Suspension array technology,a bead-based multiplex assay,allows a fast and automatic detection of multi-analytes and batch samples in limited sample volume,and it is great potential clinical application in the determination of autoimmune antibodies,muhitumor markers,the phenotype of Human Leukocyte Antigen and the genes of infectious pathogens.However,currently,there are various limitations which hinder the clinical application of this technology broadly.The globally accepted panel of multi analytes,performance criteria,and quality control programs should be established before we get benefit from this high throughput,sensitivity and repeatability platform,which will help to provide scientific and accurate laboratory data for the clinical diagnosis,treatment and prevention.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.

OBJECTIVE: To investigate the audiologic characteristics of the children with cleft lip and/or palate. METHOD: Sixty-two children with cleft lip/palate were enrolled in the study. Tympanometry, DPOAE, ABR were tested in all the chidren. RESULT: Regarding the ABR threshold as the diagnostic criteria, 51 (41.13%) ears had hearing loss, mainly moderate. Sixty-three (59.43%) ears had abnormal tympanometry, which meant the disorder function of the middle ear. Twenty-six (56.52%) ears didn't pass the DPOAE. CONCLUSION The proportion of the hearingloss in the children with cleft lip/palate was large. There was a good coherence among the three objective examinations when assess the children with cleft lip/palate.

Objective To investigate the change and significance of follicular helper T cells (Tfh) percentage in the peripheral blood of the patients with rheumatoid arthritis (RA).Methods The RA patients treated in this hospital from September to November 2016 were selected and divided into the RA active group and RA stable group,35 cases in each group.Contemporaneous 35 individuals undergoing physical examination were selected as the healthy control group.The percentage of peripheral blood CD4+ CXCR5+ ICOS+ Tfh cells was detected by flow cytometry.The correlations between the percentage of peripheral blood Tfh cells in RA patients with the RA disease activity score 28 (DAS28),anti-CCP antibody and rheumatoid factor(RF) levels were analyzed.Results The percentage of peripheral blood Tfh cells in the RA active group was (0.84±0.16) ％,which was significantly higher than (0.64±0.15)％ in the RA stable group and (0.56±0.14)％ in the healthy control group,the difference was statistically significant (P＜0.01);moreover the percentage of peripheral blood Tfh cells in the RA stable group was also higher than that in the healthy control group (P＜0.05).The percentage of peripheral blood Tfh cells in RA patients had significantly positive correlation with DAS28 score and anti-CCP antibody level (r=0.355,0.324;P＜0.01),and had no correlation with the RF level (r=0.205,P＞0.05).Conclusion The percentage increase of peripheral blood Tfh cells in the patients with RA might be related with the pathogenesis and development of RA.
