Abstract
Objective: To identify objective markers between the Parkinson variant of multiple system atrophy (MSA-P) and Parkinson's disease (PD). Methods: Retrospective analysis was performed on 10 patients with MSA-P, 15 patients with PD, and 15 healthy control group during the period from August 2016 to February 2019 in Baoshan Branch of Shanghai First People's Hospital.We combined the novel tract based spatial statistics (TBSS) and region of interest (ROI) analyses for the first time to investigate three groups with diffusion tensor imaging. By TBSS, we performed pairwise comparisons of mean diffusivity and fractional anisotropy (FA) maps. The clusters with significant differences between MSA-P and PD were used as ROIs for further analyses. Results: FA values in the left anterior thalamic radiation(ATR) (ROI values were 0.371(0.287-0.535), 0.472(0.390-0.594), 0.473(0.388-0.555); P values were 0.008, 0.008) and left superior longitudinal fasciculus (SLF)(ROI values were 0.397(0.291-0.469), 0.456(0.338-0.560), 0.473(0.427-0.530); P values were 0.013,<0.001) were significantly decreased in MSA-P compared with PD or controls, and significantly correlated with clinical data((r =-0.807, P =0.005),(r =-0.455, P =0.022)). Conclusion: Our findings indicate the abnormalities of left ATR and left SLF as specific biomarkers for differential diagnosis.

Abstract
Objective: To evaluate the drug-drug interactions and the tolerability of combined medication between yimitasvir phosphate capsules with sofosbuvir tablets, omeprazole magnesium enteric-coated tablets, and rosuvastatin calcium tablets in healthy volunteers. Methods: A randomized, open, and continuous administration design was used in trial 1 (yimitasvir phosphate capsules with sofosbuvir tablets). 28 subjects were randomly divided into two groups. A non-randomized, open design was used in trial 2 (yimitasvir phosphate capsules with omeprazole magnesium enteric-coated tablets), and included 42 subjects divided into three groups. The open design method was used in trial 3 (yimitasvir phosphate capsules with rosuvastatin calcium tablets), and included 14 subjects. The plasma concentrations of yimitasvir phosphate, sofosbuvir and their main metabolites GS-331007, omeprazole and rosuvastatin were validated by a liquid chromatography/tandem mass spectrometry (LC-MS/MS). The pharmacokinetic parameters were calculated by Phoenix winNonlin software. Results: (1) in trial 1, after single and co-administration, the 90% CI of sofosbuvir C(max) and AUC(0-tau) geometric mean ratio (GMR) were 152.0% (118.0% ~ 197.0%) and 230.0% (184.0% ~ 287.0%), with an increase of 52.0% and 130.0% compared to single dose of sofosbuvir, respectively. The 90% CI of GS-331007 C(max) GMR was 74.0% (67.5% ~ 81.2%) and reduced by 26% compared to single dose of sofosbuvir. (2) in trial 2, the 90% CI of C(max) GMR after yimitasvir single or co-administration at the same time, with a 4-hours interval, or with a 12- hours interval were 68.9% (44.5% ~ 106.7%) , 64.0% (43.8% ~ 93.6%) and 56.4%(38.9% ~ 81.9%), and the 90% CI of AUC(0-t) GMR were 68.6% (46.5% ~ 101.2%), 68.3% (47.6% ~ 98.0%) and 60.5% (41.8% ~ 87.5%), respectively. Compared with single dose of yimitasvir, the C(max) and AUC(0-t) were decreased by 31.1% and 31.4%, 36.0% and 31.7%, 43.6% and 39.5%, respectively. (3) In trial 3, after single and co-administration, the 90% CI of rosuvastatin C(max) and AUC(0-72) GMR were 172.4% (153.6% ~ 193.5%) and 158.0% (144.3% ~ 172.9%), respectively, with an increase of 74.9% and 60.5% compared to single dose of rosuvastatin. There were no serious adverse events and adverse events leading to withdrawal from the trial. Conclusion: Yimitasvir phosphate capsules have drug-drug interactions with sofosbuvir tablets, omeprazole magnesium enteric-coated tablets, and rosuvastatin calcium tablets.

