Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Objective To investigate the efficacy of early, short-term, low-dose corticosteroid administration for the prevention and treatment of early acute lung injury (EALI) in patients undergoing thoracoscopic lobectomy. Methods A retrospective analysis was conducted on the clinical data of patients who underwent thoracoscopic lobectomy at the Department of Thoracic and Cardiovascular Surgery, Taihe Hospital, Hubei University of Medicine, from January 2019 to January 2022. Patients were divided into an early steroid therapy group and an observation group based on whether they received corticosteroids in the early postoperative period. In the early steroid therapy group, in addition to standard postoperative care, patients received a low-dose intravenous push of methylprednisolone (80-120 mg/d) for 3 consecutive days. In the observation group, patients received standard postoperative care without intravenous corticosteroids for the first 3 days. Chest plain CT scans were performed on postoperative day (POD) 1 and POD 3 or 4 to evaluate lung injury. CT scores and the incidence of postoperative EALI were recorded. Results A total of 521 patients were included (268 males, 253 females; age range: 11-80 years). There were 318 patients in the observation group and 203 in the early steroid therapy group. On POD 1, the incidence of EALI was 16.0% in the observation group and 13.8% in the early steroid therapy group, with no statistical difference (P=0.486). Correspondingly, there was no statistical difference in chest CT scores among EALI-positive patients between the two groups (P=0.927). On POD 3-4, the incidence of EALI was significantly lower in the early steroid therapy group (22.7%) compared to the observation group (33.6%) (P=0.007). Although chest CT scores among EALI-positive patients were lower in the early steroid therapy group, the difference was not statistically significant (P=0.377). The overall incidence of EALI within the first 4 postoperative days was significantly lower in the early steroid therapy group (26.1%) than in the observation group (37.4%) (P=0.007). Radiological progression (defined as new-onset EALI or progression of existing EALI) occurred in 14.8% of the early steroid therapy group, significantly lower than the 28.9% in the observation group (P<0.001). The early steroid therapy group had a shorter postoperative length of stay (P<0.001), while there was no statistical difference in the incidence of poor wound healing between the groups (P=0.762). Conclusion Early postoperative corticosteroid use effectively reduces the incidence of EALI on POD 3-4, lowers the risk of radiological progression, and decreases the overall incidence of postoperative EALI. This is achieved without prolonging the length of stay or increasing the risk of poor wound healing. Therefore, early administration of low-dose corticosteroids is beneficial in suppressing the occurrence and progression of EALI. Its early use is recommended for patients at high risk for postoperative EALI.

ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

AIM: To investigate the relationship between Apelin and δ-like ligand 4(DLL4)expression levels and clinical stage and efficacy in patients with neovascular glaucoma(NVG).METHODS: A total of 96 NVG patients(96 eyes)who were admitted to our hospital from January 2022 to March 2024(NVG group)and 96 cataract patients(96 eyes)who underwent cataract surgery in our hospital during the same period(control group)were selected. NVG patients were divided into stage Ⅰ group(22 eyes), stage Ⅱ group(47 eyes)and stage Ⅲ group(27 eyes)according to the clinical stage; furthermore, patients were divided into ineffective group(20 eyes)and effective group(76 eyes)according to efficacy. Aqueous humor Apelin and DLL4 levels were detected by enzyme-linked immunosorbent assay. The influencing factors of the efficacy in NVG patients were analyzed by multivariate unconditional Logistic regression analysis, the evaluation efficiency of aqueous humor Apelin and DLL4 levels on the efficacy in NVG patients was analyzed by receiver operating characteristic(ROC)curve.RESULTS: Compared with the control group, aqueous humor Apelin and DLL4 levels in the NVG group were increased(all P<0.001). Aqueous humor Apelin and DLL4 levels in the stage Ⅰ, stage Ⅱ and stage Ⅲ groups increased in turn(all P<0.001). The effective rate of 96 NVG patients was 79.2%(76/96). Compared with the effective group, aqueous humor Apelin and DLL4 levels in the ineffective group increased(all P<0.001). Clinical stage III, high intraocular pressure, high Apelin and DLL4 were independent risk factors for ineffective treatment in NVG patients(all P<0.05). The area under the curve of the combined evaluation of aqueous humor Apelin and DLL4 levels in evaluating the efficacy of NVG patients was 0.874, which was greater than 0.790 and 0.786 of aqueous Apelin and DLL4 levels alone(all P<0.05).CONCLUSION: Aqueous humor Apelin and DLL4 levels in NVG patients increase, which relate to the increase of clinical stage and poor efficacy, and the combination of aqueous humor Apelin and DLL4 levels is more effective in evaluating the efficacy of NVG patients.

