Objective:To investigate the current situation of coping styles in Crohn's disease patients and its related influencing factors.Methods:A total of 80 patients with Crohn's disease admitted to our hospital from Apri 2021 to Dec 2022 were selected to evaluate their coping styles with a simple coping style questionnaire,and relevant data were collected.The factors affecting the coping styles of Crohn's disease were analyzed by multivariable logistic regression.Results:Among the 80 patients,29 cases were negative coping,the incidence was 36.25% .There were 51 patients with positive coping(63.75% ).Educational level,simplified Crohn's disease activity index(CDAI)score,adverse psychology,social support and type D personality were associated with negative coping(P＜0.05).Gender,age,family history,working status,monthly family income,place of residence,and marital status were not associated with negative coping in patients with Crohn's disease(P＞0.05).Multivariable logistic regression analysis showed that education level of high school or below(OR=2.945,95% CI:1.139-7.614),higher CDAI score(OR=11.999,95% CI:4.387-32.815),poor psychology(OR=5.950,95% CI:2.180-16.239),low social support(OR=3.598,95% CI:1.370-9.448)and type D personality(OR=3.208,95% CI:1.118-8.904)were risk factors for negative coping in patients with Crohn's disease(P＜0.05).Conclusions:The incidence of negative coping in patients with Crohn's disease is higher,which is related to high school education or below,high CDAI score,poor psychology,low social support,and type D personality.Therefore,clinical measures can be taken to promote patients to actively cope with the disease.

OBJECTIVE To investigate the mechanism of anti-colorectal cancer growth and metastasis-related effects of Astraga-lus mongholicus Bunge-Curcuma aromatica-Paridis Rhizoma(Qi-Zhu-Zao)pairing through PERK/eIF2α/ATF4 signaling pathway mediating endoplasmic reticulum stress.METHODS Twenty-four BALB/c male mice were randomly divided into sham-operated group,model group,5-FU(5-fluorouracil)group(25 mg·kg-1),and Qi-Zhu-Zao high dose group(5.85 g·kg-1),Qi-Zhu-Zao low dose group(2.925 g·kg-1)(n=6)to construct a mouse model of colorectal cancer in situ transplantation tumor,and the inter-vention effect of Qi-Zhu-Zao combination on tumor growth was assessed by the change of tumor volume size after 15 days of administra-tion;the intervention effect of Qi-Zhu-Zao combination on tumor growth was assessed by H&E.Pathological staining was used to eval-uate the effect of Qi-Zhu-Zao combination on the liver and tumor tissues of mice.The changes of MDA,SOD and GSH-Px levels were detected by enzyme-linked immunosorbent assay(ELISA);the expression of PERK/eIF2α/ATF4 signaling pathway and EMT-related proteins were detected by protein immunoblotting(Western blot).RESULTS Compared with the model group,the tumor volume was significantly reduced(P＜0.000 1),liver and spleen metastases were less pronounced in the Qi-Zhu-Zao high-dose group,and his-topathological staining results of liver tissue and tumor produced changes in oxidative stress indicators SOD,MDA,and GSH-Px,up-regulation of ER stress-related proteins p-PERK,p-IF2α,and ATF4,etc.,upregulated the protein expression levels of E-Cadherin,downregulated N-Cadherin,Vimentin,and Snail,and inhibited the EMT process(P＜0.01 or P＜0.05).CONCLUSION In this paper,we investigated the regulatory mechanism related to the inhibition of colorectal cancer growth and metastasis by the combination of Qi-Zhu-Zao trigonal medicine,and demonstrated that it may inhibit the growth and metastasis of colorectal cancer by activating the PERK/eIF2α/ATF4 pathway to induce sustained ER stress and affect the EMT process of colorectal cancer.

