OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease （ASCVD） following percutaneous coronary intervention （PCI）. METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1， 2023 and December 31， 2024. According to the lipid-lowering regimen， the patients were categorized into evolocumab group （ n ＝86） and probucol group （ n ＝70）. Changes in lipid parameters [total cholesterol （TC）， low-density lipoprot ein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， triglycerides， lipoprotein （a）， and lipid goal achievement rate ] ， inflammatory markers [interleukin-6 （IL-6） and C-reactive protein （CRP） ] ， and cardiac function indices （left ventricular ejection fraction， left ventricular end-systolic diameter， left ventricular end-diastolic diameter， and N-terminal pro-B-type natriuretic peptide） were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment， including acute myocardial infarction， in-stent restenosis， acute heart failure， cerebral hemorrhage， and stroke， was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline （ P ＞0.05）. After 6 months of treatment， both groups demonstrated significant improvements in lipid profiles （except HDL-C） and inflammatory markers compared to those at baseline （ P ＜0.05）. The evolocumab group exhibited greater reductions in TC， LDL-C， IL-6， and CRP， along with a higher lipid target achievement rate， compared with the probucol group （ P ＜0.05）. There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups， nor in the incidence of adverse events during the treatment （ P ＞0.05）. CONCLUSIONS For ultra-high-risk ASCVD patients after PCI， both of the above treatment options are associated with improvements in blood lipid and inflammatory response， with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC， LDL-C and inflammatory markers reduction and lipid target achievement， compared to probucol.

Autoimmune hepatitis （AIH） is a chronic inflammatory liver disease mediated by T lymphocytes， and it can progress to liver cirrhosis or even liver failure without timely intervention. As a natural flavonoid compound， naringenin （NAR） shows a potential value in the prevention and treatment of AIH through multiple mechanisms such as remodeling immune homeostasis， targeted inhibition of inflammatory pathways， antioxidation， regulating hepatocyte metabolism and apoptosis， improving mitochondrial function， and regulating intestinal flora. However， the clinical translation and application of NAR is limited by issues such as low bioavailability and insufficient efficiency of liver-targeted delivery. This article systematically reviews the mechanism of action of NAR in the prevention and treatment of AIH， explores the potential signaling pathways involved in this process， and analyzes existing challenges in its translation and application and future research directions， so as to provide a reference for further research on NAR and its application in the prevention and treatment of AIH.

Objective:To construct a frailty risk prediction model for elderly patients with CHD based on machine learning, to address the limitations of existing tools and provide evidence-based support for clinical practice.Methods:A retrospective study was conducted on elderly CHD patients hospitalized at the Heart Center of the First Affiliated Hospital of Henan University of Chinese Medicine from September 2023 to March 2024. Meta-analysis and expert meetings were used to identify the risk factors for frailty in elderly CHD patients. Three machine learning algorithms, Logistic Regression, Random Forest, and Support Vector Machine, were used to construct predictive models using R 4.3.1 software. The predictive performance of the models was evaluated using sensitivity, specificity, accuracy, and the area under the receiver operating characteristic curve (AUC).Results:A total of 490 elderly CHD patients were included, with 267 males and 223 females, and an age of (71.02 ± 7.73) years. Among them, 160 patients (32.7%) developed frailty. Of the constructed models, the Random Forest model demonstrated the best predictive performance, with an accuracy of 0.703, recall of 0.629, and F1 score of 0.741, while the AUC was 0.811 (95% CI 0.762-0.850). Conclusions:The Random Forest model exhibited good predictive performance in assessing frailty risk in elderly CHD patients, with high accuracy and reliability. Future external validation studies can further assess its applicability and stability in different populations.

Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objective:To identify the pathogenic gene in a family with cone-rod dystrophy (CRD).Methods:A pedigree study was conducted.Clinical data were collected from three generations of six people from a family with CRD who visited Henan Eye Hospital in December 2019, including one patient.After detailed collection of the patient's medical history, the proband and his family members underwent best-corrected visual acuity, slit-lamp microscope+ front-lens examination, optometry, non-mydriatic fundus photography, spectral-domain optical coherence tomography (SD-OCT), and full-field flash electroretinography (ff-ERG). Peripheral venous blood (5 ml) was collected from the proband, his parents and siblings, and the whole genome DNA was extracted.The proband's DNA was sequenced using whole exome sequencing.Hemizygous and potentially pathogenic mutations were verified by Sanger sequencing.Pathogenicity was assessed according to the American College of Medical Genetics and Genomics (ACMG) guidelines.Tools such as SpliceAI and dbscSNV were used to predict the impact of mutations on mRNA splicing.This study strictly followed the Declaration of Helsinki, and the study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[15]). All subjects and guardians of minor subjects signed informed consent forms.Results:The proband (Ⅲ: 1), a 5-year-old boy, presented with recessive nystagmus in both eyes and a best corrected visual acuity of 0.2.Color vision examination revealed red-green color blindness without night blindness.SD-OCT showed the presence of neuroepithelial structures in both eyes, but the interdigitation zone was blurred in both eyes.ff-ERG showed a slight decrease in rod function and a moderate-severe decrease in cone function in the right eye, and a slight decrease in cone and rod function in the left eye.Gene sequencing results showed that the proband had the hemizygous splice site variant c. 1911-3C>A of the CACNA1F gene on the X chromosome.Sanger sequencing showed that neither his mother nor his younger sister carried the variant, suggesting it was novel.This variant site was not recorded in the normal population database (PM2). Bioinformatics tools SpliceAI and dbscSNV consistently predicted that this variation affects on splicing.According to the ACMG guidelines, this variation is pathogenic. Conclusions:A novel variant c. 1911-3C>A in the CACNA1F gene was found in a family with CRD, and this variant may be a pathogenic variant site in this CRD family.This discovery expands the spectrum of pathogenic variations in CRD.

Objective:To analyze the clinical characteristics of pulmonary mucormycosis (PM) in children with leukemia, and explore its diagnosis and treatment strategies and prognosis.Methods:In this case-series study, the clinical data of 19 children who were diagnosed with leukemia complicated by PM at the First Affiliated Hospital of Zhengzhou University from January 2020 to June 2024 were retrospectively analyzed.Their gender, age, type of leukemia, clinical manifestations, chest CT findings, bronchoscopy results, etiology, treatment regimens, and prognosis were summarized.The patients were divided into a survival group and a death group.The clinical data were compared between the 2 groups.Categorical variables were compared using the Fisher′s exact test, and continuous variables were compared using the Wilcoxon rank-sum test.Results:A total of 19 children aged 2 to 17 years with leukemia complicated by PM were involved, including 9 boys and 10 girls, with most cases (15 cases) occurring in the autumn and winter.The median time from the first leukemia chemotherapy to infection with mucor was 1 month.Clinical manifestations mainly included fever (100%), cough (94.7%), hemoptysis (42.1%), and pneumothorax (21.1%).Chest CT findings primarily showed extensive lung consolidation (84.2%), pleural effusion (84.2%), pulmonary nodules (78.9%), halo signs (73.7%), cavitation (36.8%), crescent signs (26.3%), and reverse halo signs (21.1%).Fourteen children underwent bronchoscopy, which primarily revealed tracheal obstruction, pale or congested mucosa, mucosal edema, mucosal necrosis, bronchial stenosis, and bronchial cavitary fistulas.Mucor was detected using various methods including metagenomic next-generation sequencing (mNGS), cultures, and lung tissue microscopy.Patients were mainly treated with intravenous administration of Amphotericin B in different formulations combined with oral Posaconazole.Three patients also underwent surgical resection of the affected lung lobe in addition to medical treatment.After treatment, 14 patients had a good prognosis, while 5 patients died.The causes of death were massive hemoptysis in 2 cases, severe respiratory failure in 1 case, and treatment withdrawn due to critical condition in 2 cases.There were no statistically significant differences in age, gender, type of leukemia, whether to undergo bronchoscopy and surgery, time from the first chemotherapy to onset of infection, presence of comorbid infection, chest CT characteristics, and time to start treatment between survival and death groups(all P>0.05). Conclusions:There is no specificity in clinical manifestations of leukemia complicated by PM, which, however, still exhibits some characteristics.mNGS plays a crucial role in early diagnosis.Intravenous administration of Amphotericin B combined with oral Posaconazole and surgical intervention are an effective treatment regimen.

