Abstract
OBJECTIVE The function of MDR3 is important in bile acid transport. The miRNAs can suppress the expression of gene through combining mRNA of target gene. The regulation about MDR3 mediated by FXR or PPARα in cholestasis is clear, but the mechanism through miRNA is hardly reported. We aimed to find out the miRNA, which could suppress MDR3 expression and the significance of this connection in cholestasis. PATIENTS AND METHODS We measured hsa-miR-378a-5p expression level in liver tissues from 20 patients with cholestasis and 15 patients without cholestasis by quantitative PCR. We also tested the level of clinical features of the same group. HepG2 cell lines were performed experiments to discover the connection between hsa-miR-378a-5p and MDR3, including transient transfection, RNA and protein extraction, qPCR, Western blotting and luciferase reporter assay. RESULTS A significant decrease of miR-378a-5p was observed in obstructive cholestasis patient liver tissues compared to control group. We also find that the miR-378a-5p expression is correlated to several clinical features, which are important biomarkers in cholestatic liver injury. Then we predicted that MDR3 may be the target gene of miR-378a-5p through miRanda v3.3a. We programed the transient transfection of mimics and inhibitor on HepG2 cell lines, and detected the mRNA and protein expression of MRP2, MRP3 and MDR3. The results suggested that miR-378a-5p could negatively regulate MDR3 expression in both mRNA and protein expression level, and this regulation is specific. We didn't find same regulation in MRP2 and MRP3. Dual luciferase assays proved this regulation is mediated by a direct binding between miR-378a-5p and CDS of MDR3. CONCLUSIONS We found that hsa-miR-378a-5p expression was down-regulated in cholestatic liver tissues, compared to control liver tissues. Transient transfection and luciferase reporter assay in HepG2 cell lines results suggest that hsa-miR-378a-5p can directly combine MDR3 mRNA and suppress MDR3 protein expression. The down-regulated hsa-miR-378a-5p may cause a protective alteration through up-regulating MDR3 expression in cholestasis.

Abstract
Periodontitis is twice as prevalent in diabetics as in nondiabetics, and type 2 diabetes (T2D)-associated periodontitis is severe in many cases due to the altered and aberrant functions of bone cells in hyperglycemic conditions. Therefore, developing an effective method to halt the disease process, as well as restore and regenerate lost alveolar bone to reserve the natural teeth in diabetics, is critically important. In the current study, we applied a newly discovered adiponectin receptor agonist AdipoRon (APR) in experimental periodontitis in diabetic animal models and demonstrated the underlying molecular mechanisms. We found that when APR systemically quenched the blood sugar level in diet-induced obesity (DIO) diabetic mice, it reduced osteoclast numbers and alveolar bone loss significantly due to APR's inhibition on osteoclast differentiation shown in our in vitro studies. APR also decreased the production of proinflammatory molecules CC chemokine ligand 2 and interleukin 6 in diseased gingival tissues. On the other hand, APR promoted alveolar bone regeneration through enhancing osteogenic differentiation and decreasing stromal cell-derived factor 1 in the bone marrow that facilitates stem cell migration. Same results were achieved by APR treatment of periodontitis induced in adiponectin (APN) knockout mice, indicating the ability of APR to activate the endogenous APN receptors to exert osteoanabolic effects. In summary, our study supports the notion that APR could be used as an effective multipronged approach to target T2D-associated periodontitis.

