[Objective]To explore the feasibility and outcome of posterior single open-door and pedicle screw in treating canal stenosis and instability of cervical vertebrae at one time.[Method]The preoperative radiographs of 15 patients were measured and were diagnosed to be developmental spinal canal stenosis and instability of cervical vertebrae.MRI showed the spinal cords were compressed obviously.Posterior C_(3~7) single open-door decompression and canal-plasty was adopted.Self-designed pedicle screws and intertransverse fusion were used in the unstable segments.[Result]Complications were not found after the operation.The postoperative radiographs showed that the screws were in the right places.The average follow-up time was 13 months,ranging from 7 to 18 months.The short-term radiographs showed firmly fixed screws.[Conclusion]It is a simple and reliable method to treat canal stenosis and instability of cervical vertebrae at one time with posterior single open-door and pedicle screw.Anterior and posterior operations have been avoided and the short-term outcome is satisfied.

Objective The study consisted of two parts: in part Ⅰ the effects of propofol or/and procaine on CD18, CD62L expression and superoxide anion (SOA) release of phorbol 12-myristal 13-acetate(PMA) stimulated human neutrophils (PMNs) were studied in vitro; in part Ⅱ the effects of propofol or/and procaine on IL-6 and TNF-?production in endotoxin-stimulated human whole blood were studied. Methods PMNs were separated from the whole blood obtained from healthy 20-40yr old subjects. Part Ⅰ consisted of 9 groups: in group 1 (control) phosphate buffer solution was added to PMNs; in group 2 PMNs were stimulated by PMA 100mg?ml-1 ; in group 3-5 different concentrations of propofol (0.4, 4.0,40?g?ml-1) were added to PMA stimulated PMNs; in group 6-8 different concentrations of procaine (1.5,15,150?g?ml-1 ) were added to PMA stimulated PMNs; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to PMA stimulated PMNs. Part II also consisted of 9 groups: in groupl whole blood was mixed with normal saline; in group2 lipopolysaccharide (LPS) l?g?ml-1 was added to whole blood; in group 3-5 different concentrations of propofol (0.4,4.0,40?g?ml-1) were added to LPS stimulated whole blood; in group 6-8 different concentrations of procaine (1.5, 15, 150?g?ml-1 ) were added to LPS stimulated whole blood; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to LPS stimulated whole blood. CD18, CD62L expressions were measured by flow cytometry. SOA release was determined by cytochrome C reduction in the presence or absence of superoxide dismutase (SOD) . IL-6 and TNF-? production were measured by using radioimmunoassay. Results Propofol or/and procaine depressed CD18 up-regulation, CD62L shedding and SOA release of PMA-stimulated PMNs and propofol was more effective than procaine. Propofol enhanced but procaine inhibited the increased production of TNF-? and IL-6 in the LPS stimulated whole blood but when propofol and procaine were used in combination. The effectof procaine predominated. Conclusions Propofol or/and procaine can attenuate tissue damage induced by neutrophils by inhibiting the function of neutrophils.

Objective To evaluate the clinical value of bedside echocardiography in full term infants in NICU.Methods The bedside echocardiography was performed for 313 full term infants,and then they were ana-lyzed.Results The main clinical characteristics of totally 313 cases of neonates were tachypnea,heart murmur and cyanosis.Patent foramen ovale and patent ductus arteriosus were common in the no cyanotic blood shunt,no cyanotic congenital heart disease(CHD)was mainly made of atrial septum defect(31 cases),followed by ventricular septal defect (20 cases).Cyanotic CHD was made of pulmonary atresia(6 cases),complete transposition of great artery (5 cases),tetralogy of fallot(5 cases),total anomalous pulmonary venous drainage(5 cases).Tricuspid regurgitation was common in abnormal blood flow,moderate to severe pulmonary hypertension was common for full term infants. Conclusion There were many abnormal echocardiography examination results,and atypical noise was common in neonatal CHD,routine examination of bedside echocardiography for full term infants in NICU was important for early detection of CHD and may help treatment timely to improve the prognosis.

