Background: Visual impairment is increasingly prevalent, underscoring the need for effective prevention strategies. This study investigated the association between cardiovascular health and visual impairment using three progressively developed metrics: Life’s Simple 7 (LS7), a cardiovascular health score developed by the American Heart Association based on 7 components, including physical activity, smoking status, body mass index (BMI), diet, blood glucose, blood pressure, and total cholesterol; Life’s Essential 8(LE8), which adds sleep health as an additional component; and Life’s Crucial 9 (LC9), which further incorporates mental health. We aimed to evaluate whether these expanded metrics provide additional explanatory value and to inform future public health strategies. Objective: To investigate the associations among LS7, LE8, and LC9 cardiovascular health scores and visual impairment in National Health and Nutrition Examination Survey 2013 to 2018, assess the added value of sleep and mental health components, and identify key contributing subcomponents using regression and machine learning methods. Methods: We analyzed data from 9891 participants in the 2013 to 2018 National Health and Nutrition Examination Survey. Multivariable logistic regression, restricted cubic spline modeling, and subgroup analyses were conducted to evaluate the association between cardiovascular health and visual impairment. Machine learning methods, including Random Forest and SHapley Additive exPlanations, a model interpretation approach used to assess feature importance, were applied. The Boruta algorithm, a feature selection method, was used to identify key subcomponents of cardiovascular health. Results: Participants with visual impairment were older, had lower poverty-to-income ratios, and exhibited lower cardiovascular health scores (LS7, LE8, and LC9). Higher cardiovascular health scores were negatively associated with visual impairment. Each one standard deviation increase in LS7, LE8, and LC9 was associated with approximately 8%, 2%, and 3% lower odds of visual impairment, respectively. LS7 showed the strongest negative association, whereas LE8 and LC9 emerged as the most important predictors in the machine learning models. Key subcomponents such as blood glucose, blood pressure, and BMI, as well as mental health status, were strongly associated with visual impairment. Conclusion: Higher cardiovascular health scores were negatively associated with visual impairment. LS7 demonstrated the strongest statistical association, whereas LE8 and LC9 were the most influential features in the machine learning models. Blood glucose, blood pressure, BMI, and mental health status were important correlates of visual impairment. From the perspective of the “prevention and treatment of diseases” in traditional Chinese medicine and the holistic concept, the aforementioned research findings confirm that severe visual impairment is indeed an external manifestation of overall health imbalance (such as organ dysfunction and Qi deficiency and blood stasis). The prevention strategy lies in comprehensively adjusting lifestyle, emotional factors, and metabolic indicators (corresponding to the key factors in the study) to restore the body’s internal balance and achieve prevention before disease arises.

Objective To investigate the independent risk factors affecting the prognosis of chronic active antibody-mediated rejection (caAMR) after kidney transplantation. Methods A retrospective analysis was conducted on 61 patients who underwent renal biopsy and were diagnosed with caAMR. The patients were divided into caAMR group (n=41) and caAMR+TCMR group (n=20) based on the presence or absence of concurrent acute T cell-mediated rejection (TCMR). The patients were followed up for 3 years. The value of 24-hour urinary protein and estimated glomerular filtration rate (eGFR) at the time of biopsy in predicting graft loss was assessed using receiver operating characteristic (ROC) curves. The independent risk factors affecting caAMR prognosis were analyzed using the LASSO-Cox regression model. The correlation between grouping, outcomes, and Banff scores was compared using Spearman rank correlation matrix analysis. Kaplan-Meier analysis was used to evaluate the renal allograft survival rates of each subgroup. Results The 3-year renal allograft survival rates for the caAMR group and the caAMR+TCMR group were 83% and 79%, respectively. The area under the ROC curve (AUC) for predicting 3-year renal allograft loss was 0.83 ［95% confidence interval (CI) 0.70-0.97］ for eGFR and 0.78 (95% CI 0.61-0.96) for 24-hour urinary protein at the time of biopsy. LASSO-Cox regression analysis and Kaplan-Meier analysis showed that eGFR≤25.23 mL/(min·1.73 m²) and the presence of donor-specific antibody (DSA) against human leukocyte antigen (HLA) class I might be independent risk factors affecting renal allograft prognosis, with hazard ratios of 7.67 (95% CI 2.18-27.02) and 5.13 (95% CI 1.33-19.80), respectively. A strong correlation was found between the Banff chronic lesion indicators of renal interstitial fibrosis and tubular atrophy (P<0.05). Conclusions The presence of HLA class I DSA and eGFR≤25.23 mL/(min·1.73 m²) at the time of biopsy may be independent risk factors affecting the prognosis of caAMR.

