Myopia has become a growing public health issue globally, characterized by an earlier age of onset and a rising annual incidence rate, particularly among adolescents. Repeated low-intensity red light therapy(RLRL)has gained widespread attention in recent years as an emerging non-invasive intervention, showing promise for controlling myopia. This article examines the role of the PI3K/AKT signaling pathway in RLRL,specifically advances in promoting choroidal thickening via the phosphorylation mechanism of endothelial nitric oxide synthase(eNOS). Choroidal thickening is recognized as a critical part of myopia control. Activation of the PI3K/AKT/eNOS-NO signaling pathway may attenuate axial elongation by enhancing choroidal blood flow and nutrient supply. Although certain basic and clinical studies have supported this mechanism, many unresolved issues still remain, such as the specific mechanisms of RLRL action, its safety, and its applicability in different populations. This article systematically reviews the relevant research progress, aiming to provide a valuable reference for future studies and explore the application prospects of RLRL in myopia prevention and control.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

OBJECTIVE: To investigate the association between ABO blood types and gestational diabetes mellitus (GDM) risk. METHODS: A prospective birth cohort study was conducted. ABO blood types were determined using the slide method. GDM diagnosis was based on a 75-g, 2-h oral glucose tolerance test (OGTT) according to the criteria of the International Association of Diabetes and Pregnancy Study Groups. Logistic regression was applied to calculate the odds ratios ( ORs) and 95% confidence intervals ( CIs) between ABO blood types and GDM risk. RESULTS: A total of 30,740 pregnant women with a mean age of 31.81 years were enrolled in this study. The ABO blood types distribution was: type O (30.99%), type A (26.58%), type B (32.20%), and type AB (10.23%). GDM was identified in 14.44% of participants. Using blood type O as a reference, GDM risk was not significantly higher for types A ( OR = 1.05) or B ( OR = 1.04). However, women with type AB had a 19% increased risk of GDM ( OR = 1.19, 95% CI = 1.05-1.34; P < 0.05), even after adjusting for various factors. This increased risk for type AB was consistent across subgroup and sensitivity analyses. CONCLUSION The ABO blood types may influence GDM risk, with type AB associated with a higher risk. Incorporating it-either as a single risk factor or in combination with other known factors-could help identify individuals at risk for GDM before or during early pregnancy.

As a serine protease,thrombin can convert soluble fibrinogen into insoluble fibrin and plays a pivotal role in the coagulation cascade.Therefore,the accurate quantitative assay of thrombin levels is of great value in the evaluation of coagulation function,clinical screening and prognostic monitoring of coagulation-related diseases,and screening of drugs for targeted therapy.Existing methods for thrombin detection can be divided into two categories,e.g.,the assay of concentration levels using nucleic acid aptamers as the affinity elements and the assay of activity levels based on the hydrolytic cleavage of substrate peptides.In recent years,electrochemical biosensors have attracted much attention in thrombin detection due to high sensitivity,high selectivity,simple instrument,fast response,and good portability.In this review,the latest research progress in methods for electrochemical detection of thrombin was summarized,focusing on the detection principles and the applied signal amplification strategies of related electrochemical biosensors.In addition,the challenges with respect to the practical use of electrochemical thrombin biosensors and the prospects were discussed.

