Objective To study the therapeutic effect of sub-hypothermia on 80 patients with diffusing axonal injury (DAI) and its prognosis.Methods All 80 patients with DAI were randomly divided into the sub-hypothermia group(40 cases)and the control group(40 cases). All patients'vital sign,intracranial pressure (ICP) and blood sugar were measured. 40 cases of the patients with DAI were treated by sub-hypothermia, the rectal temperate (RT) reached 32 0℃~35 0℃,sub-hypothermia lasted for 1~7 days; the control group was treated routine. According to Glasgow Outcome Scale (GOS), the prognosis of the patients was evaluated 3 months later.Results In comparison with the control group, increased ICP and raised blood sugar in sub-hypothermia group were significantly decreased (P

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 establish the model of palatine mucoperiosteal expansion and observe a new possible treatment approach to soft tissue defect of cleft palate. Methods: Expanders of 10ml were implanted beneath the palatine mucoperiosteum in 4 dogs and injected 1.0ml 0.9% NaCl at the same time. 20 days after the placement of the expander, the expander was expanded by 1.0-1.5ml every 7 days again. The dogs were killed after the expanders reached their capacity. All the specimens were performed histomorphometric and histological examinations. Results: Histological results showed the increase in the layer of cell and the number of collagen fibra and blood vessel. All the specimens of expanded tissue showed the formation of extra palatine mucoperiosteal tissue. Conclusion: Expansion technique is able to form extra palatine mucoperiosteal tissue,which could be a new restoration approach to soft tissue defect of cleft palate and others.

Objective The aim of this study is to investigate CD+8 natural killer T cell receptors NKG2D and NKG2A expression in peripheral blood of patients with lung cancer and discuss the relation between imbalance expression of NKG2A and NKG2D and tumor immune escape. Methods Flow cytometry was used to determine the percentage of NKG2D and NKG2A-expressing of CD+8 NKT cells in peripheral blood of 95 untreated lung cancer patients and 50 healthy controls. Results NKG2D was lower expressed on CD+8 NKT in lung cancer, the level of NKG2D in patients (77.07±5.77) % was significantly lower than that in the controls (84.13±4.49) % (t =8.14, P <0.05). In the TNM stage, the level of NKG2D in patients of Ⅰ-ⅢA, ⅢB, Ⅳ stage were (81.07±5.02) %, (76.95 ±4.70)%, (72.80±5.16) %, respectively, the level of NKG2D was significantly decreased in order (F =18.74, P <0.05). NKG2A was expressed higher on CD+8 NKT in lung cancer, the level of NKG2A in patients (33.58±8.82) % was significantly higher than that in the controls (25.31 ±8.38) % (t =-5.46, P<0.05). In the TNM stage, the level of NKG2A in patients of Ⅰ - Ⅲ A, ⅢB, Ⅳ stage were (25.10±6.93) %, (33.24±3.76) %, (43.64±6.10) %, respectively, the level of NKG2A was significantly increased in order (F =75.73,P <0.05). Conclusion Imbalance expression of NKG2A and NKG2D may restrain the function of CD+8 NKT cell of lung cancer patients in peripheral blood and that may be one of important factors in tumor immunological escape.
