Abstract
PURPOSE We explore the choroid vasculature changes of acute Vogt-Koyanagi-Harada (VKH) disease using widefield optical coherence tomography angiography (OCTA). METHODS In this retrospective, observational, longitudinal study, 16 patients with acute VKH disease (32 eyes, mean age: 42.19 ±13.66 years) were measured using widefield OCTA. RESULTS In this study, we first described the multiple dark foci in choriocapillaris and Sattler's layer in the panoramic montage of the five 12x12mm images in 30 eyes (93.8%) of acute VKH disease. OCTA follow-up in these 30 eyes demonstrated the diminished size and number of these dark foci in choriocapillaris and Sattler's layer after the initiation of treatment. CONCLUSIONS Widefield OCTA enables noninvasive identification of characteristics of flow void at the level of superficial choroidal vessels in the acute phase and may be a novel valuable tool for diagnosis and monitoring of disease progression in VKH disease in the future.

Abstract
PURPOSE To investigate the clinical features, risk factors, and prognosis of the intraocular recurrence in primary vitreoretinal lymphoma (PVRL). DESIGN Retrospective case-control study. PARTICIPANTS Ninety-seven eyes of 51 patients diagnosed with PVRL between December 2011 and January 2021 were enrolled in this study. Fourteen patients among them had experienced intraocular recurrence. METHODS Data on demographic and ophthalmic characteristics, results of diagnostic tests, treatments, and prognosis of intraocular recurrence and nonrecurrence for PVRL patients were collected and compared. Multivariate logistic regression was used to identify independent risk factors. Receiver operating characteristic curves were used to determine the cutoff values. MAIN OUTCOME MEASURES Clinical features and risk factors. RESULTS Fourteen (19 eyes) of 51 PVRL patients had intraocular recurrences, resulting in a recurrence rate of 27.5% over a mean follow-up period of 42.5 months. No difference was observed in central nervous system lymphoma (CNSL) relapse rate (54.3% vs. 64.3%, P = 0.52) or median time to CNSL (36.5 months; 95% confidence interval [CI], 24.6-48.3 vs. 37.3 months; 95% CI, 24.8-49.8; P = 0.78) between intraocular nonrecurrence and intraocular recurrence groups. Furthermore, there were no statistically significant differences in the survival outcomes, such as mortality (28.6% vs. 29.7%, P = 1.00) and median overall survival (70.8 months; 95% CI, 54.0-87.7 vs. 59.2 months; 95% CI, 44.8-73.6; P = 0.30), between these 2 groups. Younger onset age (odds ratio [OR] 0.90; 95% CI, 0.84-0.98; P = 0.010), isolated PVRL (OR, 35.3; 95% CI, 2.08-600.0; P = 0.014), and no history of intravitreal chemotherapy (OR, 7.72; 95% CI, 1.37-43.6; P = 0.021) were identified as independent risk factors for intraocular recurrences. Of the patients with intraocular recurrence, 23.6% were asymptomatic and were diagnosed during routine follow-up. The rate of interleukin-10 (IL-10)/interleukin-6 > 1 was significantly lower than that at diagnosis (43.8% vs. 92.3%, P = 0.008). However, the rate of IL-10 ≥ 50 pg/mL was high (81.3%) and not significantly different from that at diagnosis (92.3%, P = 0.61). CONCLUSIONS This study did not identify an impact of intraocular recurrence on CNS manifestations or survival outcomes in patients with PVRL. Younger patients have a higher risk of intraocular recurrence, and combined systemic and intravitreal chemotherapy may reduce intraocular recurrence. Regular ophthalmic follow-up and IL-10 testing are recommended to detect intraocular recurrence.

Abstract
AIM To evaluate the association between computed tomography (CT)-based imaging variables at the time of admission and haemorrhagic transformation (HT) after intravenous thrombolysis (IVT). MATERIALS AND METHODS One hundred and eight patients who were treated with IVT for acute ischaemic stroke (AIS) during January 2021 to July 2023 were analysed retrospectively. The infarct location was classified as cortical or subcortical in accordance with the Alberta Stroke Program Early CT Score (ASPECTS) system. Logistic regression and receiver operating characteristic curve analyses were performed to determine the relationship between ischaemic variables and HT. RESULTS Of the total, 18 (16.7%) patients had HT and seven (6.5%) had symptomatic intracerebral haemorrhage (sICH). Multivariate analysis revealed that cortical ASPECTS was independently associated with HT (odds ratio [OR], 0.197; 95% confidence interval [CI], 0.076-0.511; p=0.001) and cortical ASPECTS was independently associated with sICH (OR, 0.066; 95% CI, 0.009-0.510; p=0.009). To predict HT and sICH, cortical ASPECTS (HT area under the curve [AUC] = 0.881, sICH AUC = 0.971) provided a higher AUC compared with ASPECTS (HT AUC = 0.850, sICH AUC = 0.918). CONCLUSION Cortical ASPECTS seen on CT at the time of admission is associated with HT and sICH after IVT.

Abstract
PURPOSE To explore the characteristics of vitreoretinal lymphoma (VRL) in B-scan ultrasonography. DESIGN Single-center case-control study. PARTICIPANTS A total of 106 eyes of 56 patients with biopsy-proven VRL and 86 eyes of 59 patients with uveitis were included. METHODS B-scan ultrasonography of the included eyes was performed. Evaluated were the ultrasonographic signs as well as a special pattern termed centrifugal condensation, which refers to the peripherally hyperreflective appearance of the vitreous haze in ultrasonography. MAIN OUTCOME MEASURES Posterior vitreous detachment, vitreoretinal adhesion, location of vitreous haze, thickening or occupying lesions of the retina, retinal detachment, and centrifugal condensation pattern of vitreous haze were evaluated through B-scan ultrasonography. The incidences of these signs were compared between the 2 groups; odds ratios (ORs) were calculated. RESULTS The incidence of vitreoretinal adhesion in patients with VRL (6/106) was lower than in patients with uveitis (20/86; P = 0.001; OR: 0.195; 95% confidence interval [CI]: 0.073-0.522). The incidence of retinal thickening or occupying lesions in patients with VRL (21/106) was higher than that in patients with uveitis (1/86; P = 0.005; OR: 19.068; 95% CI: 2.455-148.265). The incidences of posterior vitreous detachment and retinal detachment were not significantly different between the 2 groups (P = 0.453 and P = 0.310, respectively). The centrifugal condensation pattern was more likely to be observed in patients with VRL (49/106) than in patients with uveitis (13/86; P < 0.001; OR: 4.831; 95% CI: 2.416-9.660). CONCLUSIONS B-scan ultrasonography might help to provide clues for the suspicion of VRL. Thickening or occupying lesions of the retina and centrifugal condensation pattern of vitreous haze might be suggestive of VRL.

Abstract
Myopia is widely recognized as an epidemic. Studies have found a link between Transforming Growth Factor-beta (TGF-β) and myopia, but the specific molecular mechanisms are not fully understood. In this study, a monocular model in tree shrews (Tupaia belangeri) was established to verify the molecular mechanism of TGF-β in myopia. The results indicated that there were significant changes in TGF-βs during the treatment of myopia, which could enhance the refractive ability and axial length of the eye. Immunohistochemical staining, real-time fluorescent quantitative PCR, and immunoblotting results showed a significant upregulation of MMP2 and NF-κB levels, and a significant downregulation of COL-I expression in the TGF-β treated eyes, suggesting that NF-κB and MMP2 are involved in the signaling pathways of TGF-βs induced myopia and axial elongation. Moreover, the expression levels of IL-6, IL-8, MCP-1, IL-1β, TNF-α, TAK1, and NF-κB in the retina were all significantly elevated. This indicates that TGF-β stimulates the inflammatory response of retinal pigment epithelial cells through the TAK1-NF-κB signaling pathway. In conclusion, this study suggests that TGF-β promotes the progression of myopia by enhancing intraocular inflammation.

