BACKGROUND:Numerous studies have demonstrated various therapeutic methods for cerebrospinal fluid leakage after spinal column surgery, including intraoperative and postoperative measures. Few studies addressed the therapeutic methods of cerebrospinal fluid leakage after cervical vertebra surgery using lumbar subarachnoid catheter drainage.
OBJECTIVE:To evaluate the therapeutic efficacy of sustainable drainage and lumbar subarachnoid catheter drainage for cervical postoperative cerebrospinal fluid leakage.
METHODS:923 patients underwent cervical spine surgery in the Department of Spinal Surgery, the First Affiliated Hospital of Xinjiang Medical University, China from June 2009 to October 2012. There were 24 cases of postoperative cerebrospinal fluid leakage with an incidence of cerebrospinal fluid leakage of 2.6%(24/923). The dural laceration that could not be repaired or be found induced cerebrospinal fluid leakage. Of them, 12 cases received lumbar subarachnoid catheter drainage (catheter group), and 12 cases received sustainable drainage (drainage group).
RESULTS AND CONCLUSION:Compared with the drainage group, the duration of cerebrospinal fluid leakage was significantly shorter in the catheter group (P<0.05). In the catheter group, one case affected cerebrospinal fluid infection. In the drainage group, two cases experienced cerebrospinal fluid cyst and one case suffered from cerebrospinal fluid infection. They were cured by symptomatic treatment. A total of 24 cases were fol owed up for 9-12 months. None of them affected cerebrospinal fluid leakage, cerebrospinal fluid infection or cerebrospinal fluid cyst. Results demonstrated that lumbar subarachnoid catheter drainage in the treatment of cervical postoperative cerebrospinal fluid leakage has a good effect.

BACKGROUND:Previous studies have shown that different doses of ionizing radiation may have some impact on maturation and immune function of dendritic cells. OBJECTIVE:To evaluate the effect of 18 F-FDG with different concentrations on maturation and immune function of dendritic cells from human peripheral blood mononuclear cells in vitro. METHODS:Human peripheral blood mononuclear cells-derived mature dendritic cells were divided into five groups:PBS, 92.5×10 4, 185×104, 370×104, 740×104 Bq/mL 18 F-FDG were separately added into each group. Dendritic cells were col ected 24 hours later. Apoptosis rate, phenotypic expression (CD1α, CD80, CD83, CD86, HLA-DR), ability of mixed lymphocyte reaction and expression of macrophage inflammatory protein 1αand monocyte chemotactic factor-1 in cellculture supernatant were detected. RESULTS AND CONCLUSION:Apoptosis rate, phenotypic expression of CD86, ability of mixed lymphocyte reaction and expression of monocyte chemotactic factor-1 were down-regulated after culture in 740×10 4 Bq/mL 18F-FDG. However, 18F-FDG at other concentrations had no influence on maturation and immune function of dendritic cells. This study demonstrates that low-concentration 18F-FDG has little influence on apoptosis, maturation, antigen presentation, and migratory capacity of dendritic cells, and it may be selected at an appropriate concentration as a label for dendritic cells in vitro.

OBJECTIVETo determine whether the matrix metalloproteinase 9 gene (MMP9) polymorphism is associated with the onset or progression of adolescent idiopathic scoliosis (AIS) in Chinese Han female.

METHODSThree single nucleotide polymorphisms (SNPs) (rs17576, rs2250889, rs1805088) were genotyped through TaqMan-based real-time PCR assay in 190 AIS patients and 190 controls, all of whom were females from Chinese Han population with matched age. Analyses performed included Hardy Weinberg equilibrium test, Pearson chi-square test, Logistic regression analysis, linkage disequilibrium analysis and haplotype analysis. The mean maximum Cobb angles with different genotypes in case-only dataset were also compared.

RESULTSAll 3 SNPs have reached Hardy-Weinberg equilibrium in the controls. Genotype and allele frequencies of all SNPs were found similar between cases and controls by Pearson chi-square test and Logistic regression. Genotype-phenotype analysis showed that patients with CC genotype in rs2250889 featured larger maximum Cobb angles.

CONCLUSIONMMP9 may not be a predisposition gene of AIS in Han female. However, homozygous mutation in rs2250889 can render scoliosis more severe, implying that MMP9 defect may result in deterioration of AIS.

Virus-like particles (VLPs) are composed of multiple copies of one or more expressed recombinant viral structural proteins which spontaneously assemble into particles upon expression. VLPs are non infectious because they assemble without incorporating genetic material. VLPs have structural characteristics and antigenicity similar to the parental virus because they mimick the wild-type virus structure. Hence, they are recognized readily by the immune system which induces strong anti-viral immune responses to stop virus infection. VLPs have therefore shown dramatic effectiveness as candidate vaccines and diagnostic reagent for virus. Here, in order to provide reference to the research of influenza VLPs, we reviewed the current research progress of influenza VLPs, and discussed the characteristics associated with producing VLPs for influenza virus.