Objective:To investigate the predictive value of refeeding syndrome (RFS) and its influencing factors for 30-day intensive care unit (ICU) readmission in critically ill patients.Methods:A prospective cohort study was conducted. Critically ill patients admitted to the department of critical care medicine, department of respiratory and critical care medicine, and department of neurology at Tianjin Medical University General Hospital from January to April in 2025 were enrolled. Patients were assessed for RFS according to the American Society for Parenteral and Enteral Nutrition (ASPEN) criteria. General information within 24 hours of ICU admission was collected via the electronic medical record system. Treatment details and 30-day ICU readmission status were dynamically recorded. Participants were divided into readmission and non-readmission groups based on whether ICU readmission occurred within 30 days. Intergroup comparisons were performed to identify differences. Multivariate Logistic regression was used to analyze the relationship between RFS and its influencing factors with 30-day ICU readmission. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive performance of risk factors.Results:A total of 196 critically ill patients were enrolled, among whom 25 (12.76%) were readmitted to ICU within 30 days and 171 (87.24%) were not. Significant differences were observed in the readmission group compared with the non-readmission group, including significantly higher rates of nasogastric decompression, higher acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, a higher incidence of RFS, and a longer duration of nasogastric decompression. Multivariate Logistic regression analysis showed that RFS was an independent risk factor for 30-day ICU readmission [odds ratio ( OR) = 5.756, 95% confidence interval (95% CI) was 1.603-20.670, P = 0.007]. APACHEⅡ score showed a positive correlation trend with 30-day ICU readmission ( OR = 1.057, 95% CI was 0.991-1.127, P = 0.092). ROC curve analysis showed that the combined prediction model incorporating RFS and APACHEⅡ score had an area under the ROC curve (AUC) of 0.766 (95% CI was 0.668-0.864), with a sensitivity of 88.0% and a specificity of 62.0%, which was significantly superior to a single indicator (the AUC of RFS and APACHEⅡ score was 0.639 and 0.624, respectively). Conclusions:RFS significantly increases the risk of 30-day ICU readmission in critically ill patients. A combined model incorporating RFS and APACHEⅡ score demonstrates good predictive efficacy for 30-day ICU readmission in critically ill patients.

Objective:To analyze the characteristics of anonymous online dating and related factors of not being tested for HIV among men who have sex with men and to provide the basis for developing targeted HIV prevention strategies and intervention measures.Methods:Using a cross-sectional study design, respondents were recruited with the assistance of MSM social organizations from April to July 2023 in eight cities in Shandong Province. Snowball sampling, activity venues, and networks were employed, targeting a sample size of 400 people per city. A face-to-face questionnaire survey collected data on sociodemographic characteristics, drug use, sexual intercourse, and online informed dating. Blood samples were also collected for HIV and syphilis antibody testing.Results:In the past six months, 2 787 MSM sought homosexual partners through the Internet, and 78.26% (2 181/2 787) chose to make anonymous online dating. Before having homosexual sex with online sexual partners, 10.41% (290/2 787) of them did not ask each other about HIV infection status and 33.37% (930/2 787) of them not being tested for HIV. There were statistically significant differences in the distribution of age, marital status, household registration, education level, sexual orientation, ways to find male sexual partners, not asking online sexual partners about their HIV status before sexual intercourse, no mutual HIV testing with online sexual partners before sexual intercourse, and syphilis antibody between anonymous and non-anonymous online dating persons (all P<0.05). The results of multivariate logistic regression analysis showed that <25 years old (a OR=1.43, 95% CI: 1.15-1.77) and ≥35 years old age group (a OR=1.61, 95% CI: 1.29-2.01), people with no AIDS knowledge (a OR=2.37, 95% CI: 1.25-4.49), drug users (a OR=1.38, 95% CI: 1.17-1.63), online dating anonymous (a OR=2.19, 95% CI: 1.76-2.73), HIV antibody positive (a OR=3.61, 95% CI: 2.22-5.88) and no intervention services in the last 1 year (a OR=1.58, 95% CI: 1.05-2.38) were the related factors of MSM not being tested for HIV before having sexual intercourse through online dating. Conclusions:The phenomenon of anonymous online dating was common among MSM in Shandong Province, and the proportion of MSM not being tested for HIV before having sexual intercourse through anonymous online dating was relatively high. It is necessary to strengthen health publicity and promote informed dating in MSM.

