Objective:To explore the effect of interactive intelligent system on management effect and the influence of that on data collection for intensive care equipment of hospital.Methods:The interactive intelligent system conducted management intervention for equipment from the intelligent system based on quick response(QR)codes,usage registration,maintenance and upkeep of equipment,warranty and preventive maintenance for fault,training for operator,and status display.Seventy-two intensive care equipment in clinical use in the department of intensive care unit(ICU)of Beijing Tongren Hospital Affiliated to Capital Medical University from March 2021 to February 2023 were selected.The management for equipment during March 2021 and February 2022 adopted the conventional management method.From March 2022 to February 2023,the management for equipment adopted the management of interactive intelligent system(intelligent management method).The management quality,data collection and management effect for equipment between the two management methods were compared.A self-made satisfaction questionnaire was adopted to investigate the satisfaction of managers,who used equipment,for the management after the two management methods were used to conduct intervention.Results:After the intervention with intelligent management method for equipment was implemented,the management quality scores of the equipment of infusion and injection,medical monitoring,rehabilitation and treatment,life support,emergency rescue,and disinfection and sterilization were respectively(93.49±4.51),(94.31±4.89),(92.63±4.34),(95.23±4.12),(94.43±4.39)and(94.56±5.12)points,all which were higher than those of conventional management method,and the differences were statistically significant(t=6.253,5.198,6.149,5.673,5.243,6.029,P<0.05),respectively.The scores of completeness,accuracy,overlap,value and rationality of collecting equipment data of the intelligent management method were respectively(95.63±4.12),(96.23±3.61),(96.11±3.29),(95.45±4.39)and(96.21±3.73),all which were higher than those of the conventional management method,and the differences were statistically significant(t=5.149,5.541,6.292,4.784,5.112,P<0.05),respectively.The costs of component purchase,daily maintenance,personnel management,technical consultation and operation of the intelligent management method were all lower than those of the conventional management method,and the differences were statistically significant(t=4.495,5.237,6.112,5.395,5.676,P<0.05),respectively.The satisfaction of managers,who used equipment,for the intervention of adopting intelligent management method in management method,daily maintenance,repair and prevention,skill improvement and data recording for equipment were higher than those of adopting conventional management method,and the differences were statistically significant(x2=6.263,4.096,6.114,5.945,6.535,P<0.05).Conclusion:The application of the interactive intelligent system in the management for equipment of the department of intensive care unit of hospital can improve the quality of management for equipment,and enhance the effect of collecting data,and reduce the operating cost of equipment,which can achieve a higher satisfaction for management.

Objective:To construct the rpoN gene knockout strain (Δ rpoN) and the complemented strain (CΔ rpoN) of Vibrio vulnificus ( V. vulnificus), and investigate the role of the rpoN gene in regulating bacterial motility and biofilm formation. Methods:The Δ rpoN strain of V. vulnificus was constructed using homologous recombination. Bacterial motility was assessed via swimming assays, and flagellar morphology was observed by transmission electron microscopy. Biofilm formation capacity was evaluated using crystal violet and Congo red staining assays, as well as colony morphology analysis. Real-time quantitative RT-PCR (qRT-PCR) was used to detect mRNA levels of target genes associated with flagellar synthesis and biofilm formation in Δ rpoN and the wild-type strains. Results:The V. vulnificus genome harbored a single rpoN gene, encoding a protein with high amino acid sequence similarity to RpoN homologs in other bacterial species. The Δ rpoN strain was successfully constructed. Compared with the wild-type strain, the Δ rpoN strain exhibited complete loss of motility on soft agar plates, absence of flagellar, and downregulated mRNA levels of flagellar synthesis-related genes. Conclusions:In V. vulnificus, RpoN regulates flagellar assembly by modulating the expression of flagellar synthesis genes, thereby controlling bacterial motility and biofilm formation.

