Objective: To discuss the methods and experience of 64-slice spiral CT which used in infant cases with congenital heart disease, to select the appropriate scan parameters for reducing artifact and the radiation dose. Methods: Thirty-five cases with congenital heart disease were arranged CT examination by using Philips Brilliance 64-slice spiral CT scanner with Blous Tracking techniques. Results: All the images of the heart chambers, pulmonary artery, pulmonary vein, the ascending aorta and the descending aorta contrast agent filling showed good and had clear display. The density of superior vena cava is moderate. The various vascular CT value is approximate, no hardening artifacts. The atrioventricular of Cardiac and vascular of contrast agent filled fully and had clear boundary, no significant artifacts and no effect on the impact reconstruction. Conclusion: Appropriate adjustment of scanning parameters can reduce hardening artifact and the impact of artifacts. Following the principle of as low as reasonably achievable (ALARA) can obtain diagnostic images and reduce radiation damage to the infant.

Objective To investigate the clinical application of fecal calprotectin in inflammatory bowel disease (IBD).Methods Colonoscopy took 79 patients with IBD that were diagnosed with pathology,including 47 cases of ulcerative colitis (UC) patients,32 cases of Crohn's disease (CD).Moreover,42 cases of IBD patients without abdominal pain,diarrhea and other intestinal inflammation were used as disease control group,and 34 cases of healthy people were used as healthy control group.The level of fecal calprotectin in each group was detected by enzyme-linked immunosorbent assay (ELISA).Results The positive rate of fecal Calprotectin in IBD group,disease control group and the healthy control group was 57.0％,19.0％,and 0,respectively; each positive rate in IBD group was significantly higher than the other two groups (P ＜ 0.05).The serum concentration of fecal calprotectin in IBD group [(493.86 ±204.18) μg/g] was significantly higher than the disease control group [(71.46 ± 60.51) μg/g] and the healthy control group [(36.19 ± 13.46) μg/g] (P ＜ 0.05) ; IBD active calprotection [(1015.23 ± 324.96) μg/g] was significantly higher than resting [(52.69 ±34.71) μg/g] (P ＜0.01).Conclusions Fecal calprotectin test benefits early diagnosis of IBD,and may be taken as the diagnostic index of IBD activity.It has extensively clinical value.

AIM: To investigate the process of human bone marrow stromal cells (hBMSCs) differentiation into neural-like cells and to determine the role of 26S proteasome in neuronal differentiation. METHODS: Purified hBMSCs were treated with β-mercaptoethanol (β-ME) for 1 day and retinoic acid (RA) for 3 days, followed by growth factor (10 μg/L bFGF or 20 μg/L NGF) for another 3 days. Immunofluorescence was performed to detect the expression of nestin (a neural precursor cells marker), Tuj1 (a premature neuronal marker), and neurofilament (NF, a mature neuronal marker) at all stages of induced differentiation. Immunostaining and RT-PCR were used to analyze the expression of 26S proteasome during neuronal differentiation of hBMSCs. To further confirm the role of 26S proteasome in hBMSCs differentiation, cells were treated with β-ME/RA and then followed by protesome inhibitor MG132 and growth factor. Immunostaining was performed to detect NF-positive cells. RESULTS: Quantification results showed that the untreated cells were almost never positive for nestin, Tuj1 and NF. After treated with β-ME/RA, the numbers of nestin-positive cells (34.41%±1.27%) and Tuj1-positive cells (27.79%±1.27%) were increased. Notably, the numbers of NF-positive cells were significantly increased to 56.72%±2.4% after induction with β-ME/RA/GF. Immunofluorescence analysis showed that undifferentiated hBMSCs cells were weakly stained by antibody against 26S proteasome, but the numbers of cells with high-intensity of 26S proteasome were increased after treated with β-ME/RA. The RT-PCR result of 26S proteasome further confirmed that the mRNA level of the cells differentiated by β-ME/RA (1.33), as well as by β-ME/RA/GF (1.77), was significantly increased compared to the undifferentiated cells. Moreover, hBMSCs incubated with protesome inhibitor MG132 significantly decreased the numbers of NF-positive cells (37.59%±1.52%). CONCLUSION: After induction with β-ME/RA/GF, hBMSCs can be differentiated into neural-like cells, which is concomitant with the increase in 26S proteasome expression. Inhibitor of 26S protesome prevents hBMSCs differentiation, suggesting that 26S proteasome may be involved in the differentiation of hBMSCs into neural-like cells.

OBJECTIVE: To measure the upper airway of obstructive sleep apnea-hypopnea syndrome by speed CT. We can predict the airway obstruction plane with the airway plane data and compliance in OSAHS patients. Through this measurement, we can provide assistance for clinical diagnosis and treatment. METHOD: This study randomly selected 82 patients diagnosed with OSAHS and 45 cases non-snoring healthy people as control group by the PHILIPS 256-slice CT. The zone volume, sagittal diameter, coronary diameter and cross-sectional area of the narrowest plane in nasopharyngeal area, velopharyngeal area, glossopharyngeal area, hypopharynx area in two groups of quiet respiration and Müller's status were measured. RESULT: In the OSAHS group underwent quiet breathing and Müller movement during CT scanning, the two states about nasopharyngeal coronary diameter, the hypopharynx sagittal diameter and cross-sectional area showed no significant difference, while other groups showed differences between the parameters (P<0.05). There was significant difference (P<0.01) in the velopharyngeal volume, tongue sagittal diameter and volume. Under Müller movement in the OSAHS group and the control group, the hypopharynx volume showed no significant difference. The nasopharyngeal coronary diameter and volume, velopharyngeal cross-sectional area and tongue sagittal diameter were different (P<0.05). The remaining set of parameters showed significant differences (P<0.01). Compared the airway compliance (Müller phase) of the OSAHS group and the control group,the parameters of each group were different (P<0.05), of which the nasopharyngeal sagittal diameter, velopharyngeal volume showed significant difference (P<0.01). Meanwhile, in the same plane, coronary diameter was greater than sagittal diameter (P<0.05) in both the OSAHS group and the control group. The pharyngeal volume measurement was basically consistent to the fiber endoscopy. CONCLUSION The obstruction plate of OSAHS patients is mostly in the velopharyngeal area and glossopharyngeal area measured with a high speed CT. The volume measurement of upper airway with speed CT can predict airway obstruction plate in patients with OSAHS.
