Objective To understand the progress of paclitaxel carriers, to provide theoretical support for research of paclitaxel carriers and clinical use of paclitaxel.Methods To study literatures on paclitaxel carriers recently and understand the research direction of paclitaxel carriers.Subsequently, the advantages and disadvantages of various paclitaxel carriers were analyzed and summarized.Results Paclitaxel as an effective anti-tumor chemotherapy drugs, had poorly water-soluble, serious toxicity and side effects, which limited the wide application of paclitaxel to some degree.Development of liposomes, micelles, microspheres, nanoparticles and other new dosage forms had broken these restrictions, which had vital significance.Conclusion Paclitaxel carriers can improve the solubility of the drug, reduce side effects, and develop toward multi-functional and finely targeted.

Objective To explore the differences of serum free fatty acids (FFA)between the hyperlipidemia group and the healthy people with different ages and genders.Methods 912 healthy individuals of physical examination (healthy control group) and 1 061 patients with hyperlipidemia were selected and detected the serum FFA,total cholesterol,triglyceride,high density lipo-protein-cholesterol,low density lipoprotein-cholesterol,fasting plasma glucose and body mass index.The covariance analysis was used to investigate the differences in the level of serum FFA among different genders and age groups.The relationship between ser-um FFA and other serum lipids index in the patients with hyperlipidemia was analyzed by the multiple correlation analysis.Results The serum FFA level in the middle-aged females,middle-aged males and young males with hyperlipidemia was higher than that in the corresponding control groups;the serum FFA level in the young females with hyperlipidemia was lower than that in the other groups with hyperlipidemia;in the population groups with normal blood lipid,the serum FFA level in the old-age group was signifi-cantly higher than that in the middle-age and young group.Conclusion There is a difference in the serum FFA level in the hyperlip-idemia group with different ages and genders.

A sensitive method was developed for the determination of pacific ciguatoxin (P-CTX1) residue in fishes by high performance liquid chromatography coupled with electrospray tandem mass spectrometry ( HPLC-MS/MS). Homogenized samples of fish was extracted with acetone,degreased by freezing under -20℃ and filtered with filter paper. Then the supernatant was cleaned up with PSA column. Identification was achieved by electrospray ionization (ESI) in positive mode using multiple reaction monitoring. The calibration curve of P-CTX1 showed good linearity in the range of 0.5 -20μg/L with correlation coefficient of 0.9998. The limit of quantitation (LOQ) was 0. 1 mg/L( S/N = 10). The recoveries of P-CTX1 were between 82. 3% and 87. 2% (n =7) at spiked levels of 1.0 -20.0 ng/kg. The relative standard derivations( RSD) of the method were less than 7.8%.

Objective To integrate nurses' humanistic quality into professional nursing training, in order to improve humanistic quality and nursing quality. Methods Nurses with working years within 6 years in our hospital were chosen from May, 2009 to May, 2010. And through non-professional reading, specified materials reading, multimedia lectures, particularly the refining and essence of reading reports, humanities knowledge and humanistic care consciousness was melted into personal morality, words, deeds and cultivation. Investigation about satisfaction degree was carried out among patients before and after the training. Results Satisfaction degree of patients increased after training, so did the satisfaction degree of nurses to reading reports. Conclusions To integrate nurses' humanistic quality into professional nursing training can improve humanistic quality of nurses and nursing quality. Nurses' professional image will be increasingly standard, overall quality and service quality can be improved, and thought of dedicated service for patients will be consolidated.

Objective: To investigate the treatment effect of rational enteral nutrition in stress ulcer bleeding after severe brain injuries.Methods: 30 cases with severe brain injuries accompanied with stress ulcer bleeding were supported by enteral nutrition as clinical treatment group.50 cases with the same conditions were managed with traditional treatment methods as control.Results: All patients in clinical treatment group had no stress ulcer bleeding any more. The nutritional state was improved. On the other hand,the stress ulcer bleeding occurred again and again and the nutritional state was poor.Conclusion: Rational enteral nutrition can treat upper gastrointestinal stress ulcer bleeding in severe brain injuries effectively.

Objective Through performance analysis of domestic red blood cells folic acid instrument to verify its testing ability. Methods According to national committee for clinical laboratory standards(NCCLS)EP5-A2,the precision was obtained through two level quality product detection within 20 days then the intra-assay variation coefficient(CV),inter-assay CV and CV in labora-tory was calculated and compared with the precision requirement coming from the red blood cells folic acid biological variation.Ac-cording to EP6-A,the linear evaluation was investigated with method of polynomial regression.By measuring the red blood cells fo-lic acid from 20 persons who presented the total healthy people,the reference scope given by the manufacturer was verified.Results Within the group CV was less than 6.67%(1/4 of biological variation allow total error),between the group CV was less than 8.90%(1/3 of biological variation allow total error),the laboratory CV was less than 13.35%(1/2 of biological variation allow to-tal error).At medical decision level,the calculated bias and the confidence limit were smaller than the allow range of error.Both fac-tors of quadratic polynomial and cubic polynomial regression models were not statistically significant compared with zero,so detec-tion system was linear.The reference scope given by manufacturer was not suitable for the local people.Conclusion The precision, accuracy and linearity of domestic red blood cells folic acid analyzer were accord with requirements.The laboratory should establish reference interval suitable for the local population.