Objective To investigate the reliability of Berg Balance Scale (BBS) applied in patients with Parkinson's disease (PD). Methods 121 PD inpatients from March to December, 2011 were assessed with BBS by 2 raters, and the testing procedure was videoed. One of the raters assessed with BBS via video 4 weeks later. The intraclass correlation coefficient (ICC) and Kappa coefficient between raters and between tests were investigated. Results The ICC was 1.00 of the total score between raters and 0.99 between tests, while the Kappa co-efficient were 0.66 to 0.93 and 0.69 to 0.99 of the items. Conclusion BBS is reliable in interrater and test-retest as applied in PD patients.

Objective To explore the effects of Sinomenine (Sin) on phenotype transdifferentiation in renal tubular epithelial cells. Methods Mice primary tubular epithelial cells and cell line (MCT) were cultured in vitro. Model group cells were stimulated by IL-1?(10 ng/ml). The cells of Sin group were co-incubated with Sin(10, 100 ,500?mol/L) simultaneously. The cells without IL-1?and Sin treatment were regarded as control group. The protein expression of?-smooth muscle actin (SMA) and Vimentin was assessed by immunohistochemistry and Western blotting. The mRNA expression of?-SMA and Vimentin was examined by RT-PCR. Secretion of matrix metalloproteinases was determined by zymography. Results The mRNA expression and protein level of?-SMA and Vimentin, and the enzyme activity of MMP-2 and MMP-9 in tubular epithelial cells stimulated with IL-1?were significantly higher than those in the controls. Sinomenine significantly reduced the expression levels of protein and mRNA of?-SMA and Vimentin. At the same time, the MMP-2 and MMP-9 activities were reduced markedly. Conclusion Sinomenine can decrease the transdifferentiation in renal tubular epithelial cells stimulated by inflammatory factor IL-1?and prevent renal interstitial fibrosis.

Objective To investigate the effect of taurine on iron bioavailability in rats and its possible mechanism. Method SD rats were randomly divided into three groups:normal group (NG),taurine treated group (TG),experimental control group (EG). TG and EG were induced to be anemic experimentally for 4w before the study. Then the rats were fed iron supplements for 25 d,meanwhile TG was treated with taurine following hemoglobin(Hb) repletion bioassay. Regression analysis of TG and AG were measured following Hb repletion bioassay using iron supplements. And the relative biological value of TG following Hb repletion were calculated. The serum iron,unsaturated iron-binding capacity(UIBC),total iron-binding capacity(TIBC),transferin saturation(TS)and the expression of hepcidin were detected. Results The iron bioavailability of TG was higher than EG,and the RBV of TG was 126%. Other hematological variables of TG were close to NG,and better than EG. The expression of hepcidin was increased compared with NG,but decreased compared with EG. Conclusion Taurine can improve iron bioavailability in rats via suppressing hepcidin expression in rats.

Objective:To investigate the effects of Tripterygium Wlilfordii on renal interstitial fibrosis and the expression of inflammatory factor in mice kidney with the Unilateral Ureteral Obstruction(UUO).Methods:Mice were randomly assigned to shame operation group(shame proup), UUO group, Tripterygium Wlilfordii and ACEI treatment group after UUO. The protein expression of ?-SMA,ICAM-1 were assessed by immunohistochemistry or Western blot; MCP-1 mRNA were detected by reverse transcription-polymerase chain reaction analyses(RT-PCR). And the change of renal pathology was observed at the same time.Results:In comparison with the shame group, the protein levels of ?-SMA, ICAM-1 and the mRNA expression of MCP-1 in UUO mice and treatment groups increased significantly, meanwhile Tripterygium Wlilfordii and ACEI could significantly reduce the expression of ?-SMA, ICAM-and MCP-1 on levels of protein and gene. The effects of Tripterygium Wlilfordii on ICAM-1 and MCP-1 were more significant than ACEI.Conclusion:Tripterygium Wlilfordii could reduce the transdifferentiation of renal interstitial cells and prevent renal interstitial inflammatory injury.
