Central serous chorioretinopathy(CSC), the first described pachychoroid disease, is characterized by visual distortions and loss of vision, which are commonly seen in middle-aged male. Research has demonstrated that ocular blood flow in CSC is in a state of overload, characterized by the dilation of vortex vein ampullae and choroidal vasculature. The obstruction of venous outflow is linked to scleral thickness, while the choriocapillaris exhibits perfusion deficits due to compression from the engorged vascular layer. Over time, vascular remodeling occurs, with venous anastomoses forming to create alternative drainage pathways and mitigate blood stasis. These abnormalities in vortex vein dynamics and choroidal circulation play a critical role in elucidating the underlying pathogenesis and clinical manifestations of CSC. This review highlights the alterations in vortex vein and choroidal vasculature in CSC, hoping to understand how the changes of blood flow affect the course of CSC and their correlation with treatment response. By evaluating blood flow dynamics, we aim to determine the disease stage more accurately, optimize therapeutic strategies, and ultimately enhance patient outcomes.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

BACKGROUND:Studies have shown that both Panax notoginseng saponins and concentrated growth factor can promote fracture healing,but there are few studies addressing their combined effects on fracture healing.Panax notoginseng saponins may accelerate fracture healing by promoting the release of concentrated growth factor-related factors over a certain period of time. OBJECTIVE:To study the effect of Panax notoginseng saponins on concentrated growth factor release and fracture healing in rats. METHODS:Eighteen 8-week-old Sprague-Dawley rats were numbered and randomly divided into three groups:Panax notoginseng saponins group,model control group and blank group.Panax notoginseng saponins group was fed with Panax notoginseng saponins for 2 weeks.Model control group was given 2 mL of normal saline for 2 weeks and blank group was fed normally.Concentrated growth factor was obtained by the centrifugation method both from the Panax notoginseng saponins group and model control group.After 1 week of normal feeding,all animals underwent modeling for femoral fracture.The Panax notoginseng saponins group and the model control group were implanted with autologous concentrated growth factor,and then the release concentration of growth factors at different time points(1 hour,1,3,5,7,9 and 11 days)were measured by ELISA.Fracture healing was assessed based on postoperative X-ray and hematoxylin-eosin staining of bone tissues. RESULTS AND CONCLUSION:Compared with the model control group,the Panax notoginseng saponins group had higher release concentrations of vascular endothelial growth factor A and transforming growth factor β at 7,9,and 11 days,Platelet-derived growth factor BB at 5,9,and 11 days,and basic fibroblast growth factor at 1-11 days(P<0.01).X-ray examinations indicated that fracture healing in the Panax notoginseng saponins group was better than that in the model control group,and fracture healing in these two groups was better than that in the blank group at 2 months after surgery.Hematoxylin-eosin staining results found that the constituent osteocyte density in the Panax notoginseng saponins group was greater than that in the model control group,and the constituent osteocyte density in these two groups was better than that in the blank group.These findings indicate that Panax notoginseng saponins can increase the concentration of concentrated growth factor-related factors.After intervention with Panax notoginseng saponins,concentrated growth factors are more advantageous in promoting fracture healing in rats.

Objective:To understand the epidemiological characteristics and trends of injury in older adults in Jiangsu Province from 2006 to 2022 and provide a scientific basis for developing prevention and control measures.Methods:The data on injury cases aged 60 and older were collected from 12 sentinel hospitals in Jiangsu Province during 2006-2022. The study analyzed the proportion of injury cases among the elderly in the overall population and calculated the annual percent change and average annual percent change (AAPC). A pairwise comparison between groups was performed, and the differences were judged according to the adjusted standardized residuals.Results:From 2006 to 2022, there were 218 426 injury cases among individuals aged 60 and older in Jiangsu Province, which accounted for an increasing proportion of injury cases within the entire population (AAPC=3.17%, P<0.001). The first five causes of elderly injury were falls (42.06%), road traffic injuries (20.20%), animal injuries (11.45%), knife/sharp injuries (9.43%), and blunt injuries (8.13%). From 2006 to 2022, the proportion of falls, animal injuries, and knife/sharp injuries among the elderly aged ≥60 showed an increasing trend, while the proportion of road traffic injuries and blunt injuries decreased (all P<0.001). The incidence of injury was highest in October, with a daily incidence peak between 8:00 and 10:00. Leisure activities (40.34%) were the major activity leading to injury. The injury occurred mainly at home (53.74%), and the injury intention was mainly unintentional (97.41%), all of which showed an increasing trend ( P<0.001). The injuries were mainly bruises (36.00%), and the most common injured positions of the body were low limbs (27.55%), all of which showed a decreasing trend ( P<0.001). About 69.80% of cases were slight, and 79.38% were discharged after treatment, which showed an increasing trend ( P<0.001). Conclusions:The injury data for individuals aged 60 and older in Jiangsu Province exhibited varying trends from 2006 to 2022. There was a noticeable increase in the proportion of elderly injury cases within the overall injury population, as well as an upward trend in falls, animal injuries, and knife/sharp injuries as leading causes of injury. It is imperative to actively develop prevention measures based on the epidemiological characteristics and evolving trends of elderly injuries in Jiangsu Province.

