Objective To investigate the current status and influencing factors of falls self-efficacy among the stroke elderly patients.Methods Totally 170 elderly stroke patients were investigated using the Modified Falls Efficacy Scale (MFES),and they were tested with Berg Balance Scale (BBS) and Time Up and Go Test (TUGT).Results The average score of falls self-efficacy was 108.There were 50.6％ elderly stroke patients assigned to the group with low falls self-efficacy.Multiple Logistic regression analysis indicated that impairments of balance and mobility,severe stroke-related disability were the independent influencing factors associated with FOF,which could explain 52.0％ of variations.Conclusions Low falls self-efficacy among the stroke elderly patients is a common complaint,nurses and physicians should focus on this problem,interventions combining exercise and education of accidental falls should be taken to improve falls self-efficacy of elderly stroke patients,and prevent falls finally.

BACKGROUND:Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations stil exist.
OBJECTIVE:To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cel transplantation for bone nonunion after fracture surgery.
METHODS:Clinical and fol ow-up data from 69 patients with bone nonunion were analyzed retrospectively. Al patients were al otted to combination (n=37) and iliac (n=32) groups, fol owed by treated with autologous iliac crest graft combined with autologous bone marrow stem cel transplantation or autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve cal us scores were detected and compared between groups.
RESULTS AND CONCLUSION:The hospitalization time did not differ significantly between groups (P>0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P<0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P<0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P<0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs.

Objective To explore the effectiveness,feasibility and suitability of the guideline for nasogastric tube feeding in adult patients.Methods Based on the Ottawa Model of Research Use as framework,we screened relevant evidence from guidelines,and developed new nasogastric tube feeding nursing procedure.Nursing knowledge,the rate of compliance to new procedure and the incidence of complications of nasogastric tube feeding were used to evaluate the clinical effects of the guideline.Results Nurses' knowledge increased significantly(P＜0.05).Nurses had a high degree of implementation of the new procedure,with the rate of over 85％.Compared with the control group,the rate of complications of nasogastric tube feeing in the experimental group was lower than that in the control group.Especially,the rates of reflux and aspiration were significantly lower(P＜0.05).Both rates of tube shedding and skin damage in the intervention group were decreased significantly(P＜0.05).Conclusion The nasal feeding nursing guideline in our clinical scenarios has its effectiveness,feasibility and suitability.

Objective:To explore whether microRNA-21-5p (miR-21-5p) has the effect of anti-apoptosis of human alveolar typeⅡ epithelial cells (ATⅡ).Methods:ATⅡ cells derived from the human were cultured in vitro and used for experiments when the cells were grown until the presence of lamellar bodies and microvilli were observed by light microscope. The cells were divided into blank control group (direct culture), hydrogen peroxide (H 2O 2) injury group (cultured with 0.5 mmol/L H 2O 2), and miR-21-5p overexpression group (using miR-21-5p with a multiplicity of infection (MOI) of 100 lentiviral overexpression vector with 0.5 mmol/L H 2O 2) and miR-21-5p empty virus control group (miR-21-5p lentiviral blank vector was co-cultured with 0.5 mmol/L H 2O 2). In each group, cell proliferation was detected by cell counting kit-8 (CCK-8) at 0, 12, 24, 36, and 48 hours of cell culture; cell apoptosis was detected by flow cytometry at 24 hours of culture. Results:① Cell proliferation activity test results: with the extension of cell culture time, the cell proliferation activity of the blank control group gradually increased, while the cell proliferation activity gradually decreased after the addition of 0.5 mmol/L H 2O 2. However, the cells proliferation activity in the miR-21-5p overexpression group decreased more slowly than that in the H 2O 2 injury group and the miR-21-5p empty virus control group, and the cell proliferation activity at 48 hours was significantly higher than the H 2O 2 injury group and the miR-21-5pempty virus control group ( A value: 0.295±0.005 vs. 0.184±0.005, 0.169±0.002, both P < 0.05). It showed that both H 2O 2 and lentivirus accelerated cell damage, while miR-21-5p could reduce cell apoptosis. ② Apoptosis rate test results: compared with the blank control group, the apoptosis rate increased significantly after adding 0.5 mmol/L H 2O 2; while the apoptosis rate of the miR-21-5p overexpression group was lower than that of the H 2O 2 injury group and miR-21-5p empty virus control group [early apoptosis rate: (14.31±0.12)% vs. (24.50±0.12)%, (23.41±0.13)%; late apoptosis rate: (8.12±0.13)% vs. (9.71±0.11)%, (10.41±0.15)%; overall apoptosis rate: (22.33±0.12)% vs. (34.21±0.10)%, (33.82±0.14)%; all P < 0.05], which further proved that miR-21-5p had anti-apoptotic effects. Conclusion:miR-21-5p has an anti-apoptotic effect on human ATⅡ.

