High density lipoprotein cholesterol ( HDL-C) has received extensive attention because of its cardiovascular protective effects.Recent studies showed that HDL could promote reverse cholesterol transport ( RCT ) , be anti-inflammatory and antioxidant, and induce angiogenesis. Apolipoptrotein A-I (apoA-I), the most abundant protein of HDL, plays a pivotal role in the HDL mediated-functional activities.Short peptides based on the amphiphilic alpha helix structure of apoA-I have been designed and aimed at imitating the function of apoA-I.The function and metabolism of these mimetic peptides depend on their amino acids component and sequence , and have been proved to exert protection in against cardiovascular disease , infection, inflammation and oxidative damage, metabolic syndrome and tumor.Clinical trials confirmed their benefits, but high cost put them out of the practical applications..

Objective: To investigate the effects and mechanism of microscrew implant anchorage (MIA) in speeding up the closure of extraction space by one step and retraction of anterior teeth. Methods: Twenty-three patients with teeth extraction and required strong posterior anchorage were treated with MIA to close the extraction space. The extraction spaces were closed by two methods respectively. The extraction spaces were closed by the method of one step and retraction of anterior teeth(Ni-Ti spring from MIA to the hook on the wire combined with the elastic pull from MIA to cuspid) on the experiment sides and by the traditional one step method(Ni-Ti spring from MIA to the hook on the wire alone) on the control sides. Which side treated as trial side or control side was selected at random. The period of the space closing, the way and position of anterior teeth movement were observed on each side and the period of the space closing of two sides were tested by paired t test. Results: ①The average period of the spaces closing which was (6.69±1.07) months on the trial side and (9.56±1.19) months on the control side was significantly different (P<0.05).② After the closure of extraction spaces, the cuspid achived better position on the trial side than the contral side on which cuspid presented distal-lingual rotation. Conclusion: The extraction spaces can be closed in all cases by two methods respectively. Using MIA to close the extraction space by one step and retraction of anterior teeth can not only shorten the period of space closing but also achieve nice outcome by moving the cuspid in spongy bone.

A rapid method was developed for the determination of 9 organophosphorous flame retardants ( OPFRs) in textiles by ultra high performance liquid chromatography tandem electrospray ionization mass spectrometry ( UHPLC-MS/MS ) . Analytes in textile samples were extracted in a closed bottle at 50℃ with methanol by ultrasonic extraction for 30 min. And then, the extracted solution was injected after filtration and determined by UHPLC-MS/MS. Target analytes were separated by C18 column and methanol/water containing 5. 0 mmol/L NH4 COOH. The positive electrospray ionization and multiple reaction monitoring mode ( MRM) was utilized. The matrix effect (ME) could be compensated by adjusting the concentration of NH4COOH and the composition of the mobile phase after careful investigation with blank samples. An external standard calibration method was chosen to the quantitative analysis. Under the optimized conditions, method precision represent with relative standard deviations (RSDs) was 5. 2% (TOCP) -12. 5% (TRIS) for cotton, 6. 4%(TBEP)-13. 8% (TRIS) for polyester, and 6. 9% (TDCP) -14. 5% (TEPA) for wool samples. The recoveries for standard addition were in the range of 52 . 5% ( TEPA ) -116 . 4% ( TPP ) . The limits of quantification (LOQ, S/N=10) were between 1. 0 (TBP) and 10. 0 (TRIS) μg/kg.

Objective To investigate the sleep status, quality of life, activities of daily living and the serum levels of interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) in insomnia patients after meridian-collateral stroke treated by the new family rehabilitation program, a combined therapy including traditional family rehabilitalion, acupoint massage and ear point application. Methods A total of 80 cases of insomnia patients after meridian-collateral stroke were enrolled. Subjects were evenly divided into treatment group ( treated with new family rehabilitation program) and control group ( treated with traditional hospital health education and family rehabilitation). Clinical effects of the two groups were evaluated with the Pittsburgh Sleep Quality Index (PSQI), the brief version of WHO Quality of Life Assessment (WHOQOL-BREF) and activities of daily living ( ADL) . The serum levels of IL-1β and TNF-α were monitored before and after therapy and measured by enzyme-linked immunosorbent assay ( ELISA). Results ( 1) After treatment for 28 days, the scores of total PSQI, sleep time, sleep efficiency and sleep disorder incidence in the treatment group were significantly lower than those in the control group ( P<0.01) . ( 2) The scores of physiological, psychological, social relation, environmental dimensions of WHOQOL-BREF in the treatment group were significantly higher than those in the control group ( P<0.01) . ( 3) ADL scores were significantly higher in the treatment group than those in the control group (P<0.01) . (4) Serum levels of IL-1βand TNF-αwere increased in the treatment group as compared with those in the control group (P<0.01). Conclusion Compared with the traditional hospital health education, the new family rehabilitation program can effectively improve the quality of sleep, quality of life, as well as the activities of daily living. And the mechanism may be associated with the up-regulation of the serum levels of IL-1βand TNF-α, which are relevant to the sleep status.
