Non-coding RNAs (ncRNAs) are a class of functional RNAs that play critical roles in different diseases. NcRNAs include microRNAs, long ncRNAs, and circular RNAs. They are highly expressed in the brain and are involved in the regulation of physiological and pathophysiological processes of central nervous system (CNS) diseases. Mounting evidence indicates that ncRNAs play key roles in CNS diseases. Further elucidating the mechanisms of ncRNA underlying the process of regulating glial function that may lead to the identification of novel therapeutic targets for CNS diseases.

Klein-Levin syndrome is a chronic recurrent sleep disorder characterized by periodic excessive sleep, which can be accompanied by cognitive dysfunction, eating disorders, behavioral disorders, sensory disorders and emotional disorders, etc. During interval, individual′s daily functions are completely normal. Most of the KLS cases are sporadic. At present, only 17 familial cases of KLS have been reported abroad, while domestic reports in China are rare. We analyzed the detailed medical history, laboratory examinations, differential diagnosis, and the disease prevalence amongst family members of a patient with familial KLS, in order to provide reference for the follow-up study of familial cases of KLS.

Objective To investigate the effects of glycogen synthase kinase-3β (GSK-3β) and β-catenin signaling on the human renal proximal tubular epithelial HK-2 cell injury induced by depleted uranium(DU),and provide a new enlightenment for the development of DU antidotes.Methods H K-2 cells were exposed to different concentrations of DU for 3-24 h,then the protein expressions of kidney injury molecule 1 (KIM-1),neutrophil gelatinase-associated lipocalin (NGAL) and nuclear β-catenin were detected by immunofluorescence staining.The protein expressions of p-GSK-3 β(S9),GSK-3β and cmyc were detected by Western blot assay.HK-2 cells were transiently transfected by GSK-3β (KD) plasmid or treated by TDZD-8 to inhibit the activity of GSK-3β specifically.Other HK-2 cells were transiently transfected by β-catenin plasmid to overexpress the β-catenin protein.Results The percentages of KIM-1 and NGAL-positive cells increased with DU exposure time and concentrations from 300 and 600 μmol/L,and they were significantly higher than those of the blank control at 6-24 h of DU exposure (KIM-1-positive cells:t =11.06,18.97,30.49,P ＜0.05;t =6.79,16.02,85.45,P ＜ 0.05;NGAL-positive cells:t =11.78,11.37,34.29,P ＜0.05;t =7.34,21.63,36.84,P ＜0.05).In contrast,the ratio of p-GSK-3β (S9) to GSK-3β and percentage of nuclear β-catenin-positive cells were significantly higher than that of the blank control at 3-24 h of DU exposure (p-GSK-3β(S9)/GSK-3β:t =3.95,4.69,5.40,3.34,P ＜ 0.05;nuclear β-catenin-positive cells:t =4.61,6.52,36.64,14.93,P ＜ 0.05) with a maximum response at 9 h of DU exposure accompanied with corresponding increase of protein level of c-myc,a downstream target gene of β-catenin.Transient transfection of HK-2 cells with GSK-3β (KD) plasmid significantly inhibited the activity of GSK-3β (t =8.07,P ＜ 0.05) and reduced the DU-increased percentage of KIM-1-positive cells (t =24.77,P ＜ 0.05).Treatment cells with TDZD-8 inhibited the activity of GSK-3β and enhanced the percentage of nuclear β-catenin-positive cells,and it also significantly reduced the percentage of KIM-1-positive cells in HK-2 cells exposed to DU (t =6.25,6.73,P ＜ 0.05).Moreover,overexpression of β-catenin significantly reduced DU-induced cell injury (t =7.48,P ＜ 0.05).Conclusions GSK-3β/β-catenin signaling plays a key role in regulating the DU-induced cytotoxicity of HK-2 cells.Inhibition of GSK-3β activity and overexpression of β-catenin can protect the HK-2 cells from DU-induced damage.

Objective To explore the method of increasing the mastering rate of health knowledge of patients and effective rate of health education by nurses on the premise of shortened average length of hos-pital stay.Methods 316 patients were divided into group i (96 cases),group ii (117 cases) and group iii (103 cases).Patients in group i had no pre hospital education.Patients in group ii accepted quasicollective education on hospitalization notices.Patients in group iii accepted quasi-collective education on hospitalization notices and some general peri-operative knowledge.The mastering rate of knowledge and time cost for health education were compared between three groups.Results Compared to group i,group ii and group iii got higher mastering rate in 8 items of hospitalization notices.No difference was seen in acknowledge of general peri-operative knowledge.The education of hospitalization notices and total time was shortened.The difference between group ii and group iii was not positive.Conclusions Taking quasi-collective education on hospitalization notices improves patients' mastering level of hospitalization notices and nurses' education efficiency.

OBJECTIVE:To introduce dispensing room of PIVAS in order to promote the realization of public to PIVAS.METHODS:Dispensing room of PIVAS was introduced in respects of the establishment of dispensing room,staff and health control.RESULTS & CONCLUSIONS:The clean working environment,well-trained staff and strict health control ensure the quality of the dispensation of intravenous drugs.
