OBJECTIVETo study clinical effects of unilateral pedicle screw-rod system fixation combined with the single the cage of interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor.
METHODSFrom February 2010 to December 2011, 39 patients with lumbar degenerative instability after invalid conservative treatment were treated with unilateral fixation combined with interbody fusion via the paraspinal intermuscular approach under MAST Quadrant retractor. The indexes such as the operative time, blood loss, complications, VAS pain scores, JOA (subjective symptoms of low back pain,lower limb pain and numbness, sensory disturbance, movement disorders) scores, modified Macnab criteria for curative effect evaluation were observed before treatment, at the 1st month after treatment and the latest follow-up. The intervertebral fusion was studied on the X-ray at the latest follow-up.
RESULTSAll the patients were followed up, and the mean during was (22.3 +/- 8.6) months. The operation time was (138 +/- 46) min, and the amount of bleeding was (335 +/- 152) ml. There were no complications such as cerebrospinal fluid leakage and spinal nerve injury during operation, and no incision infection after operation. The VAS pain score was reduced from preoperative 7.93 +/- 1.27 to 2.05 +/- 1.18 on the 1st month after operation and 1.89 +/- 0.42 at the latest follow-up. The JOA total score was improved from preoperative 1.59 +/- 0.42 to 8.86 +/- 0.37 on the 1st month and 9.02 +/- 0.29 at the latest follow-up. According to modified Macnab criteria, there were 17 cases got an excellent result, 19 good, 3 case fair. Thirty-five patients got intervertebral bony fusion at the latest follow-up.
CONCLUSIONUnilateral pedicle screw-rod system fixation combined with single cage interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor is a safe, minimally invasive, satisfactorily effective methods to treat lumbar degenerative instability.

Objective To discuss the role of EB virus (EBV)in the pathogenesis of systemic lupus erythematosus(SLE) in children through investigating the copies of EBV DNA and expression of EBV genes in peripheral blood mononuclear cells(PBMCs).Methods (1)PBMCs were isolated from 30 patients with SLE and 12 healthy normal controls respectively and DNA was extracted from PBMCs.(2) PBMCs were co-cultured with EBV for 12 days and RNA was extracted from PBMCs.(3)Real-time fluorescence quantitative PCR(Real-time PCR) was applied to detect the copies of EBV DNA in PBMCs.(4)Reverse transcription PCR was applied to detect expression of EBV genes.Results (1) Compared with the healthy control group [(40.1 ± 11.6) copies/μg],a significant increase of EBV DNA copies was observed in SLE group[(658.6 ± 183.6) copies/μg] (P <0.05).The EBV DNA copies in the active SLE group [(785.2 ± 179.2) copies/μg] were significantly higher than those in the non-active SLE group [(586.0 ± 193.1) copies/μg] (P < 0.05).(2)There was no correlation between EBV DNA copies and systemic lupus erythematosus disease activity index (r =0.03,P > 0.05).(3) After PBMCs got co-cultured with EBV,expression of latent EBV genes and lytic genes were both increased in the patients and healthy controls.The latent EBV genes including latent membrane protein 1 (LMP1),LMP2,EBV nuclear antigen 1 and the lytic genes including BCRF1,BLLF1 were all increased significantly in the patients compared with the healthy controls (all P < 0.05).Conclusions There is a significant increase of EBV DNA copies and aberrant expression of EBV genes in SLE patients,which suggests that EBV may contribute to the pathogenesis of SLE.

Objective To investigate the expression and significance of Epstein-Barr virus (EBV) genes in children with systemic lupus erythematosus (SLE).Methods Peripheral blood mononuclear cells (PBMCs) were isolated from 20 children with SLE and 12 healthy human controls.Enzyme-linked immunosorbent assay (ELISA) was conducted to detect anti-EBV viral capsid antigen (VCA) IgG/IgM antibodies.The culture supernatants of cells from patients with anti-EBV VCA IgG/IgM antibodies were collected,and PBMCs from the patients and controls were co-cultured with the supernatants respectively for 12 days.RNA was extracted from PBMCs before and after the coculture,and reverse transcription-PCR was performed to detect the expression of EBV genes,including LMP1,LMP2,EBNA1,BCRF1,BLLF1 and BILF1 genes.Results LMP1 gene was detected in fresh PBMCs from 10 out of 20 patients and 1 out of 12 controls (P < 0.05).No significant differences were observed between the patients and controls in the detection rate of LMP2 gene (4/20 vs.1/12),EBNA1 gene (13/20 vs.3/12),BCRF1 gene (3/20 vs.1/12) or BLLF1 gene (5/20 vs.2/12) in fresh PBMCs.After co-culture with the supernatants of cells from patients with anti-EBV VCA IgG/IgM antibodies,the expressions of EBV genes in these PBMCs were increased to different degrees,and there was a significant difference in the expressions of EBV latent genes LMP1,LMP2 and EBNA-1 as well as EBV replicative genes BCRF1 and BLLF1 between the patient-derived and control-derived PBMCs (all P < 0.05).Conclusions There is an aberrant expression of EBV genes in children with SLE,and EBV genes may contribute to the development of SLE.

Objective To investigate the impact of CD4+ CD25+ FOXP3+ regulatory T(Treg) cells on tumor recurrence in liver transplantation for hepatocellular carcinoma (HCC). Methods Im-munohistochemistry and flow cytometry were used for analysis of the frequency of Treg. Meanwhile,it was compared with that of non-cancer liver transplantation patients. Results The frequency of CD4+CD25+ FOXP3+ regulatory T cells in the blood of HCC liver transplantation was (10. 15 ±1. 00) % , which was significantly higher than that in the normal control group (3. 20±1. 18) %. Cir-culating CD4+ CD25+ FOXP3+ Treg frequency was increased significantly and correlated with the tumor recurrence in the HCC patients. An abundant accumulation of Treg concurrent with significant-ly reduced infiltration of CD8+T cells was found in tumor regions. Conclusion Increased CD4+ D25+FoxP3+ Treg may impair the effectors function of CD8+ T cells, promote the tumor recurrence and re-present a therapeutic target for HCC liver transplantation.

The identity of higher-order neurons and circuits playing an associative role to control renal function is notwell understood.We identified specific neural populations of rostral elements of brain regions that project multisynaptically to the kidneys in 3~ days after injecting a retrograde tracer pseudorabies virus (PRV)-614 into kidney of 13 adult male C57BL/6J strain mice.PRV-614 infected neurons were detected in a number of mesencephalic (e.g.central amygdala nucleus),telencephalic regions and motor cortex.These divisions included the preoptic area (POA),dorsomedial hypothalamus (DMH),lateral hypothalamus,arcuate nucleus (Arc),suprachiasmatic nucleus (SCN),periventricular hypothalamus (PeH),and rostral and caudal subdivision of the paraventricular nucleus of the hypothalamus (PVN).PRV-614/Tyrosine hydroxylase (TH) double-labeled cells were found within DMH,Arc,SCN,PeH,PVN,the anterodorsal and medial POA.A subset of neurons in PVN that participated in regulating sympathetic outflow to kidney was catecholaminergic or serotonergic.PRV-614 infected neurons within the PVN also contained arginine vasopressin or oxytocin.These data demonstrate the rostral elements of brain innervate the kidney by the neuroanatomical circuitry.
