Objective 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.Conclusion BYHWD attenuates vascular aging in rats by modulating macrophage M1 polarization and suppressing vascular inflammation via exosomal miR-590-5p-mediated downregulation of SLC8A3.

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.

Cryptogenic multifocal ulcerous stenosing enteritis（CMUSE） is a rare and difficult disease characte-rized by chronic recurrent intestinal obstruction and gastrointestinal bleeding caused by multiple ulcers and strictures of the small intestine. There is still a lack of mature and systematic guidance for the treatment of the disease. This paper reported a case of CMUSE mainly manifested as fatigue， abdominal distention， and edema of both lower limbs ， who is treated by integrated traditional Chinese and western medicine. In western medicine treatment， hormone and symptomatic treatment are mainly used. In traditional Chinese medicine treatment， the method of fortifying spleen and reinforcing healthy qi is taken as the basis； during the active stage of the disease， the method of moving qi and removing stagnation， clearing and removing dampness and heat， astringing and engendering flesh should be combined with， while during the remission stage， it is advised to unite with the method of diffusing lung and moving water， regulating and harmonizing zang-fu （脏腑） organs； simultaneously， replenishing qi and invigorating blood can be used throughout the treatment， and attach importance to the maintenance therapy of the traditional Chinese medicine immunomo-dulatory agent Tripterygium glycosides. After more than 2 years of treatment， the patient's clinical symptoms were significantly relieved， and all indicators basically restored to normal， having a stable condition.

Hepatosplenic candidiasis (HSC) is a rare type of candidiasis that can occur in patients with hematologic malignancies, hematopoietic stem cell transplantation. At present, there is still a lack of studies on HSC in patients with hematologic disorders. Based on The Chinese Guidelines for the Diagnosis and Treatment of Invasive Fungal Disease in Patients with Hematological Disorders and Cancers (the 6th revision), We retrospectively analyzed the clinical characteristics and prognosis of patients with HSC treated in Peking University Institute of Hematology from 2008 to 2022. Finally, eighteen patients were included, with 1 (5.6%) proven, 2 (11.1%) probable, and 15 (83.3%) possible HSC. Among them, 3 (16.7%) patients occurred after haploid hematopoietic stem cell transplantation and 15 (83.3%) patients occurred after chemotherapy. 6 (33.3%) patients had positive blood cultures, including 4 cases of Candida tropicalis and 2 cases of Candida albicans. At 4 weeks of antifungal therapy, 10 (58.8%) patients achieved partial response (PR), At 8 weeks, 1 (6.3%) patients achieved complete response and 10 (62.5%) patients achieved PR. At 6 months after diagnosis, 3 (16.7%) patients died of hematopoietic recurrence, and none of them died of HSC. As a rare fungal infection disease, HSC has a low positive rate of microbiological and histological examinations, a persistent treat cycle, and has difficulty in remission, reminding us of the need for vigilance in patients with hematopoietic disorders and persistent fever.

Objective This study aims to systematically evaluate the experiences of patients with hematologic neoplasm undergoing chimeric antigen receptor T-cell(CAR-T)therapy and nursing care,and to provide a reference basis for healthcare providers to develop personalized intervention strategies.Methods PubMed,Web of Science,Embase,CINAHL,Cochrane Library,PsycINFO,Scopus,Australia Joanna Briggs Institute(JBI)EBP Database,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP Database,and China Biology Medicine(CBM)Database were systematically searched for qualitative studies on the experiences of patients with hematologic neoplasm undergoing CAR-T therapy and nursing care.The search period extended up to September 2023.The quality of the literature was reviewed according to the JBI Qualitative Assessment and Review Instrument,and a pooled analysis was applied to integrate the results.Results A total of 15 studies were included,generating 76 findings,which were then organized into 8 categories,resulting in 3 integrated findings.(1)Patients experienced conflicting emotions,with expectations often at odds with reality,leading to emotional fluctuations:expectations about treatment were entangled with concerns about risks;emotions fluctuated with expectations and actual experiences.(2)Patients experienced physical and social functional impairments,but as the disease eased,normal functioning recovered:rapid decline and improvement in physical functions;loss and recovery of social functions.(3)Patients desired access to professional guidance and psychosocial support.Conclusion Patients undergoing CAR-T therapy often contend with emotional conflicts.Changes in physical and social functions after the completion of treatment result in needs for seeking comprehensive medical and nursing support.It is recommended that healthcare providers conduct dynamic assessments and interventions regarding patients'emotional states before treatment,focus on early identification and management of adverse reactions after treatment,and offer continuous nursing services after discharge to enhance patients'confidence in participating in CAR-T therapy and improve their overall quality of life.

Objective To analyze result of the external quality assessment for laboratories of toxicological pathology diagnosis in organizations in China. Methods A total of 86 organizations that participated in the 2020-2021 external quality assessment in laboratory of toxicological pathology diagnosis (hereinafter referred to as "reference units") were selected as research subjects using convenient sampling method, and the assessment results were analyzed. Results The median of total score was 92, and the 0-100 percentiles were 64-100 in these 86 reference units. Among these reference units, 76 were rated as excellent, 10 as qualified, with the excellent and the qualified rate of 88.4% and 11.6%, respectively. No reference unit was rated as unqualified. The rates of excellence of the reference units in public health institutions, pharmaceutical research institutions, drug safety evaluation centers and testing companies were 95.7%, 84.2%, 85.7% and 86.7%, and the qualified rates were 4.3%, 15.8%, 14.3% and 13.3%, respectively. The distribution of excellence and qualification among the four types of reference units showed no statistical difference (P>0.05). The distribution of sample scores according to the three grades of poor, good, and excellent were 4.9%, 20.7%, and 74.5% in public health institutions, 8.6%, 23.7%, and 67.8% in pharmaceutical research institutions, 12.5%, 25.0%, and 62.5% in drug safety evaluation centers, and 5.4%, 17.5%, and 77.1% in testing companies. The proportion of excellence unit in public health institutions was higher than that in pharmaceutical research institutions (P<0.05). Conclusion The overall toxicological pathology diagnostic capabilities in China are good, and various types of reference units demonstrate comparable technical capabilities. However, there is a need for standardization of diagnostic terminology.
