Objective To evaluate the preoperative sleep quality of inpatients and analyze its influencing factors.Methods A self-designed questionnaire,Pittsburgh sleep quality index(PSQI)and self-rating anxiety scale(SAS)were used to investigate the sleep quality and anxiety of 114 inpatients before operation.The two groups were compared in terms of sleep quality and anxiety.The factors influencing the sleep quality were analyzed.Results Of the 114 preoperative inpatients,72.81%(83 cases)had poor sleep quality.The PSQI scores of preoperative inpatients were significantly higher than that in the healthy individuals,but significantly lower than that in the patients with insomnia(P<0.01).The main factors affecting the quality of sleep were fear of surgery,pain and discomfort,feeling strange with the ward settings,and worry about prognosis,totally causing 89.47%of the sleep disorders. Inpatients with poor sleep quality,37.3%was found suffering from anxiety.The rate was significantly higher than that of patients with good sleep quality(P<0.01).Conclusions The incidence of poor sleep quality is relatively high among the preoperative inpatients, mainly caused by fear of surgery,pain and discomfort.In order to improve the sleep quality,it is necessary to perform psychological and comfort intervention according to the sleep status of the patients.

This study examined the cytotoxicity of a new implant material modified by microarc oxidation technique. Cells on different surfaces of the implant were evaluated 2, 4 and 6 days after treatment. The results showed that cell attachment, cell morphology, and cell proliferation were influenced by the different surface treatments, and a significant increase in the osteoblast cell activity was observed on the porous MAO-Ti coating. Our results suggest that the porous MAO-Ti surface has a better biocompatibility and electrochemical performance than pure titanium surface.

Formins are widely distributed in eukaryotes such as fungi, plants and animals. They play crucial roles in regulating the polymerization of actin, coordinating the synergistic interactions between actin and microtubules, and determining cell growth and morphology. Unlike formins from fungi and animals, plant formins have been evolved into two plant-specific types. Generally, type Ⅱ formins are believed to regulate the polarized growth of cells, and type Ⅰ formins may regulate the cell expansion and division processes. Recent studies on the function of plant formins suggest it is inappropriate to classify the function of formins purely based on their structures. This review summarizes the domain organization of formins and their corresponding functions, as well as the underpinning mechanisms. Furthermore, the unsolved or unexplored issues along with future perspectives on plant formins are proposed and discussed.
