Objective:To observe and analyze the correlations between aqueous humor cytokine concentrations and disorganization of retinal inner layers (DRIL), as well as postoperative visual acuity, in patients with idiopathic epiretinal membrane (iERM).Methods:A prospective clinical study. From November 2022 to October 2024, 40 eyes of 40 patients diagnosed with iERM at Ophthalmology Center of Zhejiang Provincial People's Hospital (Affiliated People's Hospital) underwent cataract surgery alone or combined with pars plana vitrectomy (iERM group) were enrolled; 19 eyes of 19 patients undergoing cataract surgery alone during the same period served as the control group. All eyes underwent best-corrected visual acuity (BCVA) testing and swept-source optical coherence tomography (SS-OCT). BCVA was assessed using a logarithmic visual acuity chart and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. Central macular thickness (CMT) was measured using SS-OCT. The iERM group was further subdivided into DRIL-positive and DRIL-negative subgroups (21 eyes and 19 eyes, respectively), based on the presence or absence of DRIL. Aqueous humor samples were collected preoperatively from eyes in both the iERM and control groups. Concentrations of transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, platelet-derived growth factor (PDGF)-AB, hepatocyte growth factor, fibroblast growth factor, vascular endothelial growth factor-A (VEGF-A), placental growth factor (PLGF), glial cell line-derived neurotrophic factor (GDNF), intercellular adhesion molecule-1 (ICAM-1), angiopoietin (Ang)-1, Ang-2, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured. Follow-up examinations using the same equipment and methods were performed at 1 month postoperatively. Aqueous cytokine levels were compared between the iERM group, control group, DRIL-positive subgroup, and DRIL-negative subgroup. Correlations between aqueous cytokine levels in the iERM group and BCVA or CMT were also analyzed. Intergroup comparisons utilized the Mann-Whitney U test; correlations between variables were assessed using Spearman's rank correlation analysis. Results:Compared to the control group, the iERM group exhibited significantly higher aqueous concentrations of TGF-β1, TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, and TNF-α ( P<0.05). Compared to the DRIL-negative subgroup, the DRIL-positive subgroup showed significantly elevated aqueous concentrations of TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, Ang-2, TNF-α, and IL-6 ( P<0.05). Significant differences were observed in logMAR BCVA ( P=0.028) and CMT ( P<0.001) within the iERM group between preoperative and 1-month postoperative measurements. LogMAR BCVA differed significantly between the DRIL-positive and DRIL-negative subgroups ( P=0.048). Correlation analysis revealed that baseline aqueous levels of VEGF-A and IL-6 in eyes with DRIL were positively correlated with postoperative BCVA ( r=0.324, 0.452; P=0.042, 0.003). No significant correlation was found between CMT and any cytokine ( P>0.05). Conclusions:Aqueous humor cytokines are closely associated with DRIL in iERM patients. IL-6 and VEGF-A may serve as potential predictive biomarkers for early postoperative visual recovery.

Objective:To evaluate whether the mechanism by which mesenchymal stem cell-derived exosomes (MSC-exo) mitigated endotoxin-induced lung injury was related to the heme oxygenase-1 (HO-1)/mitochondrial signaling pathway in alveolar macrophages of mice.Methods:In vivo experiment Eighteen C57BL/6 wild-type (WT) mice were divided into 3 groups ( n=6 each) using a random number table method: control group (C group), lipopolysaccharide (LPS) group (L group) and LPS + MSC-exo group (LM group). Six HO-1 conditional knockout mice (HO-1 -/-) were selected and served as HO-1 -/- + MSC-exo + LPS group (HML group). The model of endotoxin-induced lung injury was prepared by injection of LPS 15 mg/kg. MSC-exo (2×10 11 particles) was intravenously injected at 1 h before injection of LPS in LM group. MSC-exo (2×10 11 particles) was intravenously injected and 1 h later LPS was injected in HML group. The expression of HO-1 in macrophages was detected using immunofluorescence, lung injury was assessed following hematoxylin-eosin staining, the wet/dry weight ratio (W/D ratio) was determined, and the mitochondrial morphology was observed with a transmission electron microscope. Cell experiment Alveolar macrophages (MH-S) were divided into 4 groups ( n=20 each) using a random number table method: control group (C group), LPS+ phosphate buffer solution group (LP group), LPS+ MSC-exo group (LM group), and LPS+ MSC-exo+ HO-1 small-interfering RNA group (LMS group). Cells were incubated for 12 h with LPS 10 μg/ml in LP, LM and LMS groups. In addition, LM group was incubated with MSC-exo 100 μg/ml, LP group was incubated with the equal volume of phosphate buffer solution, and the alveolar macrophages were transfected with HO-1 small interfering RNA and incubated with MSC-exo 100 μg/ml in LMS group at the same time. The concentrations of interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in supernatant were measured by enzyme-linked immunosorbent assay, HO-1 expression was detected by Western blot, the mitochondrial membrane potential was measured using JC-1 staining, and the expression of reactive oxygen species (ROS) was detected by fluorescence. Results:In vivo experiment Compared to C group, the lung injury score and W/D ratio were significantly increased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was aggravated in L group. Compared to L group, the lung injury score and W/D ratio were significantly decreased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was reduced in LM group. Compared to LM group, the lung injury score and W/D ratio were significantly increased ( P<0.05), macrophages had no HO-1 fluorescence signal, and the damage to mitochondria was aggravated in HML group. Cell experiment Compared to C group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LP group. Compared to LP group, the concentrations of IL-1β and TNF-α in supernatant were significantly decreased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited red JC-1 fluorescence, accompanied by a weakened ROS fluorescence signal in LM group. Compared to LM group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was down-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LMS group. Conclusions:The mechanism by which MSC-exo attenuates endotoxin-induced lung injury may be related to up-regulation of HO-1 expression in alveolar macrophages and reduction of mitochondrial damage in mice.