Abstract
Effective laboratory markers for the estimation of disease severity and predicting the clinical progression of coronavirus disease-2019 (COVID-19) is urgently needed. Laboratory tests, including blood routine, cytokine profiles and infection markers, were collected from 389 confirmed COVID-19 patients. The included patients were classified into mild (n = 168), severe (n = 169) and critical groups (n = 52). The leukocytes, neutrophils, infection biomarkers [such as C-reactive protein (CRP), procalcitonin (PCT) and ferritin] and the concentrations of cytokines [interleukin (IL)-2R, IL-6, IL-8, IL-10 and tumor necrosis factor (TNF)-α] were significantly increased, while lymphocytes were significantly decreased with increased severity of illness. The amount of IL-2R was positively correlated with the other cytokines and negatively correlated with lymphocyte number. The ratio of IL-2R to lymphocytes was found to be remarkably increased in severe and critical patients. IL-2R/lymphocytes were superior compared with other markers for the identification of COVID-19 with critical illness, not only from mild but also from severe illness. Moreover, the cytokine profiles and IL-2R/lymphocytes were significantly decreased in recovered patients, but further increased in disease-deteriorated patients, which might be correlated with the outcome of COVID-19. Lymphopenia and increased levels of cytokines were closely associated with disease severity. The IL-2R/lymphocyte was a prominent biomarker for early identification of severe COVID-19 and predicting the clinical progression of the disease.

Abstract
BACKGROUND Mild cognitive impairment (MCI) is a transitional stage of cognitive function between normal aging and dementia. Substantial variations in the prevalence of MCI in different countries have been studied including China. In this study, we established a prediction system to assess the risk of MCI among the elderly in China. METHODS The Rothman-Keller model was conducted on the basis of the risk factors of MCI obtained by the combined results of a meta-analysis. The accuracy of the model was verified using actual population data. RESULTS A total of 1826 subjects as a verification set were enrolled in this study in February 2019. There were statistically significant differences in the combined results of 10 risk factors including hypertension, diabetes, educational level, hyperlipidemia, smoking, physical exercise, living alone, stroke, drinking and heart disease (P<0.05). The area under the curve (AUC) of the actual data and the predictive results of this model was 0.859 (95%CI: 0.812-0.906, P<0.05), the sensitivity was 86.6% and the specificity was 76.5%. CONCLUSIONS This model performs an effective prediction that may be applied to the primary prevention for patients with MCI, helping to reduce the risk of MCI.

Abstract
T cells and dendritic cells (DCs) that are positive for the tissue-resident marker CD103 play a vital role in antitumor immunity. In this study, multiplexed immunohistochemistry was applied to stain CD103 and the T-cell marker CD8 as well as the DC marker CD11c on formalin-fixed, paraffin-embedded oral squamous cell carcinoma (OSCC) tissues. Then, the density of CD103+CD8+ and CD103+CD11c+ tumor-infiltrating lymphocytes (TILs) in the intratumoral and stromal regions was calculated, and the correlation of CD103+CD8+ TIL and CD103+CD11c+ TIL density with OSCC patient prognosis was analyzed. The results revealed that CD103+CD8+ TILs and CD103+CD11c+ TILs were abundant in the stromal region and that increased stromal CD103+CD8+ TIL and intratumoral CD103+CD11c+ TIL density indicated a favorable prognosis. Moreover, we freshly isolated TILs from OSCC samples and performed flow cytometry to verify that CD103+CD8+ TILs display a tissue-resident memory T-cell (Trm) phenotype, and we discriminated CD103+CD11c+ TILs from tumor-associated macrophages.

