Objective: To explore the correlation between the composition of bone marrow lymphocyte subsets and the clinical attributes observed in de novo AML patients, as well as their influence on prognosis. Methods: A detailed study was carried out on a cohort of 191 de novo acute myeloid leukemia patients who were admitted to our medical center between October 2022 and September 2024. In addition, a group of 24 patients with iron deficiency anemia individuals was carefully chosen as the control cohort. The proportions of lymphocyte subsets within the bone marrow of de novo AML patients were analyzed. Furthermore, an in-depth analysis was performed to investigate the association between the expression levels of these subsets in de novo AML patients and their clinical attributes, as well as their prognostic implications. Results: The proportion of CD19 and CD56 lymphocytes within the bone marrow of de novo AML patients significantly diminished compared to the control cohort (8.5% vs 13.2% P<0.05, and 15.5% vs 18.0%, P<0.05). Conversely, no significant discrepancies were observed in the CD3 , CD3 CD4 , and CD3 CD8 lymphocyte percentages between the AML patients and control group (71.7% vs 72.1%, 32.5% vs 33.7% and 32.8% vs 35.7%, P>0.05). When analyzing the relationships between lymphocyte subsets within the bone marrow of de novo patients and their respective clinical characteristics, patients aged 60 years and above exhibited diminished percentages of CD3 CD8 lymphocytes in the bone marrow compared to their younger counterparts (31.6% vs 34.1%, P<0.05), while the CD56 lymphocyte subsets demonstrated an increased prevalence (17.2% vs 14.4%, P<0.05). Furthermore, patients with leukocytosis (WBC≥100×10 /L) presented lower levels of CD3 and CD3 CD4 lymphocytes in the bone marrow compared with those without it (65.3% vs 72.9% P<0.05, and 28.9% vs 33.2%, P<0.05), respectively. The AML1-ETO fusion gene-positive cohort exhibited a higher prevalence of CD3 CD8 lymphocytes in the bone marrow than in the negative group (38.2% vs 32.3%, P<0.05), whereas the FLT3-ITD mutation-positive group presented a decreased prevalence of CD56 lymphocytes compared with the negative group (12.4% vs 16.8%, P<0.05). In addition, the NPM1 mutation-positive group demonstrated lower levels of CD3 CD8 lymphocytes in the bone marrow than in the negative group (29.1% vs 33.3%, P<0.05). Variables such as tumor protein p53(TP53) mutation positive, the absence of hematopoietic stem cell transplantation, and CD3 CD4 lymphocyte proportions below 25% were identified as independent adverse prognostic indicators for AML patients (P<0.05). Conclusion: The pathogenesis of AML is closely associated with an imbalance in bone marrow lymphocyte subsets. The FLT3-ITD mutation potentially contributes to the dysregulation of CD56 lymphocyte subset expression. The AML1-ETO fusion gene and NPM1 mutation are implicated in the abnormal expression of CD3 CD8 lymphocytes within the bone marrow. Moreover, the percentage of CD3 CD4 lymphocytes in the bone marrow serves as a prognostic factor for de novo AML patients.

OBJECTIVES: To investigate the mechanism underlying the inhibitory effect of Buyang Huanwu Decoction (BYHWD) on vascular aging. METHODS: Eighteen male SD rats were randomized into young group, intraperitoneal D-galactose injection-induced aging group, and BYHWD gavage group. The changes in pulse wave velocity (PWV), vascular SA-β-gal activity, and expressions of p16, p21 and SA‑β‑gal of the rats were examined. Serum exosomes were isolated from the rats, and after characterization using NTA and TEM and for surface markers and vascular cell markers, were examined for miR-590-5p expression using qRT-PCR. The M1/M2 macrophage ratio and cytokine levels were evaluated using immunofluorescence staining and qRT-PCR. Bioinformatics analysis and dual-luciferase reporter assays were carried out to predict the potential target genes of miR-590-5p and validate its targeting relationship with SLC8A3, whose expressions were detected in the vascular tissues of the rats by Western blotting. RESULTS: Compared with the young rats, the aging rats exhibited significantly increased PWV in the abdominal aorta with elevated vascular expressions of p16, p21 and SA-β-gal, which were all reversed by BYHWD treatment. The isolated serum exosomes were positive for CD63, CD81, CD31 and SM-22, and the exosomes from aging rats showed significantly downregulated expression of miR-590-5p, which was upregulated after BYHWD treatment. The aging rat vessels showed an increased M1/M2 macrophage ratio with elevated M1-specific cytokines and reduced M2-specific cytokines, and BYHWD treatment effectively inhibited M1 polarization of the macrophages. Pearson analysis revealed a negative correlation between exosomal miR-590-5p upregulation and the M1/M2 ratio. Bioinformatics analysis and dual-luciferase assays confirmed that miR-590-5p targets SLC8A3. Western blotting demonstrated increased SLC8A3 expression in aging rat vessels, which was downregulated after BYHWD treatment. CONCLUSIONS BYHWD attenuates vascular aging in rats by modulating macrophage M1 polarization and suppressing vascular inflammation via exosomal miR-590-5p-mediated downregulation of SLC8A3.

