ObjectiveTo investigate the mechanism of Xiezhuo Jiedu prescription in the treatment of ulcerative colitis （UC） by inhibiting ferroptosis and alleviating intestinal mucosal injury based on the nuclear factor E₂ related factor 2/solute carrier family 7 member/glutathione peroxidase 4 （Nrf2/SLC7A11/GPX4） signaling pathway. MethodsA total of 60 male SD rats were divided into a normal group， a model group， high- and low-dose Xiezhuo Jiedu prescription groups （26.64 and 13.32 g·kg^-1， respectively）， a ferroptosis inhibitor group （Ferrostatin-1， 0.005 g·kg^-1）， and a mesalazine group （0.27 g·kg^-1）， with 10 rats in each group. A UC rat model was established by intrarectal administration of trinitrobenzene sulfonic acid （TNBS）-ethanol. The normal group and the model group were intragastrically administered normal saline. The other groups were given intragastric administration according to the corresponding dosage for 7 d. The general condition， disease activity index （DAI） score， colon length， and mucosal injury index （CDMI） score were observed in each group. The pathological changes of colon tissue in each group were observed by hematoxylin-eosin （HE） staining. The intestinal mucosa and mitochondrial morphology in each group were observed by transmission electron microscopy. The expression levels of Occludin， Claudin-1， mucin 2 （MUC2）， and E-cadherin in intestinal tissue were detected by immunofluorescence （IF）. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression levels of serum tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-10 （IL-10） in each group， and a lactic acid assay kit or ELISA was employed to detect the expression levels of reactive oxygen species （ROS）， ferrous ions （Fe²⁺）， glutathione （GSH）， malondialdehyde （MDA）， 4-hydroxynonenal （4-HNE）， diamine oxidase （DAO）， and D-lactate （D-LA）. Real-time quantitative polymerase chain reaction （Real-time PCR） was applied to detect the mRNA expression levels of Nrf2， SLC7A11， GPX4， Occludin， Claudin-1， MUC2， and E-cadherin in each group， and Western blot was adopted to detect the protein expression levels of Nrf2， p-Nrf2， SLC7A11， and GPX4 in each group. ResultsCompared with the normal group， rats in the model group exhibited listlessness， sluggish response， and mucopurulent and bloody stools. The model group also showed significantly increased DAI score， colon length， CDMI score， and expression levels of TNF-α， IL-6， ROS， Fe²⁺， MDA， 4-HNE， DAO， and D-LA （P<0.01）. In addition， it presented significantly decreased IF values of Occludin， Claudin-1， MUC2， and E-cadherin and mRNA and protein expression levels of IL-10， GSH， Nrf2， p-Nrf2， SLC7A11， and GPX4 （P<0.01）. There were different degrees of improvement in each administration group after treatment， and the improvement was the most significant in the high-dose Xiezhuo Jiedu prescription group （P<0.01）. ConclusionXiezhuo Jiedu prescription may alleviate intestinal mucosal injury by inhibiting ferroptosis of intestinal epithelial cells via regulating the Nrf2/SLC7A11/GPX4 signaling pathway， thereby exhibiting efficacy in the treatment of UC.

This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

In the context of an aging society,the number of elderly cancer patients is constantly increasing,and geriatric oncology has garnered significant attention in recent years.Given the heterogeneity in the health status of older patients,it has become increasingly important to provide individualized diagnosis,treatment,follow-up,and care.Thus,it must be emphasized the Comprehensive Geriatric Assessment(CGA)for elderly patients,which encompasses their physical function,nutritional status,cognitive function,emotional state,comorbidities,polypharmacy,social situation,and treatment preferences.This article provides consensus recommendations on CGA tools for elderly patients prior to anticancer treatment,offering valuable references and insights for clinical practice in China.

