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.

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 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.

Objective To examine the association of urinary neutrophil gelatinase-associated lipocalin(NGAL) and interleukin 18(IL-18) with acute kidney injury (AKI) in patients after cardiac surgery. Methods Thirty-three patients undergone cardiac surgery were divided into AKI group and non-AKI group according to the AKI criteria. The Scr, urinary NGAL and IL-18 were measured at different time points. Results Nine of 33 patients (27.27%)developed postoperative AKI, and Scr concentration in AKI group reached its peak within 12-48 hours after cardiac surgery. Urinary concentrations of NGAL and IL-18 at 2 h and 4 h after cardiac surgery were significantly higher than those before operation in AKI patients (P<0.01). The urinary concentrations of NGAL at each time point and that of IL-18 at 2 h and 4 h after cardiac surgery in AKI patients were significantly higher than those in non-AKI patients. After correction by urinary creatinine, the differences of NGAL/Ucr and IL-18/Ucr ratios were still significant (P< 0.01). For concentrations of urinary NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after surgery, sensitivities and specificities were good with cutoff values at 250 μg/L, 250 μg/mmol and 1800 ng/L, 1800 ng/mmol, respectively. Urinary concentration of NGAL at 2 h after cardiac surgery was positively correlated with Scr at 12 h postoperation in AKI group (r=0.638, P<0.05).Conclusions The incidence of AKI in patients after cardiac surgery is quite high. Urinary concentrations of NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after cardiac surgery are the early diagnostic markers for AKI, among which urinary NGAL/Ucr is the most sensitive one.
