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.

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 relationship between β2-microglobulin and D-Dimer concentration in the pregnancy-induced hypertension patients with kidney injury.Methods The 120 cases of kidney injury pregnancy-induced hypertension patients were enrolled in our hospital from Nov 2010 to Nov 2015 (served as observation group).The levels of BUN,Scr,UA,β2-microglobulin and D-Dimer were detected.The 100 cases of healthy subjects and 120 cases of normal pregnancy women were taken as controls,respectively.Results Compared with healthy control and normal pregnancy women,the levels of BUN,Scr,UA were increased significantly in the observation group (P<0.05).The results also showed that the expression of NGAL,NLRP3,NADPH oxidase subunits,TGFβ,Smad2,Smad3,β2-microglobulin and D-Dimer were sharply increased as compared with the other two group (P<0.05).Conclusion β2-microglobulin and D-Dimer are significantly related with pregnancy-induced hypertension patients with kidney injury and they would be taken as clinical indicators for the diagnosis of this disease.

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.

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.

Objective To analyze the clinical distribution and antimicrobial resistance of Acinetobacter baumannii (A.baumannii)from a hospital,so as to guide the rational use of antimicrobial agents and provide scientific basis for the prevention and control of healthcare-associated infection(HAI).Methods Distribution and antimicrobial susceptibility testing results of A.baumannii isolated from patients between January 2011 and December 2013 were analyzed retrospectively.Results A total of 339 A.baumannii isolates were isolated within three years,291 iso-lates (85.84%)were from sputum,followed by urine (n=29,8.55%),secretion(n=12,3.54%)and blood (n=3,0.89%).The main distribution departments were intensive care unit(ICU,n=149,43.95%),department of re-spiratory medicine (n=46,13.57%),department of pediatrics (n =32,9.44%)and oncology (n =22,6.49%). The resistant rate of A.baumannii to tobramycin and imipenem were 11 .11 %-49.47%,the resistant rates to the other antimicrobial agents were relatively high;antimicrobial resistant rate of 2012 and 2013 were obviously lower than 2011 .Conclusion A.baumannii from this hospital are mainly from sputum specimens,and mainly distribute in ICU and department of respiratory medicine,antimicrobial resistant rate is high,but there is a decreasing tenden-cy in recent years.

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.

Objective To establish the methods of microbial limit test for three kinds of preparations with heavy metals, such asDingxian Pills,Pizhi Lotion andJiawei Huangqin Ointment.Methods According to Chinese Pharmacopoeia 2010, the recovery rates of bacteria, fungus and yeast treated by three preparations were detected. And the methods of testing control bacteria were also validated.Results Culture medium dilution method was proved to be applicable forDingxian Pills. Culture medium dilution method combined with pre-filtration method was proper for Pizhi Lotion. And the extraction method was adopted forJiawei Huangqin Ointment. The recovery rates of these five validation strains reached 70% by appropriate methods. And the same methods were used for validation of the control bacteria.Conclusion The methods of microbial limit test for these three different preparations were established through this study.
