BACKGROUND:Lumbar spinal stenosis can severely affect the activities and functions of the lower limbs, and even cause paralysis. OBJECTIVE:To evaluate the clinical effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis. METHODS:The lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation were fol owed-up. The effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis was evaluated through assessing the clinical symptoms and improvement of signs, recovery of neurological function, as wel as intervertebral bone graft and fusion and the occurrence of complications. The effects of posterior decompression and intervertebral bone graft with internal fixation and simple decompression for the treatment of lumbar spinal stenosis were compared, in order to further determine the treatment of intervertebral bone graft with internal fixation. RESUTLS AND CONCLUSION:The fol ow-up results of the lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation showed that the symptoms of low back pain, partial limb sensory disturbances and intermittent claudication were improved significantly;the neurological recovery score could be up to 90%or above. Radiographic examination showed good intervertebral bone graft and fusion with less complication of nerves, blood vessels and dural injury. Comparative study showed that the excel ent and good rate of posterior decompression and intervertebral bone graft with internal fixation can reach to 95.2%, while the excel ent and good rate of simple decompression was 23.8%, indicating that the effect of posterior decompression and intervertebral bone graft with internal fixation was significantly better than that of simple decompression.

Objective To study the influence of arachidonic acid (AA) on L-type calcium channel in rabbits sin-gle cardiomyocyte and its mechanism of antiarrhythmia. Method The single ventricular cardiomyocyte was isolat-ed by using enzyme dispersion method and whole-cell clamp-patch technique was used to record L-type calcium current.All data were analyzed using ANOVA. Results AA inhibited Ica-L in a concentration-dependent manner. The application of 3 μmol/L, 10 μmol/L and 20 μmol/L arachidonic acid reduced the density of peak Ica-L from (10.79±0.93)pA/pF to (8.99±0.43)pA/pF to (7.60±0.35)pA/pF and to (5.60±0.30)pA/pF, respctive-ly (n=7, P<0. O1 ). The Ica-Lpartially resumed after washout. The AA up-shifted the I-V curves of Ica-L without changes of their shape,peak and reverse potentials. The AA also markedly shifted the inactivation curve to left, and prolonged the recorvery time from inactivation,but did not change the curve of calcium channel activation. Con-clustions By acceleration of L-type calcium channel inactivation and prolongation of recorvery time from inactiva-fion,arachidonic acid can reduce the calcium ion influe and prolong effective refractory period, playing the role of antiarrhythmia.

Objective To observe the change of regulatory T cells expression in severely burned rats gut ,To investigate the effects of regulatory T cells on CD3+CD4+ /CD3+CD8+lymphocytes and its relation with gut-origin endotoxin translocation .Meth-ods Fifty SD male rats were randomly divided into normal control group(n=10)and burn model groups(n=40) .Rats were burned to achieve Ⅲ degree scalding ,and a 30% total body surface area(TBSA) burn model was made .Rats were sacrificed before(normal control group) and after 0 .5 ,1 ,2 ,4 burn hour(PBH groups) .Flow cytometry techniques were used for the detection of the expres-sions of regulatory T cells and CD3+CD4+ /CD3+CD8+ lymphocyte in intestinal lymph nodes which were separated .The dynamic turbidity method was used for detection of endotoxin levels in portal vein blood .Results The expression of regulatory T cells was negativelycorrelatedwithCD3+CD4+ /CD3+CD8+ lymphocyteratio(r= -0.827,P<0.01)inintestinallymphnodeofrats,while the regulatory T cells was positively correlated with ET levels in portal vein blood plasma .(r=0 .782 ,P<0 .01) .Conclusion The expression of the regulatory T cells in intestinal lymph node in severely burned rats was increased compared to that in normal con-trol group .Regulatory T cells suppressed the expression of intestinal T lymphocytes ,leading to gut immune inhibition .The translo-cation of intestinal endotoxin has a close relationship with regulatory T cells in severely burned rats .Regulatory T cells could have portal effects on intestinal immunity barrier .