Objective To investigate the relationship between serum programmed cell death 4(PDCD4),platelet-derived growth factor-BB(PDGF-BB)levels and atherosclerotic cardiovascular disease(ASCVD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 238 T2DM patients admitted to 3201 Hospital from January 2022 to August 2024 were selected as the T2DM group,and 120 healthy volunteers who visited the hospital for physical examination during the same period were selected as the control group.T2DM patients were divided into ASCVD group(82 cases)and non-ASCVD group(156 cases)according to the presence or absence of ASCVD.The serum levels of PDCD4 and PDGF-BB were detected by enzyme-linked immunosorbent assay.Multivariate unconditional Logistic regression was used to analyze the relationship be-tween serum PDCD4 and PDGF-BB levels and ASCVD in T2DM patients.Receiver operating characteristic curve was used to analyze the predictive efficiency of serum PDCD4 and PDGF-BB levels for ASCVD in T2DM patients.Results Compared with the control group,the serum levels of PDCD4 and PDGF-BB were signifi-cantly increased in the T2DM group(P<0.05).The incidence of ASCVD in the 238 patients with T2DM was 34.45%(82/238).Compared with the non-ASCVD group,the ASCVD group had significantly higher serum levels of PDCD4 and PDGF-BB(P<0.05).Hypertension,hyperlipidemia,high glycosylated hemoglobin,high PDCD4 and high PDGF-BB were independent risk factors for ASCVD in T2DM patients(P<0.05).The area under the curve of serum PDCD4 and PDGF-BB levels combined to predict ASCVD in T2DM patients was 0.873,which was larger than 0.790 and 0.780 predicted by serum PDCD4 and PDGF-BB levels alone(P<0.05).Conclusion The serum levels of PDCD4 and PDGF-BB are increased in patients with T2DM,which are independent risk factors for ASCVD.The combination of PDCD4 and PDGF-BB has a high predictive efficiency for ASCVD in patients with T2DM.

Aim To investigate the effect of circRNF13 on oxaliplatin resistance in colorectal cancer cells and its related mechanism.Methods Cell transfection was used to overexpress circRNF13 in oxaliplatin-sensi-tive colorectal cancer cells SW620 or to inhibit cir-cRNF13 expression in oxaliplatin-resistant colorectal cancer cells SW620/OXA.Real-time quantitative fluo-rescent PCR(qRT-PCR)was used to detect the ex-pression levels of circRNF13,miR-16-5p,and mir-324-5p.Cell Count Kit 8(CCK-8)was used to meas-ure cell viability.Clonal formation experiments were used to measure clonal formation number.Western blot was used to detect CyclinD1,PCNA,Bax,Bcl-2 and cleaved caspase-3 protein expression level.Flow cy-tometry and in situ end labeling(TUNEL)were used to detect apoptosis.Dual luciferase assay was used to verify the targeting relationship between circRNF13 and miR-16-5p and mir-324-5p.Results The expression level of circRNF13 in SW620/OXA cells was signifi-cantly higher than that in SW620 cells,while the ex-pression levels of miR-16-5p and miR-324-5p were sig-nificantly lower than those in SW620 cells(P＜0.05).Overexpression of circRNF13 significantly in-creased the IC50 of oxaliplatin against SW620 cells,and inhibition of circRNF13 expression significantly decreased the IC50 of oxaliplatin against SW620/OXA cells.Overexpression of circRNF13 significantly in-creased cell viability,clonal formation number,Cy-clinD1,PCNA and Bcl-2 levels of oxaliplatin treated SW620 cells,while significantly decreased apoptosis rate,apoptosis index,Bax and cleaved caspase-3 lev-els(P＜0.05).Inhibition of circRNF13 expression significantly decreased the cell viability,clonal forma-tion number,CyclinD1,PCNA and Bcl-2 levels of ox-aliplatin treated SW620/OXA cells,while significantly increased the apoptosis rate,apoptosis index,Bax and cleaved caspase-3 levels(P＜0.05).circRNF13 tar-geted inhibition of the expression of miR-16-5p and mir-324-5p.Conclusions circRNF13 can increase oxaliplatin resistance in colorectal cancer cells,and the mechanism may be related to the targeted inhibition of circRNF13 on the expression of miR-16-5p,mir-324-5p and other miRNAs.

