Clinical manifestation, lifestyle, and treatment patterns of chronic erosive gastritis: A multicenter real-world study in China.

Background: Although chronic erosive gastritis (CEG) is common, its clinical characteristics have not been fully elucidated. The lack of consensus regarding its treatment has resulted in varied treatment regimens.

Aim: To explore the clinical characteristics, treatment patterns, and short-term outcomes in CEG patients in China.

Comparison of physical electrical conductivity and acupuncture de-qi sensation between stainless steel needling and supercritical fluid-treated needling.

Background: While acupuncture has been used for thousands of years, modern technology to develop new needle materials has rarely been discussed. We aim to explore a new acupuncture needle material and compare the differences in the needling sensations between the acupuncture needle surface treated with nitrogen applied supercritical fluid (SCF-N) and conventional stainless steel needles.

Methods: This was a double-blind cohort study.

Meridian study on the response current affected by electrical pulse and acupuncture.

Acupuncture and its meridians are important components of traditional Chinese medicine, and numerous opinions have been previously expressed regarding these meridians. This study aims to explore the phenomenon of meridians from the perspective of electronic physics by studying these meridians for the response current affected by electrical pulse and acupuncture. In this study, acupuncture which applies an electrical pulse was used to research the physical properties of the meridians.

Conduction Mechanism and Improved Endurance in HfO-Based RRAM with Nitridation Treatment.

A nitridation treatment technology with a urea/ammonia complex nitrogen source improved resistive switching property in HfO-based resistive random access memory (RRAM). The nitridation treatment produced a high performance and reliable device which results in superior endurance (more than 10 cycles) and a self-compliance effect. Thus, the current conduction mechanism changed due to defect passivation by nitrogen atoms in the HfO thin film.

Comparison of endoscopic submucosal tunneling dissection and thoracoscopic enucleation for the treatment of esophageal submucosal tumors.

Background And Aims: Endoscopic submucosal tunneling dissection (ESTD) has been proved to be safe and effective for removal of esophageal submucosal tumors (SMTs) and can maintain the mucosal integrity compared with other endoscopic methods. The aim of the study was to estimate the safety and efficacy of ESTD as well as compare its efficacy with thoracoscopic enucleation for esophageal SMTs, which is used increasingly as a minimally invasive approach.

Methods: We retrospectively collected the clinical data of patients with esophageal SMTs <40 mm who underwent ESTD or thoracoscopic enucleation at Nanfang Hospital between January 2008 and August 2016.

[Evaluation of 4 culture methods of Yersinia enterocolitica].

Objective: To establish a highly efficient culture method for detecting Yersinia enterocolitica in stool samples from diarrheic patients.

Methods: Stool samples collected from 200 diarrheic patients were detected with a modified and 3 conventional methods, and the positivity rates of the bacterium were compared statistically.

Results: With the modified method, 18 positive samples for Yersinia enterocolitica were detected from 200 stool samples, while with the 3 conventional methods, only 3, 5, and 8 positive samples were identified, respectively.

[Detection of Yersinia enterocolitica in diarrhea stool by real-time PCR].

Objective: To establish a quick and accurate molecular biological method to detect the Yersinia enterocolitica in diarrhea stool as an alterative to the tedious and time-consuming culture methods.

Methods: Real-time PCR, using the primer-probe specific for the yst gene, was applied to detect the pathogenic (7 serotypes) and nonpathogenic (5 serotypes) Yersinia enterocolitica, other species of Yersinia (8 types), and other enteric bacteria (8 types). Additionally, 200 samples of diarrhea stool were examined by culture method too so as to test the consistency of these two methods.