BACKGROUND:At present,there are some limitations in evaluating the severity of acute spinal cord injury,and a rapid and accurate evaluation method is urgently needed. OBJECTIVE:To analyze the correlation between the expression levels of serum oxidative stress and nerve injury indexes and the severity of the disease in patients with acute spinal cord injury. METHODS:A total of 65 patients were included in the study from August 2020 to May 2022,including 32 patients in the experimental group(acute spinal cord injury)and 33 patients in the control group(simple spinal fracture).American Spinal Injury Association(ASIA)Impairment Scale and neurological function score were evaluated within 8 hours of admission.Meanwhile,serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were detected and compared between the two groups.The correlation between the expression levels of the above serological indicators in serum and ASIA impairment grade and AISA neural function score was analyzed. RESULTS AND CONCLUSION:The average serum levels of superoxide dismutase and glutathione in the experimental group were significantly lower than those of the control group(P<0.001),while the average serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in the experimental group were higher than those of the control group(P<0.01).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with the damage grade of AISA(r=0.862 4,0.849 3,P<0.01),while the serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with the damage grade of AISA(r=-0.866 1,-0.638 1,-0.746 6,P<0.001),and the serum level of nitric oxide was not significantly correlated with the damage grade of AISA(r=-0.177 5,P>0.05).The serum level of glutathione in the experimental group was positively correlated with AISA sensory function scores(r=0.569 9,P<0.001),while the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA sensory function scores(r=-0.574 1,-0.099 2,-0.708 6,P<0.05),and the serum levels of superoxide dismutase and nitric oxide were not significantly correlated with AISA sensory function scores(r=0.230 8,-0.376 2,P>0.05).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with ASIA motor function scores(r=0.380,0.524 7,P<0.05);the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA motor function scores(r=-0.577 9,-0.452 2,-0.662 8,P<0.05);and the level of nitric oxide had no significant correlation with AISA motor function scores(r=-0.049 7,P>0.05).To conclude,the serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in serum of patients with acute spinal cord injury are significantly correlated with ASIA impairment grade and ASIA neural function score,which could be used as biomarkers for early clinical assessment of disease severity.

Objective:To examine the impact of intrinsic capacity(IC), comorbidity, and their interaction on the occurrence of adverse outcomes in community-dwelling older adults.Methods:This 2-year observational cohort study included 230 residents aged 75 and above who lived in the Beijing Taikang Yanyaun community active area from June to August 2018.The study evaluated the IC scale, Charlson comorbidity index(CCI), and activity of daily living(ADL).In September 2020, adverse outcomes such as functional decline(defined as a decline of at least one point on the ADL scores at 2-year follow-up compared with baseline)and falls were assessed.The structure equation model(SEM)path analysis was employed to examine the direct and indirect effects of IC and CCI on adverse outcomes.Results:Among the 212 older adults who completed a 2-year follow-up, aged 75-93(mean age 83.8±4.4)years, 59.4%(126 cases)were female.Out of these participants, 51.4%(109 cases)experienced functional decline and 33.5%(71 cases)had falls.Path analysis revealed that the direct effects of IC on functional decline and falls were significantly positive, with standardized coefficients of 0.430 and 0.369, respectively.However, the effect of CCI was not found to be significant.The multi-variable Logistic regression model showed that the total effect of IC on functional decline and falls remained significantly positive, with values of 1.184 and 0.915, respectively.CCI acted as a mediating factor, with indirect effects on functional decline and falls accounting for 5.4% and 0.8%, respectively.In terms of the relationship between age and adverse outcomes, the indirect effect of IC was significantly higher than that of CCI(functional decline: 0.192 vs.0.037; falls: 0.158 vs.0.017). Conclusions:The maintenance of IC in the health management of community-dwelling older adults should be given more attention as it can significantly affect the incidence of functional decline and falls.Comorbidity, on the other hand, has a weaker influence.

