A 62-year-old male, was admitted to the hospital, with a chief complaint of fever lasting over 10 days and leukopenia and thrombocytopenia for 2 days. Ten days prior to admission, the patient experienced intermittent fever without obvious incentive factors. The breath sounds in both lungs were coarse, without accompanying dry or moist rales. Color Doppler Ultrasound indicated mild splenomegaly and multiple lymphadenectasis in the bilateral cervical, axillary, and inguinal regions. Morphological examination of bone marrow cells demonstrated abnormally large blasts, with some of the nuclei being rather irregular and cytoplasmic vacuoles. Immunophenotyping results identified this group of blast cells as immature monocytes. Karyotype analysis of chromosomes showed clonal abnormalities, with 19 out of 20 cells exhibiting near-tetraploid karyotypes, including complex karyotypic abnormalities involving chromosome17.Targeted next-generation sequencing (NGS) detected gene mutations associated with hematological malignancies that have definite or potential clinical significance,including TP53, SRSF2, STAG2, and ARID2, with variant allele frequencies (VAF) of 63.10%, 30.30%, 0.80%, and 0.60%, respectively. Integrating laboratory findings, the diagnosis was diagnosed as AML-M5 at high-risk. After receiving chemotherapy with the regimen of azacitidine combined with venetoclax, the patient passed away more than 20 days later.

Objective To investigate the correlations of serum stromal cell-derived factor-1(SDF-1),chemokine receptor 7(CXCR7)and vascular density in the optic disc area with clinical stages in patients with normal-tension glaucoma(NTG).Methods A total of 157 patients with NTG were included in the NTG group and divided into stage Ⅰ group(n=29),stage Ⅱ group(n=88),and stage Ⅲ group(n=40)based on different clinical stages;additionally,56 healthy individuals with physical examinations in the same period were selected as control group.Serum SDF-1 and CXCR7 levels were compared between the NTG group and the control group;changes in vascular den-sity in the optic disc area among patients with different clinical stages were analyzed;the multivariate Logistic regression analysis was conducted to explore the risk factors for NTG.Results Compared with the control group,the NTG group had significantly increased serum levels of SDF-1 and CXCR7(P＜0.05).Compared with the control group,patients in the NTG group showed significantly decreased densities of large vessels,capillaries,and the entire area,as well as significantly increased density of avascular areas(P＜0.05).The densities of capillaries and the entire area were significantly lower in the stage Ⅱ group and stage Ⅲ group than the stage Ⅰ group,while the density of avascu-lar areas was significantly higher(P＜0.05).The densities of large vessels(r=-0.503,P=0.006),capillaries(r=-0.546,P＜0.001),and the entire area(r=-0.553,P＜0.001)were negatively significantly correlated with clinical stages,while the density of avascular area was positively significantly correlated with clinical stages(r=0.521,P=0.002).The proportions of patients with hypertension,history of alcohol consumption,family history of glaucoma,and high ser-um levels of SDF-1 and CXCR7 in the NTG group were significantly higher than those in the control group(P＜0.05).Multivariate Logistic regression analysis revealed that hypertension,family histo-ry of glaucoma,history of alcohol consumption,and high serum levels of SDF-1 and CXCR7 were risk factors for NTG(P＜0.05).Conclusion Patients with NTG have significantly increased ser-um levels of SDF-1 and CXCR7.The densities of large vessels,capillaries,and the entire area are negatively correlated with clinical stages,while the density of avascular areas is positively correlated with clinical stages.Serum levels of SDF-1 and CXCR7 can serve as effective reference indicators for the diagnosis and clinical staging of NTG.

