The first example of a Sn(IV)-containing heteropolyoxoniobate KH[Cu(en)]{[Sn(OH)] (HNbO)}·2en·88HO () is built from nanoscale high-nuclearity cubic {[Sn(OH)](HNbO)} cluster and [Cu(en)] complexes. The cubic {[Sn(OH)](HNbO)} cage is composed of eight {NbO} clusters and 12 SnO octahedrons. The eight {NbO} fragments are situated at the vertices of the cubic cage, while the 12 SnO octahedrons are positioned along the edges of the cubic cage.

The {TeNbO} cluster represents the new tellurniobate structure type with a 19-nuclearity Nb cluster. It consists of two new monovacant Lindqvist {NbO} clusters, one boat-shaped {NbO} cluster and two TeO anions.

Objective: To investigate the prevalence of syphilis infection in voluntary blood donors in Foshan City, so as to provide reference for improving the infusion blood safety strategy of city.
Methods: A total of 657 382 voluntary blood donors in Foshan City from January 2008 to December 2017 were selected. The blood samples were tested for treponema pallidum.
The aim of the present study was to observe the effects of gene‑activated matrix (GAM) on autograft healing of the anterior cruciate ligament. Forty‑eight rabbits were randomly divided into groups A and B. Rabbits were used to construct models of anterior cruciate ligament reconstruction.
