OBJECTIVE:To establish a method for simultaneous determination of luteolin and apigenin in Mongolian medicine Scabiosa atropurea. METHODS:HPLC was performed on the column of Diamond C18 with mobile phase of acetonitrile-0.4%phos-phoric acid(34∶66,V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 350 nm,column temperature was 30 ℃,and the injection volume was 10 μl. RESULTS:The linear range was 66-396 ng for luteolin(r=0.999 8)and 93-558 ng for apigenin (r=0.999 6);RSDs of precision,stability and reproducibility tests were lower than 2%;recoveries were 98.15%-101.79%(RSD=1.42%,n=6) and 98.66%-104.05%(RSD=1.81%,n=6),respectively. CONCLUSIONS:The method is simple with good precise,stability and reproducibility,and can be used for the simultaneous determination of luteolin and apigenin in Mongo-lian medicine S. atropurea.

OBJECTIVE:To establish HPLC fingerprint sectrum of Rhaponticum uniflorum. METHODS:HPLC was performed on the column of Hypersil-ODS with mobile phase of 0.3% phosphoric acid-acetonitrile(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 220 nm,column temperature was 30 ℃ and volume injection was 10 μl. The luteolin was refer-ence,17 batches of R. uniflorum from different production places was analyzed and similarity evaluation system for chromatograph-ic fingerprint of TCM (2004 A edition)was adopted for the similarity analysis. RESULTS:There were totally 11 common peaks with similarity degree≥0.900 of 17 batches. According to the verification,the fingerprint spectrum and reference fingerprint spec-trum of R. uniflorum had good consistency. CONCLUSIONS:The established method is specific and stable,and can provide refer-ence for the identification and quality control of R. uniflorum.

Objective To study the change in blood-brain barrier (BBB) permeability in dog with craniocerebral gunshot injury and its significance. Methods Twelve dogs were randomly divided into control group, 15min ofter penetrating craniocerebral injury (PCI) group, 1h after PCI group and 6h after PCI group (n=3). The injury was produced by a small-calibre rifle made in Germany (type 5.56mm, weight of bullet 2.57g). Lanthanum nitrate was infused through the heart. The changes in BBB permeability were observed under electronic microscope. Results In 15min PCI group and 1h PCI group, changes in BBB permeability was observed, with manifestation of opening of tight junctions, with lanthanum nitrate particles passing through BBB into the brain tissues. These changes were more marked in 1h PCI group. Comparing with the above two groups, even more lanthanum nitrate particles were found in the brain tissue in the 6h group (P

Objective To investigate the exposure level of VOCs in different population and the health effects. Methods In 2005, a questionnaire survey relating to inhalation exposure assessment of VOCs and housing decoration characteristics was carried out in 200 newly decorated apartments (628 residents), 30 house decoration workers and 20 painting workers of an automobile manufacture factory. Indoor concentrations of formaldehyde, BTEX-compounds and TVOC were measured in typical apartments, offices, houses in where the decoration workers were operating, the painting workshops, and public indoor environments. Average daily exposure doses and potential doses for common people at home (non-occupational exposure group) and workers in occupational environments (occupational exposure group) to formaldehyde and BTEX-compounds and TVOC were estimated by combining the survey results with monitoring data. Results The percentages of whom having different discomfortable symptoms in the workers in the painting workshop were higher than that in common people (P

Objective To study the gene expression and the expression change rule of c-fos in the canines posterior to craniocerebral gunshot wounds in order to provide the experimental base for further understanding of the mechanism of gunshot craniocerebral injury. Methods Using the canine model of penetrating craniocerebral injury made by the bullets of the small-calibre rifle made in Germany, the c-fos expressions in the control cerebral tissues and the contusion and concussion areas of the trajectory and the brain stem neurons at different time points after trauma were observed by immunohistochemical method. Results Feeble c-fos expression was detected in the control group. After craniocerebral gunshot wounds, the c-fos expression increased in the contusion and concussion areas of the trajectory and in the brain stem at the 30th minutes, reached the peak at the 2nd hour and began to decrease at the 3rd hour. The c-fos expression in the concussion area was much more significant than that in the contusion area ( P

imaging features of myositis ossificans have some characteristics. Misdiaguosis could be avoided when the disease was evaluated with the course.

