Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Male factors contribute to 50% of infertility cases, with 20%-30% of cases being solely attributed to male infertility. Helicase for meiosis 1 ( HFM1 ) plays a crucial role in ensuring proper crossover formation and synapsis of homologous chromosomes during meiosis, an essential process in gametogenesis. HFM1 gene mutations are associated with male infertility, particularly in cases of non-obstructive azoospermia and severe oligozoospermia. However, the effects of intracytoplasmic sperm injection (ICSI) in HFM1 -related infertility cases remain inadequately explored. This study identified novel biallelic HFM1 variants through whole-exome sequencing (WES) in a Chinese patient with severe oligozoospermia, which was confirmed by Sanger sequencing. The pathogenicity of these variants was assessed using real-time quantitative polymerase chain reaction (RT-qPCR) and immunoblotting, which revealed a significant reduction in HFM1 mRNA and protein levels in spermatozoa compared to those in a healthy control. Transmission electron microscopy revealed morphological abnormalities in sperm cells, including defects in the head and flagellum. Despite these abnormalities, ICSI treatment resulted in a favorable fertility outcome for the patient, indicating that assisted reproductive techniques (ART) can be effective in managing HFM1 -related male infertility. These findings offer valuable insights into the management of such cases.

OBJECTIVES: To investigate the mechanism of DDX17 for regulating proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) during the development of pulmonary hypertension (PH). METHODS: In murine PASMCs cultured under normoxic or hypoxic conditions, the effects of transfection with si-Ddx17 and insulin treatment, alone or in combination, on cell proliferation and migration were evaluated using Ki-67 immunofluorescence staining, scratch assay and Transwell assay. Western Blotting was performed to detect the changes in protein expression levels of DDX17, 4EBP1, S6, p-4EBP1, and p-S6. In a mouse model of PH induced by intraperitoneal injection of monocrotaline (MCT), the changes in pulmonary vasculature were examined using HE staining following tail vein injection of AD-Ddx17i. RESULTS: The PASMCs in hypoxic culture exhibited significantly enhanced cell proliferation and migration and protein expressions of p-4EBP1 and p-S6, and these changes were obviously reversed by transfection with si-Ddx17. Treatment with insulin significantly attenuated the effect of si-Ddx17 against hypoxic exposure-induced changes in PASMCs. In the mouse model of MCT-induced PH, transfection with AD-Ddx17i obviously alleviated pulmonary vascular stenosis and intimal hyperplasia. CONCLUSIONS The expression of DDX17 is elevated in hypoxia-induced PASMCs and PH mice, and silencing DDX17 significantly inhibits PASMC proliferation and migration in vitro and pulmonary vascular remodeling in PH mice by reducing mTORC1 activity.