Abstract
MicroRNAs (miRNAs) are involved in the gastric carcinogenesis and progression. Here, we confirmed that miR-483 was frequently decreased in gastric cancer patients. The expression levels of miR-483 were negatively correlated with tumor stage, node metastasis and stromal invasion. Log-rank tests demonstrated that low expression of miR-483 was strongly correlated with poor overall survival in patients with gastric cancer. Moreover, ectopic expression of miR-483 remarkably suppressed gastric cancer cell proliferation by enhancing cell apoptosis and significantly inhibited the invasion of gastric cancer cells, while low expression of miR-483 exhibited the opposite effect. Bioinformatics analysis revealed that OGT was a potential target of miR-483, and miR-483 inhibited the expression level of OGT mRNA by direct binding to its 3'-untranslated region (3'UTR). Expression of miR-483 was negatively correlated with OGT in gastric cancer tissues. In addition, modulation of miR-483 expression could affect the global cellular protein O-GlcNAcylation in gastric cancer cells. Furthermore, silencing of OGT counteracted the effects of miR-483 repression, while its overexpression reversed tumor inhibitory effects of miR-483. In conclusion, our study revealed that miR-483 functions as a tumor suppressor by inhibiting proliferation, invasion and protein O-GlcNAcylation of gastric cancer via targeting OGT, and that miR-483 may serve as prognostic or therapeutic target for gastric cancer.

Abstract
Objective: To compare the prognostic efficiency of Lugano staging, TNM staging and Musshoff staging systems in patients with primary gastrointestinal diffuse large B-cell lymphoma(PGI-DLBCL) and investigate its clinical features and prognosis. Methods: The clinical data of 110 patients with PGI-DLBCL in Tianjin Medical University Cancer Institute and Hospital from May 2008 to August 2017 was retrospectively analyzed. The stage of lymphoma was assessed following Lugano staging, TNM staging and Musshoff staging systems respectively. The prognostic value was compared mainly according to the situation of 5-year overall survival (OS)and the influence of different clinical features on prognosis of patients was also investigated. Results: The median age of the whole study was 55(range 17-92) years old. With a median follow-up time of 36 (range 1-115) months, the median progression-free survival (PFS) was 35 (range 0-86) months, and the median overall survival was 37 (range 2-104) months. The 5-year OS rate of Lugano stagingⅠ, Ⅱ, Ⅲ and Ⅳ were 77.6%, 73.4%, 69.7%, 12.2% (χ(2)=63.395, P<0.001) respectively. The 5-year OS rate of TNM staging Ⅰ, Ⅱ, Ⅲ and Ⅳ were 77.6%, 75.9%, 25.0%, 9.3% (χ(2)=65.802, P<0.001) respectively. The 5-year OS rate of Musshoff stagingⅠ, Ⅱ, Ⅲ and Ⅳ were 84.5%, 68.4%, 25.0%, 9.3% (χ(2)=66.966, P<0.001) respectively. By Cox multiple-factors analysis, Lugano staging system was the only independent prognosis risk factor for PFS (HR=4.987, 95%CI: 1.421-17.498, P=0.009) and OS (HR=5.659, 95%CI: 1.563-20.485, P=0.008) of PGI-DLBCL. Univariated analysis revealed that the factors affecting PFS and OS of patients with PG-DLBCL include B-symptom, Eastern Cooperative Oncology Group performance status (ECOG PS), the number of extranodal lesions, serum lactate dehydrogenase (LDH), International prognostic index (IPI) score, staging and therapeutic regimen(all P values of PFS and OS<0.05). Patients with PG-DLBCL who received chemotherapy alone showed a better survival than others (PFS P=0.004; OS P<0.001); the factors affecting PFS and OS of patients with PI-DLBCL include β2-microglobulin(β2-MG), serum albumin(ALB) levels, LDH and staging (all P values of PFS and OS<0.05). Therapeutic regimen didn't affect those patients' survival (PFS P=0.661, OS P=0.720). The additional use of Rituximab failed to improve the survival of patients with PG-DLBCL and PI-DLBCL respectively (all P values of PFS and OS>0.05). Conclusions: Compared with TNM staging and Musshoff staging systems, Lugano staging system provides the best prognostic value in PFS and OS for patients with PGI-DLBCL. Accompany with B-sympto, higher ECOG PS score, more extranodal lesions, increased LDH, higher IPI score and later period are negative factors for PG-DLBCL. Increased β2-MG and LDH, lower ALB level and later period are negative factors of PI-DLBCL.

