Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Objective To investigate the correction between the fertilization rate of in vitro fertilization(IVF)and sperm parameters.Methods This retrospective study included 327 cases undergoing IVF procedures in the Center for Reproductive Medicine of Chenz-hou First People's Hospital,who were divided into a low fertilization group(fertilization rate＜30％,n=19)and normal fertilization group(fertilization rate≥30％,n=308)based on the assessment standards of quality control data in the embryology laboratory of our center.The basic information of males,embryo information and related sperm parameters were collected,and the correction between sperm parameters and the fertilization rate was analyzed by Pearson correlation.The influencing factors of the fertilization rate were ana-lyzed by binary logistic regression,and the area under the receiver operating characteristic(ROC)curve(AUC)was performed to ana-lyze the predictive value of low fertilization rate.Results The sperm acrosin activity,percentage of spermatozoa with normal morpholo-gy and sperm DNA fragmentation index(DFI)were the relevant factors affecting the fertilization rate,and the correlation coefficients were 0.168,0.306,and-0.243,respectively(all the P＜0.05).Logistic regression analysis showed that all the three indicators were independent factors affecting the fertilization rate of IVF,and the multivariate logistic equation was as follows:estimated fertilization rate=-2.561+0.035 ×acrosin activity+2.066×percentage of sperm with normal morphology-1.51×sperm DFI.The areas under the ROC curve(AUC)of acrosin activity,percentage of sperm with normal morphology,sperm DFI and the combination of them were 0.806,0.889,0.827 and 0.899,respectively.The corresponding cut-off values for the Yuden index were 61.20 μIU/106 sperm,2.98％,27.50％and-21.32,respectively.The sensitivity of acrosin activity,percentage of sperm with normal morphology,sperm DFI and the combination of three indicators for the prediction of low fertilization rate were 95.70％,76.90％,68.40％,64.30％,and their specificity were 43.50％,94.70％,87.70％,100.00％,respectively.The combination of three indicators showed the best prediction ef-ficiency.Conclusion Acrosin activity,percentage of sperm with normal morphology and sperm DFI should be the independent factors to predict the fertilization rate of IVF,and the multivariate logistic equation can be used as a reference to predict the fertilization rate of IVF.

Purpose To investigate whether ketogenic diet(KD)can promote cognition by regulating brain metabolism and neuroinflammation in Alzheimer's disease model mice.Materials and Methods Twenty male APP/PS1 mice were randomly assigned to either a KD group(APP/PS1+KD)or a regular diet group(APP/PS1),with 10 mice in each group.Additionally,10 wild-type C57BL/6 male mice served as the control group.The APP/PS1+KD group was fed with a ketogenic feed,the APP/PS1 group received a regular diet,and the control group was maintained on standard chow for a duration of 4 months.Blood ketone levels of mice were monitored after 4 weeks and 4 months of continuous feeding.Cognitive function was assessed via the morris water maze.18F-FDG and 18F-DPA-714 micro PET/CT were performed to evaluate the effects of KD on glucose metabolism and neuroinflammation across various brain regions in the Alzheimer's disease mice.Following PET/CT imaging,brain tissue samples were collected,and the hippocampal Cal region was selected for paraffin sectioning to detect the expression of glial fibrillary acidic protein and ionized calcium-binding adapter molecule 1 through immunofluorescence analysis.Results In the Morris water maze in the fourth month,compared with the control group,the APP/PS1 group had a significantly longer escape latency on days 3-4(P＜0.05 or P＜0.01).Compared with the control group,the APP/PS1 group showed a significant decrease in relative 18F-FDG uptake in brain regions such as the striatum,hippocampus,dorsal thalamus,central gray matter,superior colliculus,olfactory bulb,and midbrain(P＜0.01,P＜0.05).Compared with the APP/PS1 group,the APP/PS1+KD group showed a significant increase in relative 18F-FDG uptake in the hippocampus and dorsal thalamus(P＜0.01).Compared with the control group,the APP/PS1 group showed a significant increase in relative uptake of 18F-DPA-714 in brain regions such as the striatum,hippocampus and hypothalamus(P＜0.05 or P＜0.001).Compared with the APP/PS1 group,the APP/PS1+KD group decreased the relative uptake of 18F-DPA-714 in the hippocampus(P＜0.01).Compared with the control group and APP/PS1+KD group,the fluorescence intensity of glial fibrillary acidic protein and ionized calcium-binding adapter molecule 1 protein in the brain(hippocampus)of APP/PS1 group mice was significantly increased(both P＜0.01).Conclusion KD has the potential to ameliorate cognitive and behavioral deficits in APP/PS1 mice by enhancing brain metabolism and attenuating neuroinflammation.

Objective:To explore the current status of readiness for young and middle-aged maintenance hemodialysis (MHD) patients to return to work and analyze its influencing factors, with the aim of providing reference for the evaluation and intervention of patients returning to work.Methods:From October to December 2022, convenience sampling was used to select 425 patients from six hospitals in the urban area of Yangzhou as the subject. A cross-sectional survey was conducted using the General Information Questionnaire, Readiness for Return-To-Work Scale (RRTWS), Distress Disclosure Index (DDI) and Perceived Social Support Scale (PSSS). Binary Logistic regression was used to analyze the influencing factors of returning to work.Results:Among 425 young and middle-aged patients undergoing MHD, 105 (24.7%) returned to work, of which 79 (75.2%) were in the uncertain maintenance stage and 26 (24.8%) were in the active maintenance stage. 320 did not return to work, including 148 (46.3%) in the pre-intention stage, 86 (26.9%) in the intention stage, 42 (13.1%) in the action preparation self-evaluation stage, and 44 (13.8%) in the action preparation behavior stage. Age, per capita monthly income of the family, number of comorbidities, level of self-disclosure, and level of perceived social support were factors that affected patients' readiness to return to work.Conclusions:The rate of young and middle-aged MHD patients returning to work needs to be improved. The return of patients to work is influenced by multiple factors. Medical and nursing staff should focus on patients who are old, have low per capita monthly income of the family, and have a large number of comorbidities. Targeted interventions and guidance should be provided to patients, such as self-disclosure training and improving their perceived social support, in order to increase the rate of patients returning to work rate.