Abstract
BACKGROUND AND PURPOSE Alberta Stroke Program Early CT Score (ASPECTS) was devised as a systematic method to assess the extent of early ischemic change on noncontrast CT (NCCT) in patients with acute ischemic stroke (AIS). Our aim was to automate ASPECTS to objectively score NCCT of AIS patients. MATERIALS AND METHODS We collected NCCT images with a 5-mm thickness of 257 patients with acute ischemic stroke (<8 hours from onset to scans) followed by a diffusion-weighted imaging acquisition within 1 hour. Expert ASPECTS readings on DWI were used as ground truth. Texture features were extracted from each ASPECTS region of the 157 training patient images to train a random forest classifier. The unseen 100 testing patient images were used to evaluate the performance of the trained classifier. Statistical analyses on the total ASPECTS and region-level ASPECTS were conducted. RESULTS For the total ASPECTS of the unseen 100 patients, the intraclass correlation coefficient between the automated ASPECTS method and DWI ASPECTS scores of expert readings was 0.76 (95% confidence interval, 0.67-0.83) and the mean ASPECTS difference in the Bland-Altman plot was 0.3 (limits of agreement, -3.3, 2.6). Individual ASPECTS region-level analysis showed that our method yielded κ = 0.60, sensitivity of 66.2%, specificity of 91.8%, and area under curve of 0.79 for 100 × 10 ASPECTS regions. Additionally, when ASPECTS was dichotomized (>4 and ≤4), κ = 0.78, sensitivity of 97.8%, specificity of 80%, and area under the curve of 0.89 were generated between the proposed method and expert readings on DWI. CONCLUSIONS The proposed automated ASPECTS scoring approach shows reasonable ability to determine ASPECTS on NCCT images in patients presenting with acute ischemic stroke.

Abstract
BACKGROUND AND PURPOSE Thrombus characteristics identified on non-contrast CT (NCCT) are potentially associated with recanalization with intravenous (IV) alteplase in patients with acute ischemic stroke (AIS). Our aim was to determine the best radiomics-based features of thrombus on NCCT and CT angiography associated with recanalization with IV alteplase in AIS patients and proximal intracranial thrombi. MATERIALS AND METHODS With a nested case-control design, 67 patients with ICA/M1 MCA segment thrombus treated with IV alteplase were included in this analysis. Three hundred twenty-six radiomics features were extracted from each thrombus on both NCCT and CTA images. Linear discriminative analysis was applied to select features most strongly associated with early recanalization with IV alteplase. These features were then used to train a linear support vector machine classifier. Ten times 5-fold cross-validation was used to evaluate the accuracy of the trained classifier and the stability of the selected features. RESULTS Receiver operating characteristic curves showed that thrombus radiomics features are predictive of early recanalization with IV alteplase. The combination of radiomics features from NCCT, CTA, and radiomics changes is best associated with early recanalization with IV alteplase (area under the curve = 0.85) and was significantly better than any single feature such as thrombus length (P < .001), volume (P < .001), and permeability as measured by mean attenuation increase (P < .001), maximum attenuation in CTA (P < .001), maximum attenuation increase (P < .001), and assessment of residual flow grade (P < .001). CONCLUSIONS Thrombus radiomics features derived from NCCT and CTA are more predictive of recanalization with IV alteplase in patients with acute ischemic stroke with proximal occlusion than previously known thrombus imaging features such as length, volume, and permeability.