Abstract
Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This is a retrospective case series study. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged (M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery. There were 15 cases of the right coronary artery from the left aortic sinus of Valsalva, 6 cases of left coronary artery from the right aortic sinus of Valsalva, 3 cases of the sigle coronary artery. Only 3 patients had no obvious related symptoms (2 cases were complicated with a positive exercise stress test and 1 case with other intracardiac malformations), 21 cases had a history of chest tightness, chest pain, or syncope after exercise. Three patients suffered syncope after exercise and underwent cardiopulmonary resuscitation (2 cases were treated with an extracorporeal membrane oxygenerator (ECMO)). The gap from the first symptom to the diagnosis was 4.0 (11.5) months (range: 0.2 to 84.0 months). The detection rate of coronary artery abnormalities suggested by the first cardiac ultrasound was only 37.5% (9/24). Seven patients were complicated with other cardiac diseases (4 cases with congenital heart defects, 2 cases with coronary atherosclerotic heart disease, 1 case with mitral valve disease). Results: All 24 patients underwent surgical treatment (23 cases underwent abnormal coronary artery unroofing, 1 case underwent coronary artery bypass grafting), and 5 patients underwent other intracardiac malformation correction at the same time. There were no death or surgery related complications in the hospital for 30 days after the operation. A patient with preoperative extracorporeal cardiopulmonary resuscitation was continuously assisted by ECMO after emergency AAOCA correction and had complications such as limb ischemia necrosis and renal dysfunction after the operation. During the follow-up of 2.2 (3.3) years (range: 1 month to 7.2 years), one patient who previously underwent percutaneous transluminal coronary angioplasty with a stent implant experienced significant postoperative symptomatic relief, and the other discharged patients had no related symptoms. Conclusions: The accurate rate of initial diagnosis for high-risk AAOCA is still low, but the risk of cardiovascular accidents is high. For sports-related chest pain and other symptoms, more attention should be paid to the detection of AAOCA, especially for adolescents. Exercise stress testing can be helpful in evaluating the cardiovascular risk of asymptomatic AAOCA. Instant surgical treatment can achieve satisfactory curative effects.

Abstract
PURPOSE To investigate the characteristics of spontaneously closed full-thickness macular holes (FTMHs) and to seek potential predictors for the spontaneous closure of FTMHs. METHODS In this retrospective cohort study, the clinical data and optical coherence tomography images were reviewed from 19 eyes with spontaneously closed FTMHs (spontaneous closure group) and 37 control eyes with FTMHs that were delayed for nonmedical reasons, but ultimately required surgery (control group). The term, suspended hyperreflective material, was defined as hyperreflective material suspended within the FTMHs observed via optical coherence tomography; the presence of suspended hyperreflective material was evaluated in these eyes. RESULTS The median time from diagnosis to spontaneous closure of the FTMHs was 13.7 (range, 2.4-32.4) weeks in the spontaneous closure group. The mean diameter of FTMHs in the spontaneous closure group was significantly smaller than that in the control group (191.68 ± 70.57 vs. 401.68 ± 162.19 µ m, P < 0.0001). The incidence of vitreomacular traction was higher in the spontaneous closure group compared with the control group (9/19 vs. 5/37, P = 0.009, odds ratio [95% confidence interval], 5.76 [1.56-21.21]); in seven of the nine eyes with vitreomacular traction from the spontaneous closure group, spontaneous vitreomacular traction separation and subsequent FTMH closure was observed. Suspended hyperreflective material was observed in nine eyes (47%) from the spontaneous closure group and three eyes (8%) from the control group ( P = 0.001, odds ratio [95% confidence interval], 10.20 [2.31‒45.02]). CONCLUSION Smaller diameters, vitreomacular traction, and presence of suspended hyperreflective material may be suggestive of the potential for spontaneous closure of FTMHs.

Abstract
BACKGROUND Circular RNAs (circRNAs) are implicated in retinal pathophysiology; however, their expression profiles and functions in photoreceptor apoptosis are largely unknown. We explored circRNA-expression profiles and circUvrag (host gene: Uvrag, ultraviolet radiation resistance associated gene) function in light-induced photoreceptor apoptosis. METHODS Sprague-Dawley rats and 661 W photoreceptor cells were exposed to blue light to establish light-induced photoreceptor degeneration. Differentially expressed circRNAs were identified using microarrays. Potential functions of dysregulated circRNAs were analysed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. CircUvrag expression and localization were evaluated using quantitative RT-PCR and fluorescence in situ hybridization, respectively. CircUvrag overexpression and knockdown were induced using a plasmid and a small interfering RNA, respectively, and retinal function and structure were assessed using scotopic electroretinography, haematoxylin-eosin staining, and TUNEL staining. Microglial migration was assessed using IBA1 immunostaining. The apoptosis ratio of photoreceptor cells in vitro was detected using flow cytometry. RESULTS We identified 764 differentially expressed circRNAs, which were potentially related with the development of retinal structures, including neurons, dendrites, and synapses, and might participate in nervous-system pathophysiology. Light exposure enriched circUvrag in the cytoplasm of photoreceptors in the outer nuclear layer (ONL). CircUvrag knockdown decreased photoreceptor apoptosis and microglial migration to the ONL after light exposure, preserving ONL thickness and a-wave amplitude. In vitro, circUvrag knockdown inhibited photoreceptor apoptosis, although circUvrag overexpression slightly promoted photoreceptor apoptosis. CONCLUSIONS CircUvrag knockdown attenuated light-induced photoreceptor apoptosis, and might be a potential target in retinal degeneration.

Abstract
BACKGROUND Monoclonal antibodies (ICI) targeting the immune checkpoint PD-1/PD-L1 alone or in combination with chemotherapy have demonstrated relevant benefits and established new standards of care in first-line treatment for advanced non-oncogene addicted non-small cell lung cancer (NSCLC). However, a relevant percentage of NSCLC patients, even with high PD-L1 expression, did not respond to ICI, highlighting the presence of intracellular resistance mechanisms that could be dependent on high PD-L1 levels. The intracellular signaling induced by PD-L1 in tumor cells and their correlation with angiogenic signaling pathways are not yet fully elucidated. METHODS The intrinsic role of PD-L1 was initially checked in two PD-L1 overexpressing NSCLC cells by transcriptome profile and kinase array. The correlation of PD-L1 with VEGF, PECAM-1, and angiogenesis was evaluated in a cohort of advanced NSCLC patients. The secreted cytokines involved in tumor angiogenesis were assessed by Luminex assay and their effect on Huvec migration by a non-contact co-culture system. RESULTS PD-L1 overexpressing cells modulated pathways involved in tumor inflammation and JAK-STAT signaling. In NSCLC patients, PD-L1 expression was correlated with high tumor intra-vasculature. When challenged with PBMC, PD-L1 overexpressing cells produced higher levels of pro-angiogenic factors compared to parental cells, as a consequence of STAT signaling activation. This increased production of cytokines involved in tumor angiogenesis largely stimulated Huvec migration. Finally, the addition of the anti-antiangiogenic agent nintedanib significantly reduced the spread of Huvec cells when exposed to high levels of pro-angiogenic factors. CONCLUSIONS In this study, we reported that high PD-L1 modulates STAT signaling in the presence of PBMC and induces pro-angiogenic factor secretion. This could enforce the role of PD-L1 as a crucial regulator of the tumor microenvironment stimulating tumor progression, both as an inhibitor of T-cell activity and as a promoter of tumor angiogenesis.

Abstract
This study reports the outcomes of a secondary IOL implantation technique in patients that suffered from rhegmatogenous retinal detachment combined with a cataract, which included reopening the capsular bag, enabling secondary intracapsular intraocular lens (IOL) implantation. We included consecutive cases with rhegmatogenous retinal detachment (RRD) treated with vitrectomy and silicone oil tamponade, and subsequent secondary IOL implantation during silicone oil removal between September 2019 and June 2022. Demographics, pre- and postoperative clinical data, and complications were collected. Visual and refractive outcomes and IOL position were evaluated. Thirty eyes were included and followed up for a mean of 24.2 ± 5.06 months. Compared with the preoperative values, no significant changes were observed in the intraocular pressure (p = 0.170) and endothelial cell density (p = 0.336); however, the best-corrected visual acuity (Snellen: 20/83 vs. 20/38; logMAR: 0.66 ± 0.23 vs. 0.37 ± 0.32; p < 0.001) and spherical equivalent (p < 0.001) improved significantly. The mean prediction error (ME) was -0.45 ± 0.68 D (-1.9-0.54 D), and the mean absolute prediction error (MAE) was 0.62 ± 0.52 D (0.01-1.9 D). The macula-on subgroup demonstrated significantly better refractive outcomes than the macula-off subgroup (ME, p = 0.046; MAE, p = 0.008). The IOL was well positioned, with a mean horizontal and vertical tilt and decentration of 0.53 ± 0.49° and 0.21 ± 0.16 mm, and 0.54 ± 0.45° and 0.22 ± 0.16 mm, respectively. Secondary intracapsular IOL implantation provided a good and stable IOL position and satisfactory refractive outcomes, and is a feasible treatment option for patients with RRD.