Objective:To explore common characteristics and core challenges in the family parenting process of preschool children, identify key issues in parenting practices in rural revitalization areas, and provide a reference for developing localized family intervention strategies in China.Methods:Using purposive sampling, caregivers of preschool children ( n=26) were recruited from a kindergarten in Shuangbai County, Chuxiong Yi Autonomous Prefecture, Yunnan Province, from May to August 2024. A descriptive qualitative research method was adopted. Directed content analysis and conventional content analysis were combined to analyze interview transcripts and family parenting records, extracting core themes and characteristic issues in parenting practices. Results:A total of 881 minutes of interviews were conducted, resulting in approximately 260 000 words of transcripts and text materials. A total of five core themes and 13 sub-themes were summarized, covering access to health information and scientific parenting knowledge, imbalance between parenting needs and objective resource supply, safety care, responsive care, and weak family collaboration systems.Conclusions:Families in rural revitalization areas currently face problems such as limited access to information, insufficient scientific parenting resources, and weak family collaboration functions. It is recommended to optimize parenting practices by deepening the integration of medical and educational resources, strengthening health information channels, and building an integrated "family-school-community" intervention framework.

Objective:To analyze the clinical phenotypes and genetic characteristics of pediatric patients with neurofibromatosis type 1 (NF1).Methods:A cross-sectional study was adopted. Clinical and imaging data of 25 pediatric patients diagnosed as having NF1 in Department of Pediatric Neurology, Linyi People's Hospital Affiliated to Shandong Second Medical University from January 2024 to July 2025 were collected. Whole exome sequencing and Sanger sequencing were used to conduct genetic testing on the pediatric patients and his/her parents. Protein 3D modeling of the domestic and foreign unreported variations was conducted using SWISS-MODEL software.Results:Among the 25 pediatric patients with NF1, 14 were male (56%) and 11 were female (44%), with age ranging from 8 months to 18 years. All pediatric patients exhibited café-au-lait macules, and 7 (28%) presented with plexiform neurofibromas. Genetic test identified 4 types of NF1 variants: nonsense variant ( n=11, 44%), frameshift variant ( n=9, 36%), missense variant ( n=3, 12%), and splice-site variant ( n=2, 8%). Importantly, 5 novel NF1 variants were discovered, including c.3455T>A, c.3709dupG, c.2665_2684del, c.7092_7095delinsTA, and c.3260del. Three pediatric patients inherited NF1 variant from their parents, while the remaining 22 harbored de novo mutation. Conclusion:NF1 exhibits a broad clinical spectrum, primarily affecting the skin and nervous system; this study identifies 5 previously unreported variants, expanding the genetic profile of NF1.

BackgroundPerceived discrimination has been identified as a main risk factor for depression in maintenance hemodialysis patients. Chronic Illness Rejection and Discrimination Scale （CIRDS） is a measure for assessing perceived discrimination in individuals with chronic disease. However， the Chinese version of CIRDS for maintenance hemodialysis patients has not yet been established. ObjectiveTo translate CIRDS into Chinese version and evaluate its reliability and validity in maintenance hemodialysis patients， so as to provide an effective tool for assessing the perceived discrimination among maintenance hemodialysis patients. MethodsThe Brislin's model for translation， back-translation， cross-cultural adaptation and pre-experimentation was utilized to develop a Chinese version of CIRDS. A coherent of 250 maintenance hemodialysis patients attending Taihe Hospital Affiliated to Hubei Medical College， from July to October 2023 were selected as the research subjects. The formal scale was refined by employing item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated using content validity and construct validity. The reliability of the scale was evaluated using Cronbach's α coefficient， test-retest reliability and split-half reliability. ResultsThe Chinese version of CIRDS consisted of 11 items， including 2 factors （perceived discrimination and perceived rejection）. The scale-level content validity index （S-CVI） value was 0.898 and the item-level content validity index （I-CVI） values ranged from 0.875 to 1.000. Two common factors were extracted by exploratory factor analysis and explained 65.41% of the total variance. Confirmatory factor analysis also indicated that the model provided a good fit for the data. The Cronbach's α coefficient of the scale was 0.910， with Cronbach's α coefficients of 0.835 and 0.912 for the perceived discrimination and perceived rejection， respectively. The split-half reliability of the scale was 0.803， and the test-retest reliability was 0.920. ConclusionThe Chinese version of CIRDS has excellent reliability and validity， which can be used to evaluate the perceived discrimination in maintenance hemodialysis patients.