Objective: To evaluate the efficacy and safety of Jiawei Simiao powder (JWSMP) combined with celecoxib for the treatment of acute gouty arthritis by conducting a meta-analysis of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases, Chinese Scientific Journal Database, Wanfang, Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched from inception until December 2023. Continuous variables were analyzed using the mean difference (MD) for analysis, and dichotomous variables were used as risk ratios. Data with similar characteristics were pooled for meta-analysis, and heterogeneity was assessed using I2. The Cochrane Handbook was used to assess the risk of bias and quality. RevMan 5.3 software was used to perform the meta-analysis. Results: Thirteen RCTs involving 1007 patients were included in the study. The quality of the included studies was low (unclear randomization processes and insufficient blinding reporting). The group receiving JWSMP combined with celecoxib showed significantly lower levels of serum uric acid (SUA, MD = −66.32, 95% confidence interval (CI): −80.97 to −51.67, P < .001), erythrocyte sedimentation rate (ESR, MD = −6.05, 95% CI: −8.29 to −3.82, P < .001), C-reactive protein (CRP, MD = −7.39, 95% CI: −11.15, −3.63, P < .001), and joint pain score (VAS score, MD = −2.14, 95% CI: −2.4 to −1.88, P < .001) compared to celecoxib alone. Additionally, the JWSMP combined group had a higher total effective rate (risk ratio = 1.22, 95% CI: 1.14 to 1.29, P < .001) and fewer adverse compared to celecoxib alone. Conclusions JWSMP combined with celecoxib is more effective than celecoxib alone in improving the total efficacy rate, alleviating joint pain, and improving SUA, ESR, and CRP levels. JWSMP also reduced the occurrence of adverse events caused by celecoxib. However, the quality of the included studies was low, highlighting the need for further high-quality research with larger sample sizes and robust methodologies, such as double-blind randomization, to confirm these findings.

Objective:To discuss the association between occupational acid fog exposure and accelerated biological aging of the workers,and to clarify its related risk factors.Methods:A total of 341 male workers exposed to occupational acid fog and 201 male workers without occupational exposure were selected as the study subjects,and they were divided into exposure group and control group,respectively.The general informations of the subjects in two groups were collected through questionnaires and physical examinations.The levels of red blood cell count(RBC),platelet count(PLT),albumin(ALB),urea(Urea),creatinine(CR),triglycerides(TG),total cholesterol(TC),glycated hemoglobin(HBA1c),and high-sensitivity C-reactive protein(Hs-CRP)in serum of the subjects in two groups were detected.The Klemera-Doubal method(KDM)was used to construct the composite aging measure,KDM-biological age(BA)(KDM-BA).The model parameters were trained using samples from the 2009 China Health and Nutrition Survey(CHNS)Database to calculate the BA acceleration of the subjects in two groups;stratified analysis based on the population characteristics was conducted to analyze the BA of the subjects in two groups with different population characteristics;generalized linear model was used to analyze the factors influencing BA acceleration due to acid fog exposure.Results:The model parameters were trained using samples from the 2009 CHNS Database,including 8 133 cases aged 20-79 years,of which 3 788 were male.The levels of Urea,CR,HBA1c,ALB,and TC,as well as systolic blood pressure(SBP),total working years,sleep duration,and body mass index(BMI)of the subjects between two groups had significant differences(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05).In entire population and exposure group,the BA acceleration in the smokers was significantly higher than that in the non-smokers(P<0.05).In entire population,control group,and exposure group,the BA accelerations of the subjects in different BMI groups were significantly decreased with the increase of BMI(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05),including those under 40 years old,with total working years of 4-7 years,Han nationality,unmarried,smokers,and sleep duration 6-7 h,and with overweight.Acid fog exposure,smoking,and BMI were associated with the BA acceleration(β=0.72,95%CI:0.24-1.21;β=0.59,95%CI:0.11-1.06;β=-0.29,95%CI:-0.35—-0.22).Conclusion:Occupational acid fog exposure may accelerate the biological aging in the workers,and acid fog is a risk factor to accelerate the biological aging of the body.

