Purpose To describe the normal appearances of skull on 3D-reconstruction of Multi-slice CT in adult.Materials and Methods 130 patient data of Volume CT digital subtraction angiography (VCTDSA) with cephalocervical and cephalic vessel that were checked at our hospital from May to July 2009 were analyzed.All of them were subjected to 3D reconstruction of the skull by volume render (VR) and maximum intensity projection (MIP).The anatomy of skull,vascular grooves,pacchionian impressions,the types and closure status of cranial sutures were observed.Results 27 pacchionian impressions (20.77%,27/130) and 51 vascular grooves (39.23%,51/130) were detected.There were three types of the general shapes of cranial sutures:Ⅰconventional type(86.15%,112/130),Ⅱfontanelle ossification type(5.38%,7/130) and Ⅲcranial suture within a cranium (8.46%,11/130).Furthermore,Status of each suture closure were divided into five types:typeⅠcomplete closure(3.0%,16/531);typeⅡgomphosis(78.3%,416/531);typeⅢ sutural bone (7.0%,37/531);typeⅣincomplete closure(3.6%,19/531),the average width of non-closed suture was 1.41mm±0.70mm;typeⅤmixed type (8.1%,43/531).Conclusion 3D reconstruction of multi-slice computed tomography is proved to be a reliable technique capable of defining anatomy of skull.Better than MIP to displays three-dimensional structure VR,but to display cranial sutures,vascular grooves,pacchionian impressions MIP is more definite and hypersensitive.Status of each suture closure may be divided into five types,and the general shapes of cranial sutures may be divided into three types.

BACKGROUND:In treatment of lumbar diseases, lumbar fusion therapy fails in 20%of cases and may lead to a series of complications such as pain, intervertebral space col apse, and delayed kyphosis deformity.
OBJECTIVE:To observe the effect of nucleus pulposus on interbody fusion after removing the anterior column disc of rabbit lumbar vertebra.
METHODS:A total of 36 healthy Japanese white rabbits were randomly and equal y divided into three groups, with 12 rabbits in each group. (1) Group of anterior longitudinal ligament+bone grafting:The L3 intercalated disc were wel exposed and anterior longitudinal ligament was stripped, obtaining a space to L3 intercalated disc, then the iliac bone was implanted. (2) Group of excising anterior 1/3 disc+bone grafting:After the anterior 1/3 disc tissue was excised, the iliac bone was implanted and sutured as Group of anterior longitudinal ligament+bone grafting. (3) Group of excising anterior 1/3 disc+fixation:After the anterior 1/3 disc tissue was excised, the iliac bone was implanted and the anterior column fixation was performed.
RESULTS AND CONCLUSION:Biomechanical testing showed that, at 12 weeks, the verticality tensile force in the group of anterior longitudinal ligament+bone grafting was obviously higher than other two groups, and have better fusion rate and could bear stronger force. Lateral position lumbar radiography showed that, the bone graft was absorbed and no new bone grew into the intervertebral space in the group of excising anterior 1/3 disc+bone grafting at 12 weeks;the formation of osseous bridge was found in the group of excising anterior 1/3 disc+fixation;complete bony fusion was found in the group of anterior longitudinal ligament+bone grafting. Histological examinations showed that, at 12 weeks, no bone tissue formed in the group of excising anterior 1/3 disc+bone grafting;a smal amount of bone trabecula and osteocytes were observed in the group of excising anterior 1/3 disc+fixation;a great quantity of newborn bone trabecula and osteocytes, remodeling lamel ar bone and canalis haversi structure were observed in the group of anterior longitudinal ligament+bone grafting. The stability of anterior column has notable effect on interbody fusion, after the anterior column disc is destroyed, the free nucleus pulposus may affect spinal fusion, so restoring the stability of the anterior column may promote interbody fusion, but stil cannot get solid spinal fusion.

Aim To investigate the effect of total flavonoids of Chrysanthemum indicum on proliferation of synoviocytes and TRAIL/TNF-? expression of synovial tissue with adjuvant arthritis rats.Methods SD rats were divided randomly into six groups including normol,model,TFC(84,168,336 mg?kg-1)and control drug Tripterygium glycosides(30 mg?kg-1)groups.Adjuvant arthritis rat model was induced by a single intradermal injection of 0.1 ml of the complete Freund's adjuvant into the the right hind feet pads of the SD rats.The proliferation of synoviocyte was measured by MTT;The expression of TRAIL and TNF-? on synovial tissue were detected by means of immunofluorescence.Results TFC was shown to suppress the excessive synoviocyte proliferation;The expression of TRAIL was lower in model group than that of the normal group.TFC can increase the expression of TRAIL protein;The contrary to TNF-? protein.Conclusions TRAIL play a role in the development of AA.TFC can increase the lower expression of TRAIL protein,that maybe one of the mechanisms of TFC improvement AA.

Objective To evaluate the feasibility of CT subtraction angiography of the cerebral vessels with synchronous matched mask bone elimination (MMBE) technique, and to compare the imaging quality of MMBE with that of volume computed tomographic digital subtraction angiography (VCTDSA). Methods Vascular Vascular model was scanned with 64-slice spiral CT. Synchronous and asynchronous scans were independently performed for 10 times without contrast medium injection. ②Then with contrast medium injection, the same scans mentioned above were repeatedly performed each for 5 times. The imaging quality of MMBE was analyzed, which were reformatted and displayed with 3D volume rendering (VR) and maximum intensity projection (MIP). CT value of the overall view was measured on subtracted images (without contrast medium). Two sets of bone masks were extracted for subtraction and the imaging quality was evaluated (without contrast medium). Also the imaging quality of VCTDSA was compared with that of synchronous MMBE. Results With synchronous and asynchronous scan,imaging quality of MMBE was rated grade Ⅱ in 13 and grade Ⅲ in 2 times. There was no significant difference in the average CT value of subtracted images between the two methods(P>0.05). With synchronous scan, imaging quality of subtracted bone mask was rated gradeⅠ in 10 times. While with asynchronous scan, 1 time was grade Ⅰ, 8 were grade Ⅱ and 1 time was grade Ⅲ. The imaging quality of synchronous MMBE was rated grade Ⅱ in 13 times, grade Ⅲ in 2 times. For VCTDSA, the imaging quality was rated grade Ⅰ in 15 times. Conclusion Synchronous MMBE is a feasible imaging method for evaluation of cerebral vessels. The subtracted image quality is significantly improved with this technique. Imaging quality of VCTDSA is still superior to that of synchronous MMBE.

OBJECTIVE:To provide reference for further formulation of the rational use of vancomycin. METHODS:Retro-spective analysis was conducted on the related information of discharged patients who intravenously used vancomycin from Jun. 2013 to Dec. 2014. RESULTS:178 patients were enrolled,with average age of 59.6 and 73.60% male,who were mainly with lung infectious(74.72%). Support examinations were sufficient before using of vancomycin. 66.29% patients were empirically giv-en vancomycin with pathogenic detection rate of 85.39%. 71.91% patients were conducted therapeutic drug monitoring with only 47.54% of first blood samples achieved the target range. CONCLUSIONS:Vancomycin application is generally rational in our hos-pital. However,issues like duration of empirical therapy,rational therapeutic monitoring,and individualized start dosing still need to be noticed.