Abstract
Objective: To investigate the clinical effect of bile reinfusion combined with enteral nutrition support before surgery for hilar cholangiocarcinoma. Methods: A retrospective analysis of patients with hilar cholangiocarcinoma who underwent surgical treatment at Nanjing Drum Tower Hospital Hepato-biliary-pancreatic Surgery Department from July 2010 to August 2017 was completed.A total of 52 cases were finally enrolled in our study.All the patients included, on the basis of whether they received preoperative drainage and bile reinfusion, were divided into non-drainage group(n=15) and drainage group(n=37). Differences of clinical indicators, including operation time, intraoperative bleeding and serum liver function index levels at day 1, 3, 7 postoperative, postoperative complications(liver failure, biliary fistula, pleural effusion, peritoneal effusion, abdominal cavity infection, death in hospital), tumor classification, R0 resection, postoperative hospitalization time between the 2 groups were analyzed. At the same time, in the drainage group, patients were divided into non-enteral nutrition subgroup(n=13) and enteral nutrition subgroup(n=24) according to whether they received enteral nutrition before operation. The normal distribution data of the group was statistically analyzed by independent sample t test, the non-normal distribution data of the group was statistically analyzed by rank-sum test. The count data was statistically analyzed by non-calibration and correction of the square test. Results: There was no statistically significant difference in general infomation such as age, gender, and serum liver function between non-drainage group and drainage group(P>0.05). There was no statistically significant difference in general information such as age, gender, and serum liver function between non-enteral nutrition group and enteral nutrition group(P>0.05). The rate of vascular resection and reconstruction(33.3%) and operating time(10.8(2.2)h) in drainage group were both higher than those in non-drainage group(6.7% and 8.3(3.0)h), the differences were both statistically significant(χ(2)=4.397, Z=1.595; both P<0.05). The level of AST at the 7th day after surgery in drainage group(32.8(17.3)U/L) was significantly lower than that in non-drainage group(55.0(64.7)U/L), the difference was statistically significant(Z=-2.212, P<0.05). The level of TBil at 1st day after surgery in drainage group(43.6(91.2)μmol/L) was lower than that in non-drainage group(91.2(188.4)μmol/L), the difference was statistically significant(Z=-2.150, P<0.05). The rate of pancreatoduodenectomy(25.0%) and average operating time(11.1(1.3)h) in the enteral nutrition group were both higher than those in the non-enteral nutrition group(0, 9.0(2.6)h). The differences were both statistically significant(χ(2)=3.879, Z=-2.693; P<0.05). The average level of AST at the 1st day after surgery in enteral nutrition group(396.4(268.3)U/L) was significantly lower than that in non-enteral nutrition group(642.5(341.1)U/L), the difference was statistically significant(Z=-2.483, P<0.05). The average level of TBil at the 1st, 3th day after surgery in enteral nutrition group(38.8(21.5)μmol/L and 30.0(25.6)μmol/L) were both lower than those in non-enteral nutrition group(60.9(75.2)μmol/L and 46.5(50.0)μmol/L), the differences were both statistically significant(Z=-2.416, -2.026; P<0.05). The level of CRP at 1st, 3th day after surgery((41.9±31.1)mg/L, (50.8±31.4)mg/L)in enteral nutrition subgroup was lower than that in non-enteral nutrition subgroup((64.4±33.6)mg/L, (74.1±35.3)mg/L), the differences were both statistically significant(t=1.456, 1.675; P<0.05). Conclusion: Based on the present study , there is no effective improvement on postoperative recovery using bile reinfusion combined with nutrition support before R0 resection of hilar cholangiocarcinoma.

