Objective:To translate the Illness Identity Questionnaire (IIQ) into Chinese and test its reliability and validity.Methods:The English version of IIQ was translated into Chinese and back-translated according to the Brislin model. The item of the Chinese version was determined after cross-cultural adaptation and pre-experiment. A total of 368 patients with IBD treated in the First Affiliated Hospital with Nanjing Medical University from September 2022 to March 2023 were selected for a questionnaire survey to evaluate the reliability and validity of the questionnaire.Results:The Chinese version of IIQ contained 24 items in four dimensions. Four common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.025%. Confirmatory factor analysis showed that each fitting index of the modified model was within the acceptable range. The Cronbach's α coefficients of rejection, acceptance, engulfing, and enrichment in Chinese IIQ were respectively 0.780, 0.800, 0.921, and 0.917. The split-half reliability coefficients were 0.824, 0.818, 0.943, and 0.929; the retest reliability coefficients were 0.695, 0.667, 0.725, and 0.572, respectively.Conclusions:The Chinese version of IIQ is reliable and valid and can be used to assess illness identity in patients with chronic 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.

Iron is an indispensable nutritional element for human growth and development. It has a protective effect on cardiovascular. The changes and metabolism of iron can affect the physiological and pathological state of the body. Current research has confirmed that iron overload will promote the synthesis of cholesterol and increase lipid metabolism disorders. Lipid metabolic disorders in the body easily induce the occurrence and development of related metabolic diseases, and increase the hidden dangers of the outbreak of relevant risk factors. This article reviews iron and lipid metabolic and other metabolic diseases and natural products to prevent diseases through iron metabolic pathway, which aims to provide more powerful references for in-depth research on the mechanism of metabolic diseases and related diseases and target drug research and development.

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 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.

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.

Objective:To analyze the current status of lung cancer screening among residents in Urban Beijing Cancer Screening Program, 2014-2019.Methods:Based on an on-going cancer screening program launched by the National Urban Cancer Screening Program, residents aged 40 to 69 were recruited from 80 streets in six districts of Beijing (Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai, and Shijingshan District) by using a cluster sampling method. Subjects who were evaluated as high-risk individuals by using the questionnaire received Low-Dose spiral Computed Tomography (LDCT) screening in designated hospitals. All participants were followed up annually using active and passive follow-up methods to obtain their health outcomes (diagnosed with lung cancer or not). The proportion of high-risk cases evaluated by using the questionnaire, clinical recall rate for receiving LDCT screening, the proportion of cases with positive pulmonary node, incidence rate, cumulative incidence rate, and the proportion of patients with stage 0 or Ⅰ were calculated. Cox proportional hazard regression model was used to estimate the hazard ratio ( HR) and 95% confidence interval (95% CI) among individuals who experienced different screening scenarios. Results:A total of 88 044 residents with the age of (57.4±7.4) with completed high-risk assessment were included in the analysis. 23.14% of participants were evaluated as high-risk individuals by using the questionnaire. The clinical recall rate was 52.26% among the high-risk individuals. The positive rate of pulmonary node detected by LDCT was 10.99%. The incidence rate of lung cancer among males and females aged 40-69 years were 172.82/100 000 person-years and 133.52/100 000 person-years, respectively after 3 years follow-up. The incidence rates increased with age ( P trend<0.001). The incidence rate of lung cancer among high-risk individuals was 259.22/100 000 person-years, with the HR ( 95%CI) about 2.27 (1.83-2.81) when compared with that among low-risk individuals. The incidence rate and cumulative incidence rate of lung cancer among individuals with positive pulmonary node detected by LDCT were 1 825.03/100 000 person-years and 4 615.38/100 000, respectively, with the HR (95% CI) about 13.80 (8.91-21.36) when compared with that among individuals with no or negative pulmonary node. The early diagnosis rate among individuals who received LDCT screening was 70.21%, which was higher than that among individuals with no LDCT screening (45.45%). Conclusion:Individuals with a high risk of lung cancer in Beijing have a better recall rate of receiving LDCT screening. Using LDCT screening among high-risk individuals is an effective strategy to detect lung cancer cases and improve the early detection rates of lung cancer in Beijing, China.

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.