Objective:To explore the status quo and influencing factors of self-management behavior in high-risk stroke patients, so as to provide a basis for improving their self-management behavior.Methods:From March to June 2023, convenience sampling was used to select 395 high-risk stroke patients admitted to the First Affiliated Hospital of Naval Medical University as the study subject. A survey was conducted on patients using the General Information Questionnaire, Self-management Behavior Scale for High-risk Stroke Patients, and Cerebral Apoplexy Knowledge Questionnaire. Pearson correlation was used to analyze the correlation between self-management behavior and stroke knowledge. A total of 395 questionnaires were distributed, and unqualified questionnaires (such as regular or repetitive responses, conflicting options before and after) were excluded. Finally, 387 valid questionnaires were collected, with an effective response rate of 97.97%.Results:The score of the Self-management Behavior Scale for High-risk Stroke Patients for 387 high-risk stroke patients was (137.60±25.47), with a score indicator of 62.53%, which was at a moderate level. The score of the Cerebral Apoplexy Knowledge Questionnaire was (19.26±10.19), which was at a low level. The random forest algorithm showed that the importance order of influencing factors was stroke knowledge, number of ways to obtain health information, educational level, number of risk factors, frequency of physical examinations, medical insurance, age, work situation, and gender. The Lasso regression indicated that there were four influencing factors corresponding to the minimum error. The top four factors in importance were included in multiple linear regression, and the results showed that educational level, number of risk factors, number of ways to obtain health information, and stroke knowledge were the influencing factors of self-management behavior in high-risk stroke patients ( P<0.05) . Conclusions:The self-management behavior of high-risk stroke patients was at a moderate level. Medical and nursing staff should strengthen stroke knowledge education, provide personalized education for different risk factors, and improve the self-management of the target population to reduce the incidence of stroke.

Objective:To explore the mediating effect of coping style on disease perception and pre-hospital delayed behavioral intention in patients with acute ischemic stroke.Methods:This study was a cross-sectional study. From February to July 2023, convenience sampling was used to select 205 patients with acute ischemic stroke admitted to the First Affiliated Hospital of Naval Medical University as the study subject. The survey was conducted using the General Information Questionnaire, Stroke Pre-Hospital Delay Behavior Intention, Brief Illness Perception Questionnaire, and Simplified Coping Style Questionnaire.Results:205 questionnaires were filled out, 195 valid questionnaires, and the validity rate of the questionnaire was 95.1%. The Stroke Pre-Hospital Delay Behavior Intention score of patients with acute ischemic stroke was (63.61±16.12). Pre-hospital delayed behavioral intention in patients with acute ischemic stroke was positively correlated with disease perception and negative coping ( r=0.360, 0.266; P<0.01), and negatively correlated with positive coping ( r=-0.279, P<0.01). The mediating effects of positive and negative coping on disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients were 0.111 and 0.097, respectively, accounting for 26.89% and 23.49% of the total effect. Conclusions:There is a partial mediating effect of coping strategies between disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients. In the process of stroke management, medical and nursing staff can reduce pre-hospital delayed behavioral intentions by improving disease cognition and coping style.

A retrospective analysis was made on the clinical data of a child with Turnpenny-Fry syndrome who was treated in the Epilepsy Center of Kunming Children′s Hospital in January 2023 for developmental retardation and epileptic spasm.The child, a 1-year-and-4-month-old boy, had developmental retardation since birth and developed epileptic spasm at the age of 5 months.Physical examination and auxiliary examination showed distinct facial features, heart, bone and other developmental malformations.Electroencephalogram indicated hypsarrhythmia and epileptic spasm.The genetic test suggested the presence of c. 194C>T (p.Pro65Leu), a new heterozygous mutation in PCGF2 gene.The seizures were completely controlled with anti-seizure drugs.This child is the only case reported with infantile epileptic spasm as the main manifestation so far, expanding the understanding of the phenotype of the disease.

AIM: To analyze and compare the efficacy of binocular visual perception training and suspended vision trainer in postoperative rehabilitation of strabismus.METHODS: A total of 96 children who received surgical treatment from July 2022 to September 2023 were included in the study subjects, and they were group A(n=32), group B(n=32)and group C(n=32). After operation, binocular visual training, visual perception training and suspension vision trainer were used to compare the efficacy among groups.RESULTS: The changes of simultaneous visual function, fusion visual function, stereoscopic visual function, perceptual eye position(horizontal and vertical)and CIXTQ of the three groups of children were observed before training and at 3 mo after training, and the study found that the simultaneous visual function recovered differently at 3 mo after training, with the best recovery in the group B(all P<0.05); there were no significant differences in fusion visual function of the groups A and B(P>0.05), but there were statistical significance in fusion visual function among the three groups(all P<0.05); and there were no significant differences in recovery rate of stereoscopic visual function among the three groups(P>0.05). The improvement of perceptual eye position of the group B, either horizontally or vertically, was better than that of both the group A and group C(all P<0.05).CONCLUSION: Visual perception training has a higher value in the simultaneous visual function, fusion function, stereoscopic visual function, perceptual eye position and quality of life in children with strabismus.
