Objective To explore the feasibility and reference value of allogeneic lung transplantation and postoperative monitoring in miniature pigs for lung transplantation research. Methods Two miniature pigs (R1 and R2) underwent left lung allogeneic transplantation. Complement-dependent cytotoxicity tests and blood cross-matching were performed before surgery. The main operative times and partial pressure of arterial oxygen (PaO₂) after opening the pulmonary artery were recorded during surgery. Postoperatively, routine blood tests, biochemical blood indicators and inflammatory factors were detected, and pathological examinations of multiple organs were conducted. Results The complement-dependent cytotoxicity test showed that the survival rate of lymphocytes between donors and recipients was 42.5%-47.3%, and no agglutination reaction occurred in the cross-matching. The first warm ischemia times of D1 and D2 were 17 min and 10 min, respectively, and the cold ischemia times were 246 min and 216 min, respectively. Ultimately, R1 and R2 survived for 1.5 h and 104 h, respectively. Postoperatively, in R1, albumin (ALB) and globulin (GLB) decreased, and alanine aminotransferase increased; in R2, ALB, GLB and aspartate aminotransferase all increased. Urea nitrogen and serum creatinine increased in both recipients. Pathological results showed that in R1, the transplanted lung had partial consolidation with inflammatory cell infiltration, and multiple organs were congested and damaged. In R2, the transplanted lung had severe necrosis with fibrosis, and multiple organs had mild to moderate damage. The expression levels of interleukin-1β and interleukin-6 increased in the transplanted lungs. Conclusions The allogeneic lung transplantation model in miniature pigs may systematically evaluate immunological compatibility, intraoperative function and postoperative organ damage. The data obtained may provide technical references for subsequent lung transplantation research.

Kynurenine pathway (KP) is a major catabolic route of tryptophan, generating a series of bioactive metabolites including kynurenine, kynurenic acid (KA), quinolinic acid, and 3-hydroxykynurenine. Beyond its fundamental role in amino acid metabolism, KP exerts critical regulatory functions in neurodevelopment, synaptic plasticity, and immune modulation. Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition with onset in early childhood, characterized by persistent deficits in social communication and restricted, repetitive behaviors. Despite extensive research, the etiological mechanisms underlying ASD remain highly complex and incompletely understood, involving genetic, environmental, and immunological factors. Emerging clinical evidence has consistently revealed a significant imbalance in KP metabolites in individuals with ASD, often accompanied by altered ratios of neuroprotective versus neurotoxic byproducts. However, the primary drivers of this metabolic dysregulation and its causative contribution to ASD pathogenesis are not yet fully elucidated. In this review, we systematically review the enzymatic steps of KP and the principal physiological functions of its major metabolites, with particular emphasis on their dual roles in neuroprotection and neurotoxicity. We then analyze the potential pathogenic mechanisms through which KP dysfunction may contribute to ASD, focusing on two interconnected etiological dimensions. First, KP imbalance can promote oxidative stress, which in turn triggers chronic inflammatory responses via microglial activation and release of pro-inflammatory cytokines, thereby disrupting neuronal homeostasis. Second, aberrant KP metabolism affects neurotransmitter systems, particularly glutamatergic and dopaminergic signaling, leading to impaired neural circuit development and synaptic pruning. By integrating current findings on the KP-ASD association, this review offers a comprehensive etiological framework and a clinically relevant paradigm. Furthermore, we highlight that specific KP metabolites, such as the KA/quinolinic acid ratio, hold promise as peripheral biomarkers for early diagnosis and disease stratification. Finally, we discuss the therapeutic potential of targeting KP enzymes or receptors for personalized intervention strategies, while acknowledging the challenges in translating these findings into clinical practice.

