ObjectiveTo observe the expression levels of related cytokines in the vitreous humor of eyes with rhegmatogenous retinal detachment (RRD) associated with lattice degeneration (LD). MethodsA clinical observational study. From May 2022 to February 2023, 43 patients of 43 eyes diagnosed with RRD, with or without accompanying LD, who underwent their first pars plana vitrectomy (PPV) at Zhongda Hospital Southeast University and The Affiliated Eye Hospital of Nanjing Medical University were included in the study. The patients were divided into two groups: RRD with LD (LD group), consisting of 27 patients with 27 eyes, and RRD without LD (Non-LD group), consisting of 16 patients with 16 eyes. Additionally, 6 patients (6 eyes) with idiopathic macular holes and 4 patients (4 eyes) with idiopathic epiretinal membranes during the same period were selected as the control group. Before initiating PPV and without intraocular perfusion, a 0.5 ml sample of undiluted vitreous fluid from the central portion was excised and aspirated. The concentrations of monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (MIP)-1α, MIP-1β, interferon-γ- inducible protein 10 (IP-10), interleukin-6 (IL-6), IL-8, macrophage migration inhibitory factor (MIF), tumor necrosis factor-alpha-α, interferon-γ, intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule-1, platelet endothelial cell adhesion molecule 1 (PECAM-1), placental growth factor (PLGF) and vascular endothelial growth factor (VEGF) in the vitreous fluid were quantitatively measured using the Luminex high-throughput multiplex assay technology. The comparison of cytokine expression levels between groups was performed using the Kruskal-Wallis rank sum test, with significance levels for post-hoc pairwise comparisons adjusted by DSCF methods. ResultsThe eyes of the patients in the LD group, Non-LD group, and control group showed statistically significant differences (P＜0.05) in the concentrations of IL-6 (H=14.400), IL-8 (H=13.610), MCP-1 (H=12.050), VEGF (H=9.920), MIP-1α (H=6.620), IP-10 (H=7.780), MIF (H=12.920), PECAM-1 (H=9.990), ICAM-1 (H=8.070), and PLGF (H=16.850). Upon pairwise comparison between groups, the vitreous fluid concentrations of IL-6, IL-8, and PLGF in the LD group were found to be significantly higher than those in the Non-LD group (P＜0.05). ConclusionThe expression levels of IL-6, IL-8, and PLGF are elevated in the vitreous fluid of eyes with RRD accompanied by LD.

Objective To summarize the clinical data about mediastinal lesions, then to analyze the treatment effect of da Vinci robot system in the surgical treatment of mediastinal lesions. Methods We retrospectively analyzed the clinical data of 49 patients with mediastinal lesions in our hospital between January 2016 and October 2017. These patients were divided into two groups including a da Vinci robot group and a video-assisted thoracoscopic surgery (VATS) group according to the selection of the treatments. There were 25 patients with 14 males and 11 females at age of 56.5±17.9 years in the da Vinci group and 24 patient with 15 males and 11 females at age of 53.0±17.8 years in the VATS group. Results There was no statistical difference in surgery time between the two groups (t=–0.365, P=0.681). Less intraoperative blood loss (t=–2.569, P<0.001), less postoperative drainage amount within three days after surgery (t=–6.325, P=0.045), shorter period of bearing drainage tubes after surgery (t=–1.687, P=0.024), shorter hospital stays (t=–3.689, P=0.021), lower visual analogue scale (VAS) scores of postoperative 48 hours (t=–7.214, P=0.014) with a statistical difference in the da Vinci robot group compared with the VATS group. Conclusion The da Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach.
ObjectiveTo evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer.MethodsWe retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared.ResultsThere was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021).ConclusionThe da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted thoracic surgery (RATS) and video assisted thoracic surgery (VATS) for patients with non-small cell lung cancer (NSCLC). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 9, 2016), Web of Science, CNKI, VIP, WanFang Data and CBM databases to collect clinical studies about RATS vs. VATS for patients with NSCLC from inception to October 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 19 921 patients were included; among them, 4 322 cases were in the RATS group, and 15 599 were in the VATS group. The results of meta-analysis showed that the operation time (MD=22.90, 95%CI 9.97 to 35.84, P<0.000 5) was longer in the RATS group than the VATS group. However, the conversion rate (OR=0.72, 95%CI 0.44 to 1.18, P=0.20), the incidence of postoperative complications (OR=1.06, 95%CI 0.96 to 1.17, P=0.28), intraoperative blood loss (MD=2.75, 95%CI –8.39 to 13.89, P=0.63), postoperative hospitalization time (MD=–0.00, 95%CI –0.02 to 0.02, P=0.99) and in-hospital mortality rate (OR=0.60, 95%CI 0.35 to 1.05, P=0.07) were not significant differences between both groups.ConclusionThe current meta-analysis indicates that the efficacy and safety of RATS and VATS for NSCLC is equivalence, however the operation time for RATS is longer. Due to the limited quantity and quality of inclued studies, the above conclusions still need to be verified by more high quality studies.
