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.

Objective To investigate the effect of batroxobin on the plasma levels of endothelin (ET) and calcitonin gene-related peptide(CGRP) in patients with acute cerebral infarction(ACI). Methods 60 patients with ACI were randomly divided into therapy group(n = 30) and control group(n = 30),500 ml of 5% GS plus 1.0g ramme of Troxerutin was intravenously dripped par day and ticlopidine 250mg/day in the control group. Based on the control group therapy,Batroxobin was intravenously dripped with 10U on the 1st day and 5U on the 3rd and 5th day for seven days. The plasma levels of ET and CGRP were detected pre and post treatment by radioimmunoassay. Results Plasma levels of ET and CGRP in batroxobin therapy group post treatment ( 81.25±27.38 ) ; ( 44. 13±13.30) ng/L were significantly different from those pre treatment(109. 83±38.24) ; (24. 73±13.59) ng/L (all P＜0. 01 ) ,and were also significantly different from those post treatment in the control group(98.07±30. 39) ; (37.02±12. 41 )ng/L (all P＜0. 01 ). Conclusion Batroxobin can accommodate the equilibration between ET and CGRP, and protect brain cell and blood vessel endothelial cell.

the Purpose of spermatozoon storerooms are setting up for solving the sterile problem.But some storerooms are found for commercial aim such as the spermatozoon storeroom,for celebrities or doctors'.It should not be approved of.The reasons is that it conflicts with such concepts as life equality,ethical relationship among families,and option for sterile couples.We should prohibit the establishment of the spermatozoon storeroom for the commercial purposes.

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.

Objective: To explore the attitude and its influencing factors of patients with cancer towards information disclosure.Methods: 302 patients with cancer were investigated with self-designed questionnaires.Results: The patients' attitudes towards Information Disclosure were significantly affected by the gender,marriage status,personality,duration of cancer information,hospitalization experience and funeral experience,with significant statistical differences﹝P

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.

The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.

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.
