Coronaviruses (CoVs) are generally associated with respiratory and enteric infections and have long been recognized as important pathogens of livestock and companion animals. Mouse hepatitis virus (MHV) is a widely studied model system for Coronavirus replication and pathogenesis. In this study, we created a MHV-A59 temperature sensitive (ts) mutant Wu"-ts18(cd) using the recombinant vaccinia reverse genetics system. Virus replication assay in 17C1-1 cells showed the plaque phenotype and replication characterization of constructed Wu"-ts18(cd) were indistinguishable from the reported ts mutant Wu"-ts 18. Then we cultured the ts mutant Wu"-ts 18(cd) at non-permissive temperature 39.5℃, which "forced" the ts recombinant virus to use second-site mutation to revert from a ts to a non-ts phenotype. Sequence analysis showed most of the revertants had the same single amino acid mutation at Nsp16 position 43. The single amino acid mutation at Nsp16 position 76 or position 130 could also revert the ts mutant Wu"-ts 18 (cd) to non-ts phenotype, an additional independent mutation in Nsp13 position 115 played an important role on plaque size. The results provided us with genetic information on the functional determinants of Nsp16. This allowed us to build up a more reasonable model of CoVs replication-transcription complex.

Objective:To explore the effect and mechanism of miRNA sponge on the epithelial-mesenchymal transition (EMT) of gastric carcinoma cell lines SGC7901. Methods:Synthetic ZEB2 3'UTR plasmid and siRNA targeting ZEB2 were transfected into the SGC7901 cell line by Lipofectamine 2000. Real-time quantitative polymerase chain reaction was performed to evaluate the expres-sion levels of miR-200a/b/c. Finally, the migratory, invasive, and proliferative activities of the gastric carcinoma cells in vitro were ana-lyzed by the scratch test, the Transwell cell invasion, and the cell cloning assay. The expression of the target protein was detected by Western blot. Results:Compared with the control group, the expressions of miR-200a/b/c significantly decreased, and their migration, invasion, and proliferation capabilities were considerably higher after they were transfected with ZEB2 3'UTR. Although the expres-sions of miR-200a/b/c significantly increased, the migratory, invasive, and proliferative activities of SGC7901 cells also degraded after they were transfected with siRNA targeting ZEB2. The expression of ZEB2 increased, and that of E-cadherin decreased at the protein level after they were transfected with ZEB2 3'UTR. The protein expression of Vimentin in SGC7901 cells significantly increased. The indicators show the opposite trend when cells were transfected with siZEB2, and the differences between the control and mutation groups were insignificant. Conclusion:ZEB2 3'UTR can regulate EMT course by regulating the miR-200a/b/c expression in gastric car-cinoma, consequently regulating the invasion and migration of carcinoma cells.

Objective To investigate the effects of isoflurane anenthesia on myocyte enhancer factor 2(MEF2) signaling pathway in neonatal rat hippocampus. Methods Twenty-four 5-day-old SD rats of both sexes,weighing 10-13 g, were randomly divided into 2 groups ( n = 12 each): control group (group C) and isoflurane group (group I). In group I, 1.5% isoflurane in 100% O2 was inhaled for 6 h. Group C received no treatment.Three rata in each group were sacrificed at 2, 4, 6 h of isoflurane anenthesia and 24 h after isoflurane anenthesia (T1-4), and the hippocampi removed for determination of MEF2 mRNA, synGAP Ⅰ mRNA, Arc mRNA and synapsinⅠ mRNA expression (by PT-PCR) and synapsin Ⅰ protein expression (by Western blot).Results Compared with group C, the expression of MEF2 mRNA, synGAP Ⅰ mRNA, Arc mRNA and synapsin Ⅰ mRNA at T1-3 and synapsin Ⅰ protein at T2-4 was up-regulated in group I ( P ＜ 0.05). Conclusion Inhalation of anaesthetic concentration of isoflurane may affect synapse formation during the development of central nervous system by actirating hippocampal MEF2 signaling pathways in neonatal rats.

