Pseudomonas fluorescens is one of the most common contaminative bacteria of the stored blood. Ps. fluorescens No. 10-36 was cultured at 4℃, 22℃ and 37℃ for studying its growth phase and logarithmic growth phase. The results showed that this strain grew slowly at 37℃ with a generative rate of 900 minutes, but had no difference between the lag phase and the logarithmic growth phase. At 22℃ the lag phase were 5 hours, and the logarithmic growth phase were 29minutes, while at 4℃, the lag phase was 30 hours and the logarithmic growth phase was 300 minutes.

ObjectivesTo explore the impact of high body mass index (BMI) on irritable bowel syndrome (IBS) in Chinese adolescents.MethodsThe students were randomly selected from middle school and high school. They completed the epidemiological questionnaire of IBS and had their height, body mass measured.ResultsIn total, 1173 students were recruited, including 700 middle school students and 473 high school students. The incidence of overweight/obesity was 30.52%. The incidence of overweight/obesity was not significantly different between boys (28.40%) and girls (32.65%) (P=0.114), and there was not significantly different between students from middle school (30.57%) and high school (30.44%) (P=0.963). Two hundreds and twenty-one students suffered from IBS and the incidence of IBS was 18.84% with no significant gender difference. The incidence of IBS was significantly higher in students from middle school (13.43%) than those from high school (26.85%) (P<0.001). The incidence of IBS was not statistically significant be-tween overweight/obese students (22.07%) and normal weight students (17.42%) (P=0.061). The distribution of IBS subtypes had no statistical significance between overweight/obese and normal weight students (χ2=0.91,P=0.823). ConclusionsOverweight/obesity and IBS were extremely prevalent in Chinese adolescents, but the correlation be-tween them remains to be confirmed.

This study was aimed to determinate the content of quercetin from different parts (such as flowers, fruits, stems, leaves and branches) of Penthorum chinense Pursh. from Sichuan province so as to offer reference for the comprehensivedeve lopment and utilization of P. chinense Pursh. The quantitative determination of quercetin from five groups of different parts of P. chinense Pursh. were carried out and put into comparison by the reversed-phase high performance liquid chromatography (RP-HPLC). The results showed that there were larger differences of content among different parts. The highest content of the medical parts were flowers and fruits, which was followed by the leaves, stems and branches. It was concluded that different parts (such as flowers, fruits, stems, leaves and branches) of P. chinense Pursh. from Sichuan province should be divided in the clinical and productive practice, which was to supply the scientific basis for enhancing the curative effect and reasonable exploitation and utilization of the resource of P. chinense Pursh.

This study was aimed to analyze the influence of specific clinical effect of Dioscorea opposita Thunb. by dosage in order to summarize its rules. Recordings on pills containing D. opposita Thunb. from the classic prescrip-tion of the Formula Dictionary of Traditional Chinese Medicine were collected. Dosage of D. opposita Thunb. was used as the cardinal line. EXcellwas used to conduct schematic analysis. The results showed that small amount of D. opposita Thunb. had the effect of reinforcing the spleen. The effect of tonifying the lung had the dosage boundary line of 10 g. The small dosage had weak effect and large dosage had strong effect. The effect of tonifying the kidney was often the middle dosage. When the dose was larger or smaller, the effect was not obvious. The effect of consoli-dating the kidney was obvious when using larger or smaller dosage. It was concluded that the dosage of D. opposita Thunb. had relatively big influence on its effect, which provided reference of more value for the clinical practice and health cultivation.

0.05).Conclusion There are hapatic and renal disease,craniocerebral disease,wound,toxicaion with hypouricemia,the clinical assay should be paid more attention.

CYP2A6 is an important drug metabolic enzyme that plays a central role in pharmacology and toxicology.Coumarin and nicodine are mainly metabolized by it.CYP2A6 also have a close connection with diseases that related to smoking.While hnRNP A1 is a protein that shows an important regulative action on some specific genes at post-transcription level.Recently,researchers are paying more and more attention to the relationship between the activity of CYP2A6 and the expression of hnRNPA1.In order to master the change rule of CYP2A6 activity,we try to explain the regulative effect on CYP2A6 by hnRNP A1 at post-transcription level,which will bring an important effect on guiding clinical medicine treatments and smoking addictive therapy.

The human bronchial arteries and their anastomoses with pulmonary vessels were studied on normal and diseased lungs in 30 adult and infant cadavers under a magnification of 3～40 times.The bronchial arteries pursue a tortuous serpentine course along the surface of the bronchi. They divide either before or after the bifurcation of the bronchi and often send two branches coursing along each bronchus with one branch on each side of the bronchial wall. These branches usually form a network in the fibrous coat of the bronchus. Smaller twigs penetrate the bronchial walls and form a similar network in the submucosa.Mediastinal pleural branches and interlobar pleural branches of the bronchial arteries have their subpleural, independent course from the bronchial tree and their larger caliber at peripheral sites.In the visceral pleura and on the surface of the bronchi or within the bronchial wall, there are precapillary anastomoses between the bronchial and pulmonary arteries, and between the bronchial artery and pulmonary veins. The anastomoses occur either end to end or end to side.In the pleural adhesions of 9 cases of the lungs, the newly developed pleural branches arising from the intercostal, the superior intercostal, the pericardiophrenie or the internal mammary artery, anastomose with the bronchial artery via pleural arterial network to reinforce the blood supply for the diseased pulmonary area.The important physiological function of the anastomoses between the bronchial arteries and pulmonary vessels, as well as the course and distribution of the bronchial arteries in the lungs were discussed.

Objective To explore the relationship between adaptive skills and intelligence in young children. Method 30 young children aged from 3 to 6 years were concurrently administered the Adaptive Skill Rating Scale for Young Children(ASRSYC) and China- Wechsler Young Chilren Scale of Intelligence(C -WYCSI). Result The correlation coefficients between the total score of ASRSYC and the verbal scale score , performance scale score and full scale score of C - WYCSI were 0. 85, 0.70and 0. 81, respectively. The corrdlations between the total score of ASRSYC and the subtest scores of C - WYCSI ranged from 0. 51 to 0. 75 . Conclusion Adaptive skills and intelligenoe in young children relate each other and develop jointly.

Household questionnaire survey was conducted in 200 residents of Tilan and Zhanhqiao neighborhoods, Xingang community, Shanghai to know their awareness of knowledge about pulmonary tuberculosis (TB) prevention and treatment. Results showed that 87.0% of the residents surveyed knew TB symptoms, but only 42. 5% knew cough and expectoration were pulmonary TB symptoms, 76. 5 % knew that TB could not be transmitted by use something that was used by TB patients, 85.5 % knew government policy of free and payment reduction for TB treatment, and 82. 0% knew there existed some hospitals for TB treatment designated by local health administrations. There was significant difference in the awareness between the two neighborhoods ( P ＜ 0. 01 ). Factors related to their awareness of TB prevention and treatment knowledge included family annual income, educational level, publicity by telecision and broadcasting.
