Objective To explore the method of comfort nursing in patients with nasogastric feeding and observe the influence on enhancement of patients satisfaction degree. Methods Case control study Was used in 162 conscious patients with nasogastric feeding.80 patients from January 2005 to January 2006 were selected as control group and given routine nursing.82 patients from February 2006 to May 2007 were named as the test group and received confort nursing.The satisfaction degree of patients, injury of nasal mucosa, shedding rate of the gastric tube and aspiration rate were investigated with self-designed discomfort questionnaires. Results The satisfaction degree in the test group Was 63.41%,which was higher than that of the control(40.00%,P<0.01).The rate of nasal mucosa injury, shedding of the gastric tube and aspiration rate were lower in the test group(1.22%,2.44%,1.22%)than those in the control group(8.75%,10.00%,7.50%,P<0.05).Conclusion The application of comfort nursing in patients with nasogastric feeding contributed to the enhancement of satisfaction degree of patients and nursing quality.

Objective To discuss the clinical efficacy of Mepilex surgical dressing in prevention of pressure sore. Methods 46 patients with high risk factors and Norton grading lower than 10 point were divided into the experimental group and the control group with 23 patients in each group. The control group was given reduction of local pressure, protection of the skin, nutritional support and other conventional measures to prevent pressure sore. Besides conventional nursing measures, the experimental group was given Mepilex to cover the bone eminence place, replaced every 7~10 days. The occurrence and development of the pressure sore was observed on the second, fourth, sixth and eighth week after admission. Results The occurrence rate of the experimental group on the sixth week was 4.55%, and the control group was 26.09%,the difference had statistical significance. The cure rate of the two groups showed no difference on the eighth week. Conclusions Application of Mepilex to treat patients with high risk of pressure sore has good effect.

Objective To calculate the biological reference of plasma amino acid on L-8900 amino acid analyzer and to provide reference for clinical diagnosis with domestic reagents replacing original reagent .Methods By testing the original standards and the same batch of plasma (50 cases) ,we compared original reagents with domestic reagents for their performance (including resolution , repeatability ,accuracy ) .We tested the plasma free amino acids of 400 cases of healthy people using the domestic reagents to estab-lish biological reference interval of plasma amino acid ,and do correlation analysis between the amino acids level and liver function . Results (1)Domestic reagents showed high accuracy in the results of 5 consecutive detection of amino acids were high peak separa-tion and high peak retention time and high peak area .(2)Statistics derived biological reference interval of 19 amino acids and 10 kinds of amino acids had significant differences .(3)Correlation analysis showed that ALT and liver function were negatively corre-lated with threonine(P<0 .05) .GLU and valine ,isoleucine ,leucine were positively correlated(P<0 .05) .CHO and negatively cor-related with isoleucine(P<0 .05) .Conclusion Domestic agents can replace the original reagents ,on the basis ,the biological refer-ence intervals of plasma amino acids have great importance to clinical diagnosis and prognosis .

Sixty patients with early diabetic nephropathy (DN) and normal blood pressure were randomly divided into telmisartan treatment and control groups.And the blood biochemical parameters,urinary albumin excretion rate (UAER),the serum levels of homocysteine (HCY) and transforming growth factor-β1 (TGF-β1) were measured at both pre- and post-treatment of 24 weeks.After treatment,the levels ofUAER,HCY [(61 ±26) vs.(98±38) mg/L,(11.70 ±2.86) vs.(14.4±2.8) μmol/L (P< 0.01 ) ]and homeostasis model of insulin resistance index,TGF-β1 [ ( 3.17 ± 0.66) vs.( 3.60 ± 0.87 ),(66 ± 14) vs.(77 ± 17 )U/L respectively (P < 0.05 )]in the telmisartan group were significantly lower than those in the control group.It indicated that telmisartan could improve the insulin sensitivity,significantly decrease the serum levels of HCY and TGF-β1,reduce UAER and exert kidney protection effects in the patients with early DN.

ObjectiveTo assess the efficacy of subglottic secretion drainage for preventing ventilatorassociated pneumonia.MethodsData of relevant randomized controlled trials (RCT) from January 1991 to June 2010 were collected,and data were split into two groups,namely draining group and non-draining group.Meta analysis of ventilator-associated pneumonia was carried out for finding the incidence and mortality in patients with mechanical ventilation using the methods recommended by the Cochrane Collaboration.ResultsSeven RCTs met the inclusion criteria and 1647 patients were enrolled.Subglottic secretion drainage reduced the incidence of ventilator-associated pneumonia ( OR =0.45,95% confidence interval [CI]:0.32 - 0.63 ),primarily by reducing early-onset pneumonia.But the mortalities of ventilator associated pneumonia were not significantly different between the two groups ( OR =1.03,95% confi dence interval [CI]:0.75 - 1.41 ).ConclusionsSubglottic secretion drainage appeared effective in preventing ventilator associated pneumonia among patients expected to require >48 hours of mechanical ventilation,but the mortality was unchanged.