Abstract
AIM To develop and validate a computed tomography (CT)-based radiomics nomogram for preoperative prediction of microsatellite instability (MSI) status and clinical outcomes in colorectal cancer (CRC) patients. MATERIALS AND METHODS This retrospective study enrolled 497 CRC patients from three centres. Least absolute shrinkage and selection operator regression was utilised for feature selection and constructing the radiomics signature. Univariate and multivariate logistic regression analyses were employed to identify significant clinical variables. The radiomics nomogram was constructed by integrating the radiomics signature and the identified clinical variables. The performance of the nomogram was evaluated through receiver operating characteristic curves, calibration curves, and decision curve analysis. Kaplan-Meier analysis was performed to investigate the prognostic value of the nomogram. RESULTS The radiomics signature comprised 10 radiomics features associated with MSI status. The nomogram, integrating the radiomics signature and independent predictors (age, location, and thickness), demonstrated favourable calibration and discrimination, achieving areas under the receiver operating characteristic (ROC) curves (AUCs) of 0.89 (95% confidence interval [CI]: 0.83-0.95), 0.87 (95% CI: 0.79-0.95), 0.88 (95% CI: 0.81-0.96), and 0.86 (95% CI: 0.78-0.93) in the training cohort, internal validation cohort, and two external validation cohorts, respectively. The nomogram exhibited superior performance compared to the clinical model (p<0.05). Additionally, survival analysis demonstrated that the nomogram successfully stratified stage II CRC patients based on prognosis (hazard ratio [HR]: 0.357, p=0.022). CONCLUSION The radiomics nomogram demonstrated promising performance in predicting MSI status and stratifying the prognosis of patients with CRC.

Abstract
PURPOSE/OBJECTIVE(S) Verification of plan (VP) has been part of our pre-treatment workflow for treatment isocenter verification. Currently, our center uses simulator for VP procedure for all our patients before the treatment. We would like to investigate if SGRT could be a good substitute for VP procedure to simplify our pre-treatment workflow. MATERIALS/METHODS In Group A (A-c, A-t, A-a), 20 patients of each treatment site (cranial, thorax and abdomen) were selected randomly. Patients did not go through VP procedure. During the first fraction of treatment, the therapists were guided by SGRT system (Vision RT, UK) and aligned the patient to 3mm and 1°using a standard region of interest (ROI). First CBCT was taken as a reference to customize the ROI for better suitability. Next, the patient was re-aligned to 1mm and 1°using the new ROI. Second CBCT was acquired, and 6 degrees of freedoms shifts were recorded. In Group B (B-c, B-t, B-a), 20 patients of each treatment site (cranial, thorax and abdominal) that were assigned for VP over the same period as Group A patients. Group B patients were aligned based on the skin markings drawn during VP procedure. CBCTs were taken at the first fraction of treatment and shifts were recorded. RESULTS A total of 60 CBCT images were analyzed for each group of patients. The absolute mean and standard deviations were shown in Table 1. The results indicated that Group A is superior, if not comparable, to Group B. Table 1: The absolute mean and standard deviations of first fraction of CBCT positioning errors for Group A and B patients. CONCLUSION With appropriate ROI, SGRT is a good or superior substitute for plan verification procedure. Localization verification can be done during day one of treatment which ease the pre-treatment workflow to both patients and clinical team. Analysis of customized ROI will be further studied in the future.

Abstract
Objective: To explore the effects of advanced platelet-rich fibrin (A-PRF) on deep partial-thickness burn wounds in nude mice and its mechanism. Methods: The experimental study method was adopted. Forty healthy volunteers in Subei People's Hospital were recruited, including 32 females and 8 males, aged 60 to 72 years. Leukocyte platelet-rich fibrin (L-PRF) and A-PRF membranes were prepared after venous blood was extracted from them. The microstructure of two kinds of platelet-rich fibrin (PRF) membranes was observed by field emission scanning electron microscope. The number of samples was 3 in the following experiments. The L-PRF and A-PRF membranes were divided into L-PRF group and A-PRF group and cultured, and then the release concentrations of platelet-derived growth factor-AB (PDGF-AB) and vascular endothelial growth factor (VEGF) in culture supernatant were determined by enzyme-linked immunosorbent assay on culture day 1, 3, 7, and 14. Mice L929 fibroblasts (Fbs) were divided into L-PRF group and A-PRF group, and cultured with L-PRF or A-PRF conditioned medium, respectively. On culture day 1, 3, and 7, the cell proliferation activity was detected by thiazole blue method. The cell migration rate was detected and calculated at 24 h after scratching by scratch test. Thirty-six male BALB/c nude mice aged 6-8 weeks were selected to make a deep partial-thickness burn wound on one hind leg, and then divided into normal saline group, L-PRF group, and A-PRF group, according to the random number table, with 12 mice in each group. The wounds of nude mice in normal saline group were only washed by normal saline, while the wounds of nude mice in L-PRF group and A-PRF group were covered with the corresponding membranes in addition. The wounds of nude mice in the 3 groups were all bandaged and fixed with dressings. On treatment day 4, 7, and 14, the wound healing was observed and the wound healing rate was calculated. Masson staining was used to observe the new collagen in wound tissue, and immunohistochemical staining was used to detect the percentage of CD31 positive cells in the wound. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, analysis of variance for factorial design, one-way analysis of variance, and least significant difference test. Results: L-PRF membrane's dense network structure was composed of coarse fibrin bundles, with scattered white blood cells and platelets with complete morphology. A-PRF membrane's loose network structure was composed of fine fibrin bundles, with scattered small amount of deformed white blood cells and platelets. On culture day 1, the release concentration of PDGF-AB in PRF culture supernatant in A-PRF group was significantly higher than that in L-PRF group (t=5.73, P<0.05), while the release concentrations of VEGF in PRF culture supernatant in the two groups were similar (P>0.05). On culture day 3, 7, and 14, the release concentrations of PDGF-AB and VEGF in PRF culture supernatant in A-PRF group were significantly higher than those in L-PRF group (with t values of 6.93, 7.45, 5.49, 6.97, 8.97, and 13.64, respectively, P<0.05). On culture day 3, 7, and 14, the release concentrations of PDGF-AB and VEGF in PRF culture supernatant in the two groups were all significantly higher than those in the previous time points within the group (P<0.05). On culture day 1, 3, and 7, the proliferation activity of mice Fbs in A-PRF group was 0.293±0.034, 0.582±0.054, and 0.775±0.040, respectively, which were significantly stronger than 0.117±0.013, 0.390±0.036, and 0.581±0.037 in L-PRF group (with t values of 8.38, 5.14, and 6.16, respectively, P<0.05). At 24 h after scratching, the migration rate of mice Fbs in A-PRF group was (60.9±2.2)%, which was significantly higher than (39.1±2.3)% in L-PRF group (t=11.74, P<0.05). On treatment day 4, the wound exudates of nude mice in L-PRF group and A-PRF group were less with no obvious signs of infection, while the wounds of nude mice in normal saline group showed more exudation. On treatment day 7, the wounds of nude mice in L-PRF group and A-PRF group were dry and crusted, while there was still a small amount of exudate in the wounds of nude mice in normal saline group. On treatment day 14, the wounds of nude mice in A-PRF group tended to heal; a small portion of wounds remained in nude mice in L-PRF group; the wound of nude mice was still covered with eschar in normal saline group. On treatment day 4, 7, and 14, the wound healing rate and percentage of CD31 positive cells of nude mice in L-PRF group were all significantly higher than those in normal saline group (P<0.05); compared with those in normal saline group and L-PRF group, the wound healing rate of nude mice in A-PRF group was significantly increased (P<0.05), the newborn collagen was orderly and evenly distributed, with no excessive deposition, and the percentage of CD31 positive cells was significantly increased (P<0.05). Conclusions: The stable fibrin network structure of A-PRF can maintain the sustained release of growth factors, accelerate cell proliferation, and promote cell migration, so as to shorten the healing time and improve the healing quality of deep partial-thickness burn wounds in nude mice.

Abstract
PURPOSE To investigate the ultrasonographic features in patients with primary uveal mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS Medical records of 12 patients (13 eyes) diagnosed with primary uveal MALT lymphoma between September 2014 and September 2021 were retrospectively reviewed. Ultrasonography, B-scan ultrasonography, color Doppler flow imaging, and ultrasound biomicroscopy findings were retrieved from the medical records. RESULTS Mean age of the included patients was 59.4 ± 8.6 years. Typical ultrasonographic features of the choroidal infiltrates were flat, diffuse, and thickened, with low and homogenous internal reflectivity and with rich arterial blood flow from posterior ciliary arterioles. The mean thickness of the choroidal infiltrates was 1.34 ± 0.68 mm (n = 13). Most of the affected eyes had posterior episcleral extensions, with a mean thickness of 1.66 ± 1.21 mm (n = 12). Typical crescent-like posterior episcleral extensions were detected in nine eyes (69.2%). In six eyes, the blood flow from the choroidal infiltrates communicated with the episcleral extensions. In the ciliary body, the mean thickness of the infiltrates was 1.08 ± 0.43 mm (n = 9), and seven eyes (77.8%) had 360° ring-like infiltrations. The initial best-corrected visual acuity (BCVA) was significantly correlated with the final BCVA after treatment (p < 0.001). CONCLUSION Multipurpose ultrasonographic imaging revealed the unique characteristics of the primary uveal MALT lymphoma and is helpful in the diagnosis of this rare disease.

