Values of Magnetic Resonance Imaging and Computed Tomography in the Diagnosis of Patients with Syndromes of Subacromial Impingement

Subacromial impingement syndrome (SIS) is defined as pressurization and impingement between the acromion, the bursa under the acromion, and the rotator cuff during the abduction and elevation of the shoulder joint, resulting in pain and a functional disturbance of elevation. It is the most common disorder of the shoulder, accounting for 44-65% of all complaints of shoulder pain during a physician’s office visit. The study was performed with the aim of valuing the magnetic resonance imaging (MRI) and computed tomography (CT) in diagnosing patients with SIS. A total of 68 patients with SIS were selected as study subjects and subjected to MRI and CT examinations. The diagnostic accuracy and sensitivity of MRI and CT were, respectively, 97.06 and 70.59% (P0.05). In conclusion, the diagnostic accuracy, sensitivity, and detection rate of acromion of MRI were higher compared with those of CT examination, and MRI is more suitable in the clinical diagnosis of SIS

A Randomized Controlled Trial of Puncturing and Bloodletting at Twelve Hand Jing Points to Treat Acute Carbon Monoxide Poisoning as Adjunct to First Aid Treatment: A Study Protocol

Background. Acute carbon monoxide poisoning (ACOP) is a significant cause of morbidity and mortality in many countries. Twelve Hand Jing Points (THJP) have been believed to be effective to treat all kinds of emergency calls in traditional Chinese medicine (TCM) for more than 3000 years. This randomized controlled trial (RCT) is designed to evaluate the effectiveness of THJP in curing acute carbon monoxide poisoning in first aid treatment. This paper reports the protocol of the trial. Methods/Design. This RCT is a multicenter, randomized, controlled study undergoing in China. The compliant patients are divided into the bloodletting group and standard of care group. With first aid treatments given to both of the groups, the bloodletting group is bleeding at THJP upon being hospitalized. Primary outcomes and secondary outcomes will be measured and compared between these two groups. Before treatment, immediately after treatment, and 30 minutes, 1 hour, and 4 hours after treatment, patients’ basic vital signs and state of consciousness were observed. Before treatment and 1 and 4 hours after treatment, carboxyhemoglobin concentration in venous blood samples was detected. Discussion. The objective of this study is to provide convincing evidence to clarify the efficacy and safety of THJP for early treatment of acute carbon monoxide poisoning
