TiO2 coated hollow fiber ( HF) was prepared by sol-gel method and characterized by X-ray powder diffraction and scanning electron microscope. The adsorption performances of the self-prepared TiO2 coated HF for interest metal ions were explored. The sample solution was extracted for 30 min at pH 8. 0 under stirring at speed of 700 r/min, then desorpted with 100μL of 1 mol/L HNO3 . On the basis of this, a method combining TiO2 coated HF micro-solid phase extraction with electrothermal vaporization-inductively coupled plasma mass spectrometry ( ICP-MS ) was developed for the determination of trace metal ions in environmental water samples. Under the optimized conditions, the limits of detection obtained by the proposed method were 0. 039, 0 . 021 , 0 . 009 and 0 . 018 ng/mL for CrⅢ, CuⅡ, CdⅡ and PbⅡ with enrichment factors of 12 . 5 , 11 . 7 , 10. 3 and 18. 6, respectively. The preparation reproducibility of self-prepared TiO2 coated HF ranged from 4. 5% to 6. 8% (n=9) in one batch, and from 7. 7% to 9. 6% (n=7) in batch-to-batch. The developed method has been validated by analyzing a certified reference material ( GSBZ50009-88 200925 ) and also applied to the analysis of CrⅢ, CuⅡ, CdⅡ and PbⅡ in East Lake water and snow water successfully. Meanwhile, TiO2 coated HF stir bar was prepared for a comparison and it was demonstrated that TiO2 coated HF displayed higher extraction efficiency and adsorption capacity for target ions.

Outpatient care services are usually the patient's first contact between the patients and the most bas-ic health care. The provision of outpatient care contributes to immediate and large gains in health status. The pay-ment method is one of the most common incentive methods applied by purchasers to guide the performance of outpa-tient care providers. This systematic review applied cochrane review method, and searched, screened, assessed and synthesized the relevant original studies. 19 studies were finally included. It was found that existing payment methods combined with P4 P interventions could probably slightly improved the health professionals' use of some tests and treat-ments ( adjusted RR median = 1 . 095 , range 1 . 01 to 1 . 17 ) , but may have led to little or no difference in patients' utilisation of health services ( adjusted RR median = 1 . 01 , range 0 . 96 to 1 . 15 ) and may have led to little or no difference in the control of blood pressure or cholesterol ( adjusted RR = 1 . 01 , range 0 . 98 to 1 . 04 ) . Pay for per-formance involves a complex design, each detail design may contain different incentive effect, therefore policy makers intend to apply pay-for-performance to guide the behavior of health providers, the design on each components of pay for performance should be analyzed in order to find more potential intervention points.

Objective To determine the effects of high-frequency jet ventilation (HFJV) on oxidative stress in patients during one-lung ventilation (OLV). Methods Forty-five patients undergoing elective radical esophageal cancer resection were divided into three groups with 15 cases each by random digits table: two lung ventilation group ( group A), OLV group (group B), HFJV- OLV group ( group C, working pressure 1 kg/cm2 and frequency 100 times/min). Venous blood samples were taken before induction (T0),at30min (T1),90min (T2),150min (T3) after OLV and the end of operation (T4) for measuring serum superoxide dismutase(SOD),malondialdehyde (MDA) and nitric oxide (NO). Results SOD was lower at T2-T4 in group B[(47 ± 10), (37 ±9), (41 ±7) kU/L] and group C[(58 ± 12), (51 ± 11), (49 ± 9) kU/L] than those in group A [(78 ±8), (75 ±7), (79 ±6) kU/L](P＜ 0.05),and MDA and NO were lower at T1-T4 in group B and group C than that in group A(P＜ 0.05). SOD was higher at T3 in group C than that in group B (P ＜ 0.05), MDA at T1-T4 and NO at T2-T4 were lower in group C than those in group B (P ＜ 0.05). Conclusion HFJV can effectively decrease oxidative stress in patients during OLV.

ving CQI(P＜0.05).Conclusion CQI program effectively reduces CRBSI incidenee in cancer patients with PICC.

In this study, real-time PCR and immunohistochemistry were used to detect coxsakie and adenovirus receptor (CAR) expression. Both localization and quantity were evaluated in the uteri obtained at days post coitus (dpc) 2.5, 4.5, 6.5, 8.5. Outcome of PCR was assessed by 2(-ΔΔCt) method. Image Pro-Plus 6.0 software was used for quantifying mean density of CAR expression in immunohistochemical sections. We found relatively weak CAR expression in the mouse uteri during implantation window. PCR and immunohistochemistry revealed highest CAR expression was detected on dpc 2.5 followed by down-regulation of CAR at dpc 4.5 and 6.5 (with significant difference). At dpc 8.5, CAR expression was increased slightly again. It is concluded that during implantation, the expression of CAR mRNA and protein is declined, resulting in the impairment of tight junction between cavity epithelium cells. After implantation window closure, CAR appears again to maintain epithelium stability. CAR might play an important role during embryo implantation procedure.