Objective To investigate the effect of dietary intake on the childbirth outcomes of primipara women with full-term labor analgesia. Methods A total of 400 primipara women with full-term labor analgesia were randomly divided into observation group and control group. The observation group received intake management and individualized dietary guidance, while the control group ate and drank according to their own wishes. The childbirth quality, the incidence of vomiting, the use of oxytocin due to uterine atony, the rate of intrapartum fever, the rate of perineal incision, the rate of cesarean section, the rate of vaginal assisted delivery, and the rate of postpartum hemorrhage were compared between the two groups. The duration of the first stage of labor, the duration of the second stage of labor, the duration of labor analgesia, and the amount of postpartum hemorrhage within 2 hours were also compared. Neonatal Apgar score, random blood glucose, umbilical artery blood pH value, umbilical artery blood lactic acid (Lac) value, the incidence of neonatal asphyxia, the incidence of neonatal fever, and the incidence of neonatal hypoglycemia were compared between the two groups. Results The observation group had lower incidences of vomiting, oxytocin use rate due to uterine atony, intrapartum fever rate, perineal incision rate, transferring cesarean section rate, and vaginal assisted delivery compared to the control group(P < 0.05). The observation group had lower rates of postpartum hemorrhage, shorter duration of the first and second stages of labor, shorter duration of labor analgesia, and less postpartum hemorrhage within 2 hours compared to the control group, and the incidences of neonatal hyperglycemia and hypoglycemia in the observation group were lower than those in the control group (P < 0.05). There were no statistically significant differences in umbilical artery blood pH value, Lac value, neonatal Apgar score, random blood glucose, neonatal asphyxia rate, and neonatal fever rate between the two groups (P>0.05). Conclusion Intake management and individualized dietary guidance during labor can reduce the incidence of uterine atony, shorten the duration of labor, decrease the incidence of dystocia, reduce postpartum hemorrhage within 2 hours and decrease the incidence of neonatal glucose abnormality.

OBJECTIVES: The development and validation of the specific health literacy assessment tool for older adults is the basis for conducting the research on health literacy among older adults. The existing health literacy assessment scale for older adults in Chinese mainland has some limitations, such as too many items and poor compliance during the survey. It is necessary to develop or introduce simplified assessment tools to support large-scale surveys in the future. This study aims to modify the brief health literacy assessment scale compiled by Taiwan scholars, and to conduct the test for the reliability, validity and the measurement equivalence across gender in the older population in mainland China. METHODS: From March to April 2021, 508 older adults from Jinan, Shandong Province, China were selected by cluster sampling method to conduct a questionnaire survey using the brief health literacy assessment scale and health-promoting lifestyle profile. After 4 weeks, 83 of them were selected for retesting. SPSS 25.0 statistical software was used for descriptive analysis, item analysis, exploratory factor analysis, correlation analysis, and reliability test, and Mplus 8.0 was used for confirmatory factor analysis and gender measurement equivalence test. RESULTS: Each item of the scale had good discrimination, and there were significant differences in the scores of each item between high score and low score groups (P<0.05), and the coefficient of correlation between the scores of each item and the total score was between 0.721 and 0.891. Exploratory factor analysis extracted a factor with a characteristic root greater than 1, and the cumulative variance interpretation amount was 67.94%. The confirmatory factor analysis showed that the single factor structure fit was good [χ2/df was 2.260, the Tucker-Lewis index was 0.973, the comparison fit index (CFI) was 0.982, and the root mean square error of approximation (RMSEA) was 0.071]. The multi-group confirmatory factor analysis results showed that the brief health literacy assessment scale's configural equivalence, weak equivalence, and strong equivalence models were all accepted. The comparison results of measurement equivalence models showed that the changes of RMSEA were less than 0.015, and the changes of CFI were less than 0.01, indicating that the brief health literacy assessment scale had measurement equivalence between different gender groups. Cronbach's α coefficient was 0.945, and the test-retest reliability was 0.946. The correlation coefficient between health literacy and health-promotion lifestyles was 0.557 (P<0.05). CONCLUSIONS The brief health literacy assessment scale has good reliability, validity, and measurement equivalence across gender, and can be used as an effective measurement tool for the health literacy of the older people in Chinese mainland.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Electromagnetic stimulation is an important neuromodulation technique that modulates the electrical activity of neurons and affects cortical excitability for the purpose of modulating the nervous system. The phenomenon of inverse stochastic resonance is a response mechanism of the biological nervous system to external signals and plays an important role in the signal processing of the nervous system. In this paper, a small-world neural network with electrical synaptic connections was constructed, and the inverse stochastic resonance of the small-world neural network under electromagnetic stimulation was investigated by analyzing the dynamics of the neural network. The results showed that: the Levy channel noise under electromagnetic stimulation could cause the occurrence of inverse stochastic resonance in small-world neural networks; the characteristic index and location parameter of the noise had significant effects on the intensity and duration of the inverse stochastic resonance in neural networks; the larger the probability of randomly adding edges and the number of nearest neighbor nodes in small-world networks, the more favorable the anti-stochastic resonance was; by adjusting the electromagnetic stimulation parameters, a dual regulation of the inverse stochastic resonance of the neural network can be achieved. The results of this study provide some theoretical support for exploring the regulation mechanism of electromagnetic nerve stimulation technology and the signal processing mechanism of nervous system.

