Here we report the clinical,radiological and neuropathological findings of a patient with tumor-like inflammatory demyelinating diseases of the central nervous system.The patient was a 51-year-old man with a four-month history of inflammatory pseudotumor and no other significant medical history,who presented to our hospital recurrent relapse numbness and weakness of his right extremities,dysarthria and memory deterioration.Brain magnetic resonance imaging(MRI) showed mass focal lesion in white matter of left parietal lobes.The biopsy showed numerous infiltrating macrophages and lymphocytes within the perivascular.The patient responded clinically to corticosteroid and intravenous immunoglobulin(IVIG) therapy.According to the results of the biopsy and the MRI,a diagnosis of inflammatory pseu-dotumor of the central nervous system was made.The vascular dysfunction may act in the pathogenesis of inflammatory pseudotumor of the central nervous system.

Objective To investigate the value of Standardized Swallowing Assessment (SSA) in the screening for aspiration after stroke.Methods 81 patients with acute stroke received examinations of both SSA and Fiberoptic Endoscopic Examination of Swallowing (FEES). The SSA was then measured against the FEES study for sensitivity, specificity, positive predictive value and negative predictive value for aspiration in acute stroke patients. The relation between the Results of SSA and pneumonia post-stroke was analyzed.Results Sensitivity, specificity, positive predictive value and negative predictive value of SSA for aspiration were 95.0%, 53.7%, 66.7% and 91.7%, respectively. The patients with positive result on SSA had a higher incidence of pneumonia ( P＜0.05).Conclusion SSA is a valid and valuable screening tool for aspiration in acute stroke patients.

Objective To explore the expression profiles of circulating microRNA(miRNA)and potential markers for the diagnosis of adult fulminant myocarditis(FM). Methods The expression profiles of circulating miRNA were determined by microarray analysis and verified by real-time quantitative PCR.The key role of circulating miRNA in FM was determined via KEGG pathway enrichment.The correlations between miRNA and cardiac function parameters in patients with FM were analyzed.The receiver operating characteristic(ROC)curve was established to evaluate the sensitivity and specificity of circulating miRNA in the diagnosis of FM. Results Compared with healthy controls,the FM patients had up-regulated expression levels of miR-29b(t=18.925,P<0.001)and miR-125b(t=5.981,P=0.029)in the plasma.After treatment,the expression levels of miR-29b(t=12.943,P<0.001)and miR-125b(t=14.016,P<0.001)were significantly down-regulated.KEGG pathway enrichment showed that the targets of miR-29b were involved in inflammatory response and apoptosis pathways.The results of cell proliferation and apoptosis assay demonstrated the transfection of miR-29b mimic had a more significant inducing effect on cardiomyocyte apoptosis than that of miR-125b mimic(χ ²=6.168,P=0.047),whereas there was no significant difference in the inhibition of cell proliferation between the two groups(χ²=1.452,P=0.417).The expression levels of miR-29b and miR-125b were negatively correlated with left ventricular ejection fraction(r=-0.67,P=0.071;r=-0.49,P=0.003).They were positively correlated with cardiac troponin I level(r=0.61,P=0.019;r=0.52,P=0.016),interferon β level(r=0.42,P=0.014;r=0.36,P=0.021),and myocardial edema area(r=0.86,P=0.005;r=0.73,P=0.013).The ROC curve analysis demonstrated that miR-29b had higher sensitivity for the diagnosis of FM(93.6% vs.89.2%;t=0.896,P=0.795)and specificity(72.4% vs.59.6%;t=9.478,P=0.002)than miR-125b. Conclusion The circulating miR-29b may be a potential biomarker for the diagnosis of FM.

Objective To investigate the relationship between a novel polymorphism of C5L2 gene and type 2 diabetes mellitus (T2DM) in Uygur population from Xinjiang region.Methods A novel single nucleotide polymorphism(SNP),698C＞T(P233L) was found using a polymerase chain reaction direct-sequencing method.C5L2 gene 698C ＞ T variant from 252 patients with T2DM and 747 healthy control subjects was detected by polymerase chain reaction and restriction fragment length polymorphism.Result Heterozygote carriers of the 698CT genotype were more frequent among T2DM patients than that among controls (0.107 vs 0.036,x2 =18.576,P＜0.01) in the Uygur population. After adjustment of confounding factors such as sex,age,smoking,alcohol consumption,and hypertension,as well as serum levels of triglyceride,total cholesterol,low-density lipoproteincholesterol,and high-density lipoprotein-cholesterol,the difference remained significant ( P＜0.01,OR =3.373,95％ CI 1.736-6.553 ).Conclusion The CT genotype of the C5L2 gene might be a risk factor of T2DM in Uygur nationality population in Xinjiang.