Surgery is an important treatment for the anterior mediastinal disease. With the rapid development of minimally invasive techniques, complete resection of the lesion in most patients with thymic disease can be achieved through thoracoscopic surgery. Practice has proved that the three-port resection of anterior mediastinal thymus disease via the subxiphoid approach is an ideal surgical method for the treatment of anterior mediastinal thymic tumors at present, which has strong popularization and popularity and can benefit the patients. The procedure focuses primarily on the anterior and upper mediastinum and can thoroughly expose the anatomy of the mediastinum and both sides, with minimal intraoperative bleeding, high safety, minimal trauma and postoperative pain, and a short hospital stay. It has clear advantages over conventional thoracic open-heart surgery and transversal resection. However, the surgical approach and field of view, and intraoperative precautions of this procedure are completely different from those of previous thoracoscopic procedures, and from the subxiphoid single-port approach adopted by other centers. Based on 10 years of surgical experience at our center, a modular mode of surgical operation has been developed and its procedure has been standardized. This paper will share and discuss relevant operational points and experiences.

Objective:To study the life characteristics and related risk factors of patients with depression in Shandong Province.Methods:Based on the 2015 mental epidemiological survey database in Shandong Province,a total of 832 patients with depression,807 high-risk individuals with depression,and 819 low-risk individuals were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)and the Structured Clinical Interview for DSM-Ⅳ-TR Axis I Disorders,Research Version(SCID-I/P).In 2020,SCID-I/P was used for re diagnosis,and the General Health Questionnaire(GHQ-12),Simple Quality of Life question-naire,Pittsburgh sleep quality index(PSQI),Childhood Trauma Questionnaire(CTQ),Social Support Rating Scale(SSRS),Global Pain Scale(GPS),Montreal Cognitive Assessment(MoCA),Simplified Coping Style Question-naire(SCSQ)were used for evaluation.Compare changes in the quality of life of depression patients and construct a risk factor model.Results:Patients with depression had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in the high-and low-risk groups,those in remission of depression had higher scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in non-re-mission,and those with new-onset disorder in the high-and low-risk groups had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those with no-onset disorder(Ps＜0.001).Depres-sion diagnosis and PSQI scale scores at baseline negatively predicted at retest after 5 years(β=-0.06,-0.15),while coping style tendencies at baseline positively predicted(β=0.06).The simple quality of life questionnaire at baseline negatively predicted depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,and PSQI scale scores at retest after 5 years(β=-0.11,-0.17,-0.09),while the simple quality of life question-naire at baseline positively predicted coping style tendencies at retest after 5 years(β=0.13).Depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,PSQI scale scores at retest after 5 years,coping style tendencies at retest after 5 years,SSRS scale scores,CTQ scale scores,GPS scale scores,and the simple quality of life questionnaire at baseline all influenced the simple quality of life questionnaire at retest after 5 years through ei-ther direct or indirect pathways.Conclusion:It suggest that the quality of life is lower in patients with depression than in the general population.Depression diagnosis,sleep,mental health,pain,social support,childhood trauma and coping are direct and indirect risk factors affecting life.