Abstract
H9N2 subtype avian influenza virus (AIV) was the highly contagious pathogen which has caused severe losses in the poultry industry throughout China in recent years. Using current epidemic viruses as vaccine was an effective way to prevent infection of H9N2 subtype AIV. In this study, a total of 23 H9N2 subtype AIV strains were isolated in 200 samples from 13 provinces of China during 2012-2016. The sequencing and phylogenetic analysis of the hemagglutinin gene sequence of the isolation strains showed that 22 isolation strains were clustered to h9.4.2.5 lineage, while only 1 belonged to h9.4.2.6. The data of cross-HI, neutralization and cross-immune protection shown that the A/chicken/Hunan/HN/2015 (HN) and A/chicken/Shandong/SD/2014 (SD) strains as vaccine could effectively protect present viruses infection compared with other strains. These results indicated that current epidemic viruses were mainly belong to h9.4.2.5 lineage and HN and SD strains as candidate vaccine strains were potentiality for the protection of present H9N2 subtype AIV infection.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to analyse the clinical and prognostic features of myelin oligodendrocyte glycoprotein (MOG) antibody-associated demyelination with different onset phenotypes. METHODS A total of 52 MOG-IgG-seropositive patients were divided into four groups: (i) optic neuritis (ON) at onset (MOG-ON+ , n = 23), (ii) transverse myelitis (TM) at onset (MOG-TM+ , n = 12), (iii) pure brain symptoms at onset (MOG-ON- -TM- , n = 14) and (iv) both ON and TM at onset (n = 3). This final group was not included in further analyses. Data were collected through medical records and regular follow-up. RESULTS Median age at presentation was 24 (range, 3-63) years in the whole cohort (50% female). MOG-ON- -TM- patients had the youngest age of onset across the three groups. Patients with MOG-TM+ tended to relapse more frequently and had a longer interval to first relapse than was observed in MOG-ON+ and MOG-ON- -TM- patients. High MOG-IgG titres were associated with increased cerebrospinal fluid leukocytes. The likelihood of harbouring transient, low MOG-IgG titres was higher in the MOG-TM+ group than in the other groups. After a median disease duration of 20 months, most but not all cases had a favourable outcome, with 8% developing severe visual deficit, 2% becoming wheelchair-dependent and 6% developing cognitive impairment. The onset phenotype appeared to be an important predictor of disability type. Having high MOG-IgG titres (odds ratio, 0.168, P = 0.027) or female gender (odds ratio, 0.270, P = 0.067) was associated with a lower likelihood of complete recovery. CONCLUSIONS Onset phenotype may influence long-term presentation, MOG-IgG status as well as outcome. Further large and prospective studies are needed to better clarify the clinical implications of the first demyelinating event.

Abstract
Objective: To investigate the clinical features of patients involved with both malignant tumors and neuromyelitis optica spectrum disorders (NMOSD). Methods: The clinical data of 473 patients with NMOSD admitted into the Third Affiliated Hospital of Sun Yat-sen University and the Department of Neurology, Affiliated Hospital of Guizhou Medical University from June 2012 to March 2017 were retrospectively analyzed. Eleven NMOSD patients complicated with malignant tumors were screened out (3 with breast cancer, 2 with cervical cancer, 2 with rectal cancer, 2 with leukemia, 1 with nasopharyngeal carcinoma, 1 with thyroid cancer). Fifty patients without NMOSD were included as controls. Results: Most of the NMOSD patients were complicated by low-moderately differentiated squamous cell carcinoma/adenocarcinoma, mainly seen in breast, reproductive system, digestive system and hematological system. In terms of sex ratio and autoantibodies, the NMOSD patients with and without malignant tumors showed no significant difference. However, comparing to the patients without malignant tumor, the ones with malignant tumor showed a tendency of lower rate of initial brain symptoms and relapse rate, while with older onset age, higher initial EDSS score, protein content in cerebrospinal fluid (CSF), higher rates of initial symptom resulted from the focus of posterior region of the medulla and of significant image focus. Of the 8 NMOSD patients who diagnosed as malignant tumors in our hospital, 2 with breast cancer and 1 with cervical cancer had a good prognosis (follow-up EDSS score <3). All the 3 patients received aggressive surgery and chemotherapy treatment. However, the other 5 patients had poor prognosis (follow-up EDSS score ≥3 points). All the 11 patients received anti-tumor therapy, 4 patients had first NMOSD attack after anti-tumor treatment and no relapse. Only one case from the remaining 7 patients had relapse; Among the 9 patients received immunosuppressive therapy, 7 patients had no relapse, and 8 cases maintained stable; while, among all the 9 patients received immunosuppressive agents and anti-tumor therapy, only one case had relapse. Conclusions: There are some differences in the clinical features between the NMOSD patients with malignant tumors and the NMOSD patients without malignant tumors. Immunosuppressive therapy can improve the prognosis of patients with NMOSD and tumor, without increasing the risk of malignant tumor. The pathological type, staging and antitumor therapy may influence the prognosis of NMOSD. NMOSD patients with malignant tumor could be treated with anti-tumor and immunosuppressive agents if needed.

