Interleukin-17A (IL-17A) is one of the proinflammatory cytokines produced by a subset of CD4+T cells named Th17 cells. It plays a crucial role in both host innate and adaptive immune responses against colonization and infection of respiratory tract bacteria. Studies in animal models have demonstrated that IL-17A can induce the expressions of various chemokines, inflammatory factors and adhesion molecules via multiple intracellular signaling pathways and recruit neutrophils to infection sites. Moreover, recent stud-ies have shown that single nucleotide polymorphisms (SNPs) of IL-17A coding gene can regulate the produc-tion of IL-17A in serum, resulting in individual difference in colonization rate by Streptococcus pneumoniae. This review presents recent data related to the structure, functions and signaling pathways of IL-17A, sum-marizes its roles in host defense based on studies in animal models and discusses the effects of genetic varia-tion of IL-17A on colonization, susceptibility, clinical characteristics and disease prognosis of human respira-tory tract bacteria.

Objective:To investigate the clinical features of ocular involvement and the application of Rose criteria in patients with relapsing polychondritis (RP).Methods:The data from RP patients with ocular involvement were collected and analyzed. Patients included must have at least one major criteria of Michet criteria and the application Rose criteria was also investigated. Demographic data of these patients was presented as percentages. The difference between types of disease onset was tested by Mann-Whitney U and comparison among groups was tested by False Discovery Rate. Results:A total of 192 patients were enrolled 98 males and 94 females. The mean age of disease onset was (42±14) (0.5-79) years old, the median disease duration (DD) was 13(0.5, 600) months. The median RP disease activity index (RPDAI) was 39(9-74) and the median RP organ damage index (RPODI) was 2.5(0.1, 108). The median RP damage index (RPDAM) was 3(1-6). The statistical significant difference was identified in median DD between groups of nose and pinna ( Z=10.775, P<0.01), nose and OEH ( Z=9.277, P<0.01), in RPODI between groups of nose and pinna ( Z=7.999, P=0.031), nose and and extra-cranial organs ( Z=8.115, P=0.030) and eye and airway involvement of RPDAM could be seen between groups ( Z=7.683, P=0.037) respectively. Ocular involvement(50.0%), auricular chondritis(21.4%) and airway chondritis(13.5%) were the top three most common symptoms at disease onset. The ocular involvement(100%), airway chondritis (75.0%) and inner ear involvement(69.3%) were the top three most frequent affected organs. All parts of eye could be involved in RP ocular damage. Single-organ involvement was 59.9%; and multi-organ involvement could be seen in 40.1% patients. Diagnostic strength was enhanced by application of Rose criteria in 171 cases fulfilled Michet criteria and 21(10.9%) cases partially fulfilled Michet criteria fulfilled Rose criteria. Active screening for organ (especially inner ear and airway) involvement would improve the rate of early diagnosis. The pinna and airway involvement suggested nose and middle-ear might be involved. Conclusion:Ocular involvement in RP can involve all parts of the eye ball. Examining the inner ear and airway may help to confirm the diagnosis. It is worthy to apply this to clinical practice.

OBJECTIVE:
To explore the feasibility of detecting of Y-STR of fetal DNA in maternal plasma using Ion Torrent PGM™ System.
METHODS:
A total of 16 fetal DNA samples from maternal plasmas (8 cases from 38 weeks gestational age and 8 ones from 12 weeks) were prepared and a multiplex assay with 7 STR loci (DYS390, DYS391, DYS393, DYS438, DYS437, DYS456, DYS635) was designed for multiplex-PCR amplification. Using Ion Torrent PGM™ System, the results of Y-STR sequences and capillary electrophoresis were obtained and compared.
RESULTS:
Y-STR specific alleles were detected in the maternal plasma of all the pregnant women having male babies of second and third trimester, which were higher than that detected by capillary electrophoresis. Consistent Y-STR genotypes were observed between fetal DNA from maternal plasma and genomic DNA from the newborn babies.
CONCLUSION
Based on Ion Torrent PGM™ System, the prenatal Y-STR detection method may provide a high-sensitive and high-throughput choice for prenatal STR detection in forensic testing.

BACKGROUND:Transplantation of autologous stem cells for treatment of liver cirrhosis has been widely reported.But up to now,there exist some concerns for clinical physicians,including relationship between stem cells and post-transplantation prognosis/turnover of liver cirrhosis,directed differentiation of stem cells in the impaired liver,and malignant phenotype.OBJECTIVE:To dynamically monitor the serum levels of alpha-fetoprotein(AFP)and AFP variants(AFP-L3)in decompensated cirrhosis patients following intrahepatic transplantation of peripheral blood stem calls via portal vein and evaluate the safety of this treatment method.METHODS:A total of 44 decompensated cirrhosis patients who underwent intrahepatic transplantation of peripheral blood stem cells via portal vein in the 309 Hospital of Chinese PLA in April 2007 were included in this study.Prior to and after surgery,serum levels of AFP and AFP-L3 were detected by chemiluminescence.Through the use of a positive criterion for liver cirrhosis,i.e.,the proportion of AFP-L3 in AFP[AFP-L3(%)]≥10%,and the relationship between decompensated cirrhosis treatment using stem cells transplantation and the malignant phenotype of liver cancer were analyzed.RESULTS AND CONCLUSION:At 2 months after surgery,serum level of AFP showed a transient increase.There was no significant difference in AFP-L3(%)between prior to and after surgery(P>0.05).No significant difference in AFP-L3-positve rate,as well as AFP-L3(%),existed among patients with different serum level of AFP.These findings indicate that clinical symptoms and liver function of decompensated cirrhosis patients recovered to some extent after transplantation of peripheral blood stem cells via portal vein.Results regarding serum level of AFP-L3,a serological marker of liver cancer,did not demonstrate the appearance of malignant biological phenotype.
