Novel endoscopic tangential sawing technique in treatment of giant gastric bezoars: a retrospective single-center study (with video).

Background And Aims: The current methods for treatment of giant gastric bezoars mainly include chemical dissolution, endoscopic fragmentation, and surgical removal, which often have limited curative effects or generate multiple adverse events. Therefore, there is an urgent need to find new methods to overcome such a dilemma. The aim of this study was to evaluate the safety, efficacy, and feasibility of a novel guidewire-based tangential sawing fragmentation (GTSF) technique to treat giant gastric bezoars.

Comparison of the clinical value of multi-band mucosectomy versus endoscopic mucosal resection for the treatment of patients with early-stage esophageal cancer.

The present study aimed to compare the clinical value of multi-band mucosectomy (MBM) versus endoscopic mucosal resection (EMR) for the treatment of patients with early-stage esophageal cancer. Between January 2011 and December 2012, 68 patients with early-stage esophageal cancer who underwent MBM and EMR were enrolled into the present study. The curative resection rate, duration of surgery, complications and follow-up records were retrospectively analyzed.

[Plant N status in the alpine grassland of the Qinghai-Tibet Plateau: base on the N: P stoichiometry].

Plants from different functional groups show distinct response to nitrogen (N) addition, however, the patterns and underlying mechanisms across the natural N availability gradient remain unexplored. In present studies, effects of soil N fertility on aboveground N pools and production were examined, and the N: P stoichiometry was compared among forbs, graminoids, and legumes on an alpine grassland located in northeast of Qinghai-Tibet Plateau. Mean N: P ratios of the whole community in 2008 and 2009 were 9.

[Morphological differentiations of the gills of two Gymnocypris przewa-lskii subspecies in different habitats and their functional adaptations].

Gill morphologies of two subspecies of Gymnocypris przewalskii (Gymnocypris przewalskii przewalskii and Gymnocypris przewalskii ganzihonensis) in different habitats were analyzed under scanning electron microscope. Results indicated that G. p.

[Effects of nonylphenol exposure via placenta on early nervous reflex and locomotives of offspring in rat].

Objective: To explore the influence of nonylphenol (NP) on the neural behavioral development of filial generation rats exposed via placenta.

Methods: On the first day of the pregnancy, the SD rats were divided into four groups, and orally administered with NP at doses of 0, 50, 100 and 200 mg/kg on gestational day 9 approximately 15 respectively. The offspring rats of each groups were examined to observe the impact of NP on the early physiological, neurobehavioral development.

[Clinical observation on treatment of cerebral infarction by combined therapy of acupuncture with extremities tissue separating manipulation].

Objective: To observe the curative effect of combined treatment of extremities tissue separating manipulation (ETSM) and acupuncture on cerebral infarction (CI).

Methods: CI patients were randomly divided into 3 groups. Group A was treated with drug-therapy only, Group B was treated with drug-therapy plus acupuncture and Group C was treated with drug-therapy plus ETSM and acupuncture.