Abstract
Objective: To evaluate the efficacy and safety of mycophenolate mofetil (MMF) in neuromyelitis optica spectrum disorder (NMOSD). Method: From September 2014 to February 2017, NMOSD patients with seropositive aquaporin4-IgG was enrolled through a multicenter, prospective study, and the annual recurrence rate (ARR), Expanded Disability Status Scale (EDSS) and MMF-related side effects before and after MMF treatment were compared. Results: Ninety patients were enrolled in the study. After being treated for a median of 12 months (1-30 months), the median ARR decreased from 1.1 pre-MMF to 0 post-MMF (P<0.001), and the median EDSS score decreased from 4.0 pre-MMF to 3.0 post-MMF (P<0.001). The EDSS score reduced significantly after 90 days' treatment (P<0.05). The main adverse events included the deranged liver enzymes (19%, 17/90), respiratory infection (11%, 10/90), urinary tract infection (6%, 5/90), varicella-zoster infection (6%, 5/90), anemia (6%, 5/90), leucopenia (6%, 5/90), diarrhea (2%, 2/90), hair loss (1%, 1/90); 11% (10/90) patients experienced severe adverse events, and 6% (5/90) patients discontinued MMF. Conclusions: MMF could significantly reduce the ARR and EDSS score of NMOSD. However, awareness on side effects should be raised.

Abstract
BACKGROUND Cystatin C (CysC) is associated with many neurodegenerative disorders and autoimmune diseases, but its relationship with anti-N-Methyl-D-aspartate receptor (anti-NMDAR) encephalitis is unknown. METHODS Serum levels of CysC were determined in 66 patients with anti-NMDAR encephalitis and 115 healthy controls. Of the 66 patients, 30 had a follow-up evaluation at 3 months after admission. Association of CysC with anti-NMDAR encephalitis and its clinical parameters were evaluated in the patients. RESULTS The serum levels of CysC were significantly lower in patients with anti-NMDAR encephalitis than in controls (0.70 ± 0.13 vs 0.83 ± 0.17 mg/mL, P < .001). Disease severity and disease duration were significantly associated with CysC levels. Furthermore, a follow-up evaluation revealed that after treatment anti-NMDAR encephalitis patients had significantly increased serum CysC levels (P < .001) and significantly decreased modified Rankin Scale (mRS) scores (P < .001) compared with before treatment. In addition, a significant negative correlation was observed between the change in CysC levels and the change in mRS scores (r = -.700, P < .001). CONCLUSION Our results show that the serum levels of CysC are associated with anti-NMDAR encephalitis and its clinical parameters and that the changes in CysC levels correlate with therapeutic effect. Therefore, our findings provide new insights into the association between serum CysC and anti-NMDAR encephalitis.

Abstract
The full-field stress distribution of a two-dimensional plain fabric was mapped using micro Raman spectroscopy (MRS) through a novel yarn push-out test, simulating a quasi-static projectile impact on the fabric. The stress-strain relationship for a single yarn was established using a digital image correlation method in a single-yarn tensile test. The relationship between Raman peak shift and aramid Kevlar 49 yarn stress was established using MRS in a single-yarn tensile test. An out-of-plane loading test was conducted on an aramid Kevlar 49 plain fabric, and the yarn stress was measured using MRS. From the full-field fabric stress distribution, it can be observed that there is a cross-shaped distribution of high yarn stress; this result would be helpful in further studies on load transfer on a fabric during a projectile impact.

Abstract
Krabbe disease (KD) is a rare disease caused by the deficiency of β-galactocerebrosidase. This study investigated 22 unrelated Chinese patients, including their clinical presentations, plasma psychosine levels and β-galactocerebrosidase gene mutations. We found the late-onset form of KD present in 82% of the patients in our study, which was more prevalent than in patients from other populations. Plasma psychosine levels were elevated in KD, which were correlated with the severity of clinical presentations. Sanger sequencing identified 8 novel mutations, including 7 missense mutations, p.H253Y, p.S259L, p.P318L, p.F350V, p.T428A, p.L530P, p.G586D, and 1 splicing mutation, c.1251+1G>A. Quantitative real-time polymerase chain reaction (PCR) and multiplex ligation-dependent probe amplification identified a novel exon 12 and 14 deletion, separately. Next generation sequencing, applied at the final step, revealed 2 missense mutant alleles missed using Sanger sequencing. The most common mutation in Chinese population is p.P154H, which accounts for 20.5% of alleles. Consistent with the higher prevalence of the late-onset form of KD, missense mutations predominated in our study, different with the common mutation types in Europe and Japan. This work was the first large-scale study of Chinese KD patients describing their clinical, biochemical and genetic characteristics, which furthered our understanding of this classical neurological lysosomal storage disease.

