Objective:To systematically evaluate the rehabilitation effect of Otago exercise in patients with limb dysfunction.Methods:Randomized controlled trials and quasi trials on the rehabilitation effect of Otago exercise in patients with limb dysfunction were searched through computer on PubMed, Cochrane Library, Medline, Embase, Ovid, Scopus, China National Knowledge Infrastructure, VIP, and Wanfang Data. The search period was from the establishment of the database to July 31, 2022. Two researchers independently screened article, evaluated article quality, and extracted data. Meta-analysis was conducted using RevMan 5.3 software.Results:A total of 12 articles were included, including 682 patients with limb dysfunction. Meta-analysis results showed that compared with conventional physical therapy, Otago exercise could improve fall efficacy ( MD=8.64, 95% CI: 7.08-10.20, P<0.01) and balance ability ( MD=2.90, 95% CI: 0.72 -5.08, P<0.01) of patients with limb dysfunction. Conclusions:Otago exercise can improve fall efficiency and balance ability of patients with limb dysfunction, and has a positive impact on patients' limb function rehabilitation.

Objective:To explore the effects of vitamin D (VD) on lysosome activity and calcium channel protein Mcoln-1 in hippocampus and cortex of rats after traumatic brain injury (TBI).Methods:Forty-five SD rats were randomly divided into control group (Sham group), TBI model group (TBI group) and calcitriol treatment group (Calcitriol group). TBI models were established by electronic cortical impactor in TBI group and Calcitriol group. The rats in Calcitriol group were given of calitriol (1 μg/kg) by intraperitoneal injection at 30 min, 24 h and 48 h after TBI.Western blot was used to detect the expression of Mcoln-1, LAMP-1 and cathepsin-B in hippocampus and cortex region of rats. Immunofluorescence was used to detect the co-localization of Mcoln-1 and neurons three days later. Morris water maze test was performed on the 8th, 9th and 10th day after surgery in all groups.Results:Morris water maze results showed that compared with sham group((19.54±3.54)s, (18.64±4.63)s, (17.64±5.88)s), the latency of seeking platform escape ((58.75±6.65)s, (50.64±5.56)s, (42.64±5.87)s) were significantly increased in TBI group ( t=18.042, 14.325, 10.117; all P<0.05). On the 8th, 9th and 10th day after modeling, the escape latency of Calcitriol group((44.54±3.75)s, (30.74±4.74)s, (24.43±4.75)s)were significantly lower than those of TBI group ( t=6.539, 8.909, 7.369, all P<0.05). Western blot results showed that the expression of Mcoln-1 in cortex and hippocampus of TBI group were not significantly different from those of Sham group (both P>0.05). Compared with TBI group, the expression of Mcoln-1 protein in cortex and hippocampus of rats in Calcitriol group were significantly increased ( t=18.862, 17.336, both P<0.05). Immunofluorescence showed that the expression of Mcoln-1 and NeuN (neuron marker) co-located in the cortex and hippocampus of rats in the Calcitriol group. Conclusion:VD can improve learning and memory dysfunction after TBI in rats, and its mechanism may be related to the activation of Mcoln-1 calcium channel.

Objective To investigate the turnover intention of nursing staff in a Beijing tertiary traditional Chinese medicine ( TCM ) hospital. Methods Self-designed questionnaire was used to investigate 295 nursing staff from a tertiary TCM hospital. The questionnaire included the general information of nurses, problems that nurses faced with and turnover intention. Results Nurses satisfied with current job or somewhat satisfied with current job accounted for 80%; 86% of nurses once had job burnout; and 35% of nurses had turnover intention. Influencing factors of nurses′ turnover intention contained wages, working pressure, large workload, etc. Conclusions Labor unions of hospitals and the administrative departments should be more concerned about the nurses, provide relief measures, and improve the social benefits of nurses.

Objective To investigate the perioperative nursing for patients undergoing extracranial-intracranial bypass for treatment of Moyamoya disease.Methods Twenty-eight patients with Moyamoya disease who were refractory to maximal medical therapy were recruited in our hospital from March, 2011 to December, 2012, for extracranial-intracranial bypass surgery.Results For the twenty-eight patients with Moyamoya disease, twenty-three had improved in clinical symptoms after EC-IC bypass, the incidence of TIA and cerebral hemorrhage were reduced;postoperative aphasia occurred in four cases;one patient was comatose after operation and complicated with pneumonia.Under appropriate treatment and nursing,twenty-seven patients recovered in two weeks without complications like pneumonia or Deep Venous Thrombosis ( DVT ) .The only patient with complications recovered and was discharged in three weeks under careful nursing.Conclusions For Moyamoya disease patients undergoing EC-IC bypass surgery, timely and intensively perioperative nursing care, prevention and early management of complications, are the key factors of improving clinical outcome and ensuring patient recovery.

BACKGROUND: The important pathological changes of acute respiratory distress syndrome (ARDS) is disruption of the lung alveolar-capillary membrane barrier and resultant pulmonary edema associated with a proteinaceous alveolar exudate. Bone marrow mesenchymal stem cells (BMSCs) are able to carry on dividing and renewing themselves, and can eventually develop into many other types of cells. This provides a new treatment for treating injury of lungs.OBJECTIVE: To investigate the prevention of endotoxin-induced acute lung injury in rabbit by BMSCs.DESIGN, TIME AND SETTING: The randomized controlled animal study was performed at the Central Laboratory of Tangdu Hospital from October 2007 to January 2008.MATERIALS: A total of 20 rabbits were used in this study. Two rabbits were utilized to culture BMSCs. Eighteen rabbits were randomly assigned to three groups, saline control group, acute lung injury group and cell transplantation group (n = 6). Endotoxin was purchased from Sigma, USA.METHODS: Rabbit BMSCs were isolated and cultured by the Ficoll method. At the third passage, BMSCs were harvested for use.In the acute lung injury and call transplantation groups, endotoxin was infused into the trachea to establish models of acute lung injury/ARDS. Thirty minutes following model establishment, 2 mL BMSC suspension (1 x 105) was infused into the right jugular vein in the cell transplantation group. An equal volume of saline was injected into the saline control and acute lung injury groups.MAIN OUTCOME MEASURES: Number of neutrophilic granulocyte, wet to dry weight ratio of lung tissue, protein content and pathological changes in lung tissue in bronchoalveolar lavage fluid were measured.RESULTS: The increase in wet to dry weight ratio indicated the existence of pulmonary edema. The increase in neutrophilic granulocyte number suggested severe inflammatory reaction. The increased protein content showed the damage to lung alveolar-capillary membrane barrier. Following 48 hours of transplantation, neutrophilic granulocyte number and protein content in bronchoalveolar lavage fluid was significantly decreased (P < 0.01), and wet to dry weight ratio was significantly increased (P < 0.01) in the acute lung injury group compared with the saline control group. Compared with the acute lung injury group,neutrophilic granulocyte number and protein content was significantly increased (P < 0.01), and wet to dry weight ratio was significantly diminished (P < 0.01) in bronchoalveolar lavage fluid in the call transplantation group. Hematoxylin-eosin staining suggested that pulmonary alveoli was normal in the saline control group, presented typical acute lung injury in the acute lung injury group, and the pathological changes were mild in the cell transplantation group.CONCLUSION: BMSC transplantation can significantly reduce endotoxin-induced acute lung injury.