Abstract
PURPOSE To describe a novel technique for capsular bag reopening and secondary in-the-bag intraocular lens (IOL) implantation in aphakic eyes after vitreoretinal surgery and intraocular tamponade. METHODS We enrolled 14 eyes of 14 patients who underwent primary vitreoretinal surgery with silicone oil tamponade for rhegmatogenous retinal detachment between September 2018 and September 2019. The novel technique was used for capsular bag reopening and foldable single-piece IOL implantation. Patients were followed up at least 24 weeks with routine ophthalmic examinations, corneal endothelial cell density, and IOL tilt and decentration measurement. RESULTS The procedure was successfully completed in 13 cases; in one case, because of posterior capsular tear, the IOL was implanted with ciliary sulcus fixation. After a mean follow-up of 48.8 ± 14.8 (range, 24.9-65.9) weeks, the best-corrected visual acuity (before 20/76 Snellen, 0.63 ± 0.23 logarithm of the minimum angle of resolution equivalent and after 20/35 Snellen, 0.32 ± 0.32 logarithm of the minimum angle of resolution equivalent; P = 0.001) and spherical equivalent (before +8.22 ± 4.08, after -2.39 ± 1.77 D; P < 0.001) improved, intraocular pressure (before 15.93 ± 4.40, after 16.25 ± 4.25 mmHg; P = 0.743) remained unchanged. The IOL was well centered with a mean horizontal and vertical tilt of 0.5070 ± 0.3319° and 0.4652 ± 0.3465°, respectively, and decentration of 0.1705 ± 0.1334 mm and 0.1712 ± 0.1576 mm, respectively. CONCLUSION With this technique, capsular bag reopening and secondary in-the-bag IOL implantation could be achieved in most cases with satisfactory visual outcome and IOL position.

Abstract
BACKGROUND To explore the relationship between the choroid vascular index (CVI) and best corrected visual acuity (BCVA) in a young population with high myopia (HM). SUBJECTS/METHODS Three hundred twenty-six patients with HM were recruited. All subjects underwent a comprehensive ophthalmic examination and enhanced depth imaging optical coherence tomography (EDI-OCT). The horizontal and vertical subfoveal choroidal areas within a 3-mm diameter centred over the fovea were selected. Choroid thickness (ChT), horizontal and vertical total choroidal area (TCAH and TCAV), luminal area (LAH and LAV) and stromal area (SAH and SAV) within the 3-mm diameter were assessed. CVI values (CVIH and CVIV), defined as the ratio of LA to TCA, were also calculated. The correlations among choroid parameters and ocular characteristics were analysed. RESULTS The median age, spherical equivalent (SE) and BCVA were 22.4 years, -10.1 dioptres and 0.099 logMAR, respectively. The ChT was thickest on the temporal and superior sides of the macula and thinnest in the nasal region, with a significant difference. The value of CVIH was significantly greater than that of CVIV because SCAH was smaller than SCAV. Both CVIH and CVIV were closely correlated with BCVA in all patients. CONCLUSIONS The CVI is significantly related to BCVA but is not affected by age, axial length or SE, suggesting that the CVI could be used as an adjunct tool for assessing the visual acuity status in patients with HM.

Abstract
Choroidal neovascularization (CNV) is a severe complication observed in individuals with pathological myopia (PM). Our hypothesis is that specific metabolic alterations occur during the development of CNV in patients with PM. To investigate this, an untargeted metabolomics analysis was conducted using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) on aqueous humor (AH) samples obtained from meticulously matched PM patients, including those with CNV (n = 11) and without CNV (n = 11). The analysis aimed to identify differentially expressed metabolites between the two groups. Furthermore, the discriminative ability of each metabolite was evaluated using the area under the receiver operating characteristic curve (AUC). Enriched metabolic pathways were determined using the KEGG and MetaboAnalyst databases. Our results revealed the detection of 272 metabolites using GC-MS and 1457 metabolites using LC-MS in AH samples. Among them, 97 metabolites exhibited significant differential expression between the CNV and non-CNV groups. Noteworthy candidates, including D-citramalic acid, biphenyl, and isoleucylproline, demonstrated high AUC values ranging from 0.801 to 1, indicating their potential as disease biomarkers. Additionally, all three metabolites showed a strong association with retinal cystoid edema in CNV patients. Furthermore, the study identified 12 altered metabolic pathways, with five of them related to carbohydrate metabolism, suggesting their involvement in the occurrence of myopic CNV. These findings provide possible disease-specific biomarkers of CNV in PM and suggest the role of disturbed carbohydrate metabolism in its pathogenesis. Larger studies are needed to validate these findings.

Abstract
Purpose Proliferative diabetic retinopathy (PDR) is a leading cause of poor vision in young adults. This study sought to evaluate the clinical characteristics and outcomes of primary vitrectomy for PDR in young adults. Patients and Methods Medical data were retrospectively collected at a large ophthalmology hospital in China. We analyzed data for 99 patients (140 eyes) aged <45 years with T1D or T2D who underwent primary vitrectomy for PDR-related complications. Results There were 18 patients with T1D and 81 patients with T2D. The proportion of males was significantly greater than that of females in both groups. The T1D group had a longer duration of diabetes (P = 0.008), younger age at primary vitrectomy (P = 0.049), and lower body mass index (P < 0.001) than the T2D group. The proportion of eyes with rhegmatogenous retinal detachment (RRD) was greater but the proportion of eyes with traction retinal detachment (TRD) was lower in the T1D group than in the T2D group. The final best-corrected visual acuity (BCVA) improved or remained stable in 100% and 85.3% of eyes and decreased in 0% and 14.7% of eyes in the T1D and T2D groups, respectively. After surgery, the incidence of postoperative complications was significant greater in the T2D group than in the T1D group (P = 0.045). Factors influencing the final visual acuity included preoperative BCVA in both groups, the duration of diabetes (P = 0.031) and preoperative FVP (P = 0.004) in the T1D group, and preoperative RRD (P < 0.001) and postoperative NVG (P < 0.001) in the T2D group. Conclusion In this retrospective study, young adults with T2D who underwent vitrectomy had worse final visual acuity and more complications than young adults with T1D.

Abstract
PURPOSE To describe a modified intrascleral fixation technique for repositioning single-piece rigid polymethyl methacrylate intraocular lenses (IOLs). METHODS Four patients with dislocated IOLs were enrolled. Surgical modifications included using ≤1-mm scleral incision for haptic externalization, placing the IOL haptic placement in scleral tunnels, and using 8-0 absorbable sutures. Patients were followed up for 6 months with routine ophthalmic examinations, corneal endothelial cell counts, and ultrasound biomicroscopy (UBM). RESULTS The mean follow-up time was 13.5 ± 5.45 months. The IOL was well centered and the spherical refraction improved (+10.25 ± 2.21 vs. -0.81 ± 1.59 D, P < 0.05), whereas the best-corrected visual acuity (pre 20/43 Snellen, 0.42 ± 0.33 logarithm of the minimum angle of resolution equivalent and post 20/36 Snellen, 0.31 ± 0.22 logarithm of the minimum angle of resolution equivalent; P = 0.235), intraocular pressure (pre 13.8 ± 3.21, post 13.55 ± 5.14 mmHg), corneal endothelium density (pre 2,423.8 ± 279.6/mm 2 , post 2,280.25 ± 350.7/mm 2 ), and total astigmatism (pre -1.94 ± 0.43, post -1.69 ± 0.59 D) remained unchanged. The average horizontal and vertical IOL tilt was 0.33 ± 0.22° and 0.81 ± 0.38°, respectively. Intraocular lens decentration was 0.10 ± 0.03 mm horizontally and 0.13 ± 0.06 mm vertically. CONCLUSION The modified intrascleral fixation technique shows encouraging midterm results in patients with dislocated single-piece, rigid polymethyl methacrylate IOLs. Larger samples and longer follow-up are required to confirm the outcomes of this technique.