Methods: The clinical information of patients with ovarian tumor and anti-NMDAR encephalitis in The 3rd Affiliated Hospital of Sun Yat-Sen University and The Zhujiang Hospital of Southern Medical University were collected and analyzed. Results: There were 15 patients were enrolled in this study, with the average age of 24.5±5.0 years old. The most frequent first symptom was psychosis. The main clinical features were psychosis, seizures, conscious disturbance, autonomic dysfunction, dyskinesia, central hypoventilation and impaired memory. Most patients' symptoms were relieved after immunotherapy and surgery. The number of favorable prognosis of patients (mRS score 0-2) with ovariectomy was higher than that of the patients with ovarian cystectomy (5 vs 3). But the difference had no statistical significance (P=0.529). Conclusions: For young female patients with psychosis, we should be alert to the possibility of anti-NMDAR encephalitis and screen for tumor. Treated with immunotherapy and operation, most patients can get a favorable prognosis.

Abstract
Objective: To analyze the clinical characteristics of neuromyelitis optica spectrum disorders (NMOSD) associated with syringomyelia (SML). Methods: The clinical manifestations, laboratory parameters and imaging findings of 7 patients with NMOSD associated with SML during June 2008 to August 2016 from The Third Affiliated Hospital of Sun Yat-sen University were retrospectively analyzed. Results: Six patients were female and 1 was male, with ages ranging from 27-67 years, the course of the disease was 3-12 years, recurrence was 2-7 times, all the patients were cerebrospinal fluid oligoclonal bands (CSF OCB) negative, 5 patients were positive for aquaporin-4-antibody/NMO-IgG. Sensory and motor dysfunction, bowel or bladder dysfunction were the common clinical manifestation, and pain was a significant symptom. Syringomyelia was predominantly located in C4-T10, cavity length 2-6 mm, diameter 0.8-3.6 mm; 5 had lobes involvement and 6 had long segmental spinal cord involvement. Conclusions: NMOSD associated with SML had a high frequency of occurrence in female, with the clinical characteristics of limb pain, easy progression, high recurrence rate and disability rate. The anti AQP4 antibody were commonly seen in these patients. Syringomyelia was predominantly located in the lower cervical and upper thoracic spinal cord, the lobar and longitudinally extensive transverse myelitis were frequently found in patients with NMOSD associated with SML.

Abstract
AIM Differentiation between Crohn's disease (CD) and intestinal tuberculosis (ITB) continues to be difficult. The present study investigated the collagen fibre characteristics of CD and ITB using Masson's trichrome staining, second harmonic generation (SHG) imaging and two-photon excited fluorescence (TPEF) imaging with the aim of distinguishing between them. METHOD The characteristics of collagen fibres in intestinal specimens from patients with CD, ITB and healthy controls were compared using Masson's trichrome staining and SHG and TPEF imaging. RESULTS Masson's trichrome staining showed that the content of collagen fibre (540.92 [139.61-1681.93] vs 236.17 [72.94-1108.32], P < 0.05) and fibre deposits (888.92 [315.89-3172.9] vs 498.98 [38.82-5802.31], P < 0.05) were both higher in ITB than in CD. The content of collagen fibre (594.677 [139.61-1681.93] vs 107.425 [4.66-988.7], P < 0.05) and fibre deposits (1118.4661 [315.89-5802.31] vs 340.575 [29.62-1188.87], P < 0.05) were significantly higher in lesions with granulomata than in those without. The SHG/TPEF images demonstrated that the percentage of fibrosis in ITB was also significantly higher than in CD (P < 0.05), in both surgical (13.363% ± 5.303% vs 8.322% ± 5.078%, P = 0.044) and endoscopic specimens (mean rank 13.5 vs 7.5, P = 0.023). The SHG/TPEF imaging described different distribution patterns of collagen between CD and ITB; in the former this was irregular in clumps while in ITB the collagen was arranged around caseating granulomata. CONCLUSION The evaluation of fibrosis in CD and ITB by Masson's trichrome staining and SHG and TPEF imaging appears to distinguish between these two diseases.