Objective: To investigate the mechanism of vascular endothelial growth factor(VEGF) inducing tolerogenic dendritic cells(DCs) in oral squamous cell carcinoma (OSCC). Methods: The DCs were divided into four groups: Control group (DC), VEGF group (VEGF added into DC), Co-culture group (DC co-cultured with SCC7) and Anti-VEGF group (anti-VEGF antibody added into DC co-cultured with SCC7). Flow cytometry (FCM) was used to detect DC surface markers. To detect the effect of DC on proliferation activity of T lymphocyte, the experiment included five groups: Nc group (T lymphocyte), Control group (T lymphocyte added into DC), VEGF group (T lymphocyte + DC + VEGF), Co-culture group (T lymphocyte + DC + supernatant of SCC7) and Anti-VEGF group (T lymphocyte + DC + supernatant of SCC7 + anti-VEGF antibody). Subsequently, the mixed lymphocyte reaction(MLR) was conducted. The expression levels of indole-2, 3-doxygenase(IDO)and programmed cell death 1 ligand 1(PD-L1)in DC were detected by western blot, real time PCR and FCM respectively. For the cytotoxic lymphocyte (CTL) assay, SCC7 cells and CTLs were mixed and CTL-mediated SCC7 cells cytotoxicity was tested. The experiment included four groups: Control group (T lymphocyte + DC), IDO inhibition group (T lymphocyte + DC + IDO inhibitor), Anti-PD-L1 antibody group (T lymphocyte + DC + anti-PD-L1 antibody) and Combination group (T lymphocyte + DC + IDO inhibitor + anti-PD-L1 antibody). The SCC7 tumor-bearing mice treated with IDO inhibitor and the anti-PD-L1 antibody were sacrificed and the tumor inhibition rate and the spleen index were determined. Results: Compared with Control group, exogenous VEGF or SCC7 co-culture inhibited the relative number of DC expressing CD11C, CD80, CD86, CD40 and MHC Ⅱ. The positive DCs were increased in the Anti-VEGF group compared with VEGF or Co-culture group. In VEGF or Co-culture group, the number of T cells stimulated by SCC7-pulsed DCs was decreased compared with Control group. However, the ability of Anti-VEGF group to induce T cell proliferation was significantly increased compared with VEGF or Co-culture group. Significantly increased expression of IDO and PD-L1 were observed in VEGF and Co-culture group. However, this was partially reversed by addition of anti-VEGF antibody into the co-culture system. Compared with Control group, the expressions of CD11C and CD86 in DC in both the IDO inhibition group and Anti-PD-L1 antibody group were increased, and were significantly higher in the Combination group compared with the single drug groups. The similar results were exhibited in MLR and CTL assay. In vivo, the results revealed that the tumors obtained from the mice in three experimental groups were smaller than those in the control group. Furthermore, the tumor volume of the Combination group was the smallest. The spleen index of each group was calculated and the results showed the spleen index of the three experimental groups was significantly higher than that of Control group. Conclusion VEGF in OSCC micro-environment inhibits the maturation and function of DC that are transformed into tolerogenic DC by high expression of IDO and PD-L1.

Objective:To identify the risk factors of postoperative atrial fibrillation (POAF) in critically ill lung surgery patients and establish a nomogram.Methods:213 critically ill lung surgery patients were collected in Beijing Chaoyang Hospital from January 2018 to December 2021. Logistic analysis was used to analyze the risk factors of POAF. A nomogram was developed based on the verified risk factors. Results:The independent risk factors associated with POAF was mitral regurgitation ( OR=4.270, 95% CI: 1.380-13.213, P=0.012), cedilanid ( OR=14.619, 95% CI: 2.913-73.373, P=0.001), catecholamine ( OR=3.244, 95% CI: 1.144-9.203, P=0.027), pericardiotomy( OR=6.079, 95% CI: 1.362-27.128, P=0.009), systematic lymph node dissection( OR=5.460, 95% CI: 1.770-16.846, P=0.003). Nomogram model showed the ROC was 0.801(95% CI: 0.721-0.881, P<0.001). Conclusion:The risk factors of POAF in critically ill lung surgery patients are mitral regurgitation, cedilanid, catecholamine, pericardiotomy and systematic lymph node dissection. The nomogram predicted POAF better than other scoring systems.