Abstract
Objective: To study the airway inflammation feature difference in the patients with occupational pulmonary thesaurosis induced by iron. Methods: Induced sputum samples were obtained from 20 healthy men, 20 patients with stable asthma, 25 patients with occupational pulmonary thesaurosis induced by iron. Differential cell counts in induced sputum were examined. The levels of supernatant IL-8 were measured by ELISA. Results: The pulmonary function result was normal in the patients with pulmonary thesaurosis., their FVC (4.1±1.2) L was similar to FVC (4.3±0.9) L in mal group; but their FEV(1.0) (2.9±0.9) L、FEV(1)/FVC (71.9%±5.4%) were lower than normal group's FEV(1.0) (3.2±0.7 L) 、FEV(1.0)/FVC (79.2%±9.9%) , and were hirher than asthma group's FEV(1) (2.5±0.8) L and FEV(1.0)/FVC (68.7%±6.1%) . In induced sputum, macrophages percentage in patients with pulmonary thesaurosis (54.3%±9.7%) was higher than asthma group and normal group (48.4±6.4, 51.9±7.3, P<0.05) , neutrophils percentage in patients with pulmonary thesaurosis group (43.9%±7.6%) was higher than asthma group and normal group (41.3%±7.1%, 39.8%±6.9%, P<0.05) , eosinophils percentage in patients with pulmonary thesaurosis group (0.3%±0.1%) was lower than asthma group (2.8±0.3, P<0.05) , lymphocytes percentage in patients with pulmonary thesaurosis group (2.0%±0.4%) was lower than asthma group (4.7±0.6, P<0.05) ; the sputum levels of IL-8 in patients with pulmonary thesaurosis group (914.7±24.3) pg/ml was higher than asthma group and normal group (747.9%±16.8 pg/ml, (405.4±13.7) pg/ml, P<0.05) . Conclusion: Macrophages and IL-8 may play an important role in the pathogenesis of airway inflammation after long-term inhalation of iron and its compounds, the airway function in patients of occupational pulmonary thesaurosis was found damaged.

Abstract
Objective: To explore the signal pathway of M2-type polarization induced by Mycobacterium tuberculosis (MTB)-specific peptide E7. Methods: Monocyte-macrophages were divided into blank control group, M1 positive stimulus group [co-stimulated with lipopolysaccharide and gamma interferon (IFN-γ)], M2 positive group(co-stimulated with IL-4 and IL-13), and E7 experimental group (with MTB-specificity polypeptide E7 stimulated). The expression of M1 type markers CD(16), IL-6, TNF-α and M2 type markers CD(163), CD(206), IL-10 were detected at 12, 18, 24 and 36 h. Furthermore, peroxisome proliferators-activated receptors-γ (PPAR-γ) blocker was used in the blank control group, M2-positive stimulus group and E7 experimental stimulus group. T test was used to compare the expression of PPAR-γ and CD(163) before and after the addition of blockers. Results: Compared with the positive control group and the blank control group, the expression of TNF-α in the E7 experimental group gradually reached the peak when macrophages were stimulated for 18 h(the relative expression was 20.02), and then the expression of TNF-α gradually decreased and the expression of CD(163) increased. The expression of CD(163) peaked at 24 h (the relative expression was 2.44). After adding the inhibitor, the expression of PPAR-γ in E7 stimulation group was lower than before blocking (before blocking 0.94±0.06, after blocking 0.69±0.09, P=0.028). CD(163) expression level was significantly lower than that before blocking (before blocking 3.95±0.61, after blocking 2.87±0.20, P=0.047). Conclusion: The MTB-specific peptide E7 induced differentiation of macrophages into M2 type, a process that may be involving PPAR-γ in just another kinase-signal transducer and activator of transcription pathway.