New daily persistent headache(NDPH)is a kind of persistent headache that patients can i-dentify the exact date of the sudden onset.It is one of the rare primary headaches difficult to be cured and may lead to disability,seriously affecting the daily life and work.The exact pathogenesis of NDPH remains unclear,which makes the treatment difficult.Here we report a case of refractory NDPH treated by intravenous injection of esketamine at a sub-anesthetic dose.

The typical manifestations of primary aldosteronism (PA) are hypertension with or without hypokalemia, high aldosterone, and low renal level. However, PA with normal blood pressure is rare in clinical practice. This article reported the diagnosis and treatment of a patient with subclinical PA, admitted for "adrenal accidental tumor" with normal blood pressure and serum potassium. We summarized and analyzed the clinical characteristics and treatment strategies, in order to provide some reference for clinicians.

Objective:To explore the factors that affect the participation of elderly care nurses in home-based elderly care services, in order to provide reference for the targeted improvement of human problems in home-based elderly care services.Methods:The phenomenological research method of qualitative research was used to conduct semi-structured in-depth interviews, on-site recordings and transcripts with 14 nurses in the geriatrics department of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical College from September to October, 2021. The collected data were analyzed and the theme was refined by using the 7-step analysis method of Colaizzi phenomenology.Results:Through sorting and analysis, four themes and six sub themes were extracted as follows: language behavior factors including environmental discomfort and differences in living habits, freedom was limited; psychological and emotional factors including high psychological pressure and loneliness, not respected; career development factors; social security factors including the definition of work scope is unclear, the division of responsibility for the accident was unclear and the protection of relevant rights and interests was insufficient.Conclusions:The intention of elderly care nurses to participate in home-based elderly care services is affected by many factors. These factors need to be accurately identified and targeted support measures should be taken to improve their enthusiasm to participate in home-based elderly care services and improve the human problems in home-based elderly care services.

Objective: To investigate the prevalence of diabetes among individuals at high risk of diabetes in Baoshan District, Shanghai Municipality, so as to provide insights into community-based diabetes management. Methods: Permanent residents at ages of 35 years and older were sampled from Baoshan District using a multistage stratified cluster sampling method, and residents at a high risk of diabetes were screened using the Form for Risk Assessment of Diabetes among Community Residents in Shanghai Municipality. Participants' demographics, disease history and history of medication were collected using questionnaire surveys, and height, body weight, waist circumference, hip circumference, and blood pressure were measured. Diabetes was screened using fasting blood glucose and glucose tolerance test. The factors affecting the development of diabetes were identified among high-risk residents for diabetes using a multivariable logistic regression model. Results: A total of 3 107 residents at a high risk for diabetes were enrolled, including 1 165 men (37.50%) and 1 942 women (62.50%) with a mean age of (63.58±9.77) years. The prevalence of diabetes was 21.69% among the study subjects, and multivariable logistic regression analysis showed that men (OR=1.689, 95%CI: 1.357-2.104), age (40 years-, OR=4.833, 95%CI: 1.036-22.553; 50 years-, OR=2.627, 95%CI: 1.432-4.819; 60 years-, OR=1.551, 95%CI: 1.119-2.150; 70 years and older, OR=1.579, 95%CI: 1.232-2.025); high school/technical secondary school (OR=2.677, 95%CI: 1.636-4.380), overweight/obesity (OR=1.891, 95%CI: 1.447-2.472), hypertension (OR=1.306, 95%CI: 1.049-1.626), dyslipidemia (OR=1.428, 95%CI: 1.114-1.831), history of impaired glucose regulation (OR=15.161, 95%CI: 11.827-19.434) and family history of type 2 diabetes mellitus (OR=2.092, 95%CI: 1.619-2.704) caused an increased risk of diabetes among residents at a high risk diabetes. Conclusions The prevalence of diabetes was 21.69% among high-risk populations of diabetes in Baoshan District. Gender, age, educational level, overweight/obesity, hypertension, dyslipidemia, history of impaired glucose regulation and family history of type 2 diabetes mellitus are factors affecting the development of diabetes among high-risk populations.

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.
