Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Guided by the theory of turbid pathogen disturbing clarity， this paper holds that the pathogenesis of otolith disorders involves the failure of clear yang to ascend and the internal generation of phlegm-turbidity as the initiating factors. The clinical manifestations are characterized by the intermingling of phlegm and fluid， as well as the disturbance between turbid and clear substances， while the root lies in spleen-kidney deficiency and depletion of primordial qi. Treatment strategies are formulated according to the different stages of the disease： in the acute phase， therapy focuses on warming and resolving phlegm-fluid retention， using a modified combination of Linggui Zhugan Decoction （苓桂术甘汤） and Zexie Decoction （泽泻汤）； in the residual phase， the approach shifts to tonifying qi and uplifting clear yang， with a modified combination of Shengxian Decoction （升陷汤） and Shengmai Power （生脉散）； in the consolidation phase， therapy aims to tonify the kidney and replenish essence， employing a modified version of Qiju Dihuang Pill （杞菊地黄丸）.

Objective To study the protective effect of polydatin on lipopolysaccharide-induced injury of human umbilical vein vascular endothelial cells(HUVECs)through the protein Janus kinase 2(JAK2)/signal transducers and activators of transcription 3(STAT3)signaling pathway.Methods HUVECs were cultured in vitro,and 500 ng/ml LPS induced their injury and set as a model group;based on the model group,endothelial cells were inter-vened with different concentrations(10,20,and 40 μmol/L)of polydatin for 24 h,and set as polydatin low concentration group,polydatin medium concentration group,and polydatin high concentration group,respectively;a control group was set as another group.CCK-8,monocyte-endothelial cell adhesion,scratch and Transwell assays were used to detect cell viability,adhesion,migration and invasive ability;ELISA was used to detect interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)levels in the cell supernatant;Western blot was used to detect the expression of proteins related to the JAK2/STAT3 signaling pathway levels of JAK2/STAT3 signaling pathway relat-ed proteins.Results Compared with the control group,the model group showed decreased cell survival(P＜0.01),increased cell adhesion,migration and invasion(P＜0.001,P＜0.05,P＜0.01),increased levels of IL-6 and TNF-α in the cell supernatant(P＜0.001),and increased levels of phosphorylation of JAK2 and STAT3 pro-teins in the cells(P＜0.05).Compared with the model group,LPS damage to cells was attenuated after polydatin intervention,cell survival was increased in polydatin low-,medium-and high-concentration groups(P＜0.05),cell adhesion,migration,and invasion decreased(P＜0.05,P＜0.05,P＜0.001),IL-6 and TNF-α levels in cell supernatants decreased(P＜0.05),and the levels of cellular JAK2 and STAT3 protein phosphorylation lev-els decreased(P＜0.05).Conclusion Polydatin seems to reduce the inflammatory injury of human umbilical vein endothelial cells induced by LPS,reducing the secretion of inflammatory factors,and inhibiting the ability of cell ad-hesion,migration and invasion,which may be related to the down-regulation of JAK2/STAT3 signal pathway by polydatin.

