ObjectiveTo study the factors which affect the nurses' implementation of cardiac rehabilitation. MethodsData of 134 nurses who worked or are working in cardiology ward in No.1 and No.2 hospital of China Medical University was analyzed by using descriptive and inferential statistics.ResultsThe overall barriers is at a moderate level. The types of the barriers in order of mean score were no formal rehabilitation program, lack of knowledge, lack of facility, lack of support, and lack of understanding. Conclusions In order to improve the motivation of nurses to implement cardiac rehabilitation nursing, something must be done to improve nursing practice , nursing administration, and nursing education.

AIM:To investigate the effects of estrogen on the expression of matrix metalloproteinases-2(MMP-2), tissue inhibitor of metalloproteinases-2(TIMP-2) and transforming growth factor-β1(TGF-β1) in cultured human corneal stromal cells.METHODS: Inflammatory environments of human corneal stromal cells were simulated by using 1.5ng/mL IL-1β.The cells were then treated with or without different concentrations of estrogen(0, 1×10-4, 1×10-6, 1×10-8, 1×10-10mol/L estradiol)in vitro.Cell viability was evaluated by MTT.Expression levels of MMP-2, TIMP-2 and TGF-β1 proteins were measured by enzyme-linked immunosorbent assay(ELISA).RESULTS:Estrogen did not affect the viability of human corneal stromal cells.Compared with the control group, expression levels of MMP-2 and TGF-β1 proteins in E2 treatment group significantly decreased after being treated with estrogen, while the expression level of TIMP-2 significantly increased.CONCLUSION: Estrogen could, to some extent, down-regulate the expression of MMP-2 and TGF-β1 and up-regulate the expression of TIMP-2, which might contribute to protecting human cornea.

To probe into the effect on the viscosity of distilled water natural water Nacl solution and glucose solution by He-Ne Laser. Ubbohde＇s viscosimeter was used to examine the solutions treated by different times of irradiation under the action of certain Laser power to determine its viscosity. He-Ne Laser has not an effect on the viscosity of distilled water and NaCl solution. Effect on the viscosity of the natural water by He-Ne Laser ,the irradiating times in ten minutes, the viscosity of natural water is markedly lower than that from control groups, which are significantly different(P <0.05)the irradiating times beyond ten minutes, the viscosity of natural water is markedly higher than that from control groups ,which are significantly different (P <0.05).the viscosity of the glucose solution irradiated by He-Ne Laser are lower than that from control groups, but which aren＇t significantly different (P >0.05)

OBJECTIVE To study the drug-resistant diversity of Gram-negative bacilli isolated from inpatients during recent five years.METHODS A total of 1 464 Gram-negative bacilli isolated were detected and retrospectively analyzed from 1999 to 2003.Antimicrobial susceptibility testing was performed using Kirby-Bauer method.RESULTS The resistance of Pseudomonas aeruginosa to piperacillin rised from 17.6% of 1999 to 79.2% of 2003,and that to ciprofloxacin rised from 4.3% of 1999 to 36.0% of 2003.The resistance of Escherichia coli to quinolones was above 50%,while to third-generation cephalosporins was 30-40%;the resistance of E.coli to piperacillin rised from 42.9% of 1999 to 68.9% of 2003,and that to ciprofloxacin rised from 40.0% of 1999 to 73.5% of 2003.The resistance of Acinetobacter to piperacillin rised from 31.2% of 1999 to 67.5% of 2003,and that to ceftriaxone rised from 36.0% of 1999 to 74.1% of 2003.The resistance of Serratia to ceftazidime,ceftriaxone,gentamicin,amikacin and piperacillin rised sharply.Imipenem was the most active antibiotic tested against Gram-negative bacilli.Cefoperazone/sulbactam and piperacillin/tazobactam also showed excellent activity against Gram-negative bacilli.CONCLUSIONS During recent five years,the resistance of the most common Gram-negative bacilli has increased rapidly.How to delay the resistance development of common strains become a global problem.

Objective To investigate the application and clinical significance of 24-hour multichannel intraaluminal impedance-pH (MII-pH) monitoring in gastroesophageal reflux disease (GERD).Methods Fiftythree patients with GERD were enrolled in this study according to the Montreal consensus (consulting for twice reflux a week or above) from July 2011 to June 2012.Patients were divided into erosive esophagitis (EE,n =25)group and non-erosive reflux disease (NERD,n =28) group after endoscopy and MII-pH monitoring.Fifteen healthy volunteers were recruited as the normal controls.The change of pH and MII-pH parameters were compared among the three groups and the significance of the change was investigated.Results Twenty-four-hour pH monitoring showed that all the acid reflux events in the EE and the NERD groups were significantly higher than those in the control group (P ＜ 0.05).MII-pH monitoring showed that the frequencies of total reflux,acid reflux,weakly acidic reflux and percentage of acid reflux in the GERD group were higher than in the control group (total reflux:83 (54,118) vs.62 (44,111) vs.42 (20,70),P =0.003 ; acid reflux:45 (25,79) vs.22 (11,45) vs.3(1,10),P =0.000 ;weakly acidic reflux:36(18,47) vs.43(21,82) vs.23(11,43),P =0.001 ;percentage of acid reflux:53％ (37％,81％) vs.32％ (13％,48％) vs.11％ (1％,23％),P =0.002).The frequency and percentage of acid reflux in the EE group were higher than those in the NERD group (P =0.000)The percentage of weakly acidic reflux in the NERD group was higher than in the EE group (66％ (43％,79％) vs.46％ (21％,57％),P ＜0.01).The frequencies of liquid reflux and mixed reflux in the GERD groups were higher than those in the control group (22 (12,40) vs.18 (12,26) vs.9 (4,18) ; 54 (39,79) vs.42 (25,77) vs.29(14,48) ;P ＜0.01).The frequency of gas reflux in the control group was higher than in the GERD group (86(56,207) vs.31 (14,62) vs.34 (15,119),P ＜ 0.01).The frequency and percentage of proximal reflux in the GERD group were significantly higher than in the control group (28(18,41) vs.16(12,34) vs.3 (2,9) ; 33％ (22％,49％) vs.29％ (22％,35％) vs.11％ (6％,22％),P ＜ 0.001).The percentage of symptom positive index in patients with acid reflux,non-acidic reflux and total reflux in the EE group were 36.0％ (9/25),20.0％ (5/25) and 56.0％ (14/25) respectively which were higher than in the NERD group (21.4％ (6/28),14.3％ (4/28) and 35.7％ (10/28)).Conclusion MII-pH monitoring can detect more reflux events.Acid reflux plays an important role in GERD.The detective rate of GERD will be elevated when combined with MII-pH monitoring in the diagnosis.MII-pH monitoring has a distinct advantage in diagnosing GERD.
