AIM:To investigate the value of optical coherence tomography angiography(OCTA)indicators in the diagnosis of diabetic retinopathy(DR), and to provide patients with diabetic nephropathy(DN)with more sensitive OCTA screening indicators to detect concurrent DR at an early stage.METHODS: A total of 200 patients who treated in the ophthalmology department of the Seventh Affiliated Hospital, Sun Yat-sen University from 2022 to 2023 were included, including 95 first-diagnosed DR patients and 105 patients without DR, and all patients underwent OCTA examination and a collection of demographics and renal function parameters. After a quality check, automated measurements of the foveal avascular zone area, vessel density(VD), and perfusion density(PD)of both 3 mm×3 mm and 6 mm×6 mm windows were obtained.RESULTS: Using random forest and multivariate Logistic regression methods, we developed a diagnostic model for DR based on 12 variables(age, FBG, SBP, DBP, HbA1c, ALT, ALP, urea/Scr, DM duration, HUA, DN, and CMT). Adding specific OCTA parameters enhanced the efficacy of the existing diagnostic model for DR(outer vessel density in 6 mm×6 mm window, AUC=0.837 vs 0.819, P=0.03). In the study of DN patients, the parameters in the 6 mm×6 mm window improved the diagnostic efficacy of DR(inner VD; outer VD; full VD; outer PD; full PD).CONCLUSION:The outer VD in the 6 mm×6 mm window can enhance the efficacy of the traditional DR diagnostic model. Meanwhile, compared with the 3 mm×3 mm window, the microvascular parameters in the 6 mm× 6 mm window focusing on DN patients can be more sensitive to diagnosing the occurrence of DR.

Background Hypertension is one of the chronic diseases with the highest prevalence in China, and a history of hypertension may potentially exacerbate hearing loss. Investigating the association between long-term blood pressure trends and hearing thresholds could contribute to hearing protection efforts for occupationally noise-exposed populations. Objective By investigating hearing thresholds and blood pressure levels among occupationally noise-exposed workers in an urban rail transit enterprise, and conducting a comprehensive analysis of the association between long-term blood pressure changes and hearing thresholds, to provide data references for health management strategies targeting occupationally noise-exposed workers. Methods Workers exposed to occupational noise at a rail transit enterprise were enrolled as study subjects and underwent pure-tone audiometry. Group-based trajectory modeling was employed to identify blood pressure trajectories. Categorical data were compared using chi-square tests, while normally distributed continuous variables were analyzed via t-tests and analysis of variance (ANOVA). Generalized linear mixed models (GLMMs) were subsequently applied toexamine associations between these trajectory groups and high-frequency hearing thresholds. Results Among 2 002 occupationally noise-exposed workers, the median (P25, P75) age was 32 (28, 35) years, with a median (P25, P75) working tenure of 7 (3, 10) years. In 2019, the positive hypertension rate was 9.04%, with a mean systolic blood pressure (SBP) of (122.97±11.60) mmHg and a mean diastolic blood pressure (DBP) of (76.37±9.02) mmHg. The hearing loss prevalence was 10.1%, showing bilateral high-frequency average hearing thresholds of (17.18±8.71) dB and speech-frequency average thresholds of (13.79±3.46) dB. Three distinct trajectory groups were identified for both SBP and DBP. Compared with other trajectory groups, the high-stable DBP group exhibited significantly higher hearing loss prevalence (χ2=6.34, P=0.042) and elevated high-frequency hearing thresholds (all Ps<0.05). Specifically, within the 30-39 age subgroup, the moderate-stable DBP group demonstrated 1.96 dB lower high-frequency thresholds than the high-stable group [β(95%CI): −1.96 (−3.61, −0.32), P=0.020]. Conclusion Among occupationally noise-exposed workers in a municipal rail transit enterprise, DBP trajectories demonstrated a positive association with high-frequency hearing thresholds. Notably, in young and middle-aged occupationally noise-exposed populations, DBP may exert a more critical influence than SBP on the progression of hearing loss.