Background and Aims:Chronic skin ulcers are a significant disease affecting patients'daily lives and psychological well-being.Abnormalities in the cells and extracellular matrix within the tissue may disrupt the balance of the microenvironment,hindering the normal skin repair process and leading to delayed healing of the ulcer.There is currently a lack of research on the mechanisms underlying the development of chronic ulcers and their diagnostic biomarkers.Single-cell sequencing,a newly developed high-throughput sequencing method in recent years,uses gene sequencing at the single-cell resolution to precisely reveal disease mechanisms and has been applied in various diseases.This study used single-cell transcriptome sequencing(scRNA-Seq)to investigate the cellular heterogeneity in chronic skin ulcer tissue to elucidate the potential molecular mechanisms behind delayed healing and provide new insights for clinical treatment.Methods:The scRNA-Seq technology was used to compare the differences in cell subpopulations and gene expression between chronic ulcer tissue and normal skin tissue.Single cells were sorted using a microfluidic platform,and cDNA libraries were constructed for subsequent differential gene analysis and functional enrichment analysis.Results:scRNA-Seq analysis revealed significant immune-metabolic remodeling features in chronic ulcer tissue:the number of B cells,monocytes,and macrophages in ulcer tissue increased by 2.1 to 3.5 times compared to the normal tissue control.This was accompanied by widespread activation of collagen synthesis genes(COL1A1/COL3A1)and synergistic suppression of immune regulators(e.g.,granzyme family GZMA/GZMB/H).Cross-cell subpopulation functional network analysis showed that hypoxia response mediated by the HIF-1 signaling pathway and PI3K/Akt pathway abnormalities formed a positive feedback loop,exacerbating the imbalance in the secretion of inflammatory factors(CXCL3/8,TGFBI)and compensatory upregulation of mitochondrial oxidative phosphorylation.Conclusion:Chronic skin ulcers exhibit significant differences in cellular heterogeneity and gene expression,suggesting that chronic ulcers are not simply tissue defects but a complex pathological process dominated by chronic inflammation and immune dysregulation.The coordinated dysregulation of multiple cell subpopulations in the ulcer microenvironment,along with persistent inflammatory responses and metabolic abnormalities,is interconnected through the HIF-1/TNF/MAPK pathway network.Downregulation of granzyme gene family members and abnormal histone modifications may contribute to immune clearance defects,providing a theoretical basis for developing novel therapies targeting epigenetic regulation or mitochondrial function.

Objective:To summarize the clinical manifestations, diagnosis and treatment of a family with hereditary sensory and autonomic neuropathy (HSAN) caused by the SPTLC1 gene variation and to review the literature. Methods:Case summary.The clinical manifestations, neuroelectrophysiology, genetic examination, treatment and follow-up of a family with autosomal dominant HSAN diagnosed at the Department of Neurology, Beijing Children′s Hospital in March 2024 were summarized.At the same time, related English and Chinese literatures were searched from CNKI, Wanfang and PubMed databases from their establishment to July 2024, with " serine palmitoyltransferase long-chain base subunits 1", " hereditary sensory and autonomic neuropathy", " SPTLC1" and " HSAN1" taken as key words.Results:The proband was a 11-year-and-2-month-old boy, who developed limited bending at the age of 7.The patient had ankle pain and knee bending during walking, and limited movement.He could neither jump on one foot nor bend down to pick up things from the ground, but there was no obvious sensory and autonomic nervous function abnormalities.His parents had no abnormal clinical manifestations.Neuroelectrophysiology showed peripheral nerve damage, and family whole exon sequencing revealed a maternal heterozygous missense variation of the SPTLC1 gene c.1015G>A, p.A339T(maternal origin, reported).Further maternal neuroelectrophysiology examination and sphingomyelin analysis confirmed the diagnosis of HSAN1A.The proband wore orthopedic insoles, and the proband and his mother took L-serine orally for 8 months.During the follow up, the proband reported slight improvement in muscle strength, and no adverse reactions were found.Two Chinese and thirteen English case reports on autosomal dominant HSAN caused by the SPTLC1 gene variation were retrieved.Twenty cases had complete clinical data.Therefore, a total of 22 cases, including the above-mentioned two patients, were analyzed.Except for patients whose age at diagnosis is unknown and who are deceased, the age at diagnosis ranged from 7 to 93 years.The 66.7%(14/21) cases were childhood-onset.The first clinical symptoms were mainly gait abnormalities, easy falls, sensory disorders and ulcers.Foot deformity, and autonomic neuropathy were detected in 53.3% (8/15), and 31.6% (6/19) cases, respectively, 15.8% (3/19) of the cases had amputation.Only 1 case was treated with L-serine, who showed partial relief of clinical symptoms, but electromyography was not significantly improved.Fifteen cases received neuroelectrophysiological testing, and 78.6%(11/14) of the patients showed sensory and motor neurogenic injuries.All the gene variations reported previously were missense mutations, and the high frequency variation was p. C133T/W. Conclusions:This study is helpful to improve the understanding of the clinical characteristics of HSAN1A caused by the SPTLC1 gene.Oral L-serine supplementation may benefit patients and gene detection promotes diagnosis confirmation and early treatment.