Objective:To investigate the clinical manifestations of acquired immunodeficiency syndrome(AIDS) patients with initial-stage cytomegalovirus (CMV) retinitis (CMVR).Methods:Retrospective case series study. From July 2017 to November 2019, 21 patients with 22 eyes of AIDS combined with CMVR in the initial stage of AIDS and CMVR diagnosed in the eye examination in the study. Among them, there were 19 males with 19 eyes and 2 females with 3 eyes; the average age was 34.3±9.6 years. The average CD4 + T lymphocyte count of patients was 26.1±23.2/μl. Routine fundus screening revealed 17 cases, and the contralateral eye disease was found in 4 cases. There were 13 cases of CMVR in both eyes (61.9%, 13/21). Among them, both eyes were in the initial stage of CMVR, and the contralateral eyes were in the early stage of CMVR in 12 cases. The contralateral eye included 2 cases of human immunodeficiency virus-related retinal microangiopathy, 1 case of optic disc edema, and 5 cases of no obvious abnormality on fundus examination. All patients underwent slit lamp microscopy and ultra-wide-angle fundus photography examination. At the same time, 18 eyes underwent optical coherence tomography (OCT). Blood CMV-DNA detection was performed in 17 cases within 1 week before the first diagnosis; aqueous CMV-DNA detection was performed in 7 eyes within 1 week after the first diagnosis. Within 1 week after the fundus examination, 8 eyes of 8 cases and 8 eyes of 7 cases were received and not received systemic anti-CMV treatment; the treatment status was unknown in 6 cases and 6 eyes. After treatment, 18 eyes of 17 cases were followed up. The follow-up time was 0.5-28 months. Results:There were no obvious abnormalities in the anterior segment examination of all the affected eyes; the vitreous body was transparent. The fundus lesions were less than 1 optic disc diameter (DD), and they were white granular, clustered, with blurred edges. Among them, there were granular satellite lesions around the lesion in 18 eyes (81.8%, 18/22). The lesions were located in 19 eyes (86.4%, 19/22) in zone 2, 1 eye in zone 1 and 2 (4.5%, 1/22), and 2 eyes in zone 3 (9.1%, 2/22). In 18 eyes that underwent OCT examination, 12 eyes failed to obtain image data because the lesion was not in the conventional scanning range; the other 6 eyes showed the inner or full retina thickened or atrophy depression, structural destruction, accompanied by local vitreous punctate strong reflection. Among the 17 patients who underwent blood CMV-DNA testing, 1 (5.9%, 1/17) and 16 (94.1%, 16/17) cases were CMV-DNA negative and positive, respectively. The 7 eyes that underwent the CMV-DNA test of aqueous humor were all negative. Among the 18 eyes who were followed up, the lesions did not expand, and gradually subsided and absorbed in 4 eyes (22.2%, 4/18); the varying degrees of lesion enlargement in 14 eyes (77.8%, 14/18).Conclusion:The patients with AIDS and CMVR at the initial stage have no obvious ocular symptoms; the fundus shows white granular lesions less than 1 DD with blurred edges.

Objective:To investigate the ocular characteristics and treatment prognosis of ocular immune reconstruction inflammatory syndrome (IRIS) in patients with cytomegalovirus retinitis (CMVR) complicated with acquired immunodeficiency syndrome (AIDS).Methods:A serial case-observational study was conducted.Seventeen eyes from 15 male 21-to 43-year-old AIDS patients combined with CMVR, who were diagnosed with IRIS at Beijing You'an Hospital, Capital Medical University from February 2016 to December 2018 were included.The best corrected visual acuity (BCVA) of patients was recorded, and the intraocular pressure and anterior segment was measured with a non-contact tonometer and a slit-lamp microscope, respectively.The ocular fundus was observed by fundus photography and optical coherence tomography (OCT). Reverse transcription polymerase chain reaction was used to measure the cytomegalovirus deoxyribonucleic acid (CMV-DNA) content in the aqueous humor during the occurrence of IRIS.The flow cytometry was employed to determine the peripheral blood CD4 + T lymphocyte count before highly active antiretroviral therapy (HAART) and during the occurrence of IRIS.All patients were followed for 3 to 25 months, with an average of 15 months.The HAART time of patients was 17 to 104 days, with an average of (66.1±27.4) days.Patients with anterior segment inflammatory reactions were given the anti-inflammatory and mydriatic treatment.Patients with severe vitreous opacity were intravitreally injected with 4 mg of triamcinolone.Patients with macular edema were given 0.5 mg intravitreal injection of conbercept.The study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Beijing You'an Hospital, Capital Medical University (No.[2017]11). Written informed consent was obtained from each patient prior to any examination. Results:Anterior segment inflammation (Tyndall effect, KP, post-iris adhesion) was found in 9 eyes, vitreous opacities to varying degrees in 11 eyes, and macular edema in 2 eyes.The CMV-DNA content was negative (<500 copies/ml) in 15 eyes.The CD4 + T lymphocyte count in peripheral blood during IRIS was 67 (51, 99) cells/μl, which was significantly higher than 17(6, 20) cells/μl before HAART treatment ( Z=-4.48, P<0.01). Two of the 15 AIDS patients had tuberculosis.The BCVA of the patients was improved from 0.30 (0.10, 0.55) before treatment to 0.50 (0.35, 0.60) after treatment, and the difference was statistically significant ( Z=-2.34, P=0.019). Conclusions:The anterior and posterior segment may be involved in IRIS patients with AIDS and CMVR, and the corresponding ocular treatment is effective.

