Effect of duodenal papilla morphology on biliary cannulation and complications in patients with common bile duct stones.

Background: The endoscopic appearance of the major duodenal papilla influences biliary cannulation and complications. This study aimed to investigate the role of major duodenal papillae in the endoscopic treatment of common bile duct (CBD) stones.

Methods: This retrospective study was conducted at Bishan Hospital of Chongqing Medical University between January 2018 and August 2022.

Investigation of Pipeline CO Leakage and Diffusion on Offshore Platforms Based on Numerical Simulation.

Pipeline transportation of CO is the key link to realize carbon capture, utilization, and storage. CO pipeline transportation may face the risk of leakage, which poses a great threat to the production process and personnel safety. It is of great significance to study the leakage and diffusion characteristics of CO in pipeline transportation for the safety design and personnel protection of the offshore CO storage platform.

Impact of Indacaterol/Glycopyrrolate on Pulmonary Function and St. George's Respiratory Questionnaire Score in Individuals with Stable Chronic Obstructive Pulmonary Disease.

Objective: This study aims to investigate the impact of indacaterol/glycopyrrolate on pulmonary function and St. George's Respiratory Questionnaire (SGRQ) scores in patients with stable chronic obstructive pulmonary disease (COPD).

Methods: A prospective randomized controlled trial (RCT) was conducted.

Chinese herbal bath therapy for the treatment of Atopic dermatitis in children: A meta-analysis and systematic review.

Background: To conduct a systematic review of the efficacy of Chinese herbal bath therapy on children with Atopic dermatitis.

Methods: We searched Chinese databases (CNKI, VIP, and Wanfang) and English databases (PubMed, Embase, Web of science, Cochrane library) for studies from the establishment of the database to September 2022. The included literature was randomized control studies investigating the treatment of Atopic dermatitis in children by Chinese herbal bath therapy.

A New Model for Calculation of Arrest Toughness in the Fracture Process of the Supercritical CO Pipeline.

A new model based on a decompression wave prediction model and an improved BTC model has been developed to investigate the arrest toughness in the fracture process of the supercritical CO pipeline. The comparison of the decompression wave velocity and the fracture propagation velocity was carried out to identify whether the pipe can prevent fracture propagation relying on its own toughness. If not, the minimum Charpy V-notch energy and the minimum wall thickness of steel pipes required for arrest fracture can be calculated using the improved BTC model.

Functionalization and reduction of graphene oxide with p-phenylene diamine for electrically conductive and thermally stable polystyrene composites.

A facile and efficient approach was developed to simultaneously functionalize and reduce graphene oxide (GO) with p-phenylene diamine (PPD) by simple refluxing. This was possible by the nucleophilic substitution reaction of epoxide groups of GO with amine groups of PPD aided by NH(3) solution. As a consequence, electrical conductivity of GO-PPD increased to 2.

A fluorescence "turn-on" chemodosimeter for Cu2+ in aqueous solution based on the ion promoted oxidation.

We developed a novel method for Cu(2+) detection based on the ion promoted oxidation reaction. Chemodosimeter L (weak fluorescence) can be oxidized into 3-benzothiazoly-7-N,N-diethylaminocoumarin (strong green fluorescence, coumarin 6) by Cu(2+) with high selectivity and sensitivity in HEPES (10 mM, pH = 7.4) buffer containing 50% (v/v) water-CH(3)CN solution.

Effects of fluid viscoelasticity on the performance of an axial blood pump model.

An aqueous Xanthan gum solution (XGS) was used as blood analog fluid to explore the influence of fluid viscoelasticity on the performance of an axial blood pump model. For comparison, a 39 wt% Newtonian aqueous glycerin solution (GS), the common fluid in blood pump tests, was also used as a working fluid. The experimental results showed that a higher head curve was obtained using XGS in the pump than using GS.

An experimental study of Newtonian and non-Newtonian flow dynamics in an axial blood pump model.

The head curves of a 1.5:1 new axial blood pump model were measured using five working fluids at five rotational speeds. The working fluids were water, a 39wt% aqueous glycerin solution (GS), and three aqueous xanthan gum solutions (XGSs) with different concentrations.

A novel rhodamine-benzimidazole conjugate as a highly selective turn-on fluorescent probe for Fe(3+).

In this manuscript, a novel probe RHBI based on the rhodamine-benzimidazole conjugate was designed and synthesized. RHBI showed an extreme selectivity for Fe(3+) over other metal ions such as Pb(2+), Ni(2+), Co(2+), Mn(2+), Zn(2+), Hg(2+), Cd(2+), Ag(+), Mg(2+), Ca(2+), Ba(2+), Na(+) and K(+) in acetonitrile. Upon the addition of 10 equiv.

[Effects of traditional Chinese medicine on the differentiation of mesenchymal stem cells to osteoblasts].

Objective: To investigate the effects of traditional Chinese medicine on the differentiation of mesenchymal stem cells (MSC) to osteoblasts.

Methods: Six male Beagle dogs weighed 10-15 kg each were divided into three groups, group A: medicine serum group, group B: non-medicine serum group and group C: bovine serum group. The serum of group A was obtained from the femoral artery of 2 Beagle dogs drinking equivalent dose of traditional Chinese medicine according to body surface area for 7 continuous days.
