A Promising Mortar Produced with Seawater and Sea Sand.

The aim of the study is the deep understanding of the essential reactivity of the environmentally friendly mortar by which its applicability can be justified. Created in the study was the environmentally friendly mortar, which helped relieve the increasing requirements on conventional building materials that are produced from exhausted freshwater and river sand nowadays. Seawater (SW) and sea sand (SS) collected from the Eastern Seas of China were used to produce the mortar at various ages, including 10-day, 33-day, and 91-day.

A novel gene recombinant collagen hemostatic sponge with excellent biocompatibility and hemostatic effect.

Effect and biosafety are the most noteworthy aspect of the hemostatic materials for trauma treatment. In this work, we evaluated the biocompatibility and hemostatic effect of a novel recombinant collagen hemostatic sponge according to ISO 10993. In addition, the interaction between the recombinant collagen hemostatic sponge and blood cells was observed by scanning electron microscopy, moreover, the hemostatic effect was evaluated by blood clotting assay in vitro and liver hemorrhage models in vivo.

Nicotine exerts neuroprotective effects by attenuating local inflammatory cytokine production following crush injury to rat sciatic nerves.

Recent studies have demonstrated that nicotine exhibited anti-inflammatory and neuroprotective properties by interacting with the alpha 7 nicotinic acetylcholine receptor (α7nAChR). However, the role of nicotine in regeneration during peripheral nerve injury has not been elucidated. The aim of this study was to investigate whether nicotine down-regulated production of proinflammatory cytokines and promoted peripheral nerve regeneration in rats.

MiR-128 inhibits the osteogenic differentiation in osteoporosis by down-regulating SIRT6 expression.

MicroRNAs (miRNAs) are involved in the regulation of osteogenic differentiation and chondrification The purpose of the present study was to explore the potential mechanism of miR-128 in osteoporosis (OP).: Quantitative real-time PCR (qRT-PCR) was used to determine the expression of miR-128 in femoral neck trabecular bones of OP patients (=40) and non-OP patients (=40). C2C12 cells were transfected with miR-128 mimic or inhibitor to determine the effect of miR-128 on osteoblastic differentiation of C2C12 cells.

[Observation on therapeutic effect of electroacupuncture at points Baliao and Huiyang (BL 35) on retention of urine induced by spinal cord injury].

Objective: To explore a more effective therapy for retention of urine induced by spinal cord injury.

Methods: Eighty-four cases were randomly divided into a treatment group of 46 cases and a control group of 38 cases. The treatment group were treated with electroacupuncture at Baliao and Huiyang (BL 35), and the control group with electroacupuncture at acupoints routinely selected.