AIM: To review and summarize the current research and achievements in the field of diabetic cataract, with the aim of better identifying research hotspots and trends in this area.METHODS: Based on the relevant literature retrieved from the China National Knowledge Infrastructure, Web of Science databases, and Pubmed, a bibliometric analysis of the diabetic cataract was conducted by means of Microsoft Office Excel 2017 and CiteSpace 6.3R2. Research hotspots were subsequently synthesized after visualizations of author/country collaborations, co-citation networks of highly cited literature, keyword clustering, and emergence.RESULTS: A total of 815 Chinese and 572 English publications were finally included. Overall, this field had maintained substantial scholarly attention globally, though publications had progressively decreased since 2018. While inter-institutional collaboration in this area remained limited, a multinational collaborative network had emerged with the People's Republic of China, the United States of America, the United Kingdom, and the Kingdom of Spain as central hubs. Core research priorities in diabetic cataract consistently encompassed surgical and pharmacological interventions, pathogenesis, associated ocular/systemic complications; while international and domestic research contents aligned fundamentally in these domains, but the domestic research was unique in nursing interventions and herbal medicine-based interventions. Recent analytical trends revealed that Chinese investigations prioritized the pathogenic mechanisms of diabetic cataract, whereas international efforts concentrated on clinical therapeutics.CONCLUSION: This bibliometric analysis of diabetic cataract research literature(2000-2024)synthesizes the current advancements, research priorities, and scholarly contributions in the field, and intuitively demonstrates significant academic merit and clinical relevance, which can provide evidence-based guidance for the future research trajectories.

OBJECTIVES:
To investigate the relationship between the polygenic risks for various psychiatric disorders and clinical and neuropsychological characteristics in children with attention-deficit/hyperactivity disorder (ADHD).
METHODS:
Using a cross-sectional design, 285 children with ADHD and 107 healthy controls were assessed using the Child Behavior Checklist, the Behavior Rating Inventory of Executive Function for parents, the Wechsler Intelligence Scale for Children, Fourth Edition, and the Cambridge Neuropsychological Test Automated Battery. Blood samples were collected for genetic data. Polygenic risk scores (PRSs) for various psychiatric disorders were calculated using the PRSice-2 software.
RESULTS:
Compared with the healthy controls, the children with ADHD displayed significantly higher PRSs for ADHD, major depressive disorder, anxiety disorder, and obsessive-compulsive disorder (P<0.05). In terms of daily-life executive function, ADHD-related PRS was significantly correlated with the working memory factor; panic disorder-related PRS was significantly correlated with the initiation factor; bipolar disorder-related PRS was significantly correlated with the shift factor; schizophrenia-related PRS was significantly correlated with the inhibition, emotional control, initiation, working memory, planning, organization, and monitoring factors (P<0.05). The PRS related to anxiety disorders was negatively correlated with total IQ and processing speed index (P<0.05). The PRS related to obsessive-compulsive disorder was negatively correlated with the processing speed index and positively correlated with the stop-signal reaction time index of the stop-signal task (P<0.05).
CONCLUSIONS
PRSs for various psychiatric disorders are closely correlated with the behavioral and cognitive characteristics in children with ADHD, which provides more insights into the heterogeneity of ADHD.

