Objective To describe and explore the practice of eye care in ICU,in order to make a specified training plan and guideline on eye care,and to improve the skill in eye care of ICU nurses. Methods A survey was conducted in 92 ICU nurses from 2 general hospitals in Huizhou city with non-random sampling using a self- made questionnaire to investigate their eye care of patients. Results The nursing practice of eye care in ICU was urged to be improved,there was no standard on eye care. Conclusions The knowledge of ICU nurses needs to be enhanced,and guideline on eye care is urged to be worked out,so that practice of eye care would be improved.

Objective:To study the quality standard for Herba Desmodii,and provide the scientific basis for a reasonable method of quality control. Methods:With the methods of microscopic identification,thin-layer chromatography and high performance liquid chromatography for the qualitative and quantitative determination of Herba Desmodii,the ethanol soluble extracts,moisture content and total ashes of Herba Desmodii were determined. Results:The characteristics of thin-layer chromatography were obvious;a good lineari-ty of quercetin and kaempferol was within the range of 0. 002-0. 050 μg(r=1. 000 0)and 0. 004-0. 100 μg(r=0. 999 9)with the av-erage recovery of 97.89%(RSD=0.89%,n=6)and 98.93%(RSD=1.31%,n=6),respectively. Conclusion:The method is simple,accurate and reproducible,which can effectively control the quality of Herba Desmodii.

Objective: To discuss the quality control method and index of traditional She medicine -Melastoma dodecandrum. Methods:The contents of gallic acid , ellagic acid and total flavonoids ( the total amount of quercetin and kaempferol) were deter-mined by HPLC. Water content, acid insoluble ash content, extract, heavy metals and harmful elements in 26 batches of herbs were also detected. Results:The content range of gallic acid, ellagic acid and total flavonoids was 9. 84-26. 31 mg·g-1 , 4. 13-16. 11 mg· g-1 and 1. 31-38. 28 mg · g-1 , respectively. The content range of water, acid insoluble ash and extract was 6. 70%-13. 90%, 1. 05%-6. 20% and 18. 00%-40. 80%, respectively. The content of Pb in all the samples was more than 5 ppm, the number of sam-ples with the content of Cd above ten thousand three was 7, and the content of As, Hg and Cu in all the samples was less than 1 ppm, ten thousand one and 20 ppm, respectively. Conclusion:The contents of gallic acid, ellagic acid and total flavonoids can comprehen-sively reflect the content of active ingredients in Melastoma dodecandrum. The contents of acid insoluble ash, Pb and Cd in Melastoma dodecandrum are relative high, which should be studied further to draw up reasonable limit.

Objective To evaluate the correlation of visual acuity measured using two different types of eye chart in children with amblyopia.Methods 119 cases (213 eyes) amblyopia patients were selected,including 40 cases (80 eyes) of refractive amblyopia,41 cases (58 eyes) of anisometropia amblyopia,and 38 cases (75 eyes) of strabismus amblyopia were selected.Best corrected visual acuity (BCVA) were determined using standard visual chart and visual noise dual chart and the correlation between the two visual acuity result were explored using Spearman's correlation analysis.Results The visual acuity in refractive amblyopia,anisometropia amblyopia and strabismus amblyopia determined by standard visual chart was statistically correlated with that determined by visual noise dual visual acuity chart.Conclusions The visual acuity measured by standard vision chart showed satisfactory linear relationship with that measured by visual acuity chart double among three types of amblyopia,however,the strength of correlation coefficient between different types of amblyopia were different:correlation coefficient in anisometropic amblyopia was the highest,and the coefficient in refractive amblyopia was the lowest.

In recent years,a considerable number of epidemiological investigations and animal studies have confirmed that metabolic diseases, such as obesity,type 2 diabetes mellitus and metabolic syndrome, have adverse effects on brain functions,inducing mood disorders and cognition impairment. Brain dysfunctions induced by obesity and related complications are associated with numerous central abnormalities,involving brain shrinkage and neurotrophic function impairment,brain insulin resistance, brain oxidative stress,and brain leptin resistance,as well as dysfunctioned dopamine motivation and the reward system. Moreover,these brain dysfunctions are mediated by several peripheral factors, such as triglycerides/free fatty acids,proinflammatory cytokines,and corticosterone/glucocorticoid. On the other hand,metabolic disturbances correlated with emotional-cognitive disorders are evident,but the mechanisms remain obscure. Because of the drawbacks of animal models, the majority of researches focus on the impact of mental stress on the metabolism of lipid and glucose. The interrela?tionship between metabolic diseases and brain functions has become one of the hot spots for research. In this review,we mainly discussed the potential mechanisms underlying mood disorders and cognition impairment induced by obesity and related complications.

OBJECTIVE To discuss the function of sustaining quality improvement in preventing perineum wound infection.METHODS The perineum wound infection situation in 2003 was retrospectively analyzed,and since then the measures for sustaining quality improvement were implemented.RESULTS In 2004 and in 2005 the perineum wound infection percentage and the stitch inflammation rate were obviously reduced than in 2003.The difference was statisticaly significant.CONCLUSIONS Sustaining quality improvement is an unceasing,gradually advancing and long-term process.The prevention of perineum wound infection is a long time work for obstetrics workers.To carry out strictly the aseptic technical operation,grasp skilled suture technology,choose easily absorbable suture,maintain suitable cleanliness and nursing and use the antibiotic could be effectively to prevent the perineum wound infection and the stitch inflammation occurrence.

Objective To explore the efficacy of a new elastic suspension strap orthosis, designed by the authors, in improving the motor function and walking ability of stroke patients. Methods Thirty-nine stroke pa-tients less than 1 month after stroke were recruited and divided randomly into a treatment group and a control group. The patients in the treatment group accepted walking training with the assistance of an elastic suspension strap orthosis, 5 times a week for 8 weeks, while the control group accepted the same training without the assistance of the elastic suspension strap orthosis. Results The treatment group improved significantly more than the control group with regard to its average Fugl-Meyer score, the functional ambulation categories of its members, and their walking speeds. Conclusions The elastic suspension strap orthosis could help correct abnormal gait patterns, improve walking speed, and enhance the recovery of walking ability in stroke patients.

Objective To investigate the effect of pre - washing without heparin on adequacy of hemodialysis. Methods Using self-control method, fifty hemodialysis patients received pre-washing with heparin in normal saline and normal saline. Then we tested Kt/v by online clearance monitoring and observed clotting condition of dialyzer and hemodialysis tubes. Results There were no difference of Kt/v between two methods. After hemodialysis, no clotting phenomenon was found in dialyzer. There was a little pot of coagulation in artery and vein pot, but no significant difference between two methods. Conclusions Pre-washing with normal saline alone can not only ensure the adequacy of hemodialysis, but also reduce the risk of cross infection and reduce the amount of heparin, simplify operational procedures, so it should be promoted.
