Objective:To investigate the effects of purple sweet potato flavonoids (PSPF)in the extracts with different polarity on the insulin resistant HepG2 (IR-HepG2) cells.Methods: PSPF in the extracts with different polarity was used to intervene the IR-HepG2 model, and the remaining glucose concentration in the IR-HepG2 group and PSPF intervention groups was compared .Results:The remaining glucose concentration in PSPF intervention group , PSPF with chloroform as the extracting solvent at high , medium and low dose of PSPF , and PSPF with butanol as the extracting solvent at high and medium dose of PSPF was obviously lower than that in the IR-HepG2 group(P<0.05).Conclusion:PSPF, the chloroform extract of PSPF and the butanol extract of PSPF can enhance the consumption of glucose in IR-HepG2 cells.

To investigate the children's food habit, one thousand of children from eleven elementary school food service were randomly selected in Taejon. The survey was conducted by questionnaires and data were analyzed by SAS program. The results are summarized as follows. 1. The average height and weight for the 3th grader are 132.0cm and 29.4kg for boys. 131.2cm and 27.9kg for girls. In the case of the 6th grader the average height and weight are 147.1cm, 41.1kg for male, 148.6cm, 41.0kg for female, repectively. Those values are less than national averages. 2. The third grader eats breakfast more regularly than the sixth grader(p<0.001) and 51.5% of the children answer that they take foods for their health. The third grader has better eating habits than the six grader. This survey shows that the sixth grader eat more cereal, milk and vegetable and the third grader has less fruits than the sixth grader. 49.3% of the total children likes eating food at home, 36.6% eating outsid and 14.1% school meal service. 25.8% of the children reply that they do not eat now foods during school meal service. 82.5% of the total children are willing to eat foods served from school meal service if a teacher explains about the information of foods.

This study was carried out to provide the improvable way of foodservice management to dietitian in the elementary schools. For this purpose the serving pattern of food, menu planing, nutrition education, leftover management and difficulties in foodservice were investigated. The survey was conducted through questionnaires, which were collected from 249 dietitions randomly selected in Taejon and Chung Nam. Data were analyzed by SAS program. The main results of this study are as follows. The children in Taejon took foods in the class room(65.7%) and those in Chung Nam in the dinning hall(89.9%)(p<0.01). In menu planning the balance of nutrition(42.6%) was mainly considered and then food preference(19.7%), variety of menus(16.1%), food cost(16.1%), composition of food color, taste and texture(3.2%), skills of food making(1.6%) and the number of students(0.8%). They referred cooking magazines(47.7%), the previous menu(42.2%), children's opinion(7.2%) for planing menu. The insufficiency of implements and devices for food(24.1%) and lack of season's food(20.4%) were indicated as difficulties in their job. 34.5% of dietitians used a standard menu, 79.5% investigated food preference of children, 74.3% evaluated taste of foods before serving, and 80.7% regularly checked leftover. The major reason for leftover was careless of the teacher in charge in Taejon and bad taste of foods nutrition in Chung Nam(p<0.001). 98.5% of them answered that they had the responsibility for nutrition education in elementary school. They had a hard time in relationship with the staffs in school(40.6%) and employees for food(39.8%), and lack of market information(38.2%). To efficiency of dietitian's work can be enhanced by reflecting the results of children's food preference and leftover, by using standard cooking method and proper cooking utensil, and by performing nutrition education for children by themselves.

This study was done to provide basic information for nutrition education and meal planning by analyzing children's food preference. For this purpose, 938 children from eleven elementary schools under meal service were randomly selected in Taejon. The survey was conducted by questionnaires, and data were analyzed by SAS program. Children prefered ssalbap to japkogbap and liked kimbap the best among one dish foods. But their most favorite foods were chajangmyun in noodles, miyeokkuk in soups, and chamchichigae in pot stew. Sixth graders like kimchichigae more than third graders. In the case of chims, children like duejigalbichim, sogalbichim, and dalgyalchim. In the jorim, they prefered duejigogi jangjorim, mechurial jangjorim to any other jorims. The preference of bockum, namul, jangachi, and jotgal is generally low. Children's preference is high in fruit, drink, fried food, one dish food and is low in jangachi, namul, bockum. These results suggest that the preference of foods should be fully taken into consideration in school meal service so that they can eat foods with pleasure. Foods, which are low in preference due to the cooking method, should be prepared with new cooking methods developed specifically for children. 'Even though the preference of food is low to the children, the nutritious foods should be utilized in the school menu. Then, the imporatance of food intake must be taught to them through nutrition education.

OBJECTIVETo study the function of the chalcone synthese gene introns in Scutellaria baicalensis, and clarify preliminarily their role in abiotic stress.

METHODThe CHS introns with specific primers were cloned and bioinformatic method was applied to predict the cis-elements in the intron of CHS. The introns were subcloned into binary vector, pCAMBIA-1301 before being transferred to tobacco. Then the activity of GUS of the transgenic tobacco seeds was analyzed.

RESULTSeven cis-elements were found in the introns. Under the dark and high temperature GUS expression rose at the first (3 h), but then declined (9 h). ABA and MeJA regulated insignificantly the GUS activity in normal temperature; treatment of 10% PEG induced GUS expression.

CONCLUSIONCHS introns could be play a role in the regulation of S. baicalensis phenylpropanoid biosynthetic pathway.

Objective To analyze the incidence and risk factors of de novo hepatitis B virus (HBV) infection from anti-HBc-positive donors in pediatric living donor liver transplantation and to explore the diagnosis and treatment.Method A retrospective analysis was conducted on 105 cases of pediatric living donor liver transplantaions (LT) perfomed during September 2006 to December 2013.HBV markers,including hepatitis B surface antigen (HBsAg) and antibody (anti-HBs),anti-HBc,hepatitis B e antigen (HBeAg) and antibody (anti-HBe) were determined in both donors and recipients before LT and in recipients after LT.HBV DNA titer was measured if the recipients were strongly suspected of de novo HBV infection.Result After 4 perioperative deaths were excluded,101 cases were studied.The median follow-up period of all the patients was 20.5 months (2.7-97.7 months).de novo HBV infection occurred in 6 of 101 recipients (5.9％) 3.5 18 months after LT.Forty-four (43.6％) of the children received HBcAb-positive allografts,and 11.4％ (5/44) of the children were had de novo hepatitis B infection.All five of the HBV-infected children received HBcAb-positive allografts without preventive treatment in 11 cases (5/11,45.5 ％),57 (56.4％) of the children received HBcAb-negtive allografts,and 1.7％ (1/57) of the children had de novo hepatitis B infection.Conclusion Anti-HBc-positive donors can significantly increase the incidence of de novo HBV infection in HBsAg-negative recipients without preventive treatment.with the appropriate treatment strategy,HBcAb allografts can safely used in pediatric recipients.

Objective To investigate the hMOF protein expression in non?small cell lung cancer and explore the relationship between its expres?sion and radiotherapy prognosis. Methods Immunohistochemical staining was used to detect the hMOF expression in 59 cases of non?small cell lung cancer after radiotherapy. The relationship between hMOF expression with clinicopathological and radiation prognosis was analyzed. Results Among the 59 cases of non?small cell lung cancer tissues,there were 30 cases found to be high expression with hMOF. The rate of positive expression of hMOF in non?small cell lung cancer were 50.85%. Clinical stage and hMOF expression were independent predictors for non?small cell lung can?cer. Conclusion The expression of hMOF had a positive correlation with the radiation prognosis in non?small cell lung cancer,which could be used as a prognostic indicator of radiotherapy.
