[Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in spinal tuberculosis.[Method]Forty-one patients with histologically confirmed spinal tuberculosis underwant imaging examinations.Forty-one patients were performed CR,22 CT and 31 MRI.[Result]CR of 38 patients clearly revealed bone changes and narrowed or disappeared disk space.CR of 30 patients well showed the abnormal soft tissue.CT scan of 22 patients clearly depicted calcification and no abnormal was found in pedicles in all the 22 CT scans.CT scan of 21 patients revealed bone changes of vertebral bodies and CT scan of 20 patients showed abnormal soft tissue.The soft tissue was involved in all 31 patients with spinal tuberculosis.Diskspaces were involved in 29 cases and the pedicles were normal in all 31 case.The lesions showed hypointense in T1 scan primarily,hyperintense in T2 scan primarily.[Conclusion]CR is the first imaging approach for spinal tuberculosis.CT well reveal the extent and minute calcification.The extent,abnormal soft-tissue and abnormal disk space are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of spinaltubereuinsis.

[Objective]To investigate the value of 16-slice spiral CT(MSCT)postprocessing in styloid process in vivo and provide the vivisection data for diagnosing and curing styloid process syndrome.[Method]Totally 100 volunteers with normal styloid processes underwent 16-slice spiral CT(MSCT). Based on the initial datum,4 kinds of postprocessing including multiple planar reconstruction(MPR), curve planar reconstruction(CPR),surface shaded display(SSD) and volume rendering (VR) were performed.The length and inclination angle of stytoid processes were measured. The distance of between styloid processes and carotid canal external aperture,jugular foramen, stylomastoid foramen ,mastoid process, internal carotid artery and internal jugular vein were surveyed. [Result]The average length of styloid processes was 24.51 mm?3.05 mm, left was 24.33 mm?3.15 mm and right was 24.69 mm?2.95 mm. The anterior inclination angle was 19.35??2.92? and medial was 24.00??4.07?.The distance of between styloid processes and carotid canal external aperture, jugular foramen,stylomastoid foramen ,mastoid process , internal carotid artery and internal jugular vein were 8.53 mm?2.45 mm, 2.87 mm?0.88 mm, 2.34 mm?0.74 mm, 17.23 mm?1.85 mm,6.49 mm?1.58 mm and 3.70 mm?1.46 mm respectively. [Conclusion]Sixteen-slice Spiral CT postprocessing demonstrate the stytoid processes in vivo accurately and fully, among which multiple planar reconstruction and surface shaded display are more valuable, because they can evaluate the length and inclination of the styloid processes and the distance between the processes and their surrounding structures in vivo more accurately.

ResultsVAS scores decreased significantly in group Ⅱ and group Ⅲ compared with that in group Ⅰ ( all P ＜ 0.05) ;There were no differences of Ramsay scores between groups ( all P ＞ 0. 05) ;There were three cases of respiratory depression in group Ⅲ. ConclusionPCSA with sufentanil (0.06μg/kg) had exact analgesic effects for postoperative abdominal surgery patients with less adverse reactions.

Background Pterygium is a relatively common eye disease,but its aetiology and pathogenesis remain uncertain.At present,the study on pterygia focuses on understanding its underlying mechanism.Objective This study was to detect the expression of 8-hydroxy-2'-deoxyguaine (8-OHdG),a marker of oxidative damage of DNA,and bcl-2,a gene related with apoptosis,on the pterygium tissue.Methods Thirty pterygium tissue specimens were obtained during the surgery with the primary pterygium 24 cases and recurrent pterygium 6 cases.In addition,20 normal conjunctival specimens from retinal detachment surgery and strabismus surgery were collected.The expressions of 8-OHdG and bcl-2 in pterygium tissue were detected using immunochemistry and compared with the normal conjunctival tissue.The difference in the expressions of 8-OHdG and bcl-2 among different specimens was compared by x2test,and the relationship between 8-OHdG expression and bcl-2 expression was evaluated by Kappa test.Results The positive expressing rate of 8-OHdG in the pterygium tissue was 62.5％ and 83.3％ in the primary and recrudescence pterygium tissue,respectively,but the expression of 8-OHdG was absent in the normal conjunctiva tissue.No significant difference was found in the positive expressing rate of 8-OHdG between primary and recrudescence pterygium tissue(x2 =0.938,P＞0.05).The bcl-2 expressing rate was 90.0％ and 87.5％ in the primary and recrudescence pterygium tissue,respectively.However,that in the normal conjunctival tissue was absent.No significant difference was seen in the bcl-2 expression rate between primary and recrudescence pterygium tissue (x2=0.833,P ＞ 0.05).Of the 27 pterygium tissue with bcl-2 positive expression,8-OHdG showed the positive expression in 20 specimens,and 3 specimens with the bcl-2 negative response were absent reactive to 8-OHdG,showing insignificant difference between them (P＞0.05).The relationship between 8-OHdG expression and bcl-2 expression was concord in a certein extent (Kappa =0.464).Conclusions The upregulation of 8-OHdG in the pterygium tissue indicates that oxidative damage of DNA plays a role in the development of pterygium.Oxidative damage of DNA caused by ultraviolet may be an upriver factor,which induces raising up of expression of bcl-2 and inhibits the apoptosis of normal cells and further proliferation of the conjunctiva tissue,resulting in the genesis and development of pterysium.