Background and purpose:Long non-coding RNA(lncRNA)LINC01410,with a length of 647 bp,participates in a variety of tumor biological processes.However,the role and mechanism of LINC01410 involved in esophageal squamous cell carcinoma(ESCC)remain unclear.This study aimed to explore the potential mechanism of LINC01410 promoting ESCC proliferation and invasion,to provide a potential prognostic indicator and therapeutic target for individuals with ESCC.Methods:Gene Expression Profiling Interactive Analysis 2(GEPIA2)databases were used to analyze the expression of LINC01410 and overall survival in esophageal squamous cell carcinoma data set in the Cancer Genome Atlas(TCGA).Gene Set Enrichment Analysis(GSEA)was performed to identify the underlying signaling pathways involved in the biological effects of LINC01410 in ESCC.A total of 62 pairs of ESCC tissues and paracancerous tissues from ESCC patients who underwent radical surgery in the Department of Thoracic Surgery at the First Affiliated Hospital of Xinxiang Medical College and the First People's Hospital of Pingdingshan City from January 2020 to December 2021 were collected.This project has been approved by the Hospital Ethics Committee(First Affiliated Hospital of Xinxiang Medical College,No.2018036;First People's Hospital of Pingdingshan City,No.2019-018).The expression of LINC01410 in ESCC tissues was detected by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR).We transfected EC109 cells with LV-NC or LV-over/LINC01410 and EC9706 cells with shRNA-NC or shRNA-LINC01410.Stable transfected cells(EC109/NC,EC109/OE,EC9706/NC and EC9706/KD)were selected in primary cell culture medium containing puromycin.The expression of LINC01410 was detected by RTFQ-PCR.The impact of LINC01410 on ESCC cell proliferation was determined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and colony formation assays.The effect of LINC01410 on ESCC cell invasion was detected by transwell migration assay.T cell factor/lymphoid enhancer factor 1(TCF/LEF1)luciferase reporter assay was performed to validate the effect of LINC01410 on the activity of canonical Wnt/β-catenin signaling pathway.The expressions of Wnt/β-catenin and epithelial-mesenchymal transition(EMT)signal pathway related proteins in ESCC cells were detected by Western blot.Results:By analyzing the LINC01410 expression from ESCC samples in TCGA by GEPIA2,we found LINC01410 was consistently increased in ESCC tumors compared with normal tissues(P＜0.05),and high LINC01410 expression was associated with poorer overall survival(OS).RTFQ-PCR assay showed that expressions of LINC01410 were higher in esophageal cancer tissues and esophageal cancer cells(EC109 and EC9706)than in precancerous tissues and HEEC cells(P＜0.05).The expression level of LINC01410 was significantly correlated with invasion range,lymph node metastasis and TNM stage in ESCC patients(P＜0.01).LINC01410 expression was also upregulated in EC109/OE,however the expression of LINC01410 in EC9706/KD was decreased(P＜0.01).MTT assay showed overexpression of LINC01410 increased the viability of EC109 cells,while knockdown of LINC01410 decreased the viability of EC9706 cells(P＜0.01).Colony formation assay indicated that overexpression of LINC01410 enhanced the clonogenic ability of ESCC cells,while knockdown of LINC01410 reduced colony formation(P＜0.01).Transwell migration assay showed that LINC01410 overexpression drastically increased the number of migratory cells,while silencing of LINC01410 suppressed the migration in EC9706 cells(P＜0.01).GSEA revealed that Wnt/β-catenin and EMT pathways were significantly enriched in ESCC samples with a high level of LINC01410.TCF/LEF1 luciferase reporter assay showed higher levels of Wnt-dependent activities were observed in EC109/OE cells,whereas silenced LINC01410 in EC9706 cells led to contrary results(P＜0.01).Western blot analysis showed that overexpression of LINC01410 in EC109 cell significantly increased the expression levels of N-cadherin,β-catenin,cyclin D1,c-Myc and decreased E-cadherin expression,while knockdown LINC01410 resulted in opposite results.Conclusion:LINC01410 promotes proliferation and metastasis of ESCC,which might be caused by activation of Wnt/β-catenin and EMT signaling pathways.

Objective To propose a family-centred health education program for family caregivers of Autistic children and investigate its clinical value.Methods Delphi method was used to establish a family-centred Autistic children care program for family caregivers looking after the Autistic children,which involved two rounds of expert consultation.The pre-and post-control method for different cases was employed in the study.Forty Autistic caregivers in our hospital from January 2022 to October 2022 were assigned to the control group and another 40 in our hospital from November 2022 to January 2023 were assigned to the observation group.The family caregivers of Autistic children in the control group received traditional care education,while those in the observation group was managed with the family-centred Autistic children health education program.The two groups were compared in terms of care burden,knowledge of health education,and evaluation of clinical symptom of Autistic children.Results The expert authority coefficient of the first round of expert consultation was 0.875 respectively and those in the second round was 0.900,respectively.The coefficient of variation of the coordination degree of each index was 0.04-0.20.Kendalls W scores of the two rounds were 0.794 and 0.786,respectively.A health education program for family-centred Autistic children caregiver was established to consist of three subjects:caregiver training,family-centred parental care and activation of positive emotions of autistic caregivers.Autism caregivers in both groups had completed the study.In comparison with the control group,the care burden of the observation group was significantly lower,the knowledge of health education was significantly higher,and the evaluation of children's clinical symptoms was better among the family caregivers of autistic children in the observation group(all P<0.05).Conclusions The family-centred autistic children care program for family caregivers is scientific and applicable.It is conducive to providing health education guidance for family caregivers of Autistic children,effectively reducing the care burden and enhancing the knowledge of health education.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).