Objecflve To determine the prevalences of nutritional risk,undemutrition,overweight,and obesity as well as nutritional support and the changes of nutritional risks from admission to discharge or over a two-week period.Methods A consecutive sampling was performed.Dam were collected from general surgical depart-ments in three Beijing teaching hospitals from March to July in 2007.Patients were screened using Nutritional Risk Screening 2002(NRS2002)on admission and two weeks after admission(or discharge).The nutritional supper apphcation during hospital stay was recorded.NRS2002 score≥3 was classified as nutritional risk.BMI<1 8.5kg/m2 with impaired genend condition was defined as undemutrition.Results Among 300 enrolled patients,the NRS2002 WaS completed by 99.0%(297/300)of all patients.The nutritional risk and the prevalence of under_nutrition,overweight,and obesity was 30.0%,8.1%,38.3%,and 9.4%,respectively at admission.Fifty of 90(62.2%)patients who were at nutritional risk received nutritional support while 40 of 210(19.O%)non-risk patients received nutritional support.Especially among major abdominal surgery patients,56 of 90(71.6%)pa-tients who were at nutritional risk received nutritional supper while 35 of 81(43.2%)non-risk pafients received nutritional support.The prevalence of nutritional risk changed from 30.0%to 35.8%(X2=2.271,P=0.132).Conclusions NRS2002 is a feasible nutritional risk screening tool among general surgical pafienm in selected Bei-jing teaching hospitals.Nutritional support is somehow inappropriately apphed in general surgical hospitalized pa-tients.The prevalence of nutritional risk remains unchanged in general surgical patients during hospitalization.

Objective To evaluate the efficacy and safety of long-term nucleos (t) ide analogue treatment in patients with chronic hepatitis B (CHB).Methods Two hundred and two initially treated patients with CHB admitted in Zhejiang Provincial People's Hospital during March 2013 and August 2016 were enrolled in the study.Patients were divided into six groups according to the different antiviral therapy:adefovir group (ADV,n =43),entecavir group (ETV,n =44),lamivudine group (LAM,n =25),telbivudine group (LDT,n =23),LDT + ADV group (n =22),and LAM + ADV group (n =45).HBV DNA negative conversion rate,HBeAg serological conversion rate and estimated glomerular filtration rate (eGFR) at baseline and at 48th,96th,144th wk of treatment were measured.Chi-square test and repeated measure of ANOVA were used to analyze the data.Multivariate Logistic regression analysis was applied to detect the relevant risk factors of renal dysfunction in CHB patients.Results After treatment for 144 wks,the HBV DNA negative conversion rates in ETV and LDT group were higher than that in ADV group (both P ＜ 0.01),the levels of eGFR in ADV,ETV,LAM and LAM + ADV group were declined with time,while the eGFR levels in LDT and LDT + ADV group were increased with time (Ftime =3.939,Fgroup =3.983,P ＜0.01 or ＜0.05).After treatment for 96 wks and 144 wks,the levels of eGFR were higher in LDT and LDT + ADV group than those in other groups,respectively (all P ＜ 0.05).Multivariate Logistic regression analysis showed that age ≥40 (x2 =16.145,OR =4.452,95 ％ CI 2.149-9.223,P ＜ 0.05),mild abnormality of eGFR at baseline (x2 =16.449,OR =4.336,95％ CI 2.144-8.891,P ＜ 0.05),and ADV treatment (x2 =5.837,OR =5.280,95％ CI 1.369-20.365,P ＜ 0.05) were independent risk factors of renal dysfunction in CHB patients.Conclusion LDT long-term monotherapy or combination with ADV may improve renal function for patients with CHB,which provides a reference for long-term treatment of CHB patients with nucleos(t) ide analogues.
