Objective To evaluate the value of percutaneous endoscopic gastrostomy (PEG) in the treatment of amyotrophic lateral sclerosis (ALS) patients with dysphagia. Method Sixty-five ALS patients underwent PEG from April 2005 to July 2010 were analysed retrospectively. Results All the 65 patients underwent PEG,and 2 patients failed because of dyspnea. Totally 63 patients were intubated successfully,the successful rate was 96.9%(63/65). The operation time was 8-17 min. Two patients had local infection.After 3 months, the body mass index was increased from (18.3 ± 1.0) kg/m2 to (19.7 ± 1.2) kg/m2(t = 15.8,P < 0.01), without peritonitis, migration of the gastrostomy tube and other complications. Conclusions PEG is a safe method with a low complication for ALS patients to get enteral nutrition. Dyspnea is the main reason of failure.

AIM:To investigate the effects and mechanisms of microRNA-25 (miRNA-25) on the proliferation of human esophageal squamous-cell carcinoma cell line TE1.METHODS: The abundance of miRNA-25 in different tis-sues was measured by RT-PCR.After silencing or over-expression of miRNA-25 with mimics or inhibitor in TE1 cells, the cell proliferation, cell cycle distribution and the expression of cyclin E1 and cyclin-dependent kinase 2 (CDK2) at mRNA and protein levels were measured by CCK-8 assay, BrdU detection, flow cytometry, RT-PCR and Western blot, respective-ly.RESULTS:miRNA-25 was prominent in esophageal mucosal tissue and highly expressed in TE1 cells (P<0.05).O-ver-expression of miRNA-25 increased TE1 cell proliferation, promoted the cell cycle progression and enhanced the en-trance of the cells into S phase (P<0.05).Inverse results were obtained after down-regulation of miRNA-25 (P<0.05). Furthermore, the expression of cyclin E1 and CDK2 at mRNA and protein levels was significantly increased after over-ex-pression of miRNA-25, but decreased after down-regulation of miRNA-25 (P<0.05).CONCLUSION: miRNA-25 en-hances cell cycle transition by increasing the expression of cyclin E1 and CDK2, thus accelerating TE1 cell proliferation. This study provides a novel mechanism by which miRNA-25 increases the proliferation of human esophageal squamous-cell carcinoma cell line TE1, suggesting that down-regulation of miRNA-25 may be a potential new therapeutic strategy for trea-ting esophageal squamous-cell carcinoma.

Objective To understand the job stressors, coping style and general self-efficacy of emergency nurses and relationship of them. Methods A cross-sectional study involving 83 emergency nurses were conducted through the Chinese Nurses′ Job Stress Sources Scale, Trait Coping Style Questionnaire, General Self-efficacy Scale. Results Job stress among nurses in emergency department was caused by heavy workloads and time distribution (2.88±0.82), issue of patient care (2.78±0.59). The score of emergency nurses′coping propensity was 3.77, indicating more use of positive coping. Negative coping scored higher than the norm (26.99±4.76 vs.21.25±7.41), the difference was significant (t=10.290, P<0.01). The average score of general self-efficacy was 2.40 ± 0.48, lower than the norm (2.86±0.52), the difference was significant (t=-8.07, P<0.01). Active coping style scores were negatively correlated with job stress (r =-0.294, P < 0.05), negative coping style scores were positively correlated with job stress (r =0.239, P<0.05). General self-efficacy and positive coping scores were positively correlated (r=0.270, P<0.05). Conclusions The job stress among emergency nurses was at high level, self-efficacy was not high, but they still have a positive behavior patterns. Nurse managers should take advantage of the positive psychological characteristics of nurses and give reasonable support and guidance, in order to enhance the confidence of nurses and promote self-efficacy, optimize coping, improve the physical and mental health in emergency nurses.

ObjectiveTo evaluate the efficacy and safety of combination therapy of tamsulosin and solifenacin for benign prostatic hyperplasia ( BPH ) with overactive bladder ( OAB ).Methods82 patients with OAB and coexisting BPH were randomly divided into tamsulosin group ( n = 38 ) and combination group ( n = 44). The ages were from 50 to 75 y ( averaged, 56.8 ± 8.6). Inclusion criteria: the mean frequency of micturition ≥8 times per day, the frequency of nocturia ≥2 times per day, voiding volume <200 ml each time; for the overactive bladder symptom score ( OA BSS), the 3 rd score > 2, total score > 3. The tamsulosin group accepted tamsulosin 0.2 mg once daily, the combination group accepted tansulouxin 0.2 mg and solifenacin 0.2 mg once daily. Both groups were maintained the corresponding therapy for 12 weeks.The international prostate symptom score (IPSS), Qmax, residual urine volume, OAB score and adverse reactions were recorded.ResultsThe values of IPSS ( 19.5 ±2.2 vs 15.6 ±2.4, P =0.027), the voiding symptom score ( 15.6 ± 2.4 vs 3.4 ± 1. 7, P = 0. 022) and Qmax ( 13.7 ± 3.8 vs 16.6 ± 4.1, P = 0. 034 )improved significantly after treatment in tamsulosin group ( P < 0. 05 ). The values of IPSS ( 19.7 ± 2.3 vs 9.7 ± 3.0, P <0. 001), the storage symptom score (13.8 ± 1.9 vs 5.6 ± 1.6, P <0. 001 ), OABSS (10.3 ±1.8 vs 5.3 ±1.3, P <0.001) and Qmax(14.1 ±4.1 vs 17.2 ±3.5, P=0.027) also improved significantly after treatment in combination group ( P < 0. 05 ). The values of IPSS ( 9.7 ± 3.0 vs 15.6 ±2.4, P < 0.001 ), the storage symptom score (5.6 ± 1.6 vs 12.0 ± 1.6, P < 0.001 ) and OABSS ( 5.3 ±1.3 vs 9.7 ± 2.7, P < 0. 001 ) improved significantly in combination group than those in tamsulosin group ( P <0.001 ). There were no difference between two groups in values of the voiding symptom score, Qmax and residual urine volume ( P > 0.05 ). The incidences of adverse reactions in tamsulosin group and combination group were 7.9% (3/38) and 20.5% (9/44) without significant difference. There was no acute urinary retention in both groups.ConclusionsIt is effective and safe for patients with BPH and OAB to accept combination therapy of tamsulosin and solifenacin.