Objective: To investigate the correlation between peripheral blood CD4 T lymphocyte subsets and delayed graft function (DGF) and short-term prognosis in kidney transplant recipients, so as to help optimize preoperative assessment for kidney transplantation and provide insights into the immune mechanisms of DGF. Methods: A retrospective analysis was conducted on the clinical data of 103 kidney transplant recipients at the First Affiliated Hospital of Soochow University during Jun.2022 and Oct.2023. A total of 61 recipients were finally included in this study, and were categorized into two groups based on postoperative renal function recovery：the DGF group (n=20) and the immediate graft function (IGF) group (n=41).Flow cytometry was used to detect the proportions and absolute counts of various CD4 T lymphocyte subsets in the peripheral blood on postoperative day 7.The clinical data and peripheral blood lymphocyte subsets between the two groups were compared.For the subsets that exhibited significant differences, the correlation between their proportions and absolute counts and serum creatinine (Scr) levels on postoperative day 7 was further analyzed in the DGF group.Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was calculated to evaluate the predictive performance of the most strongly correlated CD4 T lymphocyte subset in terms of proportion and absolute count for short-term renal function. Results: There were no statistically significant differences in the proportions and absolute counts of Th1, Th2, Th17, and regulatory T cells (Treg) between the DGF and IGF groups (P>0.05).The proportions and absolute counts of follicular helper T cells (Tfh) and PD-1 Tfh cells were significantly higher in the DGF group than in the IGF group (P＜0.000 1). The Scr levels at 1 month and 1 year postoperatively were significantly higher in the DGF group than in the IGF group (P＜0.01), while the estimated glomerular filtration rate (eGFR) was significantly lower in the DGF group compared with the IGF group (P＜0.01, P=0.02).Spearman correlation analysis showed that the proportions and absolute counts of Tfh and PD-1 Tfh cell subsets were positively correlated with the Scr level on post-operative day 7 in the DGF group (P＜0.05).The ROC curve demonstrated that the AUC for the proportion of PD-1 Tfh cells in predicting Scr and eGFR at 1 month after surgery was 0.73(95%CI:0.61-0.86) and 0.75 (95%CI:0.62-0.88), respectively.Additionally, the AUC for predicting Scr and eGFR at 1 year was 0.72(95%CI:0.59-0.86) and 0.70(95%CI:0.58-0.83), respectively. Conclusion: The increase in the proportions and absolute counts of Tfh and PD-1 Tfh cells is associated with postoperative DGF of renal transplant recipients, and the proportion of PD-1 Tfh cells may help predict the short-term renal function of recipients.

