Comparative Study[Comparison of Recovery Phase CT Features between Mild/moderate and Severe/critical Coronavirus Disease 2019 Patients].
Objective To investigate the computed tomographc(CT)features of mild/moderate and severe/critical cases of coronavirus disease 2019(COVID-19)in the recovery phase. Methods Totally 63 discharged patients in Wuhan,China,who underwent both chest CT and reverse transcription-polymerase chain reaction(RT-PCR)from February 1 to February 29,2020,were included. With RT-PCR as a gold standard,the performance of chest CT in diagnosing COVID-19 was assessed. ⋯ Total CT score in severe/critical group was also significantly higher in severe/critical group than in mild/moderate group [11 (8,17) points vs. 7 (4,9) points; Z=3.81, P<0.001]. Conclusions The CT features in the recovery stage differ between mild/moderate and severe/critical COVID-19 patients. The lung infiltration is remarkably more severe in the latter.

Review[Applications of Artificial Intelligence in Musculoskeletal System Imaging].
Artificial intelligence (AI) represents the latest wave of computer revolution and is considered revolutionary technology in many industries including healthcare. AI has been applied in medical imaging mainly due to the improvement of computational learning,big data mining,and innovations of neural network architecture. AI can improve the efficiency and accuracy of imaging diagnosis and reduce medical cost;also,it can be used to predict the disease risk. In this article we summarize and analyze the application of AI in musculoskeletal imaging.

[Factors Contributing Successful Ultrasound-guided Radial Artery Cannulation and Its Complications When Using the Short-axis Out-of-plane Procedure].
Objective To identify the possible factors that may influence the success and the complications of ultrasound-guided out-of-plane radial arterial cannulation. Methods Multivariate Logistic regression analysis was used to analyze the clinical data of 131 patients undergoing elective surgery and ultrasound-guided out-of-plane radial artery cannulation,dynamic needle tip positioning(DNTP) technique or angular distance(AD) technique and to find out the factors associated with the one-attempt success rate,overall success rate,posterior arterial wall perforation,and local hematoma. ⋯ Conclusions During ultrasound-guided out-of-plane radial cannulation,puncture at the arterial anterior wall sites with a depth of≥3 mm can reduce the incidence of posterior arterial wall perforation and local hematoma. Compared with AD,DNTP can lower the incidence of posterior arterial wall perforation.

[Efficacy of Oxycodone Hydrochloride for Patient-controlled Intravenous Analgesia after General Surgery].
Objective To evaluate the value of oxycodone hydrochloride for postoperative pain management in patients undergoing patient-controlled intravenous analgesia(PCIA). Methods The medical records on postoperative pain management in our department from January 1 to June 30,2018,were retrospectively analyzed. Totally 136 patients were assigned into oxycodone,sufentanil,or morphine groups according to the opioid used in the PCIA. ⋯ The oxycodone group experienced less vomiting(χ 2=11.360,P=0.003)and early termination of PCIA(χ 2=7.914,P=0.019)compared with the other two groups. Conclusions Oxycodone can be used for postoperative PCIA. It can alleviate a variety of postoperative pain,with superior analgesic efficiency and safety to sufentanil and morphine.