BACKGROUND:
Both medication and non-medication therapies are effective approaches to control blood pressure (BP) in hypertension patients. However, the association of joint changes in antihypertensive medication use and healthy lifestyle index (HLI) with BP control among hypertension patients is seldom reported, which needs to provide more evidence by prospective intervention studies. We examined the association of antihypertensive medication use and HLI with BP control among employees with hypertension in China based on a workplace-based multicomponent intervention program.
METHODS:
Between January 2013 and December 2014, a cluster randomized clinical trial of a workplace-based multicomponent intervention program was conducted in 60 workplaces across 20 urban areas in China. Workplaces were randomly divided into intervention (n = 40) and control (n = 20) groups. Basic information on employees at each workplace was collected by trained professionals, including sociodemographic characteristics, medical history, family history, lifestyle behaviors, medication status and physical measurements. After baseline, the intervention group received a 2-year intervention to achieve BP control, which included: (1) a workplace wellness program for all employees; (2) a guidelines-oriented hypertension management protocol. HLI including nonsmoking, nondrinking, adequate physical activity, weight within reference range and balanced diet, were coded on a 5-point scale (range: 0-5, with higher score indicating a healthier lifestyle). Antihypertensive medication use was defined as taking drug within the last 2 weeks. Changes in HLI, antihypertensive medication use and BP control from baseline to 24 months were measured after the intervention.
RESULTS:
Overall, 4655 employees were included (age: 46.3 ± 7.6 years, men: 3547 (82.3%)). After 24 months of the intervention, there was a significant improvement in lifestyle [smoking (OR = 0.65, 95% CI: 0.43-0.99; P = 0.045), drinking (OR = 0.52, 95% CI: 0.40-0.68; P < 0.001), regular exercise (OR = 3.10, 95% CI: 2.53-3.78; P < 0.001), excessive intake of fatty food (OR = 0.17, 95% CI: 0.06-0.52; P = 0.002), restrictive use of salt (OR = 0.26, 95% CI: 0.12-0.56; P = 0.001)]. Compare to employees with a deteriorating lifestyle after the intervention, those with an improved lifestyle had a higher BP control. In the intervention group, compared with employees not using antihypertensive medication, those who consistent used (OR = 2.34; 95% CI: 1.16-4.72; P = 0.017) or changed from not using to using antihypertensive medication (OR = 2.24; 95% CI: 1.08-4.62; P = 0.030) had higher BP control. Compared with those having lower HLI, participants with a same (OR = 1.38; 95% CI: 0.99-1.93; P = 0.056) or high (OR = 1.79; 95% CI: 1.27~2.53; P < 0.001) HLI had higher BP control. Those who used antihypertensive medication and had a high HLI had the highest BP control (OR = 1.88; 95% CI: 1.32-2.67, P < 0.001). Subgroup analysis also showed the consistent effect as the above.
CONCLUSION
These findings suggest that adherence to antihypertensive medication treatment and healthy lifestyle were associated with a significant improvement in BP control among employees with hypertension.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.

Objective:Chronic urticaria presents a chronic process of recurrent attacks,and its first-line treatment is second-generation antihistamine with limited treatment options.The efficacy of antihistamine varies among individuals and cannot meet the needs of all patients.This study aims to explore the clinical efficacy and safety of Zhiyang Xiaozhen granules combined with antihistamine in the treatment of chronic urticaria patients. Methods:We retrospectively analyzed the clinical data of patients with chronic urticaria who visited the Xiangya Hospital of Central South University from April 2020 to March 2021.The patients who received conventional second-generation antihistamine treatment were selected as a control group,while the patients who received combined treatment with Zhiyang Xiaozhen granules on the basis of conventional second-generation antihistamine treatment were selected as an observation group.The differences in the Weekly Urticaria Activity Score(UAS7)and Dermatology Life Quality Index(DLQI)between the 2 groups before and 4 weeks after treatment were compared.The Symptom Score Reduce Index(SSRI)was used to evaluate and compare the efficacy of the 2 treatment regimens. Results:After 4 weeks of treatment,the UAS7 levels in both groups were significantly reduced(P=0.001 and P<0.001,respectively).The effective rates of the control group and the observation group were 61.11%and 59.38%,respectively when converting UAS7 to SSRI for efficacy evaluation,and there was no statistically significant difference in efficacy between the 2 groups(P>0.05);however,when converting DLQI to SSRI for efficacy evaluation,the effective rates of the control group and the observation group were 33.33%and 46.88%,respectively,and the difference in efficacy between the 2 groups was statistically significant(P<0.001).There were 3 patients with adverse drug reactions related to drowsiness in both groups. Conclusion:The combination of Zhiyang Xiaozhen granules and second-generation antihistamine can effectively improve disease activity in patients with chronic urticaria,and the improvement in quality of life is better than that with the second-generation antihistamine alone.

