OBJECTIVETo investigate the clinical effects of 360 degree circular decompression and transpedicle screw fixation to treat the ossification of thoracic posterior longitudinal ligament by posterior approach.

METHODSFrom December 2009 to November 2013, 18 patients with ossification of thoracic posterior longitudinal ligament ossification were treated with 360 degree circle decompression and transpedicle screw fixation by posterior approach. There were 8 males and 10 females,ranging in age from 32 to 67 years old, with an average of 51 years old. Four patients were accompanied with ligamentum flavum ossification. Longitudinal ossifications in 5 cases were located in the upper thoracic vertebra and 13 cases in the middle and lower thoracic vertebra. Five cases were typical type, 4 cases were segmental type, 6 cases were continuous type and 3 cases were mixed type. All the patients had the posterior spinal canal decompression combined with longitudinal ligament resection, interbody fusion with bone graft and internal fixation surgeries. The operation time,blood loss and complications were recorded. JOA score were applied to evaluate the neurological function recovery pre-surgery, 2 days post-surgery and the latest follow-up. The surgery effects were evaluated by Epstein-Schwall method.

RESULTSThe operation time ranged from 3 to 6 hours (mean, 4.2 hours). The blood loss ranged from 800 to 4 000 ml (mean, 1 800 ml). All the patients were followed up, and the duration ranged from 6 months to 3 years, with a mean of 1.8 years. The JOA score increased from preoperative 4.30 ± 2.60 to 7.60 ± 2.40 2 days after surgery, and 7.80 ± 1.90 at the latest follow-up (t = 4.61, P < 0.001). The JOA scores between 2 days after surgery and the latest follow-up had no significant differences (t = 0.28,P = 0.78). The neurological recovery rate was 74% 2 days after surgery and 71% at the latest follow-up. There were 4 cases got an excellent result,10 good,3 fair and 1 poor according to Epstein-Schwall evaluation method. Four patients had cerebrospinal fluid leakage, 3 patients had intercostal nerve paralysis or pain, and 1 patient had superficial incision infection. The neurological function in 3 patients became worse in the second day posteratively , and among them, 2 patients were recovered at the latest follow-up and 1 patient had no changes. All the patients got fusion of bone graft and no internal fixation loosening and fractures occurred.

CONCLUSION360 degree circular decompression and transpedicle screw fixation can resect different types of thoracic longitudinal ligament ossification, and can achieve a good clinical effect.

Objective To analysis the quality of life of patients with active ankylosing spondylitis (AS).Methods The quality of life was assessed in 52 patients with active AS using SF-36 and was compared with the general population.The correlation between the quality of life and the clinical measures of disease,in- cluding the Bath AS disease activity index(BASDAI),Bath AS functional index(BASFI),Bath AS metrology index(BASMI),patient's global assessment(PGA),spinal inflammation,total back pain,nocturnal back pain, and enthesis index(EI),were determined.Results The patients with active AS reported significant decreased scores on all dimensions of SF-36.The score of physical health components was poorer than that of mental health components.BASFI was the strongest factor correlated with the score of SF-36,followed by BASDAI and PGA.BASMI and total back pain were correlated with three dimensions only.In multivariate regression analysis,BASFI showed relative closer relationship to the qulity of life with active AS than other clinical mea- sures of disease and it accounted for 50.3%,35.2% and 47.9% of the variance in the physical health compo- nents,the mental health components and the overall score of SF-36,respectively.Conclusion The quality of life in patients with active AS is significantly declined compared with general population.The physical aspects seem to be more severely affected.Functional status of the patients with active AS are correlated with the quality of life closely.

The study aimed to investigate the effect of inhibition of poly(ADP-ribose) polymerase-1 (PARP-1) activity on tau phosphorylation in HEK293/tau441 cells and its mechanism. HEK293/tau441 cells were treated with 3-aminobenzamide (3-AB), a PARP-1 inhibitor, at different doses (0.5, 1, 2, 4 mmol/L). After 24 h, the cell morphology was observed under phase contrast microscope, tau phosphorylation level in different sites (tau-1, tau-5, Thr231) and the activity of glycogen synthase kinase 3 (GSK-3) were detected by Western blotting. The results showed: (1) 3-AB at different doses failed to change the morphology of cells; (2) The 3-AB-induced decrease in activity of PARP-1 resulted in increase of unphosphorylation level in tau-1(Ser195/198/199/202) sites; (3) The phosphorylation of tau was decreased in Thr231 site, while the total tau was slightly changed after 3-AB treatment; (4) With the increased phosphorylation of GSK-3 at Ser9 site, the activity of GSK-3 was decreased after 3-AB treatment. The results suggest that the inhibition of PARP-1 by 3-AB could decrease tau phosphorylation in HEK293/tau441 cells probably through decreasing GSK-3 activity.

Objective To investigate the role of CD4~+CD25~+ Treg cells on the pathogenesis of ankylos- ing spondylitis(AS), and to study the machanism of tumor necrosis factor(TNF)-?blocker on the treatment of AS by detecting the number of CD4~+D25~+ Treg cells before and after the treatment. Methods The diagno- sis of 10 AS patients was made based on the 1984 modified New York criteria. The patients received subcuta- neou injection of recombinant human tumor necrosis factor receptor-Fc fusion protein(rhTNFR-Fc)(etaner- cept)50 mg weekly for 8 weeks and 10 heathy subjects were enrolled for control. The mononuclear cells were isolated from peripheral blood in beth patients and controls. The number of CD4~+CD25~+ T cells and CD4~+ CD25~(high)T cells and the expression of CTLA-4. were detected by flow cytometry. Results The proportion of CD4~+CD25~+ T cells(24?19)% in total CD4~+ T lymphocytes of peripheral blood and CD4~+CD25~(high)T/CD4~+ T (6?6)% from AS patients before treated with rhTNFR-Fc was higher than that in healthy volunteers and AS patients after treatment(P

OBJECTIVETo investigate the efficacy and safety of secreted interferon in treatment of chronic hepatitis B.

METHODSA multi-center randomized open-label controlled clinical trial was carried out. The patients of the study group were treated by secretory human interferon alpha-2a, and the patients of the control group were treated with an ordinary interferon.

RESULTSALT normalization rate in the secreted interferon group was 48.3% and it was higher at the end of treatment than that of the control group, but there was no difference between the two groups at the end of the follow-up. HBV DNA dropped more in the study drug group, but there was no difference in the normalization rate between the two groups. HBeAg seroconversions in secreted interferon group and in the control interferon group were 19.0% and 18.4% respectively. The safety of the two types of interferon was satisfactory.

CONCLUSIONSSecreted interferon was superior to ordinary interferon in ALT normalization and HBV DNA drop at the end of treatment in chronic hepatitis B patients, but there was no difference at the end of the follow-up. There was also no difference in HBeAg negative and HBeAg seroconversion between the two groups.