Objective To explore the diagnosis and treatment of hypopara thyroidism-deafness-renal dysplasia(HDR) syndrome in children.Methods According to the symptoms,signs,laboratory examination and the previous published papers of other authors,the disease of the child was diagnosed and treated,and some related literatures were reviewed.Results The 12-years-old boy presented with tetany and deafness and Chvostek's and Trousseau's signs were positive.The initial laboratory studies showed that the serum concentration of calcium was lower,parathormone was in the low limit of normal range and alkalin phosphatase was normal.An audiography revealed the pattern of sensorineural deafness in all frequencies.Abdominal CT revealed that his right kidney was not observed and creatinine clearance rate was low.After treated with calcium carbonate and vitamin D,the symptoms and the signs were improved.Conclusion HDR syndrome is a rare disorder and less recognized in children,and therefore more attention should be paid to avoid missing diagnosis.

BACKGROUND:There is a lack of safe and effective modular lentivectors in differentiation regulation of embryonic stem cel s. OBJECTIVE:To construct a modular lentivector, Puro-Nanog-hrGFP, with Nanog promoter-control ed humanized renil a reniformis green fluorescent protein (hrGFP) and puromycin and to observe the expression of Nanog during the differentiation of Nanog-hrGFP-transfected mouse embryonic stem cel lines. METHODS:After PCR amplification, Nanog, hrGFP and entry vector were recombined into the pDest-puro vectors to generate the lentiviral expression vector, Puro-Nanog-hrGFP, by the LR reaction. Through lentivirus production, transduction and puromycin screening, the transduced cel lines with Nanog-hrGFP gene were generated and identified. Expression of Nanog during the differentiation of transgenic mouse cel lines was detected. RESULTS AND CONCLUSION:The lentiviral expression vectors Puro-Nanog-hrGFP were constructed successful y by Gateway technology, and then the transducted cel lines were obtained by lentiviral infection. The expression of Nanog was gradual y decreased during the process of transgenic cel lines differentiation, which provides a new tool for further investigation on regulation of stem cel differentiation.

Objective To reveal the role of inhibitor of nuclear factor kappa B kinase alpha (IKKα) in renal inflammation after renal ischemia-reperfusion (IR) injury and its potential associated mechanism.Methods Ischemia-reperfusion injury models were induced in a total of 24 healthy C57BL/6 male mice.Renal function and histological changes were estimated.The expression and site of IKKα,p52,RelB,IL-10 and IL-18 were determined by immunohistochemistry and Western blotting.After the short hairpin RNA(shRNA)targeting IKKα was injected into renal parenchyma,renal function and protein expressions of IKKα,p52,RelB,IL-10,IL-18 were detected.Results Compared with sham-operated group[Scr(7.30±0.13) μmol/L,BUN (8.39± 0.30) mmol/L],levels of Scr [(29.80± 2.10)μmol/L,(27.00±3.40) μmol/L,(23.00±3.70) μmol/L] and BUN [(9.47±3.50) mmol/L,(11.68 ±4.30)mmol/L,(13.12±2.10) mmol/L] were higher on day 1,3,7 and the injury of kidney was serious in IR injury group.Immunohistochemical expression of both IL-18 and IL-10 were increased.Markedly increased IKKα,p52 and RelB protein expression were noted in experiments from day 1 to day 7 during kidney recovery period,with a peak on day 3 and then decreasing toward baseline after day 7.Compared with IR injury group,low-expression of IKKα by injection of shRNA up-regulated the expression of IL-18 and down-regulated the expression of IKKα,p52,RelB and IL-10.Conclusions The NF-κB pathway is activated and IKKα expression is up-regulated during the kidney ischemiareperfusion injury,low-expression of IKKα may block inflammation resolution via down-regulation of alternative NF-κB pathway family members of both p52 and RelB.