Objective:To explore the clinical significance of skeletonized lymph node dissection of No.12 lymph nodes after neoadjuvant therapy in patients with advanced gastric cancer.Methods:For this retrospective case-cohort study we collected data from patients with advanced gastric cancer who underwent neoadjuvant chemotherapy and D2 or more extensive curative resection including No.12 lymph node dissection at the First Affiliated Hospital of Sun Yat-sen University from January, 2011 to December, 2022. Patients were divided into two groups based on whether they received skeletonized dissection of No.12 lymph nodes: 177 cases were in the skeletonized group, and 55 cases were in the nonskeletonized group. The differences of prognosis between the two groups were compared, and logistic regression models were used to analyze the factors affecting No.12 lymph node metastasis in the overall cohort and No.12b or No.12p lymph node metastasis in the skeletonized group.Results:A total of 232 patients were included, with 84 females (36.2%) and 148 males (63.8%), with an average age of 56.4±11.6 years. The proportion of female and ycT4 patients was significantly higher in the skeletonized group than in the nonskeletonized group (both P<0.05). Among all 232 patients, No. 12a metastasis occurred in 14 cases (6.0%). In the skeletonized group of 177 patients, No. 12b and No. 12p metastases were observed in 6 patients each (3.4%), and 4 patients had concurrent metastases in both No. 12b and No. 12a. The 5-year overall survival (OS) rates were 45.5% in the skeletonized group and 42.8% in the nonskeletonized group, with no statistical difference (HR=0.755, 95%CI: 0.488-1.168, P=0.580). The 5-year disease-free survival (DFS) rates were 39.8% and 41.0%, respectively, also with no statistical difference (HR=0.775, 95%CI: 0.513-1.172, P=0.584). 5-year OS for patients without No.12 lymph node metastasis was 48.8%, which was higher than the 15.9% for those with metastasis (HR=0.349, 95% CI: 0.209-0.584, P=0.003). Additionally, the 5-year DFS for those without metastasis was 44.3%, significantly higher than the 5.7% for those with metastasis (HR=0.444, 95%CI: 0.276-0.716, P<0.001). For patients without No. 12b or No. 12p lymph node metastasis, the 5-year OS was 47.6%, and the 5-year DFS was 42.3%, both of which were significantly higher than the 16.7% and 8.3% for those with No.12b or No. 12p lymph node metastasis, respectively (HR=0.353, 95%CI: 0.183-0.681, P=0.005; HR=0.457, 95%CI: 0.244-0.855, P=0.006). Multivariate analysis showed that more advanced ypN stage (OR=3.908, 95%CI:1.638-9.323, P=0.002) and tumor location in the lower stomach or whole stomach (OR=3.533, 95%CI: 1.312-9.511, P=0.012) were independent risk factors for No.12 lymph node metastasis and also for No.12b and No.12p lymph node metastasis (OR=2.426, 95%CI: 1.212-4.856, P=0.012 and OR=4.908, 95%CI:1.182-20.373, P=0.028, respectively). Conclusion:Patients with advanced gastric cancer who have more advanced ypN stage and tumor location in the lower stomach or whole stomach have a higher risk of No.12b and No.12p metastasis and thus require further skeletonized lymph node dissection of No.12.