Abstract
Objective: To investigate the clinical features in 44 patients with acute disseminated encephalomyelitis (ADEM). Methods: Consecutive ADEM patients admitted to Neurology Department of the Third Affiliated Hospital of Sun yat-sen University during August 2009 to July 2014 were enrolled.Clinical and laboratory data of the patients were reviewed and analyzed. Results: Forty-four patients with ADEM based on the 2012 criteria were recruited, including 23 male and 21 female; 9 children, 11 teenagers and 24 adults.There were 23 monophasic ADEM (23/44, 52%) and 21 multiphasic ADEM (21/44, 48%). Fourteen patients (31.8%) had definite incentive factors within 2 weeks preceding the disease onset.The commonest presenting symptoms were fever (20/44, 45%), mental disorder (18/44, 41%), disturbance of consciousness (17/44, 39%) and seizure (12/44, 27%). The average EDSS score was (4.3±1.3), and the average mRS score was (2.7±0.9). Abnormal autoimmune antibodies were detected in 10 patients.Two patients were positive for NMO-IgG, and three patients were positive for oligoclonal bands.On MRI scanning, small lesions were observed in 18 of 44 patients (18/44, 41%); large confluent white matter lesions in 10 patients (10/44, 23%); symmetric bithalamic involvement in 12 patients (12/44, 27%). Patients were mainly treated with intravenous corticosteroids (40/44, 90.9%) and immunoglobulin G ( 13/44, 29.5%) in acute phase.Regular follow-up performed in 29 patients (65.9%), and the average follow-up time was (4.2±2.3) year.A monophasic course was found in 10 patients, and multiphasic course in 19 patients.After (2.5±2.3) years, patients with multiphasic ADEM experienced their first clinical relapse, and the relapse frequency was (3.3±1.4). The average EDSS score was (3.9±2.2), and the mRS score was (2.2±1.3) in their latest relapse.In follow-up MRI for (5.3±1.9) years, lesions in 18 patients (62.1%) were partially ameliorated, while 6 patients (20.7%) persisted, and new lesions appeared in 5 patients (17.2%). For the 13 multiphasic patients with regular treatment, intravenous corticosteroids (13/13, 100.0%) and immunoglobulin G (7/13, 53.8%) were still important treatments in the acute phase, while oral steroids (12/13, 92.3%) plus immunosuppressants including azathioprine, tacrolimus, cyclosporine and rituximab were chosen in the remission phase. Conclusions: ADEM is not uncommon in adults, presenting with multiphasic course, encephalopathy features and disseminated lesions on MRI.As it shows very heterogeneous characteristics, ADEM is best viewed as a "syndrome" rather than a specific disorder.

Abstract
INTRODUCTION Commonly encountered foreign bodies are remnants from surgical procedures and ingested materials. Rarely, the latter cause stone formation in the biliary tract. CASE HISTORY We describe a 51-year-old female who underwent choledoduodenostomy and who presented with abdominal distension caused by multiple stones in the bile ducts within the liver (hepatolithiasis) and an intact celery stalk. Hepatolithiasis was demonstrated by ultrasonography and computed tomography of the abdomen. The celery stalk was not confirmed until exploration of the biliary duct. CONCLUSIONS Here, we describe, for the first time, an intact, undigested celery stalk in the biliary tract which induced hepatolithiasis. We believe that choledochojejunostomy favoured reflux of the celery stalk from the duodenum into the biliary tract.
