Objective To study the appearance of skin mucous glycoprotein in vitro on the activity of human lung cancer cells A549. Methods Used alkali extraction and DEAE-52 ion exchange chromatography and Sephadex G-100 gel chromatography purification salamander mucous glycoprotein; Salamander mucous glycoprotein inhibition of human lung cancer cells A549 was detected by MTT colorimetric method in vitro.ResuIts It showed that the total sugar content in the appearance of mucus was 4.23%, the relatively pure glycoprotein component, by SDS protein electrophoresis tests, it contained a single glycoprotein component, its molecular weight was about 30 kDa.With glycoprotein pure concentration increased from 1,10, 20,40μg/mL, the glycoprotein inhibition rate of A549 cells increased; when the glycoprotein concentration was 40 μg/mL, for 24 h action, the inhibition rate of A549 cells was up to 85.66 %, while the role of 48 h, the inhibition rate of A549 cells was up to 92.32%.Inhibition effect of mucus glycoprotein on A549 cell compared with positive control drug, had significant difference.ConcIusion Salamander mucus glycoproteins of human lung cancer cells has obvious inhibitory effect, can provide theoretical basis for the development of lung cancer drug resistance.

Objective To explore whether the inflammatory stress can increase insulin resistance in the CD36 knockout (KO) mice.Methods After the mice were fed a standard chow for 14 weeks,oral glucose tolerance test,insulin release tests,lipids metabolism,SAA,IL-6,TNF-? and hepatic mRNA and proteins expression of mTOR,S6K,IRS-1,pIRS-1,2 were measured.Results Compared with the wide-type,the CD36 KO mice un-inflamed exhibited insulin resistance,and the insulin resistance index was increased[(3.01?1.24) vs (0.81?0.12),P

Objective To analyze various state of anxiety of infertility women's access to an in vitro fertilization and embryo transfer (IVF-ET) after the treatment cycle, and the relattionship between personality trait and anxiety. Methods A total of 96 patients who received the IVF-ET treatment were surveyed by questionnaire for the day state-trait anxiety at the start of treatment cycle. The patients were investigated with the questionnaire at the day, before an hour ova harvest, waiting for ? human chorionic gonadotropin (β-HCG) at 13 days after post transplant respectively. Results (1) the mean of trait anxiety was 37.66±9.11. Three points in the survey had gradually increased (36.44±9.20, 39.37±11.27 and 40.98±12.73 respectively), the difference showed significant. (2) According to research group: a highly significant difference among the level of patients' anxiety was showed between those with high-trait anxiety value and low-trait anxiety value (P<0.05). Conclusions Nurses should pay close attention to psychological state of infertility women' s received IVF-ET and carry out measures to alleviate their psychological pressure so as to improve their treatment compliance and pregnancy success rate.

Objective To build the county level hospital nursing assistance need indicator system in Jiangxi province.Methods Literature review,qualitative research method and Delphi expert consultation method were adopted to build the county level hospital nursing assistance need indicator system.The indicator system was revised through trial test.Results Two rounds of expert consultation showed that expert authority degree coefficients were 0.79,0.83; Coordination coefficient(Kendall's W) was 0.11～0.16; content experts consistency coefficient was 0.78,reliability Cronbach's α coefficient was 0.85.Through expert advice and pre-examinaion,the county level hospital nursing assistance need indicator system was built,consisting of 3 level Ⅰ indicators,8 level Ⅱ indicators,43 level ⅠⅡ indicators,including assistance contents,assistance ways and assistance time.Conclusions This study established the county level hospital nursing assistance need indicator system with better scientific and feasible characteristics.It can provide experience and guidance for the relevance and effectiveness of the implementation of follow-up care aid work.

Objective To investigate the relationship between trace elements and rachitis in children.Methods Three hundred and twelve patients with rachitis and 297 healthy children were selected for this study.Blood zinc(Zn),iron(Fe),plasma copper(Cu),calcium(Ca),magnesium(Mg),lead(Pb) and cadmium(Cd) were assayed by atomic absorption spectrophotometer.Results The levels of Zn,Fe,Cu of rachitis in blood were significantly lower than those of healthy children,while the levels of Mg,Pb were higher.There were significant differences between 2 groups(P

Objective To evaluate the performance of fast Treponema pallidum(TP) detection in voluntary blood donors and optimize the strategy for pre-donation screening.Methods Before blood donation,the gold standard TP test strip was used to make a fast detection.After blood donation,the TP-ELISA was used to test the blood.Then,analyze the donors′ anti-TP positive rate,times and intervals of donating,false positive and negative of TP fast detection.Results From 2014 to 2015,among 73 990 donors who were tested by using fast TP detection,0.71% of them(529 donors) were positive.Among the positive donors,89.2% of them(472 donors) were first-time blood donors.35 donors′ donating intervals were more than 3 years,who accounted for 61.4% of the donors who had donated for more than once.The numbers of the false positive obtained from fast TP detection were 5 and the false negative was 15.By applying the fast TP detection before blood donation,the rate of anti-TP positive had been declined from 0.71% to 0.17%.Conclusion The rejection rate of TP positive can be significantly reduced by using fast TP detection before blood donation.The fast TP detection can be used to optimize the pre-donation screening and promote blood donation service efficiency and level,while donating times and intervals of the blood donors were also considered.

Objective:To review the research hotspots and evolution of electroencephalogram (EEG) biofeedback in attention-deficit/hyperactivity disorder (ADHD) by knowledge mapping software.Methods:Based on web of science core collection database,we searched the literature with keywords (EEG biofeedback OR neurofeedback) AND (ADHD OR attention-deficit/hyperactivity disorder) in topic and time limit set before December 31,2015.319 literature were accepted,using the CiteSpace to depict the hot keywords,cited references and countries.Results:United States of America,Germany,Netherlands were top 3 countries in publishing papers of EEG biofeedback in ADHD.Based on burst of cited references,the research evolution of EEG biofeedback in ADHD could be divided into three stages.The hotspots of EEG biofeedback in ADHD were Slow Cortical Potentials protocol and double-blind placebo-controlled study.Conclusion:Future research should focus on the mechanism of EEG biofeedback and such known protocols for individualized treatment,or be designed along the lines of learning theory.