Objective:To observe and analyze the correlations between aqueous humor cytokine concentrations and disorganization of retinal inner layers (DRIL), as well as postoperative visual acuity, in patients with idiopathic epiretinal membrane (iERM).Methods:A prospective clinical study. From November 2022 to October 2024, 40 eyes of 40 patients diagnosed with iERM at Ophthalmology Center of Zhejiang Provincial People's Hospital (Affiliated People's Hospital) underwent cataract surgery alone or combined with pars plana vitrectomy (iERM group) were enrolled; 19 eyes of 19 patients undergoing cataract surgery alone during the same period served as the control group. All eyes underwent best-corrected visual acuity (BCVA) testing and swept-source optical coherence tomography (SS-OCT). BCVA was assessed using a logarithmic visual acuity chart and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. Central macular thickness (CMT) was measured using SS-OCT. The iERM group was further subdivided into DRIL-positive and DRIL-negative subgroups (21 eyes and 19 eyes, respectively), based on the presence or absence of DRIL. Aqueous humor samples were collected preoperatively from eyes in both the iERM and control groups. Concentrations of transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, platelet-derived growth factor (PDGF)-AB, hepatocyte growth factor, fibroblast growth factor, vascular endothelial growth factor-A (VEGF-A), placental growth factor (PLGF), glial cell line-derived neurotrophic factor (GDNF), intercellular adhesion molecule-1 (ICAM-1), angiopoietin (Ang)-1, Ang-2, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured. Follow-up examinations using the same equipment and methods were performed at 1 month postoperatively. Aqueous cytokine levels were compared between the iERM group, control group, DRIL-positive subgroup, and DRIL-negative subgroup. Correlations between aqueous cytokine levels in the iERM group and BCVA or CMT were also analyzed. Intergroup comparisons utilized the Mann-Whitney U test; correlations between variables were assessed using Spearman's rank correlation analysis. Results:Compared to the control group, the iERM group exhibited significantly higher aqueous concentrations of TGF-β1, TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, and TNF-α ( P<0.05). Compared to the DRIL-negative subgroup, the DRIL-positive subgroup showed significantly elevated aqueous concentrations of TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, Ang-2, TNF-α, and IL-6 ( P<0.05). Significant differences were observed in logMAR BCVA ( P=0.028) and CMT ( P<0.001) within the iERM group between preoperative and 1-month postoperative measurements. LogMAR BCVA differed significantly between the DRIL-positive and DRIL-negative subgroups ( P=0.048). Correlation analysis revealed that baseline aqueous levels of VEGF-A and IL-6 in eyes with DRIL were positively correlated with postoperative BCVA ( r=0.324, 0.452; P=0.042, 0.003). No significant correlation was found between CMT and any cytokine ( P>0.05). Conclusions:Aqueous humor cytokines are closely associated with DRIL in iERM patients. IL-6 and VEGF-A may serve as potential predictive biomarkers for early postoperative visual recovery.

As one of the most difficult-to-cure neuropsychiatric disorders in clinical practice， schizophrenia is mainly manifested by behavioral abnormalities and multidimensional cognitive dysfunction， and the recurrence rate and disability rate of the disease are increasing year by year， which seriously affects patients' social functioning and quality of life， and even threatens the physical and mental health of the surrounding population. At present， the treatment of schizophrenia is mainly based on antipsychotic drugs combined with psychotherapeutic techniques， which have limited long-term therapeutic effects and a high relapse rate. Traditional Chinese medicine （TCM） boasts the advantages of multi-targets， multi-pathways， multi-links， and multi-levels， and plays a crucial role in the prevention and treatment of schizophrenia and its prognosis. Phosphatidylinositol 3-kinase （PI3K） is widely present in cells and is involved in the regulation of protein synthesis and apoptosis， and the different isoforms of protein kinase B （Akt） are of great significance in cell growth， oxidative stress， neuronal development and other processes. In recent years， a large number of studies have found that the PI3K/Akt signaling pathway is closely related to schizophrenia. Through regulating the PI3K/Akt signaling pathway， TCM monomers and TCM compounds mainly affect key signaling molecules such as mammalian target of rapamycin （mTOR）， glycogen synthase kinase （GSK）， glucose transporter （GLUT） for glucose uptake and transport， and nuclear factor E₂-associated factor 2 （Nrf2）， which organize the intracellular network of centers and regulate the formation and plasticity of neuronal synapse， and they play an important role in mitigating schizophrenia by regulating the processes of cell proliferation， migration and apoptosis of neurons， and has the advantages of multi-targets， all-encompassing and low toxicity. This article analyzes and explains the mechanism of TCM intervention in the PI3K/Akt signaling pathway against schizophrenia， in order to provide a theoretical basis and reference for the prevention and treatment of schizophrenia by TCM.

Myocardial fibrosis is an important pathological process in the development of cardiovascular diseases, which is closely related to the prognosis of patients. Activated cardiac fibroblasts (CFs) are the main effector cells, whose surface specifically overexpress fibroblast activation protein (FAP). Radionuclide-labeled FAP inhibitors (FAPIs) can specifically bind to FAP to visualize activated CFs in vivo, showing preliminary clinical application in the early diagnosis, prognosis prediction and interventional guidance of various cardiovascular diseases. This article reviews the progress of researches on the application of radionuclide-labeled FAPIs in cardiovascular diseases imaging.
