Objective To investigate the best exposure condition for reducing the radiation dose of the chest radiography and obtaining the good quality of images. Methods With different tube voltage (kVp), tube current & time (mAs), and focus-film distance(FFD) adopted, X-ray detecting phantom was exposed by means of automatic exposure control(AEC). The dosage absorbed in skin was detected; Spatial resolution capacity, low contrast resolution capacity and low contrast sensitive degree were tested. The space and density resolution capacity were tested. The chest image quality was appraised by the way of visual observation and the measure of film density. Results The different kVp and FFD were related to the emitting skin dose (ESD), the higher kVp and the farther FFD follows the lower ESD; the higher or lower mAs has no effect on the image resolution capacity , but it had effect on image noise. The density value and seeing effect of chest film with low dose had reached good image density and needs of diagnostics. Conclusion Under the condition of 120 kVp high voltage, FFD150cm, AEC reduced density and adjusting to the processing parameters of the CR chest images, the radiation dosage of the chest computed radiography can be reduced efficiently and the good quality of images can be obtained.

Objective To investigate the clinical effects of lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease.Methods 120 patients with nonalcoholic fatty liver disease were selected,and they were randomly divided into control group (60 patients used glutathione alone) and observation group (60 patients received lactobacillus acidophilus on the basis of control group).The clinical efficacy,liver function index,blood lipid index and the ultrasonography grading of fatty liver before and after treatment of the two groups were compared.Results The clinical total effective rates of the control group and the observation group were 76.67％,91.67％,respectively.The total effective rate of the observation group was significantly higher than that of the control group(x2 =10.52,P ＜ 0.05).The levels of AST,ALT and GGT of the observation group after treatment were significantly lower than those of the control group and before treatment [(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ±7.14) U/L vs.(49.36 ± 11.08) U/L,(45.91 ± 10.24) U/L,(90.28 ± 20.70) U/L;(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L vs.(92.90 ± 24.3) U/L,(81.11 ± 17.37) U/L,(147.27 ± 34.19) U/L,t =2.88,2.54,2.91;3.01,3.36;3.18,3.48;3.41,3.87;all P ＜0.05).The levels of TG,TC,HDL-C and LDL-C of the observation group after treatment were significantly better than those of the control group and before treatment [(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.13 ± 0.80) mmol/L,(4.64 ± 0.94) mmol/L,(1.45 ± 0.48) mmol/L,(2.97 ± 0.57) mmol/L;(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.71 ± 1.33) mmol/L,(5.42 ± 1.27) mmol/L,(1.08 ± 0.36) mmol/L,(3.49 ± 0.71) mmoL/L,t =2.43.2.13,2.55,2.07;3.02,3.41;3.11,3.65;2.81,3.30;2.87,3.15;all P ＜ 0.05).In the control group,normal in 6 cases,mild in 24 cases,moderate in 21 cases and severe in 9 cases as fatty liver degree;in the observation group,normal in 13 cases,mild in 30 cases,moderate in 13 cases and severe in 4 cases as fatty liver degree.The ultrasonography grading of fatty liver of the observation group after treatment were significantly better than those of control group and before treatment (U =3.74,5.20,all P ＜ 0.05).Conclusion Lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease can efficiently promote the recovery process of liver function,regulate blood lipid levels and is helpful to improve the imaging grading.