PURPOSE: To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures. METHODS: A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test. RESULTS: During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (all p > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients. CONCLUSION Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

OBJECTIVE: To investigate the characteristics of central nervous system regulation in patients with refractory overactive bladder (rOAB) using resting-state functional magnetic resonance imaging (rs-fMRI), and to analyze the differences in brain function and connection between the patients and healthy population. METHODS: From May 1 to November 30, 2024, we performed rs-fMRI for 47 rOAB patients and another 47 matched healthy controls, documented relevant clinical data from all the participants and obtained their Overactive Bladder Symptom Scores (OABSS) and Overactive Bladder Questionnaire (OAB-Q) scores. Based on rs-fMRI, we compared the results of Independent Component Analysis (ICA), amplitude of low-frequency fluctuations (ALFF), fractional amplitude of low-frequency fluctuations (fALFF), regional homogeneity (ReHo) and degree centrality (DC) between the rOAB patients and healthy controls. RESULTS: The rOAB patients, in comparison with the healthy controls, showed dramatically higher daytime urination frequency (11.64 ± 3.85) vs (5.76 ± 0.91), nighttime urination frequency (3.72 ± 1.64) vs (0.31 ± 0.47), OABSS (8.22 ± 2.21) vs (0.64±0.78), OAB-Q1 score (20.85 ± 5.28) vs (6.78 ± 1.04), and OAB-Q2 score (45.04 ± 12.11) vs (14.51 ± 1.66) (all P<0.01). No statistically significant differences were observed in the results of ICA and ALFF between the right superior frontal and right middle frontal regions in the rOAB patients (P>0.05), but fALFF, ReHo and DC were significantly decreased in the patients compared with those in the healthy controls (P<0.01). CONCLUSION Compared with healthy population, the functions and connection of the frontal superior right and frontal middle right brain regions in rOAB patients are significantly down-regulated, which may serve as new therapeutic targets.

BACKGROUND: Atrial fibrillation (AF) is a common cardiac arrhythmia in the elderly. This study aimed to evaluate urban-rural disparities in its prevalence and management in elderly Chinese. METHODS: Consecutive participants aged ≥ 65 years attending outpatient clinics were enrolled for AF screening using handheld single-lead electrocardiogram (ECG) from April 2017 to December 2022. Each ECG rhythm strip was reviewed from the research team. AF or uninterpretable single-lead ECGs were referred for 12-lead ECG. Primary study outcome comparison was between rural and urban areas for the prevalence of AF. The Student's t-test was used to compare mean values of clinical characteristics between rural and urban participants, while the Pearson's chi-square test was used to compare between-group proportions. Multivariate stepwise logistic regression analysis was performed to estimate the association between AF and various patient characteristics. RESULTS: The 29,166 study participants included 13,253 men (45.4%) and had a mean age of 72.2 years. The 7073 rural participants differed significantly (P ≤ 0.02) from the 22,093 urban participants in several major characteristics, such as older age, greater body mass index, and so on. The overall prevalence of AF was 4.6% (n = 1347). AF was more prevalent in 7073 rural participants than 22,093 urban participants (5.6% vs. 4.3%, P < 0.01), before and after adjustment for age, body mass index, blood pressure, pulse rate, cigarette smoking, alcohol consumption and prior medical history. Multivariate logistic regression analysis identified overweight/obesity (OR = 1.35, 95% CI: 1.17-1.54) in urban areas and cigarette smoking (OR = 1.62, 95% CI: 1.20-2.17) and alcohol consumption (OR = 1.42, 95% CI: 1.04-1.93) in rural areas as specific risk factors for prevalent AF. In patients with known AF in urban areas (n = 781) and rural areas (n = 338), 60.6% and 45.9%, respectively, received AF treatment (P < 0.01), and only 22.4% and 17.2%, respectively, received anticoagulation therapy (P = 0.05). CONCLUSIONS In China, there are urban-rural disparities in AF in the elderly, with a higher prevalence and worse management in rural areas than urban areas. Our study findings provide insight for health policymakers to consider urban-rural disparity in the prevention and treatment of AF.