Objective To evaluate effect of clinical study combined with short-term intensive simulation on training of hysteroscopy technology. Methods Trainees receiving training of hystero-scopy technology from the January to December 2012 in Gynecology Minimally Invasive Center, Bei-jing Gynecology and Obstetrics Hospital Affiliated to Capital Medical University were enrolled and di-vided into two groups depending on the different training modes. Twenty-four trainees in group1 par-tic-ipated in three-month hysteroscopic clinical study program. Twenty-two trainees in group2 partici-pated in three-month clinical study program including one-week short term intensive simulation. After the training, the effect was evaluated by the rating scale and the Rank sum test was used for statisti-cal analysis. P<0.05 signifies statistically significant difference. Results The operation time(P=0.03), forward planning (P=0.02), instrument handing (P=0.00) and knowledge of specific procedure (P=0.04) were improved significantly in group 2 compared with those in group 1. Conclusions The training mode of clinical study combined with the short-term intensive simulation can improve hys-teroscopy technology effectively and should be widely applied.

Objective To evaluate the clinical value of 131 Ⅰ SPECT/CT in the differentiation of indeterminate 131Ⅰ uptake on planer whole body scan (WBS) for patients with DTC after 131Ⅰ treatment. Methods Fifty-six DTC patients ( male: 19, female: 37, mean age: 45 ± 15 years, ranging from 20 to 85 years) underwent 131Ⅰ treatment. 131Ⅰ WBS was performed five days after 131 Ⅰ treatment, followed by regional 131Ⅰ SPECT/CT for the indeterminate foci with abnormal uptake on 131Ⅰ WBS. The diagnostic difference of the two imaging modalities was compared by x2 test. Results There were 288 foci with abnormal uptake on 131 Ⅰ WBS, including 108 indeterminate foci (37.5%). Subsequent 131Ⅰ SPECT/CT identified 27 foci as DTC metastases (25.0%) and 71 foci as non-metastases such as benign lesions at nose, oral cavity, salivary gland, maxillary cyst, thyroid remnant, thymus, gallbladder, gastrointestinal tract, and uterus, or non-specific uptake of body contaminations (65.7%). However, the remaining 10 foci (9.3%) remained indeterminate on 131 Ⅰ SPECT/CT imaging. The diagnostic accuracy of 131 Ⅰ SPECT/CT was significantly higher than that of 131Ⅰ WBS (x2 = 102.35, P＜0. 01). Conclusion 131Ⅰ SPECT/CT could significantly improve the diagnostic accuracy for the differentiation of indeterminate foci with abnormal uptake on 131Ⅰ WBS.

Growth patterns of trichome and contaminative bacteria in Spirulina sp. liquid culture were observed, and it was found that the number of neutral and alkalophilic bacteria was always 105～106 times of that of Spirulina sp. trichome. It would be very difficult to get real pure Spirulina sp. strain by classical methods of dilution plate, capillary and single trichome selecting methods. A great deal of contaminative bacteria was washed out by two pretreatment processes. Low speed centrifugation was designed to wash the strains which usually deposit at bottom, and filtration method was designed to treat the strains usually floating at surface. Sandwich plate and dilution plate were designed for the purification of the mobile strains and non-mobile strains, respectively. A lot of strains were purified by the above processes and pure single trichome formed pure colonies on plates.