Objective:To evaluate the efficacy and long-term outcomes of fludarabine, cyclophosphamide, and rituximab (FCR) in treatment-na?ve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) .Methods:Clinical data from 68 CLL/SLL patients treated with FCR at Jiangsu Province Hospital (August 2008–May 2021) were retrospectively analyzed to assess efficacy, safety, and survival outcomes.Results:Among 68 patients [46 males, 22 females; median age 55 (47, 60) years], 13.1% (8/61) had a complex karyotype, 32.3% (20/62) had immunoglobulin heavy variable region mutated (IGHV-M) type, 6.6% (4/61) had del (17p), and 14.8% (8/54) had del (11q). Patients received a median of 6 (4, 6) FCR cycles. The overall response rate was 88.2% (60/68), including 47.0% (32/68) complete remissions. Over a median follow-up of 82 (59, 98) months, 66.2% (45/68) experienced disease progression. Median progression-free survival was 56 (21, 123) months, while median overall survival was not reached. The 5- and 10-year PFS rates were 42.6% (95% CI: 31.9–56.8% ) and 28.7% (95% CI: 19.0–43.4% ), respectively. Poor PFS was associated with del (17p) ( HR=5.04, 95% CI: 1.72–14.74, P=0.003), del (11q) ( HR=5.27, 95% CI: 2.11–13.15, P<0.001), IGHV unmutated (IGHV-UM) ( HR=4.11, 95% CI: 1.72–9.79, P=0.001), complex karyotype (CK) ( HR=3.53, 95% CI: 1.58–7.85, P=0.002), β 2-microglobulin >3.5 mg/L ( HR=2.87, 95% CI: 1.37–6.01, P=0.005). In multivariate analysis, IGHV-UM remained an independent predictor of PFS ( HR=8.63, 95% CI: 1.09–68.40, P=0.042). Sixteen patients with IGHV-M and lacking del (17p) or CK had a median PFS of 123 (58,123) months and a 5-year PFS rate of 70.7% (95% CI: 49.7–99.1% ), reaching a plateau after 5 years with no recurrences by 10 years. Common grade 3–4 adverse events included hematologic toxicity (44.1%, 30/68), infection (36.7%, 25/68), and liver dysfunction (4.4%, 3/68). Among 25 patients receiving single-agent BTK inhibitors after FCR progression, median follow-up was 45 (26, 64) months; 36% (9/25) experienced disease progression, with a median PFS time of 55 (27, 55) months. Conclusion:First-line FCR provides durable long-term benefits for patients with IGHV-M CLL without del (17p) or CK.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the effects of Qingre Qudu Decoction for fumigation combined with three-gap drainage on wound healing and serum inflammatory factors in patients with acute perianal abscess.Methods:Randomized controlled trial was conducted. A total of 117 patients with acute perianal abscess in the hospital were enrolled as the observation objects between August 2022 and May 2024. According to random number table method, they were divided into observation group (59 cases) and control group (58 cases). Both groups received three-gap drainage therapy. On basis of three-gap drainage, control group was given potassium permanganate, while observation group was given Qingre Qudu Decoction for fumigation. All patients were treated for 14 d. The growth of granulation tissue and wound secretions before and after treatment was evaluated. VAS scale was used to evaluate the degree of incision pain, and Wexner score was used to assess incontinence; ELISA was used to detect serum activator A (ACTA), immunoturbidimetry was used to detect serum CRP, and radioimmunoassay was used to detect serum IL-6 levels. The occurrence of complications and abscess recurrence during treatment was recorded, and clinical efficacy was evaluated.Results:The total effective rate of the observation group was 96.61% (57/59), while that of the control group was 82.76% (48/58), with statistical significance ( χ2=6.10, P=0.014). After treatment, scores of granulation tissue growth and wound secretions in observation group, and scores of VAS and Wexner incontinence in observation group were lower than those in the control group ( t=9.66, 5.00, 7.98, 3.65, P<0.001), and wound healing time was shorter than that in control group ( t=8.41, P<0.001). After treatment, levels of serum ACTA, CRP and IL-6 in observation group were lower than those in control group ( t=15.30, 2.08, 19.34, P<0.01 or P<0.05). The incidence of postoperative complications in the observation group was 6.78% (4/59), while in the control group it was 27.59% (16/58), with statistical significance ( χ2=8.93, P=0.003). Conclusion:Qingre Qudu Decoction for fumigation combined with three-gap drainage can relieve postoperative incision pain, inhibit inflammatory response, accelerate the recovery of wound and promote the recovery of anal function and improve clinical efficacy.

