Stroke ranks as the third leading cause of death and the fourth leading cause of disability worldwide. Its high disability rate and prolonged recovery period not only severely impact patients' quality of life but also impose a significant burden on families and society. Primary prevention is the cornerstone of stroke control, as early intervention on risk factors can effectively reduce its incidence. Therefore, the development of predictive models for first-ever stroke risk holds substantial clinical value. In recent years, advancements in big data and artificial intelligence technologies have opened new avenues for stroke risk prediction. This article reviews the current research status of traditional methods and machine learning models in predicting first-ever stroke risk and outlines future development trends from three perspectives: First, emphasis should be placed on technological innovation by incorporating advanced algorithms such as deep learning and large models to further enhance the accuracy of predictive models. Second, there is a need to diversify data types and optimize model architectures to construct more comprehensive and precise predictive models. Lastly, particular attention should be given to the clinical validation of models in real-world settings. This not only enhances the robustness and generalizability of the models but also promotes physicians' understanding of predictive models, which is crucial for their application and dissemination.

OBJECTIVE To compare the efficacy and safety of dupilumab versus thalidomide in the treatment of refractory prurigo nodularis （PN） in adults. METHODS A retrospective analysis was conducted on the clinical data of 123 adult patients with refractory PN admitted to Wuhan First Hospital from May 2021 to June 2024. Among them， 63 patients who received dupilumab comprised the observation group and 60 patients who received thalidomide comprised the control group. Clinical efficacy indicators [Investigator Global Assessment （IGA） score， Pruritus Numerical Rating Scale （P-NRS） score， Patient-Oriented Eczema Measure （POEM） score， and Dermatology Life Quality Index （DLQI） score]， allergic biomarkers [eosinophil （EOS） count in peripheral blood and serum total immunoglobulin E （IgE） level]， psychological scores [Hospital Anxiety and Depression Scale （HADS）] before and after treatment， as well as the occurrence of adverse drug reaction during treatment， were compared between the two groups. RESULTS Before treatment， there were no statistically significant differences between the two groups in above clinical efficacy indicators， allergic biomarkers， or psychological scores （P＞0.05）. At 4， 8， 12 and 16 weeks after treatment， both groups showed significant decreases in IGA score （except for the control group 4 weeks after treatment）， IGA activity score （except for the control group 4 weeks after treatment）， P-NRS score， POEM score， DLQI score （except for the control group 4 weeks after treatment）， serum EOS count， and serum total IgE level compared with baseline （P＜0.05）； at 12 and 16 weeks after treatment， scores on both the HADS-anxiety subscale and HADS-depression subscale were also significantly lower than baseline in both groups （P＜0.05）； the observation group was significantly lower than the control group （P＜0.05）. The overall incidence of adverse events was 12.70% in the observation group， which was significantly lower than 28.33% in the control group （P＜0.05）. CONCLUSIONS Dupilumab treatment in adults with refractory PN demonstrates superior efficacy compared with thalidomide in improving skin lesions， relieving pruritus， reducing peripheral EOS counts and serum total IgE， and improving quality of life and psychological status， while showing a more favorable safety profile.

Objective To investigate the levels of gross α and gross β activities in different water types within a 40-kilometer radius around the Zhangzhou Nuclear Power Plant prior to its operation. Methods In 2018, drinking water samples were collected from the area surrounding the nuclear power plant during both the wet and dry seasons, including source water, treated water, tap water, and well water. The gross α and gross β activity concentrations were measured using a low-background α/β counter, followed by statistical analysis. Results A total of 80 water samples from different sources around the Zhangzhou Nuclear Power Plant were collected. The average gross α and gross β activity concentrations during the wet season were (0.110 ± 0.036) Bq/L and (0.643 ± 0.028) Bq/L, respectively, while those during the dry season were (0.124 ± 0.032) Bq/L and (0.624 ± 0.026) Bq/L, respectively. There were no significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for the overall sample set (P > 0.05). However, there were statistically significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for source water and well water (Z_wet = −2.005, −2.123; Z_dry = −1.943, −3.090; P < 0.05). Conclusion The radioactivity levels in different water types within various ranges around the Zhangzhou Nuclear Power Plant before its operation were determined. The measured activity concentrations were at the same level as those from previous investigations in other regions of Fujian Province.