The evolution of acupuncture anesthesia (AA) has spanned six decades. Cardiothoracic surgery serves as a representative case study to illustrate this evolution. Reflecting on its historical development, the use of AA in cardiothoracic surgery has advanced from basic AA procedures in the 1960s to combined acupuncture and drug anesthesia techniques in the early 1980s. Since 2005, the innovative use of non-intubation AA combined anesthesia has been implemented extensively in cardiothoracic surgery. As the medical industry continues to evolve, the techniques applied in AA have expanded to encompass the entire perioperative period in cardiothoracic surgery, leading to the introduction of the concept of modern AA. The use of AA in cardiothoracic surgery exemplifies the ongoing advances and integration of traditional Chinese and Western medicine. Moving forward, it is imperative to enhance the theoretical framework of AA through the execution of rigorous multicenter clinical trials, to further strengthen the body of evidence supporting evidence-based medicine, and to finally explore the underlying mechanisms of AA.

OBJECTIVE: This study aimed to evaluate the association between susceptibility genes and non-alcoholic fatty liver disease (NAFLD) in children with obesity. METHODS: We conducted a two-step case-control study. Ninety-three participants were subjected to whole-exome sequencing (exploratory set). Differential genes identified in the small sample were validated in 1,022 participants using multiplex polymerase chain reaction and high-throughput sequencing (validation set). RESULTS: In the exploratory set, 14 genes from the NAFLD-associated pathways were identified. In the validation set, after adjusting for sex, age, and body mass index, ECI2 rs2326408 (dominant model: OR = 1.33, 95% CI: 1.02-1.72; additive model: OR = 1.22, 95% CI: 1.01-1.47), C6orf201 rs659305 (dominant model: OR = 1.30, 95% CI: 1.01-1.69; additive model: OR = 1.21, 95% CI: 1.00-1.45), CALML5 rs10904516 (pre-ad dominant model: OR = 1.36, 95% CI: 1.01-1.83; adjusted dominant model: OR = 1.40, 95% CI: 1.03-1.91; and pre-ad additive model: OR = 1.26, 95% CI: 1.04-1.66) polymorphisms were significantly associated with NAFLD in children with obesity ( P < 0.05). Interaction analysis revealed that the gene-gene interaction model of CALML5 rs10904516, COX11 rs17209882, and SCD5 rs3733228 was optional ( P < 0.05), demonstrating a negative interaction between the three genes. CONCLUSION In the Chinese population, the CALML5 rs10904516, C6orf201 rs659305, and ECI2 rs2326408 variants could be genetic markers for NAFLD susceptibility.

OBJECTIVE: To investigate the spatiotemporal patterns and socioeconomic factors influencing the incidence of tuberculosis (TB) in the Guangdong Province between 2010 and 2019. METHOD: Spatial and temporal variations in TB incidence were mapped using heat maps and hierarchical clustering. Socioenvironmental influencing factors were evaluated using a Bayesian spatiotemporal conditional autoregressive (ST-CAR) model. RESULTS: Annual incidence of TB in Guangdong decreased from 91.85/100,000 in 2010 to 53.06/100,000 in 2019. Spatial hotspots were found in northeastern Guangdong, particularly in Heyuan, Shanwei, and Shantou, while Shenzhen, Dongguan, and Foshan had the lowest rates in the Pearl River Delta. The ST-CAR model showed that the TB risk was lower with higher per capita Gross Domestic Product (GDP) [Relative Risk ( RR), 0.91; 95% Confidence Interval ( CI): 0.86-0.98], more the ratio of licensed physicians and physician ( RR, 0.94; 95% CI: 0.90-0.98), and higher per capita public expenditure ( RR, 0.94; 95% CI: 0.90-0.97), with a marginal effect of population density ( RR, 0.86; 95% CI: 0.86-1.00). CONCLUSION The incidence of TB in Guangdong varies spatially and temporally. Areas with poor economic conditions and insufficient healthcare resources are at an increased risk of TB infection. Strategies focusing on equitable health resource distribution and economic development are the key to TB control.

