BACKGROUND:Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius. OBJECTIVE:To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc(R)2 VDR bone plate system. METHODS:From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc(R)2 VDR bone plate system. Preoperatively, the palmar tilt angle was-31° to-4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score. RESULTS AND CONCLUSION:(1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (<2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P<0.05);the radial inclination angle was 22° to 27° (23.18° on average) (P<0.05);the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P<0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment;the excellent and good rate was 91%. (4) Acu-Loc(R)2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc(R)2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.

OBJECTIVE: To evaluate the feasibility and image quality (IQ) of prospectively high-pitch coronary CT angiography (CCTA) with low contrast medium injection rate at 70 kVp. MATERIALS AND METHODS: One hundred and four patients with suspected coronary artery disease (body mass index < 26 kg/m², sinus rhythm and heart rate < 70 beats/min) were prospectively enrolled and randomly divided into two groups. In group A and group B, 28 mL and 40 mL of 370 mgI/mL iodinated contrast media was administrated at a flow rate of 3.5 and 5 mL/s, respectively. CT values, noise, signal-to-noise ratio, contrast-to-noise ratio (CNR) of the proximal segments of coronary arteries and subjective IQ were evaluated. RESULTS: The CT values and noise in group A were significantly lower than those in group B (434–485 Hounsfield units [HU] vs. 772–851 HU, all p < 0.001; 17.8–22.3 vs. 23.3–26.4, all p < 0.005). The CNRs of the right coronary artery and left main artery showed no statistical difference between the two groups (42.1 ± 13.8 vs. 36.8 ± 16.0, p = 0.074; 38.7 ± 10.6 vs. 38.1 ± 17.0, p = 0.819). No statistical difference was observed between the two groups in IQ scores (3.04 ± 0.75 vs. 3.0 ± 0.79, p = 0.526) and diagnostic ratio (96.1% [50/52] vs. 94.2% [49/52], p = 0.647). CONCLUSION: Prospective high-pitch CCTA at 70 kVp with 28 mL of contrast media and injection rate of 3.5 mL/s could provide diagnostic IQ for normal-weight patients with heart rate of < 70 beats/min.

Objective:To analyze the failure patterns and survival after stereotactic body radiotherapy (SBRT) in patients with T 1-2N 0M 0 non-small cell lung carcinoma (NSCLC). Methods:Clinical data of early-stage NSCLC patients who received SBRT at Zhejiang Cancer Hospital from January 2012 to September 2018 were retrospectively analyzed. The primary observed endpoint was the pattern of disease progression, which was divided into intra-field recurrence, regional lymph node recurrence and distant metastasis. Overall survival (OS) and progression-free survival (PFS) were calculated by Kaplan-Meier method. Univariate analysis was conducted by log-rank test, and multivariate analysis was performed by Cox's model.Results:A total of 147 patients with 156 lesions were included. The median follow-up time was 44.0 months (16.5-95.5 months). A total of 57 patients (38.8%) progressed: 14 patients (24.5%) had recurrence with the 1-, 3-, and 5-year local recurrence rates of 2.0%, 10.9%, and 14.3%, respectively; 36 patients (63.2%) had Distant metastasis with the 1-, 3- and 5-year distant metastasis rates of 12.2%, 22.4% and 28.6%, respectively; and 7 patients (12.3%) had recurrence complicated with distant metastasis. The 3-, 5- and 7-year OS rates were 80.5%, 64.2% and 49.9% for all patients, respectively. The median OS was 78.4 months. The 3-, 5- and 7-year PFS rates were 64.8%,49.5% and 41.5%, with a median PFS of 57.9 months (95% CI: 42.3-73.5 months). Univariate and multivariate analyses showed that biologically equivalent dose and age were the factors affecting the efficacy of SBRT (both P<0.05). Conclusion:Distant metastasis is the main failure pattern in patients with T 1-2N 0M 0 NSCLC after SBRT. High-risk population should be selected for further systematic treatment to improve the efficacy.
