Patients with primary membranous nephropathy(PMN)tend to develop thrombosis,especially in the early phase of the disease.The pathogenesis of thrombosis is multifactorial,with hypoalbuminemia being widely regarded as an inde-pendent risk factor.Other factors include proteinuria,M-type phospholipase A2 receptor antibody,and D-dimer.Although prophy-lactic anticoagulation therapy is frequently used in clinical practice to prevent thrombosis in PMN patients,there are still many un-resolved issues regarding the optimal prevention of thrombosis in this condition.The timing of prophylactic anticoagulation,the threshold of serum albumin level,and the choice of treatment regimen are still lacking consensus.This article reviewed the relevant literature on these topics,aiming to establish a standard for thrombosis prevention and treatment for this population in the future and provide guidance for clinical practice.

Objective:To investigate interleukin (IL)-36 expression in patients with myasthenia gravis (MG), and to study the modulatory function of IL-36 on regulatory T cells (Tregs) and Th17 cells in MG patients.Methods:Fifty-one MG patients (MG group) and 25 healthy controls (control group) were enrolled in this study in Xinxiang Central Hospital between July 2016 and August 2021. Peripheral blood was collected. Plasma and peripheral blood mononuclear cells (PBMCs) were isolated. Plasma IL-36α, IL-36β, IL-36γ, IL-36RA, IL-35, and IL-17 levels were measured by enzyme-linked immunosorbent assay. The percentages of Tregs and Th17 cells were measured by flow cytometry. Forkhead box protein P3 (FoxP3) and retinoid-related orphan receptor gamma t (RORγt) mRNA expressions were measured by real-time polymerase chain reaction. PBMCs or purified Tregs from MG patients were stimulated with recombinant IL-36β (5 ng/ml). Changes of Tregs and Th17 cell percentages, IL-35 and IL-17 secretions, FoxP3 and RORγt mRNA expressions, as well as immunosuppressive activity of Tregs were analyzed.Results:There were no statistically significant differences of IL-36α, IL-36γ, or IL-36RA between the control group and the MG group (all P>0.05). IL-36β level was notably higher in the MG group compared with the control group [(73.43±13.91) pg/ml vs (60.91±12.65) pg/ml, t=3.79, P<0.001]. Treg percentage [(4.67±1.33)% vs (6.32±1.81)%, t=4.48, P<0.001], IL-35 [(50.06±7.93) pg/ml vs (65.37±8.90) pg/ml, t=7.59, P<0.001] and FoxP3 mRNA expression (1.03±0.14 vs 1.57±0.46, t=7.78, P<0.001) was lower, while Th17 cell percentage [(1.05±0.15)% vs (0.94±0.21)%, t=2.61, P=0.011], IL-17 [(40.61±13.13) pg/ml vs (33.09±11.48) pg/ml, t=2.44, P=0.017] and RORγt mRNA expression (1.26±0.16 vs 1.03±0.13, t=6.08, P<0.001) was higher in the MG group ( P<0.05). There were no statistically significant differences of above indices between different genders, onset ages, afflicting with thymoma, or different Osserman types (all P>0.05). There were no statistically significant correlations between above indices and quantitative myasthenia gravis (QMG) score (all P>0.05). Recombinant IL-36β stimulation did not affect PBMCs proliferation in MG patients ( P=0.248), and reduced Tregs percentage [(3.05±0.66)% vs (4.18±1.07)%, t=4.23, P<0.001], IL-35 secretion [(48.12±10.93) pg/ml vs (56.96±13.73) pg/ml, t=2.36, P=0.023] and FoxP3 mRNA expression (0.99±0.17 vs 1.18±0.13, t=4.01, P<0.001), but did not affect Th17 cell percentage, IL-17 secretion or RORγt mRNA expression (all P>0.05). Recombinant IL-36β stimulation inhibited immunosuppressive activity of Tregs, which presented as enhanced cellular proliferation [(0.83±0.12)×10 5vs (0.69±0.15)×10 5, t=3.02, P=0.005] and reduced IL-35 secretion [(28.71±10.08) pg/ml vs (37.12±10.47) pg/ml, t=2.39, P=0.023]. Conclusion:Increased IL-36β contributed to the regulation of Tregs/Th17 cell balance probably through inhibition of Tregs function in MG patients.

Hevin is one of the extracellular matrix proteins secreted by astrocytes. Under physiological conditions, Hevin plays an important role in synaptogenesis in the central nervous system (CNS); secreted protein, acidic and rich in cysteine (SPARC) is its homologue and antagonizes the synaptogenic effects of Hevin. In pathological conditions, the expressions of Hevin and SPARC are altered, suggesting their possible roles at synaptic reorganization in various disease process, such as brain injury, Alzheimer's disease, epilepsy and brain tumors; however, the specific mechanism is not totally understood yet. So this paper reviews the mechanism of Hevin/SPARC in CNS synaptogenesis, reorganization and diseases to provide ideas for further research.

Objective:To analyze the site of vestibular nerve damaged in patients with acute vestibular neuritis. Methods:Fifty-seven patients with acute vestibular neuritis were recruited, and each patient underwent caloric irrigation test, video head impulse test(vHIT) and vestibular evoked myogenic potentials(VEMPs). The results were further analyzed. Results:Analysis of abnormal rates of different vestibular function tests: the abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and posterior semicircular canal vHIT were 92.98%, 92.98%, 92.98%, and 52.63%, respectively. The abnormal rate of cervical vestibular evoked myogenic potentials(cVEMP) and ocular vestibular evoked myogenic potentials(oVEMP) were 52.63% and 89.47%. The abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP were significantly higher than posterior semicircular canal vHIT and cVEMP(P<0.01). Combination analysis of different vestibular function tests: there are twenty-six patients(45.61%, superior and inferior vestibular nerve) with abnormal caloric irrigation test, video head impulse test, and VEMPs. There are twenty-five patients(43.86%, superior vestibular nerve) with abnormal caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP. There are 4 patients(7.02%, inferior vestibular nerve) with abnormal posterior semicircular canal vHIT and cVEMP. There are two patients(3.51%, ampullary vestibular nerve) with abnormal caloric irrigation test, horizontal semicircular canal vHIT, and anterior semicircular canal vHIT. The rate of superior and inferior vestibular neuritis and superior vestibular neuritis were significantly higher than inferior vestibular neuritis and ampullary vestibular neuritis(P<0.01). Conclusion:Acute vestibular neuritis subtypes can be divided into four categories: superior and inferior vestibular neuritis, superior vestibular neuritis, inferior vestibular neuritis, and ampullary vestibular neuritis. Video head impulse test can accurately assess the site of vestibular nerve damage in patients with acute vestibular neuritis. In addition, vHIT combined with VEMPs can provide objective evidence for the diagnosis of ampullary vestibular neuritis.
