Objective:To evaluate the diagnostic value of native T1 mapping in differentiating Oxford classification (MEST-C) scores in patients with IgA nephropathy.Methods:In this prospective study, patients who underwent both T1 mapping and renal biopsy at the First Medical Center of the Chinese PLA General Hospital between April 2023 and October 2024 were consecutively enrolled. Two radiologists, blinded to clinical and pathological information, measured renal T1 mapping parameters, including cortical T1 (cT1), medullary T1 (mT1), the corticomedullary difference (ΔT1), and the corticomedullary ratio (T1 ratio). Clinical and renal biopsy data based on the Oxford classification from patients with IgA nephropathy were collected. The Oxford classification includes five indicators: Mesangial hypercellularity (M), Endocapillary hypercellularity (E), Segmental glomerulosclerosis or adhesion (S), Tubular atrophy/interstitial fibrosis (T), and Cellular or fibrocellular crescents (C). Spearman correlation analysis was applied to evaluate the associations between MEST-C scores and T1 parameters. The diagnostic performance of T1 parameters for discriminating among scores of the Oxford classification was analyzed using the receiver operating characteristic (ROC) curve.Results:A total of 124 patients with IgA nephropathy were included in this study [66 males, 58 females; age 19-70 years, 39 (30, 51) years]. Except for the E indicator, M, S, T, and C were significantly correlated with renal T1 values ( ρ=0.177-0.414, all P<0.05). cT1 showed the best diagnostic efficacy for the S score, with an area under the curve (AUC) of 0.798, a sensitivity of 68.7%, and a specificity of 88.0%. The best T1 parameter for differentiating the T score was the T1 ratio, with an AUC of 0.687, a sensitivity of 57.9%, and a specificity of 79.1%. Conclusion:Native T1 mapping can be used for the non-invasive assessment of the S and T scores in the Oxford classification of patients with IgA nephropathy.

Objective　To explore the relationship between the levels of serum lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and angiopoietin-like protein 8 (ANGPTL8) and the degree of neurological deficit and prognosis of patients with acute watershed cerebral infarction.Methods　From June 2018 to July 2021,105 patients with acute watershed cerebral infarction accepted by our hospital were enrolled as the research group,the NIHSS scale was used to evaluate the degree of neurological deficit,and the patients were divided into mild neurological deficit group and moderate-severe neurological deficit group;the modified Rankin scale was used to evaluate the prognosis of the patients,and they were grouped into a good prognosis group and a poor prognosis group;another 100 healthy subjects were enrolled as the control group,the serum levels of LOX-1 and ANGPTL8 of subjects in each group were detected,and the differences between groups were compared.Receiver operating characteristic (ROC) curve was drawn to analyze the evaluation value of serum LOX-1 and ANGPTL8 levels for the degree of neurological deficit and prognosis in patients with acute watershed cerebral infarction.Results　The levels of serum LOX-1 and ANGPTL8 in the study group were obviously higher than those in the control group,the levels of serum LOX-1 and ANGPTL8 in the moderate to severe neurological deficit group were obviously higher than those in the mild neurological deficit group,and the levels of serum LOX-1 and ANGPTL8 in the poor prognosis group were also obviously higher than those in the good prognosis group (P<0.05).The area under the curve (AUC) of serum LOX-1 and ANGPTL8 combined to assess moderate to severe neurological deficit in patients with acute watershed cerebral infarction was 0.894,which was greater than that of LOX-1 (0.763) and ANGPTL8 (0.852) alone (P<0.05);the AUC of the two combined assessment of acute watershed cerebral infarction patients with poor prognosis was 0.932,which was greater than that of LOX-1 and ANGPTL8 alone (P<0.05).Conclusion　Serum LOX-1 and ANGPTL8 levels are up-regulated in patients with acute watershed cerebral infarction,and the combination of the two has a higher efficacy in evaluating the degree of neurological deficit and prognosis of patients.

Objective: To compare the treatment effect of surgical clipping and endovascular coil embolization for aneurysmal subarachnoid hemorrhage (aSAH) in the elderly. Methods: Elderly patients with aSAH (aged >65 years) treated in Shanghai Pudong Hospital from January 2009 to December 2017 were enrolled retrospectively. They were divided into craniotomy clipping group and endovascular intervention group according to the treatment strategy. The Glasgow Outcome Scale was used for short-term outcome assessment at discharge, 4-5 were defined as good outcome, and 1-3 were defined as poor outcome. Long-term follow-up was performed to assess clinical outcomes using the modified Rankin Scale, 0-2 was defined as good outcome and 3-6 were defined as poor outcome. The clinical and imaging information, perioperative complications, short-term and long-term clinical outcomes, and long-term imaging outcomes were compared between the two groups. Multivariate logistic regression analysis was used to assess the independent influencing factors of clinical outcomes. Results: A total of 68 elderly patients with aSAH were enrolled. Of these, 47 (69.1%) received endovascular coil embolization and 21 (30.9%) underwent microsurgical clipping. There were no significant differences between the two groups in the incidence of perioperative complications, short-term and long-term adverse outcomes, and imaging recurrence rate. Multivariate logistic analysis showed that smoking (odds ratio [OR] 36.319, 95% confidence interval [CI] 3.530-373.640; P=0.003), modified Fisher grade (OR 20.406, 95% CI 2.022-205.964; P=0.011) and World Federation of Neurological Societies (WFNS) grade (OR 4.686, 95% CI 1.012-21.692; P=0.048) were the independent risk factors for short-term poor outcomes in elderly patients with aSAH. Conclusion Both endovascular intervention and microsurgical clipping are safe and effective treatments for elderly patients with aSAH.

