Randomized Controlled Trial
Ultrasound-Guided Artery Cannulation Technique Versus Palpation Technique in Adult Patients in Pre-Anesthesia Room: A Randomized Controlled Trial.
BACKGROUND The ultrasonography-guided technique is superior to the traditional palpation technique for artery cannulation. However, considering the complexity of assembling the ultrasonography machine, this technique has not been extensively used. Here, we compared the ultrasonography-guided technique with the traditional palpation technique in adult patients in the pre-anesthesia room. ⋯ There was no significant difference in the cannulation duration and the total procedure duration between the 2 groups. The rate of complications caused by cannulation in 2 groups was similar. CONCLUSIONS The ultrasonography-guided radial artery cannulation technique is more efficient for arterial cannulation in the pre-anesthesia room compared with the traditional palpation method.

Observational Study
Assessment of Optic Nerve Sheath Diameter in Patients Undergoing Epiduroscopy.
BACKGROUND Epiduroscopy is commonly used for the evaluation and treatment of low back pain. Saline with or without local anesthetic addition was used to visualize epidural space structure during this procedure. A rapid increase in epidural space pressure is transmitted into the spinal space to the optic nerve sheath. ⋯ The HV group showed greater changes from T0 to T2 and T3 than the LV group in ONSD. However, in both groups, ONSDs at T2 and T3 were significantly larger than those with the highest values at T2 compared to T0. CONCLUSIONS Ultrasonography of ONSD presents a good level of diagnostic accuracy for identifying epidural hypertension. In the clinical decision-making phase, this may help physicians to be more cautious about volume when performing epidural injections to treat this disease.

BACKGROUND The prevalence of bronchiectasis with comorbid chronic obstructive pulmonary disease (COPD) is rising, which causes extremely high risk of exacerbation and mortality. We aimed to evaluate the differences in clinicopathological manifestations, immune function, and inflammation in bronchiectasis patients with comorbid COPD vs. patients who only have COPD. MATERIAL AND METHODS Clinicopathological characteristics, including common potentially pathogenic microorganisms, lung function, immune function, and inflammation were assessed in bronchiectasis patients with comorbid COPD and in patients who only had COPD. ⋯ Furthermore, remarkable increased level of IL17 and IL-6 and decreased level of IL-10 and TGF-ß were observed in the bronchiectasis combined COPD than in pure COPD (All P<0.05). CONCLUSIONS Our findings suggest that P. aeruginosa is the main pathogen of bacterial infection in bronchiectasis patients with comorbid COPD. These patients have more serious clinical manifestations and immune imbalance, which should be considered when providing clinical treatment.

BACKGROUND Screw penetration into the hip joint is a severe complication during acetabular fracture surgery. The standard fluoroscopic views of the pelvis cannot provide adequate safety during screw insertion. The aim of this research was to determine and evaluate the accuracy of the acetabular lateral view for screw placement. ⋯ The ICC was 0.531 when the antero-posterior, iliac, and obturator oblique views were used. The ICC was remarkably increased when using a combination of the ''lateral'' view and the standard views for screw perforation of the joint. CONCLUSIONS Use of the lateral view of the acetabulum can be a complementary method to identify malpositioned screws, and it helps increase the accuracy rate of inserting screws in the treatment of posterior wall fracture.

BACKGROUND Rotator cuff injury is the most common cause of shoulder disability, and although the repair technique has improved, the rate of rotator cuff reduction after repair is still high. The fibrocartilage region, which appears to be histologically inserted, cannot be regenerated. In recent years, studies have reported that mesenchymal stem cells (MSCs) have enhanced cartilage regeneration in the tendon and bone interface after rotator cuff repair, which has become a hot topic of research. ⋯ To explore whether BMP-7/Smad5 pathway activation promotes differentiation of SMSCs into chondrocytes. RESULTS KGN can induce the selective differentiation of endogenous MSCs into chondrocytes by activating the BMP-7/Smad5 pathway, which promotes the regeneration of interfacial cartilage, and improves the quality of tendon healing of the tendon after rotator cuff repair. CONCLUSIONS This study found a new biological intervention method to promote the effect of tendon on bone healing after rotator cuff repair.
