Objective:To observe the efficacy of different forms of triamcinolone acetonide( TA) in the treatment of buccal erosive oral lichen planus (EOLP). Methods:120 EOLP patients were randomly divided into 4 groups(n=30) and treated with Kangfuxin mouth-wash followed by topical ointment of( TA) , TA injection, TA mouth-wash and only Kangfuxin mouth-wash only, respectively. Before treatment, 1, 2 and 4 weeks after treatment, the pain (VAS score) and erosion area were measured, the effects were compared among groups. Results:The VAS scores of A, B and C groups were significantly lower than those of the control group after 1, 2 and 4 week treatment, and the total effective rate was significantly higher than that of the control group, respectively(P<0. 05). The VAS score was lower and total effective rate was higher in group A and group B than those in group C(P<0. 05), but there was no statistically sig-nificant difference between group A and B(P>0. 05). The average erosion area of group A and B was significantly smaller than that of the control group after 1, 2 and 4 week treatment(P<0. 05). There was no significant difference between group C and the control group after 1 and 2 week treatment(P>0. 05), but 4 weeks after treatment, the average area of erosion of group C was significantly smaller than that of the control group(P<0. 05). Conclusion:Triamcinolone acetonide is effective in the treatment of OLP and the oral oint-ment form is safe and convenient for OLP treatment.

OBJECTIVE: To investigate the value of each single and combined applications of ultrasound thyroid imaging reporting and data system (TI-RADS), ultrasonic shear wave elastography in the diagnosis of thyroid microcarcinoma (TMC). METHOD: 323 patients with thyroid tiny nodules confirmed by surgery and pathology were analyzed prospectively. Then their TI-RADS and shear wave elastography features were summarized. SWE elasticity indices (mean, minimum and maximum value of interest) of nodules were measured. The surgical pathology results were regarded as the gold standard to calculate the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of TI-RADS, shear wave elastography and their combination in the diagnosis of TMC. The receiver operating characteristic (ROC) curve of TI-RADS, shear wave elastography and combined application of both were drawn. The area under the ROC curve were calculated. Furthermore, the value of combined application of both examinations in the diagnosis of thyroid microcarcinoma (TMC) was investigated. RESULT: From 323 nodules,253 were thyroid carcinomas and 70 were benign. Areas under the ROC curves (AUC) of SWE parameters were 0. 648,0. 629 and 0. 605. For SWE, the optimal cut-off value according to ROC curve was SWE_max = 65.50 kPa and SWE_mean = 37.50 kPa. Generally, the sensitivity, specificity, accuracy, PPV and NPV were 88.14%, 82.86%, 87.00%, 94.89% and 65.91% for TI-RADS, and 49.01%, 74.29%, 54.49%, 87.32% and 28. 73% for SWE. There were statistically significant differences in the sensitivity, accuracy, PPV and no statistically significant differences in the specificity, and NPV. The sensitivity,specificity, accuracy, PPV and NPV were 95.26%, 67.14%, 89.16%, 91.29% and 79.66% for combined application of both. The area under the ROC curve of TI-RADS, shear wave elastography and their combination were 0.763, 0.616, 0.804. For nodules ≤ 5 mm, the sensitivity, specificity, accuracy, PPV and NPV were 91.67%, 66.67%, 87.07%, 92.44% and 64.29%. However, for nodules 5-10 mm,the sensitivity,specificity, accuracy, PPV and NPV were 98.50%, 67.44%, 90.91%, 90.34% and 93.55%. CONCLUSION The diagnose of TMC can be further improved by combined application of ultra-sonic TI-RADS and SWE.

