Effects of Digital Picture Books on Young Children Undergoing Cardiac Catheterisation and Their Family Caregivers: A Randomised Controlled Trial.

Aim: To assess the impact of digital picture books on preoperative anxiety, pain and sleep quality in young children undergoing cardiac catheterisation and the anxiety of their family caregivers.

Design: A randomised, single-blinded, two-arm, parallel-group controlled trial.

Methods: Participants are young children aged 2-7 years with congenital heart disease scheduled for cardiac catheterisation and their family caregivers.

Lung Ultrasound Score as a Predictor of Failure to Wean COVID-19 Elderly Patients off Mechanical Ventilation: A Prospective Observational Study.

Background: The lung ultrasound score was developed for rapidly assessing the extent of lung ventilation, and it can predict failure to wean various types of patients off mechanical ventilation. Whether it is also effective for COVID-19 patients is unclear.

Methods: This single-center, prospective, observational study was conducted to assess the ability of the 12-region lung ultrasound score to predict failure to wean COVID-19 patients off ventilation.

[Effect of recombinant plasmid of Helicobacter pylori ureB gene on gastric epithelial cell].

To investigate the effect of recombinant plasmid of Helicobacter pylori ureB gene on gastric epithelial cell. The full length sequence of ureB gene from NCTC11637 was amplified by PCR. The recombinant plasmid was constructed by cloning the open reading frame (ORF) of ureB into the eukaryotic expression vector pcDNA3.

[Application of digital subtraction angiography and type B ultrasonography in the evaluation of vascular injury in patients with high voltage electrical injury].

Objective: To compare the difference between digital subtraction angiography (DSA) and type B ultrasonography in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.

Methods: Nineteen patients with high voltage electrical injury of upper limbs were enrolled in the study as burn group, and another 12 healthy volunteers as controls. The endovascular membrane, vascular wall thickness, intra-vascular blood flow and endovascular thrombosis formation of ulnar and radial arteries at wound site and in regions 5, 10 and 15 cm proximal to the wounds were examined by DSA and type B ultrasonography and compared with imagings of healthy volunteers as control.

[The application of ultrasonography to estimate blood vessel injury of upper limbs sustaining electric burns].

Objective: To explore a new method in estimating extent and degree of arterial injury in upper limbs sustaining high tension electric burns.

Methods: Eighteen patients (twenty-four upper limbs) with high tension electricity injury were admitted from December 1998 to September 2002, The damaged limbs consisted of four parts: wrist wound part, 5 cm, 10 cm, 15 cm parts around wrist wound, where the radial and ulnar arteries were detected using B ultrasound and color WP Doppler examination. The changes of endangium, vessel diameter, thickness of the vessel wall and volume of blood flow were recorded respectively.

[The application of ultrasonography in the diagnosis of deep electric injury].

Objective: To explore the application of ultrasonography in the diagnosis of deep electric injury.

Methods: HP-IPHX high resolution color and pulse doppler ultrasonography was employed in the study. The hemodynamic indices were determined in the burn wound area and tissues 5 - 15 cm proximal to the wound in 12 patients with deep electric injury.