Objective To explore the effects of zinc finger E-box binding protein (ZEB)2 3′UTR gene transfection on proliferation, invasion and migration in human gastric epithelial cell line GES-1. Methods The synthetic ZEB2 3′UTR and miR-200b micmics were transfected into GES-1 cell line by lipofectamine 2000. We set up control grop, the mutation group and ZEB2 3′UTR group. Real-time quantitative PCR was performed to evaluate the expression levels of miR-200a/b/c and ZEB1/ZEB2 mRNAs after transfection.And then we set up control group, ZEB2 3′UTR group, ZEB2 3′UTR+negative control group and ZEB2 3′UTR+miR-200b micmics group. The protein expression levels of ZEB1, ZEB2, matrix metallopro-teinases (MMP) 2/9 and proliferating cell nuclear antigen (PCNA) were detected by Western blot assay. The invasion and mi-gration capability were analyzed by transwell assay and wound healing test. MTT assay was used to detect the proliferation ability. Results Compared with control group and mutation group, the expressions of miR-200a/b/c were significantly de-creased, especially for miR-200b. And the expressions of ZEB1/ZEB2 were significantly increased at both mRNA and pro-tein levels after transfected with the ZEB2 3′UTR, enhancing the capability of migration,invasion,and proliferation (P <0.05). Compared with ZEB2 3′UTR group, the capabilities of proliferation,invasion and migration were significantly lower in combined group. Conclusion ZEB2 3′UTR can increase the ability of cell proliferation, invasion and metastasis through regulating the levels of miR-200a/b/c, and then influence the regulation of transcription of the target gene, which could lead to malignant transformation of GES-1 cells.

Objective:To study the reasons of excessive expenses in hospital and explore the segmented management of the cost of DRG group.Methods:Taking the FC35(coronary artery bypass grafting, without complications and comorbidities)as an example, 1 416 patients of FC35 group discharged from the hospital from June to December 2019 were selected. Taking the average cost of the disease group in the tertiary general hospitals of Beijing in 2019 as the benchmark value, the patients were divided into patients with excessive cost and patients without excessive cost. The hospitalization expenses of the two groups were compared and analyzed, the horizontal comparison between departments and the segmented statistics of patients′ expenses were conducted.Results:In the FC35 group, 614 patients(43.36%)had excessive hospitalization costs. Clinical departments B, D and E had the largest number of cases and the overall cost efficiency was better. Operating room and anesthesiology expenses accounted for 52.77% of the total cost of patients. The cost of high-value tube, high-value line, high-value other, mesh and sanitary materials in the operating room ranked in the top 5.Conclusions:The cost of high value consumables in the operating room is one of the important reasons for the excessive cost of patients.

After undergoing the long-term lived experience of symptoms and suffering, chronic patients change the understanding of self and try to create or regain a coherent sense of self, resulting in different degrees of illness identity. This research reviewed the origin, connotation, assessment tools, and summarized the performance level, influencing factors and intervention studies of illness identity in patients with chronic disease. It would provide references for research of illness identity, and to provide new ideas for promoting patients with chronic diseases to cope with and manage diseases.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.

The functional coupling between motor cortex and effector muscles during autonomic movement can be quantified by calculating the coupling between electroencephalogram (EEG) signal and surface electromyography (sEMG) signal. The maximal information coefficient (MIC) algorithm has been proved to be effective in quantifying the coupling relationship between neural signals, but it also has the problem of time-consuming calculations in actual use. To solve this problem, an improved MIC algorithm was proposed based on the efficient clustering characteristics of K-means ++ algorithm to accurately detect the coupling strength between nonlinear time series. Simulation results showed that the improved MIC algorithm proposed in this paper can capture the coupling relationship between nonlinear time series quickly and accurately under different noise levels. The results of right dorsiflexion experiments in stroke patients showed that the improved method could accurately capture the coupling strength of EEG signal and sEMG signal in the specific frequency band. Compared with the healthy controls, the functional corticomuscular coupling (FCMC) in beta (14~30 Hz) and gamma band (31~45 Hz) were significantly weaker in stroke patients, and the beta-band MIC values were positively correlated with the Fugl-Meyers assessment (FMA) scale scores. The method proposed in this study is hopeful to be a new method for quantitative assessment of motor function for stroke patients.