Aim To investigate the role of myotubula-rin related protein 7(MTMR7)in the pathogenesis of pulmonary hypertension manifested by pulmonary vas-cular intimal thickening,right ventricular hypertrophy,progressive right heart failure and dysfunction.Meth-ods A total of 40 healthy male C57BL/6J mice and Mtmr7-transgenic(Mtmr7-Tg)mice were divided into the control group,Mtmr7-Tg group,monocrotaline(MCT)group and MCT+Mtmr7-Tg group.Pulmonary artery acceleration time(PAT)and pulmonary artery ejection time(PET)of the pulmonary artery were measured by ultrasound.When the free wall of the right ventricle was separated,the right heart hypertro-phy index(RVHI)was calculated.Pulmonary artery remodeling was observed by immunostaining.Mouse pulmonary artery smooth muscle cells(PASMCs)were cultured in hypoxic environment to induce the prolifer-ation and migration.Results MTMR7 was expressed in pulmonary vessels.Compared to the wild-type mice,Mtmr7-Tg mice showed increased PAT/PET ratio(P＜0.05),reduced RVHI(P＜0.01)after MCT stimu-lus.PASMCs were transfected with adenovirus encond-ing Mtmr7 gene,which inhibited proliferation and mi-gration of PASMCs.After restoring the activity of ERK1/2 by chemerin-9,the proliferation and migra-tion ability of PASMCs was elevated.Conclusions MTMR7 can counteract the growth and mobility of mouse PASMCs induced by hypoxia,thereby comba-ting pulmonary arterial hypertension via reducing ERK1/2 phosphorylation.

Objective:To investigate the association between serum ferritin levels, erythrocyte parameters, and the risk of developing type 2 diabetes mellitus.Methods:A total of 11 408 subjects aged 40 to 70 years who underwent physical examinations at a hospital in Qingdao from 2014 to 2015 were enrolled in the study. Data were collected through questionnaires, physical examinations, and assessments of blood biochemical indices, serum ferritin, and related erythrocyte parameters. A multivariate logistic regression model was employed to analyze the relationship of serum ferritin and red cell parameters with type 2 diabetes mellitus, while a linear regression model was utilized to examine the association between serum ferritin, red cell parameters and fasting blood glucose levels.Results:The median ( Q1, Q3) age of the subjects was 51 (45, 58) years, with 55.3% (6 305) being male. The prevalence of type 2 diabetes in women was 5.9% (300/5 103), which was lower than that in men [13.0% (817/6 305)] ( P<0.001).After adjusting for age, sex, body mass index (BMI), smoking status, alcohol consumption, and family history of diabetes, serum ferritin levels were found to be positively associated with both type 2 diabetes and fasting blood glucose levels, with OR (95% CI) and β(95% CI) values of 1.70 (1.37, 2.11) and 0.002 (0.002, 0.003), respectively. Additionally, hemoglobin, red blood cell count, and hematocrit were positively correlated with type 2 diabetes and fasting blood glucose, with OR (95% CI) values of 1.72 (1.32, 2.24), 1.91 (1.51, 2.41), and 1.52 (1.17, 1.97), and β (95% CI) values of 0.008 (0.006, 0.011), 0.365 (0.286, 0.445), and 2.543 (1.564, 3.521), respectively. Conversely, mean erythrocyte volume was negatively associated with type 2 diabetes and fasting blood glucose, with OR (95% CI) and β (95% CI) values of 0.54 (0.45, 0.66) and -0.017 (-0.023, -0.011), respectively (all P values<0.001). Conclusion:The findings indicate that serum ferritin and related erythrocyte parameters are significantly correlated with the risk of type 2 diabetes mellitus and fasting blood glucose levels.