ObjectiveTo analyze the factors influencing meropenem-related liver injury （MRLI） and to explore their clinical predictive value. MethodsA retrospective case-control study was conducted， and the Chinese Hospital Pharmacovigilance System （CHPS） was used to establish a retrieval scheme. A total of 1 625 hospitalized cases using meropenem from January 2018 to December 2022 were collected. Patients were divided into case group （n=62） and control group （n=1 563） based on the presence or absence of liver injury. Clinical data and laboratory indicators from both groups were collected and analyzed. The t-test was used for comparison of normally distributed continuous data between the two groups， while the Mann-Whitney U test was used for comparison of continuous data not conforming to a normal distribution. The chi-square test was used for comparison of categorical data between the two groups. A multivariate Logistic regression analysis was performed to identify the influencing factors for MRLI. A Logistic regression equation was established， and the predictive value of these factors was assessed using the receiver operating characteristic （ROC） curve. ResultsThe results of univariate analysis indicated that the rates of male patients， hypoproteinemia， shock， intensive care unit （ICU） admissions， sepsis， and liver， gallbladder， and cardiovascular diseases， the levels of alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， aspartate aminotransferase （AST）， creatinine （CREA）， and procalcitonin （PCT）， and the number of hospitalization days were significantly higher in the case group than in the control group （P<0.05）， and that the platelet levels in the case group were significantly lower than those in the control group （P<0.05）. The multivariate Logistic regression analysis showed that male sex （odds ratio ［OR］=2.080， 95% confidence interval ［CI］： 1.050 — 4.123， P=0.036）， admission to the ICU （OR=8.207， 95%CI： 4.094‍ ‍—‍ ‍16.453， P<0.001）， comorbidity with gallbladder disease （OR=8.240， 95%CI： 3.605‍ ‍—‍ ‍18.832， P<0.001）， ALP （OR=1.012， 95%CI： 1.004‍ ‍—‍ ‍1.019， P=0.004）， GGT （OR=1.010， 95%CI： 1.005‍ ‍—‍ ‍1.015， P<0.001）， and PLT （OR=0.997， 95%CI： 0.994‍ ‍—‍ ‍0.999， P=0.020） were the influential factors for MRLI. The areas under the ROC curve of ALP， GGT， and PLT were 0.589， 0.637， and 0.595， respectively， and the AUC of them combined was 0.837. ConclusionMale sex， ICU admission， comorbidity with gallbladder disease， increased ALP， increased GGT， and decreased PLT were influencing factors for MRLI， and a combination of factors has a better predictive value for the occurrence of MRLI.