Abstract
OBJECTIVE To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD). METHODS We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count. RESULTS The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD. CONCLUSION Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Abstract
BACKGROUND AND OBJECTIVE The current trend of laminoplasty is developing toward the goal of muscle preservation and minimum tissue damage. Given this, muscle-preserving techniques in cervical single-door laminoplasty have been modified with protecting the spinous processes at the sites of C2 and/or C7 muscle attachment and reconstruct the posterior musculature in recent years. To date, no study has reported the effect of preserving the posterior musculature during the reconstruction. The purpose of this study is to quantitatively evaluate the biomechanical effect of multiple modified single-door laminoplasty procedures for restoring stability and reducing response level on the cervical spine. METHODS Different cervical laminoplasty models were established for evaluating kinematics and response simulations based on a detailed finite element (FE) head-neck active model (HNAM), including ① C3 - C7 laminoplasty (LP_C37), ② C3 - C6 laminoplasty with C7 spinous process preservation (LP_C36), ③ C3 laminectomy hybrid decompression with C4 - C6 laminoplasty (LT_C3 + LP_C46) and ④ C3 - C7 laminoplasty with unilateral musculature preservation (LP_C37 + UMP). The laminoplasty model was validated by the global range of motion (ROM) and percentage changes relative to the intact state. The C2 - T1 ROM, axial muscle tensile force, and stress/strain levels of functional spinal units were compared among the different laminoplasty groups. The obtained effects were further analysed by comparison with a review of clinical data on cervical laminoplasty scenarios. RESULTS Analysis of the locations of concentration of muscle load showed that the C2 muscle attachment sustained more tensile loading than the C7 muscle attachment, primarily in flexion-extension (FE) and in lateral bending (LB) and axial rotation (AR), respectively. Simulated results further quantified that LP_C36 primarily produced 10% decreases in LB and AR modes relative to LP_C37. Compared with LP_C36, LT_C3 + LP_C46 resulted in approximately 30% decreases in FE motion; LP C37 + UMP also showed a similar trend. Additionally, when compared to LP_C37, LT_C3 + LP_C46 and LP C37 + UMP reduced the peak stress level at the intervertebral disc by at most 2-fold as well as the peak strain level of the facet joint capsule by 2-3-fold. All these findings were well correlated with the result of clinical studies comparing modified laminoplasty and classic laminoplasty. CONCLUSIONS Modified muscle-preserving laminoplasty is superior to classic laminoplasty due to the biomechanical effect of the posterior musculature reconstruction, with a retained postoperative ROM and loading response levels of the functional spinal units. More motion-sparing is beneficial for increasing cervical stability, which probably accelerates the recovery of postoperative neck movement and reduces the risk of the complication for eventual kyphosis and axial pain. Surgeons are encouraged to make every effort to preserve the attachment of the C2 whenever feasible in laminoplasty.

Abstract
PURPOSE To explore the trend of ocular manifestations and interleukin (IL) during the treatment of vitreoretinal lymphoma (VRL), and to evaluate potential effects of different intravitreal administration schedules on the therapeutic response. DESIGN Interventional comparative non-randomized clinical study. METHODS Patients diagnosed with VRL from January 2011 to January 2022 were included. Intravitreal methotrexate (MTX) injections consisting induction, consolidation and maintenance were scheduled. At baseline and each visit, ocular manifestations and interleukin in aqueous humor were recorded. Effects of the variations (e.g. frequency and number) in the injection schedule on the therapeutic response were analyzed. RESULTS Fifty-eight eyes of 33 patients were treated with intravitreal MTX chemotherapy. A mean (±SD) of 9±3 injections were given; 52 eyes achieved complete remission (CR). IL-10, keratic precipitates and sub-retinal lesions correlated well with the course of treatment (all P <0.001). Initial injection given twice weekly was correlated with a higher rate of CR (36/36) than given once weekly or less frequently (16/22, P=0.011). Ocular progression occurred in 13 eyes of 8 patients. The completion of schedule was correlated with PFS (induction + consolidation + maintenance: 547[335-874] days, induction + consolidation: 355[322-831] days, induction only: 147[116-187.5] days, P<0.001). IL-10 over 50 pg/mL was a feasible threshold for the detection of ocular relapse (sensitivity 100.0%, specificity 95.1%). CONCLUSION Keratic precipitates, sub-retinal lesions and IL-10 could serve as indicators for therapeutic response. Intensive initial administration and adequate injection number would help to improve the response and prognosis. IL-10 over 50 pg/mL could help to detect ocular relapse.

Abstract
OBJECTIVE To investigate the effect of changes in DTX2 expression level on migration and invasion of colorectal cancer (CRC) cells and explore the mechanism. METHODS Two CRC cell lines SW620 and LoVo were transfected with a specific shRNA targeting DTX2 (DTX2-shRNA) or a DTX2-overexpressing plasmid (pcDNA-DTX2), and the transfection efficiency was evaluated with RT-qPCR and Western blotting. Scratch and Transwell assays were used to assess the changes in migration and invasion ability of the transfected cells, and the cellular expression levels of Notch2, NICD, AKT, p-Akt and MMP-2/9 proteins were detected with Western blotting. The CRC cells were co-transfected with pcDNA-DTX2 and Notch2 siRNA to assess the effect of Notch2 knockdown on DTX2 overexpression-induced enhancement of cell migration and invasion. RESULTS The expression levels of DTX2 at both the mRNA and protein levels were significantly decreased in CRC cells transfected with DTX2- shRNA (P < 0.01) and increased in cells transfected with pcDNA-DTX2 (P < 0.01). Scratch and Transwell assays showed that the migration and invasion abilities of CRC cells were significantly lowered following DTX2 knockdown (P < 0.01) and were enhanced in cells with DTX2 overexpression (P < 0.01). The expression levels of Notch2, NICD, p-Akt and MMP-2 proteins decreased significantly in CRC cells with DTX2 knockdown (P < 0.05) and increased obviously in DTX2-overexpressing cells (P < 0.05). In both of the two CRC cell lines, transfection with Notch2 siRNA obviously reversed the effect of DTX2 overexpression in promoting cell migration and invasion (P < 0.01) and expressions of the related proteins. CONCLUSION DTX2 overexpression promotes migration and invasion of CRC cells through the Notch2/Akt axis, suggesting the potential of DTX2 as a new biological indicator of CRC.

Abstract
OBJECTIVE To investigate the efficacy of Bushen Huoxue Fang (BSHXF, a traditional Chinese medicine formula) for improving recurrent spontaneous abortion (RSA) in mice and the role of tyrosine kinase (JAK2) and transcriptional activator (STAT3) signaling pathway in its therapeutic mechanism. METHODS Female CBA/J mice were caged with male DBA/2 mice to establish RSA mouse models, which were randomly divided into model group, dydrogesterone group and BSHXF group, with the female mice caged with male BALB/c mice as the control group (n=6). From the first day of pregnancy, the mice were subjected to daily intragastric administration of BSHXF, dydrogesterone, or distilled water (in control and model groups) for 12 days. After the treatments, serum levels of antithrombin III (AT-III), activated protein C (APC), tissue plasminogen activator (t-PA), progesterone, human chorionic gonadotropin (HCG), and estradiol (E2) were detected in each group using ELISA. HE staining was used to observe the morphological changes of the endometrium of the mice. Western blotting was performed to determine the expressions of p-JAK2, p-Stat3 and Bcl-2 in the placenta of the mice. RESULTS Compared with the control mice, the mouse models of RSA showed a significantly increased embryo loss rate with decreased serum levels of AT-III, T-PA, progesterone, APC and HCG, increased placental expressions of p-JAK2, p-STAT3 and Bax, and decreased expression of Bcl-2 (P < 0.05). Treatments with BSHXF and dydrogesterone both increased serum levels of AT-III, t-PA and HCG in the mouse models; Serum APC level was significantly reduced in BSHXF group and serum progesterone level was significantly increased in dydrogesterone group (P < 0.05). CONCLUSION BSHXF can improve the prethrombotic state and inhibit cell apoptosis by downregulating the JAK2/STAT3 pathway to increase the pregnancy rate in mouse models of RSA.

Abstract
Background Sympathetic ophthalmia (SO) is a rare but sight-threatening uveitis, and most observations have been made after typical manifestations occur. This report focuses on the choroidal changes detected by multimodal imaging at the presymptomatic stage of SO, which is implicated in the early recognition of SO. Case presentation A 21-year-old woman suffered from decreased vision in the right eye and was diagnosed with retinal capillary hemangioblastomas associated with Von Hippel-Lindau syndrome. The patient underwent two 23-G pars plana vitrectomies (PPVs), soon after which typical signs of SO manifested. SO resolved quickly after the oral administration of prednisone and remained stable during the follow-up of more than 1 year. The retrospective analysis revealed preexisting bilaterally increased choroidal thickness, dots of flow void on the choroid, and choriocapillaris en-face slabs in optical coherence tomography angiography (OCTA) after the first PPV, which were all reversed by corticosteroid treatment. Conclusion The case report highlights the involvement of the choroid and choriocapillaris at the presymptomatic stage of SO after the first inciting event. Abnormally thickened choroid and flow void dots suggested that SO had started and an ensuing surgery would run the risk of exacerbating SO. OCTA scanning of both eyes should be ordered routinely for patients with a history of trauma or intraocular surgeries, especially before the next surgical intervention. The report also suggests that non-human leukocyte antigen gene variation may also regulate the progression of SO, which requires further laboratory investigations.