A 1-year and 9-month-old male proband presented with clustered rice grain-sized flat smooth red papules on the face, trunk and limbs for 1.5 years, without fever, joint swelling, or pain. The proband′s sister aged 7 years ever experienced swelling and pain in the finger joints of both hands at the age of 2 years, and had intermittent fever and papules all over the body at the same time, and the papules gradually regressed with the subsidence of fever. The proband′s mother aged 27 years suffered from swelling and pain in the finger joints of both hands when she was young, gradually leading to finger deformities, and experienced intermittent knee swelling and pain at the age of 12 years without obvious skin lesions on the body. No abnormality was found in ophthalmological and systemic physical examinations of the 3 patients. Whole-exome sequencing showed that the proband, his sister and mother all had a heterozygous missense mutation c.1001G>A (p.R334Q) in exon 4 of the NOD2 gene. A diagnosis of Blau syndrome was made. The proband was treated with topical moisturizing cream all over the body; during the 52-week follow-up, no joint swelling and pain or eye symptoms were found in the proband, while erythema and depressed scars were observed on the face, trunk and limbs. The proband′s sister and mother were treated with subcutaneous injections of adalimumab at initial doses of 40 mg and 80 mg respectively, followed 1 week later by injections at 20 mg and 40 mg respectively, and then treated with injections at 20 mg and 40 mg respectively every 2 weeks; after 12-week treatment, the joint swelling and pain were markedly relieved in the proband′s sister and mother, and most skin lesions subsided in the proband′s sister; at week 52 during the follow-up, there was no joint swelling, pain or skin lesions in the proband′s sister, and there was no swelling or pain in the knee joints of the proband′s mother, while no improvement was observed in her finger deformities. During the treatment, no eye symptoms or adverse reactions were observed neither in the proband′s sister nor in his mother.

Objective:To investigate changes in disease status and their influencing factors in patients with moderate to severe plaque psoriasis treated with biologics during the coronavirus disease 2019 (COVID-19) pandemic.Methods:Through printed or electronic questionnaires during February 10 th - 20 th, 2023, data were collected from patients with moderate to severe plaque psoriasis treated with biologics in Henan Provincial People′s Hospital from June 2019 to January 2023, and changes in the disease condition during the COVID-19 pandemic were investigated. The t test or chi-square test was used for comparisons between groups, univariate analysis and multivariate logistic regression analysis were conducted to investigate the factors contributing to the exacerbation of psoriasis, and stratified analysis was employed to evaluate the disease progression among the patients receiving different biologic therapies following treatment delays. Results:A total of 177 patients with moderate to severe plaque psoriasis were collected, including 115 males and 62 females; they were aged 6 - 83 (38.69 ± 14.18) years, with disease duration of 1 - 50 (13.48 ± 9.70) years. Among the patients, 74 (41.81%) experienced psoriasis exacerbation, 154 (87.01%) developed COVID-19, and 90 (50.85%) experienced delays in psoriasis treatment due to the pandemic. The results of univariate analysis indicated significant associations of psoriasis exacerbation with treatment delays, irregular treatment before the pandemic, and incomplete clearance of skin lesions ( P < 0.001 or 0.05), while no correlations were observed between psoriasis exacerbation and COVID-19 or gender (both P > 0.05). Multivariate logistic regression analysis demonstrated that psoriasis exacerbation was associated with treatment delays due to COVID-19 ( OR = 3.34, 95% CI: 1.35 - 8.22, P = 0.009) and incomplete clearance of skin lesions ( OR = 3.10, 95% CI: 1.28 - 7.50, P = 0.012), but not associated with irregular treatment before the pandemic ( P = 0.130). Among the patients treated with adalimumab, secukinumab, ustekinumab, and ixekizumab, those experiencing treatment delays exhibited higher rates of psoriasis exacerbation than those without treatment delays (all P < 0.05) . Conclusion:Patients with moderate to severe plaque psoriasis undergoing biologic therapy are prone to disease exacerbation when treatment is delayed due to COVID-19, especially those with incomplete lesion clearance.

