ObjectiveTo investigate the early screening; treatment and care methods of the retinopathy (ROP) of preterm children. Methods210 premature children born in our hospital were selected to conduct eye screening,treatment and care from January to December 2009.The nursing key points were summarized. ResultsAmong 210 preterm children,15 cases occurred ROP,the rate was 7.1％.Lesions appeared to be the threshold for laser treatment in 8 patients(16 eyes),accounting for 3.8％.The ROP morbidity rate was higher in birth weight ≤ 1000 g group than that in birth weight ＞ 1000 g group,higher in gestational age ≤32-week group than that in gestational age＞ 32 weeks,higher in the inhalation oxygen concentration ≤ 96％ group than in inhalation oxygen concentration ＞ 96％ group.Significant difference existed in ROP and non-ROP preterm children. ConclusionsThe incidence of retinopathy of premature children was closely related with low gestational age,low birth weight and prolonged and high-concentration oxygen inhalation,timely screening and early intervention care should be given to them.

AIM: To investigate the mutagenicity of cadmium and zinc and the effect of zinc on the mutagenicity of cadmium. METHODS: The frequency of sister chromatid exchange (SCE) induced by cadmium, zinc and the combination of cadmium and zinc were observed in cultured human lymphocytes. RESULTS: Cadmium induced the increase in frequency of SCE in human lymphocytes from the concentration 1?10~(-8) mol/L to 1?10~(-6) mol/L, but zinc had a negative result. Zinc reduced the frequency of SCE induced by cadmium at the concentration from 1?10~(-6) mol/L to 1?10~(-4) mol/L and a relationship between dose and effect was also observed. CONCLUSION: Zinc inhibits the mutagenicity of cadmium in cultured human lymphocytes.

Objective To improve the sleep quality of patients by evaluating the effect of relaxation training in combination with listening to music on sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy. Methods 55 patients who reached the entrance standard were divided into the observation group (28 cases)and the control group(27 cases).The control group received routine nursing measures. The observation group were given relaxation training in combination with listening to music based on routine nursing measures. The sleep quality was appraised by Pittsburgh Sleep Quality Index (PSQI) and patients subjective feeling was investigated by self-designed questionnaires. Results The relaxation training in combination with listening to music ameliorated the sleep quality in the observation group compared with that of the control group(P＜0.01).Conclusion The relaxation training in combination with listening to music could improved the sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy.

Objective To evaluate the effect of relaxation training combined with listening to music on controlling the pain of patient with intracranial aneurysm before interventional therapy.Methods To determin the pain degree and subjective reception of the patients on admission and after relaxation training combined with listening to music.Results Pain degree relieved obviously after relaxation training combined with listening to music[(7.31±2.24)vs(3.76±2.12),P＜0.01];self-made questionnaire showed the positive evaluation of relaxation training combined with listening to music was 95%.Conclusion Relaxation training combined with listening to music can relieve the pain and general malaise bacause of absolute bedrest before interventional therapy.

Objective To explore the effect of the transtheoretical model of health behavior change on initial insulin injection in elderly patients with type 2 diabetes mellitus. Methods Thirty elderly patients with type 2 diabetes, receiving traditional training of insulin injection , were recruited as control group ( n = 30 ) between December 2013 and March 2014 . Another 30 elderly patients with type 2 diabetes, who received an education program based on the transtheoretical model of health behavior change for insulin injection training ( 30 minutes for each time and 4 times in total ) , were recruited as experiment group ( n=30 ) between April 2014 and July 2014. The knowledge of insulin injection and the operational skills in the two groups were compared between the two groups. Result Both the knowledge and operational skills at insulin injection in the experiment group were significantly better than those in the control group (P<0.01). Conclusion The transtheoretical model of health behavior change can be significant for improving the operational skills at insulin injection and therefore it can be effective in controling of blood sugar.

Objective To study the status and risk factors for falling down in elderly people in rural areas, and to provide evidences for preventions. Methods A total of 1 003 farmers aged 60 years old and over were surveyed to study the falls occurred during the previous 12 months before March 2001 in the elderly in a town of Laizhou City by cluster sampling method. Results The average incidence of falling down was 22.6%, 15.9% for men and 28.4% for women, respectively. The risk factors of falls included gender, age, single-living, falling history in the previous year, at least combined two kinds of chronic diseases, manifesting at least two symptoms, gait abnormalities, as well as complaining poor physical status and poorer general conditions than the previous year. Less social actions was negatively associated with the falls. Conclusions The falling in the elderly walkers results from an outcome of combination of multifactors. Since the complex pathogenesis, it should be prevented by a combination of several methods.

Objective: To investigate and analyze the performance of informed consent of self-expense medical expenses by medical staff. Methods: By using stratified random method, a sample of 480 medical records of medical insurance patients was selected from 40 wards of a third class A hospital in Zhejiang province in 2016. Combined with semi-open questionnaire, the performance of medical staff was investigated to do informed consent of self-expense medical expenses. Results: In general, the rate of informed consent was low, and only the rate of informing bed fee was over 70％. Medical staff thought that the effective performance of informed consent was affected by many factors, such as subjective and objective factors. Conclusion: There are still some problems in the performance of informed consent of self-expense medical expenses. It is necessary to take multi-party linkage and multi-measures interventions to improve the rate of informed consent.