Abstract
Low back pain (LBP) is an extremely common disorder and is a major cause of disability globally. Intervertebral disc degeneration (IVDD) is the main contributor to LBP. Nevertheless, the specific mechanisms underlying the pathogenesis of IVDD remain unclear. Mitochondria are highly dynamic organelles that continuously undergo fusion and fission, known as mitochondrial dynamics. Accumulating evidence has revealed that aberrantly activated mitochondrial fission leads to mitochondrial fragmentation and dysfunction, which are involved in the development and progression of IVDD. To date, research into mitochondrial dynamics in IVDD is at an early stage. The present narrative review aims to summarize the most recent findings about the role of mitochondrial fission in the pathogenesis of IVDD.

Abstract
PURPOSE Anaplastic thyroid cancer (ATC) is a rare and lethal malignant cancer. In recent years, the application of molecular-driven targeted therapy and immunotherapy has markedly improved the prognosis of ATC. This study aimed to identify characteristic genes for ATC diagnosis and revealed the role of ATC characteristic genes in drug sensitivity and immune cell infiltration. METHODS We downloaded ATC RNA-sequencing data from the GEO database. Following the combination and normalization of the dataset, we first divided the combined datasets into the training cohort and the validation cohort. We identified differentially expressed genes (DEGs) in ATC by differential expression analysis in the training cohort. We used two machine learning algorithms, least absolute shrinkage and selection operator (LASSO) and support vector machine-recursive feature elimination (SVM-RFE) to identify ATC characteristic genes. The CIBERSORT algorithm was performed to calculate the abundance of various immune cells in ATC. Finally, we validated the expression of ATC characteristic genes by quantitative RT-PCR (RT-qPCR) in ATC cell lines and immunohistochemistry (IHC). RESULTS A total of 425 DEGs were identified in the training cohort, including 240 upregulated genes and 185 downregulated genes. Four ATC characteristic genes (ADM, PXDN, MMP1, and TFF3) were identified, and their diagnostic value was validated in the validation cohort (AUC in ROC analysis > 0.75). We established a practical gene expression-based nomogram to accurately predict the probability of ATC. We also found that ATC characteristic biomarkers are associated with the tumor immune microenvironment and drug sensitivity. CONCLUSION ADM, PXDN, MMP1, and TFF3 might serve as potential ATC diagnostic biomarkers and may be helpful for ATC molecular targeted therapy and immunotherapy.

Abstract
Purpose Pathologic myopia (PM) is one of the primary causes of blindness. This study aims to explore the possible relations between the composition of microRNA in vitreous exosomes of patients with PM and the progression of myopic maculopathy. Methods Vitreous humor (VH) samples were collected from patients undergoing retinal surgery. A total of 15 and 12 VH samples were obtained from patients with PM and control, respectively. The PM group was divided into PM-L (G2) and PM-H groups (G3 and G4) in order to explore differentially expressed microRNAs (DEMs) that account for the relatively poor prognosis in G3 and G4 myopic maculopathy. A Weighted Gene Co-Expression Network Analysis (WGCNA) was conducted to find the persistently altered key microRNAs in myopic maculopathy progression. The Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment analysis were used. Results High purity exosomes were extracted from the vitreous fluid of patients with PM and control. The top five downregulated DEMs of PM-H versus PM-L can reflect the tendency of deterioration of PM-H myopic maculopathy. MiR-143-3p and miR-145-5p, which were found in WGCNA, may participate in the development of myopic maculopathy. These microRNAs all relate to the insulin resistance pathway. Conclusions This is the first study to explore the relations between the progression of myopic maculopathy and vitreous exosomal microRNAs. Vitreous exosomal miR-143-3p and miR-145-5p can be considered biomarkers for patients with PM, and the vitreous exosomal DEM associated with PM-H may represent alarming signals of myopic maculopathy deterioration.

Abstract
Background To determine the anti-inflammatory effects of IMD-0354, a specific NF-κB blocker, on glial cells in rats with streptozotocin (STZ)-induced diabetic retinopathy (DR). Methods The following four groups of rats were used: control, control + IMD-0354, STZ, and STZ + IMD-0354. After six weeks of STZ injection, diabetic rats and nondiabetic control rats received IMD-0354 (30 mg/kg) or an equal volume of 4% dimethyl sulfoxide (DMSO) in phosphate-buffered saline intraperitoneally for six consecutive weeks. The following four groups of primary rat retinal microglia and Müller cells were used: control (5 mM), control + IMD-0354, high glucose (20 mM), and high glucose + IMD-0354. The effects of IMD-0354 on nuclear factor-κB (NF-κB) activation, oxidative stress strength, expression of inflammatory cytokines and VEGF (vascular endothelial growth factor), activation of glial cells, and apoptosis of neuron cells were evaluated by immunohistochemistry, oxidative stress assays, western blot, enzyme linked immunosorbent assay (ELISA) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining respectively. Results Nuclear translocation of NF-κB was markedly increased in diabetic rat retina and high glucose treated glial cells. Systemic administration of IMD-0354 significantly inhibited NF-κB activation in both diabetic rat retina and high glucose treated glial cells, ameliorated oxidative injury, inflammatory responses, VEGF production and glial cell activation, and protected neurons from apoptosis. Conclusions Our findings indicated that NF-κB activation is acritical step in the abnormal reactivity of glial cells in STZ-induced diabetic rats. Inhibition effect of IMD-0354 on NF-κB activation may represent a promising therapeutic strategy for DR via a variety of mechanisms, including inflammation reduction and glial cells regulation.

Abstract
OBJECTIVES The aim of this study was to determine the association between oral health and the development of frailty over a 10-year period in older Chinese adults. DESIGN This was a cohort study. SETTING AND PARTICIPANTS The data in this study were derived from the 2008, 2011, 2014 and 2018 waves of the Chinese Longitudinal Health Longevity Survey (CLHLS). The final analysis included 1155 older adults who had complete data for the Frailty Index (FI) and the other factors(oral health, sociodemographics, etc) that were analyzed in the study. MEASUREMENTS Frailty was assessed by the FI, which consists of 40 deficits(self-health assessments, diseases, physical functions,etc). Multivariable logistic regression was carried out to calculate the odds ratios (ORs) of the independent variables,which were obtained from investigator surveys and self-reports, in association with the development of frailty. RESULTS The prevalence of frailty at baseline was 22.94%, and the 10-year incidence of frailty was 24.16% (215/890). Age, number of natural teeth, use of dentures, toothache and sex were independent risk factors for frailty at baseline. After full adjustment, multivariate logistic regression analysis indicated that compared with having ≥21 teeth, edentulism (ORs 3.575; 95% CI 2.095,6.101) and partial tooth loss (ORs 2.448; 95% CI 1.592,3.766) were associated with progression to frailty. Compared with those with ≥21 teeth, those with <21 teeth and without dentures (ORs 2.617; 95% CI 1.713,3.999) were more likely to progress to frailty. CONCLUSION The loss of natural teeth is associated with the progression of frailty in older Chinese adults and denture using can help lower the odds of being frailty. Further research on maintain natural teeth and the appropriate use of dentures may help to establish effective frailty prevention strategies for the older adults.

Abstract
PURPOSE Proliferative diabetic retinopathy (PDR) is a leading vision-threatening disease. In this study, we investigated the clinical features of PDR and the surgical outcomes of its complications in patients with type 2 diabetes (T2D). PATIENTS AND METHODS We retrospectively reviewed the medical data of patients with T2D who underwent vitrectomy for PDR between January 2016 and June 2021. The patients were divided into two groups by age (young patients, < 45 years; older patients, ≥ 45 years). RESULTS There were 149 eyes (100 patients) in the young patient group and 315 eyes (256 patients) in the older patient group. The proportion of males and the proportion of patients requiring binocular surgery were much higher in the young patient group than in the older patient group (P = 0.005 and P < 0.001, respectively). In the young patient group, 26.2% of eyes had active fibrovascular proliferation compared with only 11.4% in the older patient group (P < 0.001). The final best-corrected visual acuity (BCVA) was significantly improved relative to the preoperative BCVA in both groups (P < 0.001). After surgery, there were no significant differences in the incidence of postoperative neovascular glaucoma (NVG) or recurrent vitreous hemorrhage (VH) between the two groups. The incidence of postoperative recurrent retinal detachment was higher in the young patient group (P = 0.033). The risk factors associated with the visual outcomes in the young patient group included preoperative BCVA (P < 0.001), renal diseases (P = 0.001), postoperative NVG (P < 0.001), and recurrent VH (P = 0.028). CONCLUSION In this retrospective study, young patients who underwent vitrectomy for PDR had more severe clinical characteristics before vitrectomy. However, vitrectomy (combined with cataract surgery when necessary) achieved better final visual outcomes in young patients than in older patients with T2D.

