Human marrow stromal cells secrete microRNA-375-containing exosomes to regulate glioma progression.

It is well established that human marrow stromal cells (hMSCs) can directly migrate towards tumor microenvironments associated with tumor formation and intracellular communication. Gene regulatory networks in tumors may be targeted by microRNAs (miRNAs), especially those derived in exosomes from hMSCs. However, the potential functional roles of hMSCs in glioma cell growth still remain controversial.

Vitamin D deficiency in relation to the poor functional outcomes in nondiabetic patients with ischemic stroke.

To assess the hypothesis that vitamin D, reflected by 25-hydroxyvitamin D (25(OH) D) would be associated with higher risk of poor functional outcomes amongst nondiabetic stroke patients. The present study was conducted in Nanchang, China. Serum concentration of 25(OH) D and National Institutes of Health Stroke Scale (NIHSS) were measured at the time of admission.

[Template design of tissue flaps for covering auricular cage in one-stage total auricular reconstruction].

Objective: To study the template design of tissue flaps for covering auricular cage in order to acquire accurate and reliable design method.

Methods: By the theory of engineering drawing and three-dimensional measuring on CT image, three dimensional configuration of 40 auricular surfaces were expanded approximately, and the character of them was analysed for the template design.

Results: It is similar of the expanded graphs of auricular surface three dimensional configuration in healthy persons, and simplified template of tissue flaps is drawn based on the key points of the above graph.
