1.Research progress of cytokine-induced killer cell-based immunotherapy for malignant lymphoma
Journal of Leukemia & Lymphoma 2014;23(12):760-764
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.
2.Clinical features of Kennedy disease with secondary mitochondrial dysfunction and glutaric aciduria typeⅡ(report of 1 case)
Journal of Clinical Neurology 2015;28(5):377-379
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.
3.Two kinds of posterior intervertebral fusion for lumbar spondylolisthesis:fusion rate and height of intervertebral loss
Chinese Journal of Tissue Engineering Research 2015;(35):5630-5635
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 observe the clinical effects of scalp acupuncture and body acupuncture on post-stroke ataxia. Methods: 124 cases of post-stroke ataxia were treated with scalp and body acupuncture to observe the changes of blood velocity in the blood vessels of the brain and the total effects after treatment. Results: The total effective rate was 93.5% based on the result of Berg Balance scale, and was 91.1% on the activities of daily living (ADL) index. The blood velocity of the vertebrobasilar artery was higher after the treatment compared to before treatment (P<0.05). Conclusion: Acupuncture had good clinical effects.

Objective: To analyse the effects of CVP chemotherapy through arterial injection (CVPC) in the treatment of squamous cell carcinoma (SCC) of maxillary sinus.Methods:39 cases of primary squamous cell carcinoma of maxillary sinus at stage Ⅳ (M0) were treated with following regimen : carboplatin 300~350 mg/m 2 ia gtt on d1, etopside 100 mg ia gtt on d1~5, pingyangmycine 8 mg ia gtt on d1~5. The drugs were given through superficial temporal artery at the level of internal maxillary artery. Gave one cycle treatment before operation which was practised 4 weeks later.Results:Partly remission was found in all patients after chemotherapy. Pathological margin of original focus was negative after operation. 5 cases lost follow up. 4 cases were dead of distant metastasis (after 5,7,8 and 12 months respectively). 30 cases were alive without tumour. 17 cases were over 5 years, 6 over 3 , 4 over 1 and 3 less than one year.Conclusion: CVP arterial injection chemotherapy is effective in the treatment of SCC of maxillary sinus at late stage.

Objective To investigate the application of computed radiography(CR) in X-ray projection of whole lower limbs.Methods The radiography in the patient with bilateral knee-malformation was performed using 500 mA X-ray apparatus and several imaging plates(IP) jointed together,then the images including whole both sides of lower limbs were obtained by post-proccesing technique.Results The images not only could show the whole lower limbs on a single film,but be intact.The images also could be used for measuring the length of leg,the angle between the axises of the thigh and the magnifying really.Conclusion The image of whole bilateral lower limbs with a good quality and unity can be acquired using CR and post-processing technique appropriately.

Chongqing Medicine 2017;46(5):635-637
Objective To make clear the relationship between the genetic polymorphism of MMP-1 and implant early failure.Methods We conducted a case control study,53 cases patients (no smoking history and without periodontitis) who have underwent dental implant were divided into experimental group(with dental implant failure) and control group(with dental implant success) according to early failure of dental implant (within one month).DNA of 53 patients in Han nationality were extracted by using Chelex-100 method and polymorphisms of the mmp-1-1607 gene were detected by restriction fragment length polymorphism after polymerase chain reactions.Results Patients with MMP-1-1607(1G/2G) genotype exhibited a significantly higher occurrence of implant early failure than those with MMP-1-1607(1G/1G) gene type(P<0.05).The OR of the 1G/2G versus the 1G/1G of the MMP-1-1607 genotype was 13.894(P<0.05).Conclusion MMP-1-1607(1G/2G) genotype is associated with implant early failure.

The cell volume, length, cross-section area, surface area, width and thickness of isolated cardiac myocytes were measured by using of a new computer system of coulter channelyzer and avias eye imaging analysis system. The rats, 3 weeks to 24 weeks in age after birth, were performed thoracic operation the morphological growth characteristics of isolated cardiac myocytes were observed.1. Physiological growth of normal cardiac myocytes was due to increase in cell volume, i. e. the cell length and cross-section area were enlarged. In the mean time, the changes in cross-section shape of myocytes happened when the myocytes growing.2. The major axis of cross-section area of myocytes was enlarged but the minor cross-section diameter did not show any more changes. So that, the growth lead to the cardiac myocytes be flattened in shape. The flattened growing pattern was one of the characteristics of normal growing myocytes. It might be very significant for the clinicians to eliminate the factors which would stimulate myocytes to be enlarged in cell width, and to treat and to prevent the heart disease.