Objective To investigate the effect of oral exercise method combined with shaker exercise on dysphagia in patients with cerebral hemorrhage.Methods 112 patients with dysphagia caused by cerebral hemor-rhage were randomly divided into control group (28 cases,conventional treatment),oral exercise method group (28 cases,conventional treatment combined with oral exercise method),shaker exercise group (28 cases,conventional treatment combined with shaker exercise)and combination group (28 cases,conventional treatment combined with oral exercise method and shaker exercise).Four groups were assessed with video fluoroscopic swallowing study (VF-SS)before treatment and after treatment.Results (1)There were no differences on VFSS among four groups before treatment (P >0.05).After treatment,there were significant differences on VFSS among four groups(F =9.40,P <0.05).Combination group[(8.68 ±4.74)points]with the highest score,followed by shaker exercise group[(6.52 ± 3.12)points]and oral exercise method group[(6.43 ±2.84)points],control group[(3.96 ±2.02)points]with the lowest score.There were no differences on VFSS between before treatment and after treatment in control groups (F =0.945,P >0.05).In the remaining groups,the scores of VFSS after treatment were significant higher than that of before treatment (P <0.05).(2)The total effective rate in combination group was higher than that of the remaining groups(χ2 =37.76,P <0.01).Combination group (96.43%)combined with the highest total effective rate,followed by shaker exercise group (75.00%)and oral exercise method group (71.43%),control group (21.42%)combined with the lowest total effective rate.Conclusion The application of oral exercise method combined with shaker exercise on patients with dysphagia caused by cerebral hemorrhage could improve the swallowing function.

BACKGROUND: Carbamylated erythropoietin (CEPO) cannot only remarkably promote the prognosis of cerebral infraction, but also improve the microcirculation. OBJECTIVE: To explore the underlying mechanism of CEPO promoting the microcirculation following cerebral infraction. METHODS: 150 Wistar rats were selected, and 120 rats were used for establishing the models of cerebral infarction, followed by allotted into four groups. The model rats were treated with 500, 1000 and 2000 u/kg CEPO as experimental groups, and those received no treatment as model group. The other 30 rats were as controls. Vascular endothelial cells were isolated and cultured in vitro, and the cell proliferation was detected by cell counting kit-8 assay. The expression levels of proliferation-related genes (Ki67 and p16) and vascular endothelial growth factor (VEGF) were detected using western blot assay. After selective silencing of VEGF through RNA interference, all above indicators were detected again. RESULTS AND CONCLUSION: Cell counting kit-8 assay results showed that the proliferation ability of vascular endothelial cells was increased with CEPO concentration increasing. Western blot assay results showed a significant upregulation of Ki67, p16 and VEGF. After shRNA-VEFG interference, these indicators had no positive correlation with the increased concentration of CEPO. Our findings indicate that CEPO can improve the proliferation of vascular endothelial cells in an animal model of cerebral infarction via upregulating the VEGF expression.

Objective To explore the relationship between the expression of basic fibroblast growth factor (bFGF) and microvessel density(MVD)in non-small cell lung cancer.Methods The expression of bFGF and MVD were observed in 54 eases of NSCLC were detected with in situ hybrldization and immunohistochemical detection.Resuits The expression of bFGF and MVD was greater in adenecarcinomas than in squamous cell carcinomas of NSCLC (P＜0.05).The expression of bFGF was significantly different among the three groups of both squamous cell carcinomas and adenocarecnomas with varying differentiation (P＜0.05).There was hisher bFGF expression and greater MVD in NSCLC patients with regional lymplmode involvement and those with laterdistant metastasis(P＜0.05).Condusion bFGF may play an important role in tumor angiogenesis and lymphatic metastasis of human NSCLC,and detection of bFGF may be a good metastasis and prognostic predictors for human NSCLC.