Objective:To observe the change of retinal artery angle in eyes with idiopathic epiretinal membrane (ERM) and to analyze the relationship between retinal artery angle, ERM classification based on optical coherence tomography (OCT), and visual acuity.Methods:A retrospective cross-sectional clinical study. A total of 187 eyes in 187 patients diagnosed with monocular idiopathic ERM (IERM group) in Department of Ophthalmology of Zhejiang Provincial People's Hospital and the Affiliated Eye Hospital of Wenzhou Medical University at Hangzhou from November 2018 to January 2023 were included in the study. The contralateral healthy eyes were included as the control group. All patients underwent best corrected visual acuity (BCVA), fundus photography, spectral-domain OCT, OCT angiography (OCTA) and axial length (AL) measurement. BCVA examination was performed using the standard logarithmic visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. The foveal avascular zone (FAZ) area was measured by OCTA. The central macular thickness (CMT) was measured by spectral domain OCTaccording to the grading criteria of ectopic inner foveal layer (EIFL) was divided into stages 1 to 4 with 42, 45, 62, and 38 eyes, and the IERM group was subdivided into stage 1, stage 2, stage 3, and stage 4 groups accordingly. Image J was used to measure the retinal artery angle and the 1/2 retinal artery angle on fundus images. Multiple linear regression analysis was used to analyze the correlation between BCVA and artery angle, 1/2 artery Angle, CMT, FAZ area and AL.Results:Compared with the control group, eyes in IERM group had worse BCVA ( t=9.727), thicker CMT ( t=12.452), smaller FAZ area ( t=-14.329), smaller artery angle ( t=-9.165) and smaller 1/2 artery angle ( t=-9.549). The differences were statistically significant ( P<0.001). With the increase of IERM stage, the artery angle and 1/2 artery angle decreased significantly ( F=21.763, 12.515; P<0.001). There was no significant difference in artery angle and 1/2 artery angle between stage 1 group and stage 2 group, and 1/2 arterial angle between stage 2 group and stage 3 group ( P>0.05). There were significant differences in artery angle and 1/2 artery angle between the other groups ( P<0.05). There were significant differences in CMT and logMAR BCVA among different classification subgroups in IERM groups ( P<0.05). There was no significant difference in FAZ area between grade 3 group and grade 4 group ( P>0.05). There were significant differences in FAZ area between the other groups ( P<0.05). Correlation analysis showed that decreased artery angle ( P=0.013) and increased CMT ( P<0.001) were associated with decreased BCVA. Conclusions:Compared with healthy eyes, the artery angle decreases significantly with the increase of ERM stage. Decreased retinal artery angle is associated with decreased visual acuity in IERM eyes.

Diabetic macular edema (DME) is the main cause of vision loss in diabetic patients, its pathogenesis is complicated, and the clinical treatment is not good. DME is extremely harmful to vision. With the deepening of relevant studies, its related pathological mechanism has become more and more clear, and the treatment methods have also changed accordingly. In recent years, the rapid development of intracocular fluid cytokine detection technology has provided a more reasonable explanation of the mechanism of DME and made the choice of treatment more reasonable. However, the acquisition of intraocular fluid is an invasive operation with a certain risk of infection. If the level of relevant cytokines in intraocular fluid can be linked with the relevant imaging indicators, it will provide a better choice for the treatment and prognosis monitoring of DME and reduce the risk of invasive operation, and further clinical studies are needed to explore its correlation in the future.
