Objective To investigate the relationship between the levels of serum glial fibrillary acidic protein (GFAP) ,ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) ,CT findings and outcome in patients with severe traumatic brain injury .Methods En-zyme linked immunosorbent assay (ELISA) was conducted to detect the serum level of GFAP and UCH-L1 in 62 patients with se-vere traumatic brain injury at the time of 12 h and 36 h after the trauma .CT scans of the brain were obtained within 12 h of injury . Outcome was assessed by glasgow outcome scale (GOS) at 6th month .The relationship between GFAP ,UCH-1 ,CT findings and outcome were analyzed .56 healthy persons were selected as control group .Results The concentrations of serum GFAP and UCH-L1 of patients were significantly higher than those of the control group (P< 0 .05) ;GFAP levels were higher in patients with mass lesions than in those with diffuse injury while UCH-L1 levels were higher in patients with diffuse injury (P< 0 .05) ;the levels of GFAP and UCH-L1 of patients with unfavourable outcome(GOS 1 - 3 scores) were significantly higher than those of patients with favourable outcome(GOS 4 - 5 scores) ,and the concentrations of biomarkers were significantly negatively correlated with outcome . Conclusion Serum levels of GFAP and UCH-L1 are good predictors for severity and outcome in severe traumatic brain injury (TBI) .The levels of GFAP and UCH-L1 could reflect different injury pathways which were different in patients with mass lesions and diffuse injury remarkbly .GFAP and UCH-L1 could provide better characterization of subjects for specific types of cellular dam -age than that obtained with CT alone .

Objective To investigate cause and prevention of dysuria after hyperplasia of prostate operation. Methods To analyze 66 cases of dysuria after hyperplasia of prostate operation retrospectively. Result The most common reasons to dysuria are orderly stenosis of bladder neck; inflammatory edema of bladder neck; urethral stricture; rehyperplasia of remained prostate tissue; neruogenic bladder; prominence of ureteral crest; clot obstruction. Conclusion Prevention of dysuria after hyperplasia of prostate operation consists in preoperative satisfied diagnosis and correct treatment in operation and after operation.

Objective To evaluate the influence of gaseous combustion products of the natural gas (NG), liquefied petroleum gas (LPG) and coal on the indoor air quality. Methods The three kinds of domestic fuels were burned in the designed experimental rooms and the concentrations of SO2, NO2, CO and formaldehyde in the indoor air were determined according to the standard methods at the same time, the emission characteristics of SO2, NO2, CO in these fuels were analyzed also. Results The emission level of CO was the highest in the four combustion products of all three fuels. According to the average daily usage in general families in China, the emission of CO in the coal combustion was much higher than that in combustion of NG and LPG. The unit emission of CO of the coal for house use could reach 30 136 mg/kg, much higher than LPG(8 725 mg/kg)and NG(2 755 mg/kg). The unit emissions of NO2 of LPG combustion (42.69 mg/kg) was higher than the coal and NG (20.01 mg/kg, 11.87 mg/kg), so in the unventilated rooms it could still make the indoor air quality exceed Chinese indoor air quality standard limits. Conclusion Burn of NG or LPG in the kitchen could also cause indoor air pollution.

Objective To develop a method for determining cyanogen chloride (CNCl) in drinking water. Methods Pyridine-barbituric acid spectrophotometry was employed and some parameters including the pH value of the phosphate buffer, the time of color reaction, temperature, the concentration of chloramine T, the proportion of the phosphate buffer, the proportion of color agent and the maximum absorption wavelength were optimized. The linear range, limit of detection, precision and recovery rate were studied. Results Trace quantity of CNCl obeyed the Law of Beer. In the range of 0-0.1 ?g/ml CN-, the correlation coefficient was 0.999 4, the regression equation was y=0.194x-0.033, the limit of detection was 0.003 ?g/L, the lower limit of detection was 0.01 mg/L, the relative standard deviations were 1.5%-6.2% and the recovery rates were 92.9%-107.1%. Conclusion The method has the characters of accurate, sensitive, simple and rapid, it can be used in monitoring of drinking water quality.

Objective To get knowledge of the indoor air pollution states in the newly renovated apartments in Xi’an city, and explore the relationship among the major pollutants and the relationship between the pollutants and the differences of seasons. Methods From January, 2006 to May, 2007, we randomly selected 138 newly renovated (3 months or less) apartments in the urban area of Xi’an city, tested their indoor (including bedrooms, living room, dining room, kitchen, bathrooms, study, a total of 597) content of formaldehyde, total volatile organic compounds (TVOCs), ammonia, benzene, toluene and xylene. Results Among which were detected in all of the pollutants, total volatile organic compounds (TVOCs) and formaldehyde own the highest exceeding rates, respectively 69.8% and 60.8%. They are followed by ammonia, whose exceeding rate is 13.2%, xylene which has the highest exceeding rate among the benzene compounds, 8.7%. We did comparative analysis of the concentration in different types of rooms for the pollutants which are among the top four in exceeding rate ranks, and found that only for formaldehyde, there is significant difference in statistics (P

Objective To study the status of knowledge-attitude-practice (KAP) of environmental health among urban and rural residents and the influencing factors. Methods Totally,4 607 urban and rural residents from Lanzhou,Taiyuan,Shanghai and Qingdao were recruited and investigated by the self-designed questionnaire from July 3rd to August 10th 2007. In the questionnaire,a certain number of related questions were designed mainly on environmental health knowledge,attitude and practice. The datas were analyzed with SPSS13.0 software. Results The average scores of environmental health knowledge,attitude and practice of urban and rural residents were 4.14?1.30,4.88?0.85 and 4.05?1.11 respectively.

Forty-five patients with peritonsillar abscesses(PA) were treated by needle aspiration. Pus was drawn in 89%(40/45) of the cases at the first aspiration and repeated aspiration was necessary in 33%(15/45) of the patients. All of the patients were cured by needle aspiration without further invasive therapy and no serious complication was observed. 32 out of 45 patients were available for follow-up. Among them, three had another recurrent PA in situ and the other ten(31%) had recurrent tonsillitis. However, analysis showed that the patients under 35 years of age had higher recurreuce rate of PA of recurrent tonsillitis than those over 35 years old(P
