lymphocytes,flow cytometry was used to detect the percentages of activated CD8+T lymphocytes in the human peripheral blood lymphocytes in various groups;3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)method was used to detect the killing rates of human peripheral blood lymphocytes on the A549 cells in various groups.Results:The diameter of Exo vesicles was 50-150 nm,and the exosome-specific marker proteins cluster of differentiation 63(CD63),cluster of differentiation 9(CD9),tumor susceptibility gene 101(TSG101),and heat shock protein 70(HSP70)were positively expressed,indicating successful exosome extraction.A549 cells efficiently took up PKH67-labeled Exo.The RT-PCR results showed that compared with A549 cells cultured alone,the expression level of lncRNA DUXAP8 in the A549 cells was increased after treatment with Exo derived from A549 cells(P<0.05).compared with control group,the expression level of lncRNA DUXAP8 in the A549 cells in Exo group was increased(P<0.05);compared with Exo group,the expression level of lncRNA DUXAP8 in the A549 cells in Exo+sh-DUXAP8 group was decreased(P<0.05),while there were no significant difference in the expression level of IncRNA DUXAP8 in the cells in Exo+sh-NC group(P>0.05).The colony formation assay results showed that compared with control group,the number of colony formation of the A549 cells in Exo group was increased(P<0.05);compared with Exo group,the number of colony formation of the A549 cells in Exo+sh-DUXAP8 group was decreased(P<0.05),while there was no significant difference in the number of colony formation of the A549 cells in Exo+sh-NC group(P>0.05).The EdU staining results showed that compared with control group,the EdU-positive rate of the A549 cells in Exo group was increased(P<0.05);compared with Exo group,the EdU-positive rate in A549 cells in Exo+sh-DUXAP8 group was decreased(P<0.05),while there was no significant difference in the EDU-positive rate in the cells in Exo+sh-NC group(P>0.05).The flow cytometry results showed that compared with control group,the percentage of activated CD8+T lymphocytes in the human peripheral blood lymphocytes in Exo group was decreased(P<0.05);compared with Exo group,the percentage of activated CD8+T lymphocytes in the human peripheral blood lymphocytes in Exo+sh-DUXAP8 group was increased(P<0.05),while there was no significant difference in the percentage of activated CD8+T lymphaytes in Exo+sh-NC group(P>0.05).The MTT assay results showed that compared with control group,the killing rate of human peripheral blood lymphocytes on the A549 cells in Exo group was decreased(P<0.05);compared with Exo group,the killing rate of human peripheral blood lymphocytes on A549 cells in Exo+sh-DUXAP8 group was increased(P<0.05),while no significant difference was observed in Exo+sh-NC group(P>0.05).Conclusion:The lncRNA DUXAP8 in exosomes derived from the lung cancer A549 cells promotes the proliferation of lung cancer cells and tumor immune escape.

Objective:To observe the incidence of early blood eosinophils (Eos) elevation in patients with peritoneal dialysis (PD), analyze its related factors, and its relationship with early-onset peritonitis in PD patients.Methods:This study was a retrospective observational cohort study. Patients who underwent PD catheterization in Peking University People's Hospital from January 2012 to December 2022 were included. After surgery, PD treatment was started immediately and followed up regularly ≥12 months. The general information and laboratory indexes collected 1 week before catheterization, and at 1, 3, 6 and 12 months after catheterization were recorded. The occurrence of elevated blood Eos (≥0.5×10 9/L) during the early stage of PD, the related factors of Eos elevation (≥0.5×10 9/L) and the relationship with early-onset peritonitis (within 12 months after PD initiation) were analyzed. Results:(1) A total of 235 patients were enrolled, with an age of (57.9.±13.9) years, including 136 males (57.9%). The primary diseases were predominantly chronic glomerulonephritis (111/235, 42.7%) and diabetic nephropathy (83/235, 35.3%). During the 12-month follow-up period, 73 patients had elevated blood Eos (31.1%), of which 37 cases (50.7%) occurred within 1 month after PD catheterization, 21 cases (28.7%) occurred 2-3 months after PD catheterization, 12 cases (16.4%) occurred 4-6 months after PD catheterization, and 3 cases (4.1%) occurred 7-12 months after PD catheterization. In 73 patients with elevated Eos, 69 cases (94.5%) were mildly elevated, 4 cases (5.5%) were moderately elevated. As for the duration of elevated blood Eos, 28 cases (38.4%) lasted less than 1 month, 27 cases (37.0%) lasted 1-3 months, and 18 cases (24.7%) lasted more than 3 months. (2) In patients with elevated blood Eos, the proportion of male patients (71.4% vs. 52.1%, χ 2=7.515, P=0.006), the proportion of diabetes mellitus (55.7% vs. 41.2%, χ 2=4.168, P=0.046), and the proportion of combined vascular disease (32.9% vs. 18.2%, χ 2=6.060, P=0.017) were significantly higher than those patients in normal blood Eos group. (3) Multivariate Logistic regression analysis showed that male was an independent related factor for elevated blood Eos (≥0.5×10 9/L) in the early stages of PD ( OR=2.044, 95% CI 1.101- 3.794, P=0.023). (4) Diabetes mellitus ( OR=3.363, 95% CI 1.087-10.405, P=0.035), lower baseline hemoglobin level ( OR=0.941, 95% CI 0.903-0.980, P=0.004) and elevated blood Eos (with serum Eos<0.5×10 9/L as reference, OR=2.917, 95% CI 1.022-8.326, P=0.045) were the independent related factors of early-onset peritonitis. Conclusion:Blood Eos elevations are common in early stage of PD patients , mainly occuring within 6 months after PD catheterization, and most of them are slightly increased and last less than 3 months. Male sex is an independent related factor for the elevation of blood Eos in the early stage of PD. Elevated blood Eos is an independent related factor for early-onset peritonitis.

