Supermicroscopy and arterio-venolization for digit replantation in young children after traumatic amputation: Two case reports.

Background: To report the application of supermicroscopy combined with arterio-venolization without venous anastomosis for replantation of digits following traumatic amputation in young children.

Case Summary: In March 2016, we treated two children aged 2 years and 7 years with traumatic digit amputation, no venous anastomosis, and bilateral digital inherent arteries on the palmar side. Supermicroscopy combined with an arteriovenous technique was adopted to improve the replantation surgery.

Percutaneous fixation of neonatal humeral physeal fracture: A case report and review of the literature.

Background: Neonatal distal humeral physeal fractures are rare and difficult to diagnose. Thus, missed diagnoses and delayed healing are possible. Few studies have reported surgical treatment, because a callus may develop at the fracture site 5 d after the fracture, resulting in difficult reduction, and reduction of the limb may cause further physeal injury.

Keratin 8 limits TLR-triggered inflammatory responses through inhibiting TRAF6 polyubiquitination.

Toll-like receptors (TLRs) have critical roles in innate immunity and inflammation and the detailed mechanisms by which TLR signaling is fine tuned remain unclear. Keratin 8 (CK8) belongs to the type II keratin family and is the major compontent of the intermediate filaments of simple or single-layered epithelia. Here we report that down-regulation of CK8 in mice enhanced TLR-mediated responses, rendering mice more susceptible to lipopolysaccharide (LPS)-induced endotoxin shock and Escherichia coli-caused septic peritonitis with reduced survival, elevated levels of inflammation cytokines and more severe tissue damage.

[Active surveillance on Listeria monocytogenes in seven kinds of food in 11 provinces of China in 2001].

Objective: To carry out national active surveillance on Listeria monocytogenes in foods in China.

Methods: Four thousand and thirty-four random samples from raw meat, meat product, raw milk, vegetable, yoghurt, icecream and aquatic product were collected in 11 provinces (cities), and examined for Listeria monocytogenes according to the national standard method and confirmed by BAX system (DuPont Qualicon, Wilmington, DE).

Results: Seventy isolates four kinds of foods in seven provinces were found to have LM according to the national standard method with a total isolate rate of 1.
