Aging is a physiological process characterized by the gradual decline of the body's functions over time.In recent years, the emergence of molecular hydrogen(H 2)medicine has introduced novel approaches to the field of anti-aging.Numerous animal experiments and clinical trials have demonstrated that H 2 possesses considerable potential to regulate oxidative stress, inflammation, organelle energy metabolism, and programmed cell death, while also offering protective effects on various organs and systems.Currently, H 2 is being utilized in the prevention and treatment of various age-related diseases, thereby opening new avenues for anti-aging interventions.

Objective To investigate the effects of neurotrophic factor Neuritin overexpression on the angiogenic effects of chicken embryonic allantoic membrane (CAM) and human umbilical vein endothelial cells (HUVECs),and to provide a new direction for the treatment of angiogenic diseases. Methods Thirty fresh yellow-skinned breeding eggs were selected to establish a CAM model,which were divided into three groups by randomized numerical table method:positive control group (bFGF),negative control group (NS) and experimental group (Neuritin),with 10 eggs in each group. The positive control group was loaded with 2500 U/mL of bFGF,the experimental group was loaded with 10 μg/mL of Neuritin protein,and the negative control group was loaded with NS. 10 μL loading volume was loaded into each group,and all CAMs were incubated at the same temperature,relative humidity,and time,and the vascular branching,number,and size of the CAMs in each group were recorded after 72 h of incubation. Fresh umbilical cords from healthy pregnant women were selected to produce primary HUVECs,which were divided into three groups:transfected with recombinant plasmid (HUVEC-neu group),transfected with empty vector (HUVEC-3.1 group),and untransfected (HUVEC group). Primary HUVECs in the HUVEC-neu group were transfected with the recombinant plasmid Neuritin,and those in the HUVEC-3.1 group were transfected with the empty vector. HUVEC-3.1 group was transfected with the empty vector plasmid,and HUVEC group was not given any special treatment,and all three groups received the same culture regimen. Western blot was used to detect the protein expression level of Neuritin in HUVEC-3.1 and HUVEC-neu groups. CCK-8 assay,cell scratch assay,Transwell assay,and tube formation assay were used to detect protein expression level of Neuritin in HUVEC-3.1 group and HUVEC-neu group,and HUVEC-neu groups for cell proliferation,migration and tube formation. Results (1) The number of CAM vessel branch points and microvessels in the experimental group was significantly increased compared with that in the negative control group (P<0.01),but there was no statistically significant difference in the number of large and medium-sized vessels between the two groups (P>0.05);(2) Neuritin was successfully overexpressed in HUVECs in the HUVEC-neu group. (3) Compared with the HUVEC-3.1 group,the proliferation vigor of cells in the HUVEC-neu group was decreased (P<0.05),but their migration and tube formation abilities were significantly enhanced (P<0.01). Conclusion Neuritin overexpression promotes angiogenesis and participates in the regulation of neovascularization by affecting cell prolif-eration,migration,and tube formation ability.

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.