Abstract
Multiple sclerosis (MS) is the leading cause of non-traumatic neurological disability in the United States in young adults, but current treatments are only partially effective, making it necessary to develop new, innovative therapeutic strategies. Myelin-specific interleukin (IL)-17-producing T helper type 17 (Th17) cells are a major subset of CD4 T effector cells (Teff ) that play a critical role in mediating the development and progression of MS and its mouse model, experimental autoimmune encephalomyelitis (EAE), while regulatory T cells (Treg ) CD4 T cells are beneficial for suppressing disease. The IL-6/signal transducer and activator of transcription 3 (STAT-3) signaling pathway is a key regulator of Th17 and Treg cells by promoting Th17 development and suppressing Treg development. Here we show that three novel small molecule IL-6 inhibitors, madindoline-5 (MDL-5), MDL-16 and MDL-101, significantly suppress IL-17 production in myelin-specific CD4 T cells in a dose-dependent manner in vitro. MDL-101 showed superior potency in suppressing IL-17 production compared to MDL-5 and MDL-16. Treatment of myelin-specific CD4 T cells with MDL-101 in vitro reduced their encephalitogenic potential following their subsequent adoptive transfer. Furthermore, MDL-101 significantly suppressed proliferation and IL-17 production of anti-CD3-activated effector/memory CD45RO+ CD4+ human CD4 T cells and promoted human Treg development. Together, these data demonstrate that these novel small molecule IL-6 inhibitors have the potential to shift the Teff : Treg balance, which may provide a novel therapeutic strategy for ameliorating disease progression in MS.

Abstract
OBJECTIVE Fatty liver may induce various complications including chronic hepatitis or liver cirrhosis, and is frequently occurred in obesity individuals. Advanced glycosylation end products (AGEs) were known to play a critical role in multiple liver diseases. This study, therefore, aimed to study the effect of AGEs on obesity, related liver cirrhosis and inflammation, on an obesity fatty liver rat model. MATERIALS AND METHODS A total of 60 Sprague Dawley (SD) rats were randomly divided into control, model and AGEs inhibitor groups (n=20 each). AGEs level, body weight and liver function were examined in each animal, followed by hematoxylin-eosin (HE) staining to detect the pathological change of liver. Further Real-time PCR and enzyme-linked immunosorbent assay (ELISA) were employed to detect inflammatory cytokine levels including tumor necrosis factor (TNF)-α and interleukin (IL)-6. RESULTS AGEs level was significantly elevated in obesity fatty liver model rats, which also had higher total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) levels, along with deteriorated liver function and higher TNF-α and IL-6 levels. The application of AGEs inhibitor aminoguanidine significantly improved liver functions and lower TNF-α or IL-6 levels when compared to the model group (p<0.05 in all cases). CONCLUSIONS Obesity fatty liver can promote AGEs level, further causing pathological changes and increased secretion of inflammatory cytokines. The inhibition of AGEs can improve the metabolism of fatty acids, decrease inflammatory cytokines and benefit the treatment of obesity fatty liver.

Abstract
OBJECTIVE Asian melanoma patients, predominantly comprised of acral and mucosal subtypes, might not benefit from immunotherapy and targeted therapy as much as Caucasian patients. Novel treatment strategies are demanded after conventional treatment failure. This was a prospective, single-arm, and single-center dose escalation study to investigate the safety and preliminary efficacy of apatinib combined with temozolomide in heavily treated advanced melanoma patients. METHODS Patients were sequentially admitted to four dose-escalating groups of apatinib and temozolomide (three cases in each group) using a traditional 3 + 3 dose escalation design method. RESULTS Twelve patients were enrolled between December 2016 and August 2017. Most patients with an acral or mucosal primary origin progressed after immunotherapy or targeted therapy. Dose escalation had been completed without dose-limiting toxicity. Common adverse events included hypertension, hand-foot syndrome, proteinuria, neutropenia, nausea, and fatigue. All adverse events were grade 1 or 2, while the maximum tolerated dose was not reached. Up to January 2018, 1 patient achieved partial response, 9 experienced stable disease, and 2 exhibited progressive disease. The objective response rate and disease control rate were 8.3% and 83%, respectively. CONCLUSIONS In conclusion, apatinib combined with temozolomide was well tolerated and has demonstrated efficacy in advanced melanoma patients.
