A 48-year-old woman with a high-grade intraepithelial neoplasia of the gastric antrum was referred for ESD treatment.The difficulty of ESD is to expose the submucosa,especially in difficult sites and lesions with severe fibrosis.Adequate submucosal exposure is the most critical technology to reduce complications and improving efficiency.

Because of the risk related to anus preservation and the potential operative trauma, the patient refused surgery and was referred for ESD treatment. Here, we applied a novel entire traction method to deal with this subset of tumors.

In this work, the growth behavior of iridium (Ir) metal formed by atomic layer deposition (ALD) in anodic aluminum oxide (AAO) templates was explored deeply. It is found that the surface hydrophilicity is crucial for the nucleation of ALD Ir.

Recently, the incidence of craniocerebral injuries has increased dramatically due to the increased numbers of traffic accidents and aerial work injuries, threatening the physical and mental health of patients.
Aim: To investigate the impact of failure modes and effects analysis (FMEA)-based emergency management on craniocerebral injury treatment effectiveness.
Background: Appendectomy is the procedure of choice for the treatment of acute appendicitis. However, surgery may not be appropriate for patients with coexisting severe illness or comorbidities such as acute pancreatitis (AP). Endoscopic retrograde appendicitis treatment (ERAT) may be a novel alternative to surgery for treating such patients where existing medical therapies have failed.

To expand the chemical diversity and get large scale C-steroidal aglycones, the extracts of the roots of Cynanchum otophyllum were treated with 5% HCl in aqueous and the resulting hydrolysate was investigated. Nine new C-steroidal aglycones (1-9) namely cynotogenins A-I, along with seventeen known analogous (10-26), were isolated from the hydrolysate.

It exhibits high phenotypic and genetic heterogeneity. We explored the molecular etiology in a Chinese family with WS2.

Objective: To evaluate the genotype-phenotype correlation of branchio-otic syndrome (BOS) in a Chinese family.
Methods: The proband in this study was an 18-month-old boy with hearing loss, preauricular pit, and branchial fistula without a renal anomaly. We collected blood samples from 6 family members, including 4 who were affected by the syndrome.
Objective: To expose the spectrum and frequency of GJB2, GJB3, SLC26A4 and MT-RNR1 in northwest China and to investigate the underlying causative genes in patients without common mutations.
Methods: We analyzed the mutation screening results of GJB2, GJB3, SLC26A4 and MT-RNR1 in 398 unrelated severe-to-profound probands with bilateral, symmetrical sensorineural hearing loss. Subsequently, we selected 10 probands with a significant family history of inherited hearing loss (HL) that did not have the above four common gene mutations to perform next-generation sequencing (NGS) of 139 known deafness genes, followed by co-segregation analysis of all available family members.