ObjectiveTo elucidate the potential mechanisms by which the classic prescription Anmeidan alleviates cognitive impairment in insomnia model rats through metabolic profiling. MethodsA total of 60 SD rats were randomly divided into six groups： blank group， model group， low-， medium-， and high-dose Anmeidan groups， and the Suvorexant group， with 10 rats in each group. Except for the blank group， the insomnia model was established in all other groups via intraperitoneal injection of para-chlorophenylalanine. The Suvorexant group was administered Suvorexant solution （30 mg·kg^-1·d^-1） by gavage， while the low-， medium-， and high-dose Anmeidan groups received Anmeidan decoction （4.55， 9.09， 18.18 g·kg^-1·d^-1） by gavage. The blank group received an equivalent volume of normal saline. The open field test was used to assess spatial exploration and anxiety/depressive-like behaviors in rats. Serum levels of epidermal growth factor （EGF）， brain-derived neurotrophic factor （BDNF）， and vasoactive intestinal peptide （VIP） were measured using enzyme-linked immunosorbent assay （ELISA）. Untargeted metabolomics was employed to identify differential metabolites in rat serum， and systematic biological methods were applied to analyze the potential targets and pathways of Anmeidan. ResultsCompared to the blank group， the model group exhibited significant reductions in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.01）， along with significant decreases in VIP， EGF， and BDNF levels （P<0.05，P<0.01）. A total of 100 differential metabolites were identified between the model and blank groups. Compared to the model group， the low-， medium-， and high-dose Anmeidan groups showed significant increases in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.05，P<0.01）， as well as a significant increase in VIP levels （P<0.05，P<0.01）. Anmeidan significantly reversed abnormal changes in 67 metabolites compared to the model group. A combined analysis identified 134 potential targets of Anmeidan， with network topology analysis suggesting that Caspase-3， B-cell lymphoma 2 （Bcl-2）， nuclear transcription factor-κB （NF-κB）， interleukin-1β （IL-1β）， interleukin-2 （IL-2）， matrix metalloproteinase-9 （MMP-9）， and Toll-like receptor 4 （TLR4）， among others， may serve as key targets of Anmeidan. Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis revealed major enriched pathways， including the cyclic adenosine monophosphate （cAMP） signaling pathway， hypoxia inducible factor-1 （HIF-1） signaling pathway， and IL-17 signaling pathway. ConclusionThis study demonstrates that Anmeidan can recalibrate abnormal metabolic profiles in insomnia model rats to mitigate cognitive impairment， with its mechanisms of action potentially involving the regulation of immune-inflammatory responses， energy metabolism， and apoptosis-related pathways.

OBJECTIVE To investigate the ultrasound characteristics of category 4 thyroid nodules in the Chinese version of the Thyroid Imaging Reporting and Data System(C-TI-RADS),and to analyze the value of ultrasonography combined with elastography scoring in the correction of nodule properties.METHODS Data from 80 patients with 105 nodules from April 2020 to December 2023 were retrospectively analyzed.Fine-needle aspiration biopsy or surgical pathology was used as the gold standard.The Kappa test was employed to evaluate diagnostic consistency,while the receiver operating characteristic(ROC)curve was utilized to assess the differentiation and accuracy of the diagnostic methods.RESULTS Sixty-eight malignant nodules and 37 benign nodules were confirmed by surgical pathology or puncture biopsy.After enhancement by ultrasonography,the percentage of malignant nodules with low intensity,centripetal enhancement,inhomogeneous enhancement,blurred boundary of enhanced nodules,enlarged enhanced nodules,and irregular enhanced nodules was significantly higher than that of the benign group,while the percentage of circumferential enhancement was lower than that of the benign group(P<0.05).The overall compliance rate of ultrasonography scoring in diagnosing C-TI-RADS category 4 thyroid nodules was 83.81%(88/105),and when compared with the pathological gold standard,the Kappa value was 0.644.The ROC curve analysis showed that the sensitivity of ultrasonography scoring in diagnosing benign and malignant nodules was 84.51%,the specificity was 82.35%,the correctness index was 0.669,the negative likelihood ratio was 0.188,and the positive likelihood ratio was 4.789.The overall compliance rate of elastography score in diagnosing C-TI-RADS category 4 thyroid nodules was 85.71%(90/105),and when compared with the pathological gold standard,the Kappa value was 0.689.The ROC curve analysis revealed that the sensitivity of elastography score in diagnosing benign and malignant nodules was 88.24%,the specificity was 81.08%,the correctness index was 0.693,the negative likelihood ratio was 0.145,and the positive likelihood ratio was 4.664.Ultrasonography enhancement features,along with the combination of ultrasonography score and elastography score,had an AUC=0.922(0.876-0.968),with an accuracy of 92.91%,demonstrating a strong ability to identify truly malignant nodules versus benign nodules.CONCLUSION Ultrasonography combined with elastography scoring is valuable in the correction of C-TI-RADS category 4 nodules in the thyroid gland and helps to improve diagnostic accuracy.