Objective:To identify the risk factors for intrapartum fever during labor analgesia and establish the prediction model.Methods:The medical records from pregnant women with intrapartum fever during labor analgesia were retrospectively analyzed. According to whether the highest body temperature ≥38 ℃, the parturients were divided into intrapartum fever group and non-fever group. The general data from patients, duration of hospital stay before labor, induced labor, prenatal hemoglobin concentration, body msaa index (BMI) during pregnancy, artificial rupture of membranes in the incubation period, frequency of vaginal examination and etc. were collected. The risk factors of which P values were less than 0.05 would enter the logistic regression analysis to stratify intrapartum fever-related risk factors, and the weighted score regression prediction model was established. Hosmer-Lemshow Test was used to assess the fit of the model, and the receiver operating characteristic curve was drawn to evaluate the model. The nomogram was drawn for visually presenting the regression model. The clinical calibration curve, decision curve analysis and clinical impact curve were drawn to assess the created prediction model. Results:There were 99 parturients developed fever during labor analgesia, with an incidence of 34.7%. The results of logistic regression analysis showed that duration of hospital stay before labor, prenatal hemoglobin concentrations, BMI during pregnancy, induced labor, artificial rupture of membranes in the incubation period and frequency of vaginal examination were the independent risk factors for intrapartum fever during labor analgesia. The area under the receiver operating characteristic curve was 0.943, 95% confidence interval was 0.916-0.969, the sensitivity was 86.9%, the specificity was 88.6%, and the Youden index was 0.755. The prediction model of the line chart was assessed by Hosmer-Lemshow, P=0.898. Conclusions:Duration of hospital stay before labor, hemoglobin concentrations, BMI during pregnancy, induced labor, artificial rupture of membranes in the incubation period and frequency of vaginal examination are independent risk factors for intrapartum fever during labor analgesia in parturients, and the risk prediction model developed can effectively predict the occurrence of intrapartum fever during labor analgesia.

OBJECTIVES: The results of elastic imaging in evaluating the function and histopathological changes of allogeneic renal transplantation are contradictory, one of the important reasons may be that there are differences in human parameters related to kidney transplantation among individuals. The purpose of this study is to explore the related human body parameters on shear-wave elastography (SWE) effects on quantitative stiffness of graft cortex. METHODS: From March 2021 to November 2021, a total of 63 patients with allogeneic kidney transplantation in the Department of Ultrasonography, Third Xiangya Hospital, Central South University, were selected to collect the parameters of two-dimensional, color Doppler and SWE. The subjects were divided into a <20% group and a 20%-30% group according to the variation of cortical hardness measurement. Mann Whitney U test was used to compare the differences in relevant human parameters, and Spearman rank correlation was used to analyze the correlation between relevant human parameters and cortical hardness of transplanted kidney. RESULTS: There was no significant difference between the 2 groups in age, sex, postoperative time, resistance index of interlobar artery, SCr, blood uric acid, ratio of fat layer to muscle layer, and BMI (all P>0.05). Compared with the <20% group, the patients in the 20%-30% group had smaller cortical hardness of the transplanted kidney, greater total distance between the transplanted kidney and the skin surface, and thicker fat layer or muscle layer in front of the transplanted kidney (all P<0.05). The age of patients, the total distance from the transplanted kidney to the skin surface, the thickness of fat layer and muscle layer, the ratio of fat layer to muscle layer, BMI, and the variation of cortical hardness were significantly negatively correlated with the cortical hardness of the transplanted kidney (all P<0.05). CONCLUSIONS Human parameters relevant to kidney transplantation affect the accuracy of SWE in measuring the cortical hardness of the transplanted kidney. It is very important to obtain the highly stabile elastic measurement value and interpret the elastic measurement results according to different levels of human body related parameters in combination with individual conditions.

