[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.

AIM: To evaluate the quality of Rhizoma gastrodiea processed by different drying methods. METHODS: Vacuum freeze drying and oven drying were adopted. The content of gastrodin was determined by RP-HPLC. RESULTS: The content of gastrodin of Rhizoma Gastrodiae processed by vacuum freeze drying was significantly higher than that by boil with water and oven drying. CONCLUSION: The method of vacuum freeze (drying) can prevent Rhizoma Gastrodiae from degradation of gastrodin, to keep the appearance, to make Rhizoma Gastrodiae convenient for further processing.

Group Ⅰ :sufentanil 0. 04μg · kg-1 ·h-1 for postoperative analgesia; Group Ⅱ : sufentanil 0. 06μg · kg-1 · h-1 for postoperative analgesia; Group Ⅲ :sufentanil 0.08μg/kg · h for postoperative analgesia;PCSA started at the end of operation with catheter buried in deltoid muscle. Visual analgesia scale(VAS) ,Rasmay scale and side effects were recorded at 4,8,16,24 and 48h after operation. 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.

Objective To investigate the effect of continuous positive airway pressure (CPAP) on seizure frequency in epilepsy patients complicated with obstructive sleep apnea (OSA). Methods Subjects were divided into CPAP group (20 subjects) and medication group (22 subjects) according to whether they can tolerate CPAP. CPAP group were treated with CPAP combined with antiepileptic drugs. Medication group were treated with antiepileptic drugs alone. Seizure frequency and apnea-hypopnea index (AHI) were compared between groups before and after 4 weeks and 24 weeks of treatment. Results Baseline seizure frequency and apnea-hypopnea index (AHI) were compared between groups(P>0.05). A sig?nificant reduction of seizure frequency was observed in CPAP group after 4 weeks and 24 weeks of treatment compared to that before treatment (P<0.01). In medication group, no significant difference in seizure frequency was noted betweem 4 weeks and 24 weeks after treatment compared to that before treatment(P>0.05). A significant reduction of AHI was ob?served in the CPAP group after 24 weeks of treatment compared to that before treatment (P<0.01), but no change of AHI by treatment was observed in medication group (P>0.05). Conclusion Treatment of OSA in patients complicated with epilep?sy may improve seizure control in short and long term, but longer observation time and more samples are needed for further research.

Objective To explore the value of multi-model reconstruction of 16-slice spiral CT in diagnosis of rib fractures.Methods 16-slice spiral CT volumetric scanning was performed in 72 patients with rib fracture proved by clinical,all images were reconstructed in thin slice and transferred into ADW4.1 workstation.Images such as multiplanar reconstruction(MPR),maximum intensity projection(MIP)and volume rendering(VR)were performed,then the reconstructed images of injured ribs were observed and analyzed by two experienced radiologists and compared with radiographs.Results In 72 cases,there were 217 rib fracture and 7 costal cartilage fracture depicted on MSCT.The location and number of fracture and displacement of fracture could be showed clearly on images of multi-model reconstruction.VR images were betten in demonstration of the anatomical structure,MPR images were better to show the minor lesion of rib fracture,MIP was the best imaging method in detecting the costal cartilage fracture,while axial image was the basic CT scanning section.Radiographs revealed 169 rib fractures but no costal cartilage fracture.Conclusion 16-slice spiral CT of multi-model reconstruction is superior to radiography in diagnosis of rib fracture and costal cartilage fracture.But the combinalion of various reconstruction techniques should be acquired.

OBJECTIVE: To explore the association between low flow rate and reperfusion injury during the process of preserving liver by cold machine perfusing perfluorochemical oxygen carder solution. METHODS: Forty-four male adult Wister rats were randomly divided into normal, control, experimental Ⅰ and experimental Ⅱ groups. In the normal group, the removed liver was performed isolated reperfusion guided by Clavien method. In the other 3 groups, the removed liver was infused through the portal vein by the 4-5 ℃ conserved perfluorochemical oxygen carder solution. The infused rate was controlled at 0.4, 0.2, 0.1 mL/(min·g) with 18 hours perfusion, After that, isolated reperfusion was performed. The activity of aspartate aminotransferase, alanine transaminase and endotheiin mass concentration of the effluent was detected at minutes 10, 30, and 60 after reperfusion. The histopathological changes of liver under light and election microscopy were also observed. RESULTS: The activity of aspartate aminotransferase, alanine transaminase and endothelin mass concentration had no remarkable differences between the experimental Ⅰ group and control group (P > 0.05). The differences between the experimental Ⅱ group and control group were remarkable (P < 0.05). The light and electron microscopy showed that the histopathological changes of liver in the control and experimental Ⅰ groups was lightener than experimental Ⅱ group. CONCLUSION: During the process of preserving liver by cold machine perfusion, the rate of 0.1 ml/(min·g) perfluorochemical oxygen carder solution increase the injury of hepatocyte and sinusoidal endothelial cells, which eventually result in severity of reperfusion injury.
