Objective To investigate the role of the plan-do-check-action(PDCA) cycle in the quality management of intravenous infusion devices.Methods Based on the self-controlled design and cross-sectional study, the application of intravenous infusion devices before and after the implementation of PDCA cycle was investigated and compared, and the role of PDCA cycle in intravenous infusion device was evaluated.ResultsThe patients treated with intravenous infusion of 38 departments were investigated (1 152 cases in stage P and 1 140 cases in stage C).After the application of PDCA cycle,the accuracy rate of intravenous infusion device use increased from 93.2％ to 97.4％ (χ2=13.030, P<0.001).The accuracy rate of needle indwelling (98.6％ vs.95.7％, χ2=8.894, P=0.003) and central venous catheter use (87.5％ vs.38.9％, χ2=12.963, P<0.001) significantly increased after the application of PDCA cycle.Conclusion The PDCA cycle can remarkably improve the management quality of intravenous infusion devices.

Objectives To explore the effects of follow-up health edueation of cardio-vascular patients outside hospital on their compliance with doctor's advices.Methods Eighty cardio-vagcular patients were selected and divided randomly into the control group and the follow-up group with 40 cases in each group.The patients of the control group were siren instmcfons only before leaving hospital while those of the follow-up group received follow-up health education as well as the leaving-hospitsl insuuctions.Investigations were carried out one year after follow-up health education in the two groups' compliance with doctor's advices including their thempeutic changes of lifestyle,re-admittance to hospital and mortality.Results Signitlcant differences were found between the follow-up gtonp and the control group in respect of the pationts' compliance with doctor's advices,re-admittance to hospital and mortality,P＜0.01,P＜0.05.The complialice with doctor's advices in the follow-up group Wag obviously better than that of the control group.Conclusions The follow-up health education can be an effective way for promoting the cardio-vascular patients' compliance with doctor's advice after leaving hospital.

Metabolic syndrome( MS) is a group of clinical symptoms,which is based on the pathophysiol-ogy of insulin resistance that mainly includes obesity,hyperglycemia,hypertension,dyslipidemia,nonalcoholic fatty liver disease and other components.In recent years,many studies have suggested that the occurrence of colorectal cancer( CRC) is closely related with the MS components.This article reviews the research progress on the associa-tion between the major components of MS and the pathogenesis of CRC.

On the basis of generally stereotactic radiotherapy technology,intensity modulated radiation therapy technology has been developed greatly since 1990's.This technology is to improve the radiation dose distribution in the target so that the high dose area is more conformal for the three-dimentional shape of the target and the radiation dose in the normal organs and tissue around the target decreases.The characteristic of this new technology is discussed systematically in this paper.

In most universities the usage of digital information resources are not ideal.One reason is that primary audience groups of libraries——college students rarely use these resources.So we propose some measures and proposals for university libraries to provide the service of digital information resources for university students.

[Objective] To explore the best method for sequelae neuralgia of herpes zoster.[Method] Randomly divide the said patients into groups treated with external application of Chinese drugs and sky moxibustion,make observation and comparison between them.[Result] Both got high late curative effect,however most patients in the sky moxibustion group were cured without recurrence,the pain relieving rate was high once being cured,the reduce of pain index was apparent after treatment,which was of statistical meaning compared with drug application group.[Conclusion] The sky moxibustion method combines drugs and moxibustion well and has marked advantages in treating herpes zoster,worth of promotion and application.

This paper presents the common psychological problems and the efficacy of psychological warfare in modern ages, suggesting that enough emphasis should be paid to the psychological injury caused by the war itself and by psychological warfare. The related researches in our country were also reviewed.

Objective To investigate the changes in serum levels of nitric oxide ( NO) and endothelin ( ET) in type 2 diabetes patients with vascular complications, and to analyze the relationship between these levels and risk factors.Method We selected 98 cases of type 2 diabetes patients.Based on the grouping criteria, the patients were divided into diabetic patients with vascular complications ( group A,49 cases) and those without ( group B,49 cases) .In addition, 44 age-and body mass index-matched healthy cases were selected for control(group C).Height, weight, blood pressure, duration of diabetes, fasting blood glucose, hemoglobin A1c ( HbA1c), blood lipids, and serum levels of NO and ET-1 of all the patients were recorded.Results The NO levels of the two groups with diabetes mellitus were significantly lower than in group C[(43.87 ±12.05)and (53.29 ±11.75)μmol/L versus (66.08 ±16.48)μmol/L, P<0.01], while the ET-1 levels of the two groups with diabetes mellitus were significantly higher [(100.25 ±20.34) and (77.55 ±14.84) versus (53.62 ±8.40)ng/L, P<0.01] than those of the group C.The NO levels of group A were significantly lower than in group B [(43.87 ±12.05) versus (53.29 ±11.75)μmol/L, P<0.01].Moreover, the ET-1 levels of the group A were significantly higher than in group B [(100.25 ±20.34) versus (77.55 ±14.84)ng/L, P<0.01].Between the two diabetic groups, group A showed significantly higher systolic blood pressure(SBP), diastolic blood pressure(DBP), HbA1c, and course than group B (P<0.01).Correlation analysis showed a negative correlation between SBP, DBP, fasting blood glucose, HbA1c, and NO a positive correlation between high-density lipoprotein cholesterol ( HDL-C ) and NO, a negative correlation between HDL-C and ET-1, and a positive correlation between SBP,LDL-C, uric acid, fasting blood glucose, HbA1c, and ET-1.Conclusion The serum levels of NO and ET-1 in diabetic patients are evidently abnormal.Vascular endothelium injury will become more serious in patients with complications.Therefore, the serum levels of NO and ET-1 in diabetic patients are correlated with control of blood glucose, blood pressure, and blood lipid levels.
