Nonspecific orbital inflammation(NSOI)is an orbital inflammation that is not associated with an infection. Even though it's often considered the most common diagnosis in orbital biopsies, it's still an exclusionary diagnosis that means systemic illnesses and other possible causes have to be ruled out. Though it is always an excluded clinical diagnosis, acute orbital symptoms such discomfort, exophthalmos, periorbital edema, chemosis, diplopia, and vision impairment are commonly associated with NSOI. Clinical diagnosis and management of NSOI provide a substantial difficulty. There are presently no recognized diagnostic criteria or standard treatment strategy for NSOI, and the clinical symptoms and histological features show significant variation. This guide was formulated under the auspices of the Ocular Oncology Committee of the Opthalmology Branch of the Chinese Medical Doctor Association, Opthalmology Committee of International Association of Intelligent Medicine, Opthalmology Committee of International Association of Translational Medicine making a detailed summary of the definition, classification, diagnosis and treatment of the NSOI, with a view to aiding clinicians to improve diagnostic efficiency and formulate a better treatment plan for patients.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.

Objective To explore the effect of different post-processing methods of total spinal CT angiography(CTA)for displaying spinal dural arteriovenous fistula(SDAVF).Methods Total spinal CTA data of 55 patients with SDAVF were retrospectively analyzed.Traditional post-processing of original CTA images(modified tissue growth boneless volume rendering[VR]and full-range axial maximum intensity projection[MIP])were performed,while the axial,sagittal and coronal MIP reconstructions,axial,sagittal and coronal VR reconstructions,as well as axial,sagittal and coronal MIP+VR reconstructions of original CTA images on lesion layers were completed,respectively.Taken digital subtraction angiography(DSA)as the gold standards,a 5-point scale was used to subjectively evaluate the effect of displaying the location,the range and feeding artery of fistula shown on CTA images based on different post-processing methods.Results No significant difference of subjective score of location nor feeding artery of fistula was found among axial MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images reconstructed using other post-processing methods(all P＜0.05).Meanwhile,no significant difference of subjective scores of the range of SDAVF was detected among sagittal MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images obtained using other post-processing methods(all P＜0.05).Conclusion The location and feeding artery of SDAVF could be observed based on axial MIP,VR and MIP+VR reconstructions of the total spinal CTA,while sagittal MIP,VR and MIP+VR reconstructions were conducive to display the range of SDAVF.Combination of multiple post-processing methods was helpful for comprehensive understanding the composition and range of SDAVF.

To establish a rapid Akabane virus(AKAV)antibody detection method in animals,the re-combination AKAV N protein was expressed by the expression system of Escherichia coli,puri-fied from the supernatant,and used to immunized New Zealand White rabbits.The polyclonal anti-body against AKAV N protein had a titer of 1∶8.192×107 and showed good reactivity.After opti-mizing the reaction conditions,an AKAV double antigen sandwich ELISA antibody detection method was established.This method can detect AKAV antibody in a variety of animals including cattles,sheep and goats.The method had no cross-reactivity with the positive serum of BTV,EHDV,BEV and PRV with the intra-and inter-batch coefficients of variation less than 10％.Com-pared with the AKAV blocking ELISA kit,the sensibility of the method was increased by 8-16 folds with a compliance rate of 93.33％and the κ value of 0.864.These results showed that the double antigen sandwich ELISA displayed strong specificity,high sensitivity and repeatability,which could provide technical suport for detection,the prevention and control of AKAV.

ObjectiveTo explore the influence of excessive weight gain during pregnancy in pre-pregnancy overweight and obese women on pregnancy outcomes and neonatal conditions， and to provide scientific evidence for formulating weight management strategies before and during pregnancy and prevent adverse pregnancy outcomes. MethodsClinical data of 2 172 parturients collected from a community in Huangpu District from 2017 to 2021 were retrospectively analyzed， and they were divided into pre-pregnancy overweight and obesity group （n=530）， normal pre-pregnancy weight group（n=937）， and underweight pre-pregnancy group（n=705） according to maternal precursor body mass index （BMI）. Based on their weight gain during pregnancy，the parturient were divided into moderate gestational weight gain （MGWG） group and excessive gestational weight gain （EGWG） group. Meanwhile， the pregnancy and neonatal outcomes such as postpartum hemorrhage， puerperal infection， placental abruption， premature rupture of membranes， mode of delivery， premature birth， stillbirth， fetal distress， admission to the intensive care unit （ICU）， macrosomia， and Apgar score， were recorded. Then the differences in pregnancy and neonatal outcomes between groups were compared. The effects of pre-pregnancy BMI and gestational weight gain on pregnancy outcomes and neonatal conditions was retrospectively analyzed. ResultsThe pre-pregnancy overweight and obese group had higher proportions of placental abruption， premature rupture of membranes， cesarean section， premature birth， fetal distress， and macrosomia compared to the normal pre-pregnancy weight group and the underweight pre-pregnancy group， with Apgar scores lower than the normal pre-pregnancy weight group and the underweight pre-pregnancy group （all P<0.05）. The EGWG group had higher proportions of postpartum hemorrhage， placental abruption， premature rupture of membranes， cesarean section， premature birth， fetal distress， admission to the ICU， and macrosomia than the MGWG group （all P<0.05）. In the pre-pregnancy overweight and obese group， the EGWG group had higher proportions of placental abruption， premature rupture of membranes， premature birth， fetal distress， admission to the ICU， and macrosomia than the MGWG group， with lower Apgar scores than the MGWG group （all P<0.05）. In the normal pre-pregnancy weight group， the EGWG group had higher proportions of placental abruption， premature rupture of membranes， premature birth， fetal distress， admission to the ICU， and macrosomia than the MGWG group （all P<0.05）. In the pre-pregnancy overweight and obese group， the EGWG group had higher proportions of premature rupture of membranes， cesarean section， premature birth， fetal distress， and macrosomia than the EGWG group in the normal pre-pregnancy weight group（all P<0.05）. Logistic regression analysis showed that EGWG in pre-pregnancy overweight and obese women was a risk factor for placental abruption （OR=2.971， 95%CI： 1.098‒8.042）， premature rupture of membranes （OR=4.662， 95%CI： 2.798‒7.770）， cesarean delivery （OR=1.375，95%CI： 1.260‒2.541）， premature birth （OR=4.249， 95%CI： 2.384‒7.573）， fetal distress （OR=3.238， 95%CI： 1.589‒6.598）， admission to the ICU （OR=3.010， 95%CI： 1.265‒7.164）， and macrosomia （OR=5.437， 95%CI： 3.392‒8.716） （all P<0.05）. ConclusionExcessive gestational weight gain in pre-pregnancy overweight and obese women is a risk factors for placental abruption， premature rupture of membranes， cesarean section， premature birth， fetal distress， admission to the ICU， and macrosomia.