OBJECTIVE:To establish the quality standard for Mongolian medicine Yishen powder. METHODS:TLC was used for the qualitative identification of Rheum palmatum and Terminalia chebula in the preparation;HPLC was used for the contents de-termination of aloe emodin,rhein,emodin,chrysophanol and physcion:the column was Inertsil C18 with mobile phase of metha-nol-0.1% phosphoric acid(gradient elution)at a flow rate of 1.0 mL/min,detection wavelength was 254 nm,column temperature was 35 ℃ and the injection volume was 10 μL. RESULTS:The TLC pots of R. palmatum and T. chebula were clear and well-sepa-rated,negative control without interference. The linear range was 23.55-117.75 ng for aloe emodin(r=0.9999),44.72-223.62 ng for rhein(r=0.9998),43.18-215.90 ng for emodin(r=0.9997),77.41-387.12 ng for chrysophanol(r=0.9999)and 46.02-230.10 ng for physcion (r=0.9997);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 95.80%-99.66%(RSD=1.21%,n=6),95.01%-98.07%(RSD=0.92%,n=6),95.06%-97.84%(RSD=0.5%,n=6),95.19%-97.66%(RSD=1.07%,n=6)and 95.07%-98.20%(RSD=0.95%,n=6). CONCLUSIONS:The established standard can be used for the quality control of Mongolian medicine Yishen powder.

Objective To study the changes of iodine source and the nutritional status of iodine after termination of iodized salt supply in the areas with different water iodine concentrations in Shanxi province,in order to provide scientific bases for developing strategies on control and prevention of iodine deficiency disorders,and to study the cut-off value of water iodine level where iodized salt supply should be stopped.Methods In 2010 in Shanxi province,6 villages with 100％ of non-iodized salt consumption rate were selected as the survey spots based on the iodine concentration in drinking water of 0-,50-,100-,150-,300-,≥500 μg/L.Villages'iodized salt supply was terminated thoroughly.In each village,20 children aged 8 to 10 were selected.At the same time,women of childbearing age 18 to 50 years old and adult men aged 18 to 60 were selected from the same families as the children.Diet surveys were conducted by the method of 3 days recall on all subjects.Drinking water samples,staple foods,supplementary foods and urinary samples of all subjects were collected and the iodine concentration was determined by arsenic-cerium catalytic spectrophotometry.Results ①In the villages of water iodine 25.9,70.6 μg/L,the medians urinary iodine of children,women and men were all ranged from 100 to 199 μg/L,which meant their iodine nutrition levels were appropriate.In the village of water iodine 109.0 μg/L,the medians urinary iodine of children,women and men were all ranged from 200 to 299 μg/L,which meant their iodine nutrition levels were more than appropriate.In the villages of water iodine 225.8,430.0,581.2 μg/L,the medians urinary iodine of children,women and men were all ≥ 300 μg/L,which meant their iodine nutrition levels were too high.②)In all the 6 villages,the intaking amount of iodine met and exceeded the standard recommended intake of dietary iodine by ICCIDD/UNICEF/WHO (8 to 10-year-old children ≥ 120 μg/d,women of childbearing age and adult men ≥ 150 μg/d).But in the village of water iodine 581.2 μg/L,the iodine intake was exceeded the daily maximum safe intake (children aged 8 to 10 ≤800 μg/d,women of childbearing age and adult man ≤ 1000 μg/d).③The amount of iodine ingestion from drinking water was increased with the water content of iodine.When water iodine exceeded 100 μg/L,the amount of iodine ingestion from drinking water was higher than from food intaking,and became a main resource of iodine in the human body.Conclusions In the counties of iodine concentration in drinking water above 100 μg/L in high iodine areas of Shanxi province,the water iodine becomes the most important source of iodine,and iodine nutritional level is more than appropriate or possible excess.It is recommended that in areas of high water iodine of Shanxi province,the standard cut-point of water iodine value is set to 100 μg/L.
