Objective To investigate the clinical value of serum lipoprotein ( a ) concentration in evaluation of plaques characteristics for patients with coronary atherosclerotic heart diseases ( CAHD ) . Methods Using case-control method, Patients with suspicious CAHD, received coronary computed tomography angiography in the Shanghai East Hospital during October 2013 to June 2015 were enrolled.According to the results of coronary artery CTA, the patients were divided into two groups : the CAHD group (352 cases) and control group(438 cases) , the particle concentrations and mass concentration of lipoprotein(a), triglyceride, total cholesterol, HDL-C, LDL-C, glucose, HBA1c and hs-CRP and other tests were measured, the patients of CAHD group were divided into three subgroups by characteristics of coronary artery plaques including soft plaque (176 cases), calcified plaque (90 cases) and mixed plaque (86 cases), analysis were made with all these data.Using T test or variance analysis to compare the means between or among groups, the risk for CAHD was analyzed by logistic regression, the relationship between LP (a) -P and LP( a) -M were explored by linearly egression analysis, Conformance test were analyzed using kappa test.Results Compared with control group, the mean results of the CAHD group are significantly higher than that of control group, including LP (a) -P 18.5(8.3 -43.0))nmol/L vs.13.6 (7.6-32.4)nmol/L( t =-2.110), LP(a)-M 183(71 -361)mg/L vs.126(67 -293)mg/L(t =-2.063), age (62 ±9)years vs.(52 ±9)years(t=-7.691), hs-CRP 0.86(0.44-1.97) )mg/L vs.0.70(0.38-1.64)mg/L(t=-2.236), glucose (6.1 ±2.29 )mmol/L vs.(5.36 ±1.32 )mmol/L(t=-4.914), BA1c (6.13 ±0.98) % vs.(5.81 ±0.58) %(t=-4.842), APO(B) (1.09 ±0.33) g/L vs.(1.03 ±0.29) g/L( t=-2.407), all of the P values <0.05;The relative risk(RR)of age, glucose, LP( a)-P and LP ( a)-M are 1.067, 2.377, 1.384 and 1.342 respectively; Among the three types of plaques groups,the mean differences of age, TC, HDL-C, LDL-C and LP ( a)-P are statistically significant ( F=6.276,3.060,3.127,4.723,2.878;all of the P<0.05);The median of LP ( a)-P in the soft plaque group 20.3(8.3-48.2)nmol/L is higher than that of the mixed plaque group 15.7(7.3-26.0)nmol/L(P<0.05 ) and calcified plaque group 15.6 ( 8.1 -23.1 ) nmol/L ( P <0.05 ).The linearly regression equation of LP ( a) -M and LP( a)-P is Y=6.646X, r=0.939; Consistency test indicate the two methods are not consistent when used for grouping ( Kappa value is 0.557 ).Conclusions Serum concentration of lipoprotein(a) is an independent risk factor of CAHD, and the particle concentration of LP(a) is closely related to the characteristics of the plaques, especially to the soft plaque.

Aliphatic amines in infant food packaging materials were extracted and concentrated by 0 . 5 mL of acidified methanol using gas purge microsyringe extraction ( GP-MSE ) . Pre-column fluorescence labeling of amines was achieved in mild conditions with 10-ethyl-acridine-2-sulfonyl chloride ( EASC ) as labeling reagent. The derivatization was carried out at 60℃ and pH 10. The derivatives were successfully separated on a Hypersil GOLD column with excitation and emission wavelengths of 262 and 430 nm, respectively. The detection limits were in the range of 0. 4-0. 6 μg/kg, and the quantitation limits were in the range of 1. 2-2. 1 μg/kg. All analytes were in good linearity in the concentration range of 2. 0-2000 μg/L with correlation coefficients of higher than 0. 998. The developed method was characterized by celerity, accuracy and high sensitivity. It was successfully applied to the determination of aliphatic amines in infant food packaging materials.

Objective: To study the clinicopathological features, diagnostic features and differential diagnoses of SMARCB1 (INI1)-deficient sinonasal carcinoma (SDSC). Methods: Six cases of SDSC diagnosed at Eye, Ear, Nose and Throat Hospital, Fudan University from 2016 to 2018 were retrieved; the clinical features, histomorphology, immunophenotype, radiology and outcome were analyzed with review of literature. Results: There were five men and one woman with age range of 37 years to 75 years (mean 56 years). One case was in stage T2, and 5 cases were in stage T4. Computer tomography and magnetic resonance imaging showed a mass occupying the sinonasal cavity with bone destruction in all six patients. Microscopically, the tumors had infiltrative margins. Four tumors were composed mostly of basaloid cells, which possessed high nuclear/cytoplasmic ratio,scant cytoplasm,and minimalnuclear pleomorphism; and the cells were arranged in sheets or nests in a desmoplastic stroma. Two tumors were composed of rhabdoid cells, which possessed abundant, eosinophilic cytoplasm and eccentric nuclei, often growing in a nests or sheets pattern. Immunohistochemical staining showed that 6/6 cases had complete loss of INI1, diffusely and strongly positive for CKpan, and were negative for S-100 and EBER ISH; 4/6 cases were focally positive for p63; 1/5 was focally positive for Syn and p16. The Ki-67 index was 30% to 70%. The follow-up period ranged 1-26 months, with one patient died of extensive metastases, one had local recurrence, and two had lymph node metastases; one was alive without disease, and one was lost to follow-up. Conclusions SMARCB1 (INI1)-deficient sinonasal carcinoma is mostly aggressive, with rapid progression and poor prognosis. Histomorphological spectrum predominantly consists of basaloid type and rhabdoid type. The complete loss of nuclear expression of INI1 can help to distinguish this tumor from its many mimickers.