Objective To explore the methods and effects of parents chaperone for premature infants with bronchopulmonary dysplasia(BPD)in neonatal intensive care unit(NICU).Methods Convenience sampling method was used to recruit premature infants diagnosed with BPD admitted from January 2014 to October 2016 in NICU in a tertiary hospital,and 41 premature infants were recruited and divided into the control group (n=19) and the experimental group(n=22) according to the time sequence of admission.Infants in the experimental group was accompanied by parents when diagnosed as BPD,and under the guidance of specialty nurses,parents performed daily care,observation of condition,treatment assistance,and early intervention;infants in the control group were provided traditional nursing mode,nurses performed nursing care,and parents were allowed to visit through the window for one hour each time,three times every week.Parental anxiety was compared between two groups at 1 day before discharge,and follow-up compliance and weight gain of infants were compared at 3 days,7 days,2 weeks,4 weeks after discharge.Results Parental anxiety at 1 day before discharge,and follow-up compliance and weight gain of infants in the experimental group were all better than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Parents chaperone can improve parents' ability of caring,reduce parents' anxiety and improve follow-up compliance after discharge,so as to improve quality of life of premature infants with BPD.

Objective To analyze the correlation between smoking and occurrence of intracranial artery stenosis.Methods From June 2015 to May 2016,a total of 10 711 inpatients with transient ischemic attack (TIA) or ischemic stroke from 20 basel hospitals of nationwide were enrolled using a cross-sectional study,76 patients with unknown smoking and smoking cessation years were excluded.Finally,a total of 10 635 patients were enrolled.Transcranial color coded sonography and/or transcranial Doppler were used evaluate the intracranial artery stenosis lesions.The basic risk factors for cerebrovascular disease (age,sex,smoking and smoking years,whether smoking cessation and years,hypertension,diabetes,hyperlipidemia,atrial fibrillation,and family history of stroke) were recorded.According to the different smoking years,the smoking years were divided into five groups:non-smoking,smoking time ≤10-year,11 to 20-year,21 to 30-year,and >30-year groups for trend chi square test.According to the different smoking cessation years in the smokers,the smoking cessation years were divided into four groups:non-cessation,cessation time 1 to 10-year,11 to 20-year,and >20-year groups for trend chi square test.The effects of different smoking years and different smoking cessation years on the occurrence of intracranial arterial stenosis were analyzed.Results The incidence of intracranial artery stenosis in the smokers (40.4%[1 433/3 547]) was significantly higher than that in the non-smoking patients (29.4%[2 085/7 088]).There was significant difference (χ2=128.850,P<0.01),and the incidence of cerebral infarction in the smokers (91.6%[3 250/3 547]) was significantly higher than the non-smokers (85.0%[6 027/7 088]).There was significant difference (χ2=92.328,P<0.01).Smoking was an independent risk factor for intracranial artery stenosis (OR,1.603;95%CI 1.456-1.765;P<0.01).With the increase of smoking years,the detection rate of intracranial arterial stenosis increased gradually (trend χ2=115.437,P<0.01).Whether giving up smoking had no significant effect on the incidence of intracranial artery stenosis in patients with ≥20 years of smoking (trend χ2=1.043,P=0.307).Conclusions Smoking is an independent risk factor for affecting intracranial artery stenosis;the risk of disease increases with the number of smoking years.Long-term smokers (≥20 years) cannot reduce the effect on intracranial artery stenosis,even if they give up smoking.

Objective To investigate the effect of serum lipid level on carotid artery stenosis in patients with ischemic cerebrovascular disease.Methods Using a multi-center cross-sectional study,10 711 consecutive inpatients with transient ischemic attack (TIA) or ischemic stroke diagnosed clearly in 20 stroke screening and prevention project base hospitals from June 2015 to May 2016 were enrolled.According to the results of carotid ultrasonography,1 560 patients with extracranial carotid artery stenosis rate≥50% screened were enrolled in the study.They were divided into a severe stenosis group (70%-99%) and a mild-moderate stenosis group (<70%).The distribution of total cholesterol (TC),triacylglycerol (TG),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels in both groups of carotid stenosis patients were analyzed,and the quantitative classification was based on the normal range of serum lipids.The distributions of serum lipid levels in different grades in patients of both groups were compared with the non-parameter test.Results The incidence of dyslipidemia in the severe stenosis group was higher than that in the mild and moderate stenosis group.There was no significant difference between the two groups (54.4%[319/586]vs.48.3%[470/974],P<0.05).Dyslipidemia was an independent risk factor for severe carotid artery stenosis (OR,1.27,95% CI 1.24-1.30,P<0.01).The TC and LDL-C levels in patients of the severe stenosis group were significantly higher than those in the mild-moderate stenosis group (TC:3.98[3.31,4.82]mmol/L vs.3.91[3.31,4.53]mmol/L,LDL-C:2.48[1.86,3.14]vs.2.30[1.79,2.80];all P<0.01).With the increase of TC and LDL-C levels,there was significant differences between the severe stenosis group and the mild-moderate stenosis group (all P<0.05),and the proportions of TC >5.80 mmol/L (7.3%[43/586]vs.0.4%[4/974]) and LDL-C>3.12 mmol/L (26.3%[154/586]vs.10.0%[97/974]) in patients of the severe stenosis group were higher than those in the mild-moderate stenosis group (26.3%[154/586]vs.10.0%[97/974]).Conclusion The high LDL-C and TC levels may increase the incidence of severe carotid artery stenosis or occlusion.