Abstract
Purpose To compare ultrasound biomicroscopy (UBM), Coulter counter, and B-scan ultrasonography in the evaluation of silicone oil (SO) emulsification. Methods Patients who underwent primary pars plana vitrectomy with SO tamponade for rhegmatogenous retinal detachment and SO removal were included. UBM images were acquired before the SO removal, and B-scan images were taken after removal. The number of droplets in the first and last 2 mL of washout fluid was analyzed using a Coulter counter. The correlations between these measurements were analyzed. Results Thirty-four eyes received both UBM and Coulter counter analysis for the first 2 mL of washout fluid, and 34 underwent B-scan and Coulter counter analysis of the last 2 mL washout fluid. The mean UBM grading was 26.41 ± 9.71 (range: 1-36); the mean SO index obtained with B-scan was 5.25 ± 5.00% (range: 0.10-16.49%), and the mean number of SO droplets was 1.26 ± 2.45 × 107/mL and 3.34 ± 4.22 × 106/mL in the first and last 2 mL of washout fluid, respectively. There were significant correlations between UBM grading and SO droplets in the first 2 mL and between B-scan grading and SO droplets in the last 2 mL (all P < 0.05). Conclusions UBM, Coulter counter, and B-scan ultrasonography could all be used in the evaluation of SO emulsification, and their findings were comparable.

Abstract
Objective: To investigate the trend of postoperative cavity status in patients with eosinophilic chronic sinusitis with nasal polyps (eCRSwNP) who underwent total nasalization surgery and partial reboot surgery. And to discuss the relationship between tissue eosinophil counts and status of postoperative cavity. Methods: Patients with eCRSwNP in four tertiary medical centers (Longgang ENT Hospital, Xiamen Humanity Hospital, Guangdong Clifford Hospital and the First Affiliated Hospital of Sun Yat-Sen University) from March 2018 to October 2021 were divided into 2 groups. The group without previous surgery history was performed for the nasalization surgery, and another group with previous surgery history underwent the part-reboot surgery. The follow-up time after operation was defined as the following 5 stages: 6, 12, 20-24, 36 and more than 42 months. According to FESS-95 Guangzhou standard, status of sinus cavity was assessed and classified into 3 categories: good, better and bad. The association between the sinus cavity status and tissue eosinophil counts in the above 5 stages was analyzed by one-way ANOVA, and P<0.05 was considered statistically significant. Results: A total of 72 eCRSwNP patients finished the follow-up in this study. There were 47 males and 25 females in these patients, aged from 11 to 67 years. A total of 50 cases underwent nasalization surgery and 22 cases underwent partial reboot surgery. With the follow-up time from 6 to 48 months, there were 72 cases (100.0%) who completed 6 months and 12 months follow up, 46 cases (63.9%) for 20-24 months, 36 cases (50.0%) for 32-36 months and 16 cases (22.2%) with the follow-up time more than 42 months. No matter what kind of surgery, there was no "bad" situation of the surgical cavity status 6 months after the operation, and the differentiation gradually occurred more than 12 months after the surgery. Moreover, the rates of "good" cavity status for the 5 stages in the group of nasalization surgery were 78.0%, 66.0%, 56.7%, 47.6% and 42.9%, and were 63.6%, 45.5%, 25.0%, 20.0% and 11.1% in the partial reboot surgery group, respectively, suggesting that the status of nasal cavity in nasalization surgery group was always better than that in partial reboot surgery group in every period. In addition, the "bad" rate was 0, 8.0%, 10.0%, 14.3% and 28.6% in the group of nasalization surgery, and was 0, 27.3%, 18.8%, 33.3% and 55.6% in the partial reboot surgery group, respectively. The average percentage of tissue eosinophil counts in the 72 cases was 42.1%, which had no obvious effect on the status of the surgical cavity (P>0.05). Conclusions: For eCRSwNP patients, the operative cavity status in the patients without previous operation history treated with nasalization surgery is good. The time of 1-2 years after surgery is the main period for sinus lesions. The counts of tissue eosinophils has no significant influence on surgical sinus cavity status in the eCRSwNP patients.

Abstract
Purpose Retinitis pigmentosa (RP) is a heterogeneous group of inherited disorders characterized by photoreceptor degeneration. The rhodopsin gene (RHO) is the most frequent cause of autosomal dominant RP (ADRP), yet it remains unclear how RHO mutations cause heterogeneous phenotypes. Energy failure is a main cause of the secondary cone death during RP progression; however, its role in primary rod death induced by ADRP RHO mutants is unknown. Methods Three RHO missense mutations were chosen from different clinical classes. Wild-type (WT) RHO and its mutants, P23H (class B1), R135L (class A), and G188R (class B2), were overexpressed in 661w cells, a mouse photoreceptor cell line, and their effects on oxidative phosphorylation (OXPHOS) and aerobic glycolysis were compared separately. Results Here, we report that energy failure is an early event in the cell death caused by overexpression of WT RHO and its mutants. RHO overexpression leads to OXPHOS deficiency, which might be a result of mitochondrial loss. Nonetheless, only in WT RHO and P23H groups, energy stress triggers AMP-activated protein kinase activation and metabolic reprogramming to increase glycolysis. Metabolic reprogramming impairment in R135L and G188R groups might be the reason why energy failure and cell injury are much more severe in those groups. Conclusions Our results imply that overexpression of RHO missense mutants have distinct impacts on the two energy metabolic pathways, which might be related to their heterogeneous phenotypes.

Abstract
The present study aimed to investigate the level of translocator protein (TSPO) and its correlation with different inflammatory cytokines in diabetic retinopathy (DR) patients. Peripheral blood samples were obtained from 54 DR patients and 22 age-related cataract (ARC) patients. The mRNA expression of TSPO, voltage-dependent anion channel (VDAC), apoptosis-associated speck like protein with a caspase recruitment domain (ASC), NOD-like receptors pyrin domain-containing 3 (NLRP3) and caspase-1 were examined by reverse transcription-quantitative PCR. Interleukin-1β and interleukin-18 levels were detected by enzyme-linked immunosorbent assay. The mRNA levels of TSPO, VDAC, ASC, NLRP3 and capase-1, the protein levels of IL-β and IL-18 were all significantly higher in the DR group compared with those in the ARC group. The expression levels of those aforementioned cytokines/proteins were more significantly higher in the subgroup of active proliferative DR (PDR) compared with those in the inactive PDR group (P<0.05). Significant positive correlations between TSPO/VDAC complex and ASC, NLRP3, capase-1, IL-β and IL-18 were found in DR patients. These outcomes suggested that TSPO/VDAC complex and NLRP3 inflammasomes may play an important role in the development and progression of DR.

Abstract
Abstract
Background
To investigate the optical coherence tomography angiography (OCTA) characteristics of diabetic macular edema (DME) at different stages.
Methods
This study was a cross-sectional study. Patients diagnosed with DME were recruited. DME was classified into early, advanced, and severe DME. The vessel density (VD) in the superficial vascular plexus (SVP), deep vascular plexus (DVP) and foveal avascular zone (FAZ) parameters, including FAZ area, FAZ perimeter, acircularity index and foveal VD in a 300-μm-wide region around the FAZ (FD-300), were calculated by the AngioVue software. A multivariate generalized estimating equation was used to evaluate the associations between visual acuity and OCTA metrics.
Results
Ninety-two eyes from 74 patients with DME were included in this study. Compared to early (P = 0.006) and advanced DME (P = 0.003), the acircularity index was higher in severe DME. Both whole and parafoveal VD in the DVP decreased in eyes with severe DME compared to early DME (P = 0.018, P = 0.005, respectively) and advanced DME (P = 0.035, P = 0.012, respectively). In the multivariate generalized estimating equation, DME severity, FAZ area and foveal thickness were positively associated with worse visual acuity (P = 0.001, P = 0.007 and P = 0.001, respectively).
Conclusion
Compared to early and advanced DME, severe DME showed increased irregularity in the FAZ and more extensive vessel damage in the DVP. Greater severity level of DME, larger FAZ area, and increased foveal thickness could be risk factors for poor visual acuity.
Trial registration The protocol was published in the Chinese Clinical Trial Registry (ChiCTR2000033082).

