Objective:To investigate the value of central vein sign (CVS) and iron deposition on quantitative susceptibility imaging (QSM) of 3.0 T MRI in differentiating multiple sclerosis (MS) from neuromyelitis optica spectrum disease (NMOSD).Methods:This study was a retrospective study. A total of 54 MS patients and 49 NMOSD patients were enrolled from July 2018 to December 2020 in People′s Hospital of Leshan and the First Affiliated Hospital of Chongqing Medical University. All patients underwent conventional MRI and three-dimensional enhanced T 2*-weighted angiography (3D-ESWAN), and ESWAN-filtered phase and QSM were reconstructed from 3D-ESWAN data. First, brain lesions of MS and NMOSD were screened on proton density (PD)-T 2WI, and then the location of lesions, CVS and nodular/annular iron deposition were observed on phase and QSM images. The χ 2 test was used to compare the differences in intracranial lesion location, CVS and iron deposition between MS and NMOSD patients. Receiver operating characteristic curve and area under the curve (AUC) were used to assess the efficiency of CVS and QSM iron deposition to differentiate MS from NMOSD. Results:A total of 968 MS lesions were observed in 54 MS patients, of which CVSs were found in 354 lesions and 227 CVSs were located around the lateral ventricles, 117 in deep white matter (DWM) and 10 in the cortex/subcortex; 372 lesions showed nodular iron deposition, and 193 lesions ring iron deposition on QSM. Totally 247 brain lesions were observed in 41 of 48 patients with NMOSD, of which CVSs were found in 4 lesions and 1 located around the lateral ventricle, 3 located in the DWM; 3 lesions showed nodular iron deposition on QSM. There were significant differences in cortex/subcortex lesions, CVS and iron deposition between MS and NMOSD patients (χ 2 were 29.33, 115.66 and 258.21, respectively, all P<0.001). The AUC of CVS for differentiating MS from NMOSD was 0.941 (95%CI 0.887-0.994), with a sensitivity of 96.3% and a specificity of 91.8%; the AUC of iron deposition for differentiating MS from NMOSD was 0.969 (95%CI 0.930-1.000), with a sensitivity of 100% and a specificity of 93.9%. Conclusion:CVS and iron deposition on 3.0 T MRI are distinct radiologic features of MS lesions from those of NMOSD lesions, and have certain value in the differential diagnosis.

Objective:To explore the alteration of structural network, cognitive scores in patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, as well as the relationship between cognitive impairment and changes of structural networks in patients with NMDAR encephalitis.Methods:This study was a retrospective study. A total of 39 patients with anti-NMDAR encephalitis were recruited as the autoimmune encephalitis group (AE group) from the First Affiliated Hospital of Chongqing Medical University between September 2012 to December 2019, and 32 healthy volunteers with normal results of routine head MR examinations and no history of central nervous system diseases were recruited as the health control group (HC group). There were 16 males and 23 females, aged from 13 to 66 (34±15) years, with duration of disease from 11 to 110 (31±20) days in AE group, and there were 16 males and 23 females, aged from 13 to 66 (34±15) years in HC group. All subjects underwent diffusion tensor imaging (DTI) scan and cognitive function evaluation. The brain structural networks of two groups were constructed by deterministic fiber tracking techniques, and the differences of global topological properties [clustering coefficient (C p), shortest path length (L p), local efficiency (E loc), global efficiency (E glob), normalized C p (γ), normalized L p (λ), small-worldness (σ)] and local topological properties between two groups were analyzed by the graph theory approch. The correlations between characteristics of brain structural networks and cognitive function scores were further analyzed. Results:There was no significant difference in age and gender distribution between the AE group and HC group ( P>0.05). The C p [0.005(0.004, 0.007)], γ (1.76±0.13), λ (0.51±0.03) and σ value (1.57±0.13) of AE group were decreased when compared with HC group [the values were 0.007(0.004,0.017), 2.13±0.63, 0.55±0.06 and 1.73±0.36 each] ( Z=-939.00, t=-3.58, t=-4.16, t=-2.58, P<0.05). Compared with HC group, nodal efficiencies in the left middle frontal gyrus (orbital part), left and right supplementary motor areas, left olfactory cortex, left gyrus rectus, bilateral insula, left postcentral gyrus, left paracentral lobule and right heschl gyrus were changed ( P<0.05). There were five identical hub regions which contains the left middle occipital gyrus, bilateral supplementary motor areas and precuneus in both groups. However, in the AE group, three hub regions of the left middle occipital gyrus and bilateral middle temporal gyrus were reduced, and the left precentral gyrus was increased as hub region. The nodal efficiencies of the left supplementary motor areas ( r=0.393, P=0.013), right supplementary motor areas ( r=0.384, P=0.016) and left paracentral lobule ( r=0.356, P=0.026) were positively correlated with the montreal cognitive assessment scores. Conclusion:The white matter is extensively impaired in anti-NMDAR encephalitis patients and the changes of topological properties in several brain regions are correlated with cognitive decline.

Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the central nervous system whose clinical manifestations and diagnostic criteria are non-specific and absence of golden criteria when diagnosing. Magnetic resonance imaging (MRI) can not only observe the focal lesions of demyelination, but also evaluate microstructural damages and iron deposition in the white/gray matter in MS patients by applying various developing sequences. MRIs play an irreplaceable role in revealing pathological evolution, prognosis and monitoring after treatment of MS patients. This paper reviewed the clinical value and application of MRIs for the MS patients in recent years.

Objective:To explore the curative effect of surgical treatment for Crohn′s disease (CD), to investigate the timing of surgical intervention and the choice of surgical methods.Methods:From January 1, 2016 to August 31, 2020, at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, the clinical data of 123 patients with CD and receiving surgical treatment were retrospectively analyzed, which included the type of lesion, the location of lesion, clinical manifestation, surgical method, preoperative inflammatory and nutritional indicators, postoperative recovery of digestive tract function, and the development and treatment of postoperative complications. CD was diagnosed according to Consensus opinion on diagnosis and treatment of inflammatory bowel disease ( Beijing 2018). Patient was classitied according to the Montreal Classification. Postoperative complications were graded according to the Clavien-Dindo Criteria. Mann-Whitney U test was used for statistical analysis. Results:Among 123 patients, according to the Montreal classification, two cases (1.6%) were diagnosed at ≤16 years old (type A1), 66 cases (53.7%) were diagnosed at 17 to 40 years old (type A2), and 55 cases (44.7%) were diagnosed at >40 years old (type A3). The lesions were 52 cases (42.3%) of terminal ileum (L1) type, 20 cases (16.3%) of colon (L2) type, and 51 cases (41.5%) of ileocolon (L3) type. Four cases (3.2%) were non-stenosis and non-penetrating (B1) type, 87 cases (70.7%) were stenosis (B2) type, and 32 cases (26.0%) were penetrating (B3) type. Eighteen patients (14.6%) underwent emergency surgery due to complete intestinal obstruction (10 cases), gastrointestinal perforation (five cases), gastrointestinal bleeding (two cases), and rectovesical fistula complicated with septic shock (one case). One hundred and five patients (85.4%) received selective surgery due to poor conservative treatment effects. 51 cases (41.5%) underwent traditional open surgery and 72 cases (58.5%) underwent laparoscopic surgery. Nineteen patients (15.4%) received temporary or permanent ostomy. The preoperative C reactive protein level of patients with emergency surgery was higher than that of patients undergoing selective surgery ((39.23±24.13) mg/L vs. (11.48±2.68) mg/L), while the levels of plasma albumin (ALB) and pre-ALB were lower than those of patients receiving selective surgery ((29.90±10.60) g/L vs. (38.38±8.30) g/L, (146.00±125.49) mg/L vs. (209.06±61.19) mg/L), and the differences were statistically significant ( Z=9.603, 8.754 and 7.111, all P<0.01). During the follow-up, a total of 23 cases (18.7%) developed postoperative complications, including one case of postoperative intra-abdominal hemorrhage and underwent re-operation (Clavien-Dindo grade Ⅲ complication); four cases of anastomotic leakage after operation; six cases of postoperative paralytic ileus; 11 cases of surgical site infection, all of which were Clavien-Dindo grade Ⅱ complications, and one case of deep venous thrombosis of lower extremity. No patient with severe intraoperative complication was observed, and no patients died during the operation or hospitalization. The postoperative exhaust time of patients was (3.2±1.4) d, the time of open fluid diet was (5.8±0.8) d, the length of hospital stay was (18.0±14.1) d, and the length of postoperative hospital stay was (11.2±8.8) d. Conclusions:The concept of multidisciplinary collaboration should be emphasized in the treatment of CD. Surgical treatment can effectively control the complications and improve the quality of life of patients, but the timing of operation and the choice of surgical methods should be decided prudently after perioperative treatment, multi-disciplinary participated and regulation of the internal environment. The standardized and targeted treatments for the surgical difficulties of inflammatory bowel disease should be conducted.
