Tumor 2001;(2):140-141
Objective To study the effects of super-selected internal iliac artery incubation in the treatment of advanced gynecological malignant tumors. Methods 36 cases of advanced gynecological malignant tumors (16 ovarian carcinoma, 13 cervical carcinoma, 3 vaginal carcinoma, 2 endometrial carcinoma, 1 choriocarcinoma and 1 leiomyosarcoma of uterus) were treated with this method for 48 times. 31 of these 48 times were embolized in bilateral iliac arteries, 13,2 and 1 cases the inferior mesenteric artery, the hepatic proper artery and the ovarian artery were embolized respectively. Results 4 cases showed complete response, 23 showed partial response, no change in 5 cases and in the rest 4 cases the disease was still in progress. The main side effects were slight gastro-intestinal reactions and embolism symptoms but no incubation complication occurred. Conclusion The super-selected artery of incubation will give high local density of chemotherapeutic drugs and low concentration in general circulation. The effects are better in cervical, endometrial and vaginal carcinomas than in ovarian carcinoma.

Objective To quantitatively evaluate the influence of fluid attenuated inversion prepared recovery (FLAIR) on apparent diffusion coefficient (ADC) and its clinical application value. Methods The data of DWI and FLAIR-DWI of 139 stroke were retrospectively reviewed. Paired t-test was used to analyze DWI (ADCCON ) and FLAIR-DWI (ADCFLAIR) values at varying time points from hyperacute to chronic stage. All of the lesions were further divided into cortex involved infarction and subcortical infarction. The ADCCON and ADCFLAIR values in the lesion sides and the contralateral sides were compared separately. Results The mean ADCCON values for lesions less than 6 hours, 7--12 hours, 13--24 hours, within 2 days, 3-4 days, 5-7 days and 8--14 days were not significantly different from those of the ADCFLAIR values(P >0.05) [ADCCON were (0.55±0.07), (0.50±0.09), (0.50±0. 13), (0.50 ± 0. 13), (0.62 ± 0. 14), ( 0. 60 ± 0. 12), (0. 72 ± 0. 20) × 10-3 mm2/s; ADCFLAIR were ( 0. 53 ± 0. 09 ), (0.49±0.06),(0.49±0.10),(0.48±0.08),(0.58±0. 14), (0.60±0.09),(0.73±0.15) × 10-3 mm2/s]. Lesions of 15 to 30 days [ (0. 95±0. 21 ) × 10-3 mm2/s and ( 1.02±0. 27) × 10-3 mm2/s for ADCFLAIR and ADCCON ] and the chronic stage ( >31 days) [ ADCFLAIR and ADCCON were (1.10 ± 0. 30) × 10-3 mm2/s and (1.36±0. 41 ) × 10-3 mm2/s respectively], had a significantly lower ADCFLAIR than those of the ADCCON (P <0. 01 ). For patients with a symptom duration of less than 14 days, the mean ADCFLAIR values of the cortex involved and subcortical lesions were all not significantly different from the mean ADCCON (P > 0. 05 ) [ ADCCON were ( 0. 55 ± 0. 16 ), ( 0. 61 ± 0. 14 ) × 10-3 mm2/s ; ADCFLAIR were (0.53±0. 14), (0.60±0. 13) × 10-3 mm2/s]. For patients with a symptom duration of longer than 14 days, the mean ADCFLAIR values of the cortex involved and subeortical lesions were all significantly lower than those of the mean ADCCON values [ ( 1.16±0. 36) × 10-3 mm2/s vs. ( 1.35±0. 48) × 10-3 mm2/s for cortex involved lesions and (0. 97±0. 19) × 10-3 mm2/s vs. ( 1.15±0. 33) × 10-3 mm2/s for subcortical lesions ] (P < 0. 01 ). The ADC values of the normal contralateral sides were significantly decreased after the fluid inversion prepared pulse was conducted [ ADCFLAIR, ( 0. 76 ± 0. 05 ) × 10-3 mm2/s and ADCCON, (0. 82 ± 0. 11 ) × 10-3 mm2/s ] ( p < 0. 01 ). Conclusions The FLAIR significantly decrease the absolute ADC values of the ischemic lesions 14 days later after the stroke onset, which may be helpful in determining individual lesion age. Meanwhile, the application of FLAIR can have a more accurate relative ADC value by reducing the free fluid partial volume effect of the normal contralateral side, and hence enhance the ability of detecting the subtle ischemic pathophysiological changes.

Objective To evaluate the modification of C_(60) on the radiation effects of ~(60)Co-γ irradiation on zebrafish.Methods The adult and embryonic zebrafish were used as model organisms to examine the potential of C_(60) to elicit oxidative stress responses on the surviving rate,hatching rate and malformation occurrence,both upon exposure to light or in the dark.Reactive oxygen species (ROS) production and DNA damage were examined as the possible underlying mechanism.Results 500 × 10~(-9) nano-C_(60) waterborne exposure could enhance the γ-irradiation effects by decreasing adult fish survival upon light exposure,which resulted in ROS and DNA damage increasing.The hatching rates were also inhibited with higher malformation,though dark exposure did not make any enhancement,except that the 5000× 10~(-9) C_(60) would inhibit larvae hatching and induced more malformation.Conclusions Waterborne nano-C_(60) exposure may enhance the radiation effects on zebrafish,ROS production and DNA damage increasing may be the underlying mechanism.

Objective To evaluate the prevalence of extraosseous findings on integrated CT images of routine SPECT/CT bone imaging and its clinical incremental values. Methods A total of 843 patients (470 males, 373 females, age range: 26-92 years) who underwent SPECT/CT bone imaging during May 2013 to December 2015 were enrolled in this retrospective study. A modified C-RADS was used to classify the extraosseous findings to E1, E2, E3 and E4. χ2 test was used for data analysis. Results The CT images in 78.6%(663/843) of patients were normal or with no additional clinical significance (E1 and E2), and those in 21.4%(180/843) of patients might need further assessment (E3 and E4). The rate of E4 extraosseous findings in patients with malignancy was higher than that in patients without malignancy: 9.5%(59/622) vs 5.0%(11/221); χ2=4.352, P<0.05. There was no significant difference of the rate between genders: 8.5%(40/470) in males vs 8.0%(30/373) in females; χ2=0.510, P>0.05. With age increasing, the prevalence of E4 finding increased and the rate was the highest in the patients over 80 years old (125%, 16/128). Seventy patients had E4 findings and chest masses and nodules were the most common, followed by the abdominal or pelvis lymph node enlargements. Conclusions Potentially important extraosseous findings are common on SPECT/CT. Systematic reviewing CT images and communicating the important unexpected findings to clinical physicians could enhance its clinical incremental values.