A method was developed for determination of dilauryl thiodipropionate(DLTDP)in fried foods by coupling solid-phase extraction(SPE)pretreatment with reverse-phase liquid chromatography-tandem mass spectrometry(RPLC-MS/MS)detection.Samples were extracted with n-hexane as the solvent,purified using a neutral alumina SPE cartridge,and finally analyzed by RPLC-MS/MS.Quantitative analysis was performed using matrix-matched calibration curves combined with an external standard method under optimal experimental conditions.The results showed that DLTDP exhibited good linearity in the range of 2.0-50.0 μg/L,with a correlation coefficient(R2)≥0.999.The limit of detection(LOD)and the limit of quantification(LOQ)of the method were 0.15 mg/kg and 0.5 mg/kg,respectively.The mean recoveries at three fortification levels(0.5,1.0,and 200 mg/kg)in different samples ranged from 84.8%to 96.8%,with the relative standard deviations(RSDs)all less than 8.0%.The developed method was highly sensitive,accurate and reliable,and easy to operate,making it well suited for the routine quantitative analysis of DLTDP in fried foods.

Objective:Peritoneal dialysis(PD)-associated peritonitis is a common and major complica-tion of PD and the most common cause of technical failure of PD.The presence of bacterial biofilm may be an important factor leading to refractory or recurrence of peritonitis.To investigate the formation and characteristics of bacterial biofilms on PD catheters after peritonitis-associated catheter removal.Methods:The patients with maintenance PD who were regularly followed up in the Peking University People's Hospital from June 2007 to January 2022 were retrospectively analyzed.The patients who with-drew from PD because of peritonitis and removed the PD catheter in our hospital and underwent the scan-ning electron microscope examination of the catheter were selected.The general information of the pa-tients,the electron microscope results of the PD catheter and the bacterial culture results of the PD fluid were summarized.Results:(1)A total of 18 patients were included,11 were female(accounting for 61.1％).The average age of the patients was(59.1±11.5)years,and the average duration of dialysis was(80.1±47.4)months.Primary kidney diseases were predominantly chronic glomerulonephritis(55.6％),followed by diabetic nephropathy(27.8％),and others(16.6％).The reasons for cathe-ters removal in 18 patients were refractory peritonitis in 11 cases,recurrent peritonitis in 5 cases,and fungal peritonitis in 2 cases.(2)16 of the 18 patients(88.9％)had catheter bacterial biofilm,and the bacterial biofilm forms were all cocci.Some were arranged in grape-like shapes,and their diameters ranged from about 500 nm to 1 000 nm.The bacterial culture results of peritoneal dialysis fluid showed that the three most common pathogens were Escherichia coli,methicillin-sensitive Staphylococcus aureus(MSSA),and Staphylococcus epidermidis.(3)Among the 18 patients enrolled,13 patients(72.2％)had peritonitis in the past.The causative bacteria of peritonitis in 9 patients were cocci,including coagu-lase-negative Staphylococci(Staphylococcus suis,Staphylococcus surface,Staphylococcus xylosus,Staphy-lococcus warneri),Staphylococcus aureus,Streptococcus(Streptococcus salivarius and Aerococus viridans).Conclusion:Bacterial biofilm formation on the inner surface of PD catheter is common in peritonitis-asso-ciated catheter removal patients.Not all PD catheters removed due to peritonitis have bacterial biofilms.Bacterial biofilms and peritonitis pathogens may not be consistent.

