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 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.

BackBoard(BB)network teaching platform was established in physiology teaching in order to assist traditional teaching with modern information technologies.BB network teaching platform applied multimedia,domestic and foreign teaching resources,online test,interactive forum and problem based learning mode.Converting internet to efficient education environment will not only fully promote students'understanding and widen their thoughts,but also improve the teaching quality.Meanwhile,BB network teaching platform is featured in diversity,stereo,information and interaction.

OBJECTIVE To improve the administrative and controlling quality of hospital acquired infection(HAI),practice all kinds of works of HAI and decrease the incidence rate of it.METHODS We should strengthen leading power,perfect constitution and administration web,make project workable,intensify education of HAI,improve all medical staff administrative consciousness and whole quality of professional people of HAI,reinforce precaution and manipulation,and erect system of informational feedback.RESULTS All kinds of works of HAI were improved and medical staff administrative consciousness of HAI was enhanced through administration,and we could ensure the effects of sterilizing and killing bacteria.CONCLUSIONS We could carry out all kinds of institutions of HAI through administrative system of standard-check-reward and punish.

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.

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.