ObjectiveTo investigate the mechanism by which Mingshi prescription regulates the retinal melanopsin-dopamine （Opn4-DA） axis in myopic mice to inhibit endoplasmic reticulum （ER） stress in the retina and sclera， thereby delaying axial elongation associated with myopia. MethodsSixty 4-week-old male SPF-grade C57BL/6J mice were randomly divided into a normal group， a form-deprived myopia group （FDM group）， an intrinsically photosensitive retinal ganglion cells ablation group （ipRGCs group）， a Mingshi Prescription group （MSF group， 5.2 g·kg^-1）， and an ipRGCs + MSF group （5.2 g·kg^-1）. Except for the normal group， all other groups underwent FDM modeling. Additionally， the ipRGCs and ipRGCs + MSF groups received retinal ipRGC ablation. Three weeks after modeling， the MSF and ipRGCs + MSF groups were administered Mingshi prescription via continuous gavage for six weeks. After refraction and axial length were measured in all mice， eyeballs were collected along with retinal and scleral tissues. Pathological and morphological changes in the retina， choroid， and sclera were observed using periodic acid-Schiff （PAS） staining. Western blot was employed to detect the relative protein expression levels of dopamine D1 receptor （DRD1）， C/EBP homologous protein （CHOP）， and glucose-regulated protein 78 （GRP78） in the retina， and CHOP and GRP78 in the sclera. Real-time PCR was used to detect the relative mRNA expression of Opn4， CHOP， and GRP78 in the retina， and CHOP and GRP78 in the sclera. Immunofluorescence staining （IF） was performed to detect the expression of Opn4 and DRD1 in retinal tissues. ResultsCompared with the normal group， the FDM group showed a significant myopic shift in refraction （P<0.05） and a significant increase in axial length （P<0.05）. The retinal layers were thinner， the number of ganglion cells was reduced， and collagen fibers in the sclera were loosely arranged with evident gaps. Opn4 and DRD1 protein and mRNA expression in the retina were significantly decreased （P<0.05）， while CHOP and GRP78 protein and mRNA expression in both retinal and scleral tissues were significantly increased （P<0.05）. Compared with the FDM group， the ipRGCs group exhibited further increases in myopic refraction and axial length （P<0.05）， more pronounced thinning and looseness in the retinal， choroidal， and scleral layers， lower expression of Opn4 and DRD1 protein and mRNA in the retina （P<0.05）， and higher expression of CHOP and GRP78 protein and mRNA in the retina and sclera （P<0.05）. Compared with the FDM group， the MSF group showed significantly reduced refractive error and axial length （P<0.05）， with improved cellular number， arrangement， and thickness in ocular tissues， increased Opn4 and DRD1 protein and mRNA expression in the retina （P<0.05）， and reduced CHOP and GRP78 protein and mRNA expression in both retina and sclera （P<0.05）. Similarly， the ipRGCs + MSF group showed significant improvements in terms of the above items compared with the ipRGCs group （P<0.05）. ConclusionMingshi Prescription delays myopic axial elongation and refractive progression by regulating the Opn4-DA axis in the retina of myopic mice， thereby inhibiting ER stress in the retina and sclera. This intervention promotes Qi and blood nourishment of the eyes， softens the fascia， and restores ocular rhythm.

Diabetic retinopathy(DR)is one of the major complications of diabetes mellitus, characterized by neurodegeneration and microangiopathy. Currently, the treatment of DR is mainly focused on the management of late complications and has not achieved the desired clinical outcome. Evidence suggests that the PI3K/AKT pathway, as one of the important intracellular signaling pathways during the cell cycle, is involved in the whole process of DR pathogenesis. This article focuses on the structural composition, activation and blocking pathways, conduction pathways, regulatory mechanisms and biological functions of the PI3K/AKT signaling pathway to review its role in DR and to explore the potential of targeting the PI3K/AKT pathway for the treatment of DR.

Objective To analyze the causal relationship between serum sex steroid hormone levels and myopia with the Mendelian randomization(MR)methods.Methods Sex hormone genetic tools classified by sex were publicly availa-ble summarized statistical data from the Genome-wide association study(GWAS)of the UK Biobank Consortium on sex hormone-binding globulin(SHBG),total testosterone(TT),bioavailable testosterone(BT),and estradiol(E2).The GWAS summarized statistical data for myopia were obtained from publicly available data published by the FinnGen Consorti-um R10.All data were downloaded from April 18 to April 31,2024 from the corresponding databases and analyzed.All re-sults from the MR study were mainly analyzed by inverse-variance weighting(IVW)method.Results The study showed that a higher serum SHBG level in European increased the risk of myopia development in women(IVW,OR=1.152,95％CI:1.014-1.308,P=0.029);low serum TT level(IVW,OR=0.821,95％CI:0.697-0.967,P=0.018)and serum BT lev-el(IVW,OR=0.820,95％CI:0.691-0.972,P=0.022)increased the risk of myopia development in women.There was no causal relationship between serum SHBG,TT,and BT levels and myopia in men.There was no causal effect between E2 level and myopia in women and men.The stability of our findings was supported by sensitivity analysis.Conclusion In-creased serum SHBG level and decreased serum TT and BT levels are associated with an increased risk of myopia in women,whereas no such association is found in men.There is no causal relationship between E2 and myopia.