Objective:To explore the clinical features and pathogenic causes of a Chinese Han family with Wagner syndrome, and to analyze the relationship between VCAN gene mutation and patient phenotype. Methods:The method of family pedigree investigation was adopted.A Chinese Han family with Wagner syndrome in 3 generations including 13 family members was collected in Xiamen Eye Center of Xiamen University in January 2020, and 5 patients from 3 generations were diagnosed.All members underwent a comprehensive medical history collection and routine ophthalmological examinations, including visual acuity, intraocular pressure, slit lamp microscopy, and ophthalmoscopy to analyze the condition of anterior segment and fundus.Anterior segment photography, fundus photography, optical coherence tomography and ultrasound biological microscopy were carried out in the proband and some patients to analyze the condition of anterior segment, fundus and anterior chamber angle.The peripheral venous blood of all family members was collected for genomic DNA extraction, and pathogenic gene variation analysis for verification was through high-throughput target region capture sequencing and Sanger sequencing.Variants were scored using the American College of Medical Genetics and Genomics (ACMG) guidelines, and the structure and function of variants were predicted through PredictProtein.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xiamen Eye Center of Xiamen University (No.MR-35-22-002800).Written informed consent was obtained from each subject.Results:The Chinese pedigree with Wagner syndrome was in accordance with autosomal dominant inheritance pattern, and all patients had no history of systemic disease or other abnormal manifestations.The common ophthalmic features of the patients were abnormal suspensory ligament, premature cataract, vitreous cavity, vitreous condensation, veil-like proliferative membrane in the vitreous cavity, retinal choroid atrophy and thinning, tractional retinal detachment, and retinal pigmentation.The proband had binocular cataract surgery, and binocular intraocular lens dislocation occurred after the operation.Genetic analysis revealed that a heterozygous splice site variation c.9265+ 1G>A in the VCAN gene in this family was co-segregated with the disease phenotype and graded as a likely pathogenic variant by the ACMG guidelines.This variant base pair substitution could cause the formation of a protein product with 1 754 amino acids shorter, resulting in insufficient haploid dosage and severe reduction of glycosaminoglycan attachment sites, making the versican protein dysfunctional. Conclusions:It is the first time to report a Chinese family with Wagner syndrome in China, and it is confirmed that the family has a heterozygous variation in the VCAN gene c.9265+ 1G>A by molecular genetic analysis.

Objective To compare the effects of caffeine citrate and aminophylline combined with naloxone in the treatment of premature infants with apnea.Methods From March 2015 to March 2017,140 premature infants with apnea who were treated in neonatal intensive care unit in Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were selected in the research.The children were randomly divided into the study group and the control group according to the digital table,with 70 cases in each group.The control group was treated with aminophyl-line combined with naloxone,and the observation group was treated with caffeine citrate.The adverse reaction of children during the treatment was recorded,and the level of apnea was evaluated after treatment.The blood gas index of children before and after 48h treatment was compared,the mortality rate of the children was counted,and the incidence of brain injury during the 1 year follow -up was analyzed.Results After treatment for 48h,the level of PaO2in the two groups was significantly higher [study group: (10.54 ±0.41) kPa,control group: (9.66 ± 0.39) kPa] than those before treatment[study group: (7.18 ±0.26) kPa,control group: (7.21 ±0.24) kPa],and the level of PaCO2[study group: (5.31 ±0.24) kPa,control group: (5.82 ±0.25) kPa]was significantly lower than those before treatment[study group: (6.83 ±0.28) kPa,control group: (6.77 ±0.30) kPa](t＝19.153,13.624,11.271,7.304;P＝0.000,0.000,0.000,0.000),and the level of PaO2in the study group was significantly higher than that in the control group,and the level of PaCO 2in the study group was significantly lower than that in the control group(t＝6.029,4.327;P＝0.000,0.000).The overall effective rate of apnea therapy in the study group (92.86%) was significantly higher than 77.14%in the control group (χ2＝4.509,P＝0.034).The mortality rate(1.43%) and the incidence rate of brain injury (0.00%) of the study group were significantly lower than those of the control group (10.00%and 7.14%)(χ2＝4.773,5.185;P＝0.029,0.023).The incidence rate of adverse reactions (30.00%) of the study group was significantly lower than 50.00%of the control group (χ2＝5.833,P＝0.016).The endometri-al thickness of the study group was significantly lower than that of the control group (P＜0.05).The rate of ovulation success(87.84%) and pregnancy success rate (45.94%) of the study group were significantly higher than those of the control group(72.97%and 28.39%)(χ2＝5.189,4.890;P＝0.023,0.027).The rate of abortion(8.82%) of the study group was significantly lower than 33.33%of the control group (χ2＝5.242,P＝0.022).During the period of treatment,the incidence rate of adverse drug reactions (6.77%) of the study group was not significantly different from 8.11%of the control group (χ2＝0.098,P＝0.754).Conclusion Compared with aminophylline combined with naloxone treatment,caffeine citrate can significantly improve the blood gas status of apnea preterm infants,improve the overall curative effect of apnea,prevent the occurrence of neonatal death and brain injury,and reduce the adverse reactions of the children during the treatment.It is worthy of clinical application.