Objective:To establish a disease risk prediction model for the newborn screening system of inherited metabolic diseases by artificial intelligence technology.Methods:This was a retrospectively study. Newborn screening data ( n=5 907 547) from February 2010 to May 2019 from 31 hospitals in China and verified data ( n=3 028) from 34 hospitals of the same period were collected to establish the artificial intelligence model for the prediction of inherited metabolic diseases in neonates. The validity of the artificial intelligence disease risk prediction model was verified by 360 814 newborns ' screening data from January 2018 to September 2018 through a single-blind experiment. The effectiveness of the artificial intelligence disease risk prediction model was verified by comparing the detection rate of clinically confirmed cases, the positive rate of initial screening and the positive predictive value between the clinicians and the artificial intelligence prediction model of inherited metabolic diseases. Results:A total of 3 665 697 newborns ' screening data were collected including 3 019 cases ' positive data to establish the 16 artificial intelligence models for 32 inherited metabolic diseases. The single-blind experiment ( n=360 814) showed that 45 clinically diagnosed infants were detected by both artificial intelligence model and clinicians. A total of 2 684 cases were positive in tandem mass spectrometry screening and 1 694 cases were with high risk in artificial intelligence prediction model of inherited metabolic diseases, with the positive rates of tandem 0.74% (2 684/360 814)and 0.46% (1 694/360 814), respectively. Compared to clinicians, the positive rate of newborns was reduced by 36.89% (990/2 684) after the application of the artificial intelligence model, and the positive predictive values of clinicians and artificial intelligence prediction model of inherited metabolic diseases were 1.68% (45/2 684) and 2.66% (45/1 694) respectively. Conclusion:An accurate, fast, and the lower false positive rate auxiliary diagnosis system for neonatal inherited metabolic diseases by artificial intelligence technology has been established, which may have an important clinical value.

Objective:To observe the ultra-wide-angle fundus imaging characteristics of acquired immunodeficiency syndrome (AIDS) combined with cytomegalovirus retinitis (CMVR).Methods:This study was a retrospective study. From July 2017 to November 2019, 124 eyes of 86 patients diagnosed with AIDS and CMVR at the Department of Ophthalmology, Beijing You'an Hospital, Capital Medical University, were included in the study. Among them, 80 patients were males (93.0%) and 6 patients were females (7.0%) with 17-58 years old. The average age was (36.86±8.82) years old. There were 48 cases (55.8%) in one eye and 38 cases (44.2%) in both eyes. All the affected eyes underwent indirect ophthalmoscope fundus examination and Aalborg ultra-wide-angle fundus photography examination. According to the characteristics of CMVR in ultra-wide-angle fundus images, it can be divided into classic type, granular type, frost-like dendritic vasculitis and optic neuroretinitis. We observed and analyzed the type of fundus of the affected eye. According to the position of the vortex vein in the fundus image and record of the lesion as the posterior pole or peripheral part, the scope of the lesion was divided into ≤1 quadrant, >1 quadrant and ≤2 quadrants (1-2 quadrants), >2 quadrants and ≤3 quadrants (2-3 quadrants), >3 and ≤4 quadrants (3-4 quadrants). The upper and lower vascular arches or disc edges of the macula were used as boundaries to record whether the macular area or optic disc was involved. At the same time, we recorded whether the vitreous body had obvious turbidity. The comparison of CD4 + T lymphocyte count between patients of different types was performed by one-way analysis of variance, and the comparison of the positive rate of blood CMV-DNA was performed by the χ2 test; pairwise comparisons between groups were performed by the least significant difference method. Results:Among the 124 eyes, CMVR was classified into 35 eyes (28.2%) with classic type, 68 eyes with granular type (54.8%), 3 eyes with frost-like dendritic vasculitis (2.4%), and 18 eyes with optic neuroretinitis (14.5%). The lesion involved 83 eyes (66.9%) at both the posterior pole and the periphery, 22 eyes (17.7%) confined to the posterior pole, and 19 eyes (15.3%) confined to the periphery; the extent of the lesion was ≤1 quadrant in 76 eyes (61.3%), 23 eyes (18.5%) in 1-2 quadrants, 7 eyes (5.6%) in 2-3 quadrants, and 18 eyes (14.5%) in 3-4 quadrants. 54 eyes (43.5%) showed lesions involving the macular area; 52 eyes (41.9%) had lesions involving the optic disc; 33 eyes (26.6%) showed obvious vitreous inflammatory opacities. Among 86 patients, the average number of CD4 + T lymphocytes in 82 patients was 1 to 168 cells/μl, with an average of 33.60±40.02 cells/μl; the remaining 4 patients (4.7%) were unknown. There was no statistically significant difference in the positive rate of CD4 + T lymphocyte count and blood CMV-DNA load between patients in different subtypes groups ( F=0.863, 0.926; P=0.462, 0.431). Conclusion:The ultra-wide-angle fundus images of AIDS combined with CMVR have certain characteristics, which can manifest as classic, granular, frost-like dendritic vasculitis and optic neuroretinitis.
