Observation of the curative effect of 125 I treatment to non-small cell lung cancer combined obstructive pneumonia / 实用放射学杂志

Objective To observe the curative effect of pure 1 25 I treatment to non-small cell lung cancer combined obstructive pneumonia.Methods 28 cases with non-small cell lung cancer combined obstructive pneumonia were enrolled.Treatment planning system was used to calculate the dosage of tumor and make up the therapeutic plan.CT-guided radiation treatment of particle im-plantation was then conducted.Follow-up was done to evaluate the curative effect one to two months after treatment.Results The total effective rate of therapeutic evaluation was 89.3%.Clinical symptoms including chest distress,hard breathing and fever were ameliorated remarkedly.Life quality score of appetite and fatigue was also improved.White blood cell reduced significantly in blood routine examination.Conclusion There is a definite curative effect of pure 1 25 I treatment to non-small cell lung cancer combined ob-structive pneumonia.

Anatomical MRI study for rotational alignment of tibial component in total knee arthroplasty / 实用医学杂志

Objective To compare the difference between a vertical line (AA) drawn to the line connecting the inner edge of the patellar tendon with the mid-point of the ending point in the posterior cruciate ligament, tibial posterior condylar line (PC), tibial plateau anterior line (AC), the maximal mediolateral distance (MMLD) and a vertical line (BB) drawn to aligning the mid-point of ending point in the posterior cruciate ligament with the medial 1 / 3 of the patellar tendon relative to the surigical transepicondylar axis (STEA) by MRI, and to explore a reliable reference to determine tibial component rotation in total knee arthroplasty , and whether it will change in knees with varus deformity. Methods Thirty healthy volunteers (Group1) and thirty osteoarthritis patients (Group2) were enrolled in this study. The angles were measured among the five tibial rotation axes and STEA after MRI. Results The angles were (-1.48 ± 2.38)°, (6.16 ± 4.53)°, (6.45 ± 5.24)° ,(5.08 ± 4.99)° and (3.24 ± 2.68)° respectively in group 1 and (-1.88 ± 2.21)°, (-3.13 ± 4.66)°, (11.13 ± 5.72)°, (4.11 ± 4.15)° and (5.12 ± 4.87)° respectively in group 2. The angle between AA and STEA was not affected by varus deformity (P > 0.05), but the others were (P < 0.05). Conclusion The angle between AA and STEA is the smallest which is used to determine tibial component rotation in knees with varus deformity is the most reliable one.
