Objective To understand the registration situation and epidemic characteristics of tuberculosis patients in Haizhu district of guangzhou, and to provide a basis for further prevention and treatment of tuberculosis in Haizhu district. Methods The data of tuberculosis patients registered at present address in the TB information management system of Haizhu district from 2008 to 2017 were collected, and the registration data of tuberculosis patients were analyzed using descriptive epidemiological methods and relevant statistical methods. Results From 2008 to 2017, 14 384 cases of tuberculosis patients were reported in Haizhu district. The annual reported incidence rate decreased from 105.3/100,000 in 2008 to 73.1/100,000 in 2017, showing a down ward trend (χ² = 164.973, P<0.001). The relative incidence of male and female was 2:1; all age groups had morbidity, of which 25~34 years old group had the largest number of cases, accounting for 21.61% of the total number of cases; in occupational distribution, household chores and unemployed were the most, accounting for 34.48 %, followed by other (non-fixed occupations), accounting for 17.29%, retired people, accounting for 15.12%, and school students accounting for 5.52%. In terms of regional distribution, the average annual incidence rate of each street varied greatly, with the highest being 131.23/100,000 and the lowest being 66.40/100,000. The difference is statistically significant(χ²=164.973,P<0.001). Conclusion The incidence of tuberculosis in Haizhu district of Guangzhou has been decreasing year by year, but the incidence of tuberculosis in some streets is still more than 100/100,000. Male population, 25~34 years old group and low-income population (domestic and underemployed, irregular occupation, retired population) are the main population for prevention and control. Students have a large number of cases of tuberculosis, so we need to strengthen prevention, control and screening of tuberculosis in schools.

Objective To study the application of low-dose scan of multidetector row CT(MDCT)in the chemotherapy of infiltrative tuberculosis. Methods 100 patients with infiltrative pulmonary tuberculosis who were under treatment were selected. All patients accepted conventional-dose and low-dose scan of MDCT. The image quality and treatment effect of two groups were compared. Results The image quality on lung window of two groups did not differ significantly(P＞0.05). The image quality on lung window with multiplanar reconstruction of two groups also did not differ significantly(P＞0.05). The image quality on soft-tissue window differed significantly (P<0.05). The ED, DLP and CTDIvol of the low-dose group were significantly lower than those of the conventional-dose group. Conclusion For MDCT follow-up examination of patients with infiltrative tuberculosis, the image quality on lung window with low dose is similar to the image quality with conventional dose. It may effectively reduce the exposure dose of CT examination. This cost-effective modality not may can meet the curative effect evaluation of TB, but also can improve the security of the follow-up examination of patients.
