Objective To evaluate the effect of non-linear blending function for dual-energy CT on image of pulmonary angiogra-phy.Methods 27 patients underwent dual energy CT pulmonary angiography(CTPA).Data obtained with 100 kVp,140kVp,and non-linear blending were divided into group A,B,and C respectively.CT value of emboli were measured.Corresponding signal to noise ratio(SNR )and contrast to noise ratio(CNR)were calculated.One-way Anova analysis and Friedman test were used to ana-lyze statistical significance among these values.Results On quantitative analysis of 27 patients,there was no statistical difference for CT value of CTPA among the three groups(P >0.05).For the noise,CNR and SNR,there were statistically significant among the three groups(P <0.05).Conclusion The non-linear blending function has certain advantages in improved image signal-to-noise ratio and it can be used in CT pulmonary angiography examination for patients suspected pulmonary embolism clinically .

Objective To determine the efficacy of glucose-loweringtreatment by proton magnetic resonance spectroscopy (1H-MRS).Methods Bilateral frontal lobes of 45 male patients with type 2 diabetes mellitus (T2DM) underwent 1 H-MRS separately bythe time it was first diagnosed.Among them,30 were treated with insulin,15 were rejected.The bilateral frontal lobes of all patients were re-examined with 1 H-MRS after 6 months.The ratios of metabolites in the frontal lobe were recorded and compared,and observing whether the lactate(Lac) peak appeared or not.Results Significantly higher values of the N-acetylaspartate (NAA)/creatine (Cr)ratio and NAA/choline (Cho) ratio after 6 months (2.414 2± 0.206 6 and 2.244 2±0.341 5) were found in bilateral frontal lobes compared with pre-therapy (1.905 3±0.135 7 and 1.906 0±0.322 1)(P<0.05).Significantly lower values of the NAA/Cr ratio and NAA/Cho ratio in the refuse treatment group(1.504 2 ± 0.262 4 and 1.510 0± 0.220 8) were found in bilateral frontal lobes compared with pre therapy (1.960 0±0.175 0 and 1.880 8±0.297 0)(P<0.05).Lac peak was not detected in the all experiments.Conclusion 1 H-MRS provides valuable information in the assessment and evaluation of clinical efficacy and prognosis of T2DM by detecting the changes of brain metabolism.

OBJECTIVE: To set up a natural degeneration model of chondrocytes derived from endplate of intervertebral discs of rats in order to offer an appropriate carrier for the study on mechanism of intervertebral disc degeneration. METHODS: The method of enzyme digestion combined with natural subculture was used to set up the in vitro natural degeneration model of chondrocytes derived from the endplate of intervertebral disc of rats. The morphological appearances and microstructures of the chondrocytes of different generations were observed. The expression of collagen II in chondrocytes was detected by immunocytochemical method. RESULTS: The chondrocytes derived from the endplate of intervertebral disc expressed collagen II. After 13 days of culture, the chondrocytes of generation III showed that the ability of cell division descended, the nucleoli became unclear, the cells deformed obviously, fusiform shape with weak optical activity appeared, and the intercellular space was enlarged. There were vacuoles and lipid droplets in cytoplasm. The synthesis of collagen II, as well as the cell proliferation rate, descended notably. All results showed the natural degeneration process of the chondrocytes. CONCLUSION: The in vitro natural degeneration model of chondrocytes derived from endplate of intervertebral discs of rats was successfully established. This can offer the cytological basis for study on the mechanism of intervertebral disc degeneration.

Objective:
To assess the health risk associated with drinking water in Hangzhou from 2016 to 2017,and to provide evidence for the safety of drinking water .
Methods:
The monitoring data of 5 genetic toxic substances(arsenic,hexavalent chromium,cadmium,chloroform,tetrachloromethane)and 13 body toxic substances(lead,mercury,selenium,cyanide,fluoride,nitrate,iron,ammonia nitrogen,manganese,copper,zinc,aluminum,volatile phenol)from 36 source water samples,36 finished water samples and 288 tap water samples in the main urban areas of Hangzhou were collected from 2016 to 2017. The health risk of drinking water containing the chemical pollutants mentioned above were assessed based on the evaluation models recommended by United States Environmental Protection Agency .
Results:
The concentrations of 5 genetic toxic substances and 13 body toxic substances in source water,finished water and tap water were all within the reference limits issued by Standards for Drinking Water Quality(GB 5749—2006). The carcinogenic risk,non-carcinogenic risk and total health risk caused by the chemical pollutants in the source water were 2.18×10-5/a,7.75×10-9/a and 2.18×10-5/a. The carcinogenic risk,non-carcinogenic risk and the total health risk caused by the chemical pollutants in the finished water were 1.08×10-5/a,3.70×10-9/a and 1.08×10-5/a. The carcinogenic risk,non-carcinogenic risk and total health risk caused by the chemical pollutants in the tap water were 1.96×10-5/a,3.61×10-9/a and 1.96×10-5/a. The carcinogenic risk and total health risk caused by chemical pollutants ranged from high to low in the source water,tap water and finished water. The non-carcinogenic risks ranged from high to low in the source water,finished water and tap water .
Conclusion
The health risks of 18 chemical pollutants in drinking water in Hangzhou were at a low level,with the greater carcinogenic risk than the non-carcinogenic risk. Hexavalent chromium had the highest carcinogenic risk,while fluoride and aluminum had the highest non-carcinogenic risk.

OBJECTIVETo develop an HPLC method for determination of the four effective components (genistin; rutin; quercetin; genistein) in Huaijiao pill.
METHODThe chromatographic separation was performed on a Shim-packODS (4.6 mm x 150 mm, 5.0 microm) eluted with a mobile phase of MeOH-H2O-HAc (40:60:0.25). The detection wavelength was set at 256 nm and column temperature was set at 30 degrees C .
RESULTNice linear relation between the peak area and injected amount exists when the amount is within 0.059-0.352 microg for genistin, within 0.435-2.610 microg for rutin, within 0.020-0.121 microg for quercetin and within 0.053-0.319 microg for genistein. The correlation coefficient of each component is 0.999 6, 0.998 2, 0.998 9 and 0.999 9 respectively. The average recoveries of the four components are from 98.7% to 100.2%. The RSD of each group are 1.21%, 1.36%, 0.47% and 1.54% (n = 5).
CONCLUSIONThe method was accurate, repeatable and suitable to determine four effective components in Huaijiao pill. It can be use for quality control of Huaijiao pill.