Objective:To explore whether Ph+acute lymphoblastic leukemia (ALL)cell line SUP-B15 treated with imatinib occurs a tolerant status charactered by cell proliferation suppression but apoptotic resistance,then evaluate whether IGF1-R inhibitor AEW541 can break this tolerance,and further explain its mechanisms.Methods:SUP-B15 cells were treated with different concentrations of imatinib or AEW541.Cell proliferation was assayed by Deep Blue,and apoptotic cells were determined by Annexin V/7-AAD staining.Apoptotic rate was measured by flow cytometry after co-treatment of imatinib and AEW541.Western blot was used to evaluate ABL downstream signals,including the phosphorylation of STAT5,ERK1/2,and AKT,as well as to detect cleaved caspase-3 and PARP1,the molecular signatures of apoptosis.Furthermore,an inhibitor of STAT5 or MEK-ERK1/2 was used to confirm the key mechanism of the combination of imatinib and AEW541 induced SUP-B15 cell apoptosis.Results:Imatinib monotherapy effectively suppressed the proliferation of SUP-B15 cells,but did not induce significant increase of apoptotic rate,leading to occurrence of tolerant status.AEW541 monotherapy did not dramatically affect the proliferation and apoptosis of SUP-B15 cells,but significantly increased apoptotic rate of SUP-B15 cells and cleavage of caspase-3 and PARP1 when combined with imatinib simultaneously. A combination of imatinib and AEW541 reduced STAT5 and ERK1/2 phosphorylation as compared with imatinib monotherapy in SUP-B15 cells,but had no impact on AKT phosphorylation.Apoptosis could be induced by STAT5 inhibitor AC-4-130,but not by MEK-ERK1/2 inhibitor trametinib in SUP-B15 cells.Conclusion:SUP-B15 cells treated with imatinib can establish drug tolerance.IGF1-R inhibitor AEW541 can further reduce STAT5 activation,thereby boosting the effect of apoptotic induction of imatinib on SUP-B15 cells.This research may provide a new idear to overcome imatinib tolerance.

Breast cancer has been the second most common solid tumor that metastasizes to the central nervous system after lung cancer.Triple-negative breast cancer(TNBC)has an earlier occurrence and high incidence of brain metastasis with its associated poor prognosis and limited treatment options due to the presence of the blood-brain barrier and lack of targeted drugs.Local treatment,including surgery and radiation therapy,are still the main therapy for brain metastasis.Surgical resection can not only relieve neurologic impairment of brain metastasis patients,but also can clarify the pathological type.Moreover,surgical resection combined with radiotherapy can improve the prognosis of brain metastasis patients compared to surgery or radiotherapy alone.By now,whole-brain radiation therapy(WBRT)is still considered the gold standard for multiple brain metastases,and meningeal metastases,but it will lead to neurocognitive decline,so hippocampal avoidance is essential.For selected patients with oligometastases,stereotactic radiotherapy has replaced WBRT to reduce cognitive toxicity.However,local treatment of TNBC brain metastasis cannot control the progress of brain metastasis and has significant side effects,so systemic therapy is needed.Chemotherapy drugs such as capecitabine and cisplatin can penetrate the blood-brain barrier,but their efficacy is limited.Therefore,the research and development of new targeted drugs and the exploration of new targets are necessary for TNBC brain metastasis.Research has found that patients carrying germline BRCA1/2 mutations have a higher risk of brain metastasis.Currently,the poly adenosine diphosphate ribose polymerase(PARP)inhibitor demonstrated antitumor activity in patients with advanced breast cancer and a germline BRCA1/2 mutation,and it can penetrate the blood-brain barrier.The phase Ⅲ trial EMBRACA reported that the PARP inhibitor talazoparib can prolong the progression-free survival of TNBC patients with brain metastasis.In addition,antibody drug conjugates(ADCs)trastuzumab deruxtecan(T-DXd)can also penetrate the blood-brain barrier.Studies such as DEBBRAH have shown that T-DXd has significant therapeutic effects in HER2 positive brain metastasis patients,while research on HER2 low expression patients has not yet reached the endpoint,and its role in TNBC brain metastasis is worth looking forward to.Sacituzumab govitecan(SG)is also an ADC composed of an antibody targeting the human trophoblast cell-surface antigen 2.The phase Ⅲ ASCENT study showed that in the full population(including 61 patients with brain metastasis),SG could significantly prolong the progression-free survival of advanced TNBC patients compared to the patients who received chemotherapy.ANG1005,a novel taxane derivative,can cross the blood-brain barrier as well.A multicenter,open-label phase Ⅱ study revealed that ANG1005 could prolong overall survival of patients with brain metastasis.In addition,phosphoinositide3-kinase,(PI3K)/protein kinase(AKT)/mammalian target of rapamycin(mTOR)pathway inhibitors,fatty acid synthase inhibitors,and the drugs with new delivery systems have become potential treatment options for TNBC brain metastasis patients.Although the Impassion 130 reported that no benefit trend for immunotherapy in TNBC brain metastasis,basic research has shown that radiotherapy combined with immunotherapy has a synergistic effect.Currently,multiple clinical trials(NCT03483012,NCT03449238,etc.)are exploring the efficacy of radiotherapy combined with immunotherapy in brain metastasis,and the results are promising.This article reviewed the research progress of TNBC brain metastasis treatment.
