Cytokine-induced killer cells (CIK cells) are a group of CD3+ CD56+ T cell-based heterogeneous cells generated in vitro,with T-cell receptor (TCR) specificity of CD8+ T cells and anti-tumor activity of non-restrictive major histocompatibility complex (MHC).Recent studies indicated that vaccination with CIK cells induced strong anti-tumor activity in the treatment of malignant lymphoma.These researches show that CIK cell-based immunotherapy has the important values for patients with malignant lymphoma.

BACKGROUND:The major aim of repair of lumbar spondylolisthesis is to restore and reconstruct the stability of spine sequence, and to relieve compression of herniated disc on nerve root. Pedicle screw system and bone graft fusion become the preferred way to treat spondylolisthesis of most scholars. Most scholars are prone to posterior interbody fusion or posterolateral interbody fusion.
OBJECTIVE:To compare the clinical curative effects of posterior autologous iliac bone graft fusion and posterior Cage intervertebral bone graft fusion in patients with degenerative lumbar spondylolisthesis by observing fusion rate and height of intervertebral loss.
METHODS:A total of 61 patients with degenerative lumbar spondylolisthesis in Xuancheng Central Hospital from July 2008 to December 2013 were enrol ed in this study. According to the different types of interbody fusion, 37 cases in autologous ilium group received posterior autologous iliac bone graft fusion. 24 cases in the Cage interbody fusion cage group underwent posterior Cage interbody fusion cage fusion. Operation time, blood loss, spondylolisthesis reduction, graft fusion and Japanese Orthopaedic Association score were compared between 
the two groups. The significance of different fusion manners on prognosis was explored in patients with degenerative lumbar spondylolisthesis.
RESULTS AND CONCLUSION:No significant difference in blood loss was detected between the two groups (P>0.05). However, the operation time was significantly longer in the autologous ilium group than in the Cage interbody fusion cage group (P<0.05). The reduction rate, bone graft fusion rate and improvement rate of clinical curative effects were good in both groups, and no significant difference was detectable in above indexes between the two groups (P>0.05). Significant difference in the height of intervertebral loss was detectable between the two groups in final fol ow-up (P<0.05). The height of intervertebral loss was better in the Cage interbody fusion cage group than in the autologous ilium group. These findings indicate that two kinds of bone graft fusion manners for lumbar spondylolisthesis obtained good reduction and clinical curative effects, but the height of intervertebral loss was smal in the Cage interbody fusion cage fusion during long-period fol ow-up, and the clinical effect was good.

Objective To investigate the clinical characteristics of Kennedy disease with secondary mitochondrial dysfunction and glutaric aciduria typeⅡ.Methods The clinical data of 1 case Kennedy disease with secondary mitochondrial dysfunction and glutaric aciduria typeⅡwas retrospectively analyzed.Results The patient presented muscle weakness in proximal limbs, fasciculation, bulbar palsy, amyotrophy, postural tremor, sensory disturbance, gynaecomastia, impotency.The level of serum creatine kinase and urinary glutaric acid were elevated. Electromyogram and nerve and muscle biopsy supported mixed damage in peripheral nerves, as well as neurogenic and secondary myogenic pathologic changes in muscles.Gene sequencing indicated trinucleotide CAG repeated amplification for 47 times in chromosome X.Diabetes was diagnosed at 7 years after onset.Conclusions The pathogenesis of Kennedy disease is very complex, which may involve myogenic factor.The treatment to the secondary mitochondrial and lipid metabolic disturbance in muscle can improve the muscle weakness to a certain extent.

Objective The abnormal proliferation of renal cells underlies the pathology of progressive glomerulosclerosis.Cell proliferation is regulated by cell regulatory proteins.This study aims to investigate the expression of cyclin-dependent kinase inhibitor P16INK4a in renal tissue of patients with primary mesangial proliferative glomemlonephritis(MsPGN)and its clinical significance.Methods Paraffinembedded renal biopsy renal tissue sections from 36 patients with MsPGN were detected by immunohistochemical staining.Normal renal ti8.Sue sections from 6 nephrectomized patients with trauma were used as controls.Possible correlation between p16 positive area and sclerotic and crescentic glomeruli,blood pressure,serum creatinine,endogenous creatinine clearance rate,and total proteinuria were evaluated.Resuits There were very few expression of P16INK4a in normal glomemli and renal tubular-interstitial.Compared to the normal comrol group,the expression of P16INK4a in 36 renal biopsy specimens with MsPG'N was significantly higher(P<0.01),especially in sclerotic and crescentic glomeruli,and it had wild expression of the same components in no sclerotic and crescentic glomeruli.There was a statistic difference(P<0.01).No statistic difference was found between the expression of P16 INK4a in renal tubular-interstitial of two groups(P>0.05).Therewag positive correlation among P16 INK4a of glomeruli without use of glucocorticoid/immunoinlfibitors and ACEI/ARB(r=0.774,0.497,P<0.01),also blood pressure and 8ul～m creatinine(r=0.64,0.473,P<0.01).It was negstively correlated with endogenous creatinine clearance rate and total proteinuria(r=-0.487,-0.694,P<0.01).There is no correlation between P16INK4s and clinical data in renal tubular-interstitial.Conclusion This study demonstrated that overexpression of P16INK4a in renal tissue with MsPGN may promote the regression ofabnormal proliferation and senescence cells,and induce sclerotic and crescentic glomeruli.The expression level of P16 INK4a not only reflected the degree of renal function,but also hypertension and proteinuria.In brief,expression of P16INK4a may be an important marker in renal sclerotic or crescentic glomeruli of MsPGN.Some drugs may prevent the expression of P16INKa.
