Objective To design a neonatal nasogastric fixation mount to decrease the complications during nasogastric feeding and facilitate the nurse's operation.Methods The mount was composed of a base,a hose rack,a clamp,a freelyrotating roll ball and a fixation knob.Totally 90 preterm infants hospitalized from January to September 2016 were equally and randomly divided into a fixation mount group,a gravity feeding group and a control group using conventional nasogastric feeding.The incidences of the complications during feeding were recorded including emesis,abdominal distension and apnea,and questionnaire survey was carried out on the nurse's satisfaction for the fixation mount.Results The mount reduced the complications related to nasal feeding,increased the nurse's satisfaction.The fixation mount group had the complications incidence rate (30.0％) significantly lower than those of the gravity feeding group (43.3％) and the control group (53.3％).The nurse's satisfaction in the fixation mount group (93.3％) was higher than those in the gravity feeding group (80.0％) and control group (52.0％).Conclusion The nasograstric fixation mount is applicable for the preterm infants in far-infrared radiation table,warmer and infanette,and thus is worthy promoting clinically.

OBJECTIVE To explore the reason,hazard and preventive method of sharp injuries by analyzing nursing students who had sharp injuries.METHODS A retrospective study of hospital medical sharp injuries were taken among nursing students from Aug 2007 to May 2008.RESULTS There were 30 cases sharp injuries occurred in past year.Needles injuries accounted for 76.7%,and the others for 23.3%.Fifteen cases occurred in operation,and 15 cases occurred after operation.Twenty-three cases worked without gloves;86.7%injuris were on fingers.Hepatitis Bvaccine inoculation rate was 63.3% in 30 cases.CONCLUSIONS Enhancing occupational security education,improving nursing students′ sense of occupational security prevention and standardizing operation progress,can decrease sharp injuries among nursing students.

Background and purpose:Internal mammary sentinel nodes (IMSNs) lymphoscintigraphy could guide in ?-detecting and removing the IMSNs for the purpose of biopsy during the operation,which is helpful to determine the necessity of postoperative radiotherapy. However,IMSNs imaging rate remains low if using axillary lymph nodes (ALNs) lymphoscintigraphy. This study was to investigate the tracer’s properties and try to improve the IMSNs imaging rate through changing the label procedure. Methods:The boiling time of 99mTC-sulphur colloidal particles was shortened from 3~5 minutes to 2 minutes during the label procedure, then the colloidal particles’ diameter, distribution and stability were observed by Transmission Electron Microscope (TEM), then the IMSNs lymphoscintigraphy was performed. Results:This colloidal tracer’s shape and distribution remained stable for 3 hours, and 90% of the particles had a diameter of 10 nm, the particles tended to aggregate afterwards. 4 hours after labeling, the diameter of particles exceeded 100 nm. IMSNs could be clearly imaged if the tracer was freshly used (within 3 hours after labeling). Conclusion:Within 3 hours after the labeling the unfiltered colloidal tracer with modified procedure, the particle could be used and internal mammary lymph nodes could be imaged more clearly.

The serum concentration of vitamin A (VA) and B-carotene were determined in 50 healthy pregnant women in the later trimesters and parturition, their newborns and 20 non-pregnant women. In the meantime the contents of placental tissues were determined too. The results showed; 1. The serum VA content(2.17 umol/L, 62ug/dl)of pregnant women in the later trimesters was higher than that of non-pregnant women (1.37umol/L, 39ug/dl), but it decreased immediately after delivery. 2. There was no significant def-ference of the serum B-carotene concentration between the pregnant women and non-pregnant women. 3. The cord blood VA and B-carotene contents were much lower than those of maternal blood. 4. The contents of B-caro-tene in placentas were 9.6 times as much as VA. 5. The efficiency of transport of B-carotene from maternal blood to placental tissue was higher than that of VA, and lower than that from placenta to cord blood.

OCT angiography (OCTA) is a non-invasive imaging technique for detecting blood flow information of the retina and choroid.Dye injection is not needed with OCTA,which is different from fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA).OCTA is able to observe blood flow in different retinal and choroidal segmentation slab.This revolutionary breakthrough in OCTA algorithm provides more and more accurate blood flow informations in the diagnosis of ocular vessel diseases and the study on pathogenesis of some vessel-related eye diseases.However,like other biometric technology,OCTA has its limitations and shortcomings,for example,OCTA presents a smaller observational area than FFA and ICGA,and some factors affect the imaging quality and cause misdiagnosis during the examination and reading image.Fully understanding the principle of OCTA and its image features are helpful for eye doctors to better interpret the blood flow changes of retinal diseases,choroidal diseases,glaucoma and neuro-ophthalmic diseases.Ophthalmologists should correctly apply this imaging tool for a better monitoring and following up of these diseases.

Objective To explore the psychological intervention on the anxiety of patients under gastroscope examination. Methods According to the self-rating Anxiety Scale (SAS), 100 patients with anxiety disorder were randomly divided into observation group 50 cases, a control group of 50 cases, check the two groups of patients before, during and after adopt routine health education, observation group given psychological intervention at the same time, compared the two groups of patients with anxiety, check the time and satisfaction. Results After the psychological intervention, the scores of self-rating anxiety scale of observation group were significantly lower than those of control group, there were signiifcant differences (P<0.05), check time was shortened obviously, the difference was statistically signiifcant (P<0.05), satisfaction was also signiifcantly better than the control group the difference was statistically significant (P <0.05). Conclusion Psychological intervention can reduce the anxiety level of patients with gastroscope, shorten the examination time of gastroscope, increase the ability of patients to understand the disease, improve patient satisfaction.

ObjectivesTo explore the impact of high body mass index (BMI) on irritable bowel syndrome (IBS) in Chinese adolescents.MethodsThe students were randomly selected from middle school and high school. They completed the epidemiological questionnaire of IBS and had their height, body mass measured.ResultsIn total, 1173 students were recruited, including 700 middle school students and 473 high school students. The incidence of overweight/obesity was 30.52%. The incidence of overweight/obesity was not significantly different between boys (28.40%) and girls (32.65%) (P=0.114), and there was not significantly different between students from middle school (30.57%) and high school (30.44%) (P=0.963). Two hundreds and twenty-one students suffered from IBS and the incidence of IBS was 18.84% with no significant gender difference. The incidence of IBS was significantly higher in students from middle school (13.43%) than those from high school (26.85%) (P<0.001). The incidence of IBS was not statistically significant be-tween overweight/obese students (22.07%) and normal weight students (17.42%) (P=0.061). The distribution of IBS subtypes had no statistical significance between overweight/obese and normal weight students (χ2=0.91,P=0.823). ConclusionsOverweight/obesity and IBS were extremely prevalent in Chinese adolescents, but the correlation be-tween them remains to be confirmed.