Objective:To understand the related factors of new-type drugs use and high-risk behaviors in online-dating men who have sex with men (MSM) in Shandong Province, and provide evidence for the development of targeted HIV prevention and intervention strategies.Methods:A cross-sectional study was conducted from April to July 2023 in eight sentinel surveillance sites across cities in Shandong, recruiting MSM participants. Each city enrolled a sample of 400 individuals. Face-to-face questionnaire surveys were conducted to collect data on socio-demographic characteristics, drug use and sexual behaviors, risk perception, and online-dating practices of the MSM, and χ2 test was used to compare the differences between online-dating MSM who used new-type drugs and those who didn't use. Logistic regression model was used to analyze the related factors of group sex behavior and the lack of HIV detection before sexual behavior in the online-dating MSM. Statistical analysis was performed by using software SPSS 29.0. Results:A total of 3 235 MSM were surveyed, in whom 2 787 (86.15%) used online-dating platforms to find partners in the past six months. The majority were those who were aged 25-34 years (39.18%, 1 092/2 787), unmarried/divorced/widowed (71.51%, 1 993/2 787), had an education level of college or above (69.36%, 1 933/2 787), and primarily identified as homosexual gays (77.97%, 2 173/2 787), 37.78% (1 053/2 787) believed that they were at low risk for HIV infection and 10.88% (303/2 786) believed that using new-type drugs was less harmful and 57.59% (1 605/2 787) reported new-type drugs use. Multivariate logistic regression analysis indicated that MSM who used new-type drugs had higher risk for group sex in the past six months (a OR=1.31, 95% CI: 1.06-1.63) and sexual activity without pre-HIV testing (a OR=1.57, 95% CI:1.14-2.15) compared with those who didn't use new-type drugs.MSM who believed that the risk of using new-type drugs was general, higher and very high had higher risks for group sex in the past six months (a OR=1.54, 95% CI: 1.09-2.18) and sexual activity withou pre-HIV testing (a OR=2.02, 95% CI:1.34-3.05) compared with those who believed using new-type drugs was less harmful. Conclusions:The use of new-type drugs was relatively common in the online-dating MSM in Shandong, with widespread high-risk behaviors and poor awareness of risks to health. A gap between knowledge awareness and behavior exists. It is necessary to strengthen the health education and promotion of HIV informed dating practices in MSM.

Objective To investigate the expression level of centromere protein(CENP)Ⅰin lung adenocarcinoma cells,to study the effects of CENPⅠon the proliferation,invasion,migration,apoptosis,and epithelial-mesenchymal transition(EMT)of lung adenocarci-noma cells,and to explore the possible mechanisms related to its occurrence.Methods The expression of CENPⅠmRNA and protein in four types of lung adenocarcinoma cells and normal alveolar epithelial cells were detected by quantitative real-time polymerase chain reaction(RT-qPCR)and Western blotting.The expression of CENPⅠin H1650 cells was knocked down by the siRNA technique,The transfection efficiency was detected by RT-qPCR and Western blotting.The effects of knock-down CENPⅠon proliferation,cell cycle,apoptosis,invasion and migration of H1650 cells were detected by the cell counting kit-8 assay,the transwell assay,and flow cytometry.Western blotting was used to detect the expression of E-cadherin,N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,PI3K,AKT,mTOR,p-PI3K,p-AKT,and p-mTOR.Results After the knock-down of CENPⅠ,the proliferative ability of the H1650 cells significantly decreased,the number of apoptotic cells significantly decreased,and the cell invasion and migration abilities significantly decreased(P<0.01).E-cadherin expression was upregulated and N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,p-PI3K,p-AKT,and p-mTOR expres-sion were down-regulated in the CENTI group compared with the control group(P<0.05).The expression of p-PI3K,p-AKT,and p-mTOR in the si-CENPⅠ+IGF-1 group was upregulated compared to that in the si-CENPⅠgroup(P<0.05).Conclusion High expression of CENPⅠin lung adenocarcinoma cells promotes the proliferation,invasion,and migration of lung adenocarcinoma H1650 cells and EMT inhibits apoptosis,which may be related to the activation of the PI3K/AKT/mTOR signaling pathway.