Nonsense-mediated mRNA decay(NMD)is a highly conserved post-transcriptional regulatory mechanism in eukaryotic cells.NMD can recognize and degrade abnormal transcripts con-taining premature termination codons(PTC)to pre-vent the translation of C-terminal truncated pro-teins.Furthermore,NMD could degrade a subset of normal gene transcripts and thus fine-tune gene ex-pression.NMD is essential for cell fate determina-tion,stress response,as well as animal develop-ment.In this review,we briefly discussed the func-tional and molecular mechanisms of NMD pathway activation and inhibition in tumorigenesis,cancer progression and therapy.Current studies indicate that NMD factor mutations can lead to a variety of human tumors.Interestingly,inhibition of NMD fac-tors can activate DNA damage response and inhibit the expression of oncogenic factors,thereby killing cancer cells.This review may provide new perspec-tives for the biological mechanism and therapeutic strategy of human tumors.

Objective:To investigate the effects of platycodon D on proliferation, apoptosis, migration and glycolysis of colorectal cancer HT-29 cell.Methods:Human HT-29 cells were selected and randomly divided into the control group and platycodon D 25, 50, and 100 μmol/L groups. The HT-29 cells in the platycodon D 25, 50, and 100 μmol/L groups were treated with 25, 50, and 100 μmol/L platycodon D for 48 h. The cell proliferation of the cells was examined by cell counting Kit-8 (CCK-8) and colony formation assay. The apoptosis of the cells was investigated using flow cytometry and Western Blot assays were used to examine the expression of apoptosis and apoptosis-related proteins, including B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), and cleaved cystein-asparate protease-3 (cleaved Caspase-3). Transwell and Western Blot assays were used to examine cell migration, glucose consumption, and lactic acid production, as well as the expression levels of pyruvate kinase M2 (PKM2) and phosphorylated PKM2 (p-PKM2) in HT-29 cells.Results:With the increase in treatment time, the proliferation rate of HT-29 cells in the control group and platycodon D 25, 50, and 100 μmol/L groups decreased gradually. Compared with the control group, the viability of HT-29 cells in the platycodon D 25, 50, and 100 μmol/L groups was decreased (all P < 0.001). Compared with the control group, the colony number of HT-29 cells in the platycodon D 25 μmol/L (36 vs. 50), 50 μmol/L (34 vs. 50), and 100 μmol/L (16 vs. 50) groups was decreased (all P < 0.001), after treatment with platycodon D for 24 h. Compared with the control group, the apoptosis rate of HT-29 cells in the platycodon D 100 μmol/L group was increased (62% vs. 39%), the relative expression of Bax was increased (0.9 vs. 0.1), the cleaved Caspase-3 was increased (1.25 vs. 0.15), and the Bcl-2 decreased (0.12 vs. 0.75) (all P < 0.001). Compared with the control group, the per unit vision number of HT-29 cells in the platycodon D 100 μmol/L group decreased (16 vs. 48), the relative expression of Snail decreased (0.5 vs. 1.3), the relative expression of E-cadherin increased (1.2 vs. 0.1), the relative expression of glucose transporter 1 (GLUT1) decreased (0.2 vs. 1.1), the relative expression of lactate dehydrogenase A (LDHA) decreased (0.2 vs. 1.2), and the relative expression of hexokinase 2 (HK2) decreased (0.15 vs. 1.00) (all P < 0.001). Compared with the control group, glucose consumption of HT-29 cells in platycodon D 100 μmol/L group was decreased (1.9 mmol/L vs. 4.8 mmol/L), and lactic acid production was decreased (3.8 mmol/L vs. 9.2 mmol/L) (both P < 0.001). Compared with the control group, the relative expression of PKM2 in the platycodon D 100 μmol/L group was decreased (0.1 vs. 1.0), and the relative level of p-PKM2 was decreased (0.08 vs. 0.75) (both P < 0.001). Conclusions:Platycodon D can inhibit the proliferation of HT-29 cells, promote cell apoptosis, and inhibit cell migration and glycolysis.