Abstract
With the promotion of mass COVID-19 vaccination in the elimination of the SARS-CoV-2 pandemic, new side effects, including ocular complications, are emerging. In this study, we report on a 62-year-old Chinese man who developed Vogt-Koyanagi-Harada (VKH) disease six days after his third dose of an inactivated COVID-19 vaccine, with a preceding severe headache and tinnitus. His medical history included tuberculosis 20 years prior and hypertension. Systemic prednisone was administered, resulting in completely relieved inflammation and improved visual acuity. Another three and a half months later, the visual acuity of his right eye slightly decreased due to complicated central serous chorioretinopathy (CSC) disease. By gradually replacing prednisone with cyclosporine within 2 months, the subretinal fluid was completely absorbed at the last visit. Steroid-related CSC during the treatment course of VKH disease after COVID-19 vaccination has never been reported before. By reviewing relative literature, we discuss the mechanism of CSC onset in our case and the potential therapeutic strategies. Complicated CSC may develop in the eyes with vaccine-related VKH after steroid treatment. Ophthalmologists should be aware of this condition, carefully distinguish complicated CSC with inflammation relapse, and adjust the medication in a timely manner.

Abstract
BACKGROUND Oxidative stress-caused damage to the retinal pigment epithelium (RPE) underlies the onset and progression of age-related macular degeneration (AMD). Impaired mitochondrial biogenesis sensitizes RPE cells to mitochondrial dysfunction, energy insufficiency and death. Src-homology 2 domain-containing phosphatase (SHP)-1 is important in regulating immune responses and cell survival. However, its roles in cell survival are not always consistent. Until now, the effects of SHP-1 on RPE dysfunction, especially mitochondrial homeostasis, remain to be elucidated. We sought to clarify the effects of SHP-1 in RPE cells in response to atRAL-induced oxidative stress and determine the regulatory mechanisms involved. METHODS In the all trans retinal (atRAL)-induced oxidative stress model, we used the vector of lentivirus to knockdown the expression of SHP-1 in ARPE-19 cells. CCK-8 assay, Annexin V/PI staining and JC-1 staining were utilized to determine the cell viability, cell apoptosis and mitochondrial membrane potential. We also used immunoprecipitation to examine the ubiquitination modification of stimulator of interferon genes (STING) and its interaction with SHP-1. The expression levels of mitochondrial marker, proteins related to mitochondrial biogenesis, and signaling molecules involved were examined by western blotting analysis. RESULTS We found that SHP-1 knockdown predisposed RPE cells to apoptosis, aggravated mitochondrial damage, and repressed mitochondrial biogenesis after treatment with atRAL. Immunofluoresent staining and immunoprecipitation analysis confirmed that SHP-1 interacted with the endoplasmic reticulum-resident STING and suppressed K63-linked ubiquitination and activation of STING. Inhibition of STING with the specific antagonist H151 attenuated the effects of SHP-1 knockdown on mitochondrial biogenesis and oxidative damage. The adenosine monophosphate-activated protein kinase (AMPK) pathway acted as the crucial downstream target of STING and was involved in the regulatory processes. CONCLUSIONS These findings suggest that SHP-1 knockdown potentiates STING overactivation and represses mitochondrial biogenesis and cell survival, at least in part by blocking the AMPK pathway in RPE cells. Therefore, restoring mitochondrial health by regulating SHP-1 in RPE cells may be a potential therapeutic strategy for degenerative retinal diseases including AMD.

Abstract
OBJECTIVES To investigate the threshold thickness of the foveal outer nuclear layer (ONL) associated with favourable visual outcome after half-dose photodynamic therapy (PDT) in patients with central serous chorioretinopathy (CSC). METHODS The CSC patients were divided into two groups according to whether their best-corrected visual acuity (BCVA) at 1 year after half-dose PDT was 20/20 or worse than 20/20. Three multivariable logistic regression models were respectively created to determine the prognostic value of the pre-PDT foveal ONL thickness, the pre- and the post-PDT foveal ONL thickness ratio, which was defined as the foveal ONL thickness in the CSC eye to that in the normal contralateral eye, for predicting the outcome of half-dose PDT. The areas under the receiver operating characteristic curves (AUCs) were compared and the best cut-off values were determined, respectively. RESULTS Totally, 134 patients were included. The pre-PDT foveal ONL thickness, the pre-PDT and the post-PDT foveal ONL thickness ratios were all independent predictors of the outcome after half-dose PDT in their respective model (all P < 0.05). The AUC of the post-PDT foveal ONL thickness ratio was significantly higher than the AUCs of the other two parameters (0.940 vs 0.840 and 0.882, DeLong test: both P < 0.05), with the cut-off value of 0.81. CONCLUSIONS The threshold of the foveal ONL thickness ratio is 0.81. Active CSC eyes with a foveal ONL thickness ratio of 0.81 or more could probably retain BCVA of 20/20 after half-dose PDT. They were considered reasonable to wait for spontaneous resolution of sub-retinal fluid.

Abstract
OBJECTIVE To explore the presence of residual emulsified silicone oil (SO) droplets in patients with rhegmatogenous retinal detachment (RRD) and their possible risk factors. METHODS Patients who underwent primary pars plana vitrectomy with SO injection for RRD and SO removal at the same eye centre were included. Approximately 10 weeks after SO removal, B-scan ultrasonography was performed, and using ImageJ, the silicone oil index (SOI) was measured, and its possible correlations with other clinical factors were explored. RESULTS A total of 101 eyes were included. Residual SO particles were found in all the patients (100%), and the mean SOI was 4.04% ± 5.16% (range 0.06%-19.88%). Multiple linear regression revealed that, among all the clinical factors, axial length (AL) and ocular hypertension (intraocular pressure (IOP) > 21 mmHg or the use of antiglaucoma medications) before SO removal were positively and significantly associated with the SOI (all P < 0.05). Patients with ocular hypertension after SO removal had a higher SOI, a longer SO duration, a higher IOP before SO removal and a longer AL than those without (all P < 0.05). CONCLUSIONS Patients with a larger AL and higher IOP before SO removal were more prone to have more residual SO droplets, which might in turn lead to an elevated IOP. In these eyes, thorough irrigation or repeated fluid-air exchange might be necessary.

Abstract
The axons of retinal ganglion cells (RGCs) pass through the optic nerve head (ONH) and form the optic nerve (ON). The ONH serves as an anatomical interface between the vitreous cavity and subarachnoid space. After inducing acute neuroinflammation by intravitreal injection of lipopolysaccharides (LPS), we observed inflammatory activation in the retina, but detect no signs of inflammation in the posterior ON or infiltration of inflammatory cells in the ONH. Therefore, we hypothesized that the ONH functions as a barrier to vitreous inflammation. Using transmission electron microscopy, we identified significant increase in G-ratio in the posterior ON on day 7 post intravitreal injection (PII) of LPS compared with the phosphate buffered saline (PBS) group. Moreover, using confocal imaging of ex vivo tissue extracted from Aldh1L1-eGFP reporter mice, we observed that the ONH astrocytes altered their spatial orientation by elongating their morphology along the axonal axis of RGCs in LPS- versus PBS-treated eyes; this was quantified by the ratio of longitudinal (DL) and transverse (DT) diameter of astrocytes and the proportion of longitudinally locating astrocytes. Supportive evidences were further provided by transmission electron microscopic imaging in rat ONH. We further conducted RNA sequencing of ONH on day 1 PII and found LPS induced clear upregulation of immune and inflammatory pathways. Furthermore, gene set enrichment analysis revealed that astrocyte and microglia contributed prominently to the transcriptomic alterations in ONH. Here, we report that the vitreous infectious insults induce morphological changes of ONH astrocytes and transcriptomic alterations in the ONH. Glial responses in the ONH may defend against vitreous infectious insults and serve as a barrier to inflammation for the central nervous system.

Abstract
In this study, we aimed to investigate whether chronic retinal inflammation is involved in the pathogenesis of form-deprivation myopia (FDM) using tree shrews as an animal model. Twenty-one tree shrews were randomly divided into 7-day/14-day FDM (FDM7/FDM14) groups and their corresponding 7-day/14-day control groups. Refraction and axial length were measured. To determine the effects of form deprivation on inflammation, we used real-time polymerase chain reaction (PCR) and immunohistochemistry to assess the expression levels of several proinflammatory cytokines. At day 0, the eyes in the FDM and control groups were hyperopic. However, after 7 and 14 days of form deprivation, the refractive error of the eyes in the FDM7 and FDM14 groups shifted from +6.6 ± 0.3 diopters (D) to +4.0 ± 0.5 D and from +6.4 ± 0.3 D to +5.0 ± 0.3 D, respectively. The levels of tumor necrosis factor-α, interleukin (IL)-6, IL-8, monocyte chemoattractant protein-1, and nuclear factor κB were increased in the FDM eyes, compared with those in the control eyes. The increase in matrix metalloproteinase-2 expression was greater in the FDM eyes than in the contralateral and control eyes, whereas collagen type I expression was downregulated. In conclusion, chronic inflammation may play a crucial pathogenic role in form-deprivation myopia in tree shrews.

Abstract
Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.
