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.

At present,pharmacy experiment is mainly in accordance with the traditional teaching mode,and students mechanically complete the experiments according to the demonstration of teachers.There is lack of interaction between teachers and students,and students lack independent thinking and experimental content innovation,which lead to the inefficient teaching effects.By flipping the classroom in the pharmacy experimental teaching,teachers prepare teaching courseware,teaching video and learning tasks before class,in class emphasize the experiment key and the difficult point,and carry on the preliminary experiment,and after class,summarize and analyze the practical problems that students have in the experiment,which have effectively aroused students' professional interest in learning and promoted their practical operation and independent thinking ability,and achieved good teaching results.

Objective To observe and compare the accurate dynamic changes of types Ⅰ, Ⅲ, Ⅴ, and Ⅵ collagens in the wound healing processes of the rabbit cornea undergoing laser epithelial keratomileusis (LASEK) or photorefractive keratectomy (PRK) and to investigate the possible mechanisms of corneal haze and myopic regression. Methods New Zealand White rabbits were divided into 8 groups: normal control group (n=6), 1, 7 d, and 1, 3, 4, 5, and 6 month groups (n=14). Every rabbit underwent LASEK in one eye while the other one with PRK. We used Western blot analysis to compare the wound healing process of dynamic changes of types Ⅰ, Ⅲ, Ⅴ, and Ⅵ collagens in the rabbit cornea at every time point. The results were analyzed with data analysis software. Results Western blot analysis showed that after LASEK, the cornea wound healing with types Ⅰand Ⅲ collagens were much faster than that of PRK, and the wound response was also much weaker. Whereas for types Ⅴ and Ⅵ collagens, their dynamic changes were similar between LASEK and PRK, and they both reached the peak value at 3 month after the surgery, but LASEK group returned to normal earlier than PRK group. The value of these two types of collagens after PRK was higher than that by LASEK. The changes of these four types of collagens may offer us at least partial explanation to the difference of formation of corneal haze and refractive regression. Conclusion There are significant differences between LASEK and PRK in types Ⅰ, Ⅲ, Ⅴ, and Ⅵ collagens or the time of reacting, reaching apex, and returning to normal. LASEK has slighter intensity of reaction. The results indicate that there is excessive aggradation of collagens after PRK, which may be the histological foundation of obvious haze and myopia regression.
