Objective To develop a sensitive,specific, simple and rapid quantitative real-time PCR (Q-PCR) assay for detection of Staphylococcus aureus with SmartCycler.Methods According to the nuc gene sequences specific to S.aureus, a pair of primers and one TaqMan probe were designed. An internal amplification control (IAC) which is a chimeric double-stranded DNA constructed from a fragment of the Listeria monocytogenes hly gene flanked by the nuc-specific target sequences was added to the reaction system. This IAC was detected using a second TaqMan probe labeled with a different fluorophore. The performance of the nuc-IAC Q-PCR was evaluated using artificially contaminated drinking water and commercial UTH whole milk samples spiked with ATCC 6538.Results The nuc-IAC assay could be used reliably for detection with a sensitivity of 5 copies of linear plasmid DNA per reaction, 10 fg of genomic DNA in 62.5% of the reactions or 50 cfu/ml S.aureus cells with 50% probability. The quantification was linear (r~2≥0.998) over a 6-log dynamic range, with a PCR efficiency over 0.967. The 5×10~2 CFU per 25 ml mimic sample of drinking water or milk could be detected by this assay consistently and quantifiably.Conclusion The nuc-IAC Q-PCR assay for S.aureus is developed. It could not only be applied for the quantitative detection of S.aureus, but also prevent the false negatives and underestimations of contamination loads due to PCR failure.

Objective To compare the consistency of immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in detecting c-erbB-2 status in breast cancer tissues. Methods A total of 50 breast cancer paraffin embedded samples were selected, of which there were 10 cases of c-erbB-2 protein expression (+), 20 cases of (++) and 20 cases of (+++). FISH was used to assess the amplification of c-erbB-2 gene, and SPSS 13.0 software was employed to analyze the difference and consistency between the two methods. Results IHC and FISH methods had a good consistency when detecting c-erbB-2 (+) and (+++) expressions in breast cancer tissues, with the coincidence rate of 89.2%. However, when IHC was used to test c-erbB-2 (++), the result of FISH was quite different, with the coincidence rate of only 35.3%. Conclusion IHC is a preliminary method to detect c-erbB-2 status in breast cancer. IHC and FISH methods have a good consistency in detecting c-erbB-2 (+) and (+++) status in breast cancer tissues. As detection of c-erbB-2 (++) with IHC has a different result from FISH, such patients should receive FISH confirmation for herceptin therapy.

Objective To understand the dynamic conditions after reaching the stage goal of elimination of iodine deficiency disorders (IDD) in Wenzhou, and to provide a scientific basis for prevention and treatment of IDD. Methods Three counties that the annual consumption rate of qualified iodized salt < 80% in 2014 and had the prevalence of endemic cretinism in history, Cangnan, Taishun and Yongjia, were selected as high risk monitoring areas. Three townships were selected in each area, and two primary schools were selected from each township, and 40 children urine samples were collected in each school (half male and half female) and the age of children were 8-10 years old. And near the location of these primary schools, we randomly selected 10 pregnant women in each village, and estimated the urinary iodine level and salt iodine concentration, respectively. The examination of thyroid by B ultrasound was performed in children by provincial professionals. Urinary iodine was determined using the arsenic cerium catalytic spectrophotometric method (GB/T 13025.7-2012). Salt iodine was determined by direct titration. Results Endemic cretinism case was not found in this survey, total goiter rate of 8-10 years old children was 2.04%(16/783). The median of urinary iodine was 116.1 and 108.2 μg/L, respectively, in 8 - 10 years old children and pregnant women. Iodized salt coverage rate was 90.48%(171/189), the intaking rate of qualified iodized salt was 84.66% (160/189). The concentration of pregnant women urinary iodine and salt iodine was positively correlated (r=0.54, P< 0.05). Conclusions Children's iodine nutrition is in the appropriate level, but pregnant women are in iodine definciency in Wenzhou City.

Objective To examine the status of self-perceived burden in patients with continuous ambulatory peritoneal dialysis and explore the relationships among social support,coping styles and self-perceived burden.Methods 103 elderly patients with peritoneal dialysis of outpatient follow-up were recruited.They were investigated using Self-Perceived Burden Scale,Social Support Rating Scale,and Simplified Coping Style Questionnaire.Results The total score of self-perceived burden was at a moderate level and the average score was (36.67±3.67).The total score of social support,the average score of positive coping and negative coping were (40.27±5.83),(1.69±0.26),(1.80±0.40),then the difference was statistically significant when compared with domestic norm (34.56±3.73),(1.78±0.52),(1.59±0.66) (P＜0.05).The analysis found that self-perceived burden was negatively correlated with positive coping styles,social support and each dimension (r =-0.239,-0.668,-0.725,-0.252,-0.647,P＜0.05).Conclusions Medical personnel should inspire elderly patients to make full use of social resources and guide them to take positive attitude to deal with dialysis event.It would help them maintain well psychological condition for a long time and reduce the self-perceived burden of patients.

This study was aimed to provide a reference for the development, registration, and clinical use of hospital traditional Chinese medicine (TCM) preparations, in order to analyze and assess their safety and risk. It also provided a reference for the technical review and supervision of hospital TCM preparations. Through collecting review materials of hospital TCM preparations from 2012 to 2014 in the Sichuan Food and Drug Administration, 21 preparations developed by clinical experiences were screened out. Analysis was made on their ingredients, preparation process and acute toxicity data. The results showed that 98 kinds of Chinese herbal medicines were contained in 21 preparations. The dosages of herbs were in compliance with theChina Pharmacopoeia2010 Edition. Preparation processes of 16 preparations were made by water extraction, grinding and other traditional techniques. The preparation processes of the remaining 5 preparations were involved with alcohol extraction or alcohol precipitation. Acute toxicity test data were obtained with experimental data in mice. Clinical usages of preparation were much lower than MTD or LD50. It was concluded that these hospital TCM preparations developed by clinical experiences were with high safety.

Objective:To evaluate the application method and effect of standardized scenario simulation teaching based on Kirkpatrick model in vocational protection education for nursing students.Methods:A historical controlled trial study was designed. Practical nursing students enrolled in 2018-2019 and 2017-2018 were selected into the experimental group ( n=203) and control group ( n=196), respectively. The experimental group adopted standardized scenario simulation teaching in the prevention and control education of needlestick injuries, and the control group adopted traditional classroom lecture. Using the Kirkpatrick model, the teaching effect of needlestick injuries protection for nursing students were compared between the 2 groups from such 4 levels as in reaction level, learning level, behavior level and results level. Results:There was no significant difference in the baseline data between the two groups in terms of age, gender, educational background and test scores of nursing professional knowledge as compared to that before practice. In reaction level: the nursing students' satisfaction of experimental group in teaching methods ( t=25.149, P<0.001) and teaching environment ( t=12.827, P<0.001) are higher than that of the control group, with statistical significance. In learning level: the test scores of needlestick injury knowledge in experimental group were significantly higher than those in control group ( t=8.221, P<0.001). In behavior level: the level of needlestick injury protection behavior in the experimental group was significantly higher than that in the control group ( t=9.250, P<0.001), and the knowledge conversion rate in the experimental group was higher than that in the control group ( t=6.054, P<0.001). In results level: the needlestick injuries incidence of experimental group was significantly lower than that of the control group ( χ2=15.815, P<0.001), the reported rate of needlestick injuries of experimental group was significantly lower than that of the control group ( χ2=14.185, P<0.001). Conclusion:The implementation of standardized scenario simulation teaching can effectively improve the effectiveness of vocational protection learning and reduce the incidence of needlestick injuries.