Objective:To explore the effects of scout scanning parameters (projection angle and tube potential) on image quality and radiation dose in chest CT and to provide guidance for the selection of scanning parameters in clinical practice.Methods:Different parameter combinations were selected to acquire the scout view of the anthropomorphic adult chest phantom. Fifteen scout views were obtained under parameter combinations of the projection angle (0/90/180 degrees), tube potential (70/80/100/120/140 kV) and tube current (25 mA). And then, chest spiral scans were performed according to the scout views. The other parameters were Assist kV, smart mA (maximum range), 80 mm detector width, 0.992∶1 pitch, 0.5 s rotation time, 330 mm scanning length, 5 mm thickness, NI (noise index) 10. The radiation dose modulation index (ASiR-V) was 30%, and the iterative level was 50%. Volume CT dose index (CTDI vol) and tube current at 4 body levels (pulmonary apex, trachea bifurcation, mammary level and diaphragmatic dome) were recorded. The thermoluminescent dosimeters (TLDs) were used to measure the organ dose of the breast glandular. Regions of interest (ROIs)were selected at the trachea bifurcation and diaphragmatic dome to calculate the contrast noise ratio (CNR). Results:The tube potential of the spiral scanning was automatically selected as 80 kV when the projection angle was 0 degree. The changing of the tube potential for the scout had little influence on the tube current at the four body levels, and the variation range was 0-2% (5/230). The tube potential in the spiral scanning was automatically selected as 100 kV when the projection angles were 90 and 180 degrees. The changing of the tube potential for the scout had a great influence on the tube current at the slice of trachea bifurcation and the variation range was from 14%(29/210)to 44%(93/210). According to the angle projection, there were statistical differences in CTDI vol( P< 0.017), organ dose of the breast glandular, and CNR at the slices of trachea bifurcation and at diaphragmatic dome ( F=13.027, 24.727, 10.630, P< 0.05). According to the tube potential in the scout scanning, there were no significant differences in CTDI vol, organ dose of the breast glandular and CNR at both levels ( P> 0.05). Conclusions:In chest CT, the influence of the projection angle in scout scanning on the image quality and radiation dose was more significant than that of the tube potential.

BACKGROUND: Recently,the technique of isolation procedure of viable islets cell from large animals has been mature and used in clinical islet cell transplantation. Some study results indicate that low yields of pig islet cell isolations is probably not due to the presence of higher or more aggressive enzyme activities during the porcine isolation procedure. Therefore, the causative factors resulting in the inconsistent results should be sought for the intrinsic properties of the pancreatic islet and pancreas. The purpose of the study is to get more pancreatic islet cells for diabetic patients.OBJECTIVE: To investigate the effect of single enzymatic solution (SES)and multi-enzymatic solution(MES) on adult porcine pancreatic islet cell isolation,and to provide the theory base for diabetic patients rehabilitation.DESIGN: A completely randomized and controlled experiment based on animals.SETTING: General surgery and gerontology department in a university hospital.MATERIALS: The experiment was conducted in the Second Affiliated Hospital of Harbin Medical University from June 2003 to May 2004. Twenty consecutive random-bred adult pigs, 12 - 24 months old, weighing average 100 kg,were selected for experiment from Hada Slaughterhouse of Harbin.INTERVENTIONS: After slaughtering,the spleentic lobe of the pancreas was excised using sterile surgical gloves and surgical instruments. Each was immediately transported in 500 mL of sterile RPMI1640 solution at 4 ℃ to the laboratory for processing. After removal of fat peritoneum and superficial blood vessel,each pancreas was first immersed in 1:5 000 Liquor chlorhexidine for 3 minutes,then washed three times with cold RPMI1640, next mechanically minced into 1 mm×1 mm×1 mm fragments,weighed,and equally divided into two groups. Adult porcine islets were isolated with two different collagenase solutions(SES and MES).MAIN OUTCOME MEASURES: Islet count was performed with DTZ-staining. The viability was assessed by trypan-blue staining. Porcine islet insulin-secretory function was assessed by insulin content of cultured porcine islets and by insulin release. Islet morphological integrity was finally established by electron microscope examination.RESULTS: Overall islet cell content were statistically different between the two methods[(1 782 ±427) IE/g vs (1 293 ±451) IE/g,P<0.05]. No significant difference was found in viability,function or morphology of islet between MES and SES(P>0. 05).CONCLUSION: An average of isletisolated with MES method represents a uniquely massive yield in comparison with that by SES method. A good viability was also confirmed by static incubation and culture. The transplantation of those pancreatic islet cells can help to control the syndromes of diabetes.