Nuclear factor(NF)-κB is widely expressed in various types of tissue cells. Abnormal activation of NF-κB signaling pathway can lead to the initiation and progression of asthma,chronic ob?structive pulmonary disease(COPD)and other lung inflammatory diseases,but inhibition of its activity can effectively alleviate the occurrence and development of these diseases. In this paper ,we review biological characteristics of NF-κB,role of NF-κB signaling in asthma,COPD and other inflammatory lung diseases,and potential application of NF-κB inhibitors in clinical treatment of these inflammatory lung diseases. It will provide a valuable reference for further study on pathogenesis,prevention,and control of lung inflammatory diseases.

Objective To investigate the feasibility, safety and effectiveness of stent-assisted coil embolization for the treatment of intracranial wide-necked aneurysms. Methods The clinical and imaging data of the patients with intracranial wide-necked aneurysm treated with stent-assisted coil embolization were analyzed retrospectively. Results A total of 200 patients with 205 aneurysms were enrolled. The mortality was 1. 5% and the disability rate was 1. 0% at discharge. One hundred seventy-seven patients were followed up for 16-51 months. The modified Rankin Scale scores: 0 in 174 cases, 2 in 2 cases, 4 in 1 case. Eleven patients (5. 5% ) had perioperative complications, including intraoperative bleeding in 3 cases, postoperative bleeding in 3 cases, postoperative cerebral infarction in 2 cases, coil protrusion in 2 cases, and postoperative epileptic seizure in 1 case. Univariate analysis showed that there were significant differences in the proportions of male patients (9. 1% vs. 5. 3% ; χ2 = 4. 42, P = 0. 026), hypertension (54. 5% vs. 23. 3% ; χ2 = 5. 42, P = 0. 03) and stent prior to coil implantation (54. 5% vs. 85. 1% ; χ2 = 3. 54, P =0. 021) between the complication group and the noncomplication group. Multivariate logistic regression analysis showed that the pre-stenting was an independent protective factor for surgery-related complications (odds ratio [OR] 0. 208, 95% confidence interval [CI] 0. 055-0. 791; P = 0. 021), and hypertension was an independent risk factor for surgery-related complications (OR 4. 380, 95% CI 1. 170-16. 399; P = 0. 028). The imaging follow-up of 167 aneurysms was obtained, including 26 recurrent aneurysms (15. 6% ). Univariate analysis showed that there was significant difference in the aneurysm site (anterior circulation aneurysms: 73. 1% vs. 89. 1% ; posterior circulation aneurysms: 26. 9% vs. 10. 6% ; χ2 = 5. 09, P = 0. 033) and size (giant aneurysms: 7. 7% vs. 0. 7% ; large artery aneurysm: 65. 4% vs. 29. 1% ; small aneurysms:26. 9% vs. 70. 2% ; χ2 = 20. 77, P < 0. 001) between the recurrence group and the nonrecurrence group. Multivariate logistic regression analysis showed that large aneurysms (OR 6. 057, 95% CI 2. 296-5. 983; P <0. 001), giant aneurysms (OR 25. 260, 95% CI 1. 903- 335. 267; P = 0. 014 ), and posterior circulation aneurysms ( OR 3. 184, 95% CI 1. 028- 9. 857; P = 0. 045 ) were the independent risk factors of postoperative recurrence. Conclusions Stent-assisted coil embolization is one of the effective methods for the treatment of complex wide-neck aneurysms. Hypertension and coils prior to stenting are the independent risk factors for perioperative complications, and larger aneurysm size and aneurysms in the posterior circulation are the independent risk factors for postoperative recurrence.

Venous thromboembolism includes deep venous thrombosis and pulmonary embolism. It is a more common and preventable complication in neurology. The prevention of venous thromboembolism is an important component in the treatment of the patients with cerebral hemorrhage. The measures include mechanical prevention and drug prevention. The mechanical prevention measures include intermittent pneumatic compression devices and pressure gradient elastic stockings. Studies have suggested that anticoagulants also plays an important role in the prevention of venous thromboembolism. The comprehensive and systematic understanding of the prevention of venous thromboembolism wil help to guide the clinical therapy and improve the outcomes of patients after primary intracerebral hemorrhage.