Nursery services are a vital component of childcare for infants and toddlers.The quality and management of nursery services significantly impact the holistic development of infants and toddlers in terms of their physical,psychological,and social skills and capabilities.The first 1000 days in the life of an infant or toddler are a critical period that shapes their health status for their whole life,which highlights the need to prioritize health in childcare for infants and toddlers and to approach daily childcare services from a medical perspective.Based on the approach of integrating medical care and education,we innovatively explored and constructed a multidisciplinary patrol supervision model for childcare services,focusing on the PDCA cycle(Plan-Do-Check-Act cycle).We aim at establishing a multidisciplinary team of medical and nursing experts who provide evaluation and guidance for the institutional management,health management for infants and toddlers,disease prevention,and risk identification and screening of childcare services for infants and toddlers.This approach addresses the issue of the simplistic nature of the traditional patrol supervision involving only childcare physicians,improves service quality with high efficiency,meets the expectations of both childcare service providers and the families of infants and toddlers-the users of childcare services,enhances the effective implementation of childcare for infants and toddlers based on the integration of medical care and education,and improves the quality of a health-centered approach to childcare for infants and toddlers.

Objective To investigate the protective effects of secretomes released by three-dimensional cultured mesenchymal stem cells(MSCs)on neurons subjected to seawater immersion(SW)and stretch injury(SI),and to provide new insights into neuronal repair following SW combined with traumatic brain injury(TBI).Methods MSCs were cultured using the hanging drop method,and the conditioned medium(CM)containing MSCs secretomes was collected.A cellular model combining SW with SI was established using mouse hippocampal neuronal cells(HT22 cells).HT22 cells were randomly assigned to five groups:control,SI,SI+SW,SI+CM,and SI+SW+CM groups.Cell viability was assessed using the CCK-8 assay,apoptosis rate was measured by flow cytometry,cell migration ability was evaluated by scratch assay,and the expression levels of apoptosis-related proteins Bcl-2 and Bcl-2-associated protein(Bax),and ferroptosis-related proteins long-chain acyl-CoA synthetase 4(ACSL4)and cyclooxygenase-2(COX-2)were detected by Western blotting.Results Immersion in 15%seawater for 12 h significantly decreased HT22 cell viability(P<0.05).The CCK-8 assay indicated that cell viability in both the SI and SI+SW groups was significantly lower than that in control group after 12 h of treatment(P<0.05).Treatment with CM containing MSCs secretomes significantly increased cell viability in SI+CM group compared to SI group(P<0.0001),and in SI+SW+CM group compared to SI+SW group(P<0.001).Flow cytometry results revealed that the apoptosis rate in SI and SI+SW groups was significantly higher than that in control group(P<0.05 or P<0.001),while in SI+CM group was lower than that in SI group(P<0.05),and in SI+SW+CM group was lower than that in SI+SW group(P<0.05).Western blotting showed that compared to control group,SI and SI+SW groups exhibited reduced Bcl-2 expression level(P<0.01 or P<0.0001)and increased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.0001).Compared to SI group,the SI+CM group displayed increased Bcl-2 expression level(P<0.05)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.05).Compared to SI+SW group,SI+SW+CM group exhibited increased Bcl-2 expression level(P<0.01)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.001).Scratch assay results demonstrated that at both 12 h and 24 h,the cell migration rate in SI and SI+SW groups was significantly lower than that in control group(P<0.01 or P<0.0001),while the migration rate in SI+CM group was significantly higher than that in SI group(P<0.0001 or P<0.01),and the migration rate in SI+SW+CM group was significantly higher than that in SI+SW group(P<0.0001).Conclusion Secretomes derived from MSCs cultured using the hanging drop method can alleviate neuronal damage caused by SW and TBI,potentially offering a therapeutic approach for SW combined with TBI.
