Objective To search for a better way than DSA to display the bronchial arterial (BA) supply of spinal cord, esophagus, trachea, etc., and for further evaluation of BA supply to the above structures, along with reducing the complications of trans-BA infusion and/or embolization. Methods Multislice CT angiography of BA (BA-MSCTA) was performed on 19 patients suffering from lung cancer or hemoptysis due to bronchiectasis after undergoing digital subtraction angiography BA (BA-DSA). Totally 10ml of 45% contrast medium was injected into BA (1~2 ml/s), BA-MSCTA was started 5 s after the injection, scanning from low cervical region to the bottom of lung (collimation: 5 mm; no overlapping reconstruction ). The intra-spinal canal, esophagus, trachea, etc. were enhanced. Results On BA-DSA, except one case in which a bronchial artery was faintly displayed, no spinal artery, intra-spinal canal, esophagus or trachea enhancement could be demonstrated. While on BA-MSCTA, intra-spinal canal associated with an intercostobronchial trunk enhancement due to truncus formation were observed in seven cases, including five cases of spinal enhancement (5/19,26.3%). 15 cases of esophageal enhancement and 18 cases of tracheal enhancement were also observed. Conclusion BA-CTA is superior to BA-DSA in displaying the BA supply of spinal cord, esophagus, trachea, etc.. Spinal arteries are more likely to appear in intercostobronchial truncus cases.

Objective To investigate the value of multislice spiral CT in evaluating the parametrial invasion of cervical carcinoma. Methods 75 cases of FIGO staging II cervical carcinoma who had received the surgery were studied. Their imaging and the FIGO staging were analyzed retrospectively. Results For FIGO staging, the accuracy for evaluating the parametrial invasion was 53.3%(40/75), the rate of underestimation was 26.7%(20/75), the rate of overestimation was 20.0%(15/75); For CT, the accuracy of evaluating the parametrial invasion was 69.3%(52/75), the rate of underestimation was 14.7%(11/75), the rate of overestimation was 17.3%(13/75). In 40 cases, both FIGO staging and evaluation by CT were consistent with the surgical results. In 35 cases, FIGO staging was different from the surgical results. In 29 cases, evaluation by CT was different from the surgical results. In 10 cases, CT could correct the error of FIGO staging. Conclusion CT scan can acquire the multi-plane image, and can directly reflect the parametrial space. It is more accurate than FIGO staging, and is an important complement to FIGO staging.

Objective To have insight into the epidemiological situation and to predict the possibilities for achieving the national goal of basic eradication or the WHO target of elimination of leprosy as a public health in the leprosy high- endemic areas in China. Methods Based upon the data during 1983- 1996 from the National Leprosy Recording and Reporting Surveillance System and using the appropriate mathematical models, the expected calendar year of reaching the national goal in terms of detection and prevalence rates and the WHO target of elimination under different conditions was predicted. Results Of 337 counties where the national goal of basic eradication of leprosy had not reached and 40 counties where the WHO goal of leprosy elimination had not achieved in 1996, the detection rates in calendar years followed the negatively exponential models with a significant goodness- of- fit in 67 and 11 counties, respectively. In the former, the national goal can be met in 6% of counties before the year 2000 or 34.4% before 2010 in terms of detection rate, or 31.3% before the year 2010 in terms of prevalence rate. In the latter, the WHO target can be met in 8- 10 counties within this century when the duration of disease was determined with the WHO definition. While the MB proportion among new cases increased by 10% , the target would be met one year later. However, at the same MB proportion, the change of the duration of completing the fixed treatment from PB 0.5 year and MB 2 years to PB 0.75 year and MB 3 years will result in the achievement of the goal 2- 10 years later. Conclusion The results imply that WHO goal of leprosy elimination can be reached in more than 95% of counties by the end of this century, but the national goal of achieving basic eradication of leprosy in more than 95% of counties by this century will not be met, indicating that leprosy control will go beyond the century in China.

Objective To analyze the detection modes of leprosy and their influencing factors and outcomes. Methods Based upon the nationwide registration of leprosy patients detected during 1981~ 1998, the profiles of these patients at detection were studied. Results The proportions of cases significantly correlated with calendar years in the detection by dermatologic clinic, contact check, clue survey and mass survey, showing a significant increases in percentage of cases detected through dermatologic clinic and contact check and decreases through clue survey and mass survey. Detection of leprosy cases through dermatologic clinic and voluntary reporting became the main modes of case- finding during 1997- 1998, accounting for 37.3% and 28.6% respectively, whereas contact check only accounted for 9.1% . More MB patients were detected by voluntary reporting than PB, whereas detection by dermatologic clinic resulted in a significantly higher proportion (38.0% ) in PB patients than in MB (33.5% ). The voluntary reporting and clue survey resulted in higher proportions of detection in prefecture and county rural areas. In areas with good facilities of dermatologic services, significantly higher extent (75.9% ) of cases were detected through dermatologic clinic, whereas the voluntary reporting and clue survey were main modes of case detection in endemic areas. A great majority of cases were confirmed by leprosy units even though they were detected by various modes. Only 6.5% of leprosy cases were detected and consequently confirmed by doctors in dermatologic clinics. Conclusion This study emphasizes the importance of providing training on leprosy to the doctors in dermatologic clinics while continuously encouraging their involvement in leprosy control.

Objective To study clinical characteristics and the trends of leprosy relapse cases after dapsone(DDS) monotherapy or multidrug therapy(MDT) from 1949 to 1998. Methods The data of leprosy relapse cases in China from 1949 to 1998 were analyzed. Results There were a total of 12 403 leprosy relapse cases during 1949~ 1998 in China with a cumulative relapse rate of 3.28% . Among them, 11 803 were relapsed after DDS monotherapy with a relapse rate of 3.83% and 236 were after MDT with a relapse rate of 0.57% . The relapse rate (0.84% ) in PB cases which were previously treated with DDS monotherapy a half year was significantly higher than that (0.36% ) in PB cases treated with MDT a half year. The relapse rate (0.37% ) in MB cases which were previously treated with DDS monotherapy plus MDT also significantly higher than that (0.23% ) in MB cases which were just treated with MDT two years. The proportions of cases with gradeⅡ disabilities and positive skin smears in relapse cases were 49.9% and 69.3% , respectively. Conclusion The peak of leprosy relapses after DDS monotherapy occurred during 1959~ 1988. The relapses after MDT started at the end of 1980s and may reach its peak in the next decades.