Objective To explore the potential pathogenic genes of intestinal metaplasia.Methods Twenty-one patients with intestinal metaplasia admitted to the Department of Gastroenterology at the Second Affiliated Hospital of Anhui University of Chinese Medicine from January,2022 to June,2022,and 21 healthy subjects undergoing gastroscopic examination during the same period were enrolled in this study.All the participants underwent gastroscopy and pathological examination,and gastric tissue samples were collected for transcriptome sequencing to screen for differentially expressed genes(DEGs).The biological functions of the DEGs were analyzed using bioinformatics analysis,and qRT-PCR was used to validate the results.Results Transcriptomic sequencing identified a total of 1373 DEGs,including 827 upregulated and 546 downregulated ones.The top 6 upregulated genes(AGMAT,CCL25,FABP1,CDX1,SPINK4,and MUC2),ranked based on their significance and average expression level,were selected for validation,and qRT-PCR showed significant upregulation of their mRNAs in the gastric tissues of patients with intestinal metaplasia(P<0.05).Conclusion AGMAT,CCL25,FABP1,CDX1,SPINK4,and MUC2 participate in the occurrence and development of intestinal metaplasia,and may serve as potential biomarkers for diagnosing intestinal metaplasia.

UDP glycosyltransferase (UGT) is a terminal modifying enzyme for the formation of flavonoid glycosides. In this study, we obtained two glycosyltransferase genes, CtUGT25 and CtUGT18, which are closely related to the synthesis of safflower flavonoids, through the Pierce correlation analysis of the expression of glycosyltransferase genes in the safflower corolla transcriptome database at different developmental stages with the contents of the major constituents of safflower metabolome database, and bioinformatically analyzed the gene and protein sequences of the two genes. Expression pattern analysis revealed that CtUGT25 was mainly expressed in the corolla, with the highest expression on day 3 of flowering stage; CtUGT18 was mainly expressed in the root, with the highest expression on day 1 of flowering stage. Functional validation was verified in safflower by Agrobacterium-mediated pollen-tube pathway transgenesis method, demonstrating that CtUGT25 promoted the accumulation of kaempferol-3-O-glucoside and hydroxysafflor yellow A (HSYA), and CtUGT18 promoted the accumulation of kaempferol-3-O-glucoside and orientin, both of which may be the glycosyl-modifying enzymes for the synthesis of safflower flavonoids. Meanwhile, in vitro experiments demonstrated the catalytic activity of CtUGT25 protein on naringenin, quercetin, apigenin, kaempferol, luteoin, 2-hydroxynaringenin and galangin. This study serves as reference for future advancements in regulating the quality of safflower using molecular biotechnology, particularly focuses on the industrial production of safflower exclusive component HSYA. Additionally, it offers valuable insights for researching related genes in other plants.

This study design of specific identification primers for the ITS2 sequence of F. ussuriensis. The reaction system and conditions were optimized, and PCR-nucleic acid test strips were constructed to realize the visual detection of F. ussuriensis Bark. Through molecular cloning and sequencing technology, we constructed a positive control for F. ussuriensis DNA and formulated quality standards. The established method was evaluated for sensitivity, specificity and reproducibility, and the authenticity of the commercially available samples was identified. Results demonstrated that based on the ITS2 sequences, F. ussuriensis and its mixed forgeries could be distinguished. The PCR products of the authentic F. ussuriensis on test strips showed two bands in the T and C lines, while the pseudo products and negative control showed only one band in the C line, which was consistent with the results of agarose gel electrophoresis. The specificity was 100%, and the sensitivity of the PCR-nucleic acid test strip was up to 0.1 ng·μL^-1, which was 10 times higher than that of the gel electrophoresis assay. 11 out of 16 commercially available samples of F. ussuriensis were qualified, and 5 were unqualified. Collectively, the PCR-nucleic acid test strip method established in this study is specific, rapid, accurate and visualized, which can provide a new technical idea for the detection of F. ussuriensis.
