Objective To discuss the applied value of multislice spiral CT(MSCT) in diagnosing and localizing the embedded supernumerary teeth. Methods A total of 43 cases with the embedded supernumerary teeth were undergone MSCT using shaded surface display(SSD), minimum intensity projection(MIP) and multiplanar reformation(MPR) to present the form and location of the embedded supernumerary teeth and to determine the surgical style.The result of image was retrospectively analysed after operation.Results The reconstruction images,could clearly show the dental surface image including crown, root, neck and root bifurcation, labial or palatal location, eruption orientation and relation with dentition in anterior maxilla. The position of 52 embedded supernumerary teeth in 43 patients were completely confirmed by surgery with accuracy of 100%. All patients were well healed with no infection and injury to nearby teeth. Conclusion The Embedded supernumerary teeth in bone can be detected by MSCT and MSCT can be used as an important examination technique before surgical and orthodontic treatment.

Objective To explore the factors affecting the collection of allogenic peripheral blood stem cells in donors. Methods Using COBE-spectra blood cell separator to collect peripheral blood stem cells in 21 allogenic donors. The impact of the factors including the number of white blood cell(WBC) and nucleated cell(NC), and mono-nucleated cell(MNC) ratio on the collecting rate of peripheral blood stem cells was analyzed before and after collection. The output of CD 34 +stem cells stimulated by different doses of G-CSF was also analyzed. Results When the mean count of peripheral WBC and MMC in donors was (41?7.7)?10 9/L and 12?2.9% respectively, the count of collected NC was 2.7?0.8?10 8/L, and the number of the collected CD 34 + stem cells was also higher. Statistical analysis showed that the number of NC was significantly related to the collecting rate of CD 34 stem cells(P

Objective:To determine the effect of total parenteral nutrition(TPN) supplemented with glutamine(Gln) on the concentration of plasma lipopolysaccharide(LPS)of the multiple organ dysfunction syndrome(MODS) patients.Methods:40 MODS patients in the ICU were randomly divided into routine group(Group A,n=20),the Gln+TPN treatment Group (Group B,n=20).The two groups of patients received treatment of parenteral nutrition with equal nitrogen and equal calorie.Group A were given routine TPN,and Group B were given routine TPN and Gln 0.27 g/(kg?d)[i.e.dipeptiven 0.4 g/(kg?d)] for seven days.The concentration of plasma Gln and LPS were checked before the treatment of TPN and on the first,the third and the seventh day after the treatment of TPN.At the same time 20 healthy blood donators were chosen as the healthy control group(Group C).Results:Before treatment the concentration of plasma Gln of the two patient groups were both lower than that of Group C(P0.05).On the first,the third and the seventh day of the treatment of TPN,the concentration of plasma Gln of Group A was lower than that of Group B(P0.05).After the treatment of Gln plus TPN,the concentration of plasma LPS of Group B was lower than that of Group A(P0.05).Conclusion:The Gln(dipeptiven) can help to decrease the concentration of plasma LPS and the TPN treatment time of the MODS patients.

AIM: There is a controversial argument about the choice of total hip replacement (THR) and bipolar artificial femoral head replacement (FHR) for elderly patients with femoral neck fracture. This study was designed to explore the long-term biocompatibility and functional recovery of joints in patients over 70 years with femoral neck fracture by THR and bipolar artificial FHR. METHODS: Sixty patients with femoral neck fracture over 70 years were enrolled from the First Department of Bone and Joint Surgery in the First Hospital of Jilin University from January 2002 to December 2006. There were 21 cases (8 males and 13 females) receiving THR, with a mean age of (72.1?3.5) years, and 18 of them were complicated with internal diseases. While 39 cases (16 males and 23 females) received bipolar artificial FHR, their average ages was (75.1?6.4) years, and 35 of them were complicated with internal disease. ①Choice of artificial prosthesis: Sixteen prosthesis were produced by Germany Link Company and American Zimmer Company, 44 artificial joints were offered by Beijing Mengtaiyin Medical Instrument Co., Ltd. ②All the patients were operated by senior doctors who were qualified for post technique owing to more than 10-years working experience about artificial joints. ③The mean time of follow-ups for all patients was 37 months. The difference was compared in biocompatibility between materials and host, joint function, Harris scoring, time of operation, blood loss, time of hospitalization, cost of hospitalization and adverse effect. RESULTS: ①Comparison of biocompatibility: Two revisions for abrasion of acetabular wall were carried out 5 years after bipolar artificial FHR, and there was no infection of incision, dislocation of hip joint or loose of artificial joint in other patients of these two groups. ②Comparison of adverse effect: There was one patient with complications of pain and red swelling of hip in each group. No infection occurred around the prosthesis, and these two patients recovered after symptomatic treatment. ③Comparison of follow-ups for joint function: The average Harris scores was 89.8?8.6 in THR group and 72.7?9.5 in bipolar artificial FHR group, and there were significant differences in these two groups (P 0.05). ⑤Comparison of operation time and blood loss: The average operation time were (150.2?24.3) minutes in THR group and (105.8?22.1) minutes in bipolar artificial FHR group, with significant differences (P
