99Tcm-MDP SPECT结合定位CT评价鼻咽癌颅底骨侵犯

Objective Whole body planar bone imaging(WBI)could not accurately evaluate skull base bone involvement(SBBI)due to complex structure of the nasopharynx.The purpose of this study was to preliminarily evaluate the role of SPECT combined localizable CT for diagnosing SBBI of nasopharyngeal cancer(NPC).Methods Forty-four patients with NPC underwent the skull 99Tcm-methylene diphosphonate (MDP)SPECT combined localizable CT,WBI and MRI within a week.Ten patients with non NPC were controls.The region of interest(ROI)of the suspected SBBI(L)was drawn and the same ROI was copied to the upper cervical vertebrae C1 to C3(S)on the 99Tcm-MDP sagittal SPECT imping.The uptake ratio of L and S(L/S)was calculated and the L/S＞1 indicated SBBI.Statistical analysis was performed using nonparametric test(Chi-Square test)or Fisher test.Results (1)There was no increased tracer uptake at the SBB in all controls with L/S=0.66±0.13.(2)Using MRI as the"gold standard",the sensitivity.specificity and accuracy of SPECT combined localizable CT in diagnosing SBBI were 83.3%(20/24),80.0%(16/20)and 81.8%(36/44)respectively,whichwere higber than those of WBI and SPECT alone.whose sensitivity.specificity and accuracy were 70.8%(17/24),70.O%(14/20).70.4%(31/44)and 77.3%(17/22),72.7%(16/22),75.0%(33/44),respectively,but the difference was not significant (X2=2.00,P=0.37).SPECT combined localizable CT correlated well with MRI[X2=17.65.coefficient of contingency(CC)=0.535,P＜0.05 ].(3)There was close correlation between the SBBI and headache since the occurrence rates of the SBBI in headache and non headache groups were 92.9%(13/14)and 36.7%(11/30).respectively,X2=12.16,P＜0.05.However,the differentiation of squanlous cell carcinoma(SCC)did not correlate with SBBI since the occurrence rates of the SBBI in differentiated and non differentiated SCC were 50.O%(19/38)and 83.3%(5/6),respectively,X2=2.69,P=0.19.(4)SPECT combined localizable CT could provide anatomical information,and detect bone destruction in some cases.Conclusion SPECT combined localizable CT bone imaging was an effective method for detecting SBBI of NPC.

多层螺旋CT肠道成像的临床研究

Objective To investigate the value and usefulness of optimized multislice CT enterography (MSCTE) with orally administered isosmotic mannitol (2. 5%) as negative contrast in demonstrating the small bowel and its abnormality. Methods Forty patients suspected of intestinal tumors were randomly divided into two groups and underwent conventional or optimized MSCTE. The expansion degree of bowel lumen and the thickness of bowel wall were evaluated for the six segments of the small intestine. The other 20 patients suspected of gastrointestinal diseases underwent gastrointestinal CT imaging.The expansion degree of bowel lumen and the wall thickness of bowel wall were statistically analyzed with Chi-Square test and t test. Results The wall thickness of the stomach, ileum and colon were (2. 56 ±0.52) ,(1.41 ±0. 15),(1.46 ±0. 13),(1.91 ±0. 25), (1.97 ±0.26),(2.01 ±0. 19), (2. 04 ±0.24)and (2. 05 ±0. 18)mm. Optimized method was superior to conventional method in the expansion degree of the second and third segments of the small intestine (P ＜ 0. 05) . There was no significant differences between two groups in the expansion degree and depiction of mucosa for the other segments of small intestine (P ＞ 0. 05). The gastrointestinal CT imaging was poor in the depiction of the duodenum and jejunum, but stomach, ileum and colon were fully illustrated. Conclusion Optimized MSCTE was superior to conventional method in demonstrating the small bowel, and gastrointestinal CT imaging can expand diagnostic scope because of good observation of whole gastrointestinal tract.

肺移植术前后血清可溶性细胞间黏附分子-1检测的临床意义

Objective To evaluate serum soluble intercellular adhesion molecule-1 (sICAM-1) before and after lung transplantation for diagnosing acute rejection. Methods Biotin-streptavidin time resolved fluoroimmunoassay (BSA-TRFIA) was used to detect the concentration of serum sICAM-1 before and after lung transplantation in 26 patients. All patients were divided into stable lung transplantation group (n =16), acute rejection group (n =4) and infected group (n =6). The serum level of sICAM-1 in those groups was compared with that of the control group ( n = 30 ) by the non-parametric rank sum test ( KruskalWallis H test). Results No significant difference was found for serum sICAM-1 among the three groups and the control group before operation: (357.07 ± 220.01 ), ( 396. 18 ± 136.25 ), (468.95 ± 85.48 ) μg/L vs(348.63 ±69. 12) μg/L, H=6. 0436, P ＞0.05. However, when rejection and infection happened after operation, the serum sICAM-1 increased in the acute rejection group (455.53 ± 126.51 μg/L) and decreased in the infection group (146.43 ± 327.11 μg/L), and the level in the stable transplantation group was (274.23 ± 157.53 ) μg/L (H = 21. 8994, P ＜ 0.01 ). Conclusion Serum sICAM-1 level might be a potential marker to differentiate acute rejection from infection after lung transplantation.