OBJECTIVES: Patients from different social environments and cultural backgrounds have different nursing needs. If nurses ignore the cultural differences of patients, it is easy to lead to the strained nurse-patient relationship, affect the nursing effect and cause harm to patients. Critical cultural competence (CCC) can help nurses to meet the nursing needs of patients from different cultural backgrounds, which is beneficial to building a harmonious nurse-patient relationship and improving the quality of nursing. Almutairi, et al designed the Critical Cultural Competence Scale (CCCS) which can be used to evaluate accurately nurses' CCC. No studies have reported the development of a critical cultural competence measurement tool for nurses or the introduction of foreign scales in China. This study aims to conduct Chinese and cross-cultural debugging and test the reliability of the English version of the CCCS in order to form CCCS suitable for Chinese cultural background and provide an effective evaluation tool for investigating the current situation of clinical nurses' CCC. METHODS: This study used Brislin's back-translation model to translate and back-translation the English version of CCCS. The Chinese version of CCCS was then created through cross-cultural debugging by expert consultation and a pre-survey with a sample size of 30 clinical nurses. From August to October 2019, 580 clinical nurses were surveyed using a whole group sampling method. The participants were randomly divided into 2 groups with a 7꞉3 ratio. One group (n=406) was used for exploratory factor analysis and reliability analysis, while the other group (n=174) was used for confirmatory factor analysis. Six experts used the scale-level content validity index (S-CVI) and the item-level content validity index (I-CVI) to assess content validity. In the exploratory factor analysis, items were screened using the critical ratio method, and were tested using the KMO (Kalser-Meyer-Olkin) index, Bartlett's sphericity test, and principal component analysis. In the confirmatory factor analysis, average variance extracted (AVE), goodness of fit index (GFI), adjusted goodness of fit index (AGFI), and root mean square error of approximation (RMSEA) were used to assess the degree of fit of the constructed model. For the total scale and the 4 subscales, the Cronbach's α coefficient, split-half reliability, and retest reliability were used to assess the scale's reliability. RESULTS: The S-CVI was 0.930, while the I-CVI ranged from 0.833 to 0.944. For all items, the critical ratio exceeded 3, and the difference between the high and low subgroups was statistically significant (P<0.05). Exploratory factor analysis revealed critical knowledge subscale had a KMO value of 0.676, with the total scale and other 3 subscales all having a KMO value >0.8 and a chi-square value of 814.32 to 12 442.45 for the Bartlett's spherical test, with degree of freedom ranging from 21 to 136 (P<0.001), indicating that all items were suitable for factor analysis. The principal component analysis showed that 17, 12, 7, and 7 items were extracted from the 4 subscales, with 4, 3, 2, and 2 components whose eigenvalues were more than 1, and the cumulative variance contribution was 66.0%, 54.3%, 56.6%, and 70.2%, respectively. The confirmatory factor analysis showed that the AVE of the 4 subscales were 0.637, 0.499, 0.560, and 0.565, GFI was 0.904, AGFI was 0.863, and RMSEA was 0.076. The Cronbach's α coefficient for the total scale and subscales ranged from 0.811 to 0.878, the split-half reliability ranged from 0.707 to 0.842, and the retest reliability was 0.827. CONCLUSIONS The Chinese version of the CCCS has good reliability and validity, and it can be used as a valid assessment tool for clinical nurses' critical cultural competence in China.
