Background. One-lung ventilation (OLV) during thoracic surgery may induce alveolar cell damage and release of proinflammatory mediators. The current trial was planned to evaluate effect of propofol versus isoflurane anesthesia on alveolar and systemic immune modulation during thoracic surgery. Methods. Fifty adult patients undergoing open thoracic surgery were randomly assigned to receive propofol (n = 25) or isoflurane (n = 25) anesthesia. The primary outcome measures included alveolar and plasma concentrations of interleukin-8(IL-8) and tumour necrosis factor-α (TNF-α), whereas secondary outcome measures were alveolar and plasma concentrations of malondialdehyde (MDA), superoxide dismutase (SOD), and changes in alveolar albumin concentrations and cell numbers. Results. Alveolar and plasma concentrations of IL-8 and TNF-α were significantly lower in the isoflurane group, whereas alveolar and plasma concentrations of MDA were significantly lower in the propofol group. Alveolar and plasma SOD levels increased significantly in the propofol group whereas they showed no significant change in the isoflurane group. Furthermore, the isoflurane group patients developed significantly lower alveolar albumin concentrations and cell numbers. Conclusion. Isoflurane decreased the inflammatory response associated with OLV during thoracic surgery and may be preferable over propofol in patients with expected high levels of proinflammatory cytokines like cancer patients.

Several techniques for the surgical correction of congenital supravalvular aortic stenosis have been devised. We describe the step-by-step surgical approach of a slide aortoplasty to correct localized supravalvular aortic stenosis in a 3-year-old child with Williams syndrome.

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.

This study evaluated the safety, effectiveness, and factors associated with the treatment of PC using a sandwiched bar and screw fixation system, first performed in Vietnam at the University Medical Center Ho Chi Minh City in 2016.
Methods: This retrospective cohort study was conducted from March 2016 to February 2023 in patients with PC and PC-mixed pectus excavatum (PE) deformities.

Background: Trunk reconstruction following sarcoma excision involves significant defects. Pedicled and free latissimus dorsi myocutaneous flap (LDMF) reconstruction is commonly employed for thoracic defects; however, skin paddle design is limited to 10-12 cm to achieve primary donor closure. Paucity of data exists regarding the utility of V-Y advancement of LDMF, previously described for moderately sized thoracic defects.

Introduction: The prognostic impact of human leukocyte antigen-E (HLA-E) expression and the proportion of natural killer (NK) cells in esophageal squamous cell carcinoma (ESCC) was investigated.
Methods: This study retrospectively evaluated 397 ESCC patients across two centers. The cumulative incidence of recurrence (CIR) and the incidence of tumor-related death (CID) were analyzed in various groups.
