Clinicopathological characteristics and prognosis of 77 cases with type 3 gastric neuroendocrine tumours.

Background: For the rarity of type 3 gastric neuroendocrine tumours (g-NETs), their clinicopathological characteristics and prognosis are not well illustrated.

Aim: To describe the clinicopathological features and outcome of type 3 g-NETs in the Chinese population.

Methods: Based on the 2019 WHO pathological classification, the clinicopathological characteristics and prognosis of patients with type 3 g-NETs in China were retrospectively analysed.

Clinicopathological features and prognostic validity of the European Neuroendocrine Tumor Society (ENETS) and American Joint Committee on Cancer (AJCC) 8th staging systems in colonic neuroendocrine neoplasms.

Purpose: This study aimed to investigate the characteristics of colonic neuroendocrine neoplasms (NENs) and to validate the prognostic value of the European Neuroendocrine Tumor Society (ENETS) and American Joint Committee on Cancer (AJCC) 8th staging systems.

Methods: A total of 167 and 1248 patients with colonic NENs from 12 medical centers across China and from the Surveillance, Epidemiology, and End Results (SEER) cancer registry in the United States, respectively, were reviewed. Patients were staged according to the ENETS and AJCC 8th staging systems.

Clinicopathological characteristics and risk factors for recurrence of well-differentiated pancreatic neuroendocrine tumors after radical surgery: a case-control study.

Background: Well-differentiated pancreatic neuroendocrine tumors (PanNETs) usually have a good prognosis; however, there are patients that experience recurrence after curative resection.

Aim: To explore recurrence-related risk factors by analyzing clinicopathological data of PanNETs after radical surgery.

Methods: Clinical and pathological data from 47 patients with well-differentiated PanNETs at China-Japan Friendship Hospital from January 2012 to March 2016 were analyzed retrospectively.

A meta-analysis of surgical decompression in the treatment of diabetic peripheral neuropathy.

Background: Over the last decade, surgical decompression procedures have been commonly used in the treatment of diabetic peripheral neuropathy (DPN). However, the effectiveness of them remains to be proved.

Methods: A comprehensive literature search of databases including PubMed-Medline, Ovid-Embase, and Cochrane Library was performed to collect the related literatures.

A compact multi-wire-layered secondary winding for Tesla transformer.

A compact multi-wire-layered (MWL) secondary winding for a Tesla transformer is put forward. The basic principle of this winding is to wind the metal wire on a polymeric base tube in a multi-layer manner. The tube is tapered and has high electrical strength and high mechanical strength.

A low-jitter self-break repetitive multi-stage gas switch.

A megavolt low-jitter self-break repetitive gas switch is developed by the use of the corona stabilization and the multi-stage structure in this paper. This switch is multi-stage, consisting of one corona stabilization stage and subsequent rimfire stages. The corona stabilization stage breakdowns first, then the subsequent rimfire stages are self-fired by the over-voltage from the closure of the corona stabilization stage.