Objective To analyze the correlation between internal iliac artery calcification and delayed graft function (DGF) and short-term prognosis of kidney transplant recipients. Methods Clinical data of 222 kidney transplant recipients were retrospectively analyzed. According to the recovery of renal function, all recipients were divided into the DGF group (n=50) and immediate graft function (IGF) group (n=172). According to whether the recipients were complicated with severe internal iliac artery calcification, DGF and IGF groups were further divided into the high-risk DGF (n=22), low-risk DGF (n=28), high-risk IGF (n=41) and low-risk IGF(n=131) subgroups, respectively. Clinical data of donors and recipients were statistically compared between two groups. The incidences of postoperative DGF and internal iliac artery calcification were recorded. The risk factors of DGF after kidney transplantation, and the correlation between internal iliac artery calcification and clinical parameters were analyzed. Short-term prognosis of recipients with DGF complicated with severe internal iliac artery calcification was evaluated. Results The incidence of DGF was 22.5% (50/222). Among all recipients, 28.4% (63/222) were complicated with severe internal iliac artery calcification. In the DGF group, 44% (22/50) of the recipients were complicated with severe internal iliac artery calcification, higher than 23.8% (41/172) in the IGF group (P < 0.05). Univariate analysis showed that high serum creatinine (Scr) level of donors, male donor, high triglyceride level and severe internal iliac artery calcification of recipients were the risk factors for DGF after kidney transplantation (all P < 0.05). Multivariate logistic regression analysis revealed that Scr≥143 μmol/L of donors and severe internal iliac artery calcification of recipients were the independent risk factors for DGF after kidney transplantation (both P < 0.05). Correlation analysis indicated that internal iliac artery calcification was weakly correlated with the age of recipients and renal artery anastomosis (both P < 0.05). In the DGF group, the Scr level at postoperative 1 month was significantly higher, whereas the estimated glomerular filtration rate (eGFR) was significantly lower than those in the IGF group (both P < 0.05). The eGFR at postoperative 12 months in the high-risk DGF subgroup was significantly lower than those in the low-risk DGF, high-risk IGF and low-risk IGF subgroups (all P < 0.05). Conclusions Internal iliac artery calcification is not only a risk factor for recovery of renal allograft function, but also negatively affects short-term prognosis of renal allograft function.

【Objective】 To explore the effects of early application of erythropoietin (EPO) in patients with anemia after renal transplantation. 【Methods】 Patients who underwent renal transplantation in the First Affiliated Hospital of Soochow University were retrospectively analyzed. According to whether EPO was applied after operation, the patients were divided into EPO group and routine group. Patients with delayed renal function recovery were excluded, and the remaining patients were further analyzed. The general, laboratory and follow-up data of the two groups were compared, and adverse drug reactions were observed. 【Results】 The hemoglobin (P=0.026), red blood cell count (P=0.038) and hematocrit (P=0.011) in EPO group were higher than those in the routine group 2 weeks after operation, while the postoperative serum creatinine level was lower (P=0.001). Since the first week after operation, the reticulocyte count in EPO group was significantly higher than that in routine group (P<0.01). There was a negative correlation between hemoglobin and serum creatinine in EPO group at week 1 (r=-0.375, P=0.010) and week 2 (r=-0.386, P=0.008). During the treatment, 6 patients showed transient elevation of serum potassium, which returned to normal after symptomatic treatment, and no obvious adverse drug reactions were observed. 【Conclusion】 Continuous application of erythropoietin in the early stage after renal transplantation can significantly improve anemia in renal transplant patients and promote the recovery of renal function.
