Objective To know the primary effect of nutrition intervention in farmers. Methods The questionnaires were used to do baseline and evaluation survey. The intervention ways were used in trial group, including holding lectures, posting posters, sending out healthy material, quizzes with prizes, recommending salts low in sodium to each family, training to make healthy food by the chef; but there were no measures in control group. Results There were statistical significance in healthy awareness of nutrition, exercises and chronic diseases between two groups after intervention; However, the average intake amounts of vegetables did not reach the recommendation of diet guidelines; After intervention, the intake frequency of vegetables and fruits had statistical significance between before and after intervention in trial group, and also had statistical significance in two groups. Conclusion The awareness of healthy knowledge and attitudes has been obvious improvement, but the diets and life styles of farmers have no obvious change. The diet structure and behavior of farmers have been increasingly rational but not enough. The farmers have started to increase the intake times of vegetables and fruits and built up the conception of eating more vegetables and fruits.

Objective To investigate the effect of 12-lipoxygenase (12-LO) on the angiotensinⅡtype 1 receptor(ATlR) expression in mesangial cells (MC).Methods p38 MAPK activation and ECM protein expression were determined using AngⅡ-stimulated MC derived from normal and 12-LO knockout mice.AT1R expression was determined using 12-LO product 12(S)- HETE-stimulated MC,MC transfected with 12-LO gene and microdissected glomeruli derived from 12-LO knockout mice.RT-PCR and Western blot were used for evaluating mRNA and protein expression respectively.Results AngⅡstimulation increased p38 MAPK activation and ECM protein expression in normal MC,but not in MC derived from 12-LO knockout mice.Time-dependent and dose-dependent experiment showed that 12 (S)- HETE increased AT1R protein' expression in MC. Similarly,12 (S)-HETE increased AT1R mRNA expression in MC compared with control MC (P<0.01). Furthermore,AT1R expression was lower in glomeruli derived from 12-LO knockout mice relative to genetic controls (P<0.01) and MC stably overexpressing 12-LO had greater AT1R protein and mRNA expression relative to control MC (P<0.01).Conclusion 12-LO activation can upregulate ATIR expression in MC.

Targeting induced local lesions in genomes (TILLING) is a reverse genetics method for functional genomics research.It is possible to screen for point mutations in the populations of EMS mutagenesis with highthroughput and lowcost. EcoTILLING a method based on TILLING ,was developed for detecting multiple types of polymorphisms in germplasm collections,such as single nucleotide polymorphism,small deletion and insertion etc.Rice is a very important food crop and a model plant for genome research also. There are complete genome sequence and a lot of other bioinformatics resources about it.So the markerassisted breeding is becoming more and more important in rice breeding. Some issues based on TILLING about identifying germplasm based on gene sequence,EMS mutagenesis breeding,developing functional marker in rice breeding in future were discussed.

Objective To investigate the imaging findings of the lacerating injury of the lung. Methods Ten patients of lung lacerating injury were examined by X-ray and CT within 1—5 h after injury. X-ray(2—5 times)and CT(3—5 times)examinations were repeated for 7 patients.Results The lung lacerating injury involved 10 sides and 14 lung lobes(21 lesions in total)in the 10 cases,among which 1 case involved the right upper lobe with 1 lesion,2 cases in the right lower lobe with 2 lesions,1 case in the right upper and lower lobes with 2 lesions for each lobe,3 cases in the left lower lobe with 9 lesions,and 3 cases in both the left upper and the lower lobes with 7 lesions.The X-ray findings were cavity-like shadows with smooth margin in 9 lesions(9/21),and patchy shadows of fogging margin in 12 lesions(12/21).The CT imaging findings included 6 pulmonary hematomas(6/21),and 15 cavitary lesions with air-fluid levels (15/21).In the 15 cavitary lesions,CT revealed 14 single cavities and 2 small cavities within a big cavity. On dynamic follow-up observation,the cavity was the biggest in 1—5 h after injury,but the hematoma was the biggest in 2—3 days after injury.Hematomas tended to absorb slower than the cavities.After 16— 32 days,all lesions revolved into small patchy or stripe-like shadows with slightly increased density. Conclusion Cavitary lesion with air-fluid level is the characteristic imaging finding of lung lacerating injury.CT surpasses X-ray plain film in revealing the details of lung lacerating injury.

Background Research showed that exposure of 530 nm monochromatic light can induce myopia in animal,and retinal Müller cells participate in the formation of myopia.However,the effect and mechanism of retinal Müller cells during the formation of monochromatic light induced-myopia is below understood.Objective This study was to investigate biologic characteristics of rat retina Müller cells and the expression of cell factors in Müller cells after being illuminated by the 530 nm monochromatic light,and discuss the role of the retina Müller cells in myopia induced by monochromatic light.Methods Immortalized rat retinal Müller cells were cultured with DMEM containing 10% fetal bovine serum in a self-made cell incubator with monochromatic light by adjusting luminance of 530 nm LED source.The cells were exposed to 125,250 and 500 lx luminance respectively for 6,12 and 24 hours,and the cells without light-irradiation were used as control.The growth of the cells under the different light time and different illuminations was described by MTT as the absorbance at the wavelength 570 nm (A570),and cell cycle analysis of Müller cells was performed by flow cytometry 48 hours after cultured,and the expression of transforming growth factor-beta 1 (TGF-β1),tyrosine hydroxylase(TH),inducible nitric oxide synthase(iNOS) and basic fibroblast growth factor(bFGF)in the cells were detected by reverse transcription PCR(RT-PCR),respectively.Results The Müller cells were uniform in size with polygonal shape and defined edges.No statistically significant difference was found in the A570 value in the cells of the 125 lx and 250 lx illuminated groups compared with the control group in various time points(P>0.05).However,significant lowing was seen in the A570 value in the cells of the 500 lx illuminating for 12 hours and 24 hours in comparison with the control group (P =0.013,0.001).Compared with the control group,the ratio of the number between G2 and G1 phase was not significantly declined in 125 lx,250 lx illuminating for 48 hours (P =0.073,0.330),and the ratio in the 500 lx illuminating group was significantly lower than those in the 250 lx illuminated group and the control group (P =0.028,0.038).RT-PCR revealed that the expression of TGF-β1 mRNA in the cells was higher in the 250 lx illuminated group than that of the 500 lx illuminated group (P=0.006).The expression of iNOS mRNA was gradually upregulated in the 250 lx illuminated group compared with the control group (P =0.001),but that in the 500 lx illuminated group was downregulated (P =0.000).The expression of bFGF mRNA was raised in the 125 lx and 250 lx groups but reduced in the 500 lx group when compared with the control group(P=0.002,0.000,0.005).Also,the expression of TH mRNA was significantly increased in the 250 lx group(P=0.000),but decreased in the 500 lx group(P=0.000,P=0.001).Conclusions The monochromatic light of 530 nm can inhibit the growth of rat Müller cells and downregulate the expression of myopia-related cell factors and therefore exert effect in the formation of myopia.
